Different concentrations and volumes of p‐phenylenediamine in pet. (equivalent doses) are associated with similar patch test outcomes: a pilot study

Abstract: Background Concern about causing active sensitization when patch testing is performed with p-phenylenediamine (PPD) 1% pet. has led to a recommendation to use PPD 0.3% pet. as a potentially safer preparation. However, the dose per area of allergen delivered, and hence the risk of active sensitization, depend on the amount dispensed into the patch test chamber, which can vary widely. Objective To evaluate whether patch testing with equivalent doses of different concentrations of PPD in pet. is associated with similar outcomes. Methods Seventeen known PPD-sensitive subjects were patch tested with different volumes and concentrations of PPD in pet. that deliver the same allergen dose per unit area (6 mg of PPD 1% pet. and 20 mg of PPD 0.3% pet. in Finn Chambers®, both equivalent to ∼ 0.09 mg/cm2 ). Results Eleven patients (65%) had positive reactions to both doses; 4 patients (24%) had negative results [percentage agreement of 88% (15/17)]. One patient each had a positive reaction to only one dose. Conclusions The 88% concordance suggests that dose per unit area is more important in determining reactions to allergens than the excipient volume dispensed. Patch testing with a smaller volume of 1% PPD may be a reasonable alternative to testing with 20 mg of 0.3% PPD.

Plug connector part having a temperature sensor device

Abstract: A plug connector part for connecting to a mating plug connector part comprises at least one electrical contact element for conducting an electric current and for producing an electrical contact which has at least one other contact element of a mating plug connector part and a temperature sensor device for detecting a warming of the plug connector part. Thereby, the temperature sensor device (43) comprises at least one sensor element (431, 431B-431E), which is designed to detect an infrared radiation emitted from the at least one electrical contact element (42B-42E). In this way, a plug connector part comprising a temperature sensor device is achieved which can swiftly identify an (excessive) heating on one of the contact elements and hence allow countermeasures to be initiated quickly.

Coding element e.g. elongated formed coding key used in groove-shaped recess of plug connection arrangement, has recess portion that is formed in region of bulge portion between training side surfaces of changing width portion

Abstract: The coding element (1) comprises a changing width portion that is provided with training side surfaces (2,3) on opposite sides to set width of the coding element main portion. A recess portion (4) is formed in region of a bulge portion between the training side surfaces of the changing width portion. An independent claim is included for plug connection arrangement.

Electrical distribution device and method for fitting the same

Abstract: The subject matter of the invention is an electrical distribution device (10), in particular a distribution piece, for connection to line and/or connecting devices (12) which have shielding devices (18), wherein the distribution device (10) has a conductive housing (20) for forming a shield, and has at least one conductor track mount (26, 28), which is arranged in the housing (20), for connection of the various line and/or connecting devices (12). According to the invention, the shielding devices (18) can be conductively connected via the conductor track mount (26, 28) to at least one contact element (40, 42) which can be attached to said mount, and the housing has conductive housing parts (36, 38), wherein at least one of the housing parts (36, 38) has at least one structure (46, 48) with at least one elastic contact projection (50, 52) for making electrical contact with the attached contact element (40, 42), and another of the housing parts (38, 36) has at least one clamping device (56, 54) with two clamping jaws (58, 60) for clamping the contact projection (50, 52) to the attached contact element (40, 42) when the housing parts (36, 38) are joined together. The invention furthermore relates to a method for fitting a corresponding electrical distribution device (10).

Cable terminal- or connection device, preferably for multiple-core cable, has cable terminal module or the first cable connection module provided with a splice part having a bushing entrance

Abstract: The cable terminal or connection device includes a splice part (4) which has at least one radially external conductor guide slot (16) with the stripped end of the cable core (7) taken through the bushing entrance (5). The clamping- and connection unit (9) has at least one clamping spring on the cable side and in the assembled state of the cable connection module, the clamping spring functions in conjunction with the stripped end of the cable core (7), such that the clamping spring electrically contacts the stripped end of the core.
