Portable drive unit for valve actuator

Abstract: A portable drive unit for a valve actuator includes a portable two-cycle or four-cycle gasoline engine and a gear reducer. The gasoline engine is bolted, through vibration damper means, to the housing or gear box of the gear reducer. The gear box is clamped to the valve actuator through an annular clamp and clamp-receiving adapter structure which also includes vibration damper means. A flexible sleeve coupling in the bore of the annular clamp and clamp-receiving adapter couples the output shaft of the gear reducer to the handwheel input shaft of the valve actuator.

Eddy current speed reducers

Abstract: It is an eddy current speed reducer whose stator comprises a ring of coils 2 having their axes parallel to the axes of the speed reducer and whose rotor comprises two discs 3 framing the stator. The support for the coils is formed by a non-magnetic closed annular housing 9 containing the windings 6 of these coils and formed from two half-shells clamped axially one against the other by screwing flared pole pieces 7 on the cores 5 of the coils, these cores passing jointingly through openings 11 in the housing. A preferred application is to speed reducers developing relatively low braking torques.

Abstract: The insufflation on apparatus is for free-flowing media, particularly carbon dioxide gas, into human or animal bodies, having a intermediate receiver connected to a supply of gas under pressure via a pressure reducer. The gas passes from the receiver via a second pressure reducer and a first branch pipe with a throttle limiting flow to 11/min at maximum pressure, and also via a second branch pipe with a bypass valve allowing the flow to be increased many times, at a pressure limited to tht of the venous abdominal pressure, to an insufflation instrument. The bypass valve (26) has an actuator (30) opening and shutting it automatically, and operated by a switch or pushbutton (34). The actuator also has a preselector switch (32), by which the desired quantity of the gas can be set.

Controlled start speed reducer

Abstract: A controlled start speed reducer in which input and output shafts are axially aligned with one another in an outer housing and an inner housing is journaled in the outer housing coaxially with said shafts.

Device for detecting chip damage of milling cutter

Abstract: PURPOSE:To detect chip damage easily and positively by adopting a vibration detector which picks up abnormal vibration produced when some chips on a milling cutter are damaged during operation. CONSTITUTION:A vibration detector 9 mounted on a main spindle head of a motor 2 detects abnomal vibration due to damaged chips on a milling cutter B.

Output from the reducer is transfered to a comparator 14, and is transfered to an abnormal discriminating gate 17 if abnormality exists.

Epicyclic cog belt speed reducer

Abstract: In mechanical apparatus for reducing angular speed, commonly known as speed reducers, its is known as a planetary type reducer with a very high reduction ratio; in the order of 1000:1 and higher, It has concentric input and output shafts, on each of which is fixed a sun cogwheel; there is a third sun cogwheel, also on the main axis, which is fixed to the frame. Each sun cogwheel is connected to a planet cogwheel with a cog belt to form a planetary set, The three planet cogwheels are fast on a common shaft which rotates about its own axis and also about the axis of the input and output shafts; as the planets spin, they are drawn about their respective suns and the teeth on the planet wheels describe an epicyclic path, The speed reduction ratio is dependent mainly on the difference in the relative sizes of the output sun wheel and the sun wheel fixed to the main frame; when there is zero difference the reduction ratio is infinite, Chains and sprocket wheels can be used in place of cog belts and cogwheels in applications where maximum output torque is required.

Long pipe material for continuous stretch reducer

Abstract: PURPOSE:To obtain a steel pipe material for a stretch reducer prevented from breaking at and near a welded part by giving a proper balance between strengthes of a mother pipe and a joint. CONSTITUTION:For the continuous manufacturing of a small-diameter pipe by a stretch reducer, the strength rate of a welded joint part to a mother material part in a high temperature of 800-900 degrees C in a pipe material previously prolonged by welding is taken in 1.00-1.30. Material A steel is given by connecting carbon steel pipes by friction pressure welding, and is processed by stretch reducing after external beads are cut off. In this case, since the mother pipe and the joint part are given an essentially equal quality, the strength of the pipe joint is almost equal to that of the mother pipe in a high temperature of 800-900 degrees C.
