Title: Mechanism for the winding of threads, especially of covered rubber threads
IPC: B65H54/42
Filed: 1961-03-10
Abstract: 918,717. Winding apparatus. MAYER TEXTILMASCHINENFABRIK G.m.b.H., KARL. March 10, 1961 [March 12, 1960], No. 8907/61. Class 120 (2). A mechanism for winding thread, especially covered rubber thread, in the form of a cylindrical cross spool, has a spool that is driven directly by a drum which is spring-influenced for axial movement in one direction, the extent of this movement being controlled by engagement of the drum with a conical end surface of the spool. In Fig. 1 a slotted drum 6 is biased by a spring 9 against the conical foot 2 of a spool 1. As the drum 6 rotates it turns the spool 1 and causes a slider 11, moving in slots 10 in the drum, to cross-wind thread on to the spool 1. As the diameter of the package increases the spool 1 is forced away from the drum 6 and the drum then moves to the left until it is again in contact with the conical foot 2. The result is a cross-wound package having a build at both ends that corresponds to the shape of the foot 2. In Fig. 4 a drum 19 turns the spool, the drum 19 being biased to the left against the conical foot of the spool. A reciprocating shaft 7a carries a retainer 23 on which is mounted an elongated eye 20 frictionally secured by a screw 22 to the retainer 23. Due to the reciprocating movement of the shaft 7a the eye 20 traverses the thread on to the spool. As the package increases in diameter the thread moves up the slot eye and thus creates an increasing turning moment that alters the inclination of the frictionally held needle 21, the initial tension of the thread being adjusted to ensure that the conical build-up of the ends of the package conforms to the shape of the coned end of the bobbin. As the package increases in diameter the spool axis moves away from the drum 19 and the drum 19 is then biased to the left until it is again in contact with the conical foot of the spool.

Title: Improved method of equalising pairs of self-induction coils for loading pupinised four-wire telephone lines
IPC: H01F17/08
Filed: 1922-03-28
Abstract: 187,938. Felten & Guilleaume Carlswerh Akt.-Ges. Oct. 22, 1921, [Convention date]. Inductances. - Relates to inductance coils, used for loading two main circuits and a phantom circuit, in which two pairs of coils are wound on cores 1, 2 placed on opposite sides of an iron disc Z to which the coree are connected by iron bridge-pieces S, the whole being enclosed in a protective laminated iron frame R. According to the invention the self-inductance of the two pairs of coils when acting as duplex loading coils in the phantom circuit, is equalized without interfering with the self -inductance of the pairs of coils in the main circuits, by moving the coils nearer to one of the longitudinal sides of the frame R, thereby varying the relative self-inductances by varying the magnetic resistance of the leakage fields between the poles of the coils and the frame. Specification 157,316 is referred to.

Title: Improvements in and relating to two-stage steam-operated ejectors
IPC: F04F5/46
Filed: 1921-03-23
Abstract: 160,786. Maschinenfabrik Oerlikon. March 26, 1920, [Convention date]. Aspirating apparatus ejector. -In a twostage steam jet apparatus for exhausting air or other gases from a vacuum chamber into the atmosphere, part of the steam from the inlet pipe 1 flows through a central nozzle 4 and discharges the gases from a chamber 8 communicating with inlet 7 of the vacuum chamber, the mixed gases passing through a compression tube 9. This discharge is accelerated by the greater volume of steam which passes from the cone 3 through passages 5 into by-pass tubes 6 surrounding the tube 9. The end combining cone 10 communicates by a delivery cone 11 with the atmosphere. In order to increase the surface of contact of steam and air in the chamber 8, the nozzle 4 is preferably subdivided by two or more ribs so that the air may enter the interior of the steam jet through slots left by the ribs at the outlet end of the nozzle.

Title: Improvements in and relating to distributing valve mechanisms for devices having pistons operated by compressed air
IPC: B25D9/16
Filed: 1952-04-10
Abstract: 728,829. Engine distributing valves; valve gear. BOHLER & CO., AKT.-GES., GEB. April 10, 1952 [April 11, 1951], No. 9197/52. Class 122 (2). In a distributing valve mechanism for devices having pistons operated by compressed air, particularly impact tools, in which two annular valve a, b slide one within the other the compressed air is supplied during the working stroke of the piston through two annular gaps and during the return stroke through only one annular gap. The valve a has a cylindrical part c which is slidable within a cylindrical part d of the valve b and controls a port g therein. During the working stroke as shown in Fig. 1 the valves are slid into each other as closely as possible, the valve a bearing on a seat s and compressed air flows between the valve a and a seat m and between the valve b and a seat n to the cylinder space above the piston to force the latter downwards; air below the piston being exhausted to atmosphere through a passage e, annular groove f, port g, and annular groove h. Towards the end of its working stroke the piston first uncovers a port communicating with a passage p leading via passages q, r to cavities i, k in the internal end surfaces of the valves a, b, and then immediately after uncovers its exhaust port. Since the passage p is of relatively small diameter the - pressure of the air acting on the valves a, b to press them together falls before that in the cavities i, k and the valves a, b are thereby forced apart so that valve a bears on seat m and valve b on seat n and port g is closed. Compressed air then flows between valve a and seat s and through passage e to the cylinder space below the piston to urge the latter upward on its return stroke. When the air above the piston is sufficiently compressed it causes the valves to slide into each other again and the cycle recommences.

Filed: 1937-04-01
Abstract: 484,945. Refrigerating. MAIURI, G. April 1, 1937, No. 9288. [Class 29] Absorption systems.-In an apparatus of the type described in Specification 391,378, the evaporator for the liquid refrigerant readily drains and is located at a higher level than the portions of the apparatus in which absorption liquor circulates. Refrigerant is vaporized from absorption solution into an inert gas in vessel c and the mixture is led through pipe d to a condenser e cooled by solid carbon dioxide in chamber b. Liquefied refrigerant flows through pipe g to evaporator h which may be packed with wire gauze. The evaporated refrigerant passes through pipe r to vessel n and the force of flow of the vapour causes absorption liquor to circulate from vessel n to vessel p and through heat exchanger to vessel c. The return flow takes place through exchanger j and vessel l to vessel n. The compartment a is thus cooled by the evaporation in vessels c and h.
