Title: Improvements in and relating to clutches
Inventor: MEYER GUSTAV
IPC: F16D48/02
Filed: 1960-08-25
Abstract: 906,261. Clutch control. MAYBACH MOTORENBAU G.m.b.H. Aug. 25, 1960, No. 29451/60. Class 80 (2). A multi-disc friction clutch is provided with light-engagement springs 22, full engagement being effected by pressure liquid supplied by an engine-driven pump 28 through limbs 30, 31 to a moving power cylinder 20 under the control of a piston valve 33. The arrangement shown comprises a clutch release pedal 40 and accelerator pedal 37, and with the pressure liquid supply ineffective, the clutch may be disengaged against the force of springs 22 by pedal 40 operating a lever 46 engaging a sleeve on the clutch pressure plate 19 through hydraulic pistons 41, 45. Under these conditions a spring- loaded piston 51 in a cylinder 50 connected by a line 49 to control valve 33 positions a bell crank lever 54 carrying an adjustable stop pin 55 in such a position as to limit the opening of the throttle valve 39, when operated by pedal 37, to an extent appropriate to the torque capacity of springs 22. With valve 33 in the position shown and pump 28 effective, pressure liquid is supplied through line 30 to cylinder 20 to the left of a fixed piston 21 to fully engage the clutch, and also to cylinder 50 to retract piston 51 and allow full opening of throttle valve 39. Upon depressing pedal 40 valve 33 is moved to the right so that pressure liquid is supplied through line 31 to the right-hand side of piston 21 to disengage the clutch, and at the same time line 49 is cut off so that piston 51 moves downward to prevent full opening of throttle valve 39.

Title: Improvements in and relating to processes of sifting pasty materials particularly cement pastes, treated in a wet state
IPC: B28C1/08
Filed: 1931-10-26
Abstract: A process of sifting pulverulent material, particularly cement pastes, in a wet state consists in throwing the mixture of paste and water against a sieve.  The apparatus may consist of a series of superimposed sieves which are adjustable so that the height of fall from one sieve to the next may be varied according to the viscosity of the mixture being treated.  Alternatively a conduit with apertures in the bottom may be arranged above a horizontal or inclined sieve or mechanical devices may be used for directing jets of the material against a sieve.

Title: Improvements in or relating to selective receiving circuits for signal transmission systems
IPC: H03H7/075
Filed: 1923-11-24
Abstract: 207,552. Siemens & Halske Akt.-Ges. Nov. 25, 1922, [Convention date]. Filter, rejector, and separator circuits. - A selective system of impedance networks, for separating out currents of a given frequency from a complex of currents is so designed as to prevent the transient or shock effects of any sudden change in the input energy from affecting the receivers. It is stated that the natural oscillations which constitute the " equalization process " are always situated within the permeability range of the screening networks, and that their distribution is dependent upon the load at the end of the chain. A mathematical analysis is given of the circuit conditions when the end of the chain is (a) short-circuited, (b) open-circuited, (c) closed by a definite resistance, and (d) closed by the " wave resistance" As applied to a wireless or multiplex telephony set, several screening chains are connected in series in front of the receiver, having a progressively decreasing range of permeability. Each unit is so chosen that the range of frequency of the " equalisation process " in one chain is situated outside the range of permeability of the next following chain so that the transient effects are gradually choked or eliminated. As shown in Fig. 6 the limit frequencies of the chain b are 100,000 and 120,000. The high-frequency amplifier and rectifier c next in series has an input resistance approximately equal to the " wave resistance " of the chain C. The heterodyne frequency (from a local oscillator not shown) is 7450 and the screening series d have limit frequencies of 7000 and. 8000. The low-frequency amplifier e is coupled under the same conditions as the amplifier c, and is followed by a screening chain f having limit frequencies of 7300 and 7600, which, in turn, feed the receiver g. Fig. 7 shows a screening chain h closed by a resistance r' followed by a second screening chain i closed by the receiver k.

Abstract: 713,160. Turbine or compressor blades. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Nov. 27, 1952 [Dec. 20, 1951], No. 30075/52. Class 110(3) [Also in Group XXXVI] A blade for an elastic fluid turbine or compressor is formed by applying a metallic shell to a preformed cone assembly made at least in part of synthetic resinous material so as to completely enclose it. The compressor blades 12, Fig. 1 shown comprise a core 14 made of synthetic resinous material enclosed by a metallic shell 15. The core is formed of a moulded synthetic resinous material which is coated with silver and then placed in an electrolytic plating bath where high. strength nickel or copper is deposited until a thickness of 0.02 to 0.04 inches is obtained. The wall thickness may be tapered by slowly withdrawing the blades, tip uppermost, from the bath.

Filed: 1926-11-29
Abstract: 278,211. Marks, E. C. R., (U. S. Industrial Alcohol Co.). Nov. 29, 1926. Alccholic liquids, distilling.-Weak alcoholic liquids, such as beer, are distilled to separate strong alcohol, fuel oil, and light-boiling products such as aldehydes. The beer preheated by passage through a dephlegmator 2 or by heat exchange with the residual liquid passing through a pipe 6 is passed by a pipe 3 into a rectifying column 4. heated by a steam coil or by injection of steam at the base 7. The vapours pass from the top by by a pipe 5 through the dephlegmator 2 and a condenser 13. The condensate from the dephlegmator and part of that from the condenser pass by pipes 11, 19 to serve as reflux in the column. The remainder of the condensate together with uncondensed vapours passes by pipes 20, 23, 25 into a second rectifying column 24 heated by a steam coil 29, from the base of which purified alcohol is withdrawn. The light boiling vapours from the top of this column pass through a dephlegmator 31 and condenser 36, part of the condensate being returned as reflux to the column and the remainder being drawn off by a pipe 42. The temperature in the column 4 is regulated so that a thermometer 8 at a point just above the inlet 3 reads about 85‹ C. by varying the amount of condensate admitted to it through the pipe 19 either by varying the rate of passage of cooling water through the condenser 13 or by varying the amount drawn off by the pipe 20 through a cock 21. Fusel oil is drawn off by a pipe 9.

Strainer separators.-Apparatus for the continuous extraction of juice from grapes, or for like purposes, has a rapidly rotating strainer 1 containing a screw 10 rotating at a different speed from that of the strainer, and which projects the residue of the material against the casing wall 25. The strainer is carried by supports 2 rigidly secured to the shaft 3 which is rotated through friction gearing 5, 4 from the motor shaft 6. The screw 10 is driven from the shaft 6 through belts 16, 18, bevel gearing 20, 21, worm gearing 15, 14, and toothed gearing, the last wheel of which is the wheel 11 on the structure carrying the worm.

The material to be treated is fed into the hopper 9, passed to the entrance of the strainer 1 and carried by the screw 10 slowly to .the bottom of the strainer. The extracted juice passes through the strainer and is collected by the gutter 23 from which it is taken by a coilduit. The residue of the material is thrown violently between the supports 2 to the wall 25, from which it falls to the plate 26 and is led by a guide plate to the outside of the machine ready for passage through a second machine or another passage through the same machine.
