Title: Improvements in machines for pressing plastic material
IPC: C11D13/18
Filed: 1928-12-17
Abstract: 326,796. Jones, R. A. Dec. 17, 1928. Rotary-mould-table machines; feeding; delivery; strain, preventing.-In soap-presses of the type described in Specification 15417/14, the blanks are fed towards the rotary mould carried by a conveyer and are lifted into alignment with the moulds by a reciprocating pusher, a horizontal pusher transferring the article into the aligned mould. As shown, soap blanks 12 are advanced by a pair of belts 13, Fig. 7, into range of lifters 32 which raise the end pair into alignment with pushers 75 carried by a slide 69. The pushers transfer the blanks to moulds 63 in a carrier 61 mounted upon a shaft 62 which is rotated intermittingly from a shaft 57 through a Maltese Cross gear 64, 66. A stop plate 76 limits the movement of the blanks through the moulds. After a quarter revolution of the carrier, the blanks are aligned with opposed pairs of pressing plungers 98, 103, Fig. 1, carried by slides 94. 100 which are reciprocated simul. taneously by links 91, 96 connected to the opposite ends of toggle levers 89 actuated through a link 48 by a crank pin 48<a> on a flywheel 49 carried' by the main shaft 50. The toggle is caused to pass dead centre to effect a double compression. A pin 90 on the toggle 89 actuates the slide 69 through a link 83 and lever 80. The plungers 103 are resiliently supported by springs 109 to accommodate themselves individually to the soap blanks. After a further quarter revolution, the pressed cakes are discharged by pushers 112, Fig. 7, carried by the slide 69, into a channel 113 and are discharged laterally by an arm 118 carried by a slide 119 reciprocating along guides 121, 122. The shaft 57 is driven from the main shaft 50 through spiral gears 60, 53 and drives through gears 56, 55 a shaft 53 carrying at one end a crank disc 52 actuating the slide 33 of the lifters 32 and at the other a crank disc 133 the pin 132 of which engages a slotted lever 131 mounted upon a rock-shaft, carrying a lever .connected to the slide 119 by a link 125. Intermittent movement is imparted tc the belts 13, Fig. 1, through ratchet mechanism 40, 39 actuated from the pin 48<a> through links 46, 43 and a lever 44.

Title: Improvements in or relating to a centrifugal governor
IPC: G05D13/00
Filed: 1955-12-30
Abstract: 794,851. Governors. SUNDSTRAND MACHINE TOOL CO. Dec. 30, 1955 [March 16, 1955], No. 37408/55. Class 57. [Also in Group XXIX] A centrifugal governor has pivoted flyweights 36 controlling the position of a slidable control valve 37 which is loaded by a main spring 50 and by an auxiliary spring 58, the latter spring being weaker than the main spring but acting, in the event of failure of the governor drive, to move the valve beyond the position which it occupies at slow speeds so that the governor " fails safe." The auxiliary spring is fitted between two telescoping members 56, 57 and the main spring extends between a seat 55 on the member 56 and an adjustable seat 51. The valve 37 slides within a rotatable ported sleeve 33 and a fixed ported sleeve 32 encircles the sleeve 33. The governor controls the supply of pressure fluid from a pipe 31 to one or other side of a compound piston 22 and sets the position of the wobbler 15 of a variable volume piston pump fitted in an hydraulic transmission connecting an aircraft engine with an alternating current generator. Under starting conditions both springs 50 and 58 are extended, as shown in Fig. 3, and fluid pressure is directed to a pipe 26 through passages 59, 59a, groove 42a and port 40, thus moving the piston 22 to the left and setting the wobbler 15 at full underdrive position. When the engine has speeded up to about 1800 r.p.m., the flyweights have moved the valve 37 sufficiently to the right to direct fluid pressure through the port 41 and the pipe 28 to the left-hand side of the piston and the wobbler is moved to full overdrive position. This condition obtains until about 2400 r.p.m., when the auxiliary spring is fully compressed, the members 56, 57 are fully telescoped and the normal governing operation by the ports 40, 41 is controlled by the flyweights 36 and the main spring 50 to provide a constant transmission output speed. In the event of failure of the governor, the auxiliary spring moves the control valve beyond the position calling for full overdrive (the position to which it would otherwise be moved by the main spring) and the wobbler returns to the starting or full underdrive position. During the normal governing operation, the pressure existing in both pipes 26, 28 closes a pair of pressure-responsive switches A and B series-connected in the circuit of a solenoid which closes a switch cutting the generator into the electrical system; at speeds below 2400 r.p.m., one or other pipe 26, 28 is connected to drain and one or other switch A, B opens so that the generator is cut out of the electrical system.

In a method of making bushes of synthetic plastics material, a thin foil of said material is formed around an outer bearing surface of an inner machine element. The thin foil 6, Fig. 5, has cut-outs for keys &c. and lubricant recesses 61 therein. The bushes, which may be made of nylon, for example, are interposed between sliding metal pulley-flanges of a rectilinear bearing for an expanding pulley. In an embodiment employing said bushes, a variable-speed vee-belt transmission assembly comprises a resilient pulley A and a control pulley B interconnected by a belt 14. The speed is varied by increasing and decreasing the effective diameters of pulleys A, B which have coaxial portions 2, 7, Fig. 1, and 32, 37, Fig. 2, respectively. The portions 2, 7 have coaxial hubs 4, 8 separated by the nylon &c. bush 11 and a similar bush 3 is positioned between the hub 4 and a shaft 1. Relative rotation between the shaft 1 and hub 4 and between hubs 4 and 8 is prevented by keys 5, 10, Fig. 3. The hubs 4, 8 are recessed at 19, 20, Fig. 1, to receive a lever 16, pivoted at 17 and positioned to transmit equal longitudinal movements to pulley portions 2, 7. The portions 2, 7 are urged towards the belt 14 by a spring 12 housed in an abutment member 13 attached to the hub 4. Similarly, the portions 32, 37 of the pulley B have coaxial hubs 34, 38, the former of which is mounted on a shaft 31, and nylon &c. bushes 41, 36 are mounted therebetween. A lever 46, pivoted at 47, transmits equal longitudinal movements of the portions 32, 37 which are urged by a spring 42 in a housing 44, the latter being attached by screws 44a to the portion 37. Additionally the pulley B can be adjusted manually by a wheel 48, which is keyed to a screw-threaded spindle 53, housed in a screwthreaded bush 58 which is supported and prevented from rotating by a member 57 having a key 56 therein. The spindle 53 is mounted in a ball bearing 60 carried by the portion 32 and the bush 58 is in ball bearing 59 carried by the portion 37 so that as the handle 48 is rotated, the portions 32, 37 move nearer together or farther apart. As this manual adjustment of pulley B takes place, the pulley A is automatically adjusted by the spring 12, the distance between the pulleys being fixed.

Abstract: 914,883. Pulse code-modulation systems. STANDARD TELEPHONES & CABLES Ltd. Sept. 29, 1961 [Nov. 16, 1960], No. 39385/60. Drawings to Specification. Class 40 (5). In a pulse code-modulation system an input signal waveform is split into two or more phase-displaced components of similar power spectra, the phase-displaced components being individually sampled, coded and transmitted by pulse modulation means, and the transmitted signals on reception being separately decoded to yield correspondingly phase-displaced components which are recombined into an approximation of the original signal waveform. In the embodiment described, the input signal is split into two phase-displaced components which are arranged to be approximately in quadrature over the frequency range used in telephony. After quantization the information contained in the two waveforms is largely independent. It is stated that after re-combination of the phase-displaced waves at the receiver in phase-shift networks complementary to those used at the transmitter certain of the noise-producing harmonics introduced during quantizing are cancelled. Each of the phasedisplaced waves may be sampled at half the normal rate (twice the highest signal frequency component) or improved quality over the conventional method may be obtained if this sampling rate is increased up to the normal rate. The arrangement may be used in conjunction with known compression and preemphasis methods or where a small number of quantizing levels are used a further channel may be added sending a volume control signal at a syllabic rate. The two phase-displaced components are arranged to share the same channel in time division. In a high quality system the two channels may be used independently at peak traffic periods with some sacrifice of quality.
