Title: Improvements in or relating to apparatus for feeding articles to machines
IPC: B08B9/44
Filed: 1945-08-09
Abstract: 603,174. Endless-belt conveyers. LUNN, F. M., UNITED DAIRIES (LONDON), Ltd., and U.D. ENGINEERING CO., Ltd. Aug. 9, 1945, No. 20454. [Class 78 (i)] In means for feeding articles to a machine, e.g. bottles to a washing machine, a series of articles is transferred from an endless-belt feeding conveyer to shoots leading to the machine by a rotary bar moving transversely to the conveyer, the arrangement being such that the conveyer drive is interrupted momentarily when the articles are engaged by the bar. A bar 31, Fig. 1, disposed longitudinally of the conveyer 10 is carried by arms 30 fixed on a shaft 29. This shaft is driven by chain- and sprocket gearing from a gear 26 fast on a parallel shaft 11. A ratchet wheel 19 fast on the shaft 11 is engaged by a pawl 21 pivoted on the face of a gear 12 which is free on the shaft. The gear 12 is connected by toothed and bevel gearing to the driving shaft 17 of the conveyer. The pawl projects beyond the ratchet wheel sufficiently far to be engaged by a nose-piece 23 on a lever 24 pivoted to the framework at 25 when this lever is depressed by a projection 32 carried by the shaft 29 coming into contact with a curved abutment 33 on it. This engagement occurs at the time of engagement of the bar with the articles, and since the movement of the lever disengages the pawl from the ratchet, the conveyer drive is interrupted until the projection leaves the abutment and the pawl is returned by the spring 22. Bottles may be brought from a loading station to the conveyer 10 in an erect position on an endless belt 37. They are pushed from this belt through a curved guide 36 consisting of wires 39 and are deposited on their sides between cross-members 34 on the belt 10.

Abstract: 1,166,238. Change-speed control. INTERNATIONAL HARVESTER CO. 1 Nov., 1966 [6 Jan., 1966], No. 20501/69. Divided out of 1,165,013. Heading F2D. An hydraulic control system for the supply of cooling and lubricating liquid to the friction members and bearings of the range shift clutches of a vehicle transmission includes a selector valve which, in its neutral setting, admits low pressure liquid to all the clutches and bearings, and which, when moved to an engaged setting, admits high pressure liquid to engage the selected clutch and maintainthelowpressure supply to the remaining clutches and bearings, and also includes a unidirectional valve associated with the selector valve. As shown for an arrangement including range shift and reverse clutches 122 with their associated bearings 124, liquid is supplied to the actuators 12, 16 by a pump 98 through the selector valve 10 with which are associated high and low pressure relief valves 94, 102, the one-way valve 118, and a restriction R in the supply line to the individual clutches and bearings. In the neutral setting shown valve 94 is by-passed, the liquid passing from selector valve 10 through the one-way valve 118, the restriction R causing a pressure build up to the point at which relief valve 102 opens. On moving the selector valve to the F1 setting, for example, high pressure liquid is fed to the forward actuator 12 which, when filled, causes increased flow through restriction R and a pressure build up through selector valve 10, high pressure junction 92 to relief valve 94 which operates to maintain the desired high pressure in the engaged clutch. The lower pressure junction 100 is maintained at the original low pressure by valve 102, the supply of the low pressure liquid being continued through ports F2, R1 to the inoperative clutches while the valve 118 remains closed to prevent loss of pressure through the open port 114 of the selector valve.

Abstract: 460,872. Re - recording sound - films. TOBIS TONBILD - SYNDIKAT AKT.- GES. July 24, 1936, No. 20521. Convention date, July 30, 1935. [Class 40 (ii)] Noiseless sound-film records are produced by first recording with transparent marking on an opaque film, re-recording from this primary film, and combining with the new record a modulation of the primary record obtained by scanning. The primary is made by recording the half waves as transparent areas on a dark background by means of a microphone 1 and a split-wave recording device 2. This is re-recorded by balanced cells 4, 5 on the film 6 and, in addition, a modulation band 8 is formed by a further cell 7 scanning the full width of the primary and having the current impulses smoothed. The cell 7 may be extended in the direction of the sound track so that its output may vary with the loudness of the recorded sounds and the currents from the cells 4, 5, and 7 may be superimposed in one recording device. The currents from the sound-scanning cells may be tapped and rectified to produce the noiseless control.

Title: Improvements in the manufacture of spongey rubber or similar material
IPC: C08L21/00
Filed: 1931-07-20
Abstract: Into latex or other dispersion is mixed a small quantity of rubber solvent (petrol, naphtha, carbon tetrachloride) whereby the nerve of the rubber is broken down, vapour bubbles are formed, and the dispersion is set.  The mixture is preferably beaten to a stiff cream before it is poured into moulds.  By raising the fresh mixture nearly to the boiling-point of the solvent a very light resilient reticulated mass is obtained, but it is stated that expansion due to bubble formation occurs even when setting takes place at ordinary temperatures.  The dispersion may be concentrated and compounded; may be reinforced with fibres; may be of reclaimed rubber, artificial rubber, guttapercha, balata; and may be pre-vulcanized.  In examples, 5 parts of petrol are mixed with latex mixes containing 91 parts of rubber in the form of 70 per cent latex.  The resulting spongy mass is vulcanized in hot air.  Fabrics or strings may be stretched in the moulds, or bars which may afterwards be withdrawn.  Instead of moulding the mixture it may be picked up on shaped formers, or it may be deposited on a fabric web which may be folded into layers to serve as an upholstering material, or the fabric may be stripped away before the material is folded.

Abstract: 585,032. Fluid-pressure servomotors. ELDRED, R. J.; WALKER, G. W. HIGGS-, and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Dec. 10, 1943, No. 20740. [Class 135] A speed governor for an internal combustion turbine comprises a pump driven by the turbine and supplying fuel through main control valve openings 2 to the atomisers and pressures on each side of the openings 2 are applied to each side of a spring-loaded piston 10 that controls the by-pass openings 3 to allow excess fuel to return to the suction of the fuel pump. When the speed of the turbine falls, the pressure difference across the openings 2 is reduced and the piston 10 moves to close the by-pass openings 3 and opens a port 14 whereby fuel passing through the throttle 14a builds up pressure in the space 15 and causes the cylinder 12 to follow the movement of the piston so that a constant pressure difference is maintained across the openings 2 and the speed is maintained constant for varying load condi-. tions on the turbine. The speed at which the cylinder 12 follows the piston 10 is determined by the adjustment of the throttle .19. The speed at which the turbine is to be controlled is adjusted by varying the openings 2 by a lever 1 connected to a control valve 4. To raise the speed, the control valve is moved to the right and pressure difference across the piston 7 causes it to move to enlarge the openings 2. The rate of movement is controlled by the throttle 9 and the fuel displaced by the piston passes to the atomisers and assists the acceleration required. The governor may be used with.the starting valve described in Specification 585,029, [Group XXVI], controlling acceleration up to idling speed.

Abstract: 1472874 Determining firing angle of an IC engine SIEMENS AG 10 May 1974 [10 May 1973] 20883/74 Heading G1N [Also in Division G4] To measure the firing angle in an internal combustion engine, pulse trains are derived by gating pulses from an oscillator in response to sensed marks on a rotary part in the engine, the train x representing the time between a reference point and the instant of ignition and the train y the time between two points defining a reference angle. The pulse train y is fed to a scaler counter which performs a division by a constant r, the output of this counter being fed to a divisor counter. The contents of the two counters are repeatedly added into respective accumulating sum stores, the contents of the sum store associated with the divisor counter being compared with the contents of a counter supplied with the pulse train x and the carry output of the other sum store being supplied as an input in the least significant digit position of the divisor sum store. The contents of the result counter give the firing angle relative to the first mark on the engine. To produce the absolute firing angle relative to top dead centre of the engine the result counter is initially loaded with a value equal to the angle by which the first mark leads top dead centre, the counter being decremented to zero and then incremented, its final contents being the absolute firing angle relative to top dead centre.
