Abstract: 1,134,524. Valves. ROBERTSHAW CONTROLS CO. 28 Feb., 1966 [4 March, 1965], No. 8732/66. Heading F2V. [Also in Division A4] A programmed pneumatic control system, particularly for a dish-washing machine, comprises a timer motor for moving a programme member at a constant rate to effect a timed sequence of operations, and a pair of over-riding actuators for moving the programme member at a rate faster than said constant rate to eliminate certain operations of the sequence, the actuators acting upon the programme member in alternation. In the illustrated system the programme member comprises a flexible sheet 119, Fig. 4, provided with recesses 125 and apertures 126 and secured to a rotary member 117 having a ring gear 121 by which it is rotatable by a pinion 122 on a shaft 123 connected by a one-way clutch to the output shaft of a timer motor 112. The sheet 119 is mounted adjacent a plate 35 provided with apertures 19 to 34 shown diagrammatically in Fig. 1, and various combinations of which are interconnected by the recesses 125 as the sheet 119 rotates to control the dishwashing programme. The plate 35 is also provided with apertures 47 to 54, pairs of which may be interconnected by recesses 133 in a member 127 which is rotatable to various positions D, N, H, S, P, and C, to select the programme steps to be performed. In the H position of the selector member 127 none of the apertures 47 to 54 are interconnected and a heavy washing programme is performed. The programme is started by closing a switch to energize a vacuum pump 43 and the timer motor 112. The programme sheet 119 thus rotates so that in sequence (a) the parts 28, 30 are interconnected to apply suction to an actuator 88 to open the water inlet valve 92 for an interval terminated when the port 30 is connected to atmosphere through an aperture 126, (b) the ports 32, 34 are interconnected whereby an actuator 101 closes a switch 13, 14, 15 to energize the dishwasher impeller motor 11 for a first rinsing period, (c) the ports 26, 28 are interconnected so that an actuator 16 operates a switch 12 to cause the motor 11 to operate a drain pump, and (d) by further interconnections of selected ports effecting washing with detergent, draining, and rinsing a plurality of times, followed by draining and drying steps. If, however, the selector 127 is set in the N or D position to effect normal washing (when parts of the washing periods of the heavy washing programme are omitted), or drying, vacuum is applied to ports 24 or 23. The rotating programme sheet 119 then alternately interconnects the ports 23, 24 to ports 20, 21 while alternately interconnecting the ports 20, 21 to atmosphere to operate actuators 62, 63 alternately to rapidly advance the programme member 116 by pawl-and-pinion devices 140, 124 (Fig. 5, not shown).

IPC: F41J7/04
Filed: 1917-06-19
Abstract: 109,248. Quack, C. M. A. Aug. 29, 1916, [Convention date]. Addition to 102,144. Targets.-To prevent the target from being released by a gust of wind, a screen to be pierced by the bullet is provided, through which the silhouette can be seen, and which is worked against wind pressure but falls forward with the struck target. The rocking beam 29 carrying the wind-screen is on the same axis 4 as the target and carries by means of a pivot 30 a gravity latch 36 which normally, by means of a curvednotch 34, engages a pin 37 between ears on the cross-stay 27, which is notched from below to accommodate the catch. A gust of wind does not shake this latch free, but on the target tipping forward, a lever 38 on its beam turns the latch clear of the pin 37, and the wind-carrier tips also, lugs 39, 40 on the two beams coming into contact. Owing to these lugs, when the target is righted, the wind-screen is also righted, and the latch re-engages, the lug 40 parting slightly from the lug 39. A screw 44 feeding into the notch 34 varies the available depth of the notch. A peg 31 supports the latch from below, and a stop 33 prevents an excessive swing. The latch is provided with an eye 32 adapted to receive a pin for setting the latch out of action on a windless day.

[Class 108 (iii).] An aircraft shock strut includes liquid damping means for absorbing the initial shock, means for resiliently supporting the load after the initial shock and means for exerting a' differential damping action on the resilient support. In the construction shown in the Figure the tube 40 as it telescopes within the tube 10 forces oil through an orifice 46 in a piston 44 on the tube 40, to absorb the initial shock. The piston 44 ultimately bears upon the diaphragm 24 which is provided with throttling orifices 26 and is supported by the spring 22. Movement of the spring 22 and the parts supported thereby is further damped differentially by a piston 30 on a rod 28 connected to the diaphragm. The piston 24 is movable in a small cylinder 20, leakage therefrom being provided by orifices 32 and annular clearance around the rod 28. Non-return valves 36 are provided on the piston 30. In modifications, the one-way damping effect is obtained by throttling orifices communicating with the annular chamber formed by the difference in diameter between the tubes 10, 40.

Filed: 1946-03-26
Abstract: 617,091. Valve generating circuits. BABAT, G. I. March 26, 1946, No. 9268. [Class 40 (vi)] A polyphase thermionic valve oscillator comprising a number of anode oscillatory circuits with star-connected inductances and polygonconnected capacitances, has a common shortcircuited shield surrounding all the inductances. Fig. 1 shows the circuit connections of a threephase generator, and in accordance with the invention a shield (not shown) is arranged to surround star-connected coils 4, 5 and 6 which, together with condensers 7, 8 and 9, form the anode oscillatory circuits of valves 1, 2 and 3. This shield, by increasing the mutual inductance between coils 4, 5 and 6, reduces the tendency for parasitic oscillations, which might otherwise occur due to valves 1, 2 and 3 operating in parallel. The tendency for parasitic oscillations is further reduced by including grid stopper resistances 25, 26, 27 and by making the value of capacitors 7, 8 and 9 considerably greater than the stray and inter-electrode capacities which form part of the parallel connection oscillatory circuit.

Filed: 1928-03-28
Abstract: 302,717. Balachowsky, D., Caire, P., and Levy, M. Dec. 21, 1927, [Convention date]. Vaporizers, external.-A combustible charge for an internal-combustion engine is produced by subjecting a mixture of air and hydrocarbon to the action of a heated catalyst, the temperature of the catalysed mixture being controlled either by passing the mixture through a cooler after issuing from the catalyser, or, if exhaust forms the source of heat, by passing the exhaust through a cooler before its passage around the catalyser or by adding cold air to the exhaust before it is admitted to the catalyser jacket. As shown in Fig. 1, fuel from a nozzle 4 mixes with air admitted at e and passes through an exhaust jacketted multitubular heater 1 the tubes of which are formed of, and may be packed with, one of the metals which are known when heated to effect the catalytic decomposition of hydrocarbon vapour. The catalysed mixture is drawn through a conduit 6 provided with a cooler 15 by a pump 7, and is supplied to a mixing-chamber 9 provided with a secondary air inlet 10 and connected to the engine 12. The cooler 15 may comprise a nest of tubes either cooled by air or surrounded by a jacket through which cooling water circulates, or may consist of a vessel containing cooling liquid through which the mixture is drawn. In the latter case, a liquid capable of absorbing the mixture may be used, a supply of mixture for starting being furnished by heating the vessel. The vessel may also contain filters. In modifications, the exhaust gases are cooled before their passage around the catalyser either bv a jacket through which air, water, or other fluid circulates or by admitting cold air to the exhaust through a valve which may be interconnected with the accelerator of the engine.

Filed: 1921-03-30
Abstract: 182,217. Rosak, K. March 30, 1921. Gauges; trueing rotating tools.-In a grinding- machine a turning or trueing device is provided which is set so that if the feed or advance of the grinding-disc, or of the work, is greater than that required to produce a desired dimension of work, the disc is turned or trued and consequently, on the next traverse, cannot remove further material from the work. As applied. to a cylindrical grinding-machine, Figs. 3 and 5. the diamond m or other turning-tool is mounted in a holder m<1> which is secured to a cylindrical block p slidable in a bracket o secured to the work-table e. The block has an extension q slidable in a slot in the bracket, and is pressed rearwards by a spring r. The holder m<1> passes through a slot s in the work-supporting centre l and is adjusted axially by a spindle w. This spindle is screwed and is rotatable, by means of a sleeve y, in a screwed sleeve u secured to a projection t of the bracket. The sleeve y carries a ring 2 having a graduated part 4 which co-operates with a scale 5 secured to the projection t. By means of the scales the diamond, which at the zero position of the scales lies on the axis of the work, can be set to come into operation when the grinding-disc d has been fed in beyond the radius indicated by the scales. The ring 2 is adjustable, to alter the zero setting, on the sleeve y and can be locked thereon by a screw 3; this adjustment allows for the effect of grinding discs of different grain and hardness. To remove the diamond tool, the block p is pushed forwards until the extension q is clear of the bracket; the block is then rotated 180‹ and is withdrawn backwards, the extension moving along a slot 24 in the bracket. The device is shown, in Fig. 6, applied to a surface grinding- machine. The zero position of the scales corresponds to the diamond lying in the plane of the work-table 8. The diamond-holder 13 is movable in a casing 12 by a screwed spindle 15 having an adjustable graduated head 20 which co-operates with an index 22. Reference has been directed by the Comptroller to Specification 168,307.
