Title: Starting mechanism for internal combustion engines
IPC: F02N99/00
Filed: 1932-09-14
Abstract: 403,776. Turning-gear. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. Sept. 14, 1932, No. 25549. Convention date, Sept. 15, 1931. [Class 7 (v).] In a starting mechanism for internal-combustion engines which drive a supercharger or other auxiliary unit when operating under their own power, a coupling between the engine shaft and the auxiliary unit is automatically rendered inoperative during the cranking of the engine shaft from the starter. The coupling preferably consists of an overrunning clutch mechanism which couples the starter to the engine shaft during the starting operation and couples the engine to the auxiliary unit during normal running. As shown, the engine starter comprises an electric motor 13 mounted with its axis at right angles to that of the rotary supercharger 4 and driving through bevel gears 16, 17 a shaft 19, on a threaded portion 27 of which a clutch member 26 moves axially into driving engagement with a flywheel 32. The shaft 36 of the flywheel has a threaded portion 62 on which a clutch member 60 moves axially into engagement with a clutch member 61 on a pinion 43 connected to the shaft 6 of the supercharger 4 by a roller clutch 45. The pinion 43 is normally driven from the engine through a clutch 2, gears 106, 102 and a shaft 71 carrying a gear 67 meshing with the pinion 43. The clutch rollers 45, Fig. 2, co-operate with cam surfaces 44 on the inner surface of the pinion, and are guided by a cage 47, Figs. 2 and 3, one end of which carries conical members 49 registering with openings 50 in a control ring 51 rigidly retained in the pinion. The cage 47 is normally urged to the left by a spring 53, allowing sufficient play between the members 49, 51 to allow the rollers 45 to be carried into wedging relation with the cam surfaces 44 and the supercharger to be driven from the engine through the pinion 43. When the starter is in operation, the clutch member 60 moves axially into driving engagement with the pinion 43, while the hub 59 of the member 60 pushes the cage 47 to the right, bringing the conical members 49 into full engagement with the openings 50 of the ring 51. Thus the clutch rollers 45 are held out of engagement with the cam surfaces 44 and the supercharger is not driven, while the engine starter drives the engine through the clutch 60, 61, gears 43, 67, &c. The gear 67 is connected to the shaft 71 by a centrifugally controlled friction clutch comprising a disc 70 on the shaft 71 and a disc member 89, frictional engagement being obtained by means of weighted levers 94 preferably provided with springs 97 and acting through pins 96 on the disc 89. The levers are normally held in clutch-releasing position by a thrust bearing 98 moved to the right in Fig. 1 by a lever 101 and sleeve 99. At starting, when the motor 13 and flywheel 32 have been set in rotation, the thrust bearing 98 is moved to the left to allow the friction clutch to engage and the engine to be driven through the gear train 43,67,102,106.

Title: Improvements relating to colour television apparatus
Inventor: JAMES IVANHOE JOHN PENFOUND
IPC: H04N9/077
Filed: 1953-09-19
Abstract: 743,156. Colour television tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Sept. 10, 1954 [Sept. 19, 1953], No. 25907/53. Addition to 714,154, [Group XL (b)]. Class 39 (1). [Also in Group XL (b)] The target electrode of a pick-up tube employed in a colour television system (see Group XL (b)) is constructed as shown in Fig. 1 of a dielectric sheet 1 on one face 2 of which is deposited the normal mosaic of photosensitive elements and on the other face 3 of which are deposited two mutually insulated transparent signal output electrodes 4 and 5 arranged in the form of intermeshing vertical strips 6 and 8 connected together by transverse end strips 7 and 9. The strips 6 and 8 extend at right angles to the direction of line scan. An image is projected on to the target through a filter comprised of a repeating series of red, green and blue strip filter elements arranged parallel to strips 6 and 8 and of such a width that one group of three filter elements corresponds to each strip 6 and 8 as indicated by dotted lines 10. Preferably the filter elements are in the form of thin metallic films deposited over strips 6 and 8 and producing the desired colour selection by interference effects. In addition to the image, the target is continuously illuminated through the filter by a white biasing light. The signal trains derived from the two output electrodes then take the form shown in Fig. 3, wherein the signal groups 27 and 29 representing red, green and blue components of the image occur alternately in the two outputs and are each followed by a pulse 28, 30 extending below the level set by the biasing light. The pulses 28 and 30 serve to control the gating of the colour components into separate channels. As an alternative to the use of a biasing light, sheet 1 may be made slightly conductive and a positive bias potential (relative to cathode potential in a low velocity tube) applied to the two output electrodes so that the mosaic elements normally charge to the bias level by leakage through the sheet.

Title: Control of ph values
IPC: G05D21/02
Filed: 1972-06-02
Abstract: 1395232 Fluid-pressure servosystems; automatic control of pH FRIEDRICH UHDE GmbH 2 June 1972 25961/72 Headings G3P and G3R An electric signal linearly related to pH level in a conduit 3 is converted at 4 to a pneumatic signal which is fed directly at 5 to a max-select relay 7 also receiving via relay 6 the complement of the signal on 5, the output of relay 7 being fed via amplifier 8 to a further max-select relay 9 also receiving a constant bias signal on 10. In control unit 12, 13, the signal on A, which is related to pH as depicted at (e), is multiplied by the signal on 5 to produce a control signal which varies hyperbolically relative to pH as at (f), this control signal being applied at D to a console 14 for transmission to a valve 15 controlling addition of a pH regulator to conduit 3. The console 14 transmits a reference signal on C to unit 12, 13 corresponding to a desired pH. The conduit 3 may be transporting brine to an electrolysis cell, the hyperbolic relation between pH and the control signal on D being a good approximation to the logarithmic relation describing the titration curve. In an alternative system, console 14 applies a control signal directly to valve 15 and the signal on D adjusts the control signal to the working point on the titration curve, the control signal also being applied to unit 12, 13 to determine the working point. The systems may alternatively be wholly electrical instead of employing pneumatic relays &c.

Title: Improved oleo-pneumatic landing device for aeroplanes and the like
IPC: B64C25/60
Filed: 1935-09-20
Abstract: 463,059. Shock - absorbers. BILLE, P. P. H. Sept. 20, 1935, No. 26062. [Class 108 (iii)] In an oleo-pneumatic landing device for aircraft, oil is forced from a single tubular oilchamber 4 through damping valves and against floating pistons 11, 12 so as further to compress air contained in a plurality of chambers at least one of which is formed by a tube disposed adjacent the oil-chamber 4 which houses a load-supporting piston 3. As shown, a lowpressure air-chamber 13 and a high-pressure air-chamber 14 are disposed adjacent the chamber 4. The low pressure damping-valve device comprises a tubular member 15 having a conical valve-portion 16 normally engaging a fixed seat 17, and grooves 27, 29 in its upper end separated by a lip 28, the member being acted on by a weak spring 19 resting on the flanged end of a tubular member 20 which is slidable on the member 15 and is supported by a strong spring 22. A spring-pressed valve 23 having a fine hole 26 is housed within the member 15. The high-pressure valve device is similar to the low-pressure one, but the member 20, spring 19, and lip 28 are dispensed with. In operation, when a slight shock occurs, oil from the chamber 4 passes into the grooves 27 of the low-pressure valve device, forces the valve-portion 16 from its seat, and passes to the piston 11 which it depresses against the air pressure in chamber 13. When a severe shock occurs, the oil forces down the valve-portion 16 until it contacts with the member 20, and the lip 28 approaches the valve-seat 17 so that the resistance offered to the flow of liquid is greatly increased and the pressure in the oil chamber 4 rises to such an extent that the oil also causes 'compression of the air in the chamber 14. In a modification, one of the air-chambers is formed inside the piston-rod of the loadsupporting piston 3.

Abstract: 628,825. Gunnery training devices. ALRIC, G. C. A. Sept. 3, 1946, No. 26511. Convention date, April 26, 1940. [Class 119] A gunnery training device for practice in shooting at moving targets comprises a spotlight projector and a target-image projector, the latter moving across a screen, a target image whose size depends upon the range for which the gun is sighted, and the former being mounted on the gun barrel and being controlled by a trigger having a delayed action so that the time which elapses between the pressing of the trigger and the appearance of the luminous spot on the screen is equal to the projectiles time of flight for the chosen range. In the form shown the target image projector 1 projects a representation of a target on to a screen 10 representing a landscape or clouds, the position of the projector and, therefore, of the target on the screen being controlled by movement of a style 7 which follows a path on the map 9 conforming to the contours of the landscape shown on the screen 10. The size of the target is dependent on the distance between the style 7 and the vertical pivot of the projector and is controlled by the thread 13 which may move a mask 20, Fig. 2, with respect to the V-slot 19 in a plate 18 to alter the size of the target before projection. The elevation of the projector can be adjusted by means of the bar 16 which can be raised and lowered by a cam having graduations corresponding to the contour lines 11 on the map 9. A shooting projector is mounted on the gun (not shown), and pressure on the trigger causes a delay mechanism to work giving a delay corresponding to the time of flight of an imaginary projectile. After such delay a shutter opens and a spot of light is projected to record the point of aim. The delay set in is controlled by the thread 14 also depending on the distance between the style 7 and vertical pivot of the target projector. The thread may, in one example, control the inclination of a tube down which a ball runs to actuate, at the end of its run, an electric contact controlling the shutter.
