Title: Improvements in or relating to brake-gear for railway and other vehicles
IPC: B61H15/00
Filed: 1929-03-01
Abstract: 329,416. Metropolitan-Cammell Carriage, Wagon, & Finance Co., Ltd., and Champeney, C. C. March 1, 1929. Compensating for wear.-In automatic slack adjusters for railway and other vehicles a lever or other part of the operating mechanism and a stop-engaging member moving normally with the lever are connected to a brake-applying rod or the like by pawls engaging independent ratchet teeth on opposite faces of a slot in a head on the brake rod so that when the brake is applied after wear has taken place the stop-engaging member abuts against its stop and engages and holds the brake rod to permit the lever to advance its engagement therewith. Upon any relative movement between the brake rod and operating lever other than that permitted by the stop device both pawls will ride up the faces of their ratchet teeth simultaneously and will lock against each other. The brake lever c is connected by means of a guided compression spring p to a lever m free to rock on the brake shaft b. The lever m carries a pin l travelling in an arcuate slot n and carrying a link k engaging by means of a pawl j ratchet teeth h in a slot on the end of the brake rod f. Ratchet teeth g are engaged by a pawl d on the brake lever c. The levers c, m move together on brake application until slack occurs when the pin l engages the end of the slot n and the spring p is compressed, and the pawl j takes up a tooth of the rack h. When the brake is released the pawl j holds the 'brake rod so that the pawl d rides over a tooth of the rack g. In a modification the rocking movement is replaced by a sliding movement, and the mechanism comprises a frame sliding on two parallel rods and connected to the brake operating rod and carrying a pawl engaging the teeth on one face of a slot in a head joined to a second frame sliding on the rods and connected to the brakes. A bar is caused to slide on the rods on brake application by the first frame by means of springs until it engages adjustable washers when the springs are compressed and a pawl connected to the bar and engaging teeth on the opposite face of the slot in the head takes up a tooth, thus the head is held when the brake mechanism returns and the pawl on the frame rides over a tooth of its rack. The teeth with which the stop operated pawl engages may be half the pitch of the teeth with which the pawl on the operating lever or bar engages and which engages alternatively with staggered teeth on two ratchets of which one is integral with the brake rod and the other is formed on a plate pivotally secured thereto so that an amount of slack equal to half the pitch of the teeth can be taken up.

Title: Improved apparatus for forming the combustible charge for an internal combustion engine
IPC: F02M69/40
Filed: 1958-03-03
Abstract: 816,649. Spray carburetters. GENERAL MOTORS CORPORATION. March 3, 1958 [March 14, 1957], No. 6696/58. Class 7(3) A fuel metering device, in which the fuel is controlled by the suction produced by a venturi 16 in the air intake pipe 12, is supplied' through two separate supply pipes 34, 66, and comprises a control valve 68 which, under normal running conditions blocks the pipe 66, and at starting permits fuel to be supplied from both pipes. The pipe 34 is supplied by an engine driven pump 32 and opens into a chamber 52 beneath the valve 68 which comprises a sliding portion having a passage 76 through which the fuel flows into a space 38 connected by ports 42 to an annular space 46 supplying the pipes 90 leading to individual nozzles 91 in the intake passages 20. The quantity of fuel delivered to the nozzles is controlled by a by-pass metering valve comprising a sliding sleeve 50 controlling by-pass ports 44, the sleeve being controlled in accordance with the intake air flow by a linkage 100 connected to a diaphragm 108 actuated by the suction produced by the venturi 16. During normal running the delivery pressure of pump 32 lifts the valve 68 against its loading spring 72 and blocks the auxiliary supply pipe 66 but at starting the spring 72 overcomes the pump delivery pressure and forces valve 68 down against a stop 74 to open the auxiliary supply pipe 66 which is fed by a separate pump 24. The suction from venturi 16, transmitted through pipe 118 to the diaphragm 108, is reinforced at idling by the suction in a by-pass 128 around the throttle valve and at cold starting an enriched mixture is obtained by connecting the diaphragm space 112 through a pipe 132 to the induction pipe downstream of the throttle valve 18. A valve 144 in the pipe 132 is opened at cold starting by a bimetallic coil 152 which also controls a fast idle cam 158. To prevent destruction of the suction in pipe 132, the pipe 118 is closed at speeds below idling by a valve 162 actuated by the suction in pipe 118. The pump 24 supplies the float chamber 28 in which the pump 32 is situated and is provided with a pressure-relief by-pass 96.

Abstract: 780,819. Cathode ray tubes. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. March 8, 1955 [March 17, 1954], No. 6767/55. Class 39(1). An image intensifier comprises a photocathode 5, Fig. 1, excited directly by a light image or indirectly by an X-ray image, a reducing electron lens, e.g. electrodes 7, 8 for forming a conductivity image on B.I.C. (bombardment induced conductivity) layer 15 of target 12 and an electron beam for scanning the rear side of target 12 to read and erase the conductivity image and a load circuit 24 coupled between metal layer 14 and the scanning beam cathode the metallic layer 14 being on the side facing the input screen. The input screen 2 exposed to the X-rays comprises fluorescent (ZnCdS) layer 6 which converts the X-ray image to a light image which excites photocathode 5 (Cs-Sb) there being intervening layers of glass 4 and transparent conductive material 3. The electron image from 5 is focused down to as small a size as possible on target 12 by lens electrodes 7, 8. Target 12 comprises an open mesh 13 coated by evaporation with secondary emissive material such as K Cl or Au, an electron permeable Al layer 14 and a B.I.C. layer 15 of arsenic trisulphide. The rear face of B.I.C. layer 15 is scanned by a high velocity beam 16 from gun 18 to restore its areas to cathode potential the output signal being taken from the target 12 across resistor 24. The scanning beam 16 is controlled by aligning coil 23, focusing coil 22 and scanning coils 21. The secondary emissive layer 24 on mesh 13 gives a secondary emission ratio > 1 so that the total secondary emission ratio of the target 12 (considering both sides) is approximately unity, and lens electrode 8 collects secondary and back scattered electrons from mesh 13. A non linear amplifier is connected between the tube and a reproducing tube to enhance the contrast. The electron B.I.C. material can be Sb 2  S 3 , Se, Cd S, S, Al 2 O 3  or anthracene. If the fluorescent layer 6 is omitted then a light image can be focused on photocathode 5.

Title: Improvements in engine starters
IPC: F02N15/06
Filed: 1924-03-17
Abstract: 225,757. Rogers, F. H., (Eclipse Machine Co.). March 17, 1924. Turning-gear.-In an engine starter comprising a shaft 3 mounted for longitudinal and rotary movement and carrying a loosely-mounted driving pinion 9 and a control member 11 mounted for longitudinal movement thereon and rotary movement therewith, a spring 24 urges the member 11 towards the pinion 9 and a driving connection between the members 11, 9 is under the control of the member 11. As shown, the shaft 3 is a sleeve sliding on splines 4 on the armature shaft 2 of an electric motor and moved axially by means of a shifter sleeve 7 engaged by a lever which may also switch on the motor. The sleeve carries a stop 6 for the pinion 9. The member 11 is internally threaded to engage screw threads 10 on the sleeve, and is connected to the pinion by a multiple-plate clutch, the plates 12, 13 being connected alternately to the pinion and to a drum 14 secured to the member 11 by interfitting tongues 20. The clutch plates are held in assembly by means of a flanged shell 22 and a locking ring 23, and by a locking wire 18 in a groove 19 in the pinion. At starting, the sleeve 3 is moved axially by the lever to bring the pinion into mesh with teeth on the fly-wheel, and the motor is switched on. The clutch is then tightened by the action of the screw-threads 10 and the pinion 9 is driven from the armature shaft. When the engine over-runs the pinion, the clutch is released by the screw action. If the teeth of the pinion clash with those of the fly-wheel, the continued axial movement of the sleeve 3 rotates the member 11 and the pinion, by means of the screw-threads, sufficiently to bring the pinion teeth into register between those of the fly-wheel.

Title: Improvements in and relating to television standards conversion
Inventor: EDWARDSON STANLEY MAKINSON
IPC: H04N7/01
Filed: 1963-02-22
Abstract: 993,191. Television standards conversion apparatus. BRITISH BROADCASTING CORPORATION. Feb. 20, 1964 [Feb. 22, 1963], No. 7341/63. Heading H4F. In an apparatus for television standards conversion in which input signals whose line standard is to be changed are applied to produce a visual display upon the screen of a cathode-ray tube and the display is viewed by a camera tube operating at the same field frequency but at the desired different line frequency, the field scan, curve (b), Fig. 2, in the camera tube is delayed relatively to the field scan, curve (c), in the display tube by less than the field-blanking interval and means are provided, operating during the times of overlap OT between the camera and display tube blanking intervals, to reduce the charge difference, curve (a), over the target of the camera tube. The effect of the invention is to eliminate spurious images due to failure in the camera tube to erase completely in one field scan the charge image which is formed on the target. A pulse, curve (d), is derived during the overlap period and is applied to control the camera operation. When the camera is an " Orthicon "or" Emitron " (Registered Trade Mark), Fig. 3, the pulse is used (a) to produce a pulse of light which is caused to flood the side of the target 11 on which the display image is focused and (b) to drive the stabilizing mesh negative. Photo-electrons emitted from the target by the pulse of light are impelled back to the target and redistributed so as to reduce any charge differences. The net change of target charge is zero if all photo-electrons are returned to the target, any tendency of the electrons to be collected by other electrodes, such as the wall anode being prevented by also pulsing such electrodes negatively. Where the camera is on Image-Orthicon, Fig. 4, a pulse of light is impinged on the photo-cathode and the field mesh 18 is driven positively. Secondary electrons released from the target 16 by the photo-electrons are returned to the target by the retarding field due to mesh 18 and are redistributed so as to reduce charge differences. The target acquires a net negative charge however which must be overcome before a useful positive charge can be stored. This may be overcome by biasing the display tube to produce a fixed minimum brightness as shown in Fig. 5. The picture information will then be displayed on a substantially linear part of the tube characteristic, thereby eliminating or reducing the need for gamma correction. In another way of operating with an Image- Orthicon camera, Fig. 6 (not shown), the photo-cathode is pulsed with light and is also raised from its normal negative potential to zero potential. The accelerator electrode in the image section is also raised to a low positive voltage below the first cross-over potential. The overall effect is that the target is stabilized at the zero potential of the cathode.
