Title: Improvements in or relating to traffic actuated signalling apparatus
IPC: G08G1/02
Filed: 1933-04-07
Abstract: 415,200. Road signals for controlling traffic. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd., Caxton House, Tothill Street, TYACK, F. G., 21, King William Street, Greenwich, and RIDDLE, H. J. N., Central House, Kingsway, all in London. April 7, 1933, No. 10435. [Class 118 (ii).] A restraining member associated with a fluid operated directional road pad is operative when a vehicle actuates the pad in the non-signalling direction to prevent operation of the member controlling the signalling apparatus. The invention is described in connection with a road pad of the type described in Specification 400,340. The inlets 3 and 4 are connected to the air chambers in the road pad. If the chamber associated with inlet 3 is operated first, bellows 22, 23 is effective and plate 20 is rotated about hinges 27 to lift the plate against back stop 44. The chamber associated with inlet 4 becomes effective immediately afterwards, but the end of plate 20 prevents plate 21 being lifted sufficiently to close contacts 33, 38. The upturned end 34 of plate 21 holds plate 20 until the pressure is removed from the second chamber. If, however, the vehicle passes in the operating direction, plate 21 is lifted first to close contacts 33, 38 and plate 20 is prevented from operating by the end 34. Felt washers 17 allow excessive pressure in the air bags to leak away. To damp air vibrations in the pipe system the baffle shown in Fig. 4 is provided and comprises a wire 48 on which beads 49 of slightly less diameter than the pipe are threaded and sweated in position.

Title: Method for transmitting television
IPC: H04N5/067
Filed: 1935-04-05
Abstract: 457,879. Television. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. April 5, 1935, No. 10553. Convention date, April 6, 1934. [Class 40 (iii)] At a transmitter in which synchronizing signals and picture signals are separately amplified before mixing, the picture signal amplifier contains a limiting device so that image potentials of such sign and magnitude as are likely to interfere with the synchronizing signals are subjected to limiting. A gas-filled diode 14 is connected between the grid of the last valve 10 of the image amplifier and earth so that the diode becomes conducting when the image potential approaches the synchronizing signal level. The cut-off level may be varied by adjusting the anode potential 13 of the diode 14. To prevent the diode 14 cutting off a considerable range of the picture signals, the output of valve 10 is rectified at 17 and applied to the grid of an earlier valve 9 in the image amplifier so that variation of the potentiometer 22 varies the amplification of valve 9. The picture signals themselves therefore control the amplification so that on changing from a " thin " to a "dense" film no manual adjustment is required.

Title: Improvements in apparatus for feeding tobacco and like material
IPC: A24B7/14
Filed: 1942-07-29
Abstract: 558,788. Conveyers. MOLINS MACHINE CO., Inc. July 29, 1942, No. 10581. Convention date, Aug. 5, 1941, [Class 78 (i)] Apparatus for feeding tobacco and like materials comprises a conveyer 20 having depending vanes or rods 24, for sweeping the material along the lower supporting surface 15 of a trough in which are arranged openings for feeding a series of hoppers 11, one only of which is shown, and which feed machinery for the further treatment of the material. To control the supply to the hoppers 11 each hopper is provided with a slidable closure member 35 connected by a rod 39 to a crank 40 which is loose on a spindle 41 and which carries a spring urged pawl 45 the tail 52 of which is held by a recess in a spring urged catch 55. When the level of material in the hopper falls below level B, a flap 26 is uncovered and moves about a pivot 27 to allow a weighted arm 28 to operate a switch 32. This energizes a solenoid 64 to move catch 55 so as to release pawl 45 allowing it to engage a slot in a disc 42 continuously rotated by the conveyer mechanism. This drives crank 40 to move slide 35 to the open position until pawl 45 is disengaged from disc 42 by engaging a spring urged catch 56; where it is held. Material then feeds into the hopper 11 until flap 26 is moved down and arm 28 moves up to close switch 31. This energizes a solenoid 67 to operate catch 56 so as to release pawl 45, causing crank 40 to be driven back to the position shown to move slide 35 to the closed position. The speed of rotation of disc 42, and its setting relative to the conveyer are such that slide 35 moves at the same average speed as the conveyer 20 and commences to move, in the closing direction, when one of the vanes 24 is level with its leading edge. This prevents material jamming in the opening. Specifications 365,997, 366,479 and 482,005, [all in Group I], are referred to.

A cylindricalthroughway plug-cock which has its two ports 3, Fig. 1, of circular rectangular or oval cross-section, embodies an annular groove 8 of varying depth in the plug chamber and around each port 3; each groove 8 houses a sealing ring 9 that bears on the plug and is spaced from one wall of its groove to form a chamber 8a. The surface of the sealing rings 9 in contact with the plug is arcuate; the rings 9 are resilient and moulded from natural or synthetic rubber or other plastic material. Any fluid leaking past the inlet sealing ring enters the corresponding chamber 8a and urges the ring more tightly against the plug. In another form each ring 9, Fig. 5, is held in place around its port by a sleeve 15 pinned or screwed in position. In a further form, the plug is conical and moved axially before it is rotated by a lever acting on a cam surface; the sealing rings are of non-resilient material. The chamber of the upstream ring may be connected to the pressure fluid by a separate duct; this pressure fluid may be obtained from a separate source. Lubricant sealing may be additionally employed.

Abstract: 1,271,206. Sorting machines. MANDREL INDUSTRIES Inc. 6 March, 1970 [7 March, 1969], No. 10955/70. Heading G4H. A sorting machine comprises devices 24, 26 for providing a series of clock pulses 36 in synchronism with the rate at which products 18 are being conveyed and inspected, a circuit 22 for generating a rejection pulse in response to the sensing of a bad product 18<SP>1</SP> by an inspection station 20 and a shift register 38 controlled by the clock pulses to generate, after a selected time delay, an output signal for causing operation of an ejector 16 when the bad product is adjacent thereto. The products 18 to be inspected for discolouration are mounted on ferrules 14 positioned on the periphery of a drum 12 which is indexed past the stations 16, 20. The devices 24 and 26 comprise metallic slugs and a magnetic pick up head respectively which in conjunction with a multi-vibrator 32 and amplifiers 30, 34 produce the clock pulses. The shift register 38 consists of a number of stages 40, 42, 44, 46 equal to the number of positions between the stations 16 and 20. Hence if a bad product is sensed a pulse is fed from the circuit 22 to the first flip-flop 40 to change its state. The states of the succeeding flip-flop & 42, 44, 46 are therefore changed in sequence at the rate of the clock pulses 36 so that when the bad product has reached the ejector 16, a pulse is received by an ejector driver 48 which causes the ejector to displace the bad product by providing a blast of air. The slugs 24 may be replaced by holes in order to generate the clock pulses photo-electrically. In a modification additional multi-vibrators controlled by potentiometers are provided to vary the duration and phasing of the ejection air blast.

Abstract: 246,702. Frederiksen, H. O., and Ras mussen, L. E. April 29, 1925. Stencil switches; pneumatic action. -Relates to a contact device for electrical illuminated advertisements by means of which the current is conducted to a large number of electric lamps, arranged in parallel lines, forming a lamp field in such a manner that an illuminated letter or design is produced, moving in the direction of the lines. A cylindrical drum 1 having an integral disc 2 and a round pulley 3 rotates on a stationary hollow shaft 4 which serves as a conduit for the conductors and is also connected to a vacuum pump. The, disc 2 is provided with conducting plungers 13 arranged in a series of circles and each connected as shown to a flexible pipe. Arranged non-rotatably above the discs 2 are a disc 8 having contact studs arranged as shown in Fig. 2 and also a sector 7 arranged in the same plane and having a curved under-surface to depress the plungers 13 out of contact with the contact studs at the appropriate time. Yielding contacts 12 are arranged on a non-rotating disc 9 so that the disc 8 and the sector 7 may be removed without having to disconnect the wire conductors. An elastic belt 28, perforated according to the letters to be formed in the illuminated field, passes round the cylindrical drum 1 and is guided by rolls 17, 27, Fig. 6. The partial vacuum within the cylindrical drum 1 causes such of the plungers 13 as become exposed to atmospheric pressure, by means of the flexible pipes and apertures in the belt 28, to be forced into contact with the contact studs immediately above them causing the appropriate lamp to be lit. The rotation of the drum causes successive lamps on the same line in the lamp field to be lit until such time as the plunger is depressed by the undersurface of the sector 7. The belt 28 is provided with holes 14 which normally correspond with holes 14 on the drum, but as the belt stretches in use these holes fail to register and the difference between the pressure within the drum and the atmospheric pressure is caused, by means of the pipe 23, to operate a plunger 19, Fig. 6, in a cylinder 20 and so brake the roll 17 until a balance is reached. The stretch thus obtained determines the positions in which the perforations in the belt 28 are to be made. If a non- elastic belt is employed, projections on the drum 1 may register with aperatures in the belt to maintain the correct relationship.

Abstract: 1298593 Moulding filters STANDARD SCREW CO 9 March 1970 [10 March 1969] 11204/70 Heading B5A [Also in Division B1] A filter comprising a housing 10 closed by a cover-plate 22 and containing a transversely extending pleated filter element 12 is made by locating the cover-plate upon a mould 30, the cover-plate being provided with apertures 52 through which pins 44 and 46 carried by the mould plate project, casting a layer 20 of heat setting plastisol of, for example, PVC upon the cover-plate, and whilst the layer is still sufficiently fluid, applying the housing and filter element to it so as to embed the rim of the housing and one edge of the filter element in the layer. The layer is then heat set. Pins 44 project beyond the surface of the layer to form preformed inlet apertures whereas the layer extends over pin 42 to form a thin region rupturable just before use to form an outlet aperture. Pins 44 are apertured to allow the expanding air within the housing to escape during the heat setting of the layer. The other edge of the filter element may be bonded to the housing by a cast layer 18 of a suitable plastisol. Recesses in the mould about the pins 44 and 42 form resilient mounting grommets 58 and, if desired, these recesses may be filled with a more resilient material before the latter 20 is cast. As in Figure 1, a composite mould may comprises a series of moulds located sideby-side each surrounded by an upturned material retaining wall 34.
