Title: Improvements in or relating to fluid pressure brakes for vehicle trailers
IPC: B60T7/20
Filed: 1938-12-01
Abstract: 520,874. Fluid-pressure brakes. BOSCH GES. R. Dec. 1, 1938, No. 34969. Convention date, Dec. 1, 1937. Addition to 518,506. [Class 103 (i)] The invention of the parent Specification, comprising an auxiliary valve 16 operated by the draught coupling of a trailer vehicle against the action of a pre-tensioned spring 22 and controlling the supply of pressure fluid to a trailer brake cylinder 41, is now applied to a trailer brake system having a pressure controlled secondary valve 40 between an auxiliary reservoir 44 and the brake cylinder. According to the invention the auxiliary valve 16 is located between the secondary valve 40 and the brake cylinder 41. Fig. 2 shows the construction of the secondary valve 40 and the positions of the parts with the brakes released pressure being maintained in the control pipe 18<SP>1</SP> leading to the driver's valve on the towing vehicle. Spaces 49, 50, 51, and 52 within the cylindrical body of valve 40 are defined by a stationary partition 48 and a pair of pistons 46 and 47 carried by a tubular element 45. The air under pressure'in pipe 18<SP>1</SP> is applied to chamber 50 and passes through a charging valve 54 to chamber 51 and the auxiliary reservoir 44. The outlet of reservoir 44 is connected with a chamber 55 normally shut off from chamber 52, which is connected by means of a pipe 18 and through auxiliary valve 16 with the brake cylinder, by a valve 59. Chamber 49 is permanently open to atmosphere. Upon venting pipe 18<SP>1</SP> to apply brakes, pistons 46 and 47 move downwards, and tubular element 45 unseats valve 59 so that air passes from reservoir 44 and chamber 55 past valve. 59 to chamber 52 and thence through the auxiliary valve 16 to the brake cylinder 41. When pressure is applied to pipe 18' and chamber 50 to release the brakes, pistons 46 and 47 rise. Valve 59 consequently closes to cut off the reservoir 44 from the brake cylinder pipe 18 and, moreover, the tubular element 45 lifts off the valve 59 so that chamber 52 and the brake cylinder are vented through the bore in element 45 and chamber 49. The auxiliary valve 16 may be mounted on the bogie frame of the trailer instead of, as shown, on the yoke 10. The pivotal connection between the draw-bar 11 and valve rod 15 is then situated on the pivotal axis of yoke 10 so that the valve is not operated when the yoke is uncoupled and lowered to the ground. The arrangement of the auxiliary valve 16 between the secondary valve 40 and the brake cylinder enables both valves to operate simultaneously when the driver releases the accelerator and depresses the brake pedal, and avoids delay in application of the trailer brakes which would arise if valve 40 operated in succession to valve 16, owing to valve 16 being interposed between 18<SP>1</SP> and valve 40.

Abstract: 605,532. Autographic registers. SMITH & SON, Ltd., W. H., and FLAWN, P. A. Dec. 28, 1945, Nos. 35111/45 and 34760/46. [Class 106 (i)] [Also in Group XV] An oscillatory handle autographic register is characterised by a feed limiting device comprising a member arranged to stop movement of a driven member after a predetermined angular movement thereof corresponding to the feeding of a predetermined amount of stationery and a pawl movable by the handle and arranged to provide a one-way driving connection between the handle and the driven member and also as a preliminary to each feeding operation to disengage the stop member to release the driven member. Movement of the handle rotates a spindle 13 and a disc 14 first counterclockwise as seen in Fig. 3, and then, under spring action, back again. A driving pawl 27, pivoted to the disc 14, engages in one of four notches in a ring 19, first to eject a stop pawl 21 and then to drive the ring 19 which is secured to a gear driving the feed mechanism. At the end of a quarter revolution, the pawl 21 engages the next notch in the ring 19 to stop the feed, and the pawl 27 rides on the inside of the ring as the disc and handle return under spring action. Fig. 6 shows an inverted form with the stop pawl 55 on the inside of the ring and the driving pawl 57 on the outside. In Fig. 7, an arm loose on the spindle 63 carries a pawl 60 pivoted at 61. An arm 67 turns with the spindle, forcing the pawl 60 into a notch in counter-clockwise movement and withdrawing it in clockwise movement. The, handle 111, Fig. 8, carries the pawl 114 directly. The first Provisional Specification refers to Specification 586,987.

Abstract: 1366508 Air flow control dampers DANFOSS AS 3 Aug 1971 [3 Aug 1970 29 Jan 1971] 36399/71 Heading F4V [Also in Divisions F1 F2 and G3] An air-flow control valve, Fig. 5, for use in air-conditioning systems comprises a rigid control plate 24 rectilinearly or angularly movable to vary, e.g. the flow area through an orifice 23, the plate 24 being movable by a flexible chamber actuator comprising at least one inflatable flat bag 1, Fig. 4, mounted with the outer flat portions thereof in contact with the plate 24 and a fixed member 2. As shown the plate 24 is pivotable about an axis 7 to control the flow of air from an inlet chamber 21 to an outlet chamber 22. Movement of the actuator is dependent on the pressure difference across the bag(s). The bag(s) are subjected on the outside to the outlet chamber pressure and on the inside to a pressure in a line 31, 32, 6 connected to the inlet chamber 21 and having a discharge outlet controlled by a bimetal actuated obturating member 30. In Fig. 6, the actuator is mounted in a box 12, the pressure acting on the outside of the bags being taken from a static pressure tapping 6i and the pressure acting on the inside being taken from a total pressure tapping 6. Thus the actuator is responsive to the dynamic pressure and is said to control the plate 24 such that a constant air flow is produced even though the pressure in the inlet 21 varies. The actual air flow is determined by a manually adjustable flap 16 or automatically in dependence of a pilot pressure (Px) admitted to a further actuator (1<SP>1</SP>) which either affects the loading applied to the main actuator, Fig. 7 (not shown), or controls the flap (24<SP>11</SP>), Fig. 9 (not shown).  In further embodiments, Figs. 10 and 11 (not shown), an actuator having its bags 1 urged towards a collapsed condition by a spring (8), operates through linkwork a semi-cylindrical or sector shaped valve member (24a) controlling the proportionate flow from a pair of inlet chambers (21) to a single outlet or mixing chamber (22).

[Class 70] Rubber powder is made from rubber latex to which has been added sulphur or other vulcanizing agent, zinc oxide or other activator of the vulcanizing agent, and a stabilizer such as ammonia-caseinate solution, and which is then allowed to stand with or without acceleration by heat, until the tensile strength of a dried film or the coherence of a coagulum made from a portion of the mixture has substantially disappeared, the rubber then being separated as by spraying, or drying as a film, or coagulating and filtering or centrifuging. The product is a powder or may be easily disintegrated. The product appears to lie between the vulcanized and the unvulcanized states as part of the sulphur is combined, and by further heating, especially if an accelerator is present, the product reacquires tensile strength and the other characteristics of vulcanized rubber. Fillers, softeners, antioxidants and the like may be added to the latex, and where a large amount of sulphur is used, the product is suitable for the manufacture of an ebonite press powder. The product may, be dispersed in water or salt solutions to produce a latex, or swollen in a solvent to give a dispersion which may be ground to give a non-sticky paste of very high rubber content. The powder may be mixed with asphalt for road purposes, or alone or mixed with artificial resins as a moulding powder or be used in the manufacture of rubber derivatives.

[Also in Divisions B6, Gl and G4] A circuit producing a signal at an output terminal 80 if the light impinging on a photo-cell 13 exceeds a certain adjustable value, comprises four transistors 55, 60, 66, 73 connected so that the current produced by the cell 13 when the reflected light exceeds that value, causes the transistors 55, 60 to be cut off, thus placing the base 65 of transistor 66 at earth potential and causing transistors 66, 73 to be fully conductive so that a signal is produced at the terminal 80. The collector 68 of the transistor 66 is connected to the base of transistor 55 through a feed-back resistor 71 so as to apply a latch-back voltage. With the voltage developed by the cell 13 below a certain value, transistors 55, 60 are fully conductive causing base 65 of transistor 66 to become negative, thus cutting off both transistors 66, 73. An adjustable potentiometer 46 connected to the junction of cell 13 and base lead 54 is set to determine the light level at which a signal is produced. A diode 53 between the junction and the cell 13 prevents damage to the transistor 55 if the cell 13 fails.
