Title: Improvements in or relating to brake-control devices for motor vehicles
IPC: B60T13/16
Filed: 1934-12-04
Abstract: 448,617. Fluid - pressure brakes. VAU, J. B. P., 1, Rue Jules Guesde, Saint-Ouen, Seine, France. Dec. 4, 1934, No. 9489/36. Convention date, March 8, 1934. Divided out of 449,904. [Class 103 (i)] In a hydraulic circulating brake system the throttling means for applying the brake comprises two members 18, 13 one connected to the brake pedal and the other subject to the braking pressure and to a spring 10 so that a graduated brake application is obtained. Liquid is circulated by a pump from a tank 1 through pipes 2, 16, orifice 15, orifices 17 in the piston 13, chamber 4 and pipe 5 back to the tank. A piston 7 is held in such a position by the spring 10 bearing against the piston 13 and a spring 11 bearing against the casing that it closes ports 9 connecting the pipe 2 and the cylinder 4. If the output of the pump increases the piston 7 is raised to allow the pressure to be released into the cylinder 4. To apply the brakes the member 18 is depressed by the brake pedal to close the orifices 17 and create braking pressure in the pipe 2 and the pipe 6 leading to the brakes. This pressure also acts above the piston 13 and forces it down until the orifices 17 are again opened whereupon the brake cylinder pressure will no longer increase. The downward movement of the piston 13 increases the pressure on the spring 10 and the piston 7 closes the ports 9. This cycle of operations takes piece at each braking stage. Reduction of brake pressure is similarly graduated. A residual pressure is maintained in the brake pipe 6 in release position by the spring 11 acting on the piston 7 and the smallness of the aperture 15. Two systems are combined to operate the front and rear brakes and are operated by arms on a shaft 20, one arm being fixed and the other adjustable so that the control members do not have the same braking position at the same time. A stop operated by a Bowden cable limits the movement of the shaft 20. The pedal operating the brake has lost motion relative to the shaft 20 in order that the pedal can be used to control the throttle of the vehicle engine.

Title: Voltage-to-frequency conversion apparatus
Inventor: NEWBOLD WILLIAM FISHER
IPC: G06G7/20
Filed: 1969-02-21
Abstract: 1,268,649. Automatic frequency control; pulse modulation circuits. HONEYWELL Inc. 21 Feb., 1969 [1 March, 1968], No. 9491/69. Headings H3A and H4L. [Also in Division G4] A circuit for providing an output whose frequency is proportional to the amplitude of the input comprises an operational amplifier 13 feeding a voltage-to-frequency converter 14, a degenerative feedback signal being fed from the converter to the input of the amplifier. The amplifier 13 (not described in detail) is of the kind which maintains the feedback current I 2  equal to the input current I 1  whereby, since I 2  is proportional to the output frequency of the converter, the frequency is proportional to the input signal. Input signal I 1  and feedback signal I 2  are fed to a common junction and thence to one terminal of the amplifier 13. The output of the amplifier controls the conduction of transistor 53 which determines the rate of charge of capacitor 64. As the capacitor charges, the voltage on the cathode of SCR 63 falls until it reaches the bias voltage supplied by potentiometer 57-60, whereupon the SCR fires, discharges the capacitor and returns to non- conductive condition. A voltage developed across resistor 62 by firing of the SCR causes output transistor 67 to conduct. The output, in the form of voltage spikes, is fed to a flip-flop 70 having outputs A 1 , B 1  which are alternately energized. The outputs are coupled via circuits 47, 39, 37 and 48, 40, 38 to the bases of transistors 30, 31 which are alternately rendered conductive, and regulate the charge and discharge of a precision capacitor 34. The capacitor is charged from a source of constant voltage E R  so that discharge current I 2  (smoothed by capacitor 33) is proportional to the frequency of the flip-flop and hence of the converter 14. Transistor 56 provides a low limit bias to the capacitor 64, i.e. it supplies current to the capacitor when the output of amplifier 13 falls sufficiently to cause transistor 53 to approach cut-off. When the amplifier output reaches a certain minimum value, transistor 68 becomes conductive and terminates operations by grounding the outputs of the flip-flop 70. An output circuit 16 (Fig. 4, not shown) consists of a second flip-flop driven by the flip-flop 70 and, in turn, driving the winding of a motor through a pair of alternately conducting transistors. The motor moves through one increment as each transistor conducts and thus performs an integration. An alltransistor version of the converter 14 is described with reference to Fig. 4 (not shown).

Abstract: 1387621 Making cables IMPERIAL METAL INDUSTRIES (KYNOCK) Ltd 30 March 1972 [15 April 1971] 9495/71 Headings H1A and A4D A metal composite is made by assembling a plurality of longitudinally extending elements of a non-ferromagnetic metal having an electrical resistivity at 0C of less than 3 micro ohms cm., separating each element from the other elements by a layer of metal having a higher electrical resistivity than that of the first mentioned metal, screwing the assembly together, and longitudinally extending the assembly to elongate the elements to produce filaments and to metallurgically bond the components of the assembly together. In one embodiment, Fig. 4, rods 5 of hexagonal crosssection are produced by extruding at a temperature of 550C and then drawing an assembly comprising a high purity copper rod which has been inserted in a tube of a copper 30 wt. per cent nickel alloy. The rods 5 are then inserted in a can 6 of the above cupro-nickel alloy, with cupro-nickel covered copper cores 6a filling the extra spaces, and the assembly extruded at 950C and drawn. In the embodiment of Fig. 6 strips of Ti 6 wt. per cent Al 4 wt. per cent V alloy are inserted in longitudinal slots in the outer wall of a copper can and a can of the above titanium alloy slid over the copper can. The assembly is then extruded at temperatures from 450-580C and machined to produce a composite can as shown in Fig. 6, having an outer sheath 11 of the titanium alloy with segments 12 of the titanium alloy separating parts 13 of copper. The composite can is then filled with copper filaments 9 covered in the titanium alloy and then assembly extruded at a temperature of 500  75C. A composite tube, as shown in Fig. 8, having segments 20 of copper and shells 22 and 23 and barriers 21 of the cupronickel alloy, is formed in a similar manner to the formation of the composite can of Fig. 6 without the machining step. In the embodiment shown in Fig. 9 aluminium wires 25 covered with a copper 1 wt. per cent tin alloy and having a hexagonal cross-section are inserted between the copper-tin alloy tubes 27, 28 and the assembly extruded at 350-450C and drawn to give a hollow tube. Examples of other alloys used are described in the Specification.

Title: Improvements in winches
IPC: B66D1/36
Filed: 1939-03-27
Abstract: 526,862. Winches. RING, J. March 27, 1939, No. 9558. [Class 78 (v)] Means for guiding the rope evenly on to a winch drum comprise an outer steering device and an intermediate guide consisting of a curved member, the curve being such that the length of rope between the outer steering device and the point of contact of the rope and drum is always constant. Fig. 2 shows an intermediate member in the form of a rod 4 curved upward from each end B<SP>1</SP>, B" to its middle B. The rope 2 follows this curve as it passes from the outer steering eye A to wind on the drum 1, and friction may be reduced by passing the rope over a reel sliding over the rod 4, or by replacing the rod by a pulley wheel carried on the outer end of a pivoted arm. Fig. 7 shows a development of this latter form, in which the lower end of the pulley carrying arm 6<SP>1</SP> is fitted with a wheel 8 riding on a curve 9. Fig. 10 shows a further form in which a bulged roller 15 takes the place of the rod 4. To compensate for the increase in effective diameter of the drum as more layers of rope are wound on, a construction shown in Fig. 13 may be employed. The intermediate guide consists of a pulley 21 suspended beneath a truck 25 riding on curved rails 22, and the outer steering pulley 3 is carried on a lever 18 pivoted at 19 and fitted with a roll 20 at its inner end which bears on the coiled rope and rises therewith, thus lowering the pulley 3 and maintaining, in conjunction with the curve of the rails 22, constancy of length between the pulley 3 and the drum contact point. Fig. 14 shows a modification of this type which allows for change of direction of approach of the rope to the winch, the device pivoting about the drum axis 1<SP>1</SP>. The intermediate guide 5<SP>1</SP> is here of the form shown in Fig. 7.

Abstract: 181,524. Cohn, S. April 1, 1921. Incandescent-lamp-mantle sewing-machines. - A slotted beam 44, 45 with thread-clamping devices at each end, is rotated from a shaft 11, to lay a thread between radial cutting-edges of discs 65, 66, and in the open eyes of latch-needles 21. Side folders 3 are mounted on pivoted levers 5, which are oscillated by pins 7 working in slotted discs 10, Fig. 3, mounted on the shaft 11. A slotted crank 16 is fixed to a shaft 15 and is rotated through mutilated bevel gearing 13, 14 from the shaft 11. The crank 16 reciprocates a block 19 carrying the needles 21. Levers pivoted in the arms 44, 45 carry vertical plates 50, notched at 51, and concentric with shoes 46 on the arms. A pivoted lever 55 is oscillated from a cam disc 52 by a rod 54 to rotate the lever on the upper arm, Fig. 2, and thereby clamp the thread in the notch 51, between the plate 50 and the shoe 46. Of the cutting discs 65, 66 which are rotatably mounted on a shaft, one is integral with an arm 68, which rocks on a bracket 69 and the other is integral with an arm 70 which is connected by a bell-crank lever 71 to a bar 72, reciprocated from a cam disc 75 on the shaft 15. A pivoted tripping-member 29 opens the latches of the needles on their forward motion, and another tripping-member 27, Fig. 16, closes them on the return. A hand-lever 12 is used to rotate the shaft 11, first counterclockwise to the operator, then clockwise. The thread end is clamped in the upper arm at the end of an operation, and, as the next begins, the fabric is pleated, the needles are pushed through it, and the beam 44, 45 is turned through half a revolution by gears 34, 35, 38, and a one-way ratchet-and-pawl connection, to lay the thread in the needle barbs. Just before the end of this movement, projections on the lever 47 hit sloping shoulders 63 on the standard 64, and the clamps are opened so that the thread enters the rising notch 51. Further rotation closes the upper clamp, and then cuts the thread. Return motion retracts the needles to draw the thread through the fabric, opens the folders and the cutter, and retracts the lever 55.
