Title: Improvements in or relating to lifting jacks
IPC: B66F1/00
Filed: 1932-10-12
Abstract: 408,646. Lifting-jacks. LAKE & ELLIOT, Ltd., Albion Works, Braintree, and RUBURY, J. M., Little East, Bocking, both in Essex. Oct. 12, 1932, No. 28490. [Class 78 (iii).] In a jack of low initial height the crutch is carried on a lever or pair of levers 50 pivoted at 49 on a pair of levers 48 which are pivoted at 45 on the frame 44, and the lever 50 is operated by a lever 54 pivoted on the frame at 55 and connected with the lever 50 at 53 so that initial movement of the operating lever from the position shown causes only a slight movement of the fulcrum 49 due to the lowering of the point 53 but further movement displaces the lever 50 forwardly swinging the fulcrum 49 about the pivot 45. The crutch moves substantially in a vertical line. As shown in Fig. 2 the jack is provided with wheels 46 at the forward end and the levers 48 are pivoted upon the axle. The crutch is retained in the raised position by a pawl 63 on the operating lever engaging teeth 65 on the frame. The rear end of the frame is connected to a U-shaped block 47 forming a support. As shown in Fig. 4, the levers 50 are actuated through reversible ratchet mechanism. The levers 50 are pivoted to crank pins 66 on a ratchet wheel 67 on the base 47. A lifting pawl 69 is pivoted on the operating lever 54, and a holding pawl 70 is pivoted on the base. The pawls are held in lifting position, Fig. 6, or lowering position Fig. 4, by a flat spring 74, according to the setting of a cam 76 on a pedal lever 75.

Title: Improvements in or relating to pulsed radar systems
Inventor: GRAY TREVOR
IPC: G01S7/12
Filed: 1952-11-12
Abstract: 739,165. Pulse radar; cathode-ray tube circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Nov. 3, 1953 [Nov. 12, 1952], No. 28562/52. Class 40 (7). Relates to a pulse radar having a P.P.I.' display in which the output, Fig. 2 (a) from a pulse generator A, Fig. 1, triggers a flip-flop B whose output (b) controls the duration of the voltage output (g) from a time base generator C which is applied to the rotor of a magslip G producing two resolved sawtooth currents for the deflection coils E of the C.R.T. A sawtooth output (c) from C is applied to a discriminator D of the type disclosed in Specification 718,059 which produces positive and negative pulses (d) when the forward and back strokes of the sawtooth pass through the mean level ML of the sawtooth waveform, the cathode-ray beam being at the centre of the screen at such instants. The positive pulses (d) are applied to trigger the transmitter and also a flip-flop F whose output (f) is applied to intensify the cathode-ray beam during the effective portion T2-T3 of the forward sweep of the time base. According to the present invention the flipflop F, Fig. 4, comprises a cathode-coupled pair of triodes V1, V2 (normally cut-off and conductive respectively), the anode of a normally cut-off triode V3 being directly connected,to the anode of V2. The positive pulses from D applied to the grid of V1 trigger the flip-flop and the waveform (g) from C is applied to the grid of V3 so that at time T3, V3 becomes conductive and terminates the positive output pulse (f) from the anode of V2, the flip-flop being restored to its equilibrium condition at time T4 by the negative pulse from D; the positive pulse portion of waveform (g) is preferably extended beyond time T4 by an R.C. circuit. Alternatively an inverted form of waveform (b) may be applied to the grid of V3. The use of V3 ensures that the termination of pulse (f) is independent of the response time of the flip-flop thus allowing the use of triodes even though the time base speed is high. The rise time of the leading edge of pulse (f) is rather lengthy but this effect can be offset by advancing the timing of the positive trigger pulses from D. A known form of flipflop using a pair of cathode-coupled pentodes and diode clamps for terminating the output at a selectable time is illustrated in Fig. 3 (not shown).

Patent GB-726814-A (GB)
Title: Improvements in or relating to a mould for forming an article by compression moulding
IPC: B29C33/02
Filed: 1952-11-14
Abstract: 726,814. Moulds for rubber &c. SCHERER CORPORATION, R. P. Nov. 14, 1952 [June 24, 1952], No. 28756/52. Class 87 (2) Relates to moulding cup shaped or tubular articles from material such as rubber and consists in. a self-trimming mould comprising two co - acting mould halves having narrow lands or parting surfaces rendering said mould halves subject to damage on over-stressing, plates having aligned recesses for slidably receiving said mould halves, and a generally columnar member in one of said recesses for spacing the mould half seated in said one recess from the bottom thereof, said columnar member being more readily deformed than the mould half supported thereby on overstressing of said mould half, and said columnar member retaining resiliency even after permanent deformation. The object is to mould an article without leaving any fin or flash. A plurality of male mould halves 20 are slidably fitted in bores 24 in a die plate 26 and female mould halves 22 are slidably fitted in bores 30 in a die plate 32. Between the mould halves in both plates and the cover plates 28, 34 are spool-shaped back-up members 72. The die plates 26, 32 are accurately aligned by dowels 50 and are fitted with handles.to enable them to be lifted in and out of the press and separated from one another. Each male mould half 20, Fig. 11, tapers to a die 90, and formed in the tapering surface is an annular shoulder 94. Each female mould half 22 projects beyond the die plate 32, tapering to an annular surface 106, and has a recess 102 which forms the mould cavity. 94 and 106 are the parting surfaces between the mould halves. 94, being wider than 106, projects inwards to form the edge or lip of the finished article, Fig. 13. All the parting surfaces in each die half must be accurately aligned, but the need for careful machining for this is obviated by the hack-up members 72, which when first fitted are slightly oversize and are deformed by the pressure of the initial moulding operations to the exact length required for accurate alignment of the parting surfaces. The cross-section and material of the back-up members are such as to give them the correct deformation, the latter being a metal with a modulus of elasticity less than 20 x 10<6> lb. per sq. in., e.g, brass, bronze or aluminium. The spool-shaped back-up members may be plain-walled, as shown, or they may be corrugated. The deformability of the back-up members enables them to yield if excessive local pressures arise, due, e.g., to hand particles in the moulding material, so guarding against crushing of the parting surfaces. The back-up members are easily replaceable. Before the moulding operation an excess of material over the amount required for the size of the article is placed in each recess 102. As the die 90 enters the recess, material M, Fig. 13, is squeezed out between the parting surfaces, which are narrow enough for all the material to be displaced and no fin or flash formed.

Title: Improvements in gear shifting mechanism
IPC: F16H63/02
Filed: 1935-05-20
Abstract: 457,179. Controlling change speed gearing. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. May 20, 1935, No. 29067/36. Convention date, May 21, 1934. Divided out of 457,108. [Class 80 (ii)] An electro-pneumatic actuator 220 for a gear-shift lever 14 is rendered operative by an electric switch 274, which is closed by disengagement of the main-clutch 12, such disengagement being effected by depressing the usual pedal 240, or by release of the vehicle accelerator to open a valve 36 and energize a vacuum motor 32, leading to the engine inlet pipe 26. The gear-actuator 220, also energized by enginesuction, is the same as that described in Specification 457,108 comprising a doubleacting gear-establishing motor and an integral single-acting cross-shift diaphragm motor, which latter acts against a permanent spring bias to swing the actuator laterally about its pivotal mounting 222 into the plane for selecting low-speed and reverse. The control valve-unit 24, integral with the actuator, is also the same as that in the above-mentioned Specification, with the exception that three electric solenoids directly control the valves. The circuits of the three solenoids are completed through the clutch-switch 274 and a manual preselector switch 74, comprising a miniature lever the movements of which simulate those of the main lever 14, as in the above-mentioned Specification. Control of the two solenoids controlling the gear-establishing motor only, can also be effected by a two-way switch, operated by rocking a treadle 34, which corresponds to the mechanical treadle in the above-mentioned Specification. The clutch-switch is arranged to keep the gear-shift actuator 220 loaded until after the main-clutch 12 has engaged sufficiently to apply a torque to the gears to facilitate the change. Further to assist this action, a checkvalve 276 may be arranged in the suction-inlet to the gear-shift actuator, or the size of the conduit 248 may be such as to render the checkvalve unnecessary. The clutch-motor 32 is more fully described in Specifications 412,184 and 443,718. Specification 442,128 also is referred to. The Specification as open to inspection under Sect. 91 included also the whole of the subjectmatter of Specification 457,108. This subjectmatter does not appear in the Specification as accepted.
