Title: Suspension systems for motor-vehicles having more than four wheels
IPC: B60G5/01
Filed: 1946-03-09
Abstract: 621,193. Motor vehicles. TRESILIAN, S. S. March 9, 1946, No. 23916/47. Divided out of 619,127. [Class 79 (iv)] A vehicle having more than four ground-engaging wheels in which the wheels are arranged in pairs on parallel ,axes, comprises one or more pairs of rear driving wheels driven through a differential and hub reduction gears, the remainder of the wheels being, differentially steered and incorporating brakes, torque arms associated with the reaction members of the speed reduction gears of the driven wheels and connected to the chassis frame to apply upward forces thereto during acceleration to combat dipping of the vehicle's rear, and torque arms associated with the brake reaction members of the forward steerable wheels and connected to the chassis frame to apply an upward force thereto during braking to counteract dipping of the front of the vehicle. As shown the vehicle has six pairs of wheels the rear two pairs 46 of which are driven through differential gears 56 and hub reduction gears 23a. Each hub has an extension 51 rotatably mounted in the axle casing and a torque arm 33a which is connected by a resilient leg 49 to the vehicle chassis. When accelerating the torque transmitted to the hub tends to lift the chassis at the rear, counteracting the normal tendency for it to dip.. The front wheels 47 and 48 are differentially steered through ganged worm drives 53 from the steering box 34 and the wheels 47 have torque arms connected to the chassis through resilient legs 49 so that when the vehicle is braked the torque experienced by the arms tends to lift the chassis thus counteracting the normal tendency for the vehicle's nose to dip. The centre pairs of wheels 48 are supported by their legs .49 in a conventional manner, and these wheels are not braked by the foot pedal, but are connected to the-hand brake. The arrangement is particularly suitable for double decker omnibuses and permits the use of a greater number of smaller wheels and hence a lower centre of gravity and smaller turning circle.

Patent GB-418251-A (GB)
Title: Improvements in or relating to electric discharge devices
IPC: H01J61/34
Filed: 1933-08-30
Abstract: 418,251. Discharge apparatus. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, PEARCE, A. G., and RYDE, J. W., c/o General Electric Co., Wembley, Middlesex. Aug. 30, 1933, Nos. 24080/33 and 2490/34. [Class 39 (i).] A discharge device is supported at one or more points within a surrounding envelope by spring supporting members interposed between the envelope and one or more members projecting from the tube, said spring supporting members being such that their resistance to displacement increases with displacement at an increasing rate. The springs are preferably leaf springs whose effective length decreases with increase of displacement, and are sufficiently resilient at small displacements to prevent damage to the leading-in wires or seals, while being stiff enough to prevent the tube being brought into contact with the outer envelope by sudden jars. In Fig. 2 the steel leaf spring 1<1> is secured at each end to a plate 4<1> by ears 3<1>, 3<1>1 and prevented from twisting by half holes at the ends fitting under a bolt 8 which serves to secure the plate 4<1> to a similar plate and spring which completes the supporting member. Leading-in wires 12, 12<1> are clamped between the plates and welded to lugs 6, 6<1>. A conductor welded to the member 7 passes to the other end of the tube and prevents longitudinal movement. In a modification shown in Fig. 3, two springs are arranged back to back curving away from each other, and four such pairs are arranged 90‹ apart and secured to a member 4 clamped about the leading-in wires 12, 121. Clips 18-21 enable the stiffness of the springs to be adjusted. As the displacement increases the springs roll and slide upon the walls of the envelope and their effective length decreases. The springs may be tapered towards their free ends to increase the effect. If it is desired to obtain a discontinuous variation the clips 18-31 may be arranged loosely on the springs so that the effective length is suddenly decreased when the clips tighten upon the springs. Alternatively the springs may be backed by one or more shorter springs. The springs may be of spring steel or of material bearing the Registered Trade Mark "Monel."

Title: Austenitic iron-base alloy
IPC: C22C38/38
Filed: 1955-08-24
Abstract: An iron-base casting is made by preparing an iron-base melt containing Cr 10-30 per cent and Mn 10-20 per cent, subjecting the melt to a pressure of at least one atmosphere above ambient, preferably in an inert gas, alloying the melt under this pressure with N in amount from 0.3 to 1.0 per cent till the ratio Cr : N is between 70 and 25, casting the melt into a mould while still under pressure and abstracting heat sufficiently rapidly to cause solidification without substantial ebullition of gas, the relative amounts of austenite formers and ferrite formers in the alloy being such as to result in a substantially completely austenitic structure. The N may be added as such or may be derived from cyanides, cyanamides, ammonia or nitrogen-bearing alloys with Fe or Fe-Cr.  The alloy may also contain Si up to 3 per cent, Ni up to 8 per cent, W or Mo up to 6 per cent and V up to 0.5 per cent.

Title: Improvements in means and method for controlling or preventing oscillations in vacuum tube circuits
IPC: H03F1/36
Filed: 1925-09-30
Abstract: 241,185. Thompson Manufacturing Co., R. E., (Assignees of Phelps, B.). Oct. 30, 1924, [Convention date]. Thermionic amplifiers and detectors. -To counteract the back-coupling set up across the internal electrodes of a valve amplifier, advantage is taken of the opposing potentials developed across a pure ohmic resistance or an inductive reactance inserted between the high and low tension batteries, i.e. in a part of the circuit common to both the input and output paths. As shown in Fig. 1, the potential gradient across the resistance 13 between the fixed connection to the filament battery and the adjustable grid-tapping increases as the plate current increases. The corresponding drop in grid potential therefore curbs the plate current and tends to oppose the conditions leading to self-oscillation. In Fig. 3, the resistances 18<1> and 19<1> serve a similar purpose with regard to the high-frequency amplifiers 14<1>, 15<1>. Here however the direct-current supply to the plates flows through chokes 25, 26, and does not impress any steady bias upon the grid, whilst the radio frequencies pass through the condensers 29, 30 and resistances 18<1>, 19<1>, and impart transient voltage variations which check the tendency to self-oscillation. In Fig. 4 the curbing back-voltage across the stabilizing resistance 33 is derived from the grid current flowing in the detector valve 37 instead of from the plate current as before. The windings of the intervalve coupling transformer 34 are adjusted to give the _proper neutralizing direction of flow in the resistance 33. A reflex circuit is also described in which two stages of combined high and low frequency amplification are employed, the plate current from the second valve being passed through a single curbing resistance inserted in the grid circuit of the first but serving to stabilize both valves. Specification 172,758 and 220,727 are referred to.

Title: Improvements relating to magnetic amplifiers
IPC: H03F9/02
Filed: 1948-09-17
Abstract: 670,081. Magnetic amplifiers. MONTGREMIER, P. A. DE, and GACHET, P. Sept. 17, 1948, No. 24479/48. [A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 13, 1949.] Class 40 (iv). [Also in Group XXXVII] In a magnetic amplifier, two back-to-back connected transductors Tl, T2 each comprise a main winding 6 and a reaction winding 12 which is energized by rectified current from a voltage tapping on the main winding associated with the other transductor. As shown, in each transductor, the main winding is connected in series with a bridge rectifier 8 to a common alternating current supply, while the reaction winding is energized from a variable tap 15 on the main winding of the other transductor through a condenser 16 and a rectifier 14. The transductors are normally balanced, but the application of direct current potential to seriesconnected control windings 9 causes the inductances of the two transductors to change in opposite senses according to the applied polarity. This unbalance is enhanced by a change in current in the reaction windings and by the establishment of a direct current in series-connected windings 18 due to the difference in the rectified main-winding currents passing through resistances 17. A variable resistance 20 is provided to control the intensity of the current in windings 18. Resistances 17 are parts of the output circuit of the amplifier and may be, for example, exciting windings of a motor so that the direction of rotation is controlled by the polarity of the control voltage. In a modification, Fig. 2 (not shown), the rectifiers 8 are transformer-coupled in series with the main windings and the resistance 20 is omitted, windings 18 being energized from various taps on the resistances 17.

Abstract: 1,214,464. A.C./D.C. static converters. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 9 Feb., 1968 [14 Feb., 1967; 26 May, 1967], Nos. 7104/67 and 24532/67. Heading H2F. An A.C/D.C. converter (voltage multiplier) comprises. an even number of similarly-poled capacitor-shunted rectifier stages connected in series between a pair of D.C. output terminals, and A.C. input terminals connected to intermediate points on the rectifier stack in such a manner than in operation half of the stages are driven in anti-phase to the other half, at least one of the input terminals being connected to the rectifier stack through a capacitor. Thereby the phasing of the ripple of the two halves of the converter are effectively interlaced giving an output ripple which is at twice the supply frequency but is half the amplitude compared with that obtained with an arrangement wherein all the stages are driven in the same phase for instance as illustrated in Fig. 5 (not shown). As shown, Fig. 6, each stage comprises two similar pairs of series-connected rectifiers each pair shunted by a respective capacitor and one input terminal being connected through C S1  to the stack. The lower half of the stack is driven in anti-phase to the upper half. Each stage may alternatively comprise a basic unit as shown, Fig. 4, wherein the capacitors e.g. C 1 , C 2  (Fig. 6) are replaced by a single capacitor C e . Since, assuming C S1  is charged, charging current for C 1 , C 2  via C S1  R 2A  and R 1B  flows during one half cycle and current to recharge C S1  flows via R 1A  and R 2B  during the other half cycle, the junction between C 1 C 2  and R 1A  R 2B  can be omitted as currents flowing in C 1 C 2  and those flowing in R 1A  R 2B  cannot flow at the same time. Polyphase and bi-phase centre-tapped transformer arrangements of the basic circuit of Fig. 6 are envisaged as also are series resonant LC circuits in the input phase lines.

Abstract: 988,975. Moulding hollow articles. IMPERIAL CHEMICAL INDUSTRIES Ltd. March 25, 1964 [June 20, 1963], No. 24582/63. Heading B5A. In a blow moulding process, in which part of the mould cavity wall is formed by at least two intersecting planes, the sheet material is urged towards said part of the mould by a plunger which contacts only the small area of the sheet which will be formed by said mould part. In this way undue thinning of the sheet in this region is avoided. In the embodiment shown in the Figures, a cover, for use with a light fitting, having a re-entrant portion (see Fig. 4, not shown) is formed by clamping a heat softened sheet of thermoplastic material 15 against a base 5 by a female mould, comprising a box-like member 1 clamped by clips 4 to a two-piece base frame 2, and blowing the sheet into the mould. The base 5 carries four piston and cylinder mechanisms 7, each of which carries a wedge 9 of e.g. rubber, the wedges being biased to a retracted position by e.g. springs 13. In operation, air is introduced at a relatively low pressure through aperture 6 to blow the sheet partly into the mould, the pistons 7 then being actuated to push the appropriate portions of the sheet material into the corners of the mould. Increased air pressure is then applied to the sheet to completely shape it against the mould wall, the mould being disassembled and then withdrawn and the formed article removed when the sheet has sufficiently cooled.

The modulating microphone may be placed across the aerial inductance or elsewhere. In a modified arrangement, simple alternating current is fed across an auto-transformer to two valves arranged symmetrically in opposition, so that each half-cycle from the source is utilized for power transmission to the aerial. Continuous-wave signals from such a set may be received without ticker or heterodyning.
