Title: Polarised vibration relay
IPC: H01H50/76
Filed: 1949-03-28
Abstract: 657,882. Electromagnetic relays. KRIZIK, NARODNI PODNIK. March 28, 1949, No. 8390. Convention date, April 23, 1948. [Class 38(v)] In a polarized vibratory relay adapted for operation by A.C. and wherein a moving contact member moves between two " fixed " contacts and engages one of them when the relay is de-energized, the two moving contacts, or alternatively the two " fixed " contacts, are mounted on springs of different dimensions, shape or material, to compensate for the lack of symmetry of the device and produce equal periods of closing time for the two contacts. To produce this effect the spring 5 of a normally-closed pair of contacts is made more yielding than the other spring 6.

Title: Improvements in or relating to amplifier circuit arrangements
IPC: H03J3/06
Filed: 1932-03-21
Abstract: 380,377. Valve amplifying circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London. -(Assignees of Farnham, P. O. ; 104, Elcock Avenue, Boonton, New Jersey, U.S.A.) March 21, 1932, No. 8401. Convention date, March 19, 1931. [Class 40 (v).] In a tuned high-frequency amplifier employing one or more dynatron or negative-resistance valve stages, means are provided (1) for maintaining stability and substantial uniformity of gain over the tuning range, and (2) for maintaining stability when volume is controlled by regulating the bias on an input grid. Fig. 4 shows a two-stage amplifier employing screengrid valves V1, V2 as dynatrons, and with a tuned input circuit L, C and tuned intervalve and output circuits L2, C2. When the tuned circuits are adjusted over the tuning range, their impedance as viewed from the platecathode terminals of the valve is altered, and the gain (which depends on the ratio of the external impedance to the internal impedance) is also altered. To overcome this, the tuned circuit L2, C2 is connected to the plate through a small condenser Cm, and is shunted by a series combination of a coil L1, resistance R1 and large capacity C1. This has the effect of maintaining the external impedance substantially constant during tuning, and so effects the object (1). Self-oscillation is also prevented, as the external impedance cannot become greater than the internal impedance. The shunt circuit L1, R1, C1 may be replaced by a parallel combination of inductance and capacity in series with a resistance, Fig. 8 (not shown). In Fig. 7, the external impedance is kept constant, by linking the tuning condenser C2 to a variable resistance R in the tuned plate circuit ; whilst in another modification; Fig. 10 (not shown), the tuning condenser is linked to a variable self-biasing resistance in the control grid circuit. Referring to the second object of the invention, this is attained in the circuit of Fig. 4 by interposing resistances R in the plate-supply circuits. As volume is increased by reducing control grid bias Ec, the resistance R (owing to the negative characteristic of the plate circuit) adds to the plate voltage and so maintains stability. Where two stages are employed, a single resistance R may be employed, with a variable tap 10 connected to the supply source. Instead of employing the resistance R, the grid-bias control Ec may be linked mechanically to the plate-voltage control EB in such a way that EB increases as Ec decreases, Fig. 11 (not shown). Stability under volume control may also be effected by interposing a resistance in the high-voltage screengrid circuit, Fig. 9 (not shown). The Specification includes sets of characteristic curves of the valves, and other curves showing (a) substantial uniformity of gain over the tuning range, (b) that the circuit is more selective than the normal tuned amplifier, and (c) that selectivity increases at high gain ratios.

Filed: 1966-02-28
Abstract: 1,139,070. Injection moulding machines. NEW BRITAIN MACHINE CO. 28 Feb., 1966 [14 April, 1965], No. 8616/66. Heading B5A. In an injection moulding machine having an axially reciprocable feed-screw 13, the injection and retraction movements of the screw are controlled by means of an hydraulic piston 23 and cylinder 24 to ensure optimum quality in the moulded products. During the injection stroke a cam 25 constituted by plates 50 and follower 26 effect a gradual build-up of the rate of advance of the screw 13, followed by a slow final filling phase. During retraction the bleed of fluid from cylinder 24 is controlled by a cam constituted by plates 60 and follower 26<SP>1</SP> in such a way as to compensate for the shortening length of screw effecting plasticizing of the material. The cam plates 50 and 60 are displaced bodily with the screw 13 and are adjustably clamped together so as to give variable profiles. The two cams are mounted for sliding movement on a shaft 29 which can be pivoted by means of a crank 62 and hydraulic actuator 41. Such pivotal movement effects changeover between the cam and cam follower assemblies and takes place at the same time as a valve 39 is changed over. Valve 39 is operable by solenoids 40, 40<SP>1</SP> and determines whether pressure on piston 23 is controlled by valves 33, 38 or by a valve 34. Valve 33 is effective during injection and is adjusted by cam 25 through a pivoted lever 30. During screw return hydraulic fluid is free to flow through a check valve 33<SP>1</SP> and flow is controlled by valve 34 which is adjusted by cam plates 60 through a lever 61 connected to a rack 35 and pinion 36.
