Title: Improvements in or relating to time constant control circuits for radio telephone and similar systems
Inventor: COLCHESTER CHRISTOPHER DERING
IPC: H03G7/02
Filed: 1949-02-24
Abstract: 663,231. Automatic volume control. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Nov. 11, 1949 [Feb. 24, 1949], No. 5115/49. Class 40 (iv). [Also in Group XL (c)] In a time-constant control circuit, arrangement of the type which includes a rectifier (12) and condenser (6) network and wherein the charge on the condenser (6) controls the current through a valve (4) to determine the loss or gain in a signal channel, the cathode (9) of the valve is grounded through an impedance (13) of the same order as the internal impedance of the valve, a resistance (14) is connected between the control grid (5) and cathode (9) of the valve to determine the approximate value of the time constant, and the control of the signal channel depends upon the potential of the cathode with respect to ground. As shown, a variable attenuator 1 in a speech channel is controlled and the valve 4 is preferably a pentode or tetrode with an amplification factor of about 1000. Preferably the cathode potential of valve 4 is applied to the control grid of another value (not shown), the anode current of which controls the attenuator. The grid resistor 14 has a value of about one megohm, and grid bias is normally applied, but is removed by the opening of contacts 11 in the absence of speech by a control (not shown). Speech input is applied through the rectifier 12 to the junction of resistor 15 and contacts 11. Guard electrodes are provided for the condenser 6 and contacts 11 and are connected to the cathode 9. The provision of resistor 13 causes the impedance to ground at the control grid to be multiplied by a factor of the same order as the amplification factor of the valve and the resistor 14 may therefore be added so that the rate of discharge of condenser 6 is no longer dependent on stray leakage and is definitely controlled.

IPC: H01J43/20
Filed: 1954-02-25
Abstract: 777,457. Electron multipliers; mass spectrometers; cathode materials. BENDIX AVIATION CORPORATION. Feb. 25, 1954, No. 5595/54. Class 39(1). An electron multiplier, particularly for use with a time-or-flight mass spectrometer, comprises two series of secondarily emissive plates 70-82 and 84-96 disposed back-to-back with electric and magnetic fields so arranged as to direct the secondary electrons from the last plate 82 of the first series to the first plate 84 of the second series, and an electrode 106 in the form of a grid interposed in the path of the electrons from the first series to the second series which shields the electric fields established between the plates of the second series from the electron fields established between the plates of the first series. The plate 70 has a width greater than that of any of the other plates. The electrode 106 is at a potential intermediate between that of the plate 82 and the plate 84. The successive plates in each series are laterally contiguous and relatively displaced perpendicularly to their planes and are at potentials so correlated with their respective distances from common electrodes 40, 108, preferably at ground potential, as to produce substantially equal electric accelerating fields between any two successive plates. More than one of the plates 70, 72, 74 of the first series are arranged to receive primary charged or uncharged particles, e.g. ions, neutrons, atoms and electrons, through the slot 42 and those plates 72, 74 which receive both primary particles and secondary electrons are arranged to yield a multiplication factor of about unity, whereas the following plates yield a multiplication factor of about two. The plates of the first and second series can be made from a beryllium-copper alloy having approximately 2 per cent of beryllium. The primary particles passing through the slot 42 can be ions produced in bunches by a mass spectrometer of the timeof-flight type substantially as described in Specification 767,527 and the electrons emitted by the last plate 96 are collected by the electrode 110 connected to an oscilloscope 46. Specification 727,683 also is referred to.

Abstract: 832,593. Cam mechanism. ALADDIN INDUSTRIES Inc. Feb. 24, 1958 [March 27, 1957], No. 5909/58. Class 80 (3). [Also in Group XL (c)] A radio tuning element is connected to a cam follower driven by a cam secured to a rotatable shaft, the cam follower being biased by a spring, the other end of which is connected to the follower of a second cam secured to the shaft so that the spring strength is kept constant. Fig. 1 shows four tuning elements 12 which may comprise linearly movable coils, sleeves, cores or slugs. The tuning elements 12 are ganged together so as to be driven to a number of pre-set positions by a rotatable shaft 14. The pre-set positions are governed by a detent cam 20 having peripheral valleys which are engageable by a spring-loaded ball 18. Each tuning element 12 is controlled by a cam 26 having adjustable lobes 30. The cam follower 36 associated with the tuning element 12 tuning the most critical circuit is rigidly coupled to a rocker arm 38, pivoted on balls 58, 60. The other cam followers 44 are attached to resilient arms 46 also coupled to the rocker 38. The cam followers 44, 36 are biased by a spring 48 rigidly attached to the rocker 38 by an arm 50. The other end of the spring 48 is connected to a cam follower 54 controlled by an equalizing cam 52 the shape of which is inversely related to the tuning cam 26 so that the strength of spring 48 is maintained constant.

Title: Improvements in, or relating to, capsules
IPC: B65D41/10
Filed: 1944-03-31
Abstract: 589,862. Bottle capsules. BETTS & CO., Ltd., and MENHENEOTT, F. M. March 31, 1944, No. 5977. [Class 125 (iii)] [Also in Group V] A corrugated capsule of a non-metallic plastic material, and of the type intended to be fitted over a mouth of a bottle, is made by coating a mandrel, having a corrugated surface 5, with the plastic material in the fluid state, allowing the plastic to set, and then removing the mandrel. The mandrel's corrugated surface may be generally cylindrical or of frusto-conical form, the depth of the corrugations decreasing from one end to the other. The coating may be effected by dipping the mandrel to cover one end face and the corrugated surface. Before dipping, the mandrel is coated with a lubricant (e,g., petroleum jelly) which is incompatible with the fluid plastic material and which is later removed from the capsule by means of a degreasing agent such as carbon tetrachloride. The capsule rim is coated (e.g., by dipping) with a thermoplastic or cold-setting cement, such as a mixture of ester gum, nitro cotton, plasticizer, acetone and methylated spirit. The non- metallic plastic material may be a cellulose derivative, a synthetic or natural resin or gum, shellac, rubber, gelatine, or other gelatinous compounds such as alginates. An example of a fluid plastic material is a solution of a plasticized nitrocellulose or cellulose acetate in acetone.
