Title: Improvements relating to electrical ramp generating circuits
Inventor: ETHERIDGE JAMES EDWARD
IPC: H03K4/58
Filed: 1965-09-15
Abstract: 1,145,693. Transistor sawtooth circuits. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. 15 Sept., 1966 [15 Sept., 1965], No. 39341/65. Heading H3T. In a ramp generator, a capacitance is charged via a bootstrap circuit including a differential amplifier responsive to the difference between the voltage across the capacitance and a reference voltage controlled by an impedance in dependence on the amplifier output. As described, capacitor C1 charges via resistor R1 the voltage across the capacitor being passed by emitter followers TR2, TR3 to a comparator circuit TR4, TR5, the output of which is passed by emitter followers TR6, TR7 to the upper end of resistor R1. Transistor TR5 of the comparator is fed from the output of transistor TR7 via a Zener diode ZD1, potentiometer RV1 being adjusted so that the amplifier has unity gain, giving a linear charge of capacitor C1 Alternatively RV1 may be set to give an increasing or decreasing gradient. The charging current is regularly blocked by conduction of a switching transistor TR1 under control of an astable multivibrator TR8, TR9 so that a stepped ramp waveform is available at Vc. In Fig. 3 (not shown) the circuit is adapted for control of an electro-static precipitator, a constant current transistor (TR12) being connected across C1 and made conductive by a monostable circuit controlled by signals from the precipitator. Manually operated contacts are included in the charging circuit to provide a rapid increase of charge when required.

Title: A process for the gasification of liquid fuels
IPC: C01B3/32
Filed: 1957-12-18
Abstract: 875,136. Gasifying liquid fuel. RUMMEL, R. Dec. 18, 1957 [Dec. 19, 1956], No. 39358/57. Drawings to Specification. Class 55 (2). In a process for gasifying a liquid fuel with gasifying agents containing free oxygen the gas generated after it has given off part of its sensible heat is washed with a portion of the liquid fuel, the portion of the liquid fuel used for washing the gas being subsequently gasified in the process. The gasification may be effected in a circulating bath of molten slag and the gas leaving the slag bath may be carburetted by injecting liquid fuel into the gas thereby absorbing some of the sensible heat of the gas. Alternatively the hot gas, before washing, may be passed through a waste-heat boiler or other heat recovery apparatus to reduce its temperature. In a modification the liquid fuel which has been used for washing the gas produced is distilled to remove absorbed gases before it is gasified.

Abstract: 861,032. Incandescent electric projection lamps. SYLVANIA ELECTRIC PRODUCTS Inc. Dec. 8, 1958 [Dec. 9, 1957 (2); Jan. 9, 1958], No. 39557/58. Class 39 (2). [Also in Group XX]. In an incandescent projection lamp having a sealed light transmitting bulb and a filament and reflector mounted within the bulb on a common header, the reflector is in the form of a concave shell with a substantially circular perimeter cut off along two generally parallel chords at opposite ends of the diameter and the filament is an elongated filament mounted with its longitudinal axis substantially parallel to the diameter and at right angles to the chords. The reflector is carried by the filament support so that the two can be arranged in correct relationship before the filament mount is sealed into the bulb. The reflector is preferably made of pressed metal e.g. pressed and polished copper coated with nickel and then silvered. Alternatively, a curved glass plate having a reflecting coating of silver or aluminium deposited on the concave surface e.g. by evaporation or condensation in a vacuum may be used. In one form, four lead-in wires 9, 11, Fig. 2, and 10, 12 (not shown) are sealed into a glass disc 4. Support wires, 27, 29 and 28, 30 (not shown) are gelded to short wires 23, 25 and 24, 26 (not shown) on the back of the reflector 17, the wires 27, 28 being welded to the wires 9, 10 and the wires 29, 30 being brought together and welded to a cross wire 31 extending between the wires 11, 12. The filament 3 is of non-sag construction and is connected at the ends by wires 33 (not shown) and 34 spaced apart by transverse, wires carried by an insulating glass bead and welded to the lower ends of the wires 27, 28. A metal cap 43 having an outwardly projecting part 45 covering the sealed exhaust tube and provided with a keyway for centering the lamp is connected to the neck 5 of the bulb. The cap has holes through which wires 9-12 pass, being insulated from the cap by small glass projections on the disc 4. The reflector may be spherical or ellipsoidal. The lamp is filled with nitrogen at a pressure of about 100‹ millimetres of mercury and the upper part of the bulb is provided with a coating 8 of coloured or black enamel glaze. In a modified form, the filament is supported by two wires passing through a ceramic button mounted in a slot in the reflector, the assembly being attached to the header of the lamp by four support wires, two of which act as lead-in wires, all four wires being welded to contact pins in the header. The ceramic button may be composed of 86% talc, 8% feldspar and 6% ball clay.

Title: Improvements in or relating to devices for detecting the presence of over-heated axle bearings in railway vehicles
IPC: B61K9/04
Filed: 1957-12-20
Abstract: 836,273. Detecting hot bearings in railway rolling stock. SIEMENS & HALSKE A.G. Dec. 20, 1957 [Jan. 10, 1957], No. 39762/57. Class 40 (3). In apparatus for detecting overheated axle bearings in railway vehicles, and adapted to be mounted alongside the railway track, a shutter 6 mounted on the lower end of a resilient rod 5 controls the exposure time of a radiation receiver 4 to heat rays 3 from a bearing 2 reflected on to the receiver 4 by a parabolic mirror 1. The resilient rod 5 is pivoted at its upper end 10, and is connected to a draw wire 9 to the armature of an electromagnet 7 which acts in opposition to a spring 8 which normally holds the rod 5 in its inoperative position with the shutter 6 against a damping abutment 15. The electromagnet 7 is energized by a device (not shown) actuated in response to the presence of a train wheel upon the track, so that the rod 5 is momentarily moved aside causing the lower end to oscillate about its junction with the wire 9 so that the shutter exposes and then covers the receiver 4 at least once. The signal gerierated by the receiver 4 during the first oscillation of the shutter 6 is amplified and fed to a discriminator which compares its amplitude with a predetermined value which may be dependent upon external temperature. If the predetermined value is exceeded a signal lamp 14 is switched on by a relay 13, an axle counter may be stopped or an axle marking device actuated.

The scale 12 may be coupled to means actuating the stacking device so that, in operation, the device is actuated to transfer a stack of slices to a conveyer 16 upon the registration of a predetermined weight by the scale. Alternatively the device may be actuated by a counter after a pre-selected number of slices has been discharged from the blade. This latter embodiment may be modified so that the counter permits weighing of a certain number of slices less than said pre-selected number and this weight is compared with that of a standard for the certain number of slices, there being feedback between the scale and the means 26 to adjust the slice thickness as required. In yet a further modification the weight of a certain number of slices is compared at pre-set intervals. A device may be provided for rejecting underweight stacks.
