Title: Improvements in automatic and semi-automatic telephone systems
IPC: H04Q3/00
Filed: 1925-06-20
Abstract: 260,015. Standard Telephones & Cables, Ltd., (formerly Western Electric Co., Ltd.), and Gould, J. R. June 20, 1925. Automatic and semi-automatic exchange systems. - A rotary connector serving ordinary lines as well as lines to private branch exchanges and which does not hunt unless the first line of a group is dialled has a two-step busy relay G which is fully energized during hunting and pre. vents further impulses from reaching the rotary magnet. The relay HS which decides whether hunting shall take place acts over a second wind.. ing as a stepping relay to the rotary magnet. The busy signal is given by connecting the ground end of the line relay A to interrupted tone and battery BF, synchronous impulses being delivered from BH to a second winding of the release relay B. The connector has an extra wiper PI co-operating with a bank in which ordinary lines and last lines are dead, first lines connected to battery and intermediate lines strapped to the regular test terminals. The test wiper P is a bridging wiper. Numerical selection, busy test and signal. The tens digit is repeated by relay A to magnet V and relay C which maintains the vertical circuit after springs H change over and at the end of the digit switches over to the rotary magnet R and relay E. Relay E during the units digit connects the lower winding of relay G to the test wiper P and re-energizes relay C. If the line is busy, relay G on the relapse of relay E attracts all its armatures and locks up in a circuit independent of relay E, and, if the line is not the first of a group relay C falls back, sends the busy signal and locks relay G to a local ground. Hunting. If the busy line is the first of a group, relay HS pulls up over wiper P1 and reenergizes the rotary magnet and relay E which holds up relay C, disconnects the upper winding of relay HS and connects the lower winding to the wiper P1 over the interrupter contact of the rotary magnet. Relay HS falls back and releases the magnet at the end of the stroke and pulls up again to re-energize it if the line is busy. If all the lines are busy relay HS is not reenergized on the last terminals (the last PI terminal being dead) but relay G holds up. Relays E, C fall back in succession and the busy signal is sent as before. Ringing current and signal. When an idle line is found, relay G falls back (if the line dialled is idle relay G is not energized) and relay H which is connected to the test wiper by the relapse of relay E pulls up sluggishly in two steps and sends out ringing current from R, ringing signal leaking back over QA. When the PBX replies, relay F extends the loop to the reversing relay D. Release and statistical metering. The relapse of relays A, B at any stage releases any operated relays and energizes the release magnet Z in series with a common alarm relay which may operate a traffic meter.

Abstract: 704,267. Gauging apparatus. SOC. GENEVOISE D'INSTRUMENTS DE PHYSIQUE. July 6, 1951 [Aug. 10, 1950], No. 16071/51. Class 106 (2). [Also in Group XX] An optical gauging apparatus of the projection type for examining cross sections of a complex object, such as a gas turbine blade, comprises a screen 3 on which is projected by means of a lens 2, an image of the cross section of the testpiece 6 along an optical axis AA via mirrors 4, 5. The test-piece is held in an adjustable clamp which may be raised or lowered and which is provided with indicating means 15, 16 so that a precisely located cross section may be examined. A plurality of lamps 8 are arranged in a holder 17 in a ring formation surrounding the test-piece 6. A tubular shield is also mounted in the holder 17 with its lower edge in line with the optical axis of the filament of the lamps 8 and associated condensers 9. The tubular 'shield 18 cuts off direct light from the lamps 8 above the line 11 whilst permitting the light reflected by the surface of the test-piece below the edge of the shield to be transmitted through its centre. The test-piece appears on the screen in the form shown in Fig. 2 in which the area 19 is dark and corresponds to the cross section along the line 11. The remaining area of the test-piece below the line 11 appears light 21 due to the reflected lights passing through the centre of the shield 18. The lens 2 is also made with a central aperture through which part of the test-piece may project in order that the focal length of the lens shall not limit the length of the test-piece which is to be measured. In order to give effective contrast between the areas 19 and 21 on the screen 3 the test-piece is coated with a light reflecting substance such as magnesium oxide. In a modification shown in Fig. 3 the tubular shield member 18 may be replaced by a plane member 25 located between the lenses 24, 26 so as to produce a sharp line of light on the test-piece 6 in similar manner to the tubular shield 18.

Abstract: 568,123. Valve relay circuits; directive wireless systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., COCKERELL, C. S., and CUFFLIN, M. H. Dec. 15, 1941, No. 16182. [Class 40 (v)] In a radio receiver for short pulse signals (e.g. in direction finding), the pulses are shortened in duration and thus rendered separable by passing them through a differentiating circuit, followed by a rectifier. As shown, the pulses are amplified in the valve V<1> and passed to a circuit RC which is so proportioned that the voltage across R represents the time differential of the anode voltage of the valve V<1>. The differentiated pulses are amplified in the valve V<11> and their negative portions are removed by the rectifier D, the output being taken across the resistance R<11>. Two or more differentiating stages may be used. An inter-valve transformer having a low inductance and a good high-frequency response may be used as the differentiating circuit instead of the combination RC.

Inventor: MCLEAN DONALD HENRY
IPC: C07C37/14
Filed: 1948-06-16
Abstract: Higher poly-tert.-butyl phenol or cresols are separated from lower tert.-butylated phenol or cresols in the crude reaction mixture resulting from the alkylation of phenol or a cresol with isobutylene or a butyl halide in the presence of an alkylation catalyst by a process in which the crude mixture is cooled to a temperature at which the higher poly-tert.-butyl phenol or cresols precipitate out, and these are then separated, and washed to remove catalyst.  The process may be operated continuously.  In the examples (1) phenol is alkylated with a C4 refinery cut containing isobutylene, in the presence of sulphuric acid, and the tri-tert.-butylphenol separated at 40 DEG  C., (2 and 3), p-cresol is similarly alkylated with the C4 refinery cut and di-tert.-butyl-p-cresol separated at room temperature.

Filed: 1973-04-09
Abstract: 1400104 Fluid-pressure servomotor systems CONTROLS CO OF AMERICA 9 April 1973 [31 July 1972] 16861/73 Heading G3P [Also in Divisions F2 and F4] A refrigeration system control valve assembly comprises a first valve 16 in a duct between the condenser C and the evaporator E and a second valve 40 in a duct 92 between the evaporator E and the compressor P. The first valve 16 regulates flow to the evaporators in accordance with temperature and pressure in the duct 92 and the second valve 40 regulates flow from the evaporator in accordance with the pressure and/or temperature of the refrigerant in the valve assembly body. The thermostatic expansion valve 16 is opened against the action of a spring 18 by pushrods 24, 26 connected to a diaphragm 28, a space 30 in the rod 26 communicating with a charged space 32 above the diaphragm, whereby the actuation of valve 16 is influenced by the temperature and pressure surrounding the rod 26 at the evaporator outlet. The valve 40 has outlet ports 82 closable by a piston 54 acted on by an adjustable spring and bellows arrangement 64, the sealed space within the bellows being at atmospheric pressure and leakage being allowed between the piston 54 and cylinder 50 through a port 94 in the piston skirt. When the pressure surrounding the bellows exceeds the adjusted value, the bellows contract and relieve a pin 76 thereby allowing a spring 88 to open a pilot valve 86. The reduction in pressure in the pilot chamber 90 causes the piston 54 to move against the action of a spring 98 to bring ports 80 into alignment with the ports 82 to allow full fluid flow through the valve. In a second embodiment, Fig.3 (not shown), the evaporator pressure regulator valve 40 is replaced by a wax-element temperature responsive valve. In a further embodiment, Fig.5 (not shown), a wax-element butterfly valve is provided. The valve may be provided with a drier-receiver, Fig.8 (not shown), may be externally equalized by providing a connection between the chamber on the underside of the diaphragm and a point downstream of the valve 40 and may also include a by-pass around the valve 40.
