Filed: 1958-04-11
Abstract: 892,816. Protective cut-out arrangements. ROTAX Ltd. July 10, 1959 [April 11, 1958], No. 11533/58. Class 38 (5). An arrangement for protecting a three-phase motor comprises a capacitor Y and a pair of resistors R1, R2 connected in series between two phases, a rectifier MR1 connected between the star point N of the motor and the point S between the resistors, and a relay RL1 connected across the rectifier. The values of the capacitor and resistors are such that under normal conditions S and N are equipotential points, but in the event of an open circuit, short-circuit, phase reversal or earth fault, a potential difference occurs between the points and the relay RL1 is operated. The rectifier may be a full-wave rectifier, Fig. 2 (not shown). If the supply is earthed, the capacitor Y may be connected to a terminal K1 so that an earth fault can be detected. The relay RL1 may close the circuit for a warning device or automatic control means.

Abstract: 1530136 Protecting gas detectors BRITISH GAS CORP 9 June 1976 [20 March 1975]  11690/75 Addition to 1447488 Headings G1B and G1N In a gas detector according to Parent Specification, the water-trap includes a valve which, if pressure is lost in the flow line, will either close the flow line or open a normally closed by-pass line to admit air to the flow line. In a first embodiment, Fig. 1, an abnormal depression of e.g. 12 in.w.g. in lines 22, 15 due to entry of water into a sampling probe 18, causes a diaphragm 73 to block the further progress of water by flexing against a seating 75. Photo-electric means 77, 78 responsive to the flexing of the diaphragm 73, provide a warning signal. Pressure in the line 15 may be released to relax the diaphragm 73, by the operation of the manual pressure relief valve 79. Alternatively, Figs. 2, 3, a branch pipe 81 teed into the line 22 communicates with a manometric valve 24b which will, under excessive depression, open, by transfer of mercury 82 into a chamber 84, to vent the line 22 to atmosphere. Electric conductors 88, 89 sense the withdrawal of the mercury 82 to provide a warning signal. Baffles may be provided in the chambers 84, 85 to prevent mercury from splashing into the ends 86, 87 of the by-pass pipe 81.

Title: Improvements in automatic stokers
IPC: F23K3/14
Filed: 1936-04-24
Abstract: 471,336. Screw-conveyers. PELTZ, G. M. April 24, 1936, No. 11705. Convention date, April 24, 1935. [Class 78 (i)] A domestic stoker installation comprises two screw-conveyers, one, 17, of which is arranged in an adjustable conduit 14 leading from a supply bin (not shown) to an intermediate chamber 9 and the other, 6, is arranged in a conduit 5 leading from the intermediate chamber to the furnace 1. The latter conduit may also serve as the combustionair supply to the furnace from a blower 30 as described in Specification 469,505. Flexibility of the conveyer 17 is provided by omitting the usual shaft portion of the screw. The two conveyers are driven from a common driving wheel 26 arranged around the intermediate chamber and driven from a motor 41 above such chamber. The wheel is provided with upper and lower bevel wheels 26a, 26b which engage bevels 24, 25 on'the ends of the conveyers.

Title: Improvements in or relating to fluid flow proportioning valves
IPC: G05D16/10
Filed: 1946-04-16
Abstract: 615,919. Fluid-actuated valves. BENDIX AVIATION CORPORATION. April 16,1946, No. 11716. Convention date, April 23, 1945. [Class 135] Apparatus for dividing a fluid stream into two, e.g. equal, streams or uniting two streams equally comprises a valve body 10, Fig. 2, having a main line 55 communicating through ports 74, 75, Figs. 3, 5, in a spring-loaded sleeve 58 and ducts 70, 71 with the ends 72, 73 of a cylinder 14 having a piston 15 formed with pairs of grooves 22, 23 and 24, 25 coacting respectively with grooves 16, 17 in the cylinder wall which are in open communication with branch lines 20, 21, Fig. 4. The ports 74, 75 in the sleeve 58 are controlled by a spring- loaded piston 63, the position of which depends upon the pressure in the line 55, and flow from the cylinder ends to the grooves 16, 17 is controlled by spring-loaded check valves 39, Fig. 5, and 49, Fig. 4, and in the reverse direction by check valves 27, 42. Leakage of fluid between the grooves 16 and 17 past the piston 15 is prevented by the fluid pressure in grooves 78, 79 communicating through bores 44, 31 respectively with the cylinder spaces 72, 73. When the apparatus functions to divide into equal parts a fluid stream entering the line 55, the pressure of the fluid presses back the piston 63, Fig. 3, to open the ports 74, 75 through which the fluid flows to the cylinder spaces 72, 73 and thence past the valves 39, 49 and the spaces 22a, Fig. 5, and 25a, Fig. 4, to the grooves 16, 17 and the branch lines 20, 21. If, e.g. the flow through the line 21 becomes too great, the pressure in the cylinder space 73 falls and the piston 15 moves to the right, thus increasing the space 22a and the flow through the groove 16 to the line 20, and reducing the space 25a and the flow through the groove 17 to the line 21. When the apparatus functions to unite the flows entering the valve body through the lines 20, 21, the fluid from these lines flows from the grooves 16, 17 into the grooves 23, 24 and thence past the valves 27, Fig. 4, and 42, Fig. 5, into the spaces 72, 73, and then via the ducts 70, 71 and the ports 74, 75 to the line 55. Differences in flow result in corresponding differences in the pressures in the spaces 72, 73 and movement of the piston to equalize the flow. The valve may be modified to produce unequal flows by making the ports 74, 75 of unequal size, forming the piston 15 with ends of unequal area, or loading one end of the piston by a light spring. Specification 599,012 is referred to.

Title: Preparation of pencillin salts
IPC: C07D499/16
Filed: 1945-05-12
Abstract: Penicillin salts are obtained from an alkali metal or alkaline earth metal salt of penicillin with a different metallic ion by subjecting a solution of the original penicillin salt to the action of a synthetic resin which is obtained by condensation of a polyhydric phenol and a methylene body.  The invention may be carried out either by using a resin which itself carries the metal ion it is desired to substitute for the original metal ion, in which case the desired product is obtained directly, or an acidic resin is used, in which case the primary product obtained is free penicillin which is then neutralized by a solution of the desired base.  The specification contains examples of both these procedures.  The preferred resin is that known as Amberlite IR-100 which is made by The Resinous Products and Chemical Co., and is described in the literature issued by them under the title "Amberlite Ion Exchange."  Specification 450,308 is referred to.

April 16, 1930, No. 12096. Convention date, April 20, 1929. [Class 38 (iii).] Safety arrangements.-A motor driving the arm of a distributer in multiplex telegraphy systems, and supplied with direct current impulses controlled by a vibrating drive relay, is arranged to be disconnected from the supply when the direct current impulses cease in order to prevent any damage of the trailing brushes on the distributer arm. The armature 116, Fig. 1, of the driving motor 114 is supplied with current from the secondary of a transformer 132, the primary of which is supplied with direct current impulses from the mains through a cut-out device 123, a series resistance 130, and a vibrating drive relay 125. Should the vibrating armature 127 of the drive relay 125 stick to one of its contacts 128 or 129, a continuous direct current is supplied to the primary of the transformer and since the impedance of this primary winding to continuous direct current is low, the current will be sufficiently high to cause the energization of the coil 134 of the cut-out device 123 which attracts armatures 122, 138, the former opening the motor circuit and the latter energizing a coil 136 to keep thearmatures attracted until released by a key 137.. Fig. 2 shows the invention as applied to a motor 24 of the La Cour type. In this case the impedance of the field winding 241 of the motor to continuous current is sufficiently low to cause the actuation of the cut-out device 223. In a modification of' the arrangement shown in Fig. 1, the motor circuit is kept closed by the attraction of the armature 122 by a coil energized across one or other of the windings of the transformer 132. In the application of this modification to a motor of the La Cour type the coil is energized by the potential across the field windings of the motor.
