Title: Improvements relating to the synthesis of chemical substances
IPC: B01J10/00
Filed: 1928-06-21
Abstract: 293,302. Polanyi, M., and Bogdandy, S. von. July 2, 1927, [Convention date]. Effecting chemical reactions by condensation on a surface.-Chemical reactions are effected by causing the reacting substances to pass in vapour or gas form and in a chemically active condition 'induced by superheating, electric discharges or by starting chemical reactions in their path, on to a common, preferably cool, surface whereon condensation takes place. The surface may be one moved at high velocity such as the exterior of a drum rotating at high speed, or it may be constituted by one of the substances which is to react in liquid form, which also may be moved at speed. An instance of the production of a chemically active condition by starting a reaction in the gas is the production of free atoms of hydrogen by the effect of sodium on hydrochloric acid. Apparatus as described in Specifications 269,586 and 266,316 may be employed in effecting the reactions.

Title: Improvements in lifting, lowering and hauling and especially in mine hoisting
IPC: B66B7/06
Filed: 1956-06-12
Abstract: 783,408. Winding installations. ANGLOAMERICAN CORPORATION OF SOUTH AFRICA, Ltd. June 12, 1956 [June 12, 1955], No. 18156/56. Class 78 (5). Lifting, lowering or hauling equipment comprises a driving wheel 23 around which the loadsubstaining rope 11 passes whilst being driven by the wheel, a winch drum 13 on to which the rope is wound, a motor 50 which drives the winch at a speed that ensures a rate of pay-in or pay-out exceeding the corresponding rate of pay-in or pay-out of the said driving wheel, loop-forming means 19 to form a loop in the rope between the wheel and the winch, and limiting means 39, 40 to maintain the length of the loop between predetermined limits while keeping the tension in the rope of the loop substantial constant. As shown, the rope from winch 13 passes round pulleys 15, 19, 21 and round wheel 23 and thence to the load. Since winch 13 pays-out the rope quicker than does the wheel 23, the loop around pulley 19 increases, thus permitting the pulley on its carriage 36 to fall till it strikes switch 40. The latter cuts-out motor 50 to stop the winch, the wheel continuing to pay-out the cable and carriage 36 rising till it strikes switch 39 to switch in the motor 50. In this way the carriage goes up and down whilst the cable is payed-in or out, the purpose being to lessen the tension of the cable wound on to winch drum 13 for very heavy loads. As safety measures, additional switches 41, 42 are provided and additionally, a brake is positioned at the top of the tower to jam the pulley 19 if it should rise too far. The system may have two or more ropes employing two or more sets of winch, carriage and wheel.

Title: Improvements in or relating to ejectors
IPC: F04F5/46
Filed: 1920-07-02
Abstract: 173,542. Wade, H., (Elliott Co.). July 2, 1920. Aspirating-apparatus, ejector.-Relates to apparatus employing steam, air or gas as the inducing-fluid for compressing elastic fluids and ejecting them, typically into the atmosphere, and consists in obtaining a high compression-ratio with single-stage working by the use of two nozzles or groups of nozzles, one group, taking a lesser quantity of the inducing-fluid, extending to no great distance into the converging part of the diffuser and being termed the accelerating nozzles; the other group taking a greater quantity of inducing-fluid, extending farther into the converging cone, and being termed the compressing nozzles. Several such forms are described. Fig. 1 shows an induced fluid inlet 3, inducing-fluid supply 9, accelerating-nozzles 8, and compressing nozzles 7 extending into the converging-cone 4 of the diffuser, which comprises also the throat 5 and delivery cone 6. The arrangement of the nozzles is illustrated in Fig. 2, which shows that compressing nozzles are of greater area. According to another arrangement the nozzles may be in three groups, projecting to different extents. Efficiency depends upon the relative dimensions of various parts, which are set forth in the Specification. Thus the angle of the diffuser should lie between 6‹ and 10‹, the nozzles should have an angle of 6‹, at least two-thirds of the steam or inducing-fluid supply should be taken by the compressing nozzles, the mixed steam and induced fluid delivered to the compressing nozzles should have a velocity lying between 750 and 2000 feet per second, and various relations should hold between the outlet and throat areas of the nozzles and the diffuser cross-sectional areas at the planes where they terminate.

Title: Improvements in electricity distribution systems and in load-shedding devices therefor
Inventor: KENDON SIDNEY PETER
IPC: H02J3/14
Filed: 1951-08-02
Abstract: 703,663. Load shedding arrangements. VENNER, Ltd. [Formerly VENNER TIME SWITCHES, Ltd.]. Oct. 31, 1952 [Aug. 2, 1951], No. 18344/51. Drawings to Specification. Class 38 (4) The voltage reduction in the supply system consequent upon overloading is utilized to cause the disconnection of the whole or part of any consumption circuit which at any time during the period of reduced voltage draws a current in excess of standard value allocated to that circuit. The voltage reduction may also effect a reduction in the magnitude of the standard value of current for the circuit as the magnitude of the voltage reduction is increased. In one arrangement, a relay for controlling the disconnection of the circuit has two opposed windings carrying, respectively, currents proportional to the system voltage and the circuit current, the iron armature of the relay, which operates contacts in the consumption circuit, being urged in a direction to open the contacts when difference in the field strengths produced by the two windings exceeds a predetermined amount. In another i arrangement a modified wattmetric type induction disc relay is employed, the relay having the usual voltage and current coils and, in addition, a further constantly but adjustably excited "current" coil which opposes the current coil proper and which may derive its excitation from a winding coupled to the voltage coil. Under normal voltage conditions and provided the current in the consumption circuit does not exceed a predetermined value, the torque produced on the induction disc by the three coils is sufficient to overcome the action of spring tending to return the disc to a position at which it closes a pair of contacts controlling a relay for disconnecting the consumption circuit from the supply. Upon reduction of supply voltage, the reduced torque on the induction disc causes a corresponding reduction in the maximum value of current which can be taken from the circuit before disconnection occurs. The relay controlled by the contacts of the induction disc is arranged to latch-out when operated and may be manually reset after steps have been taken to reduce the load on the circuit to a value below the maximum then permissible.

Title: Improvements in or relating to the control of five-electrode thermionic valves
IPC: H03C1/62
Filed: 1932-06-29
Abstract: 405,004. Valve amplifying and modulating circuits. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, and PADDLE, L. H., 35, Grove Park Gardens, Chiswick, both in London. June 29, 1932, No. 18345. [Class 40 (v).] A valve is rendered operative or inoperative according to whether a signal is applied to it or not by arranging that the signal varies the potential applied to an auxiliary grid, in addition to being applied to its control grid. The valve is preferably a pentode valve used as a low frequoncy amplifier (Figs. 1 and 2 not shown) or as a modulator, or high frequency amplifier (Fig. 6, not shown). Fig. 4 shows a valve 1 fed from high frequency oscillator 29 and modulated by low frequency amplifier 20. The bias of the auxiliary grid 1a is controlled by the signal through detector 5. If the anodebend detector is not completely nonconducting in the absence of a signal an additional negative bias may be applied as shown to the grid 1a or the valve may be rendered completely non- transmissive by the provision of the biassing resistance 31 and condenser. A low-pass filter may be connected to the input of amplifying valve 21 to prevent high frequency current fed through the interelectrode capacity of the valve 20 from reaching the detector 5. Fig. 5 shows a known carrier suppression system to which the invention is applied to prevent radiation due to lack of balance between the valve pair 1.
