Title: Improvements relating to apparatus for rectifying alternating currents
IPC: H02M7/06
Filed: 1926-12-23
Abstract: 264,809. Westinghouse Brake & Saxby Signal Co., Ltd., (Assignees of Ackerly, D. G.). Jan. 23, 1926, [Convention date]. Arrangements of asymmetric conducting devices.-In an arrangement for rectifying alternating current employing an asymmetric conducting-device such as that described in Specification 257,305, [Class 37, Electricity, Measuring &c.], in series with the load, a second rectifier is connected in shunt with the load circuit and in reverse sense, so as to reduce the reverse voltage applied to the load circuit and thereby increase the average useful current therethrough. The load L, Fig. 1, is alternately supplied during opposite half-cycles through rectifiers 7, 8, and the reverse voltages applied to the load circuits are reduced by rectifiers 5, 6 connected so as to load the transformer winding sections 2A, 2B when the voltages applied to the load through the rectifiers 7, 8 are in the wrong direction. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the arrangement shown in Fig. 1 (Cancelled), in which the load is divided into two parts L', L<2> connected through oppositely-disposed rectifiers 3, 4 to the terminals a, b of the supply transformer so that each rectifier circuit serves to cause a drop in the voltage applied to the other during that halfcycle in which current tends to flow in the wrong direction through the load. This subject-matter does not appear in the Specification as accepted.

Title: Process and Apparatus for the Continuous Coating of Individual Supports
IPC: B05C5/02
Filed: 1968-07-10
Abstract: 1,184,401. Coating apparatus. KALLE A.G. 10 July, 1968 [12 July, 1967], No. 32823/68. Heading B2L. In the coating of a succession of sheets 2 mounted on a support 1 and fed in close proximity to a coating die 4, the supply of coating material to die 4 is so regulated that as each sheet approaches the die the latter already has an accumulation 3 of material at its orifice and that thereafter the material is uniformly supplied to the die up to a point in the passage of the sheet when the supply is interrupted to ensure that the sheet is uniformly coated and that no material is applied to the support 1. Regulation of the supply is effected by providing two independently regulatable pumps, one pump being arranged to deliver material intermittently to provide the accumulation at the die on approach of a support, and the second pump being arranged to deliver material intermittently to provide the uniform supply during passage of the sheet.

Title: A process for the production of sulphur trioxide
Inventor: GUTH HANS
IPC: C01B17/765
Filed: 1961-09-14
Abstract: <PICT:0956049/C1/1> Sulphuric acid is produced from gases containing SO2, e.g. roasting gases or from combustion of sulphur, in a multi-stage contact process without supplying external heat, by heating a purified cool dry SO2-containing gas (9-12.2%) by heat exchange with reacted gases, passing sulphur dioxide and oxygen successively into a first and second contact stage, completely removing SO3 by absorption in sulphuric acid after the second stage, reheating the gases by heat exchange with the hot reaction gases from the second stage, passing the gases to a third contact stage which is not heated by the gases of the penultimate catalyst stage and absorbing the residual sulphur trioxide obtained. The intermediate absorption stage may be operated without completely removing the heat of absorption or modified by an oleum absorber preceding the sulphuric acid absorber which may avoid the need to cool the sulphuric acid. In Fig. 2, the major part of gases produced by roasting pyrites at 60-70 DEG  C. passes through heat-exchangers 1 and 2 to the first catalyst stage 3 at e.g. 590 DEG  C. where cold roasting gases are added via line 10 to avoid damage to the V catalyst by excessive temperature rise.  The gases from 3 are cooled, e.g. to 450 DEG  C., in exchanger 2, enter catalyst stage 4, are then cooled to 175 DEG  C. in exchangers 5a and 5b and enter intermediate absorbers e.g. trickling towers, 6a containing oleum and 6b containing sulphuric acid.  The oleum in absorber 6a is cooled at 9 and recirculated.  The gases from 6b, e.g. at 45 DEG  C. pass through drop separator 7, e.g. an asbestos filter, to remove entrained acid, are reheated by exchanger 5a, e.g. to 412 DEG  C., pass to final catalyst stage 8 and thence via exchanger 1 to a final absorber (not shown). A similar process is also described with a Figure, wherein exchangers 5a and 5b are replaced by a single exchanger and the absorbers 6a and 6b are replaced by a single absorber using sulphuric acid. Specification 904,982 is referred to.

Title: Hose fitting assembly
IPC: F16L33/01
Filed: 1977-08-08
Abstract: This disclosure deals with a fitting designed to be secured to an end of a flexible hose of the type including an inner tube surrounded by a wire reinforcement. The fitting includes a nipple, a sleeve and a socket. The nipple has a tubular part which is inserted into the end of the inner tube. The sleeve includes an insert part that is positioned between the end of the inner tube and the wire, and the socket is located around the tubular part of the nipple and around the sleeve. The socket is attached to the nipple, and the end of the wire reinforcement is clamped between the socket and the outer surface of the sleeve. The end of the inner tube is located in a pocket formed between the nipple and the insert part. During assembly of the fitting, the socket causes deformation of the insert part of the sleeve and initial compression on the end of the inner tube which is in the pocket. This initial compression combined with barbs formed on the insert, serve to secure the end of the tube in the pocket. Fluid pressure internally of the hose serves to activate a gland seal formed by the end of the tube in the pocket. Tapered surfaces of the socket and the insert part cooperate to deform the insert part in an advantageous manner.

Abstract: 1,047,710. Pulse modulation circuits. RANKBUSH MURPHY Ltd. Aug. 21, 1964 [Aug. 23, 1963], No. 33422/63. Heading H4L. A variable repetition frequency from the output 9 of an oscillator comprising a pair of similar transistors 1; 2 is produced by a modulating signal applied via terminal 12 to the base of a transistor 11 so that the current passing through resistor 14 and hence the current which is available to transistors 1, 2 is correspondingly varied. Assuming that transistor 1 has bottomed and transistor 2 is cut off, a constant voltage appears across the portion of the primary winding 3 of the output transformer which is in series with the collector of transistor 1 so that the current across this portion can only increase linearly with time. Since the total current available is controlled by the transistor 11, the base current is reduced as the collector current increases until the transistor 1 is no longer bottomed, the current through winding 3 ceases to change and the voltage across the winding falls to zero. A sudden change of voltage thus arises at the collector and the resulting voltage changes applied via winding 4 cause transistor 1 to be cut off and transistor 2 to conduct and the sequence is repeated.
