Title: Improvements in and relating to electric water heaters, boilers and the like
IPC: F24H9/20
Filed: 1930-08-30
Abstract: 360,542. Heating liquids by electricity. CRAVEN, F.- DE T., 44, West 75th, Street, New York, U.S.A. Aug. 30, 1930, No. 25999.

Title: Pulsed current sources for variable loads
IPC: G11C11/06
Filed: 1971-04-19
Abstract: 1341498 Magnetic storage arrangements; transistor switching circuits ELECTRONIC MEMORIES & MAGNETICS CORP 19 April 1971 [2 April 1970] 26040/71 Headings H3B and H3T In a driver circuit for a word or bit line of a magnetic core store, a current pulse of consistent amplitude irrespective of the number of cores to be switched in any read or write operations is provided by the combination of D.C. sources 13, 14, Fig. 1, transistor switches Q 1 , Q 2 , and a winding W 1  of an amplitude regulating inductor T 1  of rectangular hysteresis characteristic, initially biased well into saturation, the inductor being switched partially towards the opposite saturation state each time a driver pulse is applied to a word or bit line 10. Biasing- is effected by a D.C. source 11 which is coupled to an inductor winding W 2  through a choke coil 12. A current pulse is initiated by applying pulses to transformers T 2 , T 3  which switches on transistors Q 1 , Q 2 , thus applying both D.C. sources in sources to the line 10 to produce rapid current growth. After a time interval sufficient for the inductor core flux to commence switching, transistor Q 1  becomes non-conducting by cessation of the pulse in transformer T 2  and the core switching current is maintained by power source 14 over diode D1. Subsequently the pulse at transformer T 3  terminates before the inductor core switching is complete and transistor switch Q 2  opens and disconnects the power source 14. During the operation choke coil 12 acquires energy, and when transistor Q 2  becomes non-conductive this energy is transferred to the power source 13 over windings W 1 , W 2  and a circuit comprising diodes D 1  and D 2 . A plurality of driver circuits for two adjacent word or bit lines L 1 , L 2  is shown in Fig. 3, respective currents I for a particular read or write operation passing through the lines in opposite directions. Each line, such as L1, has its individual read and write driver circuits comprising transistors Q 1 , Q 2 , Q 3  and inductor T 1  for reading, and transistors Q 4 , Q 5 , Q 6  inductor T 4  for writing, all the inductors having a common bias circuit. Each pair of adjacent lines with oppositely directed currents for a particular read or write operation forms a closed loop system.

Title: Improvements in felt conditioners
IPC: D21F1/32
Filed: 1944-12-28
Abstract: <PICT:0595612/IV/1> <PICT:0595612/IV/2> Paper machine felts are conditioned while moving at high speed by subjecting limited areas of the felt to a series of rapidly repeated conditioning cycles, each involving the injection of cleaning fluid into the felt, followed immediately by vacuum extraction of at least a portion of the fluid injected, the treatment being simultaneously accompanied by a scraping of the felt surface.  The limited areas are treated in succession in a direction widthwise of the felt and the rate of progressive extension of the treatment across the felt is such as to ensure treatment of the entire length of each widthwise element of the felt.  The conditioner may be mounted and traversed across the felt in the manner described in Specification 188,023, [Class 46], and consists of a casting 22 divided into a vacuum chamber 24 and a water chamber 26 connected by conduits 44 with slots 48 in the cover 32.  The vacuum chamber is in communication with slots 51, 52 and 54 in the cover 32 and is provided with vacuum and drainage connections 36 and 38.  The length of the water slots 48 across the width of the conditioner is less than that of the vacuum slots.  The felt 12 passes over the conditioner in the direction indicated by the arrow in Fig. 8 and a scraping action is exerted on the felt by the trailing edges of the suction slots.

Sept. 19, 1932, No. 26058. Drawings to Specification. [Classes 39 (i) and 40 (v).] In thermionic amplifiers, the control electrode to which the input signals are applied is coated with a laver of barium or other electronemitting material and is biassed positively so that the rate of change in the number of electrons reaching it pursuant to changes in its potential is substantially equal to the rate of change in the number of secondary electrons drawn from it to the anode. The output impedance is low and the dynamic input impedance high. The control electrode may be a grid of a large number of fine nickel wires and is coated with a thin layer of barium. evaporated from the filament or with a layer of thorium. The filamentary cathode is short and heavy and the cathode-grid and grid-anode spacing is larger than usual. A space-charge results about the filament and secondary electrons from the grid wires are easily drawn to the anode. Amplifiers are described in which the valve is of the triode or screen-grid type, the screen serving in the latter case as the positive control electrode and the inner grid being at positive, zero or negative potential with respect to the cathode. Specifications 187,233 and 302,307, [both in Class 39 (i)], are referred to.

Abstract: 992,013. Treating polyester filamentary materials and films. FARBWERKE HOECHST A.G. July 19, 1961 [July 19, 1960], No. 26163/61. Addition to 903,913. Heading B5B. The properties of films or filamentary materials of linear, high molecular, six-membered carbocycle containing polyesters, having a specific viscosity of 0.45 to 0.65, determined in 1% solution in a mixture of 60 parts by weight of phenol and 40 parts by weight tetrachloroethane at 25‹ C., are improved by treating said materials for a period of 10<SP>-4</SP> to 10 sees. at 200-350‹ C. with nitrogen-free organic compounds containing from 1 to 6 reactive terminal radicals selected from the group consisting of the carboxyl, hydroxyl, -PO 3 H or -SO 3 H radical, which compounds are liquid or gaseous at the treating temperature and capable of reacting chemically with the film or filamentary material at said temperature. Treatment may be carried out at 210-280‹ C. and for from 10-<SP>1</SP> to 5 sees., and, where filaments are treated, the tension of the filaments may be so adjusted that they are allowed to shrink by 5 to 35% referred to the original length. The filaments may be stretched after treatment, e.g. to a draw ratio of 4.3. Materials may be treated in a liquid bath having a temperature of 200-350‹ C., or may be contacted with the said compounds and then heated in known manner for 10<SP>-4</SP> to 10 sees. at 200-350‹ C. Preferred treating agents include carboxylic acids having 6-18 carbon atoms and 1-4 carboxylic groups, monohydric alcohols having 6-26 carbon atoms and polyhydric alcohols having 2-10 carbon atoms and 2-6 hydroxyl groups. A long list of suitable compounds is given. After treatment, excess treating agent is removed from the material, e.g. by heating. Treatment improves the dyeability of the materials and reduces the breaking strength, so reducing the tendency to pilling.

Filed: 1957-08-23
Abstract: 831,239. High-tension switches. CANADIAN WESTINGHOUSE CO. Ltd. Aug. 23, 1957, No. 26711/57. Class 38 (5). In a gas blast circuitbreaker in which the gas also produces the opening movement of the movable contact, the arrangement is such that the contacts do not open until adequate pressure for arc - extinction is available and then remain open notwithstanding variations in pressure due to the arc. The parts shown are enclosed in a pressure-gas-chamber and comprise the hollow movable contact 2 blocked in the closed position by the fixed contact 1. When the passage 3 is vented to the atmosphere the contact 2 is moved if the gas pressure on the annular top 6 of the contact 2 is sufficient to overcome the spring 12. After a short contact movement an annular piston 8 on the contact 2 closes vents 15 so that the space between the contact 2 and a cylinder 9 is cut-off from the gas supply. Also vents 16, 17 come into line so that the space is open to the atmosphere and the gas pressure also acts on the piston 8 to increase the speed of contact travel. In the fully-open position the vents 16, 17 move out of register so that the pressure cylinder 9 is unaffected by pressure changes in the passage 3 due to the arc. Contacts 14 ensure a low resistance path from the cylinder 9 to the contact 6. Specification 736,090 is referred to.
