Abstract: 1471353 Flexible bags L BRENDLING 24 July 1974 [25 July 1973] 32732/74 Heading B8K [Also in Divisions A3 and A5-A6] A flexible bag, e.g. of plastics or rubber is flat when empty and comprises two outer walls with intermediate walls arranged between them to form an uneven number of at least three chambers in connection with each other, an inlet (1) with a valve (3) and optionally an outlet (5), characterized in that: the same number of intermediate walls are arranged on each side of a line through the middle chamber in the longitudinal direction of the bag, the intermediate walls are connected to the outer walls along joints extending normal to the direction in which the chambers are linearly disposed and the distance between the joints of at least one pair of adjacent intermediate walls at one outer wall is longer than the distance between the joints of the same adjacent intermediate walls at the other outer wall. Fig. 2a shows a section through an empty bag comprising outer walls 7, 10 of the same size and shape as intermediate layers 8, 9. Selected combinations of the outer walls and intermediate layers are welded at seams 11, 11<SP>1</SP>, 12, 12<SP>1</SP>, 13, 13<SP>1</SP>, 15, 15<SP>1</SP>, 17 and 17<SP>1</SP>. When fluid is added between layers 7, 8 they separate from each other between seams 13, 13<SP>1</SP> and the fluid flows through holes 14 and 14<SP>1</SP> in layer 8 to separate the latter from layer 9 between seams 12 and 15 and between seams 12<SP>1</SP> and 15<SP>1</SP>. Fluid then flows through holes 16, 16<SP>1</SP> in layer 9 to separate layers 9 and 10 between seams 11 and 17 and between seams 11<SP>1</SP> and 17<SP>1</SP>. The fluid pressure forces each chamber to adopt a rounded shape with a straight intermediate wall, the whole bag arching as shown in Fig. 2b. To reduce the bag thickness, parts of the intermediate layers not forming intermediate walls can be omitted. If the number of chambers is greater than 3, then out of two adjacent intermediate walls, that wall further from the middle chamber is the broader one. In Figs. 1a 1b (not shown) the intermediate layer is a broad band.

Abstract: 847,983. Voice-frequency receivers. TELEFUNKEN G.m.b.H. Dot. 14, 1958 [Dot. 16, 1957], No. 32745/58. Class 40 (4). Mark and space pulses of frequencies f 1  and f 2  are received by associated transistors Tr 1  and Tr 2  to control a differential relay which is normally energized by current over a transistor Tr 3 , detection of f 1  by Tr 1  cutting off Tr 2  and Tr 3  and detection of f 2  by Tr 2  cutting off Tr 1  and Tr 3 . The receiver is described as applied to a system of communicating over high voltage power lines the frequencies f 1  and f 2  being transmitted by carrier and being outside the range used for transmitting speech. After demodulation and filtering, the frequencies are applied to Tr 1  or Tr 2  which work in class C and energize winding w 1  or w 2  of relay W. Current in R 3  when one of Tr 1  or Tr 2  conducts cuts off the other and current through either produces a potential across R 7  which cuts off Tr 3  normally energizing W over w 3  in the absence of f 1  or f 2 . The frequencies f 1  and f 2  are passed onwards over transformer U and are utilized as a pilot for volume control. With a speech range of 300 to 2,200 cycles the frequencies f 1  and # 2  are given as 2350 and 2450 cycles. Capacitors C 1  and C 2  give the cut-off voltages a time constant to cover possible gaps between the mark space pulses of f 1  and # 2 .

Title: Silicon carbide semiconductor devices
Filed: 1961-09-13
Abstract: 929,421. Semi-conductor devices. WESTINGHOUSE ELECTRIC CORPORATION. Sept. 13, 1961 [Sept. 29, 1960], No. 32801/61. Class 37. A method of fixing a high temperature contact member to a silicon carbide wafer comprises depositing a thin layer of silicon or silicon alloy on the surfaces of the contact member and wafer to be joined, placing the contact member and wafer together with the coated surfaces mating, and heating the resulting sandwich so that the silicon or silicon alloy fuses and bonds the contact member to the silicon carbide wafer. The high temperature contact member may be of tungsten, platinum, palladium, molybdenum, iron, silver, or nickel, or alloys such as silver-tungsten or nickel-tungsten which have a melting point above 1000 F. The silicon or silicon alloy coating may be deposited in vacuum or in an atmosphere of gas that is reducing or inert to the materials involved, and may be deposited by evaporation techniques, sputtering, or by using a molten jet. The thickness of the layer of silicon or silicon alloy deposited determines the temperature at which final alloy fusion takes place and is preferably kept to the minimum necessary to cover the mating surfaces of the wafer and contact member. A suitable silicon alloy for coating is said to be 50: 50 silicon-silver. When the sandwich is heated it is held under pressure by a spring or in a jig. The resulting structure using silicon as a coat comprises layers of tungsten, tungsten-silicon alloy, an alloy of tungsten silicon carbide and silicon, a silicon silicon carbide alloy, and the silicon carbide crystal. In a specific method of coating a single crystal silicon carbide wafer, the wafer is placed with a mass of silicon (or silicon-silver) in an open carbon boat in vacuum, separate means being provided to heat the wafer to something less than 1400 C. with the boat while the silicon mass is raised above 1450 C. to cause its evaporation. The tungsten contact member is coated by a similar procedure. The sandwich is fused under pressure at a temperature between 1500 C. and 1800 C. It is stated that the contact member or the silicon, or both, may be doped with antimony or aluminium to produce a fused junction in the wafer crystal of silicon carbide which may itself be intrinsic or be doped.
