Title: Improvements in or relating to rubber products and methods of making the same
IPC: B29C41/14
Filed: 1938-01-07
Abstract: 509,015. Rubber sheets and threads ; metal foil. SPANEL, A. N. Jan. 7, 1938, No. 534. [Class 70] [Also in Group XXII] Rubber is deposited from latex on one or both sides of a sheet of metal foil, e.g. aluminium foil, to form a removable coating or coatings of rubber adapted to be subsequently stripped from the foil. Preferably, the compound sheet is cut to the shape of the desired rubber article, e.g. cut into threads, before the ,rubber is stripped, the foil after the stripping being scrapped. The rubber, while still on the foil, may be first partially cured by heating a hot gas or air, e.g. at 195-240‹ F. for 15 mins., and then treated with hot water, preferably boiling, to complete the cure. In the apparatus shown diagrammatically in Fig. 1, aluminium foil 6 from a roll R passes in succession through a latex bath T where both sides of the foil are coated, a drying oven 9, a curing oven 11, where the rubber is partially cured and a hot water tank 15 for completing the cure. The coated foil then passes between talcing rollers 21, 22 and is wound on a roll 25. When rubber threads are to be made, the coated foil, after passing the talcing rolls, passes under a slitting roll comprising a number of disc knives on a driven shaft. Preferably, the rubber is rendered somewhat rigid prior to the slitting operation, by being chilled, e.g. by solid carbon-dioxide. After the slitting the rubber is separated from the foil and wound on spools. To produce two rubber sheets of different thickness, the foil may be provided with a backing of porous paper. The rubber coating on the exposed surface of the foil is thinner than that on the paper side.

Title: Improvements in and relating to methods of and apparatus for loading flash lamps
IPC: F21K5/08
Filed: 1942-01-15
Abstract: 553,840. Pneumatic conveyers. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 15, 1942, No. 612. Convention date, Jan. 14, 1941. [Class 78 (i)] [Also in Group XXI] Extremely fine light-weight strips of combustible material are sucked into a flash-light bulb by exhausting the air or gas. The strips pass through a passage into the bulb and are impelled against the interior of the bulb with sufficient speed to bend or crumple them. In one form, Fig. 1, a strip 22 of aluminium is cut into strips by a rotating cutter 24 and the strips are sucked through a nozzle 21 into a tube 20 and thence to the bulb 10. Air is exhausted from the bulb by an exhaust system via an electrically-controlled valve 62, traps 59 and 61 which intercept stray particles of aluminium, and tubes 60, 45. One cutter 24 feeds two bulb-holding heads, 12, 12a, Fig. 2. The heads may be rotated to assist in uniform distribution of the strips. The cutter is rotated continuously, by means of a belt 33, pulley 31 and clutch 32, but the aluminium-strip-feeding rolls 26, 27 are rotated intermittently for definite periods at definite intervals so as to feed a definite number of strips to each bulb. This intermittent rotation is obtained by using spaced groups of gear teeth on a gear 35 forming part of the gear train by which the feed rolls 26, 27 are driven from the pulley 31. The suction heads 12, 12a are connected in turn to the exhaust system, so that one bulb is filling whilst the other (filled) bulb is being removed and examined ; this alternation of suction is obtained by means of a cam 71 (on the constantly-rotating shaft 72 which carries the gear 35) which operates a switch 66 which controls the valves 62, 62a which connect the suction heads to the exhaust system. After a bulb has been filled, the contents may be " fluffed " by means of a compressed air jet 73. Specifications 545,948, [Group XXI], and 550,085, [Group VIII], are referred to.

Title: Method for the recovery of free fatty and/or resinous acids from an aqueous solution of soap
IPC: C11B13/02
Filed: 1956-01-09
Abstract: Free fatty and resin acids are removed from an aqueous solution of soap such as soapstock, by adding an acid substance, such as hydrochloric or sulphuric acid or sodium bisulphate, with gentle stirring, to a prepared dilute solution of soap, to split the soap, and then subjecting the acidified solution to centrifugal separation so that the free acids and the acidified water are <PICT:0787715/III/1> discharged separately.  The degree of dilution of the soap solution is such that, when the amount of acidic substance required for splitting is added, there is instantly formed only an emulsion of the free acids of a low-viscosity oil-in-water type. In the preparation of the soap solution, acid water in an amount insufficient to split the soap is preferably used.  As shown, soapstock from tank 1 passes by line 4 to heater 5, where it is heated to 90-95 DEG  C. before passing to mixer 7, where it is mixed with water introduced through line 8.  From mixer 7 the soapstock passes to mixer 11, which is also supplied with concentrated acid through line 13 in an amount sufficient to split the soapstock.  The resulting oil-in-water emulsion passes through line 15 to centrifugal separator 16, where the free acids are run off through 17, acid water is discharged through line 18 and funnel 27 to tank 30, and any unseparated emulsion is passed by line 19 to tank 20.  This unseparated emulsion in tank 20, and the acid water in tank 30, are then introduced through line 8 to dilute the soapstock entering the process.  Excess acid water in tank 30 is run off to waste through 29.  Devices 9, 12 and 14 control the rate of flow of the various mixtures, the device 14 being actuated by pH meter 24 which has its glass electrode 23 immersed in tank 20.  The flow of concentrated acid to mixer 11 is thereby controlled so that the pH of the unseparated emulsion leaving the separator 16 is maintained constant. The soapstock, which may have an initial fatty acid content of about 25 per cent, is usually diluted before splitting to a fatty acid content below about 10 per cent.  Specification 719,472 is referred to.

Abstract: 799,979. Making bearing washers; sheet metal joints. VANDERVELL PRODUCTS, Ltd. Dec. 24, 1954 [Jan. 11, 1954], No. 731/54. Classes 83 (2) and 83 (4). A method of securing two metal parts together face to face comprises shearing a piece of metal partially out of one part to form on the face of the parts a parallel-sided projection having a length less than the thickness of the other part, forming an aperture in the other part corresponding in shape and position with said projection and having a depth greater than the length of said projection, bringing the two parts together face to face with the projection on the one part engaged on the aperture in the other part, and subjecting the other part to compression in a direction perpendicular to the mating faces of the parts to cause the walls of the aperture to move inwardly into tripping engagemeng with the sides of the projection. An annular bimetallic blank 1 composed of babbitt or lead bronze bearing metal 3 backed with a layer of steel 2 is placed on a die 4 having a pair of cylindrical holes 5. Co-operating with this die is a punch 6 having a pair of cylindrical projections 7 and 8 on its lower face. A spring- loaded stripper plate 9 passes over these projections. The projection 7 is of sufficient length to shear a hole 11 in the blank and the other projection 8 only penetrates through half the blank thickness to produce a cylindrical projection 12 on the lower steel face of the blank. The projection 12 is slightly larger in diameter than the hole 11 and a pair of blanks are assembled with the projection of each blank registering with the hole 11 in the other blank. The assembled blanks are then placed in a press and compressed to lock the blanks together to form the double-faced bearing washer as shown in Fig. 4. If the projection 12 passes through the other blank the protruding end is riveted over but if the face towards which the projection extends is a bearing surface the riveted portion must be below such bearing surface. Three or more parts may be joined together such as a light alloy or steel spacing sleeve 14 provided with annular bimetallic bearing surfaces 16 at each end as shown in Fig. 5.

Title: Integrated circuit with latch-up protection circuit fabricated by complementary MOS technology
Inventor: JOSEF WINNERL DR
IPC: H01L27/108
Filed: 1994-07-14
Abstract: A latch-up protection circuit for an integrated circuit using complementary MOS circuit technology has a substrate bias generator that applies a negative substrate bias to a semiconductor substrate having a p-conductive material into which a well-shaped semiconductor zone of n-conductive material is inserted. In order to avoid latch-up effects in the integrated circuit, an electronic protection circuit interrupts the capacitive charging currents of a capacitor in the substrate depending on the potential of the semiconductor substrate which is taken at a doped substrate bias terminal. The electronic protection circuit disconnects a capacitor bias generator from the capacitor when a voltage on the substrate bias terminal is greater than a difference between a reference potential and a threshold voltage of a first transistor in the electronic protection circuit. The electronic protection circuit connects the capacitive bias generator to the capacitor when a voltage on the substrate bias terminal is lower than the difference. No quiescent current flows through the electronic protection circuit during normal operation of the integrated circuit.
