Title: Improvements in the manufacture of elastic products with a textile basis
IPC: D06M11/38
Filed: 1937-08-27
Abstract: Textile elements obtained by assembling two or more rovings, each individually twisted to a high degree and then twisting the assembly in the opposite sense to such a degree that each roving is largely opened up, as described in Specification 422,960 are made up into loosely woven fabrics, or web cords, subjected to a hydrolizing treatment in the presence of a wetting agent without tension whereby the fibres are swollen and contracted in length, e.g. with caustic soda, boiled in alkali under pressure, e.g. with sodium carbonate, washed and dried.  The material may then be impregnated with an elastic or plastic material such as rubber or balata, and vulcanized if desired.  The treatment excluding the final impregnation may be applied to the fibrous elements before they are woven.  The fabric may be vulcanized whilst stretched in any direction so as to limit the extensibility in that direction. The edges of the fabric are preferably cut off before vulcanization, to prevent buckling. Specification 434,049 also is referred to.

Title: Cathode ray polarograph
Inventor: DAVIS HERBERT MACDONALD
IPC: G01N27/48
Filed: 1959-07-10
Abstract: 891,988. Determining relative quantities of fluid-mixture constituents. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. July 5, 1960 [July 10, 1959], No. 23764/59. Class 37. In a polarograph apparatus in which a potential rising linearly with time is applied to the cell late in the life of each mercury drop, the cell current is modulated by the output of an oscillator so that it may be amplified in an A.C. amplifier, the amplifier output being rectified in a phase sensitive rectifier. A multivibrator 1 controls a generator 2 to produce quiescent periods and sweep periods during the latter of which a linearly rising potential is applied to the drop, the drop being caused to fall at the end of a sweep by a drop synchronizer 3. A sweep amplifier 4 maintains a constant rate of change of potential and a compensating circuit 8 compensates for the capacity effect of drop growth. The output current from cell 5 is made to flow alternatively in the two halves of the primary winding of a transformer T1, Fig. 2, by the output of an oscillator 18 acting on a bridge ring modulator D1-D4 to produce an alternating input to amplifier 9, and detection is effected by a phase-sensitive rectifier 10. A D.C. amplifier 11 is provided between the rectifier 10 and the Y plates of a cathode-ray tube 12, but the output voltage is so large that drift is insignificant. The X plates are energized by the sweep generator through an amplifier 13. In a modification described with reference to Figs. 3 and 4 (not shown), a second reference cell and a second modulator are included and the difference between the two modulator outputs is applied to the A.C. amplifier. In a further modified arrangement, the outputs of two cells are applied to a double modulator having a single output transformer.

Filed: 1936-09-01
Abstract: 469,523. Cutting clay. KOIDL, T. Sept. 1, 1936, No. 23900. Convention date, Sept. 2, 1935. [Class 87 (ii)] Building stones of any profile, particularly with tongued and grooved ends, are cut from a " string " of clay 17 by tensioned wires 13 which are guided while cutting transversely of the string by a stationary holder 6 and, while cutting in, at an angle to, or opposite to the direction of the string, by one or more movable holders 10 and the holder 6 jointly. A frame 1 is adapted to be reciprocated on ball races 3, being guided by rolls 4 on a frame 5 which carries the holders 6. The frame 1 carries the holders 10 and pivoted levers 9 which are connected to arms 11 carrying rolls 7 moving in slots in the holders 6 and rolls 12 moving in slots in the holders 10. The two cutting wires 13 are connected under tension to the rolls 12. The frame 5 is mounted on a table 25 which is moved to and fro on balltracks 19 according to the speed of the string. The string 17 advances over an oiling roller 30 until it contacts with a stop plate 21 when it carries the table 25 forward with it. The cutting frame 1 is then reciprocated by hand or automatically. The lever 20 is operated to withdraw the plate 21 from the path of the clay and to return the table 25 to its original position. In order to produce a cut of the form shown in Fig. 7, the holders 6, 10 have slots of the form shown in Fig. 4. As the roller 7 passes along the first portion of the slot in the holder 6, the two wires 13 produce the single cut 36. During the passage of the roller 7 from the first to the second bend in the holder 6, the roller 12 is forced to move up to the bend in the holder 10 and the wires 13 are rotated and moved to produce the double cut 37. The roll 12 is then at rest while the roll 7 moves to produce the upper horizontal cut and the first two motions are then repeated in the reverse order. A pawl 33 is provided which is engaged by a pin 35 on the holder 6 so as to move and block the roll 12 from returning down its original path.

Filed: 1935-11-09
Abstract: 470,326. Glass manufacture. EVANS, W. E. (O'Neill European Machine Co. of Montreal) Nov. 9, 1935, No. 23906. [Class 56] A machine for making glassware which gathers charges of molten glass by suction has each of the cut-off knives 44 carried by an oscillating shaft 45 which is adjustable axially and is also j ournalled in a tubular sleeve 80 on which the parts of the parison mould 111 are pivoted. The upper part of the shaft 45 turns within a collar 56 connected to a lever 59 which is rocked periodically by a stationary cam 63 and a coil spring 64. This spring normally keeps the knife 44 in an elevated position to one side of the mould 111, while the cam lowers the knife to the level of the bottom of the. mould before it makes a cutting-stroke. The knife is swung, to make a cutting-stroke, by an arm which is splined on the shaft 45 and is connected by a link with a lever 49 operated by a stationary cam 50. In order to adjust the position of the knife to suit parison moulds of different heights, the collar 56 is supported on a flanged sleeve 54<1> which is screwed on to the shaft 45. The collar 56 is held against rotation by a key 57 secured to the frame of the mould unit, so that rotation of the sleeve 541 raises or lowers the knife relatively to the collar. A lock-nut 55 secures the sleeve to the collar when adjustment has been made. The Provisional Specification describes also means for locking the parison moulds when they are closed, and means for opening the ring moulds, but these devices form the subjectmatter of Specification 470,325. Means are also described for establishing communication between a source of suction and a conduit in the neck-forming plunger, while the moulds are open, whereby air is drawn through the ring mould to cool the plunger.

Abstract: 944,822. Fluid-pressure brakes. BENDIX WESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. July 5, 1961 [July 14, 1960], No. 24282/61. Addition to 944,821. Heading F2F. The fluid-pressure braking system of the parent Specification is modified in that when the pressure of the source is below the predetermined value the cylinder for releasing the spring-operated actuator is exhausted from the second valve directly to atmosphere, so that the first valve does not have to be moved to its inoperative position to cause a spring brake application. As shown, the exhaust port 124 of the valve 92 is open to atmosphere, instead of being connected with the pipes 50, 52 leading to the compressed air actuators 36, 38 as is the case in the system disclosed in the parent Specification. An additional pipe 109 leads from the pipes 50, 52 to the exhaust port 108 of the quick-release valve 106 so that exhausting of the cylinders 74 is also effected via the driver's valve 34 when this is in the inoperative position. The valve 92 is simplified since it is no longer necessary to render it insensitive to change of pressure at the exhaust outlet, there being merely a valve member 132 comprising an inlet valve 134 and an exhaust valve 138, plunger 128 sealed by 0-ring 130, and spring 142.
