Patent GB-651305-A (GB)
Title: Improvements in the treatment of fibres, yarns and fabrics of regenerated cellulose
IPC: D06M15/423
Filed: 1948-05-13
Abstract: Fibres, yarns and fabrics of regenerated cellulose are treated first at a raised temperature with a solution containing a water-soluble salt formed from an organic base having one or more amino groups and an organic acid, and then with a solution of formaldehyde at normal temperature; the materials are then dried and finally heated to polymerize the base and formaldehyde.  The treated materials have reduced tendency to swell in water, increased strength in the wet state and reduced solubility in alkali leaches.  The first bath should contain a relatively large amount of the organic acid, which may be formic, acetic or lactic acid.  Zinc oxide or zinc thiocyanate may be added to this bath to assist in fixing the salt on the material.  In an example a woven viscose fabric is boiled for 1/2 hour in a bath containing per litre of solution 5 g. melamine, 1 g. zinc oxide (or 2.5 g. zinc thiocyanate) and 15 g. glacial acetic acid.  After removal from the bath it is squeezed to about 180 per cent of its original weight and then impregnated in a second bath containing a solution of 50 g. formaldehyde per litre of solution. It is then squeezed, dried on a stenter, and finally baked at about 150 DEG  C. for 6 to 8 minutes.

Inventor: MARSH JOHN OLIVER
IPC: F04D25/04
Filed: 1956-04-30
Abstract: 808,367. Centrifugal compressors; turbines. KIDDE CO. Ltd., W. April 25, 1957 [April 30, 1956], No. 13156/56. Classes 110 (1) and 110 (3). An inflation device comprises a stationary body adapted to be secured in the wall of an inflation bag, an impulse turbine wheel mounted for rotation in the body, a centrifugal impeller driven by the turbine wheel, a valve arranged between the impeller and the turbine wheel, and a jet nozzle adapted to direct gas from a highpressure supply on to the turbine wheel. The housing 8, Fig. 1, of the device is secured in the wall 9 of an inflation bag, such as an inflatable tent, by means of a ring 10. Gas from a highpressure supply, such as a gas bottle, is supplied through a pipe 6 to the nozzle 5, Fig. 3, of an impulse turbine. The turbine rotor 1 drives a centrifugal impeller 11. Instead of being direct, the drive may be through gearing. The impeller 11 draws in air through an inlet 14 and delivers it past a flexible valve 15 carried by the impeller and through diffuser blades 17. When the impeller has dropped to a speed at which it is incapable of forcing further air past the valve 15, the latter closes against an annular seating 16. The braking action caused by the initial partial engagement of the valve 15 with its seating increases the pressure differential tending to cause closure, resulting in a quick closure with minimum loss of gas. Specification 788,555 is referred to.

Title: Volumetric filling device
IPC: F17C5/02
Filed: 1968-03-20
Abstract: 1,205,846. Filling apparatus. APPLICATION DES GAZ. 20 March, 1968 [23 March, 1967], No. 13589/68. Heading B8T. A volumetric filling device, in particular for filling vessels with a liquefied gas, e.g. butane or propane, up to a given level, operates when a can 6 moves upwardly to engage the undersurface of a base composed of two plates 1, 2 having a bore 10 in which is disposed a valve 19 and valve rod 18, a flexible diaphragm 25 being connected between the base and the rod 18 to form a liquid chamber closed by the valve 19 urged on to a sealing ring 12 by a spring 16. Liquid is supplied to the chamber through a flexible line 14 and when a can engages the base 1-2 to lift the device, an inflatable sealing gasket 8 engages the inner surface of the can. The whole device is raised until the sleeve 22 on rod 18 engages a stationary stop 24 such that as the device is raised further the ring 12 is lifted off valve 19 thus allowing liquid to flow into the can to fill the can up to the level of the sealing gasket 8, and air and any excess liquid is allowed to flow out through discharge line 20, 21. The can is lowered, thereby allowing spring 16 to assert itself to stop the flow. An automatic rotary machine having such filling devices is described, Fig. 5 (not shown). In a modification, Fig. 6, liquid is supplied to the chamber 77 through a flexible line 78 connected with the valve rod 18. The base 70, 71 is integral with a casing 79 which surrounds a flexible spring 80 connected between the casing 79 and a cup-like member 81 integral with rod 18 and connected with the rod by a nut 83. The flexible line 78 is slidable in a sleeve 82 which acts as a stop for the bolt 83. A can lifts the device as a whole against the action of springs 75, the valve 19 being held on its seat by spring 80 and the differential effect of hydraulic pressure. When nut 83 is brought to a stop by sleeve 82 the rest of the device continues its upward movement until casing 79 comes up against plate 76 thus opening valve 19 and allowing liquid to flow into the can. When the can fills to the level of the valve, air and excess liquid flows through discharge tube 85, 86, 87 and thus into the inlet 88 of an adjacent filling device. Tube 85 is of small section such that the pressure builds up in the can and chamber 77 causing the valve to be closed by differential pressure.

Abstract: 1,026,563. Colour television receivers. PHILCO CORPORATION. April 5, 1963 [April 6, 1962], No. 13630/63. Heading H4F. An indexing signal at colour triplet frequency is derived from a beam indexing cathode-ray tube 22, Fig. 1, with the aid of a photo-cell 24 and converted in a chain of circuits 27-32 to two waves 25 and 26 having peaks which coincide respectively with the scanning of red and green phosphor strips, Fig. 2 (not shown). A received N.T.S.C. sub-carrier signal is demodulated in circuits 15 and 16 at phases # 1  and # 2  the first being in quadrature with the sub-carrier phase for green and at an angle less than 90 degrees with respect to the phase for red and the second being in quadrature with the sub-carrier phase for red and at an angle less than 90 degrees with respect to the phase for green, Fig. 3 (not shown). The resulting signal from circuit 15 modulates wave 25 in a balanced modulator 19, whilst the signal from circuit 16 modulates wave 24 in a balanced modulator 20. The outputs from modulators 19 and 20 are then combined with a luminance signal in an adder 33 and applied to modulate the cathode-ray tube. Modification of the form of the luminance signal may be achieved by combining with it portions of the outputs of circuits 15 and 16. Switches A-D are included for use in the initial adjustment of the circuit, particularly as regards the phase shifters 17 and 18 which determines the angles # 1  and # 2  of the local subcarrier demodulating signals which are applied to circuits 15 and 16.
