Title: Saturant for fibrous bases and method of preparing same
IPC: D06M15/41
Filed: 1929-05-27
Abstract: 334,232. Novak, I. J. May 27, 1929. Phenol-aldehyde condensation products. - Liquid compositions for impregnating fibrous materials are made by condensing cresylic acid with formaldehyde in the presence of at least one molecular proportion of ammonia for every four of cresylic acid, thus forming an oil-soluble condensation product capable of transformation by heat to an infusible state, mixing this condensation product with china wood oil, and heating the mixture until it is sufficiently clarified to remain limpid when cool. Any excess of cresylic acid in the condensation product may be removed by an addition of hexamethylenetetramine or paraformaldehyde. When the solution of the condensation product in china wood oil has been clarified by heat, if desired with the addition of a small proportion of solvent naphtha, turpentine, or the like, it may be cooled rapidly to retard thickening. The concentrated impregnating solution may then be thinned with acetone, benzene, or other coal tar solvent before use. Modifying agents such as vegetable oils, pitches, and rubber, and also inert fillers may be added thereto or used therewith. The solution may be used for impregnating fibrous bases for clutch facings, brake linings, and the like, nlso cambric, paper, cotton braids for insulated wire, and other fibrous materials to which it is desired to impart body or hardness. Specifications 136,298, 255,516, 267,736 and 272,947 are referred to.

Title: Improvements in or relating to fluid pressure relief valves
Inventor: TEBB BERNARD
IPC: F16K17/08
Filed: 1958-05-22
Abstract: 925,590. Fluid-actuated valves. MASTABAR MINING EQUIPMENT CO. Ltd. May 15, 1959 [May 22, 1958; April 22, 1959], Nos. 16413/58 and 13690/59. Class 135. An excess pressure-relief valve in an hydraulic pit prop comprises a valve member carried on the forward end face of a piston and urged towards its seat by a spring and liquid trapped in a substantially closed chamber having one end wall formed by the opposite face of the piston and flowrestricting means downstream of the valve seat which on unseating of the valve member causes a build-up of pressure on the piston, rapid opening of the valve and a back pressure impulse acting on the rear face of the piston to assist the return of the valve member to its seat. As shown in Fig. 2 of the first Provisional Specification, a ball valve 18, carried by a stepped piston 22, 24 slidable with small clearances in bores 14, 15 and loaded by a spring 20, on being unseated allows restricted flow to an outlet 30. Pressure then builds up between the seat 16 and the forward face of the piston to cause rapid opening of the valve and a back-pressure impulse on the liquid already trapped in a substantially closed chamber 26 so that when the pressure at the valve inlet 12 falls the ball valve 18 is immediately reseated. As shown in Fig. 1 of the second Provisional Specification a loose ball valve 22 is carried by a piston 24 loaded by a spring 26. A chamber 12 behind the piston communicates through a bore 30 with an annular space between the housing 10 and the pit prop in which it is fitted. The space is limited by sealing rings 32, 34 to provide an auxiliary air chamber in which the air is compressed on the opening of the valve 22. The seat in this case is formed on a displaceable bush 16 sealed with respect to the housing and formed externally with a restricted passage leading to the outlet port 28. In a modification to the previous embodiment the outlet port and valve seat are adjacent each other and the restriction downstream of the seat is provided by the clearance between the valve housing and the pit prop. Specification 899,122 is referred to.

A cold connector for liquefied gases, e.g. oxygen comprises a double-walled heat insulated liquefied oxygen container 10, Fig. 1, having a liquid withdrawal duct 15 leading from a lower portion thereof and controlled by a pressure-closing valve 16, a combined pressure build-up and gas withdrawal circuit 21 comprising a warm-up coil 23 and a gas line 22 connecting said pressure closing valve 16 with the gas space of the container, and a valve controlled gas delivery duct 28 leading either from the pressure closing valve 16 as shown or from the circuit 21. During the filling of the container through a valved duct 26 a valve 24 in line 22 is vented to atmosphere. After closing the valve 24 liquid oxygen is fed by gravity through the open 16 and through the warm-up coil 23 and when the so vaporized oxygen builds up pressure in the gas space sufficient to close the valve 16. The latter allows access of gas to the delivery line 28 which includes a final warm-up coil 29. The gas withdrawal line 22 includes a relief valve 25. The container is insulated by powder in vacuum 13 between the inner and outer walls 11, 12. In a modification pressure build-up is effected by a flash evaporator pot 130, Fig. 2, located between the pressure closing valve 116 and the gas delivery line 128.

Abstract: 1,055,553. Tunnel diode circuits. LITTON INDUSTRIES Inc. April 24, 1964 [April 29, 1963], No. 17120/66. Heading H3T. [Also in Division G4] A data storage element comprises a tunnel diode arranged to be fed with reading and writing currents via an isolation diode, the isolation diode being maintained conductive during the reading operation irrespective of the voltage state of the associated tunnel diode. Writing.-The stage is initially cleared by reducing the voltage at C, Fig. 1, to zero so that transistor Q1 becomes cut off and tunnel diode TD1 is in its low voltage state. Transistor Q7 may be saturated by a short duration pulse at G so as to discharge the capacitance of line 4. If a binary 1 is to be stored, the appropriate word store is selected by saturating transistor Q2 by means of a positive pulse at A. The appropriate gate 22 is now opened by a positive pulse on the appropriate bit line I and a positive writing pulse at E, so as to allow a writing current I w  (greater than the tunnel diode peak current) to set the tunnel diode TD1 to its high voltage state. Reading-Q7 is first saturated by a short duration pulse at G so as to discharge the capacitance of line 4. The appropriate word store is selected by saturating Q2 by means of a positive pulse at A. The isolation diode D5 is turned on by a pulse at F which allows reading current I R  to flow in line 8. The voltage at 12 is thus high or low in dependence on the state of the tunnel diode TD1. Correction diode D9, identical to D5, compensates for the voltage developed across D5. Transistor Q5 is thus turned on only if a 1 has been stored, giving a negative-going output at J. Figs. 3-6 (not shown) relate to storage matrices (see Division G4).
