Title: Process for the preparation of foam plastics containing urethane groups
Inventor: DAHM MANFRED
IPC: C08G18/18
Filed: 1966-04-19
Abstract: Polyurethane foams are prepared by reacting a high molecular weight polyhydroxyl compound, an organic polyisocyanate, water or other blowing agents, in the presence of silicon-modified tertiary amine catalysts containing the group <FORM:1090589/C3/1> wherein R1 and R2 which may be the same or different represent alkyl, cycloalkyl, alkenyl and/or aralkyl radicals or together are members of a cyclo or heterocycloaliphatic radical or, with R1 having the above meaning, the radical R2 represents an oxyalkylene or aminoalkylene radical which is linked via the oxygen or nitrogen atom to the Si atom in the form of a silicic acid ester or amide, and the Si atom is part of a low M.W. polysiloxane, or of a silicic acid ester or amide.  Suitable catalysts are those having the formula <FORM:1090589/C3/2> wherein R3 is a C1- 4 alkyl radical, phenyl or vinyl and n is 0 to 4, mono-siloxy-N-heterocyclic compounds of the formula <FORM:1090589/C3/3> wherein m is 2, 3 or 4, compounds of the formula <FORM:1090589/C3/4> wherein the radical R3 is connected to the Si atom by an oxygen or nitrogen atom and 1,2,2,4-tetramethyl 2-sila-piperazine. The high M.W. polyhydroxyl compounds may be linear or branched polyethers, polyesters, polythioethers or polyacetals. Examples describe the use of a slightly branched polypropylene glycol prepared by reacting propylene oxide with trimethylol propane and a polyester derived from adipic acid, diethylene glycol and trimethylolpropane. The polyisocyanate may be aliphatic, araliphatic or aromatic, a mixture of toluene 2,4-and 2,6-diisocyanates being exemplified.  Conventional catalysts may be mixed with the silicon-modified tertiary amine catalysts of the invention, stannous octoate being exemplified. Foam stabilizers such as water-soluble organopolysiloxane -polyalkylene glycol ethers and emulsifiers such as sulphonated castor oils may also be incorporated in the reaction mixture.

Patent GB-590792-A (GB)
Title: Improvements in or relating to the preparation of complex lead salts
IPC: C07F7/00
Filed: 1944-09-11
Abstract: Complex lead salts are made by mixing lead monoxide, phthalic acid or anhydride, and a monobasic saturated aliphatic acid in the presence of water, preferably between temperatures of 15 DEG  and 100 DEG C. According to the proportions used, salts are formed corresponding to two formulae:-4 Pb C6 H4 (COO)2 . Pb (Cn H(2n-1) O2)2 PbO.2 Pb C6 H4(COO)2 . Pb (Cn H(2n-1 O2)2 Aliphatic acids specified are acetic, propionic, butyric, isobutyric, caproic, caprylic, stearic, and 2-ethylbutyric acid.  The resulting salts may be used as pigments either alone or in combination with each other or with lead phthalate.  When the aliphatic acid is soluble in water, it is preferable to carry out the reaction between 75 DEG  and 95 DEG C, but where it is more or less insoluble, it is better to charge the reactants into a ball or pebble mill at a temperature of 15 DEG  to 25 DEG C.  A number of examples are given.
Patent GB-1015335-A (GB)
Title: Valve
Inventor: BEARD JACK HERBERT
IPC: B30B15/18
Filed: 1963-05-02
Abstract: 1,015,335. Hydraulic presses. DAVY & UNITED ENGINEERING CO. Ltd. May 4, 1964 [May 2, 1963], No. 17355/63. Heading B5F. [Also in Division F2] Means for decompressing fluid pressure apparatus such as a press comprises an outlet controlled by a displaceable member urged in opposite directions by the fluid pressure, but with greater effect in the closing direction, and means for applying a further and increasing pressure in the opening direction. In the embodiment shown in Fig. 1, fluid under pressure is supplied by a line 40 to a main ram cylinder (not shown) and by a normally open valve 36 to the bore 30 of a cylinder 16 containing a piston part 28. The same pressure is also applied to a piston part 12, 22 but due to the area 33 being greater than the area 21 an orifice 20 is maintained closed. A spring 26 connects the piston parts 28 and 12, 22. In order to retract the main ram, supply of fluid to line 40 is stopped, a non-return valve 62 closes and the valve 36 is closed by a solenoid 37. Fluid under pressure is then supplied through a line 52 to the return ram cylinders (not shown), and through a line 58 to an annular chamber 60 in cylinder 16. This causes piston part 12, 22 to move to open orifice 20 thereby allowing fluid in the main ram cylinder to escape to a tank 48. As decompression proceeds a progressively greater pressure is required in chamber 60 to prevent the piston part 12, 22 moving downwardly and closing the orifice 20. The supply to line 52 is from constant output pumps so that decompression of the main ram system is smooth and constant. When pressure in the main ram system has fallen to a safe level, an exhaust valve 46 is opened by pressure in the return ram system and the return stroke of the main ram can be effected. Modifications.-In Fig. 2 (not shown) the valve 36 of Fig. 1 is replaced by a valve 78, 80, 82 housed in an extension of the cylinder 16. In the position shown, the valve part 82 holds a ball 84 away from a port 86 against the action of a spring 88. Passages 92, 96 and 98 are connected to the line 52 from the return rams, drain, and the line 40 from the main power ram respectively. In a further modification (not shown) the main cylinder pressure acts on the lower part of piston 22 (Fig. 1) and the return system pressure acts on an extension from the part 12. In a still further modification (not shown) the spring 26 in Fig. 1 is located in the cylinder above piston part 28 and this region may be open to atmosphere, the main cylinder pressure in line 34 being supplied to the chamber 68 between the piston parts.

Abstract: 184,152. Gas Research Co., (Assignees of Smith, H. F.). July 30, 1921, [Convention date]. Vapour engines.-In a continuously operating gas-producer system, a pump or the like for causing a blast of air with or without steam to pass through the producer, is driven by a hotair or like engine constructed to work upon a fraction of the heat generated in the producer, which can be operated at minimum capacity. The engine preferably works at high pressures and the working fluid may be a mixture of a fixed gas and a vapour. such as air and moisture, or hydrogen and carbon tetrachloride. In one form, Fig. 1, the engine 65 is embedded in the lining of the producer and the end 67 exposed to the heat of the producer is of a heat-resisting metal, e.g. an alloy of chromium and nicked. The engine comprises a piston 61 and a displacer 70 connected to crank-pins at right-angles to each other, the displacer rod 71 passing through packing in the piston 61. A water-jacket 66 on the cylinder is connected by pipes 81, 82 to a hotwater supply system. Instead of being embedded in the wall of the producer, the end 67 of the engine cylinder may be heated by the gases leaving the producer or by a burner supplied with gas from the producer. The Specification, as open to inspection under Sect. (91) (3) (a), comprises also a modification Fig. 6 (Cancelled) in which the displacer end 103 of the cylinder is heated by a burner 173 surrounded by a fire-brick chamber 171 and supplied with producer gas by a branch of the outlet pipe from the suction pump. A common piston 107 for the engine and the pump is provided with flexible bellows 110. The pump is formed by a cap or cylinder 155 provided with a disc inlet valve 158 and a similar outlet valve. The piston 107 and a refrigerator member 144 are connected by means of horizontal slots to two crank-pins 121, 119 on discs 120, 117 on a crank-shaft 116 rotating within a sleeve 126, which serves to space ballbearings 125 and is surrounded by a cage 127 and a sleeve 115. The cage and the sleeve are cut away to admit lubricant from a cup 129. Grooves to form a labyrinth packing are provided on the adjacent faces of the disc 117 and sleeve 115, and on a cap 131 and a member 132 held in place by a fly-wheel 133, which is enclosed in a fluidtight casing 180, 181. A starting-handle 183 slides in packing 188 in the casing member 181. The displacer comprises a hollow perforated cage 151, packed with regenerative material 152 such as glass wool and attached to the refrigerator member 144, Fig. 9 (Cancelled), which slides in heat-transferring relation to the water-jacketed cylinder wall It is cut away to receive the end of the crank-shaft &c. This subject-matter does not appear in the Specification as accepted.
