Title: Process for the production of methyl trimethylol methane
IPC: C07C45/75
Filed: 1957-06-14
Abstract: Pentaglycerin (methyl trimethylol methane) is obtained from a crude pentaglycerin solution, obtained by the condensation of propionaldehyde and formaldehyde in the presence of calcium hydroxide, is neutralized or weakly acidified, the solution is partially evaporated and the calcium formate which separates is filtered off, the filtrate is further evaporated almost to dryness, the residue thus obtained is dissolved in an alcohol, the resulting solution is subjected at elevated temperature and at ordinary or elevated pressure to catalytic hydrogenation in the presence of an hydrogenation catalyst, and the hydrogenated solution is distilled in vacuo after the solvent is removed.  It is preferred to neutralize or slightly acidify the crude solution with formic acid.  The preferred hydrogenation catalyst is an activated nickel-cobalt catalyst, e.g. Raney nickel.  In the example a crude pentaglycerin solution is obtained by mixing formalin, calcium hydroxide and propionaldehyde; the pH is adjusted to 6.0-6.5 by the addition of formic acid; the solution is partially evaporated, calcium formate is filtered off and the filtrate is evaporated almost to dryness; the residue is dissolved in methanol, the solution is hydrogenated at 105 DEG  to 132 DEG  C. in the presence of Raney nickel and the product is distilled in vacuo to give pentaglycerin which may be further purified by recrystallizing from methanol.

Title: Non-woven conductive sheet material
Inventor: ATKINS HAROLD JEFFREY
IPC: H01B3/00
Filed: 1961-05-25
Abstract: 966,575. Fibrous fabrics. LANTOR Ltd. May 24, 1962 [May 25, 1961], No. 18927/61. Heading D1R. A method of manufacturing a non-woven flexible sheet material which is electrically conductive comprises bonding textile fibres together by means of a non-metallic bonding agent and incorporating particulate conductive matter in the sheet material. The bonding agent and the particulate material may be applied concurrently or the applications may be separate but successive. The bonding agent may be natural or synthetic rubber, a vinyl polymer or copolymer or a polyacrylic compound and the conductive matter may be conductive carbon or a fine metallic powder e.g. silver. The conductive matter may be applied by impregnating with a dispersion of the finely divided solid in water or an organic liquid and the dispersion may be applied by impregnation or it may be applied at the same time as the bonding agent. Preferably the dispersion is applied to a previously formed fibrous bonded fabric together with a thermosetting resin and/or rubber-like material to adhere the conductive material to the bonded fabric. Polyester fibres may be used for the bonded fabric to give good extensibility and elasticity and good resistance to attack by micro-organisms. As shown bonded fabric F is formed from a fleece P of polyester fibres by impregnating the fleece in a bath 10 of a resin mixture containing 93. 7% butadiene acrylonitrile synthetic rubber and 6. 3% melamine formaldehyde condensation product and heating the web in a device 12. The fabric F is then calendered between rolls 14 and then treated in a bath 16 with a mixture containing 75% of semi-colloidal graphite and 25% of polyacrylic resin. This then passes through squeeze rollers 18 and over drying cylinders 20.

Filed: 1943-11-16
Abstract: 573,252. Internal-combustion engines. AKT.-GES. BROWN, BOVERI, & CIE. Nov. 16, 1943, No. 19115, Convention date, Sept. 2. [Class 7 (ii)] [Also in Group XXVI] A turbine driven by exhaust gases from an internal-combustion engine, in which a quantity of fuel is burnt which is supplementary to that required for the production of useful power by the engine, the extra power being used in the turbine, is regulated by controlling the number of inlet nozzles used. The nozzle area may be varied in accordance with the power developed by the engine, by movement of valves covering the nozzles, or the partial covering and uncovering of a segment nozzles by a band. The nozzle area is decreased when the turbine power is to be increased. The regulation may be effected by the governing rodding of the engine, or by the engine-driven machine, and may be done electrically. The increase in back pressure on the engine exhaust by the closing of some of the nozzles, causes the engine governor to admit more fuel to the engine and thus increase its power. The turbine then supplies more power to the blower driven thereby, the blower supplying the engine

Patent GB-979124-A (GB)
Title: An injection or hypodermic syringe
IPC: A61M5/46
Filed: 1961-05-30
Abstract: 979,124. Hypodermic syringes. INTERNATIONALE TREUHAND A.G. May 30, 1961 [June 10, 1960; March 21, 1961], No.19503/61. Heading A5R. A hypodermic syringe comprises a medicament-containing cylinder 11a having a forward extension 11b, through which passes a needle 15, and a piston 13 with a central bore, in which a rod 14 carrying the needle is slidable under the control of a sleeve 10b, which is slidable on the cylinder, resilient means restraining the rod and a compression spring 18, which is locked until the rod has been released for projection of the needle and which is then released for projection of the piston to discharge medicament through the needle. A polyethylene medicament ampoule 11 is closed at one end by a bored rubber piston 13 and at the other end has an aperture sealed by a removable cap 12. A rod 14 slidable in the piston is operatively connected at the rear to a metal cartridge 10, which is slidable on the ampoule, and carries an hypodermic needle 15 which extends through the ampoule. An aperture 14a between the ampoule and the needle bore is covered by the piston bore when the syringe is inoperative. A compression spring 18 is held between the rear end of the cartridge and a locking disc 21, which is prevented from forward movement by spring arms 21a having bent portions 21b which engage the rear edge of the ampoule. A spring 20 connected with the disc 21 engages a peripheral recess 14b in the rod. In use, the cap is removed and the forward end of the ampoule is pressed against the skin. Hand pressure on the cartridge overcomes the spring 20 to allow the cartridge to slide over the ampoule and thus permit projection of the rod and the needle which then penetrates the skin, the aperture 14a thus being exposed to the medicament. Further pressure overcomes the locking effect of the spring arms 21a, so that the compression spring is released to cause projection of the piston and discharge of medicament through the needle. Movement of both the rod and the piston is limited by abutment against a tapering forward portion of the ampoule. After the injection, pressure on the cartridge is released and residual expansion of the spring withdraws the needle from the skin. The forward end of the rod may be spherical (Fig. 6, not shown) and engage a corresponding recess in the piston bore to lock the rod in inoperative position. In an alternative construction (Fig. 7, not shown), the locking disc is secured to the rod and is spaced from the piston so that, on expansion of the spring, the rod and needle are projected before the piston is engaged for discharge of medicament. The locking disc may have rearwardly extending spring arms (Figs. 9 and 10, not shown) which are held in engagement with the rear end of the rod by a sleeve fixed to a rearward extension of the ampoule. As the rod and locking disc are projected, the spring arms move out of the fixed sleeve and release the rod, so that further expansion of the spring causes only projection of the piston.
