Title: New curable compositions
Inventor: CAMERON GRANT MCLAY
IPC: C08G75/14
Filed: 1965-02-22
Abstract: A composition comprises an ester or mixture of esters, containing on average more than 2 mercaptan groups per molecule, of one or more mercaptocarboxylic acids with one or more polyhydric alcohols having a molecular weight of at least 250 and containing on average more than 2 hydroxyl groups per molecule, and an oxidative curing agent for the said ester or mixture of esters.  The esters may generally be represented by the formula R(-O.CO.R1.SH)n and they may be mixed with a smaller amount of a diester of the formula R11(-O.CO.R1.SH)2, where R and R11 are hydrocarbyl groups which may contain oxygen in the chain, R1 is alkylene and n is an integer of at least 3.  The esters may be obtained by reacting the polyhydric alcohol with the mercaptocarboxylic acid in the presence of an acid catalyst and a water-immiscible solvent.  Specified mercaptocarboxylic acids (including mercaptopolycarboxylic acids) are 2 - mercapto - acetic and -propionic, 3-mercaptopropionic, 4-mercapto-butyric, mercaptoundecylic, mercapto-stearic, o- and p-mercapto benzoic and mercapto-succinic.  The polyhydric alcohol starting material is preferably that formed by the addition of an alkylene oxide to a triol, e.g. polypropylene triols having an average molecular weight of 300 to 25,000. Dihydric alcohols, e.g. hydroxyl terminated oligomers such as polyethylene and polypropylene glycols, mixed polyethylene polypropylene glycols, and poly(tetrahydrofurans) may be used to form the diesters.  The compositions may be cured with or without heating, specified oxidative curing agents being lead and tellurium dioxides, zinc and magnesium oxides, organic peroxides and hydroperoxides, and hot-curing agents such as p-benzoquinonedioxime. The compositions may also contain an accelator, an inhibitor, a retardant, a tackifier or adhesion promoter, or a filler or thixotropic agent.

Title: Binary counting circuit
IPC: H03K21/00
Filed: 1959-03-05
Abstract: 859,934. Electronic counting-apparatus. MONROE CALCULATING MACHINE CO. March 5, 1959 [March 12, 1958], No. 7661/59. Class 106 (1). A binary counting circuit comprises an nstage shift register in which the state of certain of the shift register stages controls the input to the register. As shown, Fig. 1, a shift register 2 is supplied with shift pulses from a pulse generator 30 over a line 4. The pulse generator 30 also supplies the input to the first shift register stage over a line 6 via a gate 18 controlled by a logical circuit 14 which receives inputs from certain of the shift register stages, e.g. over lines 8-13. The counter is started by a pulse applied over a line 26 to a gate 24 thereby allowing a pulse from the pulse generator 30 to set each of the shift register stages to a predetermined state, for example all "1's." The counter is stopped by a pulse applied over a line 36 to a gate 34 thereby allowing a pulse from the pulse generator 30 to set each of the shift register stages to a predetermined state, for example all "0's," such that the gate 18 is not enabled and the shift pulses effect no change in the state of the shift register stages. The logical circuit 14 may be as shown in Fig. 2A, inputs controlled by two of the shift register stages being applied over lines 8, 10 in permissive and inhibitory fashion to gates 42, 44, thereby causing an output on the line 16 when one stage only of the two stages to which the lines 8, 10 correspond is in the "1" state. In a modified logical circuit, two outputs are taken from the selected shift register stages corresponding to " 0 " and "1." For a shift register of n stages (n=2-7, 9-11), 2n - different states are obtained with the logical circuit of Fig. 2A. For n=8,12, however, the outputs from three shift register stages are needed to obtain 2n - 1 different states (Figs. 3A-4B, not shown).

Title: Polyisocyanate alkyd resin compositions
Inventor: SIMON ELI
IPC: C08G18/42
Filed: 1954-03-19
Abstract: Foams are produced by reacting a polyisocyanate, water and an alkyd resin derived from a dicarboxylic acid, a trihydric alcohol (with or without up to 40 mol. per cent of the total polyhydric alcohol of an alcohol having more than three hydroxy groups), and a dicarboxylic acid or hydroxy acid having from 15-20 carbon atoms or a dimer fat acid used in a proportion of 1-50 mol. per cent of total acid component.  The hydroxy to carboxy group ratio in the alkyd components should be between 1.5 to 1 and 3.5 to 1 and the acid number of the resin 0.5 to 100.  The quantity of water should be from 0.1 to 3.0 per cent by weight and the quantity of diisocyanate from 35 to 130 per cent by weight of the resin.  The water may be that present in the resin.  Long chain difunctional acids referred to are hydroxy palmitic, hydroxy stearic, ricinoleic and dilinoleic acid. Twenty-two examples are given of suitable alkyd resins using trimethylol propane, trimethylol ethane and pentaerythritol as alcohols, phthalic anhydride, adipic acid, maleic and succinic acids as dicarboxylic acids and dilinoleic, linoleic and hydroxy palmitic acids as the long chain difunctional acids.  The presence of the long chain acid in the resin is stated to result in a low-density foam of uniform small cell size and good physical strength.  The reactants may be allowed to react at room temperature and normal pressure but may be heated to about 135 DEG  F.  Post-curing may be effected for 24 hours at 120-300 DEG  F.
