Patent GB-976901-A (GB)
Title: Polyurethane elastomers
Inventor: WATSON JOHN WILLIAM
IPC: C08J9/00
Filed: 1960-07-07
Abstract: A polyurethane elastomeric material contains an ageing resistant agent comprising a dithiocarbamate compound of the general formula R1(R2)N-CSS-A-SSC-N(R3)R4 where R1, R2, R3 and R4 are alkyl or aryl groups respectively and A is an alkylene or arylene group. Amounts of dithiocarbamate from 0.01 to 5%, based on the weight of polyol from which the polyurethane is derived, are referred to. The resistance to discolouration is enhanced by using a peroxide as described in Specification 968,187 or by using a catalyst of the kind described in Specification 976,902.  In example (1) a prepolymer from polytetramethylene ether glycol (M.W.3000) and dicyclohexylmethane diisocyanate is mixed with anhydrous trimethylolpropane, dibutyl tin dilaurate and alkylene bis thiocarbamates of the above formula (or tetraalkyl thiuram disulphides in comparison examples), where A is methylene, ethylene or butylene, and the R's are methyl, ethyl, or butyl. The compositions are baked as films, and tested for strength and discolouration after ageing at 135 DEG C. In examples (4) and (5) foams are prepared from (4) a prepolymer from polypropylene ether glycol and toluene 2,4 and 2,6-diisocyanates, methylene -bisbutyl dithiocarbamate, water, silicone oil, N-methylmorpholine, triethylamine; (5) polyoxypropylene triol containing dissolved methylene -bisbutyl dithiocarbamate, water, water-soluble silicone, dibutyl tin dilaurate and toluene 2,4 and 2,6-diisocyanates.

Title: Improvements relating to the regulation of dynamo electric machinery
IPC: H02P9/26
Filed: 1944-11-28
Abstract: 595,141. Automatic control systems. ELECTRIC CONSTRUCTION CO., Ltd., and MILNE, J. C. Nov. 28, 1944, No. 23743. [Class 38 (iv)] Voltage; speed.-In an electronic field regulator for controlling the output of an electric generator or the speed of a D.C. motor, a potential which is a function of the generator output or motor speed is applied to the grid of a gas-discharge valve and operates to vary the ratio of conduction time to non-conduction time of the valve, thereby regulating the anode current which flows through the field of the generator or an exciter therefor, or the field of the D.C. motor. A flat, rising or partly compounded characteristic may be obtained with variations in the load of an alternator. In one example, Fig. 1, a potentiometer 4 is connected across the output circuit of an alternator 14, and a proportion of the voltage across the potentiometer is rectified through a half-wave rectifier 5 and applied across a condenser 6 and resistance 3 connected in parallel, a connection being taken to the control grid of a gas-discharge valve 1 and tending to hold that member biassed negatively. A resistance 2 connected between the resistance 3 and the cathode of the valve 1 has applied across it a constant D.C. potential in opposition to the potential across resistance 3. The anode of the valve 1 is connected through the secondary winding 7 of a transformer to the main field 10 of an exciter 11, which has a smaller winding 12 connected to a constant D.C. source and acting in opposition to the winding 10. The primary winding 8 of the transformer is connected across an A.C. main circuit, and a reservoir condenser 9 is connected across the secondary winding 7 and the cathode of the valve 1. A rise in generator voltage renders the grid of valve 1 more negative, thereby reducing the cyclic period of conduction of the valve and correspondingly reducing the exciter field 10 and the voltage of alternator 14 until stability is attained. In a modification, Fig. 3 (not shown), the regulator is arranged to give either a falling or rising output characteristic with increase in alternator load by applying to the grid of the discharge tube a control potential of a valve which is a fuction both of the alternator voltage and load current, this being obtained by rectifying the resultant of a tapped part of the output voltage and the secondary voltage of a current transformer which is connected either in phase or phase opposition therewith, the former giving a falling characteristic and the latter a rising characteristic with increased load.

[Also in Group XV] Cutting-apparatus for severing a connecting strip glued to the backs of books with a narrow gap between the books comprises a rotary knife 43 secured to an arm 51 on a shaft 47 adapted to be rotated periodically by a spring 49 so that the knife 43 is flicked over to sever the strip between books. The spring 49 is connected between a part secured to the knife 43 and a slipping clutch 48 which presses against a continuously rotating pulley 46 so that the spring is tensioned a predetermined amount after which the clutch 48 will slip. A stop 50 on the arm 51 is engaged by a lever 52 pivoted at 53 and the upper end being connected to the movable component 54 of an electric solenoid 55, momentary energization of which moves the detent 52 clear of stop 50 to permit one rotational movement only of the knife 43. Operation of the solenoid is effected by the passage of the books 17 through micro-switches A, B having operating levers 56 in the path of the books, the switch A being open and the switch B being closed when so projecting. Switch A will be closed by the first book so that one cut is made in front of the book before switch B is opened, thereby to break the circuit. Switch A is opened as the first book clears it and closed almost immediately by the second book, the circuit not being completed, however, till the first book clears switch B to energize the solenoid to cause the knife to sever the lining between the two books, this sequence then being repeated. Levers 56 are fitted with rollers of slightly less diameter than the normal gap between books so that if a roller will not enter the gap, no cut is made and the risk of cutting the book is obviated. Reference has been directed by the Comptroller to Specification 698,231.
