Title: Improvements in gelatine capsules
IPC: A61K9/48
Filed: 1943-12-14
Abstract: Capsules for accommodating measured quantities of insecticidal concentrates, insecticides, fungicides, antiseptics or powders, are made of gelatine tanned by external application of a tanning medium comprising benzoquinone.  The tanning is effected by pre-treatment of the capsule before the introduction of its contents, by immersion in a methyl alcohol solution of benzoquinone.  The portion of the capsule that is to form the seal may be left untanned until after sealing, and the sealed end may be made relatively thin so that it can be easily snipped off or pierced.  The flexibility of the capsule may be increased by incorporating a hygroscopic agent such as glycerine up to 20 per cent, in the gelatine of the capsule before tanning.  The Provisional Specification refers to the use of other tanning agents, such as formaldehyde, resorcinol, pyrocatechol, tannic acid and polymerised products of quinones, e.g. hydroquinone, and states that other protein capsules, e.g. capsules of casein, may be artificially hardened.  Also alternative methods of hardening consist in incorporating a tanning agent either in the concentrate, or in the gel material from which the capsule is made.ALSO:Capsules for accommodating measured quantities of insecticidal concentrates, insecticides, fungicides, antiseptics or powders, are made of gelatine tanned by external application of a tanning medium comprising benzoquinone.

Title: Improvements in and relating to emergency governor mechanism for prime movers
IPC: G05D13/08
Filed: 1921-08-10
Abstract: 187,069. British Thomson - Houston Co., Ltd., (General Electric Co.). Aug. 10, 1921. Stop-gear.-To enable an emergency governor to be tested without overspeeding the prime mover the governor, which is of the eccentricring type, is provided with means for increasing the centrifugal force whereby it will operate at a speed lower than that for which it is normally set. The governor comprises two rings 13, 14 mounted to slide transversely on a collar 19 on the shaft 11 driven by the prime mover. The centre of gravity of the ring is made slightly eccentric to the shaft by the addition to the periphery of a part 15, 16 which forms a pocket for retaining liquid supplied by a pipe 30, 29 when the governor is rotating. The weight and eccentricity of the centrifugal mass is thereby increased and the governor trips a lever to close the supply valve. The liquid gradually escapes through holes 32 provided in the pocket, after which the valve can be re-set. The spring 24 controlling the governor ring is separately adjustable by the screwed cap 26 for varying the speed at which the governor normally operates.

Counting-apparatus with variable-step movement.-The machine described in the parent Specification is provided with a signalling- device, such as a bell, indicating when the capacity of the revolutions-counter is exceeded, and with means for crippling such signalling device when the revolutions-counter is zeroized. A bell crank 20 pivoted at 19 has at one end a clapper 22 and at the other a nose 21 adapted to be depressed against the action of a spring 26 by a pin 23 on the last counting disc 2 when the capacity of the revolutions-counter is exceeded, the spring causing the clapper to rebound and strike the bell 24. On zeroizing, however, a deflecting pin 4 on the, shaft depresses a shifting lever 5 also pivoted at 19 so that an arm 25 on this lever 5 depresses the bell-crank 20 whereby the pin 23 cannot act on the nose 21 to ring the bell. The lever 5, on the first left hand rotation of the driving shaft 8 is returned to its initial position by a cam surface 17.

Title: Production of dimeric esters of crotonic acid
IPC: C07C69/56
Filed: 1947-08-05
Abstract: Dimeric alcoholic esters of crotonic acid are obtained by treating the monomer at 80-250 DEG  C. with up to 2 per cent of its weight of an alkali alcoholate and optionally in the presence of up to 15 per cent of its weight of a solvent.  The alcoholate functions as a polymerization catalyst.  The reaction is preferably completed at 200 DEG  to 250 DEG  C.  The products are esters of an unsaturated dibasic acid.  Esters used may be of mono or polyhydric alcohols. The alcoholate may be added to the reaction medium as such or prepared in situ from an alkali metal and an alcohol in which case excess alcohol is fractionated off during the course of the reaction. In examples: (1) methyl and (2) ethyl crotonate are treated with sodium and methyl alcohol at (1) 200 DEG  C. and (2) 220 DEG  C., for about 10 minutes, excess methyl alcohol being distilled off, to give on cooling, acidifying, washing and vacuum fractionation, the respective dimers, in (3) n-butyl and (4) b -ethyl-n-hexyl crotonate are similarly treated at the boiling point for about ten minutes and the respective dimers recovered as in (1) and (2).

Title: Method of and apparatus for oil purification
IPC: C10M175/00
Filed: 1945-08-22
Abstract: <PICT:0600332/III/1> Contaminated oil, whether of mineral, vegetable or animal origin, but particularly lubricating oil, is restored to a usable condition by heating and agitating it with an adsorptive material such as fuller's earth or activated bentonite to form a pool of slurry, withdrawing slurry from the pool and filtering it.  The pool is replenished with additional contaminated oil and adsorptive material substantially equal in amount to the slurry withdrawn, withdrawal and replenishing taking place continuously over a given period of time.  Control of the amount of slurry withdrawn is effected by utilizing the change in temperature of the pool resulting from the replenishing operation.  In Fig. 1, the pool of slurry is maintained in vessel 4 provided with electric resistance heaters 5 and propeller agitator 10. Contaminated oil enters the vessel through line 13, pump 14 and line 18, while adsorptive material enters through hopper 20, screw conveyer 22 and conduit 21a.  Pump 14 and screw 22 are driven by a common motor 23.  Pump 30, driven by motor 32, withdraws slurry from vessel 4 through line 27, multiple plate filter 28 and line 29, the outlet of the pump being provided with a discharge line 31 leading to oil storage.  The electrical circuit is arranged so that motor 23 stops when (a) oil pressure is insufficient to open valve 16, (b) float 33 rises above a pre-arranged level, (c) screw 22 has made the number of revolutions to deliver the amount of adsorptive material which will fill plate filter 28, or (d) foaming of the slurry causes submersion of thermostat 42.  Motor 32 stops when (1) the temperature of the pool falls below a pre-arranged value, (2) float 33 falls below a pre-arranged level, or (3) sufficient absorptive material has been delivered to vessel 4 to fill the plate filter.
