Title: Improved manufacture of gelatine for photographic purposes
IPC: G03C1/047
Filed: 1934-01-06
Abstract: Gelatines from various sources, e.g. bones, calves' heads, skins or tendons, are treated, particularly for photographic purposes, to remove anti-ripening bodies, which are stated to be non-glutinous albuminous substances, with active carbon, silicic acid, or other adsorptive substances, or with dicalcium phosphate, followed by treatment with hydrogen peroxide for several hours, the hydrogen peroxide being rendered inactive with sulphur dioxide.  An inert basic gelatine capable of extreme ripening is obtained, to which any desired amount of the extracted anti-ripening bodies or artificial bodies having the same effect may be added, together with sensitizers, e.g. cystin or arsenobenzenes, if desired.  The anti-ripening bodies are recovered by treating the extracting agents with alkalis, and then neutralizing, e.g. with a suitable acid, e.g. nitric acid, which is employed in slight excess, followed by rapid concentration, preferably in vacuo.  According to an example, 100 kg. gelatine in a 5-10 per cent solution is treated at 60 DEG  C. with 15-40 kg. of active carbon.  After one hour, the carbon is filtered off and treated with N/10 caustic soda solution at 20-30 DEG  C.  The solution is then made slightly acid with ZN nitric acid and rapidly concentrated, and then added as desired to the basic gelatine.

Abstract: 789,148. Cycle foot rests. SOC. D'APPAREILS DE CONTROLE ET D'EQUIPEMENT DES MOTEURS, S.A.C.E.M. Jan. 6, 1956 [Jan. 25, 1955], No. 575/56. Classes 136(2) and 136(3) A pedal cycle which may have an auxiliary engine is provided with foot-rests 6 and retractable abutments means consisting of two longitudinal levers 8 which are capable, when in active position of limiting the free rotation of the pedal cranks 2 but which are normally held in an inactive position by a spring 14. Each of the cranks 2 carries a laterally projecting finger 7. The levers 8 are connected together by a cross member 9 journalled about a transverse pivot 10, each lever pivoting in a plane intersecting one of the fingers 7. A rod 11 guided in the support 6 is hinged to one of the levers 8. When the cyclist removes his feet from the pedals 5 and places them on the support 6 one of his feet pushes the rod 11 downwardly. This causes the levers 8 to pivot into the position shown in full lines in the drawing. If the cranks 2 occupy a position such that one of the pedals 5 is near the ground one of the levers 8 will come to bear against the corresponding finger 7 (then in position 7a) which causes the cranks to move in an anticlockwise direction and bring them into the position shown in the drawing where both pedals are far from the ground.

Filed: 1945-01-10
Abstract: 597,231. Fluid - pressure - operated brakes. MARTIN, J. Jan. 10, 1945, No. 830. [Class 103 (i)] [Also in Group XXIX] A servomotor for operating the wheel brakes of a motor vehicle comprises a spring-pressed servo-piston V and a co-axially arranged slidable control valve E actuated by the driver's wheel brake control, a valve L to bye-pass the oil supply to the servo-cylinder A and so cut by the driver's throttle control. As shown, the piston V has a hollow piston rod B connected out the action of the servomotor being operated by a lever D to the brake mechanism. Ports Q in the piston rod co-operate with ports S in a hollow valve rod E operated from the driver's wheel brake control through levers F, G. The cylinder has an oil inlet port P and an oil outlet port O, a passage W between these ports being controlled by a spring-closed valve L which can be opened to put the servomotor out of action by an arm J of a three-armed lever connected by a rod M to the driver's throttle control. An arm K of the three-armed lever has a pin Z movable in a slot I in a link H connected to the levers F, G. The slot I is arranged so that the movement of the valve L by the rod M is unhindered when the valve rod E is at or near its extreme outward position corresponding to the application position of the brakes. When, however, the brakes are off and the rod E is in the position shown in Figs. 1, 2, the link H engages the pin Z and the bye-pass valve cannot be opened by the rod M. Ports T for the exhaust of pressure oil are provided in the valve rod E and the piston V is loaded by a spring R. In a modification the slidable valve comprises a ported sleeve within the main cylinder, the servopiston sliding within this ported sleeve.
