Title: Improvements in kinematograph projection apparatus
IPC: G03B19/18
Filed: 1947-10-08
Abstract: 652,616. Kinematograph projectors. DANEK, J. Oct. 8, 1947, No. 27034. [Class 97 (i)] The projector comprises a drive for the intermittent film feed mechanism, an operating member movable between positions in which it respectively permits and prevents the actuation of the film feed mechanism by its drive, a secondary drive for moving the operating member between such positions at a frequency less than that at which the film is advanced when the operation of the film feed mechanism by its drive is continuously permitted, and control means which can be set to permit such actuation of the operating member by the secondary drive, or to arrest the operating member, either in a position in which it permits, or in a position in which it prevents, actuation of the film feed mechanism, whereby the intervals between successive movements of the film from one frame to the next can be altered and prolonged indefinitely while maintaining constant the period during which each shown, intermittent movement of the film through the projection gate is effected by means operable by a disc 2 frictionally mounted on a rotating drive shaft 1 to rotate therewith in one direction only. To this disc is pivoted at 4 a lever 3 having a tongue 5 which is pressed into engagement with the surface of a cam 6 fast on the shaft 1 by a spring 7. When tongue 5 enters the recess shown in the cam surface, disc 2 rotates with shaft 1 and the film is fed through the gate. Control of the lever 3 is effected by another lever 11, which is pivoted at 12 and has at one end a stop 9 for engaging a projection 8 on lever 3 whereby said tongue 5 is moved out of the cam recess and the disc 2 is arrested and, at the other end, a roller 13 which rests on the surface of the operating member formed by a cam 14. This cam 14 is rotatable on a second drive shaft 15, which is rotated at a speed lower than that of shaft 1, and is secured to a disc 16 also rotatable on the shaft 15 by studs 17 which pass through arcuate slots 18 in the disc. This disc has a lever 20, which has a tongue movable into a recess in a cam carried by shaft 15 by spring pressure. The lever is movable out of the recess by means of pallets 21, 22 mounted on a pivoted escapement lever 23. Thus, when pallet 21 engages a stop 19 on lever 20 the disc 16 is arrested so that roller 13 engages the high point of cam 14 whereby tongue 5 on lever 3 continually engages the recess in cam 6 and disc 2 is rotated to move the film intermittently at a high frequency. When pallet 22 engages the stop 19, the cam is arrested with the roller 13 on a depressed part thereof so that lever 3 is disengaged from cam 6 and disc 2 remains stationary so that the film is not moved. When neither of the pallets engage the stop 19, cam 14 continuously rotates and so that disc 2 is moved only once per revolution of shaft 15 and the film is fed at a lower frequency.

Title: Compositions for the oxidative treatment of hair
Filed: 1960-08-05
Abstract: Compositions containing amino-1,3,5-triazine perhydrates are used for the oxidative treatment of hair, e.g. in bleaching hair, in dyeing hair with oxidation dyestuffs and in cold-waving hair. Triazine perhydrate compounds containing at least two amino groups, e.g. 2,4-diamino-6-phenyl-1,3,5-triazin perhydrate and melamine perhydrate, are preferably used.  The triazine perhydrates may be stabilised in solid compositions by the addition of magnesium silicate, monosodium phosphate, sodium pyrophosphate or phenacetine. The compositions may contain fatty alcohols, cholesterol, wool fat and plant extracts, e.g. camomile and coltsfoot.  Pulverulent mixtures which, when added to water or aqueous alcohol, may be used as a cream for dyeing hair, may contain an amino-1,3,5-triazine perhydrate, an oxidation dyestuff, e.g. the sulphates and hydrochlorides of p-toluylene diamine, m-toluylenediamine, aminophenol and amino diphenylamine, a thickener, e.g. tragacanth, polyacrylic esters, polyvinyl, pyrrolidone, carboxy methyl cellulose or alginates, and surface-active substances, e.g. alkyl sulphates and alkyl arylsulphonates.  In an example a process for cold waving hair is described in which the hair is first treated with an aqueous solution of thioglycollic acid adjusted to a pH of 9.6 with ammonia and then fixed with an aqueous solution or suspension containing melamine perhydrate.  Specification 883,268 is referred to.

Abstract: 748,934. Casting-machines. NEWTON, CHAMBERS & CO., Ltd. Jan. 29, 1954 [Oct. 29, 1952], No. 27214/52. Class 83 (1). A pipe 6 or other conduit is cast by pouring a charge of molten metal into a vertical mould 2 having near the bottom an internal flange 3 equal in width to the thickness of the conduit &c. and having a refractory plug closing the opening within the flange, the plug and mould then being moved vertically relatively to one another to produce an annular space continuously increasing in depth in which the metal flows and is solidified by cooling-water surrounding the mould in the vicinity of the plug. The plug comprises a nose 4 fixed to a hollow support 8 carried by a pipe 10 and cooled by water pumped by a pump 13 from a tank 30 through a pipe 12, within the pipe 10, and back through the space between the pipes 10, 12 to a tank 17. The lower end of the mould 2 has an external flange 14 acting as a piston in a cylinder 16 to which compressed air is admitted or released to raise or lower the mould. A second cylinder 20 surrounds the cylinder 16 and an annularpiston 22, connected by rods 24 to an external flange 25 at the top of the mould, slides in the space 23 between the two cylinders so that when the mould rises water is drawn into the space 23 from the tank 17 and as the mould falls water is forced on to the top of the piston 14, the mould, which has external cooling fins, being thereby surrounded by water to a level slightly below the nose 4. A sand socket-core 32 having a central metal-pouring passage 42, which also acts as an air vent, is held in position on the upper end of the mould by a clamping ring 34 on one arm of a spring-loaded bell-crank 36 whose other arm carries a roller 38 which, except when the mould is in its uppermost position, engages the inner wall of a stationary guidecasting 40 and thus locks the core in position. The mould is shown in its uppermost position with the cast pipe 6 about to be removed ready for a further charge of molten metal. By providing internal longitudinal fins on the mould a conduit may be cast which will easily break into two rain-water gutters or the like.

Filed: 1926-11-01
Abstract: 262,074. Bragg, C. S., and Kliesrath, V. W. Nov. 25, 1925, [Convention date]. Force - transmitting mechanism; fluid-pressure.-In crank arm transmitting mechanism for motor vehicles, the operated rod 55 and its crank arm 54 are arranged substantially perpendicular, while the operating rod 51 and its crank arm 52 are arranged at an angle to one another which is approximately 45 or less. With this construction, the slack of the brake is taken up quickly while the mechanical advantage increases as the brakes are applied. The device may be arranged between the pedal and the fluid pressure actuator shown in Fig. 4 and also between the actuator and the brakes. In the actuator, the inner sleeve 20 is connected at one end 22 to the foot or other operating connection, while an outer sleeve 5 disposed at the other end of the sleeve 20 and having a small amount of relative endwise movement is connected at 9 to the brake transmitting mechanism. The actuator piston 3 is fixed on one side to the sleeve 5 and on the other side to a similar sleeve 5a, both sleeves sliding in stuffing boxes in the ends of the actuator cylinder. The middle of the piston is provided with conical valve seatings co-operating with valves 40, 41, 42, 43 carried on the sleeve 20. The small amount of lost motion between the sleeve 20 and the piston with its sleeves 5, 5a serves to operate the valves in such a way that both ends of the cylinder are connected, when the brakes are out of action, to the interior of the sleeve 20 and thence to a pipe 62 leading to the suction side of the engine. This connection is made through the ports 34, 35, the valves 41, 42 and the port 24. When the sleeve 20 is moved in either direction, atmospheric air is admitted to one side so as to move the piston in the same direction. The atmospheric connections are made through the outer valves 40, 43.
