Title: Combined shutter actuating and flash-bulb firing mechanism for photographic cameras
IPC: G03B15/04
Filed: 1946-12-03
Abstract: 620,067. Photographic cameras combined with flash-lamps. SINNOCK, H. J., and MICRO OPTICS, Ltd. Dec. 3, 1946, No. 35780. [Class 98 (i)] In a flashlamp and camera shutter synchronizer comprising means displaceable against the influence of spring means to free a normallylocked contact-carrying member, the spring means is capable of re-asserting itself to move the said contact-carrying member, when freed, to move the contact into engagement with an adjustable stationary contact to fire the flashlamp, and also to operate means for actuating the camera shutter. As shown, a rotor, consisting of two vertical coaxial discs 1, 2 spaced by a pin 3 adjacent their edges and an eccentrically-disposed pin 8, is supported at the centre of the discs by bearings 4, 5 carried by a contact setting member 7, rotatably mounted in the casing, and a wall 6. Two rods 9, 10 are pivoted on the pin 8 and surrounded by springs 11, 22. The disc 1 carries an arcuate face cam 24 forming the moving contact, and the stationary contact is formed as a projection 25 (Fig. 5, not shown) on a springy portion on a disc 26 mounted in insulation 28 carried on a sleeve 27, the construction tending to move the contact 25 inwardly towards the cam face 24. By rotating the setting member 7, secured to the sleeve 27 and having a scale co-operating with a mark on the casing, different shutter and flash lamp lags may be allowed for. The contact 25 is connected to the insulated member 32, which engages a battery housed at 31, into the top of which housing fits the flashlamp, by a strip 33 having a bent-down end 34 permanently engaging the disc 26 while the contact 24 and one side of the flash-lamp are connected to the casing of the device. On depressing a button 12, a shoulder 14 carried internally thereof engages the spring 11 and compresses it until a projection 21 on the button strikes the tip 20 of a bell-crank lever 18 which is adapted either by spring means or under gravity to bring a nose 16 into locking contact with a recess 19 in the disc 1. The discs thus released rotate under the influence of the compressed spring 11 to trip the shutter actuating mechanism by means of the rod 10, and close the contacts 24, 25 of the flash-lamp circuit, simultaneously compressing the spring 22. On releasing the button 12, the mechanism returns to the rest position shown under the action of this compressed spring. The length of the rods 9, 10 may be adjustable and the compression of the springs 11, 22 may also be adjustable to suit different kinds of camera.

Title: Improvements in or relating to converting rubber into compositions suitable for instance as varnishes, lacquers, and moulding material
IPC: C08C19/14
Filed: 1932-12-30
Abstract: A solution of unvulcanized rubber admixed with 5-20 per cent of uncombined sulphur is chlorinated to yield a thermoplastic mass suitable for the manufacture of films, varnishes, or mouldable compositions.  The chlorination is continued until the gel which forms is entirely redissolved.  The term rubber includes natural, artificial and reclaimed rubber, gutta, and balata with or without factice.  Metallic halides, oils, turpentine, chlorinated naphthalenes, tricresyl phosphate, organic esters, ethereal oils, cellulose plastic softeners, synthetic resins, varnishes, may be added before, during, or after chlorination.  According to an example, 10 gm. of masticated cr<\>zepe in 200 cc. of carbon tetrachloride is mixed with 1 gm. of sulphur and heated with chlorine until the gel which forms has redissolved into a mobile liquid.  The product is precipitated by the addition of 100 cc of alcohol which after washing in boiling water gives a white mass containing 32 per cent of chlorine, soluble in acetone and benzene to yield a transparent colourless film, mouldable at 130 DEG  C.
