Title: Photographic apparatus
IPC: G03B17/24
Filed: 1969-04-08
Abstract: 1,243,458. Photographic cameras. IDENTIFICATION DEVELOPMENT CORP. April 8, 1969 [April 8, 1968], No. 17913/69. Heading G2A. A photographic camera 12, Fig. 1, has four optical channels 18 associated with four apertures 14, a lens turret 24 being rotatably mounted about a shaft 28 on the front of the camera and carrying a lens 30, rotation of the turret indexing the lens into four successive positions each aligned with one of the apertures 14 so that the regions 18 can be sequentially exposed through the lens. A shutter plate 32 having four exposure apertures 34, Fig. 3, is rotatably mounted on the turret shaft 28 and biased in a clockwise direction by a spring 36 so that a stop segment 38 abuts a fixed stop 40. To make an exposure, a timing disc 46 is rotated one complete revolution during which a pin 44 carried thereon engages a slot 42 provided in the shutter plate to move the plate to expose all four apertures 14. When the apertures are fully uncovered a switch 52 is closed to energize a flash device. Continued rotation of timing disc 46 carries pin 44 out of engagement with slot 42 and the shutter plate is driven back to its initial position under to action of spring 36. Futher rotation of timing disc 46 causes turret motor 74 to be energized which rotates lens turret 24 via a friction drive wheel 72. Lens turret 24 is provided with four angularly spaced detents 86 engaging sequentially a contact arm 84 of turret stop switch 80, the turret thus rotating until the lens is aligned with the next region 18 to be exposed.

Title: Improvements in or relating to sand moulds for steel castings
IPC: B22C9/00
Filed: 1942-12-18
Abstract: 570,953. Moulds. SULZER FRERES SOC. ANON. Dec. 18, 1942, No. 17983. Convention date, Dec. 20, 1941. [Class 83 (i)] A sand mould for casting steel billets is formed internally with convex surfaces 8 so that the solidifying billet has, at first, a crust in the form of arches 18 which does not crack by reason of the pressure of the internal liquid 5 and the contraction, due to sintering, of the sand 2. The sand opposite the points 7 of the casting is not heated thereby to above its sintering temperature and therefore does not yield to radial pressure at these points. The surfaces 8 may run circumferentially, spirally, or radially instead of longitudinally, as shown.

[Also in Division C7] A workpiece of e.g. steel 7 is surface hardened by a plasma 6 generated by a plasma jet apparatus comprising a single hollow or solid electrode 2 supplied by a high frequency (10-100 Mc/s) generator 1, and a surrounding tube 3 supplied with an ionizable gas stream, the electrode 2 producing a high frequency radiation field with a high electric field strength which only heats the plasma strongly at the transition point between the plasma and workpiece. It is stated that neither the plasma nor the centre of the workpiece are strongly heated by the radiation field and that accordingly the cold plasma can be shaped with a non-conducting nozzle 8. The tube 3 can be omitted and the ionizable gas supplied through a hollow radiating (copper) electrode (Fig. 2, not shown). The workpiece 7 acts as an energy radiator and the amount of power absorbed at its surface can be adjusted by connecting an adjustable aerial to the workpiece.

Abstract: 1505889 Storage and test container BATTELLE MEMORIAL INSTITUTE 1 May 1975 [10 May 1974] 18295/75 Heading G1B [Also in Division B1] A device in which liquid to be analyzed can be stored prior to analysis comprises a body having at least one U-shaped compartment having first and second inter-connected limbs 2, 3 with a reaction zone in the vicinity of the inter-connection between the limbs, a liquid inlet passage 22 at the free end of limb 2, limb 3 being closed by a selfsealing material 33 at a point spaced from the reaction zone, opposed wall portions of the body adjacent the reaction zone being of light-permeable material. The device shown is made from two inter-fitting portions 7, 8 and comprises a plurality of U-shaped compartments formed by extension of a series of tongues 11 dependent from upper portion 8 into compartments in the lower portion 7, the upper ends of the compartments being open into a common space communicating with opening 32a (Fig. 2) covered by parts 34 of portion 7 of the device such that insertion of a syringe needle through a part 34 into the common space and application of suction allows liquid to be drawn into each of the passages 22 for storage in the device. For use, the device is disposed on a frame 40 having a spring-loaded arm 41 pivotable at 40a, arm 41 being driven downwardly on rotation of cam 45 which bears on sensing means 44 to force lancet 42 through self-sealing diaphragm 33. To allow the liquid from passages 22 to flow into contact with reagent already in the reaction zones 4, cam 45 provides for insertion of only the tip of lancet 42 into the device, air leak 42a remaining outside the device. For mixing of the reagent and liquid, the lancet is driven further into the device and co-operation of corrugated section 45c of cam 45 with sensing means 44 causes reciprocating movement of the end of arm 41 which bears against diaphragm 33 Fig. 1c (not shown) and consequently of the liquid within the device.

Abstract: 749,963. Counting-apparatus. VEEDERROOT, Inc. June 28, 1954 [July 13, 1953], No. 18887/54. Class 106 (1). A counter comprises a shaft journalled in a casing, a plurality of digit wheels rotatably supported on the shaft in adjacent relation, annular interlocking means on said wheels for mutually engaging the wheels in rotative nesting relation, additional annular interlocking means on the casing which engage the end digit wheels in nesting relation, the arrangement being such that the digit wheels are mutually self-supporting in the casing when the shaft is removed. Each digit wheel 10, 12, 14, 16 has at one side a boss 34 and at the other a ratchet wheel 24 having a recess 32. The boss 34 of one wheel engages the recess 32 of the next highest wheel. An adjustable screw bearing 6 carried by the casing 2 enters the recess 32 of the first wheel and a bearing 8 also carried by the casing 2 receives the boss 34 of the last wheel. The wheels are normally rotationally supported on a shaft 4 and are spaced by stationary members 38 and the nesting relationship of the bearings, the bosses and the recesses 6, 8, 34, 32 is such as to support the wheels when the shaft 4 is withdrawn from the casing. The wheels are viewed at a window 20 below which a label may be fixed. Actuation and transfer.
