Title: Improvements in or relating to Photometry and to Apparatus therefor.
IPC: G01J1/08
Filed: 1917-09-29
Abstract: 112,614. Siemens & Halske Akt.-Gres. Jan. 12, 1917, [Convention date]. Photometric apparatus; colorimeters.-In photometric apparatus for the comparison of lights of different colours, means are provided by which the colour of the rays from one source of light may be varied without variation of their total illuminating power. As shown in Fig. 1, a standard light l is enclosed in an internally whitened casing g having ground glass disks m1, m3, and red, green and blue colour screens f1, f2, f3 respectively, of equal absorbing power, between it an another casing k having a frosted glass disk m. Slides s12, s23 are separately adjustable over each pair of filters to vary the colour of the rays passing to the casing k, and are of such width that the total effective area of the screens is constant. In a modification, the colour screens are arranged at angles of 120 degrees relatively to one another and a single shutter movable horizontally in a frame movable vertically varies the effective area of each screen without varying the total effective area. The colour screens may be relatively weak so that a considerable amount of white light may pass through them, or the screens may only cover the light passage in part for the same purpose. Where the colours of the lights to be compared do not differ widely, the green screen may be omitted. Fig. 3 shows an apparatus in which red and bluegreen screens fr, fg respectively are spaced apart in a frame r6 adjustable by means of a screw spindle s in front of a frosted disk m6. The total effective area of the screens and of the space permitting unfiltered light to pass remains constant in all positions of the frame r6.

Title: Portable device for applying a clip or staple around the gathered end of a bag, casing or like container
IPC: A22C11/12
Filed: 1965-04-02
Abstract: 1,074,925. Closing filled bags. RHEEM MANUFACTURING CO. April 2, 1965 [Oct. 1, 1964], No. 14118/65. Heading B8C. A device for applying a permanent fastener around a container, e.g. a bag or casing neck, includes a housing formed with a track for clips, having a fixed die at one end, a reciprocable punch, lever means mounted on the housing to drive the punch towards the die, and detent means operatively connecting the punch member and lever means for holding the punch in a retracted position. The casing end is introduced via a throat (60), Fig. 3 (not shown), to a die (28). A track (22), into which the clips (29) are fed from a magazine 20, reciprocably receives a punch (25) secured to a rod 45, spring-loaded toward the die (28). On manual withdrawal of the punch, using a gripping knob 48, against the pressure of spring 52, a clip (29) enters the track (22), the punch being held in its retracted position by a member 53 entering a detent groove 55 in the punch (25). The member 53 is carried by a lever 11, pivoted at 10. The lever, and member 53, are urged by a spring 56 in an anti-clockwise direction. By moving the lever 11 away from the housing, the punch is sprung forward, forcing a clip along the track (22) to the die (28), impact being minimized by the action of a spring 59. The lever is now gripped to move it towards the housing, link member 53 abutting the punch 55 at 63 to force it forward, and hence force the clip (29) against the die (28) and around the casing end. The die face carries two channels, the track (22) and punch (25) being slantingly disposed to the horizontal to permit one leg of the clip to enter each channel. The magazine 20 is complementarily slanted, Fig. 7 (not shown), the arrangement causing the clip to be bent to helical form. The fastened casing end is withdrawn by the downward displacement of a spring-biased guard plate 32.

Title: Improvements relating to electric signalling torches
IPC: G09F21/02
Filed: 1955-05-18
Abstract: 792,967. Coloured signalling torches; lantern screens. NAM, Y. May 18, 1955, No. 14402/55. Classes 39(2) and 75(4) An electric torch with one or more coloured screens for projecting light of different colours comprises a two-part casing or housing for a battery and lamp bulb arranged so that relative movement between the two parts of the housing causes a coloured screen to be moved to a position in front of the bulb Switching may also be effected by relative movement of the said two parts of the housing which is preferably cylindrical, so that relative axial movement effects switching and relative rotary movement produces the colour change. In the example a bulb-enclosing end part e of a cylindrical casing has a screw-threaded bezel h whicl maintains a reflector f and a lens g in position above the bulb i which is mounted ir a socket on the upper end o: the battery-enclosing part a. Screens j and k of trans parent plastic material, which may be green and red respectively, are located normally at opposite sides of the bull i each upon an arm l mounted on a single common pivo m carried by a lug n extend ing upwardly from the part a and beside the bulb socket The laterally projecting end: of a circular coil spring ( engage the respective arms l and tend to maintain them in their inoperative position. Each arm l has a lug or projection s Fig. 4, extending from it towards the wall of the part e of the casing, each lug being adjacent to one of a pair of contact pins p projecting inwardly from the said part e, so that when the latter is rotated in one direction or the other relative to the part a, on which it is a push-fit, a pin p engages the adjacent lug s of a screw-carrying arm l and swings it in opposition to the spring o to bring the associated coloured screen to a position before the bulb i. The rotative movement is limited by providing the lower portion of the wall of the casing part e with an inverted T-shaped slot t which receives a pin u projecting from the lower casing part a. A locking-position which prevents inadvertant axial movement of part e relative to part a is provided by a lateral notch at the top of the slot t to receive the pin u at a position v, Fig. 2. Switching is effected by first rotating the head part e slightly to free the pin u from its locked position and then moving the head axially outwardly to bring the pin into the position w, at which the contact pins p engage the lugs projecting from the screen holders l, so that the bulb is switched, on and a clear light is emitted. Clockwise rotation of the part e of the casing relative to the part a brings the pin u to the end position x of the slot t and causes a pin p to swing the screen f in front of the bulb. whereas anti-clockwise rotation of the part e brings the screen k to that position.

Abstract: 686,192. Quick-release parachute fastenings. AIRCRAFT MATERIALS, Ltd., and GOULD, G. H. Sept. 7, 1951 [June 12,1950], No. 14615/50. Class 44 A quick release fastening for parachute harness comprises a box containing a number of spring- loaded plungers having inclined end surfaces adapted to be operated upon independently to displace the respective plungers and permit insertion of a number of fasteners into the box, and means are provided for operating on the inclined surfaces simultaneously to displace the plungers and release all the fasteners together. In the form shown in Figs. 2 and 4, the box comprises a base plate 1, a plunger guide plate 2, a plunger lifting plate 3, a plunger housing member 4 and an operating member 5. Four plungers 6 have inclined end faces 6a co-operating with the usual apertured lugs on the ends of the harness straps. Simultaneous retraction of the plungers is effected by rotating the operating member 5 and the plunger lifting plate 3, which has four apertures 8, Fig. 2, having cam surfaces 8a which on rotation of the plate engage the inclined ends of the plungers and lift the latter. The plungers can be locked in the fastening position by depressing the operating member 5 into the position shown in the right hand part of Fig. 4, when the springs 13 are fully compressed. The plunger lifting plate 3 is rotated by operation of member 5 through pins 21 on upstanding lugs on plate 3 which are normally engaged in slots 22, Fig. 7, in the skirt of member 5. On depressing member 5 to lock the plungers, pins 21 pass into circumferential grooves 23, and member 5 can be further rotated independently of plate 3 until pins 21 engage in depressions 26. Successive release of the strap lugs may be arranged if desired by varying the positions of the cam surfaces in plate 3. In a modification, the plungers are formed integrally with a plate 30, Fig 9, having a central aperture 31, the edge of which bears against a curved shoulder on a central boss so that plate 30 can rock or tilt. A positive action of the operating member 5, Fig. 10, into released or locked position may be arranged by the provision of an overcentre spring device comprising a pair of coiled springs 32, 33, one end of each spring being pivotally mounted on a peg 35 or 36 carried by a plate 34 which is fixed in relation to the base of the box, the other ends being pivotally connected to a lever 39 centrally pivoted in plates 34 and 40, and turned by member 5 through a square boss 39a.
