Patent GB-250775-A (GB)
Title: Improvements in and relating to machines or apparatus for dividing off and packing predetermined quantities of ice-cream or similar plastic material
IPC: B65B57/06
Filed: 1925-05-14
Abstract: 250,775. Lyons & Co., Ltd., J., and Coyte, W. A. May 14, 1925. Filling ice-cream and like plastic materials into boxes.-Apparatus for dividing off and feeding predetermined quantities of plastic material into boxes, and having feed apparatus held inoperative by controlling. mechanism adapted to be operated by the passing of a container into position, is characterized by the material being fed by a cylinder, the reciprocating piston of which has continuously operating mechanism adapted to be rendered operative by such controlling mechanism. As shown, the ice-cream is contained in a hopper 2 and is forced towards the outlet 3 by a paddle 5, pivoted on an arm 7 so as to be held rigidly with the arms during the strokes towards the outlet, and to be free to rotate during the return stroke. A cylindrical delivery valve 4 is rotated in a sleeve 23 below the outlet bv a spur wheel 26 and a quadrant operated by links 30, 31 and a cam-operated. lever 32. A piston 40 is operated to withdraw material through the outlet 3 when the valve is open to the hopper and to expel it through an opening 39 into a box 10 when the valve turns to its other position. The piston is operated by a lever 42 connected bv a, rod 48 to an eccentric 49 and co-operating with the piston rod by means of pawls 43, 44 adapted to engage with abutments 50, 51. The valve and piston are normally inoperative owing to a. lever 53 with a catch 55 engaging an extension of the leevr 32 and holding it out of engagement with the cam 36. The valve is therefore not operated by the links 30, 31, and a link 58, on an extension 57 of the lever 32, by means of a bell-crank lever 59, causes the pawl 43 to be lifted out of engagement with the abutment 50, and the piston therefore does not move. If, however, a box 10 is fed by endless chains 11 beneath the hopper 2, it pushes aside the lever 53 and causes it to disengage the lever 32 and the machine is set in operation. The box may be lined and the flaps may be held by guides clear. of the mouth.

Title: Improvements relating to automatic setting devices for exposure factors in cameras
IPC: G03B7/083
Filed: 1952-05-20
Abstract: 711,664. Photographic cameras. DECKEL, H., and DECKEL, F. W. May 20, 1952 [June 29, 1951], No. 12728/52. Class 98(1) [Also in Group XL(b)] A device for adjusting camera exposure in accordance with incident light film speed &c. comprises a resistance bridge one arm of which is. situated beneath the pointer of a photo-electric exposure meter so that when the shutter release is pressed the pointer contacts the wire any out-ofbalance current across the diagonal of the bridge being used to set the first exposure adjusting factor which also adjusts another arm of the bridge so that when the bridge is rebalanced the shutter is operated. As shown, light received by a photo cell 3 adjusts the position of the pointer of a moving coil meter. This pointer is brought into contact with a resistance 6 forming two arms of a resistance bridge by means of a plate 5 depressed by the shutter release button. The other two arms are constituted by a resistor 9 mounted on a carrier ring 43 which carries pointer 21 indicating aperture setting. The time setting ring is read against a fixed pointer 25 and carries a resistor and wiper arm 23, the position of which relative to the time ring may be adjusted to take account of film speed. Either the time or aperture rings may be geared to a drive 13. When the bridge is out of balance, pressure on the release button 26 supplies current to the bridge, and a moving coil relay 14, connected across its diagonals closes one of contacts 36 to drive either the time or aperture ring through means 13 until the bridge is again balanced. Meanwhile a relay 18 is energized to hold off delay action shutter release relay 20 which thus operates only when the bridge is in balance. The driving means 13 may be spring or motor operated or may be adjusted by a step-by-step mechanism. The spring drive may be linked to the carrier shutter setting or film speed mechanism. An arrangement is described, Fig. 3 (not shown), in which the time and aperture rings are stepped by a self-interrupting magnet, the rings being returned by a spring released by a magnet operated when the push button is released. If a filter is necessary the apparatus may be corrected by providing another filter in front of the photo cell or, Figs. 4, 5 (not shown), the filter holder carries a wedge-shaped pin which adjusts the position of the aperture ring relatively to its pointer. Shutter release button 26 may be used to set the driving mechanism 13. As the button is depressed its nose 54 slips past a spring loaded lever 56. As the button is released its nose rocks the lever anticlockwise momentarily closing contacts 57 which through an electromagnet system wind the spring of the driving mechanism.

Filed: 1922-05-08
Abstract: 206,865. Roe & Co., Ltd., A. V., and Chadwick, R. May 8, 1922. Framemork.-The framework of the fuselage of an aeroplane is constructed of members tapered in such a manner that the strength of the framework is greatest where the greatest load is to be carried. The invention is described as applied to a fuselage constructed of tubular metal longerons 1 and cross-bracing tubes or struts 3. The section of the framework carrying the greatest load is formed of longerons 4 of uniform diameter, but the longerons 1 extending from this section to the tail are of taper formation, their diameter at each bay being such as to accommodate the load to be carried there. The longerons 1 may be connected to the longerons 4 by means of detachable joints or the longerons 1 may be formed in sections with detachable joints. to facilitate transport of the fuselage. The crossbracing tubes 3, which decrease in diameter towards the tail, may be tapered at one or both ends or they may be of the same diameter throughout their length. According to a modification, the taper of the longerons may extend from the head of the fuselage in which case the longerons 4 of uniform diameter are dispensed with. Reference has been d,irected by the Comptroller to Specifications 130,997 and 143,864.

Abstract: 289,886. Kodak, Ltd., (Assignees of Wittel, 0.). May 5, 1927, [Convention date]. Lens mounts; iris diaphragms; colour filters.- Lens mounts and their attachments, such as colour filters and telephoto lenses, are constructed so that they can only be operatively connected when they occupy a predetermined position. Thus, a. graduated colour screen is arranged to occupy a. definite angular position, a colour screen requiring a large aperture is only attachable when the aperture is properly adjusted and similarly with regard to a telephoto lens. In one form. the diaphragm of the lens consists of a rotatable disc having the various apertures, and adjacent to these apertures are shaped holes adapted to receive a projecting portion on the mount of the colour filter or telephoto lens. In another construction, Fig. 5, a colour filter M is carried in a mount L inserted into the forward part of the lens mount H and held in place by a spring ring. Attached to the filter mount L is a projecting strip L', the upper half of which slides in a groove in the lens mount H and the lower half in the rotatable sleeve J<1> by which the iris diaphragm is actuated. The filter M can thus only be attached in a particular angular position and when the diaphragm is open to a particular aperture. When in position the strip L' locks the diaphragm in its selected position. A further form is described with reference to sliding diaphragms.
