Title: Improvements in or relating to electric selecting mechanism
IPC: A63F1/14
Filed: 1937-03-31
Abstract: 494,901. Valves. SWAN, J. C. K., and ROY, H. B. March 31, 1937, Nos. 9223 and 14079. [Class 135] [Also in Groups XV and XXXVII] Pneumatic selecting mechanism, particularly for use in connection with games, comprises a socket 1 into which any of a plurality of balls 15 of a number of different sizes can be introduced, the width of the socket varying progressively along its length so that the balls are restrained at different points, and means 14 disposed at each such point controlled by a ball so as to actuate one of a corresponding number of devices. Fifty-two metal balls of four different sizes are supplied to a dish 16, Fig. 4 (shown in an electrical modification), which is rotated by a motor 81 thereby causing the balls to fly outward, and to be held in a serrated member 18 rotating with the dish 16, a stationary finger 19 assisting in evenly distributing balls. On coming to rest, the serrations 18 are registered with a series of tapered sockets 1 by means of a detent 25 which is pushed into an indented rim on the rotary member. A cam on a shaft 52 then operates a lever 49 to lower the dish 16, whereupon the balls fall into the sockets and are arrested at certain levels according to their size. As shown in Fig. 2, the keys 131 are operated pneumatically, a ball, on entering a socket, being adapted to close the mouth of one of four suction tubes 123 and thereby creating a vacuum to operate a piston device to indicate the card that may be played. This is done by depression of the raised key 131 which thus raises a tablet 137 denoting the card played.

Abstract: 1,153,644. Electrical plug pins. FLAGGRAND Ltd. 21 Feb., 1968 [28 Feb., 1967], No. 9458/67. Headings B3A and B3K. An electrical plug pin is produced by cutting a length from an extruded electrically conductive strip whose cross-section corresponds to that of the proposed plug pin, and deforming one end of the strip to form one or more integral, lateral projections. One preferred method uses a circular saw assembly 2 wherein a large diameter saw 3 makes a severing cut and a small diameter saw 4 a partial cut to leave one or more uncut portions 6, the two saws being mounted coaxially together, the portions 6 are then bent to form the lateral projections. Alternatively, the projection may be formed by punching one end of the length in a die by means of a punch along the longitudinal direction causing a part of the metal to flow outwards, or else one end of the length may be twisted so that the edges of the twist portion project over the sides of the length.

Patent GB-599819-A (GB)
Title: Improvements in or relating to double exposure prevention mechanism for photographiccameras
IPC: G03B17/42
Filed: 1945-04-17
Abstract: 599,819. Photographic cameras. KODAK, Ltd. April 17, 1945, No. 9577. Convention date, May 13, 1944. [Class 98 (i)] Double exposure prevention mechanism comprises two pivoted levers adapted to engage between a fixed shoulder and a slidable collar on an axially slidable shutter-actuating member in order to prevent a shutter operation and operable by a cam, which is continuously rotated during the film winding movement to move the levers from this engagement and permit a shutter operation during which the collar is moved to permit either or both levers to re-engage between the shoulder and the slidable collar on release of the shutter-actuating member. As shown, in Fig. 1, in a housing 40 on the camera wall 38 are levers 48, 49, pivoted at 50 and having spring metal arms 54, 55 which are spring-urged at 51 into contact with a cam 45 mounted on the film winding shaft 11 and having a high point 46. The shutter is of any known type, and is actuated by a rod 34 having a press-button 22, a fixed shoulder 73 and a slidable collar 60, which is urged by a spring 70 into engagement with a fixed flange 72, Fig. 16. With the camera ready for an exposure, the button 22 is pressed, moving the rod 34 to actuate the shutter and stress the spring 68, the shoulder 73 entering and pressing on the collar 60 during this movement to stress the return spring 70 and the lever arms 54, 55 resting idly on the periphery of the button 22. On releasing the button 22, the rod 34 and collar 60 move outwards and the arms 54, 55 slide along the button 22 until the collar 60 is arrested by the flange 72, while the rod 34 continues to move, thereby opening a gap between the shoulder 73 and collar 60 into which the arms 54, 55, or one of them, drop, depending on the position of the high point of the cam. In this position, further actuation of the shutter is prevented since the arms, or that one which is in the locking position, strike the camera wall and prevent sufficient depression of the button 22 to release the shutter. On winding the film, however, the cam 45 rotates and its high point 46 successively rotates the levers so that the arms 54, 55 are moved into the inoperative position shown in Fig. 9. Rod 34 can now be moved inwards to effect another shutter operation. A modification is described which is designed for a camera in which the shutter button and film winding knob are adjacent. The Specification as open to inspection under Sect. 91 describes a shutter consisting of a shutter blade and cover blind, which are actuated by a pin on the rod 34 so that apertures therein register to allow an exposure ; a slidable diaphragm with a smaller aperture may be provided. This subject-matter is not contained in the Specification as accepted.

Class 8(2) A liquified gas e.g. butane container 1, Fig. 1 is connected to a gas discharge duct 7 through a two-way valve 3 and a pressure relief valve 6, and a reserve container 2 is connected through a two-way valve 4 to the inlet of a pressure relief valve 5 operable at a lower pressure than is necessary for the valve 6 and which discharges to the inlet of said valve 6; the valves 3, 4 being changed over simultaneously to the position shown in Fig. 2 when the container 1 requires renewing and thereby maintaining substantially without interruption supply of gas to the duct 7. In normal operation valve 5 remains closed, but as the container 1 becomes empty valve 5 opens to effect discharge of the reserve container 2. In a modification the two-way cocks 3, 4 are each replaced by a pair of disc valves, and two pressure relief valves 5 are pro-. vided in parallel. In a further modification the two-way cocks comprise. piston valves and the pressure relief valves 5, 6 are housed in a single casing.

Patent GB-975568-A (GB)
Title: Data storage systems
IPC: G06F7/38
Filed: 1961-03-16
Abstract: 975,568. Digital data storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 16, 1961 [March 23, 1960], No. 9622/61. Heading G4C. [Also in Division H3] Digital data is stored by establishing a discontinuity in a conductor of electric or ultrasonic waves, the time interval between transmitting an input pulse along the conductor and receiving a reflected pulse representing the digit value. In Fig. 4 the conductor is a delay line having a central conductor 6 of high remanent steel. At a selected point a coil 9 is wound on an insulator 10 surrounding the delay line. A current through the coil 9 saturates the remanent steel between the broken lines and the resultant magnetic field sets up a discontinuity in the line. The pulse may be a packet of sinusoidal waves in which case the length of time embraced by the coil is an odd number of quarter wavelengths so that the reflected waves at each end of the coil combine additively. The conductor 6 may be effectively non-remanent in which case the coil 9 is wound on a cylinder of high remanent steel enclosing the insulator 10 (Fig. 5, not shown). Removal of the discontinuity may be by applying to coil 9 a sinusoidal current of decreasing amplitude, or D. C. current which reduces the magnetic flux of the saturated region or cylinder effectively to zero. If the latter method is used, a bias current may be permanently applied to the coil and the erasure current saturates the remanent material in the opposed state. The discontinuity may be in the form of a short circuit. Fig. 13 shows the ends 202, 203 of a coil wound on the delay line, which are each dipped in iron filings forming a coherer rendered conductive by a current through leads 204, 205. In Fig. 14, the transmitted signal is an ultrasonic pulse, and a cylinder of high remanent material 214, surrounded by coil 215, encloses part of a magnetostructive line 211. An ultrasonic pulse is generated by energizing coil 213 and the pulse reflected by the pressure change in line 211 caused by the remanent state of a selected cylinder 214 is converted to electric energy by coil 216. Coils 213 and 216 may be combined. Fig. 12a shows one order of a three word data store. Each delay line L1 to L3 stores a decimal digit. To read-out L1, a signal is applied to line 105 and to line 103 which opens gate 121 to a set of counting pulses on line 102. A generator 120 applies a pulse to line L1 by way of line 123 and counter 134 is started. The reflected pulse stops the counter by passing through triode 131 and closing gate 135. If the complement of the value stored is to be read out, the read pulse is applied to the other end of L1 on line 124. To write, the counter 134 is set to the required value and line 104 and an appropriate one of lines 108 to 110 are pulsed. A comparison between digits stored in different lines can be made by comparing the read-out times of reflected pulses without actually assigning values to the respective time intervals.
