Title: Improvements in or relating to devices for producing low-voltage electric pulses
Inventor: GREEN KENNETH REID
IPC: H03K3/00
Filed: 1960-03-30
Abstract: 898,422. Counters. LANDIS & GYR Ltd. May 30, 1961 [March 30, 1960], No. 11217/60. Class 106 (1). A circuit for counting each closure of a contact 11 comprises a low-voltage cell 9 and a counter-operating-solenoid 13 in series with the contact 11 and is characterized in that the cell is maintained charged by a rectified A.C. supply. The circuit is said to be particularly useful in transmitting indications from electricity consumption meters to a distant counter as the pulses which have to be transmitted are of low-voltage so that heavily insulated cable is unnecessary.

Title: Improvements relating to variable gain amplifiers
Inventor: NEWMAN EDWARD ARTHUR
IPC: H04N5/202
Filed: 1948-04-24
Abstract: 649,793. Non-linear valve circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd. April 24, 1948, No. 11313. [Class 40 (vi)] In a variable gain amplifier of the kind described in Specification 497,060, having an impedance which varies in dependence upon a characteristic of the input signals, and thus varies the gain in dependence upon this characteristic, and in which reactance shunting this impedance produces undesirable modification of the frequency response, a further reactance is added to compensate these undesirable changes. As shown, input signals from a source 3 are amplified by a valve 1 and an output is obtained between terminal 11 and earth. A second valve 2 passes between a conducting and a non-conducting state when the amplitude of the input passes through a certain value and alters the impedance in the cathode circuit of valve 1. The cathode to ground capacity of the valves indicated by condenser 20 affects the frequency response and is compensated by the insertion of condenser 12 as shown.

Title: Improvements in or relating to photographic shutters
IPC: G03B9/22
Filed: 1939-04-14
Abstract: 527,728. Photographic shutters. KODAK, Ltd. April 14, 1939, No. 11334. Convention date, April 16, 1938. [Class 98 (i)] The trigger of a setting-type photographic shutter normally occupies an inoperable position, and is moved to the operable position when the shutter is set by the setting lever, the user being thereby warned when attempting to make an exposure with an unset shutter. In the shutter shown, the pivoted master member 12, which operates the blade ring 5 through a latch 9, is set against the action of a spring 14 by means of a setting lever 17 which carries a pin 20 engaging in a slot in the member 12. The lever 17 is carried by an arcuate plate 18 slidably mounted in a similar slot 19 and carrying at one end a bearing 27 for a spring-pressed curved pin 28 which during movement of the parts to the " set " position shown, engages by its head 30 a lug on the release trigger 24 and turns it against the action of a spring 32 so that it latches the member 12. On release of the shutter, the arcuate plate 18 moves to the left so that the pin 28 no longer contacts with the trigger 24, and the latter is retained by the spring 32 at the limit of its downward movement so that it cannot be operated. A release on the camera body may be used, which is also retained in inoperative position when the shutter is not set. As shown in Figs. 3 and 4, the trigger 24 is connected by a finger bar 48 to a lever 47 pivoted coaxially with it on the back of the shutter casing, and a rod 43 connects the lever 47 to a lever 42 the end of which engages in a collar 40 on the spindle of the body release 36.

Patent GB-817073-A (GB)
Title: Improvements in or relating to liquid fuel burners
Inventor: IMBER ALFRED GREGORY
IPC: F23D5/00
Filed: 1956-04-16
Abstract: 817,073. Liquid fuel burners. IMBER RESEARCH Ltd. March 18, 1957 [April 16, 1956; May 29, 1956; Oct. 22, 1956], Nos. 11516/56, 16596/56 and 32148/56. Class 75(1) A liquid fuel burner comprises a central air supply tube 2a, an annular vaporizing trough 1a surrounding the tube and into which a controlled fuel supply is introduced as through a conduit 3a, and a deflector 5 spaced from the exit of the tube 2a which is adapted to deflect at least a portion of the air in the direction of the trough to cause part of the flame to be deflected back to produce the heat necessary for vaporizing the fuel. The portion of the deflector 5 lying inwardly of the down-turned edge is perforated with a ring of holes 6 so that a portion of the air only is deflected. A second deflector plate 7 receives and deflects the air passing through the deflector 5 and a third deflector plate 9 with holes 10 receives and deflects secondary air passing through holes 8 in deflector 7 and discharges " tertiary" air through the holes 10. The holes in the deflectors are smaller the greater the distance the deflector is from the exit of the tube 2a, and the holes in any one plate are staggered with respect to those in the other plates. The plates are correctly spaced by screw nuts 13 on a rod 11 guided in a spider 12. A ring 14 on the upper portion of the trough above the level of the deflector 5 with its underside below the level of the top deflector 9, produces a turbulent flow of hot gases. The fuel containing portion of the trough preferably has upwardly flaring sides 1a whereby increased height of fuel level above the bottom of the trough results in increased liquid vaporization surface which produces stable burner operation. The complete burner may be enclosed in a cap having a central aperture and carried by the vaporizing trough. The wall of the trough may be double to allow air drawn through ports 16 in the pipe 2a to pass over the inner wall 1a through ports 17 above the liquid fuel surface. Alternatively the outer wall 15 may be replaced by a series of tubes from ports 16 to ports 17. The trough may contain a wick or a gauze ring may be incorporated in the trough to break up the vapour.

Patent GB-494240-A (GB)
Title: Improved method of, and means for, attaching insulating board or other sheets or slabs to purlins or other frame members
IPC: E04B9/24
Filed: 1937-04-22
Abstract: 494,240. Fastenings. INKLEY, B. April 22, 1937, No. 11543. [Class 44] Boards are attached to purlins by one or more latches pivotally mounted on the side of the board adjacent the purlin when in position, the latches being disposed clear of the purlin prior to placing the board in position and being adapted to be rotated from the side of the board remote from the purlin when in position by means of the pivot member, which is adjustable to accommodate boards of various thicknesses. A latch 1 is pivoted on a board A by means of a bolt having a slotted end 16 in which a screwdriver can be inserted to operate the latch. An upwardly bent portion 14 of the latch 1 engages a flat on the bolt head 12 to ensure that the latch turns with the bolt and a turnedin end 10 provides a seating to produce a more even distribution of pressure when the latch is clamped by the nut 18. The part 8 of the latch is given the same inclination as the face of the purlin 20 which it engages. In a modification, for enabling an adjacent board to be attached to the board A, the end 10 of the latch is turned outwardly instead of inwardly, and extended, a tapped hole being formed in the extension to receive a screw passing through the adjacent board. The embodiment shown in Fig. 1 may be used for attaching a beam to a girder, the bolt being long enough to pass almost through the beam which is recessed to accommodate the nut and washer. In a modification, Fig. 4, the latch is formed so that the board is spaced away from the purlin when in position.
