Patent GB-101080-A (GB)
Title: Improvements in Incandescent Lighting Means.
Filed: 1916-06-13
Abstract: 101,080. Svenska Aktiebolaget Gasaccumulator. July 30, 1915, [Convention date]. Oxyhydrogen and like lamps and burners. - In lime-light and like apparatus, t h e incandescent cylinder, disk, or the like, or the burner is moved automatically, by diaphragm apparatus controlled by an automatically operated gas valve so that the flame acts successively on different parts of the incandescent body. The movement may be intermittent or continuous, and may be a rotary or rectilinear one, or both. In one form, the incandescent body 3 is carried by a shaft 5 rotated through ratchet gearing 16 from a diaphragm 11, or from a valve 8 arranged in the diaphragm chamber 7 to control the escape of gas therefrom. The inlet 10 to the chamber communicates with the gas supply to the burner, so that the diaphragm is not operated when the gas to the burner is cut off. When the pressure of the incoming gas overcomes the pressure of a spring 12 on the diaphragm, the diaphragm rises and the valve 8 opens, thereby lowering the pressure in the chamber 7 and allowing the diaphragm to fall and close the valve. The Specification as open to inspection under Section 91 (3) (a) states that the diaphragm apparatus may be replaced by clockwork. This subject-matter does not appear in the Specification as accepted.

Patent GB-542805-A (GB)
Title: Improvements in variable leverage brakes
IPC: B61H13/24
Filed: 1940-05-21
Abstract: 542,805. Variable leverage brakes. CARLBOM, A. G. H., and SVENSKA AKTIEBOLAGET BROMSREGULATOR. May 21, 1940, No. 9039. [Class 103 (i)] Variable leverage brakes, particularly air brakes for railway vehicles, of the type having a low leverage ratio, effective only for taking up and producing shoe clearance at brake application and release respectively, and a higher leverage ratio, effective during that part of the brake piston stroke producing brake pressure, have, as shown for example in the Figure, a brake actuator such as the piston of cylinder 1, and a brake lever 2 connected to the piston head 1a and supported at a point 5a, determining a low leverage ratio, by means such as the knee-jointed levers 8 and 5 until the lever 5 is swung upwardly about a pivot 5b by means controlled by the movement of the actuator piston, whereupon the support point for the brake lever 2 changes to the point 6a determining the higher leverage ratio. In the construction shown there is a second brake lever 3 with a second brake pull rod 7 the levers 2 and 3 being connected by the lever 5 pivoted at 5b to the lever 3. The downward movement of the lever 5 to withdraw the support afforded at the pivot 5a to the brake lever 2 is effected by means of a bell-crank 10 pivoted on the piston-head and connected to lever 5 by a link 9, the actuation of the bell-crank being effected through a pin-and-solt connection to a lever 11 pivoted on the cylinder 1. A lever 6, which is pivoted to the brake lever 2 at 6b, provides another connection between the brake levers 2 and 3, the connection to lever 3 being through a pin-and-slot to provide a lost motion during the lower leverage operation; a device 13 is provided for adjustment of the amount of lost motion and this device is operatively connected to a servo-motor 15 operated by the cylinder 1, when the piston reaches a determined position, for preventing reversal of the lost motion at the change to the higher leverage. Modifications of the leverage change means are described, these also including forms with only one brake lever; in one modification the yielding support for the lower leverage pivot is a hydraulic cylinder with a valve controlled by means of a linkage system connected to the brakeactuating piston.

Title: Improvements in sheet delivery apparatus for printing machines
IPC: B65H29/04
Filed: 1947-04-08
Abstract: 628,158. Delivery apparatus; cylinder printing machines. BRITISH SALMSON AERO ENGINES, Ltd., and RANGER, A. W. April 8, 1947, No. 9319. [Classes 100 (i) and 100 (ii)] In a sheet delivery apparatus for a printing machine of the endless chain and mechanical gripper type the conveyor comprises two sections hinged at their adjacent ends so that each section can be raised about its hinged end independently of the other section. The conveyor comprises two sections 9 and 10 constituted by side frames 12, 13 and 14, 15, which are pivotally mounted on a shaft 11. The fore section 9 carries sprocket wheels 17 on a shaft 16 and the rear section carries sprocket wheels 19 on a shaft 18, chain 20 carrying gripper bars 25 and grippers 24 pass around the sprockets 17 and 19. The shaft 16 is driven by bevel gearing 61, 60 by a shaft 59 driven through bevel gearing 58, 57 by a clutch driven by further gearing 53, 52 and 50, 49 by the shaft 36 of the impression cylinder. In order to synchronise the speed of the conveyer grippers with the speed of the grippers on the impression cylinder a speed varying device, Fig. 5, is provided in the drive between the cylinder and conveyor. The speed varying device comprises a clutch in which a lug 66 on the wheel 57 is driven by a pin 64 on an arm 63, which rotates about an axis eccentric to that of the wheel 57. The arm 63 is slidably mounted on a shaft 54 and may be moved so that the pin 64 is disengaged from the lug 66 by raising a lever 70 against a spring 681. The lever 70 is raised by cams 74 and 73 carried on the fore and rear sections 9 and 10 of the conveyer, so that as each section is raised the clutch is disengaged, each section being maintained in the raised position by a counterbalance or a locking arrangement. By means of the speed-varying mechanism the speed of the shaft 11 and the chain grippers alternately increases and decreases relatively to the speed of the shaft 54 and thus to the speed of the impression cylinder. The mechanism is so arranged that the speed of the gripper chains is decreased as the grippers pass around the sprockets 17 so that the grippers are moving at the same speed as the cylinder grippers at the moment of transfer of the sheet and the speed of the chains continues to decrease until the previously printed sheet is deposited on a delivery pile. The sheets deposited on the delivery table are straightened by joggers 82, and 75. One jogger 75 is pivotably mounted by a lever 79 to the side frames 14 or 15 while the other is carried by a piston rod 76 sliding in a pneumatic cylinder 77 which is connected to a suction or compression air pump which operates the jogger against spring pressure. The jogger 82 may be operated in a similar manner. In a modification of the speed-varying mechanism the shaft 16 may be driven through a manuallyoperable clutch driven directly from the impression cylinder by gearing. Specification 589,522 is referred to.

Abstract: 287,882. Cattaneo, G. March 28, 1927, [Convention date]. Mounting gear wheels on shafts; shaft couplings.-A gear drive is shown in Fig. 2 by which cam shafts O and N operating the valves of an internal-combustion engine may be finely adjusted on the differential or vernier principle independently of one another. A gear F is connected to the shaft O by a toothed coupling E having, say, 21 teeth, while gears F and G have, say, 20 and 21 teeth respectively. If the gear F be disengaged and advanced one tooth upon the gear G and the coupling E be shifted back one tooth, the angular adjustment of the shaft O is <1>/420 of a revolution. By having a second differential arrangement at H, it is possible to adjust the shaft O without affecting the adjustment of a shaft N driven from it. According to the Specification as open to inspection under Sect. 91 (3) (a) the differential vernier coupling shown in Fig., 1 was regarded as part of the invention. The Specification also comprised an arrangement of two such couplings arranged in series. This subject-matter does not appear in the Specification as accepted.

At least one of the electrodes is preferably transparent, and the dielectric matrix is castor wax or triscresyl phosphate. An information storage and memory device using a number of electroluminescent cells is shown in Fig. 3.  A light source 34 initially illuminates all the cells to remove all the polarization which may be present and information is printed on selected specimen cell by successive pulses applied to one or more cells. The information stored is then read off by applying pulses of opposite polarity to the cells and recording the light output using a photo-cell 29 slidable along a track 30.  A rectangular array of cells containing n horizontal rows of m cells each, Fig. 4a (not shown), has their upper electrodes connected by n horizontal wires and their lower electrodes connected by m vertical wires.  Each of the m and n wires has an associated switch whereby it may be connected to a voltage source at a potential of + V, O, or - V volts.
