Title: Improvements in or relating to devices for the regulation of respiratory apparatus
IPC: H01H43/12
Filed: 1964-05-26
Abstract: 1,073,712. Respiratory appliances. SOC ANON DES LABORATOIRES ROBERT & CARRIERE. May 26, 1964 [Sept. 11, 1963], No. 18687/64. Heading A5T. [Also in Divisions G3 and H2] A control device for use with an electrically driven apparatus for giving artificial respiration is operable to vary the number of respiratory cycles per minute and to adjust the duration of the respiratory phases. The respiratory apparatus includes two pumps, one of which supplies an adjustable volume of gas to the patient's lungs and the other transfers gas from the patient's lungs to the atmosphere, while an electric motor driven at constant speed is connected through a reduction gear to electromagnetic clutches which are operatively connected to connecting rods operable to actuate the pistons of the pumps. In the control device, spindle B, which carries cam E, is driven by electric motor R through reduction gear D so that each rotation corresponds to one complete respiratory cycle. Microswitches G, G1 G2, G3, respectively, are mounted on gear wheels F, F1, F2, F3, each of which is rotatably adjustable relative to spindle B by a knob, e.g. K1, connected to a pinion which meshes with the gearwheel F1, and thus adjusts the microswitch G, to a desired angular position relative to the spindle B. Microswitches G, G1, G2, G3 are connected to relays, e.g. I1, which control pumps 3 and 4 and valves 9 and 10 respectively. As the cam E is rotated, it contacts the four miscroswitches G, G1, G2, G3 in turn, thus controlling the pumps and their associated valves to produce a desired respiratory cycle.

Title: Improvements in or relating to liquid supply apparatus
IPC: B01L3/02
Filed: 1964-05-08
Abstract: 1,059,654. Bottling. J. M. L. DE BAETS. May 8, 1964 [May 9, 1963], No. 19330/64. Heading B8T. An electrically controlled liquid supply apparatus for filling test tubes includes a carrier 20 for test-tubes 19 intermittently movable in the direction of the arrow 23 beneath liquid supply nozzles 17, and each transverse row of nozzles, which is arranged to correspond with a similar number of test-tubes, is fed from a constant level tank 8 via a syphon tube 13, valve 14 and pipes 15, 16. Each tank is supplied from a vessel 4 through a valve controlled pipe 5. The carrier moves intermittently down a slide 22, and at each stoppage a row of test-tubes is located below a row of nozzles, whereupon an electromagneticallycontrolled liquid supply valve at a location 61, Fig. 2, in the appropriate pipe 15, is automatically opened and liquid flows for a regulable period of time. The slide is adjustable in the direction of movement and, depending on its position, operates one of a series of switches, equal in number to the number of vessels 4, whereby the appropriate electromagnetically-controlled valve in one of the pipes 15 may be opened when the carriage comes to rest. As shown, there are eight vessels and supply tanks and eight slide positions. Windows 42 with indicating lights indicate from which tank liquid is being supplied. When the carrier and slide are in their appropriate positions with the rows of nozzles and test-tubes aligned a main switch is manually operated and the appropriate electromagnetically-controlled liquid supply valve automatically opened. Simultaneously, a magnetic coupling 31, Fig. 4, is energized which connects a spring-loaded lever 32, Fig. 5, to the drive of an electric motor 28. The lever is thus driven from a rest position, determined by the position of a knob 37, in the direction of the arrow 33 and operates a switch 49 which closes the liquid supply valve. In order to vary the time taken for the lever to move to operate the switch, and hence the liquid supply period, its rest position is adjusted by moving the knob towards or away from the switch. The operation of the switch by the lever also effects the energizing of a coil 51, Fig. 4, which attracts a lever 52; the end 54 of the lever is withdrawn from one of a series of notches in the carriage 20 so that the carriage is able to move by gravity down the slide. Simultaneously, the end 56 of the lever 52 operates a switch 47 which cuts-off the magnetic coupling 31, and the lever 32 returns to its rest position and the switch 49 is returned to its initial position. When the end 54 of the lever 52 enters the next adjacent notch in the carriage, the switch 47 is released from its contact with the other end of the lever; in this further position of the carriage a fresh line of test-tubes is aligned with the appropriate nozzles and the cycle of operations is automatically repeated. When the carriage reaches the end of its travel on the slide, it operates a further switch to stop the apparatus.

Abstract: 1,042,456. Endless conveyers. OERLIKONBUHNLE HOLDING A.G. May 16, 1963 [June 4, 1962], No. 19609/63. Heading B8A. [Also in Division F3] In a magazine for a rocket projector, the rockets are conveyed from a magazine loading aperture 9 to a drum 4 for insertion into the loading chamber 5 of the projector, by means of two or more endless chain conveyers 19, 20 arranged one above the other and having protruding dogs 45a for moving the rockets along zig-zag-shape curved guides 8, star-wheels 16  being provided for transferring rockets from one chain 19 to the other 20 and reversible driving means, e.g. an electric motor, provides a drive connection between the star-wheels 16, chains 19, 20 and drum 4. Additional driveconnected star-wheels 44, 14 are provided at opposite ends of the conveyer 19. The arrangement of chains and star-wheels shown is duplicated to engage each rocket at two spaced  points along its length. The drive connections are such that the rotational velocity imparted to the star-wheels 16 gives a lateral velocity to the rockets slightly larger than the speed of the conveyer chains and the rotational speed of the drum 4 is about 1¢ times that of the star-wheels 14, 16.

Title: Improvements in or relating to the manufacture of mosaic screens
IPC: H01J29/43
Filed: 1945-07-31
Abstract: 628,954. Coating with metals. CASSMAN, H. July 31, 1945, No. 19567. [Class 82(ii)] [Also in Group XL(a)] A method of evaporating a thin film of substance on to a support comprises simultaneously evaporating the substance on to a separate target, and the target and support are so positioned that the target receives a thicker deposit than the support, evaporation being discontinued when the deposit on the target is observed to have a predetermined thickness. The thickness of the deposit on the target is estimated visually, e.g., a 50 per cent transparent film of silver has a blue colour, or by means of a light beam passing through the target to a photocell. The method may be used in the manufacture of a signal plate in a television transmission tube but is preferably used in the manufacture of a photo-sensitive mosaic in which the known process consisting in (a) the deposition of a thin layer of silver, (b) oxidizing the silver layer and treating with calcium, (c) the deposition of a further thin layer of silver, is employed. In Fig. 1, the first layer of silver is deposited from heaters 8 on a sheet of mica 2 and simultaneously on one or two glass or mica targets 11. The frame carrying the heaters 8 is collapsable to facilitate insertion into the envelope. The heaters 8 carry a sufficient quantity of silver for a subsequent deposition so that two pairs of heating coils are not required as in the prior art process. The heaters 8 are degassed before insertion into the envelope in a demountable degassing chamber, or they may be degassed after insertion into the envelope in which case they are enclosed by movable flaps (not shown) during degassing to prevent random deposition on members 2, 11. The target or targets 11 may also be used to indicate the course of the treatment of the silver deposit with calcium. The Provisional Specification refers to the application of a plurality of further layers of silver and states that metals or materials other than silver and calcium can be used.

Abstract: 143,942. Gray, J., (Hewett, J. R.). Nov. 27, 1918. Breach mats. - A breachmat device comprises a number of pivoted beams or rods 1 which, when released, move into a vertical position, and over which a mat 2 with horizontal reinforcing-sections is adapted to be unrolled so as to cover a hole in a ship's hull. The rods- 1 are normally held in the horizontal position by catches 9 releasable by a cable. Each group of rods on either side of the pivots is connected by a cable 16 operated by a drum 17, the rods of each group being connected together by links 8. The lowering operation is also controlled bv cables attached to the outside rod members. The mat is unrolled over the verticallyarranged rods by the operation of the shaft 25, whereby the oppositely-rotated windlasses lower and pull the cables 21, 26 respectively supporting and attached to the lower end of the breach mat. This arrangement provides means for keeping the mat, during the lowering operation, under constant control, and secures it to the vertical rods when in the unrolled position. The mat is secured as a whole by chains which go round the vessel. A member 3, pivotally mounted by links 38 to a carriage 37, supports the mat and rod members, and the carriage 37 is adapted to travel on rails 7 secured to the sides of the vessel, so that the mat device may be readily transported into any desired position.
