Abstract: 528,936. Air-break switches. BRITISH THOMSON-HOUSTON CO., Ltd. May 17, 1939, No. 14734. Convention date, May 17, 1938. [Class 38 (v)] An H.T. air isolating switch comprises a pair of spaced fixed insulators 2 supporting pivotallymounted arms 3 which carry co-operating contacts at their ends, each arm having driving means therefor located in the head 4 of the appropriate insulator 2. Each contact may be located in an extinguishing head 6 serving to direct a blast of gas at the arc formed between the separating contacts. The arms 3 may move in a horizontal or vertical plane and may be of light metal such as aluminium alloy. To allow for inaccuracies in the mounting of the arms, these may be adjustable in the heads 4, or the latter may be adjustable in the insulator caps 7. The cap 7 may be in the form of a step bearing, or alternatively, for vertical swinging of the arms, the head 4 can be in the form of a socket of a ball-and-socket joint, the ball element being formed on the end of the arm 3. Pressure-gas is fed from a reservoir in the base 1 through insulating tubes in the insulators 2, to the extinguishing heads 6, and operates also vane or thrust pistons in the heads 4 or caps 7. The arrangement is stated to obviate the excessive stressing of the rotatable insulators, and robust driving and switching mechanism of the switch of Specification 483,996.

Title: Improvements in Radar Systems for the Detection and Location of Targets
IPC: G01S7/36
Filed: 1964-04-09
Abstract: 1,196,241. Radar. COMPAGNIE FRANCAISE THOMSON HOUSTON-HOTCHKISS BRANDT. 9 April, 1964 [9 April, 19631. No. 14802/64. Heading H4D. A target detecting and locating system for targets equipped with a jamming transmitter comprises an active radar system combined with a passive monitoring system. The passive monitoring system detects a target and determines its angular co-ordinates, this angular co-ordinate data being supplied to the active radar system as a control signal to cause its scanning mode to be modified and thereby facilitate the determination of the distance coordinate of the target by the active radar system. As shown in Fig. 2 the energy received by n horns 10 connected to passive receivers 11 is fed to a receiver 12, the latter deciding when a jamming target is present by the level of the signal. If a target is detected a logic circuit 13 controls switch 16, 17 and acts similarly on the active radar receiver 14 so as to modify its detection criterion as a function of scanning time. It also acts on the transmitter 15 to modify its scanning mode.

Title: Improvements relating to apparatus for assembling gas mask respirators
IPC: A62B9/04
Filed: 1938-05-18
Abstract: 514,910. Gas mask assembly apparatus. DOWNING, F. G. May 18, 1938, No. 14867. [Class 81 (ii)] Apparatus for assembling gas mask respirators consisting of a face-piece, a container fitted within an aperture therein and a rubber band encircling the margin of the aperture and the container, comprises a band stretching device consisting of a number of fingers 10 having their tips 16 arranged in a circle and movable radially by cam mechanism operated by a handle on treadle and means also operated by the handle or treadle for moving the container and face-piece previously assembled and placed within the fingers, together with the stretched band in a direction to strip the stretched band from the fingers and allow it to contract round the margin of the face-piece and around the container. The fingers are pivoted in brackets 22 by pins 18 engaging slots 20 and impelled inwardly by springs 26. The cam comprises the sleeve 32 sliding on the vertical tube 30 and by sliding on the inner sides of the fingers forces them outward. The tops of the fingers have shoulders for the correct location of the rubber band 28. Above an annular hole 14 in the top of the case 12 is an annular plate 38 having slots to accommodate the fingers 10 when fully extended but protuding inwardly intermediate thereof. This plate is supported by three rods 42 having lateral extensions 44 which engage with brackets 48 attached to the side of the sleeve 32 after the latter has stretched the band sufficiently to accommodate the container. As the plate begins to lift against the pressure of springs 46 between the lateral pins on the rods and the top of the casing, the sleeve lifts the container, which is placed within the fingers at the same rate, so that provided the face-piece has been correctly located on the container the rubber band is progressively stripped off the fingers by the inward projections of plate 38 to seal the face-piece on the container. For adaptation of the apparatus to different sizes of masks a distance piece attached to the upper end of the sleeve 32 by means of dowels may be provided. When not in use it can be attached to the side of the apparatus. The sleeve may be operated by hand or foot. A cross piece 62 in the sleeve and running in slots 64 in the tube 30 raises the sleeve and is operated by lever 50 running in other slots in the sleeve and tube. When the apparatus is foot operated the sleeve may be downwardly urged by a spring, and the connection between pedal and sleeve may be tripped automatically at the top of the travel and connection not be re-established until the sleeve has reached the bottom.

Title: New or improved automatic calendar
IPC: G04B19/24
Filed: 1933-05-25
Abstract: 418,526. Date indicators; clepsydras. TA'BOIS, P. L., 4, Holly Bush Hill, Hampstead, London. May 25, 1933, No. 15081. [Class 106 (iv).] A date-indicator of the clepsydra type comprises a vessel containing liquid, a second vessel having two permanently open means of communication with the first vessel, one means for causing a restricted flow of liquid from the first to the second vessel and the other for permitting an unrestricted flow between the vessels, and a scale of days or weeks associated with one of the vessels to indicate the date by the quantity of liquid in the vessel. In one construction water from a tank 10 passes up a wick 16, along a block 14 of porous material and down a wick 21 into a tube 11 connected to a tube 12. Adjacent the tubes 11, 12 are adjustably-mounted scales 34, 35 carrying day names and date figures. The rate of filling of the tubes is controlled by varying the length of porous material along which the water must travel, this being effected by turning a shaft 18 to which is secured an arm carrying the wick 16. The month names are displayed on a hand-set drum 64. In a first modification, the water passes into the tube 11 through a hole covered by a cloth or other sleeve which has pressure applied to it by screw means to adjust the rate of flow. In a second modification, the cloth sleeve slides along the shaft relatively to the hole so that the length of cloth through which the water must pass, and thus the rate of flow, is varied. In a third form, the rate of flow is altered by inserting a plug to a greater or less extent into the tube or, fourthly, by screwing a loose-fitting screw into and out of the end of the tube. In a fifth embodiment, thirty-one tubes are connected in series. The first tube is filled with liquid by the end of the end of the first day of the month, the second tube by the end of the second day, and so on.

Title: Improved motor control arrangements for type printing telegraph systems
IPC: H04L12/12
Filed: 1924-06-23
Abstract: 235,575. Kleinschmidt Electric Co., Inc., (Assignees of Kleinschmidt, E. E.). July 5, 1923, [Convention date]. Type-printing telegraphs.-In a printing-telegraph system, the motor driving the receiving apparatus is started into operation by an initial change from the normal condition of the line and operates thereafter independently of the transmission of signals or of the cessation of transmission. The arrangement is applicable to the printing-telegraph apparatus described in Specification 218,643. Fig. 1 shows two stations, each. provided with transmitting and receiving apparatus connected by a normally-closed line circuit. The receiving magnet 8, transmitting contact 461, motor control magnet 492, and a high resistance 493 at each station are connected in series in the line circuit, and the armature 491 of each magnet 492 is adapted, when released, to close the circuit of the motor 490 at the same station. The opening of either contact 461 by the starting of the corresponding transmitter, or the depression of a. starting key 495 at either station, breaks the circuit through both magnets 492 and starts both motors. The current passing through the magnets 492 upon the subsequent closing of the contact 461 is insufficient to pull back thearmatures 491. The motors are stopped. by the depression of a key 494 to short-circuit the resistance 493 at either station. Alternatively, the resistances 493 and keys 494 may be dispensed' with, and one station only be provided with a resistance 493<1>, Fig. 3, adapted to be shortcircuited to stop the motors by the closing of contacts 496<1>, 497<1> upon selection of an operating bar in the pointer at that station corresponding to a special combination of impulses sent to line. In a further modification, the contact 496<1> moves between two fixed contacts connected to a split battery, and its operation from the pointer asabove acts to send an increased battery current to line. News distributing systems.-Fig. 2 shows an arrangement for distributing news from a station A to stations B, C, &c. Each receiving magnet 8 is in a local circuit controlled by a polarized line relay 499. The transmitter contact 461 moves between fixed contacts connected as shown to a split battery 501, and magnets 492, being slow-acting, are not affected by the interruptions at the transmitter contacts. To start the motors a key 495 is depressed until the armatures 491 are released. To stop the motors the contact 496<1> is operated as above by the transmission of a special combination of impulses. Reference has been directed by the Comptroller to Specifications 9709/11 and 204,923.
