Title: Remote-control electric circuit-breaker
IPC: H01H71/70
Filed: 1947-03-31
Abstract: 624,041. Automatic circuit-breakers; airblast switches; snap - actiun switches. FORGES ET ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT. March 31, 1947, No. 8650. Convention date, April 19, 1946. [Class 38(v)] A circuit-breaker, with two breaks in series per pole, closed by an electric motor against an opening spring, and held closed by an electro-magnet acting on a lever system, comprises two fixed contacts 1, and associated magnetic blow-out coils 20 mounted side by side in separate arc-chutes and co-operating with a pair of contacts 2 carried by an arm 4 pivoted at 5 to an arm 6 pivoted at 7. A compression spring 16 pivoted at 17 to the other end of the contact arm 4 provides the contact-pressure and opening force. The circuit-breaker is held closed by an energized electromagnet 15 having its armature 13 pivoted at 14 and connected by a link 12 to the pivot 5. When the electromagnet 15 is de-energized, the spring 16 first causes the contact arm 4 to rock about the pivot 5, Fig. 2, (not shown), after which the arms 4, 6 are forced down together to open the contacts and compress the bellows 9 which send a blast of air through the nozzles 11 across the break, Fig. 3. To close the circuitbreaker, motor 19' driving a crank 19 with lost motion through suitable gearing, raises a link 18 engaging the pivot 17 in a slot in its lower end, to first rock the arm 4 further about its pivot 5, until it engages a stop 29 on the arm 6 after which the arms 4, 6 are raised together, pulling the bellows 9 with them by means of hook 8. When the crank 19 reaches "top-deadcentre," the motor-armature is short-circuited by auxiliary contacts and the arm 6 is held up by the electromagnet 15 and associated linkage. The lost motion A between the crank and motor, Fig. 5, allows the spring 16 to rotate the contact arm 4 about its pivot 5 and rapidly close the contacts. The circuit-breaker chassis is supported on insulators inside an earthed casing, Fig. 6, (not shown).

Title: Photographic roll film
IPC: G03C1/765
Filed: 1965-03-02
Abstract: 1,086,148. Photographic role films. AGFA A. G. March 2, 1965 [March 4, 1964], No.8971/65. Heading G2A. To prevent distortion of a photographic roll film when it is inserted into a spool-less cartridge and wound between a spring and a small cylindrical roller, the leading end of the film has its mass reduced symmetrically of the longitudinal central axis of the film, so as to render the leading end more flexible. The reduction in mass may be obtained by cutting out one or more portions of the film, e. g. one cut out portion being triangular; by providing the leading end with a recess; or by progressively reducing the film thickness towards its leading edge. The other end of the film may similarly have its mass reduced also.

Abstract: 1,139,079. Sea cells. L'ELECTRONIQUE APPLIQUEE. 1 March, 1966 [1 March, 1965; 12 Dec., 1965], No. 9005/66. Heading H1B. In a sea water battery comprising at least one stack of cells having a plurality of electrodes separated by water-saturable insulating spacers which are exposed along at least one edge and a water-tight cover which seal the exposed edges of the spacers, means are provided for allowing the filling of the spacers through the exposed edges and the subsequent sealing of the edges by the cover when the spacers are full. In the battery shown, each stack comprises a plurality of cells encapsulated in a thermosetting resin except for one edge 28 of the spacers. Covers 31 carried by the armatures 32 of electromagnets 35 are urged into sealing engagement with the edges 28 of the spacers by springs 33. On immersion, the electromagnets are energized by an auxiliary sea cell 42, attracting their armatures 32 and exposing the spacers. When the battery 30 is full and the auxiliary battery exhausted, the electromagnets of the various stacks are energized in sequence from battery 30 and rotary distributer 47. The stacks are opened in sequence, thus preventing interstack current leakage. The electromagnets may be replaced by an electric timer acting on the covers via cams, an auxiliary battery being provided to initiate the opening sequence (Figs. 9 and 10, not shown). In another embodiment (Figs. 11-14, not shown) each stack of cells has its spacers exposed at opposed edges and covers are provided for each edge. The covers are held open against spring action until the stacks are filled on immersion. Expelled electrolyte and gas acts on spring biasedpistons which permit the covers to close. Evolved gas escapes by raising the covers during operation.

Patent GB-1096857-A (GB)
Title: Automatic loom
IPC: D03D43/00
Filed: 1965-03-05
Abstract: Weft replenishment is effected by rewinding the bobbins without removing them from the shuttles.  When a shuttle in operation in the bottom cell of a rotary shuttle box (position A, Fig. 5) becomes depleted, the box turns to move a full shuttle from position D to position A and to move the depleted shuttle to position B where the remaining weft is stripped off its bobbin as shown in Fig. 6.  A wire hook 74 descends through a hole 108 in the shuttle box to pick up the weft and draw it out of the shuttle between rotating nip rollers 76, 77 housed in a suction duct 75 which disposes of the weft remnant. When the next shuttle is depleted, the shuttle box turns again and takes the emptied shuttle to position C, Fig. 5, at which the bobbin is rewound.  As the shuttle approaches position C, a peg 49 on the shuttle box encounters weft yarn extending from a supply cone 66 through a traversable thread guide 48 to a clamp 39 at position D; the peg deflects the yarn across the top of the shuttle as shown.  An arm 46 pushes the yarn into engagement with teeth 13 on the bobbin 11, whereby on rotation of the bobbin the teeth trap the yarn so that it winds on to the bobbin, the piece of yarn passing round the peg 49 breaking at this stage; the bobbin is driven by a friction wheel 54 lowered into contact with a wheel 12 on the bobbin.  When the bobbin is full, the guide 48 has reached the position 48\sv near the tip of the bobbin.  An arm 38 draws a loop of the yarn and deposits it in the clamp 39 at position C; the clamp holds it until the shuttle becomes active on moving to position A.
