Title: Improvements in or relating to coaxial cable connectors
IPC: H01R9/05
Filed: 1965-09-28
Abstract: 1,109,914. Coaxial connectors. E. L. HUTCHINGS. 28 Sept., 1966 [28 Sept., 1965], No. 41248/65. Heading H2E. A coaxial connector has tubular contacts 1, 2 in the sides of which are formed resilient tongues 13, 5 having prongs 14, 15 which are forced into contact with the conductors 21, 20 of the cable 19 by axial movement of insulating sleeves 6, 9. The sleeves 6, 9 are screwed together, the resulting axial movement enabling conical section 10 and bush 7 to press on the tongues so that the prongs establish contact. The contact parts may be socket or terminal members and the connector may have a metal body in which the insulating bush 7 would be gripped by or moulded around support arms (16), (Fig. 2A, not shown). A separate bush 7 may have an internal groove and be held in position by pressure from tongue 13 engaging the groove. Prongs 15 may be modified (Figs. 5 and 6, not shown), if the cable has insulation of low mechanical strength.

Title: Photographic Shutter with an Electronic Timing Device
IPC: G03B9/64
Filed: 1966-09-15
Abstract: 1,150,373. Photographic shutters. PRONTOR - WERK ALFRED GAUTHIER G.m.b.H. Sept. 15, 1966 [Oct. 28, 1965], No.41274/66. Heading G2A. A photographic shutter has an electronic timing device which comprises an electromagnet 30 acting upon a detent to keep the or one of the pivoted blades of the shutter in its open position for the duration of the exposure. The shutter is shown in its closed, tensioned position. To make an exposure, a lever 17 is depressed, and its movement followed by a disc 32 thus moving a push rod 36 towards a locking lever 24. The rod 36 causes an armature 23 to make contact with the electromagnet Fig. 2 (not shown), which is currentless since a main switch S 1  is still open. Further rotation of the lever 17 closes switch S 1  thereby exciting the electromagnet and causing it to retain the armature (23 Fig. 3 not shown), while the disc 32 and rod 36 are returned to their initial positions Fig. 4 (not shown). Rotation of the lever 17 from the position shown to that of Fig. 4 also positions a drive lever 13 so that a shutter blade actuating lever 4 is only prevented from actuating the blades 5, 6 by a locking lever 18. Further rotation of the lever 17 releases the lever 4 to open the blades 5, 6 and allows a lever 44 to close a switch S 2 . When the shutter blades are clear of the opening, a protusion 6b strikes a tab 28a of a pawl 28 which tab forms the detent. Closing the switch S 2  causes a capacitor to start charging until it reaches the base potential of a transistor T 2 , when the circuit to the electromagnet is rendered currentless. The lever 24 and the pawl 28 are returned to the position shown by a spring 25, thus freeing the shutter blade 6 and hence the blade 5 to close under spring action. The lever 17 returns to its initial position, opening the switch S 1  as it does so.

Abstract: 1523115 Multi-frequency aerial system ANTENNA SPECIALISTS UK Ltd 19 Dec 1975 [24 Sept 1974] 41418/74 Heading H4A An aerial system for operation at two or more frequencies comprises a first conducting part tuned to a first frequency, and a second conducting part linked to the first by a length of transmission line. The length of the line is selected such as to provide a high impedance at the first frequency so that the second conducting part is then non-operative, and its characteristic impedance is chosen so that the line, together with the two parts, resonates at a desired second frequency. In the Fig. 2 embodiment, the first conducting part is a centre-fed tubular dipole 12, 13 within a glass fibre tube 10 and having a downlead 15. Bayonet fittings 4a, 3b and 5a, 4b join this assembly mechanically to a lower elongate support (not shown) and to an upper aerial element so that the whole system is of vertical whip antenna form. The bayonet fittings also constitute the second conducting part and are linked to dipole elements 12,13 by short-circuited (or open-circuited) lengths of transmission line 16, 17 so that dipole 12, 13 is resonant at one frequency, whereas the dipole plus bayonet fittings plus transmission lines together resonate at a second frequency. The upper aerial element includes a loading coil 20 and is tuned to a third frequency. The transmission lines 16, 17 may be of coaxial form as shown, or of flexible coplanar microstrip form. In the latter form, the widths and spacings of the microstrip conductors are chosen to provide a suitable characteristic impedance. Aerial dimensions and operating frequencies are specified.

Title: Improved elastomeric yarns
Inventor: MOHAJER ALI AKBAR
IPC: D06M15/59
Filed: 1965-10-11
Abstract: An N-alkylated copolymide elastomer suitable for use in the manufacture of elastomeric yarns, is produced by the reaction of N,N1diisobutyl hexamethylene diamine, sebacic acid, 11-amino undecanoic acid and caprolactam.ALSO:Synthetic elastomeric yarns having reduced surface friction are produced by coating at least one uncoated synthetic elastomeric filament with a synthetic fibre forming non-elastomeric polymer. The coating may be effected by successively treating the filament or filaments with the polymer forming ingredients dissolved in substantially immiscible solvents. Polyamides may be formed from a diacid chloride and a diamine in the presence of an acid acceptor, e.g. sodium carbonate, polysulphonamides from a disulphonyl chloride and a diamine, polyureas from a diisocyanate and a diamine and polyester from a diacid chloride and a dihydroxy benzene.  One of the solvents is preferably water and the other solvent may be methylene chloride carbon tetrachloride or chloroform, the first solvent applied preferable being a swelling agent for the elastomeric filaments treated as well as a solvent for the polymer forming ingredient.  The coating is preferably applied to the filaments in the drawn state. It may be applied to the wet-spun, dry-spun or melt-spun filaments after spinning prior to winding on the package.  If the filaments are drawn after coating they crimp spontaneously in the relaxed condition.  The treating solutions may be applied by passing the filaments in contact with the solution at one end of a capillary tube preferably having channeled or formed therein a grove along which the filaments are passed, the other end communicating with a constant head reservoir of the solution.  Spinning finish applied to the filaments is removed prior to the coating.  Filaments made from polymers formed by the reaction of a polyester or copolyester, a diol or diamine and an aromatic or aliphatic diisocyanate, or from an N-alkylated copolyamide elastomer formed by the reaction of N, N\sv-diisobutyl hexamethylene diamine, sebacic acid, 11-amino undecanoic acid and caprolactam may be treated.  The treated yarns may be used in the manufacture of surgical hose.

Abstract: 444,747. Spray carburetters. GES. FUR KREDITPRUFUNG GES., 26, Westfõlische Strasse, Halensee, Berlin. June 25, 1934, Nos. 18727 and 18728. Convention dates, June 24, 1933. [Class 7 (iii)] The fuel supply is controlled partly by a member coupled to the throttle valve so as to regulate the supply in dependence on the throttle opening and partly by a piston working in a chamber subject to the suction in an airconduit which is not controlled by the throttle valve and through which air, for entraining and mixing with the fuel when the engine is running light, is drawn into the carburetter, the suction in the air conduit when the engine is running light displacing the piston to open a fuel valve for slow running. The nozzle fitting shown in Fig. 3 is placed across the mixing chamber 1, Fig. 1, on the line A ... B. When the air valve 2 is closed, engine suction operates through a passage 12 to draw to the right a piston 8 formed with a coned surface 15 which engages a pin 19, projecting downwards from the casing 26 of the nozzle fitting, to open slightly a fuel valve 21, the air necessary for idling being drawn through a passage 13. The valve 21 is mounted in a nozzle member 18 having a reduced lower end, the hollow centre 29 of which communicates by ports 28, 30 with chambers 27, 27<1> formed by the outer casing 26 and separated by a perforated flange 311 on the end of the nozzle member. Above the valve 21, a chamber or reservoir 34 is provided beneath a calibrated nozzle 33. For idling, the movement of the piston 8 is limited by a flange 17 thereon engaging a pin 7 on a plunger 5 slidable in the housing of the piston. An arm 3 on the shaft of the air valve 2 displaces the plunger as the air valve is opened to move the piston further so that the cone 15 opens the fuel valve 21 correspondingly. Air from the passage 13 then passes through the ports 30 to mix with the fuel, the emulsion passing out through the ports 28, chamber 27, and ports 25 in the casing 26. The chamber 34 provides fuel for acceleration and if the air throttle is opened while the engine is at rest, the chamber 29 fills with fuel to facilitate starting. In a modification, Fig. 6, fuel for idling flows from the main nozzle 15 through a nozzle 7 and passage 8 to a suction operated valve 10 communicating by a passage 14 with the mixing chamber 1. Air is supplied through an adjustable passage 13. During normal running, emulsifying air flows past a screw 28 to the housing of the plunger corresponding to the plunger 5, Fig. 1, and thence through passages 27, in the closed lower end of the nozzle casing 19, and ports 25, 26 to discharge apertures 19<1>.
