Title: Improvements in apparatus for testing gas mixtures
IPC: G01N27/18
Filed: 1923-11-14
Abstract: 212,852. Marks, E. C. R., (Siemens & Halske Akt.-Ges.). Nov. 14, 1923. Gas analysis.-Relates to apparatus for testing flue gases &c. in which the changes of resistance in an electrically-heated conductor, due to variations in the cooling effect arising from changes in composition in the gas, are utilized to give an indication of such changes in composition. The electrically-heated conductor 11, 12 constituting the two arms of a Wheatstone's bridge, is placed in passages 7, 8 in one block of metal, and the other pair of arms 9, 10 are placed in a standard gas and in passages 5, 6 in another block of metal. The gas to be tested is passed through a passage 15 bored through the firstmentioned block and communicating with the passages 7, 8, through small openings 14 so that the flow of gas along the wires 11, 12, is considerably less than that along the passage 15. Specifications 124,453 and 127,656 are referred to.

Abstract: 1,064,874. Converting oscillating motion into rotary motion; cams. OMEGA LOUIS BRANDT & FRERE S.A. July 13, 1964 [July 16, 1963], No. 28884/64. Headings F2K and F2Q. [Also in Division G3] In a timepiece of the kind having an electrically maintained balance 1, a motiontransmitting mechanism steps on a toothed wheel 12 driving the time train. A lever 7 is pivoted at a forked end 8, 9 which carries a spring pawl 13 engaging the wheel. The other end 4 of the lever has a circular opening, with a gap 6, surrounding the balance arbor. The included angle of the opening up to the ends of the gap, exceeds 180 degrees, the arbor being slightly eccentric to the opening. The balance carries a crescent-shaped driving shoe 3 which in the neutral rest position is opposite the gap and clear of the end 4 so that the balance can readily start. At the normal amplitude of swing, e.g. 200 degrees, the shoe passes through the gap 6 but without engaging the outer surface of end 4. If this amplitude is exceeded, the shoe by engaging the outer surface banks the inner surface against a sleeve on the balance arbor. A fixed detent pawl 14 carried by a springy slotted bridge 17, is adjustable by two screws 20, 22 which vary the slot.

The pump comprises a cylinder m, a tubular piston-rod p<1> carrying an annular piston in the form of a cup leather p, and a concentric discharge tube o. A non-return valve o<1> is arranged at the upper end of the discharge tube, and a second non-return valve o<2> at its lower end. A sleeve p<6> carried by the pump handle p<7> carries a pin p<5> adapted for locking engagement with a catch m<4> on the cylinder head m<1>, and in this position the sleeve compresses packing material p<8>. In a modification, the valve r is replaced by a frangible sealing disc, and the plunger t carries a piercing needle. In another modification, the control casing is arranged at the upper end of the extinguisher, and carries the discharge nozzle.

Abstract: 449,736. Fishing. SAELEN, E., 30, Skivebakken, Bergen, Norway. Oct. 21, 1935, No. 28972. [Class 48] [See also Group XI] The lamp socket 5 of an electrically illuminated fish bait is filled with a plastic waterresistant mass 6 and the lamp is unenclosed. The contact between the lamp and the battery is made by a pin 7. The bait is secured to the line by a ring 23 on the end of a pin 18. The conical end 20 of the pin 18 normally engages a spring-pressed wire 17 and holds it out of contact with the battery 11. When the bait is suspended, however, its weight releases the wire 17 and the circuit is completed. A flicker effect is obtained by jerking the line. The bait is made watertight by insulating material 10, 12. The lamp bulb is protected by pins 27.

Inventor: PAUL ADOLF
IPC: B66C13/18
Filed: 1960-08-23
Abstract: 899,495. Folding jib cranes on vehicles. STEINBOCK G.m.b.H. Aug. 23, 1960, No. 29175/60. Class 78 (4). A vehicle mounted crane used for loading has a slewable column 28, Fig. 1, which can be swung hydraulically in a vertical plane from an inoperative position shown to a vertical working position. As described, a jib 34, pivoted to the column 28 at 36, is supported in the inoperative position parallel to the rear wall of the driver's cab and symetrically with respect to the longitudinal axis of the vehicle. Stops 32, 33 maintain the column 28 in the working and inoperative positions respectively. The jib, which has a telescopic portion 44, held in extended position by a lock 48, is luffed by an hydraulic ram 38, and the crane is slewed by a rack and pinion. A piston 58, Fig. 7, moved hydraulically within a cylinder 50 which rotatably supports the column on bearings 52, 54, tilts the column through a rod 68 and shackles 84 connected to plates 86 of the column 28. Springs 62, 64 urge the piston upwardly, thus moving the column to the inoperative position. Alternatively a double-acting ram may be housed within the cylinder 50. Fig. 5 shows an embodiment in which a cable 92 is secured to the pivot pin 30 and passes over a first roller 90, a roller 94, second rollers 90, 94 and subsequently rollers 96, 98, 100. Since rollers 98, 96 are attached respectively to inner and outer telescopic parts of the jib, as section 44 is moved out the cable is paid out by an amount equal to the distance between rollers 96 and 98, the cable being shortened by extending ram 38. Alternatively a cable drum may be provided at the top of the column 28, the cable passing over two rollers mounted on the jib. The two hydraulic rams, 58, 38, are so coupled that the column is first raised to the working position after which the jib is luffed.

[Class 36.] An insulator is protected from sun and rain by a shield which is supported above the insulator by means which offer high resistance to the conduction of heat from the shield to the insulator and which provide a free air space across the top of the insulator body between the shield and the top of the insulator. The supporting means may be carried by the top portion of the insulator, by the conductor supported by the insulator, or by a clip which secures the conductor to the insulator. The shield may be of galvanized iron, papier machÚ or asbestos composition, and additional shields may be disposed intermediate of the ends of the insulator. In the construction shown, a pin-type insulator 1 supporting a conductor 4 is provided with a domed shield 2 which is attached to. the insulator by a clip 3 having depending limbs which are formed with fingers 11 to grip the head 12 of the insulator above the tie-wire groove 9. To prevent the conduction of heat from the shield to the insulator, the clip 3 and the shield 2 contact with each other only at their central portions, where they are riveted together.
