Patent GB-671841-A (GB)
Abstract: 671,841. Workmen's time recorders. KRAUSE, A. C., and NATIONAL TIME RECORDER, Ltd. July 28, 1950 [Aug. 22, 1949], No. 21773/49. Class 106 (iv). A workmen's timerecorder has clock-operated means for controlling the position of the fulcrum of a card-stop lever which is engaged by one arm of a bell-crank lever whose other arm pivotally supports a swinging lever normally retained in a position against a stop where means thereon may close an electric switch controlling an electromagnet adapted to operate a printing hammer to press a card against printing means and to actuate a trip lever which causes the swinging lever to disengage from the switch operating member and allow the switch to open to de-energize the electromagnet. A record card 2 is inserted in a shoot 16 to an extent determined by the position of the pivot 18 of a card stop lever 17 which is pivoted on an arm 19 rigid with a shaft 20 which controls the position of the pivot 18 according, e.g. to the day of the week preferably through a pin 23 engaging a timedriven cam 22 or by means suitably driving the shaft 20. The card 2 then rocks the lever 17 so that an arcuate surface 24 at its other end rocks a bell-crank lever 25, 27, weighted at 44 and pivoted at 26 to draw aside a latch member 29, pivoted to one projection of the arm 27 and weighted at 30 to rest on another projection 31. The member 29 engages a pin 34 to rock a lever 35 against a spring 37 and causes a mercury switch 38 to close the circuit of an electromagnet 5, whose armature 6 then rocks a shaft 8 against a spring 42 and through a lever system 7, 9, 10 and roller 13 causes a hammer 4 to strike the card 2 against a time type wheel 1 with an ink ribbon 3 interposed. At the same time the hammer shaft 15 rocks against a spring 14 and an arm 41 thereon strikes a pin 39 on the latch member 29 and releases the pin 34 so that the spring 37 rocks the lever 35 causing the mercury switch 38 to open the circuit which cannot be closed again until the card is withdrawn to allow the end 24 of the lever 17 to fall followed by the arm 25 which will then cause the latch member 29 to move across to re-engage the pin 34. Specification 21554/07, [Class 106], is referred to.

Abstract: 800,227. Sparking plugs. BENDIX AVIATION CORPORATION. Sept. 5 1956 [Sept. 29, 1955], No. 27214/56. Class 7(4) [Also in Group XL(a)] Sparking between the electrodes 11, 14 or 31 and 34 takes place through a narrow annular passage 16 or 36 between two insulating members. In Fig. 1 the outer surface of the passage 16 is preferably made semiconductive or highly resistant to the conduction of electrical energy in any known manner such as by coating the same with carbon, graphite, finely divided metallic particles or the like. If a sufficiently high voltage is available it is not necessary that the bridging surface be semi-conductive. The radial width of the passage 16 may be uniform or tapered and the inner surface of the passage may be highly resistant or semi-conductive. The electrodes 11, 12 or the active margin thereof may be made of a different metal from the shell 10 and secured in or to the shell such as by brazing, silver soldering or the like. The ring 20 is either press fitted, brazed or screwed into the shell 10. In Fig. 3 the outer surface of the passage 36 is preferably semi-conductive and the inner surface of this passage may also be semi-conductive. The walls of the annular passage may diverge slightly from each other or one from the other. If desired, the central insulating means 17 or 35 may be somewhat shorter or extended into and even through the centre of the ground electrode. The constricted annular passages 16, 36 may have radial widths of the order of 0.003 to 0.008 in. The width may be of the order of 0.050 in. or less. The invention is suitable for spark plugs in jet and gas turbine engines or for ignition devices for oil burners and reciprocating engines.

Title: Method of and apparatus for extracting amine compounds from air samples
IPC: B01D53/54
Filed: 1980-07-25
Abstract: Apparatus for removing amine compounds from an air sample containing oxides of nitrogen without loss due to formation of nitrosamine artefacts comprises a cartridge (20) having an interior separation zone (A) between a first port (22) and a second port (24) at opposite ends of the cartridge.

Filed: 1981-04-07
Abstract: In a method of tightening the spokes of a wheel having the spokes connected to the wheel hub (25) and each provided with a loosely threaded spoke nipple at the outer side of the wheel rim (24), the hub is first clamped against the upper end (5) of a support column (2) by downwardly moved piston (6), with the rim (24) locating against adjustable pins (13) carried by plates (9) on the column (2).
