Abstract: 1437770 Ignition systems LUMENITION Ltd 31 May 1974 24307/74 Heading F1B A transistorized ignition system disclosed in Specification 1330453, in which the voltage across the emitter-base junction of every transistor TR1, TR2 and TR3 is clamped by diodes D1, D2 and D3 connected thereacross to prevent the reverse voltage across the junctions from exceeding the transistor breakdown value. The power stage P consists of a Darlington pair TR4, TR5 or a single transistor, and is protected by a diode D5 and a Zener diode Z2 connected in parallel with a capacitor C1 across the base of transistor TR4 and the collector of TR5. The voltage supply to a gallium arsenide lamp GA, a photo-transistor PH and the transistors TR1, TR2 is obtained across a Zener diode Z1 which stabilizes the voltage at 7.5 volts, and is connected in series with a resistor R1 across the battery voltage at 12 volts. Two, three or four transistors may be provided in the trigger circuit.

Abstract: 1450295 Seals; pistons; crossheads PUMPENFABRIK LRACH 4 June 1974 [7 June 1973] 24679/74 Headings F2B and F2T In the cylinder 11 of a plunger piston 12, instead of a rigid circumferential support for the sealing bush 23, an endwise support allows radial and angular displacement of the bush. Thus, a plane interface 30, with a ring 26, allows the bush 23 to move radially, while a spherical interface 31 allows both 23 and 26 to move angularly about the centre of curvature M of this interface. The floating bush is thus centred by fluid pressures acting in the sealing gap 24 and external space 36 and the axial pressure of compression spring 37. 0-rings 32 and 33 may be omitted if narrower interfaces (34, 35, Fig. 2, not shown) are employed.

Abstract: 856,797. X-ray apparatus. SIEMENSREINIGER-WERKE A. G. July 22,1959 [July 30, 1958], No. 25167/59. Class 98(1) An X-ray apparatus has an image intensifier 6 and a television camera 5 arranged with their optical axes mutually perpendicular, the image being reflected from the intensifier into the camera by a mirror, the X-ray tube 10 itself being carried by an arm 9 so angled that a patient may be disposed between X-ray tube and intensifier. The components are carried by a slide 4 which is movable vertically, and also rotatably, on a column 3. The television camera 5 is fixed to the slide 4 so that its axis is always horizontal. The intensifier 6 is mounted at right-angles to the camera, and can rotate about the optical axis of the latter. The intensifier is secured to a counterbalancing support 7. Mounted on a pin 8 coaxial with the camera axis is an arm 9 carrying the X-ray tube 10. The arm 9 is angled as shown in Fig. 3 so that it is clear of the patient under examination, who lies on a couch 13. The support 7 is coupled to the arm 9 by a rod 12, so that they rotate together, with the X-ray tube and intensifier remaining in alignment in all positions. In the position of Fig. 3, the X-ray beam traverses horizontally. By rotating the whole unit 10, 9, 12, 7, 6 through 90 degrees about the pin 8, then lowering the whole unit by moving slide 4 down the column and then rotating the slide, the position of Fig. 4 (not shown) is reached, in which the beam traverses vertically. The provision of the television camera enables the X-ray image to be displayed at any desired position in the examination room, or even outside it.

Abstract: Trialkyl tin mono-alkoxides, wherein each of the alkyl groups contain not less than 4 carbon atoms and the alkoxy group contains from 1 to 8 carbon atoms, which are contaminated with dialkyl tin dialkoxides are purified by a washing treatment with water or aqueous alkali. The trialkyl tin mono-alkoxides may be prepared by reacting the corresponding trialkyl tin halide prepared by a Grignard reaction with an alkali metal alkoxide.  The treatment may be carried out at normal temperatures.  The preferred alkali is sodium hydroxide but any hydroxide, carbonate or bicarbonate of the alkali metals, alkaline earth metals or ammonia may be used. In the examples the following compounds are purified:-tri-n-butyl tin mono-n-butoxide and tri-n-octyl tin mono-methoxide.  Tri - n - butyl tin mono - n - butoxide is prepared from n-butyl magnesium bromide and stannic bromide and adding sodium-n-butoxide to the reaction product.  Some tetra-n-butyl tin is also formed.  Tri - n - octyl tinmono - methoxide is obtained from the reaction of tri-n-octyl tin chloride and methanol.  Specifications 590,734 and 692,554 are referred to.

Abstract: 280,019. Ragan, F. H. Oct. 14, 1926. Band; blocks and the like acting on drums; force-transmitting mechanism; compensating for wear. - Actuating mechanism for brakes on steering wheels of vehicles comprises a member substantially parallel with and extending along the axle and having a portion which is fixed relatively to the member in the direction of its length and is adapted to exert a pushing action on the brake shoes when the member is moved longitudinally of the axle. In the arrangement shown in Figs. 1 and 3 the actuating member 26 carries an adjustable ball-shaped portion 25 which engages inclined semi-cylindrical recesses 22, 23 in wear plates 20, 21 secured on the brake shoes 10, 11, the ball 25 being normally in line with the steering pivot. The anchored ends of the brake shoes abut against pins 12, 13, Figs, 3 and 6, slotted to engage a tapered plate 14 adjustably mounted in the brake plate 19. The shoes are held in the off position by a coil spring 28 and by a flat spring 29 carried by the brake plate 19. The member 26, which is supported at its outer end by its engagement with the brake shoes, is connected at its inner end to one arm of a three armed lever 81 the other arms of which are connected to the actuating member 26<1> of the brake on the other steering wheel and to a rod 84 which may be connected to a brake pedal. The lever 81 is mounted on a bracket 82 on the axle and by means of a pin-and-slot connection so that the pull on the members 26, 26' is equalized. In the modified equalizing arrangement shown in Fig. 11, the rods 26, 26<1> are connected to levers 96, 96<1> pivoted to an axle bracket 97 and having pin-and-slot, connections 100, 100<1> with a bar 101 connected to the operating rod 102. In the modification shown in Fig. 9, the actuating member 60 carries an adjustable socket-member 61 forked at its outer end to carry rollers 67 which engage recesses in wear plates 70, 71 on the brake shoes 40, 41. The anchored ends of the shoes abut against cams or eccentrics carried by a shaft which may be rotated in the brake plate for adjusting the shoes. In a further modification, the actuating member carries a pivoted wedge which engages between rollers on the ends of the brake shoes. In the arrangement shown in Figs. 12 and 13 for anchoring a modified form of brake shoes, plates 107, 107<1>, secured respectively between the ends 105, 105<1> of the shoes and plates 106, 106<1> attached thereto, have bevelled ends which engage in slots 109, 109' in discs 110, 110<1> carried on a right-and-left-hand screw-threaded bolt 120 mounted in the brake plate 125. The position of the shoes may also be adjusted by screws 111 mounted in a bracket 112 on the brake plate and having reduced portions engaged in slots in the plates 106, 106'.
