Title: Improvements in vaporising and charge-mixing devices for internal combustion engines
IPC: F02M29/06
Filed: 1925-11-03
Abstract: 256,829. Fairlie, T. W. Nov. 3, 1925. Induction pipes, fittings for.-A charge-mixing device comprises a series of spaced slats arranged helically and extending transversely across the induction pipe. The device may be formed by threading a number of rectangular strips of metal 8 on a central rod 9, the strips being spaced apart and turned about the rod so as to assume a helical formation. Stiffening wires 10 may be secured to the tips of the strips. The device may be fixed in a gauze cylinder 11 secured in position in a section 13 of the induction pipe by a flange 12, an annular space 14 being left between the cylinder and the induction pipe. In a modification, the helical member is made from a strip of metal having two parallel edges from each of which a plurality of slots are cut, the strip being twisted about an axis at right-angles to the slots into helical form.

Title: Improvements relating to fuel supply interrupter circuits
Inventor: BROOKS WILLIAM HENRY
IPC: H03K3/284
Filed: 1962-07-19
Abstract: 972,435. Change-speed control. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. June 19, 1963 [July 19, 1962], No. 2700/62. Heading F2D. [Also in Division H3] To interrupt for a predetermined time the supply of fuel to an engine driving a vehicle transmission, an oil-operated and driver controlled switch S is opened to render conducting a transistor T1 and thus feed a current pulse through a condenser C to the base of a transistor T2, which accordingly becomes non-conducting and in turn renders a transistor T3 and a power transistor T4 conducting, the latter energizing a solenoid L and causing a fuel interrupter I to become operative. As soon as the transistor T1 conducts, charging of the condenser C is begun through a resistor R2. After a period determined from the time constant of the circuit C, R2, the condenser is fully charged and is thus able so to bias the transistor T2 that it once more conducts, rendering the transistors T3, T4 non-conducting and re-opening the fuel interrupter I. Re-opening of the fuel interrupter I is not affected by keeping the switch S open longer than the predetermined time, since the condenser C is then merely maintained charged.

Title: Contact lens edging tool
IPC: B24B9/14
Filed: 1961-07-31
Abstract: 908,872. Grinding lenses. PLASTIC CONTACT LENS CO. July 31, 1961 [Aug. 8, 1960], No. 27744/61. Class 60. [Also in Group XXII] A tool for edging contact lenses comprises at least three abrading elements so spaced as to permit a lens to contact all three elements and means for rotating the tool and/or the abrading elements relatively to the lens or the lens relatively to the tool and/or the abrasive elements. These elements 74a, 74b, 74c, Fig. 5, are removably but drivingly mounted on vertical shafts 68 each having a pinion 82 at its lower end in mesh with a toothed ring 84 fixedly mounted in a housing 38. A cover 46, rotatable by a motor-driven shaft 48 relative to the housing, carries the abrading elements 74 and their shafts 68 so that rotation of the cover causes the tool head and the abrading element to rotate. The abrading faces of these elements are each at a slightly different inclination to their respective rotational axes, thus grinding successively three separate zones towards the edge of the lens L<SP>2</SP>, Fig. 6, which may be mounted on a vacuum-type holder 90 and gyrated manually during grinding or polishing, the three zones being merged by using a covering of yielding material 78 on the elements 74. The latter may be rotated without circumferential motion relative to the lens by holding the cover 46 and rotating the housing 38 manually; a stop 86 may be used to prevent rotation of the housing when the cover is motordriven. The anterior edge portion of a lens L<SP>6</SP> may be ground by the arrangement shown in Fig. 11 in which the shafts 68 are journalled in a carrier 46, the pinions 108 planetating about a fixed sun-wheel 106. One of the abrading elements h has a flat working face to shape the rim of the lens. For polishing, a padded covering of the elements 74 is used with an applied polishing composition.

Abstract: 477,064. Hardening rails &c. THORNTON, A. A. (Bochumer Verein f³r Gusstahlfabrikation Akt.-Ges.) Oct. 13, 1936, No. 27756. [Class 72] In a device for hardening rail heads or similar longitudinal surfaces, a plurality of nozzles are arranged in staggered relation on both sides of the rail head &c., and also transversely thereto so that the jets of cooling medium are directed in the same or substantially the same plane as the surface of the head &c., both heads and nozzles being relatively movable in the longitudinal direction of the rail &c. The nozzles 1, Fig. 1, are arranged as shown and the rail is moved past the nozzle. To prevent the quenching medium from contacting with other parts of the rail than the head, protective plates 2 with sharpened edges 3 which press resiliently against the rail below the head are provided. In another form, Fig. 2, the rail 4 is fed with its head downwards by rollers 5 mounted in a frame 13 past a quenching device 12 consisting of staggered slotted nozzles 6, which are arranged in pairs connected with a common feed pipe 7. Each pair of nozzles is carried by a lever 8 which are connected to a pin 9 carrying a roller 10, and is provided with a projecting free end having an aperture in which the pin 9 carrying the next pair of nozzles is mounted. After quenching, the rail is fed forward by rollers 15 resiliently and movably mounted in a frame 14.

Filed: 1937-10-13
Abstract: 504,182. Keys and looks. ALBERTZ, R. Oct. 13, 1937, No. 27857. [Class 44] A'key for a revolving-barrel look has six, three or two cams so that it may operate a corresponding number of locks. Six locks having barrels slotted as in Fig. 2, could be operated by a key having six cams, the key being inserted with a different cam uppermost for each lock. When supplied with a new lock the key has only one cam cut, leaving the remainder to be adapted to other locks. Normal locks may be modified to receive the multiple key by exchanging the barrel for one having a multiple slot. The multiple key may be used with locks having two or more pin sets converging to the centre of the key. In order to still further increase the number of locks operable by one key, the key may consist of a part having cams at each end fitting into a handle portion as shown in Fig. 7. Reference has been directed by the Comptroller to Specifications U171/10, 1140/15, 130,003, and 222,820, [all in Class 44].

To adjust the separation of the pulley flanges, a locking-bolt 19 at the rear of each of the outermost flanges 16 is unscrewed and released from the castellations on an associated ring 17 forcefitted upon the hub of the central flange 14. The outermost pulley flanges 16 are turned and, by means of the part-threaded pins 18, turn the adjacent flanges 15, the flanges thus screwing along the threads 14a, 14b. The released locking-bolts 19 are then re-engaged with the castellations upon the rings 17. The end faces of the rings 17 bear indicating-marks corresponding to the separation of the pulley flanges and the ratio of the drive. The central flange 14 and its hub are secured upon the shaft 12 by a key 13 and an end bolt 21. The shaft 12 is the armature shaft of an electric motor, Figs. 1, 2 (not shown), mounted upon a support-plate pivoted about one bar integral with the frame of a loom by adjustment of nuts along a bolt pivoted about a second, parallel, bar, to adjust the belt tension.
