Abstract: 620,085. Turning-gear. SOC. DES MOTEURS THERMIQUES. Jan. 3, 1947, No. 251. Convention date, Aug. 31, 1944. [Class 7 (v)] In a starting and driving mechanism for electric generators and other machines driven by an internalcombustion engine, an energy storing fly wheel, which runs freely and in a continuous manner on one end of a shaft of the driven machine or on one end of the shaft of the internal combustion engine; is adapted to be automatically connected by means of an electrically-controlled clutch to the engine, which is itself coupled to the driven machine, these two machines being normally stationary. A flywheel 5, driven by an electric motor 9 through a belt and pulley drive, rotates freely on a shaft 4 which connects an internal combustion engine 2 with an electric generator 1. Upon failure of an electric supply, the motor 9 stops and an electromagnetic clutch 7, 8 couples the flywheel with the shaft 4, the energy in the flywheel being available to start the engine 2 thereby enabling the generator 1 to feed into the dead supply mains. In a modification, the generator is connected to the engine through a centrifugal coupling. The centrifugal coupling may be replaced by an electrically or mechanically controlled clutch, the flywheel may be driven from the electric motor by an electromagnetic connection, and all the automatic operations should be controlled by electrical contact means which may include delay mechanisms operative upon starting and stopping of the generator. It is also stated that the generator may be replaced by a transmission, pump, or compressor.

Abstract: 401,367. Mechanical race games. KENNEDY, P. G., 8, Throgmorton Street, London. May 12, 1932, No. 471/33. Divided on 401,346. [Class 132 (ii).] A miniature selfpropelled vehicle for use in a race game comprises a front axle unit adapted to engage and co - operate with a guide by means of a bi-lateral connection which holds the vehicle to its course and permits the rear of the vehicle to move towards or away from the guide. As shown in Fig. 1 a miniature automobile comprises a body 1, a rear axle and wheel unit 2, an electric driving motor 3, and a front axle unit 4. The body comprises an upper part 5 of sheet metal or moulded composition, as shown, with moulded-in and tapped inserts 7 for holding screws 8 and a lower part 6 carrying the motor 3 and the front axle unit 4. Clearance apertures 11 disposed half in the upper body part 5 and half in the lower part 6 allow free rotation of the rear axle. A pin 13 in the front axle structure passes through a hole 14 in a forward extension 15 of the lower body part 6 with clearance, the permissible relative movement between the front axle and the body part 6 being controlled by springs on the pin 13, one above, and one below the extension 15 and compressed by a nut 18 and locknut 19 on the upper end of the pin 13. Alternatively, friction damping may be employed. The front axle unit carries stub axles 21 journalled on which are front wheels 22, and also carries contact slippers 23, Fig. 4 hinged at 24 to the axle beam 25 and pressed against the conductor rail by a spring 26 engaging insulated pillars 27 on the slipper body. A tongue 30 projecting from the slipper 23 engages the underside of the conductor rail 31. Alternatively the guiding friction may be separated from the current-supplying friction. The front axle beam 25 and stub axles 21 may be of moulded composition or of metal. The electric motor Fig. 11 comprises a horseshoe magnet 51 fixed to the body part 6, an armature shaft, and a commutator 59 to which current is conveyed by brushes 62 carried on arms 60 hinged to a fibre block 61. The armature shaft and rear driving axle bearings are lubricated by felt pads soaked in oil and pressed on the ends of the armature shaft and surrounding the axle 43. Reduction gearing comprises gears 66, 67 on the armature shaft and rear axle respectively.

Abstract: 1402571 Data processing G H MITCHES A E JEFFERY and P T MITCHES 5 Jan 1972 [6 Jan 1971] 501/72 Heading G4A Data processing apparatus is arranged to examine portions of text, e.g. lines, to determine when the first non-space character represents an identifier for that portion, and to store the identifiers thus found. As described, statutes, regulations and the like which are conventionally divided into numbered or otherwise identified sections, subsections, clauses and so on, are examined line by line, each line being notionally divided into blocks in which the various identifiers normally occur following an indentation or series of spaces. Numeric, alphabetic and roman numeral identifiers may be recognized, each recognized identifier being stored in a storage cell of appropriate identifier rank, higher rank identifiers remaining unchanged and lower rank identifiers being reset. When no identifier is detected in a line, a line count may be incremented and appended to the identifiers to complete the line identification. The stored identification, including line count if necessary, may then be recorded together with the associated line of text. The arrangement enables display retrieval of particular portions of text by reference to the identifiers, as is usual with text divided into sections &c., rather than by reference to line number. Comments inserted in the text may be identified by a similar process, and selected portions of text and/or comments may be retrieved. Specification 1,402,572 is referred to.

Abstract: 458,327. Electric battery lamps. GELARDIN, A., 450, West 24th Street, New York, U.S.A. Jan. 10, 1936, No. 888. Convention date, July 5, 1935. [Class 39 (ii)] An electric-battery lamp or flashlight is provided with an end enclosure 21 of lighttransmitting material formed with a recess to receive and engage at least a portion of the lamp bulb. The member 21 preferably consists of a translucent frustoconical shell or globe formed at its lower end with a substantially cylindrical recess which tapers inwardly at its upper end and may extend as an axial bore right through the member. Screw-threads 23 on the lower end of the member 21 engage indentations 9 arranged helically on the inner periphery of a metal battery-casing 5, the lower end of the casing being provided with indentations 11 arranged similarly to engage a screw-threaded plug 15 which, in its lower position abuts against a flange 13 on the bottom of the casing. The battery 7 is located between the plug 15 and a tapering helical spring 31 which, at its lower end, abuts against either or both the zinc shell 33 of the battery or the metal casing 5, whilst the upper end of the spring provides a socket for the screw-threaded base 29 of the lamp bulb 27, which is thus held within the bore of the translucent shell 21. The battery circuit is closed to light the lamp by screwing inwardly the plug 15 by means of an external ring 19, the spring 31 being thereby compressed to bring the middle electrode 35 of the cell into contact with the middle contact 37 of the lamp.
