Title: Electric supply systems for road vehicles
Inventor: GAYLER GEORGE ALFRED
IPC: B62J6/00
Filed: 1954-09-13
Abstract: 778,629. Vehicle supply systems. WIPAC DEVELOPMENT, Ltd. June 29, 1955 [Sept. 13, 1954], No. 26504/54. Class 38 (4). An electricity supply system for road vehicles comprises an A.C. generator connected to terminals 10, a rectifier 11, and a battery 12 adapted to be charged from .the output of the rectifier. The connections to an ignition coil 9 and lamps 20, 21, 22 are controlled by an ignition switch 13 and a lighting switch 16. The arrangement is such that when the ignition switch is in the upper " on " position and the lighting switch is in the lower " off " position, a dummy load represented by a portion of resistor 23 is connected to the output of the rectifier. This prevents the development of excessive voltage across the rectifier should the battery be removed or accidentally open-circuited. When the lighting load is varied, the switch 16 is adapted to connect a suitable portion of the resistor 23 in parallel with the lamps to maintain a substantially constant load upon the generator for all settings of the lighting switch. The adjustment of the ignition switch to the lower " emergency " position effects the disconnection of the resistor so that the output of the rectifier is supplied directly to the ignition coil.

Title: An improved electric time switch
IPC: G04F1/06
Filed: 1931-09-23
Abstract: 376,553. Gravity switches; snapaction switches ; retarding action of switches. ELLINGER, O. K., Dorfhain, near Dresden, Germany. Sept. 23, 1931, No. 26534. Convention date, June 10. Addition to 376,524. [Class 38 (v).] In a time switch of the type described in the parent Specification, the sandglass 109 and weight 107 are revolved through the required 170" by means of a tooth 28 on the pushbutton 112 engaging the slightly-twisted central portion 20a of a strip 20 carrying the sandglass and weight. The tooth moves in a line slightly above the axis 105 on which the strip 20 revolves, but owing to the twist it engages below the twisted central portion 20a and after turning the latter through the 170‹ rests lightly above it and prevents further rotation until the pushbutton is released. The pushbutton 112 when depressed, also moves a switch lever 32 against spring action into the closed position where it is held locked by the end 33 of the lever 32 engaging behind a stop 30b on an arm 30. The lever 32 carries a contact member 35 which bridges contacts 41, 42, and a quick "make" is effected by an insulating strip 37 which at first comes between the contact 35 and the contact 41, but at the end of the contactclosing movement is whisked away. To effect this, the strip 37 is pivoted to the arm 32 and has an end 38 which at the end of the movement engages a fixed portion of the base. The lever 32 is released and the switch opened by the weight 107 falling on the arm 30 and rotating it about its axis 29 against the action of a spring. The arm 30 may also be moved into releasing position by pressing a rod 39. In a modification, Fig. 14, the weight consists of a member 207 sliding on a rod 206 and the ramp which holds it in its upper position until the time limit has expired consists of a roller 45. Centrifugal force holds the weight in its outward position until the roller 45 is reached. In another modification, Fig. 15, the weight 207<1> is mounted on an arm 49 which is moved through 170‹ about the axis 431 by a crank 47 and held against return by a spring strip 50 past which it brushes at the end of its movement.

Title: Improvements in illuminated liquid level indicators
IPC: G01F23/02
Filed: 1957-08-26
Abstract: 820,473. Indicating liquid levels. KLINGER A. G., R. Aug. 26, 1957 [Sept. 4, 1956], No. 26909/57. Class 123(1) A liquid-level gauge has a body portion 1 having a liquid channel 13 closed at the front and rear by plane-parallel glass prisms 6 secured to the body by cover plates 2 and protected from corrosion by mica sheets 9. The rear cover plate has a slot 16 through which passes a strip of light from a source 19 whilst the front cover plate has a slot 17 through which the liquid level is observed. The channel 13 is of parallelogram cross-section and is set an an angle to the plane at right angles to the front and rear surfaces of the body whilst the channels 16, 17 are set at a slightly greater angle to the said plane. Due to the different refractive indices of the gas and liquid in the channel 13 the portions of the light strip respectively entering the gas and liquid are deflected through different angles. The angle of the channel 13 is chosen so that whilst one light portion passes through the channel and leaves by way of the second prism, the other falls on the wall of channel, either the liquid column or the gas appearing as an illuminated strip allowing the level to be easily observed. For further ease of reading the face of the indicator may be illuminated to a brightness value between that of the luminous and dark strips.

Abstract: 1,142,636. Heat-treating polyethylene terephthalate filaments. IMPERIAL CHEMICAL INDUSTRIES Ltd. 22 June, 1966 [25 June, 1965], No. 27053/65. Heading B5B. In a process for heat-treating oriented crystalline polyethylene terephthalate filaments by causing them to travel from feed means to takeup or winding means rotating at predetermined peripheral speeds (which may be the same or different) through a heating zone or zones the period of dwell of the filaments in the heating zone or zones is 1 to 12 seconds and the heating zone is equipped with heat exchange means maintained within Œ1‹ C. of a predetermined temperature in the range 251‹ to 264‹ C., i.e. within a range of temperatures 14‹ to 1‹ C. below the melting temperature of the filaments. The heat exchange means comprise a bed of hot solid particles which are preferably fluidized by a current of gas which itself may be heated, e.g. electrically. The particles may have a diameter of about 1 mm. but not below 50 microns and may be heated by means of coils immersed in the bed of particles or by circulating heating fluids through a jacket around the container of the bed. They may also be heated by electric heating elements immersed in the bed or forming the walls of the container. The filaments may either be allowed to shrink 3-4% of their initial length during their passage through the heating zone or held under just sufficient tension during their passage through the heating zone to prevent them from shrinking. The dwell period of between 1 and 12 seconds in the heating zone is longer the higher the denier of the filaments. The treated filaments may have a tenacity of at least 6 g.p.d., an extension of less than 15%, a shrinkage of less than 4% Œ 0À2% and a 2% modulus of at least 100 g.p.d.
