Patent GB-2160016-A (GB)
Title: Incandescent lamps
Inventor: RIGDEN SYDNEY ALFRED RICHARD
IPC: H01K1/14
Filed: 1985-06-05
Abstract: Conventional incandescent filament lamps have an even number of filament sections so that the connections of the filament to the support wires are both at the same end of the bulb. It is found that in the horizontal position such bulbs burn out very quickly compared to their lifetime in the vertical position. Hence a lamp is provided with seven filament section with the connections to the support wires being at opposite ends of the bulb. This significantly prolongs the lifetime of the bulb when in the horizontal position and also provides an improved light distribution. <IMAGE>

Title: Concurrently measuring a plurality of light signals
Inventor: TSUCHIYA YUTAKA
IPC: H01J31/50
Filed: 1986-02-10
Abstract: An instrument capable of concurrently measuring ultra-high-speed light signals on a plurality of channels comprises a streaking tube (7), having in order a photocathode, deflection electrodes 75, a slit plate and a phosphor layer, electrodes 75 being arranged to deflect electrons on application of a sweeping voltage (15), the slit plate having its slit perpendicular to the direction of deflection. Optical means 4, 5, 6 transient repetitive light signals to a section of the photocathode perpendicular to the direction of deflection. The deflection voltage is synchronized (9, 10, 12, 14) with the light signals, its phase being successively incremented. A photodiode array 8 perpendicular to the deflecting direction feeds processing means (17, 18, 30, 32, 34). The instrument can also measure periodically the mechanical distortion of an object on which a pulsed laser beam is incident and time-serial data may be output as parallel data on a parallel time base. <IMAGE>

Title: D.C. motor control arrangement
Inventor: KANEDA JUNICHIRO
IPC: B60L3/04
Filed: 1986-03-06
Abstract: A control arrangement for rolling stock driven by a separately excited d.c. motor comprises a field chopper for controlling the motor field current and a field switch for switching the field current direction. The field chopper is controlled by a field chopper control circuit 26 and the field switch by a control circuit 27. To avoid a high voltage transient voltage being generated when field current is interrupted during regenerative braking, the control is arranged to maintain operation of the field switch for a predetermined time delay following stopping of operation of the field chopper, whereby the field current can decrease relatively gradually.   <IMAGE>

Patent GB-2195181-A (GB)
Title: Ultrasonic distance measuring device
Inventor: SHELLEY WILLIAM PETER
IPC: G01S7/529
Filed: 1986-09-23
Abstract: There is provided a non-contact distance measuring device in which a sound wave (106) is transmitted towards a target object (107) with the time taken for the second wave (106) to travel to and from the target object (107) being used to determine the distance. The distance is determined by processing means which include a variable gain amplifier the gain of which is increased automatically with propagation time of the sound wave. Provision of the variable gain amplifier results in the degradation of the sound wave during travel to and from the target object (107) being compensated. <IMAGE>

Title: Refrigerated display cabinet
Inventor: FONDEL FRANZ
IPC: A47F3/04
Filed: 1986-12-22
Abstract: A refrigerated display cabinet has a unit comprising a blower 52 combined with a barrier 50 which unit is positioned easily by hand in a channel of the cabinet. To avoid adhering of the unpacked meats to the supporting plates 32, the direction of the blower is selected, such that the refrigerated air flow leaving a wet evaporator 34 first takes-off the heat from the food to be refrigerated across its exposed surfaces, and subsequently passes along the undersides of the plates 32 at a slightly higher temperature, to be finally urged by the blower into the wet evaporator. With the unit removed from the display cabinet cooling is effected by convection (Fig. 1). <IMAGE>

Title: Member having improved surface layer and process for making the same
Inventor: NATORI TATSUO
IPC: B22D19/08
Filed: 1989-05-08
Abstract: A process for making a metallic member having surface wear resistance by casting, which comprises placing ceramic particles (such as SiC particles) with or without an admixture of metallic powder (such as iron-based particles, e.g. stainless steel particles) in a predetermined position internally of the casting mould and pouring molten metal (e.g. molten iron-base metal, particularly molten cast iron) thereinto, thereby forming a wear-resistant layer at a desired position on the surface of the casting. The metal and ceramic particles form intermediate material (14 or 14a) around the ceramic particles (13). In the case where metallic powder had been compacted with ceramic particles, the intermediate material (14, Fig. 2) results from reaction of the ceramic and molten metal from the powder, and the cast metal (15) forms a base body. In the case where ceramic particles alone had been compacted, the intermediate material (14a, Fig. 3) results from reaction of the molten metal cast (14b) with the ceramic. …<IMAGE>…

Title: Method for manufacturing anti-static cathode ray tubes
Inventor: IWASAKI YASUO
IPC: H01J9/20
Filed: 1989-09-25
Abstract: In an anti-static coating provided on the faceplate of a cathode ray tube, and consisting for example of a silica matrix with a conductive filler of SnO2 or In2O3 and additives of P or Sb, the concentration of the conductive filler dispersed in the coating solution applied to the face plate is so set that the surface resistance of the coating lies within the range 5 x 10<7>  OMEGA  to 1.0 x 10<11>  OMEGA . The coating is baked at 380 DEG  to 450 DEG C preferably as part of a conventional heat treatment during tube manufacture, e.g. during panel bake, frittered glass sealing or on evacuation. As shown the coating is applied from nozzle 116 to the faceplate 104 while it is rotated in a spin-coating machine 114 and a salvage cap 115, which may be circular or the same shape as the tube faceplate and which collects excess coating splashing off the tube as it rotates, is itself rotated in synchronism with the tube to obviate problems of uneven coating and splash-back encountered in prior devices in which the salvage cup does not rotate.
