Title: Device for determination of particle size distributions.
Inventor: WITT WOLFGANG DR
IPC: G01N15/02
Filed: 1993-08-25
Abstract: Apparatus for determination of particle size distributions comprises a laser 10 which radiates parallel light through a measuring zone 14. The light beam diffracted at particles in the zone 14 is imaged by an imaging device 18 onto a photo-detector 20 which is coupled to an evaluating unit 22. The imaging device 18 is provided with several different focal lengths which can be selectably brought into the beam path to measure different ranges of particle sizes. One or more trial measurements are automatically made to find the optimum focal length for the size distribution being measured, i.e. which can just measure the largest particles, thereby to maximise resolution. An initial measurement at the longest focal length can for example determine the uppermost size fraction present and the focal length appropriate thereto. Distance b to the photodetector is varied to match the selected focal length. <IMAGE>

Title: Vehicle security system with secure valet switch
Inventor: DRORI ZE EV
IPC: B60R25/10
Filed: 1994-02-16
Abstract: A vehicle security system has a secure valet/programming switch 90. To either enter the system valet mode (i.e. switching off the security system), or select a function via the valet/programming switch, the user must first enter a valid personal access code via the switch. To prevent an intruder from deciphering the personal code by trying various codes, the system ignores, after a preset number of successive invalid entries, further switch inputs for a preset period of time. When attempts to decipher the code are detected, the alarm is tripped, and the siren will sound. To accommodate various drivers of the same vehicle, more than one valid code can be stored in the system. Any of the personal access codes may be changed any time, but after the user's present code is entered. <IMAGE>

Title: Mobile radio with transmit command control
Inventor: FERNANDES VERNON JULIAN
IPC: H04W28/02
Filed: 1994-03-23
Abstract: A mobile radio for operation in a system having a discontinuous transmission function, for example GSM, transmits silence descriptor (SID) frames when the transmitter is active (i.e. the PTT button has been depressed) but there is no voice input signal. The transmitter of a second mobile radio is initially suppressed but later enabled (80) when a respective receiver (50) detects SID frames on the radio channel when a transmit command is input (85). In this way the first radio user does not "hog" the channel. High and low priority mobile radios may be arranged to activate their respective transmitters according to different criteria when SID frames are detected. <IMAGE>

Title: Gas valve
Inventor: WRIGHT ALAN THOMAS
IPC: F23N5/04
Filed: 1994-07-18
Abstract: A gas valve in which a valve member 30 and/or a valve seat 33 are carried by bimetallic members 27, 28 which can be heated by a heating element 26 to open the valve. The valve may be the second modulating stage of a compound valve in which the first stage is a solenoid actuated valve 61. When the element 26 is heated the bimetallic members bow towards each other so that the valve member is moved away from the seat 33. The degree of opening and thus the gas flow rate is dependent on the degree of heating. If there is excessive gas pressure or excessive temperature, the valve member is pressed against seat 37 to close the valve. There may be two of the gas valves in series. The biassing force of a spring 66 in the solenoid actuated valve 61 may be replaced or augmented by a permanent magnet (71) Fig 6. <IMAGE>

Title: Method of producing aperture grill
Inventor: MAKITA AKIRA
IPC: H01J9/14
Filed: 1994-07-20
Abstract: A method of producing an aperture grill of a CRT display device which is a 20 to 100  mu m thick comprises exposing a metal plate (1) with front and rear surface photoresist layers (2,3) to a mask (4) with a single broad slit pattern and a mask (5) with two adjacent, narrow slit patterns. The photoresists (2, 3) are developed to produce patterns (2a, 3a). Thereafter, etching is carried out through patterns (3a) to produce cavities (7) in the metal plate. Then, a reinforcing, etchant-proof film (8) is attached to the resist layer (3) to cover the rear cavities, and thereafter etching is carried out on the other surface of the metal plate via pattern (2a) so that the cavity formed meets with the cavities (7) with the etchant flowing into the rear cavities, to produce a single through slit (10). Thereafter the reinforcing film (8) and resists (2,3) are removed. The method makes it possible to easily produce slits of dimensional accuracy. <IMAGE>

Title: Antenna system having plural antenna portions
Inventor: SADAHIRO KEIICHI
IPC: H04B1/38
Filed: 1994-09-06
Abstract: An antenna system for portable radio equipment is composed of first and second antenna portions (19, 20). The first antenna portion (19) has a loading section (21) and is provided at a position projected from a casing even when the antenna system is retracted and is also coupled to a power-feeding portion (12). The second antenna portion (20) is connected to a lower end of the first antenna portion (19) to be containable in the casing, and is coupled to the power supply via stopper (8) at the base end portion when the antenna is extended. The second antenna portion (20) is electrically insulated from the first antenna portion (19). Since the first and the second antenna portions (19, 20) are electrically insulated from each other, no power-feeding to the contained portion will take place when the antenna is retracted. Modified antenna portions are disclosed employing strip conductors. <IMAGE>
