IPC: G06F17/50
Filed: 1991-05-30
Abstract: A method of verifying track spacing of pcb layouts in relation to a set of predetermined minimum distances, eg. track-track, track-land etc. The method eliminates false errors caused by non-parallel tracks by applying other (eg. track-land) criterion to pcb tracks identified as being non-parallel.

Title: Hollow waveguide switch
Inventor: SPINNER GEORG
IPC: H01P1/12
Filed: 1991-10-07
Abstract: A hollow waveguide switch for connecting oppositely disposed terminals A to D, arranged in pairs, for right-angled waveguide switches, has a rotor (4) which is rotatable in corresponding stages. Manufacture of this rotor is considerably facilitated if, instead of the hitherto customary continuous channels, pockets (7, 8) are provided which are open at the sides, so that the respectively oppositely disposed inner wall region of the housing forms the second long right-angled side of the hollow waveguide switch. At the same time, the diameters of the rotor and the volume thereof are reduced, and also the diameter of the hollow waveguide switch as a whole. The length l of the innermost walls of the pockets satisfies the relationship  lambda H/2<¦< lambda H, where  lambda H is the hollow waveguide wavelength. <IMAGE>

Patent GB-2278022-A (GB)
Title: Circuit for detecting charged state of a battery by sensing -DELTA V
Inventor: CHEN STEPHEN
IPC: G01R31/36
Filed: 1993-05-13
Abstract: A first input pin 11 of a comparator 10 works to constantly detect the voltage of a battery 20 being charged, and the detected voltage is transmitted, via voltage reduction resistors R1, R2 (R2 >> R1), to the second input pin 12 of the comparator 10 so as to charge a memory capacitor 30. A fixed-value voltage dropping unit 50 may be in parallel connection to the voltage reduction resistors R1, R2 to keep the voltage difference between the first and second pins 11, 12 at a small value. When a charged battery is charged to saturation and the voltage thereof drops, the voltages of the first and second pins 11, 12 of the comparator 10 drop at the same time, but the voltage at the second pin 12 is affected by the memory capacitor 30 and drops at a lower speed than the first pin 11 causing the comparator output to change state and turn off the charger 40. The unit 50 may be a diode or a zener diode. The battery voltage may be applied to the detector via an amplifier (60),(Fig 3), to improve the detection sensitivity. <IMAGE>

Title: Chair with synchronised seat and back movement
Inventor: HALL CRISPIN
IPC: A47C1/032
Filed: 1994-08-03
Abstract: A chair, especially of the "office" type, has a seat squab and a seat back which can be tilted. The tilting movements are linked, eg via a pin engaged in an "L" shaped slot so that in tilting the seat from a forward tilting sitting position to a level sitting position, the back moves through the same angle as the seat, but on further, reclining movement backwards the seat back moves through a greater angle than the seat squab, eg in a ration of at least 1:1.4. The increase in movement of the back can be made gradual by use of a cam or curved slot. The mechanism is spring loaded to the level position.   <IMAGE>

Title: Telecommunication systems
Inventor: MOLLER CHRISTOPHER HARDING
IPC: H04M3/58
Filed: 1995-03-06
Abstract: Most modern private telephone systems - known as, and referred to hereinafter as, Private Automatic Branch Exchanges (or PABXs) - provide many more facilities than do the normal public telephone systems. Unfortunately, while some of the latest public Exchanges have a limited number of these facilities, they are nevertheless severely restricted by comparison with PABXs. It would be very convenient to have the full facilities of a PABX (P) available to any telephone (T1) connectable remotely thereto by the public system (PTN1), and the invention seeks to permit this by suggesting the use, operationally interposed between the private system (P) and the public system (PTN1), of an interface (12) that allows the remote phone (T1) to send control signals through the public system (PTN1) to the private system (P) so as to cause the latter to operate in the manner required. <IMAGE>

Title: Linear actuators
Inventor: GIESEN NORBERT
IPC: F15B15/02
Filed: 1995-11-28
Abstract: A conventional rodded pneumatic cylinder is modified by the provision of an endless belt (8), one run of which is connected by a linkage (11, 12) to the outer end of the piston rod (5) and the other run of which is connected to a stationary mounting device (6) that slidably supports the cylinder. Upon actuation of the cylinder, the piston rod (5) and the cylinder body (2) move in the same direction relative to the mounting device (6) and the stationary structure. The effective stroke is therefore twice the normal stroke of the unmodified cylinder, i.e. the stroke of the piston rod relative to the cylinder body. <IMAGE>
