Title: Spark gap for pulsed gas lasers - has third electrode to reduce pulse rise-time by reducing self-inductance
IPC: H01S3/0973
Filed: 1980-04-08
Abstract: This spark gap is used to discharge a capacitor through a gas laser circuit to produce very short pulses of ultra violet light. The problem with conventional spark gaps used to supply pulses of a few nano-seconds is that the self-inductance of the gap extends the pulse rise-time, thus reducing the power of the pulse. The usual rate of rise of 10 to 40 kV/nano-second can be increased to greater than 60 kV/nano-second by adding a third electrode (4) separated from the two spark gap electrodes (2,3) by an insulated substrate (1). The third electrode is connected to one of the other two. The self-inductance is then reduced from a value proportional to the width of the gap to a value proportional to the thickness of the insulated substrate.

Title: Drill bit adaptor for chuck - is sleeve-shaped fitting positively over shank and inside chuck
IPC: B23B51/12
Filed: 1981-04-09
Abstract: The adaptor fits over the shank of a drill bit so as to couple it to the chuck of a portable power drill etc. It is basically sleeve-shaped (1), the interior being shaped so as to engage positively with the end of the shank (3), while the exterior is shaped so as to transmit torque from the chuck (4). It can be designed so that the rearmost end of the shank is clear of the rear internal end face, and can taper on the outside and/or inside, either of which can have a screw thread or axial splines, or a flat. There can be an end wall closing the interior.

Title: Fluorescent lamp ballast circuit powered by DC - has current limiting circuit which operates if lamp has not ignited within present period
IPC: H05B41/285
Filed: 1990-01-24
Abstract: The oscillator (1) which powers the fluorescent lamp (6) is fed by a d.c. source (3), via an on/off switch (2). The oscillator output, which is at a frequency of between 30 and 60 kHz, is fed via a capcitor (23) through the filament (4) at one end of the tube, through another capacitor (7), the other tube end filament (5) and a current sensing network (31, 32, 33). When the switch is set to the closed position, the circuit allows a high initial current. In normal circumstances, this current drops to a lower level when the lamp has 'struck'. If the lamp does not strike within a preset time, or if the oscillator output is short circuited, the value of a temperature sensitive resistance (32), changes, causing a thyristor circuit to reduce the current to a safe level. @(15pp Dwg.No.1/3)@.

Title: Reflective display device with light source - rotates matrix of separator mechanical elements to give either light or dark appearance to match good or poor ambient conditions
IPC: G09F9/37
Filed: 1990-11-30
Abstract: The section of the channels is pref. of a parallelogram form with the option of a plain or profiled internal region at the inner side or base of the channel. This region is not covered with dark, light-absorbing material. The form of the profile is arranged such that a shadow region is formed within the channel thus preventing light transmitted through the base of the channel escaping, when illuminated from the rear with the element orientated to produce a dark appearance. The opaque, translucent layer is pref. a material which evenly diffuses light falling upon it, such as white perspex, or a fluorescent material with which an ultra-violet light source can be used. A layer of dark paint is applied to achieve the dark, light-absorbing surface. A reflective paint coating may be applied underneath the dark surface to achieve a more even dark appearance where required. The channels may be produced by machining the form in solid material or by fabrication of the channel side strip elements from, e.g. sheet metal by pressing and bending.

Abstract: Known methods of transferring between centres the handling of an active connection between a user and a mobile terminal in a telecommunication system designed for mobile communication generally have the disadvantage that the routing obtained is inefficient. By investigating both a first route between a first switching centre and the user and a second route between a second switching centre and the user for common centres which are able to handle call control and connection control separately, of which the common centre situated nearest the first switching centre is designated as central intelligence point or, if the latter is not found, by designating the centre situated nearest the user as central intelligence point and then setting up a connection between a central intelligence point found in this way and the second switching centre, the most efficient routing is obtained. <IMAGE>

The driving part (19) of a clutch mechanism (18) is secured to the shaft (11) and the driven part (27) secured to the magnetic coupling (16, 16 min ). The driving part comprises a cylinder (19) releasably held retracted by a pin (20) engaging behind a shoulder (21). With the cylinder (19) thus retracted the casing (13) is mounted on the meter. When the meter is first run the rotation of shaft (11) releases the pin (20) so that the clutch (18) engages.

Filed: 1989-04-27
Abstract: The method and system of compressing and decompressing digital color video data in a video communication system utilizes a digital color video signal having three video color components, and involves the determination of a predetermined number of the most visually significant combinations of color components in a picture frame, and the encoding of the color components as compressed color codes in a series of run length and compressed color code combinations. Line-to-line differences and movement of edges and segments of the picture frames are determined, and frame-to-frame differences are also encoded to reduce the amount of information to a minimum. Further statistical encoding of at least a portion of the run length and color code combinations is also provided. The digitally compressed color component codes are decoded according to a look up table to form a table of the three digital color components for each run length, and the run lengths and corresponding color components are stored in an array in a buffer memory to represent the scan lines in a video picture frame.
