Title: Production of textured artwork
Inventor: HOUSSIAN VAZGEN JOHN
IPC: B44D5/00
Filed: 1991-05-01
Abstract: Textured effects may be produced, e.g. using felt tip art markers, by providing on a paper substrate a texture pattern in an essentially invisible material which nevertheless markedly alters the absorption characteristics of the substrate surface. Of particular effectiveness are so-called bleed proof marker papers with an invisible texture pattern printed on one side. When marked with a felt tip marker, a textured pattern appears as a result of differential absorption. The hidden texture pattern may be applied by various printing methods, e.g. lithographic printing using a clear or white varnish or extender. <IMAGE>

Title: A conductive guide rail for a printed circuit board.
Inventor: ITO FUMINORI
IPC: H05K7/14
Filed: 1992-07-15
Abstract: A guide rail (1) for a printed circuit board and for mounting in a partially conductive housing, comprises an electrically conductive guide member (3) and an electrically insulative fixing member (5). The guide member (3) is inserted into a receiving portion of the fixing member (5), by way of an inlet (19) formed in the bottom thereof. In this condition, electrical contact members (9) of the guide member project outwardly from the inlet. The fixing member (5) is then secured to the housing by way of fixtures (27). Since an operator only touches the insulative fixing member (5) to perform the guide rail mounting, corrosion of the guide member (3) is prevented. The contact members (9) are resilient and deflect toward the receiving portion of the fixing member (5) when the fixing member is secured to the housing, thereby establishing an intimate electrical contact with the conductive portion of the housing. Since the fixing member is of insulative material, short circuiting of the printed circuit board is prevented even if a member which supports the board in places happens to contact the fixing member. <IMAGE>
Patent GB-2269073-A (GB)
Title: Remote telephone line tester
Inventor: HOBBS CHRISTOPHER WILLIAM LEWI
IPC: H04M3/30
Filed: 1992-07-23
Abstract: A telephone subscriber loop is tested by applying an electrical impulse across the legs of the loop and determining the nature of the resulting transient voltage due to current in the loop. The impulse may be provided by reversing the polarity of a power supply to the loop. The transient can be measured by a differential amplifier AMP coupled across a resistor R41 in series with the loop. Typically the maximum voltage, the time taken for the voltage to decay to a particular fraction of the maximum and the long term residual voltage are measured. These measurements are returned to the exchange to identify fault conditions in the loop. The arrangement can be used in systems in which part of the communications path between the subscriber and the exchange comprises a fibre optic waveguide. Apparatus can be installed in a subscriber line card at a street distribution unit. <IMAGE>
Patent GB-2272969-A (GB)
Title: Thermal storage device
Inventor: ELLIS GORDON
IPC: F28D20/02
Filed: 1992-10-21
Abstract: A thermal storage heater employing phase change material (PCM) as the storage material. A mass of this material, which crystallises as the temperature falls to give out heat of crystallisation, is contained in a housing on one interior face of which a sheet or slab of foamed silicone rubber is fitted. Electric elements supply heat to the PCM during a low price period and the heat is given out during a high price period. As the PCM passes through its phase change it increases in volume in assuming the crystalline phase. This volume increase is accommodated by the resilient silicone rubber. The sheet of silicone rubber may be separated from the PCM by a sheet of metal. <IMAGE>
Patent GB-928873-A (GB)
Abstract: 928,873. Mixing appliances; control systems. NOVO INDUSTRIAL CORPORATION. Dec. 29, 1961 [Jan. 5, 1961], No. 46768/61. Class 86. An apparatus for dispensing a mixture of e.g. synthetic resin and hardener has an electric control system which, in addition to providing a normal operator-controlled dispensing cycle, (a) initiates an automatic emergency dispersing cycle, when the machine is inactive, after a predetermined time interval less than the setting time of the mixture, (b) sounds an alarm a short time before such initiation, (c) provides a visual indication that such automatic emergency dispensing has taken place, (d) sounds an alarm should the operator de-energize the apparatus without first initiating a purging cycle. In Fig. 1, lines 6, 8 supply the active materials and 10 the solvent to a selecting means 11 and thence to a mixing chamber 12 and dispensing nozzle 4. A foot switch 14 (see also Fig. 2) initiates a normal dispensing cycle by means of a control means 16, Fig. 2. The apparatus has also an adjustable time-setting mechanism 24 for the timer 26, and selector switches 28, 30 for a pair of stepped contacts 28<SP>1</SP>, 30<SP>1</SP>, Fig. 2. These count the number of units of material to be dispensed by the emergency cycle and are controlled as by limit switches 88, 90 actuated by the respective pump strokes. The timer 26 comprises a motor 44 driving, through an electro-magnetic clutch 46, timing mechanism which controls switches 48, 50; these move in sequence so that the alarm 52 is sounded a short interval before the emergency dispensing cycle is initiated, whereupon the pilot light 20 is illuminated. The timer resets automatically after operation or on depression of the foot switch 14. De-energizing of the apparatus by opening the switch 34 will sound the alarm 52 unless a purging cycle has first been initiated by moving the switch 54 to connect with line 56, and depressing the foot switch 14; the switch 54 being connected to the solvent selector. Specification 772,818 is referred to.

Title: Active fiber for optical signal transmission
Inventor: GARMAN JONATHAN D
IPC: H01S3/067
Filed: 1993-09-21
Abstract: An active optical fiber for optical communications systems comprises a doped transparent core surrounded by a transparent cladding of lower refractive index and pumped by light through the cladding to produce gain of an input optical signal. Repeaters along the fiber optic communications system are not required. The core may be doped with a lasing material of the same type used in the diode laser transmitter. The lasing dopant has the greatest density in the core center, and is diffused outward into the cladding. Pumping may be by radium fluorescent paint coating (72) (Fig 4) with reflector (74) (Fig 5) or an electroluminescent coating (78) (Fig 6) such that upon the application of voltage along the length of the fiber, the electroluminescent material generates photon energy and pumps the dopant within the core to achieve lasing. Segmentation via shorting connectors (135)(Fig 9) counters breakdown of insulating layer (80). Filter applications are disclosed for use with wide band transmitters (eg LEDs). An elliptical mirror system may be used (Fig 3). <IMAGE>

Abstract: This system uses paper or lightweight board stock, in sheet, pad or book forms where the upper surfaces are pro-applied with low-tack (releasable) adhesive (A) allowing the data and images (B) to be secured by light pressure only for storage and release as required. The untreated under surface (C) protects the new and succeeding glued surfaces until it is used, each page peeling away to continue the process until the pad or the file or the book is filled or used up. The adhesive is distributed in a pattern e.g. strips or dots, appropriate to the differing functions of the system. The books, pads, sheets and boards are in sizes appropriate to individual needs and in conventional sizes to fit with existing filing systems such as 'A' sizes, diaries, etc. The adhesive is omitted from the top sheet of any stack in order to provide a protective 'cover' sheet. <IMAGE>
Patent GB-2284359-A (GB)
Title: Jigsaw puzzles
Inventor: HART PETER THOMAS JOHN
IPC: A63F9/10
Filed: 1993-12-01
Abstract: Jigsaws employ combinations of audio clues and accompaniments to indicate the correct inter-relationship of the pieces and/or provide feedback upon completion of the jigsaw. The clues and accompaniments are used in addition to, or as substitutes for, a visual picture on the jigsaw surface and the lugs and indentations on the jigsaw pieces. The sounds may be generated by mechanisms in the pieces of the jigsaw and/or in a base or a base and surround, on which the jigsaw is assembled. Where the audio clues and accompaniments replace lugs-and-sockets, regularly-shaped jigsaw pieces may be used which can be physically assembled in more than one arrangement, but only the correct logical arrangement produces the sound accompaniment indicating the correct arrangement. The audio clues may be associated either with the jigsaw pieces or with the boundaries of the pieces.
Patent GB-2288255-A (GB)
Title: Write request interlock.
Inventor: WATT SIMON CHARLES
IPC: G06F1/12
Filed: 1994-04-07
Abstract: A CPU core 4 can operate at either an internal clock frequency fclk or an external clock frequency mclk. When operating at the internal clock frequency fclk, write request signals are buffered in a write buffer 10. When operating at the external clock frequency mclk, write request signals are unbuffered. In order to avoid write request signals reaching a signal bus 6 out of order, an interlock is provided between the two paths so that any pending write request signals in the write buffer 10 will serve to hold off any write request signals that may issue through the other path. When a write request signal generated at the external clock frequency is blocked, this serves to stall the CPU core 4 since the blocked external clock write request signal may give rise to an externally generated abort which would alter subsequent processing. <IMAGE>
