Patent GB-2135229-A (GB)
Title: A method and an apparatus for controlled-atmosphere brazing of high-alloy Cr-Ni steel components
Inventor: SALZBERG BERND-PETER
IPC: B23K35/30
Filed: 1984-01-19
Abstract: It is the object of the invention to render possible the easy and reliable joining of high-alloy Cr-Ni steel components under site conditions without the need of any separate chemical or mechanical pre-treatment of the oxide layer adhering to the metal. According to the invention, this is brought about in that the brazing joint is heated according to the direct electric resistance-heating principle whilst surrounded by a protective chamber. There will then flow through this arrangement during the heating phase and the subsequent cooling phase an inert gas having a maximum contamination of 100 ppm. The chamber volume must not exceed a maximum of 200 cm<3> but must be 20 to 30 times larger than the component volume involved in the brazing process.

Title: Fresh milk hot drink vending machine
Inventor: TAYLOR DAVID
IPC: B67D1/00
Filed: 1984-06-13
Abstract: A drink vending machine includes a supply (10) of refrigerated fresh milk for dispensing into hot drinks produced by the machine. To prevent spoiling of milk in pipework (15, 16) leading from the supply (10) to milk dispensing nozzles (13, 14), the replaceable pipework (15, 16) passes through reversible peristaltic pumps (11, 12) and the nozzles (13, 14) have hot water connections (23, 24) controlled by valves (25, 26). During dispensing of a hot drink containing milk one of the pumps (11, 12) is first run forwardly to dispense the required volume of milk, and then in reverse to withdraw milk in the pipework to the supply 10. Finally the associated one of the valves (25, 26) is operated so that hot water washes milk from the nozzle into the cup. <IMAGE>

Title: Pipeline liquids sensor
Inventor: LAMB JOHN GARTH
IPC: G01N21/43
Filed: 1984-07-20
Abstract: The onset of the passage of a low refractive index liquid down a pipeline is determined with the aid of a length of transparent glass fibre spliced between two optical fibres respectively connected with an optical source and a photodetector. The transparent glass fibre is provided with a cladding of higher refractive index and hence fails to transmit light unless permeated with a low refractive index liquid flowing in the pipeline that reduces its refractive index beneath that of the glass.

Title: Digital map generator and display system
Inventor: BECKWITH PAUL B
IPC: G06T15/00
Filed: 1984-09-10
Abstract: In a digital information storage and read-out system, digital elevation and cultural terrain map data is read from a magnetic tape (10) in compressed form into an intermediate memory (20) which operates as a speed buffer memory. The data in the intermediate memory (20) is read out to a reconstruction processor (30) in which the compressed data is reconstructed and applied to a scene memory (35). A navigation computer (100) determines the instantaneous position of a vehicle with respect to the terrain and controls the reading of data into the scene memory (35) in blocks with the vehicle position occupying a center of scene location. in order to provide a heading up display of the terrain, the data in the scene memory (35) is read out at an angle to its north-up storage orientation and interlaced scanning of pixel data in the scene memory improves resolution and enhances line display. The data read out of the scene memory controls the generation of video control signals to effect a display of the elevation and cultural data as a moving map related to the vehicle position. <IMAGE>

Patent GB-2190566-A (GB)
Title: Terminal apparatus
Inventor: OSDAMAR M
IPC: H04J3/14
Filed: 1986-05-16
Abstract: To permit fault detection in terminal apparatus of a TDM network, echo channel bits (E-bits, Figure 1) are monitored to determine if an apparent collision with another terminal on the network has occurred. Each time data collision is indicated a counter (2, Figure 2) is incremented, the counter (2) being periodically decremented. If a predetermined count is reached indicating apparent collisions occurring at higher than expected rates a fault indication is given. This enables terminal apparatus on a TDM network to detect faults which mimic collisions.

Title: Surveillance arrangement
Inventor: FISCHER KLAUS
IPC: F42B23/24
Filed: 1986-07-21
Abstract: The sensor wire (10) which takes up mechanical vibrations of an object to be detected is mechanically coupled with the piezoelectric transducer (13). The transducer (13) consists of a section (14a) of a coaxial conductor (14) comprising an inner signal wire 15, a piezoelectric jacket 16 and an outer conductor layer (17) which acts as a screen. Mechanical vibrations of the sensor wire (10) produce in the transducer (13) deformations which lead to voltage signals in the inner wire. Electromagnetic fields, which the sensor wire (10) intersects, are kept away from the inner wire (15) and the outer conductor layer (17) so that such disturbing fields do not generate any electrical signals. <IMAGE>

Title: Controlled illuminated display
Inventor: JONES JOHN WINSTON DELAHAY
IPC: G02B6/00
Filed: 1987-11-27
Abstract: A display unit has a transparent front panel 10 one surface 11 of which carries reflective markings 12 to 15 that are illuminated by internal reflection in the panel from edge-mounted bulbs 31 to 34. Behind the panel 10 are located light-emitting display devices 20 and 21 such as provided by LED's. Illumination from the bulbs 31 to 43 is controlled by manually adjusting a rheostat (36). The brightness of the display devices 20 and 21 is controlled by means of two photodiodes 51 and (52). One photodiode 51 responds to the level of ambient light falling on the front panel; the other photodiode (52) is shielded from ambient light and responds to light from an additional bulb (40) connected in parallel with the edge-mounted bulbs and having the same illumination characteristics. The brightness of the display devices 20 and 21 is thereby automatically decreased when ambient light levels fall and increased when the markings 12 to 15 are brightly illuminated, so that they are not masked by bright markings. <IMAGE>

Title: Signal suppression circuits
Inventor: SNOW JOHN RICHARD COBDEN
IPC: H03J7/00
Filed: 1988-03-12
Abstract: An intermediate frequency stage signal suppression circuit for a radio frequency receiver is provided for the suppression of one or more relatively large signals of different frequencies occurring within a wideband input to the arrangement including a number of relatively small signals of still further different frequencies. The arrangement comprises mixer means 1, 2, 3 and associated controlled synthesiser means 4, 5 and 6 which mix down the signals within the wideband input to within a predetermined intermediate frequency band. Detector means 10 are provided for detecting and measuring the frequency or frequencies of any relatively large signals in the wideband signal and identifying them to control means 1 for the synthesiser means 4, 5, 6. The frequency output(s) from the synthesiser means will be varied in order to cause the output from the mixer means 1, 2, 3 to be notched down or filtered out by notch filter means 8, 9. The circuit reduces large signals to a level which does not produce spurious signals in a signal analysis arrangement or removes unwanted signals eg jamming signals. <IMAGE>
