Title: Valve
IPC: F16K27/04
Filed: 1980-07-22
Abstract: The invention relates to a valve with a housing and a valve seat (10) located therein and comprising a frustoconical sealing surface (11), with which valve seat a movable valve member (6) is associated which is able to move on the valve seat towards and away from the latter, which in the closed position bears in a tight manner against the valve seat (10) and separates two apertures (17, 18) from each other in a tight manner, with at least one aperture connected to one of housing connections (15, 16). In order to be able to use the valve as a two-way valve and in particular for checking the tightness in the case of gas fired installations, a third connection not shown is provided in the housing (1) and is connected to the part (13) of the inside of the housing which is separated in a tight manner from the first two connections (15, 16) when the movable valve member bears in a tight manner against the valve seat (10). <IMAGE>

Title: A casting-core knockout machine
IPC: B22D31/00
Filed: 1981-01-15
Abstract: The removal of a disintegrable core from a casting is achieved by vibration, assisted by an air or water blast.

The latter is moved into engagement by a first ram (14) and firmly clamped by further rams (22, 23) so that even when vibrated the casting is not released. During vibration the fluid blast, augmented by particulate material, is applied to at least one aperture exposing part of the core. The core material may be recovered and used with the fluid blast to cleanse the casting. <IMAGE>

Title: Manufacture of carrier strip for electrical contact members
IPC: H01R43/00
Filed: 1981-01-16
Abstract: A carrier strip 32 for electrical contact members comprises an elongate metallic strip in which are formed a plurality of orifices 34, 50. The orifices are shaped to produce cantilevered portions 36 in the metallic strip which are deformable out of the plane of the metallic strip to permit the insertion between the strip and each cantilevered portion of an electrical contact member. The cantilevered portions may be U-shaped or L-shaped. The carrier strip has contact portions 12 and is formed by pressing. Contact legs 16 of the contact members are inserted between the cantilevered portions and the strip in line with each contact portion and welded at a position 18. A portion of the strip is then cropped out so that each contact portion is supported by a contact leg which, in turn, is supported on the strip by the cantilevered portion. <IMAGE>

Title: Sintered metal-glass compositions
IPC: H05K1/09
Filed: 1981-02-06
Abstract: In a method of producing a base metal thick film conductor, copper is mixed with glass frit and a vehicle, then printed on a non-conductive inert substrate e.g. by silk screening. The film is then dried, and a coating of boron in suitable paste or paint form having been mixed with a thixotropic organic vehicle is covered over the entirety of the substrate and film. The resulting product after a second air drying is then fired to bond the glass frit-copper as a thick film onto the substrate, with the copper particles being sintered throughout into a thick film. Superposed boron, where contiguous with the copper printing, is fused as a protective layer over the copper allowing the sintering of the copper and bonding with the substrate to occur without oxidation of the copper. Oxidized boron that covers portions of the substrate not occupied by the thick film is then washed away and the boron bonded to the copper remains as a protective coating. <IMAGE>

Patent GB-2080592-A (GB)
Title: Vibration and/or impact detection system
IPC: G08B13/02
Filed: 1981-06-29
Abstract: An inertial sensor (31) and a pulse shaper (33) produce a pulse train in response to sensed vibrations and impacts. A reference pulse generator (37) compares the pulse periods in the train with a reference period (tr) which is adjustable by an adjuster (47). Pulses of periods less than (tr) are fed via a vibration pulse separator (37A) and an AND gate (38) to an integrator (39) having an adjustable integration time to produce a vibration alarm if vibrations have at least a 50% duty ratio and occur in a burst of preset duration. Pulses of periods greater than (tr) are fed via an impact pulse separator (37B) to an impact pulse counter (49) which in response to a first pulse is enabled by a unit (52) for a 5s window period to count the pulses. A delay (120) and a inhibit circuit (121) disable the counter (49) for an inhibit period of ls after a delay of 20ms from the first pulse. An impact alarm is produced if a preset, selectable, number of pulses is counted in the 5s window minus the inhibit period. Any pulses occurring in the inhibit period are not counted but extend the window. In a further embodiment, the vibration alarm is produced by an integrator without taking account of duty ratio. In the further embodiment the impact alarm is produced in response to the number of pulses first occurring in each of a succession of windows without counting any successive pulse in each window. <IMAGE>

Title: Dimension of rectangular sheets
Inventor: PETTET RONALD SIDNEY
IPC: G07D7/182
Filed: 1982-11-01
Abstract: To measure the true width or length of a moving sheet, which may not be travelling with its leading edge perpendicular to the direction of motion, sensors are positioned along the feed path, two sensors being spaced in the feed direction and two sensors being spaced in a direction transverse to the feed direction. By measuring the period between signals from two sensors (e.g. S1, S3) spaced in the feed directions for the passage of the same edge of the sheet the velocity is obtained and by measuring the period between signals from one sensor corresponding to the passage of the leading and trailing edges of the sheet and the period between corresponding edge signals from two sensors (e.g. S1, S2) spaced transversely to the feed direction, the true dimension of the sheet perpendicular to its leading and trailing edges can be obtained, irrespective of skew. Folded or missing corners (Figures 2-4 not shown) can also be recognised by a four detector array. <IMAGE>

Title: The production of multiple coating systems
Inventor: KLUG WERNER
IPC: G01B11/06
Filed: 1983-12-21
Abstract: The production on transparent substrates of multiple-coating systems is measured by continuously determining the transmission and/ or reflection of highly refractive and slightly refractive coatings respectively applied to at least two glass test plates, as 5a. At least one of the coatings has a thickness of an integral multiple of ???/4 where ??? is the wavelength of the light 7, and at least one further coating has a thickness deviating from an integral multiple. Photo-receivers 12, 15 with monochrometers 11, 14 measure the proportion of the light reflected and/or transmitted by each test plate. Analysing circuit 24 recognises extreme values and data- processor 26 produces, via means 31, an adjustable control signal, prior to the application of the further coating, switching the monochrometer(s) to a wavelength at which the further coating produces an extreme value upon reaching its final thickness, and controls via output 28 a device for interrupting the coating process.   <IMAGE>

Patent GB-2143617-A (GB)
Title: Mechanical coupling which damps torsional vibrations
Inventor: MOSER PETER
IPC: F16H57/00
Filed: 1984-07-20
Abstract: The coupling has at least two weights (12), each of whose centre of gravity is at a distance from the axis (20) of the two main shafts (2, 5) serving as input and output. The weights are rotatably mounted in bearings (7, 8) which are rigidly connected to one of the main shafts (2, 5). Disposed between the other main shaft (2, 5) and the weights (12, 13) are transmission means (17, 18) tending to rotate the weights (12, 13) in relation to a zero position which the weights take up when the main shafts (2, 5) are running off-load and in synchronism with one another. The coupling has a torsional resistance which decreases with increasing load - i.e., the coupling is a mechanical coupling which has a very soft characteristic on full load. Also, the coupling helps to obviate the transmission of torsional vibrations from one of the main shafts (2, 5)- as a rule, the input shaft (2) - to the other main shaft - as a rule, the output shaft (5). <IMAGE>
