Patent GB-2034038-A (GB)
Title: Vibrating Wire Instrument System
IPC: G01F1/36
Filed: 1979-10-10
Abstract: In an instrument system including an electronic transmitter 12 for a vibrating-wire differential- pressure sensor 10 at a field location connected by a two-wire line 14 to a control room, the transmitter includes an oscillator 38 to vibrate the wire at its resonant frequency, and apply to the two-wire line 14 a corresponding alternating voltage signal. The control room equipment converts the frequency of this signal to an analog voltage measurement signal, with adjustable zero and span and linearization with respect to the input differential pressure. The two-wire line 14 carries a direct-current component the average value of which is automatically adjusted at the control room to match the scaled and linearized analog measurement signal. This d.c. current passes through a meter 20 at the transmitter to provide field service personnel with a visual indication of the value of the scaled and linearized measurement signal, and also powers the oscillator 38. <IMAGE>

Title: Selfoscillating inverter
IPC: H05B41/392
Filed: 1979-12-21
Abstract: In a self oscillating push pull inverter, the switching on and off of the transistors is precisely controlled to minimize power losses due to common-mode conduction or due to transient conditions that occur in the process of turning a transistor on or off. Two current feed-back transformers (29, 33) are employed in the transistor base drives; one being saturable (29) for providing a positive feed-back, and the other being non-saturable (33) for providing a subtractive feed-back to ensure rapid transistor turn off. <IMAGE>

Title: Rapid Curing of Epoxy Resin Coating Compositions by Combination of Photoinitiation and Controlled Heat
IPC: C08J3/24
Filed: 1980-03-13
Abstract: A method for the high speed coating of various substrates utilizes an epoxy resin composition containing a radiation-sensitive catalyst precursor which will decompose upon exposure to electromagnetic radiation to provide a Lewis acid effective to induce cationic polymerization of the epoxy composition. The formulation does not require any special epoxy monomeric materials or accelerators and is stable until so exposed. Subsequent to applying the formulation to the substrate, the coating is exposed to electromagnetic radiation and a controlled temperature of 50-90 DEG C. is maintained in the coating for a limited period of time to effect polymerization of the formulation to a tack free surface condition within a period of less than 30 seconds. Maintenance at the elevated temperature following initiation of irradiation may be for a period of as little as 0.5 second.

Title: Pressure die casting
IPC: B29C45/76
Filed: 1980-05-28
Abstract: In a pressure die casting machine the high pressure forces for the afterpressure phase are produced by means of a pressure multiplier (5, 6). The working pressure provided in chamber (4) by the multiplier piston (6) is controlled by the pressure in the annular counter pressure chamber (8) of the multiplier cylinder (5). The pressure in the counter pressure chamber (8) is adjusted by a pressure limiting valve (17) whose response threshold is determined by a control pressure storage device (26). In order to ensure a rapid build-up of afterpressure without overshoot or over-control at least the control pressure storage device (26) in the circuit arrangement (17, 19, 21, 25, 26, 33) precontrolling the pressure limiting valve (17) is constructed to be elastically deformable so that the circuit arrangement reacts to pressure fluctuations on attainment of the response threshold by the pressure in the counterpressure chamber (8) with an elastic closing force whose characteristic as a function of the valve travel is non- linear. <IMAGE>

Title: Power supply arrangement for electronic watches and similar portable apparatus
IPC: G04G19/02
Filed: 1981-03-05
Abstract: A power supply arrangement in an electronic timepiece Fig. 1, includes a thermo-electric generator TG which charges a buffer accumulator ACC via a chopper circuit comprising TR5, TR6 and a transformer formed by primary windings PW1, PW2 and the drive winding MW of the timepiece stepping motor which also functions as the transformer secondary. The AC voltage induced in the secondary MW is full-wave rectified by TR7 to TR10. A comparator COMP is activated periodically and controls a flip-flop FF to block the rectifier and chopper transistors and prevent possible discharge of the accumulator ACC via the rectifier if the thermo-electric voltage is too small. The whole of the drive energy for the watch is then provided by the accumulator. The motor drive current is fed via TR1 to TR4 which are controlled by outputs from a decoder DEC. <IMAGE>

Patent GB-2099794-A (GB)
Title: Gable topped cartons
IPC: B65D5/40
Filed: 1982-04-23
Abstract: A gable topped carton, for example for liquids comprises outer roof panels (10 and 12) connected to side walls (2 and 4), and gable panels (20 and 22) connected to front and rear walls (6 and 8). The gable panels (20 and 22) are connected to the outer roof panels by inner roof panels (24 and 26). The gable panels (20 and 22) meet the inner roof panels (24 and 26) along gable creases (25) which are not straight. In the illustrated embodiment, the gable creases (25) are arcuate. This avoides stresses in the carton material and provides easier opening of the carton. The inner roof panels (24) terminate in inner seal lips (30). The top edges of the inner seal lips (30) are shaped to reduce the efficiency of the seal in this area, again so as to provide easier opening of the carton. The outer roof panels (10 and 12) and the gable panels (20 and 22) meet the adjacent walls (2, 4, 6, and 8) along creases (9 and 19). The central portions of the creases (9 and 19) are coplanar, but the end portions (9A and 19A) deviate from the central portions to reduce bunching of the material at the corners of the carton.

Title: Repairing mains
Inventor: WILSON FRANCIS DONALD
IPC: E21B7/20
Filed: 1982-06-21
Abstract: In a typical example of the invention, the existing duct is a steel gas main which is to be replaced by a new plastics main. A mole is moved up the internal bore of the existing main and cutters with which the mole is provided engage the internal wall of the steel main and longitudinally slit the main at two diametrically opposite points thereon so that the main forms two semi-circular halves. The mole has a cylindrical body rearwardly of the cutters to which a new plastics replacement main is attached so that as the mole moves along the existing main it tows the new main into position within the existing main. The diameter of the mole body is such that it causes the two halves of the slit main to be moved radially outwardly to provide sufficient clearance for the new plastics main to be moved through the existing main. The internal diameter of the new main is equal to that of the existing main.
