Patent GB-1567569-A (GB)
Title: Error correction
IPC: G01D18/00
Filed: 1977-02-01
Abstract: In various types of equipment as, for example, in a two-beam spectral photometer, an error, which is a function of the independent variable of the equipment, must be corrected. In the equipment (11), the independent variable is sampled step by step between a lower and an upper limit. To correct the error, the device has a memory (21a, 21b) in which correction values are stored in the form of incremental change values for in each case one incremental section of the independent variable. Furthermore, a position indicator is stored which differs from the correction values and can thus be identified. The position indicator is moved in such a manner that it always adjoins the correction value for the current section of the independent variable. The error correction is read out at the position of the position indicator. In the memory, which is constructed as shift register, the correction data and the position indicator are circulated and the correction values are always read out at a particular point, the position indicator specifying the stored correction data which are used for the respective error correction. <IMAGE>

Abstract: 542,829. Automatic circuit-breakers. DAVIDSON, G. W., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. March 26, 1941, No. 4075. [Class 38 (v)] An arrangement for producing tripping of a circuit-breaker 3 if its speed of closure is below a given value, comprises a shaft 1 which is rotated clockwise to closed position and carries a cam disc 10 with a recess 11. During closure, the recess moves from the dotted position 18 to the position shown, and if the speed of closure is too low, a projection 14 on an inertia-lever 12 slips down the radial leading face 19 of the recess and a part 17 on the lever engages a trip latch 5 to produce tripping before the tapered near edge 20 of the recess is engaged by the projection 14. The Specification refers also to a shaft rotated by reason of the closure of the breaker.

Abstract: 607,750. Decompressor mechanisms. COVENTRY CLIMAX ENGINES, Ltd., and HATHAWAY, L. Feb. 11, 1946, No. 4223. [Class 7 (v)] A compression - ignition engine has a decompressor shaft rotatably mounted in bearings carried by the cylinder head so as to lie adjacent to the valve actuating ends of the exhaust valve rockers, cam members being provided on the shaft for engaging the rockers either simultaneously or selectively, and also means extending outside the valve cover for turning the shaft. In the form shown the cams are formed by threaded pins 23, 24, 25, 26, passing through the decompressor shaft 16. Each pin engages a pad 32 on its corresponding rocker, such as 29, Fig. 2, and keeps the exhaust valve 13 open. Fig. 1 shows the pins 23, 24, set in alignment and at an angle to the other aligned pins 25, 26; this arrangement enables the valves 12, 13, to be kept open while the valves 14, 15 are closed, or vice versa, and a further adjustment of the shaft enables all four valves to be kept open at the same time. The shaft 16 is turned by means of the lever 40 external to the cover 33, and connected to the shaft through the short shaft 35, arm 37, pin 38, and arm 39. Means are preferably provided for retaining the shaft in any desired operative position; these consist of a spring actuated ball adapted to engage recesses in a collar carried by the shaft.

Title: Supply circuit for a television receiver
IPC: H04N3/185
Filed: 1975-02-05
Abstract: 1502362 Converting circuits for television receivers INDESIT INDUSTRIA ELETTRODOMESTICA ITALIANA SpA 5 Feb 1975 [6 Feb 1974] 4836/75 Heading H2F A supply circuit for a TV receiver comprises a rectifier 3, smoothing capacitor 7 and a chopper 6 controlled by fly-back pulses from the EHT transformer 10. The transformer 10 is arranged (e.g. by third harmonic tuning) so that the ratio of average voltage across the chopper 6 to the crest value is greater than 0À85. This arrangement reduces the dissipation in the chopper 6. As described, the chopper 6 is driven by fly-back pulses induced in winding 9 of the EHT transformer 10 after differentiating at 12. The output from chopper 6 is passed via resistor 8 and diode 22 (which protects transistor 6 against over voltage) to the primary 27 of the EHT transformer 10 and then to a smoothing capacitor 37 which provides a voltage at 36 which is used for other stages The flyback pulses in winding 9 are also peak rectified at 18 so as to feed D.C. to the base of transistor 11 which modifies the action of chopper 6 so as to stabilize the output against variation in the A.C. supply. A feedback resistor 23 gives further improvement in the relationship between beam current and EHT voltage. The Specification shows the reduction in dissipation in transistor 6 achieved by tuning transformer 10 to the third harmonic rather than the fifth harmonic in known arrangements.

Title: Improvements in or relating to the manufacture of reinforced synthetic resin articles
Inventor: JOHN WILLIAM HAYDN THOMAS
IPC: B29C70/42
Filed: 1956-02-17
Abstract: A moulded reinforced synthetic resin article of complex shape is produced by a method comprising first impregnating a knitted fabric, which is extensible under load, with a heat-hardenable synthetic resin e.g. a phenolformaldehyde resin in admixture with a filler, e.g. chalk, partially curing the heat-hardenable synthetic resin impregnated in the knitted fabric, and thereafter subjecting the knitted fabric so treated to a moulding operation to produce the complex shape, in which operation the curing of the synthetic resin is completed.  A complex shape is one which requires a deep draw of the reinforcement during the closing of the mould, i.e. an amount of draw which is beyond the limit of extensibility of the commonly-employed substantially inextensible reinforcement fabrics. The knitted fabric may be of any organic or inorganic material or mixture of organic and inorganic materials, that is capable of being knitted into a fabric that is extensible under load, and can be bonded by the synthetic resin, e.g. glass, rayon or cotton.  The synthetic resin may be used in the form of a solution.  The impregnated and partially cured cloth may be cut into sheets and a number of plies, depending on the required thickness of the final object, placed over the female half of a matched mould.  The plies are held around the periphery of the mould cavity by means of a pressure plate or draw ring and the heated male half made to descend slowly, warming and extending the sheets at points of contact.  The mould is finally closed under pressure, and the sheets allowed to cure.  Alternatively, the sheets may be heated by infra-red lamps after they have been clamped over the female mould, so that the male half can be made to descend at a faster rate.
