Patent GB-729477-A (GB)
Abstract: 729,477. Thermo-responsive alternating current instruments. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Sept. 3, 1952 [Sept. 11, 1951], No. 22170/52. Class 37. In a thermo-responsive instrument 1, Fig. 1, having a heating resistor 3 producing a deflection of pointer 5 with variations of A.C. voltage E to be measured, the heating resistance 3 has a positive temperature coefficient and is energized by a voltage e developed across an inductance 23 which is in series with a capacitor 21 across E. As E increases the resistance R of heating resistor 3 increases so that the current I therein tends to decrease but as R increases e must increase to increase I and the I to E relationship is more linear and the I<SP>2</SP>R heating in 3 is higher and the instrument sensitivity thus also higher than would be the case if E was applied directly to the heating resistor 3. E is at constant frequency and the reactances of 21 and 23 may balance or the inductor 23 may be so designed that its inductance decreases with voltage to give different sensitivity over different voltage ranges. The pointer 5 may carry a contact 9 which meets a fixed contact 11 to operate a circuit interrupter 15 when E attains a selected value. In a second arrangement, Fig. 2, hot and cold bimetallic spiral springs 25, 27 are oppositely wound and disposed around a shaft 29 so that heat from resistor 3 produces rotation of shaft 29 and pointer 5A. The resister 3 is fed with voltage e from a potential transformer 23A whose open circuit reactance substantially balances the reactance of capacitor 21 but may decrease slightly as E increases to control sensitivity. A maximum demand pointer 33 is provided. In Fig. 2 the increase in I<SP>2</SP>R of heating resistor 3 at high values of E also compensates for the decrease in deflection constant of spring 25 with increase in temperature. An additional feature again in contrast to feeding the heating resistor 3 direct from E is that the maximum demand interval is less. The volt-ampere measuring instrument shown in Fig. 3 employs Fig. 2 at 35B for the voltage component except that the hot spring at 57 is directly heated by the voltage e and like resistor 3 has a positive temperature coefficient. The ampere component at 35A comprises a hot spring 39 heated by a resistor 47 fed from a current transformer 49. The instrument shaft 41 is rotated by the current component 35A and also via suitably designed linkage 65 by the voltage component 35B so that pointer 41B indicates VA or KVA prevailing in lines L1, L2. The pointer 41B may drive a maximum demand pointer 41D. The springs 55, 57 may be identical in construction in view of the higher sensitivity at high values of E across L1, L2.

Patent GB-2028216-A (GB)
Title: Backflow seal for screw injection moulding machines
IPC: B29C45/52
Filed: 1979-08-08
Abstract: Backflow seal of injection moulding machine comprises a mushroom- shaped body 15 which is sealingly guided with its shaft in an axial bore 14 provided on the end face of the screw head 10 and is movable between two stop positions. In the front stop position, the head 17 of the seal releases passages 11 for the plastics material in the screw head 10; in the rear stop position these passages are closed by the head 17 of the seal. Since the mushroom-shaped seal is freely slidable in the axial bore, it is automatically kept in the open position, without a throttling action which would restrict flow, by means of the plastic material which is conveyed forwards by the screw 2. On the other hand, the "breathing" of the plastic mass in front of the screw 2, which occurs at the end of the plasticising stage, suffices to press the seal into the closed position. <IMAGE>

Patent GB-2077421-A (GB)
Title: Displacement sensing
IPC: G01B11/14
Filed: 1980-05-31
Abstract: A sensor system senses displacement x of a target surface 13 from a datum plane I. It includes bifurcated fibre-optic 7, comprising light-emitter fibres 5 and light-receiver fibres 6, used with a lens 11 to project white light from lamp 2 onto surface 13 and conduct light reflected from it to photo-detector means whose output is a function of the displacement x. To overcome problems due to different target reflectivities and concerning determining the sense of the displacement x two sensor channels are used, each sensing light at different wavelengths or wavelength bands with substantial spectral separation. Lens 11 images the end surface of the fibres 5 on surface 13 and forms a secondary image on this end surface using the light reflected from the target, the datum plane being the average primary image plane for the two wavelengths. A photodiode PR senses red light and photodiode PB senses blue light, beam splitter 19 and filters FR and FB being used to separate the red and blue light components of the light from fibres 6. After balancing at 33, the outputs of PR and PB are combined in either a differential or a proportional amplifier 35 to produce a system output signal E(x) whose magnitude is dependent on the relative magnitudes of the light fluxes in the two channels, and is hence also a function target displacement from datum plane I. <IMAGE>

Patent GB-2062909-A (GB)
Title: Analogue-display timepiece
IPC: G04C3/14
Filed: 1980-10-09
Abstract: Instead of conventional hands, an hour disc and a minute disc are provided. The hands are represented by markers vaporized upon the undersides of the discs. The discs are pivoted on an arbor anchored in the watch glass. This arbor is hollow, and inserted in the free end thereof is a rivet-shaped retaining part which keeps the discs from slipping off the arbor. Each disc is toothed at its circumference. The teeth of the minute disc engage a gear wheel having a pinion which meshes with the teeth of the hour disc. This wheel and pinion are mounted on an arbor, one end of which is anchored in the watch glass. A retaining ring prevents the wheel from becoming detached from the arbor. This gear wheel likewise engages a pinion of another gear wheel mounted on an arbor. One end of this arbor is also anchored in the watch glass. A pinion of a stepping motor meshes with the teeth of the further gear wheel. The yoke of the stepping motor is rigidly connected to the watch glass by means of bolts which likewise have one end anchored in the watch glass. A shaft bearing the pinion and the rotor of the stepping motor is pivoted at one end in a recess in the watch glass. Because all the parts necessary for driving the discs, as well as the discs themselves, are either fixed to the watch glass or pivoted about arbors anchored in the watch glass, plates can be dispensed with, so that manufacture of the timepiece is considerably simplified.
