Title: Electrical connector
IPC: H01R24/86
Filed: 1973-11-21
Abstract: 1448001 Two-part couplings G & H TECHNOLOGY Inc 21 Nov 1973 [24 Jan 1973] 54088/73 Heading H2E In a two-part connector one part has contact means movable axially of the connector towards the contacts of the other part under the action of a resilient biasing means, the connecter comprising a rotatable member for locking the two parts together, the biasing means also serving to restrain movement of the contact means when the parts are not locked together. The plug 18 comprises contacts 74 mounted in insulators 70, 72 within a shell 55 on which is screw threadedly 94 mounted a sleeve 92 having a flanged 98 forward end which lock-engages behind shoulders 102 on the socket shell 20; the plug and socket, as so far described and their polarizing, screening, sealing and mounting means are substantially as described in Specification 1,447,497. The screw threads have wider roots than crests so that there is "lost-motion" between the shell 55 and sleeve 92. A frustoconical spring washer 110 acts between the ends of the shell 55 and sleeve 92. In use, rotation of the sleeve 92 brings the flange 98 into locking engagement with the shoulders 102 and moves the shell 55 with the contacts 74 and insulators 70, 72 axially of and relative to the sleeve and the socket, the shell taking with it the inner edge 114 of the spring washer 110; at a point during the movement when the washer is generally in one plane its resilience changes direction to act on the shell in the direction the shell is moving and take up the lost motion and "snap" the contacts 74 into engagement with the contacts of the socket.

A volatile substance, e.g. a monomer and or solvent, is removed from a polymer composition, or other mixture of viscous material and volatile substance, by injecting the mixture through pipe 1 and orifices 5 to form strands 6 in a vessel 3, maintained under sub-atmospheric pressure e.g. 50-100 Hg. absolute, wherein the strands impact the peaked roof 21 of a hollow elongated heater 20 and the material flows, in the form of a film, down the hot walls 22 and 23. Volatile substance is vaporized from the strands with foaming. Residual volatile substance is vaporized from the film. Voltatile substances are withdrawn from vessel 3 through opening 15; and the devolatilized material flows out through outlet 16. The mixture is heated under pressure before it is injected through orifices 5 into vessel 3. The orifices 5 have a diameter of about 3 mm. Conduits are provided for circulating heating fluid through the heater 20, and through the jacket 17 of vessel 3. The strand-former is also provided with a heating- jacket 7. Examples are given which relate to the removal of styrene and solvent (ethyl benzene or toluene) from a reaction solution obtained by bulk polymerization of styrene. The polystyrene product contains less than 0.5 wt. % of volatile substance. Volatile substances can also be removed by this process from acrylonitrile-styrene copolymerized resins, and from acrylonitrile-butadiene-styrene copolymerized resins.

Abstract: 1279058 Electronic watches DAINI SEIKOSHA K K 24 Nov 1970 [28 Jan 1970] 55910/70 Heading G3T In order to minimize the power consumption of a battery powered timepiece e.g. an electronic watch, wherein a quartz crystal controlled oscillator provides timing pulses which are converted to lower frequency drive pulses by a frequency divider followed by an amplifier, there is provided a pulse width converter which reduces the width and hence the area of the drive pulses before their amplification and application to an electro-mechanical transducer. The transducer is coupled via gears to hands. The oscillator circuit is illustrated in Fig. 2 (not shown) and includes a capacitor connected to compensate for drift in frequency of the crystal due to temperature changes which might occur above 50C. ambience. A variable capacitor is also provided to permit regulation of the oscillator output frequency to correct error in timekeeping. The frequency divider is illustrated in Fig. 3 (not shown) and comprises two astable multivibrators in cascade, performing a quarter frequency division, followed by ten flip-flop circuits in cascade each dividing by two. When the oscillator frequency is 16,384 Hz the divider output will be 1 Hz. The pulse width converter Fig. 4 is a monostable multi-vibrator and receives the divider output at 41 in and produces output pulses at 41 out, the width of which are determined by the time constant of R 11 C 11 . The reduced width pulses are amplified by a circuit Fig. 6 (not shown) comprising transistors connected as a Darlington pair. When a drive pulse is received by coils La Lb of the transducer Fig. 7, a permanent magnet rotor 66 is caused to rotate anti-clockwise sufficient for a pallet jewel 67b carried by a lever 68, which is fixed to and rotates with rotor 66, to rotate a wheel 161 anti-clockwise by one half tooth pitch before disengagement. At theend of a drive pulse the magnet rotor is returned to its equilibrium position (as shown) by a spring (not shown) whereupon pallet jewel 67a rotates the wheel 161 anti-clockwise another half tooth pitch.

Abstract: 1365498 Cultivators C VAN DER LELY NV 15 Dec 1971 [21 Dec 1970] 58296/71 Heading A1B A cultivator comprising a main frame beam 1 with a row of soil working members 3, each of which is rotatable about a corresponding upright shaft 2, is provided at its forward edge with a deflector 12 consisting of a rigid beam 13 of L-shaped cross-section, with a cover plate 14 to prevent stones from lodging between the two limbs. Beam 13 is connected to horizontal pivots 16, located forward of deflector 12, by supports 15 at its opposite ends. The height of deflector 12 with respect to frame beam 1 can be altered by varying the setting of support 18, attached to pivot 16, in vertical guides 19 at opposite ends of frame 1 and of pivot (27) attached to bracket (26) on support (25) at the midpoint of the frame 1. Deflector 12 is held resiliently in position against stops 24 by strong springs 22 extending vertically between pins 21A in supports 18, and pins 23 at its opposite ends. Thus any stone entering between deflector 12 and tine supports 5 forces deflector 12 to turn downwardly and forwardly about the axis of pivots 16 and 27 against springs 22 which, when the stone has fallen or been pushed clear, restore deflector 12 to its original position. The lowermost edge of deflector 12 is between 0 and 6 cms. below that of the tine supports 5 and between 1 and 2cms from the foremost position of the tines 6. A rotary compressing roller 8 and shield plates 11 are provided as described in Specification 1277679, and the soil working members are constructed and arranged as described in that specification. In another embodiment, Fig. 7 (not shown), an alternative deflector (30) mounted and generally constructed as is deflector 12, consists of a series of neighbouring arcuately curved portions (31), the centres of curvature of which coincide with the axes of the associated soil working members 3. Reference has been directed by the comptroller to Specifications 1226679, 1226680 and 1277679.

Abstract: 1434777 Cathode-ray tube displays SIEMENS AG 18 Dec 1973 [10 Jan 1973] 58612/73 Heading H4T In a cathode-ray tube display system in which a data source, e.g. a data processor or a keyboard, supplies character data to an image repetition store supplying an output to a character generator from which, via a digitalto-analogue converter, beam deflection signals to trace the characters are supplied to the tube, the data source is additionally operable to supply tabular data which is indicative of the position on the tube screen at which a tabulator mark is to be displayed, the character generator then producing the signals necessary to trace such mark at the required position. As shown in Fig. 2, the screen of the tube is deemed to be divided into a plurality of zones arranged in rows Z1 to Z81 and in columns S1 to S16 each zone corresponding to a storage location in the image repetition store. In operation, when character date is to be displayed, a "printmark" S.M. is entered into the storage location corresponding to the position at which a character is to be displayed, the character data is stored in the same location and the "print mark" is automatically shifted (to the right) by one zone. Thus each character is displayed in any zone in which the print mark was previously displayed. For the display of tabular marks the "print mark" is set up in the required position and the tabulator mark HT is displayed as in the case of the display of characters, when a "tabulator set" key is operated. The tabulator marks may be displayed in any zone in rows Z1, Z2 or Z16, the marks moving up or down the screen in accordance with a "rolling-page" type display, i.e. progressively down from row Z1 to row Z16 or progressively up from row Z16 to row Z1. When the marks are initially displayed in row Z1 or reach this row as a result of the "rolling- page" operation, they are displayed permanently, i.e. for the duration of any one operation. When rapid display of characters between tabular marks is required operation of a "tabulator-jump" key causes the display to process to and then stop at a tabulator mark. Other key facilities provided include "erase tabulator mark", "erase tabulator row" and "erase image" (i.e. the characters) without erasure of the tabulator marks. Instead of displaying the tabulator mark in separate zones it may be displayed in the same zone as the character (Fig. 5). The whole operation is described with reference to logic circuitry, Figs. 1, 3, 4, 6 and 7 (none shown).

Abstract: 1368709 Crystallizing from solutions TORAY INDUSTRIES Inc 20 Dec 1972 [28 Dec 1971] 58965/72 Heading BIG In a continuous crystallization process for recovering crystals from a solution using an elongated vessel with an inlet and outlet at opposite ends, the hot solution is fed into the vessel and passes through a cooling temperature gradient which is formed by cooling the solution in the vessel adjacent to the outlet to a temperature below the saturation temperature of the solution and mixing the contents of the vessel so that the temperature decreases towards the outlet whereby the solution crystallizes in the region of the inlet and the size of the crystals increase towards the outlet from which they are recovered. The cooling of the solution adjacent to the outlet is preferably effected by withdrawing part of the solution cooling it by passing it through a heat exchanger and returning it to the rest of the solution in the vessel. The mixing may be effected by rotation of impellers preferably in a plane extending transversely to the direction of movement of the solution through the vessel. As shown in the figure, into cylindrical vessel 1, solution is charged through line 3 into a body of liquid filling space 4 and withdrawn from the lower end of the vessel 5, through line 6 as a crystal slurry. The body of liquid is divided roughly into two zones, one being the crystalline zone A in which the temperature decreases towards the outlet and a zone B in which the temperature is maintained below the saturation temperature of the solution. The removal of heat from zone B may be by cooling jacket 17 and/or heat exchanger 7 and pump 9. The mixing of the solution may be effected by agitator 15 and impellers 16. The pressure in the vessel may be maintained constant by connecting a supply of gas 13 to the vessel via line 14. The apparatus and process is especially used for making crystals of terephthalic or isophthalic acid.
