Abstract: 850,666. Belt-fastening appliances. HAYDEN-NILOS Ltd. Sept. 12, 1958 [Jan. 15, 1958], No. 1389/58. Class 80 (1). In a machine for clinching wire hook fasteners into the end of a belt, a jaw unit 20 is guidedalong two transverse bars, such as the rack bar 18 and comb bar 19, extending between side frames 1, the jaw levers 24, 25, Fig. 3, being connected by toggle links 33, 34 to a slider 36 coupled by upper and lower links 38, 41 to short level arms 40, 43 which are moved by upstanding handles 49, 50 in opposite directions about the axis of the rack bar 18. The links 38, 41 are curved to clear the bar 18. The handles 49, 50 are detachably mounted on stub ends and are anchored by slack chains 59. The side frames, Fig. 2 (not shown), are shaped to form skids and carry means for clamping the belt as in Specification 850,665. The frames are suitably recessed so that wide belts may be accommodated, in which case hook pressing may commence from either edge. The jaw cheeks, Fig. 3, may be replaceable to suit the hooks 30, the cheek 26 being adjustable for belt thickness by a screw 27. The slider 36, Fig. 1, has a pro, jection 51 on which a spring-loaded pawl 53 is pivoted, the pawl engaging the rack bar 18 to traverse the jaw unit at each jaw movement. Two stops are provided to limit the angular movement of the pawl. The tubular comb bar 19 is replaceably secured in plates on the side frames. A hook-supporting thrust member 63, Fig. 7, shaped as shown, fits round the jaw unit and slides along a slot in the comb bar. A rod 66 retains the hooks in the comb bar, the rod having its outer end slightly bent so that it is held in position by jamming (Fig. 6, not shown). The jaw cheeks, Fig. 8 (not shown), have stepped surfaces so that as one hook is pressed in additional pressure is exerted on the two preceding hooks. The Specification also describes the modified jaw unit employed for inserting double hooks, as described in Specification 850,665.

Abstract: <PICT:0461772/III/1> <PICT:0461772/III/2> <PICT:0461772/III/3> <PICT:0461772/III/4> Physical or chemical treatment between one or more liquids and/or powdered solids e.g. mixing, emulsifying, washing, and chemical reactions, is carried out by admitting one of the phases to be treated to a surface of revolution rotating at high speed so that it forms a continuous layer over the said surface, and admitting another phase to a second surface of revolution, also rotating at high speed, so that the second phase is projected by centrifugal force in an atomized state from the edge of larger diameter of the second revolving surface into the thin layer formed on the first surface.  Fig. 1 shows diagrammatically a suitable apparatus in which one phase, is spread as a thin film over the inner surface of cone 1 and the second phase is projected into the first from the edge 6 of the lower rotating cone 5.  Fig. 2 shows a modification in which the lower surface is altered so that the mixture &c. formed is further treated by projection from the edge 4 of the upper cone on to the surface 13.  The phases may be introduced from hopper 8 and by suction from container 11, or in a modification, a double hopper may be used, the second phase being fed on to portion 5 of the lower surface.  Fig. 7 shows an arrangement for treating three phases.  One phase is fed by hopper 8 and flows down the inner surface of cone 1, and the second phase is projected into it from the edge 6 of the lower cone 5.  The mixture &c. thus produced is projected from edge 4 of cone 1 into the third phase flowing down the inner surface of cone 25.  The surfaces may be smooth or milled.  The treatment may be controlled by the rate of feed of the phases to the surfaces, by the relative velocities of the surfaces, and by their relative positions, diameter and shape.  The treatment may be carried out under pressure, or under a vacuum or in the presence of active or inert gases.  The final mixture or emulsion may be collected as shown in Fig. 6 by placing a stationary surface 23 or 24 opposite the last rotating surface.  The stationary surface may be plain, ribbed or perforated.

Patent GB-712618-A (GB)
Title: Process for refining petroleum hydrocarbon fractions
Inventor: WINDEBANK CHARLES SIDNEY
IPC: C10G29/02
Filed: 1951-01-25
Abstract: Petroleum fractions are treated at elevated temperature with sulphur or a sulphur compound which liberates sulphur at the temperature used, in the presence of a nitrogen-containing rubber vulcanization accelerator.  The sulphur reacts with olefins present giving a product of reduced tendency to gum.  If desired, this may be separated by distillation from the complex sulphur compounds formed. Where sulphur is present as such or as disulphides, e.g. in cracked stocks, further addition of sulphur may be unnecessary.  The vulcanization accelerators include nitrogen bases and their derivatives, condensation products of aldehydes with ammonia or amines, guanidines, especially aryl guanidines, and compounds containing sulphur, e.g. thioureas, dithiocarbamates, mercaptothiazoles, mercaptobenzthiazoles, and thiuram disulphides. Specific examples are zinc dimethyl (or dibutyl) dithiocarbamate, piperidine pentamethylene dithiocarbamate, and mercaptobenzthiazole. Temperature is generally 50-400, preferably 125-175 or 200-300 DEG C., using free or combined sulphur respectively.  The amount of accelerator is generally up to 10 per cent. by weight of the sulphur. In an example, a reformed naphtha is refluxed with 1 per cent. of sulphur and .01 per cent. of mercaptobenzthiazole at 165 DEG C. for 7 hours.  Specification 696,439, [Group IV (b)], is referred to.

Title: Improvements relating to self-balancing electrical measuring apparatus
Inventor: GALL DOUGLAS CRISP
IPC: G01R1/28
Filed: 1963-01-16
Abstract: 1,082,241. Electric selective signalling. H. TINSLEY & CO. Ltd. April 10, 1964 [Jan. 16, 1963], No. 1935/63. Heading G4H. A self-balancing electrical measuring apparatus comprises two digital systems of the type described in Specification 918,415, one of the systems determining rapidly the most significant digits and making corresponding adjustments to the other system which then determines the least significant digits. In Fig. 1 a voltage V to be measured is connected by a switch 28 to terminals 19 and 20 and balanced against the voltage across resistance 16, as described in Specification 918,415, by means of decade counters T1-T4 which control respective conductance arrays C1-C4 and corresponding indicators N1-N4 which indicate the four most significant digits. Switch units T1-T4 also control relay units R1-R4 which switch precision conductance arrays C<SP>1</SP>1-C<SP>1</SP>4 into the same condition as C1-C4. Resistance R16 is chosen so that at balance the fourth digit is too high by one digit. At balance, selector TB moves from position 6 to position 7 thereby causing switch 28 to apply the voltage V to the terminals 19<SP>1</SP> and 20<SP>1</SP> of the precision circuit. As the setting is too high the first error pulse from switch 21<SP>1</SP> is positive and passes through switch 102 to lead 103, the zero contact of switch 105 (which is controlled by decade counter T5), and through diode D1 to step stage T4 down one digit. The setting now being too low the next error pulse is negative and passes through D2 and inverter 107 to step stage T5 down from 0 to 9 and cause switch 105 to move to its 1-9 contact. Succeeding positive pulses pass through D3 to step T 5  down to its correct value, and when this is achieved the next negative pulse switches the switch 102 so that its output goes to lead 104 and adjusts the final stage S6 in a similar manner. If the voltage V should fall during the measurement, stages T5 and T6 attempt to secure a balance but if they both fall to zero before balancing a positive pulse passes through D5, inverter 110, and closed switch 105<SP>1</SP> to a relay 73 which causes the whole measurement process to start again. If the voltage V rises, a negative pulse on contacts 1-9 of switch 108 operates relay 73; if contact 0 of switch 108 is engaged the pulse steps the stage T6 to 9 and the next pulse will operate the relay. Switches T2C-T4C are closed only when their respective stages are at zero and allow the preceding stage to be stepped back one digit when a stage is stepped from zero to nine by a pulse from D1. The circuit shown can be turned into a bridge circuit for measuring resistance by connecting the unknown resistance across the moving contacts of switch 28 and connecting suitable fixed resistances between points C and D and between points C<SP>1</SP> and D<SP>1</SP>.
