Abstract: 1,029,797. Heating by circulating liquid. BRITISH BELTING & ASBESTOS Ltd. Sept. 7, 1964 [Sept. 13, 1963], No. 36156/63. Heading F4U. [Also in Divisions B5 and F1] In a portable heat-generating unit for use in the vulcanizing of belt joints in areas prone to fire and explosions, a liquid is frictionally heated by its passage through a restricted orifice and circulated to a pair of platens between which the belt joining is conducted. The main body of the apparatus consists of a flame-proof motor 1 driving a boiler feed pump 2 which has inlet and outlet pipes 5, 6 connecting it to a liquid chamber 4. A vertical pipe 7 is housed within the liquid chamber 4 extending from the inlet pipe 6 and has a fixed orifice 9 and an adjustable relief valve 8. The temperature of the liquid i.e. water or a water ethylene-glycol solution is raised by re-circulating the liquid through the fixed orifice 9, the liquid which may be at boiling temperature or at a thermostatically controlled temperature being circulated by a pump 10, delivery pipe 4A and return pipe 4B to the platens 16, 18 which transmit heat to the bell ends during the splicing process. The temperature of the circulating liquid may be controlled by means of the adjustable relief valve 8 and a liquid flow control valve positioned in the inlet pipe 5 to the pump 2. Prior to splicing, the belt ends may be dried in a current of hot air from a blower 12, Fig. 2 (not shown), which draws air either through a jacket around the chamber 4 or through tubes extending through the chamber; the jacket and tubes being packed with knitted copper wire. In a further embodiment, Figs. 7, 8 (not shown), a rotating rotor 21, whose vanes are shaped and perforated raise the temperature of the liquid and in addition may act as a rotary pump, thus replacing the main liquid pump.

Abstract: 963,395. Dicing and slicing vegetables and the like. FEATURE PRODUCTS Inc. Oct. 21, 1960 [Oct. 21, 1959; June 6, 1960], No. 36275/60. Heading A4C. A variable cut dicer-slicer comprising two juxtaposed cutting elements each having a plurality of parallel pre-stressed, e.g. stainless clock spring steel, blades of substantially uniform cross-section one cutting element being rotatable relative to the other. As shown, the foodstuff is pushed through the cutting elements by a head portion mounted on guides 22 sliding between rails 31 mounted in a base, movement being limited by pins 25 and 26 in the base which engage grooves 24 and 28 respectively in the guides. Coil springs 29 in grooves 28 bias portion 19 upwardly. Carried on a shoulder 38 on the base are a lower ring 16 located by lugs 39 and slots 40 and an upper ring 15 with a slip ring rib 37 on its lower surface sliding on ring 16 and ribs 23 on its upper surface. A spring loaded ball engages recesses 45 in the periphery of ring 15 to hold it in various positions relative to ring 16. Rings 15 and 16 each have a series of slots 49 to receive the convolutions of continuous blades 50 whose deformed ends 56 are held by metal wedges 55 in slots 54. Alternatively one, two or three separate blades may be used in each ring. Projections 59 on portion 19 have edges parallel to the blades in their various positions and push the food through the cutters. Damage to projections 59 due to incorrect positioning of ring 15 is prevented since the head 19 can only complete its stroke if a projection 18 on ring 15 is aligned with one of a series of pockets 17 on portion 19. If a potato is pushed through the cutter assembly with the blades parallel Fig. 10 and then turned through 90 degrees and passed through the cutter assembly with the blades perpendicular, Fig. 9, a completely diced potato is produced. In a modification, Fig. 17, the cutter rings may be provided on a movable portion carried by a single guide sliding in a post 84, forming part of the base on which the food stuff is placed. In a further modification, the base may have an opening 117 to accommodate dishes which receive the cut food stuffs, the solid head 119 being carried on guides 122 sliding in the base. A locking assembly 130 to hold the head 119 in lowered position comprises a handle 131 having an interior shaft portion 132 with a roughened tapered face 133 which engages on notch 134 in one of the guides 122.

A regeneration circuit 18 is responsive to the output from the detection circuit 16 to reproduce at terminals 19, 20 the binary values of the bits represented by the phase of the primary vector component. These reproduced values are also applied to a remodulation circuit 21 which modulates the reference carrier to produce an output signal having a phase with respect to the reference carrier equal to that between the primary vector component and the first carrier. A phase comparator 22 compares the phase of the modulated reference carrier with the input signal and controls the VCO 17 in a sense to reduce the phase difference to zero. The modulated reference carrier is also applied to a demodulative circuit 25, 26 which, by a vector subtraction operation, provides at terminals 27, 28 the binary values of the bits represented by the phase of the secondary vector component. An embodiment for demodulating vectors resulting from different combinations of primary, secondary and tertiary vector components is described with reference to Fig. 6 (not shown), whilst other embodiments utilizing reverse modulation arrangement are described with reference to Figs. 10 and 14 (not shown.

Abstract: 805,926. Electric tests. COMPAGNIE FRANCAISE THOMSON-HOUSTON. Dec. 30, 1955 [Jan. 7, 1955], No. 37449/55. Class 37. The strength of a magnetic field is measured by means of a transistor which is positioned in the field so that current carriers injected by the emitter are deflected away from the collector. The reduction in collector current is then an indication of field strength. In the particular example described, the transistor is of N-type germanium the emitter and collector either forming point contacts or being connected to p-n junctions formed by local contamination. The collector current may be observed on a milliammeter or compared by means of a galvanometer with a voltage tapped across a potentiometer. In the absence of a magnetic field the galvanometer current is regulated to zero by means of the potentiometer. When the field is applied the meter deflects and may be calibrated in terms of field strength. The D.C. supply to either the emitter or collector may be replaced by an A.C. one. An arrangement is described with reference to Fig. 3, wherein the collector is in two parts 41, 4<SP>11</SP>, and the magnetic field is arranged to vary the current distribution between them.

The relay PR is a bi-stable polarized relay which is initially operated to one position by the charging current taken by the capacitor C1 through a diode D1 and the relay coil. At the same time capacitors C2, C3 in the delay device V are charged to such potentials that a programmable unijunction transistor T2 is non conducting. Should the supply fail, the capacitor C3 discharges through a resistor R4, discharge of the capacitors C1 and C2, at this time, being prevented by diodes D1, D2. When the potential across the capacitor C3 falls below that across the capacitor C2, the transistor T2 conducts and triggers the thyristor T1 into conduction. The capacitor C1 discharges through the relay coil and the thyristor, the relay PR being operated to its other stable position and providing a control signal or effecting a changeover to another source.

Abstract: 971,526. Seaming non-metallic sheet materials. IMPERIAL CHEMICAL INDUSTRIES Ltd. Sept. 27, 1963 [Oct. 4, 1962; Oct. 5, 1962], Nos. 37646/62 and 37740/62. Heading B5K. A method of welding together adjacent members of a polymer of vinyl chloride comprises heating the adjacent edges of the members to the thermoplastic state and inserting into the gap therebetween a strip of soft plasticized vinyl chloride polymer having a softness of at least 20 and heating the strip so that at least its surface attains the thermoplastic state. The softness is measured as defined in B.S. No. 2782 Method 397A. If the gap between the members is not more than 25 times the product of the coefficient of linear expansion of the material of the members and the arithmetical mean of the distances from the gap to the nearest gaps on either side thereof the softness of the strip insert must be greater than 40. The strip may be preheated before being inserted into the gap and means may be provided to move continuously along the gap heating the edges of the material while continuously thereafter offering up the preheated strip into the gap. A directed hot air blast may be used to heat the strip and edges. The method is particularly applicable to joining adjacent sheets of P.V.C. fixed to walls or floors by an adhesive as a cladding for the surface; the resilient weld provides a flush surface while accommodating expansion of the sheets.
