Title: Apparatus for treatment of tubular knitted fabrics
Inventor: REDMAN FRANK ROBERT
IPC: D06C5/00
Filed: 1949-07-08
Abstract: 673,088. Finishing fabrics. REDMAN, F. R. July 8, 1949, No. 18142/49. Class 42 (i): Apparatus for treating tubular knitted fabric which has been elongated lengthwise and narrowed widthwise by processing subsequent to knitting of the fabric, has laterally spaced expansion elements over which the tubular fabric is passed and which internally expand the fabric widthwise and condense or shorten it lengthwise, and means for supplying the fabric to and removing it from the said elements so as to permit widthwise expansion of the fabric without subjecting it to appreciable lengthwise tension. As shown, moist elongated tubular knitted fabric 13 coming from wet processing is fed over a spreading device 34, which expands it widthwise to its original circumferential dimension, to a roller 14 against which it is spring-pressed by a roller 15 and which deposits it in relaxed condition on to the conveyer 20 of a drying and shrinking machine. Widthwise spreading is effected by wheels 44-53 on pivoted arms 40, 41, the inclination of which can be varied, according to the desired widthwise expansion, by adjusting a wheel 58 threaded on a rod 54 fixed to a support 35 to which arms 40, 41 are pivoted. Support 35 carries rollers 36-39 which support the whole device on feed rollers 11, 12. Rod 56 carries four rollers 62-65, and also a pair of rollers 67, 68 on resilient arms 66. Rollers 62-65 open the fabric, rollers 67, 68 spread it for upward passage over wheels 44-53, and wheels 44-53 effect the expansion in a series of progressive steps. Rollers 11, 12 are geared together, roller 12 is driven from a variable-speed motor, and roller 14 is driven from roller 12 by a variable-speed belt drive. Rollers 11, 12 are arranged to feed the fabric to the expanding wheels at a speed which is sufficiently greater than the peripheral speed of roller 14 to allow the widthwise expansion to take place substantially without longitudinal tension. In a modification, roller 15 is dispensed with, the fabric being pressed against the upper two pairs of expanding wheels by driven flanged rollers which serve to push the fabric from the spreading device on to roller 14.

Title: Improvements in or relating to registering or recording devices for weighing apparatus
IPC: G01G23/18
Filed: 1935-06-25
Abstract: 456,850. Weighing-apparatus. FITZPATRICK, H. D., 94, Hope Street, Glasgow.- (Maatschappij van Berkel's Patent Naamlooze Vennootschap ; 33, Boezemsingel, Rotterdam, Holland) June 25, 1935, No. 18144. [Class 143] Printed records, apparatus for giving.-A registering and recording device for weighing- apparatus comprises an auxiliary pointer-like member adapted to be driven in a circular path from a load - influenced element, such, for example, as the weight indicator, and locking means extending completely round the circular path so as to be capable of locking the auxiliary pointer at any point in its path when the indicator is in equilibrium and so that registering or recording of the weight can take place during changing of the load because the auxiliary member remains in recording or registering position when the weight indicator returns to zero on removal of the load. The indicator casing, as shown in rear elevation in the Figure, contains a printing rim 4 co-operating as described in Specification 421,022 with a printing device (not shown), and driven by an electric motor 5 whose circuit includes a switch 16. The rim carries an electromagnet 7 with a pawl 8 engaging a projection 9 on a loose arm 10 carrying a hunting contact 10a. The spindle of the weight indicator or pointer 1 has a one-way driving member 12 for actuating a flexible auxiliary pointer 2 carrying an electric contact 2<a>. An electromagnetic ring 11 energized through a switch 15 from the secondary of a transformer 20 is arranged adjacent to the auxiliary pointer 2. When a load is placed on the weighing-apparatus, the weight indicator 1 moves round the dial in an anticlockwise direction as seen in the Figure, the driving member 12 pushing the auxiliary pointer 2 therewith. When equilibrium is established the switch 15 is closed and the electromagnetic ring 11 attracts and holds the auxiliary pointer 2. The load may now be removed from the apparatus, the auxiliary pointer 2 remaining in locked position. The motor switch 16 is now closed and the printing rim rotates, carrying with it the arm 10 by reason of the engagement of the pawl 8 with the projection 9. When the hunting contact 10<a> engages the contact 2<a>, the printing rim 4 is locked and a circuit through the conductors 21 actuates the printing means in the manner described in Specification 421,022. Also, the electromagnet 7 releases the pawl 8 and the arm 10 is returned to zero by a suspended weight. On de-energization of the ring 11 a second suspended weight returns the auxiliary pointer 2 to zero position.

Title: Improvements in or relating to the production of tetrahedron-shaped packages
IPC: B29C65/00
Filed: 1955-06-23
Abstract: 769,888. Packaging. HERMORION, Ltd. June 23, 1955 [June 29, 1954], No. 18174/55. Class 94(1). A method of producing liquid-filled, tetrahedron-shaped packages comprises successively compressing and sealing a thermoplastic tube along narrow zones transverse to the axis of the tube and alternately in two mutually perpendicular directions while supplying liquid to the tube at such a rate that its level is always above the zone being sealed and applying external pressure to the walls of the packages during the compressing and sealing operations to force them to enclose a somewhat smaller volume than that which would automatically be obtained without such pressure due to the pressure of the packaged liquid and the elasticity of the tube. The walls of each package extending from one sealing zone are thus caused to assume a plane or concave instead of a convex contour, and when the package is opened by cutting-off or piercing one corner they expand to cause lowering of the level of liquid in the package and prevent leakage or overflow. The package may be marked with a line to indicate where it may be cut without danger of leakage. As shown, the packages are produced by a modification of the machine described in Specification 711,855 in which transverse seals 5 and 6 are formed by pairs of co-operating jaws 1 and 2 provided with inclined flanges 7 and carried by endless conveyers, the flanges being formed with projections 9 which cause the walls of the packages to assume a concave contour 10 instead of a convex contour 8 during the sealing operations.

Abstract: 835,245. Power-generating systems; turbines. SONNEFELD, G. June 13, 1956 [June 13, 1955], No. 18269/56. Classes 110 (3) and 122 (3). Relates to means for increasing the thermal efficiency of a steam cycle and consists in a steam power plant having a main steam cycle and an additional steam cycle superimposed thereon, the additional cycle having a maximum pressure less than that of the main cycle and a minimum pressure greater than that of the main cycle and the exhaust heat of the additional cycle being used to preheat, evaporate and superheat the main cycle condensate when it is at the maximum pressure of that cycle. In the arrangement shown in Fig. 3, main cycle condensate from condenser Ko is pumped by pump Fp through feed water heaters Ph1, where it is heated by bled steam from turbines TN and TV, preheated, evaporated and superheated in preheater Ph2, evaporator B and superheater S, respectively, by the exhaust steam from turbine T, further superheated in superheater SF by flue-gases in chamber H, expanded in turbine TA, reheated in superheater SR and finally expanded in turbines T and TN which provide the plant output. In the superimposed additional cycle steam discharged from the compressor K is superheated by flue gases at SR with the exhaust steam from turbine TA, expanded in turbine T and passes with loss of heat through superheater S, evaporator B and preheater Ph2 to the compressor K. The turbine TV is supplied with steam from the T-K circuit upstream of the compressor K. In the arrangement shown in Fig. 4 compressed air from an air compressor KL, driven by an air turbine TL1, is heated by flue gases in a heater SA, expanded in the turbine TL1 and further expanded in a separate air turbine TL2 coupled to the turbine TA. In a modification, Fig. 6 (not shown), a vaporizing drum and steam circulating pump are added so that the further cycle may be shut off, if desired, e.g. for overhauling components thereof, and the plant operated on a normal steam cycle. Temperature-entropy diagrams of the cycles are shown and described.
