Abstract: 875,941. Nuclear fusion reactors. UNITED STATES ATOMIC ENERGY COMMISSION. June 18, 1959 [Aug. 20, 1958], No. 20945/59. Class 39(4). A stellarator comprises means for establishing a helical magnetic surface within a portion of the stellarator tube and a circulariser for transforming the helical magnetic surface into a circular magnetic surface, the circulariser including a current loop near the end of the helical magnetic surface. The stellarator is preferably provided with four or six helical windings which preferably cover the whole length of the tube except the divertor and magnetic pumping sections. Fig. 4 shows one form of circulariser which may be provided at the ends of the windings, wherein each helical winding 120, 122 is bent to run at a right angle to the axis of the tube 10 for half the distance towards the adjacent winding, then runs parallel to the tube for a distance d/# (where d is the axial distance between adjacent windings), and is then connected to an adjacent winding to form an almost rectangular current loop. In another arrangement, Fig. 5, each winding 120, 122 is bent to double the tangent of the angle it makes with the axis for an axial length of d/2, and the windings are then joined together in pairs by wires running at a right angle to the axis of the tube 10. In a further arrangement, Fig. 6 (not shown), the windings are joined together in pairs twice at a distance apart d, the joins being by wires running at a right angle to the axis and each wire carrying half the current flowing through the winding. The end loop of the stellerator tube may include portions having a negative curvature (i.e. the centre of the curve of the tube axis is outside the stellerator loop) and, as shown in Fig. 7, parts 130 of negative curvature may alternate with parts 128 of positive curvature. The reversed curvature section increases the ratio of plasma pressure to magnetic field pressure. Specifications 844,291, 866,544 and 867,315 are referred to.

Title: Improvements in processes and apparatus for the wet-separation of the constituents of mineral and other pulp
IPC: B03B5/64
Filed: 1926-08-30
Abstract: 264,129. Martyn, T. G. Jan. 7, 1926, [Convention date]. Stationary-vessel wet-separating apparatus. - The constituents of pulp containing sand &c. are separated by flowing the pulp substantially horizontally between spaced surfaces so that matter which tends to separate gravitationally from the stream reaches one of the surfaces after a short vertical movement, and is then somewhat protected from the stream, the confining surfaces being inclined so that the matter gravitates along the surface and out of the stream. Fig. III shows an apparatus consisting of a four-walled box 4, 5, 6, converging to a discharge slot 7, and containing two sets of inclined partitions 10, parallel to the converging sides 4 of the box, forming settling-chambers 11 between them. The pulp flows through a grating 24 into a chamber 15, and thence through the chambers 11 to the outlet chamber 17; these chambers have perforated baffles 20, 21, and the feed chamber has a second baffle 26. The heavier sand falls vertically on to the inclined surfaces of the partitions 10, and slides down them to the sorting-apparatus 19, there to be further treated. Buoyant matter rises to the underside of the partitions 10, and is skimmed off from the surface of the liquid. Figs. V and VI show an apparatus, which may form part of a pressure or vacuum system, for dewatering slime and clarifying liquids. It consists of a cylindrical vessel 31, with end covers 32, divided by parallel rectangular partitions 10 forming settling chambers 11. Pulp enters by a pipe 37, and, passing a distributing baffle 38, flows substantially horizontally through the chambers 11 to the outlet chamber 34 and the discharge, the heavier constituents sliding down the partitions to the sludge-collecting chamber 35 and the outlet 40. Air bubbles and other buoyant matters rise into the collecting-chamber 36, and pass away through the float valve 41.

Title: Improvements in or relating to a method for liquid treatment of filamentary material, and apparatus therefor
IPC: D06B1/02
Filed: 1944-11-02
Abstract: <PICT:0587599/IV/1> Filamentary materials, such as threads, yarns, filaments, films, fibrous material in sheet form, or textile fabrics, are treated with liquid by passing linearly through at least one pair of colinear opposed jets of liquid, comprising a jet co-directional with the materials and a counter-directional jet which meet to form a turbulent zone.  Liquid is supplied under pressure from a tube 1 through branch tubes 2 to emerge from a series of colinear tubes 4 as jets which impinge upon opposed jets to form turbulent zones 8.  The filamentary material is passed linearly through the tubes 4 and is treated in successive sequences by a counter-directional jet, a co-directional jet and a turbulent zone of liquid.  Jets of liquid may be prevented from issuing from the first and last open ends of the tubes 4 by the application thereto of air currents.

Title: Electro-medical apparatus for stimulating current therapy
IPC: H03K5/00
Filed: 1952-08-26
Abstract: 746,665. Electromedical appliances. SIEMENS-REINIGER-WERKE AKT.-GES. Aug. 26, 1952 [Aug. 27, 1951], No. 21461/52. Class 81(2). Electromedical apparatus comprises an impulse generator for generating sequences of triangular impulses and having two controlling elements which establish time constants so that the impulse time and interval time may be adjusted independently of one another, an adjustable impulse amplifier to amplify the impulses to such a degree that an impulse limiter following the amplifier converts the impulses into rectangular impulses. Triangular impulses are generated by a multivibrator 1 which is triggered by a gas triode. The pulse width of the impulses produced is regulated by adjusting resistances R11, R12 and a condenser C5. The interval between the impulses is regulated by adjusting a condenser C1 in the gas triode circuit and a resistance R1. These impulses are then passed to a potentiometer R15 of an amplifier 2, the potentiometer R15 serving to adjust the amplitude of the amplifier input so that rectangular pulses are produced after subsequent limiting of the output by a diode limiting device 3. The resultant rectangular wave form is caused to pulsate if required by the addition of triangular pulses from a circuit 5, the pulsating rectangular impulses being passed through a three-stage negative feedback amplifier 4 to the patient. The circuit 5 is in the form of a surge impulse generator or a blocking oscillator controlled by a switch in one position of which the surge impulse generator is disconnected from the limiter 3 and the multivibrator 1 is disconnected from the limiter 3 so that the current in the limiter 3 and the amplifier 4 can be measured. In second position of the switch rectangular impulses alone are applied to the patient and in a third position of the switch rectangular impulses together with surge impulses from the surge impulse generator 5 are applied to the patient.

Abstract: 714,932. Moulding rubber soles onto footwear. DUNLOP RUBBER CO., Ltd. Aug. 26. 1952 [Sept. 13, 1951], No. 21517/51. Class 87 (2) Apparatus for making footwear having an integrally moulded sole and galosh comprises a press having a stationary lower platen 2 and an upper platen 7 movable relatively to it, means for locating a last on the lower platen, a sole moulding position attached to the upper platen, a pair of galosh moulding portions 18 located one on each side of the last locating means each portion being slidable into and out of a moulding position, a pair of push rods 19 reciprocable by means of the upper platen, and a bell crank lever 27 for each galosh moulding portion pivoted on the lower platen, one end of the iever being pivotally attached to a galosh moulding portion and the other end of the lever being movable by the push rods whereby downward movement of the upper platen moves the galosh moulding portions into moulding relationship with the last. The last 9 is located on the platen 2 by a dowel 15 which projects from its base into a slot 14 in the platen and is engageable by an adjustable stop 14a. The sole moulding plate 3 is bolted to the platen 7 and has a heater plate 12 screwed to it. The upper platen 7 is movable by a hydraulic cylinder and piston 4, 5 and is guided by pillars 11 The push rods 19 are moved by upward and downward movement of the platen 7, the downward movement being transmitted through springs 24 bearing on adjustable collars 22. The galosh moulding parts 18, with beater plates 17, are mounted on blocks 16 which are slidable on the lower platen 2. A pair of last supporting plates 31 are pivoted to the base of the press by parallel linkage so that, when swung into position, a slot 33 in each comes into line with the slot 14 in the lower platen 2. The lining and upper of a shoe to be produced are placed on a last 9 located in the slot 33 of a plate in its outswung position, the unvulcanized rubber sole is laid in place and a strip of rubber forming the galosh is wrapped round the sides of the shoe and the shoe sole. The support plate and last are then swung in and the last is slid from the plate on to the lower platen 2. The press is then operated to move down the platen 7. The push rods 19 cause a frame 25 to descend, the movement of which causes bell cranks 27 to move the parts 18 inwards to mould the galosh. Further downward movement of the platen 7 is allowed by the springs 24, and the plate 8 therefore pressed on the sole. Heat is then applied to the heater plates, and during the vulcanization another shoe is assembled on the other plate 31. A continuous shoe moulding cycle is therefore possible.

Abstract: 1,220,868. Selective printing. INTERNATIONAL BUSINESS MACHINES CORP. 7 May, 1968 [26 May, 1967], No. 21554/68. Heading B6F. [Also in Divisions F1 and F2] Pneumatic hammer impression action.-A print hammer 1 is actuated by pneumatic pressure by a pneumatic circuit including a valve 4 having a normally open channel, fluid being supplied to the valve 4 to effect an impression and the channel being closed after a predetermined interval by fluid pressure. In a first embodiment, Fig. 2, a valve 5 having a rest condition on which a port 11 is connected to atmosphere at 10 and a port 9, connected to compressed air supply means 8, is closed, is switched by an electromagnet 6 to interconnect the ports 9, 11 and permit air to pass to a cylinder 2 connected to the hammer 1. Air is also permitted thereby to flow through a constriction 14 to close the valve 4 after a predetermined time interval, connecting the port 15 supplying the cylinder 2 to atmosphere at 16. After the valve 4 has closed off communication between the supply means 8 and the cylinder, the electromagnet 6 is de-energized to close the valve 5 through a spring 7 permitting the air holding the valve 4 closed to flow to atmosphere at 10, and the valve 4 to open under the influence of a spring 17. In a modification, Fig. 4, a foil valve 20 is employed in place of the valve 5. A valve 24 is normally closed, under which condition a thin foil 27 is urged by air pressure to close a port communicating via a line 22 with the valve 4. The valve 24 may be opened electromagnetically through a lever 26 to connect a line 23 to atmosphere at 25, the foil then closing the port leading to line 23 and permitting flow of air along line 22 through the valve 4 to operate the hammer 1. Some air also passes through the constriction 14 to close the valve 4 and connect the cylinder 2 to atmosphere at 16. While the valve 4 is open, air pressure in a line 23 acts to urge a second foil 35 in a foil valve 30 to close a line 32 to atmosphere. When the valve 4 is closed the pressure in line 33 drops and the foil 35 opens the line 32 to reduce the pressure upstream of the foil valve 20. A further modification (Fig. 3, not shown) includes the foil valve 20 of Fig. 4 but replaces the foil valve 30 and line 33 by a variable throttle (28). The fluid pressure circuit can be assembled in a monolithic block by punched, die cast or injection moulded plastics plates (39a ... 39j), Figs. 5, 6, not shown, compressed between metal plates (37, 38), the plastics plates being formed with apertures accommodating piston slide valves equivalent to the valves 4, 5 and slots defining the air lines. A line of hammers 1 may co-operate with type elements (82), Fig. 1, not shown, mounted on flexible fingers (81) assembled on a reciprocating bar (80).
