Title: Improvements in or relating to silk screen printing apparatus
Inventor: FOSTER WILLIAM ROBERT
IPC: B41F15/08
Filed: 1963-02-15
Abstract: 984,204. Printing apparatus. W. R. FOSTER (POLYPRINT) Ltd. Feb. 14, 1964 [Feb. 15, 1963], No. 6334/63. Heading B6C. A silk screen printing apparatus including a screen carrier 10 reciprocable along a horizontal path and a squeegee assembly 14 so supported as to co-operate with the upper surface of the screen 11 comprises a table 17 adapted to support jig elements 19, 20 for any workpiece 18, e.g. a cylindrical plastic bottle, to be printed upon, such table being so arranged that the jig elements 19, 20 are maintained horizontal whilst being moved back and forth in a direction transverse to that of the movement of the screen and along an inclined path between a lower position for workpiece loading and offloading and an uppermost position wherein a workpiece will be disposed below, but spaced from, the undersurface of the screen, there being means adapted when the table is moved into its uppermost position to impart a final vertical upward movement thereto to bring the workpiece into contact with the screen. The screen carrier is reciprocated by a double-acting ram 13 whilst the squeegee assembly 14 is lowered and raised by a ram 16. A workpiece 18, e.g. a cylindrical plastic bottle, is placed between the jig elements 19, 20 whilst the supporting table 17 is in the position of Fig. 1. In the case of a bottle having soft resilient sides the jig element 20 is used to force air into the bottle during stencilling. The table 17 is supported by an undercarriage 21 slidable along a ramp 22 provided on a carriage 23. A double-acting ram 25 connects both carriages, the cylinder 24 of the ram being pivotally mounted on the casing 23 whilst the ram piston 26 is pivoted on the undercarriage 21. The carriage 23 is movable horizontally to a limited extent. In operation, inward movement of the ram 25 raises the workpiece 18 to a position just below the screen 11, a stop 27 preventing further upward movement of the undercarriage 21. The ram 25 is subsequently caused to move further inwardly whereupon the abutment of stop 27 and undercarriage 21 effects movement to the right, Fig. 3, of the carriage 23 such that the workpiece 18 is moved into engagement with the screen 11. After the printing stroke of the latter, a ram (not shown) moves the carriage 23 back to the position of Fig. 3 and subsequently the ram 25 is actuated to move the undercarriage 21 down the ramp 22 to a position, shown in Fig. 1, where the printed workpiece is removed prior to the insertion between the elements 19, 20 of a fresh piece. The rams of the machine are pneumatically operated and the pneumatic circuit is such that subsequent to the depression of a foot pedal or other device a complete cycle will be initiated, the various parts of the machine being caused to operate in correct sequence.

Title: Improvements in application of thermionic valves to production of alternating currents and in relaying
IPC: H02K29/12
Filed: 1918-04-17
Abstract: 155,854. Eccles, W. H., and Jordan, F. W. April, 17, 1918. Vacuum or low-pressure apparatus, arrangements of.-In a method for generating alternating or fluctuating current from direct current, a moving member is arranged to produce, directly or indirectly, an alternating or fluctuating voltage in the control circuit of an ionic tube, so that corresponding variations arise in the current through the anode circuit of the tube. and these variations are used to sustain the motion of the moving member. In the arrangement shown in Fig. 1, the moving-member is a tuning-fork vibrating between two electromagnets A. B, one of which is in the grid circuit and the other in the anode circuit of the ionic tube. The movement of the grid prong sets up voltages in the grid circuit, and the corresponding variations in the anode current traverse the electromagnet B and sustain the vibration of the fork. The tuning fork may be replaced by an adjustable reed or by a lever carried by a spindle capable of torsional vibrations. Instead of exciting the control circuit directly by the mechanical movement of the vibrator, it may be excited indirectly, either wholly or in part, by induction from the anode circuit. Thus the electromagnets may have two windings, one in the anode circuit and the other in the grid circuit, or the electromagnet A may be replaced by a transformer with its primary winding in the anode circuit and its secondary in the grid circuit. The arrangement shown in Fig. 1 can be used as a tuned or selective relay, the primary winding of a transformer T in the anode or grid circuit being used to receive the alternating current to be detected. When used as a relay, the fork may be replaced by a mono-frequency telephone, the frequency of the moving diaphragm or other vibrator being determined by means of an associated circuit comprising an inductance and a condenser. In the arrangement shown in Fig. 5, the vibrations are sustained by electrostatic forces instead of magnetic forces, the electromagnets being replaced by flat conductors A, B in the grid and anode circuits respectively. In this arrangement, a vibrating reed is shown instead of a tuning fork, and a grid leak GL is provided. In another arrangement, Fig. 7, a rotating wheel D with iron teeth T is employed. This wheel may rotate in a horizontal plane between the poles of electromagnets in the grid and anode circuits respectively, the fluctuating currents set up in the anode circuit exerting on the teeth propelling forces which sustain the motion of the wheel. Indirect methods of exciting the grid circuit by induction frnm the anode circuit may be used or the grid circuit may be excited directly by means of a commutator on the spindle of the rotating wheel. Other forms of ionic tube, e.g. a two-electrode tube in which the control current is added to the filament-heating current, may be used.

As shown in Fig. 3, the air nozzle 29 for delivery of the rovings is pivotably mounted on a swivel arm 30, which is jointed to a ring 31 upon which the foam mixing head 24 is rotatably mounted. Clamps 33 are provided for fixing the nozzles in their desired relative positions. This apparatus may be employed for either batch or continuous production. As shown in Fig. 1, the nozzle assembly may be mounted on a carriage 3 movable on a frame 2 over a stationary mould 1. Alternatively, Fig. 2, the nozzle assembly may be disposed above the lower belt 13 of a double belt moulding machine 10. Various relative positions of the nozzle are described (Figs. 4-10, not shown) for obtaining a different distribution and orientation of the rovings in the finished web using the continuous method. In Figs. 4-6 the air nozzle (38) is upstream of the foam nozzle (27) so that the rovings lie towards the bottom of the finished web. Depending on the inclination of the air nozzle relative to the belt 11, the rovings will be deposited in either flat loops (Fig. 6) or will be heaped up. In Figs. 7-9, a reverse arrangement is employed to produce webs having the rovings lying towards the top of the web. Substantially homogeneous distribution may be obtained by directing the nozzles to the same point (Fig. 10). The foam used may be polyurethane, polyisocyanate, polyisocyanurate or polyester. The rovings may be of synthetic or natural fibres, but are preferably glass. Sandwich elements may be produced by using covering foils of paper, plastics, metal, or wood veneer.

Title: Suspension system for vehicles
IPC: B61F5/22
Filed: 1939-03-02
Abstract: 525,858. Railway - vehicle undercarriages. HILL, C. T. March 2, 1939, No. 6821. Convention date, March 7, 1938. [Class 103 (vi)] In a railway or other vehicle the body is supported upon the wheel-carrying units, at points which effect a tilting of the body about a longitudinal axis at or above the centre of gravity, by means of spring elements which yield flexibly for vertical or transverse movements of the body, and torsionally for swivelling movements about a vertical axis. In the construction shown the supporting elements consist of helical springs 88, Fig. 2, located at each side of a central aisle 32 in enclosures 25 and bearing upon upstanding posts 36 carried by a wheel-carrying frame 35. This frame may be part of a unitary four-wheel truck for supporting one end of a single vehicle body or, as shown, may be a composite structure for supporting the two ends of adjacent vehicle bodies in an articulated train. In this construction two half-frames 37, Fig. 4, of hollow box formation are united by bolts 65 passing through transverse members 38, and may be separated to form two single axle units, each of which is fitted with auxiliary guide-wheels 67 carried at the ends of pivotal arms 68. The frames 35 are carried upon the axles 47 by means of leafsprings 54 in combination with rubber cushions 58 on the axle-boxes 50, Fig 9, additional cushions 62 being provided to restrain lateral movement of the axle. Tractive effort is transmitted between the vehicle body and the wheelframes 35 by draw-bars 69 connected at their ends to the body and frames through the intermediary of rubber cushions 74. Vertical, lateral and longitudinal movements of the body 23 cause the springs 88 to be compressed or extended, while swivelling movements stress the springs torsionally. Undue lateral movement is resisted by means of arms 99 mounted upon resilient cushions 107 on the sides of the posts 36 and jointed at their upper ends to horizontal links 101 which in turn are universally jointed to body brackets 123, Fig. 2. Additional links 129, 130 connect the arms 9 to shock-absorbers 126. The tilting movement is controlled by links 133, 132 interposed between the vehicle body and shockabsorbers 131.

Filed: 1943-04-30
Abstract: 566,866. Electric induction heating. RADIO CORPORATION OF AMERICA. April 30, 1943, No. 6881. Convention date, April 30, 1942. [Class 39 (iii)] A strip of steel 1 is inductively heated by a coil 3 having a part 3a which sets up a highfrequency field along the longitudinal direction of the strip, thereby heating the strip by hysteresis losses, and a part 3b which sets up a field at right angles to the first, thereby continuing the heating of the strip by eddy current losses after the hysteresis loss has become zero at a temperature of about 1300‹ F. Each of the parts 3a, 3b may consist of one or more turns of metal tube through which a cooling fluid circulates. In Fig. 4, the coil consists of a strip of sheet material bent to a single loop which encloses the strip 1. The two ends 19 are connected to the supply, and at the opposite end of the diameter of the coil an opening 15 is formed, from which a slit 17 extends to one edge. The passage of current around the coil and around the opening 15 sets up the two fields at right angles. In Fig. 6, steel strip 1 is fed from a reel 21 through guide 25 to heating coil 3 as described above, then through a water-cooled quench block 27, then through a coil 29 similar to 3a which heats it to a lower tempering temperature, and finally through a quench block 31. In modifications, the coils 3a, 3b may be separate and may be connected to the same or different sources, or a simple solenoid may be arranged at an angle to the strip 1 to provide the component fields.
