Abstract: 1336248 Continuous casting CONCAST AG 19 April 1971 [27 Jan 1970] 20224/71 Heading B3F A starter bar head has a coupling piece 2 (of height 3) and an intermediate member 4 (of height 5) by which it is linked to the bar 6; the piece 2 has a hook-shaped slot 7 in which the cast metal can solidify to form a connection with the bar head (until the head is tilted or rotated for release), the breadth of the piece 2 being adjustable to various mould breadths, with a change in length of the slot 7. The piece 2 can be replaced by pieces of different adjustable ranges. The breadth of the member 4 corresponds to the minimum mould width. The piece 2 includes at least one slide 9 by which a side can be extended to broaden the piece as indicated in chain lines in Fig. 2. The end of the slide 9 mates with and closes an end of the slot 7 while its main portion, slidably attached by a stud 14 on the body 10 of the piece 2, extends the profile of the slot, Fig. 1. The slide extension 9 is secured in position by wedging of its mating portion by a bolt (13). In other embodiments, the coupling piece 2 is broadened by the addition to one or both sides of the piece, or by the insertion between separable halves of the piece, of extension pieces which are formed with portions of the slot 7. For separation, the separable halves may be on pivoted arms 45, Fig. 7, of the intermediate member 44 to open for the extension piece 60 or be movable along a slideway (81) by which they are attached to the intermediate member (82) on which the extension pieces (84) are pivoted to be swung up between the halves as required. The halved coupling piece arrangements may be combined with the slides 9 of Figs. 1 and 2 for more precise adjustment of breadth. The coupling piece may be adjusted by extension members lacking portions of the slot, in which case the slot length is varied by removing inserts which limit that length.

Abstract: 1,163,501. Reinforced foamed plastics laminate. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 2 May, 1967, No. 20269/67. Heading B5N. A foamed plastics product is reinforced with an open mesh screen 14 made of filamentary material, the screen having reinforcing elements which are thicker than the filamentary material secured to the junctions thereof. In one method of making the product a reinforcing screen 14 is placed in a mould 10, which may be lined with a release agent, spacing blocks 16 are placed on the screen, and a second screen 15 identical with the screen 14 is placed on the blocks. Before or after laying of the screen 15 a foamable liquid 17 is poured into the mould which is then closed. Foaming then occurs during which the mould may be cooled or otherwise treated, e.g. to cause the foamed plastics to be denser near the surfaces. The screens 14, 15 may be of woven metal wires 18 or glass filaments impregnated with a thermosetting resin, and the reinforcing elements may be blocks 19 of solid, or cellular material such as concrete, plastics or baked porous clay, projecting preferably on both sides of the screen. The foamed plastics material 17 may be polystyrene, P.V.C., urea- or phenol-formaldehyde or polyurethane, and may be elastic or rigid. The spacing elements 16 may be of the same material as the foamed plastics, or of wood. The edges of the screen 14 may be bent upward or downward, or the screen may be corrugated. In an alternative method the product is formed continuously between two spaced moving moulding surfaces. The product may be used in constructional panels.

Abstract: 583,347. Bearings. TOWLER, J. M., and TOWLER, F. H. Oct. 20, 1944, No. 20359. [Class 12 (i)] A self-aligning bearing-arrangement for a shaft subject to deflection under heavy load, such as the shaft of a multi-throw high-pressure ram pump in which the rams are operated by eccentrics on the shaft, consists in mounting the journal bearings in housings which are so supported by flexible arms as to allow tilting of the housings which thus line up with the relative angular deflection of the shaft journals. An eccentric-carrying shaft B of a five-throw ram pump A runs in roller bearings C which are each mounted in a housing provided by a plate member 1 bored to receive the roller bearing and with grooves milled out at the side edges to receive flexible support arms 2 anchored in a vertical base plate 14. The bearing-housing plates 1 and the base plates 14 lie against the end frames 4, 5 of the ram pump but the bearing housing plates are cut away to a reduced thickness on the upper half of one face so that they can each rock about the shoulder line 7 so formed which bears on the end frame 4 or 5. The housing plate and the base plate are formed from a single plate by cutting across at 13 after the milling out of the grooves in the side edges. The roller bearings have their outer races shouldered at 15 for locating against the housings 1. The flexible support arms 2 are made of 80/90 ton steel of Brinell hardness 420/360.

Abstract: 706,478. Endless conveyers. WILSON BROS., Ltd., and MUENDE, P. Nov. 16, 1951 [Aug. 17, 1950], No. 20445/50. Class 78 (1) [Also in Groups XVI and XVII] In a packaging machine (see Group XVII), greetings cards or the like are fed simultaneously from twelve delivery heads 5-16 on to a continuously-driven, endless belt conveyer 2, the speed of the conveyer being so related to the period of delivery of the heads that an successive delivery operations the cards fall substantially one upon another, whereby stacks of cards, each comprising a card from each head, may be obtained from the conveyer. The latter is driven from. an electric motor 3 which also drives the mechanism associated with each head through a main shaft 19 and chain 18. Each head comprises a shoot 17 formed by a bottom wall 23, Figs. 3 and 4, and side walls 26 adjustable laterally to suit cards of different widths. The pile of cards 25 is urged downwardly by a weight 33 on rollers 34 and the lower end card is retained by adjustable' spring strips 39, adjustable rollers 36 and a spring strip 21 which extends upwardly through a recess in an upwardly-curved plate 35 secured to the wall 23. Suction cups 42 are carried by tubes 43 connected by unions 44 to pipes 45 which are connected by flexible pipes 46 and a camoperated control valve to a suction pump 22, the pipes 45 being slidable in a support 47, secured to a shaft 50, and fixed to a block 48 having a pin and slot connection 51, 52 with an arm 53 on a shaft 54. The shafts 50 and 54 are periodically rocked through linkage by cams 58 and 66 on a shaft 59 driven by the chain 18, whereby the suction cups are first moved in the direction of arrow B to remove the end card and then in the direction of arrow E to lower the card between a roller 66A, driven through gearing from the shaft, and laterally-adjustable rollers 68 carried by a mounting 69 which is periodically rocked by a cam 75 on the shaft to move the rollers into co-acting relationships. After the card has been released by the suction cups, the rollers feed it downwardly over a guide 77 into the bight between wooden rollers 79 and a fabric belt 78 driven through gearing from the shaft 59, whereby it is fed to the conveyer 2. Boxes for the reception of the cards are placed on the conveyer between laterally-adjustable side guides 108, Fig. 9, and are released in succession for movement through the machine by a cam 120 on the shaft 19 which operates a push-rod 118 to rock a shaft 114 carrying adjustable pins 121, 122 arranged to engage in front of the rear wall of each box in turn.

Abstract: 225,907. Kinman, T. H. Aug. 11, 1923. Thermionic heterodyne receivers.-In a heterodyne receiving system in which three frequencies, the signal and two sets of local oscillations, are applied to the grid of a valve, a single resultant is taken directly from the valve for amplification or detection. The local frequencies are preferably much higher than the signal frequency. Fig. 1 shows incoming signals from the aerial 2 applied to a valve 1, which is back-coupled at 5, 6 to produce local oscillations, and also receives oscillations from a local oscillator 11. In a modification, Fig. 11, the valve is caused to oscillate at two frequencies due to the back-couplings 5, 22 and 19, 20. In a further modification, the valve is non-oscillatory, and two local oscillators a.re used. Various other modifications are described in the Specification. The output may be audiofrequency. or radio-frequency applied to supersonic receiving apparatus of the type described in Specification 197,405. An acceptor circuit or an impedance may be included in the output circuit so that reaction for the heat frequency of the local oscillations may be obtained, thus permitting the power of these to be reduced.

Abstract: 301,810. Charlton, R. A. Aug. 5, 1927. Envelopes and the like, making.-Apparatus for securing together the two parallel edges of a folded sheet of paper to form an envelope by embossing or crimping them simultaneously, comprises two pairs of toothed, narrow-edged embossing rollers mounted upon two relatively adjustable parallel shafts, the distance between the wheels of each pair being also adjustable, and means for feeding and guiding the folded sheets into the correct position between the wheels. The third edge of the envelope is sealed by embossing in a similar machine provided with one pair of toothed wheels, after the contents have been inserted. The upper pair of rollers A, Figs. 1 and 2, are loosely mounted between collars L on a shaft B supported within end bearings G in housings D, and are adjustable vertically therein by means of wedge-shaped members H disposed beneath the bearings and adapted to be moved inwardly by screws J, a spring K being mounted above each bearing to exert a downward pressure. The lower pair of embossing rollers A are secured upon a shaft C which is supported between bearings fixed. within the housing D and is driven by a pulley W. The lower embossing- rollers engage and drive the upper ones. The folded sheets h may be fed between the embossing rollers by an endless band, or, as shown, they may be fed from a hopper by a feeding-roller Q on a shaft R driven by a, chain and sprocket mechanism from the shaft C. The hopper consists of three angle-brackets N-N<2> mounted upon a fixed base M to form three sides of an enclosure the dimensions of which can be varied by altering the position of the brackets. The fourth side of the hopper is formed by a downward extension 0<1> on a bracket 0 which is mounted on a transverse upper rail P, the space between the lower end of the portion O<1> and the feeding roller being adjustable to form a passage through which only one sheet can be fed. Extensions V on the brackets N<1>, N<2> guide the'papers in the correct position between the embossing rollers. As the papers emerge from between the rollers their leading edge passes between upper and lower supporting guides Z. The embossed band d. Fig. 3, around the three edges a-c of the folded sheet h is preferably at a short distance from the edge of the paper so as to form a plain margin e.
