Title: Improvements in method of making liquid filled golf ball cores and other rubber shells
IPC: B29D99/00
Filed: 1948-11-22
Abstract: 655,525. Making golf-ball cores and other rubber shells. UNITED STATES RUBBER CO. Nov. 22, 1948, No. 30285. Convention date, May 1, 1948. [Class 87 (ii)] [Also in Group XV] Rubber shells such as liquid-filled golf-ball cores are formed by making an envelope from two rubber sheets, filling it with a predetermined quantity of liquid such as boiled water, sealing the envelope after excluding air therefrom and pressing the filled envelope between a pair of dies having one or more pairs of mould cavities, thus producing a number of filled shells joined by webs. The shells may be removed from the webs, vulcanized in moulds and if necessary cut open and emptied of liquid. As described, sheets of raw rubber 11, 13 with anti-tack material such as sugar on one or both opposed faces are taken from rolls and fed between dies 151, 17 which press the sheets together round the edges of the dies, except at one point to provide a filling aperture. The formed envelope is simultaneously cut from the rest of the sheets 11, 13 by means of the knife-edge 20. The envelope 23 is then supported in a vertical position on a stand 25 and a measured quantity of liquid introduced from a funnel 28. A hinged plate 30 is raised to squeeze out air and a sealing-bar 31 pressed across the filling opening to seal the envelope. The envelope is then heated in a water-bath and placed between moulding dies 39, 40 in a press, the dies having a number of pairs of hemi-spherical co-operating cavities 46, 47. The die 40 has rollers 43 running in guides 44 in the press so that it can be readily removed therefrom. Pockets 59 are formed in its upper surface to accommodate cutters 60 on a die-plate 45 fixed in the press. Dowels 48 align the various die-plates. With the filled envelope between the dies 39, 40, the press is closed by a hydraulic piston 41 and the liquid and rubber sheet forced into the cavities, the two sides of the envelope being sealed together in the spaces between the cavities. The press is then opened, the die-plate 40 removed, and the press again closed to cause the cutters to blank out the formed shells. These are then removed to vulcanizing moulds for curing. The cutters 60 are so shaped as to squeeze the rubber adjacent the edges of the cavities to strengthen the seal at these places. The dies 46, 47 have vent-holes 52 to prevent trapping of air therein when the press is closed and have passages 53, 54 for cooling liquid. If the shells are for medical bulbs &c. they are cut after vulcanizing and emptied of liquid. The Specification as open to inspection under Sect. 91 states that the shells may be made from material other than rubber, sheets of which will bond together under pressure, and refers to making shells of rounded but non-spherical shape. This subject-matter does not appear in the Specification as accepted.

A circular knitting machine producing cut or uncut pile fabric from aground yarn plated with a pile yarn comprises one set of loop forming elements mounted behind the needles for measuring pile yarn into loops preparatory to its formation into knitting stitches and a second set of such elements performing a similar function for a body yarn, and cams operable to advance the loop forming elements to release the body yarn during stitch forming action of the needle. While retaining the pile yarn loops taut. The machine includes a needle cylinder 13 having needles 15 and a dial 22 provided with pairs of sliding yarn measuring elements 24, 25 each pair being disposed so as to be projectable between two adjacent needles. Each element has a hook 26, 27 respectively, the lower element being provided with a notch 35 behind its hook. While the needles are raised a pile yarn 11 is fed to the hook 26 of the advanced element 24 which is then retracted by an adjustable dial cam to measure the pile yarn between the needles. The body yarn 10 is fed to the hook 27 of element 25, which then retracts to measure the body yarn loops. The needles descend, elements 24, 25 advancing slightly to avoid any strain on the loops, the beards pressed by a shoe or disc 32. As the needles approach cast off level the elements 24, 25 are moved outwardly, the latter moving further than the former so that the pile yarn loop drops from hook 26 into notch 35. After the old stitches have been cast off the pile loops may be released from the elements 25 either by cutting by a disc 36 to form cut pile, or the elements 25 are retracted to clear the pile loops as the needles rise slightly to slacken the loops and allow them to ride up out of the notches 35. The cut parts of cut loops are removed by vacuum, blowing or brushing, and the cut or loop pile brushed under the dial 22. The machine may be of the rotating or the stationary cylinder type, and the needles may be latch needles or bearded needles as shown.

IPC: B65G39/02
Filed: 1967-07-03
Abstract: 1,178,047. Rollers. MIKROVAERK A/S. 3 July, 1967 [4 July, 1966], No. 30558/67. Heading F2U. [Also in Division B8] The belt-carrying surface of a roller for a conveyer belt 4 is formed by a series of bars 3 which are longitudinally displaceable and which, at least while they are disengaged from the belt, are urged towards an intermediate position. The bars are received in recesses of hub discs, 2 and have end abutment against stationary cams 12 for the positive return of the bars to their intermediate position as, during their rotary movement, they are gradually disengaged from the belt. Stationary end discs 5 have flanges 7 which keep the bars 3 in place in relation to the discs 2. If the belt 4 runs obliquely, e.g. at the top and to the right of the Figure, the righthand flange 7 exerts pressure on the belt which is displaced to the left together with the bars 3 which, at the particular moment, are in engagement with the belt. As these bars become disengaged from the belt their ends engage the cams 12 which return the bars to their central position. The cams 12 may be provided on elements separate from the discs 5 and outside the discs. The ends of the bars 3 may then extend through openings in the discs which then rotate with the bars.

Abstract: 934,698. Analogue electrical calculating apparatus. GENERAL PRECISION Inc. Sept. 8, 1959 [Sept. 15, 1958], No. 30671/59. Class 37. [Also in Group XL (c)] In an electronic multiplying apparatus, a transistor switching circuit 121 is supplied over line 108 with a square-wave pulse signal time-modulated by a first analogue voltage Vy applied at terminal 120 and with a second analogue voltage Vx applied at terminal 125, an output proportional to the product of the voltages being obtained, by filtering the output therefrom. The transistors T1, T2 comprising the switching circuit are of opposite conductivity types with their emitters commoned. A sawtooth waveform from a generator 100 is applied with the first analogue voltage as a controlling bias to a transistor or electronic limiting amplifier 107 which saturates with a few multivolts at 106, whereby the output pulses on line 108 are time-modulated according to the value of the first voltage. Feed-back is provided by a second transistor switching device 112, fed also from the output on line 108, wherein the pulse amplitudes are strictly limited in accordance with a voltage applied to terminals 114, 115. This may be retained constant if switching circuit 121 is to multiply Vy by Vx but may be varied in accordance with another variable to effect division. The input Vx is applied to the collector of transistor T1 through a unity gain polarity inverting amplifier 126 and directly to the collector of T2, the transistors being rendered conductive alternately as the output voltage of the pulses on line 108 exceeds the Vx voltage in the proper direction. Filter 123 provides the output proportional to the product. Specification 908,518 is referred to.

Filed: 1933-11-08
Abstract: 406,956. Fuel injectors. BOSCH AKT.-GES., R., 4, Militarstrasse, Stuttgart, Germany. Nov. 8, 1933, Nos. 31034 and 31035. Convention dates, March 13 and May 11. [Class 7 (iii).] In injection nozzles having a valve or needle b raised by the fuel under pressure against the action of a loading spring m, the resistance to movement during the initial period of the injection increases at a greater rate than the force which tends to continue the opening movement, so that this period forms a substantial part of the whole time during which the valve is open. The valve has a needle z which moves in the nozzle passage with some clearance and gives during this initial period the narrowest cross-section through which the fuel flows. The inclined surface forms the closure for the injection and a splayed distributing projection may extend beyond the needle z. The throttling passage may be placed on the inlet side of the valve surface y. In another construction there are two inwardly inclined faces 13, 11, Fig. 9, extending from the needle z and a deflecting cone 12 beyond these surfaces. The opening movement of the valve is limited by a stop i.
