Filed: 1923-09-24
Abstract: 226,864. Hennig, G. K., and Hupfeld Akt.-Ges., L. Sept. 24, 1923. Actions, pneumatic; windtrunks; combined with other instruments; player-pianos. - A wind-chest of the type comprising a continuous channel with detachable valve units secured on the top and the striking pneumatics secured to the bottom or below, is formed of two side rails united by an unreceseed top coverplate forming a seating surface for the valve units. In a modification, the channel is cut in a solid block with an open bottom or side closed by a plate. The striking pneumatics may form part of the bottom closure of the channel, which may have a lining of cloth, leather, rubber, &c. Fig. 1 shows a wind-chest formed of two side rails 2 united by an unrecessed cover-plate 3 on which a valve unit is secured with the interposition of soft packing material by a hook 28 or coil spring and a spring tongue 27. The valve-box comprises three chambers 7, 8, 9, only the chamber 7 containing the primary pouch-diaphragm 10 being in permanent communication, at 23, with suction. The chamber 8 containing the secondary diaphragm 14, and the chamber 9, are, normally, and the space 20 with which the interior of the diaphragm 14 communicates, is permanently, connected to atmosphere. Actuation of the primary valve 11 therefore connects the secondary diaphragm 14 in the chamber 8 to suction through the chamber 7, operating the secondary valve 15 controlling the striking-pneumatic 4. The top cover of the valve-box is removably attached by screws. The valve apertures may be subdivided as shown at 13<1>, Fig. 4, to prevent entry of dust. Either or both of the pouch-diaphragms may be replaced by plane diaphragms. In another form, the secondary diaphragm is connected to its valve by a lever, the special formation of a space 20 being then unnecessary. In Fig. 9, both the pouchdiaphragms, which are of oblong form, are in a chamber permanently open to the suction, the interior of the secondary diaphragm 35 being connected to atmosphere in the usual manner by operation of the primary valve 48. The hinges of the striking-pneumatics on a wind-chest are protected by a longitudinal plate 50. The windchest may be divided into two separated parts, one part carrying valve units each comprising a primary diaphragm and valve, and the other part, to which the striking-pneumatics are secured, carrying units each comprising a secondary diaphragm and valve. The vertical end wind-passages of the chests may be connected as shown in Fig. 15, by means of tubes 59 and nuts 60, through which pass screws 61 for fixing the whole in the instrument. The striking- fingers, Fig. 19, connected at a to their pneumatics, rest detachably at 64 on their hinge-pins, being held by springs 66 passed beneath the pins. Where other instruments are to be simultaneously operated, the passage 22, Fig. 1, may be branched and lead to a number of striking-pneumatics at a distance.

Abstract: 171,775. Schat, A. P. Aug. 20,1920. Boat raising and lowering gear. - Pulley tackle, more particularly for lowering boats, comprising a top block and a suspended lower block, is provided with means on the lower. block for raising or lowering that block independently of the hauling part of the fall. The standing part 3a, Fig. 2, of the fall 3 instead of being fixed to the block is wound round a compensating drum 4 which can be rotated by worm gear 6 and a chain 10 to adjust the height of the block. The worm-wheel 6 and the drum 4 are fixed on the shaft on which the pulley sheaves rotate freely. Instead of being controlled by gearing, the compensating drum may be braked, in which case the block can only be lowered by this means. For lowering boats, two tackles are employed with a single fall, as shown in Fig. 4, a compensating drum being provided on the lower left-hand block, round which the fall is wound a few turns. The diagonal part 11<c> of the fall serves as a life line. In a modification the part 11<c> connects either the two lower or the two top blocks. A compensating drum may be employed in each tackle.

Filed: 1965-06-08
Abstract: 1,110,701. Receptacle capping machine. LILY CUPS OVERSEAS Ltd. 8 June, 1965, No. 24277/65. Heading B8C. In a machine in which the mouth of a container is closed by placing heat-shrinkable film over it, with its margins extending beyond the container rim and heating the margins to shrink them on to the container walls, the sheet of film is held against the container mouth by a clamp which is movable from a position below a capping head to a portion within the head, where hot air is blown against the free margins of the film. The machine caps a number of containers simultaneously. In the embodiment, a tray 25, Fig. 1, of containers 26 is moved along a conveyer 27 to beneath a heating unit 21 where a web 28, e.g. of irradiated, biaxially orientated polyethylene, is drawn manually from a roll 29, over the open mouths of the containers. The unit 21, carrying the individual capping heads 24, Fig. 4, is then manually brought down on to the covered containers. As the unit 21 is brought downwards, the container mouths are first contacted by sponge rubber covered plates 145, Fig. 12 (not shown), carried by plungers 146 slidably mounted within the heads 24, The web is then cut between the receptacles by a grid-like arrangement of knives 50a, 50b, see also Figs. 6, 7 and 13 (not shown), attached to a bottom wall 80 of the unit 21, through which the capping heads 24 extend. Finally with continued downward movement of the unit, the receptacle mouths move within the heads where hot air, from a chamber 90, is directed through apertures 135 in the capping head walls, Fig. 14 (not shown), on to the margins of the film. Simultaneously, V-shaped cuts (160), Fig. 16 (not shown), may be made in the closures by correspondingly shaped knives (160), Figs. 14 and 15 (not shown), fixed on the ends of shafts 140, on which the plungers 146 slide, to permit release of gases emanating from the contents of the receptacles. The heating unit is formed by an insulated box, Fig. 4, separated into two chambers 90, 91 by a plate 78, to which the heads 24 are removably attached, and which has openings 92 through which air heated in the chamber 90 passes to the lower chamber 91 which is closed by the plate 80. Air, blown into the upper chamber by the blower 48, provided with a flap valve 172 to restrict or prevent inlet of air to the heating chamber when the unit is in its upper position, passes through apertures 92 in plate 78 to the lower chamber and then through the apertures 135. The knives and capping heads 24 are heated by conduction through the plate 80. The clamping plates 145 fall by gravity into their lowered position as the unit 21 is raised but may be spring biased into this position, Fig. 11 (not shown). In a modification, the knives 50a, 50b may be omitted and the bottoms of the heads 24 flared outwardly and their edges sharpened to provide the required knife edges. Reference has been directed by the Comptroller to Specification 827,246.

Abstract: 866,948. Polishing. BOULTON PAUL AIRCRAFT Ltd. July 21, 1959 [July 30, 1958], No. 24532/58. Class 60. A method of polishing the surfaces of articles comprises passing a layer of abrasive-carrying fluid over a surface to be polished by causing the fluid to flow between the surface and a confining surface corresponding in shape to that of the surface to be polished and spaced therefrom by a predetermined distance such as to leave a shallow space for the passage of the abrasivecarrying fluid. A sheet 1, Fig. 1a, is positioned within a die 2 so that the face to be polished is separated from a confining surface 3 by a laminar space 4 communicating with entry and exit apertures 5, 6 for abrasive-carrying air. Modifications for polishing a cylinder, the external surface of a tube, and an article having an S- shaped section are described. In a further modification, Fig. 1e, the concave surface of one article 24 and the convex surface of another article 24 are simultaneously polished in a single die 25 and the articles are then interchanged. The laminar space may be produced by coating the surface to be polished of the article, moulding or casting the die around the coated article, separating the die from the coated article, removing the coating from the coating and/or die, and replacing the article in the die. The abrasive-carrying fluid may pass from the die into a cyclone separator, the re-usable abrasion passing through a valvecontrolled opening into a Venturi passage connected to the source of fluid and to the inlet of the die.
