Title: Improvements in and relating to chewing gums and the production thereof
IPC: A23G4/00
Filed: 1929-12-21
Abstract: In the preparation of chewing gums, "the gum or a part or a component thereof is treated with a basic agent, for instance an alkali, or with an acidiferous agent, for instance an acid, or one part or component of the gum is treated with a basic agent and another part or component with an acidiferous agent.  The term gum . . . includes all gums and resins or gummous and resinous substances."  Preferably two different gums are used, e.g. pontianac also called jelutong or pebang, and chicle.  The pontianac is boiled in water and to the water is then added a basic agent.  The chicle is similarly treated with an acidiferous agent, both gums then being bleached, e.g. with hydrogen peroxide or chloride of lime, which is added to the water. The gums are then washed preparatory to mixing with flavouring substances and, perhaps, untreated gum and a filler, e.g. starch, magnesia, talcum.  Elemi and burgunder (gallipot) may be treated.ALSO:In the preparation of chewing gums, "the gum or a part or a component thereof is treated with a basic agent, for instance an alkali, or with an acidiferous agent, for instance an acid, or one part or component of the gum is treated with a basic agent and another part or component with an acidiferous agent.

Title: Improvements in or relating to swing tray conveyors for bakery plant
Inventor: BAKER DAVID KING
IPC: B65G17/48
Filed: 1958-12-05
Abstract: 899,748. Endless swing-tray conveyers. BAKER PERKINS Ltd. Nov. 30, 1959 [Dec. 5, 1958], No. 39243/58. Class 78 (1). In an endless swing-tray conveyer of the type wherein each tray T has a moving article-carrying floor formed by a belt 5 resting on the base 4 of the tray and passing around the edges 3a, 4a of the tray to form an endless loop, means is provided at a discharge position for tilting the tray backwards and at the same time engaging the ends of a cross-bar 12 secured between the ends 14 of the belt to cause the latter to slide over the base of the tray to deposit the articles by a " peeling " action on a receiving- surface R. The bar 12 is secured between the belt ends 14 by double hook members 13 and is carried between a pair of arms 10 swing- able about inward extensions 8 of the tray pivots 6 which are mounted in endless driving chains C. The ends 15 of bar 12 project through arcuate slots 18 in end walls 1, 2 of the tray between which base 4 is secured. An arm 16 carrying a roller 17 is secured to each projecting end 15. A second roller 19 is secured to each of the walls 1, 2 above the corresponding roller 17. At the discharge position there are provided two levers 24, 34 respectively carrying abutment members 21, 22. The levers are oscillated in timed relation with the chain drive by a cam 28 having cam grooves 33, 38 in which follower rollers 32, 37 on the respective levers engage. The arrangement is such that, as each tray passes the discharge position, abutment member 22 is moved forwardly from behind and below the roller 17 to engage the latter, and at the same time member 21 is moved rearwardly so that its rear face 27 engages roller 19 to tilt the tray, so causing belt 5 to slide around base 4 and discharge the articles. After delivery of the articles to surface R the tray is maintained tilted until clear of the discharge position by roller 19 travelling along surface 39 of the abutment member 21, after which it returns to normal position. The bar 12 is returned to its initial position by a plate 40 operating in conjunction with a disc 41 to form a guide funnel through which the rollers 17, 19 are passed. A spring 20 maintains the bar 12 in its returned position.

[Also in Division HI] A tubular container has a plastics cylindrical side wall 1 having a metal disc 5 bonded to one end by a heat seal. An annular rib 6 provided on the disc defines a flange of approximately the same width as the thickness of the container. To manufacture the container, the cylinder 1 is slidably positioned in a tube 2 and the disc is placed in vertical alignment below on a mandrel which has a rib complementary to the rib 6 on the disc for retaining the disc in position. The  disc is heated to a suitable temperature, e.g. for a polythene cylinder the heating range is 320‹ to 350‹ C. The mandrel is displaced upwards so that the disc engages the bottom end of the cylinder and adheres there. During this process the periphery of the bottom end of the side wall is pushed outwards to form a bead 7. The metal disc may be roughened, e.g. by sand blasting, before heating, to improve the bond. The container may be used as a casing for dry cells.

Abstract: 1,271,667. Capacitor pick-up. SONY CORP. 18 Aug., 1969, No. 41167/69. Heading H4J. In a capacitor type gramophone pick-up, a diaphragm or flexible bellows is driven by the stylus and vibrations of the stylus are transmitted therefrom as variations in air pressure. These air pressure variations are transmitted to a conductive diaphragm forming one electrode of a capacitor and movable relative to a conductive plate forming the second electrode of the capacitor. A stereophonic pick-up has a stylus arm 118 connected by a coupler 107L to a front diaphragm 101L forming a wall of an air chamber 103L which communicates through a duct 105L with a rear air chamber 104L. Air chamber 103L is smaller than air chamber 104L. Vibrations of a stylus 120 are transmitted to the front diaphragm 101L and variations in air pressure in the system cause vibrations of a rear diaphragm 102L, to vary the distance between it and an apertured, conductive, back plate 108L. The rear diaphragm 102L may be of metal foil but is preferably of metal-coated polypropylene or polyester which may be prepolarized to provide an electret. If it is not prepolarized, a power source is provided. The stylus arm 118 is connected by a second coupler 107R with a front diaphragm 101R, vibrations of which are in like manner communicated to a rear diaphragm 102R. In another embodiment having a removable stylus sub-assembly (211), Figs. 5, 6 (not shown), a cantilever stylus arm (210) and two couplers (209) are provided, each of which presses a rubber bellows (224). Movement of a bellows (224) causes movement of a movable metal-coated electret diaphragm (219) relative to a conductive back plate (216). An amplifier is included in the cartridge and may be powered by a battery also in the cartridge. A circuit is described (Fig. 3, not shown) by which the output of a capacitor pick-up is connected to a F.E.T. input stage.

[Also in Division G1] In a station or channel indicator of a radio or television set having a tuning arrangement 1 and an indicating cylinder 3 with an indicating mark extending helically around the cylinder periphery and visible through an axially extending window of a scale 2a, the indicating cylinder 3 is driven via gearing 6 by the rotary system of an electrical measuring instrument 4 connected in an electrical circuit 5 in which the current is controlled by adjustment of the tuning arrangement 1. As shown the tuning capacitor of a H.F. stage of a radio receiver is ganged to a potentiometer 5a so that adjustment of the tuning capacitor varies the current through the control circuit 5. The instrument 4 (Fig. 2) drives the cylinder or drum indicator 3 via gearing 6 and the cylinder is spring biased in one direction to an initial position to eliminate backlash in the gearing. A wave or channel switch 1a is coupled via elements 7, 8, 9 to a rotatable mask 2 which has windows 2a corresponding to the different wave or channel selected. The helical indicating mark on the drum 3 can be seen through the window selected and co-operates with a scale marked along the edges of the window. The mask 2 is located in its selected position by at least one spring 13. The mask 2 and indicator drum 3 may be of plastics material having the same coefficient of thermal expansion and may be illuminated at 15. The mask may be circular as shown or may be square or polygonal in shape (Fig. 4, not shown) and may be viewed from an aperture (11) in a housing (12).
