Filed: 1968-09-03
Abstract: 1,192,115. Dispensing articles. VENDO CO. 3, Sept., 1968 [13 May, 1968], No. 41760/68. Heading A4T. A dispensing machine has a refrigerated cabinet housing columns 12 stacked with canned or bottled beverages 16, each column having a loading opening 20 and a releasing mechanism 14, and each column being provided with a rack 10 housing stacked cans, said rack having an opening 54 aligned with opening 20. To reload column 12 with pre-cooled cans from rack 10, the lowermost can 16a is moved upwardly and shifts all the cans thereabove upwardly through opening 54. This swings a panel 48 about shaft 44 from the normal position shown where it closes opening 54 to a deflecting position shown in dotted lines so that cans from the rack are deflected into column opening 20. Movement of panel 48 beyond the deflecting position is prevented by engagement of a shoulder 58 on a pivot bearing 50 of the panel with a leg 74 of a latch 62 which has been shifted to its upper position (see dotted position of Figs. 3 and 4). To reload rack 10 with cans that are not pre-cooled, latch 62 is moved down and panel 48 swung beyond its deflecting position to render opening 54 accessible. Columns 12 may be serpentine or vertical.

Abstract: 1,242,398. Feeding tobacco. MOLINS MACHINE CO. Ltd. 13 Sept., 1968 [15 Sept., 1967], No. 42270/67. Heading A2C. In an apparatus for feeding cut tobacco from a supply to form a continuous flow in the manufacture of tobacco products, the shorts are collected from the supply and fed through the interior of a hollow rotating drum which imparts a tumbling action to them as they pass therethrough and thereby mixes them and the thus mixed shorts are incorporated into the tobacco flow. As shown in Fig. 1, tobacco from a hopper 1 is fed as a layer on a carded drum 4 past a carded refuser drum 5 to be picked off by a picker roller 6 and thrown on to an endless belt conveyor 8 to produce a tobacco filler. Shorts remaining on the outer surface of the drum 4 are removed by a carded roller 7 and pass into a shoot 9 together with shorts from the bottom of the hopper 1 that pass between the drum 4 and the roller 7. The shorts then pass a vaned roller 11 into an air duct 10 for pneumatic transport through a pipe 12 into the interior of the drum 4. On entering the drum 4, Fig. 2, the shorts are deflected by a plate 18 to one end of the inner cylindrical surface thereof which is provided with tapering axially extending ribs 51. These ribs 51, in conjunction with the rotation of the drum 4, smooth and blend the shorts and cause them to progress to the other end of the drum for discharge on to a vibrating tray 14 and thence on to the conveyer 8. The shorts are scattered by the tray 14 more or less uniformly over a limited portion of the width of the conveyer 8 so that they will be contained in the main portion rather than the outer portion of the subsequently former filler stream, as described in Specification 1,101,071.  In a modification, Fig. 5, the drum 4 includes two frusto-conical sieves 19, 20 that separate the shorts into three flows that are subsequently recombined as they pass out of the drum. In another embodiment, Figs. 6 to 8 (not shown), the shorts are tumbled in the interior of the refuser drum 5 and are fed into the main tobacco flow at the mouth of a chimney (3) up which the tobacco is conveyed pneumatically to be formed into the filler stream. In a further embodiment, Figs. 9 to 11 (not shown), the shorts are tumbled in the interior of the shorts removal roller 7.

Abstract: 1,141,253. Prevention of corrosion in heat exchange tubes by enamelling. CKD PRAHA OBOROVY PODNIK. 22 Sept., 1966 [23 Sept., 1965], No. 42312/66. Heading C1M. A method of preventing corrosion in heat exchanging tubes, particularly tubes of less than 16 mm. diameter, comprises applying an enamel slip to the inner walls of the tubes, the slip being prepared by grinding a mixture of enamel frits and mill additions in a non-aqueous medium, and then blending the ground mixture with water and filling the resulting enamel into the tubes arranged vertically, the excess slip being drained out from the tubes within a shorter interval of time than that within which the enamel slip can reach the maximum limits of yield value i.e. the minimum shearing force that must be applied to start laminar flow and thereupon drying and firing the enamel layer. The enamel frits and mill additions may be ground in the dry state, or in a non-aqueous liquid, which after grinding is allowed to evaporate. An enamel layer of uniform thickness is obtained, the thickness depending on the viscosity of the enamel slip.

Abstract: 951,052. Speed governors. UNILAG Ltd., and H. E. R. THOMAS. March 6, 1961 [Dec. 14, 1959], No. 42460/59. Heading G3B. A member 1 is connected through a pin and slot connection 12,14,to a disc 10 which has free motion in one direction and retarded motion in the opposite direction, whereby the motion of the member 1 is retarded while the pin 12 remains in the branch 15 of the slot but is unimpeded when the pin is opposite the longitudinal part 14 of the slot. The disc 10 is mounted on a shaft 9 connected through a free wheel to an escapement, vane wheel or equivalent retarding member, as described in Specification 613,328, so that clockwise motion of the disc 10 is free but anticlockwise motion is controlled by the retarding device. When member 1 is returned to the left, it moves freely and the pin 12 moves down into the slot portion 15 as the disc 10 is rotated. When member 1 is moved to the right, its movement is retarded by the action of the retarding device in the disc 10, until the pin is opposite the slot portion 14 when member 1 is free to move unimpeded until its far end contacts the pin 12. The amount of retarded movement of the member 1 is adjusted either by an adjustable stop 16 limiting the initial portion of the member or by adjustment of the member 5 along the member 1.

Abstract: 1,096,696. Machines with permanent magnets; insulation; coils. HONEYWELL Inc. Sept. 23, 1966 [Sept. 23, 1965], No. 42513/66. Heading H2A. In a D.C. electric motor with a multi-pole stator having between itself and a coaxial magnetic flux return member a coaxial shell rotor of annular cross-section, the rotor includes a plurality of coils of wire which are encapsulated to form the shell, each of the coils being only as thick as a single wire in the radial direction of the rotor, and the plurality of the coils being so arranged that no more than two thicknesses of wire occur in the radial direction, and commutator means. As shown, the stator 12, permanently magnetized, is outermost, and includes four polepieces 16 with pole faces 18; the magnetic flux return member 26 is apertured to receive shaft 42 of the rotor 43; the rotor coil assembly occupies annular space 27. Four brushes (not shown) engage the commutator 54. The stages in manufacture of the rotor are as follows. Wire having a coating compound thereon is wound as a deformed (hexagonal) spiral in one plane with successive loops adjacent so that the coil has the thickness of a single wire. After formation, the coil is heated by current flow to melt the coating to hold the coil together. Several such coils are arranged, by positioning rings, around a cylindrical former, each coil overlapping an adjacent one so that no more than two thicknesses of wire occur in the radial direction of the rotor at any part of the periphery of the coil assembly. The coils are then spirally laced with a silk thread attached thereto by activating the coating with solvent, the positioning rings are removed, and the entire coil assembly is bonded into a self-supporting structure by activating the coating, and clamping till dry. This self-supporting coil shell is assembled on an insulating collar (not shown) axially inward of and spaced from commutator 54 on shaft 42, and the lead wires are connected to the commutator bars. Finally, the coil assembly is encapsulated from end to end with insulating material which at the same time extends to, and engages with, the rotor shaft in the region between the insulating collar and the commutator; it also covers the lead wires and their commutator connections. Preferably the encapsulating material consists of a polyester resin and a sintered metallic oxide filler in proportions which give the material a coefficient of thermal expansion substantially equal to that of copper.

Abstract: 1312000 Cutting ribbon glass CENTRAL GLASS CO Ltd 8 Sept 1970 [10 Sept 1969] 43013/70 Heading C1M A continuous, moving glass ribbon is cut transversely by driving a cutter mechanism 6 at right-angles to the direction of movement of the ribbon from one side thereof to the other and simultaneously driving a cutter 38 mounted on the mechanism 6 in the direction of and at the same velocity as the ribbon movement, returning the cutter 38 to its initial position when the mechanism 6 reaches the other side, and returning the mechanism to the first side of the ribbon after a predetermined time interval whereby the ribbon is cut a second time a predetermined distance from the first cut. The mechanism 6 includes a carriage 24 slidable on a guide rail 7 extending across the ribbon path and is moved by means of a cable 10 which is trained over sheaves 13 and 14 located at opposite sides of the ribbon path, the sheave 14 being driven by an electric motor 15. The carriage carries two guide bars 28, 28<SP>1</SP> which in use extend from the carriage in the said direction of movement. A T-shaped arm 36 is slidably mounted on the bars 28, 28<SP>1</SP> and has the cutter 38 depending therefrom. The arm 36 is driven by a screw 30 threadably engaged with the arm 36 and rotated by an electric pulse motor 35 acting through gear and pinion 33, 34. The velocity of the glass ribbon is detected by a roller 19 in contact with the ribbon which operates a pulse generator 18, the amplified pulses from which are used to drive the motor 35. To control the cutting operations, pulses from the generator 18 are passed to a preset counter which counts the pulses and generates a signal when a predetermined number of pulses have been counted, i.e. after a predetermined length of the ribbon has passed the roller 19, the signal causing an electric motor control circuit to energize the motor 15 in a forward or reverse direction and causes a pulse motor circuit to first allow amplified pulse, to operate the motor 35 and secondly when the carriage has reached the end of its travel to drive the motor 35 in a reverse direction and at a higher speed employing a signal from a frequency signal generator.
