Title: Belt for moulding small chocolate sticks - has comb through which molten chocolate passes
IPC: A23G1/20
Filed: 1968-04-26
Granted: 1975-11-21
Abstract: Small sticks of chocolate are made by covering an endless belt with heated chocolate and passing the layer formed through a combe with teeth which have been specially designed to produce endless sticks of chocolate with a desired cross-sectional shape. A guard at the ends of the comb prevents chocolate spilling from the belt sides. The sticks are cooled as they progress through a cooling tunnel and are then cut into pieces of the desired length by a guillotine. The length of the individual sticks can be altered by changing the belt speed, and in this method, the use of moulds which have to be first heated and then cooled, is avoided.

Abstract: 1,229,886. Handwriting comparing; fraud preventing. CANON CAMERA CO. Inc. 11 June, 1968 [12 June, 1967 (2)], No. 27764/68. Headings B6A and B6X. [Also in Divisions C4, G2 and H2] A method of concealing and subsequently identifying designs or marks on a sheet 1 such as a check consists of making the mark with a material impermeable to infra-red rays and covering it with material opaque to visible light but permeable to infra-red and identifying the mark by exposing the sheet on one side to infra-red rays to generate a shadow of the mark which is recognized by viewing an ultra-violetirradiated fluorescent member upon which the infra-red image is cast. A design or mark is written with ink impermeable to infra-red, such as ink mainly composed of carbon black, and is smeared with ink opaque to visible light, for example ink mainly composed of oil black, and the surface of the sheet containing the signature is sealed with a thin film 3<SP>1</SP> having the same properties as the ink used for the smearing. A thin fluorescent plate 4, covered on one side with a layer of transparent acetate or polyester (40), Fig. 9 (not shown), or optical fibres (40<SP>1</SP>), Fig. 10 (not shown), is placed on top of the sheet with the fibre layer next to the sheet and an infra-red ray source 5 and a filter 6 passing only infra-red are placed behind the sheet 1 and when the source 5 is switched on an ultraviolet source 7 is switched on simultaneously to illuminate the fluorescent plate 4. The fluorescence is quenched by the action of the infra-red at all points of the plate except at those points corresponding to the mark which are shielded so that the concealed design becomes visible. The paper 1 is held between the filter plate 6 and fluorescent plate 4. The design 11 to be compared is placed on a base 10 and illuminated by a lamp 12 and a semi-reflecting mirror 9 is provided so that the design 11 and the design 4 may be viewed as if superposed by the eye at 13. In an alternative embodiment, Fig. 5, a design on a sheet 1 is inserted between the baseplate 15 and an infra-red filter and is irradiated from an infra-red source 5. The infra-red shadow of the design is formed on the fluorescent plate 4 and illuminated from the same side by an ultra-violet lamp 7 forming, as in the previous embodiment, an image of the design to be compared visually with the design 11 on the base 10 by means of a semi-reflecting mirror 9. Details of a machine for performing this operation and a quick lighting system for lamp 12 are also given.

Abstract: 1,233,688. Filling containers; stopping articles on endless conveyers. H. J. HEINZ CO. 19 March, 1970 [8 May, 1969], No. 13398/70. Headings B8A and B8T. In a machine for filling cans with fluid, e.g. ketchup, under aseptic conditions, the cans are carried through an elongated chamber filled with steam in which the filling operation is carried out. The conveyer system, comprises link conveyer 10, 12, driven continuously by motor 21 via chain or sprocket system 20, 22 (Fig. 1). The cans are carried past a proximity switch 100 until they are stopped by star wheel 30, when six containers are aligned under six filling heads 50. The star wheel is held against counter clockwise rotation by pawl 36 acting in groove 35 of cam wheel 34 (Fig. 3) attached to the same spindle 31 as the star wheel. On completion of filling, relay 41 causes high pressure air to be admitted to cylinder 39 briefly pushing rod 40 outwards to disengage pawl 36 from groove 35, the rod 40 then returns, allowing the pawl 36 to engage cam 34. The star wheel rotates one revolution before the pawl again engages groove 35, thus permitting the six filled cans to pass along the conveyer. The completion of a revolution of the star wheel is detected by proximity switch 44 registering the passage of rod 43 attached to the cam 34. The filling system, comprises nozzles 54, filling valves 56 and level detectors 80, Fig. 6. The product flows from tank 71 via manifold 69 and pipes 68 to the filling heads 50. The flow is controlled by valves 56 actuated via valve stem 57 and rod 63 by means of a pneumatic piston and cylinder 65 which is controlled by relay 67. A biological seal is provided around valve stem 57 by pipe 59 into which high pressure steam is fed from pipe 60, the steam being removed via pipe 61. Electrical probes 80 detect when the containers have been filled. The probes 80 are attached to angle bar 78 and may be raised or lowered through chamber wall 8 by link work 85, 86, 88, and shaft 89. Shaft 89 may be oscillated by link work (90), (91), Fig. 7 (not shown), actuated by means of a pneumatic piston and cylinder (93) which is controlled by a relay (98). The position of the probes is detected by switches (96) and (97). The operating schedule.-Initially the filling valves are closed and the level probes are in their raised position. Cans are fed on the conveyer system past proximity switch 100 which will allow filling to commence after six cans have passed it. When six cans are positioned below the filling head the level probes are lowered and the filling valves opened. When the cans have been filled to the height of the level probe, the filling is stopped, when all the cans have been filled the level probes are lifted and the star wheel is released for rotation of one revolution, permitting the six cans to leave the filling station. When the star wheel has completed its rotation proximity switches 100, and 44 start the cycle over again.
