Articles, such as filled ice-cream cups C, advancing along a horizontal path, are collected into rows of stacks by stopping a first article until a row accumulates, lifting this row to allow another row to accumulate beneath it, and repeating this until a sufficient stack has developed. The array of cups is then discharged into a packing box B, Fig. 3. As shown, the array consists of two rows of three cups, four cups high, all handled upside-down. The cups are collated, in pairs, on belt-conveyers 22 having been placed there from depositor 23. The cups are stopped to provide accumulated single-file rows by gates as 28, Fig. 3, their number being counted by a finger (30, Fig. 5, not shown). When the rows are full, the cups are lifted by rising webs 34, Fig. 4, and retained in the lifted position by support gates 31, 32. When the stacks -are full, the whole array is pushed by pusher 40 into box B on converging guides 41, and when full, the box slides down ramp 43. The machine is pneumatically operated to facilitate washing down, the mechanism being described in detail.

Abstract: 1,244,624. Programmed control of machine tools. GENERAL ELECTRIC CO. Oct. 29, 1968 [Nov. 21, 1967], No. 51293/68. Heading G3N. An on-machine inspection system, for cooperation with a machine member controlled in response to coded input data, comprises a probe, positioned according to commanded data and then brought to a null position, to derive an output representative of deviation from the commanded position which is stored. As shown, a known numerical control system for a machine tool comprises a tape input 18 feeding a control 14, wherein error between a programmed and an actual position is determined and through a command phase counter 13 and resolver feedback control 20 to a discriminator and digital to analogue converter 21 providing an analogue position signal to a servo-drive 23 for a machine part. The known system is modified to enable on-machine inspection by the addition of an inspection and control system 30 and a switching arrangement 31. Machine inspection is initiated by a block of data from tape input 18 calling for insertion of a probe 40 in a tool position and selection of the mode of operation in circuit 45. The probe is moved under control of the command data to the programmed position by the discriminator 21 and thereafter in response to probe deflection by a circuit 31. Count control circuits 17, 43 develop a digital value, representing the phase difference of the actual position from the commanded position, which controls the command phase counter 13 and is fed to a deviation counter 46. The information in the deviation counter is used, in dependence on the programmed operating mode, for 1) a display in unit 50 2) a read-out by a printer 49 in dependence on limit values set by programme unit 47 and comparator 48 3) re-machining when it is fed to a store 51. The store 51, containing the offset deviations, is called up by programmed data from unit 18 during re-machining through a machining situation de-coding circuit 52 and a tool and offset control 53. The offset values from store 51 are fed through a gate 54, whereby manually set-in probe offsets from a unit 55 are added, to pre-set a data transfer counter 44 controlling the counting of pulses into position control 14.

Abstract: 1,162,410. Coating by vapour deposition. JONES & LAUGHLIN STEEL CORP. Nov. 22, 1967 [Nov.23, 1966], No.53259/67. Heading C7F. Entrainment of liquid metal in metal vapour evaporated from a heated crucible 12 is minimized by incorporating in the crucible 12 vertical projections 6 extending upwards from its floor, the projections and the crucible being of a material which conducts heat but is not wetted by liquid metal contained in the crucible during evaporation. In use gaps 8 are present between the molten metal and the walls of the crucible, and between the molten metal and the projections 6. Metal vapour bubbles 7 originating on the crucible floor are likely to reach the surface of the metal at a gap 8 rather than at the small area of upper surface 13, whereas without the projections 6 they would rise to the surface 13 through the full depth of the molten metal, growing on the way and eventually bursting at the surface and causing splashing. The metal evaporated may be Zn, and be deposited on a moving strip 2. Both crucible 12 and the projections 6 may be of graphite.

Title: Improvements in or relating to the production of workpieces by moulding
IPC: B22C7/00
Filed: 1967-09-27
Abstract: 1,249,973. Making dies; forging; casting. MOLINS MACHINE CO. Ltd. and P. H. C. WADDINGTON. 25 Sept., 1968 [27 Sept., 1967; 23 Nov., 1967], No. 43952/67 and 53410/67. Headings B3A, B3F and B3H. A die or mould in which a metal article can be cast or which can be used to forge a metal article is made by forming a model of the article using a set of similarly shaped blocks and using the model to form the die cavity. The blocks may be of rectangular, square, triangular or hexagonal cross-section and have different lengths. They are made of wood or plastics held together by adhesive. Alternatively they may be ferromagnetic or wood or plastics with internal magnets so that they are magnetically held together. The model is larger than the article. The model is assembled by placing a transparent sheet with grid markings over a drawing of the article and assembling blocks to correspond to the grid squares containing the article. This procedure is repeated in three mutually perpendicular planes. The details of the model obtained from the grids may be transmitted to a remote model assembler by teleprinter. Alternatively the grid data could be translated into a programme for an automatic model assembling machine. If a more accurate model is required smaller blocks can be used at the outer surface of a smaller size. The model is used to form a cavity in sand for sandcasting or shell moulding. Alternatively the model is coated with material to form an intermediate mould which is stripped from the model and used to form a metal model by casting. The metal model then has the forging die cast around it. The workpiece may have pretapped inserts which are placed in position in the mould before casting. In the case of forging the die may have projecting pins to form bores in the workpiece which are tapped after forging. After casting or forging the excess metal is machined off.

Filed: 1975-01-08
Abstract: 1506158 Manufacture of photovoltaic cells PHOTON POWER Inc 8 Jan 1975 [8 Jan 1974] 54261/74 Heading H1K In fabricating a photovoltaic cell a microcrystalline layer is formed on the electrically conductive surface of a rigid non-conductive substrate by a spraying process preformed with the surface maintained at a uniform temperature by supply of heat from a hot fluid medium. The described cell is based on a sodalime glass substrate, consists of successive layers of tin oxide, cadmium sulphide, copper sulphide, copper oxide and copper and is preferably formed in a continuous process at the output end of a float glass manufacturing plant. The temperature of the glass is then gradually reduced as it passes through the following essential deposition and annealing stages, its temperature being maintained in each deposit or step by contact with a molten metal bath over which it runs. After optionally treating the glass with H2SiF6 at 520 F. to form a sodium ion barrier of silica, it is coated with 0À4Á of tin oxide while held at 950 F. in air by spraying with a mixture of tin dichloride, phenylhydrazine hydrochloride and ammonium fluoride in methanol, and after annealing to 700 F. is coated with 2Á of cadmium sulphide from a solution of cadmium chloride, aluminium chloride, and N,N-dimethylthiourea or thiourea in water from one or more spray nozzles traversing the moving glass strip. After further annealing to 300 F. a copper sulphide layer 1000 thick is formed by similarly spraying with a solution of copper acetate and N,N-dimethylthiourea, and then a 500 A thick copper sulphate layer. The coated strip is next cut into sheets, and an acid resist applied to leave exposed a rectangular grid which is etched down to the tin oxide layer and recoated by evaporation of INCONEL (R.T.M.) or chromium, and then aluminium. Finally copper, optionally overcoated with aluminium. is deposited by evaporation on the copper sulphate layer, heated to 500 F. to form cuprous oxide between it and the sulphate and then slowly cooled. In one alternative method, in which the copper sulphate is deposited directly on the CdS this heating also reacts the abutting layers to produce a copper sulphide film between them, while in another copper sulphide is deposited by evaporation. In another variant using a grid electrode of zinc this is deposited on the copper sulphide, or on the CdS which is then coated with lacquer during deposition of the copper sulphide and subsequently diffuses down to the tin oxide. The rate at which the sulphide layers can be deposited can be greatly increased without production of undesired thermal stresses by using rotating bell-type electrostatic atomizers rather than nozzles for spraying. The quality of the CdS may be improved by holding two layers thereof together while heating at 950 F. Specifications 1,506,160 and 1,506,159 containing the same disclosure are referred to.
