Title: Method of Fabricating a Metallic Pattern on a Substrate
IPC: G11B5/31
Filed: 1981-12-02
Abstract: A method for fabricating a metallic pattern (6) eg of Ni-Fe alloy on a substrate (1) eg of SiO2 or glass consists of depositing an adhesive metal layer (2) and/or, plateable metal layer (3) which become(s) cathodic during etching, on a substrate. A narrow self-supporting border of photoresist (15, 16) is then applied. An anodic layer (4, 5 and 6) is then deposited and the photoresist removed. The adhesive and plateable metal material is etched in those areas (11, 12) previously covered by the photoresist and fresh photoresist (8) applied to encapsulate those areas (6) of the anodic layer which form the final pattern of interest. The unwanted anodic material (4 and 5) is then etched and the photoresist removed. The adhesive metal (2) may be Cr, Ti, Ta, W, Nb, V or Zr; and the plateable metal (3) may be Au, Pt, Pd, Cu, Ni or Ni-Fe. The invention overcomes the problem of severe undercutting of the cathodic layers (2 and 3). <IMAGE>

Title: Control System for a Drink Merchandising Machine
IPC: G07F9/02
Filed: 1982-01-18
Abstract: A cold drink vendor has a programmed microcomputer which controls the drink dispensing procedures and which can be set to vary drink size, amount of ice to be dispensed, carbonation levels of each selection and the mix of the syrup and water for each selection. This is based on a constant flow rate variable time method of dispensing the beverage. Initially switch banks set by a service person are interrogated to determine the size of the drink and amount of ice to be dispensed, and the time cycle to dispence the drink is adjusted accordingly. Upon the establishment of credit and the actuation of a selection switch, additional switchbanks are interrogated to determine whether the beverage selected is high carbonated, low carbonated or non-carbonated. It determines when to start the corresponding syrup pump, in accordance with the syrup viscosity, and the drink is dispensed. <IMAGE>

Title: Coating applicator
Inventor: DENTON NORMAN
IPC: B05C3/12
Filed: 1984-02-10
Abstract: An applicator for coating optical fibres directly after drawing includes a chamber (17) for containing coating material and a flexible orifice element (19) through which the fibre (8) is pulled and which serves to ensure that there is a thin coating of the coating material on the fibre. The coating thickness can be varied during drawing by varying the compression of a compressible ring (21) and thus varying the internal diameter dimension of the orifice element (19). The coating thickness can thus be controlled, throughout the duration of a pull of an optical fibre preform into an optical fibre, by an automatic feedback process. Predetermined variations in coating thickness can also be achieved. <IMAGE>
