Title: Electrical Terminals and method of making the same
IPC: H01R12/55
Filed: 1966-08-08
Abstract: 1,159,390. Terminals. RITTER PFAUDLER CORP. 8 Aug., 1966 [12 Aug., 1965; 30 June, 1966], No. 35499/66. Heading H2E. [Also in Division H5] An electric device (e.g. a toaster, frying pan, coffee pot, warming oven or tray) having a thin film circuit (e.g. a heater) encapsulated in a dielectric layer comprising two superimposed coats includes a terminal comprising a wafer in contact with the circuit and a post which extends beyond the outer surface of the layer. As shown, each terminal is a nickel alloy disc 20 to which is welded a terminal post 19 in the form of a braided nickel or silver wire or a nickel rod. A dielectric layer of glass 14 is bonded directly on to a steel or aluminium plate 13 or to a ground coat 16 bonded to the plate which may, for example, be in the shape of a frying pan. A printed circuit 12 may constitute a heating element formed from a mixture of silver particles, binding cement and finely ground glass applied by a silk screen process is bonded to the glass. The terminals are placed on enlarged areas or islands of the printed circuit and an encapsulating glass coating 21 is applied and fused to the glass layer 14. The terminal discs may be attached to the islands by cementing. Each terminal disc is thin and its weight and rigidity are further reduced by a ring of circular apertures through it. This increases the grip between the glass and the disc, reduces the risk of rupture of the glass due to expansion of the disc and spreads the weight of the terminal to reduce sinking while the glass is in a fluent state. The disc may be domed (Fig. 8, not shown), at the centre and apertured in the domed region to allow any gas which may accumulate under the disc (e.g. from the adhesive) to escape through the apertures.

Abstract: 1,141,149. Corrugating; making bellows. C. R. HAIGH. 10 Aug., 1966, No. 35835/66. Headings B3A, B3E and B3V. A cylindrical metal element is grooved, e.g. to form a metal bellows expansion joint, by mounting the element on a rotatable workholder, positively rotating the work-holder, tightly gripping the rotating workpiece between a freely rotatable internal forming roll mounted on a forming head extending within the element and one or a pair of opposing freely rotatable complementary external forming rolls arranged outside the element, and applying pressure to the element by said internal and external forming rolls to form a peripheral convolution. The work-holder is then moved longitudinally of the rolls and the preceding steps are repeated to form successive corrugations on the element. A hollow cylindrical blank 10a is rotated by a chuck 44 vertically adjustable on posts 28 carried by a trolley 25. An annular groove is formed in the blank 10a by an internal freelyrotatable roll 100 co-operating with external freely-rotatable rolls 150a, 150b. The roll 100 is carried on a rod 82 moved laterally, to move the roll 100 towards the external rolls, by bell cranks 66, 68 swung down by draw bars 64 moved longitudinally by hydraulic means 60. The rolls 150a, 150b are supported by bellcranks 128, 129 swung upwardly by hydraulic means. The spacing of the rolls 150a, 150b is adjustable by hydraulic means 170; alternatively they may be replaced by a single grooved roll or a single multiple grooved roll. After the first corrugation has been formed the internal and external rolls are separated and the trolley 25 moved along to position the workpiece 10a for the formation of the next corrugation. After all the corrugations have been formed the workpiece is transferred to means which work harden and stretch the inner convolutions and which comprise an outer driven roll cooperating and moved towards two inner driven rolls. The outer convolutions may be work hardened by reversing the inner and outer rolls.

Abstract: 1396734 Freeze drying of aqueous extracts of vegetable products HAG AG 1 Aug 1972 [22 Oct 1971] 35893/72 Heading F4G In order to obtain a dark colour in freeze-dried granules of coffee extract as well as a bulk density between 200 and 250 gm/litre despite an initial extract concentration of more than 300 gm/litre, the liquid extract is foamed by adding nitrous oxide and/or argon and/or a halogenated fluorinated hydrocarbon gas prior to, or at the same time as, freezing the extract, and then the extract is freeze-dried. The liquid extract may be fed by a pump or gravity to a gas nozzle or valve in which the extract is mixed with the gas, and is mixed under pressure in a mixer so that as it leaves the mixture expands before being frozen. Instead, the liquid extract may be introduced with the gas into a scraper chiller under pressure so that the partially frozen extract expands as it leaves the chiller for subseqeunt freezing. Alternatively, the gas is introduced under pressure into the liquid extract, and stirred and cooled, and then frozen. Freezing may be carried out on a belt or roller, or in a plate or bowl, and takes 0À5 to 2 hours to reach - 45‹ C. The frozen extract is comminuted and graded. The hydrocarbon may be difluoromonochloromethane or trifluoromonobromomethane.
