Abstract: 854,753. Semi-conductor devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 1, 1957 [April 4, 1956], No. 10563/57. Class 37 In a semi-conductor device comprising a plurality of ohmic or rectifying contacts formed by a process of heating material containing donor or acceptor impurities in contact with a semiconductor body to dissolve the surface material, and then cooling to recrystallize impurity doped semi-conductor material on the body, only some of the contacts are connected to supply conductors. In one embodiment particles of aluminium are dropped on the pickled upper surface of an N type silicon wafer the lower face of which is nickel plated. The assembly is heated for 5 minutes at 780 ‹C. in an atmosphere of nitrogen or hydrogen and afterwards cooled. The upper surface is again pickled and a further nickel coating plated on the lower face before the wafer is broken up into small discs each carrying about 15 PN junction rectifying contacts to a selected one of which a conductor is attached. To form a transistor conductors are attached to two contacts spaced about 20 microns apart.

Abstract: 1,231,653. Glass melting. FORD MOTOR CO. Ltd. 21 June, 1968 [21 June, 1967], No. 29635/68. Heading C1M. [Also in Division F4] In a process for producing molten glass a temperature differential is produced along the longitudinal centre line of the melting chamber between a portion of the molten glass along that line and the molten glass on either side, the portion along the line being at a lower temperature than its surroundings, whereby unmelted batch is maintained away from the side walls of the melting chamber. In a preferred embodiment, a stainless steel hair-pin shaped water-cooled element 36 is positioned through the end wall of the melting chamber along the longitudinal centre-line thereof to dip into the molten glass 44 at the region where all batch is substantially melted. Batch is fed in two streams from hoppers 34 one on each side of element 36. By cooling a portion of the molten glass surface downward convection currents 58, 60 are set up which cause unmolten batch 48c to flow in towards the centre of the furnace away from the end walls. In an alternative embodiment, a baffle (62) (Fig. 4, not shown) is positioned along the longitudinal centre-line between the end wall and the shadow wall 24 proximate the glass surface. The molten glass immediately beneath the baffle is thus shielded from the heat and the desired temperature differential and convection currents are set up.

Abstract: 1,232,707. Refrigerating. H. STIERLIN. 21 May, 1968 [26 May, 1967], No. 24247/68. Heading F4H. In an absorption system using inert gas, vapour from the generator 96 exchanges heat with the liquid heat exchanger above the liquid level 36 in the absorber vessel 13, the latter being connected to a vessel 123 on the suction side of the thermosyphonic pump so as to permit solution concentration balancing between the vessels. Vapour and liquid from lift tube 97 in the generator pass downwardly through spaces 99 and 101 respectively. The vapour then passes through coils 111, 113 and tube 2 to the condenser and the liquid through coils 105, 107 and tube 109 to the absorber 15. Solution is constrained by a barrier 115 to leave the absorber through tube 117 which communicates with a coil 119 interposed between coils 107, 113. Coil 119 discharges to coil 111 and flows to vessel 123 in countercurrent to the ascending vapour. The absorber vessel 13 may be elongated horizontally and an accumulator vessel may be included in line 109, line 117 or in parallel with the absorber (Figs. 4 to 6, not shown). Vessels 123 and 13 may be connected by coaxial tubes and circulation between the vessels promoted by supplying solution to the generator from vessel 13 instead of, or in addition to, vessel 123 (Figs. 7 to 10, not shown).

Abstract: 1,234,350. Odometer drives. FORD MOTOR CO. Ltd. 30 Dec., 1969, No. 63209/69. Heading B7H. [Also in Division F2] A motor vehicle including an auxiliary gearbox 5 which is operable to disconnect the drive to the rear wheels and to connect the output from a change-speed transmission 1 to a power take-off shaft 15, e.g. for driving a vehiclemounted cement mixer, and an odometer 19 drivable from the transmission 1, is provided with an isolator device 23 (Fig. 2) in the drive line to the odometer whereby, when the drive is connected to the power take-off shaft, the odometer is disconnected from the transmission 1. The isolator device includes an input ring gear 31, an output shaft 35 and a planetary gearset comprising sun-gear 39 on shaft 35 and planet carrier 37 rotatable on shaft 35 and carrying planet gears 36 meshing with ring and sun-gears 31, 39. The sun-gear carries a clutch plate 4 fixed to shaft 35 and having a tab 45 interengageable with a tab 43 on the planet carrier, and is axially slidable on shaft 35 under the influence of a solenoid 49 which is actuable by a switch 51 adjacent control lever 17 of the auxiliary bear-box 5. In the position shown in Fig. 2, in which the drive is connected to the rear wheels, the odometer 19 is driven via shaft 35 of the isolator device since the clutch plate 41 and ring gear 31 are locked together by interengagement of the tabs 45, 43. When the auxiliary gear box is operated to connect the drive from transmission 1 to the power take-off shaft 15, solenoid 49 is energized and causes the clutch plate 41 and sun-gear 39 to move axially to the left (as in Fig. 2) whereby the tabs disengage and the sun-gear is held against rotation. As a result the shaft 35 does not receive any drive from the ring gear 31. Where the rear axle is a two-speed axle, change of ratio in the axle is compensated for in the drive line to the odometer by a device 53. This device (Fig. 4, not shown) is similar to the isolator device but differs in that: (a) the planet carrier is splined to the output shaft, and (b) the sun gear and clutch plate are rotatable on said shaft. Hence, while the output shaft will be driven in both axial positions of the sun-gear and clutch plate, the ratio of the drive input to output will differ at these positions since, in one instance, the sun gear is rotatable with the planet carrier due to interengagement of the tabs and, in the other instance the sun gear is locked against rotation due to energization of the solenoid, the latter being energized in dependence upon the rear axle ratio selected.

Abstract: 1,250,720. Suppressing waveguide modes. WESTERN ELECTRIC CO. Inc. 27 March, 1969 [29 March, 1968], No. 15999/69. Heading H1W. Unwanted waveguide modes are suppressed by means of a suitably positioned dielectric resonator which is associated with a dissipative element. The resonator 16 may consist of a cylinder 11 of TiO 2  dimensioned to resonate at an appropriate frequency in a TE mode. Such a mode is excited when the resonator is placed in an R.F. magnetic field coincident with its axis. Thus, a resonator 16 placed as shown in a rectangular waveguide 15 will couple to the TE 30  mode, which it is desired to suppress, but not to the fundamental TE 10  mode. Energy thus coupled to the resonator is dissipated in a resistive element which may consist of an annular film 12 of tantalum having a resistance equal to the characteristic impedance of the selected mode. A number of such resonators may be distributed at appropriate positions in the same transverse plane. They may be imbedded in a support member made of a material of low dielectric constant. Figs. 4, 5 (not shown) illustrate arrangements for suppressing: (a) the TE 20  mode, (b) the orthogonal TE 03  and TE 30  modes in a square guide.
