Title: Improvements in and relating to the amplification of electrical variations
IPC: H04B1/16
Filed: 1920-07-07
Abstract: 147,149. British Thomson - Houston Co., (Assignees of Hull, A. W.). Nov. 8, 1915, [Convention date]. Void [Published under Sect. 91 of the Act]. Thermionic relays.- Electric variations to be amplified are applied to a " negative resistance " and an ordinary resistance in parallel, much greater current variations being thereby produced in each of the resistances. As shown in Fig. 1, the negative resistance comprises a vacuum tube 2 having a tungsten-filament cathode 6, an anode 9 of grid form, and a third electrode 11 consisting of a metal cylinder. A battery 4 impresses a constant positive potential on the anode 9 relatively to the cathode 6. Connexion is made from the third electrode 11 through the positive resistance 1 to an intermediate point on the battery. The potential imparted to the third electrode is such that an increase therein causes a decrease of current through the valve. A photo-electric tube 3, having a cathode of potassium or the like, is connected across both resistances, but may be replaced by the secondary of a transformer, having its primary in a telephone or other circuit., A device 14 for measuring or utilizing the magnified current or potential variations is connected in series or in parallel with the positive resistance.

Title: Improvements in or relating to cap feeds for bottle capping machines
IPC: B67B3/064
Filed: 1951-08-15
Abstract: 698,645. Feeding bottle &c. caps. POCOCK, A. G., and KIRK, C. R. July 31, 1952 [Aug. 15, 1951; April 18, 1952], Nos. 19267/51 and 9836/52. Class 125(ii) [Also in Group II] In apparatus for supplying caps from a magazine 1 to a shoot 2 from the bottom of which they are abstracted by passing bottles B or the like, the passage of a bottle triggers suction means for extracting a cap for the next succeeding bottle and the end of the shoot is provided with means to regulate the passage of caps. As shown in Fig. 1 (19267/51) a bottle.draws a cap C from the shoot, the cap being smoothed over or wiped by a plate 25, the pivot 26 of which forms a normally vented valve which prevents the'creation of suction in a chamber 4 by a source 21. When pivoted, the flap closes the vents and a vacuum is formed in chamber 4 and is transmitted through the clearance between a valve element 13, 15 and a piston 6 and suction tube 7. The end-most cap in the magazine is normally abutted by an open-ended casing 8 and by a spring 10, and the suction first bows it in to abut the end of tube 7 and the piston is then retracted by the suction against a spring 9 until valve element 13, 15 seals against the piston 6. The suction in tube 7 and casing 8 is then destroyed by air entering through apertures therein, the cap falls into the shoot 2 and the piston is returned by spring 9 to abut the next cap. A handoperated valve may_ be provided in the pneumatic system to enable the manual feed of caps by the operation of a push-button type venting valve. As shown in Figs. 3 and 5 (9836/52), the wiping flap 4 is pivoted to the cap shoot 1 having protections 2 for retaining the lowest cap. When the flap 4 is pivoted by a bottle, lugs 5 enter the shoot to prevent descent of the cap next to the one being abstracted. Working in a slot 4<SP>1</SP> in the flap is a part 9 pivoted at 10 and so shaped and weighted that when the flap 4 is pendent, a nose 9<SP>1</SP> stops the caps from jumping past the projections 2 due to their momentum and that, when a cap is being laid on the bottle, it is steadied. The flap 4 is retarded by a spring 7 so that it does not bounce and has an arcuate trailing edge which mates with the leading edge of a smoothing plate 11.

Filed: 1971-04-19
Abstract: 1351867 Semi-conductor devices GENERAL ELECTRIC CO 19 April 1971 [26 Jan 1970] 20350/71 Heading H1K A semi-conductor device includes a layer having a reverse graded net impurity concentration i.e. the concentration at a surface of the layer is less than that within the layer. The layer may form the gate controlled base layer of a thyristor, in which case the junction between it and the adjacent emitter layer has the highest reverse voltage blocking capability of any junction in the device. The layer may alternatively form the gate controlled base layer of a gate turn off thyristor, since its series resistance, in the vicinity of its junction with the other base layer, is low. Using the layer as a base layer in a transistor results in improved gain at low currents. Finally it may be employed as a barrier interface layer between the metal and remainder of the semi-conductive material in a Schottky barrier diode. Here it reduces the forward conduction drop at low current densities, while retaining the reverse voltage blocking capacity of a uniformly high resistivity layer. The layer may be formed epitaxially, the deposited material including a suitable amount of dopant to achieve the desired impurity profile. Alternatively a source substrate including an impurity with a desired profile, achieved by diffusion, may be used, the source and device substrate being heated together, the source to a higher temperature, whereupon on the introduction of iodine vapour the source material including the dopant is transferred to the device substrate, so that a doping profile which is a mirror image of that of the source may be achieved in the layer.
