Title: Improvements in prepayment type electric supply meters
IPC: G07F15/00
Filed: 1935-11-11
Abstract: 465,492. Prepayment mechanism for meters. ENGLISH ELECTRIC CO., Ltd., and TILSTONE, G. Nov. 11, 1935, No. 31161. [Class 27] In a prepayment electricity meter, the force opposing the closing movement of a switch operating member increases abruptly at the end of the closing movement to a value considerably greater than over the initial and greater part of such movement, the additional force serving, for example, to overcome any tendency of the switch to stick during opening. The invention is described as applied to the switch mechanism described in Specification 449,556 in which a heavy member 13, loose on the switch operating shaft 15, is raised into engagement with a latch 17 during prepayment, and, by a pin-andslot connection 13b, 14a, turns an arm 14 secured to the shaft 15 to close the switch contacts. The invention provides a spring- biassed pivoted arm 1, normally resting against a stop (not shown), which arm is engaged by the switch operating arm 14 at the end of the closing movement. The arm 1 serves to apply an additional opening force to the switch arm 14 when released, and also ensures that the lostmotion connection 13b, 14a is taken up so that the heavy member 13 is effective to apply a switch opening impulse as described in Specification 449,674. Moreover, when the mechanism is such, as described in Specification 449,675, that the switch parts are returned slightly from the fully closed position before being held by the latch 17, in order that each time a coin is inserted the coin mechanism may impart a slight oscillating cleaning movement to the switch contacts when they are already closed, the spring-actuated arm 1 ensures this slight return movement.

Abstract: 136,818. Norske Aktieselskab for Elektrokemisk Industri Norsk Industri- Hypotekbank. Dec. 16, 1918, [Convention date]. Slag, treatment of.-Water, with or without steam or other gases, is poured or forced into or upon molten slag so as to form a foam sufficiently liquid to be poured into moulds in which it is cooled so as to form porous bricks or insulating- material. The product may be crushed and used as a filling for walls and the like. In an example, slag is heated in an electric furnace to a temperature of 1400‹ C. and poured in a continuous stream into a container lined with refractory material through an inlet formed in the lower part of the container. Above this inlet, one or more tuyeres are provided, through which water is admitted, preferably under pressure, when the slag is on a level with or above the tuyeres. The water is added in a continuous stream and is intimately mixed by means of a rotary strirrer mounted in the container, the stirrer being so constructed as to prevent an accumulation of solid slag on the tuyeres. The supply of water is regulated so that the temperature of the foam will be about 1000‹ C. At this temperature, it is liquid and may be led through an overflow into moulds.

Title: Controlling high frequency signals

Filed: 1975-07-28
Abstract: 1500440 Semi-conductor devices INTERNATIONAL BUSINESS MACHINES CORP 28 July 1975 [14 Aug 1974] 31436/75 Heading H1K A signal of higher frequency than the relaxation frequency in a semi-conductor layer 1 is propagated along the layer 1 between pairs of input and output terminals 7, 8 and 11, 12 and is subjected to modulation with respect to transit time, frequency, amplitude and/or phase by control means which modulate the conductivity of the layer 1 using a control frequency lower than the relaxation frequency. Control may be effected by exposure to light or by the application of a control signal between appropriately located control terminals. In Fig. 2 the control terminals 15, 16 are connected respectively to a conductive layer 2 on the Si substrate 1 and to an Al strip 4 capacitively coupled to the substrate through SiO 2  layer 3, facilitating control by field effect. The input and output terminals are connected to the strip 4 and layer 2 at opposite ends of the substrate 1. In a modification the strip 4 is divided into spaced, independently addressable sections (25-29), Fig. 5 (not shown). In Fig. 3 conductivity modulation is achieved by the provision of spaced P<SP>+</SP> zones 24 forming PN junctions with the N- substrate 1, control terminals 22, 23 being connected to all of the zones 24 and to all of the intervening areas of substrate 1 respectively. The modulating device of the invention may be integrated with a Gunn oscillator to provide the high frequency input.

Abstract: 1376966 Turbines; seals GENERAL MOTORS CORP 6 July 1972 [18 Oct 1971]  31709/72 Heading F1T [Also in Division F2] A porous gas cooled seal comprises a laminated structure 22 of sheets bonded together, a first group 32 adjacent the seal face 30 consisting of abradable sheets 34, e.g. of thoria dispersed nickel-chrome alloy, each having a pattern of pits 40, 42 etched into its respective faces and overlapping to form openings 43. The successive sheets 34 provide an array of inclined passages for flow of coolant air, as indicated by arrow 47, the air discharging approximately tangential to face 30 even in the event of substantial abrasion of the latter. To group 32 is bonded a second group 35 having a metering function and of less porosity than abradable group 32. Group 35 comprises three sheets 36 having an array of bosses 41 and holes 45, the latter being out of register in adjacent sheets, together with a distributing sheet 37 having elongated grooves 56 etched in one face and intersecting circular pits 57 etched in the other face. Grooves 56 are in register with the pits 42 of the adjacent sheet 34. A further group 38 consisting of sheets 39 with through-holes 62 provides structural reinforcement for the groups 32, 35. The seal structure 22 may form a segmental stator shroud surrounding the tips of turbine rotor blades (11), Fig. 1 (not shown) the structure being bonded to an upstream ring 14, Fig. 3, and a corresponding downstream ring (15) which engage flanges on the turbine casing (2). Cooling air is supplied to a chamber (20) outwardly of seal 22 from whence some of the air-flows through the latter to seal face 30 where it discharges in the direction of rotation of the blades (11). The remaining air discharges from chamber (20) through inclined holes 23, 24 in seal 22 and ring 14 respectively. The rotor blades may carry a tip shroud (68), Fig. 8 (not shown) having ribs (71) co-operating with seal 22 or, alternatively, a rib (67), Fig. 7 (not shown) may be formed by an extension of the concave wall (63) on each  blade. The seal may also be employed to seal an axial rather than a radial gap and may be the inner member of a radial gap rather than the outer member as shown.

[Classes 8 (i) and 102 (i)] [See also Group XXXIII] A reciprocating blade impeller is formed with a number of blades pivotally mounted on radial axes, the blade members being reciprocated within a tube. Blades 1 are mounted on a vertical axis 2 attached to a reciprocating shaft 5. The blades are surrounded by casing 3 which moves with the shaft in a tube 4 and this casing carries an obstruction bar whereby in the feathered position of the blades they are held slightly open. In the working position the blades have their outer edges in close contact with the casing 3 and to assist in this the shaft may have resilient members tending to urge the blades to the open position. The after surfaces of the blades are shaped so that the section is semi-elliptical and whereby and in the feathered position resistance to the passage of the air or water is reduced. In the place of two blades a number of pairs of blades may be used of sector form, each pair being on a radial axis. In a modification the casing 3 may be omitted and the blades allowed to contact with the main tube 4 and in this case the blade tips may be provided with rollers 7. Also a number of resilient rods 8 carried from a cross shaft 9 are used to urge the blades to the operative position. The cross shaft 9 can be guided by a sleeve outside the casing, the main trunk being slotted at 10 for this purpose.
