Abstract: 1,192,945. Superplastic fine grained alloy. INTERNATIONAL NICKEL Ltd. June 9, 1967 [June 30, 1966], No.26777/67. Heading C7A. A wrought nickel-chromium alloy having an ultrafine gamma-alpha microstructure and containing no more than 2% of other phases such as carbide, eta, laves and carbonitride phases, comprises:- Ni 9%- # at least 19% Co up to 10% # at least 19% Cr up to 55% such that at least 2% is not dissolved in the matrix at 980‹ C., but not exceeding the percentage determined by the relationship % Cr = 68À9 - 0À435 (% Ni) Fe 0-55% Ti 0-2À5% Mg 0-0À1% Zr 0-0À1% Ca 0-0À05% B 0-0À015% and optionally, in a total amount of not more than 7%, C 0-0À1% Mo 0-3% # % Mo +%W/2 = 0-3% W 0-1À5%# Al 0À1-5% % Al + % Ti not over 3À5% Nb 0-2À5% #Nb + % 2 Ta /2=   0-2À5%  Ta 0-4% # Cu 0-3% Be 0-1% Si 0-0À5% Mn 0-0À5% V 0-0À2% These alloys exhibit superplasticity if the alpha phase is present from 2-70% and the size of the gamma grains is preferably not more than 3 microns. The alloys may be welded using a matching filler wire. To produce the required microstructure the a phase is caused to precipitate in the alloy which has been plastically deformed in the two phase region, during or after recrystallization. The alloy may also be heated in the two phase region to complete the precipitation and recrystallization. Suitable treatments are:- (1) hot working at 1205‹ C. down to 980‹ C. heating to 980‹ C. during 30 minutes and holding for 20 minutes, and (2) solution treating, quenching in water, cold-working 50%, ageing at 595‹ C. for 16 hours and heating to 980‹ C. during 30 minutes and holding for 20 minutes. Certain alloys within the above range are said to be novel.

Title: Accelerometer
IPC: G01P15/13
Filed: 1965-06-24
Abstract: 1,070,614. Accelerometers. NORTH AMERICAN AVIATION, Inc. June 24, 1965 [July 2, 1964], No.26877/65. Heading G1N. An accelerometer includes a proof mass 71 cantilevered from a base member 72 which is itself cantilevered in the opposite direction from a support. The proof mass, which is of insulating material, carries concentric conductive portions 86, 87 on each face, connected to conductive portions such as 87a on the base member. Coil assemblies 50, 60 are mounted on opposite sides of proof mass 71 by means of a conductive bolt 54 which connects the coils in series. One end of each coil is connected through the adjacent conductive region 87 and the corresponding region 87a to external terminals. On each side of the proof mass lies an electrically conductive magnetic member 30, 40, each consisting of a cylindrical core part 31, 41, a permanent magnet 36, 46 and a polepiece 37, 47, defining an annular air gap within which the corresponding coil assembly 50, 60 lies. Clamped between flanges 33, 43 and base member 72 are substantially semicircular shims 39, 49, the ends of which lie on a line A n  passing to one side of the centre of the proof mass so that equal portions of conductive regions 86, 87 lie on each side of line A n . The left hand portion of base member 72 is thus clamped and the right hand portion is cantilevered about line A n . In normal operation under vertical acceleration the proof mass 71 pivots about region 73, 83 and the capacitances between flange 33 and region 86 and between flange 43 and region 76, on the other side of disc 71, vary and unbalance a bridge circuit. The unbalance signal is detected and used to vary the direct current flowing in coils 52, 62 to restore the proof mass towards its undeflected position. If horizontal accelerations are present distortion of the base member 72 is confined to pivoting about line A n  which has no effect on the capacitances between flanges 33, 43 and regions 76, 86.

Abstract: 446,168. Automatic control systems. MOUNT, S. C., 43, Bloomsbury Square, GRIERSON, R., 4, Bloomsbury Place, and CRITTALL & CO., R., Ltd., 43, Bloomsbury Square, both in London. Sept. 19, 1934, No. 26906. [Class 38 (iv)] Temperature.-In a system for maintaining a room or building at a predetermined temperature during certain times, with or without control to another temperature at other times, a series of outdoor thermostats or an equivalent multiple thermostat is used in association with a switch driven by a clock, preferably a synchronous clock, so that whatever be the outside temperature the desired temperature is always attained at the same hour. The outdoor thermostats are connected in a circuit K in series with the room or other thermostat controlling the heating apparatus. The arm a<1> of the clock switch is shown at 6 p.m., at the end of the period of normal or " high " temperature regulation, when leaving the contact in connection with the outside thermostat J, which is set to close at 55‹. This may or may not cause the heating apparatus to regulate at a " low " temperature. If the outside temperature be lower than 30‹ at 2 a.m., the circuit through the thermostat B will then be closed and the heating system will then be put in normal or " high " temperature operation. Similarly operation will be started at a later period should the outside temperature be such that certain of the thermostats B ... J are not closed when the clock contact engages the contact connected to such thermostat.

Patent GB-305961-A (GB)
Title: Improvements in dipping and swivelling mechanism for vehicle head and like lights
IPC: B60Q1/124
Filed: 1927-10-12
Abstract: 305,961. Treglown, G. H., and Barnfather, E. Oct. 12, 1927. Vehicle lamps, directing.-In a lamp dipping and swivelling mechanism for vehicle and like headlights, a projection on the swivel mounting is engaged by a stop when the lamp is dipped, thus causing the lamp to be swivelled at the same time. In the construction shown, the lamp support a is carried by a swivel mounting comprising a disc b and depending stem c mounted in ball bearings on a sleeve m secured on a transverse rock-shalt f supported in bearings g. The lower end of the stem c is slotted and engaged by a. spring n, which is non-rotatably mounted in a cap o and serves to turn the lamp to the normal position, in which it is arrested by a stop q which engages a projection p on the disc b. The swivelling of one of the lamps during dipping is caused by a second projection s which engages a stop consisting of a screw t in a lug u on the bearing g. The screw stop t may be employed in connection with either lamp, according to the rule of the road, the off-side lamp not being swivelled. The lamps may also be automatically swivelled in accordance with the steering by means of a shaft v, which is connected to the rock shaft of the steering-gear so as to turn with it and carries two helical cams 1 engaging stubs 3 on arms 2 on the discs b. The cams are so disposed that only the one situated at the side to which the vehicle is being turned engages the corresponding stud 3, so that a left-hand turn causes the left-hand lamp to swivel to the left and a right-hand turn causes the right-hand lamp to swivel to the right. During daylight, the lamps may be dipped sufficiently to move the studs out of range of the cams 1, so that the lamps are not affected by the steering. Alternatively, the lamps may be swivelled during steering by means of a reciprocating transverse rod provided with a pin movable, radially in a slot in a bevel gear meshing with a bevel gear segment freely mounted on the rock shaft and connected by a rod with the steering gear. Specification 303,849 is referred to.

Title: Improvements in or relating to television transmitting systems
IPC: H01J31/34
Filed: 1934-09-20
Abstract: 446,664. Cathode-ray tubes. McGEE, J. D., 9, King's Avenue, Ealing, London. Sept. 20, 1934, No. 27120. [Class 39 (i)] Television-transmitting apparatus comprises a cathode-ray tube containing successively an electron gun 5, a grid 7 and a mosaic screen 8 on which an electrostatic image of the object to be transmitted is formed, and the grid 7 is maintained at approximately the potential of the cathode 3 of the gun 5. As shown, the mosaic 8 is of the type having photo-electric elements insulated from each other and from a signal plate, the electrostatic image being formed by projecting an optical image of the object to be transmitted on to the side of the screen scanned by the ray. The signal plate and the photo-electric elements are normally at earth potential, the cathode 3 being earthed directly and the signal plate being earthed through the output resistance 18. The grid 7 is connected to the signal plate through resistances 15, 17 and a small battery 16 which biasses the grid slightly negatively to compensate for the initial velocities of electrons emerging from the cathode 3. When no light falls on the photo-electric elements the ray does not reach them ; on exposure to light, they emit saturated photo-electron currents and become slightly positive and the cathode ray then reaches them and restores them to earth potential, but the velocity of the cathode ray striking them is insufficient to liberate secondary electrons. The apertures of the grid 7 are equal in width to the spacing between the grid 7 and the mosaic 8 and are also equal to the width of the ray at the grid. A further grid 19 may be maintained positive so that the deceleration of the ray occurs near the grid 7. In modifications, the grid 7 may be used with mosaics of the type having the optical image projected on to the side opposite to that scanned by the ray, the signal plate being perforated and insulated to receive photo-electric elements in the perforations, or of the type in which mosaic elements in a perforated signal plate scanned by the ray have their potential controlled by an electron image projected from a separate photo-electric screen. Specifications 442,666 and 446,661 are referred to.

Abstract: 417,627. Valve amplifying and detecting circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. Oct. 4, 1933, No. 27333. Convention date, Oct. 4, 1932. [Class 40 (v).] A receiving or amplifying circuit comprises a valve "in retarding field connection," e.g. a valve operating on the Barkhauzen-Kurz principle, inserted at a current loop in the associated resonance circuit, damping due to the low resistance of the valve being reduced by back-coupling the output to the input circuit. Fig. 1 shows a detector circuit in which the anode-cathode path (input) is inserted at a current loop in a series-tuned aerial circuit L1, C1, the output circuit comprising resistance Rg shunted by condenser C2 being back coupled by coil L2 to the input. The anode is suitably biassed over choke D and the input resistance of the valve may be shunted by a capacity to reduce the damping of the aerial circuit. The valves of a multistage amplifying and detecting. circuit may each be coupled to their input circuits in a similar manner, and back-coupling may be effected across a number of stages. The Specification as open to inspection under Sect. 91 comprises also the arrangement shown in Fig. 1 (Cancelled) in which the valve B is inserted at a current loop in the tuned input circuit L1, L11, C. This subject-matter does not appear in the Specification as accepted.
