The alloy composition comprises 50%-99% Ti and 50%-1% of one or more of the following metals: Be, Al, Sn, Cu, V, Cr, Mn, Fe, Co, Ni, Zr, Nb, Mo, W, Ta, Hf, Re.  It may also contain 0.5%-10% of Th, Pd, Pt, Ce and La.  The a Ti powder with a particle size of -30 + 200 mesh (Tyler) should have a maximum hardness of 200 BHN, and the alloying metal powder particle size should be -200 + 325 mesh.  Compaction is effected at 10-100 t.s.i. and partial sintering in vacuum, or an inert gas at 900 DEG C.-1500 DEG  C., so that the compact has an elongation of not less than 50% and a tensile strength of not more than 150% of a similarly processed unalloyed titanium compact.  The compact is worked by extrusion, forging, swaging or rolling preferably between 25 DEG  C. and 200 DEG  C. to give a reduction in area of 75%-90%.  The final sintering in vacuum or an inert gas is at 850 DEG  C.-1600 DEG  C. Examples are given of the production of the alloys Ti-Al-V, Ti-Al-V-Cr, and Ti-Cr-Fe-Mo in which the alloying metals may be added separately or as master alloys.  Intermediate annealing may be carried out between the working operations and the final alloy may be heat treated at 900 DEG  C., aged at 600 DEG  C., and furnace cooled.

Title: Improvements in and relating to engine performance indicators
IPC: G01F9/02
Filed: 1946-02-15
Abstract: 608,114. Measuring fuel consumption. LEONARD, C. A. Feb. 15, 1946, No. 4820. [Classes 106 (iii) and 106 (iv)] A meter for indicating the ratio of fuel consumption and contemporaneous speed of an engine includes a first thermo-responsive element adapted to vary its shape in conformity with changes in fuel consumption, and a second thermo-responsive element adapted to vary its shape in conformity with changes in the speed of the engine, each of the thermo-responsive elements having connected thereto a control member for respectively engaging actuators and continuously urging them to turn in opposite directions, and an indicating element operatively connected with each of the actuators. A generator driven by the engine is connected to terminals 16, 17 and supplies current to a heater coil 15 surrounding a bimetallic strip 13, which current varies according to engine speed. A second heater coil 18 round a bimetallic strip 14 is supplied with current from a fuel flow-meter of known type. Rollers 13a, 14a, co-operating with cam slots 4a, 5a in spring- urged discs 4, 5, are displaced when the bimetallic strips bend under the influence of heat, and so allow displacement of the discs 4, 5 by spring action. A pointer 8 with a pivot 8a on the disc 4 and a slot co-operating with a roller 9 on the disc 5, indicates the rate of fuel consumption on a scale 10. In a modification (Fig. 3, not shown), the heater coil 15 is supplied with current from the secondary winding of an induction coil, the make-and-break in the primary circuit being provided by a commutator on the speedometer drive. The indication may be provided by a buzzer or a lamp giving maximum output at maximum M.P.G. In these cases the pointer 8 is replaced by a potentiometer. The device may be used for various types of auto vehicles and stationary engines and may indicate foot-pounds or kilowatts per gallon &c. Automatic adjustment of the carburetter of a petrol engine could also be arranged, in accordance with the movements of the pointer 8.

Title: Improvements in or relating to the manufacture of cutters for boring tools
IPC: B24B3/34
Filed: 1940-03-16
Abstract: 538,998. Making boring tools. SHRIVES, R. W. March 16, 1940, No. 4956. [Class 60] In a method of and machine for making boring tool cutters particularly those of the kind carrying a cutting element as shown in Fig. 5 for use in boring shells or gun barrels the edge of the rotating blank is presented to a grinding- wheel 15 under the control of a rotating templet 16 engaging an abutment surface 11. The tool element a is oppositely bevelled on the edges b, c, the bevels merging at the apex d. A hole e serves for securing the tool to its holder. The machine base 1 carries spaced bearings 2, 2, for a main driving-shaft 3 driven from a motor A through worm gearing 4. An arm 5 loosely mounted on the shaft 3 carries a parallel shaft 7 driven from the main shaft through gears 9. At one end the shaft 7 carries a templet 10 engaging a rotatable abutment plate 11 and held thereagainst by a spring 13. The other end of shaft 7 carries a holding block 14 provided with an inclined face 16 against which the blank is clamped by means of a screw stud 18. The straight edge, Fig. 5, of the blank may be located on a shoulder 17 and an additional clamping bolt 31 may pass through a hole f in the blank. The edge of the blank engages a plane grinding- wheel 15 driven by a motor B and mounted on compound slides 19, 20, the grinding-wheel being reciprocated parallel to the plane of the surface to distribute the wear by gearing driven from the shaft 3 and including bevel gearing 30, shaft 27, crank 27<SP>1</SP> and jointed connecting rod 23. Owing to the inclination of the supporting surface 16, the work has a wobbling motion which results in the grinding of opposite bevels on opposite sides of the blank. The disc 11 may in some cases be positively driven. A pump 35 which circulates lubricating and cooling fluid may be driven from the shaft 33. The boring tool plates may be circular in form in which case the shoulder 17 is omitted from the blank holder. The wheel 9 may be disengaged from the shaft 7 and the latter shaft rotated by a hand wheel 37 to give a more protracted grinding to flat parts of the work. In some cases a hand-made tool may be used in the machine for grinding a templet for use in making other tools.

Title: Device for automatically winding up clocks and setting them right
IPC: G04R20/00
Filed: 1926-02-20
Abstract: 247,996. Lipmann, C., Strahm, F., and Strahm, A. Feb. 21, 1925, [Convention date]. Controlling clocks.-Contacts closed at a predetermined time once per day by the clock mechanism co-operate with a wireless receiving apparatus to wind up and synchronize the clock or clocks automatically at a given radio signal, the operating circuits including a time-limit switch comprising a bimetallic contact device which is heated to close its contact during the silence immediately preceding the time signal and which begins to cool to break the circuit when the time signal is received. Means are also provided whereby the clock is automatically wound up once every four hours. A receiving station 28, Fig. 1, coacts with a telephonic receiver 1, valves 27, and a bimetallic contact device in which the two metal strips 13, 14 are joined at 15 to an insulating member and bend downwards to make contact at 17 when the passage of a current heats the wire 12. At the centre of the receiver 1 is a platinum contact against which, normally, rests a weight 2 held at 3 by a yielding strip 4. Normally the resistance is zero, but when the signal causes chattering of the receiver diaphragm, the device 2, 3, 4 develops a high resistance and is shunted by the relay 9. Once a day, and shortly before the time signal, contacts 6, 7 are closed by the clock, in this case a master clock. This closes a circuit through battery 5 and relay 25, which pulls down armatures 26, 10. Of these, 26 breaks the direct connection aerial 29 to earth 30 and connects the aerial to the station 28 and armature 10 closes the filament circuit of the valves 27, a circuit through device 2, 3, 4. and a circuit through wire 12 and upper contact 11. Contacts 14, 17 close, and when the signal is received chattering occurs at 1, 2 and relay 9 is energized and lowers the armature 11, completing a circuit through a relay 18. This breaks the circuit at 11 through the wire 12, and after a time the bimetallic device cools sufficiently to break contacts 14, 17, thereby disconnecting the relay 18. During the energization of relay 18, however, winding and synchronizing are effected thereby. A modification is described in which the circuits of the wireless apparatus are modified so that the bimetallic contact device is heated during the reception of signals.

Title: Improvements in coin controlled automatic recording playing machines
Inventor: FOEKL WILHELM
IPC: G07F17/30
Filed: 1963-02-07
Abstract: 1,022,263. Coin-freed record playing apparatus. WURLITZER CO. Feb. 7, 1963, No. 5063/63. Headings G4V and G5R. A record-playing machine has means whereby one or more individual records may be selected for playing on deposit of a coin or coins and operation of record selecting buttons 34, 36, and also has means whereby a predetermined set of records may be selected by the mere deposit of a coin.  The records are stacked in a rotating toroidal array 14 and are extracted according to the position of set ones of a circular array of stops 44 engaged by an arm 46<SP>1</SP> rotatable with the stack.  The stops are set by solenoids the actuation of which is under command of the push-buttons 34, 36 and the coin mechanism. A predetermined array of stops is set by a multi-fingered plunger 68 actuated solely under command of the coin mechanism. Coin mechanism.-Fig. 3 shows a coin shoot 16 for selection of individual records, coins passing through a testing mechanism 20 and operating contacts 24, 26, and 28, according to value. The total value of coins deposited is registered in a credit mechanism 30 which is debited according to the selections made by a circuit 32. Demand for the predetermined selection of records is by means of a single coin of value to operate contacts 28. On deposit of such a coin in shoot 46 contacts 50 are made to energize relay 52 which locks up over contacts 52-1 and prepares a circuit for relay 58 over contacts 52-3. If the coin is accepted contacts 28 operate to energize relay 58 which disconnects the credit mechanism and operates solenoid 62 to move the multi-fingered plunger 68 and set the fingers 44 corresponding to the predetermined selection. Relay 52 stays energized until a coin is passed through shoot 16 to break contacts 56. A simplified circuit, Fig. 4, not shown, has a slow-to-release relay 76 which responds to a coin in shoot 46a and stays up long enough to provide an energizing path to solenoid 62a if the coin is accepted and operates contacts 28a.
