Abstract: 1390504 Timers; metronomes E S PERRY Ltd 20 March 1972 [13 April 1971] 9238/71 Heading G3T To produce audible oscillation of a body in a plane, the body is biased toward a stable equilibrium position defined by two edges and means are provided to define a position of predetermined displacement from equilibrium so that when the body is released from the displaced position, it oscillates through the equilibrium position producing a series of audible sounds for a predetermined time. Fig. 1, shows a body having a cylindrical surface formed by a pair of rails 1 cut away to form edges 5. The body is in equilibrium when standing on the edges. If it is tilted on to a side surface 2 and then released, it oscillates for a time about the upright position under the influence of weight 4, producing a series of clicks as the edges 5 strike the supporting surface. In an alternative arrangement, the body is in the form of a pendulum comprising a weight (14), Figs. 3, 4 (not shown) which is adjustable on a calibrated arm (12). A releasable catch (13) defines the displaced position of the pendulum. The arm (12) is attached at its upper end to a platform (15) having a pair of knife edges which, during oscillation, strike a flat surface of a pendulum support (19) to produce the clicks. The knife edges may alternatively be on the support surface.

Title: Improvements in or relating to devices for signalling, acoustically and/or optically, given speeds of vehicles
IPC: G01P1/10
Filed: 1938-01-04
Abstract: 508,939. Speed signalling devices. PALMER, F. J., and WRAY, R. W. Jan. 4, .1938, No. 9460/37. [Class 106 (iii)] A device for signalling acoustically and/or optically given speeds of vehicles, comprises a totally enclosed non-conducting cylindrical casing in which an externally adjustable piston with contact ring is slidable upon the spindle of a centrifugal governor for making contact with contact members arranged in staggered positions on the casing for operating acoustical and/or optical signalling devices. In the construction shown in Fig. 1, the vehicle driven spindle 1, which can be connected to a flexible speedometer cable at 2, has a slot 3 for driving a centrifugal governor 4 by means of the pin 4a, the governor controlling the position of a metallic piston 7, which is in two portions connected by a ball bearing, the lower portion being connected to the governor 4 by the pin 4a. The piston 7 is under the action of the spring 8 and is freely slidable on the spindle 1, the upper portion being prevented from rotating thereon by means of guide pins 9. The piston 7 has a groove housing the two halves of a piston ring 10 pressed outwardly by springs to make contact with staggered contacts C, C<2>, C3, C<4> moulded in the non-conducting cylinder 6 and connected with an electric power source and with acoustical and/or optical signalling devices. The face of the spring 8 and thus the position of the piston 7 can be externally adjusted by means of the screw bush 13 and lock nut 14. In the construction shown in Fig. 3 there is a gap between the ring halves 10 and the inner surface of the cylinder 6 and the contacts C-C<4> in the cylinder wall project inwardly to prevent wear. The cylinder 7 is not connected to the governor 4 but is kept in contact therewith by a spring 8a. A sleeve 15, having bayonet slots 16, adapted to be secured to the gearbox of the vehicle serves for easily detaching the device and rapid adjustment thereof. Wear due to friction of the contact ring 10 on the inner surface of the cylinder 6 can be prevented by providing metallic bars in the wall of the cylinder between the contacts. In the construction shown in Fig. 11, the contact ring 10 is in one piece and is not spring actuated but the contacts C-C<4> are movable under the action of externally arranged springs 11. In another modification a casing can be provided with an opening for receiving an axially movable panel carrying the contacts C-C<4> to enable adjustment of the relative position of the contacts with the contact ring to be effected. Other modifications are described

Title: Improvements relating to a brake device acting on the front and rear wheels of motor-cycles and like vehicles
IPC: B60T11/04
Filed: 1939-03-28
Abstract: 509,754. Brakes for motor-cycles &c. FAIRBHOTHER, H. (Bayerische Motoren- Werke Akt.-Ges.). March 28, 1939, No. 9708. [Class 136 (i)] In mechanism for actuating both the front and rear wheel brakes of motor-cycles &c. from a single lever, wherein the rear wheel is braked more strongly than the front wheel by an adjustable amount, the transmission of the braking force from the actuating-lever to the force-transmitting members of the brakes is effected through the medium of a normallystressed compression spring, the arrangement being such that the front wheel cannot be braked more strongly than the rear wheel, even when the rear-wheel brake has become worn. A pedal lever 1 turning about a pivot 5 is pivotally connected to a casing 2 containing a stressed compression spring 9, which first transmits the braking force to a collar 10 on a .pull-rod &c. 8 actuating the rear-wheel brake lever 11, the casing 2 then moving forwards, thus flexing outwardly the sheath 3 of a Bowden wire 4, which thus applies a pull on the frontwheel brake lever 7 and an equal additional pull on the rod 8. The initial compression of the spring 9 is adjusted by a wing-screw 12. The front brake may be actuated independently by means of a Bowden wire 12 and a handlever.

Title: Improvement in producing aluminium coated metal articles
IPC: C23C2/12
Filed: 1949-04-12
Abstract: In a method of making an aluminium-coated ferrous article and more particularly compressor blades for jet propulsion engines, ferrous powder is compacted and sintered and the resulting body infiltrated with copper or a copper alloy, coated with aluminium by heating to between 735 DEG  and 850 DEG C and then dipping into a bath of molten aluminium or aluminium alloy and the coated body then heat treated at between 300 DEG  and 600 DEG C in order to precipitate copper in the ferrous skeleton and iron in the copper infiltrant and to alloy the coating with the surface of the body.  Iron powder of particle size below 100 mesh and which may contain known amounts of alloying constituents of alloy steel, is compressed at 20-30 tons per square inch and sintered for about an hour at 1100 DEG -1150 DEG C in a protective atmosphere such as cracked ammonia. The sintered body is then forged at 30-35 tons per suare inch to the exact vane shape required for the leading and trailing edges and infiltrated with copper or a copper alloy such as one containing 2 per cent iron and 8 per cent manganese.  At the temperature of infiltration the metals of the infiltrant and skeleton interdiffuse and the body is subsequently cooled at such a rate as to retain the dissolved copper and iron in excess of the amounts which can be held in solution at normal temperature.  The body is then dipped into heated flux and into molten aluminium or alloy thereof containing, for example, 4 per cent copper and 0.5 per cent manganese, at 735 DEG -850 DEG C, which process heats the matrix to a temperature within its austenitic range so that only slight alloying occurs between the aluminium and the surface of the body. During the subsequent heat treatment at 300 DEG -600 DEG C, preferably at 500 DEG C for about one hour, alloying of the coating occurs owing to the greater solubility of aluminium in iron below its p  transformation point.  The coated body may now be further shaped by pressure if desired, the aluminium acting as a lubricant and finally the outer surface of the coating may be rendered corrosion resisting by electrolytic oxidation or by the deposition of a coating of refractory oxides on the aluminium. Specification 660,027, [Group XXII], is referred to.
