Title: Improvements in and relating to indicators or signalling devices for vehicles
IPC: G08B5/36
Filed: 1937-12-06
Abstract: 500,993. Detecting approach of overtaking vehicles. BIBBY, A. H. Dec. 6, 1937, No. 33696. [Class 118 (ii)] A signalling device for signalling the driver's intentions or instructions to following traffic is combined in one compartmented casing 5 with a device for transmitting the sound of a horn to the driver. Lamps L are selectively lit by operation of switch S, a microphone M transmitting sound through an amplifier SA to a loudspeaker LS near the driver. The system is under the control of a master switch E, such as the ignition switch, and the signalling switch may be of the type that releases after an interval.

Ink.-In the manufacture of safety paper for cheques, notes, bonds, wills, and other documents, the pulp or paper has incorporated with it an amine of the benzidine group. such as benzidine or its homologues, substitution products, or salts. As examples, benzidine, ortho.tolidine. and ortho-dianisidine are mentioned, and an insoluble salt such as the sulphate is preferred. The substances are discoloured when treated with ink-eradicators. The material may be added to the pulp or to the unfinished web; or the finished paper may be coated; or the substance may be made, up as a stick with a binder such as starch and rubbed on the paper.
Patent GB-945387-A (GB)
Title: Gyro integrator
IPC: G01C19/38
Filed: 1960-10-03
Abstract: 945,387. Gyroscopic apparatus; measuring fluid flow. GENERAL ELECTRIC CO. Oct. 3, 1960 [Oct. 19,1959], No. 33835/60. Headings G1C and G1R. In a gyroscopic integrating device, for example for obtaining an integrated output from a mass flowmeter, in which a gyro rotor 14, rotating about a spin axis AA is universally mounted for movement about major and minor axes, torque being applied about the minor axis to cause precession about the major axis CC and thus drive a counter (not shown) through gearing 52, holding means are provided to prevent precession of the gyroscope about axis CC until the signal torque exceeds a predetermined value. The holding torque may be provided by the rotor levelling arrangement. As shewn, the fluid flowing through a conduit 23 passes through an impeller driven at constant speed by a synchronous motor to impart angular momentum to the fluid which is removed by a turbine whose shaft 25 transmits a torque through rocker arm 26 and cylindrical magnet 27 to a magnet 33 on the lower end of a rod 29. The upper end of rod 29 extends through the hollow lower trunnion 19 along axis CC and bears on an L-shaped lever 36 which is pivoted at 35 on outer gimbal 18 and engages at 41 an arm 39 on the inner gimbal 15 so that on rod 29 sliding upwardly, torque is produced about the minor axis and thus precession about axis CC. To level the gyro, the rotor 14 has a shaft extension carrying a disc 48 with projecting magnets 49. These co-operate with aluminium rings 57, 58, on the gyro casing and by means of eddy currents cause the rotor axis to lie in a plane at right angles to the axis CC since the axis of rings 57, 58 coincides with axis CC. The ring 57 is made wider than ring 58 so that a net drag torque about the axis CC is developed to counteract the load torque imposed by the counter on the gyroscope, or the centre of the conductor ring may be slightly displaced from the centre of suspension of the gyroscope for the same purpose. If there is no flow in conduit 23, nevertheless viscous coupling between the impeller and turbine may result in a small torque being transmitted through rod 29 to the gyroscope. To overcome this, one or more screws 61 are adjustably mounted between rings 57, 58, and by distorting the pattern of eddy currents cause a torque to be developed which opposes the spurious torque so that the gyroscope will not precess about axis CC until the signal torque exceeds this holding torque. In a modification the screw 61 is omitted, a hole in the eddy current conductor member being sufficient to provide the assymmetry required.

Title: Improvements in and relating to locks and keys
IPC: E05B35/00
Filed: 1934-11-27
Abstract: 447,913. Locks. WOLLASTON, H. J. BUCHANAN-, The Pantiles, Pakefield, Lowestoft. Nov. 27, 1934, No. 34032. [Class 44] A sheet material " key is used to position a series of pin or rotary tumblers controlling the movement of a lock bolt. Pin tumblers D are mounted in fixed guides C<1>, C2, El, E<2>, and each has a flange F which is pressed on to a slotted lifting bar H by a spring. In operation the bar H is raised by means of a handle J, the " key is slipped into the slot between the parts E<1>, E<2> and the bar H is released. The " key is perforated to suit the differing ends of some of the tumblers and is not perforated at all for others. When the tumblers have been set by the " key ", the bolt can be moved by the handle J of the bar H. The " key " is preferably flexible and a curved guard W, Fig. 5, may be fitted over the key slot so that the " key must be flexed for entry. The tumblers may be of any suitable kind, e.g., they may be revoluble discs D<3>, Fig. 10A, with sector-shaped gaps corresponding to the top edge of the bolt A and arranged to enter slits in the top edge. The discs are turned by the hand-operated slide H, the key is placed at S and variously shaped pegs R<1>, R<4> on the discs contact with the underside of the key when the discs are released. Instead of engaging the bolt directly, the tumblers may engage subsidiary bolts which engage the main bolt and more than one such subsidiary bolt may be used. In another modification the part A may be fixed and the bolt formed as an extension of the members C<1>, C<2>, the " key " and tumblers moving with the bolt. To enable the bolt to act as a latch, leaf springs on the member H may frictionally engage the tumblers so as to hold them in their unlocked position after removal of the " key." Additional stops are provided on the tumblers in this case to ensure the restoration of the tumblers to their position in positive engagement with the bar H when the latter is raised an amount considerably greater than that necessary to insert the " key."
