Title: Improvements in gyro-compasses
IPC: G01C19/38
Filed: 1922-05-10
Abstract: 206,541. Brewerton, A. E. May 10, 1922. Gyroscopic compasses.-The gyrowheel is mounted on a member permitting of three degrees of freedom and conveying the necessary driving power to the wheel, and is supported within or on a pendulous gimbal system. In the form shown the motor 6 drives a pulley 7 connected by a belt 7<a> to the central part 8 of the gyro wheel, this part being of doubleconical form and carrying the rims 8<a>, 8<b>. The wheel contains a ball bearing 9 for a shaft 10 connected to a link 11 pivoted to a bracket 12 on the base plate 13 of the compass. The orienting torque is produced by amass 14 slidable and rotatable on the shaft 15 and engaging a spring 18. The spring is inclined to the plane of rotation of the wheel so that, when distorted by axial movement of the mass 14, it applies a damping torque. To cause the base plate 13 to follow the gyro-wheel in azimuth, it is adapted' to be driven by reversible means comprising a wormgear 23 driven by a friction disc 22 mounted between the two flanges of a pulley 20 driven by the motor 6. The pulley is adapted to be displaced axially by an electromagnet 27 the circuit of which is controlled by a contact 26 co-operating with the face of the wheel. The worm-gear 23 drives a pinion 24 gearing with a crown wheel 25. The card 28 is mounted on the base-plate 13. The restoring and damping torques may alternatively be derived from the movement of liquid in a level pivoted to the gyro-casing. In a modified construction the wheel is driven by a flexible coupling, the distortion of which is utilized to produce the restoring and damping torques.

Abstract: 449,356. Endless - chain conveyers. GRETLER, O., 27, Bucheggstrasse, Zurich, Switzerland. May 4, 1935, No. 13315. Convention date, May 4, 1934. [Class 78 (i)] Textile material 5 carried by cross-bars 4 is immersed in liquid in such a manner that the contact areas between the bars 4 and the material are constantly changed. The bars 4 connect links 3 hanging from the pivots of two parallel endless moving chains 2, and ride over two lateral cams 6 having top edges in the form of saw teeth. The bars 4 after passing the top edges of the teeth fall more rapidly than the textile material sinks in the liquid, and being also drawn forward during this fall take under a different portion of the material before starting the climb up the incline of the next tooth.
Patent GB-133610-A (GB)
IPC: B61G1/00
Abstract: 133,610. King, J. March 26, 1919. Couplings, non-automatic.-In order to prevent rising of the pin b of a shackle coupling for colliery trams, the pin is provided with a groove which is longitudinal at its lower part c and spiral at its upper part d, the groove being engaged by a projection f which is attached to the upper limb a' of the shackle after the pin has been inserted through both limbs of the shackle. The pin can be raised when a coupling is to be effected by giving it an initial twist and then a vertical lift. Entire withdrawal of the pin is prevented by the engagement of the projection f with a stop e in the groove c or with the closed bottom of the groove c.

Abstract: 405,499. Discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Kenty, C. E. ; 650, Palisade Avenue, Jersey City, New Jersey, U.S.A.) May 9, 1933, No. 13483. Convention date, May 9, 1932. Addition to 395,851. [Class 39 (i).] A tube having a filling consisting of a main gas and a trace of another gas of which the ionizing potential is substantially the same, or somewhat less than a metastable potential of the main gas is started by discharges adjacent each main electrode and between each of these electrodes and an adjacent auxiliary electrode within the tube, which discharges are created by potentials equal to or less than the main supply voltage. In one form Fig. 1, a lamp having a filling of neon plus 0.2 per cent oxygen at a pressure of 1 to 3 m.m. has an indirectly-heated electrode 2 surrounded by a shield 6 at each end, and two auxiliary anodes 9, 10 are excited from tappings on an autotransformer 12 connected across the alternating-current mains to which the electrodes 2 are connected through a ballast resistance 11. The lamp may be U-shaped. In a modification an M -shaped tube has three main electrodes with a pair of auxiliary anodes adjacent each. One electrode is arranged at the mid-point of the tube and is connected to the mid-point of the autotransformer. A continuous-current lamp has a heated cathode and auxiliary electrodes near both anode and cathodes each connected to the other main electrode through a resistance. In another modification, a ring-shaped auxiliary anode is mounted near each main electrode and is fed with continuous-current from a full-wave rectifier supplied by the transformer.

Patent GB-559633-A (GB)
Title: Improvements in and relating to starting switches suitable for electric discharge lamps
IPC: H05B41/06
Filed: 1942-09-25
Abstract: 559,633. Thermal switches. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 25, 1942, No. 13524. Convention date, Sept. 27, 1941. [Class 38 (v)] For starting discharge lamps, means are provided to prevent a thermal switch from repeatedly opening and closing if the lamp is defective, by providing a highly heat sensitive member to break the circuit, co-acting with a less sensitive member acted on by an accumulation of heat in the casing. In the example a bimetal strip 12 bears a contact 14 and a spring strip 16 biased away bears another 18. The contacts are normally strained together by a resistance wire 20 in series with the arms 12, 16 and the lamp electrodes. On closing the main switch the quick heating and lengthening of the wire 20 allows contact 18 to move away from contact 14, for starting the lamp. After repeated unavailing openings, the accumulated heat in the casing 10 causes the strip 12 to withdraw contact 14 from re-engagement until after a period of cooling. In a modification, strip 16 is replaced by a second bimetal strip with high heat-sensitivity and a resistance heater associated with it, the action of the combined strips being the same.

Title: A conduit coupling connecting a spigot end of one conduit to a bell end of another conduit
IPC: F16L37/24
Filed: 1970-03-20
Abstract: 1,249,846. Pipe couplings. NEDERLANDSCHE IJZERGIETERIJ "VULCANUS " N.V. 20 March, 1970 [21 March, 1969], No. 13526/70. Heading F2G. Upon coupling, a spigot 1 provided with holes through which circumferentially spaced fins 3 are resiliently urged is inserted into a socket 2 causing the pins to engage a conical surface 6 and be forced to retreat radially into the spigot until they pass a ridge 17 when they return to their natural positions as shown thus locking behind a surface 14 of the ridge in a position to withstand axial tension. Cams (15), Fig. 2 (not shown), are provided in the socket 2 immediately behind the surface 14 and arranged such that subsequent relative rotation of the socket and spigot 1 in one direction will cause each pin 3 to engage the sloping surface (11) of a cam and upon further rotation the pin will ride up this sloping surface and be forced into the socket 1 until the top of the pin encounters the cam surface (16), with the same radius as the inner surface 17 of the ridge, allowing the spigot to be removed. A sealing ring 7 is held in position, and under pressure if desired, in the locked coupling by a gland 8 and bolts 10 as shown. Initially the pins 3 may be threaded slidably on an open annular spring 4 the ends of which are then bent to form handles (12), (13) whence the spring is contracted and the assembly of spring and pins inserted into the spigot, the pins being urged resiliently out through the holes as required on release of the spring. The coupling is suitable for cast iron pipes since little or no machining is required, and the sealing method allows the coupling to be used underground in particular for natural gas. The coupling forms a universal joint where the pipes may be tilted relatively to each other, and also a joint where the pipes may be rotated relatively to each other before the pins 3 ride-up the cams (15). Either pipe may be part of a valve device.
