Abstract: 1,045,023. Brush-making machines. J. EVANS & SON (PORTSMOUTH) Ltd. Jan. 19, 1965 [Feb. 7, 1964], No. 5322/64. Heading A4K. [Also in Division B3] A brush stock a is held, during drilling or filling, by a fixed jaw and a pair of spring urged jaws 6 and, on completing the operation, is replaced by a blank stock. On reciprocating a fluid-actuated piston 11 to bring the blank stock forwardly on bolster 16, it is forced against the completed stock so as to thrust the latter out from between the jaws. The blank stock is correctly positioned between the jaws when piston 11 abuts plate 19 and the bolster 16 serves as a support for the stock during the drilling or filling operation. The piston 11 is operated in timed sequence with the brushmaking machine and the stocks are gravity fed between guides 21. Arrangements for adjusting the guides and jaws for stocks of different sizes are described. Bolster 16 may be provided with a lateral extension to support the handle of a brush, such as a tooth brush, while the stock is being carried towards the jaws.

Title: Centrifugal casting machine
IPC: B22D13/10
Filed: 1975-02-11
Abstract: 1466037 End-face seals PONT-A-MOUSSON SA 11 Feb 1975 [20 Feb 1974] 5680/75 Heading F2B [Also in Division B3] In a centrifugal casting machine the sealing between a rotary mould in a stationary casing 1 consists of a rubbing member, mounted on the casing, applied under adjustable pressure to a flange integral with or connected to the rotary mould. The casing 1 contains a rotatable mould 2 surrounded by a jacket 3 to form a cooling space 4. Cooling water enters and leaves the casing by pipes 6 through annular rings 7 secured to the casing and passes through openings 9 into the space 4. A flange 10 is integral with jacket 3, and between flange 10 and ring 7 are sealing structures J1-J4. The rigid walls of rings 7 have annular grooves 11, containing elastically-yieldable chambers 12, supplied with fluid under pressure via connectors 13 from pipes 14. The chambers 12 bear on the inner ends of grooves 11 and against an end face of sealing members 17, which in turn bear against the rotatable flange 10. The sealing members 17 may be copper-containing alloys, friction irons or resin coated fabrics, and are prevented from rotating in grooves 11 by radial pins 18. Since the yieldable chambers 12 abut sealing members 17 and the inner faces of grooves 11, any wear of the seal 17 may be taken up by increasing the fluid pressure through pipes 14 and consequently expanding the yieldable chambers 12. The sealing mechanism may be used in both "dry" and "wet" casing types of centrifugal casting machines.

Title: Improvements in or relating to antennas
IPC: B64G1/22
Filed: 1962-02-15
Abstract: 990,246. Aerials. WESTERN ELECTRIC CO. Inc. Feb. 15, 1962 [March 7, 1961], No. 5900/62. Heading H4A. An aerial having a radiation pattern (Fig. 3, not shown) symmetrical about one plane consists of an electromagnetic wave feed 17 and a plurality of conductively connected waveguides 21 radially disposed in the said plane around the feed 17 and means 28 and 29 in each of the guides for producing a 90 degree phase shift between orthogonally polarized waves applied to the guide. In the arrangement shown, the aerial forms part of a communications satellite 10 which receives and transmits circularly polarized waves. The feed of the aerial is formed by opposing conical surfaces 15, 16 forming a circumferential slot 17 between their edges, which is fed by a coaxial connection 18 from the input and output of a repeater 19 through a channel branching filter 20. The feed 17 has a large number of conductively bound square waveguides 21 round its periphery each of which has a pair of conducting vanes 28 and 29 located diagonally in opposite corners of and extending a portion of the way across the waveguide as shown. In operation, the circular wavefront leaving the feed 17 is intercepted by all of the guides so that a portion of the wave excites each guide in a mode having an electric field extending between parallel plates 26 and 27 which define the top and bottom edges of the waveguides. The field is then resolved into one component lying in the plane of the vanes 28 and 29 and the other normal thereto. Upon leaving the guides 21 one component is delayed 90 degrees with respect to the other and the energy within each guide has circular polarization and the energy in the guides combine to form a total toroidal radiation pattern of circular polarization. In place of the vanes 28 and 29 other forms of phase shifting elements may be used such as dielectric vanes or reactive probes. In another embodiment the conical surfaces 15, 16 are replaced by spring tensioned wires (Fig. 4, not shown), and in another the surfaces are insulated by an egg-crate structure (Fig. 5, not shown), formed by a plurality of radial strips intersecting a number of circular strips. In a further embodiment (Fig. 6, not shown), the surfaces 15 and 16 are replaced by a feed formed by a waveguide manifold arrangement consisting of a number of Y-type junctions making successive power divisions in steps of two from the coaxial connection 18. Specification 990,245 is referred to.

Title: Improvements in navigating apparatus for aircraft
IPC: G01C19/00
Filed: 1940-04-06
Abstract: 573,922. Gyroscopic apparatus. SMITH & SONS (MOTOR ACCESSORIES), Ltd., S., and MEREDITH, F. W. April 6, 1940, No. 6263. [Class 97 (iii)] [Also in Groups XXIX and XXXIII] A device for assisting the steering of an aircraft comprises a direction-finder such as a bomb-sight or other sighting device or wireless directionfinder which is rotated in azimuth, whenever a turn is made, by an amount proportional to the speed of the turn and in the same direction, so that the pilot observes the object towards which he is steering or observes the indicated direction before the aircraft is actually headed towards that direction. By superposing a correction proportional to the amount of turn but in the opposite direction the effect of drift may be compensated. In one form a sighting telescope 10, Fig. 1, is trunnioned in a forked pillar 11 on a platform 14 pivoted about a longitudinal pivot 15. A pinion 12 on the pillar meshes with a fixed gear 21. A device 17 responsive to rate of turn controls a servomotor 18 to tilt the platform 14 and consequently 'rotate the telescope 10. Fig. 3 shows a modification in which a free gyroscope 23 rotates about an axis in the longitudinal plane of the machine and is tilted downwardly towards the forward end of the aircraft so that it is responsive both to turning and banking, the latter being proportional to the rate of turn in the absence of sideslip. The gyroscope is mounted in an inner gimbal ring 25 pivoted in an outer ring 26 which in turn is pivoted in a follow-up ring 27 pivoted to the aircraft about the same axis as the ring 26. An arm on the ring 26 is coupled to a pilot valve 29 controlling a motor 30 which by means of a worm gear 31 causes the ring 27 to follow up the ring 26 and simultaneously a motor 33 synchronized with the motor 30 rotates a sighting telescope 37. To prevent change of angle of the gyroscope axis when initiating a dive, the gyroscope may be caged by levers 42, 43 engaging a pin 45 on the ring 25, or a pilot valve 38 may be actuated by movement of the ring 25 to control a motor 39 which turns the ring 26 and causes the gyroscope to precess to its original position relative to the aircraft.

In a carrier telegraph system comprising a bi-stable circuit K, Fig. 2, which controls a switching circuit US in the tuned circuit of a modulator V, the single or double current signals E which are fed to the bi-stable circuit are also passed via a rectifier Gr to a threshold circuit UW, which, when the level of the current from the rectifier falls below a preset value, sets the bi-stable circuit to a chosen state, e.g. Space. The threshold circuit includes a temperature - compensating diode G2 and is fed by floating D.C. derived by a converter GW from the D.C. supply to the modulator V. In the case of double current signals, the rectifier is followed by a capacitor circuit C1, R1 which prevents the threshold circuit from responding to the transitions in signals having slow transitions. To correct marking or spacing bias in single current input signals, a capacitor C2 or inductor follows the rectifier.
