Title: Improvements in weft detector mechanism for looms
IPC: D03D51/34
Filed: 1930-06-24
Abstract: 357,583. Centre fork weft stop motions. MITCHELL, J., Victoria Mills, Low Moor, Bradford, Yorkshire. June 24, 1930, No. 19175. [Class 142 (i).] In looms provided with a centre weft fork, the sliding member, which is furnished with the usual cam for rocking the fork, is mounted in such a position that the cam is located outside the cloth selvedge, the arrangement permitting easy adjustment of the parts without displacement of the fabric or the warp. The fork 2 is mounted on a rod 4 pivotally supported in brackets 5, 7 on the lay and provided at its outer end with a member 6 adapted to overhang the cam surface 8a of the sliding cam piece 8. The latter is reciprocated during the movement of the lay by means of a rod 9 having a pin 91 positioned between two springs 11 in a fixed bracket 10, but on the absence of weft the member 6 engages a catch 8c of the cam piece and arrests its movement whereupon a projection 8b engages a bunter 12 and stops the loom.

Title: End-fire aerials
IPC: H01Q13/24
Filed: 1958-06-16
Abstract: 867,356. Aerials. HERSCH, W. June 16, 1958, No. 19231/58. Class 40(7) An end-fire aerial system comprises a radiating element consisting of a metallic rod or tube coated externally with dielectric material and having a wave launching or collecting means associated with one end thereof. As shown in Fig. 1 a metal tube 1 is provided with a dielectric coating 2 and the launching means consists of dipole elements 3 supported in insulating bushings 4 and coupled to feeder 7. A reflecting piston 6 prevents energy from travelling along the inside of the tube 1 and reflector elements 5 prevent back radiation. Instead of a wire feeder 7 an extension of the tube 1 can be used as a circular waveguide feeder. In another embodiment also using a waveguide feeder 12 the aerial consists of a metal rod 9 provided with a dielectric coating. A shaped mode convertor 11 consisting of an extension of the dielectric rod coating converts from the H 01  mode in the circular guide 12 to the HE 11  mode along the aerial. Discontinuites, such as the grooves 15, may be formed in the aerial dielectric to increase the gain. The same effect may be achieved by tapering the dielectric material or reducing its thickness in steps.

Title: Process for the centrifugal separation of minerals

Filed: 1964-05-08
Abstract: 1,000,717. Centrifugal separators. BETEILIGUNGSUND PATENTVERWALTUNGS G.m.b.H. May 8, 1964 [May 11, 1963], No. 19327/64. Heading B2P. Fine-grained minerals are separated from a slurry by means of a collecting basket 2, Fig. 1, which rotates in a stationary vessel 1 containing the slurry and is provided on its inside with grooves in which the heavier fractions of the minerals separated by centrifugal force collect, the slurry being removed from the vessel after separation while the basket is rotating after which the heavier fractions are removed from the basket. The basket is mounted on a shaft 3 driven by a motor 4 and carrying at its lower end a stirrer 5 which produces rotation of the slurry in the vessel 1. Turbulence is produced in the stream of the rotating slurry by means of vertical baffle strips 6 fixedly arranged in the vessel 1. The slurry is fed from a tank 10 through a valve 11. A 3-way cock 12 serves to close the vessel outlet 9 or to connect it via a pipe 13 to a collecting tank for the heavier fractions or via a pipe 14 to a second vessel 1 situated at a lower level thereby to feed the latter by gravity with slurry discharged from the first vessel, the pipe 14 from the second vessel being connected to a third vessel or to a collecting tank. After discharge of the slurry from the vessel and before the heavier fractions are removed from the basket, the vessel is rinsed with clear water introduced through pipes 15, 16 and nozzles 17. The rinsing water may be recirculated into the vessel by connecting the pipe 13 via a pump to a return pipe. The heavier fractions may be removed from the grooves in the basket 2 by means of a scraping tool or, as shown, by means of spray water or compressed air supplied through a pipe 18 and nozzles 19. The basket 2 may rotate at a lower speed during removal of the heavier fractions. The vessel may be rinsed out with clear water after removal of the heavier fractions and the rinsing water directed to the collecting tank for heavier fractions. In Fig. 2, two pressure vessels 20 provided with lids 22 are arranged side by side on the same level. The slurry is forced from one vessel to the other by means of compressed air fed through a valve 23. A mushroom-shaped screening body is provided over the outlet 9 to prevent compressed air being blown straight into the pipe 26. The same slurry may be fed several times to the same vessel. In a modification of Fig. 2, the vessels have no baffle strips. In a further modification, the vessels 1 or 20 may be formed with an approximately horizontal bottom 28, Fig. 4, and with a tangential outlet 29 arranged in the direction of rotation of the rotating basket 2.

Title: Automatic frequency control and station searching arrangement

Abstract: 1,064,448. Automatic tuning arrangements. STANDARD TELEPHONES & CABLES Ltd. May 13, 1964 [May 14, 1963], No. 19891/64. Heading H3Q. In a signal-seeking, self-tuning receiver, tuning is effected by voltage-variable capacitors 8, 9, controlled by the voltage across a capacitor 11, arranged to be charged and discharged so as to sweep the receiver over its tuning range. As shown, the input and local oscillator circuits of a transistorized radio receiver are respectively tuned by variable capacitance diodes 8, 9 controlled by the voltage across capacitor 11. The tuning may be set to the high frequency end of the range by closing switch 10, charging capacitor 11. Switch 12 is then closed, enabling tuning to be swept over the range by the discharge of capacitor 11 via switching transistor 7. When the receiver is tuned to a signal, the voltage from the frequency discriminator 4 acts on a relaxation stage 6 in such a way as to open the switching transistor 7 so that the sweep is arrested, the tuning being maintained by repetitive charging and dsicharging of capacitor 11 so that the tuning oscillates over a small range at the centre of the characteristic of discriminator 4. The tuning may be swept to further channels by closing switch 12. The negative output of discriminator 4 is by-passed by diode 17, a filter 15, 16 preventing false operation due to noise.
