Abstract: 560,271. Wireless signalling. STANDARD TELEPHONES & CABLES, Ltd. Nov. 6, 1942, No. 15701. Convention date, Nov. 8, 1941. [Class 40 (v)] An antenna system for radiating or receiving with equal intensity in all directions in a given plane comprises a pair of elongated sheet conductors 90, 91 spirally disposed around a two-conductor transmission line, each sheet conductor being connected along one longitudinal edge to a different conductor of the line. The sheet conductors may be regarded as surfaces generated by rotating an elemental dipole antenna about the axis of the line, and simultaneously moving it along the axis to provide a plurality of like antenna sections in which the spacing in angular degrees between any two assumed positions of the elemental antenna is equal to the spacing in electrical degrees between the points of connection of the elemental antenna to the line conductors. The transmission line may comprise a vertical mast with inner and outer conductors 101, 102 or two vertical masts each forming one conductor, Fig. 4 (not shown). The structure is earthed at its base through a quarter-wave-length line section 17 to provide a low impedance for lightning and frequencies other than the operating frequency. Reference is made, for explanatory purposes, to an " expanded turnstile " array, Figs. 1 and 2 (not shown), comprising four sections-,- each having six dipoles displaced vertically and angularly by equal amounts. The Specification, as open to inspection under Sect. 91, also describes other " turnstile " arrangements. In one, dipoles arranged; a quarter-wave-length apart and in space quadrature are connected to corresponding points in a transmission line constituted by a hollow flag pole serving as the outer conductor and supporting an inner conductor, Figs. 1 and 2 (cancelled, not shown). In a modification, Fig. 4 (cancelled, not shown), the transmission line comprises two separate masts. In a further modification two transmission lines comprising four vertical masts are used, the phase of the energy in one line being displaced 90 degrees from that in the other, Fig. 5 (cancelled, not shown). This subject-matter does not appear in the Specification as accepted.

Making wafer biscuits.-In a machine for making wafers or the like, independent irons, recessed on each face, are constrained to move in a row so that the opposed recesses of adjacent irons form the mould cavities, and irons removed at one end of the row are transferred to the other end. In Fig. 2, the irons a form a broken annulus and are moved anti-clock'wise, the uppermost iron being laid on the horizontal exposed face of its leader over which a known batter supply device is intermittently positioned. A locking-device prevents retrograde movement of the irons which are provided and guided by rollers c, d engaging with suitable tracks. Each iron has a radially arranged sliding spring-pressed rod o mounted at each of its sides, the rods being bevelled at the upper ends whereby they snap into holes on an oscillating yoke n which removes the uppermost iron and transfers it to the beginning of the row, pressing the whole row forward to preserve its initial position. Cams retract the rods o from the yoke which returns to the position shown in Fig. 2 to engage the next iron. The yoke is operated by duplicate link mechanism comprising swinging levers q, slotted to receive crank pins p and pivot pins r, pivotally connected to the yoke n. A link s connects the batter supply mechanism to a lever q. The irons are hollow to admit the hot gases from burners, or the hollow spaces may contain electric heating-elements taking current by brushes and sliding contacts. The rods o may be replaced by yielding bolts on the yoke adapted to engage openings in the irons.

Filed: 1956-05-22
Abstract: 833,445. Clutches, ratchet and positive; operating clutches. EASY WASHING MACHINE CO. Ltd. May 22, 1956, No. 15851/56. Class 80 (2). [Also in Groups VIII and XIII] In a washing-machine (see Group VIII) a reversible motor (not shown) transmits highspeed rotation through a clutch 37 to a clothes tub shaft 19 when the motor is rotating in one direction, and oscillatory drive through a clutch 39, 40 to an agitator shaft 16 when rotating in the opposite direction. The motor drives one member 36 of the clutch 37 and a gear 33 connected through a pitman 34 to a sector gear 35 meshing with a pinion 38 slidably journalled on the shaft 16. The pinion 38 has teeth 39 adapted to engage a slotted plate 40 secured to the shaft 16 to trasmit oscillatory movement thereto. The pinion 38 can be raised out of engagement with the plate 40 by means of a yoke 41 guided for vertical movement by a pin 42 sliding in a bore 43. The yoke 41 is moved vertically by a pin 44 moving in a diagonal slot 45 in the yoke, the pin 44 being carried by a pivotal arm 46 coupled to the gear 33 through a spring-operated brake 47. On clockwise movement of the gear 33 (Fig. 6) the arm 46 operates to elevate the yoke 41 and pinion 38 and release the pinion from driving engagement with the shaft 16, and vice versa. The clutch 37 includes a clutch ring 56 carrying rollers 57 for coaction with inclined surfaces 58 provided on the clutch member 36. For one direction of motor rotation rollers 57 will run up the inclined surfaces 58 to lift clutch ring 56 into engagement with a cap 51 slidably keyed on the tub shaft 19. The cap 51 is thus lifted out of braking engagement with a cup 48 and a positive drive is transmitted from the belt 28 and clutch member 36 through the clutch member 56 to the cap 51 and shaft 19. On reversal of motor rotation clutch member 36 will be rotated in a direction to cause the rollers 57 to roll down the inclined surfaces 58, uncoupling clutch member 56 from cap 51 and allowing a spring 53 to move the cap 51 into braking engagement with the cup 48 which is fixed to the frame 20. The arrangement is such that clutch member 56 will be moved into driving engagement with cap 51 when pinion 38 is released from driving engagement with shaft 16. Specification 676,348 is referred to.

Abstract: 719,307. Printing-surfaces; embossing. BISHOP, H. L. July 13, 1951, No. 16673/51 Class 100 (2). Mechanical treatment of electrotypes.-A method of treating an electrotype comprises placing it between a face mat having depressions therein and a complementary back mat and subjecting the assembly thus formed to pressure so as to deform the electrotype into the depressions, including the steps of placing the assembly between a pair of flat rigid plate members and supplying the pressure by passing the assembly and plates between a pair ot pressure members the distance between which is equal to the total thickness of the electrotype, mats and plate members. The apparatus comprises a base 10 which supports a motor 14 driving through pulley 16, belt 18, pulley 20, and reduction gearing 22, a gear 32. The gear 32 drives, through a gear 34, a gear 36 mounted on the shaft of a roller 30 and the gear 36 in turn drives a gear 40 mounted on the shaft of a roller 42 which is slightly crowned. The rollers are located beneath a cover 60. An electrotype 100 to be treated has laid upon it a face mat 102 and a back mat 104 and the electrotype and mats are then placed between steel plates 90, 92. This assembly is then placed upon a table 70 of the apparatus having rollers 80 thereon, and fed between the rollers 38, 42. The electrotype is thus deformed into the depressions on the face mat and emerges on to a table 72 of the apparatus. Guides 74 are provided on the table 70, 72. The steel plates are then removed together with the mat 104, and the electrotype together with the mat 102 is shaved to level out its rear surface.
