Abstract: 787,118. Television. ANTRANIKIAN, H. V. Dec. 1, 1954 [Dec. 3, 1953], No. 34766/54. Class 40 (3). [Also in Group XL (c)] A plurality of frequency bands Sg, Sr, Sb are each reduced in bandwidth by transposing parts of them such as Sgl, Sg2, Sg3, Sr1, Sr2, Sr3, &c. by frequency changing into adjacent mutually exclusive bands S1 S2, S3 of narrow bandwidth and preferably higher frequency. The parts Sg1, Sg2, Sg3, &c. may be separated out by filters and frequency transposed by " dissecting," " chopping " or heterodyning frequencies fg1, fg2, fg3 preferably differing in frequency from each other by an odd multiple of a corresponding fraction, e.g. one third, of the linescanning frequency, or the dissection voltage may be reversed in polarity after the end of each full image. The lower frequency portion S1 may coincide wholly or in part with the higher frequency part Sg3 of the band Sg. The overlapping bandwidths, e.g. Sg, Sr, Sb may correspond to three monochrome pictures or to the green, red and blue frequencies of a television video signal. The parts of each band carrying the D.C. portion must be " chopped," i.e. interrupted, at the transposing frequency; the other portions may be transposed by frequency changers. The outputs of the choppers and frequency changers may be applied to radio frequency, preferably single sideband, modulators, or the transposing frequencies themselves may be radio frequencies. Bandwidth with this system is saved in that the transmission of a vestigial sideband ; i.e. double sideband transmission for low frequencies, is not necessary. Specification 764,479 is referred to.

Air accumulating either within the tubular filter element 44 or in the interior of the filter casing 18 around the filter element can escape continuously during the filter operation through two openings, one of which is in the filter closure 21 adjacent its top and the other is in the top of the rear end of the casing. The openings are connected by flexible discharge pipes 66A and 68 to a storage tank 11 for unfiltered liquid. A small proportion of liquid may also flow through the openings but the cross section of the openings is such as to prevent the flow from effecting generally maintained conditions in the element during operation.

Abstract: 1,245,422. Lawn sprinkler. INTERNATIONAL PATENT RESEARCH CORP. 22 July, 1968 [8 Sept., 1967], No. 34930/68. Heading AID. [Also in Division B2] A lawn sprinkler capable of having its area spray pattern varied comprises a housing 20 provided with a fluid inlet 22, an impeller 24, a distribution head 26, and a pattern selector cam 28 connectedly driven by the impeller. Fluid follows two paths; one is via an impeller directed conduit 34 to the impeller and thence to the head 26 and the nozzles 72' and 74'; the other is to cam directed conduits 32 and 68 and thence via one of the conduits, dependent on the setting of a selector switch 36, 38, to a set of passages 30 in the cam 28 which regulate the flow rate of fluid passing the cams and reaching the outlet nozzles. This also effects the amount of fluid ejected onto the impeller and the combined fluid that ejects from the nozzles, and thus controls the shape of the spray patterns. Gear sets 44, 46, 48, 50, 52 and 54 transmit drive from the impeller to the cam and distribution head which are rotated together. A deflector 42, which is driven by gear set 52, is designed to selectively deflect fluid and effect a uniform radial distribution of water in the selected pattern. The specification contains a reference to Specification 1,245,423.

Title: Improved mechanical combined door knobs and bell
IPC: G10K1/07
Filed: 1922-12-27
Abstract: 210,252. Oates, S. I. M. L. Dec. 27, 1922. Letterboxes. - Relates to systems in which a mechanical bell in a door handle is operated by turning the handle or by means of a push button and consists in causing the bell to be operated also when the flap of the letterbox is raised. An electric bell may be provided in place of or in addition to the mechanical bell and in the latter case may be caused to ring in advance of the mechanical bell. As shown, Fig. 1, the button g of a spring-driven bell e forming one of the knobs is depressed by a bar d. The bar d is depressed by the push button a through spindle c or, when the knob is turned, by the rod h, the end of which is moved by engagement with fixed cams j on the rose k. Movement of the letterbox flap m rotates the rod p, the end r of which is cranked and causes the rod h to be depressed. Instead of spindle c an additional rod sliding in a hole or groove therein may be used for operation by the push button. The bar d and rod h may be in one piece. A catch may be provided to lock the spindle c against rotation. In a modification, Fig. 3, the push rod h engages the cams j through a screw t which may be withdrawn clear of the cams to prevent operation of the bell when the knobs are turned. In an adternative arrangement the cams are connected to the rose by a rib sliding in a groove and may be moved out of the path of the rod h. In a modification, Figs. 6 and 7, in which an electric bell is provided, an insulating washer x is mounted in the rose k and carries a flat contact piece wand a curved contact piece 7. The spindle c carries a contact pin y. When the push is depressed, the pin y comes against contact w and closes the bell circuit. When the knob is rotated, inclined surfaces on the knob make contact with the contact 7. A switch 10 is provided to prevent operation of the bell when the knob is turned. The bell circuit is also closed when the flap m is raised and makes contact with the spring 11. One of the wires 2, 4, 6, 9 may be in the form of a telescopic brass tube, and the other wires may run within it. The push button may operate a sleeve sliding over spindle c instead of the spindle itself. The electric bell may be arranged in the door knob. The thumbscrew t, Fig. 3, may be replaced by a fixed pin or cam, the rod h being rotatable to cause these to move clear of the cams on the rose when the door knob is turned.

Title: Electric discharge tube
IPC: H01J21/08
Filed: 1933-12-21
Abstract: 432,350. Converting. STETTLER, O., 102, Giesshubelstrasse, Z³rich, Switzerland. Dec. 21, 1933, No. 36020. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 22, 1934.] [Class 38 (ii)] [See also Groups XL and XXXVIII] An electric discharge tube for conversion purposes has an anode, a cathode and a screen located so closely adjacent the current-emitting surface of the cathode or the current-receiving surface of the anode, that any part of the surface covered by the screen does not contribute to the discharge which takes place between the uncovered portion of surface and the other electrode, the arrangement being such that either the screen is movable relatively to the active anode or cathode surface, or the anode or cathode is movable relatively to a stationary screen, so as to influence the magnitude of the discharge currents. In an example, Fig. 5 (not shown), a tube having two enclosed anodes has a screening member on a spring strip which is arranged to uncover the anodes alternately when vibrated by an electromagnet within the tube supplied with an alternating current. If the screen is vibrated by a source of constant frequency it acts as a commutator, and the device can be used to convert direct into alternating current ; if the current produced is fed back to the control magnet, it becomes an inverter producing alternating current at the natural frequency of the spring. The same device may be used as a rectifier. In a modification, Fig. 6, for converting direct into threephase alternating current the movable member 17 is a cylinder having two compartments and supported on a pivot 21. A magnetic armature 18 secured to the member 17 is rotated by a rotating magnetic field produced by the winding 19. The upper compartment 17<a> has a quarter of its circumference cut away and contains an anode 22 of graphite. The lower compartment 17b has a slot similar but diametrically opposite to that in 17<a> and contains an indirectly heated cathode 23. Arranged symmetrically around the movable screen are three members each comprising a cathode 26 directly above an anode 27 and electrically connected thereto, each pair being connected to an apex of a delta-connected three-phase load. The direct current source is connected between the anode 22 and the cathode 23, and when the screen rotates the direct current source is switched across each arm of the load in such a manner as to produce a three phase current. By suitably shaping the slots in the screen any desired wave form may be obtained. The windings 19 may be fed from a separate source of controlled frequency which may be a tube according to the invention, or from the mains being supplied, if these are already under voltage.
