Title: Improvements in television synchronizing circuits
IPC: H04N3/20
Filed: 1940-04-18
Abstract: 542,639. Television receiving circuits. PHILCO RADIO & TELEVISION CORPORATION. April 18, 1940, No. 7029. Convention date, May 4, 1939. [Class 40 (iii)] In a television receiving circuit for signals of the kind shown in Fig. 1B, a pulse of amplitude x is extracted from the line synchronizing channel and fed into the picture channel to convert the signal to the form shown on the left in Fig 1C, and a subsequent stage in this channel includes cutting off means for passing only signals above the level shown in dotted lines, that is for passing the picture signals lying above that line. Hence, if the line synchronizing channel fails to operate, the signal in the picture channel will fall below the cut-off level as shown on the right in Fig. 1C and will not reach the cathode-ray tube which is thus protected against operation when the line scanning is not operative. As shown in Fig. 2, the line synchronizing channel comprises valves V 1 , V 2  which are suitably biased to isolate the syncnronizing pulses to control a valve oscillator V 3  which actuate a valve discharge circuit V, with a " peaking " resistor 7 connected to a valve V, from which a combination sawtooth voltage and impulse voltage is supplied to the deflecting coils 8 of the cathode-ray tube 14. The picture channel includes the amplifying tubes V 6 , V 7 , V 8  followed by the diode leveller. The pulses are extracted from the line synchronizing channel and fed into the picture channel by way of the condenser 11 and isolating resistance 12. The points of connection between the two channels may be varied.

Abstract: 696,214. Pallets for handling and stacking loads. FISHER & LUDLOW, Ltd. June 22, 1951. [March 22, 1950] No. 7123/50. Class 78 (iv). The feet of a four-way-entry pallet comprise at least one pair of rigid metal feet 11 (Figs. 1 and 4) of channel section depending from the base 10, the two sides 13 of each foot defining an opening for an arm of a fork truck. In the pallet of Fig. 1 the channel-section feet 11 are formed with corrugations 17 (Fig. 3) and with flanges 14 by which they are welded to the platform 10. The feet at opposite sides of the pallet are aligned so that the tines of a fork truck may each pass through two aligned feet, and the walls of the feet are sufficiently closely spaced to limit lateral movement of the pallet relatively to the arms. In the alternative construction of Fig. 4 two channel-section feet 11 extend across the under side of the load platform 10 and their walls 13 are provided with aligned apertures 18 to provide for four-way entry. The load platform 10 is preferably formed of spaced superposed metal sheets connected together. Walls may be fitted to the load platforms 10 : the upper edges of such walls are preferably reinforced along their upper edges to permit pallets to be stacked one on top of another. Specification 627,200 is referred to.

Abstract: 145,147. Smith, A. March 25, 1919. Heating by electricity.-In apparatus for arc welding and cutting, a non-consuming fluid-cooled metal electrode is used. Two such electrodes may be employed, with or without a fusible metal electrode. In apparatus for welding the joint of a pipe, as shown in Fig. 1, the pipe 2, which is preferably preheated in a furnace 1, is fed by rollers 14 under an are from a fluid-cooled electrode 3, then under an arc from a fusible metal electrode 4b, and afterwards under an arc from another fluid-cooled electrode 7; which causes slag to be brought to the surface to enable it to be removed bv a cutting tool 9. A shaping-belt may be provided between the tool 9 and the rollers, and a mandrel may be mounted in the pipe between the rollers. The electrode 3 may consist of a U-shaped pipe of elliptical section, or a hollow rotary wheel driven by a motor, or, as shown in Fig. 15, as applied to a portable electrode with an insulating holder 27, it may consist of a tube 18 with inlet and outlet fluid pipes 20, 22, one of which may be inside the other. The pipes are connected to a pivoted block 30, Fig. 1. To start the arcs each electrode is withdrawn from the pipe by means of an electromagnet 39. The electrode 7 may be oscillated across the joint by an electric motor 45, Fig. 14, connected by a link 46 with a support 35 sliding in guides 42. The electrode 4b is fed automatically by rollers 48, Fig. 12, driven by a motor 50 through a speed-changing and reversing clutch consisting of a friction roller 56 engaging with disks 57. The speed of feed may be controlled by the current in the arc by means of an electromagnet operating a rod 59 and lever 58 controlling the position of the roller. In a modification, the fusible metal electrode is omitted, and two fluid-cooled electrodes are mounted on either side of the joint.

Title: Double-acting fluid injector
Inventor: JACKSON HAROLD ERNEST
IPC: F16N27/00
Filed: 1956-03-09
Abstract: 845,188. Delivering measured quantities of liquids. TECALEMIT Ltd. Feb. 1, 1957 [March 9, 1956], No. 7506/56. Class 106(5) [Also in Group XXXIV] An injector lubricator comprises a doubleacting piston 3 adapted to be reciprocated in a cylinder 2 by'oil supplied alternately to each side of the piston and then discharged to the place of use, the oil supply being controlled by a slide valve 15 located in a cylinder 14. A piston 30, working in a cylinder 32, is attached to the end of the slide valve 15 and compressed air supplied to the cylinder 32 maintains the valve 15 in its upper position. Oil under pressure supplied to an inlet 20 passes through a vertical transfer passage 17 to an annular space in the cylinder 14, between parts 23, 26 of the valve 15, and thence through a lower cross passage 16A to the underside of the piston 3 in the cylinder 2 forcing the piston 3 upwardly. The oil in the cylinder 2 above the piston 3 is forced through an upper cross passage 16, through an annular space 25 in the cylinder 14, between parts 22, 23 of the valve 15, to an outlet union 43 which is connected to the place of use of the oil. When the supply of compressed air to the cylinder 31 is cut off, the valve 15 is moved downwardly by the pressure of the oil on its upper end. This allows oil to pass through the upper cross passage 16 into the cylinder 2 forcing the piston 3 downwardly and expelling the oil beneath it through the lower cross passage 16A to the outlet union 43. The piston 3 has a rod 3A which extends through one end 9 of the cylinder 2 and is adapted to abut an adjustable stop 40 for varying the stroke of the piston 3 and hence the quantity discharged. Elongated openings 39 are provided in a pillar 38, which has graduations 41, so that the tip 40 of the adjusting screw and the end of the rod 3A may be observed. In a modification the position of the slide valve 15 is cyclically controlled mechanically by an arrangement comprising a pivoted lever 50, Fig. 5, engaging a cam 52. The end of the valve 15 carries a head 49 which is pressed into engagement with the lever 50 by a spring 47. In another modification the lower portion 26A, Fig. 6, of the valve forms the core of a solenoid comprising a coil 54. The movements of the valve 15 are limited by collars 56, 57. Specification 845,187 is referred to.
