Title: Method and apparatus for charging surfacing material into surface finishers operating on inclined surfaces
IPC: E02B3/12
Filed: 1963-12-06
Abstract: 996,868. Lining dams. STRABAG BAU-A.G. Dec. 6, 1963 [Sept. 25, 1963], No. 48368/63. Heading E1H. [Also in Division B8] A method of charging surface finishers 4 with surfacing material when the finishers are operating on inclined surfaces e.g. dam embankments, comprises bringing the material to the crest of the dam in lorries having end tippers, swinging the lorries by means of a crane 6 positioned on the crest of the dam, in front of the finisher 4 adjacent bin 5 on the finishers for receiving the material, and during delivery of the material causing the lorry to advance at the same speed as the finisher 4. As shown, provided on the crest of dam D is a winch truck 1, the double rope winch 2 with ropes 3 moving the finisher 4 up and down the dam embankment in order to apply a sealing surface d thereto. Finisher 4 carries bin 5 for the surfacing material and means for spreading and compacting the material in the form of strips disposed side by side along the embankment. After each strip, the finisher 4 is drawn into the winch truck which advances on the crest of the dam to the extent of the width of the surface strip. Mounted on the winch truck is a swinging crane 6 by which the lorries are swung into the working path of the finisher until their tiltable platforms touch the finisher and the material is loaded into bin 5. The finisher may push the lorry before it while the loading progresses. A special container 8 on the lorries permits the material to assume a position such that its C.G. coincides with or is vertically above the C.G. of the empty lorry.

Title: Linear particle accelerator
IPC: H05H9/00
Filed: 1966-10-28
Abstract: 1,142,707. Linear particle accelerators. VARIAN ASSOCIATES. 28 Oct., 1966 [29 Oct., 1965], No. 48525/66. Heading H1D. In a travelling-wave linear accelerator comprising a disc-loaded waveguide, the distance s between input drift tube 31, or the input disc, for the particles and the effective mid-plane of the first cavity D1<SP>1</SP> is set at O#s<L/2 where L is the distance between the midplanes of adjacent cavities. This is to ensure that the injected particles will interact with the maximum strength portion of the acclerating field in the first cavity when there is a large difference between the velocity of the particles and the phase velocity of the travelling wave, e.g. at L-band frequency. In another embodiment the axial length of the first cavity is reduced from the normal length by the distance s. The accelerating waveguide may be designed to have a uniform phase velocity equal to the velocity of light or a phase velocity increasing along the waveguide. An experimental procedure involving the transport of a dielectric bead along the axis of the waveguide is described for determining the phase shift characteristics of the guide.

Title: Improvements relating to colour television systems
IPC: H04N11/18
Filed: 1962-12-24
Abstract: 1,031,246. Colour television. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Dec. 24, 1962 [Dec. 22, 1961], No. 48562/62. Heading H4F. In a colour television system there is transmitted continuously a brightness signal as modulation of a main carrier wave and two or more colour or colour difference signals one after the other line-by-line as amplitude modulation of a sub-carrier wave with suppressed carrier. In the specific embodiment described the signals employed are red and blue colour difference signals. A synchronizing " burst " at subcarrier frequency is transmitted every other line to identify which of the two signals is being transmitted and also to provide a reference frequency whereby the suppressed carrier may be restored at a receiver. The subcarrier is transmitted within the band of the brightness signal with a full lower side-band and vestigial upper side-band, Figs. 8 and 9 (not shown). At a receiver, Fig. 5 (not shown), the carrier is restored to the subcarrier signal from an oscillator synchronized by the subcarrier " bursts " and is then amplitude detected in the customary manner. The derived line sequential red and blue colour difference signals are translated into simultaneous signals with the aid of circuit including a one-line duration delay line and a double-pole, changeover switch. The switch is actuated by linescan pulses and established in the correct phase by the subcarrier synchronizing " bursts." A green colour difference signal is derived by matrixing. The signal together with the red and blue colour difference signals and luminance signal is then applied to a three-gun cathoderay display tube. Colour killing is effected by switching-off the sub-carrier channel in the absence of synchronizing bursts. In a modified receiver, Fig. 6 (not shown), the subcarrier signal after restoration of the carrier is passed directly to the delay line so that the signal delay is effected at carrier frequency. This permits the use of a supersonic or magnetostrictive delay line. The delayed signals are converted to simultaneous form and are then amplitude detected by separate detectors in the red and blue channels. This receiver forms the subject of Specification 1,031,247. The signal employed for restoring the suppressed carrier need not be of precise phase since phase errors introduce saturation errors without altering hue. Reference is made to the use of signal which is adjustable in phase over a range of 90 degrees to permit control of saturation. Automatic control of saturation may be effected in response to the amplitude of the " burst " at the output of a detector.
