Title: Rotary hydraulic jar mechanism for use in well-drilling operations
IPC: E21B31/113
Filed: 1927-07-27
Abstract: 294,769. Shaffer, W. D. July 27, 1927. Borehole apparatus.-A jar for use in welldrilling operations comprises a hammer member movable relatively to an anvil member and controlled by a pressure fluid so that on exerting a pull on the hammer member, the latter first has a retarded motion and is then suddenly released to strike the anvil.' A casing 10 has a lower cylindrical chamber 11, an upper and larger cylindrical chamber 12 and a bleed port 36, a coupling 15 below the casing 10 being provided with a hollow extension 21 carrying a removable plug 22 with a square bore; a piston member 24 normally slidably engages the lower chamber 11, has a square depending extension 32 loosely engaging the square bore of the plug 22 so as to convey rotation, and also has an upper stem 25 passing through the head 13 of the casing 10 for connection to a string of drill-piping, the lower part 26 of the stem 25 being reduced to a diameter less than that of the bushed bore of the head 13. The parts 25, 32 are hollow for the passage of flushing fluid. Passages 30 in the piston 24 contain ball valves 31 permitting passage of fluid from the chamber 11 to the chamber 12 but preventing return flow. A drill, or a fishing tool 35, Fig. 2, is secured below the casing 10. If the drill sticks, or a part, such as a broken drill engaged by the fishing tool, is to be removed, the string of drill piping is put under tension and thereby stretched; leakage occurs through the bleed port 36 and the piston 24 slowly moves out of the chamber 11 while the reduced part 26 of the stem 25 simultaneously moves through the bore of the head 13; the retarding effect of the fluid is suddenly released, the drill piping contacts, and the piston 24 strikes the head 13. On returning the parts to their original positions, fluid flows from the chamber 11 through the passages in the piston 24 to the chamber 12, and a further blow may then be given. In a modified construction, the bleed port is provided in the piston 24 and connects the chambers 11, 12, whiles In a further modification, the bleed port is omitted, the necessary leakage then being provided around the piston 24.

Title: Improvements in or relating to electrically heated apparatus for the production of semi-conductor material
IPC: C30B25/14
Filed: 1957-06-25
Abstract: <PICT:0861135/III/1> Silicon is formed by introducing a gaseous or vaporous compound thereof, e.g. silicon tetrachloride or silicochloroform, with hydrogen through a nozzle 7 into a chamber 9 containing rods 1a, 1b of silicon thick enough to be self-supporting, each rod being mounted at one end on the container, and the rods are connected so that on passage of current therethrough silicon deposits on the rods.  The rods are purified by zone refining.  The rods 1a, 1b are clamped at their lower ends in graphite clamps 2a secured in metal tubes 3a secured to a water-cooled base member 5 of the quartz chamber 9.  The ends of the rods 1a, 1b may be thickened and secured directly to the metal tubes 3a, one of which is soldered to the metal base 5 the other being insulated therefrom by porcelain tube 4 and being internally watercooled.  The free ends of the parallel rods 1a, 1b are connected electrically by a bridge 6 of graphite, which may have arms extending to the walls of the chamber to form a support. Gas enters the chamber through a pipe 7 with a jet at the end below the level of the clamps 2a to give a turbulent gas flow along the rods 1a, 1b and leaves by an outlet 8.  In a modification, three silicon rods are supported from above by a base 5 and are inclined inwards so that their ends touch, whereby on passage of 3 phase current, these ends fuse together.  As the silicon has much greater resistance when cold, an initial current of high voltage and low current is first applied to the rods and when they are hot, a higher current at lower voltage is applied, and the current is increased as the silicon grows on the rod.  This is effected by connecting the rods first to the tapped primary 11 and then to the secondary 12 of a transformer (see Group XXXV).  Reference has been directed by the Comptroller to Specification 809,250.

Title: Television signal processing apparatus
IPC: H04N5/208
Filed: 1975-05-14
Abstract: 1510504 Colour television receivers RCA CORPORATION 14 May 1975 [5 July 1974 27 Feb 1975] 20326/75 Headings H4F and H3U The receiver includes a tapped delay in the luminance channel, signals from the delay being used to develop a luminance signal which has preshoot and overshoot at transients, and in which the transients are steepened, so providing a more crisp display. The arrangement operates as a filter and can be designed to amplify the high frequency portion of the luminance signal while at the same time attenuating any chrominance or sound components present in the luminance channel. In addition the delay is designed to compensate for the difference in the time delays in the luminance and chrominance channels. Two of the delayed signals, which are separated by a time n/2f (where n is integral and greater than one, and f is the frequency at which attenuation is to occur) are combined to form a first combined signal which is combined with a third signal, derived from one or more delayed signals which lie between the first two delayed signals to form an output signal. The first combined signal is used to control the peaking characteristics of the output signal, the output signal being passed to luminance processing circuitry. In one embodiment, Fig. 2, the delay has three taps 38a-38c at time intervals TD, Tl, T2. The taps are connected to amplifiers 40a-40c, the sum of the outputs of 40a and 40c being subtracted (212) from that of 40b to generate a signal which after amplification or attenuation (214) is added (216) to the output of amplifier 40b, which is the third signal referred to above. Fig. 4A illustrates a transient signal as it would appear (a, b, c) at the taps 38a-38c. Fig. 4B illustrates the output (b) of amplifier 40b, the sum (a+c)/2 of the outputs of 40a and 40c, and the output of summing unit 212. Fig. 4C illustrates the output of summing unit 216. The degree of preshoot and overshoot is selected by adjustment of unit 214. To compensate for phase/- frequency non-linearities in other parts of the receiver the amplification of amplifiers 40a and 40c, and/or the delay periods T1, T2 may be made unequal. In a modification, Fig. 5 (not shown), which allows the attenuation peak and the amplification peak to be closer together, the delay line has four taps, the signals from the inner two taps being summed to form the third signal which is utilized as in Fig. 2. The delay line may be terminated by an open circuit so the video signal is reflected from the end of the line, permitting single taps to be used instead of pairs of taps. In further modifications. Figs. 10 and 13 (not shown) the amplifiers connected to the taps are omitted, and each tap is connected to a common point via a resistor to develop the third signal at that point.
