The warping and bending of metal and cemented carbide blanks having at least one shaping surface is overcome by sintering the blank in a refractory mould shaped to the blank and tapered so that the blank on shrinking slides down the mould taper. As shown, the WC-Co blank2 is inserted into the graphite mould 1 which has an inclination angle α equal to that of the blank. The mould when charged with blanks is heated to sintering temperature when the blanks slide down the mould cavity on shrinking to size. Drills, cutters, reamers, taps guide bars and flat tips may be sintered in this manner.

Title: Colour telecine encoding and decoding system
IPC: H04N5/84
Filed: 1978-08-01
Abstract: A colour image is recorded on film at the television field rate with adjacent regions of the film representing luminance and encoded chrominance information. The chrominance information is encoded by filtering the colour image through a striped colour filter. On playback two line scanners are used to simultaneously scan adjacent luminance and encoded chrominance regions to provide the desired information simultaneously. A decoding signal is used to decode the encoded chrominance information and derive colour-difference signals.

Patent GB-2007158-A (GB)
Title: Forming a Resist Pattern on a Substrate
IPC: H01L21/302
Filed: 1978-10-19
Abstract: A method of forming a resist pattern on a substrate by the contamination resist technique involves forming a resist pattern 6 on the surface of a substrate 11 by selectively exposing the surface to a focussed electron beam 2, the resist pattern 6 being built up in thickness by the beam from an initial thin layer 5 of a suitable substance e.g. a silicone oil present on the substrate surface as an incidental or deliberately applied contaminant. The thickness of the pattern (and hence indirectly its line width) is monitored as it is being built up by monitoring electron scattering from the vicinity of the point of impact of the beam on the resist. In the preferred embodiment this is achieved by supporting the substrate 11, which is a thin metal film, on a thin non- backscattering member 12 of carbon, and measuring the number of electrons per unit time entering an aperture in a plate 14 on the opposite side of the substrate 11 to the beam 2. A detector 9 controls the electron beam source 8 in accordance with the measured number of electrons. <IMAGE>

The first and last stages 7 comprise, a flip-flop 8 and an OR gate 13, and a flip-flop 8 and an AND gate 10 respectively. A set input 11 and a reset input 14 of the flip-flop 8 are connected to the output of the AND gate 10 and the output of the OR gate 13 respectively, while the set input 11 of the flip-flop 8 of the stage 7 of the low-order bit position is a counting input 6 of the digit-analog converter. First and second inputs of the OR gate 13 of each intermediate stage 7 are connected to the outputs of the AND gates 10 of the (i+1) and (i+p + 1)th stages 7, respectively. First, second and third inputs of the AND gate 10 of the ith stage 7, beginning with the p + 1)th bit position, are connected to a reset output 12 of the flip-flop 8 of the same stage 7, to the set output 9 of the flip-flop 8 of the (i-1)th stage 7, and to the set output 9 of the flip-flop 8 of the (i p 1)th stage 7, respectively.

Title: Water-flow heaters
IPC: F24H9/20
Filed: 1978-11-08
Abstract: Resistance wire formed into a coil 12, 13, 14 with spaced turns of helical shape is housed in a cylindrical duct. In use an electric current passing through the wire heats water flowing through the duct. The coil (12, 13, 14) is located against lateral movement by engagement with the wall of the duct, so shaped that only spaced parts of the coil can touch the wall. This allows water to flow round much of the coil and prevents local overheating. The wall of the duct may have longitudinally extending grooves (27), the coil touching only the ribs (28) between the grooves. The duct may be formed from two plastic mouldings, one of which may define part of each of two separate ducts; that moulding (29) may be housed inside the other moulding (15). A bimetallic strip 54 controls a switch to prevent overheating. The strip is also moved by water flowing through aperture 43 so that heating current only flows when water is flowing through the heater. Contacts 48, 49 control a further switch for the heating current. <IMAGE>

Title: Pal system colour video signal recording
IPC: H04N9/84
Filed: 1979-01-05
Abstract: A Pal system colour video signal recording system includes first separation means 11 for separating the luminance signal from an input PAL video signal and means 12 for frequency modulating the separated luminance signal. A second separation means 15 separates the carrier chrominance signal from the input signal and supplies the separated signal to a signal processing means 16, 21 which converts the frequency of separated signal to a band of lower frequency than the frequency modulated luminance signal. The signal processing means 16, 21 shifts the phase of the frequency-shifted carrier chrominance signal by 90 DEG C during each successive horizontal scanning period during each alternate pre-determined period, such as each alternate field scanning period, and produces no phase shift during each successive predetermined period. Recording means 14, 25, 26a, 26b multiplexes the frequency modulated luminance signal and the carrier chrominance signal from the processing means 16, 21 and records the resulting multiplexed signal on successive parallel tracks 35a, b, c, d on a recording medium 27 in the form of side-by-side tracks alternately carrying a phase-shifted carrier chrominance signal and a non-phase-shifted carrier chrominance signal. <IMAGE>
