Patent GB-1250246-A (GB)
IPC: C21D9/08
Filed: 1969-06-04
Abstract: 1,250,246. Colour facsimile systems. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 4 June, 1969 [4 June, 1968 (4)], No. 28368/69. Heading H4F. In a colour facsimile system in which a linesequential output is produced by a transmitter and at the receiver is applied to a lamp in front of which is rotated a multicolour filter to appropriately colour the light beam, phase control pulses are transmitted to the receiver at times corresponding to a selected one of the lines making up the sequence. As shown, Figs. 1a and b, in the transmitter a colour original is placed on a drum 1 which is rotated by a motor to produce the line scan. A pick-up system incorporating a dichroic prism 3 and three photomultipliers 4 is moved along the length of the drum to provide the field scan, and generates red, green and blue component signals which are modulated on to carriers, the resulting signals being applied to a masking circuit which corrects for the density of the original and then to gating circuits 8R, 8G, 8B which produce a line sequential output under the control of ring counter 7 driven by synchronizing pulses one of which is generated by pick up 5 for each revolution of the drum. In the receiver the signal is demodulated and used to control the light emission of a lamp 10 in front of which is rotated a tricolour filter 11. The line scanning system comprises a rotating cranked light guide 12 feeding a circular array of optical fibres 13 which are transposed to form a linear output scan. The colour output lines are recorded on a colour film which is moved past the linear part of the scanning system to provide the field scan. The output of the ring counter 7 which controls the red channel gate 8R is also applied to the input of a monostable circuit 33 which generates a phase control pulse at a selected position in each complete sequence of lines. The pulse is used to modulate a carrier and initially only this signal is transmitted and is received by an Automatic Start Stop circuit 14 whch switches on the receiver circuits. Clutch 18 is engaged and the phase detector 19, 20 driven by the line scanning system generates one pulse for each sequence of lines. These pulses are compared with those received from the transmitter and if coincidence is not achieved clutch 18 is disengaged and on the next received pulse reengaged, a timing correction circuit being included to achieve synchronism. When three successive pulse coincidences are achieved the transmitter is informed by sending an 800 Hz oscillation. The phase signal modulator at the transmitter is then cut off, the field scan is started, and the line sequential colour signals are transmitted. Synchronism is maintained since the motors in the transmitter and receiver are fed from crystal oscillators. Suitable circuits for the ring counter and gating circuits are described Fig. 3 (not shown).

As shown in Fig. 1, the apparatus comprises an injection cone 12, a blow-mould 13 and a plunger 14. Parison 11 is injectionmoulded on core 12 and transferred on it to blow mould 13. Plunger 14 is released to press on and deform the bottom of parison 11 under pressure of spring 15.

Air is supplied through duct 122 and the radial passages on retraction of outer core sleeve 121. When the parison is expanded to contact the mould walls, the air pressure is sufficient to lift plunger 14 against spring 15 to its position in the mould wall where it is then held by piston 17 of control cylinder 16 and guide sleeve 171 attached thereto by means of pressure medium supplied through conduit 161, which raises piston 17 so that sleeve 171 abuts head 143.

Conventional additives such as delustrants, pigments, heat or light stabilizers and M.W. regulators may be added before or duringreaction, e.g. TiO 2 , ZnO, carbon black or copper phthalocyanine. The products may be melt spun or moulded. Reference is made to Specification 1,252,073 which relates to a similar process wherein no preformed polyamide is used.

These differences between adjacent signals pass through sealing circuit 18, time-controlled switch 19 to integrating circuit 21 and after a predetermined number of input signals have been admitted the switch 25 is operated to a storage circuit 26 the output of which is displayed at 34. The sealing circuit is chosen so that the output is the standard deviation of the input signals. Switches 13, 14 and 19 are controlled by the same timing signals applied to input 12. The mean deviation of the signals from an assumed mean may also be derived by adjusting each input against a reference potential 35 in circuit 27 such that a signal equal to the assumed mean will provide an output from circuit 27 equal to reference potential 35. This output passes through a sealing circuit 28 and a switch 29, in synchronism with switch 19, to an integrator 30 which integrates the difference between the output of sealing circuit 28 and reference potential 35 to give a signal representing the deviation from the assumed mean.

When the liquid-level in evaporator 1 reaches a predetermined lower level, the float 24 and linkage 27 automatically make the supply of heat to the evaporator inoperative, and the valve 21 in the salt water supply pipe 20 is opened. When the liquidlevel in evaporator 1 reaches a predetermined upper level, the valve 21 is automatically closed and the supply of heat to the evaporator is re-established. The apparatus may be disposed outboard at the stern of a boat, condenser 2 and the lower end of pipe 20 being immersed in the sea. Evaporator 1 may be heated by hot combustion gases from a volatile fuel burnt at a wick in heater 8, the flow of hot gases to or away from the evaporator being controlled by dampers 12. The heating means may be a gas burner provided with a pilot flame. In a modification, a magnet is mounted on the float 24, and the valve 21 and the heating means are controlled electrically.

Abstract: 1324511 Positioning systems INTERNATIONAL COMPUTERS Ltd 1 Jan 1971 [17 Jan 1970] 2358/70 Heading G4H In a positioning system the magnitude of the difference between the required position and actual position of a member 4 is compared in comparator 24 with a signal representing a predetermined function of the velocity of the member to first accelerate and then decelerate the member towards the required position, the predetermined function being modified as the member nears its required position. As described for positioning a head 4 over the required track of a disc 1, a grating 10, 11 sensed by photo-cells 12 is moved with the head, the photo-cell output being decoded to give a signal on lead 17 representing the direction of movement and pulses on lead 18 representing increments of movement. The signals on lead 18 as well as being counted in counter 19 for comparison in an error magnitude detector 21 with the required position are counted for predetermined time intervals determined by sampling pulses from slow pulse generator 27 in counter 29 to give a count representing the velocity. This count results in a number approximately equal to its square with a sign determined by the direction of movement being fed from a velocity look-up network 33 to the comparator 24, the comparator giving initially a forward accelerate signal on lead 37 when the signal from detector 21 is greater than the output of velocity look-up and then a reverse accelerate signal on lead 38 when the output of velocity look-up network exceeds the magnitude of the signal from detector 21. If initially the head is to be moved in the reverse direction error magnitude detector 21 comparing the required and actual positions gives its output in complementary form and a signal is first given on lead 38 followed by a signal on lead 37. As the head nears its desired position a near zero detector 41 is energized which results in (1) the velocity signal being sampled more frequently under the control of generator 26 to enable more accurate positioning and (2) the output from velocity look-up network 33 to comparator 24 being modified to decelerate the head slightly earlier than would otherwise be the case.
