Title: Improvements in and relating to apparatus for working articles with energised beams
IPC: B23K15/02
Filed: 1963-12-24
Abstract: 1,065,060. Welding and cutting by fusion n  making electrical circuit boards. UNITED AIRCRAFT CORPORATION. Dec. 24, 1963 [April 19, 1963], No. 50892/63. Headings B3A, B3R and B3V. [Also in Divisions H1 and H4] In electron or laser beam working or welding apparatus, e.g. for welding the tabs 12, Fig. 1 (not shown), of electrical components to contact pads on a circuit board 10, the beam is automatically directed to the right working point by means of a control signal derived by the emission, e.g. of light, from the working point. The tabs may be coated with a fluorescent dye and irradiated with ultra-violet light, the emitted light passing either to an image converter tube or to a phototube. If necessary a light filter is interposed to differentiate the control light from light emitted by the material of the baseboard. Where an image converter tube is used, Fig. 3 (not shown), a scanning of the image of the workpiece takes place in the converter tube which produces bursts of light corresponding to the tab positions, these bursts of light passing through a mask on to a phototube. The scanning in the image converter tube is in synchronism with a scanning waveform applied to the main deflection coils of the electron beam working apparatus, but the working beam is not switched on. A control circuit responsive to the phototube and incorporating storage and counter circuits halts the scanning of the main deflection coils and produces a D.C. bias signal which is applied to the deflection coils to bring the beam on to the tab at the appropriate moment when the beam is switched on. A function generator is included in the circuit to generate an additional D.C. bias signal for bringing the beam into the centre of the tab. Additionally, the beam is caused to trace a sinusoidal pattern along the tab in the welding operation by means of a further deflection drive circuit. In the alternative embodiment in which the light emitted from the workpiece is passed directly to a phototube, Fig. 5 (not shown), the electron beam, in an unfocused condition, scans the workpiece to produce the bursts of light. The control circuit, which is similar to that in the first embodiment, serves to raise the intensity of, and to focus the electron beam, during the welding operation. Reference is made to the use of a laser beam instead of an electron beam. The circuit board 10 is formed by a substrate having a layer of chromium applied by vapour deposition followed by an electroplated layer of nickel. The metal layers are etched by an electron beam to provide discrete conductive paths.

Title: A cooling system for the working fluid in hydraulic circuits of vehicles
IPC: F15B21/0423
Filed: 1969-10-17
Abstract: 1,239,841. Hydraulic motor control circuits. DR-ING H.C.F. PORSCHE K.G, Oct.17, 1969 [Oct.17, 1968], No.51038/69. Heading F1P. Cooling of hydraulic fluid prior to it being forced by a pump 7 Fig.1 through a line 9 to actuators 10 -- 10"' suitable for closing hatches 12 on an amphibious vehicle is effected by forcing the fluid by a pump 1 past an open temperatureresponsive valve 16 and through a line 22, a radiator 3 cooled by a fan driven by an hydraulic motor 2 in the line 22 and back to the reservoir 5 through lines 23, 24, 38 Fig.2, 34, 35; the valve 17 being normally in abutment with a setting piston 30 in conduit connection with line 9 whereby when line 9 is pressurized piston 30 moves to the right and the valve 17 is moved by a spring 29 to the closed position. In operation and assuming no pressure in line 9 and the fluid to be at the desired low temperature, the delivery line 33 is connected through a port 28 in a sleeve 18 and through a bore 38 in valve body 20 to the return line 34. A temperature rise causes valve 17 to expand against a spring 29 and so displace the: sleeve 18 to a position in which port 28 registers with a body groove 36 whereby pump delivery is connected to the motor 2 and radiator 3.

Patent GB-1479516-A (GB)
Title: Pulse generator with automatic timing adjustment
IPC: H03K3/015
Filed: 1974-11-28
Abstract: 1479516 Synchronizing BURROUGHS CORP 28 Nov 1974 [27 Dec 1973] 51537/74 Heading G4C [Also in Division H3] In a pulse generator for generating a train of pulses at 13, Fig. 3, in-response to a train of trigger pulses a ramp voltage is generated across 20 when a bi-stable flip-flop 11 is set by each trigger pulse and is terminated when the flip-flop is reset on equality of a reference voltage from 19 and the ramp voltage and a circuit, Fig. 5 automatically adjusts the reference voltage level to maintain the duration of the output pules as a constant multiple of the interval between pulses. When the flip-flop is set Q 1 and Q3 turn on to charge capacitor 20. On equality of the reference voltage 19 and the ramp voltage an output from a comparator amplifier 21 resets the flip-flop and Q4 turns on to discharge the capacitor 20 when flip-flop 11 is triggered a counter 39, Fig. 5, provides a hold off delay time of eight pulses before the output from 13 is allowed to be fed to control charging and discharging current sources 25 and 26. The high going output from 11 is inverted at 37 and activates Q5 which causes a 1 ma discharge current from a control capacitor 27 to flow via Q9 until the output from the flip-flop is reset and ends. Then the capacitor 27 is charged by a 3 ma current from Q10 until the next output pulse is obtained from the flip-flop. The voltage across capacitor 27 is fed via emitter follower Q11 to automatically adjust the reference voltage at 19 so as to maintain the mark/space ratio constant such as 0À75T to 0À25T (Fig. 6A, not shown). Under these conditions the net charge change on the capacitor 27 (i.e. 0À75T x 1 ma = 0À25T Î 3 ma) is zero. However if the pulse duration falls the charge remaining across the capacitor 27 will increase as does the overall reference voltage at 35. This causes the time of the ramp necessary to reset the flip-flop to increase to restore the required ratio. Similarly if the pulse duration is too long the charge in charge of the capacitor 27 results in a decrease in the capacitor voltage which shortens the ramp time required to reset the flip-flop. The circuit may be used in magnetic readwrite systems employing double frequency phase encoding where to detect data it is essential that the rectangular timing pulse lasts for a specific percentage of the time interval between trigger pulses in spite of variations in that interval.
