Abstract: 1,233,401. Printed circuits. ELECTRO CONNECTIVE SYSTEMS Inc. 6 June, 1968 [29 June, 1967], No. 27041/68. Heading H1R. In a method of producing a printed circuit from a metal foil clad laminate by a photo-etch process, the foil is coated with a light-sensitive etchant resistant material, the material is printed with a desired circuit pattern exposed to light and the light exposed or unexposed portions of the etchant resistant material removed by developing thereby leaving only the circuit pattern coated with etchant resistant material. In a first example, a copper foil bonded to a polyamide-polyimide film, glass, ceramic, ureaformaldehyde and melamineformaldehyde condensation products, fluorocarbons, cellulose acetates or nylon insulating backing is fed into a dark room where a lightsensitive material in the form of a film forming liquid is applied. The liquid sets on drying and is such as to become soluble in a developer when exposed to light, whereas unexposed film is not soluble. After drying the coated film is passed through a rotary printer where the desired circuit pattern is printed with a pigmented printing ink on the light-sensitive coating. The coated and printed foil then passes out of the dark room past a light source where the unprinted areas of the light-sensitive material are exposed. These exposed portions are chemically changed by the light and are removed by passing the foil through a bath of developer such as a weak alkaline solution. The foil is then etched to remove the foil not covered by the etchant resistant material and printing ink. Finally, the printing ink and light-sensitive coating are removed by passing through appropriate solvents. Alternatively, the light-sensitive material may be removed by exposure to light and developing. In a second example, the ink is printed on those portions of the resist coating overlying the portions of foil to be subsequently removed. After exposure to light the ink is removed and the photo-resist is then developed which removes those portions not exposed to light.

[Also in Division F2] In a fuel element stringer for a nuclear reactor whose fuel elements together with a bottom fitting 10 are threaded on to a central tie rod 15 and are retained thereon by a retaining device secured around the rod beneath the fitting, the retaining device comprises an open ended tubular collet 11 formed with two or more longitudinally-extending slits in the wall thereof and which are distributed around the circumference of the collet, each slit extending from one end of the collet over a substantial portion of the length of the collet, and a retaining sleeve 21 slidably mounted on and surrounding the collet and movable axially therealong. The sleeve co-operates with the external surface of the collet so that when the sleeve is moved into an operative position surrounding the slitted end of the collet the sleeve presses the side wall of the collet between the slits radially inwardly to cause engagement thereof with an external abutment formation or formations on the end of the tie rod whereby axial withdrawal of the collet from the tie rod is positively prevented. The sleeve when moved axially along the collet from the operative position into the inoperative position allows the portions of the collet side wall between the slits to be moved radially outwardly and disengaged from the rod abutment formation or formations so that the collet can be removed from the rod. As shown, the sleeve is provided with tabs 27 which are bent inwardly to lock the sleeve in the operative position, and the collet is formed with a skirt 17 which extends through and is retained in a sleeve 12 forming part of the stringer 10.

Heading G1N. In a temperature measuring apparatus in which a plurality of thermocouples 28 are connected via individual measuring bridge circuits 1-4 to a magnetic amplifier 7 the amplifier 7 is arranged to sum the thermocouple signals and temperature sensitive elements 27 are provided in each bridge circuit to compensate for variations in ambient temperature. After initially balancing bridges 1-4 and circuit 6 thermocouple signals produced by unbalance of bridges 1-4 are applied to control windings 37-40 of amplifier 7 the summed output of which is passed to phase-sensitive amplifier 8 to produce a D.C. output proportional to the sum of the thermocouple outputs. A mean valve is obtained by connecting a voltage divider between the amplifier 8 and a meter. To determine the deviation of the total or mean signal from a set point each bridge 1-4 is adjusted for the desired set-point so that either zero signals when the measured thermocouple e.m.f.'s are equal to the set point valve or signals representing the deviation from the set-point are applied to control windings 37-40. By varying the signal from circuits 5, 6 in control winding 44, opposing the signals in 37-40, the apparatus acts as an indicator of absolute sum i.e. when the signal on winding 44 is zero or an indicator of the deviation of a sum from a set-point determined by set resistor 5. The apparatus may be used as a temperature comparator by interchanging the junctions 29-30, 31-32, 33-34 or 35-36.

Abstract: 1304529 Automatic speed control FORD MOTOR CO Ltd 13 Jan 1970 1499/70 Heading G3R In a speed control system for a vehicle driven by an internal combustion engine, an actuating error signal is formed by combining signals representing the actual and desired vehicle speeds. The desired speed signal is obtained by setting the actual speed signal into a memory when the actual speed equals the desired speed. In the system shown in Fig. 1, a pick-up 12 produces A.C. of frequency proportional to the vehicle speed. This A.C. is converted to a steady voltage Vs by a converter 14 and filter 16 before being fed to a comparator 18 to which a voltage V R  representing a desired set speed is also supplied. A setting switch 22 receives a voltage corresponding to the desired speed at a time when the latter is equal to the actual vehicle speed. The signal Eg from the comparator 18 is amplified and compared in a second comparator 26 with a signal V #  which is a function of the engine throttle position. Thus an actuating error E  a  is produced, and this signal, after amplification, is used to control valves 30 controlling a servomotor 32 which operates the throttle, thereby adjusting the vehicle speed. Whilst the part of the system designated as the "speed loop" is capable on its own of controlling the vehicle speed, the addition of the "throttle loop" improves the control accuracy and reduces oscillation and hunting effects. In operation, the driver of the vehicle actuates the atutomatic speed system by pressing a first switch. This automatically sets the desired speed at the actual speed of the vehicle at the time. A second push button rocker switch can also be operated to alter the desired speed setting automatically in either direction, this switch being held down until the desired speed is reached. In the embodiment described, the set speed is determined by the voltage across a capacitor which is connected to the control electrode of a very high input impedance solid state amplifiers, which preferably takes the form of a field effect transistor. The speed control system is only operational when this transistor is rendered conductive. In particular, the system is deenergised if the vehicle speed is below a certain value, or if the error signal becomes large. The system is also blocked, by way of the stoplamp switch, when the brake pedal is depressed. The actual throttle control is by a diaphragm which forms one wall of a chamber which can be selectively connected by solenoid-controlled valves to sources of vacuum or atmospheric pressure, Figs. 5-6, (not shown). The circuits corresponding to the diagram of Fig.1 are described with reference to Figs. 2- 2a, whilst modifications to the circuits of the input to the frequency-voltage converter 14 and the throttle position transducer 34 are indicated in Figs.3, 4 respectively, (not shown).
