Abstract: 1,238,198. Automatic control. FOXBORO CO. Nov.21, 1968 [Dec.1 1967], No.55282/68. Heading G3R. Signals dependent on a process variable, e.g. for controlling the variable, are transmitted through an amplifier from one area to another and the rate of energy transfer to one of the areas, which is hazardous, is limited by applying the signals to a low input impedance each end of which is connected through a high impedance to an input terminal of the amplifier. In Fig.1 the current through a low resistance 30 from a limitedvoltage, constant-current source 20 is varied by a transducer 14 in response to variations of a process condition such as temperature, pressure, or flow in a dangerous area 12. Resistance 30, which is located in a safe area 13 is connected through high resistances 31, 32 to the input of an amplifier 35 so that excessive energy cannot be transmitted through the resistance network to the dangerous area under fault conditions. The voltage of the constant current source 20 which is supplied by a bridge rectifier is limited by a Zener diode. The output of amplifier 35 operates an alarm 41, a recorder 42 and a controller 44 the output of which is applied through a second, similar, energylimiting resistance network 50 associated with an amplifier 55 which controls a valve 15 automatically regulating the process variable.

Abstract: 1,257,143. Sensing records. NATIONAL CASH REGISTER CO. 8 June, 1970 [30 June, 1969], No. 27589/70. Heading G4M. Data are represented by the transitions between contiguous indicia having at least three different characteristics, e.g. red, white and black colour bands, no two adjacent indicia being the same, and the indicia are sensed serially to provide signals representing the data. A first set of transitions may represent binary 1 and a second set of transitions, e.g. the reverse order transitions, may represent binary 0. Ternary digits may also be represented by sets of transitions. In the 3-colour binary embodiment shown, a dichroic mirror splits light reflected from the record into red and green components sensed by detectors 74, 72 respectively. The minimum signal level from each detector is detected and stored at 108, 112 and a negativefeedback circuit 110, 114 compensates for light, power supply and temperature variations. A generator 126, 116 sets a threshold level halfway between the minimum signal level from 108, 112 and the peak signal from the sensor 74, 72 and the outputs of detectors 74, 72 are digitized by reference to the threshold levels in comparators 128, 118 which may be high gain saturating amplifiers. The outputs of 128, 118 are used to update the minimum detected signal levels at 108, 112. Output from comparator 128 representing a signal below the threshold corresponds to sensing of a black band and output from comparator 118 representing a signal above the threshold corresponds to sensing of a white band. The outputs of detectors 74, 72 are subtracted by a differential amplifier 132 and the result is compared at 134 with a threshold level derived from the generators 126, 116 at 136 to produce an output representing a red band whenever the output of amplifier 132 exceeds the threshold. The outputs 266-268 may be processed into a series train of binary signals by the circuit disclosed in Specification 1,257,142.

Abstract: 1288648 Pipe joints SERVOTOMIC Ltd 3 Nov 1970 [13 Dec 1969] 60891/69 Heading F2G In a method of pipe jointing the pipe end is received in a socket with an interference fit and secured with a curable adhesive. As shown, the pipe 14 is knurled or screw-threaded over a portion 15, leaving plain end portion 17 which provides a lead-in for inserting the pipe. Surface protuberances (19) (Fig. 4, not shown) of the knurling are upset by the sleeve bore surface (20) when pipe and sleeve 10 are telescoped together, which is done manually, but the outside sleeve surface 24 and the pipe bore are not deformed. Prior to inserting the pipe, the co-operating surfaces of the sleeve and pipe, which may be of bare or plated steel, are degreased by applying a primer and coated with a curable adhesive such as a polyester or an acrylic resin which is not inhibited from polymerizing, and will not be subsequently depolymerized, by the pipe and sleeve material. After telescoping the pipe and sleeve, the adhesive fills the gaps (23) (Fig. 4, not shown) between the upset protruberances. In modifications of the method, either or both the pipe surface and the sleeve bore may be knurled or threaded. The method may be adopted in the installation of a system of pipework such as a central heating system (Fig. 5, not shown). The mechanical strength of the joint enables the installation to proceed without the delay of waiting for the adhesive in each joint to cure before the next joint is made. Other applications include joining a pipe portion to the hollow spigot of a valve.

The beams are deflected vertically by a part-cylindrical lens 5 so as to enter along a focal line an acousto-optical deviation cell 1 at a suitable angle which is the same in the horizontal sense for all the beams. The cell 1 produces a horizontal refraction of the beams dependent on the frequency of ultrasonic waves passed longitudinally through the cell by an acoustic microwave generator 11, the frequency being controlled by the decoding means 13 through a synchronizing circuit 12. The beams then pass to a part-cylindrical lens 6 through which they pass as parallel beams in the forms of the selected character, at a position which is determined in the horizontal respect by the said frequency. The beams then pass through a reducing optical telescope 7, 8 and are projected on to the photosensitive surface of a recording medium 9, the said frequency determining the position of the character in the line. The medium 9 is moved continuously for line spacing under the control of the circuit 12 and is arranged at an angle slightly inclined to the deviation plane of the cell 1 so as to compensate for its movement and have the lines formed laterally across it.
