Abstract: 1,232,115. Integrated circuits. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 27 May, 1968 [31 May, 1967], No 25160/68. Heading H1K. [Also in Division H3 A mechanical resonator associated with means for oscillating it is firmly attached at one end to a semi-conductor integrated circuit block which is connected to another such block by the or another resonator. In one example the connecting resonator serves also as an electrical connection. Each resonator may have one or more piezo-electric or electrostrictive transducer elements associated with it. Thus, as shown in Fig. 4, a number of beam resonators 7 extend between two circuit blocks and are interconnected mechanically by a strip 8. An electrical signal is fed in via piezo-electric transducer 5 and an output signal derived from a similar transducer 6 mounted on the other end beam to form an electromechanical filter. A resonator may be set into torsional vibration by out of phase signals applied via transducers disposed on opposite sides of the centre line of a beam. The beams are preferably formed by electroplating or vapour depositing gold interconnections between groups of circuit elements formed in and on a semi-conductor substrate and then removing semi-conductor material by photo-resist and etching steps to leave isolated blocks with unsupported mechanically resonant interconnections extending between and from them.

Abstract: 1,233,915. Analyzing gases. MINISTRY OF DEFENCE. July 30, 1969, [July 2, 1968], No.31486/68. Heading G1N. In apparatus for measuring the concentration of a gas in a sample of air, the air sample is first subjected to a physical or chemical process specific to the particular gas to produce particles, is then ionized, e.g. by a radio-active source, and then passed, via a restricted orifice, into a charging chamber, the orifice and walls of the chamber having different potentials so that all the ions of one sign are swept into the chamber to set up a unipolar plasma on which the particles are charged by collisions, the quantity of charge of the particles being measured, e.g. by an electro-meter to indicate the concentration of gas. To separate the charged particles from the unipolar ions, they are subjected to an electrostatic barrier, such that only the charged particles are allowed through. The charged particles may be collected by a wire wool filter connected to earth via a resistor. If the air contains sulphur dioxide, it is subjected to U. V. light so that sulphur particles are formed, and if the air contains ammonia or a primary amine, it is subjected to hydrochloric acid to produce particles. The apparatus for charging the particles by setting of a unipolar plasma of ions is as described and claimed in Specification 1, 105, 604.

Abstract: 1,238,448. Textured polyester slab yarns. SOC. RHODIACETA. 18 Feb., 1969 [19 Feb., 1968], No. 8861/69. Heading B5B. [Also in Division D1] Each filament of bulky continuous multifilament textured polyester yarns (or staple fibres obtained therefrom), particularly polyethylene terephthalate yarns, comprises at least three types of zones of different mean diameter, the finest zones having the highest crystallinity and the greatest molecular orientation, the thickest zones having the lowest crystallinity and the least molecular orientation, and the intermediate zones (whose mean diameter is between the mean diameters of the finest and the thickest zones) having a crystallinity and a molecular orientation between those of the finest and the thickest zones. Each filament furthermore possesses transverse grooves of attenuated relief at least in the thickest zones and has a non-spiral three-dimensional crimp. The thickest parts of the filaments may be unoriented and relatively non-crystalline. The thinnest parts of the filaments may have a crystallinity index between 30% and 60% and an angle of molecular orientation less than 40 degrees, and the thickest parts may have a crystallinity index less than 30%, and an angle of molecular orientation of about 90 degrees. The yarns of the invention may be produced by partially stretching an undrawn multifilament yarn of synthetic thermoplastic material in at least two stages, of which the first is carried out while the yarn is in contact with a crackpromoting agent, the degree of stretch in the first stage being greater than in the second, and subsequently heat treating the stretched yarn in a relaxed state. The crack-promoting agent may be of any known type, such as a monohydric alcohol, a glycol, dimethylformamide, kerosene, perchlorethylene, a polyoxyethylenic liquid, or pyridine. In an example, a 30-filament polyethylene terephthalate yarn is stretched at a stretch ratio of 2À1 while passing through a bath of 25% aqueous ethanol at 35 C. The yarn is then stretched at a stretch ratio of 1À2 in air between the first set of stretching rolls and a second set of stretching rolls, and thereafter heat-treated in the relaxed state while immersed in water the initial temperature of which is gradually raised to 100 C. The yarn is then dried under tension with free access of air, and finally heated for 5 minutes in an oven at 180 C. The heat treatment in the relaxed state can be carried out in a continuous manner immediately after the stretching stages or as an independent operation on the yarn or on a fabric, e.g. a woven fabric, made therefrom, and may for example be combined with a dyeing treatment of the woven fabric; yarn according to the invention has high dimensional stability and high apparent volume. The yarns can be converted into knitted fabrics.

Abstract: 1,251,754. Peak voltage measurement. E.I. DU PONT DE NEMOURS & CO. Jan. 31, 1969 [Feb. 9, 1968], No.5475/69. Heading G1U. A system for measuring the maximum amplitude of a pulse of energy, such as a light pulse 8, incorporates a transducer 9, such as a photomultiplier, which produces an electric signal proportional to the pulse, coupled to an operational amplifier 19 which has an automatic range changing system 22 coupled in feedback relation to it, by which the output from the amplifier is attenuated in a given ratio whenever the amplifier output reaches a predetermined value. A first indicating device 26 is coupled to the range changing system to indicate whenever the amplifier output reaches the predetermined value. A memory 28 is coupled to the amplifier output via diode 27 and retains the maximum amplitude of the output signal following the last attenuation, the amplitude being indicated by a second indicating device 33. The output from the photo-multiplier 9 takes the form of an uni-directional current pulse whose amplitude depends only on the size of the input light pulse 8 and the photo-multiplier supply 10. This current is smoothed by a filter circuit 11 which incorporates transistor switches 16-18 which are progressively switched in as the current increases to shunt the resistors 13, 14, 15, so that resistance is decreased as the current increases, so that a high voltage drop is not developed across the filter. The filter output is passed to the amplifier 19 whose output controls a pulse generator 23 to release a pulse when a given amplitude is reached. This pulse is applied to logic circuit 24 which switches the controlled resistance circuit 25 to reduce the amplifier gain by e. g. a factor of 10. The pulse also switches on the transistor 29 to discharge the capacitor 28 which normally is fed by the amplifier output via the diode 27. Indicator 26 monitors the condition of the range changing circuit, while amplifier 32 and indicator 33 detect the voltage on the capacitor 28. A switch 30 enables the capacitor to be discharged between measurements, at which times the attenuator circuit must also be returned to zero setting. The amplifier 19 is also provided with a feedback circuit 27 designed to eliminate the effect of the standing current in the photo-multiplier which appears in the absence of input pulses. This circuit detects and stores the amplifier output in the absence of input pulses to the photomultiplier and feeds back an appropriate current to cancel the standing current when input pulses occur. The system is calibrated by irradiating the photomultiplier with the output of a lamp of known magnitude and adjusting the supply 10 until the appropriate reading is achieved.

Rotation of shaft 24, Fig.2 via gearing 26-30 alters a blending meter or balanced valve device 33 selecting e.g. either of two fuels or one of three mixtures thereof, the exact position of the shaft being determined by roller 36 entering a notch 34 in rotatable disc 32. The roller rides on the disc edge when the blend is changed and its movement out of the notch turns crank 42, 38, 44 and lever 48 to lower rod 52 to switch off, via a differential mechanism, a micro-switch controlling the pump motor, the switch only being switched on again by the main on/off control. Levers 55 are also turned to disengage contrate gears 58 from the calculating apparatus to prevent damage during blend selection. In Fig.6 rotation of notched blend selection disc 70 lifts roller 88 on to the disc edge and via sprung lever system 92, 98, 100, 120 raises nose 122. The pump on/off switch shaft 126 carries cam 128 with stops 130. When the pump is switched off, the cam permits nose 122 to move upwardly and therefor disc 70 to be rotated. If the roller 88 does not properly engage notches 86, then nose 122 engages stops 130 and prevents the pump being switched on. Cams 132 also act on arms 136 to disengage the contrate gears when shaft 126 is rotated to the off position.
