Abstract: 985,945. Transistor pulse squaring circuits. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. May 28, 1963 [May 28, 1962], No. 20474/62. Heading H3T. An amplifier-limiter comprises a pair of transistors X2, X3 having their emitters coupled by a capacitor C5 and separate emitter resistors R7, R9 through which substantially equal currents are arranged to flow under all signal conditions, the signal waveform being applied to the base of one of the transistors X2, for example through a grounded base buffer amplifier X1 (Fig. 1). Negative excursions of the signal cut-off transistor X3 and the capacitor C5 receivers a charge which is of the same value as when positive excursions of the signal cut-off transistor X2. The output waveform from transistor X3 then has an equal time spent on positive and negative voltage levels. The collector of transistor X3 is directly coupled to the base of transistor X4 and transistors X4, X5 have a similar action to transistors X2, X3. The output of the circuit is taken from an emitter follower X6. In Fig. 2 (not shown), the signal excursions fed to the bases of transistors X2 and X4 are limited by a capacitor in series with a pair of clipping diodes and Fig. 3 (not shown) includes additional biasing networks for the diodes to overcome the problem caused by the leakage current of the capacitors. Fig. 4 shows a transformer TR coupled emitter follower X1 feeding the bases of transistors X2, X3 in push-pull and the outputs of this pair feed a similar pair X4, X5.

Abstract: 1,195,101. Weighing electrically. BLH ELECTRONICS, Inc. May 5, 1967 [June 17, 1966], No. 21003/67. Heading G1N. A transducer measuring aircraft weight is supported inside an axle 21 Fig. 9, of an undercarriage and comprises a load sensor, 46, with a deformable tubular port, 46c, to the inside surface of which part are bonded resistance strain gauges, 39<SP>1</SP>, which sensor is deformed by shear forces transmitted via collets 44, 45 and collers 50, 51. The collets Figs. 11 and 12 are formed from flexible, dished, metal members such as 44a, 44b arranged in concave, confronting relationship and welded at the outer edges of arcuate parts and may be expanded radially, by axial compression of the inner edges such as 44c, 44d, to engage the inner surface of the axle. Collet nuts 63, 65 in screw-threaded engagement with respective collars effect this compression against shoulders 50a, 51a, being secured by lock nuts 64, 66, Keys 57, 58 engage keyways such as 44e to maintain a given angular disposition of the collets. The strain gauges comprise a pair at each of diametrically opposed points on the interior surface of the sensor, the gauges of each pair (39a, 39b) Fig. 4, (not shown), being disposed mutually perpendicularly and at 45 degrees to the longitudinal axis of the sensor, like disposed gauges being connected in diagonally opposed arms of a bridge circuit. Thus a voltage output represents the vertically directed components of shear. Load from the collet 45 is transmitted to the load sensor 46b through a pin, 49, positoned beside the collar 51 by a stack of washers of two dissimilar sizes arranged in axial alternation Fig.16, (not shown). These engage alternately the pin and the collar so that a predetermined bias deformation may be applied to the sensor by alternating the relative radial dispositions of the washers, thus effecting compensation for the weight of the wheels. An alternative three-armed form of a collet member is illustrated at Fig. 13 (not shown). It is stated that a centre-of-gravity display is one of the instruments, Fig. 18, (not shown).

[Class 39 (i)] [Also in Group XXXVIII] A photo-electric cell for reproduction of push-pull sound records has in a single envelope two electrically separate electrode assemblies A, B, each consisting of a curved cathode 2, constituting a portion of a hollow cylinder and a rod or wire anode 3 located in the curve of the cathode, the two assemblies being mounted in the envelope so that the axes of the cylinders coincide with the longitudinal axis of the envelope. Preferably the effective portions of the anodes are coaxial, the rod or wire forming the anode remote from the stem 4 which supports the assemblies being cranked at 5 to separate it from the other anode and covered with insulation 6, such as a glass tube, to prevent it picking up electrons from the other cathode; Alternatively, the remote anode may pass behind the other cathode. The cathodes may be connected to opposite ends of a transformer winding, the centre tap of which is connected to the negative pole of a battery and the anodes are connected to variable tappings on separate resistors connected in parallel across the battery. The Provisional Specification describes a modification in which the assemblies are arranged side by side upon the stem.
