Title: Transistorized noise suppression circuit
IPC: H03G3/34
Filed: 1960-04-12
Abstract: 876,128. Transistor radio receiving circuits. TESLA, NARODNI PODNIK. April 12, 1960 [April 21, 1959], No. 13022/60. Classes 40(5) and 40(6) A transistorised radio receiver is muted in accordance with the noise level. Noise is taken from a discriminator circuit by means of a condenser C2 passing only higher frequencies and is amplified by a transformer-coupled noise amplifier TS1. The output is rectified by diode D1, which is given an adjustable delay bias by means of a potentiometer comprising resistors R4, 5 and applied as a positive bias to a transistor TS2. The transistor TS2 is normally biased conductive by a negative bias derived over resistor R6 and is in the emitter circuit of a further transistor TS3 which functions as an audio amplifier, the arrangement being such that when a sufficient noise voltage is present, i.e. in the absence of an adequate signal, the transistor TS2 is biased non- conductive and so interrupts the supply to the transistor TS3.

Patent GB-131987-A (GB)
IPC: G01C19/38
Abstract: 131,987. Harrison, G. B., and Rawlings, A. L. July 31, 1918. Gyroscopic compasses.-In gyro-compasses controlled by transfer of liquid from one part to another the liquid-containing vessel is so shaped-that the distribution of the liquid will be practically uneffected by the rolling of the ship and yet sensitive to accelerations due to changes of speed and course so as to give the required ballistic deflexion. In the construction shown, the liquid is contained in two boxes 8 carried by a framework 9 pivoted on horizontal bearings 10 of a phantom or following element 3. The frame 9 is constrained to tilt with the casing 1 containing the gyro wheel by an arm 11 and a flexible joint 12; one form of joint, shown in Fig. 3, consists of a roller 12 fitting within a channel 16 of the casing 1; another form, shown in Fig. 4, consists of a flat spring 15; the flexible joint allows a small movement in azimuth. The connexion to the gyro casing 1 is at a point a little to the east of the centre so as to produce a damping effect. The boxes 8 are connected by a pipe 13, which is of such a cross-section compared with the size of the boxes and of such a length that the natural period of oscillation of the liquid is rather more than twice the period of the ship. If necessary, the pipe is coiled or doubled back. The friction of the liquid in the tube produces a phase-difference between the force due to the rolling of the ship and the flow of liquid. In order to be able to vary the ballistic deflexion, means are provided for varying the free area of the liquid in the boxes. A sliding piston is provided in the pipe 13 for indicating the level.

Abstract: 377,325. Binding and covering the edges of sheet material ; embossing. WALPOLE, G. S., 14, Howick Place, London, and BROWNLEE, J. D. O., 125, Kent House Road, Beckenham, Kent. May 5, 1931, No. 13261. [Class 83 (iv).] Shearing adjuncts.-A press for securing metal rims to sheets or cards, such as show cards or calendars, is provided with means for severing the rim strip to size, so as to enable cards &c. or bundles thereof of any length to be rimmed without the necessity of using standard lengths of rim strip. The movable press member 2 is reciprocated in guides by pairs of vertical toggles 4, 5 and horizontal toggles 7, 8 from a draw bar 10, which may be operated either by a hand- or foot-lever alternatively or by a motor. The bar is normally pressed upwards by a spring 12. The front edges of the press members 1, 2 may be rounded so as to prevent marking- of the work and may be provided with projections or other patterns for decorative purposes and also to assist in securing the strip. Cutting blades 14, 15 for severing the rim strip are mounted at one or both ends of the press ; one end of the press may be provided with a detachable or adjustable stop 13 in place of cutters. In a modification the edge of the bed of the press may serve as the fixed cutter. The blade 15 may be stepped or inclined so as to allow the strip to pass therethrough while forming a stop for the edge of the card. A rim strip of channel secton is placed on the card and the parts may then be pushed against the stop 13 so as to align them at this end. The press may then be operated to clinch the strip on the card and the work then transferred to the other end of the press to sever the projecting end of the strip. The pressing and severing operations may alternatively be performed simultaneously. When using strips having tongues or indentations, the strips are placed on the cards, clinched thereto, and severed in turn at each end by turning over the work. In order to use the press for cards up to double the width of the press or to obtain registration between the work and a desired part of a length of patterned strip the stop 13 is made detachable or pivoted by an eccentric hole on a screw on the bed, so that on releasing the screw the stop may be turned into inoperative position. The strip may be painted, lacquered or varnished.
