Title: Improved photographic pick-up or disc cutter
IPC: H04R17/06
Filed: 1961-08-03
Abstract: 977,031. Pick-ups and disc cutters. M. DE VRIES. Aug. 3, 1961 [Aug. 13, 1960], No. 28264/61. Heading H4J. A gramophone pick-up or disc cutter has a single stylus holder carrying at one end two styli which are capable of being brought alternatively into operative contact with gramophone record means, the other end of the stylus holder bearing against transducer means when either stylus is in an operative position and being moved out of contact with the transducer means for as long as neither stylus is in an operative position. Changeover is effected by rotating the stylus holder and, during rotation from one operative position to the other, an eccentric member secured to the stylus holder co-operates with a bearing surface to move the stylus holder out of contact with the transducer means. A stereophonic pickup comprises two piezo-electric transducer elements 3, 4 (Fig. 3) each clamped at one end (not shown) in a two-part housing 1, 2 (Fig. 1). A stylus holder 5 is provided, comprising a shank 6 carrying two styli 7, 8 and a bearing cap 9 (Fig. 2). Bearing cap 9 is of viscoelastic material and comprises a knob-shaped portion 10. Shank 6 is non-rotatably held in bearing cap 9 which in turn is non-rotatably carried by a drum 14 (Figs. 2, 4). Drum 14 is supported and guided by two U-shaped frames 22, 23. It has two flat faces 20, 21 and is constantly urged by a leaf spring 24 against the central portions of frames 22, 23. When one or other of the flat faces 20, 21 bears on the central portions of frames 22, 23 one of the styli 7, 8 is in its operative position and knob-shaped portion 10 bears against transducer elements 3, 4. If drum 14 is turned from such a position by movement of an operating rod 25, the cylindrical portion 19 of the drum 14 engages the central portions of frames 22, 23 to lift knob-shaped portion 10 clear of the transducer elements 3, 4 until the other stylus is in its operative position. In a second embodiment, a knob-shaped portion 33 (Fig. 8) is tilted clear of the transducer elements during change-over of the styli. Portion 33 is part of a bearing cap, the outer surface of which comprises parts 36, 37 each in the form of a segment of a sphere, a cylindrical part 39 and a frusto-conical part 38. The frusto-conical part 38 is flattened in two places (see e.g. 40) to provide flat surfaces. The bearing cap is supported and guided by two U- shaped frames 42, 43 having circular-sectioned faces 45, 46 &c. The central portion of frame 43 is engaged by a flat surface of frusto-conical part 38 in the operative position of a stylus so that portion 33 engages both transducer elements. During change-over from one stylus to the other, by movement of an operating rod 49, portion 33 is tilted clear of engagement with both transducer elements.

Title: Improvements in or relating to aerial-barrage projectiles and like anti-aircraft weapons
IPC: F42B10/56
Filed: 1939-10-21
Abstract: 540,284. Ammunition projectiles. IONIDES, A. G. Oct. 21, 1939, No. 28391. [Classes 9 (i) and 9 (ii)] Relates to aerial barrage projectiles of the kind in which the projectile A, Fig. 2, contains a bomb H connected to a parachute D by a length of impact wire E which is intended to entangle enemy aircraft and cause explosion of the bomb. According to the invention, the impact wire includes near the bomb a spring coil F of a small diameter to act as a shock absorber on being uncoiled and straightened out. Further, a controlling sleeve or drogue G is connected to the wire near the bomb and at the end of the wire remote from the parachute. The projectile case A, Fig. 1, contains a propellant charge B and a charge C for expelling the parachute D connected by the wire coil E, spring coil F and drogue G to the bomb H. The tail of the bomb is lightly connected to a suspending parachute J and to a further parachute K attached to the projectile case A. When the wire is impacted by enemy craft, the parachutes J and K are detached and the case A falls slowly to the ground, the wire E entangling the aircraft X as shown in Fig. 3 and the drag of the parachute D causing the bomb to move against the aircraft. The fuze of the bomb is armed by rotation of the bomb only after the wire has been impacted. The projectile may be fired from a mortar forming part of a land or ship's battery or from aircraft. In the latter case, a non-recoil type of mortar is used in which the gun barrel is projected in opposite direction to the projectile.

Abstract: 720,357. Pneumatic tyres. FIRESTONE TIRE & RUBBER CO. Nov. 14, 1952 [May 3, 1952], No. 28754/52. Class 144 (2) A tyre cover having a fabric carcase is provided with a separate superimposed rubbery non-staining black sidewall containing migratory waxy materials extending from the tread to the bead and a light-coloured (white) member is superimposed on and bonded to the black sidewall. Fig. 3 shows a carcase 43 with a black non-staining sidewall 40 which is formed with a circumferential rib intermediate the tread (not shown) and the bead. The sidewall 40 contains a migratory wax which retains a protective bloom on the surface of a white decorative rubber veneer or strip 44 bonded upon the wall 40 to extend from the rib to the bead. In manufacture the strip 44 overlaps the black sidewall rib, the overlap being buffed away to provide an even junction line between the black and white portions. The use of wax-impregnated non- staining black sidewall rubber allows the use of relatively thin white rubber strip. In a white-rib tyre, Fig. 4, the white rubber strip 23 is slightly thicker and formed with the desired rib, a junction strip 24 of black non-staining rubber being stitched over the outer edge of the white strip to overlap the rib for subsequent buffing away.

Title: Means for deriving a voltage dependent upon the mean voltage of a modulated carrier wave, for example for automatic gain control purposes
IPC: H03G3/22
Filed: 1939-10-26
Abstract: 533,275. Automatic volume control. HILL, C. J. W., and SMITH, J. W. Oct. 26, 1939, No. 28769. [Class 40 (v)] A circuit for deriving a voltage dependent upon the mean voltage of a modulated carrier wave comprises two rectifiers connected in opposition such that the modulation components cancel one another, the desired voltage being derived from only one of the rectifiers. The modulated carrier wave is applied through condensers Cl, C2 to the rectifiers D1, D2, which are connected in opposition and are provided with load resistances R1, R2 the outputs from which are combined through high resistances R3, R4 and an isolating condenser C3. In the circuit the audio-frequency components are cancelled out and, due to condenser C3, only the D.C. output from diode D2 is passed through a filter C4, C5, R5, R6 to remove radio frequencies and then to the grid of a D.C. amplifier T, from the anode of which the desired A.G.C. voltage is taken. A negative grid bias for the triode T is obtained from the resistance R9 and this serves as a delay voltage for the A.G.C.
