Title: Improvements in or relating to devices for recording sound oscillations in spiral grooves on planar carrier
IPC: G11B3/00
Filed: 1954-03-22
Abstract: 746,551. Recording sound. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 22, 1954 [March 25, 1953], No. 8292/54. Class 40(2) In a disc-recording apparatus the groove spacing is varied in accordance with a control voltage varying with the amplitude of the sound oscillations being recorded, characterized by circuit elements providing limitation of the control range for both comparatively small and comparatively large amplitudes. In the embodiment described, the sound signals to be recorded are taken from a magnetic tape 1 by means of a head 4 and amplifier 5, while the control signal is taken by a head 2 from an earlier part of the tape at a point corresponding approximately to the time period of one revolution of the disc record. The output of the head 2 is fed to a limiting circuit 3 which produces a varying voltage controlling the speed of the driving mechanism effecting the traverse of a cutting head across the record disc. The limiting circuit (Fig. 4) comprises a transformer 6 and a rectifier 7 which demodulates the control signal to produce a D.C. voltage across a resistor R1 the threshold valve at which rectification takes place being adjusted by means of a variable D.C. voltage source 8. An output voltage appears at terminals 10 across a resistor R2 which forms with resistor R1 a potentiometer across resistor R. A condenser C2 across R2 produces a suitable time delayed build up of the control voltage, while a rectifier 11 and adjustable D.C. source 12 limits the maximum value of the control voltage. The control voltage may be utilized to affect the internal resistances of negatively biased tubes constituting the resistors in an RC filter determining the frequency of an oscillator feeding a synchronous motor controlling the traverse of the recording head.

Title: Method of making hollow metal bars
IPC: B21C37/06
Filed: 1928-03-19
Abstract: 296,644. Wheelwright. T. S. March 19. 1928. Tubes; cased forms.-In making hollow steel cr other metal bars, particularly hollow stay bolts, an ingot is formed by casting metal round a hollow metal core containing refractory material and surrounded by a parallel jacket of metal rods, and the composite ingot is then heated to rolling or drawing temperature and after rolling or drawing the refractory material is removed. The core consists of a tube 25, Fig. 5, filled with silica sand and closed by a plug 26, or filled with a mixture of silica sand, linseed oil and sawdust by ramming round a vent rod, removing the rod and then baking the composition core. One or two rows of wrought iron or steel rods 27 are secured by bands 28 round the tube, and the core so formed is placed in a mould and steel run thereinto to fuse the rods and complete the ingot. The moulds consist of a series of sections 2, 3, 4 &c. with mould cavities on each side, each mould being formed by two adjacent sections. The sections are secured together by bars tightened by wedges. Each mould has a hot top 8, formed of a mixture of silica sand, linseed oil and sawdust and provided with a basin 15, gates 19 and a recess 20 to receive the upper end of the core, the recess communicating with the atmosphere through a port 24. The hot tops communicate with each other through gates 12 and the gates 19 are spaced round the mould so that the molten metal is prevented from striking the tubular part of the core so as to avoid buckling thereof. The lower end of the core is received in venting grooves in the base of the mould. After coating, the ingot is removed, the refractory material removed and replaced by silica sand. The. ingot is then reheated and is passed first through a series of polygonal passes, e.g. hexagonal. octagonal, or gothic, in a pair of rolls and finally through a circular pass. The bar is then rotated in a lathe and the refractory material removed bv a jet of compressed air forced through a tube inserted in the bore. Specification 280,382 is referred to.

Abstract: 740,037. Measuring fluid flow. GENERAL ELECTRIC CO. March 22, 1954 [March 24, 1953], No. 8340/54. Class 40(1) [Also in Group XXVI]. In a rotary fluid meter the fluid in being accelerated radially out through .an impeller causes the impeller to experience a torque which is evidenced as a small angular deflection of the impeller from its mean position; this deflection being proportional to the mass of fluid flowing per unit time is translated into and measured as a variation in an A.C. bridge circuit. The ends of the arms 7 of the impeller have magnetic material members 23, 24 which move between coils 32, 29, 30, 31 with cores 26, 25, 28, 27 respectively. The coils 30, 29 are connected in one arm and the coils 31, 32 in another arm of the A.C. bridge as in Fig. 3 where the remaining two arms and an indicating in. strument such as a galvanometer are rep resented by 37. A deflection of the impeller arms 7 causes the impedences of the two arms containing the coils 29, 30, 31, 32 to be varied in opposite senses causing a differential effect. When the direction of flow of the fluid is reversed the deflections are in the opposite sense. In a modification (Fig. 4, not shown), a permanent magnet rotor is deflected inside an annular core having a polyphase tapped winding which is connected to a like wind ing on a similarly constructed repeater unit, the rotor of which actuates a pointer.
