Title: Improvements in or relating to magnetic sound recording and reproducing apparatus
Inventor: DUTTON GILBERT FARADAY
IPC: G11B21/04
Filed: 1951-05-31
Abstract: 704,175. Magnetic recording and reproducing apparatus. ELECTRIC & MUSICAL INDUSTRIES, Ltd. May 28, 1952 [May 31, 1951], No. 12807/51. Class 40 (2). In a magnetic recording and reproducing apparatus for disc shaped records in which a transducer supporting arm 5 is made to traverse the record 3 by means of a central tracking disc 4, the said arm 5 is mounted for movement about two mutually perpendicular axes 6, 9 whereby said arm 5 can be moved in planes respectively parallel and perpendicular to the plane of the turntable, the transducer 5 and/or the means engaging the tracking disc 4 being mounted for movement relative to the said arm so as to enable proper engagement of the transducer to be made with the record, and the tracking disc with the engaging means on the said arm. In the embodiment described and illustrated, the transducer 15 is secured to a U-shaped bracket 21 pivoted on a fixed axis 22 in a part 14 of the casing of the arm 5 so that the transducer rests by gravity on the record. The means for engaging the tracking disc consists of a toothed wheel 16 the teeth of which engage the grooves of the tracking disc. The wheel 16 is normally fixed and stationary and is associated with a solenoid 23'by which means the wheel can be rotated step by step for backspacing and similar purposes. This feature of the apparatus forms the subject of Specification 649,260. In the present Specification, this part of the apparatus is mounted for limited movement in the part 14 of the arm 5 for the purpose of obtaining a fine adjustment of the tracking means relative to the transducer. The adjustment is effected by a lever 28 movable about a fixed point 26 and controlled by a cam rotated by a knob 29. Pressure on the tracking disc is reduced by means of a counterbalance spring 11. Instead of the transducer being movable about the axis 22, the tracking wheel and solenoid may be mounted to pivot about a similar axis in the region immediately above the transducer 15, said axis being in a movable bracket whereby fine adjustment of the relative positions of the transducer and tracking means may be affected. If desired, the transducer and the toothed wheel may be mounted at opposite ends of a pivotally mounted carrier. Specification 697,161 also is referred to.

Abstract: 528,200. Current and voltage measurements ; compensating instruments for temperature errors. SANGAMO WESTON, Ltd. April 28, 1939, No. 12836. Convention date, Aug. 31, 1938. [Class 37] [Also in Group XIII] In a thermal instrument in which oppositely wound bimetal strips 13, 14 act differentially on a shaft 10 carrying a pointer 11, the strip 13 being heated by a resistance 19 carrying the current to be measured, the bimetal strips have non-linear temperature-defection characteristics so as to compensate for changes in ambient temperature. The bimetal strips may consist of a layer of brass in combination with a layer of alloy comprising about 40 per cent. of nickel, 0.2 per cent. of carbon, and the remainder iron. Such strips are stated to have an increasing temperature-deflection ratio with rising temperature which may be employed for inherently compensating for changes in ambient temperature. The brass component of the bimetal strips may be replaced by chromevanadium steel.

Patent GB-636386-A (GB)
Title: Remote control apparatus for an actuator
IPC: G05D3/12
Filed: 1946-04-30
Abstract: 636,386. Controlling aircraft. MILES AIRCRAFT, Ltd., and HUNT, C. L. April ' 30, 1946, No. 13004. [Class 4] [Also in Group XXXVIII] In a remote control system, whereby an actuator employed in an aircraft for adjusting control surfaces (or for providing power for other operations) may be controlled by the pilot or an automatic pilot so as to follow the movements imparted by the pilot or the like to control means, rotation of the stator of a resultant field type motor causes the rotor to attempt to follow, thus completing circuits to drive an actuator in the direction of rotation of the stator. Simultaneously the actuator drives a transmitter to rotate the stator field until the rotor breaks the contacts supplying the actuator. Alternatively the contacts may be turned carrying the rotor with them. The system as described with reference to Figs. 1 and 3 incorporates an anti-hunting arrangement. Movement of a knob 9 causes a spring-loaded contact 14 to engage with one of contacts 16a or 16b and then rotates the stator. If contacts 14, 16a close, the rotor turns to close contacts 12, 13a, thereby energizing a relay 17a which short-circuits contacts 14, 16a and supplies the actuator 7. The actuator drives diametrally opposite supply contacts of a ring potentiometer 5 having three equispaced points from which the stator of the resultant field device is fed. The resultant field of this stator rotates until contacts 12, 13a part. Should the motor overrun no reverse circuit is established since contact 14 is not made with contacts 16a or 16b. Specifications 627,004, 627,005 and 636,171 [all in Group XXX], are referred to.

Filed: 1930-04-28
Abstract: 347,879. Sintering apparatus. GREENAWALT, J. E., 110, East 42nd Street, New York, U.S.A. April 28, 1930, No. 13056. [Class 82 (i).] Sintering machines more particularly of the intermittent type comprise the combination with a rotatable sintering pan P, of a sinter receiving hopper 6, means for sealing the adjacent edges of the pan and the hopper from atmospheric air, said means comprising hinged gates 29 at the ends of the hopper adapted to rest on the ends of the pan, and means for causing a blast of air to traverse the hopper. The sintering pan P is rotatably mounted on beams 1 with its upper edge on the level of the charging floor F on which operate an ignition hood 3 and a charging car 2 fed from a screen 5. The upper edge of the hopper 6 is connected with the beams 1 and with members 7, 27 spaced from the sides of the pan to provide clearance for rotation. The bottom of the hopper is closed by a crusher 8 which feeds the sinter on to a screen 9. The pan P is connected by way of a hollow trunnion 13, pipe 14 and dust collector 15 to the intake of the sintering fan 17 which discharges into an outlet stack. When the material has been treated for a sufficient time the pan P is inverted, and the sinter discharged into the hopper 6. At this time the fan 17 is idle and a second fan 20, connected through a dust collector 22 to a main pipe 24 and branch pipes 25, draws through the hopper a blast of air which serves for removing dust and cooling the hot sinter. The spaces between the upper extension of the hopper and the sides of the pan at right-angles to the axis of rotation are closed by plates 29, Fig. 5, hinged at 28 at about floor level and resting on the edge f of the pan. When the pan is rotated the plates are lifted and held up by the upper edge of the driving gear 30. The spaces at the other sides of the pan are sealed by means of wipers 32, Fig. 6, contacting with arcuate plates 31 fixed to the members 7.
