Title: Improvements in automatic record-changing mechanisms for gramophones
IPC: G11B17/16
Filed: 1948-02-20
Abstract: 642,790. Automatic gramophones. SKANDINAVISKA ODEON AKTIEBOLAGET. Feb. 20, 1948, No. 5133. Convention date, April 3, 1947. [A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 23, 1948.] [Class 40 (ii)] An automatic record changer of the type in which a pile of records is supported above the turntable on the shoulder of a central pin and on a swingable circumferential support, is characterized in that a single shaft serves to support a loading weight for steadying the records which is combined with a switch for stopping the gramophone after the playing of the last record. In Figs. 1 and 5, the records are supported on the shoulder of a central pin 4, and on a support 7 placed at the circumference. The support 7 is fixed to a sleeve 8 which engages a sleeve 13, by means of lugs 11, which is fixed to arm 14, the whole being assembled on shaft 9. After the playing of a record when the pick-up arm 26 reaches the run-off groove, arm 28, which is fixed to arm 26, engages stop 24, partially rotating disc 18 so that the recess at the edge of this disc opposite sleeve 20 is moved, and disc 18 is then driven one revolution by frictional engagement with sleeve 20 which is fixed to the rotating turntable 2. The raising and lowering of the pick-up arm is controlled by a cam (not shown) on disc 18 engaging a stop 25 which controls a lever arrangement (not shown). Stop 23 engages lever 33, which is pivoted at 34, and which by means of lever 31 moves the pick-up arm out to the position shown in Fig. 1. Stop 24 then engages lever 39 which by means of lever 37 rotates lever 14 and the support 7 about spindle 9 to restore them to the position shown in Fig. 1. Stop 22 then engages lever 14 and this rotates support 7 so that the record pile is supported on a different portion of support 7, but the bottom record is urged inwards by stop 43 during this movement so that it is released from shoulder 5 and support 7 and therefore drops on to turntable. Stop 21 then engages lever 14 and rotates this still further so that it contacts stop 35 on lever 31 to move the pick-up arm inwards ready for lowering on to the record.' When the last record has been played, weight B and arm b which are keyed to shaft 9, descend on to support 7 and are rotated by stop 44 when support 7 rotates due to the action of stop 24. The resulting rotation of shaft 9 is used to control a switch (not shown) to switch off the apparatus. When the apparatus is switched on, disc 18 immediately starts to rotate, causing stop 22 to engage lever 14, to commence the cycle of operations. To avoid record damage, stop 43 may be resiliently mounted on support 7 so that it may be pressed downwards by the record pile. When records of a smaller diameter are used, the support 7 and sleeve 8 assembly is disengaged from sleeve 13 and rotated .180 degrees. The other side of support 7 with corresponding stop members is then utilized to support the record pile, and lever 17 is used instead of lever 14 to control the pick-up movement via. stop 35.

Title: Transiently regenerative amplifier
IPC: H03F3/217
Filed: 1965-02-08
Abstract: 1,059,853. Bi-stable circuits. CARTER PRODUCTS Inc. Feb. 8, 1965 [March 3, 1964], No. 5447/65. Heading H3P. An amplifier comprises A.C. and D.C. positive feedback circuits which are periodically rendered effective so that the amplifier regeneratively responds to an input signal applied to its input, the arrangement being such that the D.C. feedback becomes effective after the A.C. feedback. The left-hand plate of an input capacitor 9 takes up the potential of an input signal applied at 6 and the left-hand plate of feed capacitor 12 is connected to ground through 22. Accordingly, when the chopper switch 20 is changed over the inputcircuit potential is moved towards zero and by regenerative action the amplifier output builds up to a limit corresponding to the direction of change. The initial-regeneration occurs through capacitors 12 and 9, the latter being so small that between chopping cycles low-frequency noise is blocked for the amplifier. As the output voltage builds up the potential across one of the diodes shunting each capacitor passes the knee in its forward characteristic and the diode becomes conductive to complete the D.C. feedback path. If contact bounce occurs when the switch moves to 21, diodes 23 and 24 maintain an A.C. feedback path through their selfcapacitance and maintain the D.C. feedback path when the voltage across them has built up a value sufficient to make them conduct. The output of the amplifier operates a relay 3 through a trigger circuit, the relay being maintained operated between chopping cycles by a freewheeling diode or by arranging for the trigger to have appreciable hysteresis. Two triggers may be provided to indicate respectively positive and negative signals. The D.C. feedback loop may alternatively be connected to the right-hand side of the condenser 9 (Fig. 4, not shown) or, when the amplifier comprises an A.C. stage followed by a D.C. stage, may be connected to the input of the D.C. stage (Fig 5 and 6, not shown).

Abstract: 139,512. Aktiebolaget Svenska Kullagerfabriken. Feb. 27, 1919, [Convention date]. Roller bearings.-In a roller bearing having a spherical race, the rollers and races have such form that the resultant of the forces on a roller tend to move it axially, this movement being prevented by a guide-flange formed on one of the race rings. Fig. 4 shows two rows of rollers which tend to move up against a guide-flange 4, which may have spherical or conical surface fitting against corresponding concave or convex surfaces on the ends of the rollers. The rollers are spaced by a cage consisting of two rings 6, 7 secured together back to back and formed with tongues 8, 9 separating the rollers. The rollers are so shaped that tangents at the points at which the resultants of the pressures on the races act intersect at or near the axis of the bearing. The longest or smallest diameter of a roller may be at one end of the roller. The rollers may have either line or point contact with either race. Fig. 5 shows a modification in which the inner race 3 is spherical and the rollers 2 have concave running surfaces. More than two rows of rollers may be employed. The bearing may have a row of rollers designed to take mainly axial thrust. The bearing may have such form that the rollers do not prevent the separation of the two race rings.

Class 20(ii) In a telescopic pit prop in which lock wedges 4, 5, 6, 7, Figs. 1, 2, are adapted to exert pressure on a drag wedge 8 to clamp the inner and outer prop parts 1, 2 together, the drag wedge 8 being adapted to be carried along by the part 1 until arrested by a stop 11 and a spring 12 operating to return the drag wedge to its initial position when clamping pressure is released, the arrangement is such that the wedge 8 is automatically given a component of movement away from the inner part 1 during the spring return of the wedge from its arrested position. The inner part 1, Fig. 1, is of trough section, having converging walls clamped between the drag wedge 8 and guide plates 9, 10 on the lock. The spring 12, Fig. 2, is mounted internally of the drag wedge on a pin 13 which at its lower end abuts on an inclined part 15 of the stop 11 so that in the spring urged return movement of the wedge 8, the pin 13 slides down the incline and the lower end of the wedge 8 moves away from the inner part 1 which is thus less restrained in sliding in the outer prop part 2.
