Title: Record changer
IPC: G11B17/02
Filed: 1973-10-24
Abstract: 1452953 Record changer PIONEER ELECTRONIC CORP 24 Oct 1973 [25 Oct 1972] 49635/73 Heading G5R In an automatic record changer having a turntable centre spindle 84 with upper record supporting claws 95 actuated from closed to open position by downward movement of a control shaft 85 in the spindle and lower record supporting claws 87 actuated from open to closed position by rotational movement of the shaft, a motor driven control cam disc 10 is formed with first and second cam surfaces which co-operate with cam follower arms 75, 80 to control the spindle shaft movement and with a crank member 11 which co-operates with lever 13 and rotating plate 40 to control pick up arm movement. On actuating a reproduction start button the turntable motor and the cam disc motor are energized whereby roller 81 of cam follower 80 moves from high portion I 1  of cam 10l to low portion I 2  thus spindle shaft 85 is lowered under the weight of its record stack moving upper claws 95 outwards to support all but the lowermost record of the stack. As pin 74 of cam follower 75 moves into groove L2 the follower is rotated around shaft 71 and planer spring 76 at the other end of the follower engages pin 108 of the spindle rotating plate 107 thereby rotating the spindle so that the lower claws retract and the lowermost records falls to the turntable. The cam follower 75 is now rotated in the opposite direction as its pin moves along groove L3 so that the lower claws are reopened and as roller 81 of follower 80 now moves on to a higher part I 3  of cam 10l the spindle shaft 85 is moved upwardly so that the upper claws retract and the record stack is again supported by the lower claws. After the record has been dropped crank 11 and lever 13 drive plate 40 such that a pin 21 secured to the pick up arm is engaged between a moving lever 43 frictionally coupled to plate 40 and a holding lever 38 and the pin and hence the pick up arm are rotated until the end of lever 43 engages a projection 32a of a lever 32 set in dependence on the size of the record to be played. The projection 40c of the drive plate then moves the holding lever 38 out of engagement with pin 21 and the plate now rotates further so that cam portion 40b of the plate is below shaft 51 of the arm lifter so that the tone arm descends to play the record. The cam disc stops after 180 degree drive until lever 19 also coupled to the pick up arm co-operates with a further lever (not shown) to detect the end of record play. When this occurs the cam disc motor is re-energized to drive the disc back to its initial position during which the tone arm 9 is lifted and returned to its rest.  A last record detector is provided which operates on the absence of depression on spindle control shaft 85 when the last record has been released and facilities are provided for manual and repeat operation. Reference has been directed by the Comptroller to Specification 1,377,378.

Abstract: 1445009 Balancing inertia forces MINSTER MACHINE CO 26 Oct 1973 [21 Nov 1972] 50086/73 Heading F2X  A mechanical press has a slide which is driven in reciprocation by at least one crank-shaft mounted in the press frame in which the slide is guided, and driven in rotation, each crank-shaft having at least one throw connected to the slide by a connecting rod so that as the crankshaft rotates the press slide reciprocates, counterweights comprising rotatable eccentric masses being provided which dynamically balance the inertia forces which arise when the slide is driven in reciprocation, particularly at high speed. In the embodiment shown in Fig. 1, a pair of shafts 34, 40 are journalled in the press frame 14 in a plane perpendicular to the direction of reciprocation of the press slide 10, which shafts carry eccentric masses 50, 52 and are driven by meshing gears 36, 38, one of which (36) carries a cog pulley 32. A corresponding cog pulley 28 is mounted on the adjacent end of the crank-shaft 16 and a cog belt 30 provides the driving connection between these two pulleys 28, 32. The crank-shaft is driven from its opposite end by a clutch-brake 22, a drive motor 24 and a drive belt 26. The crank-shaft 16 has throws 18 each connected by a rod 20 with the slide 10. The centres of gravity of the eccentric masses 50, 52 are so positioned that when the throws 18 are in the downward position, the masses 50, 52 are in the upward position, and vice versa. A pair of eccentric masses 46, 48 is provided on the crank-shaft 16 to correct the imbalance of the crank-shaft itself and of the connecting rods 20. In an alternative arrangement (Fig. 2, not shown), the balancer shafts are gear driven from the press crank-shaft and thus rotate both in the same direction but opposite to the crank-shaft. All three shafts lie in the same plane and are parallel to one another, the plane being perpendicular to the direction of travel of the slide.

Title: Improved process for the electrodeposition of metals, alloys or compounds thereof from molten electrolytes
IPC: C25D3/66
Filed: 1965-12-02
Abstract: 1,134,217. Electrolytic deposition process using a molten electrolyte. UNION CARBIDE CORP. Dec.2, 1965 [Dec.14, 1964], No.51108/65. Heading C7B. While electrolytically depositing metals, alloys or compounds thereof on a solid cathode using a molten electrolyte, gas above and around the electrolyte surface is heated at least to the liquidus temperature of the electrolyte by heating means separate from the electrolyte heating means. Thereby, temperature differentials within the electrolyte which would normally cause circulation of the electrolyte are minimized and dense, fine grain deposits free from roughness are deposited. Fig. 1 shows resistance heaters 11, 13, a heat shield 12 and thermal insulation 10. Materials which may be deposited are Zr, Hf, V, Nb, Ta, Cr, Mo, W or alloys or compounds thereof, e.g. ZrB 2 . The electrolyte may be an all fluoride melt, other anions being present only as minor impurities. The melt may be composed of a base melt (a) comprising at least one fluoride of K, Rb or Cs and at least one fluoride of other elements higher in the electro-motive series than the metal to be deposited and (b) at least one fluoride of the metal to be deposited. The base melt may be a eutectic composition of LiF, NaF and Kf. The metal fluoride employed may be simple or complex. The electro-deposition is carried out in an inert, non- oxidizing atmosphere such as A, Ne, He, e.g. above or below atmospheric pressure. The cathode may be of stainless steel, graphite, Ni or Cu and may be pre-treated by anodizing. The source of metal to be deposited may be the anode or the electrolyte. Where the anode is the source it may be in the form of rods, plates, rondels or chunks or may be of particulate material in an Ni mesh container. The process may be an electro-winning, electro-refining, electro-plating or electro-forming process. An insoluble, soluble or gaseous anode may be used. Using an insoluble anode, e.g. of graphite, the voltage applied is at least as high as the breakdown potential of the melt but using other anodes, e.g. a gaseous H 2  anode or a soluble anode containing an active metal of Li, Na, K, Mg, Ca or Al the voltage need not be as high. Using an active metal anode the melt may be recirculated through an external station where active metal fluoride formed at the anode is removed and refractory metal fluoride added. Electro-forming may be on an Ni base which is subsequently dissolved in HNO 3  or mechanically removed, on a graphite base which is mechanically removed or on an alloy base which subsequently can be pulled away from the metal. The examples are of plating on to Cu rod: - I Ta, II Nb and III W. Specification 1,007, 930 is referred to.
