Abstract: 736,576. Magnetic recording and reproducing apparatus. MULLER, W. Nov. 3, 1953 [April 23, 1953], No. 30317/53. Class 40 (2). A magnetic sound record apparatus employing a broad endless sound carrier 57 has a single transport roller 5 which co-operates with a pressing-on device 65 in relation to which the sound head 30 is longitudinally movable by a leadscrew 14. The sound head 30 is mounted on a lever 19 pivotally supported at 20 on a carriage 18 slideable on a slotted tube 17 which almost entirely surrounds the leadscrew 14. A cruciform member 24 is pivoted at 28 on the carriage 18 and has an arm 25 which enters the slot in the tube 17 and engages the leadscrew 14 to effect traversing of the carriage 18. A spring 22 joins member 24 and level 19 and serves to hold the arm 25 of member 24 against the leadscrew, and the sound head against roller 5. The leadscrew is driven by means of gearing airanged between it and the roller 5, which in turn is driven by means of its fly-wheel 8 through a friction tiain from a motor shaft 39. The intermediate driving member 47 may be disengaged from the fly-wheel 8 by means of a squared shaft 54 which is rotated 45 degrees at eveiy operation of a push-rod 48, Fig. 6, so that successive operations interrupt and restore the drive to the roller 5. The transducer may be manually moved to any part of the roller 5 by downward pressure and then sideways movement of an indicator member 15 mounted at the top of a vertical slide 16 having a projection 16<SP>1</SP> which engages a pin 29 on the member 24 when the member 15 is pressed, whereby the arm 25 is disengaged from the leadsciew 14. Fine adjustment of the leadscrew and transducer relative to the roller 5 is effected by means of a hand level 36 which has an inclined surface 35 which bears on the end of the leadscrew 14 and moves it endwise against a leaf spring 34. The pressing-on device 65 holding the carrier 57 against the roller 5 is of soft indiarubber and is affixed to the end 72 of a guide plate 58. A slantmounted roller 64 is provided to ensure that the record carrier is made to register against the flange 7 on the roller 5. When the apparatus is in the operative position a sector-shaped arm 60 blocks the entrance between the roller 5 and guide wall 58. The square shaft 61a on which the arm 60 is mounted carries a bar 62 which serves to hold the sound-head 30 out of contact with the roller 5 when arm 60 is moved away from the end of the roller 5 while sound carriers are being changed.

Filed: 1926-12-02
Abstract: 263,120. New Jersey Zinc Co., (Assignees of Hooey, W. C.). Dec. 15, 1925, [Convention date]. Pigments. - In the manufacture of lithopone the physical properties thereof are controlled by establishing a predetermined ratio between and/ or excess of, the hydrate and sulphydrate radicals present in the crude pulp at the endpoint of the reaction between the zinc sulphate and barium sulphide solutions. The chief physical properties affected are oil-absorption, alkalinity, covering power, light-resistance and metability. The effects on the physical properties of varying amounts of hydrate and/or sulphydrate in the crude pulp are determined, and the precipitating step is then controlled by means such as are described in Specification 263,119, to obtain that excess and/or ratio of the radicals as will give the required properties. The excess and/or ratio of the radicals may be so controlled as to permit of the calcination being effected at a lower temperature than will materially affect the lightresistance of the lithopone, but will give it the desired covering power. Specifications 188,311, 189,523 and 189,525 also are referred to.

Abstract: 832,725. Reverse gear control. ALLISCHALMERS MANUFACTURING CO. Sept. 30, 1957 [Oct. 10, 1956], No. 30588/57. Class 80 (2). [Also in Group XXXI] The forward and reverse gearing for a selfpropelled earth working vehicle is controlled by a lever moving a slidable clutch member through means which, when the clutch is in the engaged position, transmit a substantial proportion of the clutch back-thrust to the support housing. A motor grader has a main frame 11, a motor 12 and an operator station 13 between the front steerable wheels 14 and the rear traction wheels 16. A power take-off 24 on the engine 12 is connected by jointed shafts 26, 27 to suitable change-speed gearing 28 and thence to the input shaft 31 of a power control device 30 having a plurality of control stations 33 which can cause torque to be transmitted through jointed shafts 34, 35, 36 to the corresponding adjustable mechanisms 37, 38, 39. Forward rotational drive from the input shaft 31 to the plurality of output shafts 57 is provided by a train of gears 46, 52, 54, 59 driving a dog clutch member 68 freely rotatable on the shaft 57. Reverse rotation is transmitted by a pair of gears 46, 52, 76, 58 to a second dog clutch member 72 also free on the shaft 57. The shafts 57 are driven by the gears 58, 59 selectively by dog clutch sliding members 67 splined to the shafts 57 and actuated by forked members 82 sliding on rods 79 in the housing 33. Each fork member 82 is actuated by a lever 32 attached to a crank-arm 96 secured to one end 92 of a transverse pivot 88, the arm 96 being urged to a central neutral position by a pair of spring-loaded plungers 134, 136. The pivot 88 carries a link member 102 having arms 103, 104 carrying pins 120 which engage slots 111 in two pairs of links 107, pivoted on the forked member 82 at 86. The arrangement of the linkwork between the pivot 88 and the member 82 is such that it forms a toggle which provides actuation for the clutch sliding member and, in the engaged position, transmits substantial thrust produced by the inclined faces of the dog clutch directly to the housing 33 and leaves only slight thrust in the lever 32 for feel. Adjustable stops 121, 122 limit the movement of the linkwork to provide the desired amount of feel. In a modification the arms of the member 102 carry rollers which cam against upstanding parts of the fork member 82, to provide a substantially locking linkwork.
