Abstract: 1,146,724. Decarburizing steel sheet. LEE WILSON ENG. CO. Inc. Aug.30, 1966 [Feb. 7, 1966], No.38607/66. Heading C7D. Steel for nitreous enamelling is produced from sheet having an initial carbon content of not less than 0À2% by heating it to the minimum temperature at which the structure is substantially all gammaphase, and while maintaining it at that temperature subjecting it to a decarburizing atmosphere until outer zones of alpha-phase having a carbon content of not more than 0À006% are produced, these zones each extending inwardly for 25% to 37% of the sheet thickness. The sheet is then cold-rolled and subcritically annealed. As exemplified a 8% hydrogen - 92% nitrogen atmosphere was used for heating and for annealing, water vapour being introduced during the decarburizing step to give a dew-point of 80 to 85F.

Abstract: 1,029,075. Automatic gramophones. FOSTER-MULLARD Ltd. Jan. 11, 1965 [Oct. 10, 1963], No. 39978/63. Heading G5R. A gramophone of the type described in Specifications 909,858 and 909,860 is provided with a switch 72 controlling an electric motor and spring biased to the " on " position, the switch being urged into the " off" position by a collapsible thrust member comprising a lever 75 and a trigger member 78, the thrust member being adapted to transmit movement to the switch button 73 from a lever 36 which acts to swing the pick-up arm during a control cycle; operation of a start control 92 collapses the thrust member which remains in this state until the stop control is operated or until there are no records left in the stack above the turntable. Fig. 2 shows the apparatus in the off condition. When the start control 92 is operated it exerts a thrust on rod 86, and a trip member 81 on lever 75 operates the trigger 78 to collapse the thrust member which is held collapsed by a latch lever 84. The collapse of the thrust member allows member 69, to which lever 75 is pivoted, to rock under the influence of spring 93; a dependent arm 67 of member 69 then causes one of the friction rollers 19 or 21 to engage the turntable and drive it from the motor (not shown) which was switched on by switch 72. Return movement of rod 86 after operation of the start control causes the interrupted gear 27 to be driven, thereby initiating a control cycle. When the control 92 is moved to the stop position a pull is applied to rod 86 thereby re-setting the thrust member, and a resilient arm 115 on the rod initiates a control cycle. A control knob 119 when moved to the " reject " position initiates a control cycle and when moved to the " repeat " position disables that part of the control mechanism which changes a record and reverses the direction of drive of the turntable. The record changing mechanism may be of the type wherein a forked arm 103 (Figs. 4 and 7, not shown) bears on a rod slidable in a record-changing to operate a release finger; if there are no records on the spindle the release finger is not restrained and the arm 103 moves more than usual thereby actuating a lever 108 which releases the latch 84 and allows the thrust member to re-set. At the end of a record the run-in of the pick-up arm operates a rod 11 which initiates a control cycle, and when the lever 75 is moved by lever 36 to open the switch 72 a rod 118 transmits the movement to swing the pick-up arm clear of the records. The direction of drive is reversed after each record, as in Specification 909,860, in order to play both sides of the record, and a brake 135 is applied by the drive reversal means at the moment of reversal.
