Abstract: 1338103 Weight compensating WERKZEUGMAOHINENFABRIK ADOLF WALDRICH COBURG 19 April 1971 [6 Feb 1970] 21109/71 Heading B3B  In a portal or cantilever type machine tool having a vertically movable cross rail 2 and a horizontally movable tool head 1, the weight of the tool head 1 is counter balanced by a cable 3 which leads to a cable winch 5 mounted on a carriage 8 which is movable in synchronism with the tool head 1 along rails 11, 14, the winch 5 being mounted resiliently on the carriage 8 by means of a spring biased slide movable in the direction of the cable, and a feeler and a regulator control the power supply to the winch motor 7b, e.g. hydraulic supply to an hydraulic motor, to produce a constant pull on the cable 3 despite vertical adjustment of the cross rail 2. A further feeler mounted on the carriage 8 engages the cable and detects angular deflection from a vertical position of the cable so that as the tool head 1 moves along the cross rail 2 the carriage 8 moves in synchronizm therewith. The further feeler controls a regulator for a further hydraulic motor that drives a pinion in engagement with a rack attached to the crosshead 22, or an auxiliary girder 13, to move the carriage 8. To prevent bending distortion being passed to the crosshead 22 and columns 21, the rail 11 is mounted on an auxiliary girder 13 mounted by free fulcrums at each end. The cable pull is set greater than the weight of the tool head 1 to pull the head up against the guides that will take load during a cutting operation.

Title: Improvements in record-changing apparatus for phonographs
IPC: G11B3/095
Filed: 1956-07-09
Abstract: 793,502. Automatic gramophones. TESLA RADIO CORPORATION OF SOUTH AFRICA (PROPRIETARY), Ltd. - July 9, 1956 [July 10, 1955; July 26, 1955], No. 21225/56. Class 40 (2). An automatic record player is provided with preset means to select any playing position, or any one of a number of positions, from the centre of the turntable. The first embodiment is described comprising a modification of the apparatus in Specification 693,594 in which the correct setting down starting position for the pick-up at the start of one of three different sizes of records is automatically effected by a stopmember set in accordance with the size of the particular record falling to the turntable. Such a stop-member, as illustrated in Figs. 2 and 7 of the present Specification, remains in its initial position if a record of smallest size falls to the turntable, or is tripped to one of two other vertical positions by the engagement of said records with a trip-lever 25 if the record of the larger two sizes falls to the turntable. The different vertical positions of stop-member 38 cause a stepped abutment 29 thereon to arrest a similarly stepped sector arm 30 on the pick-up arm spindle 33 on the inward traverse of the pick-up over the edge of the record. By means of the present invention the stop-member 38 is drawn below the path of sector arm 30 so that the pick-up arm may continue to traverse inwardly until the said sector arm is arrested by an adjustable stop-member 58 preset in accordance with a desired setting down position on the record. The lowering of the stop-member 38 to render it ineffective is accomplished by the manual operation of clutch knob 26 which, through a linkage 50, Fig. 2, shaft 52, forked arm 66 on a pin 67 on the member 38, Figs. 2 and 5, causes the said member 38 to be drawn downwardly against the tension of spring 40, Fig. 7. At the same time, the adjustable stop-member 58, Fig. 5, is lifted into the path of the sector arm 30 by a member 62 linked to shaft 52 by a bell-crank and a linkage 60, 61. The presetting of the adjustable stop-member 58 is effected through a linkage 95, 56, 55 and a toothed sector 54 by means of a graduated control 27, Fig. 1. A second embodiment is described wherein a known make of record changer, having a feeler arm which tests the size of the next record to be played in order to determine the normal setting down position, is modified in accordance with the aforementioned methods of the invention.
