Abstract: 888,934. Folding and stacking material. KAUSCHKA, R. Aug. 6, 1958 [Aug. 7, 1957], No. 25235/58. Class 42 (2). A web of foldable material 13 is formed into a stack 23, from the top of which it can be withdrawn, by supplying it in folds to the bottom of the stack. The web is guided to the stack between two parallel rollers 4, 5 mounted on an arm 3 for reciprocating movement along a curved path and geared together by a chain drive 6 to rotate in the same direction. The web passes between bars 11, 12 mounted on levers 14, 15 carrying rollers 18, 19. In one end position of the reciprocating movement, roller 18 engages a cam-like abutment 20 to swing bar 12 to the Fig. 2 position in which it pushes the material in a fold between the stack 23 and roller 4. Similarly engagement between roller 19 and an abutment 21 forms a fold at the other end of the movement. The stack is supported on straps 7, 8 adjustably secured at one end to members 9, 10 and wound at the other end around rollers 4, 5; the length of the straps is such that they form approximately a circular arc to which the surfaces of rollers 4, 5 are tangential during their movement.

Title: Improvements in or relating to light spot scanning arrangements for picture transmiss
Inventor: THEILE RICHARD
IPC: H04N5/202
Filed: 1950-10-17
Abstract: 695,974. Television. PYE, Ltd. Oct. 15, 1951 [Oct. 17, 1950], No. 25269/50. Class 40 (iii). In a picture-transmitting arrangement, particularly a television transmitter, wherein the transparency or other object to be transmitted is scanned by the image of an unmodulated scanning spot on the screen of a cathode-ray tube, and the light transmitted by or reflected from the object excites a photo-electric cell to develop a picture signal, a portion of the signal derived from the photo-cell output is fed back negatively, via a variable manual control, to the cathode-ray tube to control the intensity of the scanning spot in such a manner as to improve the " gamma " of the picture reproduced from the developed signals, and a gain control is ganged with the feed-back control so as to keep the peak amplitude of the signals independent of the feed-back. In the arrangement shown, the image of a scanning raster traced on the screen of the.cathode-ray tube 1 scans the transparency 6, light passing through the transparency falling on the photo-cell 8 and generating a signal which is amplified at 9, 10 and 11. A signal taken from the cathode circuit of the stage 11 is fed back to the control grid of the cathode-ray tube 1 via amplifier 19 and D.C. restoring circuit 18. In this way the signal developed may be made to bear a non- linear relationship to the intensity of the transparency and, by a suitable choice of the amount of the feed-back, thus compensate for a corresponding non-linearity in conventional cathoderay tube receivers. The output signal is taken from the anode of stage 15, the feed-back control is ganged with a gain control in such a fashion that the peak amplitude of the output signal is made independent of the feed-back. In an alternative arrangement, Fig. 2 (not shown), the amplifier stages including the gain control are arranged so as to be not within the feed-back loop. In the scanning of a continuously moving kinema film the spot on the cathode-ray tube screen scans a single horizontal line only. It is stated that the use of negative feed-back also compensates for effects due to the afterglow decay time of the screen of the tube 1. However more negative feed-back is required for this compensation than for the " gamma " control; accordingly the condensers 12 and 13 are provided to obtain a suitable amplitudefrequency characteristic in the feed-back system to provide additional compensation for the afterglow effects.
Patent GB-480023-A (GB)
Title: Improvements in or relating to magazine gramophones and the like
IPC: G11B17/02
Filed: 1936-09-16
Abstract: 480,023. Magazine gramophones. LOWE, A. E. BOWYER-. Sept. 16, 1936, No. 25274. [Class 40 (ii)] The unplayed records are supported on a table 16 and are transferred successively to the turntable by the horizontal movements of a pivoted feed-arm 41 after the table has been raised to effect disengagement of a spindle 1 from the central hole of the uppermost record. The vertical movement of the table causes the uppermost record to lift a feed pin 43, carried by an arm 42 attached to the feedarm 41, from the end of the spindle 1 to open the circuit of a driving motor 33, the momentum of the moving parts being such that when motion ceases the undersurface of the topmost record is clear of the end of the spindle 1. The latter is secured to, but insulated from, a screwed member 2 placed within a sleeve 7 on which the table 16 rests, and one end 10 of a crank lever 12, pivoted at 11 to said sleeve, engages with the thread formed on the member 2, whereby the table is raised as a result of rotation of the threaded member. By withdrawing the lever 12 from engagement with the thread, the vertical position of the table may be adjusted. The screwed member 2 is driven by the motor 33 through a belt 35 and gear wheels 31, 26, 21 and 4. A boss 22 of the pinion 21 is provided with two helical springs 23, 30, one end of the former being attached a fixed stop 24, and one end of the latter to the pinion 26, their other ends being free, such that the pinion 21 is rotated only when the pinion 26 rotates in a clockwise direction, to raise the table 16. When a record is to be transferred to the turntable, the feed-arm 41 is rotated from a neutral position intermediate the turntable and magazine, as described in Specification 480,024, until the record-engaging pin 43 is vertically above the spindle 1, when the feedarm is lowered to bring the pin 43 into engagement with the end of the spindle 1 to close the circuit of the motor 33, the rotation of which raises the table 16 and records until the topmost record lifts the pin 43 out of contact with the spindle 1 to open the circuit of the motor.

Abstract: 699,324. Recording apparatus. HELL, R. Oct. 30, 1951 [June 22, 1949], No. 25357/51. Class 106 (iv). [Also in Group XL (b)] Recording apparatus wherein signals to be recorded are represented by movement of a stylus member in a direction transverse to the direction of movement of the recording tape comprises tape-guiding means causing the tape to extend freely at a slight distance from a backing roller whose axis is transverse to the length of the tape and whose profile forms with the tape a narrow gap throughout the line of stylus movement across the tape, the stylus member being arranged to deflect the tape into contact with the backing roller at. a point movable along the said line according to the movement of the stylus member and an inking device for continuously inking the backing roller during movement. A roller 12 driven by a motor 13 and coacting with a roller 14 draws a record tape 1 through a braking device 19 under rollers 10, 11 and over guides 8, 9 which slightly space the tape from a backing roller 5, except at the recording point, where a stylus 3 presses the tape 1 into contact with the roller 5, thus reducing friction to a minimum. The roller 5 is also driven by the motor 13 and it is continuously inked by a roller 6, though a transfer roller may be interposed. The stylus 3 has a hard and sharp point, e.g. a jewel point, and is traversed over the tape by movement of a shaft 3<SP>1</SP> of an instrument 4, the shaft 3<SP>1</SP> being journalled in ball bearings at the top and its lower end forming a torsional pin fixedly mounted in the instrument frame. The speed of the motor 13 is controlled by a centrifugal device with a flyweight 15 counteracting against a spring 17 whose tension may be manually adjusted through a cam 18. Alternative forms of stylus are described including a cylinder with a helical ridge, a disc with. a sharp edge mounted obliquely on a shaft and a disc journalled between two springs parallel to the length of the tape across which they are caused to oscillate by a solenoid. The solenoid may be duplicated on the opposite side of the stylus member to double the actuating force, while any suitable kinematic means may be interposed between the actuating means and stylus means for amplifying the stylus movement and/or causing the movement to conform to a desired geometric function of the movement of the actuating means. The invention is applicable to recording the indications of measuring instruments and to telegraphic recordirig, particularly to printing Morse.
