Abstract: 923,433. Eye fastenings; fastener tapes sewing-machines. STEEL & BUSKS Ltd. Nov. 27, 1959, No. 40303/59. Classes 43, 112 and 141. [Also in Group XXII] In a method of manufacturing eye-tape, eyes are laid at successive intervals on a base layer, are partially covered by an overlying layer, are secured in position by at least one line of stitching passing through both layers of the tape material and over limbs of the eyes, and subsequently have their uncovered ends bent upwards about a line adjacent to or substantially coincident with the stitching line. A machine sews along the edge of the folded layer 11 and opposite an eye 20 fed into position on a layer 10; a cam operates to oscillate the needle and sew each loop in turn. The folded part of the tape passes between two superimposed anvils 16, 17, and a plunger 21 reciprocates to bend the eye upwardly. The eyes may be bent during a dwell in the stitching. Alternatively, the plunger 26 may descend adjacent the row of stitching of the tape which passes over spaced anvils 24, 25. The eyes may pass between two rollers having a complementary ridge and groove. A cam on a driving-shaft may feed the tape and another cam operate the plunger. The tape may be fed to a reciprocating plunger intermittently by a finger on a lever pivoting on the circumference of a disc rotated by the driving- shaft. The finger engages each eye in turn.

Title: Improvements in or relating to printers
Filed: 1960-11-24
Abstract: 936,354. Typewriters &c. SIEMENS & HALSKE A.G. Nov. 24, 1960 [Nov. 25, 1959], No. 40422/60. Class 100 (4). A typewriter has a continuously moving type carrier and a driving member for the impression member or hammer moving continuously in constant relationship therewith. Impression is effected on paper 1 from a continuously rotating type wheel 2 by a hammer 43 actuated by a sprocket disc 42 rotating in synchronism with the wheel 2 and acting through a transmission member 45. A control device such as an electromagnet initiates an impression stroke acting as shown by an armature extension 44 which slides the transmission member into a position where it is contacted by the sprocket disc 42 and caused to transmit a printing stroke to the hammer 43 by pivoting about an edge 46b of a guiding component 46. This pivoting disengages the member 45 from the extension 44 and allows a spring 49 to restore the member 45 to the dotted line position where it is out of contact with the disc 42 so that after impression a spring 48 can restore the hammer 43. If the electromagnet has not restored the member 45 will contact the under surface of the extension 44 and a further impression cannot be made until the magnet restores and springs 47, 48, 49 can restore the parts to the initial position shown. Other electromagnetic control device arrangements are shown but in each case a single transmission member is moved by the control device to contact a constantly rotating sprocket disc and then to transmit a mechanical impulse directly to a hammer.

Abstract: 1276843 Control of D.C. motors ANTOMA (HAIRDRESSING) CO Ltd 19 Aug 1969 [28 Aug 1968] 41169/68 Heading H2J [Also in Division B6] A shunt-wound D.C. motor, which in operation drives a reciprocating carriage of a printing machine, is controlled by switches, actuated by the carriage, which connect the windings of the motor in such a way as to produce forward rotation, reverse rotation and dynamic braking. A three-phase electric supply is converted to D.C. by a transformer I and by rectifiers, and is applied to a field coil 35 and armature 36, Actuation of a starting switch FS causes a relay BCR to operate and close contacts BCl, and further relays cause the motor to operate forwards until the carriage trips a microswitch FMS. Current is then maintained through the field winding, while the rotating motor acts as a generator and passes a current through a dissipating potentiometer VR1. Any remaining voltage produced dynamically after a preset delay is discharged through contacts BW, bringing the motor to a dead stop. The armature is then fed with current in the opposite direction, and the motor reverses until the carriage trips a microswitch FMS and initiates a further cycle. The motor speed can be controlled by varying the voltage taken from the transformer I by way of switch 34. (For Figures see next page)
