Title: Arrangements for synchronizing magnetic recording of television signals
IPC: H04N5/782
Filed: 1962-03-19
Abstract: 946,169. Automatic speed control. LOEWE OPTA A.G. March 19, 1962 [March 21, 1961], No. 10366/62. Heading G3R. In a synchronizing arrangement for the recording and playback of television signals on magnetic tape, a motor driving the recording heads is driven in synchronizm with the said signals and a motor driving the magnetic tape is uncontrolled, while on playback, either (a) the head motor is controlled by synchronizing pulses and the tape motor is uncontrolled or (b) the tape motor is controlled by synchronizing pulses and the head motor is uncontrolled. As shown, Fig. 1, a recording head 4 driven by a motor 5 receives signals from television set 1 over an oscillator 2 and an amplifier 3. The signals are also applied to a phase shifter 6 and to a phase reference control 13 which also receives a signal which is dependent upon the speed'of the motor 5 and which is derived from a photo-cell 11 illuminated at each revolution by the light reflected from a-source 10 by a mirror 9 rotating with the head 4. The rotation of the head 4 is thus compared with the television signal, any divergence producing a control output from phase shifter 6 which is applied over an amplifier 7 to motor 5 to restore synchronizm. A head 14 for recording synchronizing pulses on the tape also receives the signal from amplifier 7. The tape is driven by an uncontrolled synchronous motor 8 which is connected directly to the mains supply. On playback, Fig. 2, the tape motor 21 is connected directly to the mains supply, and the motor 16, driving the head 15 producing the signal applied to a television set 20, is kept in synchronizm with the signal by means of the synchronizing pulses which are picked up by a head 22 and applied to the motor 16 over an amplifier 23, a phase shifter 24, and a further amplifier 25. The embodiment having an uncontrolled head motor and a controlled tape motor is described with reference to Fig. 3 (not shown).

Title: Improvements in or relating to cutting and abrading tools
IPC: B23D73/00
Filed: 1951-05-03
Abstract: 695,830. Making files, milling and planing cutters, graters, &c. BOOTH, C. H., and HARDWICK, H. B. April 29, 1952 [May 3, 1951], No. 10448/51. Classes 83 (ii) and 83 (iii). [Also in Group XXIII] A cutting element, similar to those described in the parent Specification and Specifications 666,573 and 666,622, for use as a file, rasp or cutting band, disc or drum, is made by upsetting parallel rows of spaced tongues 7 from a flexible sheet or strip of hardenable steel or iron alloy, removing, e.g. by grinding, the upset free ends of the tongues parallel to the surface of the blank to form sharp edges 11, Fig. 5, bending the blank in one direction along lines within the length of the tongues and reversely bending it along lines between the rows of tongues so that the blank is corrugated with the tongues protruding at a suitable cutting clearance angle, and finally hardening the cutting edges. The ridges of the corrugations provide non-cutting surfaces which rub on the work and prevent the edges from digging in, as described in Specification 695,859. D-shaped holes 9 are first punched out ahead of the tongues and the tongues are upset to a greater extent than finally necessary, in order to free the edges of the slits 10, and then pressed back to the desired degree of upset; this upset is generally a little more than the thickness of the material but may be varied to give different included angles c, Fig. 5, between the sides forming the cutting edge. By adjusting the relative positions of the bending dies 12, 13, Fig. 9, so that the front bending line is moved further back from the cutting edge, the extent to which the edge protrudes may be increased, and by varying the sharpness of the bends, the rake and clearance angles a, b, Fig. 11, may be varied. The strip may be surface-hardened by cyanide treatment and quenching or by gaseous diffusion of tungsten, cobalt or molybdenum and chromium, or may be hardened throughout and the ridges of the corrugations tempered to provide flexibility. Burrs on the sharpened edges are removed by sand-blasting. The strip may be bent to convex form to provide a half-round file, the corrugations being formed before or after bending to convex form. Cutting edges may be formed on both sides of the strip, preferably at opposite sides of rectangular holes, with the edges at the tops of the reverse bends. Specification 695,821 also is referred to.

Title: Improvements in or relating to straight-bar knitting machines
IPC: D04B11/00
Filed: 1944-06-01
Abstract: 585,220. Knitting-machines. BLACKBURN & SONS, Ltd., G., START, H. W., and START, E. June 1, 1944, No. 10539. [Class 74 (ii)] To eliminate the draw cam brake and provide a robust disengageable connection with the draw mechanism, the draw cam of a straight bar knitting-machine is secured to the main cam shaft C so as to move laterally therewith and actuate a draw lever consisting of two arms. One arm D is connected to the reciprocating parts of the machine. The other arm E carries a truck H permanently engaged with a groove B in the draw cam disc A, and is connected to the arm D by a connection which is disengaged when the cam shaft is moved laterally to bring the narrowing cams into operation. Arms D and E are pivoted on a common shaft F along which, when the cam shaft C is shogged, the lever E is constrained to slide, by the engagement of key J on the boss E' of the arm in a groove A' in the disc A. To ensure that the arm E slides freely, the boss E<1> is formed with an arm E<2>, the end of which is secured to a collar K slidable on the shaft F. The driving connection between levers D and E may comprise a rib on the side of one arm, engaging between two ribs on the adjacent side of the other arm. 'In the construction shown, the first rib is formed as a member L, pivoted at M to the arm E and located in a groove therein. The member L is urged by a spring L<1> to engage a groove D' in the member D, its movement being limited by a tail L<2> which abuts against an adjustable screw L'. The spring enables the member L to yield if it should be out of alignment with the groove D' when it is to be re-engaged. To provide for the easy engagement of the member L in the groove D<1>, the depth of the lower wall of the groove is made less than that of the upper wall. If the cam shaft C is shogged when the arm D is raised, the rod G connecting the arm to the reciprocating parts of the machine is supported by engagement of the free end of a lever N below a stop G' on the rod. The lever N is pivoted at N'. Its other end carries a truck N<2> engaging with the face of the cam disc A and, as the cam disc is shogged away from the truck, a spring O rotates the lever to bring its end under the stop G'. Alternatively, a forked end of the lever N may embrace a disc on the cam shaft and a lateral extension on the other end of the lever may support the arm D on any other convenient part of the draw mechanism. Provision may also be made for holding the arm D in its lowest position. Instead of being pivoted on the shaft F, the arm E may be pivoted on a bracket slidable on the machine frame and movable with the cam shaft.
