Title: Apparatus for stripping fibres
Inventor: GROSBERG PERCY
IPC: D01H5/24
Filed: 1964-10-10
Abstract: 1,107,786. Stripping fibres. NATIONAL RESEARCH DEVELOPMENT CORPORATION. 21 Oct., 1965 [10 Oct., 1964], No 41466/64. Heading D1N. Apparatus for stripping fibres, e.g. from the spiked rollers 10, 11 of a wool opener, comprises a spiked moving member such as a spiked belt 12 and a flexible perforated member such as a belt 13, the belt 13 being guided so that in one area the spikes on belt 12 passed through the perforations therein while in another area the belt 13 moves off the spikes carrying fibres with it. The spiked member may constitute part of the processing apparatus. Belts 12 and 13 come into close engagement as they pass over a roller 16, drive being transmitted from the roller to the inner belt by grooves 27 on the roller and ridges on the inner belt. These ridges may be formed by the backs of staples constituting the spikes. Alternatively the inner belt may be formed with the ridges. The inner belt passes over an adjustable roller 17 while the outer belt passes over an adjustable roller 21 and a fixed roller 22, the arrangement is such that the angle of divergence between the belts as they move apart is less than 30‹. The cosine of this angles is approximately equal to the ratio of the pitch of the spikes at their roots and the pitch between the spikes at positions along the spikes where the perforated belt lies when the belts are passing about roller 16. In this way the holes in belt 13 need not be elongated to allow the belt to withdraw from the spikes. In a further form (Fig. 3, not shown) the spikes are mounted on transverse bars carried at their ends by chains.

The holes 24 are oblique with respect to each other and lie in a plane generally parallel to the plane of the disc 10.

Title: Improvements in or relating to electro magnetic transducers
IPC: H04R11/12
Filed: 1962-11-20
Abstract: 1,033,722. Stereophonic pick-ups. W. O. STANTON. Nov. 20, 1962, No. 43936/62. Heading H4J. In a variable reluctance pick-up for use with stereophonic records, core members 54, 55, 56, 57 (Fig. 3) are surrounded by coils and each core member has a pole face 54a, 55a, 56a, 57a, these faces being in use inclined substantially at 45 degrees to the horizontal. The pick-up also includes a permanent magnet 62 formed with a V-notch which engages a V-cross-section brass mounting member 64 (Fig. 5). Mounting member 64 supports a magnetically conductive coupler 65 formed of high permeability material and also of V-cross-section. The ends of the coupler 65 terminate short of the pole faces. A spring mounting wire 66 is brazed to mounting member 64 and to a hollow cylindrical armature 63 carrying a stylus 67. The coils 58 and 59 are connected in series aiding relationship for signals generated by movement of armature 63 and in hum-bucking relationship for extraneous fields. Coils 60 and 61 are similarly connected. The coupler 65 provides a path, whereby flux can flow into the armature 63 over an extended length, and acts to reduce cross-talk. Cross-talk may be additionally reduced by making the included angle between the pole faces slightly in excess of 90 degrees such that movement of the adjacent part of the armature in a direction perpendicularly towards one pole face will produce a movement of minor order of the armature towards the other adjacent pole face (Figs. 8, 9, not shown). The pick-up may have a replaceable stylus assembly 100 (Fig. 12). Embedded in the supporting structure 99 are cores 102, 103, 104, 105, associated coils 106, 107, 108, 109 and a permanent magnet 110 (Fig. 13, not shown). Each core terminates in a flat lower surface. When the stylus assembly is in position the base of the permanent magnet engages the face 110<SP>1</SP>a of an extension member. Pole members provided with faces 102<SP>1</SP>a, 103<SP>1</SP>a, 104<SP>1</SP>a, 105<SP>1</SP>a engage the bases of the cores 102, 103, 104, 105. The stylus assembly 100 carries a V-cross-section mounting member, a magnetically conductive coupler and a hollow cylindrical armature carrying a stylus. An alternative form of replaceable stylus assembly (Figs. 21, 22, not shown) has an armature which co-operates with identical front and rear core coupling members 129 (Fig. 23). Faces 131b, 132b co-operate with the armature and a magnetic shunt 133 is arranged between the polepieces 131, 132 in such manner as to divert a portion of the flux flowing between the armature and one of the polepieces to the other polepiece, whereby cross-talk is reduced. Two replaceable stylus assemblies may be removably mounted on opposite sides of the supporting structure of the pick-up for use where the pickup is required to play either side of a record supported on a rotating arbor, as in a " juke box " (Fig. 11, not shown). Reference has been directed by the Comptroller to Specification 884,335.

Abstract: 1,191,128. Transistor sawtooth circuits; automatic phase control. R.C.A. CORPORATION. 3 Oct., 1967 [3 Oct., 1966], No. 44886/67. Headings H3A and H3T. [Also in Division H2] In a television receiver a deflection output stage has regenerative feedback via a transformer 32, the feedback winding 32b being coupled to the input of the output stage 30 via a capacitor 37 and under control of a switching transistor 29. The circuit shown is preferably employed to feed horizontal deflection coils 14 and is controlled by an astable multivibrator 27 which produces a substantially square wave output, the positive half cycle of which turns on transistor 29, which, in turn, turns off the output transistor 30 to initiate the flyback. After a quarter cycle of oscillation of components 14, 43, the base/collector path of transistor 30 becomes conductive, forming with diode 39 a damping circuit which provides a current path for the linearly declining current in deflection coils 14 during the first half of each sweep. Prior to the time at which the deflection current reaches zero, the multivibrator 27 turns off transistor 29 thus allowing the regenerative coupling via winding 32b to turn on transistor 30 so as to generate the second half of the sweep. Deflection amplitude stabilizing and protection arrangements.-The vertical deflection circuit (not shown) may be supplied from the junction of components 33, 34; decoupling resistor 33 being selected so that the effect of changes in intensity on the E.H.T. supply (provided by diode 41) are compensated by the change in deflection magnitude in such a way that the picture size remains unchanged. Resistor 33 also arranges transistor 30 to be cut off if it is brought out of saturation by high-voltage arcing. A clamping diode 44 and capacitor 45 protect transistor 30 against excessive collector voltages. The voltage across capacitor 45 may be supplied to one of the grids of the cathoderay tube. Automatic phase control.-Line synchronizing pulses are applied to the base of transistor 19 of a phase discriminator 18 and are compared with flyback pulses derived from winding 32b and fed to the emitter of transistor 20. Complementary transistors 19, 20 are regeneratively coupled so that they only become conductive during the simultaneous presence of both pulses and remain conductive until the voltage fed to the emitter of transistor 20 becomes reversed. The output of the phase detector 18 is arranged to control the frequency of the multivibrator 27 in such manner that the start of the retrace is arranged to occur three or four Ás. after the occurrence of each synchronizing pulse.
