Patent GB-1106010-A (GB)
Title: Conducting layers at the surfaces of insulation layers
IPC: H01B13/30
Filed: 1965-08-02
Abstract: A process of producing a conducting layer on the outer surface of a thermoplastic synthetic resin insulation layer comprises applying to the external surface of the resin a dispersion of a fine-grained powder wherein the liquid is such that it becomes permanently absorbed into the resin and so leaves the fine-grained powder to form at the external surface of the said conducting layer, wherein the absorption of the liquid increases the resistance to glow discharge and the destructive strength of the resin, and wherein the dielectric constant of the liquid is substantially equal to that of the resin. The particles may be of carbon black or graphite and the synthetic resin may be polyethylene.  The liquid constitute 50-70% by weight of the dispersion and may be an aromatic hydrocarbon containing two benzene nuclei linked directly or through a carbon atom.  Liquids specified are bisbenzyl toluene, dimethylisopropylebenzene, dodecylbenzene, a low molecular weight polymer of trifluoromonochloroethylene and hexachlorobutadiene.  For insulations consisting of high-pressure polyethylene, paraffin oils may be used and for polyvinyl chloride insulation, fatty acid esters and benzoic acid esters are specified.  Anti-ageing compounds such as amines or phenols may be added to the dispersion.  The dispersion may be heated before application and may be applied to the hot surface of the insulating layer immediately after it has been applied.  The dispersion may be applied as a spray or the insulating layer may be passed through a bath of dispersion which thereby may act as a cooling bath.  The dispersion may be applied immediately the layer leaves the mouthpiece of an extrusion machine.  In the apparatus shown, covered cable 5 leaves an extrusion machine (not shown) and the suspension is sprayed on from nozzle 4 and excess returns to vessel 1.  Surplus dispersion still adhering to the cable is removed by the stripper 6 in the form of a foam sponge.

Title: Scanning and curve following device
Inventor: SICK ERWIN
IPC: B23Q35/128
Filed: 1970-07-09
Abstract: 1300337 Photo-electric curve followers E SICK [trading as ERWIN SICK 9 July 1970 [9 July 1969] 33284/70 Heading G1A [Also in Division G3] A sine/cosine resolver 6 fed with a sinusoidal signal is coupled to a photo-electric scanner, (not shown), which is rotatably positioned tangentially to a line being followed, by a servomotor responsive to a first scanning signal. The amplitude modulated signals from the resolver are converted to frequency-modulated signals in a device 71 and then fed to a demodulator 8 wherein they are integrated over a half cycle to provide coordinate output signals over lines 12,13 for movement along the line at a constant rate. Lateral deviation from the line is determined as a second scanning signal 11 which modifies the phase of the signal from a wave-shaper 9, fed from a resolver reference source 5, in a device 10 which is used to shift the integration half cycle of the demodulator 8 with respect to the reference source by the lateral deviation angle, whereby the velocity of the scanner along the line is maintained constant. In another embodiment, the amplitude modulated sine and cosine resolver signal are fed to pairs of demodulators which are fed with phase shifted reference signals derived from the output of device 10 through a quadrature element. The cross-connected outputs of the demodulators are summated or differenced to derive the co-ordinate positioning signals on lines 12, 13. The photo-electric scanner is of a conventional form and comprises three diodes, the first of which is mounted on the centre of rotation of the scanner, the second radially to define the tangent of the curve and the third is half-obscured and provides a reference, to enable differential signals to be derived. The differential signal from the second and reference diodes is used to tangentially rotate the head and the differential signal from the first and reference diodes is fed to a sine-cosine generator driven by the scanner. The generator provides signals to energize X, Y axes drives for positioning the scanner. Alternatively, the rotatable scanner incorporates two parallel strips of photo-responsive material, disposed parallel to one another, scanning through a vibrating mirror. Phase related signals are obtained one being used to tangentially rotate the head and the other'to affect lateral deviation. Both signals are used to control servomotors via resolvers for positioning along X, Y axes.

Abstract: 377,879. Stop-motions for yarn-winding machines. McKEAN, J. 0., 82, Court Street, Westfield, Massachusetts, U.S.A. Dec. 7, 1931, No. 33912. Convention date, Dec. 6, 1930. [Class 120 (ii).] A stop-motion for winding-machines is provided with a tripping-mechanism in which a kicker cam engages a tripping-roller adapted to be moved into its path when the yarn breaks or becomes exhausted. A rocking arm 3, 5 carrying the package 2 to be wound and limited in its downward motion by a stop 46, is pivoted to a rack bar 7 supported by a depending arm 10 of a two-armed lever adapted to rock about a pivot 11, movement of the lever being limited by a stop 14 held in engagement with a frame bar 15 by a spring 13 secured to the other arm 12 of the lever and to a latch member 24 rockable on a pivot 25. A rocking arm 22, pivoted to the upper end of the latch member 24, carries at opposite ends a detector 21 and an eccentrically mounted fibre roller 26. Normally the detector 21 is depressed by the yarn 40 but cessation of supply or breakage of the yarn allows it to rise and bring the roll 26 into contact with a kicker cam 20 on the traverse shaft 19. The cam then rocks the latch member 24 and frees a catch in its lower portion from a pin 35 on one arm 27 of a threearmed lever 27, 28, 29. A spring 30 connected to the arm 28 rocks this lever raising the arm 27 and a hand-lever 32 thereon and bringing a projection 43 on the lever into engagement with a lug 42 on the rack-bar arm 10 ; the arm 10 then pulls the rack bar 7 to raise the package 2. To re-start the device, the handle 32 is fully depressed causing a hook pin 33 on the arm 29 of the three-armed lever to raise the rack bar clear of the engaging tooth 9 on the arm 10. Simultaneously a clip 47 on a stop-motion cover 34 pivoted on the pin 35 and adjustable against the main frame by a screw 37, depresses the detector 21. When winding has commenced and the yarn has engaged the depressed detector 21, the handle is released and rises slightly until the latch 24 engages the pin 35. The cover 34 carries a yarn bar 36 which raises the yarn from, or lowers it into, a traverse guide 17 when the handle 32 is raised or lowered.
