Patent GB-840642-A (GB)
Title: Process and apparatus for the production of beaded filaments
IPC: C03C25/26
Filed: 1958-05-12
Abstract: Beaded filaments are produced by coating yarns with high viscosity plastisols, drying and heating, and then applying low viscosity plastisols followed by further drying and heating to cause the low viscosity plastisol coatings to contract and harden. Yarns of natural fibres, e.g. cotton, artificial fibres, e.g. regenerated cellulose and cellulose acetate, fully synthetic organic fibres, e.g. nylon and acrylic fibres, and inorganic fibres, e.g. glass and metal fibres, may be treated.  Polyvinyl chloride and copolymers thereof with other vinyl compounds, especially vinyl acetate and vinylidene chloride, plasticized with adipates of higher alcohols or mixtures thereof with phthalates of higher alcohols are preferred plastisols, and may be used as such or diluted with one or more higher aliphatic hydrocarbons.  The low and high viscosity plastisols preferably differ only in solution, although low viscosity plastisols having a basis of a different synthetic resin from the high viscosity plastisols may be used, it being preferable in this case to use the low viscosity plastisols in association with an anchoring compound, e.g. polyethylene imine or a poly iso cyanate.  Attractive effects may be obtained if the low and high viscosity plastisols have contrasting colours.

Title: Improvements in or relating to thickness measuring devices
IPC: G01B7/06
Filed: 1956-05-16
Abstract: 814,322. Thickness measuring apparatus. GENERAL ELECTRIC CO. Ltd., RUDGE, T. R., and TAYLOR, K. Aug. 16, 1957 [May 16, 1956], No. 15320/56. Class 37. A device for measuring the thickness of non- ferromagnetic material comprises a core of ferromagnetic material having portions which can be moved relatively to one another to form jaws between which the material the thickness of which is to be measured may be placed, means for magnetically polarizing the said core, and means adapted to be influenced by the magnetic flux across a gap in said core. Fig. 1 shows such a core with fixed member 2 and movable member 3 with a gap 29 and a polarizing magnet 28. Member 3 may be moved to the position shown by its broken lines by pressure on lever 20 which is spring-loaded to return member 3 to its original position. An indicating device (Fig. 2) comprises a soft iron member 33 pivoted at 34 with indicator 35 and loaded with a spring 36. The soft iron member is situated in the gap 29 and hence the position of the indicator is dependent upon the flux through the gap and hence the thickness of the material situated between the jaws 4 and 5 (Fig. 1). The polarizing magnet may be situated in a further gap in the core or the core may be polarized by means of a coil and D.C. current. The soft iron member 33 may also be replaced by a D.C. excited coil. In either of these two latter cases the coil may have a rheostat in series with it so that on separation of the jaws 4 and 5 the current through the coil may be adjusted until the indicator 35 resumes its normal position and in this case the setting of the rheostat is indicative of the thickness of the material being measured.

Abstract: 1,206,222. Cables. RUDOLF FUCHS MINERALOELWERK K.G. 1 April, 1968 [1 April, 1967], No. 15484/68. Heading H1A. The cavities formed on cooling in a cable having as impregnant a non-draining composition (i.e. solid at the operating temperature, but liquid on impregnation) are filled with a gas, previously dissolved in the impregnant, which has a higher breakdown voltage than air, oxygen, or nitrogen, and is more soluble than these in the impregnant, so facilitating higher cavity gas pressures and breakdown voltages. The gas may be monofluorotrichloromethane; 1,2,2-trifluorotrichloroethane; or tetrachloromethane; its solubility is at least five times that of air, and it gives a cavity vapour pressure of about one atmosphere at the operating temperature. The cable as prepared for impregnation is heated under vacuum, the gas being admitted before the impregnant to give a pressure of about 5 x 10<SP>-1</SP> Torr. More gas is supplied after the impregnant to give a pressure of 1 to 2 atmospheres, so that more dissolves in the impregnant, more then being supplied as the gas dissolves, to the extent that the pressure in the cable cavities after cooling is approximately one atmosphere.

Title: Improvements in or relating to electric traction arrangements
IPC: B60L3/00
Filed: 1938-05-24
Abstract: 515,117. Current collectors for electric vehicles. GENERAL ELECTRIC CO., Ltd., and CROFT, E. H. May 24, 1938, No. 15487. [Class 104 (lii)] In an electric vehicle provided with a pantograph collector engaging an overhead wire and adapted to be raised or lowered by a pneumatic &c. device, means are provided wherein, upon a control being effected to lower the pantograph, an electric circuit such as that of a compressor motor or a motor generator set, supplied from a trolley wire, is 'rendered inoperative. In the form shown in Figs. 1 and 2, each vehicle comprises a compressor and motor generator set, three supply wires 4, 5, 6, a common negative wire 7, a master switch 9 connecting the supply to the compressor motor through 4, a contactor coil 8, and interlock relay switch 31, 33, 34. The motor generator sets are controlled through a set contactor coil 11 and a trip contactor coil 12, and a master switch 13 which makes momentary connection between 5 or 6 and the main supply. Momentary energization of 6 may be effected also by contacts 32, 35, 36 on the interlock relay referred to above. The pantograph is operated by fluid pressure admitted to a cylinder by pipes 17, 19 and valve 15 when the coil 16 of the valve is energized. Fluid is also admitted by a valve 22 to a cylinder 24 for closing the interlock relay switches 31, 32. When the operator wishes to lower the pantograph, he de-energizes 16, so that valves 15, 22 connect the fluid cylinders to exhaust. The cylinder 24 being relatively small, opens the switches 31, 32 before the pantograph leaves the trolley wire, and so breaks the circuits of the auxiliary motors. In the fluid supply pipes are interlock valves 21, 30 connected to the vehicle doors and adapted when the doors. are open, to connect the cylinders to exhaust and open switches 31, 32. In another form, the stem 26 of the valve 15 operates the valve 22 through an interposed member which is withdrawn when the valve 21 is operated by the opening of the door, thus connecting cylinder 24 to exhaust. In another form, an interlock relay switch is mounted on the spindle of the valve 21, and opens the circuits when the door is opened.

Title: Unbalance correction
IPC: G01M1/22
Filed: 1974-04-09
Abstract: 1464003 Measuring rotary unbalance electrically AVERY-DENISON Ltd 9 April 1974 [27 Sept 1973] 15604/74 Heading GIN [Also in Division G4] In order to obtain the angle and magnitude of unbalance of a body, e.g. a wheel, signals U sin a and U cos a representing the unbalance is fed via leads 1, 2 to a co-ordinate transformation device 5 to which a transformation angle c is applied by a counting device 10 operating under control of one of the output signals on lead 6 of the co-ordinate transformer 5 in such a manner that when this signal is equal to zero, the angle c is equal to the angle a and the output on the second output lead 7 is equal to U. The value of U is displayed on a meter 18 and the value of c = a on either a digital display 13 or a meter 14. The counting unit 10 consists of a counter 10a counting the three highest values and controlling via decoding unit 21 2 and switches 207-210 the values of input resistances 211 of feedback amplifiers 201, 202. These are fed with the signals U sina, U cos a which are inverted if  necessary by amplifiers 205, 206. The values of the resistances are such that the inputs are rotated through a fixed angle of 22¢ degrees and then through steps of 45 degrees. A further stage 5b, controlled by a 6-bit counter 10b, which divides the octant into 64 stages. The counting device responds to comparators connected to output leads 6, 7 which detect zero on lead 6 and also respond to the sign of the output on lead 7 (see Fig. 4, not shown). If the latter is negative, the logic circuit causes the counter 10 to advance and rotate the co-ordinate by 180 degrees. A comparator is used to produce a signal for initiating a machining process. In order to obtain a signal for positioning the body for correction, the counter 10 is stopped in the position corresponding to c = a. A code disc attached to the body is scanned and the orientation angle d of the body is subtracted from c. The difference is fed to a D/A converter which produces a positioning signal. The angular setting d is determined in the same manner as the angle a viz by feeding signals sin d and cos d to the co-ordinate transformer. Values defining zones where machining is not possible are fed to a corrector unit 41 connected to the counter 10 and to an adder 40 where correction signals are added to the value of the angle a. A signal is also fed from the corrector unit 41 to the unbalance magnitude store and a pre-set factor is applied to the measured magnitude.
