Title: Copying milling machine
IPC: B23Q35/00
Filed: 1967-09-20
Abstract: A manually-controlled copy milling machine, Fig. 1, e.g. of the type having a pantograph 84 linking the tracer and cutter, is adapted for servo-assistance of the copying movements by means of a bearing arm 44, Figs. 1, 3, 4 extending from the tool carrier 36 and carrying servo control means 58, Figs. 1, 3 and 7, at an end portion thereof, the bearing arm 44 also supporting a pivoted lever 72, Fig. 4, through a further pivoted lever 68, Figs. 1, 3 and 4, which lever 72 at one end is connected rigidly to the tracer holder 80, Fig. 3, and at the other end carries a coupling pin 88, Fig. 7, which is rigidly attached to an input member 92 of the servo means 58. The tracer holder 80 has a coupling 82 for connection to the pantograph 84. Thus hand controlled movements of the tracer cause small pivotal or three dimensional movements of the lever 72 with corresponding input through the pin 88 and input member 92 to the servo means 58. For three dimensional copying the lever 72 is made vertically displaceable on its pivot. The servo means 58 preferably controls movements of the work-table 24 by means of hydraulic servomotors 16, 30, 32, Fig. 1, but may control feed of the tool carrier. If the work-table is servo controlled the tool support 36 is bolted up to machine column 10. If it is desired, e.g. for a finishing cut, to return to totally manually controlled copying the servo means 58 may be removed and a plug, Fig. 8, (not shown) attached in its place, this plug serving to connect the lever 72 rigidly and impivotably again to the bearing arm 44.

Title: Thermographic reproduction material and process
IPC: G03C1/60
Filed: 1967-12-14
Abstract: A thermographic process comprises reflex exposing to heat a material comprising a transparent natural fibrous support coated with a layer containing a diazonium compound or a quinone diazide but containing no coupling component to produce a positive destruction image which is opaque when viewed by transmitted light and a light image on a dark background when viewed by reflected light. The image may be fixed by uniform exposure to light. The heat-sensitive layer preferably contains an acid such as citric sulphosalicylic, tartaric or trichlorocetic acid (which releases acid gases on heating) and may contain a polymeric binder such as polyvinyl alcohol the presence of an acid aiding the destruction of the natural fibres and thus the formation of the image. The imaged may be used as a master for diazotype process as the destruction image is opaque to ultraviolet radiation.

Title: Concentration and purification of influenza viruses
IPC: A61K39/145
Filed: 1968-02-20
Abstract: Viruses of the influenza group, e.g. Myxovirus influencae-A, -B or -C are concentrated and purified by dialysing an aqueous suspension of the virus against water to an extent such that the virus forms a precipitate and separating the precipitated virus fraction from the supernatant solution. The concentration of bivalent metallic cations (e.g. Ca, Mg, Ba and/or Co) in the dialysis water is preferably adjusted to a value from 0.003 to 0.012 M. During dialysis, the conductivity of the suspension is reduced to below 3 x 103Á mho/cm. and the chloride content is reduced to 1.3 mg./ ml. or less. The virus suspension may be an allantoic fluid, obtained from embryonated infected hen's eggs, which has 'been clarified by low speed centrifugation before .the dialysis, which may be carried out in a kidney machine. The separated precipitate may be washed with a solution containing 0.1 M bivalent metallic cations, e.g. Ca the separated or washed precipitate may be resuspended in a buffer containing triammonium citrate. Influenza vaccines may be obtained by inactivating the viruses, e.g. with formaldehyde, before or after dialysis or using an attenuated strain of virus and presenting the concentrated virus suspensions in a pharmaceutically acceptable vehicle.

Title: Variable loss device
IPC: H03G1/00
Filed: 1969-10-30
Abstract: A variable loss network for a transmission line has a shunt path consisting of the emitter/ base circuits of two transistors T 1 , T 2 whose emitters are connected to the conductors of the line. The impedance of the shunt path is altered by injecting into the emitter electrodes of the transistors equal control currents from respective high impedance sources. Two transistors T 3 , T 4 provide this source and have their collectors connected to the respective conductors of the line and their emitters connected together and to a source of control potential. Reference potentials are provided for the bases of the transistors by divider R 3 , R 4 , R 5 . The injected control current can be provided from the output line by amplifier 2 and rectifier 1 when the network is used as an automatic gain control circuit. For a given value of circuit impedance the total control range is determined by resistors R 3 -R 7 and can provide compressor or expandor action. The transistors should be matched so that the balance to ground of the transmission line is not disturbed and opposite polarity transistors can be used if the polarity of the source is reversed.

Title: Circuit breaker polarised differential trip - has several coils wound on magnetic circuit to generate differential flux of specified direction
IPC: H01H71/32
Filed: 1977-11-04
Abstract: The polarised differential trip is intended for safeguarding the breaking of a circuit breaker or an isolating switch. It has to normally balance coils on a closed magnet circuit with two branches, a permanent magnet, and a moving armature for closing between the two branches. The trip is exposed to a resetting force, somewhat smaller than the attractive and holding force due to the magnetic flux generated by the magnet. The coils (13, 14) are so wound on the magnetic circuit that the differential flux, generated by them in the air gap, has an opposite direction to that generated by the magnet (12). The trip enables direct current application.
