Patent GB-889733-A (GB)
Title: Improvements relating to inductive loop communication systems
Inventor: LESLIE JOHN ANGUS
IPC: H04B5/00
Filed: 1960-12-02
Abstract: 889,733. Inductive signalling. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 2, 1960, No. 41572/60. Class 40(5). In a two-way inductive signalling system signals from a microphone 9 at a fixed station A are fed via an amplifier 2 and transformer 7 to points 3 and 4 on an inductive loop 1, the point 3 being a tap on the primary winding of a transformer 6 arranged so that the resultant flux is zero for the signal currents from the fixed station flowing in opposite directions through the two portions of the primary winding. In this way feedback via the secondary winding 8 of the transformer 6 to the amplifier 2 is avoided. The signal currents in the two halves of the loop 1 are received by pick-up coils 11 and affect signal-responsive devices at mobile stations B, C. If either of stations B, C wishes to communicate with the other or with the fixed station, signal currents impressed on a coil 11 circulate in the loop and via the transformer 6 are supplied to the amplifier 2 and reproduced at 10. The amplified signals are also supplied back to the loop via the transformer 7 for reception by the other mobile station.

Filed: 1971-09-07
Abstract: 1354977 Preparing spectroscopic samples TECHNICON INSTRUMENTS CORP 7 Sept 1971 [14 Sept 1970] 41647/71 Heading G2J Gaseous samples for spectrascopy are prepared by a burner 24 in which the sample drops 49 are heated and atomized; those drops being emitted from a supply pipe which may be vibrated. A lamp 60 is provided to allow absorbtion spectra to be determined at 68, or fluorescence of the sample may be monitored with the light off. In various embodiments two samples may be presented successively and two lights used. The appropriate filter to allow detection of the various spectra are also introduced into the detection path, automatically. The samples may be "scanned" as by an electric field on plates 122, 124 to give an A.C. signal at the detector. Pulse modulation may also be used for this purpose.
Patent GB-416996-A (GB)
Abstract: 416,996. Thermal switches; automatic circuit breakers. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin.) May 8, 1933, No. 13364. Convention date, May 7, 1932. [Class 38 (v).] A switch 27, 29 for closing the motor circuit of a compression refrigerator is moved on and off in accordance with the temperature of the refrigerating chamber by means of a bellows 1 acting on a sleeve 4 against the action of springs 6, 9 which are adjusted, so as to vary the temperature maintained, by rotating a knob on the spindle 3 ; the knob is adapted to be latched in a number of positions corresponding to different temperatures, and may be released from such positions either by backward rotation of the knob by hand or by an overload cut-out; it then returns to an off position in which it holds the switch 27, 29 open. The sleeve 4 acts on a lever 31 pivoted at 34 and connected by a dead-centre snap device 32 to the contact arm 29 pivoted at 28. The sleeve 4 carries a washer 5 which bears on the spring 6 and the upper end of the spring 6 is also acted upon by a barrel 10 pressed downwards by the spring 9, the upper end of which is raised or lowered by rotating a screw 12 actuated by the knob. The screw 12 is loose on the spindle 3 but is fixed to a wheel 14 having a small degree of lost motion relative to a wheel 15 fixed to the spindle, and the action of the spring 9 on the nut 11 tends to rotate the screw 12. The wheels 14, 15 both have teeth and the teeth on the wheel 14 engage a catch 21 which holds the wheel in any selected position. The catch may be released either by the bending of a bimetallic strip 25 heated by a coil carrying the motor current when overload occurs or by rotating backwards the knob and therefore the wheel 15, a tooth on which then presses back the catch 21. A pin carried by the wheel 15 and moving in a slot 18 in the wheel 14 to provide the above-mentioned lost motion also is adapted to engage the end of the contact arm 30 to open the switch when the handle is in the off position.

Title: Improvements in or relating to apparatus for controlling valves and/or pumps
IPC: G01N23/08
Filed: 1959-12-11
Abstract: 929,305. Nuclear radiation control apparatus. U. PASSAVANT, and P. SCHRAMM, [trading as PASSAVANT-WERKE]. Dec. 11, 1959 [Dec. 13, 1958], No. 42288/59. Class 40 (3). Apparatus for controlling valve means in ducts or pipes and/or pumping means in dependence upon the solids content of collected liquors flowing through said ducts or pipes, particularly of sludges in the disposal of sewage, is characterized by the provision of a radioactive source of corpuscular or wave type radiation, an instrument such as a Geiger counter for measuring said radiation, an examining section or flow path for the liquor through which the radiation passes, in the axial direction, and an indicating means operated by the instrument which measures said radiation said indicating means controlling relays or switches which control an electric motor operating the valve and/or pumping means. In the arrangement indicated in Fig. 1, radiation from an isotope 6 in an axial chamber 7 in a lead sphere 5 passes axially through a channel 12 in a fitting 11 and the liquid in a horizontal section 3 of a U- shaped pipe to a Geiger counter 20. In the diagrammatic system shown in Fig. 3, the liquid in the container 22 can pass through a valve 26 operated by a motor 25 and through a pipe 28 leading from an upper part of the container 22 and valve 30 to a vertical pipe M2 through which radiation passes from an emitter 31 to a Geiger counter 33. A horizontal beam M1 passes through the liquid to a Geiger counter 32. When the liquor in the container 22 reaches a desired turbidity, a pulse from the counter 32 operates an amplifier 34 and relay system 36 which actuates switches 37, 38 to control the motor 25 to open valve 26 and a pump 27 to withdrawn liquor from the container 22. If the density of the sludge indicated by pointer 42 of a regulator 39 exceeds a predetermined value set by pointer 41, a pulse is passed from the regulator 39 to an auto-switch 40 which controls a motor 29 to open a valve 30 to allow water to pass to the tube M2 and outlet pipe 24. If the density falls below the predetermined value, the regulator 39 passes a pulse to the relay system 36 and through the switch 38 to throttle the valve 26, and if the value falls below a predetermined minimum value the valve 26 is completely closed and the pump 27 is stopped by the auto-switch 37, the system remaining inoperative until the examining section M1 detects sufficient depth and density of sludge to initiate the recommencement of the withdrawal of sludge from the container 22.

The switching network preferably comprises primary and secondary cross-bar switches. Fig. 3 (not shown), and the link circuits may provide a feed bridge. The registers may be available from the link circuits, or in a modification may be included in the common multiple. After a seized register has recorded the identities of the lines to be connected together, it transfers the records to a common marker which set up a fresh connection through the network, the register being released. If required, some of the trunks may be connected to the secondary switches.

A process for producing film patterns comprises applying an amorphous photo-chromic layer of a spiropyran to a support, imagewise exposing to ultraviolet light, removing either the unexposed or exposed areas of the photo-chromic layer, applying a metal, di-electric or semiconductive film which is more adherent to the support than to the photo-chromic image, applying a pressure-sensitive adhesive tape and removing the tape and the film overlying the photo-chromic image areas to leave an image of the film which is directly applied to the support. Specified supports are glass and glazed ceramics and specified materials are metals such as chromium, nickel, tantalum, permalloy, tin, titanium aluminium, silicon monocide, cadnium selenide and germanium. In the examples, a glass support is coated with a solution of a mixture of benzoindiolinospiropyrano, imagewise exposed and developed with a non-polar solvent to removed the unexposed areas, cleaned by glow-discharge and the layer of metal 1000 thick sputtered on under reduced pressure, a pressure-sensitive adhesive tape applied and pulled off removing the photo-chromic image and overlying metal leaving a metal image on the glass. A gold layer may be sputtered over the metal layer and after removal of the photo-chromic image, the glass support may be etched. Alternatively, the photo-chromic buyer may be uniformly exposed and ultraviolet light imagewise exposed to light of 6328 and imagewise exposed areas removed.
