Title: Apparatus for use in monitoring the level of the free surface  of an electrically-conductive liquid
IPC: G01F23/26
Filed: 1973-03-01
Abstract: 1422613 Measuring liquid level electrically INTERATOM INTERNATIONALE ATOMREAKTORBAU GmbH 1 March 1973 [3 March 1972] 10097/73 Heading G1N In the measurement of the level of an electrically conductive liquid (liquid metal) using an elongate transformer dipping into the liquid a temperature compensating circuit is connected to the secondary. The transformer, Fig. 1 (not shown) comprises monofilar primary and secondary windings wound in respective helical grooves formed in an elongated core so that respective turns of the primary and secondary windings alternate along the core with each turn of the secondary winding spaced apart along the core from two adjacent turns of the primary winding by equal respective distances. Temperature compensating circuit: The output of the secondary winding when the probe is dipped into the liquid is dependent not only on the level but also the liquid temperature. To compensate for this the output of the secondary winding L E , R E  (primary winding L S  R S  being energized from circuit II) is fed via capacitor CE to a filtering and rectifier circuit and a liquid level dependent voltage UpV varying inversely with the liquid level is derived from potentiometer P v . This voltage is combined with an auxiliary voltage from potentiometer P v  which is selected so that the combined voltage is zero when the probe is at a low temperature and does not extend into the liquid, the combined voltage in operation then being applied to one input of amplifier V2. The temperature of the liquid is monitored by its effect on the resistance of the winding R E , L E  and to this end a constant current is applied to the secondary through RKS and choke D1 and the voltage drop developed across 100, 90 is applied to the inputs of amplifier V 1. Thus amplifier V 1 provides an output which is proportional to the potential and hence temperature. The output of V1 is fed via R LK  to the input of amplifier V2 and also to an input U LK(x)  of a multiplier to a second input of which is fed the partially temperature compensated signal from the output of amplifier V2. The multiplier provides at output UK a further compensation voltage, produced by multiplying the two inputs together, which is fed to an input of amplifier V 3  to which is also fed the partially temperature compensated signal from amplifier V 2 . The output of amplifier V3 provides the temperature compensated level signal. In order to balance out the effects of the supply lead resistances Rz a constant current is supplied to one set of leads and a supplementary pair of leads are provided to apply the resulting voltage drop across the coil to the amplifier whose output is connected to 110, Fig. 3 (not shown).

Title: Multicolour printing
IPC: G03G15/01
Filed: 1966-03-08
Abstract: 1,132,216. Printing processes. INTERCHEMICAL CORP. 8 March, 1966 [7 June, 1965], No. 10111/66. Heading B6C. In a method of multicolour printing two or more differently coloured powder images are transferred sequentially by electrostatic forces from two or more different printing plates or cylinders to the surface of an offset member to form a multicolour image thereon and then the multicolour image is offset in a single transfer on to a desired substrate. The final transfer may be by electrostatic forces or by heating the substrate such that the powder sticks to its surface when contact is made. The printing plates may be of gravure or planographic form. As shown powder is supplied to electrically grounded gravure cylinders 10 from hoppers 13 by rotating brushes 14, excess powder being removed by doctor blades 15. The powders are charged by corona units 16 and 17, and transferred to charged offset cylinder 11 to form the multicolour image which is printed on to paper or other flexible sheeting 19 running over charged impression cylinder 12. Offset cylinder 11 may or may not be in contact with the material 19. Corona wires 18 and 20 may be used to charge the offset and impression cylinders. Transfer of the multicolour image to the material 19 may also be carried out by reversing the charge on the powder after transfer to the offset cylinder and grounding the impression cylinder. The impression cylinder and material 19 may be replaced by a bottle to which a potential is applied to transfer the powder image from the offset cylinder, adhesion of the image to the bottle being assisted by employing a pre-heated bottle.

Abstract: 1,175,475. Theodolites. VSESOJUZNY NAUCHNO-ISSLEDOVATELSKY INSTITUT GORNOI GEOMEKHANIKI I MARKSHEIDERSKOGO DELA. March 4, 1968, No. 10331/68. Heading G1F. In a theodolite having a telescope 7, azimuth and elevation angles are recorded on a photographic film 27 after conversion into a digital code a common code disc 3 in the form of a stationary horizontal plate being employed for conversion of both asimuth and elevation angles to be recorded. The disc 3 is disposed inside a casing 5 which is mounted for rotation about a vertical axis through the centre of the disc. A lamp 10, with condenser lens 11 passes light through the disc 3 and co-operates with a slit 14 and an optical system consisting of prisms 12, 25, 26 and lenses 24 to project an image of the slit 14 and thus a coded representation of the azimuth position of the casing 5 on to the film 27. The telescope 7 is rigid with a shaft 6 carrying a diaphragm 18 with a slit 19. A lamp 15 with condenser lens 16 and prism 17 cause light to pass through the slit 19, to an objective lens 21, prism 22 and then by way of prisms 12, 25, 26 to the film 27. The lamp 15 and its optical system up to the lens 21 rotates with the diaphragm 18 so that the position of the image of the slit 19 on the coding disc 3 will be indicative of the elevation angle of the telescope and this image will be recorded on the film 27. A limited range of elevation angles only can be covered by this arrangement, but a series of slits may be provided around the diaphragm 18, the ordinal number of each slit being provided as a digital code on the diaphragm in close proximity to the corresponding slit to show on the film 27 which of the slits is being used. In use the telescope is sighted on an object and then both lamps 10, 15 are illuminated to produce a record in digitally coded form of the azimuth and elevation angles of the telescope on the film 27.

Title: Centrifuge apparatus
IPC: B04B9/10
Filed: 1976-03-16
Abstract: 1480573 Centrifugal separator BECKMAN INSTRUMENTS INC 16 March 1976 [9 April 1975] 10373/76 Heading B2P [Also in Division F2] A centrifuge rotor safety device in the form of a hub member for attachment to the bottom of a centrifuge rotor has an opening for receiving a rotor drive shaft and a plurality of relatively heavy portions disposed around the opening and interconnected with rupturable web portions, the latter being so designed and constructed as to rupture under the centrifugal force created by the heavier portions when the hub member is rotated by the drive shaft at a predetermined rotational velocity. In its preferred form, the hub member 14 is a -disc-shaped body having radially extending slots 32, 32a partially dividing the body into oppositely disposed semi-circular sections 31, 31a attached to each other by thin web sections 33, 33a. The hub member 14 is attached to the bottom of a centrifuge rotor 10 by bolts 34 positioned through holes 36 in the sections 31, 31a of the hub member 14 and threaded into holes 37 in the bottom of the rotor 10. If the rotor 10 is rated at, for example, a rotational speed of 50000 r.p.m. and it will explode at, for example 70000 r.p.m., the hub member 14 is so designed and constructed that the centrifugal force asserted by the heavier sections 31, 31a will be sufficiently great at 55000 to 60000 r.p.m. to cause the thin web sections 33, 33a to rupture. When this occurs, the heavier sections 31, 31a move away from the central opening 16 of the hub member 14 and there is no longer any friction and consequently no driving force between the drive shaft 12 and the hub member 14. Under such forces the rotor 10 and hub member 14 depart from the shaft 12 at a speed below that at which the rotor 10 might explode. While the rotor 10 will thrash around inside the chamber 15, it will be retained without fragmenting. In order to reduce the force necessary to overcome the restraining effect of the bolts 34 on the heavier sections 31, 31a of the hub member 14, the holes 36 are formed with counterbore portions 36a. The spaces 36b between the bolts 34 and the sidewalls of the counterbore portions 36a of the holes 36 permit some movement of the heavier sections 31, 31a when there is a rupture of the thin web sections 33, 33a. On movement of the heavier sections 31, 31a slightly towards the bolts 34, the forces become so great as to cause the bolts 34 to bend and either become sheared or pulled from the rotor 10.

Abstract: 542,693. Wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 17, 1940, No. 10492. Convention date, June 17, 1939. [Class 40 (v)] Two waves of the same frequency but differing in phase are modulated differentially in phase by the signal and are radiated from aerials giving different planes of polarization. Carrier from a source 10 is applied through a phase-retarding coil I, and a phase-advancing condenser J 1  to the respective grids of valve V 1 , V 2  the joint output of which feeds an aerial 36 through a line Y. The amplification of the valves is varied in opposite senses by applying the signal from source 40 differentially to the two grids, producing a phase-modulated wave in the aerial 36. Similar connexions are made through valves V 3 , V 4  and line Z to an aerial 38 arranged to give radiation of different polarization from that of aerial 36. The lines Y, Z are of different electrical length so that there is a phase difference between the currents in the aerials, and the phase modulation increases or decreases this phase difference according to the sense of the modulating voltage. At the receiver, the radiations are picked up by aerials responsive to the respective polarizations, and are combined vectorially to produce an amplitude-modulated wave which is detected by an ordinary receiver. The aerials at both stations may be dipoles set up at right-angles. Specifications 411,638 and 542,005 are referred to.
