Title: Multiplex signal-translating system
IPC: H04J3/16
Filed: 1941-08-29
Abstract: 550,814. Multiplex systems. HAZELTINE CORPORATION. Aug. 29, 1941, No. 11060. Convention date, May 28, 1940. [Class 40 (iv)] [Also in Group XL] In a system using cathoderay distributers, scanning takes place at a high speed under the control of a known circuit involving a valve 62 through which the horizontal scanning potentials are built up on a condenser 56 when the beam is traversing the targets connected to idle channels but is retarded when the beam is on the targets of operative channels. This is brought about with the aid of a second distributer tube 50 at the sending end controlled synchronously with the main tube 27 and having its targets energized from the signal channels through rectifiers such as 51 and limiters such as 52. When the beam of this second tube encounters a live target, it gives an impulse to an amplifier 78 which biasses the tube 62 in a direction to increase its impedance and so slow up the charging of the scanning condenser 56. If it is desired that the scanning cycle, when any channel is in use, should be more nearly of constant duration, the circuit shown within the rectangle 93 is provided. In this arrangement, a condenser 100, which is normally charged from battery 97 and determines the gain of amplifier 78, is partially discharged through a tube 95 each time the beam on tube 50 encounters a live target. The potential of the condenser and therefore the gain of amplifier 78 is thus progressively reduced and takes up a value which depends on the number of operative channels so that with a large number of channels the delay on'each target is small and vice versa.

Title: Course indicating devices
IPC: F41G7/24
Filed: 1973-03-09
Abstract: 1378431 Marine signalling apparatus MOBELL MARINE DEVELOPMENT CO Ltd 9 March 1973 [10 March 1972] 11225/72 Heading G4F [Also in Division H4] A course-indicating device includes a source of wave energy emitting a beam towards an object to be guided along a path and a mask which moves relative to the source and is so shaped that it intermittently blocks portions of the beam, whereby pulses are transmitted having first and second characteristic frequencies in first and second regions on either side of the path and varying widths depending on angular displacement to indicate the position of the object relative to the path. In a marine guidance system, a lamp 11 having a vertical filament 11a is mounted on a slide 13 (Fig. 2). A mask 17 is mounted to rotate about axis 15 when driven by a motor 50. The mask 17 (Fig. 1) has four shutters, 18, 19, 20, 24. The axis of the filament is arranged to lie on a line 14 which passes through gap 27 between the outer boundary of lobe 18 and the inner boundary 21 of shutter 20. Compound lens 29 is arranged to provide a virtual image of the filament 11a in the central portion and a divergent beam in the outer portion (Figs. 5-6, not shown). The beacon is sighted on to an approaching vessel via telescope 37 and motor 50 started. The mask rotates at two revs./see. If the vessel is on course, it receives uninterrupted white light through gap 27. If it drifts to the left, the light is interrupted by the shutter 20 and the indentations pulse the light at 4 p.p.s. Drifting further to the left, the light becomes interrupted by the shutter 24 and since the light is projected via filter 32, it shows red. If the vessel drifts towards the right, the lobes 18 pulse the light at 8 p.p.s. and a second filter 33 produces green light. In order to provide a constant beamwidth at the approaching vessel, its range is detected and lamp 11 moved manually or automatically accordingly, on slide 13. On the ship, the light may be detected visually or by photodetectors. In place of the visible light, use may be made of radio or acoustic waves, with suitable detectors on the vessel. For guidance of movement in a vertical direction, the device may be rotated through ninety degrees.

Title: Improvements in or relating to evaporating ion pumps
IPC: H01J41/16
Filed: 1959-04-03
Abstract: 901,468. Discharge apparatus. HERAEUS G.m.b.H., W. C. April 3, 1959 [May 30, 1958], No. 11421/59. Class 39 (1). A focused electron beam is used to evaporate the end of a wire of gettering material in an ion-getter pump. The pump shown comprises an electron-emitting filament 6 and a cylindrical wire-mesh electrode 5 which is maintained at a positive potential to drive gas ions into a layer of getter material which is deposited on the wall of the casing 3. An electron beam 10 from a filament 8 is focused at a point 11 by a solenoid 9. A wire 12, which may be a composite wire consisting of a wire or wires of one or more gettering materials such as titanium interwound with a support wire of tantalum, is fed through a tube 13 from a reel 16 by a feed device 14 operated by a driving device 15 which may be inside or, as shown, outside the casing 3. The getter wire enters the electron beam 10 at or near the point 11 on the side remote from the electrode system 5, 6 and at an angle α which is preferably less than 30 degrees so that the beam engages a significant length of the wire. Evaporation may be continuous or intermittent. In the latter case, during the intervals, the filament 8 is switched off or the heating reduced, and the getter wire is advanced to maintain the end near the point 11. The voltage applied to the electrode 5 may be switched off during evaporation periods to prevent a gas discharge between the electrode 5 and the casing 3 or filament 6.

Title: Improvements in or relating to resilient bearings
IPC: F16F1/38
Filed: 1946-04-15
Abstract: 610,955. Resilient mountings. SILENTBLOC, Ltd., and HUTTON, P. C. April 15, 1946, No. 11575. [Class 108 (iii)] In a resilient bearing of the kind comprising a bushing of resilient material interposed and radially compressed between inner and outer members, the resilient bushing has an outwardly-extending flange at each end and is formed in its undistorted state with a circumferential groove at the point where the part to be radially compressed adjoins the flange or each flange. In the mounting shown in Fig. 5, the bushing before assembly is formed as shown in Fig. 6 with flange portions G<SP>1</SP> having the same diameter and axial length as the flanges of the assembled mounting. A central portion G of greater diameter and less axial length than that of the corresponding portion of the assembled mounting, is bounded at each end by a radial slot G<SP>3</SP>, the diameter of the base of which is equal to the inner diameter of the outer rigid mounting member E (Fig. 5). On assembly, the bushing, Fig. 6, is forced into the outer member E until the inner edge of the rearmost flange G<SP>1</SP> abuts the respective flange El of the member E. The inner member B is then inserted in the bushing by means of a tapered leader member and the resultant elongation of the portion G causes the whole of the foremost flange G<SP>1</SP> to emerge from the other end of the member E. The member E is then mounted in a split-socket H of a mounted member such as a spring eye. In an alternative construction (Figs. 1 to 4, not shown), the mounting is split axially and each half is inserted from either end of a socket which is not of split form. In a further construction in which the socket is not split (Fig. 7, not shown), the mounting is similar to the construction of Fig. 5, but the member E is of greater radial thickness than that of the flanges G<SP>1</SP> and its outer diameter is uniform so that the assembled mounting may be pressed into a solid spring eye. A press tool for this operation bears on the annular space between the outer diameters of the flange and member E. The flange and compressed part of the bushing may be of the same external diameter before assembly. Specifications 527,780 and 689,321 are referred to.

Title: Improvements in and relating to radial flow fans
IPC: F04D29/52
Filed: 1952-05-08
Abstract: 698,935. Screw fans. BRITISH THOMSONHOUSTON CO., Ltd. May 8, 1952 [May 8, 1951], No. 11659/52. Class 110(i) A fan comprises a motor 7 mounted on a supporting base 1 and having a vertical shaft 10 on which are mounted impeller blades 11, 12; each impeller discharges a stream of air parallel to the shaft and towards the other impeller, the two streams meeting in the space between' the impeller and combining to form a radial discharge. Blades 11 draw in air through a guard member formed by rings 13 supported by struts 16 and 14, the latter being attached by bolts 15 to the base 1. Blades 12 draw in air through holes in a cover 29. The blades 12 (or alternatively the blades 11) are given a convex curvature. This imparts a radial component to the direction of the corresponding air stream, which facilitates the combination of the two streams with the minimum of turbulence. The air is discharged through louvres 19 which give an upward inclination to the direction of flow. A guide ring 18, the louvres 19, spaces 20, 21, 23, 24 and 25 and the cover 29 are attached to the struts 14 by means of bolts 22. Guard rings 26, 27 are held in recesses in the spaces 24, 25. Resilient feet 5, as of rubber, prevent transmission of vibration to the floor.
