Title: Apparatus for use in separating magnetic particles from a fluid  in which they are suspended
IPC: B03C1/034
Filed: 1972-10-23
Abstract: 1452271 Magnetic separation ENGLISH CLAYS LOVE RING POCHIN & CO Ltd 22 Oct 1973 [23 Oct 1972] 48811/72 Heading B2JApparatus for separating magnetic particles from a fluid comprises a chamber defined by a tube I provided with an inlet and an outlet for the fluid; a porous packing 3 constituted by a multiplicity of elongate ferromagnetic particles formed each with a plurality of fin-like or spine-like projections (Fig. 3, not shown) and arranged in the chamber; and an electromagnet 6 for establishing a magneic field in the region of the chamber occupied by the packing. An outlet tap 4 and a porous glass support 2 for the packing 3 may also be provided. The ferromagnetic particles may be produced by a milling operation on a block of corrosion-resistant ferrous alloy, e.g. stainless steel or iron of martensitic and/or ferritic form. In use, a non- homogeneous field with a very large number of points of high magnetic field concentration is established in the inter-particle spaces of the packing and the specification explains why this is particularly advantageous when the material to be separated from the fluid is only weakly magnetic. After use, the packing may be demagnetised, e.g. by an appropriately applied alternating magnetic field, and cleared of collected particles by flushing with water.

Title: Photographic camera with exposure control means
IPC: G03B7/12
Filed: 1962-12-28
Abstract: 1,027,598. Photographic cameras. EASTMAN KODAK CO. Dec. 28,1962 [Dec. 28, 1961], No. 48953/62. Heading G2A. A camera exposure control has racks 10, 12, 14, and 16 representing scene brightness, aperture, exposure time and film sensitivity respectively. The racks 10,12 engage a pinion 18, while racks 14,16 engage a pinion 20. The pinions 18 and 20 are mounted on a slide 26. The rack 10 is connected to camera actuating member 28 by a spring 30, the member 28 being urged upwardly by a spring 17. Downward movement of rack 10 is limited by an exposure meter having a pointer 32 cooperating with a stepped sensing member 36. An index mark 21 co-operates with a brightness scale 21. Downward movement of rack 10 causes counter-clockwise movement of pinion 18 and upward movement of aperture rack 12. A stud 40 separates blades 42, 44 upon downward movement of rack 12. Rack 14 has a cam follower 58 engaging a cam 60 integral with a speed setting dial 61. Rack 16 has a cam follower 68 co-operating with a cam 66 integral with a film sensitivity dial 76. In one mode of operation which maintains a preselected shutter speed set by setting dial 61 the operator sets a stop 54 to permit full aperture. Downward movement of member 28 first lowers rack 10 and raises rack 12 to increase the aperture, while racks 14 and 16 are maintained in their set positions by springs 56 and 70, and finally trips shutter trigger 33. A reduction in scene brightness allows further downward movement of rack 10, thus raising rack 12 further until maximum aperture is reached. Further movement of rack 10 causes pinion 18 to roll along rack 12, thus forcing member 26 to move down at half the speed of the rack 10. In other modes of operation lens aperture may be preselected by the operator or the operation of the exposure control may be set manually without reference to the automatic exposure control by disabling pointer 32. In a second embodiment, Fig. 2 (not shown) the aperture and film sensitivity racks 12 and 16 are transposed, while in a third embodiment a single rack 130, Fig. 3 (not shown) represents aperture and speed. In this embodiment a slide 120 is spring-urged downwardly into engagement with a cam 116. In a fourth embodiment Figs. 4-11 (not shown) slide 201 sets diaphragm vanes 210, while shutter speed is set by slide 213. A scene brightness slide 232 is arrested by a pointer 238 of a light meter 239. Film sensitivity is set by a cam 254 engaging a crank 251. Links 246 and 249, slides 201, 213 and 232 and crank 251, constitute a differential mechanism. High and low light signals "H" and "L" Fig. 12 (not shown) are visible in view finder lens 336 upon energization of lamps 318, 344 respectively. A third lamp 356 is aligned with a frame reticle reflected by mirror 324 to lens 336.

Title: Colour television cameras
IPC: H04N9/077
Filed: 1970-10-20
Abstract: 1322520 Colour television SONY CORP 20 Oct 1970 [21 Oct 1969] 49785/70 Heading H4F A colour television camera, Fig. 1 forms an image of an object 0 on the scanning surface 3 of a vidicon tube 1 or a solid state array image detector. A switch 9 operated in synchronism with the field scanning of the tube 1 switches on two xenon discharge lamps 6C, 6R alternately, each lamp being lit for a period of one field, the light from the lamps passing through a cyan filter 7C or a red filter 7R respectively, then to a halfsilvered mirror 5 and through a colour filter 4 and lens 8 to tube 1. The colour filter 4 is formed of a plurality of vertical red, green, and blue stripes in sequence. During the fields when the lamp 6R is lit the output from the tube 1 will be as shown in Fig. 3A, and in the other fields with the lamp 6C lit the output will be as shown in Fig. 3B. The output from the tube 1 is passed through a preamplifier 11 and shaping circuit 12 to a low-pass filter 13 and band-pass filter 14. The output from the low-pass filter 13 is the luminance signal which is passed to a matrix 15 and the chrominance signal from the band-pass filter 14 is passed to an adder 17 and subtractor 18 directly and via a delay circuit 16 of one field delay. At the adder circuit the bias signals from the lamps 6R, 6C, being of opposite phase cancel, and the output from the adder 17 is the chrominance signal which is fed to synchronous detector circuits 23, 24, 25. The chrominance signals of the object 0 cancel in the subtractor 18, the output of which is as shown in Figs. 3C and 3D in alternate fields. The output from the subtracter 18 is passed via a limiter amplifier 19 and phase inverter 21 to a switch 20 operated synchronously with switch 9 operating the lamps. Thus the output from switch 20 is of known phase and is passed to detector circuit 23 directly, to detector circuit 24 via a phase shifter circuit 22 and to detector circuit 25 via phase shifters 22, 26. The outputs from the synchronous detector circuits 23, 24, 25 which are the colour difference signals are passed to the matrix 15 from which the colour signals are obtained. In an alternative embodiment (Figs. 4-5, not shown) three lamps 6 with red, green and blue filters respectively are used. In this case two delay lines each of delay one field are used after the band-pass filter 14, the signals due to three successive fields being added to give the chrominance signal, and the signals due to two successive fields being subtracted from the third field to give the index signal. In this case instead of switch 20 and inverter 21 a three way switch and phase-shifters of 120 degrees and 240 degrees are used to ensure an index signal of known phase. The filter 4 may have red, green and cyan stripes, and the lights 6 may be switched on successively for a period of one scan line, the delay lines then each having a delay of one line.

Abstract: 1479271 Article vending apparatus M KRAKAUER 8 Dec 1975 50261/75 Heading A4T An article vending apparatus comprises a cabinet (2) having a plurality of vertically arranged shelves (10), Fig. 1 (not shown), each shelf 10 being divided into a plurality of storage compartments 12 by vertical partitions 13 and each compartment 12, in use, having a plurality of articles 6 located therein and which are discharged therefrom by means of pushers 28 located to the rear of each article, each pusher 28 having a hook-shaped head 30 which is releasably located in a clearance 38 between two convolutions of a helical flange 26 which is mounted on a rotatable rod 23, the latter being connected to a drive motor 25. There is a rod 23 and motor 25 associated with each compartment and when coins are inserted in a slot (9) and the appropriate actuating button (7) pressed, the thus selected motor 25 is energized to cause rotation of the associated rod 23, whereby the pushers 28 of the selected compartment 12, due to their engagement with the helical flange 26, are caused to move towards the forward edge 11 of the shelf 10 and the forwardmost article on the shelf is pushed by the pusher 28 immediately behind it past the edge 11 to be discharged through an opening (8) in the cabinet (2). Each pusher 28, after it has pushed the article in front of it off the shelf 10, actuates an electric switch (41), Fig. 4 (not shown), to stop the motor 25 so that the pusher 28 then assumes a position immediately above the shelf edge 11 as shown in Fig. 3. When the pushers 28 are again advanced that pusher 28 is pushed by the article behind it off the shelf 10 and pivots about the rod 23 to a vertical orientation in a pusher storage area 22. As the pushers 28 are releasably mounted on the rod 23 they can be put back into position between the articles on shelf 10 when re-loading with articles. The pushers 28 are maintained above the shelf 10 in a horizontal orientation while moving relative thereto due to the engagement of the pusher heads 30 with an inclined support plate 39 which terminates at an edge 40. The pushers 28 also extend through a slot (17), Fig. 5A(not shown), formed in a partition wall 14 of the associated compartment 12.

Abstract: 1,108,356. Controlled non-linear inductors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 7 Jan., 1965 [20 Dec., 1963], No. 50379/63. Heading H3B. [Also in Division H2] An arrangement for detecting alternating current flow, e.g. an earth leakage current, comprises a transformer T1 having a core whose degree of saturation depends on the current to be detected flowing through a first primary winding C 1 , C 2 , a second primary winding A 1 , A 2 , energized by A.C. of a frequency higher than that of the current to be detected, a secondary winding inductively coupled to both primary windings and connected to energize a relay RL when the flux produced by the first primary winding does not saturate the core sufficiently to reduce the inductive coupling between the second primary winding and the secondary winding. The normal higher frequency output of the secondary winding maintains the relay operated until earth leakage occurs when the relay drops out to effect the operation of signalling or control means. The secondary winding may be connected to the relay through a transistorized amplifier 3, a Zener diode 4, an auxiliary transformer T2 and a bridge rectifier 5.

The spacer 4 shown has one stud 21 for attachment to the plate 1 and a fixing stud 25 on its other edge, between centring ledges 30. Since it cannot be guaranteed that the spacer will be truly perpendicular to the plate, the bridge is provided with a hole 29 larger than the stud 25 but smaller than the outline of the ledges. Spacer 3 is similarly provided with two studs 16, each having centring ledges. The plate and bridge are aligned during assembly by guide rods located in apertures 12-14 in the plate and corresponding recesses in the bridge, and the latter is then pressed on to the spacers so that the ledges bite into the peripheries of the holes 29 in the bridge. The bridge is retained by riveting the studs 16, 25. A notch 23 and hole 24 in the spacer 4 respectively support a balance cock and a winding stem (not shown). Two spacers may be held at right angles to each other by a notch arrangement, Figs. 8, 9 (not shown). A number of detachable fixings of the bridge to the spacers are described, e.g. using screws or wedges - see Division E2;

Abstract: 1466609 Vehicle occupant restraint bags GENERAL MOTORS CORP 28 Nov 1974 [21 Dec 1973] 51570/74 Heading B7B A bag inflator is actuated by switches built into the vehicle's shock absorbers in such a way that the bag inflates when a roll-over condition occurs. As illustrated, each shock absorber 10 includes a switch 22 which is normally open, but is closed by a projection 26 if the shock absorber becomes fully extended. A further switch 32 is normally closed, but is opened by a projection 36 if the shock absorber extends beyond its normal operating range. The switches of the vehicle's four shock absorbers are arranged as shown in Fig. 4. Thus, inflation occurs if the shock absorbers at one side of the vehicle are fully extended while the shock absorbers at the other side of the vehicle remain in their normal operating condition. In another embodiment, Figs. 1 and 2 (not shown), the switches 32 are omitted so that inflation occurs if the shock absorbers at either one or both sides of the vehicle are fully extended. With either arrangement, the inflator is de-energized by switching off the ignition so that jacking the vehicle up does not cause inflation.
