Title: Video standards and aspect ratio conversion
Inventor: RICHARDS JOHN WILLIAM
IPC: H04N7/01
Filed: 1992-02-17
Abstract: A digital video signal is real-time converted from a high definition format (such as 1250 lines, 50 field/s, 2:1 interface, with a 16:9 aspect ratio) to a conventional definition format (such as 525 lines, 60 field/s, 2:1 interlace, with a 4:3 aspect ratio) by compressing the image so that the active area extends across only part of an intermediate field/frame; by writing the pixels of the high definition fields to alternate field stores at the high definition format pixel rate; and by forming the output frames in the conventional definition format by reading, at the conventional definition pixel rate, pixels of at least part of the active portion from the field store which is not being written. Alternatively, a conventional definition format signal is converted to a high definition format by placing each conventional definition field in a portion of a high definition field and then expanding that portion substantially to fill the high definition field. In order to deal with a change in field rate between the input and output video, a standards converter (64) is included in the high definition part of the arrangement. <IMAGE>

Title: Syringe with disconnectable plunger incorporating needle detaching and housing means
Inventor: VAN DER MERWE MARIUS
IPC: A61M5/32
Filed: 1992-04-07
Abstract: A syringe has a piston member 10 which slides in a piston bore 1. The piston member is driven into the bore using a plunger 11, so as to discharge a substance in the syringe through a needle 5. The plunger is connected to the piston member by a one use connection 14 which breaks when the syringe has been completely discharged or if an attempt is made to reuse the syringe. The plunger also provides a receptacle 20 for receiving and containing the syringe needle when this has been detached from the syringe end, after use. <IMAGE>

Title: Tank furnace for low pressure injection casting
Inventor: BORTOLONI ANDREA
IPC: F27D99/00
Filed: 1992-09-02
Abstract: In a tank furnace (F) for low pressure injection casting, one or more heating element loops (R) that maintain the metal at a temperature higher than the solidification temperature extend round the interior of the furnace, just above the maximum level of the molten metal. This allows the furnace (F) to be compact, makes efficient use of the energy radiated by the heating element loops (R) and permits an injection duct (I) to be of short length, thereby reducing the likelihood of bubbles forming in or metal cooling too much in the injection duct (I). <IMAGE>

Title: Workpiece loading and unloading method and device for a plate processing machine
Inventor: ITO MASAOKI
IPC: B23Q7/04
Filed: 1993-02-26
Abstract: A material pallet moves reciprocally between a loading/unloading station ST-0 at one side of a plate processing machine 1 e.g. a turret punch, and a station ST-1 flanking station ST-0. With the material pallet at station ST-0 a workpiece W is separated from those carried by the pallet and is loaded into the machine by a transfer device 43. The material pallet is transferred, from station ST-0 and a product pallet is transferred to ST-0 during processing of workpiece W. The finished product is then transferred to the product pallet at station ST-0 by the transfer device 43. Pallet storage shelves (29, Fig. 3) are located in ST-0 above the transfer device 43 and an elevator (77), including means for feeding pallets laterally is movable vertically in ST-1 to transfer pallets between the shelves and the transfer device. The transfer device incorporates a device locating a workpiece at a home-position in the processing machine. An alternative transfer device includes a home-positioning device movable in X- and Y-axis directions and pivotable in the horizontal plane, and a workpiece clamp pivotable so that it can clamp an inclined workpiece edge without bending it. <IMAGE>

Title: Latching telescopic handle for baggage cart
Inventor: CHANG FU JUNG
IPC: B62B1/12
Filed: 1993-08-05
Abstract: A handle assembly for a baggage cart comprises a handle member 33 attached to the top end of an inner tube 30, the latter sliding within an outer tube 20. Outer tube 20 has a number of locking holes 21 for receiving balls 56. Fixed to the lower end of the inner tube 30 is a sleeve 40 having holes 42 into which the balls can retreat. Within the sleeve is a plunger 50 with a circumferential bevel. The plunger is connected by link 60 to an operating member 10 below the handle, and is spring loaded downwardly. Upward force on the member 10 lifts the plunger and allows the balls to retreat into the sleeve, thus allowing telescoping movement. Release of the member 10 causes the bevel of the plunger to push the balls into the next available hole 21. <IMAGE>

Title: Flexible doors
Inventor: MANSLEY DAVID LESLIE
IPC: E06B9/13
Filed: 1995-01-05
Abstract: Door panels 10, 11 each comprise a pair of spaced flexible members (15, 16, Fig.2) which are wound onto and pulled of drums by an operating motor 33 in order to open and close the door panels 10, 11. If power to the operating motor 33 fails then a drive sprocket 54 may be disconnected from a gearbox 53 so that the flexible members may be wound onto the drums to at least partially open the door panels 10, 11. The force of winding the flexible members may be provided by a spring force within the drums causing rotation of the drums or from a weight falling downwardly or manually by pushing the door panels 10, 11 apart. The method of disconnecting the drive sprocket from the gearbox may also comprise a weight falling downwardly which operates a lever to disconnect a clutch mechanism. <IMAGE>

Title: Protection against lightning surges on power lines
Inventor: GUMLEY JOHN RICHARD
IPC: H02H9/00
Filed: 1994-05-13
Abstract: An arrangement for protecting electrical equipment from the effects of lightning strike-induced surges on power lines is provided in which a protective device (10; 12; 20 or 30) is connected across the inductor (L) of an L/C filter, the device being arranged to remain inactive and present a high impedance to an electrical impulse or transient applied to the filter and to shore circuit the inductor (L) when a voltage polarity reversal on the inductor (L) occurs upon completion of the impulse or transient, so that magnetic energy stored in the inductor (L) during the impulse or transient is subsequently dissipated in the form of heat instead of being passed forward to the protected equipment. The device may comprise or include a bridge rectifier arrangement (12 or 20) either with the inductor (L) located within the rectifier bridge (12) or with a switching device (18) located within the bridge (20) to be triggered by a voltage reversal sensing device (16). Alternatively, the device (10; 30) may include an arrestor (14; 31) and at least one capacitor (C1, C2; 38, 39) adapted to be charged as a result of the transient applied to the filter, and the voltage in the capacitor is added to the post-transient voltage in the inductor (L) of the filter so that the combined voltage causes the arrestor (14; 31) to operate. <IMAGE>

Title: Vacuum Electron Tube Having A Getter
Inventor: RICAUD JEAN-LUC
IPC: H01J29/94
Filed: 1995-03-14
Abstract: A vacuum tube, particularly a cathode ray display tube, is disclosed. To absorb residual gases once a vacuum has been formed within the tube, a getter material (barium) is evaporated onto the inner tube walls from a getter holder. Instead of being welded to the electron gun (14), the getter holder (40) is separate from the gun and rigidly connected to the walls of the tube neck (12) in front of the electron gun. The distribution of the getter material throughout the tube is thereby improved, especially in the case of neck-focusing tubes, i.e. tubes in which the (graphite-coated) inner neck wall acts as a cylindrical electron beam focusing electrode at anode potential. <IMAGE>
