Patent GB-2244456-A (GB)
Title: Correcting skewed print images
Inventor: KOBLER INGO
IPC: B41F13/08
Filed: 1991-04-24
Abstract: The position of sheets on sheet-conveying drums (4) disposed between impression cylinders (3) of an offset press is acted on by skew register adjusters (6, 7, 8). The same are connected to control facilities (11 - 13) which obtain their data from memories (14, 15) for the position of the partial images and from the immediately preceding control facility (11, 12). They act on register adjusters (5) controlling the peripheral and lateral register of plate cylinders (1). The sheet position from the immediately preceding printing unit is taken into account in the control facilities (11 - 13) for adjustment for the next printing unit. More particularly, a skewed position of a sheet arising from the previous printing is restored for the next printing in the light of the skewing necessary therein. The sheet position is automatically adapted to the requirements of each individual printing unit. Corrections of the peripheral and lateral register are also taken into consideration automatically. <IMAGE>

Very large indicia may be created by passing the boom over the ground in a raster-like pattern. The invention is described with respect to applying marking material (e.g. paint, dye) to sport-fields, parking lots, etc. but is not restricted thereto. The marking of vegetated areas by differential crop growth (either by differential sowing or by differential treatment of a single crop) is also envisaged. <IMAGE>

Title: Heating cabinet
Inventor: BINDER PETER MICHAEL
IPC: G01N25/00
Filed: 1992-05-19
Abstract: A heating cabinet includes a fan (24) by means of which air is drawn out of an inner housing into an air chamber (22). From the air chamber (22) the air is directed through a heating chamber (28) of U-shaped cross-section, containing a heating element (34), enclosing the inner housing, and is directed back into the usable space through apertures (36) in the side walls (16) of the inner housing. Air guidance plates (38) are attached externally on the side walls (16) which compel the air to flow along the entire length of the heating element (34) before it can pass out through the apertures (36). In this manner, temperature differences between the air passing through the different apertures (36) are avoided and localized temperature variations in the usable space are minimized. Heated air is directed across the inner surface of a door of the cabinet. <IMAGE>

Patent GB-2264202-A (GB)
Title: Clamping contact onto conductor
Inventor: GRAY IAN JAMES STAFFORD
IPC: H01R4/48
Filed: 1992-11-13
Abstract: A connector (e.g. coaxial connector) comprises a body with an axially extending bore therein for receiving a cable (e.g. coaxial) and for accommodating an electrically-conductive clamp (31) located adjacent the cable (not shown) and electrically coupled with a contact (e.g. pin contact (32)) of the connector. An axially displaceable clamp driver (35, 36) causes the clamp (31) to make good electrical contact with a conductor of the cable (e.g. central conductor of coaxial cable) in response to a predetermined axial displacement of the clamp driver (35, 36). The clamp driver (35, 36) has a first positive hold position (eg detent 39) relative to the connector body in which position the clamp driver (35, 36) acts solely to retain other connector components within the connector body. By the predetermined axial displacement of the clamp driver (35, 36) from the first positive hold position to a further positive hold position (eg detent 48) good electrical contact is established between the clamp (31) and the conductor of the cable, for example by radially inward movement of fingers of the clamp. <IMAGE>

Title: Parallel inverter system
Inventor: SHIRAHAMA HIDEFUMI
IPC: H02J9/06
Filed: 1993-02-15
Abstract: In a parallel inverter system such as for an uninterruptible power supply, output voltages of the inverters 2, 3 are compared at 25, 26 and a current control loop (11, 13, 17, 21,23; 12, 14, 18, 22, 24) responds to the magnitude of an output current of each inverter such as to change a command value for a voltage waveform control circuit 23; 24 associated with each inverter, and the gain of the current control loop is made to be variable, whereby currents shared by the inverters can be set to effectively suppress a cross current flowing between the inverters upon establishment of parallel running. In a further embodiment (Figs 6, 24) the output currents of the inverters are also compared to provide additional control. In an alternative embodiment (Figs 13, 14) the output voltage of one inverter may be compared with the average output voltage to the load. In a still further embodiment (Figs 15, 20, 21) the output currents of the inverters are compared instead of the output voltages. Further (Fig 26) the output currents of the inverters may be compared to the average output current. <IMAGE>

Patent GB-2272174-A (GB)
Title: Thermal sorting of particles
Inventor: ROSS VICTOR EMUL
IPC: B07B13/00
Filed: 1993-11-08
Abstract: A method of sorting particles, eg. diamonds and gangue, according to the thermal properties of the particles comprises, as a first step, subjecting the particles to one or more thermal treatment steps so that particles with different intrinsic thermal properties are brought to different temperatures. In the next step, conducted either during or after the thermal treatment steps, the particles are subjected to a further, non4hermal treatment. This treatment is chosen to give selected particles that are distinguished from other particles by a difference in temperature a certain feature which is not an intrinsic feature of the particles prior to the thermal treatment step. The particles can then be sorted into a fraction having the certain feature after a predetermined time period has elapsed since the further treatment step and a fraction not having the certain feature after that time lapse. In one form, the certain feature is a frosted appearance caused by the freezing of water vapour. In a second form, the certain feature is a frozen magnetic coating caused by a magnetite suspension, 18, Fig 1, located on a tank 16, or a magnetite suspension spray (108, Fig 2, not shown). In a third form, the certain feature is a frozen coating effecting buoyancy, and the particles are separated according to the rate at which they sink in a water stream 218, Fig 3, or whether they sink or float in said stream. <IMAGE>

Title: A door with an electromagnetic lock having a keep plate that is easily removed in an emergency
Inventor: SPENDIFF FREDERICK CHARLES
IPC: E05C19/16
Filed: 1993-12-22
Abstract: A floating keep plate 4 is mounted on a metal door 2 by a screw 16 which has a hexagonal recess 54 that may be engaged with a tool, after screw 52 has been removed from an access aperture 20, so as to release the keep plate 4 from the door frame 8. The releasing of the keep plate 4 in such a manner would be required if the keep plate 4 had been glued to its electromagnet by vandals. Head 58 of screw 52 is located in a cup member 60 which prevents access to the sides of the head thus making it difficult to unscrew the screw 52 and thereby preventing vandals gaining entry to the aperture 20. The keep plate 4 is electrically isolated from plate member 24 by rubber washers 32, 34 and plastics bushes 26 having metal pin members 28 which extend into recesses 30 in the keep plate 4. <IMAGE>
