Title: Torque distribution controller for rear-wheel-drive vehicle - operates on clutches transmitting torque to respective wheels with suitable differential rotational speed for curve negotiation
Inventor: NIIKURA YASUHIRO
IPC: F16H48/26
Filed: 1991-11-19
Abstract: Drive is transmitted to the two rear wheels (6R,6L) through separate half shafts (8R,8L) from clutches (7R,7L) with stepping motors (30R,30L). The relative torque is adjusted by a clutch control unit (40) responsive to signals from a steering direction detector (41) and a calculator of necessary differential rotational speed from the measured road speed and radius of curvature. The outer wheel is driven at max. torque for a given differential speed, at which the clutch for the inner wheel is slipped to give the appropriate transmission characteristic. ADVANTAGE - Road-holding improved with stable behaviour on curves at higher speeds.

Title: CRT disposal process - separates tubes into sections for coating removal and division into glass types and metal components for recycling
Inventor: BRANDENBURG GUNHILD
IPC: C03C1/00
Filed: 1992-02-20
Abstract: To recycle cathode ray tubes, the ventilated tubes are separated about 1 cm below the upper end of the upper section, between the lower and centre section and between the centre and upper secions. The coating is removed from the lower and centre sections. The glass material is sepd. by types, and passed to recycling, and the sepd. metal components are transferred to recycling. Where two different glass types are against each other, the sepn. point is selected where they are bonded together or 5 mm from the glass bonding point in two cuts, to remove the whole glass bonding area. Where the glass of the lower and centre sections are of the same type, the sepn. is where the stronger glass of the lower section changes to the weaker glass of the centre section. The removal of coating from the lower section is by dry suction after it has been lightly detached mechanically by scraping. The remainder of the coating is removed by rinsing, or it is removed in a single operation by high pressure rinsing with a fluid containing fine grinding material. The coating from the centre section is removed in a single operation with acid or high pressure rinsing with a fluid contg. fine grinding matter. USE/ADVANTAGE - For the disposal of CRTs of various types, and for the recycling of the component materials. The operation recovers the usable materials in a cost-effective system to process a large volume of CRT

Title: Selection of timber offcuts during transport by conveyor in sawmill - scanning laser beam marker over moving timber both along and across conveyed direction and identifying w.r.t. edge of viewing zone
Inventor: SOEDERHOLM SOEREN
IPC: G06K7/10
Filed: 1992-12-30
Abstract: The method of selecting and marking the position (12) of an offcut whilst being conveyed for sawing (in the direction R) employs a laser light source (21) and universally mounted mirror (20) above the conveyor (11) which scans a known length (11a) of conveyor track.

The offcut position (12) is identified w.r.t. its partic. length (10b) via the pulse transmitter (16) and its transverse position is operator indexed by a keyboard (23). The positional data together with other keyed-in instructions is signalled (S) to the saw by the controller (15). USE/ADVANTAGE - For removing defective root end of timber lengths. Enables operator to inspect timber lengths in any order and allocate longer inspection times to lengths which pose more difficult decisions without need to alter conveyor speed.

Title: Colour value calibration - uses conversion table for scanned values to be corrected into valves for colour separation appts. for printing plates
Inventor: BESTMANN GUENTER
IPC: G03F3/08
Filed: 1993-02-25
Abstract: To calibrate values on conversion from a colour range into a second colour range, for appts. and systems, a conversion table is calculated, and stored from the colour values (R,G,B) for the colour range of the functional values ( L star j (s), a star j (s)) of the colour range associated with the input unit (1,2,3) with allowance for the spectral and electrical characteristics of the input (1,2,3). For the colour values of the original range, a number (j) of defined test colours in a test piece are scanned opto-electronically (1,2,3) using a test piece with the same material characteristics as the original to be scanned. The functional values are compared with exactly measured values (L star m (s), a star m (s), b star m (s)) of matching test colours for a given lighting, with colorimetric measurement. From the comparison, colour difference correction colour values are calculated (delta L star rgb, delta a star (rgb(s), delta b star (rgb (s)) for the stored values in the conversion table. Also claimed is an appts. with an interpolator as a correction unit with a second table memory for the corrected colour values (L star kor, a star kor, b star kor). USE/ADVANTAGE - The technique is for the calculation of colour values as an original, for conversion to the appts. to give the colour separations for the printing plates.

Title: Diesel engine EM actuated fuel metering valve controller - has current sensor feeding back information to controller to determine on and off switching points of valve
Inventor: LOCHER JOHANNES ING GRAD
IPC: F02D41/40
Filed: 1993-03-19
Abstract: The valve is used for precise metering control of fuel supplied to a diesel engine. A fuel management controller (100) provides a control signal to operate a FET device to activate a metering valve. This moves a needle to open or close a flow orifice. The current applied to the actuator is monitored and fed back to the controller to allow the switching points of the valve to be accurately determined. The current cycle is determined by the applied voltage pulse. At a specific point a transition occurs to initiate the time point at which the max. valve opening occurs. A similar interpretation of the current cycle allows the closing time to be determined. USE/ADVANTAGE - Simplified operating point determination. Fewer components required.
