Patent DE-4201905-A1 (DE)
Title: Drying wet material, esp. sludge - using twin roll dryer with heated rolls
Inventor: GAIL JOSEF
IPC: F26B17/28
Filed: 1992-01-24
Abstract: The use of a twin roll dryer with heater rolls (11,12) for drying wet material (16) is claimed, where: (a) wet material (16), with a dry solids content of 15-50 (pref. 25-35) wt. %, is fed from above into the gap (10) formed between the two axially parallel, counter-rotating, cylindrical rolls (11,12); (b) the rolls (11,12) are pressed together to form a 100-300 (pref. 150-200) microns thick dry residue layer which is stripped from the rolls by scrapers (21) downstream of the gap (10); and (c) the distance between the gap (10) and the scrapers (21) the peripheral roll speed and the roll temp are adjusted so that, at the locations of the scrapers (21), the dry residue has a dry solids content of 70-90 (pref. 75-85) wt. %. A twin roll dryer for use in the process is also claimed. The rolls (11,12) are pref. inclined at about 45 deg. to the horizontal and have a surface temp. of 80-120 (pref. 90-110) deg. C The scrapers (21) are pref. spaced by an angular distance of at least 270 (pref. at least 300) deg. from the roll gap (10). The wt material (16) is fed onto the top of the roll gap over (part of) the length of the rolls (11,12) pref. by a distributor device (17) of shape matching the gap inlet profile. USE/ADVANTAGE - The dryer is used esp. for drying sludges, eg., clarification sludges from municipal waste water treatment and sludges from electrolytic treatment processes. It allows drying of wet material with high liq. content in a single stage with low equipment costs and a good energy balance.

Title: Cine-camera positive film transport drive with differential spool speed control - has separate motors for film run-off and take-up with speed sensors for ensuring constant film tension and transit speed
Inventor: GRATZL RUDOLF
IPC: G03B1/12
Filed: 1992-02-20
Abstract: A film transport mechanism comprises a magazine unit (1) with film run-off (3) and take-up (6) spools each having a belt drive (4, 7) to individual plug-in half-couplings (51,81). A drive unit (2) with powerpack (13), controller (14) and separate motors for film run-off (9) and take-up (11) has belt drives (10,12) to the corresponding half-couplings (52,82). The two units (1, 2) connect (5, 8) together via the couplings (51,52,81,82) and the controller responds to the differing spool speed requirements as a result of speed-sensor (15,16) signals to regulate the motor (9,11) currents and their rpm such that a constant film tension and transit speed results. ADVANTAGE - Does not rely on frictional slip for spool spaced regulation. Can be matched to any camera speed and film reversal is readily achieved by turning magazine through 180 deg. so that run-off and take-up functions are interchanged.

Title: Calibrated longitudinally pumped solid state laser system - has several crystals with pump diodes arranged to provide spatial overlap and different wavelengths
Inventor: DURKIN PETER
IPC: H01S3/0941
Filed: 1992-04-18
Abstract: The laser system is pumped by a number of semiconductor laser diodes (21-27). Laser crystals (31-37) are optically pumped at several predetermined positions along its length or around its circumference. The crystals (31-37) form a resonator. In the crystals (31-37), the incoming and outgoing modes are at a small angle to each other. A laser geometry is formed from a predetermined number of small pieces of crystal material (31-37). Each of these small crystals has an associated pump diode (21-27) for longitudinal pumping with good spatial overlap. The small crystals (31-37) reflect respective wavelengths at their pump light sides (31a-37a) but not at their opposite sides (31b-37b). The mode emitted from one crystal is refracted at such an angle that it enters the adjacent crystal. ADVANTAGE - Provides high output power and also guarantees generation of different laser wavelengths.

Title: Drinks packaging made of a paperboard/foil combination
Inventor: WILLEMS MANFRED
IPC: B65D75/58
Filed: 1993-02-04
Abstract: The drinks cartons commercially available to date have the problem, during disposal, that the different materials (paperboard/foil) can be separated only with difficulty or not at all. This problem is solved here in that two containers are involved. On the outside, paperboard for the necessary stability and inside a foil bag for the sealing. After the container has been emptied, the foil bag is taken out of the paperboard container again and both (paperboard and foil) are separately disposed of or recycled. At the top of the foil bag there is a tip. The latter is placed, upon closure of the paperboard container, such that after opening the opening tab on the paperboard carton it can be pulled out, cut off and then used as a spout.

Title: Electric vehicle motor control - using on-board computer with stored selectable travel patterns and motor controlled by signal indicating required position change.
Inventor: TAKAMOTO YUUSUKE
IPC: B60L3/00
Filed: 1993-03-19
Abstract: The method of controlling an electric vehicle motor involves operating the motor in response to a speed/torque signal from a vehicle driver. When the vehicle stops, this state is determined and a position control signal is generated. Another position control signal is generated corresp. to the required (ie another) stop position, chosen by the driver. The motor is then operated accordingly. The vehicle has a computer memory storing a variety of travel patterns, which are used to control the motor torque during the travel sequences. A particular pattern can be chosen by the driver. When the vehicle comes to a halt on a slope, the motor torque is controlled so that the vehicle remains stationary. ADVANTAGE - Vehicle is automatically held stationary at each desired stop position without further driver action.
