Title: Plywood panels with uniform moisture content - are produced by drying individual laminations before gluing them together
IPC: B27M3/00
Filed: 1990-08-21
Abstract: The plywood panels consisting of at least two layers of wood laminations  are produced from squared timber in the following way. A blade is pressed on the timber, which is supported on the side opposite to the blade, to remove a thin layer of wood from the timber. This process is repeated until all the timber has been cut into laminations. The laminations are then dried in a drying chamber for a period of at least six hours before being glued together to form the plywood. Drying the wood after it has been cut to form laminations ensures that the plywood panel has a uniform moisture content of less than 15 percent by weight. USE - Plywood mfr.

Title: Uniform distribution of ATM cells to group of lines -  selecting line for each cell with lowest preceded load
Inventor: WAHL STEFAN DIPL ING
IPC: H04L12/54
Filed: 1990-09-13
Abstract: For each ATM cell that line is selected which has been least loaded by a preceding cell. Pref. with lines with allocated buffer memories, where content has been detected, and with lines of one group, these lines are selected whose buffer memory shows the lowest content. From two concerned lines, the one which has been left out during the last selection is selected. Groups of more than two lines may be divided into two subgroups with approx identical number of lines, and each subgroup with more than two lines may be again subdivided. Of two subgroups concerned the one omitted during previous selection may be selected. ADVANTAGE - Improved grouping and selection based on outgoing traffic.
Patent DE-4030619-A1 (DE)
Inventor: AUINGER HERBERT DIPL ING DR TE
IPC: H02K1/27
Filed: 1990-09-27
Abstract: The invention concerns a multi-phase permanent-magnet-excited synchronous electric motor with a stator winding powered via a current converter in such a way that, besides the magnetic flux (OM) generated by the permanent magnets, an additional flux component (reluctance flux OR) is generated by the current-conveying armature winding, so that the armature winding is interlinked with the vectorial sum of two flux components (OM and OR), in which motor the rotor has at least one section (M) fitted with permanent magnets and at least one section (R) of soft magnetic material. The efficiency and/or power of such a motor can be improved if the sections (M, R) are arranged in such a way that there is a common flux path for the magnetic flux (OM) of the permanent magnets and the additional flux component (reluctance flux OR) in the motor's stator and/or the sections (M, R) have their magnetic axes (d1, d2) mutually angularly displaced in the circumferential direction.

Title: Detecting conductor lead(s) e.g. in wall - applying HF carrier LF modulated at accessible end of test lead for detection b radio receiver
Inventor: ACHATZ DIETER
IPC: G01V3/12
Filed: 1990-09-27
Abstract: A radio transmitter (1) is applied to an accessible end of a test lead (3) whose course is hidden to introduce an l.f. modulated h.f. carrier. A radio receiver (5) is applied to locate the max. radiation of the carrier frequency (12) from the lead. This procedure is carried out by a test probe (6) with a movable lead serving as a receiving aerial for the receiver. This probe is moved along the path where it is assumed the lead runs as long as audio (7) and visual (11) indicators display the max. of the carrier frequency. In other words, the probe is moved so that the max. is always displayed. The visual can be a LED and the audio a loudspeaker. ADVANTAGE - Rapid location for single lead or one within a bundle even if live. Requires no return lead.

Abstract: A laundry drier has a heat exchanger block which serves as a condenser and is e.g. designed as a tube block and consists of versatile modular constructional units which together form a compact constructional unit which in turn can be positioned in a versatile manner and easily removably in the laundry drier. The compact constructional unit is for example inserted into the door, and on guiding through and cooling of the warm air conducted over the moist laundry the steam contained therein is condensed into water. The condenser is designed as a tube condenser and consists of plastic parts interconnected by insertion connections. In a preferred embodiment, the condenser consists of a flat, sleeve-shaped housing (15), the open sides of which are closed by a headpiece and a footpiece (20, 21), between which the tubes are arranged. This unit is mounted as a whole e.g. floating in the door. The laundry drier is formed particularly advantageously from the point of view of manufacturing technology and can be used in and removed from different drier types as a modular constructional unit in an advantageous and service-friendly manner. <IMAGE>

Title: Evaluating structural changes of homogeneous materials under road - applying changing forces and measuring resulting force levels and differences, esp. for biological tissue
Inventor: SCHNEIDER MANFRED PROF DR
IPC: G01N15/14
Filed: 1990-11-30
Abstract: A method for evaluating structural changes of inhomogeneous materials involves subjecting the specimen under test to a force whereby the type of force application and variation are determined by the user. Force levels and differences are measured electronically and the resulting structural variations displayed visually, subjected to image analysis and evaluated.

Title: Spinning frame - has test equipment installed to determine that the cheese being produced and wound is of satisfactory solidity
Inventor: STAHLECKER FRITZ
IPC: B65H54/02
Filed: 1991-03-28
Abstract: A process to supervise a unit on a spinning frame which produces a cross wound cheese. At a specific moment of prodn., the degree of solidity of the cheese is tested, and if the measure of the solidity differs from standard, the cheese is identified, or rejected. The appts. is also claimed. The service robot passes along the front of the frame and stops for various purposes at regular intervals. Tests can be made at the same time, with particular attention to cleaning, as a soft wind is often the result of dirt, fluff and lint interference in the machine. Included in the equipment on the robot are two feeler blades (27,28), one of which (37) is wide, and the other (36) narrow. The tension exerted on the axle (35) through the base of the blades, forces the boss (33,34) to press the blades against the cheese (20). Devices are employed to make a comparison between the depression of each feeler blade. ADVANTAGE - The cheese may have developed softness by being disadvantageously wound during a disturbance in the process, and may be withdrawn for further attention.
