Title: Dry=sump lubrication system for four=stroke engine
Inventor: AIZAWA SHIGEMITSU
IPC: F02B75/02
Filed: 1995-11-29
Abstract: The oil is stored in a tank (36) with connecting passage (38) to the crankcase (9). Oil in liquid form is directed onto the working parts in the crankcase and mixed with gas flowing through the latter, forming fine particles.The particles are discharged from the chamber to avoid oil accumulating there, and delivered via an engine piston (17) to a combustion chamber (200) or returned to the tank by the pressure generated by the reciprocating piston. Delivery to the crankcase from the tank can be by pump (39), while there is an opening (39) in the passage connected to the crankcase and which is situated above the level of the working parts.

Patent DE-19547257-A1 (DE)
Title: Balancing strut for flap member
Inventor: KUESPERT MAX
IPC: F16F7/09
Filed: 1995-12-06
Abstract: The strut may be of variable length between two opposed end points and comprises two operatively interconnected yoke members (15,15a) that are formed by loops that are elongate in the longitudinal direction of the strut. Each loop of each yoke is turned through 90 deg relative to the loop of the other yoke member. The loops cooperate to bound a cavity between the yoke members. The yokes are then relatively displaceable in the longitudinal direction of the strut but secure against relative rotation. A tension spring (20) closely surrounds the yoke members. A damping element (19) may be arranged in the cavity.
Patent DE-19547283-A1 (DE)
Title: Encoding system for use in providing e.g. identification code in different access systems without keys e.g. in motor vehicle
Inventor: FURUTA NORITOSHI
IPC: B60R25/01
Filed: 1995-12-18
Abstract: The system has a transmitter (1) which transmits a characterising code to an object which uses a key free access system. The transmitter (1) has a memory (11) which stores the characterising code. A first arithmetic unit or microprocessor (12) encodes the characterising code output from the memory (11). A transmission unit (13) transmits an encoded characterising code generated by the arithmetic unit (12).The first arithmetic unit (12) divides both the characterising code and also a corresponding roll code into a number of blocks. The roll code varies its contents in response to each transmission of the characterising code through the transmission unit (13). The roll code determines a repetition number for an arithmetic encoding operation and repeats the encoding operation in each block according to the repetition number to encode the characterising code. A second microprocessor (21) decodes the encoded code by carrying out the operation of the first microprocessor in reverse.

Title: Motor vehicle lamp control arrangement for measurements with given type of light
Inventor: FLEISCHER JOHANNES DR ING
IPC: G05D25/02
Filed: 1995-12-29
Abstract: The light received for measuring emissions is produced by a regulated filament lamp (1) and its beam path to the measuring area (2). In the beam path is a semitransparent mirror (3), deflecting some of the light through a red filter (4) and a blue filter (6) to photo-elements (7,9) and these two colours can be varied. The beams from the two elements pass through the amplifiers (10,11) to a quotient shaper (12), giving the red/blue ratio. The ratio signal controls a power amplifier (13) supplying the voltage to the lamp. The process is regulated by the unit (14) on the basis of the required value (Uv) for a given red/blue ratio.

Title: Image data compression method for video images
Inventor: KLOSE HELMUT DR ING
IPC: H04N19/85
Filed: 1996-04-19
Abstract: Image data representing an image sequence is compressed, the image sequence being obtained from a video camera. The data are compressed taking into account the camera position and/or changes in the camera position while the image sequence is being recorded.  Fourier transformation, frame coding or chrominance coding are used to compress the data. The compression also takes into account the translational and rotational movement of the video camera which are detected by a movement sensor. The zoom factor is also taken into account.

Inventor: BART HANS-JOERG DR
IPC: F16H15/38
Filed: 1996-07-19
Abstract: The invention concerns a toroidal drive which can be operated in two performance ranges. The input shaft (2) of the gear is connected to an intermediate shaft (5) via a first transformation stage (wheels (3) and (4)). From the intermediate shaft a continuously variable transmission (CVT) is driven via a further transformation stage (wheels (6) and (7), drive chain (9)). A further transformation stage (21) is connected downstream of the CVT. The input power is either fed directly to a summarizing gear set (24) or - with the power being branched - is introduced into the summarizing gear set (24) via a further transformation stage (wheels (29) and (30)). The total of three transformation stages present enable the ratios between the speeds of rotation within the CVT to be optimized. Preferably the drive is suitable for use in a vehicle in whose drive train the engine, transmission and output are disposed in a line.

Patent DE-19636067-A1 (DE)
Title: Filtering of plastic melt and filtering equipment for reducing flow variation
Inventor: HOBRECHT KNUT
IPC: B29C48/694
Filed: 1996-09-05
Abstract: In a process for continuous filtration of plastic melt the main melt flow is divided into separate streams each of which flows through a filter chamber(3.1,3.2) with filter and is then recombined. When a filter requires cleaning the flow through that chamber(3.1,3.2) is diverted through an intermediate filter(5). Process equipment comprises a filter unit having parallel filter chambers with filters each connected to a melt feed and take-off. An intermediate filter(5) parallel to the filter chambers(3.1,3.2) is synchronously connected to the melt feed(1) and take-off(13) when one of the filter chambers(3.1,3.2) is shut-off. In a process variation the melt flows into a filter chamber containing a cylindrical filter closed at one end and flows from the outside to the inside of the filter to reach an outlet from the filter chamber. The melt flow is divided into two streams, the first entering the filter chamber at the outlet end of the filter and the second stream entering at the opposite end. A filter unit for the process variation includes a filter chamber with melt inlets entering at the open end of the cylindrical filter and another inlet entering at the closed end. The design ensures uniform melt flow over the whole filtering area.

Patent DE-19708965-A1 (DE)
Inventor: ZETTLER THOMAS DR
IPC: G06F11/20
Filed: 1997-03-05
Abstract: The invention relates to a memory characterized in that it comprises at least one memory cell array containing memory cells, a redundancy circuit containing at least one redundancy memory cell, and a redundancy-selecting line selector circuit having at least one allocation memory in which allocation information can be stored, whereby on the basis of said allocation information at least one redundancy memory cell can be assigned to at least one memory cell. In addition, the allocation memory has an allocation memory cell with an intermediate memory for storing the allocation information. Depending on the programming method used, known memories require relatively long programming periods for assigning redundancy memory cells to memory cells. In the case of the memories provided for by the invention, the allocation information can be transferred from the intermediate memory to the allocation memory cell, thus making it possible for redundancy memory cells to be assigned to defective memory cells rapidly and in an energy-efficient manner.

Title: Single stage veneer applying denture press process e.g.for metal dentures
Inventor: SCHREIBER HANS DR DR
IPC: A61C13/38
Filed: 1997-03-12
Abstract: In the fabrication of dentures an outer veneer is applied to the denture by a press. The novelty is that: (a) the press applies a veneer to the denture by the application of heat and pressure to a suitable plasticised veneer mass; (b) the dental form is first filled with wax or similar and pre-heated; (c) the dental esp. metal cast frame is then pushed into the form, expelling the wax mass but retaining a residual wax coating; (d) the residual wax is then expelled, creating a cavity between the form and the cast which is filled under pressure by the final veneer injected by the press; (e) the dental cast and veneer each have a similar thermal coefficient of expansion.
