Title: Digital image processor esp. for character representation - provides correction of luminance values to counter aliasing effect at image boundary
Inventor: UEDA NAOFUMI
IPC: G06T11/20
Filed: 1991-02-20
Abstract: The generation of character images for display on a VDU as part of a desk top publishing package is carried out using a process that provides an anti-aliasing function to prevent boundary lines being reproduced with a zig-zag pattern. The system is bus structured with a printer (50) and scanner (60) coiupled via an I/O interface (70), together with a main processor (10) and page memory (30). Coupled to the page memory, a correction processor (40) adjusts luminance values based upon a comparison to limit the levels in relation to the boundary.

Title: Play-free ball bearing with two-part outer ring - has radially outwardly projecting spring tension elements moving inwards
Inventor: ZERNICKEL ALEXANDER DIPL ING
IPC: F16C35/067
Filed: 1991-03-18
Abstract: The spring (11+12) is supported by its end remote from the outer ring against the cylindrical element (5) which encloses the two outer ring parts.

Patent DE-4119029-A1 (DE)
Inventor: BOMMARIUS ANDREAS DR
IPC: C12N9/78
Filed: 1991-06-10
Abstract: 2.1. Arginase mixtures, e.g. for the preparation of L-ornithine from L-arginine, have the disadvantage that only a small fraction of the enzyme can be recovered after the reaction has taken place, and thus, together with the high costs of the enzyme, industrial production of L-ornithine in this way is uneconomic. The invention is intended to provide an enzyme-stabilised arginase mixture so that L-ornithine can be prepared with considerably lower numbers of enzyme used. 2.2. The stabilisation of the arginase mixture is achieved by adding a reducing agent which should be present in at least 10 times the molar amount relative to arginase. 2.3. Enzymatic preparation of L-ornithine from L-arginine and arginase kits therefor.

Title: Time-variable adjusting magnitude transmission e.g. for car radio - transmitting magnitude as amplitude change of stereo pilot tone and correlating on reception
Inventor: VENUS ACHILLES
IPC: H03G7/00
Filed: 1991-07-03
Abstract: The transmitted adjusting magnitude is derived from an allocated broadcasting program signal. It is then transmitted together with the program signal to influence its reproduction level at the reception side. It is used for selection of a reproduction dynamics, deviating from the program signal dynamics. The adjusting magnitude is transmitted as an amplitude variation of the stereo pilot tone and is correlated to the instantaneously received broadcasting program signal. Pref. the adjusting magnitude precedes the allocated program signal by a fixed time period. At low program signal level, the amplitude of the pilot tone may be increased and vice versa. USE/ADVANTAGE - Improved reception and reproduction of transmitted signal, without disturbing program signal and time shift between program and adjusting signal.

Patent DE-4132166-A1 (DE)
Inventor: FIEDLER KARL
IPC: G01B21/00
Filed: 1991-09-27
Abstract: Multi-coordinate feeler heads are used on measuring machines and on machine tools in order to measure workpieces. In the case of measuring and controlling feeler heads, the accuracy and reproducibility of a measurement largely depends on the mounting of the feeler (2) relative to the feeler head housing (4). The mounting according to the invention is constructed as a multipoint bearing having a multiplicity of bearing points. Each bearing point consists of a bush (14), integrated into the measurement plate (10), as a mating body for a ball (15) which serves as bearing body and can be aligned in the base (13) of the feeler head housing with respect to the bush (14). The automatic setting of the ball (15) is ensured by arranging for the ball member (16) which supports the ball (15) to be mounted rotatably in a seat (18). In the event of a defective alignment between the bush (14) and the ball (15), a torque acting on the ball member (16) effects an alignment of the ball (15). In the set, stable position, the ball member (16) is fixed relative to its seat (18).

Patent DE-4240654-A1 (DE)
Inventor: STASCHEWSKI HARRY
IPC: B65G23/44
Filed: 1992-12-03
Abstract: In known removal apparatuses for elongate material, the roller chains on which the clamping jaws are fastened must be manually retensioned. If this retensioning does not take place soon enough, increased wear of the roller chains and of the chain wheels can occur. The novel removal apparatus has tensioning elements (41) which exert a tensile force in the direction away from the drive chain wheels (33) on the at least two tensioning chain wheels (35) which are displaceable with their bearing housings (37) in the longitudinal direction of the roller chains (19). A self-locking wedge (99) prevents the tensioning chain wheels (35) from oscillating back and forth. The automatic resetting of the roller chains (19) reduces the wear of the removal apparatus (17) and avoids speed changes during transportation of the elongate material (23). The removal apparatus according to the invention is suitable in particular for transporting cables and pipes. <IMAGE>

Filed: 1993-02-03
Abstract: An intermediate plastic film, for use in processing further or for the prodn. of shapes (esp. flat sheets) is obtd. by reprocessing plastic films; the latter are reduced to flakes and strips and, either in these forms and/or in other form, are sorted for use according to their size, shape, properties, type of polymer and quantities.New or used films are broken up, sorted as described, and packed ready for use. Thus for industrial applications the material can be provided in containers, etc., whereas for e.g. private use it is produced in 1kg lots. If the material is produced from e.g. domestic waste the reduced film is washed, whereby the films float, are removed and dried. Other materials such as wood, thermosetting resins, pigments, etc. can be added and the mixed prods. packed according to the make-up. An advantageous form for the film is splinters of square cross-section needles, as they are useful for reinforcing e.g. pastes.
