Title: Control of memory access by multiple processors - using operating system allowing different clock rate processors to communicate
Inventor: SAOUMI SAID DIPL ING
IPC: G06F13/18
Filed: 1989-08-15
Abstract: A system is provided for access to a common memory (511) by a pair of processors operating at different clock rates.  The access tubes place over system busses (4.4,4.5) that connect with latch/driver circuitry (5.2,5.3).  An access control and cycle control circuit (5.4) receives access request signals (4.6,4.7) from the processors. The operating system provides an access time that is less than the memory cycle time of the unit with the shortest cycle time.  The system provides inhibition of the access process while an operation is in progress. ADVANTAGE - Allows processors with different clock rates to communicate with memory.

Title: Sealing system for plastic wrapping - uses sonotrode to grip together ends of wrap before ultrasonically welding them, eliminating use of second grip tool
Inventor: LUEDTKE KURT
IPC: B29C65/74
Filed: 1989-10-17
Abstract: Sealing system for a machine which wraps packages has strips of plastic material and films and it welds them ultrasonically by means of a sonotrode and a tool to grip the two ends of the wrap together; in place of a second such tool which has hitherto been used for the process the material is held by the welding sonotrode. ADVANTAGE - Exploits use of a cold sonotrode by causing it to grip the packing strip before it is oscillated and only then making the sonotrode vibrate electrically. Elimiates the conventional second gripping tool and saves tool costs.

Title: Bottle with measured delivery mechanism -  has nozzle dia. chosen to allow, exit of fluid while preventing inlet of air
IPC: G01F11/26
Filed: 1990-08-31
Abstract: The bottle has a dosing mechanism for measuring out fluids. It uses a liq. dispenser in the form of a fastening part and delivery nozzle is set in the mouth of the bottle neck and the dia. of the nozzle is considerably less than the dia. of the bottle neck. The nozzle dia. is set according to the surface tension of the fluid (F) to be dispensed so that in the delivery position fluid (F) can at first run out but air cannot enter the bottle (1) and the air located in the bottle holds the fluid back in the bottle through suction and the surface of the fluid to be dispensed maintains the ensuing hydrostatic pressure of the fluid in the delivery nozzle. USE/ADVANTAGE - Simplified use by turning the bottle from a rest position with the neck upwards 180 deg. into the useful position.

Title: Automatic necktie and lining sewing attachment -  has distance pieces which allow sewn necktie to be removed
Inventor: KAWASHIMA WASABURO
IPC: D05B39/00
Filed: 1990-10-06
Abstract: The sewing machine attachment, for automatic stitching to fix a lining to a necktie, has a pair of distance pieces on the left and right sides to maintain a gap between the right side of the fabric and the lining material. They can be moved out from the zone of the passage slit for a needle. The pressure plate moves upwards when the frame is turned up and the freely moving slide lies at the upper point of the guide rail through the action of the rotating table, or runs along the upper point. The frame lays the lining fabric on the stage with its right side downwards and its pointed end is hemmed by the needle. The profiled edges are spread over the needle passage area and the pressure plate is turned down to press against the lining fabric. The distance pieces are positioned to overlap the lining fabric slightly and the tie fabric is laid on the plate with its reverse side upwards, it is hemmed by the needle and its profiled edges are laid over the slit. The slide is moved from the upper to the lower point at the three apex points slightly above and below the distance pieces to hold the sections together as the frame is lowered. The sewing machine stitches the materials automatically with the needle moving through the passage slit through the movement of the sewing maching and the stage. The frame is raised, and the necktie is removed. ADVANTAGE - At the end of the sewing operation, the sack-shaped section of the necktie can be removed from the lining material pressure plate as soon as the side distance pieces have been moved clear and without fouling the distance pieces.

Title: Lead sheets for covering roofs - have parallel double folds to allow length to be adjusted
Inventor: LEWITZ JUERGEN
IPC: E04D13/147
Filed: 1990-10-06
Abstract: A roof is covered and sealed with lead sheets. Each sheet has parallel folds (7, 7') with the material being folded double with four successive double folds. The distance between successive folds (7, 7') is significantly greater than the overall width of the folded sheet. The overall thickness of the folded sheet in the region of the fold is determined by the number of layers of material in the region of the fold. - These folds enable the effective length of each sheet to be adjusted to ensure that the roof is properly sealed, especially around the frames of roof windows.

Title: Temperature control method for ceramic hotplate - using proximity control and progressive power reduction to approach set temperature
Inventor: GRIMM DIETER
IPC: G05D23/19
Filed: 1991-02-15
Abstract: The heating element under the ceramic/glass hotplate has a temperature sensor operating between max. and min. settings. When the temperature reaches the max. setting the power is turned off. The power is switched on again when the temperature cools to the min. setting, but applied at a computed lower rating. This is repeated until a power level is reached which raises the temperature to just below the max. which is the selected cooking temperature. The reduction in power is computed from the time taken to drop between max. and min. levels, and the time taken to rise back to max. level. A processor provides the progressive control. If the max. switch=off does not operate within a set time then the power is increased slightly. ADVANTAGE - Accurate temperature control, no excessive temperature cycling.

Title: Automatically charging accumulator, e.g. for remote control applications - applying rapid charge period followed by test cycle and further charging cycles with currents dependent on charge
Inventor: OTTERBEIN JUERGEN
IPC: G01R31/36
Filed: 1991-02-23
Abstract: A method of charging an accumulator involves rapid charging with a relatively high charging current which is interrupted after a first time interval. The accumulator is automatically connected to a test circuit and loaded with a test load. At the end of the test interval a charge parameter is compared with a threshold. The test cycle is interrupted and the accumlator charge over a second interval with a current dependent on whether the threshold was exceeded or otherwise. After a second charging period the previous steps are repeated with the exception of rapid charging. USE/ADVANTAGE - For locomotive used to move parts of railstock within station. Rapid charging is achieved with prevention of faulty operation and overcharging without continuous operator monitoring.
