Abstract: The invention relates to a process for determining the quantity of plastic granules removed over time by an extruder (1) from a feed hopper (6) whose outlet (7) opens into the inlet (8) of the said extruder, in which process granules are constantly directed into a storage container (16) and a feed-quantity of granules is intermittently directed into the feed hopper, in which process the feed hopper is weighed before or after it is fed, when feeding commences, or when feeding is at an end, and the time required to remove the quantity of material resulting from the weighings is measured, and in which process the throughput of material over time is calculated from the quantities of material removed from the feed hopper in the times measured. In order to achieve the object of further developing a process of this type in such a manner that it also ensures a uniform material feed into the extruder when edge-strip material, in addition to granules, is fed to the cyclone-shaped container, the storage container is used essentially only as a mixing container and an additional batch-preparation container (13) is disposed between this and the feed hopper. The storage container opens into this batch-preparation container. At least one component of the granules and recycled edge-strip material is fed continuously into the storage container. The feed hopper and the batch-preparation container are weighed at time intervals and the feed rate of the at least one component of the granules is increased or reduced accordingly when the measured total weight of the two containers deviates from a predetermined reference weight.

Abstract: Using this device, noise and vibration which occur during actuation and unlatching of a shaft door (1) which is moved by a driven car door (2) can be largely prevented. To this end, a first coupling element (3) which is mounted on the shaft door (1) and a second coupling element (4) which is mounted on the car door (2) are constructed as magnets and are arranged in such a manner that a north pole (N) of the first coupling element (3) is opposite a north pole (N) of the second coupling element (4), and a south pole (S) of the first coupling element (3) is opposite a south pole (5) of the second coupling element (4), separated by an air gap in the movement direction of the doors. Provided on a latching element of the shaft door (1) is a further magnet whose one pole is located opposite a similar pole of the second coupling element (4), with an air gap, in the movement direction of the doors. When a car stops at a floor, the repulsion forces of the magnets initially unlatch the shaft door (1) without being touched, and then move without being touched when the car door (2) opens.

Abstract: A controlling apparatus which can control a continuous electrolytic ion water producing apparatus so that the electrolyzing capacity of an electrolytic cell is kept fixed against a variation of the flow rate or the quality of water upon passage of water to always achieve optimization and stabilization of electrolytic ion water produced. When water flows through the electrolytic cell (5), it is energized by a power source circuit (10) to electrolyze the water to obtain electrolytic ion water. When a range change-over switch is manually operated, a dc voltage of the power source circuit is controlled in response to the range change-over switch by a control unit (40) and a switching regulator (16) to produce an electrolyzing voltage corresponding to the operated position of the range change-over switch. The water is thus electrolyzed with an electrolyzing strength of the electrolyzing voltage. During such electrolyzing operation, if the flow rate or the water temperature varies, then the pulse width of the switching regulator is corrected to automatically adjust the electrolyzing strength in accordance with the varying condition thereby to always keep the electrolyzing capacity of the electrolytic cell fixed.

Abstract: A cantilever-type wiper arm (24) has a unique shape that allows it to meet its structural requirements, is aerodynamically efficient, and also allows it to be efficiently moulded as a fibre-reinforced, composite structure. In cross-sections taken along its length, the arm comprises a series of symmetrical ellipses of nearly constant area. The arm (24) is arranged so that, in use, the major axes of each of the ellipses of the cross-sections are parallel to the windshield (20) of a motor vehicle on which it is used. The base section (A) of the arm (24) is wider and thinner, giving good up and down flexibility combined with good side to side stiffness. The tip section (C) of the arm (24) is narrower and thicker, thereby maintaining the same basic profile, but imparting more torsional rigidity. The intermediate section (B) of the arm (24) provides a smooth transition from the base section (A) to the tip section (C). The smooth shape and constant area of cross-section allows the arm (24) to be moulded as a fibre-reinforced composite structure with a constant fibre-to-resin ratio all along its length.

Abstract: A data storage system includes on-chip circuitry that stores the preceding reference line of data and provides fast access time to data in this line with no need for special pins to signal an "in-line" access. The system includes an array that comprises 2   K    storage registers, each storage register storing an N-bit data element. Each register has a bit access address associated therewith. The array is responsive to K-M address bits provided at its address inputs to provide 2   M    data elements at its data outputs. A line buffer (24) receives the 2   M    data elements from the data output of the array. Access control (28) circuitry responds to the K-M address bits for loading the 2   M    data elements from the data outputs of the array to the line buffer. Select circuitry (26) responds to the M address bits for transferring a single data element stored in the line buffer (24) and identified by the M address bits to the select circuit in parallel with the array access. In a preferred embodiment, the access control circuitry (28) includes means for comparing the address presented on the address inputs of the array to the address of the line stored in the line buffer (24). If the two addresses match, then the array access is aborted.
