Title: Roller bearing - has sliding mechanism to bring roller pair surfaces into and out of operation
Inventor: BENNER FRANK
IPC: D21G1/02
Filed: 1992-08-25
Abstract: Rollers in pairs are held in bearings which separate so that when not in operation the surface of the rollers will not be damaged. The two bearing surfaces are close together and by means of angled surfaces and recesses they can slide to bring the roller faces together, or separate them. The two bearings (1, 2) are brought together on assembly, in direction (A), so that faces (a1, 2a) close in proximity. The bearing (1) is lifted by another element, so that the nose (4a) of the hinged lever (4), which lies in the recess (3), is lifted above the lug (7a), and engaged by it. The lever (4) is pressed by the flat spring (5) so that it lies with its end in the slot (7), when the faces (1a, 2a) are in contact. ADVANTAGE - The bearing arrangement takes the roller operation out of action in a short movement, without the requirement of expensive equipment.

Date Jul. 7, 1994Anodized aluminum surfaces are electrolytically colored using alternating current in a process in which two different coloring baths are sequentially employed. One bath contains copper(II) ions and an additive which improves throwing power thereby providing uniform distribution of the depth of color. The other bath contains tin(II) ions, silver ions, or both tin(II) and silver ions. If tin(II) ions are included, additives which stabilize tin(II) ions and improve throwing power are also included. Either bath may be used first. The use of two separate coloring baths provides colored aluminum surfaces which have excellent resistance to corrosion. Workpieces with reddish-gold hues and darker tones can be produced.

Inventor: WIRTHWEIN UDO
IPC: E01B9/68
Filed: 1993-04-28
Abstract: A resilient rail fastening device (4) has an elastic intermediate layer (8) arranged between a rail foot (2) and a hard support, for example a sleeper (6), provided with a profile. The compression surface (17, 18) which faces the support (6) has substantially closed marginal strips (10-13) which in turn enclose a depressed surface (17, 18) from which project individual small-surface compression point (11). Such a geometric design of the elastic intermediate layer (8) allows a certain elastic rigidity of the intermediate layer (8) to be adjusted by modifying the compression surfaces (17, 18). A thermoplastic elastomer of non-crosslinked rubber or an ethylene-vinyl acetate copolymer are preferably used for the intermediate layers (8). Such intermediate layers are particularly suitable for highly stressed railways with a W-shaped superstructure. A special injection molding tool with exchangeable plates for shaping compression surfaces of different sizes is also disclosed.

A transport vehicle according to the invention, the change mechanism of which meets these requirements, is presented. On the undercarriage (8) of the transport vehicle (7), a change mechanism (20) is assigned to each standing place (15e) of a can (13e). The change mechanism (20) has a slide (22) for standing a can (13e) on it, the said slide (22) being displaceable relative to the undercarriage (8) perpendicularly to the direction of movement (14) of the transport vehicle (7). The slide (22) is assigned an apparatus (23) for displacing the can on the slide, for depositing the can from this slide and for picking up the can onto this slide. <IMAGE>

Title: Semiconductor permanent memory device
Inventor: TANAKA TOMOHARA
IPC: G11C17/00
Filed: 1994-09-16
Abstract: A NAND-cell-type EEPROM comprises a memory cell array, in which electrically overwritable memory cells are arranged in matrix form and a multiplicity of data circuits (L/S circuits in a main-bit-line control circuit) for the storage of data for controlling the state of a reading operation of data in memory cells in the memory-cell array. A bit-line voltage is controlled according to the writing data in the data circuit after the loading of the data. Since the voltage on the bit line changes when there is a current leakage, a faulty writing operation caused by a defective bit line with a current leakage can be prevented by setting the data in the data circuit which specify that the bit-line voltage has been sampled after the loading of the data. This makes it possible to carry out the data loading a short time after the writing mode is switched on, and creates an easy-to-use NAND-cell-type EEPROM with a high relief efficiency for defective bit lines. <IMAGE>
