Abstract: A drive axle assembly (10) has a gear housing (12),  two axle tubes (14, 16) extending outwardly of the gear housing, a lubricant reservoir (30) in the gear housing and a gear assembly (18) rotatably mounted in the gear housing that has a rotatable ring gear (24) that is partially disposed in lubricant in the lubricant reservoir.  The drive axle assembly also has a lubricant cooling system that includes a cooler cover (26) that is attached to the gear housing to provide a lubricant passage (34) in fluid communication with the lubricant reservoir via an inlet  (44)  that is juxtaposed the rotatable ring gear.  The lubricant passage has elevated outlets (40A, 40B) that are connected to the respective axle  tubes.   The  axle tubes  are  connected to the reservoir via restricted outlet passages (47) that are below the outlets of the lubricant passage.  The outlets of the lubricant passage and the axle tubes are sized so that there is a flood of lubricant in the axle tubes when the rotatable ring gear is driven at or above a predetermined speed.  The flood of lubricant extends for the length of the axle tubes and cools the lubricant in the axle tubes.  The rotating axle shafts are immersed in the flood of lubricant and churn the lubricant in the axle tubes to enhance heat transfer.

Abstract: A machine frame (1) with two side members (6) at its ends comprises support arms(7,8), which are pivotably mounted in half-round bearing supports (9). The bearing supports (9) can be arranged on differently high pedestals (20), which results in different inclined positions for the machine frame (1) and thereby variable looping angle (.beta.) at the drive pulley (2) and cable spacing (a) between the cage cables (15) and the counterweight cables (16). Furthermore, the deflecting roller (3) is mounted in laterally displaceable bearing plates (5), wherein the deflecting roller (3) can in addition still be inserted above or below the side members (6). The variable position of the deflecting roller (3) likewise has an effect on the looping angle (.beta.) and the cable spacing (a). The combination of the two possibilities of adjustment in respect of inclined position and deflecting roller position enables the enlarged adaptation of machine frame (1) to different cases of application.

Title: Apparatus and method for constructing a mosaic of data
Inventor: LOGAN MARK J
IPC: G06T1/00
Filed: 1995-11-03
Abstract: Apparatus and method are provided for combining, in real time, weather radar data in digital format from multiple radar sites into a mosaic covering a regional or national area (e.g., the continental United States). Such apparatus and method is designed to be implementable as computer software and to run on a general purpose computer such as a personal computer. Such apparatus and method preferably utilizes a database of "lookup tables" which are used to project individual radar data bins directly to a grid of the desired coordinate system for that mosaic. Using these lookup tables, each of a plurality of radar data bins is converted to a corresponding grid location or box in a mosaic image. While each radar data bin is mapped to a grid box for the mosaic, not every such grid box within the coverage area of the radar may receive such a data bin. Any resulting holes in the produced mosaic are then identified using yet another grid whose locations correspond to those of the mosaic but which instead provide information regarding the data then appearing in corresponding locations in that mosaic. Each such hole is then filed with data from the locationally closest data bin.

Title: Process for recovery of metals from used nickel/metal hydride storage batteries
Inventor: KOEHLER UWE
IPC: C22B3/40
Filed: 1995-12-01
Abstract: An H2SO4/H2O2 mixture that dissolves in particular the AB5 type hydrogen storage alloys that form the main component of negative electrodes without leaving any residues is suitable to disintegrate the fine fraction containing the positive and negative electrode active material mechanically separated from scrap accumulators. Excess H2O2 is then destroyed and Fe3+ is reduced into Fe2+ by flowing the strongly acid disintegration solution over the metallic coarse fraction, so that the rare earths from the storage alloys may be precipitated as double sulphates without Fe impurities. Ni and Co may be recovered together by solvent extraction and simultaneous electrolysis. The separated product may be used as pre-alloy for producing new hydrogen storage alloys. The process may be carried out without problems even when because of sorting errors the scrap accumulators contain a small proportion of Ni/Cd batteries.

Filed: 1997-07-18
Abstract: Bags, primarily for liquid or other flowable products, are formed from sheet plastics material to define a generally rectangular container closed at one end and with a filling and discharging arrangement at the other end. The bags are formed from an outer sheet 10 and an inner sheet 11, the outer sheet extending the full length of the bag whereas the inner sheet extends only part way along the bag. The outer sheet defines pockets 15 which act as the corners of the rectangle and the inner sheet extends across the corners of the rectangle and is connected to the outer sheet adjacent the edges of the pockets. The bag is made by feeding the two sheets of material onto a table, the outer sheet 10 lying below the inner sheet 11. The outer sheet is drawn down to form the pockets 15 at spaced locations along the table. The inner sheet is then welded to the outer sheet at 18, 19 adjacent the edges of the pockets. The ends of the inner and outer sheets are then drawn over, overlapped and connected together to form a tube and one end of the tube is closed to form the base of the bag. The other end is the filling opening which can be closed after the bag is filled.

Abstract: A crimping device for crimping end fittings on hoses and tubes includes a base ring an Ud a pressure ring.  The base ring includes a frustoconial inner surface in which is positioned a die assembly which, at its opposite end, abuts a portion of the pressure ring.  When the pressure ring is pushed toward the base ring, the dies converge,crimping the fitting to the hose or tube.  In order to properly locate the hose or tube, a locator pin is affixed to the pressure ring by an L-shaped bracket.  The locator pin, pressure ring and crimping die assembly form a tool package which, upon being initially set, does not have to be reset for subsequent uses.  The tool package can be stored while other tool packages of a similar configuration are set, used and then stored forsubsequent use.  In this way, the irritation and resulting inefficiency of having to continually reset tooling is minimized.
