Title: Reinforced tile mat base and modular carpet forming system
Inventor: RODGER MALCOLM DAVID
IPC: A47G27/02
Filed: 1990-07-27
Granted: 1997-02-18
Abstract: This invention relates to a novel reinforced carpet tile mat base and modular carpet framing system. More particu-larly, the invention relates to a novel modular carpet tile mat construction which is specifically adapted to hold carpet tiles in a fixed position so that they may be used in combination as a floor mat or a covering for part of a floor area, as a self-contained floor covering.  The invention comprises carpet tiles, a mat base, and a mat frame.  The mat base comprises: (a) a reinforcing layer, comprising woven or spun-bonded polyester, nylon or polypropylene fibres; (b) a plastic binder enveloping and completely immersing the reinforcing layer, thus binding the fibres of the reinforcing layer together; and (c) a first and second layer of resilient expanded foamed polymer or rubber distinct from the plastic binder (b) and adhered to a first and a second opposing side, respectively, of the plastic-immersed reinforcing layer. The mat frame holds the mat base and carpet tiles in compression. The mat frame having bevelled edges to facilitate the movement of wheeled traffic on and off the carpet tile mat. A feature of the invention is that the immersion of the reinforcement layer in a polymer plastic binder affords dimensional stability to the mat base against stretch and trap-ezoidal distortion as well as rigidity to receive compressive forces. Another feature of the invention is that it can be installed without adhesives between the carpet tiles and the mat base or the mat frame.

Title: Discriminating charger and compatible battery
Inventor: SPELLMAN PATRICK
IPC: H01M50/548
Filed: 1993-10-28
Granted: 1996-04-16
Abstract: A charger for a rechargeable alkaline manganese (RAM) battery has a positive contact which engages against the positive terminal of a compatible battery without making electrical contact with the positive terminal protruding nubbin. A rechargeable battery has an insulating jacket which surrounds the battery side wall but which does not overlap the positive terminal. Hence the charger positive contact may engage against the specially adapted battery and electrical contact, but will not make electrical contact with a conventional battery having a partially insulated positive terminal. Alternatively, the battery positive terminal may be insulated within less than 0.040 inches of the battery perimeter and be charged by protruding positive contacts spaced inwardly from the perimeter by approximately the same amount.

Title: Feedforward amplifier for detecting distortion of an input signal
Inventor: FUKUCHI AKIO
IPC: H03F1/32
Filed: 1994-12-22
Granted: 1998-08-18
Abstract: A feedforward amplifier employs four steps to reduce distortion. In the first step, a control circuit detects the frequency of an input signal and the distortion generated by amplification of this input signal, and sets the frequency of a pilot signal output from a variable frequency oscillator to a value other than the input signal frequency and the distortion frequency and close to an average value of the input signal. Thereafter, the control circuit controls a distortiondetecting loop by using the pilot signal in the second step and controls a distortion removing loop in the third step. In the fourth step, the control circuit succeeds the control of the distortion removing loop in a normal state and further controls the distortion detecting loop only when environmental changes have occurred.

IPC: C22B3/26
Filed: 1995-03-20
Granted: 1999-03-09
Abstract: The invention provides a hydrometallurgical process for the recovery of metals. In particular, an aqueous feed solution originating from acid leaching is provided. The aqueous feed solution contains nickel and/or cobalt ions. The pH of the solution is maintained at a level between about 2 and 6. The aqueous feed solution is contacted with a water-immiscible organic phase containing an extractant to load the nickel and/or cobalt metal ions to form a metal-bearing organic phase. The extractant has at least one organic soluble dithiophosphinic acid, alkali, alkaline earth metal or ammonium salt thereof. The aqueous feed solution has sufficientlylow levels of chromium (VI) ions, iron (III) ions and copper ions to allow repeated use of the extractant. The metal-bearing organic phase is then separated from the metal-containing aqueous feed solution. Finally, after separation from the aqueous feed solution, the metal-bearing organic phase is contacted with an aqueous strip solution to recover the loaded nickel and/or cobalt from the metal-bearing organic phase.
