Title: Method and device for protecting busbars
Inventor: BERTSCH JOACHIM
IPC: H02H7/26
Filed: 1995-04-18
Abstract: In a busbar protection method and a corresponding device, the maximum values of the currents in the outgoers are determined. The maximum values Ikmax of the current characteristics are extended by a certain hold time th. Subsequently, these current characteristics are processed further vectorially. With the aid of these current characteristics Ik changed in such a way, a fault signal is calculated by means of a protection algorithm, preferably the current comparison method with current stabilization or the phase comparison algorithm. It can be uniquely determined on the basis of the extension of the maximum according to the invention whether an external fault or an internal one is concerned. The advantage of the method and of the device according to the invention resides, in particular, in that the localization of the fault is possible in a reliable fashion even in the case of strong saturation of the current transformers. Above all, false tripping can be reliably avoided even in the case of external faults.

Title: Gaming machine island
Inventor: TAKEMOTO TAKATOSHI
IPC: A63F7/02
Filed: 1994-09-19
Abstract: 27 The number of parts is decreased for reducing costs. When a transport unit 70 and an introduction unit 80 are connected, if problems occur because of the outer frame dimension difference between gaming machines 11 or a combination of a gaming machine 11 and a pachinko ball lending machine 20, the transport unit 70 and the introduction unit 80 are expanded or contracted in a transport direction. If the transport unit 70 and the introduction unit 80 are set to a predetermined length, then both the units are fixed by adjustment screws 85b and 86b. This eliminates the need for manufacturing new transport units 70 or introduction units 80 of different types.

Title: Method for treatment and decolorization of waste water from cosmetic manufacturing processes
Inventor: CARR CHARLES W
IPC: C02F1/52
Filed: 1995-06-28
Abstract: The invention is a method for the treatment and decolorization of waste water incident to the manufacturing of cosmetic products that contains dyestuffs, fatty organic chemicals and other organic chemicals. The method requires a strong basewhich is added to the waste water at a suitably high temperature to cause flocculation of fatty substances.  Then a strong colorless oxidizer is added to reduce the hydrophilic  character  of  the  remaining organic  chemicals and cause partial decolorization. The resulting waste water is in a state that can then be decolorized with powdered activated carbon. Finally, the powdered activated carbon is separated from the waste water. The decolorized waste water is discharged in compliance with acceptable water quality standards for plant effluents.

Patent CA-2153743-A1 (CA)
Title: Load limited connector
Inventor: CLIFTON DAVID G
IPC: H02G1/08
Filed: 1995-07-12
Abstract: A load limited connector that is calibrated to fail at a predetermined approximate tensile load. The connector includes a main body, within which a pin chamber is received, and a secondary body having a shaft that is releasably secured within the pin chamber. At least one breakaway pin, positioned in a pin passageway passing through the pin chamber and into the main body, secures the pin chamber within the main body. When the connector is subjected to tensile loading that exceeds the yielding point of the breakaway pin, failure of the pin occurs resulting in separation of the main body from the secondary body. A pair of torsion pins extend through the pin chamber into the main body to prevent rotation of the pin chamber relative to the main body.

Title: A method to separate fibres from each other in water and a moulding composition for plastic forming of fibre products
Inventor: G SLAND STEIN
IPC: D21B1/14
Filed: 1994-01-27
Abstract: The invention describes a method for dispersion of cellulose based fibers in water. The raw material, which particularly may be recycled paper, is first wetted with water. By a combination of addition of hydrocolloid which binds water, and strong kneading at high solid content, the mixture is transformed into a modulable paste. The high viscosity of the paste effectively conveys the shear forces of the kneading machine to make the fibers flexible and tear them apart. When the kneading is terminated, the hydrocolloid prevents the fibers from reassociation into fiber bundles.

Title: Vibration isolator for a portable power tool
Inventor: PETTET GLENN A
IPC: A01D34/68
Filed: 1994-07-06
Abstract: A hand held power tool is disclosed comprising an internal combustion engine, a workpiece driven by the engine, a boom extending between the engine and the workpiece, a clutch housing (54), a starter module (52), and an isolator (58). The clutch housing (54), the starter module (52), and the isolator (58) are disposed in a rearward section of the power tool housing the boom. The isolator is preferably formed of thermoplastic rubber, and is disposed between the clutch housing and the starter module. The clutch housing (54) and the starter module (52) are connected by fasteners (56) extending therebetween, but the fasteners do not penetrate the isolator (58). Because the isolator is soft mounted, the isolator effectively dampens engine vibration forces to the operator and avoids local stresses which might otherwise lead to premature failure.

Filed: 1996-06-04
Abstract: An improvement in a method for the inhibition of scale deposition on the surfaces of a well coproducing oil and scale forming brines, said method comprising injecting into the well reservoir an acidic aqueous solution at a first pH containing dissolved therein a scale inhibitor, multivalent metal ions, and a heat-sensitive pH-increasing substance which decomposes at elevated temperatures liberating an alkaline compound such that the solution is inherently heated by the higher ambient reservoir temperature to a temperature at which the alkaline compound is liberated from the heat-sensitive substance thus raising the pH of the solution to a point at which a sparingly soluble multivalent metal salt of the scale inhibitor is phase separated from the solution on the porous surfaces of the reservoir rock formation, providing for a slow release of inhibitor into the produced brines when the well is in its production phase. Such improvement comprises injecting as a preflush before said injection of inhibitor solution and optionally as an afterflush after said injection of inhibitor solution, a solution of a heat sensitive pH-increasing substance and multivalent metal ions.

Title: Multiple mode personal wireless communications system
Inventor: ZICKER ROBERT G
IPC: H04M1/72505
Filed: 1995-01-31
Abstract: A multiple mode, personal, wireless communications system exists within a radiotelephone network serving general customers and provides additional services to a select group of customers. The system uses handsets (32) which automatically switch between a standard cellular radiotelephone mode of operation (1901) and an enhanced cordless mode (1420) when the handsets (32) are within range of pico cells (26) that are interconnected to the public switched telephone network (20). Each pico cell is controlled via a framework of overlay cells (10b) that operates independently of the radiotelephone network and uses a unique control protocol on a small number of reserved cellular channels. Each pico cell consists of a spectrally dynamic, non-capturing, frequency agile, multi-purpose base station (26) provided at customerselected locations to cooperate with the overlay cell framework. Each pico cell is capable of supporting multiple handsets (32) and using low power operation that achieves limited coverage. Each pico cell reduces traffic on the standard cellular radiotelephone network by independently handling registered handsets (32). An alternate line option module (22) provides wireless local interconnect capability to selectively route call traffic between land lines (24) and the standard cellular radiotelephone network. Service control units (12) and host stations (17) facilitate wireless activation and control of each pico cell and handset (32) via the overlay cell framework.
