Title: Handling system for information carriers
Inventor: SJOEBLOM HANS OLOF
IPC: G07F7/10
Filed: 1990-01-15
Granted: 1997-03-18
Abstract: The present invention relates to a handling system for information carriers such as credit cards (1) and the like, including information stor-ing means such as chip circuits (4) and the like. The essence of the in-vention resides in the feature that a credit card, when not used, is to be unserviceable. To activate a credit card to serviceable condition there is introduced into the chip circuit, by a code transmitter (Fig. 3), one or more states of authority, which are adapted to be read by a transceiver device (28) included in a press copy-ing machine for credit cards (18, Fig. 4). The authority information re-ceived is arranged to be indicated (35) at the press copying machine. The press copying operation is also arranged to control the transceiver device (28) such that a signal is transferred to the chip circuit (4-6) to extinguish the state therein, that is to deactivate the credit card after au-thority indication.

Title: Metalworking fluid management system
Inventor: TUCK IRA T JR
IPC: B23Q11/10
Filed: 1992-10-29
Granted: 1995-02-07
Abstract: A system and process for managing metalworking fluids is disclosed.  The system has a metering device for supplying desired amounts of metalworking fluid components (coolants, lubricants, biocides, etc.) to the metalworking fluid of the system which has been collected from the metalworking area, and filtered.  The use of a variable pump (variable in speed, volume or time) is preferred to ensure that adequate, but not excessive amounts, of the necessary components are added to the system.  Preferably, the metering device is located between the outlet of the filter and the inlet of a metalworking operation.  The system and process reduce consumption of the metalworking fluid, reduce costs, reduce waste generation, and increase filter performance and overall system control.
Patent CA-2085890-C (CA)
Inventor: GILHOUSEN KLEIN S
IPC: H04L1/06
Filed: 1991-06-21
Granted: 2002-01-08
Abstract: A system and method for communicating information signals using spread spectrum communication techniques. PN sequences are constructed that provide orthogonality between the users so that mutual interference will be reduced, allowing higher capacity and better link performance. With orthogonal PN codes, the cross-correlation is zero over a predetermined time interval, resulting in no interference between the orthogonal codes, provided only that the code time frames are time aligned with each other. In an exemplary embodiment, signals are communicated between a cell-site (12, 14) and mobile units (16, 18) using direct sequence spread spectrum communication signals. In the cell-to-mobile link, pilot, sync, paging and voice channels are defined. Information communicated on the cell-to-mo-bile link channels are, in general, encoded, interleaved, bi-phase shift key (BPSK) modulated with orthogonal covering of each BPSK symbol along with quadrature phase shift key (QPSK) spreading of the covered symbols. In the mobile-to-cell link, access and voice channels are defined. Informa-tion communicated on the mobile-to-cell link channels are, in general, en-coded, interleaved, orthogonal signalling along with QPSK spreading.

Title: Improved vehicle tire deflator
Inventor: KILGROW DONALD C
IPC: E01F13/12
Filed: 1993-02-25
Granted: 2003-09-02
Abstract: An improved vehicle tire deflator that is a foldable and can be deployed by pushing it or pulling it to an extended attitude across at least one full traffic lane, and includes a number of rocker arms that are pivotally coupled to base supports to form a frame that is collapsible and when extended, includes a stop arrangement for holding the rocker arms apart. Which rocker arms each include a plurality of actuators and spaced spike base bosses, with each spike boss center holed and countersunk to accommodate an end of a hollow spike and attached resilient grommet fitted therein. With a tire rolling onto which rocker arm actuator, the rocker arm is canted towards the rolling tire tread surface, pointing a hollow spike sharp end at that tire tread to pierce and lodge therein as the tire rolls over it, and with continued tire rolling the hollow spike is pulled from its spike base boss seat and travels fully into which tire, allowing air from within that tire to vent to atmosphere. Alternatively, for penetrating a steel belted tire, or the like, an insert formed of a hard steel, or the like, and having a pointed end is fitted longitudinally into and maintained in which hollow spike without blocking the air passage through which hollow spike, the insert pointed end extending beyond the hollow spike pointed end to first contact the tread of a tire rolling thereover. The resilient grommet absorbs forces as are exerted by the tire rolling over the hollow spike pointed end that would otherwise distort and deform the sides of the spike base boss seat, thereby maintaining the shape of which seat to allow for the replacement of hollow spikes, with or without inserts, fitted therein, providing for deflator reuse.

Title: Methods and systems for gas treatment
Inventor: LYNCH R LARRY
IPC: B01F23/10
Filed: 1993-04-01
Granted: 1995-02-14
Abstract: The present invention provides a process for decreasing the relative humidity of a gaseous or vaporous process stream, while increasing the temperature thereof.  A preferred embodiment of the process of the present invention is implemented using a bleed valve, a positive displacement blower located downstream therefrom, and a control mechanism for opening and closing the bleed valve. When opened, the bleed valve preferably permits ambient air to admix with the gaseous process feed stream to form the blower feed stream.  Increased blower gas throughput results in a lower magnitude gas temperature increase across the blower.  The control mechanism used in the practice of the present invention involves monitoring the temperature of the blower effluent (or the gaseous feed to a downstream unit operation), and controlling operation of the bleed valve in accordance with that temperature reading.

Abstract: An equalization technique for the compensation of degradation caused by multipath Rayleigh fading channels to the transmission of digitally modulatedsignals such as   (see fig. I)   Differential Quadrature Phase Shift Keying (DQPSK) modulated signals. The technique is applicable to both linear and nonlinear transversal equalizers. Based on the Method of Projection onto Convex Sets (POCS), the technique is realized in an iterative form. The convergence speed of equalization depends on the magnitude of a look-back parameter, and is comparable to the speed of recursive least square based equalizers. The computational complexity of the technique also is variable and is adaptable to the convergence speed requirements. For achieving convergence speeds as recursive least square techniques, the computational load required of the presented equalization is of the order of the load required of the recursive least square techniques, but its program implementation is exceedingly simpler. At the same time the code size, memory and power consumption requirements are lower.
