Title: Training apparatus for cattle roping
Inventor: THOMAS DARRELL E
IPC: A63B69/00
Filed: 1993-03-01
Abstract: ABSTRACT OF THE DISCLOSURE A training apparatus is provided for cattle roping to be used by a roper.  The training apparatus includes a frame assembly and straps for securing the frame assembly to the body of the roper.

The apparatus allows a roper to simulate a variety of roping conditions likely to be encountered.
Patent CA-2090855-A1 (CA)
Title: Membrane module
Inventor: KASCHEMEKAT JUERGEN
IPC: B01D63/10
Filed: 1991-09-10
Abstract: A spiral-wound pervaporation module, incorporating membrane envelopes (2), within and between which are channels through which the feed and permeate streams flow. The feed and permeate channels are created by feed spacers (3) and permeate spacers (4). The module is unconventional in that the permeate spacer is tailored for optimum permeate flow throughput, based on the discovery that the total permeate flow throughput passes through a maximum as the resistance to vapor transport of the permeate spacer material is progressively decreased. The resistance to vapor transport along the permeate channel is kept below a value at which it has a significant adverse effect on the membrane flux and the membrane separation properties, yet at the same time the total module throughput is within an optimum range. The increase in throughput per unit membrane area obtained more than compensates for the loss in membrane area brought about by use of a thicker permeate spacer.

Patent CA-2095065-A1 (CA)
Inventor: CLAUS DAVID M
IPC: G06Q20/36
Filed: 1993-04-28
Abstract: A secure toll payment system is realized by transmitting a changeable encryption code from roadside equipment at a toll plaza to a moving vehicle. Thereafter, the moving vehicle uses it to encrypt payment information according to the Data Encryption Standard algorithm. The moving vehicle transmits the encrypted payment information to the roadside equipment which performs a credit or debit transaction. Because the encryption code changes from time to time, so toodoes the nature of the signal which is transmitted by the vehicle; and fraud, based on electronic eavesdropping, is substantially eliminated. The encryption code comprises an 8-bit random number and a time/date number. Vehicle-mounted apparatus includes a transponder unit and a portable smart card which inserts therein. The roadside equipment includes a pair of spaced-apart antennas that are sequentially located along an express payment lane at a toll plaza and a computer (Plaza Server) which controls them.

Inventor: FUENTES JAMES J
IPC: H04M7/00
Filed: 1993-05-31
Abstract: This invention relates to a method and apparatus for offering wireless telecommunication service. A switch such as an automatic Private Branch Exchange (PBX) (30), equipped to communicate with Integrated Services Digital Network (ISDN) station sends ISDN signaling messages to and receives ISDN signaling messages from a protocol converter (20). The protocol converter, which also communicates with a wireless cell site (10), converts messages between the ISDN protocol and a protocol for communicating with the wireless cell site. The cell site sets up wireless connections to a mobile station (1), essentially in its prior art mode, and the PBX (30) sets up connections to the cell site (10) essentially in its prior art ISDN station control mode. The system can also hand off calls from one cell site to another connected (via 47) to the same PBX, using the protocol converter to generate and distribute the locate request messages. The system can further process roamers by allowing them to register locally and by directly connecting intra-system traffic to such roamers. <IMAGE>
Patent CA-2098332-A1 (CA)
Inventor: GAGAS JOHN M
IPC: E03D5/00
Filed: 1993-06-14
Abstract: An overflow controller detects and prevents the introduction of supply fluid into a receptacle beyond a predetermined level.  A vertical overflow chamber is in communication with the receptacle and contains a float which is buoyed by fluid entering the overflow chamber when the fluid level in the receptacle increases above the predetermined level.  The float preferably interacts with a proximity detector that senses the float when it moves sufficiently close.  As the float rises towards the sensor, the sensor is activated to produce an output which is received by a fluid controller.  The controller then prevents any supply fluid from being added to the receptacle.

Title: Circuit arrangement for evaluating the signal of a capacitive measuring sensor
Inventor: SCHELER BERND
IPC: G01N27/22
Filed: 1993-07-09
Abstract: A circuit arrangement for evaluating the signal of a capacitive measuring sensor (Cs) in particular a humidity sensor comprises a multivibrator (MV) which is remotely adjustable with respect to its frequency in order to provide a frequency independent from the measuring value as well as a monoflop (MF) which is triggered by the trailing edge of the pulses of the multivibrator and where the pulse length is determined by the measured value of the capacitive measuring sensor (Cs) connected to it. The pulses formed by the monoflop (MF) are integrated (R1,C1) and fed to one input of an amplification - and offset subtraction-circuit. With the output signal of this circuit the supply voltage of the circuit components may be increased in order to compensate for a degressive characteristic of the sensor (Fig. 1).

Title: Method for allocating the switching-oriented resources of a communication system for switched connections and permanent circuit connections
Inventor: STOECKL WERNER
IPC: H04Q3/545
Filed: 1993-07-26
Abstract: Method for allocating the switching-oriented resources of a communication system for switched connections and permanent circuit connections. Call duration information (vdi) is formed in the communication terminal equipment connected to a communication system for switched connections (W) whose call durations can be determined. This call duration information (vdi) is communicated to the communication system within the framework of the call setup.      In the communication system, the ending times of the switched calls are calculated after the through-connection of the switched connections (W) and those switched connections (W) are selected whose indicated call durations end lying closest to the switching deadline before the following switching deadline of a deadline permanent circuit connection (FW). Dependent on the scopes of the switching-oriented resources (WR) allocated to the selected switched (or: dialed] connections (W) and on the scopes of the switching-oriented resources (VR) required for the deadline permanent circuit connections (FV), switched connections (W) are selected from these. Their switching-oriented resources (VR) that become free are then reserved for the respectively provided, deadline permanent circuit connection (FV).

Title: An interactive communication device
Inventor: SAULSBURY ASHLEY N
IPC: H04M11/06
Filed: 1992-09-18
Abstract: Two devices are connected via a single analogue signal path such as a public telephone line in such a manner as to permit the users to talk to each other while interactively modifying an image which is presented to both users simultaneously. Each device multiplexes a reduced voice signal, e.g. from a vocoder (3), with a control signal indicative of changes to make to the image, and transmits the composite signal via a modem (4). The devices either respond to both image signals to modify the image (e.g. if they are word processors responding to key presses) or to the same selected one of the signals as determined by a protocol (e.g. if a spreadsheet is being altered by only one user at a time). Each device may be stand alone, such as incorporating a computer or facsimile machine, or an adaptor for existing such machines; it may be inserted between a telephone set and the line, or have separate audio transducers and connect to the line via a telephone set.
