Title: Message transmission system
Inventor: RITTER RUDOLF
IPC: H04W4/14
Filed: 1995-06-20
Granted: 2004-04-06
Abstract: The system for transmitting messages is used in a mo- bile radio telephone network (1) having a number of termi- nals (4, 9). The terminals may be either permanently allo- cated to a specific user or allocated to a specific user by means of a chip card insertable in the terminal. At least two terminals can enter into voice or data communication with one another in the mobile radio telephone network. The mobile radio telephone network comprises at least one center (8) for controlling the message transmission, each message being a data communication in which data telegrams contain- ing a standardized data header are exchanged. For process- ing special services according to a special procedure acces- sible only to certain authorized subscribers, the data tele- gram comprises an identification code in addition to the standardized data header. A central unit (10) associated with the center and at least some of the terminals have means for generating data telegrams provided with the iden- tification code. The central unit for the special services, as well as authorized terminals or authorized chip cards, are equipped with a filter (12.1, 12.2), preferably a soft- ware filter, for recognizing the identification code. The possibility is thus offered not only of transmitting any de- sired bit streams in transparent mode according to GSM Phase 2, but also of sending data and executable instructions to or receiving them from authorized subscribers without having to change internationally established standards.

Patent CA-2172001-C (CA)
Title: Luer-type connector
Inventor: APPLING WILLIAM M
IPC: A61M39/10
Filed: 1996-03-18
Granted: 2007-09-11
Abstract: A luer-type adapter has a dual instead of a single set of engaging screw threads. A proximal and a distal screw thread on the hub engage proximal and distal screw threads on the collar of the connector to provide at least twice the engaging or sealing force between the tapered surfaces of the stem and hub which are forced together by rotating the collar relative to the hub to engage the two sets of threads. The diameters of the engaging distal screw threads have to be sufficiently great so that the proximal screw thread on the hub can pass under the distal screw thread on the collar in order to effect proximal as well as distal engagement. An O-ring mounted on an untapered distal segment of the stem engages an untapered inner hub surface to provide additional sealing force which is particularly useful where gas is being provided through the adapter.

Title: Releasable fluid hose loading arm system
Inventor: KONCSEK SANDOR
IPC: F16L3/01
Filed: 1997-08-01
Granted: 2004-10-19
Abstract: A system 10 fluidly connects a bulkhead B to a portable. transport using a flexible fill line or liquid hose LH. The system includes a coupling 12 for separating the liquid hose LH from the bulkhead B during an inadvertent pull-away. An arm 24 is pivotally supported by the bulkhead B, and a support plate 36 is supported at the upper end of the arm 24. A release disk 50 is normally supported by the plate 36, and in turn supports a saddle 42 for supporting the liquid hose LH. Three circumferentially spaced pins 38 function as retaining members to support a release disk 50 on the plate 36. The components thus function to prevent the discharge end of the hose from dropping onto the ground. During a pull-away, at least one of the coil springs 64 associated with each release pin is compressed, thereby releasing the disk 50 and allowing both the saddle 42 and the liquid hose LH to become disconnected from the arm 24. The continued pull-away then separates the coupling 12, thereby preventing fluid from escaping from the bulkhead.

Patent CA-2217764-C (CA)
Inventor: MERCER GEORGE E
IPC: G06Q30/02
Filed: 1997-02-14
Granted: 2002-01-22
Abstract: A system for generating authorization codes, such as personal identification numbers, at the point of distribution of certificates of value on which the authorization codes are to be printed or otherwise encoded. Because the authorization codes are generated in real time, there is no need to store and safeguard an inventory of preprinted certificates, or even an inventory of activated authorization codes. The principles of the invention apply both to systems for generating incentive award certificates and to systems for generating purchased certificates of value. The incentive awards or certificates of value are tokens of prepayment for a service, such as long-distance telephone service or other service. The authorization codes generated for inclusion with the value certificates are unique and seemingly random. They are generated by taking a non-random unique code, such as a sequence code, and encrypting it to obtain seemingly random, but unique, authorization codes. Because each authorization code is not generated until immediately prior to distribution of the certificate with which the code is associated, security and other problems pertaining to preprinted certificates and cards are eliminated.
