Title: Polyamidopolyfunctional amines
Inventor: DOMINGUEZ RICHARD J G
IPC: C08G69/40
Filed: 1992-11-12
Abstract: Polyamidopolyfunctional amines of the following formula are described: (see figure I) where R is independently hydrogen or lower alkyl of 1 to 4 carbon atoms;    R' is an alkyl group if k is 1, or an alkylene group if k is greater than 1; where R' has 2 to 18 carbon atoms;    R" is independently lower alkylene of 2 to 4 carbon atoms;    R"' is independently straight or branched lower alkylene of 2 to 6 carbon atoms; x is independently 1 to 200; y is independently 1 to 300; z is independently 1 to 200; p is independently 2 to 11; and k is from 1 to 8; where the x and z groups may be distributed in blocks or randomly. These compositions are made by reacting a cyclic lactam with a polyether-polyamine. Incorporation. of increasing quantities of the polyetherpoly-amine did not decrease the crystalline melting point (T m) of the resulting copolymer. The polyamidopolyfunctional amines (poly(amide-ether-amide) triblock copolymers) have a relatively low modulus and retain higher use temperatures than current polyetheramide segment block copolymers. The polyamidopolyether amines may be further intercon-nected through reaction with dicarboxylic acids, esters and the like.

Title: Non-contacting transaction system
Inventor: TAIT ROBERT A R
IPC: G07B15/02
Filed: 1992-01-31
Abstract: A non-contacting transaction system as described which includes a hand-held device which contains information unique to the user and which, when actuated by the user, generates a wireless signal which is picked up by a receiver. In a preferred arrangement, the transmitter contains the user's code and has a keypad for the user to insert a personal identification number (PIN) code. The receiver is coupled via a transmission line to a local system where the user's code and PIN number and details of the purchase, received from the vendor, are registered against the user's number so that billing can be carried out subsequently. The receiver can include a means for checking and for rectifying the correctness of the code and PIN number prior to transmitting the data via the modem to the central system. Various embodiments of the invention are described; for example, the device is flexible and the PIN number could be required for all transactions to minimise fraud. Each transmitter may be provided with a terminal to allow an input to the memory for changing details of the user's account and charge number. To prove ownership of the transmitter, the owner's name, telephone number, car registration number, etc. may also be fused in the memory along with the credit card number. This information would be displayed only to the vendor who could ask the person who was using the transmitter to identify himself by name, PIN, telephone number or car registration as proof of identity.

Patent CA-2108916-A1 (CA)
Inventor: DEWEY CHARLES H
IPC: E21B17/10
Filed: 1993-10-21
Abstract: A downhole adjustable blade stabilizer is disclosed for varying the position of stabilizer blades to provide an increased ability to control the direction of drilling. The adjustable blade stabilizer includes a plurality of blades mounted in an angled track to permit axial and radial movement of the blades. The blades are driven by a piston in response to a pressure differential created by a sufficient flow of drilling mud through the stabilizer. The stabilizer blades are retracted by a spring when the pressure differential is eliminated. A positioning piston limits blade extension to a desired position. The positioning piston moves in response to a command signal, and remains in place until a new command signal is received. By maintaining the positioning piston in a locked position, the position of the blades can be reset to the prior position after the loss of pressure differential. A measuring means is provided in association with the positioning piston to enable precise measurement of blade position.

Title: Process for determining the origin of bit errors
Inventor: ARWEILER HANS-WERNER
IPC: H04L12/26
Filed: 1992-05-12
Abstract: Abstract of the Disclosure PROCESS FOR DETERMINING THE ORIGIN OF BIT ERRORS   A flow of data (DS) from a data source (1) passes to a data receiver (9) via an intermediate path (5) and a transmission path (7). Before entering the transmission path (7) the flow of data (DS) is scrambled in a predetermined manner and unscrambled in the same manner on leaving the transmission path (7). A bit error function e(n) is obtained from test data (TZ) inserted into theflow of data (DS) at the data source and evaluated according to its period length (N). A bit error (BF) occurring before scrambling goes unmultiplied to the data receiver after unscrambling, whereas a bit error (BF) occurring on the transmission path (7) is multiplied by a period length (Nv) specific to the descrambling. A comparison of this period length (Nv) with the period length (N) of the bit error function (e(n)) makes it possible to locate the origin.     Fig. 12
