Abstract: An improved system is disclosed for detecting invalid transaction cards at remote transaction terminals. The system includes providing each terminal with a master table having data corresponding to invalid cards. The data in the master table is less than the actual account numbers of the invalid cards. By using a compressed version of the data, the file can be shortened to facilitate storage and transmission. The compressed data file is arranged such that when an invalid card is presented, it will be identified and routed on for further processing. In the preferred embodiment, the probability that a valid card will be identified as potentially invalid is on the order of one to three percent. During each transaction, the master table is supplemented with information about the account number of the transaction card presented for the purchase. In this manner, any subsequent use of the card will be routed for additional processing. A scheme for compensating for data transmission errors is used to reduce the possibility that information about invalid cards is not lost when the master file is distributed

Abstract: A data encoding system and method for selectively encoding, demodulating, synchronizing a demodulator uses the following d=7, k=2 code: 
               DATA BITS   CODE WORDS     00   000X     01   0100     10   100X     011   10000X     111   100100     0000   1000000X                        where X is a ONE if the last two bits of the preceding code word are both ZEROS and a ZERO otherwise, and the right-most bits are the first in time. The system encodes the data by encoding the first four bits of data to an eight-bit code word if the bits are all ZEROS and the last two bits of the previous code word are in a predetermined pattern. If the first four bits are not ZEROS the system encodes the first three data bits to form a six-bit code word if the first two bits are both ONES. Otherwise, the system encodes the first two data bits to form a four-bit code word. The system selects the code word which preserves the code limited run length.

Abstract: A drilling tool is followed by a casing tube (11) down the drilled hole. The mouth of the casing tube (11) centers rotatably a guide member (10) which receives rotation and impact energy via the interior of the casing tube (11). A drill bit (20) consists integrally of an axially protruding pilot portion (23), a sidewise projecting eccentric portion (22) and a rear shaft (21). The shaft (21) extends pivotally and axially movably into an eccentrically disposed bore (24) in the guide member (10). Axially spaced peripheral end grooves (30,32) extend in opposite direction from an axial cam groove (31) on the shaft (21) and are engaged by a follo­wer (28) in the guide member (10) defining positively the axial and angular movability and positions thereof relative to the drill bit (20). In the forward end groove (32) the follower (28) maintains the drill bit (20) axially in dril­ling position adjacent to the guide member (10) with the eccentric portion (22) protruding to drill a hole larger than the casing tube (11). In an intermediate position 90° away from the drilling position, the follower (28) enters the cam groove (31) whereby the guide member (10) becomes axially movable the distance between the end grooves (30,32). In a rear axial position the guide member (10) by a continued 90° turn brings the follower (28) into the rear end groove (30) to axially define the retracted position of the drill bit (20), wherein it can be raised or lowered freely through the casing tube (11).

Abstract: The tension element consists of two parallel wire cable sections 3, especially sections of a wire cable 1 which is bent to form a loop, and of a driver part 2 which is pressed against it. In order to achieve a high withdrawal resistance for the wire cable sections 3 with low production costs and a space-saving method of construction for the driver part 2, it is provided that the driver part 2 is a sheet-metal part, which is originally flat and is subsequently bent at least partially in the form of a sleeve, the sleeve-shaped section 2a of the driver part 2 having notches 6 running at right angles to the tension direction. Particularly high withdrawal resistances can be achieved if there is at least one notch 6 on one side of the sleeve-shaped section 2a of the driver part 2 and in each case a further notch 6 on the opposite side, in front of and behind the point at which the first-mentioned notch 6 acts. Finally, the withdrawal resistances can be further increased by providing recesses, such as grooves 9 or holes 10, for the partial penetration of the wire cable sections 3, opposite the notches 6 on the inside of the sleeve-shaped section 2a. <IMAGE>

Abstract: A subscriber line interface circuit (32) provides regulated current to a telephone subscriber (14) in an improved manner by reducing the amount of power required to operate while maintaining a constant current source. The current to the telephone subscriber (14) flows through a switching transistor (92, Fig. 3), and inductive storage element (98, Fig. 3), sensing resistors (54, 56) and a hybrid transformer (38). The desired operating characteristic is obtained by cycling the switching transistor (92). The switching transistor (92) is cycled on at a preset interval causing the telephone subscriber current to flow from the switching transistor. The switching transistor is cycled off in response to an increase in the telephone subscriber current as sensed by the sensing resistors (54, 56) thereby causing the current to flow from the inductive storage element (38). A current sensor (60) coupled to the sensing resistors (54, 56) supplies a current level signal SUMSIG to the switch-mode current source (52) that includes the transistor (92)2 and the inductive storage element (38). Saturation of the transformer (38) is prevented by regulated opposing current supplied by a source (80) controlled by the SUMSIG signal.

Abstract: An ion beam implantation system (10). An ion beam (14) is controllably deflected from an initial trajectory as it passes through spaced parallel plates (26, 28) that are biased by a control circuit. Once deflected, the ion beam enters an electrostatic lens (30) that redeflects the once deflected ion beam. When the beam exits the lens, it moves along a trajectory that impacts a workpiece. By controlled deflection of the beam, multiple parallel beam paths result, all of which input the workpiece at a uniform impact angle.
