Title: Corrosion-resistant nail for driving into hard materials
Inventor: SARTOR DIETMAR
IPC: C22C38/38
Filed: 1992-11-25
Granted: 2002-01-15
Abstract: Nails are driven into hard receiving materials such as concrete, rock, metal and the like by explosive powder charge operated setting tools. To achieve the high mechanical strength required for such nails, the nails are formed of two parts, one a shank and the other a head fitted auto the shank. While the head consists is formed of a deformable corrosion resistant steel, the shank is formed of an austenitic steel alloyed with nitrogen having a very high mechanical strength. The steel forming the shank can only be shaped to a very limited extent, whereby a narrow flange is provided on the rear end of the shank. A disk fitted on the shank serves as a guide for the nails during the driving operation.

Title: Ink jet recording means and packaging therefor
Inventor: YANO KENTARO
IPC: B41J2/175
Filed: 1992-12-16
Granted: 1997-12-09
Abstract: The present invention is to improve the storage performance of the recording head in the prolonged storage such as in the course of distribution, and to eliminate limitation and to increase freedom in the handling in the distribution of the recording head.  There is provided ink jet recording means in which a recording head unit and an ink tank unit, containing ink for supply to the recording head unit are integrally combined at the use, but the ink tank unit is separately replaceable when required, wherein the recording head unit contains, prior to the initial use, ink for storage which is different from the ink for recording.  This configuration improves the storage performance of the recording head, eliminates limitation in the distribution and increases freedom in handling.

Title: Sensor, system and method for determining z-directional properties of a sheet
Inventor: CRESSON THIERRY M
IPC: G01B7/00
Filed: 1991-12-20
Granted: 2001-10-23
Abstract: A sensor (12) system and method for determining the various Z-directional properties of a sheet (14) by measuring the ca-liper of a moving sheet (14) of material at a plurality of pressures. The invention employs a caliper gauge (10) and a set of pres-sure transducers (not shown) that can measure and send signals indicative of the caliper as well as pressures exerted on the sheet (14). The signals are then digitized by an analog-to-digital converter (not shown) and sent to a computer (30). The computer (30) uses the compressibility data to construct a compression stress-strain diagram where the slope of the curve in the linear region of the region of the curve is defined as the compression modulus of elasticity which can be empirically correlated to the tensile mod-ulus of elasticity for various grades of paper. The tensile modulus of elasticity can hen be used in various formulas to determine other Z-directional physical properties of the sheet (14) such as tensile strength, extensional stiffness and Scott bonding.

Abstract: In the windscreen-wiper system proposed, the wiper blade (5) is rotatably mounted on a telescopically extendable part (3) of the wiper arm and can be moved, lying substantially flat, laterally over the vehicle windscreen (1). The drive producing the pivoting motion of the wiper arm is transmitted to the wiper arm via two cable lines (7, 15); the first of which (7) causes the wiper blade (5) to rotate when its two lengths of cable (8, 9) move relative to each other. The second cable line (15) is used to alter the length of the wiper blade. It consists of a payingout cable (16) which passes over a first pulley (18) driven by the wiper-arm pivoting-motion drive and over a second pulley (19) mounted on the lower part (2) of the wiper arm; and is attached to the telescopic part (3) of the wiper arm; and a pulling-in cable (17) which is made up of both the lengths of cable (8, 9) and passes from the pulley (10) mounted on the telescopic part (3) of the wiper arm back to the driven pulley (18).

Abstract: An arrangement for pooling service circuits so that they become available to a plurality of switching systems in a telecommunications network. Aregional control node receives a request for a service circuit to be connected to a call. The regional control node maintains the availability status of the service circuits in a pool for the region. In response to a request for a service circuit, the regional control node selects an appropriate circuit and transmits order to the switches and the circuit to establish the proper connections among these units in order to associate the service circuit with the requesting call. Advantageously, such an arrangement permits a large pool of individually expensive service circuits to serve a largenumber of switching systems, thus, increasing the efficiency of utilization of these service circuits. The arrangement is also used for controlling the allocation oftransmission resources to any call, thus optimizing the use of the regional transmission resources.

Title: Self-optimizing detergent controller
Inventor: BRADY DANIEL F
IPC: D06F33/37
Filed: 1992-10-26
Granted: 1999-07-20
Abstract: An apparatus and method for programming a detergent controller (12) to vary the detergent concentration set point (14) according to the time of day and to achieve detergent concentration levels quickly without incurring overshoot. Thus, the present invention insures that the warewashing machine is operated at optimum efficiency and cost. To vary the set-point according to the time of day, the invention combines the features of a microprocessor, a clock and a controller into one unit. The user enters the time setting (16) and set point into the controller (12). The microprocessor (10) then compares the real-time clock signal with the user time settings and outputs an appropriate set-point value from the microprocessor (10) to the controller (12). To achieve detergent concentration levels quickly without incurring overshoot, the controller (12) senses the detergent concentration and dispenses the proper detergent level to the warewashing machine according to a predetermined detergent feed time based on the previous response time and the programmed set-point (14). Thus, the controller (12) can change the response function if and when conditions change.

Granted: 2005-11-01
Abstract: An animal cell is co-transfected with both a recombinant DNA viral vector which bears a promoter, a recombinase gene and a poly(A) sequence and a recombinant DNA viral vector which bears two recombinase-recongnizing sequences and which further bears an origin of replication, a promoter, a foreign gene and a poly(A) sequence, each of which is located between the two recombinase-recongnizing sequences. Thereafter, in the co-transfected animal cell, a DNA fragment containing the origin of replication, promoter, foreign gene and poly(A) sequence is excised from the vector by the action of a recombinase expressed in the another vector.      The DNA fragment forms a circular DNA molecule which autonomously replicates in the co-transfected animal cell due to the origin of replication, whereby the foreign gene is continuously expressed.      Accordingly, the combination of the above two DNA viral vectors wherein a gene which is defective in patients is used as the foreign gene is quite useful especially for the treatment of the patient with hereditary diseases.
