Title: Fluid Powered Cutting Tool
Inventor: WELLS ANDREW J
IPC: B26B7/00
Filed: 1993-03-25
Abstract: A balanced essentially vibration-free hand-grippable fluid powered reciprocating blade cutting tool intended primarily for cutting poultry, fish and meat for processing.  The tool includes a hollow handle which functions as a motor housing.  Fitting means are provided for connecting the housing to a source of fluid under pressure and for exhausting fluid from the housing.  A reciprocable cutting blade extends forwardly from the handle.  A fluid actuated motor within the handle housing includes a pair of aligned piston assemblies of approximately equal weight.  The pistons are reciprocable in opposite directions.  The cutting blade is secured to one of these pistons.    A control valve and fluid flow passages within the housing and associated with the fluid inlet fitting permits fluid to be directed alternately to the inner and outer sides of the pistons for causing the pistons to alternately move toward one another and away from one another.  Manually operable trigger means control the flow of fluid into the housing.  The angle of the cutting blade relative to the handle is variable to further reduce fatigue and other problems associated with rotation of the wrist, which is a contributing cause of carpal tunnel syndrome.

Title: Oligodeoxynucleotides and oligonucleotides useful as decoys for proteins which selectively bind to defined dna sequences
Inventor: CHU BARBARA C F
IPC: A61P31/12
Filed: 1992-04-17
Abstract: Improved DNA structures are disclosed which contain target sequences which bind to control proteins (such as the CREB protein).  The structures of the present invention are stable to degradation, and are effective as decoys for control proteins, making it possible to modulate the transcriptional control normally exerted by such control proteins. In addition, there is provided a method to reversibly crosslink oligonucleotides to polypeptides which recognize the oligonucleotide sequence. This method involves synthesizing DNA structures as described above, wherein one or more phosphorothioate diester linkages are incorporated into the resulting oligonucleotide, allowing the phosphorothioate diester-containing oligonucleotide to bind to polypeptides which recognize the sequence of said oligonucleotide, then contacting the polypeptide-bound oligonucleotide with a transition metal reagent.

Title: Pneumatic plantar arch support
Inventor: NEACSU VIOREL I
IPC: A43B7/14
Filed: 1994-02-22
Abstract: The plantar arch support, as a component of the shoe, is conceived as having an orthopedic role, mainly for children as users or with a view to improve the best distribution of the body weight on the support surface of the foot, in case of all users.  The use of the plantar arch support results in an increased contact surface between foot and insole and consequently more comfortable to wear.  The use of the rigid arch support can cause a partial or total malfunction of the middle segment of the foot, i.e. the longitudinal and transversal plantar arch, which can cause an atrophy of the complex system formed by bones, joints and muscles.  When using semirigid plantar arch support, with a certain degree of elasticity, the contact between thes supports and the foot is obtained by copying it, a difficult and expensive thing to do, that has to be done for each type of foot; if this contact is approximative, the function of the support becomes ineffective.  The object of the present invention is constituted of the pneumatic plantar arch support, materialized in the form of a cushion with a specially-designed shape, using sheets of polyethylene, pvc, rubber, airproof textiles or other kinds of elastic-plastic, thermo-weldable, vulcanizable materials or materials that can form airproof joinings, filled with air or other gaseous mixtures.  Depending on the use of the plantar arch support, for children or adults' shoes, for casual or sports wear, etc, the pneumatic cushion of the support can be filled with a smaller or bigger quantity of air and the inner pressure of the air will vary accordingly. Thus the role of sustaining the foot arches as well as that of increasing the contact surface between the foot and the insole can be decreased or increased from the very moment of its fabrication.  The main characteristic of the pneumatic plantar arch support, making it different from all the other type of supports known until now, is its quality to change its shape according to the foot shape of each individual. While wearing the pneumatic plantar arch support, it changes its form and specific pressure of each point of its surface, so that the support of the foot arch and the increased contact between the foot and the insole is at its maximum all the time: with both feet on the floor or in the case of a unilateral contact with the floor, standing on a single foot.  At the same time the air quantity in the pneumatic plantar arch support moves in all directions under the pressure of the body weight; by massaging the plantar surface, it also has a benificial effect on the general state of health of its wearers.

Title: Gaming device providing high security communications with a remote station
Inventor: MARTIN JOHN R
IPC: G06Q50/34
Filed: 1993-02-12
Abstract: A gaming device (10) is shown having one printed circuit board (42) that includes a game control processor (20); at least one memory storing game operation information (22. 24); and a light transmitter (36) for transmitting encoded information representing selected game operation information that is stored in the memory. The gaming device (10) also includes a communication printed circuit board (44) that has a light receiver (40) for receiving light encoded information from the light transmitter (36); at least one memory (52,54) for storing game operation information as represented by the light encoded information received by the light receiver (40); and a communication controller (50) that allows communication between the gaming device (10) and a remote station (18). Because the light transmitter (36) can transmit information to the communication board (44) but cannot receive information therefrom, communications  between the gaming device (10) and a remote station (18) are allowed without compromising the integrity or security of the operations of the gaming device (10).

Title: Short Radius Culvert Sections
Inventor: MCCAVOUR THOMAS C
IPC: E01F5/00
Filed: 1994-10-14
Abstract: Soil/metal supporting structures commonly include panel sections having a short radius of curvature in the range of 750 mm to 2,500 mm. In such soil metal supporting structures the panels are of heavy gauge in the range of 2 mm to 10 mm thickness.  Usually, expensive tooling and forming techniques are required to cold form the heavy gauge material into a curved shaped having such short radius. Such expensive techniques have been eliminated by this invention by virtue of the improvements comprising:      a) the panels have a high degree of ductility before being cold formed, such high degree of ductility being determined by a ratio of specified minimum yield strength to specified minimum tensile strength equal to or less than 0.8; b) the panels are cold formed with cross-corrugations in each of the inside ridges of the longitudinally formed corrugations of the panel, the cross-corrugations are sinusoidal and cross section and allow the cold forming of a short radius panel on a consistent basis without dislodging panel shape to facilitate thereby interconnection of the panels for the structure; c) the cross-corrugations have a depth in the range of 4 mm to 12 mm and a pitch of 40 mm to 70 mm; and d) the cold formed panels of short radius by virtue of the sinusoidal shaped cross-corrugations provide a finished panel with marginal increase in ductility, thereby allowing for either plastic or elastic analysis in providing the soil/metal supporting structure.
