Abstract: The invention relates to a system for storing a plurality of loads within a storage bay. The system comprises a pair of primary rails, and at least one pair of auxiliary rails positioned between the pair of primary rails. Carts of progressively narrowing widths are nested together at the front end of the rails. The carts are moved along the rails as loads are stored thereon. The widest cart is uppermost in the nested cart configuration and has wheels which roll along the outer edge of the pair of primary rails. The adjacent cart rolls along the inner edge of the pair of primary rails. Carts of successively decreasing width are adapted to roll on the outer edges and inner edges respectively of each successive pair of auxiliary rails. To prevent a cart from moving rearward of an adjacent wider cart, a lip may extend upwardly from the front of a cart to abut the adjacent upper cart. This system allows storage of five or more successive loads within a storage bay.

Abstract: A process for the manufacturing of thermoplastic products with a high creep strain resistance. The products are free from reinforcing additives. The process includes at least vacuum forming and/or blow moulding of a thermoplastic material such as a polyolefine. A number of product parts are manufactured from a number of preferably tube- or sheet-shaped work pieces. The work pieces are heated so that the thermoplastic material softens whereby they are given the desired shape by means of a mould and the influence of vacuum and/or pressure. The product parts produced are allowed to cool and post-shrink and are hereafter joined to a unit.

Abstract: A horn antenna is provided which is capable of operating at a plurality of separate frequencies while providing substantially equalized E and H-plane patterns for each of the separate frequencies. The antenna includes a coupling portion to permit coupling to a communication device. An inner portion is coupled to the coupling portion, and includes a first choke having a depth which extends substantially parallel to a central longitudinal axis of the antenna and a width which extends in a radial direction of the antenna. The depth and the width of the first choke are set so that the first choke will operate at the first frequency. An outer portion is coupled to the inner portion, wherein the outer portion has a maximum diameter in the radial direction which is greater than the maximum diameter in the radial direction of the inner portion. The outer portion includes a second choke which also has a depth to extend substantially parallel to the central longitudinal axis of the antenna, and a width which extends in the radial direction. The depth and the width of the second choke are greater than the depth and the width of the first choke, and are set so that the second choke will operate at the second frequency. By virtue of the fact that the depths of the chokes extend in a direction substantially parallel to the longitudinal axis of the horn, the maximum electrical aperture of the antenna can be very close in size to the maximum physical diameter.

Filed: 1999-04-30
Granted: 2009-01-06
Abstract: The present invention relates to a modified fiber product and a method of producing same. According to the method, the cellulosic raw material is formed into a fiber suspension, into which components modifying the properties of the fibers are added, subsequent to which the fibrous material is dried in connection with, for example, web forming. According to the invention, alkyl derivative of cellulose is mixed into the fiber suspension in alkaline conditions, the derivative being at least partly dissolved in water, and the derivative is allowed to be sorbed into the fibrous material prior to drying such that the sorbed cellulose derivative can not be washed off with water. The strength properties or the water retention of paper and paperboard products can be improved by using the invention.

Abstract: A disposable garment having enhanced extensibility around the leg openings is disclosed. The disposable garment has a front region, a back region and a crotch region between the front region and the back region. The disposable garment comprises a chassis and seams. The chassis comprises a topsheet, a backsheet joined with the topsheet, and an absorbent core interposed between the topsheet and the backsheet. The chassis has a central panel having side edges and a waist edge, and an ear panel extending laterally outwardly from each side edge of the central panel in the front region and the back region. The ear panel is rendered extensible to form an extensible ear. The extensible ear has a higher end edge, a lower end edge, an inner side edge, and an outer side edge. The outer side edge is non-parallel to the inner side edge, and is non-parallel to a longitudinal center line of the garment, and projects laterally outwardly proximate the lower end edge. A lateral width of the extensible ear between the inner side edge and the outer side edge is greater proximate the lower end edge than proximate the higher end edge. The seams join each ear panel along the outer side edge to a corresponding portion in the opposite region of the disposable garment so as to form one waist opening and two leg openings. The same is non-parallel to the longitudinal canter line.

Abstract: An integrated unit pump injector that includes a cam follower, unit pump, injection line and injection nozzle is pre-assembled for installation in an engine block and cylinder head.   By pre-assembling the integrated unit pump injector, the assembly can be tested for fuel leaks, injection timing and volume of fuel delivered by the pump without first installing the individual devices in an engine. Variation in fuel output, injection timing and fuel volume is reduced while engine assembly time and cost is also reduced. The integrated unit pump injector orients the pump and nozzle on parallel axes and requires that the pump bore in the block and the nozzle bore in the cylinder head also be parallel to enable the injector and pump to be fixed relative to one another prior to installation and both installed simultaneously by movement in the direction parallel to their axes.

Title: In-line retractable safety medical needle assembly
Inventor: THORNE GALE H
IPC: A61M25/06
Filed: 1999-12-14
Granted: 2006-11-28
Abstract: Disclosure of methods and apparatus providing bases for design of compact small bore medical needle retraction safety devices (10, 60', 60", 400, 600) wherein actuators (170, 630) are displaced away from slender needle sheathing bodies (40, 40', 40", 410) to initiate a needle retraction cycle for safely containing a medical needle (70) after use. Four embodiments of the instant invention are disclosed.      In one embodiment (10, 60, 60'), needle retracting energy is stored as a medical needle (70) is extended for use and is expended to retract the needle (70) into safe containment.      Other embodiments (400, 600) comprise power assist mechanisms (430, 440, 490, 510, 512, 514, 610, 640) which store energy during an initial phase of needle retraction to be used to enhance and assist needle retraction during a needle retraction completing phase. In some embodiments (60, 60"), retraction is facilitated by a pair of rigid, elongated, hingedly interconnected arms (90, 100, 90', 100'), which are further hingedly coupled to a needle hub assembly (30) and to a device body (40, 40') such that one arm (100, 100') is rotated approximately 180° to retract the needle (30) a distance greater than the length of the rotated arm (100, 100') to facilitate retraction actuation. One power assist mechanism comprises a part (192) molded as a distortable member of one of the arms (90).

Abstract: Sheets, e.g. glass sheets are secured on shipping racks using wooden lash boards or other disposable material, e.g. cardboard. The disposal of the lash boards and cardboard poses environmental waste disposal problems. The instant invention provides a solution to the problem. More particularly, in a non-limiting embodiment of the invention, a packaging restraint includes a first leg and a second leg arranged to have a generally L shaped configuration. Each leg has a compressible inner surface to engage portions of the glass sheet stack, e.g. at a corner of the stack. The compressible inner surface prevents marring of the engaged portion of the glass sheets. The outer surface of the restraint is made of a material harder than the inner surface and has an attachment thereto to capture banding when the restraint is biased against the glass sheets. The hard outer surface provides structural stability to the restraint. The restraint is small in size compared to the lash board and is reusable thereby eliminating the disposal problem.
