Abstract: A method for cutting a portion of a flat or outside animal round into a plurality of meat products including steaks having substantially enhanced value comprises removing substantially all of a fat layer from the exterior surface of the portion of the animal round. A natural seam on the muscle is located and a cut is made along the seam to divide the portion of the beef round into at least two separate portions, a first portion having coarse grains extending in multiple directions and a second portion having generally parallel grains. Substantially all of the cartilage, membrane, fat, and other non-meat tissue is removed from the outside of the first portion. Substantially all of the cartilage, membrane, fat and other non-meat tissue is also removed from the outside of the second portion. The second portion is tenderized and is then cut across the grain in a direction generally parallel to natural seam into a plurality of steaks, each steak being very low in fat content and of relatively high economic value.

Abstract: A self-propelled saw for cutting green or uncured concrete having a frame with rear drive wheels and adjustable front wheels is provided. The saw has a handle for guiding it along the desired path to be cut in the concrete and a drive motor for the saw blade and the rear wheels mounted on the frame. Motor or pump driven means interconnecting the handle and front wheels raise and lower the front wheels at the control of the operator to remove or insert the saw blade into the concrete to be cut. A track assembly, including a pair of parallel tracks moves with the frame as the saw blade is inserted into the concrete and the tracks engage and roll along the surface of the concrete to support the surf ace adjacent the saw blade as the concrete is being cut.

Abstract: A multiple lumen catheter assembly and methods for inserting the same are provided. The assembly includes a splittable membrane joining a first catheter and a second catheter for allowing the catheters to be at least partially longitudinally split from each other. Each catheter has at least one lumen extending longitudinally through the catheter. One method for inserting the assembly includes making an incision near the area to be catheterized, at least partially splitting the distal end regions of the catheters from each other by splitting apart the splittable membrane, and inserting the distal end regions of the catheters in a juxtaposed relation through the incision and into the area to be catheterized. In another method, the catheters are first tunnelled subcutaneously by pulling the distal end regions of the catheters in the assembly through a tunnel and outwardly from the tunnel near the area to be catheterized, leaving proximal end regions at least partially within the tunnel.

Abstract: A safety system (10) for a materials handling device, for example fork lift truck, conveyor, comprises a sensing head (11) linked to a pressurization control unit (12). The sensing head (11) monitors the level of explosive vapors in proximity to the device relative to low explosive level (LEL). When a level of explosive vapors of below 25% LEL are detected, the pressurization control unit (12) maintains the supply of an inert gas for a supply (13) to at least one sealed enclosure which encloses any hazardous components in the device at substantially atmospheric pressure. When a level of explosive vapors above 25% LEL is detected, the pressurization control device (12) is operable to increase the supply of inert gas to the enclosure (14) to being the pressure in the enclosure (14) to greater than atmospheric pressure.

Abstract: Magnetic cards are formed by plural, coadjoining, generally planar, parallel layers. Outermost layers form outer sides of each card. At least a first visible image is provided on a first of the outer sides. The card includes a generally planar, permanently magnetized layer formed by one or more permanently magnetizable planar components that are fixedly positioned preferably within a frame between the opaque outer sides or a magnetizable material layer only -part of which has been selectively permanently magnetized. The permanently magnetized layer or permanently magnetized portion of a larger, magnetizable layer has a predetermined configuration which is related at least in informational content to the first visible image. A silhouette of the predetermined configuration can be magnetically reproduced by placing a card on a magnetically actuated fluid display panel.

Abstract: A method and apparatus for automatically transferring a predetermined quantity of a sterile liquid to a vial containing a dry medicament for hydrating the medicament and then transferring the hydrated medicament to a container. To hydrate the medicament, a needle is positioned through a vial septum of the vial and an artificial sensor senses when the needle has been positioned through the vial septum and actuates a pump to transfer a predetermined quantity of sterile liquid into the vial. The needle is then removed from the vial septum and the vial is shaken to mix the liquid and medicament. To transfer the hydrated medicament to a container, another needle is positioned through the vial septum. An artificial sensor senses when the needle has been positioned through the vial septum and actuates the pump to transfer the hydrated medicament to the container.

Abstract: The invention provides probes and primers for amplifying certain regions of genes for structural proteins of cartilage and methods for detecting mutations in these genes isolated from the nucleic acid of cells suspected of exhibiting mutant structural protein gene expression or having mutant structural protein genes. The invention also provides methods for determining a genetic predisposition for a disease that alters the structure or function of cartilage because of a mutation in a gene for a structural protein of cartilage in a mammal.

Abstract: The invention relates to a compositions and methods for transfection of cells, particularly airway epithelial cells, with DNA complexed to polylysine substituted with glycosyl residues.

Abstract: A limb guard serves to protect a part of a limb from an external impact force and includes an elongate pad member, an elongate sheet layer mounted on the pad member to form an accommodation space between the elongate sheet layer and the elongate pad member, and a one-piece resilient impact absorbing member. The shock absorbing member is inserted in the accommodation space, and has a longitudinally extending central section of a first thickness adapted to resist and consequently absorb the external impact force applied thereon, and two lateral wing sections which are integrally formed with and which extend laterally from two longitudinal edges of the central section.

Abstract: An apparatus (1) serves for cleaning surfaces on boards, for instance, and has a cleaning device (2) which is circumferentially continuous and has an upper strand (2) and a lower strand (4) and two guide pulleys (5, 6) in between. The one strand is the cleaning strand which is held by a guide (8) and is pressed onto the surface to be cleaned. A carrier belt (7) is recessed or flattened in some regions of at least one longitudinal side and is therefore narrower in relation to the rest of its longitudinal area. At least one part (8a) at the entrance end of the guide (8) as considered in the feed direction of the cleaning strand, is deflectable or flexible outwardly from the feed direction and can thereby be applied to the inside (7a) of the carrier belt (7). The guide (8) has a substantially C-shaped cross section accommodating the entire width of the carrier belt (7).

Abstract: A subcutaneous tunnelling device, a dilator and a method of forming a subcutaneous tunnel are provided. The device includes a trocar having a front end with a point configured for piercing skin, and a dilator which has a front end removably attached to the rear end of the trocar. The dilator is for dilating a section of a subcutaneous tunnel and includes a dilating section having a maximum diameter sized for dilating an interior surface of a subcutaneous tunnel for seating a catheter stabilizing cuff in the subcutaneous tunnel. The method of forming a subcutaneous tunnel includes the steps of inserting a trocar through a first location on a cutaneous surface and moving the trocar through subcutaneous tissue to form a subcutaneous tunnel. The trocar is at least partially removed and a front end of a dilator is attached to the trocar. A section of the tunnel is dilated by moving the dilator partially through the tunnel until the front end of the dilator reaches a first subcutaneous location in the tunnel.
