Abstract: A vehicle washing apparatus includes a side track extending along a crashing bay. A gantry is supported for reciprocal motion along the side track by a gantry motor.  Sensors detect the front and rear ends of the vehicle to control movement of the gentry. A retractable carriage extends from the gantry across the washing bay under the control of a carriage motor and a vehicle width sensor. The carriage rotatably supports a spray bar for discharging cleaning fluid. A  motor rotates the spray bar to sweep around corners of the vehicle. A cam plate and engagement roller index the spray bar orientation, while limiting spray bar rotation to a single direction. A wheel guide receives the front left vehicle wheel.

Title: Method of storing a ligand in a releasable containment means and method of releasing a ligand therefrom
Inventor: FARMILO A JAMES
IPC: G01N1/30
Filed: 1994-02-03
Granted: 2009-04-21
Abstract: There is disclosed an automated apparatus and process for immunocytochemical staining of biological materials using ligand pairing. The apparatus includes an array of sample cells interconnected with reagent supply and drainage lines. Each cell encloses a fluid chamber into which a sample substrate is inserted. The face of the substrate onto which a biological sample is mounted faces into a fluid well. The cell includes a cell head having a chamber to receive therein a solid support matrix releasably containing a ligand to be contacted with the sample. The chamber in the cell head is in flow communication with the fluid well so that when the ligand is released from the matrix it flaws into the fluid well thereby contacting the mounted biological sample. The ligand support matrix may be gelatin or wax. The cell body and cell head are differentially heated or cooled so that the mounted sample may be held at the preferred temperature for the reaction of interest and the call head may be heated to a temperature sufficient to cause thermal degradation of the matrix to effect release of the ligand. Control electronics is provided for sensing and controlling the temperature of the various cell parts and for programmable control of reagent supply to the cells. 19

Abstract: The present invention refers to an arrangement for the production of blow-molded hollow bodies from plastic with a blow molding machine, wherein a cooling medium can be blown via a conduit into a blow mold respectively into the hollow body for blowing up and cooling of the blow-molded hollow body. For improvement of cooling the interior of the hollow body within the blow mold, a closed conduit system is provided, in which the cooling medium circulates and is kept at an elevated pressure level and is cooled by means of a heat exchanger. Thereby, a higher yield of piece per time is realized at lower production cost. The closed cooling medium circulation system can be essentially retrofitted to all blow molding machine in order to raise efficiency.

Abstract: A server is implemented with a modified file open action, which, when a user performs the modified open, initially opens a file without locking the file. When a user indicates (either explicitly or implicitly) that the user is attempting to or intending to open the file, the file can then be locked for editing. In this way, the default action when a user requests a file is to open the file without denying other users access to the file. Then, when the user indicates that editing should occur, the lock for the file is obtained.

Abstract: A bow-forming ribbon assembly has a decorative flexible ribbon member and a drawstring connected loosely to the ribbon at points along its length by relatively stiff retainer members. Each retainer member extends generally transversely across the ribbon member, and each is inclined with respect to the transverse direction at an angle. Each retainer member is inclined at an angle different from that of an adjacent retainer member. Decorative arms having adornments are mounted adjacent at least some of the retainer members. On forming the ribbon into a bow by pulling the drawstring relative to the ribbon member, the inclined retainer members tend to skew the adjacent loops or segments of the bow relative to one another, as well as the decorative arms so that the loops and the arms are distributed at various angles around the axis of the bow, thereby providing a bow of great visual interest.

Abstract: L'invention concerne un fil transporteur (2) avec des éléments transporteurs à forme de disques (8), destiné à être utilisé dans des systèmes de transporteurs à tube sans fin. Le fil (2) consiste en un certain nombre de brins torsadés (4) chacun formé de fils fins ou de fibres fines, et comprend une gaine extérieure (6) à laquelle les éléments transporteurs (8) sont fixés directement par moulage par injection. Cette gaine extérieure (6) consiste en un polymère dont la température de fusion est inférieure à la température de fusion du matériau plastique à partir duquel les éléments transporteurs sont moulés par injection. Le fil (3) par ex. est fabriqué en tant que fil équilibré (neutre en ce qui concerne la torsion) consistant en au moins trois brins chacun constitué de fibres synthétiques très fines traitées individuellement au niveau de leur surface avec un polymère, ce qui permet d'obtenir des fibres possédant une grande résistance à l'usure par pliage et une bonne adhérence à la gaine extérieure (6) constituée d'un polymère. Le fait que la température de fusion du matériau à forme de disque est supérieure à la température de fusion du matériau de gaine a pour conséquence un ramollissement local de la gaine extérieure au niveau des éléments transporteurs, de façon qu'une connexion optimale soit établie entre les éléments transporteurs et le fil par l'intermédiaire de la gaine extérieure.
