Abstract: A golf ball washer includes a housing having interior walls defining an interior cavity and a cylindrical lip defining an access opening. The cylindrical lip has exterior threads. Abrasive ball cleaning medium lines the interior walls of the interior cavity. A plunger is disposed within the interior cavity of the housing. The plunger has a first end and a second end. The plunger is movable between an extended position and a retracted position. In the extended position the first end of the plunger telescopically extends from the access opening of the housing. In the retracted position the plunger is confined within the housing. The plunger has a golf ball receiving aperture extending therethrough. The golf ball receiving aperture protrudes from the access opening when the plunger is in the extended position, such that a golf ball can be inserted in the golf ball receiving aperture. A top cap is rotatably mounted to the first end of the plunger. The top cap has a depending annular skirt with interior threads. The interior threads on the annular skirt of the top cap mate with the exterior threads on the cylindrical lip of the housing when the top cap is rotated relative to the plunger with the plunger is in the retracted position.

Title: Brake for pressureless exit channel, coin sorter
Inventor: RASMUSSEN JAMES M
IPC: G07D3/12
Filed: 1994-09-13
Granted: 1999-05-11
Abstract: The present invention is a coin sorter apparatus for sorting a group of mixed coins by denomination and immediately terminating the sorting process in response to a predetermined operating condition, such as the filing of a coin receptacle with a predetermined number of coins. Sorting is provided by a stationary sorting head and a rotatable disc positioned sufficiently proximate to one another so that when the group of mixed coins are dropped into the center opening of the stationary sorting head, they are rotated by the rotating disc and guided by the sorting head on an outward spiral sorting path to exit channels along the periphery of the stationary sorting head.  Each of the exit channels acts as an exit chute for a particular coin denomination by releasing pressure on that particular coin and freeing the coin to move outwardly along the exit channel and exit in to a coin receptacle.  At the moment of the predetermined operating condition, a braking mechanism immediately stops the rotation of the rotatable disc, and the coins within an exit channel exit through the exit channel due to the inertia of the coins.

Title: Light source intensity control device
Inventor: BENNETT ROBERT E
IPC: H01S5/00
Filed: 1994-12-08
Granted: 2000-02-08
Abstract: A light source device having a controlled current source that maintains a constant intensity of light from the source during changes in light source temperature, particularly at warm-up.  The light source is heated to speed up warm-up and to maintain constant temperature of the source during operation under varying ambient temperatures. Control of the current to the light source is determined by the temperature profile circuit with signals via a temperature signal conditioner from a temperature sensor proximate to the light source.  Control of the heater is ultimately dictated by temperature sensor signals.

Title: Resines chromatographiques hydrophobes a groupes ionisables
Inventor: BURTON SIMON C
IPC: C07K1/20
Filed: 1995-06-23
Granted: 2006-08-01
Abstract: L'invention concerne des résines, des complexes de résines-protéines/peptides et des procédés de purification de protéines et de peptides à l'aide desdites résines. Les résines de l'invention sont utiles pour la liaison d'une protéine ou d'un peptide sélectionné, notamment provenant d'un milieu aqueux tel qu'un bouillon de fermentation, par interaction hydrophobe entre la résine et la protéine ou le peptide sélectionné. La résine est caractérisée par le fait qu'elle contient des ligands ionisables et/ou présente des fonctionalités non chargées au pH de liaison de la protéine ou du peptide cible, facilitant ainsi les interactions hydrophobes, et chargées au pH de désorbtion, interrompant ainsi l'interaction hydrophobe établie entre la résine et la protéine ou le peptide cible. L'invention concerne plus particulièrement l'utilisation des résines décrites dans la purification de produits enzymatiques recombinés tels que des protéases, par exemple, la chimosine ou la subtilisine.

Title: Bouchon a compensation de pression pour une tete de production horizontale de puits sous-marin
Inventor: EDWARDS JEFFREY CHARLES
IPC: E21B33/12
Filed: 1995-08-31
Granted: 2003-05-27
Abstract: Bouchon à compensation de pression à utiliser avec des têtes de production de puits sous-marins, dans lequel un réservoir de fluide de compression est situé dans une cavité dans une tête de production (10) horizontale, ce qui permet à des modifications du volume induites par la température d'être absorbées par le fluide de compression sans qu'il en résulte une augmentation significative de la pression. On y parvient en plaçant dans la cavité un appareil (80) de compensation de pression, ledit appareil comprenant un logement (82) avec un piston flottant (86) dans une chambre (84). La face inférieure (96) de la chambre est exposée à du fluide de compression sous forme d'un gaz inerte, tel que de l'azote, qui est pré-contraint à la surface à la pression hydrostatique appropriée des fonds marins. Le volume de gaz piégé entre la face inférieure du piston et la face inférieure du cylindre forme le réservoir de gaz (94). Un cylindre de compensation peut être fixé à la partie supérieure du bouchon inférieur (70) et installé et enlevé en même temps que le bouchon, ce qui réduit le nombre d'interventions. Lorsque le bouchon inférieur (70) est posé et que la cavité est isolée, tout changement de volume du liquide dû à une augmentation de température lorsque le puits est en production est compensé par le mouvement du piston (86) et la dilatation et la compression du gaz inerte qui en résulte, ce qui maintient la pression dans la cavité environ à la pression hydrostatique. Il en résulte que toute augmentation de pression est limitée ou prévenue et que la pression à l'intérieur de la tête de production est conforme à la pression de conception du bouchon ou de la tête de production, ce qui permet de réduire à un minimum tout dommage aux bouchons ou à la tête de production.

Abstract: An office chair seat carrier or support includes a seat platform earner and a back rest carrier pivotally connected about parallel rotatable axes to a carrier part. A stack of lamellar disks is pivotally connected between the earner part, seat platform carrier, and back rest carrier for holding the carriers in place by frictional contact. The stack of lamellar disks is linked with a holding member rigidly attached to the carrier part. Frictional contact is established by activating an actuator lever which slides a clamping member against the stack of lamellar disks. The clamping member applies a lateral clamping force upon the stack of lamellar disks forcing the disks together. Frictional contact is broken only after the actuator lever releases the clamping force and a mechanical force is exerted on the seat platform carrier or back rest carrier.
