Title: Bags and method of making bags
Inventor: LERNER BERNARD
IPC: B31B70/74
Filed: 1994-10-06
Granted: 2005-10-04
Abstract: Methods of making a container strip in the form of a chain of interconnected preopened bags with openings preferably having longitudinal dimensions of at least about 1/64 inch is disclosed. The container strip provides greatly enhanced facility for bag registration and opening during packaging operations utilizing the improved container strip. Processes of forming a chain of preopened bags are also disclosed. Face (14) and back (5) plastic webs are fed along individual paths of travel to a common path (28). In one embodiments the webs are differentially tensioned while in their independent paths by stretching the face web, by rollers (18) more than the back web by rollers (20) such that the face web will retract longitudinally more than the back web upon release of the web tension. While so tensioned edge seals are formed between the webs to convert the webs into a tube and longitudinally spaced transverse seals are formed between the webs to delineate bottoms of bags. Transverse lines of weakness are formed in said back web to facilitate separation of bags from the remainder of the web during a subsequent use. Tension in individual bag sections of the face web is released by forming longitudinally spaced transverse separations of the sections and thereby producing a space between each contiguous pair of sections. In other embodiments, pairs of transverse lines of severance are formed in a front section of the webs and parts between the lines of severance are removed to form the novel bags without the need for differential stretching.

Abstract: The rotating printing machine comprises several printing stations in which the form cylinder (16) of each printing station (1,2,3) is driven directly by an asynchronous vectorial electric motor (26/36) controlled by an electronic circuit (101) for monitoring and control of the angular position (a1), at a command value (pLl, 2, 3(t)) that changes over time and is received from a central electronic calculating station (10) for the synchronization of stations with one another. More particularly, the cylinder/axle/rotor assembly (16/65/26) of at least one station can be moved in axial translation for the correction of the lateral registry of the form(s) of the cylinder. In addition, the machine comprises an arrangement (20-23) that reads registry marks (5) printed by each station, and establishes the possible lateral (dl1,2,3) and longitudinal (dL1,2,3) registry error for each station (1,2,3). Each lateral error (dl1,2.3) is then applied to the electronic control circuit (15) of an electric motor (25) of the corresponding station that controls, by means of a mechanism (35), the axial position of the rotor/axle/cylinder assembly (16/65/26). Each longitudinal registry error (dL1,2,3) is added directly to the cylinder position command (pL1,2,3(t)) of the corresponding station.

Abstract: Un appareil de surveillance (1) par radar, à échos d'impulsions non acoustiques, moyenne un grand nombre d'impulsions réfléchies pour produire une tension qui module un oscillateur audio (39) afin de produire un son audible qui correspond aux mouvements d'un coeur ou d'un autre organe corporel. On utilise tant la modulation d'amplitude que l'effet Doppler. Une double constante de temps permet de réduire l'effet des déplacements évidents du capteur sur une surface en cause. L'appareil comporte un générateur d'impulsions (10) qui envoie en entrée une séquence d'impulsions simultanément à un trajet d'émission (12) et à un trajet à porte (14). Lesimpulsions envoyées sur le trajet d'émission commandent un générateur impulsionnel (16) qui crée des impulsions destinées à une antenne d'émission (18). Le trajet à porte comporte un générateur de retard (30) qui produit des impulsions de sélection temporelle conduisant le trajet de réception (15) à n'acheminer que les impulsions renvoyées par les organes corporels (22) et reçues par l'antenne de réception (20). Les deux antennes (18, 20) sont constituées de feuilles de cuivre planes, ce qui permet de les utiliser dans un boîtier pratiquement plat.

Title: Air purifier
Inventor: BRAIS NORMAND
IPC: F24F8/26
Filed: 1997-11-24
Granted: 2004-04-13
Abstract: Disclosed is a chemical and biological air purifier. The air purifier has a housing having an inlet and an outlet both aligned on a longitudinal axis, a turbulence generator, one or more vacuum ultraviolet (UV) sources achieving a chemical purification and one or more germicidal ultraviolet (UV) sources achieving the biological purification.      The turbulence generator is mounted within the housing downstream of the inlet and promotes a dispersion and mixing of air received through the inlet. The vacuum UV source is mounted within the housing downstream of the turbulence generator and breaks oxygen molecules into mono-atomic oxygen which then reacts with chemical contaminants present in the air and degrades them by successive oxidation to odourless and inoffensive byproducts. The turbulence generator reduces the production of ozone by increasing the contact between the mono-atomic oxygen and the chemical contaminants. The germicidal UV-C source is mounted within the housing parallel to the longitudinal axis of the housing downstream of the vacuum UV source. The germicidal UV-C source, in use, kills biological contaminants present in the air by irradiation and degrades residual ozone produced by the vacuum UV sources into molecular oxygen, thereby purifying air from the biological contaminants and residual ozone.

Title: Composite rollers for continuous-belt drilling mud separation unit
Inventor: WILLIAMS J TERRELL
IPC: B07B1/50
Filed: 1998-09-29
Granted: 2006-09-05
Abstract: A pair of cylindrical composite rollers formed of a metallic drum having a thick outer elastomeric layer are mounted transversely in a rectangular frame of a drilling mud separation unit over which a wide endless-loop chain-link belt is driven in a continuous loop moving along the longitudinal axis of the frame. The drive roller has a plurality of axially spaced circumferential rows of radially extending teeth that are machined in the surface of the elastomeric material. The endless belt is formed of a plurality of laterally adjacent jointed links hinged together by transverse rods. As drilling mud or drilling fluids are conducted onto the moving belt, liquids and particles smaller than the openings in the belt pass through the openings and liquids and particles larger than the openings are transported on the moving belt and are discharged off of one end as the belt completes its path. The teeth of the drive roller are sized and spaced to receive and engage the plurality of laterally adjacent jointed links of the wide belt and are of sufficient length to protrude slightly beyond the outer surface of the links as they pass around the front drive roller to dislodge gumbo and other large solids which may otherwise stick in the openings of the links and clog the belt. The elastomeric roller surfaces and teeth reduce wear and prevent metal-to-metal contact and sparking.
