Title: Control for a Door Closer Having a Power-Assist Opening Feature
Inventor: SCHULTZE ECKART F
IPC: E05F15/04
Filed: 1993-06-04
Abstract: A control for a power-assist feature for an hydraulic closer is driven by structure mounted on the pinion shaft of the closer. It includes a pump-activating arm slidably mounted on the shaft, the end of the arm adapted to cover a pump-on sensor when the door is 'bumped'.  It also includes a follower rotatably mounted near the pinion and engageable escapement-fashion by a wheel in friction fit on the pinion shaft, the follower carrying a pump-deactivating arm, the end of the latter arm adapted to move away from a pump-off sensor when the door opens to its pre-set limit.

Title: Method of creating a pillared layered clay (pilc)
Inventor: MCWHINNIE WILLIAM R
IPC: B01J/
Filed: 1992-01-15
Abstract: The method enables the creation of a pillared layered clay (a PILC) by contacting the clay with a pillaring precursor and delivering energy to the reaction mixture to intercalate the precursor into the clay. The pillaring precursor is an electrically neutral organometallic molecule with a carbon-metal bond which is susceptible to proton attack whereby protons donated from sites of Bronsted acidity in the clay cleave the carbon-metal bond to yield an organic fragment of the precursor and a metal-containing pillaring fragment. A preferred precursor is Ph2 SnCl2.

Title: Method and apparatus for cleaning hoses
Inventor: PLUMMER RAYMOND G
IPC: A62C33/02
Filed: 1993-03-08
Abstract: An improved method and apparatus for cleaning liquid-carrying hoses (12), and the like. A suitable cleaning solvent (20 or 22) is passed under pressure through the hose (12). The pressure of the solvent delivered to the hose is measured and used to control the pressure of compressed air (30) mixed with the solvent to maintain a turbulent flow of a predetermined mix ratio for various solvent pressures. The turbulent solvent/compressed air mixture increases scrubbing of the hose to reduce the cleaning time and the quantity of solvent required to clean the hose.

Patent CA-2116842-A1 (CA)
Inventor: SAYAMA TAKASHI
IPC: C05F17/02
Filed: 1994-03-02
Abstract: ABSTRACT OF THE DISCLOSURE         There   is   provided   an   apparatus   for   fast fermentation  treatment  in  which  temperature  of  organic industrial  waste  is  rapidly  increased  to  effect  fast fermentation to allow a low running cost to be achieved.          Hot water is circulated inside a rotary shaft of a main body,  while a  sheath heater is  provided on an exterior surface of the main body.   Organic industrial waste and ferment bacilli are put from an inlet into the main body to increase temperature of the organic industrial waste up to 60°C within one hour by means of the hot water inside the rotary  shaft  and the  sheath heater.    Subsequently,  the sheath heater may be operated intermittently or stopped because natural  fermentation heat  is  generated from the organic industrial waste.

Patent CA-2128252-A1 (CA)
Inventor: LABELLE GILLES
IPC: E21B7/02
Filed: 1994-10-18
Abstract: Cette machine se rapporte à un camion de forage dont la boîte arrière comprend un pivot sur lequel est installé un système hydraulique sur lequel siège un opérateur. L'opérateur peut activer sélectivement les différents contrôles d'un bras hydraulique auquel se rattache une foreuse pneumatique sur rail. Un des principaux avantages de cette machine est que le foreur peut forer sans effort physique et peut faire des trous de 10 pieds de creux sans changer de foret, et; c'est donc beaucoup plus rapide que le forage manuel. Avec une foreuse conventionnelle manuelle, le foreur doit supporter son marteau, qu'il installe sur un foret de 2 pieds et doit appliquer une pression manuelle sur le marteau lors du forage. Quand le trou de 2 pieds de profond est achevé et réinstaller son marteau pneumatique dessus et ainsi de suite, de 2 pieds en 2 pieds, jusqu'à la profondeur désirée, ce qui demande beaucoup de travail musculaire et d'équilibre parce que les trous doivent être forés bien droits.

Patent CA-2134735-A1 (CA)
Inventor: SCHAERF RAYMOND H
IPC: A61M25/00
Filed: 1994-10-31
Abstract: This invention relates to a flexible kink resistant introducer system for introducing an elongated object into the venous system and especially for introducing a cardiac pacemaker lead.   The introducer system features a sheath having a kink resistant section allowing the sheath to be bent in that region and still allow a lead to be introduced therethrough.  The kink resistant section comprises a series of bellows or pleats.  The bellows or pleats may further be arranged to form a screw about a portion of the sheath to thereby permit the sheath to be  screwed into body tissue. The sheath preferably is constructed to readily tear in a longitudinal direction and thus permits the system to be removed from the venous system without having to withdraw the sheath over an end of the pacemaker lead.

Abstract: Disclosed is a diagnostic system for measuring and monitoring  selected operating  parameters  of  a  solenoid operated valve.   The valve assembly, comprised of a valve body, a valve plug attached to a valve stem is actuated or operated by a solenoid.  The valve assembly is provided with one or more sensor means attached to or positioned adjacent to the valve  assembly to measure  and monitor  selected operating parameters of the valve assembly and provide electrical output signals indicative of the measurements to a signal conditioning, processing and data collection means used to receive and record the electrical output signals. The diagnostic system allows the user of the valve to measure and monitor the various electrical and mechanical activities  of  the valve during its  operation while in service and to see if the valve is operating within its design  parameters.    The  valve  diagnostic  system  also provides  the  valve  user with  a  means  to  monitor  the condition of the valve over time in service to detect any degradation or problems in the valve and its components and correct them before a failure of the valve occurs.

Abstract: A latch mechanical (34) for latching a convertible top header (24) to a vehicle windshield header (18) comprises a latch hook receiver (124) mounted adjacent to each end of the windshield header (18) and a pair of movable latch members (104) each having a free end mounting a hook (108). A mounting bracket (76) located adjacent to each end of the top header (24) has an elongated base slot (96, 98) and an intersecting curvilinear branch slot (100, 102) adjacent to its outer end. A guide pin (120) and a spaced drive pin (114), carried by each latch member (104), are received within the respective slots (96, 98) and (100, 102) in the unlatched position. A drive link (66), electrically driven or hand-operated, is connected to each latch member drive pin (114). Operation of the drive link (66) pivots the latch members (104) about the guide pins (120) until the drive pins (114) enter the base slots (96, 98) and terminally slide both pins (114, 120) toward the inner ends of the base slots (96, 98) to move the latch members (104) from unlatched to latched positions. This moves each hook through a compound curvilinear path (X, Y) between an unlatched position stored within the top header (24), and a latched position, extending from the top header (24).
