Title: Coupling and transmission mechanism for drape or blind assembly
Inventor: MAROCCO NORBERT
IPC: E06B9/262
Filed: 1991-02-07
Granted: 1999-08-24
Abstract: A drape or blind assembly having a headrail in which there is disposed a shaft, on rotation of which the position of the drapes or blind slats is adjusted, and a transmission mechanism which comprises a drive gear and a coupling adapted to be coupled to such a shaft so that rotation of the drive gear normally causes rotation of the shaft. If, however, the drive gear is rotated past a predetermined rotational position, a stop member generally provided on the coupling engages an abutment member to prevent further rotation of the shaft. To prevent damage to the mechanism in such a situation, the mechanism includes a recess defined by first drive surfaces and a resilient arm means having Complementary second drive surfaces. On continued rotation of the drive gear after the stop member has engaged the abutment member, the resilient arm means flexes to permit relative rotation of the first and second drive surfaces. Bearings are provided in the headrail far rotatably supporting the shaft, and retaining it in position.

Granted: 1994-05-03
Abstract: ABSTRACT           A toilet roll cover suitable for covering both wall mounted and free standing toilet rolls is disclosed.  The invention provides embellishment of the interior design of a bathroom and may enhance hygiene and air quality.  The invention comprises a piece of material, preferably lined with stiff interfacing, formed into a generally cylindrical shape with a longitudinal opening running substantially from end to end.  The generally cylindrically shaped piece is formed by placing the piece around a new roll of toilet paper and pulling radially inwardly the piece's lateral ends across most of the area of the ends and securing the ends by fastening means such as a ribbon threaded through a sewn channel.  The preferred embodiment is further characterized by a band of lace or the like running longitudinally adjacent one side of the longitudinal opening, forming a pouch which can accommodate fragrance exuding means such as pot pourri.

Title: Valve assembly for fluid pressure regulation
Inventor: WHITE LAWRENCE W
IPC: G05D16/06
Filed: 1991-06-03
Granted: 1994-10-04
Abstract: ABSTRACT OF THE DISCLOSURE     A valve assembly for fluid pressure regulation provides freedom from static pressure creep by eliminating distortions and stresses normally introduced to valve parts during assembly of the regulator.  A floating valve seat permits normal installation of a valve housing in the regulator body with no transfer of stress or distortion to the valve seat. Thus static pressure creep, normally attributable to micro distortions of the valve seat, is avoided.  Options are also provided to install the floating valve seat directly in a regulator body without the valve housing.
Patent CA-2046269-C (CA)
Inventor: SCHNEIDER GEORG
IPC: G01L1/22
Filed: 1990-11-30
Granted: 1999-12-21
Abstract: The arrangement serves to process sensor signals furnished by a sensor which when fed with a supply signal in response to the action of a physical measured quantity generates a measuring effect representing the dependence of an electrical characteristic quantity on the physical measured quantity. It includes a signal processing circuit which operates by the principle of quantized charge transport by means of switch-capacitor structures, The signal processing circuit establishes a charge balance by opposite integration of measuring charge packets dependent on the measuring effect and compensation charge packets independent of the measuring effect and furnishes an analog output signal corresponding to the integration result. The supply of the sensor is influenced by feedback of the analog output signal or of a feedback signal in fixed relationship thereto for obtaining the charge balance. By this feedback the analog output signal is regulated so that it is proportional to the measurement result.

Title: Portable underwater swimming pool light
Inventor: KIELLAND PETER J
IPC: F21S8/00
Filed: 1991-07-29
Granted: 1993-06-22
Abstract: ABSTRACT PORTABLE UNDERWATER SWIMMING POOL LIGHT A portable light fixture which illuminates the volume of water in a swimming pool to create a pleasing night-time appearance. The light source and all attendant electrical hardware are mounted above the water's surface to avoid the normal measures required to waterproof the light. Light from this element is projected downward into the water through a light shaft which which hangs over the edge of the pool and extends down below the water line. This combined light transmission shaft and light element enclosure is opaque to prevent any light escaping above the water line and detracting from the pool illumination effect. It also acts as a stilling well to calm the air/water boundary where the light rays enter the pool. The light shaft is vented to allow water to rise within itself to the same level as in the swimming pool. Light travels down the light shaft, traverses the air/water boundary and then exits the light shaft below the water line, These light rays then strike a reflective light diffuser suspended directly below the shaft exit. The light diffuser is conical in shape and vertically bisected. It spreads the beam away from the pool wall by reflecting the vertical rays exiting the light shaft into a horizontal fan pattern. Safe power to the lighting element is supplied via a standard commercially available ground fault protector or low voltage transformer located at a distance from the pool area. A non-standard connector on the line from the remote power supply insures that only safe power can be connected to the light apparatus.

Title: Process for coiler drum alternation in incessant hot rolling and apparatus therefor
Inventor: KOMAMI YUJI
IPC: B21B39/00
Filed: 1991-07-30
Granted: 1997-01-21
Abstract: Disclosed herein is a process for coiler drum alternation in incessant hot rolling in which continual finish hot rolling of rough-rolled sheet bars united on the entry side of a finishing hot rolling mill is carried out by tilting upper and lower tillable pinch rolls disposed on the exit side of a shear on the downstream of the finishing mill, thereby changing the traveling direction of the steel strip so that a leading end formed upon cutting the strip will be directed toward the next coiler drum to be used, and thereafter cutting the strip. This process enables an easy and assured alternation of coiler drums, thereby contributing to increases in the speed and efficiency of incessant hot rolling.

Title: Conveyor system having non-singulating accumulation conveyor
Inventor: WOLTJER BERNARD H
IPC: B65G47/26
Filed: 1991-10-29
Granted: 2004-06-22
Abstract: A conveyor system includes an accumulation conveyor that is particularly useful in a location outbound of a sortation spur in combination with a receiving conveyor which receives products from the accumulation conveyor at a generally constant rate. The accumulation conveyor includes a plurality of powered rollers that are selectively actuatable in groups of tandemly arranged zones in order to convey product to the receiving conveyor. A product sensor associated with each zone senses the presence of product in that zone, and a control that is responsive to the product sensor actuates all of the rollers associated with zones upstream of any sensor that is not sensing product in order to transport product to the receiving conveyor without singulation, yet provide an accumulation capability. The control is pneumatic and uses pilot-actuated valves configured in a manner that connects the associated roller drive actuator directly with a source of pneumatic fluid in order to provide an exceptionally responsive control.
