Patent CA-2108783-A1 (CA)
Title: Pulsator for irrigation systems and the like
Inventor: KRAUTH RICHARD G
IPC: B05B1/08
Filed: 1992-04-28
Abstract: A pulsator, adapted for use in irrigation and other systems requiring the uniform discharge of water or other liquids in intermittent pulses and at regular frequencies, comprises a casing (11) having an expansible elastomeric tube (18) disposed therein. The tube is adapted to be exposed to pressurized liquid for movement between contracted and expanded conditions of operation for controlling the intermittent opening of a valve (20), formed in part by the tube. A flow control (21), located at the inlet to the pulsator, functions to modulate the pressure of the incoming liquid to control the flow rate of the liquid communicated to an expansible chamber (19) defined in part by the tube. When the pressure in the chamber exceeds a predetermined level, the valve (20) will open to intermittently discharge pulses of liquid to a distributor, such as an irrigation sprayer.

Title: Photoconductive impedance-matched infrared detector with heterojunction blocking contacts
Inventor: SCHIMERT THOMAS R
IPC: H01L31/0216
Filed: 1994-07-29
Abstract: A photoconductive isotype heterojunction impedance-matched infrared detector has blocking contacts (66 and 68) which are positioned on the bottom side of the detector. Blocking contacts (66 and 68) prevent transfer of minority carriers from active region (42a) of the detector, thereby extending the lifetime of these carriers. The detector is formed by first fabricating active layer (42) followed by isotype blocking layer (44) on growth substrate (40). These layers are etched and appropriate passivation layers (93) and contacts (98 and 100) are applied. Mechanical supporting substrate (90) is applied to the detector and growth substrate (40) is removed. Etch stop holes (48 and 50) are formed which extend into active layer (42) of the detector. A precision thickness of active layer (42), required in an impedance-matched detector design, is produced by thinning active layer (42) in an etching process until the surface of active layer (42) reaches etch stop hole (48 and 50).
Patent CA-2143164-A1 (CA)
Title: Loop buffer for strip conveyor
Inventor: KELLER GUIDO
IPC: B65H20/34
Filed: 1995-02-22
Abstract: A loop buffer having an input and an output deflector roll and a loop roll flexibly mounted between them in a basically vertical position, with its height relative to the deflector rolls determining the loop length of the strip material to be transported. The loop roll is gravity tensioned via a relatively weak spring by a ballast body guided with free movement in a basically vertically direction. In particular the loop roll and its bearing elements moving together with it have an extremely small inert mass of preferably only a few grams. The loop roll also includes two or three parallel coaxial loop wheels of slightly different diameter, adapted to the thickness profile of the strip material, transverse to the longitudinal direction.  By selecting a relatively weak spring, the loop roll can follow small but quick changes in the transport speed very easily and quickly, with the acceleration forces caused by the low inert mass of the moving parts remaining very low. Larger drift movements of the loop roll because of speed differences of greater duration between the feeding and removal of the strip material have the effect of displacing the ballast body, the gravity tensioning of the loop roll and thus the tension exerted on the strip material always remaining constant. The loop roll always remains in good contact with the strip material and guides it correctly. The notorious jumping of the loop roll in the strip material loop which occurs in traditional loop buffers, and the consequent impacts on the strip material, are practically eliminated even under extreme conditions. By dividing the loop roll up into several loop wheels, the loop buffer is particularly suitable for photographic film material made up of individual shorter strips, and also with paper strips along the edge.
