Patent CA-2001145-A1 (CA)
IPC: A22C25/12
Filed: 1989-10-20
Abstract: The present invention relates to an apparatus for the orientation of fish with respect to the position of abdomen and dorsum. The fishes (6, 7) are thrown head first against an oblique, preferably curved guide element ( 5 ) in such a way that the centre of gravity of the head (8) of the fish lies sidewards from the perpendicular to the guide element (5) through the contact point of the fish, due to which the fish turns into contact with the guide element ( 5 ) and into the same orientation with respect to the direction of abdomen and dorsum, irrespective of, whether the fish hits the guide element with dorsum or with abdomen.

Title: Removal of dissolved gas from ink in an ink jet system
Inventor: HINE NATHAN P
IPC: G01D15/16
Filed: 1989-10-25
Abstract: In the particular embodiment of a device for removing dissolved gas from ink described in the specification, an elongated ink path (27) leading to an ink jet head (11) is formed between two permeable fluorine-containing membranes (30,31). The membranes are backed by air plenums (32,33) which contain sup port members (34) to hold the membranes in position.      Reduced pressure is applied to the plenums to extract dissolved gas from the ink in the ink path without accumulating scum on the membrane surfaces. Increased pressure can also be applied to the plenums to eject ink from the ink jet head for purging. Within the ink jet head, ink is circulated convectively from the orifice (35) to the deaerating path (27) even when the jet is not jetting ink.

Abstract: DRAWER INTERLOCK A drawer interlock for a drawer-and-cabinet assembly wherein a cabinet mounts one or more drawers for sliding movement between a retracted position in the cabinet housing and an extended position at least partially out of the front of the housing. The interlock comprises a latch pivotably mounted to the cabinet back wall proximate to a back wall of the drawer or drawers with the latch having an upstanding catch and a depending catch extending from a central portion in vertical relationship. The latch interfaces with a hook on the drawer or drawers in the cabinet to prevent more than one drawer from opening at one time. The latch is pivotably mounted and biased against the hook in such a way that the latch does not interfere with the movement of any one drawer but will engage a hook when more than one drawer is opened at a time. In a preferred embodiment, each cabinet has one drawer and the latch interfaces with the drawer in the cabinet and with a drawer in an adjacent cabinet, preferably mounted on a wall. Each drawer has two hooks for interfacing with the latch in the cabinet and with a latch in an adjacent cabinet.

Title: Manufacture of peroxides
Inventor: NUGENT ANTHONY J
IPC: C22B3/44
Filed: 1990-04-04
Abstract: ABSTRACT                 Manufacture of Peroxides Conventionally, gold and silver are obtained from their ores by agitation leaching the ore, after grinding, with an oxygen-containing aqueous alkaline cyanide solution. Problems that can be encountered in the leaching include long leaching times, maintenance of sufficient dissolved oxygen and high consumption of cyanide, which can result in slow or impaired extraction of precious metal.            The addition of small amounts of poorly soluble inorganic peroxides and particularly calcium peroxide, such as from 0.1 to 20 parts w/w per 1000 parts of ore provides a convenient way to control and maintain suitable levels of dissolved oxygen and can result in one or more benefits of increased or more rapid extraction of the precious metal and reduction in cyanide consumption.   The insoluble divalent metal peroxides can be produced at a controlled rate demanded by the leaching process by monitoring the dissolved oxygen level in and the pH of the leaching process, and using the monitored levels to control the rate of addition of hydrogen peroxide to divalent metal compound and the mole ratio of the two reagents.

Abstract: ABSTRACT OF THE DISCLOSURE   A three cone earth boring bit having circumferential rows of earth disintegrating teeth of wear resistant inserts of selected projection from the cone surfaces, one cone having an inner row separated from a heel row by a narrow circumferential groove and a second cone having a hell-catching row that intermeshes with the narrow groove by an amount to minimize balling. A nozzle directs a jet stream with a high velocity core past the cone and inserts of adjacent cutters to the bore hole bottom to break up the filter cake while the lower velocity skirt strikes the material packed between the inserts of adjacent cones. A row of small diameter, recessed reaming inserts replaces the conventional heel row on the cone having a hell-catching row, thus providing space for the lateral displacement of the material generated between adjacent inserts in the critical hell-catching row.
