IPC: F16B13/12
Filed: 1995-10-04
Abstract: An all-metal expansible hollow anchor and nail assembly adapted to fasten to masonry a fixture or other object having a mounting hole.  The anchor which goes through the fixture mounting hole into a hole drilled in the masonry, is provided with a head that then engages the fixture and an expansible body projecting from the head into the drilled hole whereby when the nail is driven into the hollow anchor, the anchor body then expands against the wall of the hole to lock the anchor therein.  The expander nail has a head whose diameter is greater than that of the drilled hole and a shank of smaller diameter joined to the underside of the nail head by a junction section of progressively increasing diameter whereby  the  shank  gradually  merges  with  the  head. Countersunk in the head of the anchor is a well that conforms to the shape of the nail head and the junction section, the well receiving and nesting the nail head and junction section when hammer blows are applied to the nail head.  The force of these blows is transferred by the nail head and the junction section to the surrounding region in the anchor head to develop compressive stresses therein that act to retard further advance of the nail and to prevent the production of shear stresses that may cause the anchor head to separate from the body of the anchor.

Title: A device for processing flat fish
Inventor: HJORTH JENS
IPC: A22C25/14
Filed: 1994-05-05
Abstract: An apparatus and method for processing fish (24), especially sole, is disclosed. The apparatus includes a frame having a longitudinal axis along the direction of movement of the fish as they are processed. The fish are placed onto a conveyor (200) that includes blocks (204) for centering the fish and advancing them parallel to the longitudinal axis of the frame and into jaws (202). The jaws open as the fish passes through and measure each fish as well as help center the fish. The length measurement taken by the jaws is sent to a logic controller that determines the approximate dimensions of the fish. The controller uses this information to activate cutters at the proper times. The cutters include dorsal and anal fin cutters (212, 210), a tail cutter (214), and a head and organ cutter (216). The fish is carried into the cutters by spiked belts (222, 224, 230, 232, 234). The belts also transport the fish through an exit chute (362) into more processing equipment or simply into an exit bin. Circular blades (312, 314) are used for the dorsal and anal fin cutters. The blades are moved transverse to the longitudinal axis of the frame as they cut the fins. The tail cutter and head and organ cutter are cutter are constructed of flat steel bars with serrated edges. These cutters are activated at the proper time by the logic controller to swing around and cut off the tail, head, and organs.
Patent CA-2169279-A1 (CA)
Title: Improved electrostatic filter
Inventor: THOMPSON DONALD E
IPC: B01D35/06
Filed: 1994-08-11
Abstract: An electrostatic filter (10) utilizes two separate filter cartridges (42, 44) in a parallel flow configuration with respect to incoming dielectric fluid containing particulates. Each cartridge is connected to opposite sides of a high voltage power supply (100), resulting in the electrodes (50) contained in one of the cartridges having an opposite polarity than the electrodes (60) contained in the other cartridge. This, in turn, results in having the fluid born particulates exiting one cartridge being charged, oppositely to those exiting the other. The fluid streams exiting the two cartridges are joined together, allowing the particulates to flocculate. These larger groupings of particulates may then be mechanically filtered in a third cartridge (46). The parallel flow configuration results in an electrostatic filter that is relatively insensitive to water contained in the dielectric fluid.

Title: Height-adjustable table
Inventor: ALEXANDER BRIAN D T
IPC: A47B9/14
Filed: 1996-05-27
Abstract: A table provided with an enlarged sheetlike top supported in upwardly spaced relation from a floor by a leg structure which is fixed to and projects downwardly from the underside of the top.  The leg structure includes substantially identical right and left leg arrangements secured under the table adjacent opposite ends thereof, each leg arrangement including a bottom leg part which includes generally parallel and upright front and rear leg members rigidly joined together by a plurality of vertically spaced and horizontally extending cross rods.  The front and rear leg members have the upper portions slidably and telescopically received within individual front and rear upper leg parts, which upper leg parts and the lower leg members have a series of cooperating holes which accommodate a removable locking element to permit telescopic height adjustment.  The upper leg parts have transversely extending upper tubular portions which project longitudinally of the table and are positioned directly under the undersurface of the top.  These upper tubular portions, disposed in the vicinity of the corners of the table, are oriented so that the front upper leg parts have the upper tubular portions aligned and rigidly joined to an elongate support shaft or tube extending therebetween directly adjacent the undersurface of the table top adjacent the front edge, and the rear upper leg parts have the tubular portions similarly joined to a further support shaft or tube which is disposed adjacent the undersurface in the vicinity of the rear edge of the top.  These support tubes in turn are rotatably positioned within hangers or brackets which are fixed to the underside of the top.  This allows the support shafts to undergo a limited angular rotation relative to the table top which, in conjunction with the configuration of the telescopic leg arrangement, enables the adjusted height of the front and rear leg arrangements to be slightly different so as to permit the top to assume at least a small incline from front to rear.
