Title: Poultry processing apparatus and method
Inventor: TIELEMAN RUDOLF J
IPC: B65G47/53
Filed: 1990-04-06
Abstract: ABSTRACT OF THE DISCLOSURE           A poultry processing machine supports birds on mandrels mounted on carriers which move in a rectangular path.  The birds move continuously in opposite directions along two opposite sides of the rectangular path; and, they move intermittently in opposite directions along the other two sides of the path.          Continuous movement is provided by chains with lugs which enter recesses formed in the carriers.          Intermittent movement is provided by cylindrical cams which engage cam followers on the carriers and also force adjacent carriers together to couple them.  The mandrel has a groove for receiving the backbone, projections for engaging the kidney spaces inside the body, and a shoulder for engaging the anterior end of the breastbone.  It is pivoted to an upright position, a back-up position and a breast-up position as it travels around the apparatus.  At the corners of the path, the carriers change their direction of movement without turning bodily.  The bird's skin is cut around the perimeter of the thigh, the thigh joint is disjointed, the ligaments and/or tendons in the thigh joint are severed, and the leg is pulled from the body while the body is moving in an anterior back-up position.  The wing/breast parts are pulled from the body when the body is moving in an anterior breast-up position.

Title: Golf club head cleaner and divot repair tool
Inventor: HAUGOM HOWARD
IPC: A63B57/60
Filed: 1990-05-17
Abstract: ABSTRACT          The invention provides a small, inexpensive cleaning device that is particularly made to clean the grooves in the face of most golf clubs, both irons and drivers. The object of grooves on a golf club is to give the ball direction and backspin. If these grooves become clogged the player no longer gets the proper backspin on the golf ball and loses directional accuracy. The device has at one end a series of small evenly spaced fixed prongs. The device is twisted to enable cleaning of a variety of evenly spaced parallel grooves. Additionally, the device has a pair of large sharpened prongs on its opposite end, which can be used to clean golf shoes and to to repair divots on golf course greens.

Title: Apparatus for measuring weight, torque and side force on a drill bit
Inventor: MARON ROBERT
IPC: E21B47/00
Filed: 1990-05-28
Abstract: APPARATUS FOR MEASURING WEIGHT TORQUE AND          SIDE FORCE ON A DRILL BIT     Abstract of the Invention:     Apparatus is presented for measuring weight, torque and side force (bending) on a drill bit for oil and gas well drilling.  This apparatus includes radial holes which do not pass completely through the wall of the drill collar sub, but instead, pass only partially through the wall of the drill collar sub.  Strain gages are located in the partial radial openings.  These strain gages measure each of the three parameters of weight, torque and bending.  Each partially formed hole is sealed by a plug and retained in place by a retaining ring.  For torque and bending measurements, the strain gages are arranged with symmetry of position between diametrically opposed holes. The strain gages are positioned in an array which departs from symmetry of position to minimize errors in the weight measurement caused by pressure changes in the drilling fluid.

Title: Pharmaceutical preparations for oral administration that are adapted to release the drug at appropriate sites in the intestines
Inventor: IKUSHIMA HEIJI
IPC: A61K9/58
Filed: 1990-05-10
Abstract: An oral preparation composed of a core comprising a principal agen and a pharmaceutically acceptable filler; the first layer covering the core, which comprises an enteric or water-soluble component and may optionally contain an insoluble component; the second layer covering the first layer, which comprises a nonenteric component which dissolves by reacting with at least one component of the core; and the third layer covering the second layer, which comprises an enteric component. This preparation will not release the principal agent until it reaches a desired region in an intestine and it can release the agent at a controllable rate once it reaches that region. Thus it can be effectively used in administering a principal agent having an absorption specificity at a particular region in the intestine or treating a disease at a particular region in the intestine.

Abstract: The present invention is directed to an improved process for the production of a water-absorbent resin by reversed phase suspension polymerization of a water-soluble ethylenic unsaturated monomer.  The process is conducted by subjecting an aqueous solution of a water-soluble ethylenic unsaturated monomer to a reversed phase suspension polymerization reaction in a first stage.  The polymerization is conducted in a petroleum hydrocarbon solvent in the presence of a surfactant and/or polymeric protective colloid using a radical polymerization initiator optionally in the presence of a crosslinking agent, cooling the resulting slurry to precipitate the surfactant and/or polymeric protective colloid, and then repeating the polymerization by adding an aqueous solution of a water-soluble ethylenic unsaturated monomer containing a radical polymerization initiator and optionally a crosslinking agent to the first polymerization reaction system to further carry out the reversed phase suspension polymerization reaction, at least, once.

IPC: C04B35/80
Filed: 1991-03-12
Abstract: A masking is provided along the position of one each folding or separation line (45 1 to 45 6), in order to prevent the infiltration of the matrix material into the  or  each  masked  zone  of  the  preform.    After densification  of   the  preform  by  chemical   vapor deposition  and  removal  of the  masking,  the  or  each masked zone of the preform constitutes a flexible bond integrated to the densified preform.   Advantageously, the masking of the preform is maintained during a first densification phase until the unmasked parts  (40 1 to 40 7) are consolidated.   The masking is then removed to obtain  flexible bonds  integrated to  the consolidated preform, allowing the latter to be brought to a shape corresponding  to  the  component  by  folding  along  the lines corresponding to the flexible bonds, after which the  densification  is  continued.    Alternatively,  the masking   can   be   removed   only   after   the  final densification to obtain a composite  component  having one, or a number, of articulations.
