Title: Hollow hockey shaft to blade locking device
Inventor: BOGDANOVICH ZORAN
IPC: A63B53/02
Filed: 1993-04-16
Abstract: ABSTRACT OF THE DISCLOSURE    A Hollow Hockey Shaft to Blade Locking Device is made in several basic shapes. Common for all of them is that they have a head that goes into the hockey shaft, and body that locks on the replaceable hockey blade. The head is a square plate attached to the hockey shaft inner surface by any available method of joining the two parts. Another design for the head comprises a tongue in the centre oriented toward the body.  This design requires a suitably shaped groove on the inner surface of the hockey shaft so that the tongue can lock in this groove. The body is T-shaped plate connected to the head with its neck. Another design for the body is square plate with rectangular opening in the centre. Both designs require suitably shaped groove in the neck of the hockey blade so that the end portion of this part can lock in it. This locking device is to be made of resiliently flexible material. A broken hockey blade can be removed by simply lifting the end portion of the locking device from the groove in the neck of the hockey blade so that the hockey blade is unlocked. New hockey blade can be fixed to the hockey shaft simply by snapping them together.

Abstract: ABSTRACT OF THE DISCLOSURE     A pair of elongated cylindrical members are constructed with first and second collars extending axially beyond their adjoining ends.  The first and second collars have adjoining indentations and projections at their end edges which are adapted to interlock with one another so as to prevent rotation of the two elongated members with respect to one another.  A coupler is removably fitted over the exterior of the first and second collars and holds them together against axial movement with respect to one another.  The collars are each welded to the axial ends of the first and second cylindrical members.  A sampling tube section is provided having slots to allow the fluid to be sampled to enter the internal bore of the tube.   The slots are axial, and are spaced apart both angularly and axially.   The slots are tapered so as to have a narrower width at the outer surface of the tube than at the inner surface of the bore.

Title: Method for Stabilizing an Agent for Contact Lenses
Inventor: NAKAYAMA HISAYUKI
IPC: C11D3/386
Filed: 1994-02-02
Abstract: A method for stabilizing an agent for contact lenses containing a proteolytic enzyme by adding a surfactant to a solution containing an effective amount of a proteolytic enzyme, the production of a lyophilized agent for contact lenses containing a proteolytic enzyme, which comprises subjecting an aqueous composition containing a proteolytic enzyme to a lyophilizing treatment in the presence of a surfactant, and a lyophilized agent for contact lenses which contains a proteolytic enzyme and a surfactant.  The method of the present invention enables stable preservation of a proteolytic enzyme in a liquid form.  In addition, cleaning, sterilization and preservation can be simultaneously performed with a single solution, wherein an efficient removal of soil is achieved by only immersing contact lenses in the agent in a solution state.          Accordingly, the agent of the present invention is advantageously used with ease by simple handling.  The method for producing the lyophilized agent of the present invention enables stabilization of a proteolytic enzyme during preparation into a lyophilized formulation.  Furthermore, the lyophilized agent of the present invention permits the proteolytic enzyme to remain stable and is extremely superior in solubility.  When preserved as an aqueous solution, the stability of the enzyme can be maintained over a long period of time due to the action of a surfactant contained therein.

IPC: A63B53/04
Filed: 1994-03-03
Abstract: A golf club head of an improved aerodynamic design, which includes deep cavities for airflow stabilization. Adjacent rims of these cavities meet to form a central rib. Cavities can be joined at both ends of the rib to form a continuous cavity or can be separated along their entire length to create two different cavities and in either case run parallel to the edges of the rear face. The cavities accommodate air turbulence and swirl, and the centrifugal force produced by the swirl in those cavities in the head imparts a thrust upon it which thus minimizes drag and maximizes the force with which it strikes and drives the ball. The cavities also minimize undesired aerodynamic vibration in the golf club so as to enhance the player s accuracy.
