Abstract: A wood-type golf club head comprising toe, heel, top and sole portions, a front face bounded by the toe, heel, top and sole portions, and a rear wall bounded by the toe, heel, top and sole portions, a peripheral wall depending from the periphery of the sole portion to define a sole cavity in the sole portion, and two struts extending from a portion of the peripheral wall adjacent the front face to a portion of the peripheral wall adjacent the rear wall, the struts being in part substantially parallel to each other and in part diverging from each other and defining therebetween and in cooperation with the portion of the peripheral wall adjacent the front face, a central portion of the sole cavity, the peripheral wall being interrupted adjacent the rear wall, such that the central portion of the sole cavity is open to the rear of the club head.      A set of wood-type golf clubs, in which each club in the set has strut members on the bottom of the club defining a sole cavity, and the center of gravity is placed at the optimum location for each club in the set. On the lower lofted clubs the center of gravity is positioned lower in the club, toward the sole. As the loft of the club increases, the center of gravity moves higher, toward the top portion of the club, with the center of gravity highest on the highest lofted club.    As the loft of the club increases, the depth of the sole cavity increases to help to raise the center of gravity. Extra weight may be placed on the top portion of the club, toward the toe portion to further raise the center of gravity. The length of the hosel may also be adjusted to further optimize the location of the center of gravity.

Patent CA-2184285-A1 (CA)
Title: A Method of Draining a Tank and a Plant for Use in Such Draining
Inventor: JONAS J RN M
IPC: F17C9/02
Filed: 1994-12-30
Abstract: A method of draining a tank that has been  containing liquid gas, and a plant for use in such draining.  After draining of the major part of the tank contents, but while residual contents of gas are present in vapourized state in the tank, the residual contents are conveyed for exchanging heat directly or indirectly with cold nitrogen.  Nitrogen is vapourized and heated and conveyed to the tank, while the residual gas is cooled and condensed  and  conveyed  to a collector tank.  The plant comprises a heat exchange system (4, 8; 30, 39) connected to the supply (2) of  nitrogen, and residual gas is forced from the tank to be drained and through the heat exchange system (4, 8) in order to cause vapourization and heating of nitrogen to be conveyed to the tank, in such a manner that the residual gas from the tank condenses,  whereby a collector container (3) is connected for receiving condensed  residual gas.  In order to prevent that the residual gas freezes during  the exchange of  heat a  cooling  agent can be used which causes  vapourization and heating of the nitrogen and which  also  is used for condensing  the residual gas, without cooling the latter to below its freezing point.

Title: Pcs pocket phone/microcell communication over-air protocol
Inventor: ANDERSON GARY B
IPC: H04W56/00
Filed: 1995-03-20
Abstract: A simple and flexible over-air protocol for use with a mobile telephone system, having hand-held telephones    (102) in a microcell or other type of cellular communication system. A method in which user stations (102) communicate with one or more base stations (104) to place and receive telephone calls, in which the user stations (102) are provided a secure voice or data link and have the ability to handoff calls between base stations (104) while such calls are in progress. Each base station (104) has a set of "air channels" to which it transmits in sequence. The air channels supported by each base station (104) are called that base station's polling loop. A user station (102) receives general polling information on an unoccupied air channel, transmists responsive information to the base station, and awaits acknowledgement from the base station. Each base station (104) may therefore simultaneously maintain communication with as many user stations (102) as there are air channels in its polling loop. The ability of a user station (102) to communicate on any unoccupied air channel makes the protocol air-channel agile, while the stability of user station and base station clocks may define air channels, gaps, and minor frames.

Abstract: Apparatus (10) for launching spherical and disc-shaped objects (O) used in the practice or play of a sport. A launcher assembly (12) includes a constantly rotating arm (14) rotatable about a center pivot (P). An object to be launched is loaded into an inlet end (16) of the arm adjacent the pivot for the object to bedrawn outwardly by centrifugal force toward an outer end (18) of the arm from which the object is released. The velocity of the object when it is launched is a function of the length of the arm and the speed at which the arm is rotating. A feed assembly (20) holds a number of homogeneous objects. A feed mechanism (100) of the feed assembly is selectively operable to feed the objects into the inlet end of the arm. A control panel (148) enables a user to remotely control operation of the apparatus, to control individual launches, or to preset an interval at which objects are automatically launched. A drive unit (24) includes a motor (26, 26')for constantly rotating the arm. The motor's speed is controllable to rotate thearm over a range of speeds so to control the velocity of the object when it is launched.
