IPC: A61F2/38
Filed: 1993-02-18
Abstract: MODULAR SHAPING AND TRIAL REDUCTION GUIDE FOR IMPLANTATION OF POSTERIOR-STABILIZED FEMORAL PROSTHESIS AND METHOD OF USING SAME        ABSTRACT           According to the invention, there is provided a trial  implant  (10)  comprising a modular bracket  (12) defining a structure having an internal surface adapted to be seated on the distal aspect (14) of a resected femur bone (16) and an external surface with a shape resembling the normal distal condyle of the femur.  The bracket has an elongated central opening (18)  appointed to expose the resected bone of the femur, including a pair of tracks (20) for guiding a first shaping tool (22) along a predetermined path for controlled shaping of a patellar groove in the bone exposed through the opening.  An end mill guide (300) cooperates with the bracket  (12)  to receive a second shaping tool (304) to form a deep rececs for accommodating a posterior-stabilizing housing.  After the recess is formed, the guide (300) is replaced with an insert (322) having a posterior-stabilizing housing which covers the opening of the bracket and articulates with a proximal aspect of the tibia during interoperative trial reduction of the knee joint.   Removal of the bracket from the resected bone is unnecessary following the shaping steps prior to performing the trial reduction.

Title: Mechanical energy storage for vehicle parking brakes
Inventor: TAIG ALISTAIR G
IPC: F16D65/28
Filed: 1991-10-30
Abstract: The parking brake system (10) includes a spring operated actuator (30) which includes a screw (37) having thereabout a nut (38) affixed to a laterally movable cap (32) biased by springs (34, 35) within the actuator (30). The screw (37) is connected with a gear mechanism (40) that can rotate a flywheel (60) connected selectively with an electric motor (20). The screw (37) of the spring operated actuator (30) is connected with flexible drive mechanisms (50) that are connected with brakes (18, 19) of the vehicle. The spring operated actuator (30) is in a compressed mode when the brakes (18, 19) have not been applied for parking. When the vehicle operator activates the parking brake system (10), spring expansion causes the movable cap (32) and nut (38) to move laterally which causes the screw (37) and gear mechanism (40) to rotate so that the flywheel (60) is also rotated. As the springs (34, 35) expand, the kinetic energy stored within the flywheel (60) is fed back into the parking brake system (10) to effect full application of the brakes (18, 19).

Title: Winterizing device for inground swimming pools
Inventor: VOIGHT TERRANCE R
IPC: E04H4/06
Filed: 1993-05-26
Abstract: ABSTRACT   A device for use in winterizing inground swimming pools avoids the necessity of draining the pool in order to drain underground water-filled conduits before freeze-up. The device is an elongated cofferdam open at top and rear with a groove for receiving a sealant extending along the rear edge of side and bottom walls. The sealant, such as a denture adhesive, will hold the device against the pool side wall surrounding a water inlet, and so that the device opens above the water surface. Water within the device and the conduit leading to the inlet is pumped therefrom and then a plug is inserted in the inlet to prevent pool water from entering the inlet after the device is removed from the pool side wall.

Title: Device to absorb energy transmitted through steering column for a vehicle
Inventor: SPEICH GERALD ANTHONY
IPC: B62D1/19
Filed: 1993-02-26
Abstract: A device to absorb energy transmitted through a steering column for a vehicle in the event of a vehicle crash and/or driver impact on the steering wheel includes a slotted member (7) in the form of a saddle bracket for connection to a steering column, a second member in the form of a bolt (5) or the like extending through the slot (II) of the first member and a third member in the form of a strap (12) which is arranged to restrict relative movement between the first and second members upon vehicle crash etc. The strap (12) is stiff but ductile and is wrapped over the bolt (5) so that, if the steering column (I) collapses, the bolt will move in a direction out of the slot (II) of the first member and run into the strap (12) which is then unwrapped, thereby absorbing energy transmitted through the steering column. The strap (12) can also itself be slotted.

Title: Process and device for the continuous moistening of grain and use of themoistening device
Inventor: MULLER ROMAN
IPC: B02B1/06
Filed: 1993-07-27
Abstract: Abstract The new invention proposes the damping of grain, for example, by creating a rotating layer (20) in a damping chamber (2) with the help of acceleration rotors (3).  For this, the cross-section of the rotation chamber is designed to form an outer boundary around two or, preferably, three acceleration rotors (3, 3', 3").  In this way, the rotating layer is forced into an eccentric and spi-ralling motion within the damping chamber (2).  Damping is car-ried out in a very gentle manner, so that there occurs hardly any abrasion and no grain damage.  Additional advantages include a longer and controllable reaction period during damping, optimized preparation for milling and a shorter, controllable tempering period.
