Abstract: A golf putter having a counterbalanced head is provided. The head originates from a section of railway track and comprises a rectangular striking surface. A counterbalancing section is formed at the rear of the putter head and is interconnected to the front of the head by means of a web. An elongate shaft is mounted on said web at substantially the centre of gravity of the putter head.

Abstract: A security lock for a sliding door or window assembly is provided. The lock comprises two pivotally connected overlapping bars having a releasable slider mechanism associated with the pivot point. The lock is adapted to sit in or above the track along which the sliding door or window moves.

Abstract: A synchronous motor/generator is modified by mounting the conventional rotor on a sleeve that rotates freely on the main shaft rather than being fixedly mounted on the shaft. Limits to this rotation are incorporated in the design such that the maximum angular rotation of the rotor on the shaft equals half the stator advance that occurs during a complete full cycle of the AC stator winding voltage. In addition to smoothing transients, this configuration permits the machine to smoothly drop into the correct stator/rotor flux phase when it changes from a motor to a generator, and back into the correct phase for a motor, when the AC power is interrupted, and subsequently resumes, resulting in dropping a single cycle.

Abstract: A sound barrier panel includes an acoustic layer that comprises chipped rubber and cord fiber from tires and a structural concrete layer bonded to the acoustic layer by a combination composite bond that includes both a mechanical portion and a chemical portion. The panel is formed in a special process that can define panels of various sizes, such as twelve feet by twenty-five feet in size. The panel has a high sound absorption capability and a high sound transmission loss, especially at low frequencies, and is extremely weather resistant and durable. The panel is also durable and cost effective and utilizes what otherwise would be potential hazardous waste.

Abstract: A cover unit for an industrial food mixer includes two clamshell-like covers that are hingeably mounted at the proximal ends thereof on the mixer to move in a plane that is parallel to the plane containing the top rim of the bowl in which mixing is being carried out. A splash rib is dependently mounted on each cover as is a splash edge. The splash rib and edge are in the forms of compound curves, and an arcuate cutout on one edge of each cover matches with the cutout on the other cover to define an opening through which beater or agitator elements of the mixer extend into the mixing bowl. The covers move between an open condition uncovering the bowl and a closed condition covering the bowl. A lock mechanism is used to maintain the covers in the locked condition.

Abstract: A stairway connects a stationary member, such as a fixed dock, to a member, such as a floating dock or a floating vessel, which moves vertically with respect to the stationary member. The stairway moves with the moving member and includes stringer members connected to hand rail members by picket members and step supporting pivot arms connected to adjustment arms in a manner which forms a compound parallelogram linkage in which the picket members and the pivot arms remain vertical during movement of the stairway whereby the steps remain horizontal and the hand rails remain parallel to the stringer members during such movement. The stairway includes wheels that rollably engage the moving member and moves between angular orientations as the moving member moves with respect to the stationary member. Steps are mounted on the pivot arms and include walking surfaces which remain horizontally oriented during movement of the stairway.

Abstract: A pitching system, such as a baseball batting practice system, is collapsible whereby it can be stored and transported on a small unit. The unit is releasably attachable to a towing vehicle, such as a pickup truck or the like. The system includes support poles, winding and reeling devices, netting and support wires all of which are stored on the storage unit. In the set up configuration, the system can be modified in three dimensions, including length, width and height, with one section having different dimensions from adjacent sections whereby the particular skill being practiced can be matched by the configuration of the system. The system is also disclosed for use in other sports, such as golf.

Abstract: A face shield is flexible and includes two side wings that are connected to a main body by living hinges and a face-engaging element that spaces the body away from the face of a wearer. A flexible band attaches the shield to the wearer. The face shield body is opaque to the sun and one form of the shield includes cutouts which are covered with sunglasses-type material. The body is preferably cardboard or other such material so the shield can be folded and bent for storage or to customize it for the particular wearer. The shield can be discarded after use if desired.

Abstract: There is provided a device for positioning a golf tee within the ground. The device defines a flat base and at least one tee shaped recess. The recess is adapted to releasably retain in a friction fit engagement a portion of the tee therewithin. Upon withdrawal of the device from the tee, once the tee has been positioned in the ground, the tee remains at a predetermined height in the ground.

Abstract: A lunchbox contains a multiplicity of compartments, some of which can contain items necessary to brush one's teeth. The lunchbox contains a compartment for storing a toothbrush in a closed compartment, a compartment for storing toothpaste and a compartment for storing a cup. The lunchbox also contains pockets for games and drawing equipment which makes the lunchbox attractive to a schoolchild.
