Title: Audible golf gloves
Inventor: SUTTLE KEITH H
IPC: A63B69/36
Filed: 1993-01-21
Abstract: AUDIBLE GOLF GLOVES   ABSTRACT OF DISCLOSURE A pair of golf gloves for teaching a golfer to maintain his grip about a golf club during a golf swing. The pair of golf gloves comprises of a control-hand glove which fits about a golfer's control hand and a power-hand glove which fits about a golfer's power hand. The control-hand and power-hand gloves are designed with an audible emitter which audibly signals to the golfer when the golfer's hands initially begin to break or separate during the golf swing. The audible emitter includes a first cooperating VELCRO? section strategically attached to the control-hand glove and a second VELCRO? section strategically attached to the power-hand glove. The first VELCRO? section located about the palm side in the base area of the thumb of the control-hand glove, and the second VELCRO? section located about the palm side along the lower base area of the power-hand glove. The cooperating first and second VELCRO? sections mate when the golfer assumes a golf grip about a club handle, and are strategically positioned on the gloves to mate together at the location where the golfer's hands have a tendency to initially begin to separate during a golf swing. The mated first and second VELCRO? sections separate as the golfer's hands come apart during a golf swing, and cause an audible sound to be produced. The audible sound signals to the golfer the point in the golf swing where the grip about the golf-club handle was initially released.

Title: Adjustable height chair arm
Inventor: SCHULTZ CRAIG H
IPC: A47C1/03
Filed: 1993-02-26
Abstract: ABSTRACT OF THE DISCLOSURE An adjustable chair arm assembly is provided which can be vertically adjusted in order to readily accommodate users of different sizes.  The chair arm assembly provides support members having overlapping portions which cooperate to slide vertically with respect to each other.  One of the support members maintains a relatively fixed position with the chair and the other support member, having an arm rest, slides vertically with respect to the first support member to adjust the height of the arm rest. A series of support projections are vertically disposed along the overlapping portion of one of the support members.  A latch member, mounted for sliding movement along the support projections, has at least one latch projection for selectively engaging the support projections at any position therealong.  Resilient means is coupled to the latch projection for urging the latch projection into engagement with the support projections thereby preventing the support members from sliding with respect to each other for supporting the arm rest in any selected height position.      Manipulatable handle means is coupled to the second support member and attached to the latch projection for supporting the load created when the user leans on the arm rest, and for selectively retracting the latch projection from the support projections, thereby permitting sliding movement between the support members in order to adjust the height of the arm rest.  When the handle means is released, the resilient means urges the latch projection to reengage the support projections in the selected position.

Title: Process and mechanism for the automatic manufacturing of articles made from plastic, particularly from recyclable plastic
Inventor: ATILLO GUISEPPE
IPC: B29C45/66
Filed: 1993-04-07
Abstract: ABSTRACT:      This  invention  relates  to  automating  a  process  for manufacturing articles from plastic,  particularly recyclable plastic waste.   A lengthened separator head is flanged to a plasticizer to supply melting serially to several molds, by way of mold inlet shut-off mechanism. A preprogrammed control device monitors the filling of a respective mold by way of a pressure sensor in the mold.  When the desired filling of the mold has occurred, the inlet shut off mechanism is closed by the control device and another mold that is ready to be filled is filled with melting by the opening of the corresponding inlet shut-off mechanism at the another mold.  In addition, the control device controls the locking and tightening of the mold as well as its opening and emptying.

Abstract: An assembly for restraining oil leakage in a rotary oil well pump includes a stationary member and a rotary member. The rotary member is secured to the rotating rod and is sealed against the rod by conventional compressed packing. The rotary member has a cylindrical portion rotating within a cylindrical recess of the stationary member, with an annular recess defined between them. The recess contains two or more annular seal cartridges stacked one after the other in the annular space. The cartridges are designed to individually resist the ingress of the pressurized oil, so that leakage takes place sequentially past the individual cartridges. Leak passages are provided in the stationary member and are in communication with each of the cartridges respectively.  When oil appears at anygiven leak passage, this signifies that the oil has bridged the defences of thatcartridge and any cartridge or cartridges which are upstream of the leaking cartridge.
