A golf practice device includes a base plate, a support shaft inclined from the vertical and extending upwardly from the base plate, and a golf ball support arm slideably adjustable along the support arm. For the best method of practicing the swing, the length of the support arm and support shaft are such that a golf ball at the end of the support arm may be positioned at a distance between 20 and 40 centimeters above the base plate, where it will be struck by the golfer. Since the support shaft is inclined from the vertical, the support are will always automatically return the golf ball to the same location above the base plate.

An apparatus for forming a fiber reinforced slab gel for use in electrophoresis including a box shaped casing having a first groove at the center of an inner lower end surface, and a cover having a second groove for hermetically closing an open area of the casing. A plurality of slab gel forming plates are laminated in the casing with fiber reinforced cores interposed between adjacent slab gel forming plates. An aqueous solution of an organic monomer is poured into the casing through a pouring pipe in the cover and the monomer is polymerized to form the gel slabs. Air in the casing is vented to the outside when the monomer is introduced into the casing.

A narrow neck bottle is washed and rinsed by a method comprising the steps of supporting the bottle in an upside down position, injecting water containing air bubbles, into the bottle through a tube extending through the narrow neck of the bottle, accumulating air released from the poured water in an upper space in the bottle and expelling air and water remaining in the bottle by the accumulated air. Apparatus for carrying out this method comprises an aspirator installed such that its discharge pipe is directed upwardly, and connected to the discharge pipe, and a support for supporting the narrow neck bottle such that when supported by the support, the narrow neck of the bottle engages against the tube and that a gap is formed between the inner bottom surface of the bottle and the free end of the tube.
摘要:
An open top electrode tank including two electrode chambers respectively containing an electrolyte and an electrode, and an open top cooling tank containing cooling fluid are superposed one upon the other. A separating zone is attached to the bottom of the cooling tank, and bent portions of a pair of bridging filter papers are attached to predetermined positions of a separating zone. Permanent magnets are disposed on both sides of each filter paper and on the bottom of the cooling tank for attracting each other.
