Abstract: The propellor guard described herein is designed primarily for the protection of manatee but is also useful in protection against injury to other animals and larger fish which might come in contact with a boat's propellor. This guard is tapered toward substantially a point at the front end and is substantially circular at the rear end so as to encircle the region in which the propellor is rotated. The guard has a V-bracket at the front which is securely pressed against a propellor support and is supported at the rear in the circular portion by a pair of clamps which engage and are bolted tightly onto the cavitation plate.

Abstract: The shield device shown herein is one to aid in soccer practice. An individual player can practice kicking a soccer ball into the apparatus and have it bounced back in his general area. The lower area of the shield comprises a back panel and two side panels connected at an angle to the back panel. Each panel is made of a sufficiently rigid material, such as a thick plywood, to absorb the impact of the kicked soccer ball. Above the panels there is a netting, such as nylon netting to guard against and intercept errant flights of the ball.

Abstract: Apparatus for crushing, grinding and shredding solid waste material in which two interacting stacks of cutting and shredding elements are positioned on two substantially parallel shafts and mounted transversely with respect to the directions of waste material fed into the apparatus. Cutting members on one stack interact with cutting members on the other stack. In each stack adjacent cutting members are spaced from each other by a spacer. The spacers in the apparatus differ from those used in prior comminutors of this type in that they also have cutter elements on their periphery and thereby serve as cutters or shredders as well as spacers. This double function of the spacers increases the efficiency of the comminuting apparatus. Most importantly there are cutting edges from the bottom to the top of each stack so that there are no intermediate elements on which strings or wires can be wrapped without encountering a cutting edge.

Abstract: The easy pour spout described herein is designed to facilitate the pouring of a fluid from its container, such as oil for the engine, power steering and transmission of an automobile as well as radiator antifreeze, without the use of a funnel. The spout is designed as a totally self-contained unit that facilitates fast delivery into the desired part of the automobile without spilling. This spout is screwed onto the individual fluid container and after the spout and container are positioned for delivery, the delivery is actuated by a downward thrust on the container and spout.

Abstract: The process, described herein comprise stapling a patient's mesentery and omentum with two, three or four rows of staples, the rows being substantially parallel to each other, the staples in all the rows having the same crown size with alternate rows staggered one-fourth of the length of each crown with respect to the adjacent crown in the adjacent row or rows of staples. Advantageously the prong lengths in at least one row differ from the prong lengths in the other row or rows. Advantageously the longer prongs are 30-100 percent larger, preferably about 33-75 percent larger than the smaller prongs. This arrangement is capable of satisfactorily sealing off the variety of sizes of blood vessels and holding firmly the fatty tissue found in the mesentery and in the omentum.

Abstract: This cam has a cam lobe having opposite sinusoidal surfaces which have two rises and two reverse rises or two dips in 360.degree. of each sinusoidal surface with the rises in one such surface being opposite to the reverse rises in the other such surface, which sinusoidal surfaces will have full, centerline contact with a pair of bearings attached to the same connecting rod connected to a pair of pistons, these bearings being on opposite sides of the cam lobe and at one time being driven in one direction by one of the two pistons in each pair and then at another time in the opposite direction by the other piston in that pair. The surfaces of the cam lobe avoid friction or binding between the cam lobe surfaces and across the width of each bearing continuously through each revolution of the cam and of each bearing.

Abstract: The lock security device described herein is designed to prevent the turning of the lock from the opposite side of the lock, for example, by the turning of a key from the outside or opposite side of the lock. With most dead bolt door locks there is a knob on the inner side of the door by which the bolt of the lock may be moved forward into a locking position or retracted into an unlocking position. These same actions may be performed by a key inserted into the lock from the outside of the door. The security device is a simple knob on the inner side of the door with a flap which may be turned to press against the inside knob which controls the position of the bolt of the lock. When the bolt is in locked position, this flap is turned toward the bolt controlling knob and engages it to prevent turning of the same into an unlocking position. This flap is prevented from slipping to or from this engaging position by a spring on the inside of the flap knob which exerts pressure against the turning of this flap.

Abstract: The stapling processes described herein comprise those suitable for stapling a patient's mesentery and omentum with three or four rows of staples being substantially parallel to each other and the staples in one row being staggered with staples of the same size in another row, there being at least one row in which the staples differ in size from the staples in the other rows. Advantageously the larger staples are 30-50 percent larger, preferably about 33 percent larger than the smaller staples. Also advantageously the smaller staples are similar to those presently used as vascular staples, in the range of 2.5-3.5 mm, preferably about 3 mm, and the larger staples are advantageously in the range of 3.5-4.5 mm, preferably about 4 mm. This arrangement is capable of satisfactorily sealing off the variety of sizes of blood vessels and holding firmly the fatty tissue found in the mesentery and in the omentum.

Abstract: Mechanism primarily suited to automatic sliding door applications wherein at least a pair of object presence sensing detectors, preferably of the ultra-sonic transducer type are arranged to be placed in linear spaced relation to one another effective to cast sonic beams produced thereby spanning the doorway to which applied. So as to assure satisfactorily a beam path to be intercepted by an object stationary or moving in the beams, they are purposely overlapped. The door upon being operatively moved by motion sensing detectors or manual means acts at different opening positions to switch the object sensing detectors on and upon reverse closing positions switches the object sensing detectors off.

Abstract: The sailboat control device disclosed herein comprises one actuated by the pulling of a pin positioned therein, whose removal therefrom permits a spring controlled switch to be closed so that the position of the boat rudder is determined by the maneuvering of a wind vane on the boat. A line connected at one end to said pin and at the other end to the sailor on board causes the pin to be pulled or removed from the said device if and when the sailor should fall overboard. Movement of the wind vane and accompanying rotation of the vertical shaft to which it is attached effects movement of the rudder to make the boat travel in a direction not too far from where the sailor has fallen overboard.
