Abstract: A reduced area, night playable golf course is achieved by utilizing a common driving area for all par 4 and par 5 holes on the course. Separate laterally spaced tees are provided at one end of the driving area for each hole. The ball landing region of the driving area is covered by a grid of ball catching nets having relatively small areas. A ball caught by a particular net is directed to a ball return conduit which includes a ball actuated switch which inputs a signal to a computer which records the distance and lateral position of the ball as two coordinates which are printed on the player's score card. The playing course is conventionally constructed, except that the initial 100 to 150 yards of each par 4 and par 5 hole is omitted. A grid pattern of markers bearing coordinates corresponding to those of the ball catching nets is installed in the initial portions of the par 4 and par 5 holes and the ball is dropped for the second shot adjacent the marker showing the coordinates of the drive.

Abstract: A train of signals is generated by clocking an 8-bit word from an 8-bit shift register which has been loaded with an initial data word. The register is provided with feedback loop. The serial data is supplied along a communication link to a similar or identical 8-bit shift register at the receiving end of the link. A comparator compares the output data of the register with the first stage of the register and provides an accept signal provided such comparison indicates inversions at the receipt of each bit for 9-bits onwards. After transmission of 24-bits, the shift register contains the 8-bit data word, which has been checked twice for any inaccuracy.

Abstract: An oil separation method and apparatus for the continuous separation of acceptable oil from contaminated oil containing solids and liquids withdrawn from an oil well. Three separate settling tanks are partitioned and provided with skimmers, as appropriate, to enable contaminated oil to dwell sufficiently within the tanks. After sufficient dwell time, the skimmers remove separated oil from the top layer and move it to an oil tank. Liquids such as water and emulsified oil are separated into an intermediate layer and moved to further settling tanks to provide sufficient dwell time for oil separation and collection. The first settling tank has a rotating jet spray header for agitating the solids accumulated in the bottom of the first tank and a series of suction headers for withdrawing the solids without interruption of the top oil layer or the separation operation.

Abstract: An assembly for converting the one-directional power transmission of a conventional power ratchet wrench into alternating transmission of the power to the wrench's driver head in both the clockwise and counter-clockwise direction without moving the rotational direction selected by the wrench's rotation direction selector subassembly from a first selected position. A scraper attachment attaches to the driver head of the wrench and an engagement arm connects the body of the attachment directly and tightly to the ratcheting section of the wrench. A scraper blade is pivotally connected to the body of the attachment and extends in a generally perpendicular direction from the axis of rotation of the body member. Operation of the wrench results in oscillating arcuate rotation of the scraper blade as it is pressed upon the surface to be scraped.
