Abstract: A B S T R A C T            At the end of a crane arm on a base vehicle is fixed a frame, the inclination of which is controlled by double-acting hydraulic cylinders, and which supports hydraulically operated grip arms and a cutting unit. The frame is with a estimated inclination moved against a tree and the grip arms urge  the frame to conformance with the actual inclination of the tree, thereby inducing strains in the tree as well as the firmly based crane arm. A valve connect-ing the inlet and outlet of each hydraulic cylinder is momentaneous-ly opened from its hitherto closed position, so that the fluid in the cylinder is forced to equalize under the strains from the biased tree which consequently will be relieved from tension before cutting, otherwise resulting in cracks in the root end of the tree.

Abstract: PSEUDO HALFTONE PRINT GENERATOR AND METHOD          Abstract Gray scale levels are converted to pseudo halftone print by a pseudo halftone generator which reduces Moire effects.  The generator includes a comparator and an incrementing cyclic count-ing mechanism to compare the gray scale level to the cyclicly generated reference count for each print position in a print line to generate a print signal upon the level being greater than the count.  The cyclicly generated count is incremented by a preselected number N for each print position and recycles at the square of that number (N2).  The square value may also be selected as the maximum level of the gray scale range.  N adjacent print lines may be grouped together to form a series of (NxN) matrices.  The refer-ence or lowest count value for each of the lines in a matrix is different and they range from zero to N-1.  The arrangement of the lines in the matrix is such as to minimize the difference be-tween the sums of the count element values for any two adjacent print lines.  The count for each generator is initialized at the beginning of the print line and may be established randomly for each print line or, alternatively, for each matrix of print lines, the matrix being arranged in a predetermined manner.

Abstract: "DRAFT GEAR REMOVING DEVICE"                 Abstract of the Disclosure A hydraulic extractor and its use in removing damaged draft gear which are wedged in railway cars.  It consists of a length of pressure resistant hose folded at its center to lie flat upon itself when empty, and having connections at both ends for receiving hydraulic fluid under pressure.  Also included is an arrangement for feeding the hose into the restricted space above the draft yoke and below the draft sill.  That arrangement comprises a pair of strips of sheet metal of a width generally the same as that of the flat hose, and means connecting the strips together at one end.  The hose is placed between the strips, with the fold near the connecting means.  A rudimentary winch is pro-vided for connection by a cable to the metal strips where they are connected.  In use, the cable is fed through the space to be expanded, and connected to the winch, and the hose in its pro-tective metal strips is winched into the desired location.  When hydraulic fluid under pressure is forced into the hose at both ends, it expands laterally, driving the draft yoke and draft gear downward and out of the pocket.

Abstract: AIR CUSHION GAME                    ABSTRACT OF THE DISCLOSURE     The present invention is a game to be played on an air cushioned table of specific design. The table includes an air bed with a perforated surface to which air under pressure is supplied from below creating a multiplicity of closely spaced air jets upon which a game piece floats. Scoring areas are disposed at opposite ends of the air bed and may include one or more different types of scoring patterns applicable to game play. A player pushes a game piece from one scoring area towards the other scoring area whereby the game piece passes over the air bed with the frictional  drag thereon being significantly lower than that of the scoring area towards which the game piece is urged. The air bed and scoring areas are supported by frame means and are bounded by gutter means and outside border means for respectively receiving the game piece should it fall off the air bed or scoring area and for retaining the game piece on the table.      The hole the air bed may be located in various arrange-ments so as to impart various movement characteristics to a game piece passing thereover. In addition air escape grooves are provided in the air bed surface for releasing a portion of the air cushion supporting a game piece so that movement of the game piece is distorted which in turn increases the interest and challenge in playing the game.

Abstract: ABSTRACT OF THE DISCLOSURE             In a corrugated metal sheet of the type that is adapted to have the edges of recesses which are located at the crests of the corrugations engaging a tube for establish-ing heat transmitting contact between the metal sheet and the tube, each recess in the metal sheet is so much smaller than the geometrical figure inscribed by the line of engage-ment between the metal sheet and the tube that an annular edge portion will be formed between the recess and the line of engagement.  As a result, the recess despite manufacturing inaccuracies will bear with the whole extent of its edges against the tube, the excess material at the edges of the recess being brought to form an edge flange facing the tube.           The corrugated metal sheet is manufactured from a strip which is advanced stepwise in the corrugating operation.          The recesses are punched in the metal sheet before the corrugating operation, the punching being effected between the steps of advancing the metal sheet.  The corrugations are also given their final shape between the steps of advancing the metal sheet.  Between the steps of advancing the metal sheet, the excess material at the edges of the recess in a finished corrugation is shaped into the edge flange which is to engage the tube.

Abstract: METHOD FOR THE PRODUCTION OF ALPHA-TYPE HEMIHYDRATED GYPSUM      ABSTRACT OF THE DISCLOSURE         Alpha-type hemihydrated gypsum is obtained by suspending gypsum in an aqueous solution containing a specific monocarboxylate selected from magnesium salts and zinc salts of lower monocarboxylic acids having 1 to 4 carbon atoms in a concentration of not less than 10% by weight and heating the resultant suspension in a specific temperature range under atmospheric pressure.  The production of this alpha-type hemihydrated gypsum is accomplished at an increased rate by adding a monocarboxylic acid having 1 to 4 carbon atoms to the aqueous solution, suspending gypsum in the resultant solution and heating the resultant suspension under the atmospheric pressure.  By this means alpha-type gypsum hemi-hydrate can be produced by an efficient method which does not require the use of expensive pressure vessels.

Abstract: MODULAR SPLIT SCREEN HYDRO-EXTRACTOR            ABSTRACT OF THE DISCLOSURE     In a hydro-extractor, a screw is disposed with an outer concentric cylindrical sieve.  The sieve is formed of sections placed lengthwise of the screw, with each section capable of having the same or different size holes so that the extractor captures solids both large and small in a controlled manner and will dewater faster or slower with various combinations of sieve sections.  Where a sieve section contains smaller size holes of higher density per unit area and is constructed of relatively thin gauge material, an outer back-up screen of thicker gauge material with large holes is utilized in order to support the thinner screen and cooperate in withstanding the pressures generated during dewatering.   Therefore, modu-lation of the sieve sections may be accomplished both vertical-ly and horizontally.
