Abstract: ABSTRACT OF THE DISCLOSURE         Lignin is obtained in a depolymerized, soluble form from various hardwoods such as aspen by a process in which the hardwood in divided form is cooked with steam at carefully selected combinations of temperature and time, within the range 170-240°C and 2-80 minutes, and then solvent extracting the cooked wood material.  It has been found that lignin undergoes a depolymerization reaction in situ in the hardwood on steam cooking, followed by a condensation and possible repolymerization reaction.  The process of the present invention conducts the depolymerization reaction but substantially prevents the subsequent condensation reactions, by careful choice of time and temperature cooking conditions.  The lignin so obtained in depolymerized form is useful as a chemical raw material.

Abstract: METHOD FOR THE SEPARATION OF FAT, PIGMENTS AND          ENTRAIL REMAINS FROM FISH RAW MATERIAL.               Abstract of the Disclosure.          The invention concerns a method for the preparation of fish mass wherein the fish meat is separated from fat, pigment and entrail remains.          The method can be utilized for fatty as well as for lean fish.  This is achieved by holding fatty or lean fish raw material in an aqueous environment, in which the pH is adjusted to pH 3-5, preferably pH 4, and in which the temperature is adjusted within the range of 20-50°C.  The fish meat with fish bones is separated from the liquid aqueous solution con-taining fat, entrail remains, and dissolved skin and abdominal epithelium and dark pigments from these, by methods known per se.  The resulting fish mass is well suited for use as raw material in the production of manufactured foods, as the fish muscle proteins are not substantially denatured by the process.

Abstract: ABSTRACT           The protective garment of the present invention primarily for use as protective athletic equipment includes protective gear for the shoulders, ribs, biceps, forearms, thighs, knees and shins.  The protective garment is generally composed of variable pressure pads, air cushions, and/or shields.  The variable pressure pad includes two superimposed plies of a light-weight, non-elastic fluid-impervious fabric material having the adjacent surfaces of the material sealed around the periphery to form a pressure tight inflatable garment which does not distend and other adjacent surfaces sealed at regions internally of the periphery to define a plurality of fluid chambers and fluid passageways.  The internal fluid chambers are fluidly communicable with adjacent fluid chambers by means of the fluid passageways.  The material crinkles and folds over at preselected regions to constrict fluid communication between the fluid chambers as an external force is applied to the variable pressure pads.  Air cusions in the form of a plurality of tubular air chambers are mounted on the variable pressure pads at certain critical locations to provide additional cushioning and dispersion of an external force over an area wider than the impact area.  Shields are mounted over the variable pressure pads and/or air cushions to provide additional means for apportioning the external force.  Vent holes are provided in the variable pressure pads and shields to permit the garment to breathe by permitting air to pass from the surface of the body and through the pads creating a chimney effect beneath the variable pressure pads.

Abstract: BALL PROJECTING APPARATUS     Abstract A ball projecting apparatus is described, including a spring biased plunger for striking a hollow ball positioned within a guide tube to project the ball out of such tube.  The ball projection apparatus is useful as a baseball hitting trainer.  An adjustment means is provided for changing the position where the plunger impacts the ball to enable the path of the ball to curve to the left or right to simulate baseball pithing.  Also the top half of the guide tube is removed to reduce its resistance to lateral spin of the ball across its direction of travel.  In one embodiment, the plunger impact position is adjusted by changing the angle of the plunger shaft relative to the ball guide tube axis. In another embodiment, this adjustment is achieved by supporting the plunger shaft substantially parallel to the guide tube axis but spaced therefrom and rotating such plunger shaft about such axis into different rotational positions relative to the center of the ball.

Abstract: HANDLE ASSEMBLY FOR MANUAL OPERATION OF                    ELECTRIC SWITCHES                ABSTRACT OF THE DISCLOSURE   A manual operating handle assembly for an enclosed switch includes a walled frame which resides within the switch enclosure and rotatably mounts a shaft. A sprocket on the shaft turns therewith to move a chain coupled to another sprocket which operates the switch or a stored-energy operator thereof. A pair of arms keyed to the shaft mounts a handle for longitudinal sliding movement toward the shaft and into the frame, and away from the shaft and out of the frame. Rotation of the handle between extreme rotative locations rotates the arms and the shaft. A contoured surface within the frame interferes with the handle in its extreme rotative locations when it is within the frame to prevent rotation thereof. Only if the handle is first slid out of the frame does it clear the surface for rotation between its ex-treme rotative locations. When the handle is between its extreme rotative locations, it cannot be slid into the frame due to interference of the con-toured surface. The handle may be locked when it is in either extreme ro-tative location and within the frame, whereat it presents a low profile, is shielded from the elements, and is virtually pryproof and vandal-proof.

Abstract: SIGNAL PEAKING METHOD AND APPARATUS                  Abstract of the Disclosure A method and apparatus is disclosed for peaking the amplitude transitions of an information-bearing signal such as a video signal.  From the video signal, a control signal and a peaking signal are developed, each having magnitude variations related to and occurring in time correlation with amplitude transitions in the video signal. The control signal is employed to modulate the peaking signal such that when transitions in the control signal exceed a threshold amplitude, the peaking signal is coupled to an output terminal at or above a given gain level, and when the transitions in the control signal are less than the threshold amplitude, the peaking signal is coupled to an output terminal at a reduced but non-zero gain level. The modulated peaking signal appearing at the output terminal is combined with the video signal to cause rela-tively high level video transitions to receive a high level of peaking and relatively lower level video transi-tions to receive lesser peaking.

Abstract: PORTABLE OSCILLATING-RING HARROW                Abstract of the Disclosure An oscillating harrow having a pair of harrow rings which can be raised and folded easily for transport.  Each ring includes a pair of opposed, central segments which are disposed below a ground-travelling frame, and a pair of opposed side segments which are mounted on the central segments for swinging between positions extending laterally and upwardly with respect to the frame.  A pair of wing members attached to opposed sides of the frame, adjacent opposed side segments, are shiftable between operative and transport positions.  The wing members are coupled to associated side segments through cables which are slack when the members are in their operative positions.  As the wing members are swung from their operative to their transport positions, slack in the cables is taken up, causing the side segments to be drawn toward the associated wing members.  The side segments are shifted thereby from their lowered, laterally extending positions toward raised, upwardly extending positions, and the two central segments are shifted upwardly away from the ground and toward the lower surface of the frame.

Abstract: Abstract For determining a path of movement of a tool along shoe bottom marginal portions a series of points along such path is selected and information regarding such points stored in the form of digitized co-ordinate axis values by computer,from which information the path can subsequently be derived. The selected points are spaced by a predetermined distance (which may be the same for each pair  of adjacent points) regardless of shoe bottom contour. To this end, when each point is digitized, the tool and shoe bottom are relatively moved apart by the predetermined distance along one e.g. a heightwise dimension (preferably an axis). Thereafter in returning the tool and shoe bottom into engagement along said one dimension and/or along a second, e.g. widthwise, dimension, movement also takes place automatically along a third, e.g. lengthwise, dimension thus to maintain the predetermined distance. Computer also has interpolation, grading (for size) and reversing (left/right) programmes.

Abstract: PHN. 9995                  10 ABSTRACT:               A pick-up and/or cutter for scanning or recording information in a track of a disc-shaped record carrier, which pick-up comprises a stylus holder, which at one end carries a stylus, and which cooperates with two transducers, one for each of two orthogonal direc-tions of vibration, each transducer being provided with a coil and an associated magnet. For each transducer the direction of movement of the coil relative to the magnet corresponds to the direction of the coil axis and the magnetic axis of the magnet, which two axes coincide, the stylus holder being connected to the moving parts of the two transducers by means of a coupling member and the coil being a flat coil. This enables the pick-up to be constructed using a transducer with larger tolerances, which is obviously cheaper.
