Abstract: ABSTRACT Materials formed from plaster gypsum mixtures have not been used as load bearing materials due to their loss of strength when contacted with water.  It is known to coat such materials with water-repellent but this requires an additional drying step.  Additionally such a coating leads to a product which does not have uniform properties over its entire surface.  As a result there are no commercial process for manufacturing load bearing water-repellent plaster-gypsum objects.  The present invention overcomes this draw back by providing a process for preparing a water-repellent material from a gypsum plaster mix comprising mixing in any sequence plaster and gypsum, to provide a mixture comprising from about 30 to about 99% by weight plaster, water in an amount to provide an excess of up to 15% over the stoichiometric amount required for the setting of the gypsum plaster mix; and from about .2 to 2% of a water-repellent agent which is at least one metallic salt of a long chain fatty acid; placing the resulting mixture in a mould and subjecting it to a pressure of up to about 700 kg/cm2 for a time sufficient to cause the mixture to retain the shape of the mould, and removing the mixture from the mould without drying.

Abstract: TIME DELAY SWITCH ACTUATING MECHANISM  Abstract of the Disclosure A time delay type of switch actuating mechanism is shown that can be assembled for either an "on delay" or "off delay" operation. A pair of contact carriers are mounted for linear motion, and a pivoted rocker member is joined between them for coordinating their movements.          The rocker member has a lost motion connection with each contact car-rier, and a catch is provided to restrain movement of the rocker and contact carriers until a timer performs a timing function. At the end of the timing interval the catch is released to permit a loaded spring to move the contact carriers and rocker to complete a switching function that is time delayed. Besides a desired linear motion and a unique ar-rangement in a base housing the switch actuating mechanism also pro-vides for the test operation of switch contacts in a time delay relay.

Abstract: ABSTRACT OF THE DISCLOSURE    In a computerized tomographic apparatus of the kind in which the performances of different detectors is normalised by causing them to receive radiation along substantially similar paths in various overlap zones within a body under examination, the normalisation can be adversely affected by the amount o radiation exposure suffered by each detector prior to its receipt of radiation along the paths in the overlap zones.   The invent-on permits such adverse effects to be reduced or eliminated by averaging the electrical signals, produced by the detectors in respect of the paths in the overlap zones; the signals relating to paths near the centre of an overlap zone being combined with the signals relating to other paths distributed substantially across the overlap zone but the signals relating to paths near the edges of an overlap zone being combined with the signals relating to only a few, neighbouring, paths.

Abstract: IMPROVED DUAL TRACTOR ROAD GRADER     ABSTRACT OF THE DISCLOSURE       A double arch center frame employs a depending center arch to mount by a bail and socket connection the leading end of a draw bar and yoke assembly.  Bell cranks pivotably mounted to yoke plates borne by the arched center frame intermediate of the center arch and the rear arch have arms pivotably coupled to respective hydraulic lift cylinders disposed on opposite sides of the center frame and to a link member common to the bell cranks. A side shift hydraulic cylinder is pivotably connected at one end to one side of a subframe rotatably supporting a mold board assembly and at the other end to said link member intermediate of its pivot connections to said second arm of the bell crank members.  The hydraulic lift cylinders are coupled at their opposite ends to respective sides of the subframe such that like extension and retraction of the hydraulic lift  cylinders causes the subframe and the mold board assembly to be vertically raised or lowered; extension or retraction of only one of the hydraulic lift cylinders with respect to the other causes the mold board assembly to be tilted in the plane of the longitudinal axis of the mold board, and extension or retraction of the side shift hydraulic cylinder causes the subframe and the mold board assembly to be shifted laterally with respect to the longitudinal center line of the center frame.          The forward arched end of the center frame is articulated to a front single axle  tractor for rotation about right angle, vertical and horizontal axes, and the rear arched end of the center frame is hinge connected to a rear single axle  tractor for pivoting about a horizontal axis.  Multiple hydraulic crab steering cylinders force angulation of the tandem wheel tractors relative to respective ends of the double arch center frame to move the unit selectively into laterally offset crab steering conditions for the dual tractors for soft ground grading.

The sheath is stripped back to expose a portion of the second screen, a portion of the first screen and an intermediate length of the insulating layer, the second screen also being stripped back to expose such intermediate length and the layer being stripped back to expose such portion of the first screen.  The sealing end comprises a hollow, cylindrical container extending lengthwise of the cable and from adjacent the bared con-ductor end to adjacent the sheath.  The inner diameter of the container is larger than the diameter of the cable, preferably at least twice the diameter of the insulating layer, and the container end adjacent the sheath has a liquid tight connection to the sheath.  The container is filled with liquid having a resistivity in the range from 108 to 106 ohm-meter, and the liquid is prevented from contacting the bared conductor end.  One end of the liquid is conductively connected to the bared conductor end and the other end of the liquid is conductively connected to the sheath, the length of the container, and hence, the liquid, being sufficient to withstand the cable voltage between the conductor and the sheath.  The conductor end and the insulating layer may be covered with tapes to prevent contact of the liquid therewith.

Abstract: ????     STABLE DEHYDRATED COCRYSTALLINE    AMINO ACID FOOD ADDITIVES                    Stephen A. McCoy and James L. Bono Abstract This invention relates to improved nutritionally useful, amino acid food additives, the method of making them and the fortification of foodstuffs which are deficient in the nutritionally related amino acids. This improved amino acid food additive comprises: a uniform dehydrated cocrystalline matrix of (1) an amino acid material, preferably a salt of an essential amino acid material, and (2) an effective amount of a soluble edible cocrystallizer material, preferably sodium chloride, whereby the improved amino acid food additive provided is better-tasting, more stable and less hygroscopic than the free amino acid material alone.  A preferred improved amino acid food additive is made by dissolving 118 grams of L-lysine hydrochloride, 62 grams of N-acetyl L-methionine (NALM), 42 grams of L-threonine and 240 grams sodium chloride into 800 grams of water at 150°F.  The salts of L-lysine, NALM and L-threonine are provided by neutralizing the solution with sodium hydroxide to a pH of 6.8.  Then the solu-tion is freeze dried to provide a stable dehydrated uniform cocrystalline matrix of the salts of said amino acids and NaCl.  Peanut butter fortified with this improved additive is more stable and better tasting than one made with free amino acids.
