Abstract: Manifolded Multiple Hydraulic Pump Structure Abstract An improved hydraulic pump structure for hydraulic systems which require a plurality of rotary pumps has a pump casing assembly consisting of a plurality of pump casing elements which are fastened together in abutting relationship to define a first pump cavity and a second pump cavity with aligned drive shaft holes and a drive shaft which is journalled in the holes and carries a rotary pump member in each cavity.  The casing elements are manifolded to provide a first fluid inlet passage, a first fluid delivery passage which terminates in a port in a fluid delivery end plate, a second fluid inlet passage which has an entrance opening in the fluid delivery end plate, and a second fluid outlet passage which terminates in a port in the fluid delivery end plate.  There may be two subassemblies with two pumps in each, secured together in face abutting relationship with an axially interengaged driving connection between drive shaft segments in the two subassemblies and with fluid delivery passages extending from one assembly through the other.

Abstract: Abstract Thixotropic magnesium-containing complexes are prepared by heating a mixture of magnesium hydroxide, mag-nesium oxide, hydrated magnesium oxide or a magnesium al-koxide; a sulfonic acid, a pentavalent phosphorus acid, a mixture thereof with a carboxylic acid, or an ester or salt of any of these; water (optional under certain conditions) and an organic solubilizing agent (which may be liquid or solid at ambient temperature) for the acid or ester.  The amount of magnesium is such as to provide a basic compo-sition.  The resulting complexes may be obtained in liquid or solid form, and are useful as additives for lubricants and fuels and as protective coating compositions for metal surfaces (such as automotive undercoats and frame coatings).

Abstract: ABSTRACT OF THE DISCLOSURE       A method of producing a plate-shaped body, particularly a video disc in which circumferential warp in the thicknesswise direction, thickness fluctuation, and deflection of the signal track are minimized comprising the steps of pressing in a mold a thermoplastic resin which has been heated to a temperature above the softening point thereof, and cooling the thermoplastic resin to solidify the same.  During the cooling, the pressure of the mold is decreased to a low level when the thermoplastic resin has been cooled down to a temperature around the softening point thereof.  The thermoplastic resin is allowed to be solidified without any substantial and local residual stress to ensure minimal circumferential warp, thickness fluctuation and deflection of the signal track.

Abstract: IN THE PATENT OFFICE                   APPLICATION ENTITLED         "Method and device for anchoring rods of insulating material in attachment fitting"      in the name of : Pierre VIENNOT ABSTRACT OF THE DISCLOSURE A method and device for anchoring rods of high tensile strength insulating material in metal attachment fittings are disclosed. The end of the rod which is previously split and traversed by a hole is inserted axially into the attachment fitting through an open end thereof. A fastening member is inserted into a blind hole extending across an internal cavity in the attachment fitting in line with the hole in the rod for spreading the rod end, the split end being brought into engagement with large wall portions of the inwardly flaring internal cavity of the attachment filling. A relatively high vacuum is applied to the internal cavity. The internal cavity is filled with a high strength, nonshrinking resin having a coefficient of expansion identical to that of the metal fitting through a channel in the fastening member. After polymerization the resin hardens on the rod to form a rigid block fast with the attachment fitting which pre-vents the rod from being pulled out of the attachment fitting. The protruding end of the fastening member is then severed level with the exterior of the attachment fitting.

Abstract: ABSTRACT OF THE DISCLOSURE                               where X is Na+, K+, Li+, NH4 or H (N-phosphonacetyl-L-aspartato) (1,2-diaminocyclohexane)platinum(II) or alkali metal or ammonium salt thereof has shown antitumor activity in animals such as activity against murine leukemia L1210. Additionally, this agent is used against B-16 and Colon 38 tumors and also Ehrlich ascites tumor. It is effective in dosages of 5-60 mg/kg of body weight and is potentiated in a treatment with cyclophosphamide (CY) (50 mg/kg of body weight) to which may be added hydroxyurea (HU) (1000-1500 mg/kg of body weight).  In binary treat-ment with cis-dichlorodiamineplatinum(II) (or cisplatin) the preferred ratio of the present compound to cisplatin is about 10:1 with a range of about 10:1 to 1:10 in mg/kg of body weight. The present platinum compound may be pre-pared by reacting the known L-aspartic acid, N-(phosphonacetyl-)disodium salt (PALA; NSC-224131), with dinitrato(1,2-diaminocyclohexane)platinum(II) (NSC-239851). This compound N-phosphonacetyl-L-aspartato (1,2-diaminocyclohexane) platinum (II) may be combined in multiple drug regimen with substantially improved yield cures over the parent compounds. For example, the compound denoted Pt-268 may be combined in a dual regimen with cyclophosphamide (CY), hydroxyurea (HU), and cisplatin.

Abstract: HYDRAULICALLY ACTUATED APPARATUS               Abstract of the Disclosure A multipurpose, hydraulically actuated apparatus comprising a piston movable in response to fluid under pressure within walls defining a piston chamber.  Actuating fluid is supplied to the piston chamber by a uniquely constructed hand operated fluid pump.  The area of the fluid impinging surface of the piston is in multiples of one inch.  Accordingly, when the apparatus is used as a hydraulic scale the weight being lifted by the piston can be read directly on a pressure gauge which is calibrated in pounds per square inch and which is connected to the piston chamber below the piston.          The apparatus can readily be converted to function as a cutting device for use by a plumber in cutting nuts and the like in situ by connecting a U-shaped member to the walls of the unit and by connecting a cutting element to the outer face of the piston.  The U-shaped member includes spaced apart arms and a bight portion defining a closed space adapted to encircle the nut which is to be cut.  Pressure exerted on the piston will cause the cutting element to move toward the bight portion of the U-shaped member and into pressural engagement with the nut.          A unique pressure tight swivel coupling is provided in the conduit interconnecting the hand pump and the piston chamber so that the latter can swivel freely relative to the hand pump.            A further novel feature of the apparatus of the invention comprises an air tight, fluid carrying collapsible liner which is housed within the hollow body of the hand pump.  The hollow body of the pump is vented to atmosphere but the liner is sealably carried therewithin so that the fluid within the liner cannot escape to atmosphere through the vent.  With this arrangement, as fluid is withdrawn from the hand pump and forced into the piston chamber, air will enter the hollow body causing the liner to collapse.  However, because the liner is sealed relative to atmosphere it will effectively prevent air or other contaminates from intermixing with the fluid.
