Title: Combined belt and hydrostatic vehicle drive

Abstract: COMBINED BELT AND HYDROSTATIC VEHICLE DRIVE              Abstract of the Disclosure A self-propelled combine has a power source that is con-nected to a hydrostatic drive for the drive wheels by means of a belt drive, that includes a pair of coaxial idler sheaves mounted on a freely swingable arm, one sheave being connected to an input sheave by a first belt and the other idler sheave being connected by a second drive belt to an output sheave that drives the pump of the hydrostatic drive.  The arm that mounts the idler sheaves is articulated, and a hydraulic cylinder between the two sections of the arm controls the distance between the idler sheave axis and the arm pivot, which in turn controls the tension in the two belts. The hydraulic cylinder is connected to the high pressure side of the hydrostatic drive so that the cylinder exerts a belt tensioning force that is proportional to the pressure in the high pressure side of the hydrostatic drive, whereby an increase in pressure in the hydrostatic drive as a result of increased torque required to propel the combine increases the belt tension in the belt drive.

Abstract: COMBINED POWER AND MANUALLY ACTIVATED BRAKE SYSTEM          Abstract of the Disclosure A brake system is disclosed which comprises a primary fluid power brake subsystem and a secondary or back-up brake subsystem.  The primary brake system is of the "power brake" type, and includes a power brake valve having a housing defining an elongate bore.  A bi-ended rod extends through the housing end wall to be slid between spaced apart first, second and third positions.  That end of the rod which is inside the housing is affixed to a reaction piston.  The reaction piston cooperates with an annular piston, also carried within the bore, to have fluid flow through the valve and raise fluid pressure within a collapsible chamber defined by the bore.  When the rod is partially pulled out of the valve housing, this high pressure fluid is directed to vehicle brakes to cause primary braking action.  Should the primary system fail in some respect, rod pull-out action operates to energize a secondary or back-up brake system.  Secondary brake system energization is caused by a brake controller which is connected to the primary valve rod, and which is also positioned to engage a secondary brake sub-system master cylinder actuator.

Abstract: ABSTRACT     Apparatus and method for luminescent determination of concentration of an analyte in a sample The apparatus comprises a movable member which carries a plurality of cuvettes containing material under test.  Control means cause the member to be moved to bring the cuvettes successively into register with a photomultiplier, and in that position reagent is automatically added to a cuvette, giving rise to a luminescent reaction.  Light from the reaction is detected by the photomultiplier and the resultant signal processed and recorded.  The control means is triggered to stop the member, add reagent, record the signal from the luminescent reaction, and restart the member, from a photocell which is illuminated through the member only when a cuvette is in register with the photo-multiplier.     According to the method, sample material containing the analyte for determination is mixed with a knot amount or concentration of the same analyte labelled with a substance which is capable of taking part in a luminescent reaction.  The mixture is then reacted with a known amount of another substance, capable of reacting with the analyte and giving rise to a luminescent reaction with the labelling substance. From quantitative observation of the light from the luminescent reaction the amount or concentration of the analyte in the sample material may be deduced.

Abstract: ABSTRACT OF THE DISCLOSURE     Potassium magnesium phosphate can be produced without the application of special and technologically expensive measures and without the use of supplementary substances, while proceeding from easily available starting materials.          Potassium  magnesium phosphate is prepared by reacting acidic aqueous solutions containing phosphate ions with potassium chloride and with alkaline magnesium compounds.          According to the method, an alkaline magnesium compound in the amount stoichiometrically required to yield dimagnesium phosphate and part of the required total amount of potassium chloride was introduced under stirring into an acidic phosphate solution, having a P205 content of 20 to 167 g of P205 per 1000 g of water and, following addition of the residual amount of potassium chloride, whereby the total amount of potassium chloride added is increased to a molar ratio of K20 :P205 of more than 1 : 1, which is slightly below the saturation concentration.  The alkaline magnesium compound is slowly introduced into the resulting suspension, at a  temperature below 40°C, in the amount stoichiometrically required to form tertiary magnesium phosphate, whereby a concentration of 130 g of MgC12 in 1000 g of water in the reaction mixture is not exceeded.  Then the product is separated from the mother liquor, washed with water and dried.  The method according to the present invention flows from the discovery that potassium magnesium phospate it metastable in the presence of soluble salts of magnesium, particuarly of magnesium chloride, and that it forms trimagnesium phosphate in such solutions according to the formula 2KMgP04 + MgC12 = Mg3 (P04)2 + 2 KC1
