Abstract: POWER DRIVE UNIT AND CONTROL         SYSTEM THEREFOR                        Abstract A power drive unit and control system there-for avoiding performance degradation which can occur in control of the variable displacement hydraulic motor of the power drive unit by measurement of the angle of a displacement-setting wobbler of the motor and the speed of the motor.  This is avoided by sensing flow through the motor which provides an indirect measure of wobbler position and speed of motor operation.              The power drive unit and control system therefor has a variable displacement hydraulic motor with a displacement-setting wobbler positioned by pres-sure applied to a servo piston by an electro-hydraulic servo valve.  The control system responds to a speed command having a value dependent upon a position loop which determines the relation between the actual posi-tion of a load and a commanded position, with the con-trol providing for a maximum possible speed of motor operation under a particular load condition with a sub-stantially constant rate of fluid flow through the motor.  As the load varies, the flow through a flow-regulator valve varies and flow is sensed by a linear variable differential transformer associated with the valve member of the flow regulator.  The linear variable differential transformer outputs a control voltage in-dicative of a variation in either direction from the desired rate of fluid flow through the motor which is used to adjust the angle of the wobbler to bring the flow to the desired rate and the motor is caused to operate at a maximum possible speed.  The control, by using a speed command responsive to a position loop, provides a controlled snubbing action to reduce the speed of the motor as the load approaches the commanded position.

Abstract: Abstract:    A process of directly converting natural gas to methanol employs controlled oxidation.  The reaction takes place in an inert reactor, i.e. one having internal surfaces which do not affect the reaction, in the absence of a catalyst.  The natural gas is intimately mixed with air or oxygen prior to introduction of the mixed gases into the reactor.  Reaction takes place at an elevated temperature of 300 to 500°C and at an elevated pressure of 10 to 100 atmospheres.  The percentage of oxygen in the mixture of reactant gases is kept below 20% by volume and is preferably 2 to 10% by volume.  Apparatus for carrying out the method is also provided.

Abstract: VOLTAGE REFERENCE FOR TRANSISTOR                   CONSTANT-CURRENT SOURCE           Abstract of the Disclosure A voltage reference circuit (10) for a constant-current source transistor (16) of the bipolar type provides an output voltage in two components.  The first voltage component varies in accordance with the negative temperature coefficient (C1) of the base (58)-emitter (78) junction of a bipolar transistor (60) to compensate for temperature-related changes in the base (18)-to-emitter (22) voltage of the constant current source transistor. The second voltage component is of fixed magnitude and develops collector current (IO) flow through the transistor and thereby actuates constant-current source operation.  The result is a transistor constant-current source that provides a constant output current independent of temperature.

Abstract: A top shoot protector 1 is described.  The top shoot protector 1 comprises a protective stake 3, which runs parallel with and along a stem 2.  The top shoot 5 of the stem 2 is to be protected against biting or breaking off. This is achieved in that the upper end of the protective stake 3 extends upwards past the top shoot 5.  The protective stake 3 is fastened by means of clips 4.  Each clip has a first and second U-shaped profile 9, 14, which are designed for sprung snap engagement around the protective stake 3 and the stem 2 respectively.  The protective stake 3 is of small dimensions and will therefore not adversely affect the light reaching the needles 8 of the tree or of the actual top shoot itself. Since the protective stake 3 is thin, birds will not endeavour to perch on this, but will instead seek another place to land.  The protective stake furthermore prevents biting off of the top shoot, since the upper part of the protective stake runs along the top shoot. <IMAGE>

Abstract: On preparation of parenteral solutions for the treatment and prophylaxis of thromboses and embolisms to date it has been necessary, because of the poor solubility of t-PA, either to infuse very large volumes or else prepare a solution with a low volume and high t-PA concentration by adjusting to a low, non-physiological pH of 2 to 5. The invention therefore relates to a process for preparing a solution of high specific volume-based activity of a protein with plasminogen activator activity, achieving an increase in stability and solubility by adding at least two substances from the group of D-and/or L-amino acids, the salts, derivatives or homologues thereof, and to a process for pasteurising a protein solution with t-PA activity and to the use of this solution as fibrinolytic in human and veterinary medicine.
