Abstract: A motor operated valve, typically a butterfly valve driven by a synchronous electric motor (16) is provided with a torque sensing arrangement wherein an cyclic electrical signal representative of the rotational speed of the motor is produced by magnets (22) on disc driven by the motor and Hall effect switches (23, 24). The frequency of this signal is compared in a circuit (43) with the frequency of current supplied to the motor to provide an indication of motor torque. Switches (46, 47) define preset torque limits for the valve. If the limits are exceeded a signal is fed to control logic (41) which operates switches (18) to control the supply current to the motor. The speed signal from the Hall effect switches is also fed to a converter (33) to develop a counter representative of movement of the valve. The output of counter (33) is compared with preset valves defined by switch circuits (37, 38) to define limits of travel for the valve.

Abstract: Compositions labeled with technetium-99m and suitable for administration to patients are purified by means of a filtration column conveniently in the form of a syringe body (10) purged of oxygen and sealed at its opposite ends. Retained by fluid-passing plugs (14, 16) in the syringe body is a particulate substrate (12) such as cross-linked dextran which is capable of binding reduced technetium (lV oxidation state) and of retaining insoluble technetium moieties such as reduced hydrolysed technetium. The substrate (12) contains a reducing agent prepared in the absence of oxygen and comprising a mixture of colloidal stannous phthalate and an antioxidant such as gentistic acid. In use, a needle is attached to one end of the syringe body in place of one seal and the composition to be purified is drawn therethrough into and through the substrate by means of a second syringe, the needle of which is inserted through a closure seal (20) at the second end of the substrate-containing syringe body.

Abstract: For a controlled positioning of a read element relative to a track to be read during the read-out of such a record carrier, low-frequency tracking signals may be recorded in the tracks. Instead of adding separate tracking signals to the information signal, these tracking signals are represented by the d.c. content of the information signal. During conversion of the information words of the information signal into channel words steps are therefore taken to provide two channel words whose d.c. content is equal but opposite for each information word. The choice between these two channel words is made depending on a control signal which depends on the desired tracking signal.

Abstract: Every link member is composed of individual link member disks having designs different from each other. All link member disks have tongues and projections projecting above these tongues, which projections comprise thrust surfaces. The link member disks of every link member abut each other via these thrust surfaces and the two outermost link member disks of every link member are intended to abut via their thrust surfaces the conically extending surfaces of the driving disks of an infinitely variable transmission having disks looped by a flexible belt. The link member disks of every link member have different thicknesses viewed in the direction of the pivot pins which penetrate the tongues. The succession of the various link member disks of every link member can be varied at each link member such that it is possible to assemble a link belt such that it produces in operation extremely small noise in consideration of the prevailing operational conditions such as speed, power transmitted, distance between the two driving disks, etc.

Abstract: An industrial process for producing polyols comprises subjecting sugars to aerobic fermentation using Moniliella tomentosa var pollinis in a fermentation medium containing a water-soluble or water-dispersible polymer which is capable of retaining the cells in the fermentation medium. The process is especially suitable for the industrial production of erythritol and/or ribitol. The process overcomes the disadvantage shared by prior proposals wherein cells are lost from the fermentation media through being carried away by the foam produced during fermentation.
