Abstract: ABSTRACT     A fall arrest device for a pole climber which has a main yoke with a respective spring biased arm at each end for partly encompassing a pole.  The resiliently biased arms are movable in the same plane as the main yoke and also urge secondary yokes into contact with the pole to accomodate a range of pole diameters.  Handles are attached to each arm for gripping by the pole climber to move the arms so that the fall arrest device can be raised or lowered, and each arm also has eyelets for receiving safety straps attached to the pole climber.  In a preferred embodiment the arms have sharp projections for biting into the pole.  A pull on the strap, due to slippage of the pole climber, causes the arms to move towards each other and the sharp projections to bite tightly into the pole.  Alternative embodiments are also described.

Abstract: Abstract of Disclosure The invention concerns a procedure for recovery of soluble carbo-hydrates present in wood, in connection with the alkaline cellulose digesting process. According to the invention, recovery of carbo-hydrates takes place at the initial phase of the cellulose digest-ing process, where the digesting solution contains dissolved poly-saccharides in abundance, while the content of polymeric lignin in the solution is low. A situation like this exists at the stage when the digesting solution has not yet reached the temperature at which the digestion process mainly takes place. As taught by the inven-tion, the carbohydrates are recovered by conducting digesting solu-tion to an ultrafilter, which separates the carbohydrates there-from, and by returning the filtered solution to the cellulose digestion. The carbohydrates that are obtained may be used e.g. in the manufacturing of sugar alcohols, or as raw materials for biotechnical processes.

Abstract: Abstract A series resonant converter is interposed between an unregulated voltage source and an output circuit.  The converter employs a pair of power switches each, when on, completing a series resonant circuit from the source to a resonant tank circuit including the primary winding of a transformer coupled to the output circuit.  The power switches are alternately turned on and off so that sinusoidal current pulses alternately flow in opposite directions in the primary winding at a frequency dependent on input and output conditions. The current flowing in the resonant circuit is monitored and the power switches are additionally controlled to prevent turn on of one switch and turn off of the other when current is still flowing in the resonant circuit.

Abstract: ABSTRACT OF THE DISCLOSURE    A disk brake actuator having a hydraulic slack-adjusting arrangement for maintaining a positive clearance between a brake shoe and a brake disk, includes a cylinder housing having disposed therein a brake-applying spring section, a hydraulic-operated release section, and an actuator piston spindle arrangement operably-connected to the spring section by means of a clutch arrangement.  A flange, formed on the actuator piston, acts as a plunger during a brake application and draws a first amount of hydraulic fluid into a first storage area, such first amount corresponding in volumn to the clearance between the brake disk and brake shoe when a nonworn brake shoe is first used.  Upon release of the brake, the actuator piston forces the hydraulic fluid back into a second storage area wherein is included a shuttle member movable with a shuttle chamber.  Additional hydraulic fluid is drawn from a reservoir when actuator piston movement, beyond the original clearance value, occurs as a result of brake shoe wear.  The additional hydraulic fluid corresponds in volumn to that amount of brake shoe wear and remains in the first storage area upon brake release, thus maintaining the actuator piston at the original clearance distance relative to the brake shoe and brake disk.          The additional volumn of hydraulic fluid is prevented from returning to the reservoir by a check valve.  A bleed screw in the reservoir allows bypassing the check valve when new brake shoes are installed and the additional hydraulic fluid must be returned.

Abstract: ABSTRACT:            "Method of and arrangement for restoring invalid samples of an equidistantly sampled signal"            Method of and arrangement for restoring samples, which are considered invalid, of an equidistantly sampled signal on the basis of correcting replacement valued derived from an environment of samples which are considered as being valid.           The values of the samples to be restored can be estimated in a simple and time-saving manner by determining, first of all, a quantity which represents a number of samples and is a measure of the periodicity of an environment of the valid samples, located at an interval containing invalid samples. Using a quantity thus determined it is possible to form a simple system of equations containing the values to be estimated as unknown quantities, it being possible to solve these unknown quantities on the basis of "real time" and using simple means. The proposed technique can advantageously be applied to the restoration of a speech signal in which intervals up to approximately 12 msec con-taining invalid samples may occur, It has been found that then unvoided speech can be restored in the same way as voiced speech.
