Abstract: ABSTRACT OF THE DISCLOSURE            Allocation of space of peripheral storage devices to host processes is based upon free or unallocated space in each such device.  The device, irrespective of capacity, having the largest free space is most likely to receive a next space allocation.  A central record in a multi-host system stores free space indications.  In a disk storage device free  space is indicated by the number of unallocated data storage record tracks for each such device.

Abstract: ABSTRACT      A microinstruction control storage mechanism includes a read-only store (ROS), writeable control store (WCS), first cycle control store, and a reserved portion of main storage in a data processing system. As required, blocks of microinstructions are paged into the WCS from the main storage.  An array of single-bit storage devices, accessed by microinstruction addresses utilized to access microinstructions from the ROS, signal the existence of a faulty microinstruction from the ROS as determined by maintenance or design personnel.  In response to a halt signal from an accessed single-bit storage device, an address substi-tution mechanism creates a microinstruction address which identifies a main storage location and may have to be used to initiate transfer of a block of micro-instructions from main storage to the WCS to provide access to a particular substitute microinstruction for the faulty microinstruction.

Abstract: ABSTRACT OF THE DISCLOSURE The invention pertains to an apparatus for extracting a cork from a bottle comprising a cork-engaging member, including a corkscrew, and a holder for aligning and guiding the corkscrew, via its own diameter, with respect to the bottle.  The cork-engaging member is completely removable from the holder for independent use, and to permit the corkscrew point to be used to sever the metal foil, which covers the bottle top, and both the holder and cork engaging member to be more easily cleaned.  The holder includes a plural-ity of longitudinally extending circumferentially spaced, radially deflectable gripping elements connected to and spaced downwardly from a guide which receives the corkscrew, and are all approximately equally resiliently biased to a normal unflexed radial position.  The corkscrew itself is improved by the provision of an outer layer of friction reducing material such as a tetra-fluoroethylene or other suitable  plastic.  Additionally, the tip portion of the corkscrew is formed in an improved manner which prevents fragments of cork from breaking off and falling into the bottle even though the screw is driven completely through the cork.  Also disclosed is an improved method of making such a corkscrew.

Abstract: Abstract Tablet Dispenser A dispenser for dispensing tablets one at a time has a reservoir, a chamber below the reservoir in which the tablets are arranged in a single layer and a dispensing passageway which leads to a dispensing orifice.  The passageway is of such a width that a single column of tablets can be accommodated.  The passageway is defined by portions of a moving slider member and can be moved from a non-dispensing position to a dispensing position.  In this latter position the lowermost tablet is dispensed whereas the remaining tablets in the column are retained in the passageway by a fixed protuberance.  One side of the passageway is resilient to minimise tablet damage. The slider member is adapted to assist the passage of tablets from the reservoir to the chamber.

ABSTRACT OF DISCLOSURE            Arrangement in a fuse for projectiles with explosive charge for changing over between direct and delayed ignition of the explosive charge. The arrangement comprises a movable contact member which in an initial position short-circuits an electrical igniter which is designed for direct ignition of the explosive charge. A locking member in the form of a pin in an initial orientation of the projectile takes up a position in which the contact member can move under the influence of the accelerational forces effective on the projectile to a second position where the contact member is held by a detent device. With a second orientation of the projectile the pin, as a result of its own weight, drops down to a position where it prevents the contact member moving from the said initial position.

Abstract: MAGNETIC COUPLING ASSEMBLY FOR ACCUMULATING POWER ROLL CONVEYOR                         ABSTRACT OF THE DISCLOSURE     A magnetic coupling assembly for driving a conveyor roll from a power drive while automatically disengaging the conveyor roll from the power drive when an accumulation occurs of the parts being transported by the conveyor. In one embodiment, a drive sprocket and conveyor roll are mounted on a fixed axle between a pair of spaced conveyor side rails. The conveyor roll includes a tube portion having a permanent magnet mounted therein and the drive sprocket includes a sprocket hub having a field face member secured to one of its ends in opposing relationship to the permanent magnet. By varying the air gap between the permanent magnet and field face member, the torque capacity is varied, thereby permitting slippage between the drive sprocket and conveyor roll at different torque levels. The sprocket hub is slidable on a bearing cartridge assembly and the field face member is slidable on a thrust tube in response to operation of an adjustment member for varying the air gap between the permanent magnet and field face member. Long service life is possible with minimum maintenance because of the total bearing construction. In another form of the invention, the drive sprocket is mounted outboard of the conveyor side rails. In this embodiment, the drive sprocket and conveyor roll are mounted on a rotatable axle with the basic components for the magnetic coupling assembly being the same as for the first embodiment.

The gas then passes through slots in the outer casing of the internal cyclone assembly and spirals downwardly at an increased velocity thereby de-positing any remaining liquid from the gas stream which then exits upwardly through a central outlet of the inner cyclone assembly.  The liquid from both separating stages flows down the casing to the base thereof and an automatic level con-trol, controls a vessel drain valve.

Abstract: Abstract of Disclosure The invention concerns a procedure and means for comminuting stumps. At present, the stumps have to be transported mainly as whole stumps to factory plants, whereat the stumps contain earth and stones up to 50%. In the further treatment problems are caused by the separation of earth and stones from the stumps.            The object is to provide a procedure and means for comminuting stumps which is suitable to be used at forest working sites mounted on a mobile chassis, for instance on a forest tractor. As taught by the invention, the stumps are fed into a substantially vertical, essentially stationary feed drum (1) upon a bottom (4) rotating about a vertical axis (3) so that the stumps tend to the outer periphery (5) of the drum under centrifugal force action and re-volve along with the bottom, bracing themselves against a counter-member (6) which is fixed with reference to the bottom, and are cut into pieces as they hit against a blade (7) which is fixed with reference to the drum. The comminuted stumps are removed from the feed drum through a tangentially outwardly opening discharge aper-ture (8). The comminuted stumps are preferably conducted from the feed drum to a cleaning drum (10), from there to a sieve (11), the acceptable fraction to a product storage, and the reject to be comminuted again.
