Abstract: ABSTRACT OF THE DISCLOSURE         A rock breaker of the type having a rotating impeller table mounted on a vertical axis for receiving rock which is flung at high velocity against breaker blocks mounted on the inner wall of an outer housing.  The impeller table is directly connected to the vertically mounted output shaft of a variable speed electric motor.  A single thrust bearing is mounted in a bearing housing positioned between the rotating table and the motor.  An inner housing encloses and supports both the motor and the thrust bearing.  The crushed rock falls between the inner housing and an outer housing.  Ventilation conduits provide cooling air to the motor and bearing and exhaust the hot air.  The ventilation conduits, in addition, serve as structural supports by connecting the inner and outer housing.

Abstract: ABSTRACT                    MELT DISPENSERS     A device for use in a hand held hot melt gun to prevent drool of melted composition from the outlet thereof when the gun is not in use is described and claimed.  In one embodiment of the invention the device comprises a melt body 10 having a melt chamber 12, resilient means provided by a coil spring 26 and means 36 for heating the melt body.          When in use a rod of composition urged by a feeding force in a direction towards the melt body 10 is melted in the melt chamber 12 and is dispensed in molten condition from the outlet 20.  When the feeding force is released after use the spring exerts sufficient force in a reverse direction to the direction of the feeding force to move the rod outwardly of the melt body, which relieves the pressure within the melt body  and thereby substantially prevents further composition from drooling from the outlet.

Abstract: ABSTRACT OF THE DISCLOSURE     Disclosed is a sector mark decoder for an optical recorder.  Sector marks are prerecorded on the optical recording surface and comprise a series of evenly spaced marks.  Data is recorded on the media in a fixed block code via holes burned into the optical recording surface.  Both sector marks and data are detected by common apparatus, but are distinguished from each other by their different recording format.  The location of a hole or a prerecorded mark is determined by comparing two sample and hold cells in a comparator.  One holds the read signal value received at one disk position and compares it to the signal value held in the other sample and hold cell received at the previous position.  If the comparison results in a new higher valued signal being found, the output of the comparator changes.  The new higher valued signal is retained and the other sample and hold cell samples at the next disk position.  This sequence continues until a sector mark has been decoded.  If the output of the comparator changes, the "address" of the change is recorded.  A sequencer determines from the "addresses" of a series of holes or prerecorded marks that a sector mark is being detected, and issues a sync pulse.  If the sequence of "addresses" does not correspond to a sector mark sequence, data holes are being read and a sync pulse is not issued.

Abstract: AN OPTICAL TRANSMISSION FILTER FOR FAR FIELD BEAM  CORRECTION           Abstract of The Disclosure The present invention deals with an optical transmission filter for effecting differential phase delay upon light in a beam polarized in a P dimension, as a function of position within the filter aperture for far field correction.  The filter employs two lenses of birefringent?material, the crystal optic exes of the respective lens materials being oriented in mutually orthogonal positions and at a 45° angle to the P dimension.  The lenses have their adjacent surfaces respectively concave and convex with the same radius of curvature and their non-adjacent surfaces flat.  The two lenses may be both spherical or both cylindrical.      The correction provides an improvement in beam quality in laser systems operating with larger beam apertures or at higher powers.

Abstract: ABSTRACT OF THE DISCLOSURE       POLYMERISATION OF OLEFINS USING A ZIEGLER-NATTA          CATALYST AND TWO ORGANOMETALLIC COMPOUNDS    The present invention relates to a process for the polymerisation of alpha-olefins in the gas phase in the presence of a Ziegler-Natta catalyst system consisting of a catalyst comprising atoms of halogen, magnesium and a transition metal, and cocatalysts based on an organometallic compound of a metal of Groups II or III of the Periodic Table of Elements, this catalyst supported on a granular substance. This process is characterised in that the polymerisation in the gas phase is carried out by contacting one or more alpha-olefins, on the one hand with the prepolymer or the supported catalyst system comprising an organometallic compound (a) which is only slightly volatile as cocatalyst, and on the other hand another cocatalyst consisting of an organometallic compound (b) which is relatively volatile, in such a way that the total quantity of cocatalyst employed is relatively small.

Abstract: SEAT BELT FASTENER               ABSTRACT OF THE DISCLOSURE A latch mechanism is designed to secure a safety belt to the upper surface of a seat at any of a plurality of positions spaced longitudinally along the seat surface.  The mechanism includes a loop extending downward from the end of the safety belt to fit into any of a series of slots arranged in a longitudinal row along the seat surface.  Below the seat surface is a longitudinal channel retaining a plunger.  A longitu-dinal row of hooks, each capable of engaging the seat belt loop, extends upward from the plunger, having the same number and spacing as the slots.  The plunger is capable of sliding longitudinally inside the channel, but is biased to a position in which the hooks are aligned with the slots.  Retraction of the hooks and hence release of the seat belt loop is achieved by manual mani-pulation of the plunger.  Proper selection of a slot for insertion of the seat belt loop will comfortably yet securely retain an infant or toddler within a range of body sizes.

Abstract: CUFF AND STRAP DEVICE FOR LIFTING WEIGHTS            ABSTRACT     This invention relates to wrist-support apparatus and to weightlifting accessories, and in particular discloses a cuff and lifting strap device for a weightlifter's wrist and hand.          The lifting strap extends from a padded wrist cuff down around the weight bar to be lifted. The lifting strap terminates in fold around a rubber plug that tucks behind the bar in the palm of the hand. When the user grasps the strap and the bar to lift it, the plug is wedged above the bar and prevents the strap from slipping off the bar. The device is useful in preventing tissue injury to the hand and to the wrist. The device is safe in that the plug at the end of the lifting strap to the cuff allows the strap to be immediately released upon the hand being opened and the weight bar dropped in the event of an unmanageable weight being lifted.
