Abstract: AN IMPROVED TOOTH DESIGN TO AVOID SHEARING STRESSES            Abstract of the Invention Teeth disposed on the bit face of a rotating bit are, angularly oriented on the sloping surface of the bit face such that a vertical loading force which is applied to each tooth vectorially sums with a wedging force exerted by the rock formation on each tooth to create a resultant force applied to the diamond cutting element included within the tooth. The angular orientation of the tooth is chosen such that the resultant force is applied to the diamond cutting element in a direction which minimizes shear stress on the element.  For example, in the case where the diamond cutting element is an equilateral triangular prismatic element tangentially set on the bit face with one apical edge defined by two adjacent triangular sides outermost on the tooth, the orientation or inclination of the tooth with respect to the vertical loading force and wedge force is such that the resulting force lies near or on the bisector of the dihedral angle formed by the apical edge.          Similarly, the diamond cutting element is rearwardly raked in the longitudinal direction, generally parallel to the tangential motion during normal drilling as defined by the rotation of the bit, such that the vectorial sum of the vertical loading force in a reactive cutting force applies a resultant force on the diamond cutting element in a direction which minimizes shear stress, namely, in the example in a direction approximately perpendicular page 1 to one of the end faces of the triangular prismatic diamond cutting element.     page 2

Abstract: ABSTRACT         This invention relates to a cardboard container made from a one piece blank for packing subcontainers and designed for shipping in shipping containers that have inwardly extending ribs.       The cardboard container is comprised of contour side walls adapted to wrap around a group of sub-containers and provide an open top opening and dividers extending between opposed sidewalls to divide the container into compartments of a size to hold one subcontainer.          The transverse dimension of each divider is less than the combined width of the subcontainers on each side of it whereby, at the location of the dividers, there is an indentation in the sidewall that will accommodate a rib structure in a shipping container.  At least one of said dividers has a handle formation associated therewith.

Abstract: ABSTRACT                      STORAGE MEDIUM CONTROLLER        A dual mode disk controller is disclosed for use between a host processor 14 and its storage medium for controlling data transfer to and from the storage medium.  The data is formatted on the medium in two distinct formats, one capable of bulk fast transfers useful in a swapping operation, and the other capable of periodic slower transfers as is acceptable for file retrieval.  The disk controller is designed having a small fast buffer memory 106 for accepting information from the storage medium.  File transfer data it transferred immediately without host CPU intervention, to a larger cache memory 107.  The host CPU 14 accesses the fast buffer memory 106 periodically to retrieve swap transfer data while only accessing the larger cache memory when it needs to retrieve the file formatted information.

Abstract: ABSTRACT OF THE DISCLOSURE:          Optical fibre cables are produced containing an extruded support member of thermotropic liquid crystalline polymer in which the extrusion conditions are used to control the thermal expansion coefficient of the support member.  The support member may be extruded on to the support member. In this case extrusion conditions may be used to induce a compressive strain on the fibre which can counteract the thermal change in length of the fibre when subject to temperature variations so that a cable having an optical path length which is less sensitive to temperature variation can be produced.  Support members which provide a loose fitting sleeve over the fibre can be produced by control of extrusion conditions to have a thermal expansion coefficient of not less than -5x10-6/°K.

Abstract: ABSTRACT OF THE DISCLOSURE    A brake control arrangement for use with a multiple disk brake system having a plurality of disk brake actuators which exert a braking force in relation to the fluid pressure presented to a service braking portion contained therein.          A handle valve is operable over a range of travel for delivering a braking fluid pressure to be directed to a first input of one of a plurality of shuttle valves.  This braking fluid pressure, however, is first directed through one of a plurality of flow paths selected by a selector valve arrangement.  The selector valve arrangement can be sequenced to direct the initial braking fluid pressure through a different one of the plurality of flow paths upon receiving a sequencing count signal transmitted from a counter valve arrangement.  A pilot operated relay valve has a pilot portion which receives the braking fluid pressure and opens the relay valve when the braking fluid pressure reaches a predetermined value.  The fluid pressure transmitted through the relay valve is proportional to the braking fluid pressure and is directed to a second input of the plurality of shuttle valves.  The shuttle valve outputs are connected to the service braking portions of the disk brake actuators and serve to transmit the higher of the two input fluid pressures to these service braking portions.  The counter valve arrangement trans-mits the sequencing count signal when the parking brake por-tions of the disk brake actuators have been released.

Abstract: Abstract of the Disclosure:         In a pager receiver operable in response to a call signal comprising a first part including a call number signal, a second part including a message signal, and an intermediate part placed between the first and second parts, the intermediate part conveys a time interval signal representative of a length of a message carried by the message signal. When the call number signal is destined to the pager receiver, a receiving circuit is put into an operating mode during the length of the message.  Otherwise, the receiving circuit is kept in a nonoperating mode during the length of the message.          The time interval signal is therefore detected even when the call number signal is not destined to the pager receiver.  The intermediate part may comprise a message control signal defining message control operations of the pager receiver and a time signal for specifying a transmission time instant of the message signal.          A wide variety of the message control operations can be designated by the message control signal.

Abstract: PROCESS FOR PRODUCING DEGUMMED VEGETABLE OILS AND GUMS OF HIGH PHOSPHATIDIC ACID CONTENT            ABSTRACT OF THE INVENTION    A process for producing at the same time degummed vegetable oils and gums of high phosphatidic acid content is described. The starting materials for this process are vegetable oils which have been conventionally water degummed and accordingly still contain too much non-hy-dratable phosphatides and iron for further processing by physical refining and providing a refined oil of good keepability. Therefore in a first stage of the disclosed process a non-toxic aqueous acid, e.g. phosphoric acid, is finely dispersed in the water degummed oil and suffi-cient contact time is allowed to complete the decomposition of the metal salts of phosphatidic acid. In a second stage a base is added to increase the pH above 2.5 without sub-stantial formation of soap and in a third stage the aqueous phase containing the gums and the oil phase are separated. Surprisingly this process not only results in a degummed oil with very low phosphorus and iron contents which make the oil suitable for physical refining but also provides gums of high phosphatidic acid content with improved usability.
