Abstract: ABSTRACT    The present invention relates to salts with basic amino sugars or basis amino acids of certain   carboxy or 2-tetra-solo-chromones.  These compounds exhibit pharmacological properties in that they are antagonists of the slow-reacting substance of anaphylaxis (SRS-A) or its pathological effects. The compounds are thus useful in the treatment of disorders in which SRS-A is a factor, for example skin afflictions, hayfever, and obstructive diseases of the airways, such as asthma.  Amino cold and amino sugar salts of the present invention are more soluble than the corresponding alkali-metal salts, thereby permitting the administration of higher concentrations of active ingredients to the patient.  Moreover, the salts of the present invention overcome the problem of cloudiness which develops when corresponding alkali-metal salts are left to stand for some time.

Abstract: INDUCTION MOTOR CONTROL SYSTEM                 ABSTRACT OF THE DISCLOSURE       A variable frequency power supply device supplies an AC power to a squirrel-cage motor through an AC parameter control.  The control receives a command active current resulting from a command torque and a command exciting current to generate a resultant current and its phase.  The command torque is produced from the actual and command motor speeds and the exciting current is caused from the actual motor speed.  The control also receives a command frequency determined by the actual motor frequency and  a command slip frequency also resulting from the command torque.  The control controls the firing phases of thyristors in the power supply device in response to the command current, phase and frequency.  The control may generate a voltage for supplying the active current and an exciting voltage to similarly control the firing phases of the thyristors. In the latter case, the exciting voltage may be added with its differential to compensate for a rapid change in active current.

Abstract: ABSTRACT OF THE DISCLOSURE      This invention relates generally to improved elec-trical connectors for mounting integrated circuit devices to circuit boards and the like and, more particularly to elec-trical connectors having improved covers for pressing the substrates on which the integrated circuit devices are mounted against electrical contacts of the connectors to insure good electrical connection.  In prior connectors, the integrated circuit device is initially positioned in an in-sulator base and then secured therein by a rigid insulator cover.  The base includes a plurality of individual metal contacts, one for each conductor pad on the integrated cir-cuit device substrate.  The force with which each of the electrical contacts presses against the corresponding con-ductive pad on the integrated circuit device substrate may vary widely in some connectors due to manufacturing toler-ances of the contacts as well as variations in the thickness of the substrate within specified tolerance.  This, in turn, may result in less than satisfactory electrical connection between one or more contacts and the corresponding pads. According to the present invention a resilient cover applies pressure at several points on a s?strate on which the in-tegrated circuit device is mounted ?o press the substrate against support surfaces in the connector base.

Abstract: ABSTRACT OF THE DISCLOSURE:    An infeed disc for a disc refiner has infeed passages which are circularly spaced by portions thereof which define spokes.  The spokes and the passages have special characteristics.  The center line of each passage is skewed with reference to the axial center line of the disc, in both an axial and a circular sense, and thereby curved, causing the passage to be essentially curved to provide a circular offset of the openings from the respective ends of each passage.  The disc is further characterized by non-radial skewed orientation of its spokes, the center line of each spoke being angularly inclined to a plane which is radial to and includes the central axis of the disc.  The centers of the respective axially spaced infeed and operating surface portions of the spokes are offset one from the other, in a circular sense.  The leading and trailing edges of each infeed passage at the operating face of the disc are also each respectively offset from the corresponding leading and trailing edges at the infeed face of the disc, in a circular sense, about the central axis of the disc.  One wall surface of each spoke provides the leading wall portion of one of the passages, having regard to the direction of rotation of the disc in use, and is distinguished by a longitudinally extended offset at the entrance end of the passage of which it forms a part.  This offset is in the direction of disc rotation and creates an insuction effect as the disc rotates.

Abstract: ABSTRACT OF THE DISCLOSURE         There is provided a single lever joystick having movement in X and Y directions and rotation about a further axis Z wherein axes X, Y and Z are substantially perpendicular.  The joystick can be moved in all three senses at the same time.  Movement of the joystick is resiliently restrained to a selected neutral position.  Resiliency is obtained from substantially plate-like springy members to which are attached strain gauges.  Each of the strain gauges is capable of producing a continuously variable electrical resistance output which is a function of the displace-ment of the joystick from its neutral position.

Abstract: CONCEALABLE WALLBOARD FASTENER            ABSTRACT OF THE DISCLOSURE:         A fastener for use with other such fasteners in concealably holding wallboard panels to framing members and in abutting linear relationship with each other is made of sheet metal and includes a first part suitable for fastening to and against a framing member, a second part overlying a part of said first part and farther from the framing member than the first part, when installed, an intermediate section connecting said first and second parts so they can move relatively, with the intermediate section resisting such movement, a web extending from said second part and at the web end,an impaling part for insertion into a wallboard.  The first and second parts of the fastener are substantially flat and in parallel planes and spaced from each other, with the result that the intermediate portion serves in the capacity of a movement-resisting hinge or spring, absorbing energy which may be applied to the wallboard, as by mechanical shocks, diminishing vibrational effects and improving acoustical properties of the wallboard assembly. Preferably the impaling part  is  a pair of pointed members substantially parallel to the first and second fastener parts.  The fasteners are installed (impaled) alternately on abutting portions of first and second wallboards, with the first parts of such fasteners impaled on the first wallboard being held to a framing member and with the fasteners impaled on the second abutting wallboard having first parts thereof fitted behind the first wallboard to hold the wallboards in aligned linear relationship.  Also described are fasteners of modified designs and including additional features, such as mounting slots, mounting adhesive means, "leading" edges for facilitating assembly and for spacing the wallboard from the framing member on which it is mounted, supplementary "spring" members, intermediate sections of modified structures, installed fasteners held in place substantially flat against the wallboard and bendable into desired shape, and divisible or convertible fasteners, a portion of which, after such division, may be used to hold a wallboard at right angles to another such board.
