Abstract: PERIPHERAL INTERFACE ADAPTER CIRCUIT FOR USE IN I/O CONTROLLER CARD HAVING MULTIPLE                 MODES OF OPERATION     Abstract This adapter contains two separately controll-able sections, each transferring data in various formats between a peripheral device interface and either a microprocessor contained in an associated I/O controller or a host processor or both. Dedicated controls enable the adapter to operate autonomously after being prepared by the micropro-cessor.  Separate but interconnectable handshaking controls enable the sections to operate either asynchronously or in time coordination with each other.  Handshaking controls in plural adapters are interconnectable to coordinate related transfers of data between a device and one or more hosts via plural adapter paths.  Programmable commands enable the microprocessor to condition the adapter to conduct various data transfers autonomously. Such data can be transferred to or from the device interface in various bit-parallel formats defined by the commands, and from or to the host processor, the microprocessor, or both the host processor and microprocessor concurrently.  In one handshaking mode, the adapter sustains an array indexing operation in which one section transfers "address" data to a device and the other section transfers "addressed" portions of a data array between the same device and either the host processor or the microprocessor.

Abstract: ABSTRACT OF THE DISCLOSURE           A surgical case cart having a closed container supported on a chassis.  The closed container includes a pair of front door panels hinged to side door panels which in turn are hinged to side wall sections, so that the container can be completely opened with the front and portions of the sides being exposed by the door panels wrap-ping around the side and back.  The door panels are formed of single pan construction so as to avoid cracks and crevices, and yet exhibit rigidity of a double pan door construction. The lower edges of the door panels provide A baffle effect to reduce the movement of contaminated air into the cart.  The top of the cart contains an overhang lip to prevent liquids from spilling into the container.  Stem mounted casters are utilized to avoid flat horizontal surfaces on which dirt can collect.  The intersection between the back, sides and chassis Is constructed to avoid the possibility of collecting contami-nation and bacteria.  A door latch is provided which indicates whether the contents of the cart are sterile or contaminated. Opening of the cart door panels nevertheless can be accomplished without the use of the operator's hands,  The cart construction therefore provides improved sterility, greater accessibility, and brings about easier maintenance

Abstract: ABSTRACT: "Voltage translator."     A bipolar voltage translator contains a pair of differentially-coupled transistors for converting an input voltage supplied to the base of a first (Q1) of the pair into an output voltage taken between a first resistor (R9) and the collector of the second (Q2) of the pair. A second resistor (R12) is coupled between a VEE supply and a current-source transistor (Q4) which supplies current to the differential pair. The current-source transistor is controlled by a reference voltage which equals VEE + (1 + ?) VBE where ? is in the range 0.2 to 3Ø The ratio of the first resistor to the second resistor is desirably .beta./? where .beta. VBE is the output voltage swing. Circuitry such as a Schottky diode (S4) is coupled between the emitters of the differential Pair to prevent the emitter-base junction of the second transistor from break-ing down. Where the transistors are NPN devices and .beta. equals 1, the output voltage is provided at levels suitable for current tree logic.

Abstract: ABSTRACT OF THE DISCLOSURE          Movable (a head) and stationary (a stator) members are disposed in contiguous relationship.  First magnetizable and non-magnetizable zones are alternately disposed on the stator in a particular direction.  Second magnetizable and non-magnetizable zones are alternately disposed on the head in the particular direction.  The zones on the head and the stator face each other and have substantially equal spacings. First components are associated with the head for producing magnetic fluxes in the magnetizable zones in the head and stator in a particular pattern to obtain incremental relative movements between the head and the stator on a vectorial basis in the particular direction.  Second components are associated with the head for compensating for hysteresis effects in the magnetizable zones in the head and stator.  The second compo-nents may produce magnetic flux of alternating polarity and decaying amplitude near the end of each incremental movement of the head relative to the stator.  Components are provided for indicating the position of the head relative to the stator in the particular direction at each instant. Components are included for obtaining the production by the first means of magnetic fluxes at each position to provide corrections in the incremental movement of the head relative to the stator in the particular direction at that position.

Abstract: _ 30 -DUPLEX SIGNALING CIRCUIT            Abstract A duplex signaling circuit for signaling with respect to a line circuit includes a resistance bridge hybrid having a modified resistance makeup to reduce power consumption and improve longitudinal current immunity without altering conjugacy between signaling transmission and receiving connections to the bridge.  An electronic relay emulator, which is responsive to bridge hybrid output signals representing received line circuit signals, provides relative immunity to noise and to pulse splitting for thereby relieving a hybrid balancing impedance capacitance of those functions so that a compromise capacitor value can be selected for balancing a relatively wide range of signaling line circuits.  A user-stepped, successive approximation, adjustment process for the balancing impedance is implemented in the signaling circuit.

Abstract: CRYOSTAT FOR NMR MAGNET                Abstract of the Disclosure A cryostat which is particularly useful for containing superconducting windings for a magnet to provide high strength magnetic fields for NMR imaging comprises a set of nested annular vessels in a suspen-sion system which permits transport of the cryostat and magnet assembly with vacuum conditions intact.  In particular, sets of transverse ties linking certain vessels to the next adjacent outer vessel are employed to prevent transverse motion of the cryostat assembly. Furthermore, during transport, a system of pins is employed to prevent axial motion, while at the same time minimizing thermal conductivity.  During transport, the inner annular assemblies are locked in a fixed axial position which permits transport of the cryostat in a vertical position.  A system of the present invention is therefore seen to satisfy the competing requirements for a strong internal support system for transport, but yet at the same time provides a suspension system which does not significantly impair the thermal insulation re-quirements of good cryostat design.
