Abstract: An ohmic heater comprises at least two electrodes 1 contained within a vessel 2 such that the electrodes lie along the length of the vessel 2. The vessel 2 has inlet and outlet ports 4 and 12 in the top and bottom through which a fluid to be heated flows, passing through the vessel 2 along the length of the vessel 2. The electrodes 1 are equally spaced about the axis of the vessel 2 and when in use, are connected to a power supply, such that the total voltage at any point in time at the electrodes is near or at zero. Hence, when in use, a current passes perpendicular to the flow of the fluid, but the electric potential on the axis is near to zero, and hence the leakage current from the ohmic heater is substantially reduced.

Abstract: Data circuit terminating equipment DCE (100) which allows the connection of a Data terminal equipment DTE (63) to a telecommunication line and which includes timing arrangements circuits for particularly providing the DTE with transmitter signal element timing (114) and receiver signal element timing (115). The DCE includes processing means (61) for computing a sequence of digital values A(n) and means (60, 23, 22) for deriving from said sequence of digital values A(n) a corresponding sequence of interrupt signals T(n). The DCE further includes timing arrangement circuits (69, 70, 71) for generating a set of N timing pulses at the nominal rate on the occurrence of one interrupt signal T(n). By controlling the generation of the sequence of digital values, the processing means (61) can control the frequency, the phase of every clock generated by the timing arrangements circuits. The receiver signal element timing, the transmitter signal element timing the transmit sampling clock pulsing the D/A converter and the receive sampling clock pulsing the A/D converter are controlled by different sequence of digital values computed by the processing means. By generating appropriate sequences of digital values, the processing means can provide any relationship between the different clocks: a transmit signal element timing being slaved on the receiver signal element timing in a synchronous mode, on an external clock in a tailing mode. The timing arrangement circuits can also provide a transmit sampling clock slaved on the receive sampling clock in order to perform powerful digital echo cancellation techniques. More generally, the processing means (61) can provide any relationship between two determined clocks. Moreover, the DCE including a DTE receive interface circuit 21 transmitting a set of N receive data at the nominal receive clock rate and maintaining the N data bit until the next interrupt signal, the processing means can control the length of the Nth bit, which when a STOP bit can allow the compensation of the DTE and the line data throughput difference.

Title: Cardiac assist pump.
Inventor: DORMAN FRANK
IPC: A61M60/871
Filed: 1990-06-18
Abstract: A centrifugal pump for left ventricle assist includes a pump housing forming an impeller chamber with inlet and outlet passages and enclosing an impeller rotatable to move blood through the impeller chamber, and a rotor chamber enclosing a rotor integral with the impeller and rotatable to drive the impeller. An elastically deformable seal member separates the rotor and impeller chambers, and includes an annular lip seal surrounding a shaft which joins the impeller and rotor. A saline solution is supplied at a constant fluid flow rate to the rotor chamber through an inlet passage, and leaves the rotor chamber by perfusing into the impeller chamber along the interface between the shaft and lip seal. The saline solution thus provides hydrodynamic bearings between the rotating shaft and rotor, and the fixed pump housing and lip seal, and further prevents blood in the impeller chamber from entering the rotor chamber. The lip seal is configured to encourage flow of saline solution along the lip seal/impeller shaft interface, while resisting the flow of blood along the interface.

Abstract: A planar thin film magnetic head is disclosed wherein an axis of easy magnetization in the vicinity of a magnetic gap (g) of a magnetic yoke (37)is forcibly made coincident with the direction of a track width by a magnetic field due to current flowing in a conductor layer (38). Accordingly, even though the track width is small, a high magnetic permeability, low Barkhausen noise and linear responsiveness can be realized to thereby improve the sensitivity, output and linearity. In another aspect of the invention, a throat portion is eliminated from a thin film magnetic core forming a magnetic gap. The thin film magnetic core is configured such that a pair of magnetic members constituting the magnetic core are diverged from the magnetic gap so that a divergent angle ϑ, of first opposite side edges of the magnetic members, from a direction of the gap length of the magnetic gap, is set to the range of 30° ≦ ϑ ≦ 80°, and the magnetic members have second opposite side edges extending in substantially parallel to the direction of the gap length of the magnetic gap. Accordingly, even though a track width is reduced less than 10µm, adjoining crosstalk or off track crosstalk can be avoided to thereby realize low-noise and high quality reproduction and improve the operating characteristics.

Abstract: For a wide variety of reasons, it would be desirable to affix identification labels, such as serial numbers, to tires. Such labels should be capable of lasting the entire life of the tire which may include being retreaded on multiple occasions. From a commercial standpoint, it is also very important for the label and the means of affixing it to the tire to be inexpensive. This invention discloses such a technique for affixing identification labels to tires. This information specifically relates to a method of preparing a pneumatic rubber tire having an outer circumferential tread, a supporting carcass therefor, two-spaced beads, two rubber sidewalls connecting said beads, and a rubber innerliner having an identification label affixed thereto, said process comprising (a) applying the identification label to the rubber innerliner of an uncured tire, wherein the identification label is comprised of about 35 to about 90 weight percent syndiotactic 1,2-polybutadiene having a melting point which is within the range of about 70°C to about 160°C and about 10 to about 65 weight percent of at least one polydiene rubber which is cocurable with said syndiotactic 1,2-polybutadiene, sulfur, zinc oxide and at least one pigment or colorant; and (b) curing the tire. Labels containing virtually any type of information can be affixed utilizing this technical. For instance, the identification labels can include conventional numbers and/or letters, computer readable dot matrix identification, or a bar code.

Abstract: A collision sensor specially adapted for a power driven x-ray imaging apparatus includes a face collision sensor (30) and an edge collision sensor (32). The face collision sensor has two annular plates (34, 35) which are biased apart longitudinally by three flat springs (50) which are equiangularly spaced apart around the perimeter of the plates. Three equiangularly spaced cables (70) hold the plates in parallel planes with the springs prestressed and collapse to allow the plates to be compressed together. Two sets of three switches each reside at equal angular intervals between the plates, with at least one of the switches of the first set being actuated when any point across the face of the sensor has been moved a predetermined longitudinal distance. At least one of the switches of the second set is actuated when the point on the face of the sensor has been moved a further predetermined longitudinal distance. The edge collision sensor includes a closed air bladder (38) which surrounds the face collision sensor and in which a vacuum is drawn. A collision occurring around the edge of the face collision sensor causes an increase in the pressure of the bladder. A first pressure sensor is actuated if the pressure increase exceeds a first predetermined amount. A second pressure sensor is actuated if an additional predetermined increase in pressure occurs.

The stops (53 a , 53 b ) can be formed by two spaced apart protrusions that also permit deformation of the slide element as the click-stop protrusion (51) travels past the protrusion (32) in the through-hole (31).
