Title: Membrane oxygenator
Inventor: DIETTRICH LAMBERT JOHN JR
IPC: A61M1/14
Filed: 1984-03-08
Abstract: A novel device for mass transfer across a membrane is disclosed, which is particularly suitable for use as a blood oxygenator. The novel device is of the type having a pleated, selectively permeable membrane defining first and second sets of alternating pockets for the flow of a fluid to be treated (e.g. blood) and a treating fluid (e.g. oxygen), and a discrete support screen disposed within each of the pockets of said first and second sets. Of considerable importance is the feature that the support screens are designed to be substantially interdigitated when the assembly of membrane and support screens is held as a compressed stack within the housing of the device. The novel mass transfer apparatus may be utilized as a compact blood oxygenator with excellent gas transfer rates, low pressure drops and negligible trauma to blood components.

The logic status signal indicates an open load when the switch is open and a short-circuited load when the switch is closed. In the case of an open, short-circuited switch (1), the status signal suggests an open load. One information line (18) is connected like the load lines (17) via one of the electronic switches (1) to the supply voltage and leads out of the central unit (15). The information line (18) is in each case connected via an information switch (19) to at least one load line (17). <IMAGE>

Title: Output multiplication method and apparatus
IPC: F02B75/02
Filed: 1980-09-12
Granted: 1985-07-17
Abstract: An output multiplication apparatus comprises a solenoid motor in which a stator 1 has protruding poles 11, 12 teeth 11a 12a and single phase magnetizing coils L; a rotor 2 has a pair of axially spaced pole members 22, 23 with teeth 22a, 23a; a d.c. exciting coil L<1> is wound around the rotor axis between the two members 22, 23; a capacitor C is connected in series or parallel with the stator exciting coil to form a resonant circuit; an a.c. power source is connectible to the stator coils L; and a d.c. current source is connectible to the rotor exciting coil L<1>. The capacitive reactance is equal to the inductive reactance presented by the stator exciting coil of the solenoid motor in response to the line frequency so that the total impedance will be Z tau  =  2ROOT R<2> + (XL-XC)<2> = 2ROOT R<2> = R, where R is the sum of the resistance of the capacitor and the d.c. effective resistance in the stator exciting coil of the solenoid motor, Therefore, an increase in the frequency of the power source for the solenoid motor will not result in the proportionate increase in the line voltage, and the output is such that it will have a constant torque under variable operation speed. Accordingly, under the same power input, the output horsepower is proportional to the line frequency. <IMAGE>

Title: Method of and apparatus for converting an analogue voltage to a digital representation
IPC: H03M1/12
Filed: 1981-08-17
Granted: 1984-07-11
Abstract: An analogue voltage-to-digital converter has a voltage divider (11) with a plurality of steps (13) for comparison with the unknown voltage and in addition provides interpolation between steps to improve the accuracy. Interpolation is effected by adding a ramp voltage from a generator (22) to the unknown, the ramp voltage ramping through a magnitude equivalent to at least one step. With one tap (13) on the voltage divider (11) selected, comparison of the unknown plus ramp voltage is effected in a comparator (14) successively as the voltage ramps. By noting when the combined voltage reaches the level of one of the reference voltages and by counting in a microprocessor (16) the number of comparisons made from the time when the ramp voltage is at a predetermined magnitude and comparing this with the time taken to ramp through one or a plurality of whole steps, determination can be made of the magnitude of the unknown voltage to a fraction of a step.

Title: Television display system with reduced line-scan artifacts
Inventor: POWERS KERNS HARRINGTON
IPC: H04N5/44
Filed: 1982-08-31
Granted: 1986-06-11
Abstract: A flat-field television image having reduced visibility of horizontal scan lines is generated by receiving first and second fields of interlaced video and progressively generating a scanned image within a time for one incoming field. The progressively scanned image contains interstitital lines between the lines of one field, and consequently the line-scan structure is made less visible, but the flicker rate is undesirably decreased. In order to increase the flicker rate, additional progressively scanned images are generated at a rate equal to or greater than the incoming field rate.
