Title: Apparatus in spark generators
IPC: F23Q3/00
Filed: 1985-07-01
Abstract: Ignition apparatus, e.g. for oil burners, comprising an oscillator circuit (20) to which is connected a transformer with a primary (7,8) and a secondary circuit (12), the secondary circuit being connected to spark electrodes (13,14). The oscillator circuit is, for example, connected to an AC mains (1,2) via a rectifier (5) so that when a rectified half-wave occurs there is operating voltage for the oscillator (20) which starts high-frequency spark generation. The transformer is implemented such that close coupling exists between a primary winding part (7) and the secondary winding (12) and that there is also close coupling between a second primary winding path (8) and a winding (16) controlling an oscillation energy circuit. The second primary winding path (8) and the feed-back winding (16) are geometrically arranged laterally on the transformer core (9) in relation to the primary winding.

Title: Measurement circuit for evaluating a digital-to-analog converter
IPC: G01R31/28
Filed: 1986-02-13
Abstract: The measurement circuit for evaluating a digital-to-analog converter (DAC) comprises a clock generator (11) for generating clock pulses, a word generator (3) for generating digital input word for the DAC (1) under clock control, a sampling unit (5, 13, 15) for performing a delayed sampling of the analog DAC output signal under clock control, with a fixed delay time, and a pulse swallower (17) and the word generator (3) for selectably swallowing a number of clock pulses, thus to introduce a permanent time shift between the application of digital input words to the DAC (1) and the sampling of the analog DAC output signal. Thus a digital input word may be selected, by selection of the number of pulses to be swallowed, for application to the DAC (1) for subsequent sampling of the corresponding DAC output signal to occur. This eliminates the need for using a programmable delay line in the sampling unit. The sampling unit (5, 13, 15) may include a fixed delay line (15) and a frequency divider (13). The sampled analog output signal may be digitized by an ADC (7) and processed by a microprocessor (9, 19)

Title: Method of determining endothelial cell coverage of a prosthetic surface
IPC: G01N1/30
Filed: 1987-11-06
Abstract: Determination of the effectiveness of endothelial cell seeding upon a vascular graft surface within the operating room environment would be desirable to maintain quality control in any clinical trial. In this study, five fluorescent stains, mithramycin, Hoechst 33342, sulfofluorescein diacetate, Nile red, and rhodamine 123 were evaluated for their ability to fluorescently label endothelial cells on graft material and subsequently allow determination of seeded cell number and cell spreading. Of these agents, rhodamine 123 produced the most desirable characteristics. It allowed excellent cell visualization after a 30 minute incubation. Unlike the other four stains, using rhodamine 123 caused the cellular cytoplasm to fluoresce bright orange at a 510 nm excitation wavelength while the underlying dacron or expanded polytetrafluoroethylene demonstrated minimal autofluorescence. No inhibitory effect on cell attachment to plastic or subsequent cell growth in culture was observed. This technique can be utilized in the operating room to visualize part or all of an endothelial cell-seeded graft and to permit a quantitative as well as qualitative evaluation of the seeding process.

Title: Horizontal-takeoff transatmospheric launch system
IPC: F02K7/18
Filed: 1987-10-01
Abstract: This invention is directed toward providing a 
transatmospheric launch system that is essentially 
totally reusable, provides wide flexibility in choice 
of orbit, and may be launched quickly on short 
notice. The system of the invention is a two-stage 
horizontal takeoff and landing system. An orbiter 
vehicle (50) is integrated into the underside of an 
aircraft (2). Aircraft (2) has a cavity (4) opening 
aftwardly and downwardly to receive vehicle (50). 
Vehicle (50) and aircraft (2) are releasably 
connected by struts (30, 32). Aircraft (2) and 
vehicle (50) proceed to staging conditions under air 
breathing and then rocket power. Rocket engine (22) 
of aircraft (2) is throttled to produce a thrust 
differential with rocket engine (66) of vehicle (50). 
This differential causes vehicle (50) to 
automatically pivot away from aircraft (2) on struts 
(30, 32). After pivoting out of cavity (4), vehicle 
(50) is disengaged from struts (30, 32) and proceeds 
on its own to orbit. Aircraft (2) makes a 
conventional landing. Following reentry, vehicle 
(50) makes an unpowered horizontal landing. 
Separation is accomplished at a Mach number of about 
3.3. In a second embodiment, the main engine of the 
orbiter (50′) is a scramjet (101) instead of a 
rocket.
