Title: Recording and display method and apparatus
IPC: B23K26/08
Filed: 1972-02-11
Abstract: An image comprising a multitude of small discrete holes is formed by a laser in a radiation absorbing film. Appropriate means form a large number of brief-duration, amplitude-modulated pulses of optical radiation. These pulses are then deflected and focused to form an array of discrete holes in a film, such as a 500 Angstrom thick layer of bismuth, on a polyester substrate. By varying the energy in each pulse, the size of the holes can be varied to form images having a gray scale.

Patent ES-409700-A1 (ES)
Title: Continuous feed medical nebulizer
IPC: B05B17/06
Filed: 1972-12-16
Abstract: A continuous feed nebulizer system for medical inhalation therapy in which a rigid dual lumen feed tube is connected with a liquid supply source and extends into a nebulizing chamber. This feed tube continuously replenishes liquid as it is nebulized and has a liquid drain lumen that is of a smaller cross sectional area and extends below an air return lumen. Constricted orifice structures adjacent a bottom of the liquid drain lumen and a top of the air return lumen damp out sudden changes of liquid level in the chamber as this level ranges between a bottom of the liquid drain lumen and a bottom of the air return lumen. This structure causes more uniform nebulization within the continuous feed nebulizer.

Title: Pressure control valve for hydraulic braking systems of wheeled vehicles
IPC: B60T8/36
Filed: 1974-08-09
Abstract: A pressure control valve applicable to anti-skid devices in automobile vehicles is provided with two hydraulically independent fluid circuits. One circuit controls the actuation of vehicle's brakes and the other circuit controls the braking effect of the vehicle's wheels to avoid skidding of the vehicle. Both circuits are related through the functions of two pistons, one piston being for storage to serve as an intermediary between a control fluid and a spring which accumulates energy and work as a differential piston, and the other piston being for the main actuation of the valve. The axial movements of the pistons allow the brake circuit fluid to compress or decompress as well as to open and close a valve which connects the conventional brake circuit to the anti-skid system.

Title: Interference protected electronic ignition system for an internal combustion engine
IPC: F02P7/077
Filed: 1978-06-29
Abstract: To eliminate the effects of disturbances, noise and interference in the signal derived from a speed-dependent signal generator coupled to the engine on the threshold response level of a threshold switch which, upon sensing a leading flank of the signal, causes a controlled transistor switch to turn ON to pass current through an ignition coil and, upon sensing the trailing flank of the signal, turns the switch OFF to induce an ignition pulse, a supervisory circuit is connected to the threshold switch which provides a bias voltage thereto so that the threshold switch will accurately and reliably respond to the trailing flank of the signal from the signal generator even in the presence of noise and interference voltages at a predetermined angular position of the crankshaft of the engine-absent a shift in the relative angular position of the signal from the signal generator and the crankshaft of the engine-to prevent failure of generation of an ignition pulse, or untimely, uncontrolled generation thereof. The supervisory circuit may include a control charge capacitor providing a bias voltage or, for example, a Schmitt trigger set to respond at different threshold levels of the threshold switch and, upon such response, to provide a bias voltage thereto, thus causing the threshold switch to respond upon response of the Schmitt trigger even in the presence of signal disturbances.
