Abstract: NON-ABRASIVE MAGNETIC HEAD CLEANING SYSTEM           ..  .  .       ABSTRACT OF THE DISCLOSURE          A cleaning system for flexible disk equipment or the like.  The system includes a cleaning disk made of an absorbent and porous fibrous material which has an area sub-stantially saturated with a liquid cleaning solution.  The cleaning disk is rotatably supported within a flat jacket. The jacket includes opposed openings on either side so as to expose a portion of the cleaning disk to enable the disk to come into contact with a magnetic head or heads.  At least one of the openings is enlarged to expose a relatively large portion of the surface of the cleaning disk, so as to facili-tate complete saturation of an area of the cleaning disk with a liquid cleaning solution while leaving a portion of the cleaning disk dry.  The jacket containing the disk is placed within a flexible disk system which rotates the saturated disk,  thus causing the magnetic head(s) to be cleaned in a non-abrasive fashion with a wet, dry, wet action.  An improved jacket for use with a thickened cleaning disk is also disclosed.

Abstract: Abstract of the Disclosure.             The hand pressing device comprises a pressing die in the form of an open-topped rectangular box (1 ) with a loose perforated bottom plate (2) . The inner walls of the box (1 ) are smooth. The box (1) can be filled with soaked waste paper, particularly old newspapers. As pressing element is used a loose pressing plunger (4) with a flat perforated bottom (9). This can be pressed into the box (1) down to a predetermined penetration depth, whereby water is squeezed out of the soaked paper and can escape both upwards through the perforated bottom (9) of the plunger and downwards through the perforated bottom plate (2) of the box (1). Thereby a briquette of predetermined dimensions and predetermined density is produced. Upon withdrawal and removal of the pressing plunger (4) and inversion of the box (1) to upside down position, the briquette thus produced can readily be pressed out of the box (1) by exerting a thumb pressure on the loose bottom plate (2), the side and end faces of the briquette sliding along the inner wall of the box (1) at low friction and without being torn up. After drying in the air, the briquette forms an excellent fuel for fireplaces and stoves.

Abstract: STEAM INJECTION METHOD AND APPARATUS                    FOR RECOVERY OF OIL                   ABSTRACT OF THE DISCLOSURE           A method and apparatus for recovering oil from an oil bearing formation utilizing steam injected into the formation.  A working fluid is heated at the surface to produce a reversible, chemical reaction, particularly a reforming reaction in a reforming/methanation reaction cycle.          The products of the reforming reaction are transported at near ambient temperatures to a downhole heat exchanger through which water is circulated.  There a catalyst triggers the methanation reaction, liberating heat energy to convert the water to steam.  The products of the methanation reaction are recirculated to the surface to repeat the cycle.  In one embodiment the products of the methanation reaction are injected into the formation along with the steam.  Va-rious catalysts, and various systems for heating the working fluid are disclosed.

Abstract: DATA LINK USING INTEGRATED OPTICS DEVICES            Abstract A transmission link is established between remote electrical transducers, e.g., underwater, and a monitoring receiver, e.g., shore-based over an optical fiber link using integrated optical waveguides.  Optical directional couplers with absorber and reflector elements incorporated in the waveguides at respective terminals of the transmission link permit the injection of light into the fiber at the monitoring terminal and the modulation of reflected light at the transducer terminal in accordance with an electrical signal from the transducer.  No electrical energy then needs to be transmitted between the monitoring and transducing terminals of the transmission link.  The link itself is thus light in weight and free of electrical currents subject to electromagnetic interference.
