Abstract: Abstract An elongated cylindrical housing is arranged to be mounted adjacent to and parallel with the surface of a moving abrasive member and has a row of ports establishing communica-tion between the interior of the housing and its exterior.  An elongated cylindrical core member is rotatably supported in the housing and has a spiral groove in its surface of a selected width and pitch such that a small number of ports are exposed to the groove at a time to form a narrow jet.  Fluid under pressure is supplied to the groove and upon rotation of the core member the jet of fluid travels across the surface of the moving abrasive member to clean it.  A cam is provided in the present apparatus to reciprocate the housing in its longitudinal dimen-sion through a distance approximately equal to the spacing of the ports so that the surface of the abrasive member between the ports is also cleaned.

Abstract: CIRCUITS AND METHODS FOR MULTIPLE CONTROL IN DATA PROCESSING SYSTEMS                Abstract of the Disclosure In a data processing system in which two or more asynchronous processors operating as masters interchange requests and responses with a control unit that in turn controls a number of peripheral devices and operates as a slave to the processors, repetitive requests from a high speed processor can give rise to an impasse condition in which the control unit is blocked from completing the pre-viously initiated sequence between a peripheral device and another processor.  In accordance with the invention, the interface between the processors and the peripheral devices incorporates means which detect an uninterrupted sequence, of predetermined length, of busy responses from the control unit. If such responses are not interrupted by other actions, the system temporarily exercises independent con-trol, returning a busy signal to the processors while en-abling the control unit to ascertain whether reconnection to a specific processor is needed as the next step in a pre-viously initiated processor program.  If so, the control unit is enabled within the predetermined interval to effect the reconnection, either within the allotted time or on a succeeding repetition of the cycle.  The exercise of a limited initiative for a predetermined time interval does not alter the basic master-slave relationship or unduly delay data transfer operations.

Abstract: ABSTRACT           Thermal isolation of a cryostat is improved for a superconducting solenoid having a plurality of separately energizable coils or winding sections by reducing the number of conductors required to selectively energize the persistence switch controlling a particular winding section.  As a con-sequence, the dimensions of the vent and fill tube openings of the cryostat which accomodate these conductors may be reduced.  In one embodiment a diode is incorporated in series with heating element of each switch.  The switches are connected ?o form a steering network to control as many as p?n(n-1) separate coils using n conductors to actuate p persistence switches.  In another embodiment n(n-1)/2 coils are similarly controlled with n conductors using the time-current response of persistence switches without diodes.  Still another embodiment utilizes a binary to hexadecimal converter within the cryostat to permit n externally generated signal conductor to select as many as p ? 2? -1 persistence switches.

Abstract: ELECTROMAGNETIC BAND CLUTCH     ABSTRACT OF THE DISCLOSURE         An electromechanical clutch for vehicle engine cooling fans includes a driving member mounted for rotation by the vehicle engine and a driven member rotatably mounted on the driving member.  The driven member carries the engine cooling fan.  One end of a metal band is connected to the driven member, and wraps circumferentially around the driving member in the direction of rotation of the latter.  An electromagnetic coil comprising windings wound circumferentially around the driving member and rotatable therewith exert an electromagnetic force on the band when current is transmitted to the coil, drawing the band into engagement with the outer circumferential surface of the driving member, to thereby engage the clutch and cause the engine cooling fan to be rotated with the driving member,  Because of the wrapping effect of the band when it engages the outer circumferential surface of the driving member, the electromagnetic force necessary to actuatz the clutch is multiplied as the clutch is engaged through the servo action caused by the band wrapping around the driving member.  The electrical signal is transamitted to the coil through a slip ring, and is controlled by conventional engine temperature and/or pressure sensors.

Abstract: ABSTRACT         A system for transmission and display of texts on a television screen enables a display of a magazine made up of several pages.   The packets of data relative to one page are transmitted without being multiplexed with the packets from another page of the same magazine   The data of one page begins with a page flag which is followed by data indicating the number of the page and ends with the flag of the following page.   The data from each page is grouped in rows, preceded by a row flag. Each page contains an order row of the data which is operation data and is not used for display.   Certain pages contain only the data which is relative to the shape of characters of the alphabet and the pages are not for display.   They include in their order rows a specific operation octet which is recognized in the receiver.   Responsive to this page, the system switches the subsequent data from the alphabet page towards the writing circuit of one of many shape memories, in order to record there the character shape data.

Abstract: 5D-5574 SHEAR RESISTING CABLE WITH TRANSPOSED STRANDS AND METHOD OF ITS MANUFACTURE A heat shrinkable polymeric material is wrapped around a plurality of adhesive coated wire strands placed together in a transposed configuration prior to heating the strands to cause the adhesive to melt and cure.  The shrink initiation temperature of the polymeric material is selected to exceed the temperature at which the adhesive melts while preceeding the temperature at which the latent catalyst initiates the cure cycle.  The shrinking of the polymeric wrapping causes the transposed cable strands to become compacted and substantially increases the surface area of the strands in contact with the adhesive material.

Inventor: HEASLETT ALASTAIR M
IPC: G11B27/28

Granted: 1982-06-01
Abstract: ABSTRACT OF THE DISCLOSURE         An audio signal is sampled, quantized and the values are stored in a specific digital data block/sub-block format on alternate tracks of a recording medium.  The block/sub-block format provides an inherent simplification of error correction techniques, and consists of dividing the digital audio data into groups of digital words, and recording alternate words on separate tracks in the medium.  Cyclic redundancy check characters, synchronization, and parity information are selectively interspersed with the data to define sub-blocks which in turn are combined into separate blocks of the block/sub-block arrangement.  On reproduce, any errors, dropouts, etc., are detected and corrected or concealed to reconstitute the original audio signal.  Editing is facilitated by the separated block arrangement which allows entering and exiting the record mode without destroying any data.

Abstract: ABSTRACT OF THE DISCLOSURE A method of making sintered powder metal parts which particularly includes a hot forging step, is disclosed.  Selected powders of a predetermined particle size distribution, are blended and agglomerated by cold compaction into a preform.  The preform or briquette is then coated with a thin shell of a chemically inactive radiation absorbing material, preferably graphite, under ambient conditions.  The coated briquette is then sintered in a continuous through-put furnace with the temperature maintained at a level of at least 2000°F and the part being subjected to the furnace heating for a period of 5-30 minutes.  The sintered part may then be subjected to direct hot forging with the retained temperature of sintering utilizing the graphite coating as a die lubricant, or the sintered part may be cooled and then subsequently reheated for hot forging, again utilizing the retained graphite coating as a die lubricant. If hot forging is not to be employed, the graphite particles are removed such as by brushing so that sizing, machining or grinding may be carried out without the presence of the graphite coating.
