Abstract: Method for calcining carbonaceous blocks into carbonaceous bodies, in which either a continuous or intermittent operation furnace is used. After placing carbonaceous blocks to be calcined onto the loading platform of a cart, a containment structure or enclosure structure is formed around the carbonaceous blocks including a barrier, which is held away from and is adapted to completely enclose the carbonaceous blocks, with the optional exception of barrier formed on the surface of the loading platform on which the carbonaceous blocks rest. The barrier being effective to prevent seepage of air or gases therethrough during calcination. The containment or enclosure structure for implementing the method comprises a conventional cart (4) for continuous and intermittent operation furnaces overlaid by a stacked arrangement including two side-by-side walls (6,6') of refractory material wherebetween a barrier (7) of carbonaceous powder is interposed, and a cover (8), including two slabs also formed from refractory material and arranged in two layers (18) wherebetween a further barrier of carbonaceous powder is provided. An additional barrier (5) of carbonaceous powder may be optionally provided on the loading platform (3) of the cart (4).

Abstract: Disclosed is an epoxy resin composition comprising, as basic components, (A) an epoxy resin, (B) a phenol-novolak resin, (C) a curing promotor and (D) a filler.  Pulverized or spherical silica having specific particle size characteristics is used as the filler (D). Preferably, a halogenated epoxy resin and antimony oxide are further incorporated in this epoxy resin.  This epoxy resin composition shows a very small molding shrinkage.  If a dialkylurea derivative is used as the curing promotor (C), the stability of the composition at about 100°C is drastically improved and the flowability of the composition is improved.  Accordingly, precision injection molding becomes possible, and the effect of sealing a semiconductor is enhanced.

Title: Engine system using refrigerant fluid
Inventor: ROBAR SHELDON
IPC: F02B75/02
Filed: 1990-12-31
Granted: 1996-06-18
Abstract: An engine system using refrigerant fluid is cap-able of utilizing the heat produced by an external high-efficiency hydrocarbon fuel combustion process.  The heat from that process is utilized to transform the refrigerant fluid from a liquid state to a gaseous state in a cycle which includes extracting work from the fluid in the gase-ous state in a high-compression-ratio piston engine.  The cycle further includes transforming the fluid in the gase-ous state back to the liquid state in a condenser, and then feeding that fluid under pressure to a heating chamber where the combustion process heat again returns it to the gaseous state at high pressure and temperature.  The engine system has a higher efficiency than hydrocarbon fuel com-bustion engines, and has particular application to use in automobiles.  One preferred refrigerant fluid for this engine system is 2,2,Dichloro-1,1,1,Trifluoro-Ethane.

Title: Device for determining and/or monitoring a predetermined contents level in a container
Inventor: PFEIFFER HELMUT
IPC: G01F23/28
Filed: 1991-03-13
Granted: 1996-07-09
Abstract: To determine and/or monitor a predetermined contents level in a container, at the height of the level to be monitored a region of the container wall is defined by a ring or frame which is attached to the outer side of the container wall in such a manner that it is in oscillatory mechanical connection with said container wall.  The region of the container wall enclosed by the ring or frame forms the diaphragm of a sensor which also comprises an electromechanical excitation transducer which when fed with an electrical voltage sets the defined diaphragm region into oscillations, and an electromechanical receiving transducer which converts the oscillations of the defined diaphragm region to an electrical AC voltage.  An evaluating circuit connected to the receiving transducer serves to initiate display and/or switching operations in dependence upon the frequency, the phase or the amplitude of the AC voltage emitted by the receiving transducer.

Granted: 1997-09-16
Abstract: The aim of  the present  invention  is to propose a method for regulating a brushless d.c.  motor which permits the current ripple of the motor to be reduced to a minimum. This is achieved by an arrangement in which a switchable semiconductor valve (Tr1, ..., Tr4) of the energized bridge arms is switched off for a period of time ts dependent upon the speed of the motor, when the reference value of the motor current (IM) is reached. Furthermore, by this means, the clocking frequency of the switchable semiconductor valves is minimized; in addition  to  increasing  the  service  life  of  the transistors, this helps to considerably reduce motor noise.

Abstract: ABSTRACT OF THE DISCLOSURE            METHOD AND APPARATUS FOR SIMULTANEOUS OUTPUT OF           DIGITAL AUDIO AND MIDI SYNTHESIZED MUSIC      A  method   and   apparatus   are  disclosed  for simultaneously outputting digital audio and MIDI synthesized music  utilizing  a  single  digital  signal processor.   The Musical Instrument Digital Interface (MIDI) permits music to be  recorded  and/or  synthesized  utilizing  a  data  file containing multiple serially listed program status messages and matching note on and note off messages.   In contrast, digital audio is generally merely compressed, utilizing a suitable  data  compression  technique,  and  recorded.   The audio  content  of  such  a  digital  recording may  then be restored by decompressing the recorded data and converting that  data  utilizing  a  digital-to-analog  convertor.   The method and apparatus of the present invention selectively and alternatively couples portions of a compressed digital audio  file  and  a MIDI  file to  a  single digital  signal processor which alternately decompresses the digital audio file and implements a MIDI synthesizer.  Decompressed audio and MIDI synthesized music are then alternately coupled to two separate buffers.   The contents of these buffers are then    additively    mixed    and    coupled    through a digital-to-analog convertor to an audio output device to create an output having concurrent digital audio and MIDI synthesized music.
