Abstract: STACKED MOS DEVICES WITH POLYSILICON INTERCONNECTS  Abstract of the Disclosure A stacked metal-oxide-semiconductor (MOS) device has a lower source, drain and channel formed in a silicon substrate and an upper source, drain and channel formed in a deposited polysilicon layer which is recrystallized by laser annealing.  Instead of the conventional method of depositing aluminum interconnects between the device upper terminals and bonding pads, interconnect parts are formed in the recrystallized polysilicon layer itself.  This has the advantages of preventing junction distortion by undesired aluminum penetration into the silicon.  Also contact windows do not have to be opened directly to the source and drain terminals thereby easing design constraints.     - i -

Abstract: DELIDDABLE OVENABLE CONTAINER                 ABSTRACT OF THE DISCLOSURE         A deliddable ovenable container, such as a molded pulp tray with a liner obtained from a thin film of polyester, useful for packaging food to be frozen for sale and storage and subsequently heated by the consumer in either a microwave or a conventional oven, with means to insure that a trans-parent and flexible lid of polyester film sealed thereto by heat and pressure subsequently can be peeled away from the polyester liner of the tray without any undesirable delamination of the liner from the molded pulp base of the tray, either at freezing temperatures before heating or at high temperatures after heating, to expose the food for consumption.  Such means includes a coating of release material having adhesive properties, such as methyl cellulose, on the liner outside the area where the lid is to be sealed to prevent strong adherence between the lid and the liner at the extreme edges of the tray, the release material ideally having fiber adhesive properties as well and being applied to the cut edge which strengthens the mechanically trimmed fibrous material around the edge of the molded pulp base, plus increased density of the fibrous material only around the zone of the release material and the lid seal so that the fibrous material additionally resists being pulled apart in that area while still providing a thicker thus stronger tray elsewhere which resists bending forces.

Abstract: VARIABLE RATE SPEECH SYNTHESIZER                   ABSTRACT OF THE DISCLOSURE In a speech synthesizer, a method and apparatus for varying the intonation of a word or a phrase relies on the generation of pitch frequencies independent of the formant frequencies of synthesized speech.  Pitch frequency is controlled and varied in successive repetitions of a phrase by reference to an external timing reference, such as a stored tables of pitch frequencies as functions of time. At each repetition of a phrase, a different repetition rate produces successive repetitions of the same phrase with desired variations in intonation.  The invention finds application in both time domain speech synthesis and frequency domain speech synthesis.

Abstract: DITCHING APPARATUS WITH IMPROVED DITCHING BLADE  Abstract of the Disclosure The ditching apparatus includes a prime mover  (A)  and an arm assembly (B) for selectively positioning a ditching head (C).  The ditching head includes a rotatably mounted circular supporting  member  (34)  to  which  a  plurality  of  mounting brackets  (44)  are mounted  transversely and radially about an axis of rotation (36).  A plurality of blades (50) are mounted to the brackets by a plurality of bolts (84).  Each blade has first   and   second   faces   (66,   68)   which   are   disposed symmetrically about a face axis (78).  The faces terminate at first   and   second   edges   (52,  54)   which   are   disposed symmetrically about an edge axis (56) and at first and second ends (60, 62) which are symmetric about an end axis (64).

Abstract: ABSTRACT OF THE DISCLOSURE A unique solvent blend and method of conducting vapor degreasing operations is disclosed, wherein synergism is obtained by the addition of a component to three known vapor degreasing solvents.  The vapor degreasing solvents of the invention comprise a blend selected from the group consisting of perchlorethylene and trichlorethylene or 1, 1, 1, trichlorethylene and methylene chloride or methylene  chloride and trichlorethylene.  The trichlorethylene or methylene chloride component comprises about 0.1 to 90 volume percent of the total degreasing solvent, while the other component of the blend comprises the remainder of the solvent blend.          The resulting vapor degreasing solvent, has a number  of advantages over perchlorethylene alone or 1, 1, l trichloro-ethane alone, or in combination with stabilizers, or tri-chlorethylene alone, or in combination with stabilizers.          Addition of either trichlorethylene or methylene chloride to the solvent blends of the invention extends the normal life of the degreasing solvents alone, or in combination with conventional stabilizers and the like.  The degreasing sol-vent blend of the invention not only extends the operational life of perchlorethylene of 1, 1, 1 trichloroethane or trichlorethylene based vapor degreasing solvents, but also reduces the cost of  conducting vapor degreasing operations using the conventional vapor degreasing solvents, because initial operational temperatures, for effective vapor de-greasing, are reduced.  The unique solvent blends used in the method of the invention  evidence unique results when used in vapor degreasing process wherein one of the components of each of the novel blends is found  to stabilize the other components of the blend in the presence of contaminants en-countered in the conventional vapor degreasing process.

Abstract: ABSTRACT OF THE DISCLOSURE            In a cooling column  the feed material to be dried or cooled is intermittently transferred from any one sieve bottom to a subjacent   sieve bottom as by tilting individual sectors of the respective sieve bottoms.  As a result, the feed material comes to rest on the sieve bottoms with a non-uniform bed thickness, resulting in a non-uniform drying or cooling, respectively, of the feed material.  A substantially uniform bed thickness of the feed material on the sieve bottoms is therefore desirable. This is achieved by the invention by providing a leveling rod mounted in support means for oscillating movement about a stationary pivot axis and extending substantially transversely of the direction of movement of the feed material.

A multiplier low pass filter circuit is coupled to the output from the multiplier circuit for deriving from the pulse width modulated and amplitude modulated product signal an average value power signal V where V = VI Cos .theta., V is the load voltage, I is the load current and .theta. is the load impedance phase angle.  An analog-to-pulse rate converter is supplied the average value power signal V and serves to convert it into a high frequency train of output signal pulses wherein each output signal pulse represents a predetermined quantized amount of electric energy.  An automatic offset error correction circuit comprising polarity reversing switches is responsive to Abstract of the Disclosure - Continued the output from the analog-to-pulse rate converter for automatically switching the polarity of the average value power signal V supplied to the analog-to-pulse rate converter midway through the quantizing period of the analog-to-pulse rate converter to cause an up/down integration of the average value power signal V over each quantizing period of operation and simultaneously producing a sequential addition/subtraction of like polarity offset error signals over each quantizing period of operation to thereby cancel out the offset error signals automatically.  A watthour indicator is coupled to the output from the analog to pulse rate converter and a watt indicator is coupled to the output from the multiplier low pass filter circuit for deriving respectively indications of the kilowatt hours and watts of energy being supplied by a source of electric energy being measured.
