Title: Horizontally-oriented, opposed motion, balanced-at-impact punch press
Inventor: MEYERLE GEORGE M
IPC: B21D28/00
Filed: 1991-06-28
Abstract: A punch press has first and second opposed tools mounted on first and second members, and these members are movable toward opposite sides of material to be formed between the tools. These motion members are electromagnetically driven with rapid acceleration toward each other for impacting fast-moving first and second tools simultaneously against opposite sides of the material to be formed. The two opposed motion members with their respective electromagnetic drives are arranged for the momentum of the first tool with its associated moving parts at the instant of impact to be substantially equal to the momentum of the second tool with its associated moving parts so that equal and opposite impulses resulting from the respective momentums substantially cancel each other out. As a result of this opposed motion with momentums-balanced-at-impact, very little energy or work is wastefully lost into a platform or other support for the punch press, and only an insignificant or very modest amount of mechanical shock and vibrations are induced into the platform or other support. Thus, little noise is transmitted into the environment via the platform or other support. The material is fed into the region between the first and second tools by a feed mechanism which is also movable in either direction. Various arrangements are disclosed for appropriately positioning the feed plate between the opposed tools and for controlling their respective electromagnetic drives for achieving substantially simultaneous impact of the tools with substantially equal momentums against opposite sides of the material to be formed between the tools.

IPC: H03F1/32
Filed: 1993-01-15
Abstract: For supply to first and second feedforward distortion compensating circuits 33(1), 33(2) connected in parallel, a two-divider 31 divides into signals of a common phase and a common amplitude an input radio frequency signal supplied to an input terminal 11.  A two-combiner 35 combines component outputs of the feedforward circuits in inphase as an amplified output signal which is supplied to an output terminal 13.  In general, N feedforward circuits (N being an integer not less than two) are connected in parallel and are supplied with the input radio frequency signal through an N-divider.  Component outputs of the feedforward circuits are combined in inphase as the output signal by an N-combiner.  Alternatively, the input radio frequency signal is divided into signals of a predetermined phase difference and of a common amplitude by the N-divider.          In this case, the component outputs of the feedforward circuits are combined in a phase of cancelling the predetermined phase difference by the N-combiner.

Filed: 1993-01-29
Abstract: In  a tool  for removing  frost on  an automotive's window or wind-shield,  it is known  to have  a straight edge  which is  pressed  against the  surface  and moved forward  and   backward  to  remove  frost.     In  this invention,   the  straight   edge   is  replaced   by  a combination  of  left-hand   and  right-hand  screw-like (helical) ridges.  When this combination is placed on an automotive's window or wind-shield and  is rotated about its  axis, the  helical ridges move  on the  surface and remove the  frost in the directions parallel to the axle of said  combination.  The combination  of left-hand and right-hand  helical ridges  is desired  for neutralizing lateral forces which result  directly from the action of removing frost by said ridges.

Title: Cooperative conveyor system for canter and saw
Inventor: KNERR MICHAEL P
IPC: B23D59/00
Filed: 1993-03-17
Abstract: ABSTRACT OF THE DISCLOSURE      A cooperative conveyor system for a lumber production line.          The production line has a canting station and a sawing station spaced at a distance from each other and interconnected by a powered conveyor system.    The cants are fed at a higher rate through the canting station than through the sawing station.  The conveyor system is arranged to receive cants from the canting station at a high feed rate and transport the cants to and into a sawing station at a lower feed rate.  The cants are fed through the canting station at controlled intervals so that the resulting gap between succeeding cants received on the conveyor are at a desired spacing to maximize the production of the sawing station. The cant exiting from the canting station is forced to overrun the conveyors feed rate and thereby reduces the gap between it and a preceding cant. The conveyor then transports the cant to and into the sawing station at the desired feed rate for the sawing station.  In one embodiment, the sawing station has two saws. The conveyor system is arranged to  shift the  cant  exiting the canting  station  into alignment with the saw selected to perform the sawing operation.

Title: Process for the production of tertiary alkyl ether rich fcc gasoline
Inventor: LE QUANG N
IPC: C10L1/185
Filed: 1993-05-25
Abstract: Abstract of the Disclosure A process is disclosed for the production of alkyl tertiary alkyl  ethers  in  C4+  hydrocarbon  streams  rich  in  isoolefins, typically  containing  catalyst  deactivating  amounts  of  dienes and/or   compounds   containing   heteroatoms.   The   process   is especially advantageous  in extending the cycle length for the zeolite  catalyzed  etherification  of  isoolefins  in  C4+  FCC gasoline by reducing catalyst aging.  It has been discovered that if hydrogen  is co-fed with the alkanol  and C4+ isoolefin rich feedstreams  to  an  etherification  reaction  catalyzed by  acidic zeolite wherein the zeolite has  been  impregnated with a noble metal  the rate of catalyst aging or deactivation is stantially lowered.   The process  is  especially effective,  i.e.,  catalyst aging  is  particularly reduced,  when  hydrogen  is co-fed  to  an etherification  reaction  using  acidic  zeolite  Beta  catalyst containing palladium.

Inventor: DYKAAR DOUGLAS R
IPC: G01R1/07
Filed: 1993-08-31
Abstract: This invention embodies a new electro-optic sampling probe with femtosecond resolution suitable for ultra-fast electro-optic sampling. The new probe is several times thinner and has a dielectric constant four times less than the best reported conventional bulk LiTaO3 probes. In addition, the ultimate bandwidth is50 percent greater than an equivalent LiTaO3 probe. The probe is a thin film of Alx Ga1-x As used in both total internally reflecting and free-standing geometries. Here x is chosen for sufficient transmission of the crystal to the wavelength of the laser source being used for electro-optic sampling. The thickness of the film is a small fraction of the thickness of prior art probes and is chosen, for speed andsensitivity of electro-optic sampling, to be thin compared to the spatial extent of the laser pulse. The thin film probe eliminates many of the problems associated with the use of bulk crystals as electro-optic sensors.
