Title: Catalytic olefin hydration for ether production
Inventor: BEECH JAMES H JR
IPC: C07B61/00
Filed: 1991-07-22
Abstract: An improved process for the production of dialkyl ether in which a lower alkylene feedstock and water are contacted in a catalytic reaction zone with a porous solid acidic olefin hydration catalyst under olefins hydration and etherification conditions. The improvement comprises: recovering a first fluid effluent stream from the fixed bed reaction zone; splitting the first fluid effluent stream into a liquid product recovery stream and a fluid recycle stream; and passing the fluid recycle stream comprising olefin, alcohol and ether in effluent stream proportions for feeding to the reaction zone along with fresh olefinic feedstock and water, wherein the amount of fluid recycle stream is sufficient to maintain a homogeneous single fluid reaction phase in the reaction zone for further conversion with propene. The preferred solid catalyst comprises an acidic zeolite, such as zeolite Beta.

Title: Process interface system
Inventor: FRIDHOLM KENNETH
IPC: H01R25/14
Filed: 1991-08-20
Abstract: The present invention relates to a process interface system (1), in which single-channel modules (D, A) designed on the basis of compact IC technique are housed in terminal block-like blocks of the same type as standard terminal blocks (6a-6d) for mounting rails (4). The single-channel modules (D, A) are designed in few different versions which are programmed during installation for their field of use as AI or AO interface unit and as DI or DO  interface unit, respectively, as well as for their voltage range. Each interface unit communicates directly with the system computer (PC) via a serial bus (2) in the form of electrically conducting paths (5a, 5b, 5c) applied to the mounting rail (4) on which the respective interface module (D, A) has been mounted. The modules are supplied with power also through conducting paths (5a, 5b, 5c) on the surface of the mounting rail. Connection of transducers (3a, 3d) is made direct to the respective interface module. The terminal blocks (6a-6d) can be freely mixed with the interface modules (D, A) for, for example, voltage distribution to the transducers.

Patent CA-2093514-A1 (CA)
Title: Coating of hydrophilic interpenetrating networks
Inventor: IQBAL MOHAMMAD
IPC: B41M5/50
Filed: 1991-09-13
Abstract: This invention relates to transparent materials that are capable of absorbing liquids, and, more particularly, to materials that can be used as ink-receptive layers for transparent imageable materials. Compositions useful as transparent liquid absorbent materials have been formed by blending a liquid-insoluble polymeric material with a liquid-soluble polymeric material. The liquid-insoluble material is presumed to form a matrix, within which the liquid soluble material resides. A problem that frequently arises in the formulation of polymer blends is the incompatibility of the polymers being blended. When attempts are made to blend polymers that are incompatible, phase separation occurs, resulting in haze, lack of transparency, and other forms of nonhomogeneity. This invention provides polymeric networks comprising blends of polymers wherein at least one of the polymers of the blend is crosslinked, after blending, to form a continuous network throughout the bulk of the blend, the uncrosslinked components of the blend being intertwined in such a way as to form a macroscopically homogeneous composition. Substantially all of the crosslinking occurs after the polymeric blend is coated and dried to a continuous film in contrast to crosslinking in solution, thereby providing an easily coatable solution without gelation. The integrity of such networks persist even after absorption of solvent. These materials can be used to form durable, non-tacky, ink-absorbent, transparent coatings for graphical materials.

Patent CA-2095201-A1 (CA)
Inventor: LEDET BRENT A
IPC: A23L3/18
Filed: 1993-04-29
Abstract: Shrimp and other food products carried on a plastic modular conveyor belt are efficiently cooked at atmospheric pressure in the presence of saturated steam protected by a confining receptacle from dilution by insulating air. The steam condenses by transfer of cooking energy, the condensate dropping downwardly in the receptacle by gravity. By passing products through the constant 212 degree F saturated steam zone residing at the upper portion of the cooking receptacle, the belt speed and distance through a modular cooking compartment control the cooking time for uniform production. The steam is replenished through a proportional flow valve to replace only that amount of steam expended in cooking. Thus, temperature is sensed at a cooler position under the saturated steam cooking zone where temperature is typically 190-200 degrees to detect variations of the amount of steam condensed in exchange of heat in cooking the product, and to proportionately control the flow of replacement saturated steam. Critical control of cooking receptacle rejection or contaminating air maintains a substantially static pure saturated steam layer in the upper portion.  The lower portion contains lower temperature air/vapor mixture. The access doors are sealed by an expandable gasket tube. This permits simplified fully automatic steam replenishment and efficient cooking without losses of energy from either excessive steam flow, dilution of saturated steam cooking efficiency from air or fluid vapors admitted into the cooking receptacle or losses at the doors.

Title: A Dynamic Thermal-Mechanical Material Testing System Utilizing a Balanced Magnetic Field

IPC: G01N3/10
Filed: 1992-04-28
Abstract: Apparatus  (100)  for  a  dynamic  thermal-mechanical material  testing  system  that  not  only  self-resistively heats and deforms a specimen (170), both under controlled conditions, but also substantially reduces adverse affects in  specimen  performance,  such  as  magnetically  induced motion  and  non-uniform  specimen  heating,   that  would otherwise result from magnetic fields which impinge upon the  specimen  and  are  caused  by  high  heating  currents flowing in the apparatus.   This reduction is achieved by spatially   locating   high   current   carrying   conductors (102,102') used in the apparatus such that these conductors collectively   generate   substantially   balanced,    i.e. substantially equal, and opposite magnetic fields (431,433) that  effectively cancel  each  other  out  in  a  volumetric region in the apparatus which contains the  specimen and particularly its work zone.

Abstract: Successive frames of data (10) are processed to provide a plurality of data streams (27, 29) containing the data in different orders. In an illustrated embodiment, two different data streams (27, 29) are output for incoming frames of video data. Pixels are grouped from an incoming current video frame to provide successive pairs thereof for storage in a first memory bank (16) at a first clock rate  phi  . Stored pixel pairs are read from a second memory bank (18) containing a previous video frame at a second clock rate 2  phi  while the pairs of pixels from the current video frame are being stored in the first memory bank (16) at rate  phi  . This provides two pairs of pixels from the previous video frame for each one pair of pixels stored from a current video frame. The pixel pairs from the previous video frame output from the second memory bank are combined into two data streams, each providing the pixels in a different order.

Title: Mouthpiece for inhalation therapy device
Inventor: BRUGGER STEPHEN
IPC: A61M16/06
Filed: 1994-05-27
Abstract: Abstract MOUTHPIECE FOR INHALATION THERAPY DEVICES     The invention concerns a mouthpiece for inhalation therapy devices. An opening (14) is located on the basic body (1) of the mouthpiece for exhalation into the mouthpiece so that the exhaled air can escape through it. The opening (14) is covered by a flat, elastic valve element (12) of a nonreturn valve (11) in such a manner that, for the most part, a simulation of the missing wall of the basic body (1) in the area of the opening (14) is achieved. This insures that the flow conditions in the interior of the mouthpiece remain nearly unaffected by the opening (14) when, during inhalation, the flat, elastic valve element (12) lies flat on a level wall section of the basic body (1) and closes the opening (14).
