The sheet passes under an endless track of transversally extending bars having a pattern of hexagonal cells cooperatively formed in their outer faces.  The bars are mounted to chains which are entrained about sprockets that are driven to match the surface speed of the sheet conveyor.  Intermediate the longitudinal extent of the lower run of the track of cutter bars, the cutters are gradually cammed down to abutment with the sheet conveyor, and gradually out of the sheet.  At the downstream end, the hexagonal patties move over a fluidized bed-type transfer plate onto a take away conveyor, e.g. into a blast freezer, as a narrow selvage at both lateral margins drop away for recycling.  As the patties are cooked, they become approximately if not perfectly round, displaying an appearance and texture more like hamburgers from homemade, handformed meat patties.

Title: Apparatus for mixing dispersed flows prior to their entry into a catalyst bed
Inventor: FROHNERT HEINZ
IPC: B01J8/04
Filed: 1987-06-30
Granted: 1991-09-03
Abstract: ABSTRACT   An apparatus for the catalytic treatment of products that contain hydrocarbons, using gases that contain hydrogen that are at an elevated pressure and temperature, the gas and/or vapour currents, including the liquid fractions that are dispersed therein, are carefully mixed prior to being brought into contact with a catalyst bed that is arranged in a column-type fixed bed reactor.  In order to avoid the large-volume unevenness in the product that is fed in, which is coarsely mixed with quench gas, the so-called skeins, in particular those that result in part from the unilateral segregation of gas, vapour and liquid in the preceding catalyst bed, are collected into an overall current on a collector base which covers the cross section of the reactor, are passed through an adjacent mixing tube as well as a tubular shell, and then diverted in the reverse direction of flow to enter a spaced located above a distributor system and are thus distributed over the cross section of the reactor with the liquid fractions that have collected on the distributor system, and are finally passed to a catalyst bed that is arranged beneath this.

Abstract: Abstract A process for the hydrolysis of polymers of acetoxy-styrene to polymers of vinylphenol which comprises:  (a) reacting a polymer of 4-acetoxystyrene with ammonia at a temperature of about 50° to about 150°C for a time sufficient to hydrolyze the acetoxy groups to phenol groups; (b) contacting the polymer with wet carbon dioxide gas at a temperature of about 110°c to about 180°C to form ammonium carbonate which immediately decomposes to ammonia, carbon dioxide and water; and (c) removing the decomposition products by sparging with nitrogen or by distillation.  This process provides a route to obtain polymers of vinylphenol both free from any hydrolysis reagents and containing high proportions of vinylphenol groups.  Polymers of vinylphenol are known compositions which have been used, for example, in the manufacture of metal treatment compositions, photoresists, epoxy resins and epoxy resin curing agents.

Title: Process for membrane separation of gas mixtures
Inventor: SAUER RICHARD A
IPC: B01D53/22
Filed: 1987-10-26
Granted: 1993-04-06
Abstract: ABSTRACT               A method for the substantial separation of at least ore gas component from a gas mixture to generate a residue gas substantially depleted of said gas components.  A semipermeable membrane is provided which has a feed gas side and a sweep gas side.  The feed gas side is contacted with a feed gas mixture containing at least one gas to be retained and at least one gas to be separated therefrom. The sweep side is simultaneously contacted with a sweep gas having a pressure lower than that of the feed gas.  The partial pressure of certains gas components present on both sides of the membrane are balanced to cause the remaining gas components to diffuse in either direction across the membrane depending upon their differential partial pressures.

Title: Snow skate
Inventor: GAHAN JOHN A
IPC: A63C5/00
Filed: 1987-11-06
Granted: 1991-04-02
Abstract: ABSTRACT OF THE DISCLOSURE         An article of footwear for travel over snow has a snow blade with front and rear support platforms spaced apart longitudinally of the snow blade for supporting front and rear portions, respectively, of the user's foot. The front and rear support platforms are secured to the snow blade so as to be movable towards and away from one another in response to flexure of  the snow blade to facilitate walking by the user.

Title: Sealed chambers
Inventor: MOKRY PIERRE
IPC: G10K9/12
Filed: 1987-11-19
Granted: 1991-02-19
Abstract: Abstract of the Disclosure The invention relates to chambers which are sealed against ingress of water and are provided with an element through which air may permeate to equalise pressures of air inside and outside the chamber.  The element is of a foamed silicone and has a cellular fine pored layer of predominantly open cells having a skin to be contacted by air outside the chamber.
