Title: Method for suppressing the harmful effects of metal contaminants on hydrocarbon conversion catalysts using a strontium colloid system
Inventor: KUGLER EDWIN L
IPC: B01J29/08
Filed: 1987-12-04
Granted: 1992-01-07
Abstract: ABSTRACT OF THE DISCLOSURE          A strontium colloid system is introduced into a  hydrocarbon  conversion process  to  suppress  the harmful effects of one or more metal contaminants in the hydrocarbon feedstock on the active component(s) of the catalyst used in said process. The strontium compound in the colloid system reacts with or traps the metal contaminants before they contact the active component(s)   of  said  catalyst,  thereby  reducing catalyst  deactivation,  coke  make  and  hydrogen production relative to that obtained had said compound been introduced into the process in non-colloid form. In a preferred embodiment, the strontium colloid system is introduced into the reaction zone of said process and,  preferably,  with at  least a  portion  of  the hydrocarbon feedstock to said process.

Abstract: IN THE  CANADIAN         PATENT AND TRADEMARK OFFICE    PATENT APPLICATION     entitled : Edible film-coating agent, process for coating foodstuff with this agent and appli-cation to the preservation of foodstuffs. in the names of : Robert RIZZOTTI, Gerard TILLY              ABSTRACT OF THE DISCLOSURE        This invention relates to an edible film-coating agent for coating foodstuffs, agent based on gelatin, a polysaccharide selected from carragheenans, galacto-mannans, xanthans and mixtures thereof, or alginates, pectins and mixtures thereof. A plasticizing polyol, such as glycerol or sorbitol, and conventional food additives may be added. A film of film-coating agent is deposited on the pieces to be coated by immersion, pain-ting or spraying. In the case of alginates and pectins, the coating of the pieces of food by the film-coating agent must be followed by a treatment with Ca++ ions, The agent is more particularly used for the presentation and preservation of perishable foodstuffs.

Abstract: ABSTRACT OF THE DISCLOSURE:            A contact lens or intraocular lens made from a lightly crosslinked polymer of 2-hydroxyethyl methacrylate or from its  copolymer,  where  the  2-hydroxyethyl methacrylate component prevails over the second nonhydrophilic component, has improved surface layer characteristics.   The lens contains a hydrophilic, swellable, transparent surface layer and an inner part of lower swellability than the surface layer.  The swellability of the surface layer decreases continuously from the surface towards the inner part to the swellability level of the inner part.  The swellability of the surface layer may be up to 98% at the surface and the thickness of the surface layer may be as high as 100 µm. The finally shaped lens is treated with an alkaline reacting solution of a salt, in which the lens does not swell.  The lens is then freed of all soluble substances by washing.

Title: Process and a device for the filling of doughy filling material into receptacles
Inventor: BARNEWITZ MANFRED
IPC: B65B43/58
Filed: 1988-06-03
Granted: 1992-01-28
Abstract: ABSTRACT OF THE DISCLOSURE 1. A process and a device for filling receptacles with doughy filling material. 2.1  Doughy  filling  material is  pressed  through  a filling head in the form of  a nozzle,  whose outlet opening corresponds approx. to the cross-section of the receptacle bottom into the receptacle pushed on the nozzle which receptacle is pushed back by the material pressed  in  from  the  filling head  in  a  declerated movement.   Inhomogeneous  filling  material  is  not sufficiently homogenized and compressed thereby. Air inclusions remain in the filling material filled in. Due  to  the  spatial conditions  these  nozzles  can furthermore not be equipped with a cutting means for separating  the  filling  material  strand  after  the filling operation.   2.2  To  fill  receptacles  uniformly,   without  air inclusions and without soiling, the filling material is pressed into the continuously enlarging space between the receptacle bottom and a counter-bottom attached to the  end of  the  filling head  facing  the  receptacle bottom and eccentrally traversed by the outlet opening and at the same  time the  counter-bottom is  rotated relative to the receptcle by the central axis.   2.3 The process and the device are especially suited for  filling  in viscous pastelike  and  inhomogeneous filling material.

Abstract: The apparatus for forming an imbricated product formation, in which the pitch or spacing between successive printed products is essentially constant,  comprises two successively arranged conveyors.  A scanning device detects the arriving printed products and delivers for each printed product a signal to a measuring unit.  This measuring unit determines the repetition frequency of the signals produced by the scanning device and delivers such to an evaluation circuit.  In the evaluation circuit the determined repetition frequency is multiplied by a signal proportional to a predeterminate pitch or spacing between the products and the resultant multiplication product is delivered to a motor regulator.  This motor regulator compares this resultant multiplication  product with a  signal  delivered by  a tachogenerator and regulates a drive motor such that the conveying velocity of the second or downstream conveyor of the two successively arranged conveyors is adjusted such that the pitch or spacing between successive printed products corresponds to the predeterminate pitch or spacing.

Title: Coherent demodulation method for a digitally modulated signal having a continuous phase and a constant envelope
Inventor: GELIN BENOIT
IPC: H04L27/233
Filed: 1989-06-23
Granted: 1992-10-06
Abstract: ABSTRACT: "Coherent demodulation method for a digitally modulated signal having a continuous phase and a constant envelope"     The method ensures the coherent demodulation by digitally processing a continuous-phase modulated signal (for instance, of the GMSK type). The received signal is transposed in the baseband, converted into a digital signal and transferred to a signal processor. Each transmitted data packet comprises a known preamble sequence of N bits allowing of approximately estimating the frame-synchronization and the bit-synchronization and also the initial phase and the residual frequency offset. The progressive refinement of the said estimation is obtained by means of two interleaved digital loops: a slow loop for detecting the bit-synchronization and a fast loop effecting intermediate decisions over additional blocks of bits for the estimation of the initial phase and the residual frequency offset.

Abstract: Pregelatinized high amylose starches are useful in processing cast jelly gum confectionaries. The starch has an amylose content of at least 40% and it may be used alone or in combination with a converted starch.  The starch is pregelatinized by spray-drying using a novel continuous coupled jet-cooking/spray-drying process or simultaneous atomization/spray-drying process or by drum-drying after fully dispersing the starch.  The confectionary can be cooked at a lower temperature than was possible using prior art starches and still provide confectionaries with desirable characteristics.
