Patent CA-2038645-A1 (CA)
IPC: H04B7/26
Filed: 1991-03-19
Abstract: ABSTRACT OF THE DISCLOSURE     Disclosed herein is a control device which is suitable for use in a radio communication apparatus employed in a radio communication system using a TDMA method.  A timer circuit for circulating a counted value in a period corresponding to a period of time re-quired to transmit a TDMA frame supplies the counted value to a strobe signal generating circuit.  The strobe signal generating circuit supplies a strobe sig-nal to a radio unit of the radio communication appara-tus when a preset value coincides with the counted value of the timer circuit.  Thus, since the strobe signal is generated without the intervention by a con-trol circuit made up of a CPU or the like, it can be outputted in strict timing.

Abstract: An apparatus for the timed feeding of fish into fish pro-cessing machines  serves to supply such fish into a con-veyor pushing them along in a direction transversal to their longitudinal axis and being provided with receiv-ing troughs or entrainers.  In order to be able to ob-tain the high performance non-mechanical feeding re-quired in view of the high yield of modern processing machines while restricting as much as possible the physi-cal stress on the staff responsible therefor, or to in-crease the non-mechanical performance without increasing the stress, a feeding apparatus is provided above the conveyor of the processing machine which apparatus in-cludes a rotary entraining table or spider driven in synchronism with the conveyor.  The entraining elements rotate about a fixed supporting surface and are attached tangentially to a hub so that the fish supplied to the thus formed chambers are charged with a pushing force or component effective in an inward or outward direction depending on the direction of rotation, which component effects a precise positioning of the fish by engagement of the mouth portion with a stop  just before the trans-mitting to the conveyor occurs.

Abstract: ABSTRACT OF THE DISCLOSURE     A process for the removal of nitrogen oxides from exhaust gases while recovering nitric acid is described.  When this is done, the exhaust gas is charged with the required quantity of hydrogen peroxide that has been transformed to the gaseous phase and converts the gas mixture to hydrogen nitrate on a catalyst, which is then tapped off for further use or else converted to nitric acid in the manner known per se either by condensation or by washing with water.  The process makes it possible to remove NOx at low concentrations of < 2000 ppm, with a degree of efficiency above 90%.

Title: Method of processing printing products arriving in an imbricated formation
Inventor: HONEGGER WERNER
IPC: B65H29/66
Filed: 1991-07-02
Abstract: ABSTRACT OF THE DISCLOSURE     Printing products, arriving in an imbricated formation, have a certain formation length and approximately equal imbrication spacings.   An imbrication-like formation is formed by pushing together the printing products and, at the same time, shortening the imbrication spacing.   The imbrication-like formation is rolled up, together with a wrapping element, into a roll-shaped bundle.  An end user then unrolls the bundle and pushes the imbrication-like formation together to form a vertical stack.   For this purpose,  the  length  of  the  imbrication-like  formation length is chosen such that the same person can grasp, with his hands, the ends of the formation at the same time.          Individual printing products may then be removed from the stack.

Title: Compartmentalized refuse container
Inventor: CHANDLER JOHN W
IPC: B65D6/40
Filed: 1991-07-22
Abstract: COMPARTMENTALIZED REFUSE CONTAINER                        ABSTRACT   The container comprises two or more tube-like storage modules  that  are  stacked  on  top of  one  another  and interconnected by a plate-like lid which is removably interposed  in the  joint between  the modules  and has male/female joint-forming attachment grooves on the upper and lower sides thereof, which mate with in-turned out-turned flanges on the lower and upper rims of the modules, respectively, to form a joint in which the modules are releasably interlocked against relative movement in the lateral directions thereof.  The modules have open-ended bins therewithin, and additional openings in the sides thereof through which a pair of panels are removably insertable to form false bottoms for the bins, or in the alternative,  to open the bottoms of the bins for the unloading operation, when the panels are removed from the bins.   Further additional openings in the sides of the modules,  above the panel receiving openings,  serve as entry ports through which refuse can be loaded in the respective bins of the modules,  so that two types of refuse can be loaded in the respective bins, with the bottom  forming  panel  of  the  relatively upper module segregating one bin from the other.   Later,  when the container is to be unloaded the two types can be separ-ately unloaded through the top and bottom openings of the stack of modules, and/or through the respective top and/or bottom openings of the respective modules when they have been separated from the lid by relatively lifting one module away from the other.  Commonly, the upper module is also equipped with a lid of similar nature, and when there are more than two modules in the stack, this lid may serve in turn as a coupler for the pair of modules above and below it, just as the first mentioned lid served as such.

Title: Urethane acrylate surfaced laminate
Inventor: DION ANDREW N
IPC: B32B7/02
Filed: 1991-09-04
Abstract: ABSTRACT OF THE INVENTION A decorative laminate,  and a process for making same, featuring a protective outer layer which provides superior scratch, wear,  and chemical resistance,  and which is tightly bound to the layer immediately beneath so as to reduce the tendency of the protective layer to delaminate  from  the  layer  immediately  below.    The laminate uses radiation-polymerizable urethane acrylate coated surfaces and utilizes a photoinitiator, a thermal catalyst and a coupling agent.  The coupling agent serves to more securely bond the protective layer to the surface onto which the protective surface  is  coated.    The protective  layer  is  created  by  first  applying  the reactants to finish paper,  then partly curing by UV radiation.  The partly cured material is then applied to the  surface  to  be  protected,  and  the  laminate  is consolidated and the outer layer is completely cured by thermopressing.

Title: Melting metal particles and dispersing gas with vaned impeller
Inventor: GILBERT RONALD E
IPC: F27D27/00
Filed: 1991-11-08
Abstract: MELTING METAL PARTICLES AND DISPERSING GAS WITH VANED IMPELLER                           Abstract Metal particles are melted by mixing them with molten metal contained in a bath.  A shaft-supported, rotatable impeller is immersed into the molten metal and rotated so as to establish a vortex-like flow of molten metal.  Metal particles are deposited onto the surface of the molten metal in the vicinity of the rotating impeller.   The particles are submerged substantially immediately after being deposited onto the surface of the molten metal.   The impeller includes a thin rectangular prism having sharp-edged corners and vanes that extend upwardly from the prism. The impeller also can be used to disperse gas into the molten metal by pumping the gas through a bore extending the length of the shaft and out of the impeller along the lower surface of the impeller. The gas is sheared into finely divided bubbles as it rises along the sides of the impeller.
