Patent CA-1140397-A (CA)
Inventor: BLOECK SIEGFRIED
IPC: B21D51/38
Filed: 1979-06-05
Granted: 1983-02-01
Abstract: A B S T R A C T     The process allows the manufacture of lacquered aluminum or tin-plate rings which have the inner edge bent over outwards and are suitable for the closures on cans for foodstuffs. A ring blank made of lacquered sheet is pre-shaped by deep drawing to form the curvature needed for bending over the inner cut edge. The final shaping of the pre-shaped blank into a ring for a can lid takes place, after stamping out the opening, by stretching and bending over the cut edge. When a tear-back membrane is sealed on to the bent-over edge, the ring is suitable as an easy-ly opened closure for cans of foodstuffs.

Abstract: ABSTRACT OF THE DISCLOSURE                The present invention provides a grill which is comprised of a vessel open at the top, a gridiron which is placed into the vessel for supporting the foods to be grilled and to which first vessel an upper vessel or lid is fastened by means of hinges.  The upper vessel is approximately the same size as the first vessel and being open at the bottom and the hinge position is at, or close to, the edges of the vessels so that the vessels can be brought against each other or close to this position and so that they can be opened to an open posi-tion or allowed to remain in a position that is open to the desired extent.  The invention is characterized in that an electric heating resistance is placed in the upper vessel and is connected to the above hinge position so that in its heating position, the resistance can be made substantially parallel with the edges of the upper vessel and that it can be pivoted from this position over its hinge position to a partly open position underneath the edges of the upper vessel so that it is then possible to place a reflector plate above the resis-tance.  The reflector plate remains above the resistance in the upper vessel when the resistance has been pivoted to its heating position into the upper vessel and it can also be easily removed by pivoting the resistance to the opened position.

Abstract: ABSTRACT:          An integrated circuit Read-Only Memory (ROM) with improved speed of operation is disclosed as generally representative of simi-larly improved logic arrays.  The ROM includes parallel rows of con-ductors oriented normal to parallel doped regions which form column conductors.  The ROM is implemented with field-effect transistors and comprises two decoder fields and a data field.  The transistors of the decoder fields serve to define open circuits between adjacent column conductors in accordance with binary input signals applied to the decoder fields.  In the illustrative ROM, a first column con-ductor is connected to a return terminal of a power supply and a second column conductor is connected to a "pull-up" circuit.  The il-lustrative circuit provides for the connection of power supply return connections to both ends of the one column conductor and provides for the connection of pull-up circuits to both ends of the second column conductor.  The row conductors are connected to gates of transistors in both the data and the decoder fields and a low impedance path from the pull-up circuits to the power supply return is established in response to signals on the row conductors.

Abstract: PRESSURE-DEHAND BREATHING APPARATUS                WITH AUTOMATIC AIR SHUT-OFF               Abstract of the Disclosure A face mask is connected to a source of breathing fluid through a pressure-demand regulator and a supply line. The regulator admits breathing fluid to the mask on demand and main-tains a positive pressure within the mask at all times to prevent inflow from the surrounding atmosphere. The regulator has a flow capacity, considerably greater than that normally required, even when gasping or breathing heavily. An automatic shut-off device in the supply line upstream of the regulator permits the peak flow of a predetermined breathing requirement but is responsive to abnormal flow conditions, an for example where the mask is removed from the wearer, to close the supply line and thereby prevent wasting of the air breathing fluid supply.           The apparatus can be manually reset to normal operation and will reset itself after the mask is repositioned on the wearer.

Abstract: ABSTRACT         An impeller for a variable pitch axial flow fan in which the actuator is arranged to rotate the blades towards their maximum pitch angle, and the inherent blade turning moment of the blades when the impeller is rotating provides the restoring force for moving the blades towards their minimum pitch angle. The impeller avoids the need for blade counterweights and a heavy return spring, and so enables a relatively smaller and lighter hub to be used compared with those employed in equivalent impellers with counterweighted blades.

Abstract: ABSTRACT           A composition of matter comprising the reaction product of a bitumen and a fatty oil, e.g., asphalt and castor oil, and a process of preparation therefor.  The reaction product is combined with a polyhydroxy compound and a polyisocyanate, and allowed to react in the pre-sence of a blowing agent, such as water, to form a foamed polymeric  material.  A particularly suitable blowing agent comprises a mixture of dibutylphthalate and ethanol, the use of which obviates the necessity for a surfactant in the reaction mix.  Preferred foamed polymeric products can be cured to materials which are strong and tough but which even after they are fully cured are soluble in molten asphalt. Such foamed polymeric products are particularly suitable for use as a construction material for shipping pallets for roofing tar.

Abstract: ABSTRACT OF THE DISCLOSURE        An E. coil strain producing metabolically active but non-reproductive, anucleated live cells, which contain the K99 surface antigen, is obtained by transferring the K99 plasmid from a K99+ entero pathogenic E. coli strain into an E. coli strain which generates progeny of cells that lack the ability to multiply.  From the resulting E. coli strain a "live" vaccine is prepared.  Separation and purification of the anucleated live cells from growing cells is the basis for the "live" and chemically and/or physically unmodified vaccine.  The vaccine induces the production of antibodies against growing and infective enteropathogenic K99+ E. coli in cattle and is, thus effective against coliform enteritis.

Abstract: ABSTRACT:       For the backprojection of the convoluted measurement signals in a cartesian coordinate system in a computer tomography device, it is necessary to recalculate the weighting factors for each posi-tion of the source in order to determine the contribution of a convoluted measurement signal to the attenuation value associated with a given element of the output image matrix. The invention relates to the use of a matrix of the memory the origin central coordinate of  said matrix coinciding with the centre of rotation of the X-ray source about the object section. The weighting factors are also stored in a polar organised memory. The angular component of the address of the weighting factors is incremented with a rotational increment in the corresponding position of the X-ray source, so that for each group of measurement values, the same weighting factors can be used. The invention enables all the weight-ing factors to be stored in a memory of limited capacity. This is a time consuming and hence expensive form of reconstruction.
