Patent CA-2135213-C (CA)
Inventor: HOFFMANN EDUARD
IPC: B41N1/08
Filed: 1994-11-07
Granted: 1998-11-24
Abstract: A sleeve-shaped printing sleeve for a form cylinder of a printing machine is fabricated from a blank of metallic material by cutting the blank to a width corresponding to the form cylinder and to an intermediate length which exceeds the circumference of the intended printing form cylinder. Additionally, the blank is provided with aligning indicia in the regions between each edge of the intermediate-length blank and the corresponding edge to be defined by cutting. Thus, these regions lie outside of the printing area. The blank is bent circularly, held in exact register in a bending/welding device, and cut to the length required for the intended form cylinder by laser beam cutters. As a result of this cutting operation, two waste pieces are produced. The waste pieces are removed and the now defined plate edges forming the beginning and end of the printing form are positioned opposite one another without overlap and welded together, preferably by a laser.

Abstract: A labelling system (10) dispenses a web (36) of label material having a coating  (43)  of non-tacky activatable adhesive, subsequently activates the adhesive, feeds the web to the next location,  where the web  (36)  is cut, preferably using a pair of  laser beams  (52a,  52b)  to produce labels (80) therefrom, and then, at a further point of the system, applies the labels to respective packages (18).  In another embodiment (90), a carrier sheet (104) is separated from an adhered web (102) whereupon the web (102) is then cut using a laser beam (52) to form labels (112) and a waste matrix  (114).   The labels  (112)  are then rejoined to the carrier sheet (104). The  invention  provides  advance  in  the  art  by eliminating the need for a carrier sheet in the production and application of labels to packages, and eliminates the need for custom manufactured dies for cutting labels.

Abstract: A method of continuously manufacturing chewing gum with improved flavor perception comprises the steps of adding at least an elastomer and filler into a high-efficiency continuous mixer, and mixing the elastomer and filler together in the continuous mixer; adding a least one ingredient selected from the group consisting of fats, oils, waxes and elastomer plasticizers into the continuous mixer, and mixing said ingredient with the elastomer and filler in the continuous mixer; and adding at least one sweetener and at least one flavor into the continuous mixer, and mixing said sweetener and flavor with the remaining ingredients to form a chewing gum composition. These steps are performed using a single high-efficiency continuous mixer and wherein the flavor is added at a level lower than that used to make the same chewing gum composition in a batch mixer but the flavor intensity in the chewing gum product is comparable to that of said same chewing gum composition made in a batch mixer.

Granted: 1998-11-03
Abstract: The object of the invention is to eliminate by using a multi-layered film initializing field in magneto-optical recording capable of direct overwriting, and to decrease the restrictions on the compositions of materials for media. The medium consists of two exchange-coupled RETM amorphous layers (a memory layer a reference layer) whose Curie temperatures arealmost the same and only one of which is RE-rich without a compensation temperature, the two layers being laminated directly or indirectly with an intermediate layer that allows exchange-coupling to be interposed. Before recording is carried out, the reference layer is magnetized in one direction. Pulses of energy are emitted from the memory layer side so that the temperature of the reference layer remains below its Curie temperature when one of the bit data is recorded but reaches its Curie temperature when the other of the bit data is recorded.

Abstract: A method for producing a validation mark on security pa-per includes (10) printing the mark on the paper using an ink that has the same color as the paper but which has more uni-form directional reflectance than the sheet of paper. That is, the dried ink is a more uniform dif-fuse reflector than is the paper. When the mark is illuminated by a light source (14), as in Fig.6, located on one side of the mark, the mark appears lighter than the paper around it when viewed from the same side as the light source, as in Fig.5; but the mark appears darker than the paper around it, as in Fig.4, when viewed from the side opposite the light source, as in Fig.3. examplary is given.

Title: Latch with adjustable backset
Inventor: ELLIS PHILIP C
IPC: E05B63/06
Filed: 1996-09-17
Granted: 1999-02-23
Abstract: The adjustable latch bolt of this invention features a novel cam actuating assembly which permits election of one of two door knob spindle backsets which are in standard usage.   The cam assembly is comprised of two half hubs, each having one arm so that one half hub operates the drawbar in one direction of rotation and the other in the opposite direction of rotation.  The half hubs are formed so that a portion of one half hub nests in a depression in the other in such a way that the two half hubs can rotate relative to each other.  When the hubs are set to one of two backsets and are in a position to actuate the drawbar, non-circular openings passing through the axis of rotation of the two hubs are aligned so that a complementary shaped spindle can pass through both hubs and engage them for rotation.  With the spindle in place the two half hubs are prevented from rotation relative to each other.  In this condition, the distance between the two arms is greater than the distance between detents on the drawbar and the cam assembly cannot be moved from one backset position to another.  With the spindle removed the two half hubs can be rotated relative to each other so that the distance between the arms is less than the distance between the detents on the drawbar and the cam assembly is able to pass between the detents from one backset position to another.

Abstract: In accordance with the present invention, a general antenna system is disclosed suitable for applications in which an RFID Tag passes by an Interrogator. We then disclose a specific antenna design that uses a single planar antenna fortransmit and a multi-element planar antenna array for receive. The multi-elementplanar antenna array is spaced such that each of the planar elements is four inches apart, center-to-center, thus defining a narrow 30° receive beamwidth in the horizontal plane. The vertical receive bandwidth is much greater than 30°, facilitating the Interrogator receiving signals at a variety of elevations. Furthermore, a multi-way microstrip combiner is used to sum the signals received from each of the planar antenna.  To block interference from the transmit antenna and to improve receivesensitivity, this multi-way microstrip combiner is shielded using, in one embodiment, copper tape along its edges. In a specific embodiment, a four element receive antenna design is disclosed.

Title: Process for compacting and sintering a powdered metal preform
Inventor: HUBBARD THEODORE RUSSELL
IPC: B30B11/00
Filed: 1996-04-11
Granted: 2002-09-03
Abstract: A process is disclosed for forming a pressed metal part in which a preform (122) is inserted into a pressed metal mold. The mold is then filled with powdered metal. The powdered metal and preform are compacted to create a compacted metal part wherein the preform defines an adjacent volume next to the compacted metal part. The compacted metal part is ejected from the mold and sintered to create a sintered metal part. The preform is removed by the sintering step in such a way that the adjacent volume becomes a void region.  The preform can be formed of copper so that, upon sintering, the preform is removed from the sintered metal part through infiltration. Alternatively, the preform can be formed of zinc so that, upon sintering, the preform is vaporized and thereby removed from the sintered metal part. The void region created by the removal of the preform can be an undercut, a taper, an annular groove, a thread or an internal cavity. In this way, the present invention eliminates the need for machining such surfaces as has been necessary using previous compaction methods.
