Title: Cathode ray tube display system with minimized distortion from aliasing
Inventor: EDELSON STEVEN D
IPC: G09G5/02
Filed: 1983-02-18
Abstract: In a cathode ray tube display system in which objects to be displayed are represented by digital signals, a technique is employed to reduce distortion caused by aliasing. The objects to be displayed are represented in a memory (53) by transition specifications which represent the object to be displayed by defining the character of the edges of the object to be displayed. From the transition specifications, a video signal is generated and applied to the cathode ray tube display device to display the object represented by the stored transition specifications. The circuitry (21) generating the video signal causes the video to change in steps across the width of a transition from the brightness prior to the edge with the width of the transition varying in accordance with the slope that the edge makes with the raster scan line.

Title: Dispenser for the metered delivery of pasty products
Inventor: VON SCHUCKMANN ALFRED
IPC: B65D83/00
Filed: 1989-02-01
Abstract: A dispenser for pasty products such as toothpaste is described. The dispenser (1) has a discharge tube (7) with an outlet (10) and a closure member (11). During a dispensing cycle, the closure member and the tube are moved away from each other via a trigger (6) operated rocker element (8) mounted to the pumping diaphragm (5) via a ball and socket type joint (12). Upon release of the trigger the dispenser automatically returns to the closed position. This configuration allows for a toothbrush to be placed directly adjacent the discharge opening (10) without having to worry about it getting in the way of the closure member when the closure member opens. This provides for a more user-friendly, quickly activated dispenser which minimizes toothpaste wastage. An insert (9) further provides for producing a stripped product.

Title: Membrane packing
Inventor: RIDGEWAY LOUIS HERBERT
IPC: B65D81/07
Filed: 1989-02-21
Abstract: An improved packing device which holds an article being shipped between membranes. The membranes provide shock adsorption through their own resiliency and by allowing motion when forces in excess of the frictional limit are applied. A pair of rigid frames (3) and (9) having central openings covered by an attached pliable material (7), form spacers which are forced in intimate contact with a fragile article (6) within its shipping container (2) to absorb shocks, flexion and torsion of the container due to shipping and handling loads. The spacers can be a box-like structure with at least one open face covered with a flexible membrane. The contour of the other faces of the structure are shaped and dimensioned to match the internal geometry of the container. In some applications, the spacer structure is a wedge that fits in one corner of the container. Two to four such wedges are typically used to support the object. The framed membranes offer a versatile substitute for a variety of common packing inserts.
