Title: Method of and a mold for injection molding of articles made of a thermoplastic material and the walls of which enclose a hollow space
Inventor: ECKARDT HELMUT
IPC: B29C45/17
Filed: 1993-10-01
Abstract: Proposed is a process for injection molding of products (1) made of thermoplastic material, whose walls (2) enclose a hollow space (3), wherein the molten plastic is injected in a predetermined amount into the cavity or molding nest (6) of a mold (5), during and/or upon which a fluid pressure medium (gas) is applied so that with the formation of the hollow space the molten plastic is distributed along and set against the walls of the cavity or molding nest. The pressure medium (gas) is fed into the cavity or molding nest (6) and into the molten plastic at first essentially only in the direction of flow of the molten plastic and in a quantity and/or at a pressure that causes a void (8) to form within the molten plastic, terminating at a distance from the end of the flow path. Then, with a time lag, more pressure medium (gas) at a higher or increased level of pressure is fed into the cavity and the molten plastic from the end of the flow path for the molten plastic and essentially counter to the direction of flow of the molten plastic, forming a second void (11) which joins with the already existing void (8).

Patent CA-2157413-A1 (CA)
Inventor: CHAMBERS JOSEPH ANDRE MICHAEL
IPC: F02B23/08
Filed: 1995-09-08
Abstract: In a conventional internal combustion engine the cylinder within which the piston moves is more or less cylindrical throughout its length, the top of the cylinder being designed to house the intake and exhaust values and the spark plug. In this invention the top of the cylinder, in which the combustion is first ignited, is shaped as a paraboloid of revolution. A parabola is a conic section of eccentricity 1. In Cartesian coordinates a parabola can be represented by the equation:     y2=4ax If a parabola is rotated around its axis, the resulting surface is called a paraboloid of revolution. The reflective mirror in an automobile headlight for example, is a paraboloid of revolution. As such it exploits the focusing property of the parabola. In the headlight, the bulb which radiates the light, is placed at the focus of the paraboloid of revolution. A ray of light starting at the focus, hits the surface of the mirror and is reflected along a line parallel to the axis.     In this invention, the same principle is exploited to focus the explosive energy of the combustion along lines parallel to the motion of the piston. In this fashion, the piston and cylinder more efficiently convert the energy of combustion into mechanical energy.

Patent CA-2165556-A1 (CA)
Title: Child-birth assisting system
Inventor: HAHN SOONKAP
IPC: A61B5/00
Filed: 1994-06-28
Abstract: The childbirth-assisting device uses an automatically synchronized expandable pneumatic girdle to externally augment the secondary force of labor. The pneumatic girdle is fitted around the abdomen of the woman and the girdle is inflated to create a downward pressure on the abdomen when a contraction occurs. The synchronization of the girdle's inflation and the contractions is provided by an electronic controller which receives a signal from an intra-uterine monitor indicating a contraction and causes the girdle to inflate at a certain rate until a preset intra-uterine pressure is attained. Once the intra-uterine pressure reaches the pre-set pressure, the girdle pressure is maintained until the offset of the contraction is detected, at which time the girdle is deflated.
Patent CA-2166545-A1 (CA)
Inventor: PARKE IAN
IPC: G06T9/00
Filed: 1994-07-29
Abstract: Telescopic predictive coding of video frames reduces the number of pixels in a reference frame which are required to be processed. However, given that offsets for adjacent blocks may differ, it is difficult to parallel process the reference data for real-time coding. After first-frame motion vectors have been calculated, a region of the reference pixels is read which is large enough to accommodate the direct calculation of motion vector for the second frame, thus allowing pixel values to be processed in parallel. However, although all of the read pixels are made available to each processor, the processors only latch the values which are actually required for the particular motion vector being calculated. This is achieved by supplying an enabling signal to the processors, which is determined by processing the first-frame motion vectors.

Abstract: A bullet trap with a passageway defined between flat upper and lower boundary walls extending convergingly, at opposite angles of inclination of between 0 DEG  and about 15 DEG  to the horizontal, from an entrance opening to an exit opening or throat, and a deceleration chamber having a generally spirally curved circumferential boundary wall and provided in its upper region with an inlet opening and in its lower region with a discharge opening leading to a collecting vessel. The circumferential boundary wall of the chamber is constituted by two oppositely concave channel-shaped members the respective upper end regions of which are spaced from each other to define the inlet opening, and the respective lower end regions of which are spaced from each other to define the discharge opening. The chamber communicates at its upper region with the passageway substantially tangentially of the chamber via the directly adjacent inlet opening and throat, and a liquid lubricating fluid can be directed into the chamber from the collecting vessel either in a forced flow mode (pump-activated) through the inlet opening or in a passive mode (bullet-activated) through the discharge opening. For the special purpose of enabling a previously fired firearm to be checked for whether a bullet remains in the firing chamber of the firearm, the trap may have the same basic construction but without the liquid lubricating fluid feature.
