Patent CA-2292118-A1 (CA)
Inventor: LANDOLT MARKUS
IPC: B26D1/02
Filed: 1999-12-13
Abstract: The cutting arrangement for a band-shaped material to be cut, especially photographic copy material, includes a stationary cutting edge (5) and a pressure member (12) moveably guided along the cutting edge as well as drive means (7), (10), (11) for moving the pressure member along the cutting edge. The pressure member (12) on its path along the cutting edge (5) forces the material to be cut (P) which rests on the cutting edge against the cutting edge in a pressure region which is short compared to the length of the cutting edge (5) and thereby severs the material to be cut by compression. The required force is thereby limited to the movement of the pressure member (12) along the cutting edge (5) and is significantly smaller than in conventional cutting arrangements of this type.

Patent CA-2296410-A1 (CA)
Inventor: ERSSON YNGVE ANDERS
IPC: G09F13/20
Filed: 1998-07-13
Abstract: The invention relates to a device and a method for supplying informatics to pilots, especially in poor visibility, about, for instance, the borders of a runway (1). Along the long sides of the runway and at its beginning and end, signal means (2, 5) are arranged, which are translucent to e.g. UV radiation and which comprise a fluorescent material which converts the radiation penetrated by illumination into visible light. In the daytime, the UV radiation originates from sunlight. The converted light will then reinforce the usual light from the signal means, which originates from the sun's illumination thereof with visible light. As a result, in will be much easier to observe the signal means especially against the light. It is further suggested according to the invention that at night the signal means are illuminated by UV searchlights (34, 35). By a great number of signal means being illuminated simultaneously by a small number of searchlights, a great amount of electric equipment and installation work can be avoided. It is suggested that the signal means be made as flat screens in the form of square or rectangular pieces of plastic sheeting expanded between poles.

Abstract: A Built-In Self Test (BIST) system 100 is provided for testing data transmission health at the payload level of a satellite communication system 400 and within a communications satellite 130 of the system 400. The BIST system 100 includes a demodulator 136 having a BIST pattern generator injecting a BIST pattern into the data stream of a communications satellite 130.

Additionally, the BIST pattern may be passed from an input crossbar switch 138, an output crossbar switch 180, a data switch 160 within a routing processor 140, or a processing module 165 within a routing processor 140 to the on-board computer 142 for the BIST comparison. Additionally, the BIST pattern may be crosslinked between satellites in the satellite communication system 400 or may be looped back from the output crossbar switch 144 to the input crossbar switch 138 of the satellite 130. The BIST pattern may be supplied to the BIST generator by a data generator circuit such as a ROM, a memory within the on-board computer 142, or a ground command circuit.

Title: Child-resistant squeeze-and-turn closure, package and method of manufacturing
Inventor: ROBINSON PHILIP J
IPC: B65D50/04
Filed: 2000-09-29
Abstract: A child-resistant closure that includes a base wall, a peripheral outer wall extending from the base wall, and an inner wall spaced radially inwardly from the outer wall and having an internal thread for securement to a container finish. The outer wall of the closure has diametrically opposed circumferential gaps, and the inner wall extends axially in radial alignment with the gaps in the outer wall for circumferential abutment with lugs on a shoulder of a container. The inner wall is flexible inwardly for clearing the container lugs and permitting removal of the closure from the container finish. The outer wall thus protects the force application area of the inner wall by reason of the fact that such force application area is recessed inwardly with respect to the circumference of the outer wall. The closure resists application of planer force to the removal area of the inner wall, such as by a child biting the closure.  Furthermore, the modified dual-wall construction of the present invention may be constructed in small sizes suitable for use in conjunction with containers having small finish diameters.

IPC: E02B8/06
Filed: 1999-04-27
Abstract: A spillway (10) for use in a sloped embankment (12) which defines a top (1it) and a toe (16). The spillway (10) is adapted to dissipate the kinetic energy of water flowing downwardly from the top of the embankment (14) to the toe (16) thereof in a primary flow direction (PF). The spillway (10) comprises a plurality of building blocks (18, 20) arranged in rows which are stacked upon each other in a single-like overlap such that the building blocks (18, ) of each row are offset relative to the building blocks (18, 20) of each adjacent row and a series of steps are defined thereby. The building blocks (18, 20) are sized and configured such that water cascading down the steps defined thereby is caused to flow in three dimensions so as to impart velocity components to the falling water that act at generally right angles relative to the primary flow direction (PF) and generate turbulence which dissipates the kinetic energy of the water.
