Patent MX-9710018-A (MX)
Title: Clinch.-type fastener member.
Inventor: DONOVAN STEVEN PATRICK
IPC: F16B39/282
Filed: 1997-12-10
Abstract: A novel clinch-type fastener member is engaged through first and second workpieces to form a mechanically locked joint which is highly resistant to vibrational loosening. The fastener member has a first portion and a second portion defined by a shank portion which extends therefrom. The first portion has a protuberance, formed from a ring, thereon which extends outwardly therefrom. The shank portion has a projection, formed from a ring, spaced a predetermined distance from the first portion to define a retaining groove. To engage the fastener member with the workpieces, the fastener member is rotated into engagement therewith. The protuberance on the first portion engages a top surface of the first workpiece and rotational and compressive forces are applied to the fastener member thereby causing the protuberance to deform the first workpiece material to cause the maerial to flow into the retaining groove provided on the fastener member. The projection on the shank portion generally contacts the first workpiece such that when the deformed material flows into the retaining groove, the deformed material is captured between the projection and the first portion.

Title: Method and apparatus for maintaining channel priority in a multiple wireless communication system environment.
Inventor: RAFFEL MICHAEL ALLEN
IPC: H04W16/16
Filed: 1997-06-11
Abstract: A method and system are disclosed for a transmitter to maintain priority on a communication channel in a multiple wireless communication system environments. An exemplary method for maintaining priority includes transmitting a priority signal to maintain priority for the transmitter on the communication channel. The priority signal may be pseudo-random noise (PRN) signals. In one embodiment, the PRN signals are transmitted in response to activity sensed on the communication channel, one cause of which may be a contending transmitter transmitting on the communication channel. In this embodiment the step of transmitting is for a predetermined duration and causes the contending transmitter to stop transmitting on the communications channel. In an alternate embodiment , the transmission of the PRN signals is periodic and occurs sufficiently often to cause the contending transmitter to abstain from ever transmitting on the communication channel.

Patent MY-8700056-A (MY)
Title: Apparatus and method for detecting the passage of coins
Inventor: DEAN ROBERT
IPC: G01V8/14
Filed: 1987-12-30
Abstract: The illustrated embodiment is an apparatus for detecting the passage of a coin down a coin passageway 14 of oblong cross-section where the width of the passageway is so great that the smallest coin can pass a single sensor in the passageway without activating the sensor. The apparatus comprises a light source 25 and a light detector 26 located in one wall of the passageway, spaced from one another across the width of the passageway and from the sides of the passageway. A prism 29 of transparent material is located in the wall of the passageway opposite the light source and detector and has two 45 DEG  reflecting surfaces 32 and 33. The first reflecting surface 32 reflects a beam of light from the source 25 towards the second reflecting surface 33, the second reflecting surface 33 reflecting the light toward the sensor 26. Thus the beam of light from the source 25 to the sensor 26 crosses the passageway 14 at two positions spaced from one another across the passageway. Even the smallest coin passing down the passageway breaks the beam at one of the crossing positions.

Patent NL-8900757-A (NL)
Inventor: ILENDA CASMIR STANISLAUS
IPC: C08L23/02
Filed: 1989-03-28
Abstract: A novel graft copolymer capable of imparting to a polyolefin when blended therewith a good balance of tensile modulus, sag resistance and melt viscosity, is a polyolefin trunk having a, preferably relatively high weight-average molecular weight, methacrylate polymer chain grafted thereto. The graft copolymer is formed by dissolving a non-polar polyolefin in an inert hydrocarbon solvent, and, while stirring the mixture, adding methacrylate monomer together with initiator to produce a constant, low concentration of radicals, and covalently graft a polymer chain, preferably of relatively high molecular weight, to the polyolefin backbone. The graft copolymer can be separated from the solvent, by volatilizing the solvent, for example in a devolatilizing extruder, and pelletised or extruded or otherwise shaped into a desired shape such as a sheet, tube or the like. This graft copolymer can be blended with a polyolefin matrix to improve its physical properties in the melt, upon cooling, and in the solid state, and is useful in cast and oriented films, solid extruded rod and profile, foamed rod, profile and sheet and blown bottles. The graft copolymer can also be used to improve compatibility between polymers in a wide range of polymer blends.
