Title: Optical compact disc storage and loading cassette
Inventor: NEWELL TERENCE JOHN
IPC: G11B23/03
Filed: 1993-07-21
Abstract: A CD storage and loading cassette is made from a limited number of components most or all of which are formed by moulding. The moulded components are a tray (2), a slide cover (4), a magnetically permeable puck (8) and a lid (10), in addition to which there may be used a coil spring (6). The cassette is compatible with existing industry standard CD Readers, and its novel design permits the manufacturing and assembly costs to be substantially reduced over the corresponding costs for conventional cassettes. The cassette may be made with planar top and bottom faces to receive the maximum amount of printed information relevant to the data stored on the CD contained in the cassette.

Title: Improved gas phase process for forming polyketones
Inventor: HANNA PAUL K
IPC: C08G67/00
Filed: 1993-06-15
Abstract: Polyketones can be formed in enhanced yield by conducting the polymerization of the carbon monoxide and olefin mon-omers used to form the polyketone in a gas phase polymerization process in the presence of a catalyst support which is substan-tially saturated with an amount of a liquid, non-polymerizable diluent, for example, an organic diluent, which is effective in in-creasing the amount of polyketone formed over that which would be formed in the substantial absence of the diluent. Preferably, the catalyst is supported on a high surface area polyketone support (e.g., a carbon monoxide-ethylene high surface area support). Hydrogen gas can be used to reduce the molecular weight and increase the bulk density and thermal stability of the polyketone product.

Title: Process and apparatus for producing an environmentally acceptable abrasive product from hazardous wastes
Inventor: BALCAR GERALD P
IPC: C03C14/00
Filed: 1994-01-25
Abstract: A method and apparatus of reclaiming hazardous inorganic wastes to produce an environmentally benign abrasive for use in loose grain processes, as a coated or bonded abrasive, or as a polishing grain. A tough and useful abrasive, with an MOH hardness of 7 to 8, is manufactured from emission control dusts of aluminum industry or sludges from other industries, and may include small amounts of lead and cadmium oxides as toughening agents. The abrasive particles are sized by air sifting or by water sedimentation separating methods. The process for the manufacture of abrasive material comprises the steps of removing soluble salts from a waste stream by hot water extraction; using a computer matrix to group the waste stream into different batches for mixing with other glass-making materials to form a batch mixture; oxidizing the organic compounds contained in the batched mixture; melting the batch mixture to form a glasseous substance; and fritting the glasseous substance to form the abrasive. The process preferably uses a glass melter that will oxidize organics; a scrubber to recapture vaporized heavy metal oxides and particles of the glass-making materials; and an oxygen injection system to ensure thorough burning of organics. Certain sodium compounds may be added to reduce the melting point of the batch mixture.

The predetermined number of optical input devices is nogreater than the predetermined number of electric inputs to the circuit cell. Also after the electronic circuit design is selected, a predetermined number of optical output devices are located on the circuit cell design in a second prearranged orientation. The predetermined number of optical output devices is no greater than the predetermined number of electric outputs to the circuit cell. At least a topmost layer of metalization is selected for electrically coupling each optical input device to a distinct one of the electric inputs of the circuit cell and for electrically coupling each optical output device to a distinct one of the electric outputs of the circuit cell.

Patent CA-2170936-A1 (CA)
Title: Flushable midstream urine collector
Inventor: CAWOOD CHARLES DAVID
IPC: A61B10/00
Filed: 1996-03-04
Abstract: A flushable midstream urine collector which is discardable, dissolvable, and flushable in the water of a common flush toilet without obstructing or damaging the water discharge lines of the waste water system is disclosed.  The collector includes an open-ended tubular body which defines a flow passage and a cup member which is mounted in the flow passage.  The cup member by-passes the initial and terminal portions of the urine stream when a patient voids into the collector, but the cup member collects a midstream sample which may be easily transferred from the cup member to a collection tube.  The primary structural components of the tubular body and cup member are formed from a water-soluble material which will dissolve or disperse when disposed in the water of a toilet bowl.  However, thin protective layers of water-insoluble material line the interior of the tubular body and cup member for preventing urine passing through the device from initiating premature dissolution of the primary components of the collector.  When discarded in the water of a toilet bowl, the water in the bowl envelopes the collector, initiates dissolution of the primary components of the device, and the protective layers of the device, which are relatively weak, collapse or disperse once the primary layers of the device lose their structural integrity.  Thereafter, the entire device can be flushed through the water discharge lines without obstructing or damaging the waste water system.
