Patent CA-1281178-C (CA)
Title: Apparatus for coating substrate devices
Inventor: BOYARSKY DAVID
IPC: G11B7/26
Filed: 1987-09-29
Granted: 1991-03-12
Abstract: Apparatus for Coating Substrate Devices Abstract of the Disclosure The present apparatus has a movable table with apertures therein.  In each aperture there is loaded a carrier device and each carrier holds a substrate to be coated.  The carriers are advanced in a step-like fashion to a loading position under a vertical hollow cylinder.  When a carrier is in the loading position, a piston is moved upward, passing through the aperture, pushing the carrier into the hollow cylinder.  Each carrier has an O-ring on its periphery and the O-ring is squeezed against the cylinder wall to form a seal.  Each carrier pushes against the one above it to advance a column of carriers upward in the hollow cylinder.  In this way, the carriers, and the substrates they hold, pass through the hollow cylinder.  Along the cylinder there are vacuum stations which act to pump down and degas the substrates.  The degassed substrates eventually emerge from the upper end of the cylinder into a vacuum chamber, whereat they are coated by sputtering, or the like.  The vacuum level in the coating chamber is not as low as the vacuum level at the vacuum stations along the cylinder.  Accordingly, gasses in the coating chamber tend to try to escape into the vertical cylinder but are stopped by the O-ring seals on the carriers.  Hence the coating chamber is not contaminated.  The substrates are transmitted through the coating chamber, coated, and withdrawn therefrom through a second hollow cylinder.

Granted: 1991-08-20
Abstract: (100A/2) "Multipoint Data Communication With a Supervisory System for Detecting a Malfunctioning Remote Station"                  ABSTRACT OF THE DISCLOSURE A random access multipoint data communication system comprises a central station and a plurality of remote stations.  A multiple access channel is established from the remote stations to the central station and a broadcast channel is established from the central station to the remote stations.  The central station generates a timing signal for causing each of the remote stations to define commonly shared time slots on the multiple access channel.  Each remote station transmits data on a randomly determined time slot of the multiple access channel.  The central station periodically and sequentially interrogates the remote stations to return an acknowledgment and processes the returned acknowledgments to determine the presence of a malfunctioning remote station.  To avoid data collision, the central station specifies an idle time slot on which the interrogated remote station is requested to send the acknowledgment.

The angle formed between the upper and lower portions may be maintained at the desired angle by a clamp member 13 connected to an offset axis of the hinge arrangement 14 and bolted to the upper portion 11.  The frame comprises a seat support member 15 extending from and releasably attached to the hinge arrangement 14 at one end. The other end is supported by a front member 16 which is connected to the front wheel(s) 17.  The rear wheels 19 are connected to the lower portion 12 by wheel mounts 18 which may be rotated to raise or lower the height of the lower portion 12 to cause a variation of the orientation of the seat fitted to the frame.  Thus the orientation of the seat may be varied as well as allowing the back of the seat to be reclined.  The seat and footrest may be connected to the frame by adjustable mounting blocks 45.  Advantageously, the frame is fitted with a seat formed from an extendable seat form to form the mobile chair.  The seat form, the internal structure of a seat to which the seat owes its shape and to which padding is applied may be of two basic configurations.  The first configuration of the seat form 60 ...2/   5984S/liz                      -1-has a integrally formed back portion 61 and base portion 62.

Title: Method and apparatus for separation of sulfur dioxide  from gases, particularly exhaust gases from combustion processes, such as flue gases
Inventor: FULLEMANN JORG
IPC: B01D53/34
Filed: 1988-06-28
Granted: 1993-06-29
Abstract: ABSTRACT OF THE DISCLOSURE       To prevent the formation of encrustations on a pH sensor in a combustion exhaust or flue gas washing apparatus, alkaline    additives are added to the wash water which, upon contacting   SO2  in the gases, form  sulfite particles.          The sulfite particles are prevented from depositing a  the bottom of a collection vessel (11) in form of a mud,  and, in accordance with the invention, rather are continuously stirred and re-circulated in a closed recirculation loop to a spray device (25).     The particles, upon being recirculated, will grow to form a granulate  which, eventually, will deposit, the granulate, however, being constituted by granules substantially in excess of those which form a  mud; the larger granules also prevent deposition of encrustations along the walls, and, for example, a  pH  sensor (47).  The washing liquid within the tank or vessel 11 can be held in continuous turbulence or agitated form by a stirrer (53) coupled for example to the shaft of an immersion pump (21), an  additional stirrer, by a recirculating fluid   injection nozzle (57) or by directing run-off sprayed water into the tank by a direction and collection vane (28).  Preferably, oxygen is excluded from the gases to prevent the formation of sulfates, and the washing liquid is held at a temperature below 40°C by a suitable heat exchanger which can supply hot utility water.  A preferred  pH is between 6 to 6.5.

IPC: G11B5/127
Filed: 1988-07-13
Granted: 1992-01-07
Abstract: ABSTRACT OF THE DISCLOSURE     A magnetic head comprises a pair of magnetic core halves, heat-resistant thin films and ferromagnetic thin films, the pair of magnetic core halves being opposed to each other through a non-magnetic material such as SiO2 to form a magnetic gap.  The magnetic core halves are made of a ferromagnetic oxide such as ferrite and have gap forming faces to be opposed to each other to form the magnetic gap.  The gap forming faces are etched by phosphoric acid solution and then purified by reverse sputtering, so that a grown crystal of the ferromagnetic oxide is exposed on the gap forming faces.  A heat-resistant thin film of a heat-resistant material such as SiO2 is formed on each of the gap forming faces.  A ferromagnetic thin film of a ferromagnetic metal material such as sendust is formed on each heat-resistant thin film.  Preferably, the thickness of the heat-resistant thin film to be formed is 1 nm or more and one tenth or less of the width of the magnetic gap.  For example, SiO2 films of 5 nm in thickness as the heat-resistant thin films are formed on the respective gap forming faces and senddust films of 3 µm in thickness as the ferromagnetic metal thin films are formed on the respective SiO2 films.  In this case, the gap length of the magnetic gap is set to 0.2 µm.

Granted: 2001-07-10
Abstract: A flexible and stretchable sheet material that is capable of being stretched to conform to a three-dimensional substrate to form a protective and decorative coating thereon is comprised of a thin flexible support having adhered thereto a protective and decorative layer such as a paint layer comprising a colorant incorporated in a film-forming binder. Both the support and the protective and decorative layer are characterized by a very high degree of thickness uniformity and the sheet material exhibits a high level of surface uniformity, an ability to undergo substantial elongation, and a substantially uniform quality and appearance; whereby it can be stretched and bent in the process of bonding it to a substrate and still achieve a defect-free coating of uniformly attractive appearance. A process for the manufacture of the sheet material comprises the steps of: providing a flexible support sheet; providing a fluid protective and decorative film-forming composition; forming a laminar flow of the composition and directing the flow into contact with the surface of the support to form thereon a protective and decorative layer of substantially uniform thickness; and converting the protective and decorative layer to a dry and tack-free state. In one preferred embodiment, the protective and decorative layer comprises a film-forming binder, a colorant and generally flat light-reflecting particles which are effectively oriented by the laminar flow process to provide a layer characterized by a high degree of geometric metamerism. Vacuum-forming and thermoforming techniques can be effectively employed to bring about the application of the sheet material to structural substrates, such as exterior automotive panels, to which it can be glued or otherwise securely bonded in a smooth and wrinkle-free stage.
