Patent CA-1298565-C (CA)
Inventor: DUBROW ROBERT S
IPC: B29C71/04
Filed: 1986-05-01
Granted: 1992-04-07
Abstract: Abstract This invention provides organopolysiloxane materials having cone penetration between about 100 and about 350 (10-1mm) and ultimate elongation of at least 100% and having reduced surface tack.  This invention provides three methods of obtaining said materials with reduced surface tack.  The first method comprises applying to the surface of such material an organic peroxide or a photoinitiator and irradiating the surface with ultraviolet light to        crosslink the surface to reduce or eliminate the tack of the surface. The second method comprises mixing a photoini-tiator, such as benzophenone, in an organopolysiloxane fluid, thermally crosslinking the organopolysiloxane fluid to produce the material with the above cone penetration and ultimate elonga-tion then irradiating the surface of the material with ultra-violet light to reduce or eliminate the tack of the surface. The third method comprises mixing a photoinitiator, such as ben-zophenone, in an organopolysiloxane fluid, crosslinking the fluid by irradiating a layer of the fluid with ultraviolet light to produce the above cone penetration and ultimate elongation pro-perties then further irradiating the crosslinked material to reduce or eliminate the surface tack; this method can be carried out by simultaneous irradiation with ultraviolet light from two sides of a layer of the organopolysiloxane wherein one surface is irradiated at a higher intensity than the other surface.  The materials produced by this invention are useful as tapes and sealants.

Title: Plastic pipe connection
Inventor: BUERLI KURT
IPC: B25B27/10
Filed: 1986-11-10
Granted: 1993-11-02
Abstract: ABSTRACT         A coupling sleeve pushed onto the plastic pipe and provided with barbs is drawn over a driving shoulder against the connecting piece by a union nut.  The flared pipe end is clamped between a curved end face of the connecting piece and the coupling sleeve.  Possible leakages caused by the flow of the pipe material are prevented by a spring, and the pipe is prevented from turning during assembly by a sliding ring.  The device used for assembling the pipe connection has grips for fixing the pipe in position with a toggle lock and a press ring, which can be displaced in sliding manner on a stop acting as a centering arbor, and can be actuated by a hand lever.  With only a few manipulations, the coupling sleeve can be pushed onto the centrally held plastic pipe.  Owing to the omission of the supporting sleeve required hitherto, the through-flow cross-section of the plastic pipe is not reduced by the installation of this pipe connection.  Heating up the end of the plastic pipe is no longer necessary during assembly.  The pipe connection, which can be made cost effective, is uncomplicated in its construction and absolutely liquid-tight.

Abstract: Abstract Apparatus And Method For Controlling A Force Commutated Inverter A method and apparatus is disclosed for generating thyristor gating signals for a force commutated inverter in order to produce variable frequency pulse-width modulated output waveforms with the appropriate percent fundamental voltage content for reactive power control and with the correct phase relationship to the utility line for real power control.  A signal processor in conjunction with a memory is used to store individual patterns for generating a wide variety of PWM waveforms at different frequencies over the entire modulation range so as to provide the designer with the flexibility to select the most advantageous harmonic cancellation for each operating point.  An embodiment of the invention disclosed uses three microprocessors to generate the PWM waveforms and a fourth microprocessor to synchronize the other three and produce the required phase shift.  The principles disclosed apply to inverters used and controlled in parallel with a grid of real and reactive control signal commands and also those used independently by means of voltage magnitude commands.

Title: Automatic touch actuated door opener
Inventor: ZIEGENBEIN KEITH J
IPC: B65F1/16

Granted: 1991-02-26
Abstract: Abstract of the Disclosure The  automatic  touch actuated  door  opener  includes   an elongated  flexible tension member having one end connected to  a door  and  the  other end connected to a tension  member  take-up device.   The door is biased to its closed position for maintain-ing  tension in the tension member when the door is moved to  its closed  position.   A switch in contact with the  tension  member senses  decreased  tension  due  to  external  touching  pressure against the door and actuates the take-up device to automatically open the door.   A time delay switch causes the take-up device to allow  the  door  to  return to its  closed  position  after  the preselected  time interval.   An alternate emobidment includes  a pair  of  limit  switches  which  are  sequentially  engaged  and released   in   response  to  increased  and  decreased   tension respectively in the tension member.

Abstract: PHN 11.915              24              04.02.1987 ABSTRACT:          Method of recording a binary signal on an optically readable record carrier and apparatus for carrying out the method.     A method and apparatus are described for re-cording a binary information signal (Fig. 2a) on a record carrier (1) having an information layer (2) whose optical properties are modified upon heating.          An information pattern corresponding to this informa-tion signal (Fig. 2a) is obtained in that the record carrier 1 is moved relative to an optical system (3) for focussing a radiation beam (4) on the information layer (2), a subsequent recording mark (5) being written on the information layer (2) in selected time inter-vals (?) by locally heating the information layer by means of the radiation beam (4). The amount of radiation energy (E) applied in a selected time interval depends on the position of the selected time interval (?) in the sequence of consecutive selected time intervals (?). This provides compensation for the influence of the radiation energy (E) applied in the preceding time interval ( ? ) on the temperature at the location of the recording mark (5) to be written in the time interval (?), so that for each recording mark (5) the temperature (Tr) which is reached in the informa-tion layer (2) and hence the size of the recording mark (5) is substantially the same.

Abstract: EROSION CONTROL FOUNDATION MAT AND METHOD                ABSTRACT OF THE DISCLOSURE         An erosion control structure and method involves placing a large permeable mat with peripheral weighted pockets around and attached to the mat on the bottom of the body of water such that at least a portion of the mat extends to a location where currents have a velocity sufficient to erode the bottom.  The peripheral pockets are filled with a weighted material, such as sand.  Large weighted stabilizers are placed on the mat and positioned in the areas where the currents exceed the erosion velocity such that the stabilizers are below the surface of the water.  The stabilizers are elongated tubular elements filled with a cementitious material, and preferably a large diameter tubular element is secured between two smaller diameter tubular elements.  The smaller tubular elements are filled first in order to control the position of the larger diameter tubular element during filling.  Further, a crossing tubular element is preferably positioned across a shoreward end of the elongated tubular element in order to form a barrier against wave movement around and past the shoreward end of the elongated tubular stabilizer.
