Patent CA-1302058-C (CA)
Title: Concrete brick and process and apparatus for fabrication thereof
Inventor: RUCKSTUHL WILLI
IPC: E04B2/02
Filed: 1988-06-03
Granted: 1992-06-02
Abstract: ABSTRACT OF THE DISCLOSURE       Apparatus for fabrication of concrete bricks having at least one visible surface with a texture similar to that of natural stone.  The brick is made by filling a mold with concrete, vibrating the mold, and using a descending plunger to compress the concrete in the filled mold. At least one interior surface of the mold has a textured surface used to form the texture in the brick.  Following compression of the concrete t a movable sidewall of the mold is moved laterally away from the brick a distance sufficient for the textured surface of the mold wall to clear the textured surface of the brick when the mold is raised.  With the plunger remaining in place, the mold is raised, following which the plunger is raised.  Lateral movement of the mold is effected by a cam element fixed on a slide plate, the cam element having its cam surface engaging a bolt fixed to the moving sidewall and biased outwardly from the mold.  As the cam surface slides over the bolt, the outward bias of the bolt causes it to follow the cam surface and thus move the sidewall back and forth. Because the movable sidewall can be laterally cleared from the molded brick, the latter can have, for instance, an overhanging and textured visible surface, which is not possible using conventional molds.

Granted: 1993-07-20
Abstract: ABSTRACT OF THE DISCLOSURE A self-watering planter (10) includes an outer shell (11) and an inner liner (12) nested within the shell (11).  A reservoir (21) for water is formed therebetween.  A wick (22)transfers water from the reservoir (21) to the plant rooted within liner (12).  A water intake and float tube assembly (13) includes an intake column (42) for transmitting water to the reservoir (21).  A float tube (25) houses a float rod (27) which carries a float (29) at the bottom thereof giving a visual indication of the level of the water in the reservoir (21) at the top of the assembly (13).  A cylinder (41) protects the float (29) from turbu-lence which might be created when water is transferred to the reservoir (21) through column (42) so that no false readings as to the water level are created.

Title: Method and apparatus for winding a web
Inventor: SNYGG KEIJO
IPC: B65H18/16
Filed: 1989-02-21
Granted: 1993-08-10
Abstract: (57) Abstract The invention relates to a method and apparatus for on-machine winding of a web. in which a Pope reeling drum (10) is used, over which the web (W) to be wound passes. A reel spool (11) is driven by so-called centre drive. New reel spools (11') are brought into connection with the reeling drum. after which the web (W) is conducted away from a fully wound roll to to be wound onto a new reel spool.  The method comprises, in combination, the following steps: an empty reel spool (11') is brought into the grip of primary arms in such a way that bearing members (25) at both ends of the reel spool (11') are being supported by guiding elements at each end of the reeling drum (10) in such a manner that the outer shell of the reel spool (11') is not engaged with the reeling drum (10). The empty reel spool (11'), preaccelerated to winding speed, is brought into nip contact with the rotating reeling drum (10), at the sides of which guiding plates (20) provided with recesses (21) are attached, at which recesses the reel spool (11') is placed. through which nip the web (W) to be wound passes. Due to said nip contact, or only after it, the web is breaks off or is severed by means of a double-sided adhesive tape wrapped round the reel spool (11'), whereby the web (W) begins to wind onto the empty reel spool (11) and the winding is continued by centre drive of the reel spool (11) and/or nip drive until the roll is fully wound, after which the above steps are repeated. The winder in accordance with the invention can, with an auxiliary device, also be driven by conventional nip drive.            (Fig. 1)

Patent CA-1332876-C (CA)
Inventor: HOLZER WALTER
IPC: F25D17/06
Filed: 1989-05-19
Granted: 1994-11-08
Abstract: The frost-free refrigeration process known up to the present is based on the principle that super-cooled air is circulated through the actual cool chamber.  This super-cooling of the air leads to the fact that the humidity in the air is deposited on the evaporator, with the result that very little humidity is left in the air.   This leads to the foodstuffs contained in the refrigerator becoming desiccated, and for this reason, such foodstuffs have to be packaged so as to be as close as possible to airtight in order to avoid such desiccation.  The present invention proposes that cold be supplied to the cool chamber by convectors, and any decrease in temperature below the desired range be regulated by the controlled delivery of fresh air at a higher temperature.    In order to avoid any loss of performance by the quantity of heat that is supplied, the cold air that is displaced is passed to a heat exchanger of the condenser of the refrigerating machinery.    Since the circulation of the fresh air is always effected in a range above 0°C, the fresh air that is delivered can be regulated as far as its moisture content is concerned and can be filtered so as to ensure the elimination of odours.

Title: Link utilization control mechanism for demand  assignment satellite communications network
Inventor: GERHARDT ED
IPC: H04J3/26
Filed: 1989-08-18
Granted: 1995-10-24
Abstract: A link utilization control mechanism for a demand assignment  satellite  communication  network  employs  a modified point-to-point communications protocol (X.25) in order to simulate point-to-point communication ports and thereby interface what is effectively a multiddrop network with  point-to-point  landlink  communication  resources. Through an acknowledgement reservation mechanism the return link  channel  is  subdivided  into  interleaved  data  and (preassigned)  acknowledgement  time  slots,  in  order  to substantially obviate overhead and throughput penalties encountered in the use of large data packets to transmit reduced size acknowledgement messages.   In addition, the normal contention mode of operation of the return link is augmented with a data time slot reservation mechanism through which, during periods of increased message input density at a remote station, transmission throughput is facilitated, so that congestion at the remote station is reduced.

Title: Vertical deflection circuit
Inventor: SUTHERLAND HUGH F II
IPC: H04N3/16
Filed: 1990-05-24
Granted: 1991-10-08
Abstract: Abstract A vertical deflection amplifier of a video display apparatus includes first and second transistor amplifier output stages arranged in a totem-pole, push-pull configuration.  A vertical deflection winding is coupled to the output stages at a deflection amplifier output terminal.  An s-capacitor is coupled to the deflection winding at a second terminal remote from the output terminal.  A source of deflection rate signals is coupled to the deflection amplifier for generating a deflection current in the deflection winding.  A base current generating circuit is coupled to one of the transistor amplifier output stages for providing base current thereto. The S-capacitor voltage is applied to the base current generating circuit for enabling conduction of base current in the one amplifier output stage.  When the video display apparatus is first turned on, the initially discharged S-capacitor is slowly charged from a DC voltage supply to delay generation of vertical deflection past completion of picture tube degaussing.
