Patent CA-2055671-A1 (CA)
Inventor: HAYES STEPHEN
IPC: A47C20/08
Filed: 1991-11-15
Abstract: A bed - Figure 1 - comprises a profiling mattress frame. Backrest 42 is arranged to be lifted by actuator 58 via a crank 56, and thighrest 46 similarly by actuator 60. Legrest 48 is freely pivoted to the thighrest. The angles of the parts are sensed and maintained in proportion by control means, so that as if for example the backrest angle 42 is steepened, the thighrest 46 is also raised in proportion but to less extent, taking the legrest 48 with it.

Patent CA-2062308-A1 (CA)
Inventor: LIU TUNG Y
IPC: B64G1/38
Filed: 1992-03-04
Abstract: An improved method for transitioning a spacecraft from a thruster (1) controlled, station keeping mode to an operational, on-orbit mode, in which attitude control is maintained using internal momentum wheels (3).  The method first utilizes a thruster compensation technique to supplement the conventional transition mode control system.  This compensation uses empirical thruster data to derate thruster (5) efficiency for extremely short pulse durations necessarily used in transition mode operation.  Secondly, a three step deadbeat thruster (5) sequence is employed in which a first pulse linearizes spacecraft (1) motion prior to orienting and stopping nutation.  This linearization provides improved accuracy in computing and shortens the waiting time for subsequent thruster (5) firings.

Title: Tilt back chair and control
Inventor: OLSON OGDEN R
IPC: A47C1/032
Filed: 1992-06-05
Abstract: A tiltable chair has a base, a vertical post, a seat, a back and a chair control. The chair control comprises a housing attached to the vertical post, a resilient biasing means mounted in the stationary housing for biasing the chair in an upright position, a seat support structure, a back support structure and a back frame member. The seat support structure is pivotally connected to the housing at a pivot axis aligned over the vertical post. The back support structure is pivotally connected to the seat support structure at an axis forward of the vertical post. One end of the back frame member supports the back support structure while a mid-portion is interconnected to the seat support structure and the opposite end is pivotally attached to the housing to provide both differential tilting of the seat and back and correlated differential vertical movement for ergonomic comfort and to avoid "shirt pull." A spring mount assembly comprising compression springs compressed between the front portion of the seat and the seat support structure provides resilient but flexible seat support. A base cover assembly comprises top and bottom fairings which form a friction fit with the base and which also snap fit together to provide a smooth, attractive appearance.

Title: Grout composition
Inventor: ROOSHENAS REZVAN
IPC: C04B26/14
Filed: 1993-01-12
Abstract: ABSTRACT OF THE DISCLOSURE        The present invention features an indelibly colored grout composition and a method of making it.  The grout of the invention mixes pre-colored materials such as stone, sand, plastic or ceramic aggregates with a resin binder.  In the case of ceramics, the materials are pre-colored and color-fast, so that they resist fading and attach from stains and chemicals.  The color-fast materials can be natural or man-made and, if man-made, can be pretreated, and permanently coated.  In the case of stone, the natural colors are permanently inherent in the stone matrix and will not fade or leach out.  An ultraviolet blocker is also added to the mixture to prevent the binder from yellowing when exposed to sunlight.  This admixture also contains an anti-oxidant to prevent the change of color by reason of oxidation.  A thixotropic agent is added to provide the desired consistency, which eases the workability and application of the grout.  The mixture may also contain an air-release agent.  The pre-colored aggregates may be of a single color; however, it has been found to be advantageous to mix differently colored aggregates with the binder. Such a multi-colored or speckled grout gives the appearance of a single color when viewed from an extended distance; it also blends more readily with multi-colored tiles and masonry materials.

The cogged wheel is integral with the rotating shaft; its teeth engage the teeth of toothed segments which face each other, and each of which is situated at the extremity of a coupling element with a coupling strip; the free end of the coupling element is shaped as a carrier for the neighbouring runner. The strip blind can be operated by using a rod, chain, or the like.  Lateral movement of the strips is possible either in a completely of partially closed position.
Patent CA-2090671-A1 (CA)
Inventor: FISK ALLAN T
IPC: B23P19/02
Filed: 1991-09-18
Abstract: This invention is a new apparatus for installing press fit couplings about steel pipeline sections. Conventional apparatuses are extremely large, usually requiring extensive mounting equipment, and are incapable of being used in the confined spaces of a pipe trench. This invention solves the problem with a small, compact pipe coupling apparatus which is easily maneuvrable in tight spaces. The apparatus (10) fits within two pipes (1, 2) to be joined, with a coupling (3) disposed between them. Two hydraulically actuated grippers (6, 7) grip the insides of both pipes (1, 2), respectively, and a hydraulically actuated cylinder (5) is operated to pull the pipes (1, 2) together, press fitting the coupling (3) about them. The entire apparatus is controlled using only two hydraulic lines (8). The grippers (6, 7) can be retracted and the apparatus moved within the pipeline from one joint to the next. The invention is also applicable in joining two sections of pipe without the use of a coupling.
