Title: Panels for lining the outer face of walls
Inventor: AKKAYAN AYHAN
IPC: E04F13/12
Filed: 1994-01-28
Abstract: ABSTRACT      Lining for the outer face of vertical or inclined walls, composed of identical quadratic panel elements, placed with their diagonals parallel to the edges of the wall, and of triangular elements, whose shape corresponds to the triangles won by dividing the quadratic elements once or twice along their diagonals.  The triangular elements are placed along the edges and corners of the wall and are provided with a flap bent 90° which serves to fix them along the edges of the wall.  All edges of the panel elements parallel to the diagonals of the quadratic elements are provided with folds bent at an angle of 180°, which can be slid into one another, whereby the folds of the edges pointing up toward the top of the wall are folded outward and the folds of the edges pointing down toward the bottom of the wall are folded inward.      The lining is laid by beginning with a first row of triangular elements along the bottom of the wall.  The next row of quadratic and triangular elements is laid and fitted to the first row by sliding the folds into one another, fixing the upper corner of the quadratic elements by nails or pins.  After covering the whole wall in this manner, a con-tinuous lining is obtained which is impervious to water running down along the wall.      Panel elements of shapes other than quadratic can be used, e.g. of rhombic shape, combined with triangular elements won by diagonally dividing the rhombs.

IPC: B66C13/06
Filed: 1993-06-01
Abstract: In the hoisting device with a horizontally movable structural component (e.g. a crab 1; 1'; 1"), in order to prevent swinging and increase the transfer capacity, the means for grasping the load (e.g. a spreader 4) is suspended via six or more hydraulic ad-justing cylinders (11 to 16;41, ...; 51, ...), the length of which is individually adjustable, which are supported via a movable coup ling (21 to 26 and 31 to 36; 59, 60) on the crab (1; 1'; 1") and on the spreader (4).  Here, at least four adjusting cylinders (11 to 16; 41 to 44; 55 to 58) are fitted obliquely. The couplings (21 to 26 and 31 to 36) of the adjusting cylinders are arranged on both the crab (I) and the spreader (4) preferably on a mathematical circle (20 or 30). With a purely vertically acting load it can be of ad-vantage to have eight adjusting cylinders (51 to 54; 55 to 58) of which four (51 to 54) are vertical and lie at the angles of a mathe-matical rectangle or square in plan view.

Patent CA-2141224-A1 (CA)
Inventor: FOX THOMAS M
IPC: G01S1/04
Filed: 1995-01-27
Abstract: A transmitter (12) broadcasts a PN encoded message (16).      A receiver (14) includes a SAW correlator (38) configured to autocorrelate with the PN sequence used in the broadcast signal.      A preamble of the message (16) conveys two successive bits (18) that are each encoded with the PN sequence. After the correlator (38) has been preloaded with the PN sequence from the first bit (18), its non-correlation output exhibits reduced amplitude time sidelobes. A timing comparison circuit (60) compares a correlation signal (46) with a timing threshold (72). The timing threshold (72) is established at a very low level to minimize the influence of multipath. False triggering on noise is prevented by disabling the timing comparison circuit (60) until after the first bit {18). At this point in time the correlator (38) has been preloaded with its PN sequence, is again being loaded with its PN sequence, and outputs reduced amplitude time sidelobes.

Title: Efficient point to point and multi point routing mechanism for programmable packet switching nodes in high speed data transmission networks
Inventor: LEBIZAY GERALD
IPC: H04L12/56
Filed: 1995-03-10
Abstract: The present invention relates to an efficient point-to-point and multi-points routing system and method for programmable data communication adapters in packetswitching nodes of high speed networks. The general principles of this efficiency are as follows. First, data packets are never copied, only packet pointers are copied for each destination, Space in Buffer Memory is saved, the number of instructions is significantly reduced improving the packet throughput (number of packets per seconds that the adapter is able to transmit).  and the routing is independent of the packets length. Second, no overhead is generated by the multi-points mechanism in the real time procedures, the underrun/overrun problems on the outputs are reduced and the efficiency of the adapter in term data throughput (bits per second) is significantly improved. Third, each output is processed independently by means of interrupts, lines are managed in real time and lines of different speed or protocol can be supported in parallel. Fourth, the release of the resources is entirely realized on a non priority mode.

Title: A luminance weighted discrete level display
Inventor: SILVERBROOK KIA
IPC: G02F1/1343
Filed: 1995-03-13
Abstract: The construction of display devices often involves the replication of a single pixel design a large number of times. Full colour display devices are often constructed on the principle of utilising multiple primary colours in order to form a final destination colour. Previously, the degree of complexity of the pixel arrangement devoted to each primary colour was substantially the same. The present invention discloses devoting a variable degree of complexity to each primary colour in a pixel layout depending on the perceptual response of the human eye to the particular primary colour. For example, there is disclosed a pixel arrangement having red, green and blue primary colours wherein substantial complexity is devoted to the green primary colour with a lesser complexity devoted to the blue primary colour.

Title: Low friction solenoid actuator and valve
Inventor: RIEFLER ROGER G
IPC: H01F7/16
Filed: 1993-09-21
Abstract: An actuator (24) for a valve (10) includes a housing tube (26) enclosing an internal cavity (48). A plunger (42) is mounted for movement in the internal cavity. The plung-er includes four slots (50). Rollable spheres (58) are posi-tioned in the slots between staked areas (62). A magnetic field created by electrical current passing through a coil (34) moves the plunger downward to open fluid flow through a control element (20). Flow through the control element enables controlled flow from an inlet (14) to an outlet (16) of the valve. The actuator construction provides for substantial elimination of sliding friction acting on the plunger, reduces hysteresis and the amount of power re-quired to move the plunger, and facilitates accurate control of fluid flow rate through the control element.

Title: Fill and Pressurization Apparatus
Inventor: CUDINI IVANO G
IPC: B21D31/00
Filed: 1995-05-17
Abstract: Fill and pressurization apparatus having a sectional fluid conductor (27) having a first section (27a) fixed relative to the surroundings, and a second section (27b) which moves toward the first section (27) to form an enclosure (Fig. 2) through which a high volume flow rate -low pressure flow may be passed to fill an adjacent open end of a tube (17) with liquid.  Said fluid is passed through an inlet conduit (38), which may be a rigid conduit, to the fixed first section (27a).  A seal head (77) insertable into the end of the filled tube (17) has an elastomeric seal member (87) and a rod (76) and a sleeve (78) relatively axially displaceable to compress the seal member (82) and deform it into sealing engagement with a surface of the tube (17).  A stop member (84) on one of the rod (76) and sleeve (78) and a stop surface (81a) on the other of the rod (76) and sleeve (78) limit the axial displacement and hence also the compressive force applied to the seal member (82).  The relative displacement is achieved by retracting one of the rod (76) and the sleeve (78) and blocking the retraction of the other.  The blocking is provided by two telescoping cylinders (89 and 96), one (96) of which has abutments (99) thereon running in channels (101) provided in the other cylinder (89).  To effect blocking one cylinder (96) is rotated relative to the other so that the abutments (99) are out of register with the channels (101) and engage stop surfaces (103) in an extended condition of the cylinders (89 and 96) relative to one another.
