Title: Silica coated titanium dioxide
Inventor: MELDRUM BRIAN JOHN
IPC: C09C1/36
Filed: 1990-03-26
Abstract: A particulate titanium dioxide has a coating of dense amorphous silica. The particles have a size of 0.01 to 0.15 micron, may be spherical or acicular and are absorbent to UV light and transparent to visible light.

Title: A flap valve
Inventor: GARDNER FREDERICK BASIL
IPC: F16K15/14
Filed: 1990-03-27
Abstract: A flap valve comprising an annular frame (10) defining an opening (11) through which liquid may flow in one direction, a closure flap (14) for said opening connected to the frame (10) by a hinge member(15), and a valve seat (12) against which the closure flap (14) may close to prevent reverse flow of liquid through the opening.

Title: System containing expendable isolation valve with frangible sealing member, novel seat arrangement and method for use
Inventor: ECHOLS RALPH H
IPC: E21B47/10
Filed: 1991-06-27
Abstract: An isolation valve for a downhole well completion system has a one piece frangible, ceramic sealing element (410) and an extrusion resistant resiliently faced valve seat (30). Said sealing element is biased to the closed position and rotatable within a sealing element chamber (207) from an open position during run in to a closed position as a result of the withdrawal of a wash pipe and a protector tube from the valve bore. Said frangible sealing element cooperates with said extrusion resistant valve seat to provide a reliable pressure resistant seal. A method of use of the sealing element (410) is described in which, in a well completion operation and after recovery of completion fluids from the well bore and pressure testing of the production string, the frangible sealing element (410) is shattered by impacting with a tooth-faced blind box hammer. <IMAGE>

Title: Foot-operable hand-held tools
Inventor: STEEDS GORDON
IPC: A01G3/02
Filed: 1991-07-23
Abstract: Foot-operable hand-held secateurs or pruning shears (1) have a flexible connector cable (2) extending between a pivoted blade (3) of the blade pair (2, 5) and a remote pedal control arrangement (4). The blades are biassed to "open" via spring (15) and the pedal to "up" via spring (12). Alternatively, the pedal may be connected to the pivoted blade by a fluid pressure piston and cylinder arrangement. The tools provide great advantages to users who are able to hold the elongate handle (6) but whose grip would be too weak or painful to operate corresponding conventional tools in which the blade pair is closed manually. <IMAGE>

Title: Reducing cage vibration in a lift
Inventor: SUGAHARA JUN
IPC: B66B7/04
Filed: 1993-08-12
Abstract: An elevator apparatus is provided with a guiding device 7 which guides a passenger cage 4 without vibration with regard to guide rails. Sensors detect the bend of the rail 6 and plurality of signal patterns averaged over a number of runs is stored in a memory. That data is then used to drive actuators 9 such that the distance between the guide rail and the cage is decreased. Accordingly, the guiding device thus closely follows the bend of the guide rail so that the transversal vibration of the passenger cage is greatly reduced. <IMAGE>

Title: A wall anchor gun structure
Inventor: HUANG PANG CHING
IPC: B25B27/00
Filed: 1994-01-21
Abstract: A wall anchor gun structure enables a user to squeeze a thread seat (2) of a wall anchor forward into a wall with little force. The gun structure includes a gun body (20) having a downwardly extending fixed handle (21), a movable handle (30) disposed in front of the fixed handle, two driving plates (40), a trigger seat (50), a trigger (51), a driving rod (60), a bolt seat (61), and a stopper plate (70). Several springs are fitted on the driving rod (60) to bias parts of the gun. The trigger seat (50) prevents the driving rod moving rearwardly during the inward movement of the expansion bolt (2). When the driving rod (60) rearwardly drives the expansion bolt, the stopper plate (70) abuts against and forces the thread seat (2) to move forward, squeezing a tail end (2A) thereof forward into a fixed position and thus fixing the thread seat (2) on a wall. <IMAGE>

Abstract: An open barrel type crimp terminal having a body (A0) of semicircular cross section which is adapted to surround an end of an electric wire (W). A pair of claws (A1, A2) extend integrally from the ends of a circular arc of the body and are adapted to be crimped on the end of the electric wire. Also disclosed is a method of caulking the crimp terminal on the end of the electric wire. The body containing the end of the electric wire is placed on a stationary pressure receiving member. One of the claws extends a predetermined length longer than the other claw with respect to a movable pressing member that caulks the crimp terminal with the pressure receiving member. The pressing member is displaced towards the pressure receiving member for bending the longer claw over the other claw so that the longitudinal claw laps over the other claw. <IMAGE>

In another embodiment (Figure 3) the ball and socket joints are replaced by cuboid protrusions (34) and complementary cuboid recesses (35) which allow limited movement between adjacent links. Resilient prongs (23) allow the bend limiter to be mounted on an equipment rack. The links may be coated with an adhesive which melts on heating so that the bend limiter takes a set shape on cooling. <IMAGE>

Title: Hydraulic master cylinder switch
Inventor: SALZMANN DAVID F
IPC: B60T11/16
Filed: 1994-04-05
Abstract: A switch mounted on the push rod of a master cylinder assembly and controlling in sequence several switches such, for example, as a cruise control switch, an electronic fuel injection switch, and a start interlock switch. The switch includes a hollow housing defining a central chamber through which the push rod passes and a plunger assembly carried by the push rod and mounted for axial movement within the chamber. The plunger assembly includes a primary plunger and a secondary plunger carried by and movable axially relative to the primary plunger. The initial portion of the forward movement of the push rod allows incremental forward movement of the secondary plunger to actuate a first series of switches whereafter the push rod moves further forwardly without either plunger whereafter the push rod engages the primary plunger to move the plunger assembly forwardly to actuate a further switch. The lost or relative movement between the push rod and the plunger assembly allows the switch housing to be significantly shortened and thereby allows the switch to be utilized on relatively short push rods. <IMAGE>

IPC: G09F15/02
Filed: 1995-01-31
Abstract: The invention relates to a method and an installation for arranging poster material on elongate elements (12) for picture-changing signboards. According to the invention, the elongate elements (12) are placed side by side on a movable carrier 10 corresponding to their intended positioning in the signboard, whereupon the elements (12) are treated to loosen adhesive of the old poster material in a bath 24. The old poster material is removed by means of scraping devices 28, and the carrier 10 and the elements (12) are transferred to a station II with a magazine 30 for poster sheets which are fed from the magazine and applied over the elements (12) and fixed thereon. Finally, the applied poster material is cut open between the individual elements (12) by means of a reciprocating cutting device 36. In an alternative arrangement, the carrier may be fixed and the various treatment stations movable. Some of the stations may be omitted e.g. 24 and 28, when the elements (12) are new or have been cleaned elsewhere. <IMAGE>

Title: Automatically scrubbing ECC errors in memory via hardware
Inventor: GONZALES MARK A
IPC: G06F11/10
Filed: 1995-03-01
Abstract: The present invention provides a method and apparatus for automatically scrubbing ECC errors in memory upon the detection of a correctable error in data read from memory. This is performed by providing in a memory controller memory control logic for controlling accesses to memory, an ECC error checking and correcting unit for checking data read from memory for errors and correcting any correctable errors found in the read data, a first data buffer for storing the corrected read data output from the ECC error checking and correcting unit and a writeback path having an input end coupled to an output of the first data buffer and an output end coupled to memory. Upon the detection of a correctable error in data read from a particular memory location, the ECC error checking and correcting unit signals to the memory control logic the existence of a correctable error in the read data. The memory control logic then obtains exclusive control over the first data buffer and the writeback path to control writing of the corrected read data onto the writeback path and subsequently to memory. <IMAGE>
