Patent GB-2124249-A (GB)
Title: Process for fluid catalytic cracking of hydrocarbons
Inventor: FANTINE JOSE
IPC: C10G11/04
Filed: 1983-07-07
Abstract: In a fluid catalytic cracking process, the virgin make-up cracking catalyst is added to the fresh charge to be cracked as a suspension in a hydrocarbon. A cracking passivator such as an antimony additive can be mixed into the suspension. This process is efficient for the processing of hydrocarbon charges of high metal content, and enables catalyst losses to be reduced by about 50 to 80%. <IMAGE>

Title: Controlling injection of fluids into wells
Inventor: STRICKLAND TUCKNESS CYNTHIA E
IPC: E21B34/14
Filed: 1983-10-08
Abstract: A side pocket mandrel 10 has an elongated receptacle 13 in the side pocket, parallel with the main bore. A lateral side port 21 communicates the receptacle with the exterior of the side pocket of the mandrel. A flow control assembly includes a sliding sleeve valve 30 and a control valve 40, both designed to be removable from the receptacle. The sleeve valve is movable within the receptacle between a closed position and an open position relative to the side port, and includes collet fingers 31 having outwardly projecting latching lugs 34 for engagement in a receptacle latching recess 18 in the closed position. The bore of the receptacle is slightly larger below the latching recess than it is above the recess, so that limited inward movement of the latching lugs, restrained by an insert within the sleeve valve, will permit movement of the valve downward to the open position but will not allow movement of the valve upward from the closed position, so long as the insert is in place. A control valve 40, to be selectively placed within the receptacle 13 and latched with the sleeve valve 30 includes a nose 44 which is received within the sleeve valve and limits the inward deflection of the collet finger latching lugs 34. The control valve includes a latching lug for latching in another receptacle latching recess, when the sleeve valve has been moved to the lower open position. The control valve and sleeve valve have a coacting latching mechanism so that when the control valve is withdrawn, it lifts the sleeve valve to the closed position and then disengages from the sleeve valve. The sleeve valve includes an internal latching recess to enable withdrawal of the sleeve valve from the receptacle by a suitable pulling tool. <IMAGE>

Title: Cutting guide
Inventor: MOELLER FRANK HEINRICH
IPC: B26B29/06
Filed: 1984-07-07
Abstract: A cutting guide comprises an inclined surface (3) provided with a rest (10). A tube (7) having a guide slot (8) is secured to the inclined surface (3) by screws (18) which extend through circumferentially extending slots (19) in the tube (7). The distance between the cutting edge (6) and the leading edge (4) of the cutting guide is normally equal to the distance between the leading edge (4) of the cutting guide and the trailing edge (5) of the rest (10). However, the position of the guide slot (8) may be varied by slackening screws (18) and rotating the tube (7) about its longitudinal axis. In use the trailing edge (5) of the rest is inserted in a corner and the material to be cut is lead over the leading edge (4), up the inclined surface (3) and over the tube (7). The material is then cut by a razor knife passed along slot (8). The cut material is either a perfect fit on the corner, or slightly larger or slightly shorter according to the chosen position of tube (7). <IMAGE>

Title: Spacing components usable as temporary formwork for casting concrete
Inventor: GREEN DENNIS WILLIAM
IPC: E04G9/10
Filed: 1986-02-06
Abstract: Spacing components are described for supporting a structure during the formation thereof, for example a building structure or foundation on expandable soil. The component consists of two box parts (1, 2) and an expandable core (11, Fig. 1B) e.g. of structural honeycomb (10, Fig. 1 B) between them. The box parts may be supplied fiat but pre-creased and/or slit and the core unexpanded for erection and assembly on site. The support may be used for a base on which concrete is cast, the support being subsequently destroyed by introduction of water into it after the concrete has set, subsequent expansion of underlying soil then does not exert undue pressure on the cast structure. <IMAGE>

Title: High purity copper wire for bonding a semiconductor device
Inventor: HOSODA NAOYUKI
IPC: H01L23/49
Filed: 1986-03-26
Abstract: An inexpensive, very fine wire of high-purity copper is disclosed as an alternative to the fine gold wire which is currently used in the bonding of semiconductor devices. The very fine wire of high-purity copper is prepared from a copper ingot that contains 0-2 ppm of S, 0-2 ppm of Ag, 0-1 ppm of Se and 0-1 ppm of Te as incidental impurities with the total content of these and any other incidental impurities present being held at a level not exceeding 10 ppm. By subjecting it to an appropriate heat treatment, the wire acquires an elongation of 5-22%, a breaking strength of 14-33 kg/mm2, and a Vickers hardness of 38-50, the latter value being measured with respect to said high-purity copper in an ingot form. By reducing the amounts of these impurities to even lower levels, very fine wires are obtained that can be used in the bonding of a semiconductor device without abnormally shaped loops being formed or wire breakage being experienced and the characteristics of the wires can be adapted to specific conditions of use by performing an appropriate heat treatment.

Title: Programmable logic controller system for hazardous environment
Inventor: CLAYTOR STUART RAYMOND
IPC: G05B19/05
Filed: 1986-07-03
Abstract: A programmable logic controller system for use in a hazardous environment has a microprocessor-based logic controller (10) and also a unit (30) incorporating a microprocessor and an alterable memory such as a RAM. This unit (30) can be coupled directly or indirectly to the controller (10) for testing and modification of a program. After testing the program is transferred to a non-volatile memory (43) outside the hazardous environment. This non-volatile memory (43) is then taken into the hazardous environment and fitted to the controller (10) for routine operation. This allows a program to be tested on the controller (10) before it is committed to the non-volatile memory (43). Preferably modification of the program is possible while working in the hazardous environment. Communication between the unit (30), any intermediate item of equipment and the controller (10) is preferably through opto-isolators to preserve electrical isolation. Serial data transmission is preferred. <IMAGE>

Abstract: In order to provide an improved arrangement for setting the radius to be drawn by a draughtsman's spring compass, the point (1) of the compass is carried by a cylindrical guide tube (2) which passes through a bore in a holder (3). One side of the holder (3) has a longitudinal slot (6) through which passes a pin (11) which pivots the other arm (9) of the compass to the holder (3), part of the arm (9) being received in the slot (6). The other arm (9) carries a drawing instrument such as a pen. The arms (2, 3 and 9) are sprung apart by a compression spring (10) extending generally at right angles to the axis of the tube (2) in the slot (6). The top end of the tube (2) mounts a rotary cam (5) against which the spring (10) biases a follower finger (12) on the top end of the arm (9). Rotating the cam (5) alters the distance apart of the arms (2, 3 and 9). <IMAGE>

Title: Hand-held labeler having improved web position sensing and print head control
Inventor: VANDERPOOL JAMES LACY
IPC: B41K3/02
Filed: 1987-03-18
Abstract: A hand-held labeler, e.g. with a thermographic print head, senses the position of the web to control the position of the imprints on the web. A circular indexing member having a plurality of position defining indices provides indications representative of the position of the web. The indexing positions include at least one home position index (142) and a plurality of positioning indices (148) adjacent the home position index. A warning track (154) is provided ahead of each home position index. Relative rotation between the circular member and the shaft is prevented by a plurality of key slots or the like disposed on said circular member and engaging a key on the shaft. The angular spacing between the key slots is unequal and is substantially greater than the spacing between the positioning indices; but the position of the positioning indices relative to the shaft may be adjusted by a distance less than the distance between the positioning indices by bringing a different one of the key slots into engagement with the shaft. <IMAGE>
