Patent GB-2064386-A (GB)
Title: Cleaning using mixtures of liquid and abrasive particles
IPC: B24C5/02
Filed: 1980-11-07
Abstract: Cleaning apparatus and method, particularly for the inner surfaces (1) of pipes (2). A conical sheet water jet (11) issues from a vortex chamber (5) and a second conical sheet jet (13) issues from a second vortex chamber (6) in which the water and abrasive have swirled at lesser pressure. The two jets impinge to form a resultant conical jet (16) which strikes and cleans the pipe wall. Guides (27) hold the apparatus within the pipe so that the axes of the pipe and all the jets coincide, and the hoses (8, 10) by which water and abrasive reach the apparatus may also be used to help move the apparatus up and down the pipe. The axial sense of the resultant jet (16) may be such that it exerts a "squeegee" action upon the pipe wall when the apparatus is withdrawn from the pipe by pulling the hoses. <IMAGE>

Title: Sampling circuit
IPC: H03K7/02
Filed: 1980-12-19
Abstract: The sampling circuit comprises a transmission gate P formed by two MOS transistors (T2, T3) and a control circuit formed by N + 1 delay elements (IO to IN). The control circuit delivers a signal H* which is inverted and delayed with respect to the clock signal H and the two signals H and H*) are applied to the two transistors respectively of the transmission gate P so as to produce a conduction path between the input E and the output S when the signals are simultaneously higher than the threshold voltage of the transistors (T2 and T3). The circuit makes it possible to provide for conduction of very short duration, without requiring the generation of sampling pulses. <IMAGE>

Title: Method for metalizing holes in insulating material
IPC: B05D3/12
Filed: 1979-11-16
Abstract: A method for metalizing the surface walls of a printed circuit board (10, 11, 12) through hole to produce an electrically conductive path (15) from one metallic layer (11) of the board through the insulating plate (10) to another metallic layer (12). A drill bit (13) is forced through the board and into a block of soft conductor material (14). While the bit (13) is turning, the conductive cuttings from the block (14) are carried to the hole in the insulating plate (10) and smeared on the wall surface by the bit (13). The smeared conductive material creates an electrically conductive path (15) between two metallic layers (11, 12) of the printed circuit board (10, 11, 12).

Title: Thrust vector control systems for sterrable craft
Inventor: HICKS MALCOLM ANTHONY
IPC: F02K9/88
Filed: 1982-03-15
Abstract: A thrust vector control system for a missile has a centrally placed main valve 1 operated by a solenoid 10, and four secondary valves 6 individually operated by solenoids 12. The solenoids 10 and 12 are sequentially energised so that the four valves 6 are initially held closed and the main valve 1 opened to allow pressurised gas to flow into a chamber 5 of predetermined volume defined between the main valve 1 and the four valves 6. The main valve 1 is then closed and a selected one of the secondary valves 6 opened to allow the predetermined volume of pressurised gas to escape from a nozzle 9, thereby imparting a small reactive thrust to the missile which is used for fine steering adjustment. <IMAGE>

Title: Combined cycle apparatus for synthesis gas production
Inventor: STAHL CHARLES ROBERT
IPC: C01B3/38
Filed: 1982-11-17
Abstract: Hydrocarbon fuel, oxygen and steam are partially burned in a combustor 13 to produce a high temperature and cause reaction of the remainder. The products of combustion and reaction, after passing through a gas turbine 14 and subsequently through a heat exchanger 70 to produce steam are processed through a condenser 76 to remove the liquid component. In one embodiment, Fig. 3 (not shown), the gases are thereafter delivered through a compressor (102) and a cooling tank (104) to provide hydrogen and carbon monoxide which are reacted in a process reactor (110) to produce useful hydrocarbon products, an example of which is methanol. The steam produced at the exchanger 70 is used to drive a steam turbine 60. Electric power is produced by a generator 40 driven by the gas and steam turbines. The generator output is used to operate all of the motive means which process gases in the cycle. Excess electric power and steam are available for cogeneration use. <IMAGE>

Title: Silica-supported chromium oxide-containing olefin polymerization catalysts
Inventor: WITT DONALD REINHOLD
IPC: C08F4/74
Filed: 1983-01-20
Abstract: A silica hydrogel containing chromium is aged under conditions such that at least a portion of the aging is carried out at a pH within the range of 7 to 9. The resulting hydrogel is converted to a xerogel by treating with a volatile organic liquid. The desired pH can be obtained either by adding a basic material such as ammonia to the hydrogel prior to or during the aging process or by using a chromium component which inherently gives a higher pH and/or resists the natural tendency for the pH to decrease during aging. An example of such a chromium compound is chloropentammine chromium (III) chloride. The resulting catalyst on activation is particularly suitable for olefin polymerization under conditions where higher melt flow polymer is desired.
