Title: Improvements in or relating to pile driving
Inventor: LAM HENG BENG
IPC: E02D13/04
Filed: 1986-10-13
Abstract: Pile sections (13) are driven into the ground (5) by a ram (8) driven by a hydraulic cylinder (37). The section (13) is guided through a tubular guide (2) which prevents bending of the section and which has a detachable end portion (4) which is embedded in the ground. The guide (2) and cylinder (37) are vertically slideable on a rail (3) and can be raised and lowered by a further hydraulic ram (39). Each section is driven in a single stroke and further pile sections are added through a door (11) in the side of the guide (2) between successive strokes. The apparatus is transportable on a tracked vehicle (41). By supporting the pile (13) in the guide (2) during driving it is possible to use pile sections of small diameter which are light and easy to handle. The pile sections (13) are connected using a tubular metal joint member (14, Fig. 3), and have reduced end sections whereby, when fitted, the connectors outer surface is flush with that of the pile. <IMAGE>

Title: Controlling the stroke of a press or shearing machine
Inventor: NAITO KINSHIRO
IPC: B21D28/20
Filed: 1987-02-05
Abstract: To reduce the noise and/or vibration generated by a press, e.g. a turret punch press, or shearing machine theoretical values for the stroke velocity of a ram are calculated, the theoretical values being those velocities at which the machine, in use, generates vibration and/or noise equal to or below an allowable value. The actual stroke velocity is controlled e.g. by a CAD/CAM device according to the position of the ram sensed by a transducer such that it substantially corresponds to the calculated theoretical values. The control may be closed loop with velocity or acceleration feedback. The theoretical values may be empirically determined from such factors as quality, workpiece thickness, shape and process type, or may be learnt from measurements of time taken during a shearing process.

Title: Question-and-answer board games
Inventor: HOWORTH PETER
IPC: A63F9/18
Filed: 1987-03-05
Abstract: A board game comprises a board which simulates the appearance of a crossword puzzle, and a display device for sequentially displaying a number of questions and their associated answers. The board has a number of distinctively marked squares - e.g. squares marked with coloured patches. The object of the game is to move a token which is initially placed at the centre of the board to one of the distinctively marked squares by throwing a dice to determine the number of squares which the playing token may be used, and then successfully answering the next question displayed by the display device in order to secure a further opportunity to move the token a distance determined by a further throw of the dice. The display device displays a clue at window (8) and the correctness of the answer can be verified by raising shutter (10) at window (9). The next question can be obtained by rotation of wheel (7). <IMAGE>

Title: Gas turbine engine fuel system
Inventor: MILES BARRY DONALD
IPC: F02C7/232
Filed: 1989-02-07
Abstract: In an aircraft jet engine, on main engine shutdown unburned fuel in the main engine combustion system (124) is back purged into the main fuel metering unit (116) and is sprayed from the metering unit into the engine bypass duct (160) from whence it is subsequently expelled. This does away with the need for a separate onboard drainage tank for unburned fuel remaining in the engine on engine shutdown. Fuel is supplied from a tank 110 via a pump 112, and a gear pump 114, a line 103 feeding fuel via a pump 118, switch valve 120 and metering unit 122 to an afterburner system 126. <IMAGE>

Patent GB-2224041-A (GB)
Title: Galvanising bath
Inventor: FARNSWORTH VERDUN HILDRETH
IPC: C22C18/04
Filed: 1989-09-01
Abstract: A galvanising bath composition comprises about 5ppm to about 100ppm by weight of aluminium and rare earth elements in an amount greater than zero and not exceeding about 5ppm. The source of the rare earth metals may be mischmetal. The bath may also include lead, nickel, tin cadmium, copper, antimony, magnesium, nickel and silicon. Also envisaged is a method of maintaining this galvanising bath composition in which aluminium and rare earth materials are added to the bath at a ratio greater than the ratio of the selected concentrations of rare earth materials and aluminium in the galvanising bath composition, since the rare earth elements are lost from the bath at a faster rate than the aluminium.
