Title: Method of and apparatus for use in reinforcing a piling structure, and a precast concrete pile for use in the method
Inventor: LIN JUEI-TSE
IPC: E02D5/54
Filed: 1981-12-31
Granted: 1985-02-28
Abstract: A method of reinforcing a piling structure by means of an improved precast concrete pile and hydraulic sealing apparatus which comprises the steps of: driving a hollow, precast concrete pile (1) into the ground by means of a pile driver, the pile being formed with thin and frangible portions formed in its peripheral wall, holding in suspension a hydraulic cylinder (8) fitted with a resilient rubber packing (10) thereunder at a desired level within the hollow body of the pile, filling the hydraulic cylinder with oil to cause radial swelling of the rubber packing to such an extent that the deformed rubber closes the clearance between itself and the inner periphery of the pile body and thus defines therewith a sealed hollow space (5b) under the rubber packing, and pumping pressurized mortar through a hose (15) into the sealed hollow space of the pile until the thin and frangible portions of the pile burst open from increasing internal pressure thus enabling the internal mortar to rush out and penetrate the surrounding soil, with the subsequently hardened masses of mortar serving as claws (14) protruding outwardly from within the pile body to prevent settlement of the embedded pile. A plurality of such claws can be formed along the length of the pile by separate injection of mortar into the divided, sealed hollow sections of the pile body from the lower to the higher section. A hollow, precast concrete pile particularly suitable for use in the method has a tapered order, preferably along the length of the pile.

Title: Method and apparatus for sintering refractory walls
Inventor: GENIES BERNARD
IPC: B22D41/00
Filed: 1982-12-09
Granted: 1987-06-25
Abstract: This invention relates to the production of refractory linings. According to the method, the lining formed by refractory materials is heated to a temperature sufficient to cause the sintering of the materials on at least an internal surface of the said lining. To provide this heating action, a flame is produced from a fuel gas and oxygen, within a partially closed volume close to the lining which is to be sintered, and a diluting gas is injected between the flame and the lining, at least during the first part of the rise in temperature. The method is applicable to the sintering of the linings of vessels utilized in metallurgy, in particular of induction furnaces.

Title: Improvements relating to communication over noisy lines
Inventor: CLARK DUNCAN GEORGE DERWENT
IPC: H04L7/04
Filed: 1983-02-25
Granted: 1988-10-06
Abstract: A line network communication system transmits coded data signals on a base band carrier signal and includes a receiver capable of recovering the coded data signals from transmitted signals. The receiver operates in a search mode initially, in which a series of data signals received at (13) is compared, at different relative phases, with a series of coded reference signals using an arrangement of shift registers (12, 15) and an exclusive OR gate (11). 
<??>The reference signals are generated by a coder (1) under the command of a central control unit (3). The control unit monitors the results of comparisons and varies, by means of a shifter circuit (6), the relative phase of compared signals until at least one comparison indicates a degree of correlation exceeding a threshold value. The control unit then operates, in a tracking mode, to verify that said degree of correlation is maintained for a preset number of subsequent comparisons and in dependence on a successful verification enters a locking mode. The control unit maintains a selected phase difference between compared series while the degree of correlation exceeding said threshold value exists.

Title: Row sensing apparatus for a crop harvester
Inventor: WILLIAMS TERRY ARDEN
IPC: A01B69/00
Filed: 1984-08-31
Granted: 1987-06-19
Abstract: A forage harvester (11), pulled via its tongue (16) by a tractor, has dividers (19, 21) between which a crop row (18) is received, and each divider (19, 21) has a row sensing unit (41, 43) bolted to it. The crop row (18) passes between a pair of arms (47, 48) of the unit. An arm (47, 48) is deflected, when the machine is misaligned with the row (18), the arm (47, 48) having an upright pivot shaft (79). The arm (47, 48) carries an actuator plate (95) which closes a switch (145) to trigger a guidance control circuit (45) to steer the harvester by way of a piston and cylinder (33) moving the tongue (16) to return the harvester (11) to alignment with the crop row (18). To enable the harvester (11) to be reversed without the crop row (18) fouling the crop-engaging arms (47, 48) each arm is formed with a trailing portion which curves rearwardly through an angle greater than a right angle toward the divider (19, 21) and then terminates below the divider (19, 21) so that crop can pass smoothly over the arm not only when the harvester is travelling forward, but also when it is reversed.

The compounds of formula I are obtained by the reaction of an aldehyde of formula II with an ylid to give an erythro-diol of formula III which is then cyclised to the required dioxane derivative of formula I. The aldehydes of formula II are obtained from the corresponding lactols of formula IIa, which are themselves obtained with the correct trans-stereochemistry by the inventive process using two selective reductions of a trans-phenylparaconic acid of formula V. The compounds of formula I are useful as therapeutic agents.
