Abstract: In the automatic positioning of the end of an underwater flow line, particularly in deep water, on a base, the end of the flow line is lowered to a position adjacent a connecting sleeve. The end of the flow line is connected to a hauling cable extending through the sleeve and a pull is exerted on the cable to draw the end of the flow line into the sleeve. The sleeve is detachably mounted on positioning apparatus mounted on the base and pivotable relative thereto in azimuth and elevation to align with the flow line. When the end of the flow line has been received in the sleeve and locked thereto, the sleeve is positioned on the base, locked thereto and released from the apparatus which is withdrawn.

Abstract: A device for securing an operation panel on an office machine such as a copier or the like where the parts to be engaged between the operation panel and the machine frame are arranged symmetrically relative to a rotating axis of the operation panel. Electrical wiring extending from the interior of the machine to the operation panel are provided with sufficient lengths, so that the operation panel can be secured to the machine frame in either of two positions rotated from one each other through an angle of 180.degree.. The engagement between the operation panel and the machine frame is of a snap or a slide latch type of coupling.

Abstract: A speed change gearbox for agricultural tractors and similar vehicles has an elongate casing rotatably mounting input and output shafts which are coupled by gearing comprising reduction means selectively operable to provide one of a plurality of reduction ratios, and a final gearing stage which serves to set a particular range of ratios. The reduction means includes an epicyclic gear mechanism provided with associated hydraulic control means for selectively controlling movement of various of its elements, and pairs of continuously meshing gears operatively selectable by further hydraulic control means. The arrangement of the hydraulic control means is such that they are all centered on the input shaft which enables the transverse bulk of the gearbox to be minimized.

Abstract: In a coin sorting machine of the type wherein a sorting coil for detecting the characteristics of a coin inserted into the machine is provided along a coin passage and the output signal of the coil is varied to thereby determine whether the inserted coin is true or false when the coin passes by the sorting coil, a coin sorting period is determined by detecting the position of the inserted coin rolling along the coin passage, and the inserted coin is sorted depending on whether or not a predetermined sorting signal is outputted during the coin sorting period.

Abstract: A machine for the manufacture of glass articles by blow moulding comprises a plurality of article-forming assemblies mounted in a circular array on a rotatable carousel. Each assembly has a number of operating means which cooperate to shape a gob of molten glass, first by rough-blanking using a plunger, and then by blow-moulding, into the required article. Control of said operating means is effected by a set of primary control members adjustably positioned in fixed locations around the carousel, and a respective set of carousel-mounted secondary control members associated with each assembly. As the carousel rotates, the secondary control members are moved past and influenced by corresponding ones of the primary control members and, as a result, the operating means of each assembly are appropriately controlled to shape the required article.

Abstract: A process for producing L-valine or L-lysine which comprises aerobically culturing a bacterium belonging to the genus Acinetobacter, which utilizes ethanol and has an ability to produce and accumulate L-valine or L-lysine, in a culture medium in which ethanol is the main carbon source to produce and accumulate L-valine and/or L-lysine and collecting.

Abstract: A method for controlling insects harmful to wood comprising contacting the insect with a composition comprising a carboxylate of the formula: ##STR1## as an active ingredient.

Abstract: A combined well casing spider and elevator is formed of a main body having a downwardly tapered bowl inner wall. The main body has an open end wall having spaced apart recessed flanges on either side of the opening. A gate member is pivotally secured to one of the recess flanges and releasably secured to the other of the recessed flanges to close the open end wall when the gate is in a secured position. The gate member pivots laterally when released to permit the lateral entry of a well casing within the area defined by the bowl inner wall. A circumferential array of casing gripping slips are arranged in opposing pairs for vertical and radial mounting in surface contact with the bowl inner wall, the gripping slips forming a circular hole within the center of the array to receive a well casing. The slips are vertically moveable along the bowl inner wall to effect radial enlargement and contraction of the circular hole formed thereby by upward and downward movement respectively to release and grip the casing.

Abstract: A tracked agricultural tractor in which the frame of the driver's cab is mounted on the tractor body by a suspension including a pair of transverse suspension structures, a pair of rigid transverse support structures and first and second shock absorber means, can be driven at speed over rough ground without a substantial adverse effect on the driver's comfort, since the rolling and pitching oscillations of the cab relative to the tractor body are damped by the shock absorbers, and their amplitudes limited by stop elements acting between the suspension and the cab frame.

Abstract: A tapered, hollow bowl of a well spider fitted to an elongated base member and supporting a circumferential array of well casing gripping slips mounted within the bowl for vertical movement to radially enlarge and contract a circular hole within the center of the slip receiving the well casing is segmented to include a pivotable door which carries at least one of the slips, the door being locked in closed position, but pivoted to open the side of the bowl to permit lateral entry of the well casing through the open door.

Abstract: A rotary fluid pump having a rotor with carbon vanes disposed in a rotor chamber. A cylindrical aluminum sleeve is force fitted into a mating arrangement with the inner peripheral surface of the rotor housing. The aluminum sleeve reduces the friction between the housing and the vanes. The sleeve may be of the same axial length or shorter than the rotor housing. If it is equal end seal plates are employed to provide the necessary expansion gap or end washers are employed at the housing to increase the effective axial length.

Abstract: A photo-curable composition with high covering power provides the coating film with a glossy smooth surface when such composition is exposed firstly to light radiation having wavelengths of from about 350 nm to about 460 nm, and then to light radiation having wavelengths of from about 230 nm to about 400 nm with a specific ratio of the intensity of the former light radiation to the intensity of the latter light radiation.

Abstract: An apparatus for use in monitoring the numbers of a selected species of insect comprising one or more traps into which is put a synthesized pheromone to attract that particular insect. Each trap has a grille comprising a plurality of bars between which is applied a high voltage by means of a high voltage generator, so that when an insect of the selected species tries to enter the trap it touches adjacent bars and is electrocuted by the electric discharge between them. This discharge is detected by a discharge detector connected to the trap and the detector passes a signal to a transmitter which transmits it to a central receiver equipped with a discriminator for ignoring signals other than those from the transmitter and for passing the signals representing discharges to a pulse counter whereby a total of the number of insects trapped in a given time can be obtained at a central station without visiting each trap.

Abstract: A wear resistant rubber hose for transferring fluid containing abrasive material such as crushed stone, coral, etc. comprises an inner surface rubber and a continuous chainshaped filling body having a rigidity which is considerably higher than that of the inner surface rubber embedded directly inside the inner peripheral surface thereof.

Abstract: The invention relates to a tool which incorporates a device insuring the efficient control of a percussive hammer, regardless of the drilling depth.
