Title: Pipe placement with pit forwarding in water-laden ground - involves pressing cutter shoe through cleared opening in pit end concrete walling
IPC: E02D29/05
Filed: 1981-07-22
Abstract: Excavation of the pit is effected on attaining groundwater level (6), with water supplied to maintain this in the pit (1), in a process for making ducts with work shafts or pits by pressing forward in ground carrying water. A watertight concrete bottom (4) is made, using cement which sets under water. Water in the pit is pumped out, when this has set. The bottom is filled with concrete between pile walls (2), to form the pressing vat (8). An end wall of concrete (10) is constructed at the end of the pit in the direction (9) of forwarding duct pipes. This has an approach opening (11), and an annular peripheral seal (12) of elastic material. Pile wall boards (3) are raised above the approach opening, far enough for a sealed cutting shoe (13) to be pressed through it in front of the length of pipe.

Title: Fire-safe valve actuator - has actuator with bolted bonnet valve and exterior shroud supporting housing
Inventor: BRUTON BILLY R
IPC: F16K31/126
Filed: 1981-08-24
Abstract: The fire-safe valve actuator cooperates with a bolted bonnet valve to define a bolt chamber with an exterior shroud supporting the actuator housing and providing an imperfect barrier to prevent an external fire from coming into direct contact with the bolts or studs and nuts that connect the bonnet to the valve body. The bolt chamber may also be filled with an insulation material. The actuator may have a return spring connected to the actuator stem through a bearing so that the winding and unwinding of the spring does not result in torque being applied to the actuator stem. Any diaphragm in the actuator can be connected to the actuator stem by a bearing so that rotation of the stem will not impart torque to the diaphragm. A stop can be provided limiting outward movement of the stem under the influence of the spring.

The plate edge is aligned with the selected number, and is turned until the boss engages in a socket, a cut being made each time this happens.
Patent FR-2501100-A1 (FR)
Inventor: EKLUND URBAN
IPC: B27B1/00
Filed: 1981-12-23
Abstract: A surface-reducing and sawing unit for working tapering trunks (10) possesses two reducing discs (11, 12) which can each be moved independently outwards from the centre line (CL) of the unit by an associated positioning device (31, 32) when, in an electronic evaluation and control unit (100), as a result of data fed in about the particular trunk, it is calculated that the production of a useable additional outer board (16', 17) is thereby made possible. Otherwise, no outward movement takes place, and the entire wood, which would otherwise be sawn up into outer boards, is immediately comminuted to form chips. The invention is suitable for use in saw mills.

Title: White oil prodn. from lubricating oil stocks - by hydrocracking and three-stage hydrogenation
Inventor: EVERETT GARY LEE
IPC: C10G45/10
Filed: 1982-01-05
Abstract: Prodn. of white mineral oils is carried out by (a) hydrocracking a mineral oil feedstock of lubricating viscosity to increase its VI; (b) hydrogenating the hydrocracked oil in the presence of a S-resistant non-precious-metal catalyst to produce a lubricant base stock with an aromatics content above 3 wt.%; (c) hydrogenating at least a fraction of the base stock in the presence of a S-resistant non-precious-metal catalyst to reduce its aromatics content; and (d) subjecting the prod. to selective hydrogenation in the presence of a precious-metal catalyst. The process is esp. useful for producing food-grade white oils. It is capable of giving high yields of such oils having a high VI (at least 100) and a 100 deg.F viscosity of more than 500 SUS.

Title: Dishwasher with water guidance towards upper rack - uses conical and semi-toroidal deflectors preventing formation of froth and utilises water not directed towards spray nozzles
Inventor: CRIVELLO DARIO
IPC: A47L15/23
Filed: 1982-03-26
Abstract: Part of the water introduced via a supply pipe (2) enters a lower rotary collector (4), and the remainder forms a jet through a pipe (20) and Venturi tube (11) into an upper rotary collector (10). The net pressure on the lower collector (4) is downward, and some water flowing from the gap between it and its support (3) is redirected upward by a lower deflector (7) to participate in the washing operation. The slope of the deflector (7) can be chosen to concentrate the upward jet into a precise region of the rack for more efficient washing. A cone of water splashing from the walls of the Venturi pipe (11) is redirected upward by a semi-toroidal groove deflector (18). The arrangement is adapted for a dishwasher.
