Title: Method of Grouting an Annular Passage
IPC: E02B17/00
Filed: 1979-07-12
Abstract: A method of grouting an annular passage includes sealing the annular passage at a first location, injecting gas into the passage to purge it of material, sealing the passage at a second location, venting the sealed passageway and injecting grouting material therein. Air is the preferred gas and the passage is preferably vented to atmospheric pressure. The preferred means of sealing the passage is by use of inflatable packers 40. The method is particularly useful for grouting the annular passage between a tubular oil rig leg and a bile driven therethrough. <IMAGE>

Title: Wiper blade harness
IPC: B60S1/38
Filed: 1980-01-22
Abstract: A wiper blade harness has a supporting yoke (1) pivotally connected to a supported yoke with side walls (16, 17) by a link (3) having resilient legs (10, 11, 12, 13).

Title: Numerical Control System
IPC: G05B19/41
Filed: 1980-02-15
Abstract: An on-line numerical control system for the positioning of a cylindrical machine tool (1) during machining, which calculates the path for the tool to travel along and eliminates over-cutting by compensating for the size of the tool. If the workpiece is to be cut along desired contours P1 and P2 which may be straight or curved, then the control system first constructs compensated contours S1'E1' and S2'E2', which are parallel to P1 and P2 respectively and separated from them by a distance equal to the tool radius r. It then calculates the point of intersection Q' of S1'E1' and S2'E2' and instructs the tool to follow P1' as far as Q', thus cutting the contour P1, and then to follow P2, thus cutting the contour P2. By allowing the tool to travel along one contour only as far as the intersection, over-cutting is avoided. <IMAGE>

Title: Fuel economy monitoring switch
IPC: H01H35/38
Filed: 1980-02-19
Abstract: A flexible piston 18 divides the interior of a casing 17 into two chambers 19 and 20, the chamber 19 communicating with a carburettor venturi (12, Fig. 1) of an engine via a port 21. When the gas pressure at the venturi is either constant or decreasing, the flexible piston 18 acting as a one-way valve maintains the pressure in chamber 20 equal to that in chamber 19 so that an electrical contact 24 movable with the piston is held by a spring 25 in engagement with a fixed contact 22. As soon as the gas pressure at the venturi increases, the increased pressure in chamber 19 moves the piston 18 and thereby disengages contact 24 from contact 22, thereby generating an electrical signal to indicate that the engine is not being operated in an economic manner. <IMAGE>

This substance is believed to be a homogeneous polymer of protein and sugars, containing phosphoric acid. This substance has an excellent interferon inducing activity and low toxicity and is significantly active against various viruses. The interferon inducer may be produced by extracting a substance having interferon inducing activity from the tissue of a plant of the genus Perilla of the family Labiatae or a variant thereof containing said active substance and recovering the active substance from the extract thereby obtained. Preferably, the extraction may be effected with water and the recovery may be effected by ultrafiltration.

Title: Device for preventing deposit of sediments in uptake tubes of an evaporator
IPC: C02F1/04
Filed: 1980-12-18
Abstract: During evaporation for the production of soft water from raw salt water or briny water, by using uptake tubes heated from outside, the inner walls of the tubes are covered with a substantial amount of sediments. The elimination of such a layer of sediments takes place generally by stopping the evaporator and by mechanically cleaning the different tubes. It is also known to scrape the deposits during operation of the evaporator, which leads to the destruction of the tubes. Further, the cross section area for the passage of fluid is substantially narrowed. According to the invention, it is proposed to actuate, in all the tubes (4) during operation of the evaporator, spiral springs (22) which extend along the tubes; these springs have a negligible influence on the tube walls and eliminate the sediments by means of the turbulence generated. <IMAGE>

Abstract: A hydraulic rotation actuator for indexing comprises a relieving member and rotation actuating member which are sleeved on to a heavy rigid shaft 1 mounted on a machine slide support with the relieving member being positioned below the rotation actuating member. The rotation actuating member has a housing which receives an arc-shaped solid rotary member 22 and a vane-like stationary barrier 23 to form two variable volume fluid chambers e & f and the rotational power thereof is transmitted from the rotary member 22 by means of a joint bolt 25 which will join with a rotatable shell body of the relieving member. This shell body receives upwardly and downwardly movable sleeve bodies 33 & 34 which have an annular groove adjacent to the shaft to form an annular chamber in which a rigid fixed rim 37 is sleeved onto the shaft 1 to divide the chamber into an upper and lower variable volume chambers a & b for the flow of the hydraulic fluid. The shaft has four longitudinal passages A, B, C, D respectively communicated with chambers a, b, e, f of the rotation actuating member and relieving member. By operating a hydraulic pump the fluid enters and flows in the chambers a, b, e, f and passages A, B, C, D, relieving the turret 4 from mounting on the slide support and rotating it for indexing. <IMAGE>

Title: Thermal ink jet printer
Inventor: VAUGHT JOHN L
IPC: B41J2/05
Filed: 1982-06-18
Abstract: An ink-on-demand ink jet printing device is disclosed typically having an ink-containing capillary with an orifice for ejecting ink, and an ink heating mechanism 16 in close proximity to the orifice. In operation, the ink heating mechanism is quickly heated, transferring a significant amount of energy to the ink, thereby vaporizing a small portion of the ink and producing a bubble 12 in the capillary. This in turn creates a pressure wave which propels an ink droplet from the orifice onto a closeby writing surface. By controlling the energy transfer to the ink, the bubble quickly collapses before any ink vapor can escape from the orifice. <IMAGE>
