Title: Improvements in or relating to manually operable hydraulic actuators
IPC: B01D46/52
Filed: 1961-07-07
Abstract: 962,004. Manipulators. GENERAL MILLS Inc. July 7, 1961 [July 7, 1960], No. 24701/61. Heading B4Q. [Also in Divisions B8 and F1] A manually-operable hydraulic actuator comprises a source 30, Fig. 1, of fluid pressure, a manually-operable member 13 for operating valve means 21, 22 controlling an output actuator 42 for operating jaws 43 of a manipulator used in the atomic industry, and a fluid-operated feel-back actuator 51 sensitive to changes in fluid pressure in the actuator and operatively associated with the control member so as to resist the manual operation of the member and provide a tactile indication of the force exerted by the output actuator. The control member 13 consists of a handle mounted on a pivot 20 on a frame member 10 movably mounted in a base 9. An end 17 of the control member is disposed between the valves 21, 22 which each have an operating mem. ber 26, 68 connected to a poppet 61, 66 urged by a spring 70, 71 into engagement with a seating in the valve. The valve 21 has an inlet 25 connected to an accumulator 31 and the pump 30 and an outlet 40 connected by a pipe 45 to the actuator, the inlet 50 of valve 22 and a chamber 88 of the feel-back actuator 51, the actuator having a diaphragm 83 in mechanical contact by a rod 86 with the part 17 of the control member. A pair of adjustable springs 96, 97 control the neutral position of the control member; the neutral position may be a central position in which both valves 21, 22 are closed and the actuator is hydraulically locked in position. When the control member is moved to raise the end 17, the valve 21 is opened and fluid pressure from the pump passes to pipe 45 and the actuator 42 to close the jaws 43, the pressure in pipe 45, and consequently the actuator, also acting in chamber 88 to urge the diaphragm 83 and rod 86 downwardly and apply a resisting force to the control member. When the control member is moved in the opposite direction, valve 22 is opened and connects the actuator to a return line 56. The feel-back actuator is adjustable along a slot 95 to vary its effect on the control member. Similar arrangements may be used to operate other motions of the actuator, such as rotation of the gripping mechanism. In another embodiment, two pairs of valves are provided, one pair being connected to each end of the actuator so that the actuator is movable hydraulically in both directions. In a further embodiment, the control member 202, Fig. 4, is movable about a pivot 201 and is connected to the movable part 211 of a valve 205 having a port 211 which is normally open to permit fluid pressure from the pump 206 to pass from an inlet 210 to an outlet 222 and reservoir 223. When the control member is moved clockwise, the part 211 closes the port 211 and pressure in a chamber 208 is communicated to the actuator 215 and the chamber of the feed-back actuator 220. The valves may be of the spool type. Other motions of the manipulator may be controlled by similar actuators.

Title: Inertial navigation system error correcting methods
IPC: G01C21/16
Filed: 1966-06-03
Abstract: 1,118,663. Navigation computing. NORTH AMERICAN AVIATION Inc. 3 June, 1966 [3 June, 1965], No. 24934/66. Heading G4G. [Also in Division G1] A gyroscope stabilized inertial navigation system comprises a computer from which output navigation signals are obtained, the computer also being arranged to formulate in differential equation form an augmented navigation system which incorporates the effects of applied correction signals, the computer being further arranged to estimate the correction signals to be applied from the output signals and from position or azimuth reference data obtained intermittently or continuously, the gyroscope drift rates obtained in this way being split into two components, a constant drift rate and a random drift, the applied correction signals thus being related to both these components and not merely to an estimated linear gyro drift. In analysing the system three co-ordinate systems are defined, the true, platform and computer systems. The true and platform systems have the same centre but are displaced by a vector angle #. The computer system has its origin at the computed vehicle system giving a position error 80 relative to the true co-ordinate system. Platform drift is defined by a vector # relating the platform and computer co-ordinate systems. Thus # = # + ##. The # vector has three components representative of the misalignments between the computer and platform co-ordinate systems. In vector rotation this can be given by the differential equation # = V# + # g (1) where # is the time derivative of #, and V is a matrix representative of the velocity of the system relative to inertial space. # represents the drift rate of the platform. If the reference data is obtained from a star tracker having an azimuth a and elevation # then the output equation of the system assuming error angles #α and ## takes the form or more simply y = M 2 (α, #)# where M 2  is the above 2 x 3 matrix. It is desired to estimate the drift rate vector # assuming this to be variable. The random drift rate vector # r  can be represented by the differential equation # r  = H# r  + w (2) where H is a diagonal matrix and w represents a white noise vector. The constant drift rate vector # o  is simply # o  = 0 (3). Combining equations (1), (2) and (3). the augmented system is now obtained as or more simply X = Fx + #w. The output of the augmented system is of the form y = Mx + v. Adding the effect of control to the augmented system equation we get X = Fx + #w + Ju where J is a control distribution matrix and u is the control vector. The optimum control vector is determined by relating the performance index L of the system i.e. positional error with time, to the control vector u by integrating L with respect to u. The optimum control vector is then used to apply corrections to the inertial system and generate the augmented system.

Filed: 1976-06-17
Abstract: The forward movement of a pipe-laying vessel when laying pipe offshore is controlled to maintain the position of the pipe as laid on the sea bed as close as possible to the desired track. The position of the touch down point on the sea bed of the pipeline suspended from the vessel is measured at periodic intervals by driving a survey vessel fitted with an echo location device along the already laid line. The measured position of a touch down point is compared with the desired track and any deviation is computed. Further movements of the pipe-laying vessel are adapted to minimize this deviation.

In the manufacture of jams, jellies, and the like, fruit or vegetable foodstuff containing natural sugar, or to which sugar is added, is passed in a continuous stream through a heating zone at predetermined temperature without agitation so that the rate of passage of every portion of the mixture through the heating zone is that of the overall rate of passage therethrough, and the volume of mixture is adjusted with respect to the rate of flow to maintain each portion of the mixture in the heating zone for a predetermined constant period. Preserves of citrous peel, strawberries, cherries, peaches and pineapple, and jellies of cranberry and grape juices are referred to. With the apparatus of Figs. 1 and 2, fruit juice and sugar, and, if desired, pectin, and also, if the fruit is insufficiently acid, tartaric or citric acid, are continuously fed from containers 17 and 18 into a dissolver 11 in which its a screw conveyer 12, and the contents of the dissolver are heated by a jacket 14 and by coils 13 in the upper portion, maintenance of the volume of mixture suitably to the rate of feed being by adjustment of the height of an outlet pipe 20. Some or all of the evaporation may be effected in the dissolver, water vapour being withdrawn through an outlet 19. From the outlet 20 the mixture passes, either directly by a pipe 22 or by way of an evaporator 21, through a .heater 24 or a filter press 25, or both, to a tank 26. In the tank 26, which is provided with a heating jacket 27, heating coils 28, and alternating lateral baffles 29, the mixture is subjected to heating below boiling temperature for a time sufficient to bring about the desired degree of inversion of the sugar, the volume of the mixture in the tank being regulated by adjustment of the height of an outlet pipe 30. Scum formed during the heating of the mixture may be removed; with the apparatus of Fig. 5, a tank 50 is provided with a scraper assembly 51 eccentrically mounted so that members 53 lift scum and move it to scraper members 55 on a rotating wheel 54, which members transfer the scum through a funnel 57 to a centrifugal separator 58, wherefrom the liquid portion is returned at 59 and the scum portion discharged at 60.
