Patent GB-2194587-A (GB)
Title: Variable actuator for a valve
Inventor: CHARLTON STEPHEN JOHN
IPC: F01L9/10
Filed: 1987-06-12
Abstract: A valve actuator such as an hydraulic tappet. In one embodiment the tappet comprises a cylinder (16) which defines by means of a central wall (17), upper and lower chambers (18, 19). These have respective pistons (20 and 21). Piston (20) is connected to an actuator rod (13) of a valve (11), whilst piston (21) rides on a cam (23). The central wall is formed with two flow paths (24 and 25). The first allows oil to flow from the chamber (19) to the chamber (18) during upward movement of the piston (21) and hence the cam can cause lifting movement of the piston (20) and opening of the valve (11). As the cam (23) falls away the valve (11) closes under the action of spring (14) which results in downward movement of the upper piston (20). The rate of this return is dictated by the rate at which oil can flow through the passage (25) which can be variably restricted by control element (27). Thus, by adjustment of the control element (27) the rate of closing of the valve (11) can be varied. Other embodiments are described but in each the return movement of the upper piston (20) is variably damped.

Patent GB-882083-A (GB)
Abstract: 882,083. Photogrammetric plotting apparatus. NISTRI, U. Feb. 24, 1958 [March 2, 1957] No. 5907/58. Class 97(1). Apparatus of the projection type has lighting projectors movable on parallelogram linkages to illuminate only the parts of the transparencies in use, both linkages being coupled for movement by the plotting unit through a single rod. In the form shown each of the projectors A, B is rotatable about the optical axis and also about axes perpendicular to and coincident with the axis of a rod 3 projecting from a member which is adjustable in the y, z and x co-ordinate directions, the latter lying along the supporting rod 1, the two systems being oppositely adjustable in this direction by oppositely handed threads on a rod 18 rotatable by a knob 19. The plotting unit carrying the marker screen 28 is coupled at 29 to a telescopic rod 27 connected to one of two forked members 26 pivoted on the rod 15 and coupled together and to a member having a projecting rod 25 which is thus kept parallel to the rod 27. The rod 25 slides in a cardan joint on a member 20 slidable on rods 22 connecting members 23 slidable in turn on rods 24. A member 21 is joined to the member 20. The lighting projectors 6 are carried on parallelogram linkages 5, carried on rods 4 secured to the members 2 and operated by projecting links 7 coupled through cardan joints 8 and adjusting screws to the member 21. Screws 10, operated by knobs 12, provide adjustment in the y direction and screws 9 in the x direction. The latter may be operated simultaneously by knobs 11 or independently by knobs 13. The end of the rod 27 is secured in one or other of the members 26 in accordance with the disposition of the plotting unit on the table.

Title: Blood pressure monitoring method and apparatus
Inventor: ECKERLE JOSEPH S
IPC: G06F17/00
Filed: 1988-09-12
Abstract: Intraarterial blood pressure is measured noninvasively by an electromechanical transducer (22) that includes an array of transducer elements (22-1) through (22-19). The transducer extends across an artery (24) with transducer elements at the ends of the array extending beyond opposite edges of the artery. A set of diastolic and/or systolic pressure and pulse amplitude values is obtained from the outputs from the transducer elements, which values are stored in computer (62). Information concerning the subject related to the diameter of the underlying artery including, for example, the subject's age, weight, arm and wrist diameter also is entered into computer (62) through keyboard (64), from which information an estimation of the diameter of the underlying artery is obtained. Using the set of pulse amplitude values, a transducer element at the center of a search area located substantially at the center of the artery is identified. A center of gravity, a two humps and/or a curve fitting method may be used to identify the transducer element at the center of the search area. A group of transducer elements that overlies the artery of estimated diameter then is identified. Using outputs from only said group of transducer elements, one transducer element having a local minimum of one of the diastolic and systolic pressures, relative to the transducer at the center of the search area, is identified, which transducer element is selected for monitoring blood pressure.

Title: Removing a coating from a coated pipe
Inventor: COOPER BRYAN JOHN
IPC: B08B7/00
Filed: 1989-01-31
Abstract: In order to remove the coating from a pipe 16 coated with a material which is different from the material of the pipe, the coated pipe 16 is placed in a thermally insulated housing 2 and is subjected to a low temperature treatment by passing low temperature gas or liquid along a spray bar 20 extending with the pipe 16 such that the bond between the coating 17 and the pipe 16 is destroyed. Such a method can be used in the removal of a coating of, for example, pvc, bitumen or rubberised solution from a metal pipe with complete reliability. Wire brushes (30, Fig 4) or a curved T-shaped cutter (31, Fig 5) may supplement low temperature treatment. <IMAGE>
