Title: Spooling and installing trace-heated pipelines of pipe-in-pipe configuration
Inventor: CHRISTOPHER JAMES WORSLEY
IPC: F16L59/16
Filed: 2019-12-18
Abstract: A transition section disposed between two electrically trace-heated Pipe-in-Pipe pipelines connected end-to-end, the transition section comprising: an inner pipe, an outer pipe and an annulus between them. The annulus contains heating cables that extend longitudinally between annuli of the pipelines and longitudinally-spaced seals that, when deactivated, allow fluid communication between the annuli of the pipelines and, when activated, isolate the annuli of the pipelines from each other. Longitudinally-spaced blocking plates close the lumen of the inner pipe and define an inner chamber between them. Longitudinally-spaced openings penetrate a wall of the inner pipe at locations longitudinally inboard of the blocking plates and the seals to effect fluid communication between the annulus of the transition section and the inner chamber and also define a diversion path for the heating cables that extends from the annulus of the transition section to the inner chamber and back to the annulus of the transition section. Embodiments include a method comprising drawing down a partial vacuum in annuli of the pipelines when the annuli are in mutual fluid communication via an inner chamber in a radially inner pipe of the transition section, which inner chamber is isolated from radially inner pipes of the pipelines.

Title: Scroll pump
Inventor: ALAN ERNEST KINNAIRD HOLBROOK
IPC: F04C18/02
Filed: 2022-03-30
Abstract: A non-contacting scroll pump 100, with a scroll 130 which has a base 132, and a spiral wall 134 extending perpendicularly from the base. Also, a recess (132a, fig 5) within the base, a drive shaft 140, and annular bearing 160a for supporting and facilitating rotation. The annular bearing is placed in the recess with an interference fit, which causes deformation of the scroll. A clamping assembly (200, fig. 5) is arranged to apply a force to the base of the orbiting scroll to counteract the misshape caused by the interference fit, which may cause the base to be slightly convex rather than flat. The clamping assembly may include a ring (200, fig. 5), a spring (210, fig. 5) and multiple spacers (220, fig. 5). A bearing cover (230, fig. 5) may be over the recess and the spring can be located between the ring and the cover. The spacers may allow a set a load to be applied by the spring. The clamping ring may clamp onto the bearing and the base to prevent the bearing moving out of the recess. The drive shaft may extend through the scroll. The pump may be used as a vacuum pump in an array of pumps and to pump liquid.

Title: A tube for conveying a fluid
Inventor: Benjamin Jeremy Walsh
IPC: G01P13/00
Filed: 2022-04-06
Abstract: A tube 10 for conveying a fluid comprises a first passage 12 and a second passage 14. A pressure sensor connection point 16 is provided through a wall of the second passage. A valve 20 is in an open condition when a fluid flow through the tube in is a first direction 22 and in a closed condition (Figure 2) when the fluid flows in the opposite direction 24. The pressure sensor connection point is upstream of the valve when the fluid flow is in the first direction, and downstream of the valve when the fluid flow is in the second direction. When the valve is open fluid is conveyed via the first and second passages but when closed the fluid flows only through the second passage. This results in a difference in measured pressure in the two directions which can be used to indicate the direction of flow. The passages may be circular and concentric, or may be semi-circular in cross section and together form a circular tube (Figure 8). The second passage may include a restriction plate or an expansion chamber. The tube may be part of an obstructive sleep apnoea device.

Title: Hybrid magnetic source magnetic lead screw having high positioning precision, and multi-harmonic collaborative modulation method therefor
Inventor: ZHIJIAN LING
IPC: H02K49/10
Filed: 2021-05-25
Abstract: A hybrid magnetic source magnetic lead screw having a high positioning precision, and a multi-harmonic collaborative modulation method therefor. The magnetic lead screw comprises a magnetic nut and a magnetic screw rod, which are coaxially arranged. According to the characteristics of a spiral structure, a new effective harmonic order is introduced by means of spatial matching between a permanent magnet and a magnetic modulation module, thus satisfying not only a modulation mechanism in a linear direction, but also satisfying a modulation mechanism in a circumferential direction, such that multi-harmonic collaborative modulation is achieved. An excitation winding is wound inside the magnetic modulation module, so that an air-gap magnetic field of the magnetic lead screw is adjustable, thereby improving the positioning precision. In the hybrid magnetic source magnetic lead screw having a high positioning precision, on the premise of ensuring high reliability and high thrust density, the defects of an existing magnetic lead screw such as single modulation of a magnetic field, large magnetic flux leakage and insufficient positioning precision are overcome.
