Title: A graphene membrane optical fiber f-p resonator with photothermal stress regulation and control, manufacturing method thereof
Inventor: ZIANG LI
IPC: G02B/
Filed: 2020-12-30
Abstract: The present invention discloses a graphene membrane fiber F-P resonator with photothermal stress regulation and a manufacturing method thereof. The resonator takes graphene membrane as a resonant sensitive element, and the laser excitation end and the detection end adopt a structure in which the quartz capillary is combined with the ceramic ferrule. The method comprises: 1) welding the single-mode fiber and the quartz capillary with a fiber fusion splicer, and cutting the quartz capillary to a certain length with a fiber ultrasonic cutting knife, to form an initial cavity length of the Fabry-Perot interference cavity; 2) assembling the cut single-mode fiber-quartz capillary structure and the ceramic ferrule, and transferring the graphene membrane on the end surface of the ferrule; 3) fixing and aligning the regulating end structure assembled from the multi-mode fiber and the ceramic ferrule with the excitation end through a ceramic bushing, and 4) through adjusting distance between the multi-mode fiber end face and the graphene membrane, bonding and encapsulating the tail part of the ceramic ferrule and the fiber with epoxy resin. The present invention has the advantages of small structural size and adjustable membrane stress and resonant frequency.

Patent NL-7807784-A (NL)
IPC: F16J15/46
Filed: 1978-07-20
Abstract: A connector for connecting lengths of metal tubing such as used for air-conditioning or central heating ducts, comprises a cylindrical end part for insertion into an open end of the tubing. In order to provide a seal between the connector and the tubing the connector has a recess containing a hollow, flexible sealing ring into which fluid can be injected to expand the ring. In order to ensure an adequate seal both before and after expansion of the sealing ring the latter has outwardly projecting sealing flanges which, before expansion of the sealing ring, make a seal due to their own inherent resilience and/or the resilience of the sealing ring, and, after expansion of the sealing ring, form a seal under compression. In one embodiment of the connector a sealing flange is adapted to fold over and lie between the respective faces of the connector and the tubing to prevent metal to metal contact between them.

Title: Toothed feed cylinder of fibre carding machine - has dust scraper blade with compressed air supply against entrained boundary air flow
IPC: D01G15/34
Filed: 1980-06-24
Abstract: The arrangement is intended for removing dust and dirt etc. from fibres whilst these are moved on the teeth of a feeding or fibre preloosening cylinder upstream of a carding drum. The dust particles are removed by at least one blade whose pointed edge is directed at an angle towards the periphery of the cylinder against its direction of rotation. Behind the edge , compressed air is fed into the space between the blade and the cylinder at a pressure which is such that, at the edge, the boundary air flow entrained by the cylinder is decelerated. Sepd. dust particles are removed by suction in the usual way. Used for removing dust etc. from fibres being fed to a carding drum in a carding machine. The arrangement provides a more effective cleaning action than is achievable by the usual scraper blade without air pressure supply.

Title: Combined windmill and heat pump - has vane moving sail to wind to power pump compressor control circuits
IPC: F03D9/00
Filed: 1981-07-17
Abstract: The compressor and auxiliary devices on this heat pump are driven by power supplied by a windmill. The propeller-type sail (1) is mounted on a casing (16,15) on top of a tower (21). A vane (7) is used to move the sail towards the wind direction with the aid of electronically-driven (9) rotation gearing (15). The sail rotates, driving an asynchronous generator (3) and the compressor (4). The heat pump medium is taken from the expansion chamber (6) and pumped down via a flexible pipe (10) to the heat exchanger (12) inside a water jacket (14) at the base of the tower. The medium condenses, supplying its latent energy to the water, and is returned to the expansion chamber (6).

Title: Mercury barometer which can lie horizontally without vacuum loss - has end of capillary in reservoir bent into protrusion at back of scale plate
IPC: G01L7/20
Filed: 1985-05-24
Abstract: The capillary tube (5) at the base of the column is bent through 90 deg. so that its open end is in a protrusion (6) at the rear and bottom of the mercury reservoir (1). The reservoir is sealed (3) by a cap which retains the mercury but allows atmospheric pressure to reach surface of the mercury (2). If the barometer is laid flat, so that the back plate (4) is horizontal, the end of the capillary tube is still immersed, thus stopping air from spoiling the vacuum in the column. When hung on a wall or lying down, the reservoir is protected by stand-off pins on the back of the plate (4).
