IPC: A61L9/12
Filed: 2015-05-12
Abstract: De onderhavige uitvinding betreft een inrichting ten behoeve van de beheersbare verdamping van etherische oliën en andere vloeistoffen waarbij gebruik wordt gemaakt van een vloeistofhouder met een uitstroombegrenzer en een vloeistof transport koord welk zich volledig buiten de vloeistofhouder bevindt. De uitstroom van vloeistof uit de vloeistofhouder zal zelfs bij het zonder dop omvallen van de vloeistofhouder nog beperkt zijn dankzij de uitstroombegrenzer.

IPC: G21K1/04
Filed: 2016-10-11
Abstract: An electron beam chopper for forming a bunched beam of electrons, the electron beam chopper comprises a deflector and a blocking member. The deflector is operable to receive an input beam of electrons propagating along a first axis and to alter the direction of the beam of electrons so as to form an output beam of electrons such that the direction of the output beam of electrons varies with time through a range of directions. The blocking member is arranged to block the output beam of electrons when it is in a first sub-range of the range of directions and to allow the output beam of electrons to pass it when it is in a second sub-range of the range of directions so as to form a bunched electron beam. The deflector and the blocking member are arranged such that a rate of change of the direction of the electron beam is at a local minimum when the electron beam is in the second sub-range.

Title: Bending glass plates
IPC: C03B23/031
Filed: 1969-01-23
Abstract: Curved glass plates are produced by bringing complementary bending surfaces in contact with a heated, flat, glass plate to mould the sheet to the curve of these surfaces which have virtually the bending temp. of the glass so that heat exchange during bending is limited to a minimum. Thus, at the end of the bending process, the bent glass plate is virtually at bending temp. throughout its thickness and over its surface. specifically, the bending surfaces are kept at the optimum temp. by periodically heating the bending dies on which they are fitted.

Title: Centrifugal cryogenic refrigerator - with totally enclosed working fluid
IPC: F02C1/10
Filed: 1971-06-14
Abstract: An hermetically sealed cryogenic centrifugal refrigerator of which the compressor is an integral part, which obviates the need for complex mechanical shaft seals and the associated problems of oil-leakage and atmospheric contamination of the working medium. The working fluid is circulated within a closed loop by a process of thermocentrifugal circulation, by internal heat-exchangers, from one expansion stage to the original compression stage, there being two compression/expansion stages arranged symmetrically on either side of a suitable rotor bearing (e.g. gas bearing) interconnected by horiz. integral channels. Compression is achieved by the influence of centrifugal force acting on the gas in channels running radially outwards at 90 degrees from the rotor, and expansion takes place in channels running radially inwards at 90 degrees to the rotor.

Abstract: The system is particularly for use on motor vehicles, and exerts a damping force proportional to the speed of movement of the body. The speed can be determined by measuring the force exerted on it and integrating this in the time. Spring and damper can be mounted in parallel with a power absorber in series with them. The power absorbed by the latter is integrated and the damping force adjusted accordingly. The absorber can emit an electrical signal to an integration unit, and absorber and integrator can be combined in a unit comprising an auxiliary and damper in parallel, the alteration in damper length measuring the integrated force exerted by the unit.
