Patent NL-2031954-A (NL)
Title: Photoelectric coupling device
Inventor: FEI GAN
IPC: G02B6/42
Filed: 2022-05-20
Abstract: The present application discloses a photoelectric coupling device, which includes a Fiber Array (FA) or a Planar Lightwave Circuit (PLC) array, a glass substrate, a glass cover plate, a dioptric focusing lens, a Photoelectric Diode (PD) array, and a heat sink. The glass substrate is arranged on the glass cover plate. The FA or the PLC array is arranged between the glass substrate and the glass cover plate. A front end of each of the glass substrate and the glass cover plate is provided with a first abutting surface, and a rear end of the dioptric focusing lens is provided with a second abutting surface which abuts against the first abutting surface. A total reflection surface is arranged on the dioptric focusing lens, and a spherical array is arranged at the bottom of the dioptric focusing lens. The PD array is mounted on the heat sink. PDs in the PD array are arranged in one-to-one correspondence with focusing spheres in the spherical array. The light output from the FA or the PLC array enters the dioptric focusing lens from the second abutting surface. The light entering the dioptric focusing lens is reflected to the focusing spheres through the total reflection surface. The focusing spheres focus the light to photosensitive surfaces of the PDs, so as to realize the coupling with the PDs. The present application has the advantages of simple structure, convenience in operation, high coupling efficiency, and low loss.

Title: Electromagnetic generation of ultrasonic waves - in specimen undergoing inspection involving reflection of ultrasound involves RF generator
IPC: B06B1/04
Filed: 1976-12-23
Abstract: A system is used for electromagnetic generation of ultrasonic waves in a specimen undergoing inspection involving the detection of reflected ultrasonic waves. A magnet produces a constant magnetic field within the specimen. An emitting coil is connected to a radio frequency generator and mounted near the poles of the magnet thus inducing a radio frequency field in the specimen. A receiving coil is connected to a reciver and mounted near the poles of the magnet. This receives reflected ultrasonic signals from the specimen corresponding to the emitted signal. Two coils are laterally spaced relative to each other. The two coils (8) are mounted near the same pole (1) of the magnet which produces a magnetic field normal to the surface of the speciment (5).

Title: Mfg. reinforced concrete flooring slabs - by pouring on track with partitions and prestressed rods above, then cutting slabs and rods at partitions
IPC: B28B23/04
Filed: 1978-08-18

Patent NL-8001008-A (NL)
IPC: F24S90/00
Filed: 1980-02-19
Abstract: This invention relates to a method of controlling the energy management of a system for catching, accumulating and transferring heat comprising a heat collector and a heat accumulator of the thermally stratified type forming part of a heat recovery circuit adapted to pass a heat transport fluid, said heat accumulator forming furthermore part of a consumer circuit adapted to pass the heat transport fluid. Experiments have now shown that excellent efficiency is obtained by using this method in which the heat capacity flux, that is to say, the mass flux multiplied by the specific heat of the heat transport fluid through the consumer circuit and the mean value thereof during a selectable time interval, is determined or estimated at least by approximation and the heat capacity flux through the heat recovery circuit is adjusted so that the difference between the mean value of the heat capacity flux through the heat recovery circuit during a time interval of the same duration as said selectable time interval and said mean value of the heat capacity current through the consumer circuit is equal to a factor to be selected multiplied by the heat capacity of the heat accumulator, divided by said time interval, said factor lying between 0 and 3. Further the invention relates to a system for carrying out said method.
Patent NL-8002510-A (NL)
IPC: F22B1/18
Filed: 1980-04-29
Abstract: In a counterflow non-contact heat exchanger, tube bundles carry fluid back and forth across a hot gas path. As the fluid in the tubes flows vertically downward the temperature of the fluid rises. As the gas rises in the heat exchanger it loses heat due to the heat exchange process. This means that the temperature profile of a tube bundle will show a greater thermal expansion in the lower tubes. The present invention seeks to provide an efficient and improved support arrangement for heat exchanger tubes to accommodate this phenomenon by supplying a pivotally mounted tube support plate which will rotate and translate slightly from a substantially vertical plane to accommodate thermal expansion. Further, if there are multiple tube bundles, additional tube support plate sections will allow a tube support plate to articulate in sections to accommodate thermal movement.

Abstract: Gas sensor consisting of a housing which is divided into two compartments 3 and 4 by means of a fluid filter 2, e.g. a bed of activated charcoal. Compartment 3 has an iniet channel 5 and contains a first gas-sensitive semiconductor 6, the measuring device. Compartment 4 has an outlet channel 7 and contains a second gas sensitive semiconductor 8, being used as a reference device. The value of the electric resistances of devices 6 and 8 will increase or decrease when the compartments 3 and 4 contain either an oxidising or a reducing gas. The sensor is used in a gas detection system in which an electronic circuit which follows determines the ratio between said resistances and the ratio of the reference device and a reference resistance. These ratios are subsequently compared to certain limiting values, and when these values are exceeded, a detection signal will be produced.

Abstract: The training aid for alpine skiing on snow-free slopes provides the possibility of practising alpine skiing, particularly slalom and giant slalom with a very similar technique to the skiing technique so that the training with this equipment does not represent any inconvenience to move from "preliminary" training to practising on natural snow. The aid is made from a profile (1) featuring two supports (3, 4) looking at opposite sides in front and in the back while on each leg (6, 7) of the supports (3, 4) there is at least one wheel (5) so that the axes (8) of the wheels (5) are at level and that the leg (6, 7) wheel (5) axes (8) of one support (3 or 4) are at an angle (alpha) open towards the centre of the profile (1) or the wheels (5) are on the same side of the profile (1) tangentially on the virtual arch (L). The legs (6, 7) of each support (3, 4) are connected to each other by a distancing mechanism (9) for adjusting the (alpha) angle.
