  • Publication number: 20230323877
    Abstract: A method of measuring fluid flow in a system includes providing a fluid supply assembly which includes a fluid supply supplying fluid, a dispensing valve from which the fluid is dispensed, a dispensing line connecting the fluid supply to the dispensing valve, a gear pump including a motor and a gear being rotated by the motor to provide a flow of fluid from the fluid supply to the dispensing line, a revolution counter counting a number of revolutions of an element of the gear pump, a pressure transducer coupled to the dispensing line sensing pressure in the system, and a controller including a processor and a memory to control the system. The method further includes directing fluid from the fluid supply, rotating the gear to provide the flow of fluid from the fluid supply to the dispensing line, and providing a calibration process by modulating the gear pump.

  • Patent number: 9078249
    Abstract: The invention relates to a carrier link of a conveyor chain intended to convey hanging product carriers, which comprises two parallel walls connected by a partition wall and an opening in which a chain lock is positioned, where the chain lock can assume an open state and a closed state, and where the chain lock comprises two locking arms, each with a locking lug, where the locking lugs are intended to secure an object in the central opening such that the product carrier bears against the two locking lugs when the product carrier is conveyed hanging from the carrier link. The invention further relates to a conveyor chain comprising a plurality of carrier links. The aim of the invention is to obtain a more secure carrier link which permits a controlled and traceable flow and which additionally has a higher loading capacity.

  • Patent number: 5568005
    Abstract: The Acoustic Magnetic Field Power Generator uses an acoustic signal focused into a permanent magnet to stimulate the nuclear structure of the magnet to cause the magnetic field of the permanent magnet to move or oscillate. This effect can be used to tap power from the oscillating magnetic field by putting a coil of wire in the oscillating field. When an alternating current signal generator is connected simultaneously to an acoustic transducer and a stimulating coil; whereby, both the acoustic transducer and the stimulating coil are located within the magnetic field of the magnet, the acoustic signal enhances the stimulating effect to the permanent magnet transformer. The acoustic transducer can be any acoustic generation device such as a piezoelectric, magnetostictive, or other acoustic transducer. The combined effect of the acoustic signal and the stimulating coil increases the efficiency of permanent magnet induction transformers.

  • Patent number: 5189934
    Abstract: Arrangement for production of sections cut out from a material web (18), such as sections for articles of clothing. It comprises a carrier element (19) with a deposit surface (17) for the material web (18), an automatic cutter (16) which is displaceable over the cutting member (70; 77) is supported by the slide arrangement. The cutting member is moved by means of a computer program along the intended contours of the sections which are to be cut out. The carrier element (19), which can be a conveyor belt, is of a material which is elastically compressible. The material, by virtue of its elasticity, tends to form a main plane in which, as a result of the compressibility of the material, depressions can be formed by exerting a force on the material, for example by pressing-down of bottom parts of the cutting and picking members.
