Title: Photosensitive detector device in magneto=optical memory - has semiconductor body with electrode generating charges in depletion layer which drift to detector
IPC: H01L31/113
Filed: 1976-10-08
Abstract: A photosensitive element and circuit operate in the charge transfer and charge storage mode. There is a relatively wide photosensitive area for the detection or measurement of small photon densities down to the order of 1012 photons per cm2 per second. It is suitable for use as photodetector in a magneto-optical memory system. The sensitive element forms part of a semiconductor substrate of one conductivity type with an electrode layer separated by an isolating layer from it in which mobile charge carriers can be generted by the indident radiation, the whole forming a charge transfer structure in which by application of a bias potential to the electrode layer a depletion layer can be formed. Means are provided to generate a drift field in the depletion layer so that the light-generated electrons move to the edge in the drift field where means are provided to produce a charge accumulation zone to collect the charges and detect their presence.

Title: Loom with false selvedge binders - has protective plates preventing entanglement or soiling of warp and auxiliary threads
IPC: D03D5/00
Filed: 1977-04-22
Abstract: A shuttleless loom having a device for forming a false selvedge with the help of one or more auxiliary threads running in the warp direction, has a protective plate moving with the reed. The plate is arranged in a plane parallel to the warp direction, between the outermost warp threads and the auxiliary threads for the selvedge binder. It extends from the rear side of the dley towards the warp beam, and is anchored by an elastic element to a fixed point on the frame, moving against the pull of this element as the reed beats up. Prodn. overcomes the difficulties arising from having the auxiliary threads at a less tension than those of the warp proper, which results in the auxiliary threads obstructing the shed, whilst they collect fly. The motion of the reed packs this up into lumps which cause difficulties in the changeover leading to yarn breakages.
Patent NL-7804730-A (NL)
Title: Detection method for surface deposits - uses differential heat flow measurement in comparison with reference surface
IPC: G01B7/06
Filed: 1978-05-03
Abstract: The detection and measurement of deposits, such as scale or wax on different types of surfaces, is determined by thermal measurements on a test sample compared with a reference. This procedure is sensitive enough to detect deposits without having to wait until they effect operation of a system. A test and a reference surface are submitted to a fluid environment and are subjected to heat flow in a known relationship. The transfer of heat between the surfaces and their fluid environments is compared. Heat flow is applied differentially to decrease difference in temp. of the fluid. These measurements are then used to determine their effect on deposit formation.

Title: Data logging and processing system - uses personal computer to process outputs of many times of transducer
IPC: G06F17/40
Filed: 1989-03-14
Abstract: The system processes signals produced by a number of sensors, e.g. temp. sensors, pressure transducers, etc. Each signal is fed to the control processor (10), e.g. a personal computer, via an interface unit and signal processor. Each signal source has an associated code generator, which produces a code unique to that sensor. The computer memory holds a number of programs, each of which is suitable for dealing with the signals from a different type of source. Instead of being built into the remote sensors, the code generators may be built into the connectors (12) which plug into the interface unit. @(24pp Dwg.No.1/7)@.

Title: Transponder for EM detection system - can be deactivated using magnetised hand-held roller
IPC: G08B13/24
Filed: 1990-05-31
Abstract: The signal element (1) of the transponder consists of a strip of "soft" magnetic material e.g. iron alloyed with nickel or cobalt. The strip is surrounded by a layer of "hard" magnetic material (5) which has a higher coercivity than the signal element material. The length of the strip is equal to or greater than 150 times the square root of its cross sectional area. In its activated state, the outer layer is demagnetised and the signal element is unsatd. The strip is deactivated by passing a roller, which has alternate north and south magnetic poles on its surface, along the strip. the hard material then causes saturation of the element (1) and changes its harmonic response. @(9pp Dwg.No.3/3)@.

Title: Plant containers with watering system
Inventor: RADONJIC NADA
IPC: A01G27/06
Filed: 1998-09-15
Abstract: The plant container with watering system solves the problem of the constant supply of plants with adequate humidity. The container consists of an upper part (1) for soil also considered the internal or growing flower pot (4) with the plant itself, a lower part (2) containing water and a watering pipe (3), which links both parts supplying the plant with water. The system allows individual control of the supply of humidity to the flower, parallel additive fertilisation, the storing of water for longer periods of time thus demanding less frequent watering, which is basically reduced to occasional filling of the lower part of the container. It offers better conditions for the growth of plants, since water is supplied from beneath, so the upper parts of the soil remains airy. A non-controlled leakage and decanting of excessive water to the surface is prevented, since this may be unpleasant or cause damage (furniture, parquet floor, carpets, marble floors or shelves).
