Patent NL-7414276-A (NL)
Title: Heating system using glass plates - has overlapping plates in frame at acute angle and parallel
IPC: F24J3/00
Filed: 1974-11-01
Abstract: The system supplies heat at constant temperature, without using external energy or withdrawing material from or discharging it into the air. It can incorporate glass plates (1) at an acute angle in a frame (3) running in the same direction and largely overlapping each other. These are held apart by other glass plates at the ends (2). The frame is covered with glass plates at the edges, and the direction in which the plates run differs from that in the previous frame. All glass parts can be warmed, heating up each other and delivering the heat to two edges, where the heat developed is concentrated in decreasing area before circulation.

Title: Hand-held hair-drier - has additional short duration booster heating element in circuit with bimetallic heating element
IPC: A45D20/10
Filed: 1980-10-07
Abstract: One of the disadvantages of conventional hand-held hair-driers when compared with the stand-mounted type is that the maximum air temperature is limited by the fact that the hand-held instrument must not become too hot. The new drier has an additional heater, switched on by a push-button, which only operates for about 30 seconds or until a bi-metallic thermostat switches it off. The fan motor (4) is driven by a rectified mains supply, which is switched (10) to the rectifier bridge and series resistor directly (12 closed) or via a diode (11 closed). Likewise the main heater (6) can be switched for direct or rectified supply. The extra heater (20) is switched on by a thumb-operated push-button (21) in the handle of the drier.

Patent NL-8202179-A (NL)
Title: Control circuit for central heating - automatically reduces demanded temp. during winter nights and summer using clock feeding comparator from fixed voltage
IPC: G05D23/24
Filed: 1982-08-12
Abstract: The circuit uses three temp-sensitive resistors as detectors: a PTC type (16) for the heated area temp., an NTC type (4) for the outside air temp., and an NTC type (6), for the radiator water temp. The voltages across the two NTC resistors are summed via buffer amplifiers (1,2) and resistors (9,10) and fed to the one input of a comparator (12). The other input is connected to a resistive chain formed by two preset resistors (15,18) and the PTC resistor (16). The comparator output (19) controls the heating installation. During winter nights and the summer, a clock (14) disconnects (11) the summed input, and feeds the comparator from a fixed voltage; at the same time, an additional preset resistor (17) is introduced in the divider chain, providing a higher input voltage to the comparator (12), so that the temp. must drop to a lower level before the system is switched on.

Title: Environmental kinetic to electrical conversion using magnetic flux - energy from kinetic particles or photon field into electron current in conductor surrounding permanent magnet
IPC: H02N11/00
Filed: 1988-03-09
Abstract: The energy conversion method uses a permanent magnet (11) which is installed in the space within a sec. coil (13) which lies within and concentric with a pref. superconducting prim. winding (12). The axis of magnetisation lies in a plane parallel to the upper and lower boundary planes of the coils (12, 13), which are accommodated between thermally conductive plants (14, 16) of e.g. Cu or Al with outwardly projecting ribs (15, 17) of the same material. Alternating current through the prim. coil (12) generates an alternating magnetic field at right angles to that of the magnet (11). The resultant field traverses the sec. coil (13) and induces a useful voltage in it. Energy drawn from the sec. coil (13) is replaced by heat transfer from the surroundings through the plates (14, 16) and ribs (15, 17) on either side of the structure.
Patent NL-8801441-A (NL)
IPC: H04N7/26
Filed: 1988-06-06
Abstract: A device for reproducing digitally presented video pictures includes a restoration circuit for restoring erroneous picture elements. To this end a reference sub-picture is composed from the erroneous picture elements and non-erroneous picture elements, the erroneous picture elements being completely enclosed by the non-erroneous picture elements. The erroneous picture elements are subsequently replaced by zero picture elements. Each picture element is then considered as a sum of weighted versions of picture elements which form part of a prediction field. The set of prediction coefficients associated with this prediction field is obtained by minimizing a prediction coefficient function. This operation is performed for different prediction fields and the restoration process is continued in known manner, this continuation being based on the prediction field yielding the smallest value for the prediction coefficient function.

Patent NL-9201594-A (NL)
IPC: H04N7/26
Filed: 1992-09-14
Abstract: Known systems based on layered video coding and video decoding code with inadequate efficiency because the new high-resolution picture is predicted by means of the switching means present in the system either on the basis of the preceding high-resolution picture or on the basis of the instantaneous low-resolution picture. According to the invention, designing the switching means for the adjustment of the ratio of the signal representing the preceding high-resolution picture and the signal representing the instantaneous low-resolution picture and for then adding both the adjusted signals achieves a gain of 3 dB in the prediction with the correct ratio, and this results in an improvement in the coding efficiency. <IMAGE>
