Patent NL-6800611-A (NL)
IPC: B32B27/00
Filed: 1968-01-15
Abstract: 1,192,981. Packaging. WELDOTRON CORP. 14 June, 1967 [3 March, 1967], No. 27409/67. Heading B8C. [Also in Division B5] In packaging articles between opposed sheets, electrostatic force is used to force the sheets, one of which may be heated, into contact about the articles, the force being created by passing the sheets between electrodes, one of which is shaped to locally ionize the atmosphere and produce a charge on the adjacent sheet. The electrodes shown consist of a flat plate opposing an oppositely charged series of points mounted on a plate or a grid of tubes. Electrostatic force is also used to guide sheets in web form to the packaging position. In one form, a radiant heater 16 heats a sheet 24 held in a frame 26, the heat radiating between tubes from which extend ionizing points 30. A card 22 bearing articles 20 to be packaged, rests on a charged plate 10. The frame descends and the electrostatic charge causes the sheet 24 to embrace the articles and adhere to the card. The sheet or card may be adhesive coated or otherwise rendered adhesive. In a continuously operating apparatus, Fig. 3 (not shown), cards with articles on them are advanced by a conveyer to a position where a cover web is laid upon them. The cover web descends between radiant heaters and then between a pair of electrodes which produce a guiding charge as the web turns to lay along the cards. The conveyer carries the assembly between electrodes similar to those of Fig. 1, arranged above and below the upper run. The cards may be replaced by a continuous web. In another embodiment, a continuous web of card 102 having article receiving perforations, is laminated with a bottom web, passing between heaters 116, 118 and guiding electrodes 120, 122, by further electrodes 126, 128. A cover web 134 is applied as in the last described arrangement, after articles have been placed in the perforations. In a further device, Fig. 6 (not shown), electrodes cause a heated web to conform to hollow moulds forming a conveyer chain, the recesses so formed being filled and a cover web applied as before.

Title: Register achieving after stoppage on rotary-screen printing mach - by reversing rotary-screen and print
IPC: B41F15/08
Filed: 1973-06-27
Abstract: Material to be printed is fed from a reel in continuous stream. This is converted into discontinuous sheet feeding of the web through an accumulator or festoon from which the machine takes the appropriate amount for each print. If machine is stopped in the middle of a printing action, take sheet supporting vacuum table and the screen cylinder both return to their original starting position for that particular print. The slack in the web is consumed by the festoon and both the half finished prints back-edge and the screen cylinder are in register. If machine is started again the half-finished print will simply be over-printed, leaving no traces or dirt marks.

Title: Hydro-mechanical power unit - has engine-driven pumps supplying ram driving further pumps by rack and pinion
IPC: F16H43/00
Filed: 1974-12-11
Abstract: An engine (1) drives a pair of pumps (3, 4), which in turn cause a hydraulic ram (5) to operate. This drives by a rack-and-pinion mechanism (6) a further pair of pumps (7, 8) which actuate ram (9) and so on. Hydraulic energy is thus transformed into increased mechanical energy, which is re-transformed into hydraulic energy, the process being repeated as desired, and finally relieving the driving engine of load.

Patent NL-7909062-A (NL)
IPC: F27D25/00
Filed: 1979-12-17
Abstract: Slag deposited on the bottom of a steel making furnace, especially a soaking pit for steel ingots, is difficult to remove. To enable this to be done while the furnace is hot, it is now proposed to supply a substance, e.g. ferro-silicon, which lowers the melting point of the slag, and a substance which reacts exothermically to initiate melting of the slag. When the slag is sufficiently liquefied, it is removed by means of a mechanical grab.

Title: Back-seating system and stop for valve operator - enables use of narrow dia. stem rising only short distance at end of valve travel
IPC: F16K41/14
Filed: 1981-08-11
Abstract: The gate valve has a backseat which is made up only when the normally non-rising operator stem is permitted to rise a short distance. A smaller-dia. stem may be used than one which is of sufficient area where it passes through the stem packing to cause the internal pressure within the valve cavity to generate sufficient force to overcome the frictional forces resisting stem movement developed by the internal pressure between the gate plates and the seats. To make the stem rise when it is supposed to, to make the backseat, a system of clearances is provided between the stem nut and the gate plates. A different stop arrangement is shown for limiting rising of the gate, for defining the fully open position of the gate.
Patent NL-8300098-A (NL)
IPC: C21B5/00
Filed: 1983-01-12
Abstract: Pulverised coal feed tanks 13,14,15 are emptied in sequence via a transport line 25 into the hot blast of a blast furnace. Each tank is carried by three load cells 40 whose outputs are summed and differentiated to obtain the actual feed rate. Gas pressure in the tank is controlled in dependence on the actual feed rate so as to achieve a desired feed rate. To reduce the possibility of inaccurate feeding of coal, the outputs of the respective load cells 40 are compared, and if deviation from a predetermined weight distribution over the load cells is detected, feed from the tank is stopped. The load cells may be duplicated in series, and the summed outputs of the two sets of load cells 40a,40b compared to detect malfunctioning of a load cell, again resulting in cessation of feeding from that tank.

Abstract: Use of finely divided aqueous cationic dispersions of synthetic resins obtainable by emulsion polymerization from suitable monomers and which contain cationic dispersion polymers, as impregnants and primers for consolidating and priming of porous absorbent substrates, preferably inorganic substrates such as, for example, masonry, concrete, plaster surfaces, gypsum surfaces, bricks or wood, by treating these substrates with the aqueous cationic dispersions whose polymer particles have mean particle diameters of 0.02 to 0.2  mu m. Aqueous cationic dispersions of synthetic resins exhibit a superior penetrating and permeating power, in particular on smooth plaster surfaces and smooth gypsum surfaces, compared with aqueous anionic or non-ionic dispersions of synthetic resins. Moreover they have no tendency to foam formation and can, in contrast to aqueous anionic or non-ionic dispersions of synthetic resins, exhibit a sealing action against staining, water-soluble substances, such as tarry products (tobacco smoke), resins, wood constituents (tanning) and dyes, which is of particular advantage for example in the building trade in the renovation of old buildings.
