Patent NL-7905697-A (NL)
Title: Heat economiser for a water heater - has ball valves closing inlet and outlet in absence of flow
IPC: F24H9/12
Filed: 1979-07-24
Abstract: Seats for valves are provided at the inlet and outlet of a heat economising system which prevents the loss of heat through pine fittings on a storage vessel for warm water. One valve seat is arranged in the nipple assembly on the outside of the vessel for the cold water inlet, whilst a second valve seat is positioned in the nipple assembly outside the vessel for the hot water outlet. In the nipple assembly at the cold water inlet there is a stop which allows the passage of water through the cold water inlet. In the nipple assembly at the hot water outlet there is a stop which allows the passage of hot water through the hot water outlet. Each stop is positioned lengthways in the nipple assembly away from the valve seat. A first seal placed in the cold water inlet, has a density =0.95, and is intended to float upwards in the water into contact with the valve seat when no water flows inwards, so that there is no heat loss from the stored water through the cold water inlet. A second seal placed in the warm water outlet has a density >=1.10 and is intended to sink in the water into contact with the valve seat when no hot water is leaving the vessel. Heat losses from the hot water in the outwards direction through the hot water outlet are thus also prevented. The stops prevent the carrying away of the seals through the inlet and outlet when water is flowing. Effectively prevents heat losses through the connecting fittings of the storage tank.
Patent NL-8003332-A (NL)
Title: Wear-resistant lining of bore for extrusion press worm - first applied on mandrel which is then inserted in bore and mandrel machined out
IPC: B29C48/03
Filed: 1980-06-06
Abstract: The arrangement is intended for applying a wear-resistant tubular lining to the inner surface of the housing bore containing the transport worm of an extrusion press. A cylindrical mandrel is first provided with an external wear- resistant deposit and machined so that it fits accurately in this bore. After insertion in the bore, the material of the mandrel is removed by a machining operation leaving the deposit in position. The final machining operation may remove a surface layer of the wear-resistant material. For a twin-screw extrusion press, two such mandrels may be coated and provided with flats so that they can together be inserted in the twin bores, after which the deposits are joined together and to the housing by soldering, preferably vacuum-soldering (at 11). Used for plastic extrusion press. This method overcomes the inadequacy of wear resistance produced by surface-hardening of the housing material of the bore wall. It also avoids stresses and deformation due to differential elasticity and differential expansion occurring when a wear-resistance insert bush is fitted by a material cast into the annular space between bush and bore wall. Such stresses and deformation lead to increased wear.

Title: Coke oven battery regenerator out of action during repair - is connected to other hot run regenerators to prevent excessive cooling
IPC: C10B29/06
Filed: 1981-08-03
Abstract: The arrangement is for preventing excessive cooling of a regenerator (719; compartments 19, partition 18) in a coke oven battery when that regenerator is out of action during a repair e.g. to a combustion chamber wall (718/719,719/720) adjoining a coke chamber (not shown) above that regenerator. Hot combustion gas from other regenerators (715,723), which are operating, is passed (via 20) through the regenerator (719). The hot gas may be transferred via at least one duct (20) arranged in the passage at the rear and/or front of the battery and preferably enters (22) the regenerator (719) at the rear and/or front face at a level above the refractory heat storage material contained therein. The arrangement prevents the formation of cracks through shrinkage in the refractory walls separating adjoining regenerators.

Title: Insulated section of oil well steam injection string - has thermally expanded inner tube welded to outer tube, coupling by screw sleeve
IPC: E21B36/00
Filed: 1981-08-17
Abstract: The insulated tube sections are intended for coupling to form a tube string for placing into a (cased) bore hole to inject steam into an oil-bearing formation. It comprises a thermally expanded inner tube (21) inside an outer tube (25) with insulating material (28) and spacer rings (not shown) in the annular space (27) between them. End rings (22) first secured (23,24) around the tube (21) near its ends (35) are internally secured (26) to the ends of the tube (25) whilst the tube (21) is in its expanded condition, after which male (taper pipe) thread (32) is cut on the tube (25) ends for intercoupling double-walled insulated tube sections so produced by means of coupling sleeves (31) having corresp. female screw thread (33) at their ends. Insulated double-walled tube sections for steam injection (or hot product extn.) tube string in bore hole of oil well. Pre-insulated tube sections, which are preferable because in-situ insulation precludes inspection after installation, suffer from heat loss via the couplings, which is prevented by the design of this disclosure. Pre-expansion of the inner tubes avoids excessive stresses in operation, thus reducing risk of fatigue failure.

Patent NL-8702786-A (NL)
IPC: B65H29/46
Filed: 1987-11-20
Abstract: The invention relates to a device for stacking flat articles, such as postal items. First guide means (9), which form part of a stacker head (7) and which bound a stack of articles (2) already stacked in a stacker bed (1) in a plane of stacking (D), carry out an imposed to-and-fro pulse movement between a rest position (A) and an outermost position (C) transversely to a supply line (3) and in line and level with the stack to make stack space for a short time for an article 2.2 to be stacked, which article is entering at that moment via the supply line (3). The pulse movement can be realized by hanging the first guide means (9) on the one hand by means of a first set of parallel leaf springs (17, 18) to a frame part (19, 20, 31, 32) in such a way that they can swing, and on the other hand by coupling them to the driving end (28) of drive means (25, 26) carried on bearings in the frame part. In the rest position (A) the stack pressure exerted in the plane of stacking (D) on the first guide means (9) of the stacker head (7) will (practically) completely be exerted as a sideways pushing force on the frame part. This fact can be utilized with advantage for a very accurate stack-force measurement. For that purpose the frame part is connected, on the one hand, via a second set of parallel leaf springs (33, 34) to the fixed world (35, 36, 4) and, on the other hand, via a coupling bar (37) to a force transducer (38, 39). A very small sideways displacement of the frame part under the sideways pushing force caused by the stack pressure is registered by the force transducer (39) and converted into a signal which can be used for a change of position, if any, of a stack support (8) for regulating the stack pressure.

Abstract: The chair has a seat or seat portion equipped with a balance and its linkage structure has links fixed in articulated manner to a support arm and to which there is articulated a balance device in parallelogram-like manner. A slide is slidingly guided on the balance device and is connected by means of a thrust rod to an extension arm of the backrest-side link. The slide is also connected to one end of a spring element, the other end of which is supported on the balance device. The linkage structure is supported on the backrest by means of a backrest strut articulated to the slide. The seat and backrest portions of the chair frame can be constructed as a plastic shell with a knee-side bending joint and a further bending joint between the seat portion and the backrest portion. Due to the construction of the chair frame to incorporate a balance device, as least part of the forces exerted by the occupant or user of the chair can be absorbed by the balance device, so that the spring element can be made smaller and therefore less expensively, and there is also no need to adjust or adapt the spring element to different body weights of the users of the chair.
