IPC: B23K35/38
Filed: 1968-02-23
Abstract: 1,225,361. Soldering. ROBERT BOSCH G.m.b.H. 23 Feb., 1968 [24 Feb., 1967; 2 Sept., 1967], No. 8788/68. Heading B3R. [Also in Divisions C7 and F2] In soldering a metal terminal to a semiconductor molten solder is applied in a reducing protective atmosphere to at least one of the bodies and the bodies are subsequently soldered together. The molten solder may be applied to a terminal in the form of a headed copper wire coated with nickel or to a metallized semiconductor body and the parts are subsequently heated together in a reducing atmosphere without the use of flux to effect their soldering. The metallizing on the semi-conductor body may be produced by applying a masking lacquer (picene or bituminous varnish) which divides the body into separate areas and electroless nickel is coated on the unmasked areas. The mask is removed and the body is coated with molten solder which adheres only to the metallized areas. In making a transistor a terminal provided with applied solder is soldered to the collector surface on one side of the semi-conductor body whilst the other side of the body having emitter and base structures is provided with applied molten solder. An apparatus for applying molten solder to headed terminal wires II comprises a vessel 14 containing 92% lead, 8% tin alloy kept molten by heating coils 15 and a centrifugal pump 18 which draws solder through a bore 19 and pumps it through a tube 20 to emerge from a nozzle 21 as a jet 10 which falls back to the solder in the vessel. A guide passage 22 through which terminal wires are fed at right-angles to the direction of the jet is mounted above the vessel 14 to extend across the vessel and is adjustable for height above the vessel by a screw-threaded ring 25. Hydrogen or hydrogen and nitrogen is fed through heating passages and then fed into the passage 22 above the vessel to flow in both directions along the passage. The terminal wires are arranged in magazines and these are fed through the passage across the jet of solder by an intermittently driven feed pawl, the wires being heated to 560‹ C. before reaching the jet to remove oxide and being cooled after leaving the jet. A liquid solder seal 33 is provided between the passage 22 and lid 24 of vessel 14, an overflow channel 35 and pipe 36 for protective gas being included and means for topping up the seal by deflecting solder from the jet.

Title: Incinerator for waste products from processing hard vegetable matter - has material and generated gas burnt in two stages to limit pollution
IPC: F23G5/027
Filed: 1987-03-03
Abstract: The incinerator has a first chamber (1) with fireproof walls (2, 3) and an inlet chute (4) with a hinged cover (5). The base of the first chamber is pierced by holes (8) allowing oxygenated gas, e.g. air or enriched air, to flow upwards through the material during combustion. The gasses produced by the partial combustion pass through an aperture (12) into the second combustion chamber (13) where more oxygenated gas is added (15), and gaseous combustion products are extracted (16). The hot gasses are then passed through a heat exchanger (18) to extract the useful energy. The cooled gasses gather in a chamber (19) at the end of the exchanger and are discharged to the atmosphere via a chimney (20). A sufficient flow of oxygen through the system may be provided by an electric extractor fan in the chimney.

Title: Delimited space, the size and shape of which are reversibly variable
IPC: E04H15/34
Filed: 1994-03-09
Abstract: The invention relates to a delimited space, having at least one closure which runs in a horizontal, diagonal or vertical plane with respect to the space and by means of which the size and shape of the space can be varied. Consequently, it is no longer necessary to stick to one format. The invention provides a frame structure which is simple yet universally applicable, and any desired number of frame parts can be added to the corners; these frame parts can be fitted at a variable angle with respect to one another. Some aspects of the invention are produced in the preferred embodiment of a conical teepee, in which the larger formats are suitable for relatively large groups, while the smaller model in this way becomes suitable for use as a lightweight hiking tent. A lightweight inner skeleton in the smoke flaps limits the number of poles. A horizontal storm ring provides additional strength and the possibility of attaching the inner guide, and also allows the number of poles to be limited further. A rubber lug or projection is used to hold the poles together at the top and to facilitate erection of the tent. The round groundsheet can be used as at least one rain cape and is also of adjustable dimensions in order to be adapted to the various formats, by being equipped with features making it removable.
