Patent DE-3605070-A1 (DE)
Title: Cyclone precipitator
Inventor: SCHMIDT PAUL DR ING
IPC: B04C5/103
Filed: 1986-02-18
Abstract: In order to increase the separation selectivity, to strongly reduce the pressure loss and, to a lesser degree, the separation granule size of a cyclone precipitator, a guiding device with two or more guiding shovels which are wound in a helical shape is constructed in such a way that they have a gradient of 45 DEG  +/- 15 DEG . For the sake of simple manufacture, they consist of fibre-reinforced material. On the inside of the cover of the cyclone housing, there is a guide spiral which conveys outwards and at the bottom one which conveys inwards; as a result, the guidance of the separated material is promoted. A core which is arranged in the guide device avoids dead water flow and accumulation of dust. The fields of application are dedusting hot gases, recovering powdery products and cleaning the intake air in internal combustion engines.
Patent DE-3606830-A1 (DE)
Title: Electric plane
Inventor: BACHMANN RAINER
IPC: B27G13/04
Filed: 1986-03-03
Abstract: To reduce the weight and the manufacturing costs of electric planes, the invention describes a lightweight, very handy and inexpensive electric plane which has a sectional-steel cutter block base body preferably mounted on one side and with factory pre-assembled sectional-steel cutter block covers for accommodating the reversible cutters. The mounting of the cutter block on one side makes possible a large rabbet (rebate) planing depth. The casing is designed to ensure easy and safe handling.
Patent DE-3607311-A1 (DE)
Title: Cigarette pack with integrated box of matches
Inventor: DAUBEN JOACHIM THEODOR
IPC: B65D85/10
Filed: 1986-03-06
Abstract: The intention of the invention is to provide in a single package both cigarettes and an appropriate supply of matches. The user will thus be independent of other external sources of fire and is protected from their possible malfunction, in particular from the loss thereof. The restriction to the external dimensions of the so-called "100 mm packs" which are already on the market afford the manufacturer considerable rationalisation advantages and the user the familiar pack size.

Patent DE-3632076-A1 (DE)
Inventor: SCHMITZ FRIEDRICH
IPC: H03F1/30
Filed: 1986-09-20
Abstract: In each branch of the transistorised push-pull output stage (1, 2), a sensing element (4, 5) is arranged across which in each case a voltage measured with respect to reference potential can be picked up. These voltages are connected to one input each of a differential amplifier (10). The output voltage is connected to a comparator (13) which compares it with a reference voltage (Uref). The output of the comparator circuit (13) controls an electronic switch (16), in such a manner that it charges an electric store (18) the charging voltage of which controls the quiescent current of the push-pull output stage (1, 2). <IMAGE>
Patent DE-3635261-A1 (DE)
Inventor: HERRMANN ALFONS
IPC: F16C33/50
Filed: 1986-10-16
Abstract: An endless loop (1) for cages of all kinds of roller bearings is injection-moulded, cut in the longitudinal direction and directly used as a linear bearing or, after folding together, as a ring bearing.

Title: Device for retaining tubular tyres
Inventor: GROSS REINER
IPC: B60B21/12
Filed: 1987-02-10
Abstract: A device for retaining tubed tyres (1) on rims (4), especially of bicycles, is described, using at least one elastically resilient layer of coupling agent in the form of a tape, with one tape being fastened firmly and permanently to the inner circumferential surface of the rim where the latter engages with the tubed tyre, as rim tape (3), and another tube tape (2) being permanently attached to the tubed tyre in the area that engages with the rim. An essential feature is that the two areas of the tube tape and the rim tape brought into contact when the tubed tyre is mounted on the rim have surface structures that ensure a positive connection between the tube of the bicycle or the like and the corresponding rim, as well as the usual non-positive connection. <IMAGE>

Patent DE-3716344-A1 (DE)
Title: Granite concrete stone
Inventor: KUHLMANN JUERGEN
IPC: E01C5/06
Filed: 1987-05-15
Abstract: This novel granite concrete stone shows the character of a natural granite stone and, when roughened, has a silky sheen which in some cases exceeds even the gloss of a natural granite stone. After the success of the basalt concrete stone (DE-OS-3,531,772) of related type, it was obvious to attempt the preparation of a granite concrete stone having corresponding properties. After many unsuccessful attempts, this was unexpectedly achieved by the addition of fractions of diabase grains, and in particular with a relatively very high proportion of diabase powder. The granite concrete stone, obtained in this way and consisting exclusively of granite grain fractions, diabase grain fractions, cement and water, has, in addition to the visual character of a natural granite stone, a high static strength and a likewise high resistance to the effects of temperature and weathering. The illustration, an enlarged section of a granite concrete stone, diagrammatically shows the distribution of the larger and medium-size granite and diabase grain fractions (1, 2, 4, 5) and of the small particles (3, 6) of granite powder and diabase powder on the surface of a granite concrete stone. <IMAGE>

Patent DE-3721008-A1 (DE)
Title: Sandwich material or sandwich material element, and process for manufacturing it by vacuum-plasma spraying
Inventor: HODES ERICH DR
IPC: C23C4/137
Filed: 1987-06-25
Abstract: A sandwich material or sandwich material element having a functional layer of metallic dispersion alloy, applied directly or via an interlayer to a base layer, is considerably improved by the alloy components of the dispersion alloy being united in the functional layer as fine particles in a fixed mixing ratio with respect to one another and in random distribution in lamella-free and virtually pore-free association held together by mutual adhesion. This can be achieved by applying the functional layer by vacuum-plasma spraying (VPS). At the same time, dispersion hardening can be achieved by incorporating hard particles in the form of very fine particles, possibly by generating said hard very fine particles by reactive vacuum-plasma spraying and incorporating them in the rescent state into the functional layer, for example Al2O3 particles by adding oxygen to the plasma in the case of vacuum-plasma spraying of dispersion alloy containing aluminium. An additional treatment (after-treatment, secondary treatment, finishing treatment) of the functional layer generated by vacuum-plasma spraying is generally unnecessary, except for optional smoothing of the surface in a dressing-rolling (skin pass rolling) pass. There are advantages in the prior preparation of an alloy powder to be fed to the vacuum-plasma spraying process, by mixing and agglomerating the comminuted alloy components, optionally with admixture of the very fine hard-material particles.

Title: Method for producing brown-coal dust
Inventor: KLUTZ HANS-JOACHIM DIPL ING
IPC: B02C15/00
Filed: 1987-10-10
Abstract: The invention relates to a method for producing brown-coal dust in a mill. Due to the great reactivity of the brown coal, the grinding of brown-coal dust can take place only in an inert atmosphere. Vibration grinding mills are known for this purpose. The object of the invention is to improve the quality and fineness of the brown-coal dust and at the same time reduce the complexity of the equipment while maintaining a high operational safety. This object is achieved in that pre-dried and pre-crushed brown coal (1) is ground to dust fineness in a bowl mill crusher (2) at low temperatures and approximately under atmospheric pressure with continuous feeding of inert gas (5). Dry flue gas (11) is used as the inert gas (5). The brown coal (1) is ground to dust at temperatures around 60@C in the bowl mill crusher (2). A partial quantity (10) of the inert gas (5) is continuously discharged and renewed by an equally large partial quantity (11). <IMAGE>
