Title: Mowing tool for hand-controlled rotary mowers
Inventor: VEDOVA ORLANDO
IPC: A01D34/73
Filed: 1981-06-11
Abstract: The mowing tool, which is provided especially for use in lawnmowers, has a cutter bar (1) with cutting edges (3). Attached to each end (1a, 1b) of the cutter bar is a wing (4) which extends rearwards in relation to the direction of rotation (C). Each wing has not only along its outer edge (8) an outer lug (10) bent out of its plane, but also on its inner edge (11) a second lug (12) which can be bent at the same angle as the first lug. The second lug (12) can have a different shape from the first lug (10), and it can also be higher than that in relation to the wing plane. The regions (5, 6, 13), about which both each wing (4) is bent relative to the cutter bar (1) and the lugs (10, 12) are bent relative to the wing (14), are highly rounded. As a result of the arrangement of the second inner lug (12), a powerful, but nevertheless relatively quiet airflow is generated, together with the outer lug (10), by the rotating mowing tool, this airflow guaranteeing a tangential conveyance of the mown grass out of the housing into the grass-collecting device of the lawnmower. <IMAGE>

Patent DE-3150240-A1 (DE)
Title: Arrangement of the oil feed apertures on a screw compressor
Inventor: PIETSCH ALEXANDER DIPL ING DR
IPC: F04C29/00
Filed: 1981-12-18
Abstract: The invention relates to a screw compressor with two rotors. Oil is injected for the cooling, lubrication and sealing of the internal gap. The rotary movement of the rotors opens and closes the oil feed apertures by covering and freeing these. In the open position the inlet and outlet of the gap pair are closed and the pressure therein lower than the compression outlet pressure. The object of the invention is to improve the efficiency by arranging the oil feed apertures so that the drive losses due to friction and delivery of the oil are minimised and the cooling action maximised without adversely affecting the lubricant and sealing effect. According to the invention the oil feed apertures are always connected to the gap pair, which runs behind the expelling gap pair. The open position begins when the expelling gap pair has reached the outlet aperture. The oil feed aperture is closed by the respective following tooth once the expelling process is completed. The invention is particularly suited to the compression of oil-soluble gases.

Patent DE-3202077-A1 (DE)
Title: Bookmark for any type of book
Inventor: BALDUS FRANZ DIETHER
IPC: B42D3/14
Filed: 1982-01-23
Abstract: Conventional, loosely insertable bookmarks are easily lost. In the event of carelessness, they slip out between the pages of the book and the reader has difficulty in finding the marked page of the book again. The bookmark according to the invention avoids these disadvantages. It consists of a folded-over piece of paper, between the two parts of which a coloured ribbon is fixed. One side of the paper remains self-adhesive on the outside, as a result of which it can be caused to adhere to the back cover of the book. Thus, the bookmark can never inadvertently slip out of the book. It can also be inserted more easily between the pages of the book, since one of its ends is fixed internally to the back cover of the book.
Patent DE-3203842-A1 (DE)

The gas is subject to the action of a high centrifugal acceleration in the slot, which has a radius of curvature of approximately 1 to 100 mm.
Patent DE-3205802-A1 (DE)
Title: Process for atmospheric fractional distillation of crude oils
Inventor: WIRTZ GERHARD
IPC: B01D3/14
Filed: 1982-02-18
Abstract: In the atmospheric distillation of crude oils, only such a quantity of heat is initially supplied to the crude oil in a preliminary stage before the main stage, utilising the heat released in the condensation of the distillate vapours, that only the light hydrocarbons and gasoline fractions vaporise, and in particular the vaporisation of the light hydrocarbons and gasoline fractions is carried out in two series-arranged fractionation columns or in a single fractionation column without using extraneous heat. In the case of the prevaporisation in two series-arranged fractionation columns, the downstream second column runs at a pressure which is 1 to 5 bar higher than the pressure in the first column of the preliminary stage and in the column of the main stage, the heat of condensation of the vapours from the second column being utilised in a heat exchanger upstream of the first column for heating and partially vaporising the crude oil in the first column. If only one fractionation column is used in the preliminary stage, this runs at a pressure which is 1 to 5 bar higher than the pressure in the column of the main stage, and the heat exchanger upstream of the fractionation column of the preliminary stage preheats the crude oil by the heat of condensation of the vapours from the fractionation column for further heating, before the crude oil is brought to the vaporisation temperature of the preliminary stage by the heat of condensation of the vapours and/or hot product streams from the main column.

Patent DE-3225663-A1 (DE)
Title: Drainage element and method of producing the same
Inventor: DREFAHL JENS ING GRAD
IPC: E04D11/00
Filed: 1982-07-09
Abstract: A drainage element, in particular for the cultivation of plants on flat or sloping roofs, and a method of producing the same are described. The drainage element has a water-permeable filter mat which serves to accommodate a plant soil and is supported by finely distributed, thin spacers fastened to it over any base, such as a natural soil or a base mat connected on the foot side to the spacers. A drainage system with ample hollow spaces is defined below the filter mat by the spacers. The drainage system enables excess water to flow off virtually unimpeded. The supporting spacers are designed so as to draw and conduct water, so that even the smallest quantities of water can pass from the base to the filter mat and the plant soil located above it. The filter mat can be provided at the top with projections similar to or different from the spacers. The projections accommodate the plant soil in such a way as to inhibit slipping and if need be enable the roots to be anchored. The projections can also be designed to draw and conduct water like the spacers in order to ensure quick, uniform and intensive wetting of the soil. The water-conducting parts of the drainage element can be made of an absorbent material or can also have capillaries or absorbent coverings. The latter can be produced by electrostatic flocking, spraying or immersion; cellulose ether is especially suitable as covering material.

Patent DE-3240594-A1 (DE)
Title: Method and device for stabilising a soft subsoil
Inventor: SCHWEIKERT OTFRIED
IPC: E02B3/12
Filed: 1982-11-03
Abstract: The invention relates to a method of stabilising a soft subsoil, e.g. the bottom of a drainage channel, by means of unhewn stones of irregular size. In order to avoid laborious insertion of the individual stones into the subsoil to be stabilised, it is proposed to first of all insert the stones into a mould box with the side intended as top side facing downwards and to then accordingly fill the mould box with a filling material, e.g. of stone chips, etc. The mould box is then covered and tipped over at the location to be stabilised, as a result of which stabilisation with a plane top side is guaranteed in a single operation. In order to guarantee a uniform pressure distribution between the stones and the subsoil to be stabilised and at the same time permit better banking against the stabilised subsoil, it is proposed first to lay a grid or tile in the box, which grid or tile is ripped up after the contents of the mould box are tipped out onto the location to be stabilised and is placed with the lobes resulting from this against the slope. <IMAGE>

Title: Hydraulic drive on displacing and centring devices
Inventor: WETTER JACOB
IPC: B21B39/14
Filed: 1982-11-04
Abstract: Arranged in front of and/or behind a forming machine, on both sides of the roller table, are cylinders which are arranged opposite one another and, for handling rolling stock, carry slide bars or contact-pressure devices with their piston rods. To achieve synchronism, the cylinders are connected together in accordance with the positive displacement principle. In order to be able to perform centring and displacement of the rolling stock in the clamped condition, an additional control valve is connected to each pipe connecting the annular space to the piston space of cylinders lying opposite one another. Volume compensation of the differing volume between the two cylinders of a cylinder pair in the displacement space, which may have changed, is achieved by means of an additional inlet valve and an outlet valve arrangement in the connecting line between the two cylinders.
