Title: Correction device for supercharged fuel-injected internal combustion engines
Inventor: LAHL FRITZ
IPC: F02D23/00
Filed: 1982-04-16
Abstract: The invention relates to a correction device for supercharged fuel-injected internal combustion engines, especially diesel engines with exhaust gas turbocharger, the correction device having a diaphragm control known in the art, which is acted upon by the charging air pressure and acts in concert with a lever mechanism located in a housing, which mechanism varies the position of a delivery quantity adjusting element. All adjustment points on the lever itself and in its immediate vicinity are accessible by means of a central opening on the housing. The correction transmission distance is free from play due to a suitably arranged spring. The invention is intended to facilitate centrally accessible and sensitive adjustment without special tools, to reduce wear and thereby extend the interval between adjustments.
Patent DE-3221357-A1 (DE)
Title: Process for the production of moulds and cores for casting purposes
Inventor: KAHN FRIEDHELM PROF DR
IPC: B22C9/12
Filed: 1982-06-05
Abstract: A layer of binder is applied to the surfaces of a pattern or core box, mould material is introduced and compressed, and the layer of binder is hardened to a shell, while the mould material enclosed by, and supporting, the shell remains free of binder. The process is distinguished by being versatile and adaptable to different binder systems and mould material systems, and leads to a reduced quantity of binder, better disintegration or easier release of the mould part after casting, to better surface properties of the castings, and better gas permeability in spite of compression being more easily performed. The process is particularly suited to the production of cores for light metal castings.
Patent DE-3225524-A1 (DE)
Title: Method and apparatus for drying vehicles
Inventor: BURGER HORST
IPC: B60S3/00
Filed: 1982-07-08
Abstract: In vehicle washes, the vehicles are washed with a detergent, rinsed and then sprayed with a medium which increases the surface tension of the finish of the vehicle, before the water is blown away with air. In order to achieve rapid drying, after the vehicle has been sprayed with the medium increasing the surface tension, the vehicle is subjected to another pressurised rinse with water and the water droplets then formed are mechanically brushed away from the surface of the vehicle by filaments arranged in the manner of a curtain, before the subsequent air drying.
Patent DE-3231000-A1 (DE)
Title: Concrete ring for forming terraces and walls
Inventor: EHL BERNHARD
IPC: E02D29/02
Filed: 1982-08-20
Abstract: The object is to develop further a concrete ring for forming terraces and walls. The walling (1) of the said concrete ring is on the one hand curved outwards and on the other hand, to achieve a form-fitting connection to the next-following concrete ring, is curved inwards. If such concrete rings are arranged in the form of steps and are filled with earth, plant and water-retaining areas are formed and consequently allow grassing over or planting with shrubs; if, on the other hand, such concrete rings are set vertically one on top of the other to erect a wall, the plant areas are lost. The further development provides a novel concrete ring by which even vertical walls can be formed with the provision of plant and water-retaining areas. The special feature of the novel concrete ring is that the walling (1), seen over the circumference, comprises four sections (1a, 1b) of equal length which are alternately curved, preferably circularly, outwards and inwards. The concrete ring may, moreover, also be provided with bottom terminations and have reinforcing ribs, in particular a central web. <IMAGE>

Patent DE-3302480-A1 (DE)
Title: Safety anchor for shelter closures
Inventor: RIEGER BERNHARD
IPC: E06B5/12
Filed: 1983-01-26
Abstract: A neat introduction, alignment and casting of gastight and compression-proof shelter closures is exceptionally difficult according to existing methods because elements often have a great weight and the casting of the frames cannot in most cases take place immediately after mixing. With a safety anchor, the main features of which have in each case a right-hand thread and a left-hand thread on the anchor screws, a fixed point can be produced without drilling, firing and the like, on which elements of any kind can be mounted.

Filed: 1983-02-01
Abstract: A tyre (8) for a motorbike has a tread (10) with two rows of channels (12 and 14) which extend around the tyre (8). The channels (12, 14) of each row are inclined at equal and opposing angles with respect to a circumferential line of the tyre (8) and the channels (12) of one row are arranged offset along the circumference with respect to the channels of the other row. The channels (12, 14) are sufficiently long to draw water off out of the contact ellipse of the tyre (8). Two additional rows of channels (22, 24) which extend at an angle of approximately 90 DEG  with respect to the channels 12 to 14 are also provided in the tread (10). The channels (12, 14, 22, 24) are completely bounded by the tread (10) and, as a result, movement of tread blocks, which would bring about uneven wear of the tyre, is reduced. <IMAGE>

In a further special design, instead of the block bearing the drive motor is arranged in the support frame and the fan impeller directly connected to its output shaft.
Patent DE-3316040-A1 (DE)
Title: Building element for producing walls capable of receiving a vegetative cover
Inventor: KRUEGER JOACHIM
IPC: E04C1/39
Filed: 1983-05-03
Abstract: The building element (10) is funnel-shaped and has loadbearing side walls and visible walls (24, 25). The building element (10) is open at the top and at the bottom. The bottom opening (35) is large enough for filling material (46) poured into the building element (10) from the top to be able to run out without getting stuck. To produce a wall (40), the building elements (10) are stacked, in a first step, offset one above the other on a foundation strip (41). This produces vertical continuous funnel channels (45) arranged next to one another. These channels are filled from the top with filling material (46) in a second, independent, step. As soon as the building elements (10) of a funnel channel (45) have thereby successively filled up, starting from the bottom, a cone (47) forms above each building element (10), which cone blocks the outlet opening (35) of the next building element (10) up. The exposed cones (47) are capable of receiving a vegetative cover. <IMAGE>

In order for the training bench to be able to be stored in a space-saving manner when not in use, the feet of at least one end are to be designed as an independently self-supporting chassis which possesses at least one vertical socket for the end of the support and for a pin projecting at an angle therefrom.
Patent DE-3328101-A1 (DE)
Title: Ball-head pin, prepared for the measurement of force, for measuring force components acting on the ball head
Inventor: WEIGER GUENTER
IPC: G01L5/16
Filed: 1983-08-04
Abstract: The invention relates to a ball-head pin which is appropriately designed for measuring forces transmitted in a ball-and-socket joint. Integrated in the ball head for this purpose is a measuring disc which merges in one piece into an equatorial strip of the ball socket and into the pin. The only connecting members in between are measuring webs which are provided with wire strain gauges. Shell-shaped sections, which are connected only to the outer periphery of the measuring disc, complete the measuring disc to form the ball head. Since the entire force flow from the ball surface to the pin is transmitted solely by the measuring webs, their deformations can be used to determine the size and direction of the joint forces. On account of the design without bridges affected by hysteresis between ball head and pin and through direct measurement of deformations due solely to material elasticity, measuring errors can be avoided and the measuring accuracy is thereby increased compared with known devices.
Patent DE-3329458-A1 (DE)
Title: Wrapper made from deep-drawn plastic
Inventor: MICHEL WOLFGANG
IPC: B42F13/14
Filed: 1983-08-16
Abstract: A wrapper made from deep-drawn plastic consists of an integral rectangular blank which has a flexible folding strip of 5 to 15 mm width arranged centrally and parallel to the two narrow sides. Raised portions and associated cut-outs or recesses are integrated with the blank in mirror-image form and parallel to the centre line of the flexible folding strip, at a distance of 12 to 18 mm apart. If the wrapper is used as a rapid binder, it is folded along the flexible folding strip, the raised portions engaging into the cut-outs or recesses. In this arrangement, the raised portions serve as receiving lugs for perforated sheets, leaflets, documents and other material. The wrapper can also be designed as a transparent wrapper with a closure system. In this case, the raised portions and cut-outs or recesses are arranged close to the edges of the narrow sides and also, as required, along the broad sides of the blank. <IMAGE>
Patent DE-3332028-A1 (DE)
Title: Arrangement for generating an FSK-modulated signal
Inventor: BOSCHKA WILFRIED ING GRAD
IPC: H04L27/12
Filed: 1983-09-06
Abstract: For generating an FSK-modulated signal of a certain mid-frequency and a certain line spacing from a normal frequency, there are provided devices for frequency division, which set the mid-frequency by adjustable divider factors, and a phase shifter network having a plurality of outputs with equidistant phase-influencing steps. The side lines are generated by connecting one of the outputs of the phase shifter network in each case cyclically in succession to the output of the arrangement, by using switching means which are operated in time with an adjustable switching frequency. The rotational direction of the switching means is fixed according to the binary data signal and determines the direction of the frequency shift, while the adjustable switching frequency determines its amount. The switching frequency is advantageously derived from the normal frequency by frequency division.
