Patent DE-3523559-A1 (DE)
Inventor: KOKHOLM JENS PEDER
IPC: A01F29/00
Filed: 1985-07-02
Abstract: By a method for cutting up for example straw bales (1) a number of knives or spears (2, 3) are driven through the bale (1) by means of hydraulic cylinders (15). The cylinder (15) is pivotally secured to a post (8) in such a manner that additional hydraulic cylinders (6) may swing the upper knives or spears (2) upwards, whereas the remaining knives or spears (3) act as holding knives holding the bale (1) while the cut off part (10) of the bale is thrown into the opening (13) of a lock (9) which for instance may lead to a straw furnace, whereupon a lifting means (5) carry forward the bale for a new cutting operation. To ensure that the cords surrounding the bale (1) are cut, there is moreover provided a cutting knife (20) which by means of hydraulic cylinders (21) is pressed into one side of the bale. This method ensures that the cords are cut and that the bale of straw is cut up effectively and with no substantial energy consumption just as the shown apparatus is very simple and reliable.

Title: Apparatus for generating biogas
Inventor: HEINRICH MANFRED
IPC: C02F3/28
Filed: 1985-07-26
Abstract: To improve the degradation conditions of the anaerobic degradation of organic wastes, a fermentation duct for biogas generation is operated in such a way that the symbiotic processes of the participating microorganisms are promoted and that a certain proportion of active biomass is retained in the fermenter. These results are achieved by a special configuration of the substrate inlet pipe, an appropriate arrangement of the internal heating surfaces of the fermenter and by apparatuses in the bottom region of the septic chamber. In addition, inert solids can be added to the substrate. These measures lead to an increase of the degree of degradation and of gas production and to a stabilization of the microbial degradation process.

Title: Apparatus for transporting structural parts in underground operations
Inventor: RAUSCH REINHOLD
IPC: B60P1/54
Filed: 1985-07-30
Abstract: In reconstruction and support work in underground operations, in particular in roadways, roadway transitions and the like, it is often necessary to transport comparatively heavy structural parts from one place to another. This is normally done by hand, since the use of conventional transport equipment is not possible on account of the restricted space conditions. The object of the invention is to create an apparatus for transporting structural parts in underground operations which enables this to be carried out in a simple, quick and safe manner. According to the invention, this is achieved in that this apparatus has a crawler-type vehicle (2), between the travelling chains (3, 4) of which a roughly trough-like loading space (5) is located which extends from one open end (6) of the crawler-type vehicle (2) up to roughly its centre area, and that in the area of the other end (7) of the crawler-type vehicle (2) a telescopic boom (8) is pivotably mounted in a bearing yoke (9), which telescopic boom (8) can be lifted and lowered by means of cylinder/piston units or the like which are linked to the telescopic boom (8) and to the bearing yoke (9) and can be acted upon by pressure medium, and the bearing yoke (9) can be rotated on the crawler-type vehicle (2) by means of cylinder/piston units which can be acted upon by pressure medium. <IMAGE>

Title: Monitoring of the spring damping device of an impact forming machine
Inventor: RUEGER HERBERT DIPL ING
IPC: B21J13/00
Filed: 1985-08-03
Abstract: There is a monitoring device in which a displacement sensor 9, 10, 11; 14 emitting a displacement-proportional output voltage 15 is provided in the spring damping device and connected to the output of which is an evaluation device. It is desirable here to enable continuous monitoring of the reduction in the spring damping travel, the declining damping effect and wobbling movements by simple means. This is achieved by the permanent installation, on both sides of the two horizontal centre lines of the spring damping device, of in each case one displacement sensor 9, 10, 11. The desired versatile monitoring facility can be achieved using three displacement sensors and a relatively simple electric circuit. <IMAGE>

Title: Hinge for the cover plate of a cooker, cooking plate or the like
Inventor: SCHROEDER HENRY
IPC: F24C15/12
Filed: 1985-10-15
Abstract: By means of the hinge, the cover plate of a cooker, a worktop-mounted hotplate or the like can be tilted up from a horizontal position into a vertical position, the cover plate being held there. Through the hinge, a brake friction force is opposed to the tilting-up movement. According to the invention, a U-shaped bearing element made of spring material is used as the pivot bearing in this case, in which bearing element a pivot element firmly connected to the cover plate is pivotably mounted and guided. The bearing element has catch springs which, in the tilted-up position, engage with a bow, concentric with the pivot axis, of the pivot element and hold the cover plate in this position. <IMAGE>
Patent DE-3540109-A1 (DE)
Title: Screw connection on a boring tool and its adaptor
Inventor: BERNER WILLY
IPC: B23B31/11
Filed: 1985-11-12
Abstract: The screw connection between a boring tool and its adaptor, the tool and adaptor each having a thread, is distinguished by the fact that the two threads (3A, 3B) of adaptor (1) and tool (2) are connected by a threaded stem (3) with two different threads (G1, G2) offset from one another and each corresponding to adaptor and tool, and that the adaptor and tool each have a recess (N1, N2) for accommodating a common driver piece and have a driver piece (5) allocated to the recess (N1, N2). On the one hand, the cutting forces consequently no longer act on the screw fitting when working with the boring bar and, on the other hand, the necessary applied pressure between adaptor and tool can be produced. The connection can be easily released after engagement in practical work. <IMAGE>

Title: Operating element having an operating plunger for explosion-protected electrical switching apparatus
Inventor: GOERNER WILMUT
IPC: H01H3/02
Filed: 1986-03-14
Abstract: In order to operate an explosion-protected electrical switching apparatus, an operating element (110) is used which has an operating plunger (136, 131) which can be coupled to the switching apparatus. In order to improve the assembly (installation) convenience, the operating plunger (131, 136) is constructed in two pieces with a plunger pot, which is constructed as a compression part (131), and with an operating spindle (136), which is constructed as a handle part. The plunger pot is coupled to the operating spindle via latching balls (141, 142) which are controlled by a link (130), two circumferential grooves (138, 137) being provided on the operating spindle, of which that groove (137) which faces the switching apparatus has a shallower depth than the other groove (138). The design according to the invention creates an operating element by means of which an explosion-protected electrical switching apparatus can reliably be latched both in the switched-on position and in the switched-off position. <IMAGE>

Patent DE-3627069-A1 (DE)
Title: Monostable flip flop
Inventor: GRAF NORBERT DIPL ING
IPC: H03K3/284
Filed: 1986-08-09
Abstract: A monostable flip flop is specified which, compared with known monostable flip flops, is improved in such a manner that, after its turn-on time has elapsed, after the time at which its output signal resumes its rest state, it is no longer triggerable by further trigger pulses having a predetermined pulse amplitude for a predetermined minimum pause time and can only be triggered again by such pulses after this minimum pause time has elapsed. The circuit is preferably suitable for reducing the pulse repetition rate of pulse sequences to an upper limit frequency and thus provides for a transition from circuits having a high processing frequency to circuits having a lower processing frequency. <IMAGE>

Title: Circuit arrangement for improving the sound of loudspeakers
Inventor: KOJER KURT
IPC: H04R3/04
Filed: 1986-09-30
Abstract: The sound pattern of these loudspeakers is distorted due to a sound pressure curve which is nonlinear at least in part-areas of the frequency band. The circuit arrangement exhibits a parallel resonant circuit tuned to the nonlinear part-area of the frequency band of the sound pressure curve. The resonant impedance of the resonance circuit is set in such a manner that the part-area of the frequency band is damped in such a manner that the sound pressure curve becomes approximately linear in the part-area of the frequency band. To raise the sound pressure curve in the treble range, a series resonance circuit is provided which is tuned in such a manner that a power increasing with increasing frequency is supplied to the loudspeaker in the treble range.

Title: Arrangement for marking the compensation position in the case of measurements of optical path difference
Inventor: SCHOEPPE GUENTER
IPC: G01J9/02
Filed: 1986-12-22
Abstract: Arrangement for marking the compensation position in the case of measurements of optical path difference, which can be used as an additional unit in two-beam interference measurement arrangements, optionally of polarisation type or which operate using natural light.   The aim and object of the invention are to guarantee that the position which can be adopted using the compensators, which are present, or can optionally be used, in the measuring arrangements, and in the case of which the optical path difference of the object is compensated, is objectively displayed with a high sensitivity. It is impermissible for the image to be disturbed by additional structures. The technical and economic outlay is to be kept low. An arrangement according to the preamble of Claim 1 achieves the object in accordance with the invention by means of the features of the characterising part of Claim 1. The essence here is that in addition to the normally present measuring compensators an additional measuring compensator is inserted into the beam path. This additional compensator has a sufficiently uniform effect on the entire beam cross-section and continuously and periodically varies the effective path difference  DELTA  by +/-  lambda /8 </=  DELTA  </= +/-  lambda /4 given a fixed frequency. Furthermore, provision is made of a display device which displays the component of the signal voltage output by the receiver and in agreement with the frequency of the voltage which drives the measuring compensator.

Title: Accessory for toothbrushes having two brush heads
Inventor: NOERTHEMANN KARL-HEINZ
IPC: A46B9/04
Filed: 1987-02-04
Abstract: Toothbrushes having two brush heads for cleaning of the front and back of all the teeth, which have been known as oral hygiene brushes, are to be rendered adjustable via controllable brush pressure in order to adjust the cleaning gap between the two bristle-carrying heads. This requires an elastic ring and a deflection pin in the slotted handle. The brush pressure can be controlled on the handle part by pressing with the fingers during cleaning of the teeth in order to clean in a variable manner with a larger or smaller cleaning gap and the adapted brush pressure on teeth and interstices, for manual and mechanically operated double-head toothbrushes. The changed position of the cleaning gap can be indicated by sensors and an electronic system, for example an incandescent lamp or a digital display.

Title: Concrete paving stone for paved areas
Inventor: ROTH REINER DIPL ING
IPC: E01C11/22
Filed: 1987-12-18
Abstract: The invention relates to a concrete paving stone for paved areas, as a parallelepipedal stone (cut stone) or a stone of any desired shape, having vertical, preferably trapezoidal, toothing distributed over its peripheral surface, the toothing starting below the top surface of the paving stone and ending at the height of the foot. It possesses one or more deep-lying dummy joints in the top surface of the paving stone for receiving filling sand. The core of the invention consists in that, at the exit points of the dummy joints at the edge of the paving stone, the toothing is given a wider spacing at the peripheral surface and the vertical toothing is recessed in partial areas. A further embodiment requires that the dummy joint exhibits a gradient either starting from its centre and in each case ending at the edge of the concrete paving stone, or starting from one edge of the concrete paving stone and ending at the other edge of the concrete paving stone. The essential advantages consist in that a large-size paving stone in the laid state guarantees good surface-water drainage into the subsoil and, at the same time, a non-positive anchoring of the stones to one another is obtained.
