Patent DE-3022152-A1 (DE)
Title: Acoustic warning for automatic safety brake - with spring hydraulic servo cylinder controlling pneumatic hooter
Inventor: EIBL WOLFGANG
IPC: B60T17/22
Filed: 1980-06-13
Abstract: The automatic acoustic warning is for the automatic safety brake in a utility vehicle. It has a spring loaded servo cylinder (2) to monitor the brake supply pressure. If the pressure falls sufficiently to operate the hold off brakes then the servo cylinder operates a pneumatic valve (8) to operate the warning. The device is fitted to tractors etc. where trailers are often uncoupled. If the coupling is faulty the automatic brake operates. The servo cylinder operates a cam (4) which adjusts the pneumatic valve linked to the vehicle pneumatic supply, to operate the warning (10). The device is fitted on the rear wall of the cab.

Title: Rolling block for rolling wire and simple light sections
Inventor: HOEROLD GUNTER DIPL ING
IPC: B21B1/18
Filed: 1981-03-13
Abstract: The invention relates to a rolling block for rolling wire and simple light sections.

Title: Process for the sanitation of carbonatation sludges
Inventor: HILLEKAMP KLAUS DR
IPC: C13B20/06
Filed: 1981-06-16

In this case, according to the invention, use is made of the fact that the required electronics can be placed, for example, on a specially constructed printed-circuit board and can be installed with it in the installation socket in which the plug-socket insert is also located. Alternatively, it is furthermore provided for the electronics to be accommodated in the free space in a double or multiple plug-socket cover, value being placed on such a cover being mounted on only one installation socket.
Patent DE-3126621-A1 (DE)
Title: Method for preserving plant material
Inventor: ROBINSON RUTH A
IPC: A01N3/00
Filed: 1981-07-06
Abstract: The invention relates to a method for preserving cut plant material in which the particular plant material is immersed in a treating composition which is located in a pressure vessel and consists of glycerol, ethylene, glycol, diethylene glycol, triethylene glycol or mixtures thereof. The treating composition has a specific gravity (density) between 1.10 and 1.16. A suitable dye is added to it. The immersed or submerged plant material is subjected to a pressure which is higher than atmospheric pressure and is, for example, between 0.35 and 2.81 kg/cm<2>. This step takes place at ambient temperature and ambient humidity. The plant material is exposed to this pressure for a certain time so that the treating composition and the dye are absorbed. The length of time for this accordingly depends on the extent of the absorption. The material is then washed and subsequently dried under ambient conditions.
Patent DE-3137747-A1 (DE)
Title: Loudspeaker circuit with acoustic feedback
Inventor: KOCK GERHARD DIPL ING
IPC: H04R3/00
Filed: 1981-09-23
Abstract: The invention relates to a loudspeaker circuit for improving the reproduction of sound in the frequency range below 200 Hz. The object is achieved by using a loudspeaker circuit with acoustic feedback, the feedback signal being obtained by means of a microphone from the sound field in front of the loudspeaker. It is essential to the invention that the frequency response, measured in the free sound field, of the control loop which has been opened for the measurement is set in such a manner that it rises by at least 3 dB towards the low frequencies at least in the frequency range below 300 Hz within a spacing of one octave. This measure allows a sufficiently high gain to be selected for the control loop in order to effectively correct the interfering variables such as frequency response and noise of the loudspeaker and the reaction of the listening room on the sound field.
Patent DE-3139277-A1 (DE)
Title: Insect prevention device for doors
Inventor: BADEWIEN REINHARD
IPC: E06B9/52
Filed: 1981-10-02
Abstract: The invention relates to an insect prevention device for doors, having a protective net which is stretched out to cover the door aperture. Known insect prevention devices for doors consist of a rigid frame over which a protective net is stretched and which masks the door aperture in a folding manner, like a second door leaf. A rigid frame has the disadvantage that it is a bulky component which cannot be sold in retail shops and must be made in situ. The insect prevention device according to the invention is characterised in that a profiled rail which is pivotable in each case about a horizontal axis is articulated to attachment surfaces in the immediate vicinity of the door aperture, at least at the bottom and the top, in that a transverse edge of the net is retained on each profiled rail and consequently the net is stretched out between the profiled rails, and in that a flap restoring device which presses the profiled rails together with the protective net against the door aperture is provided. The advantage of this is that the profiled rails can be prefabricated and form, together with the protective net, a retail article in the form of a rolled-up package of minimum dimensions.
Patent DE-3142635-A1 (DE)
Title: Police guard shield
Inventor: KOCH KARL-HEINZ
IPC: F41H5/08
Filed: 1981-10-28
Abstract: In a police guard shield which is provided in its surface with an outwardly pointing inclined rectilinear curvature for receiving the user's arm holding the guard shield, the curvature having passing over it on the inside of the guard shield in its upper region a handle and in its lower region confronting the user's arm an additional arm holder which retains the user's arm in the lower-arm region, fatique phenomena as a result of static holding work caused by holding the shield are to be avoided. This object is achieved, according to the invention, in that the curvature for receiving the user's arm consists of two intersecting curvature portions (3, 4), for which there are, on the far side of the intersection point (20), two handles (5, 6) assigned to the parts (3a, 4a) of the curvature portions (3, 4) projecting beyond the intersection point (20) and, on this side of the intersection point (20), that is to say in the lower-arm region, two holders (7, 8) for the lower arm, the two curvature portions (3, 4) forming between them an angle of approximately 60 DEG  to 120 DEG . This ensures that the shield can be held by one or other of the user's hands or with both hands and, if appropriate, with the arms crossed. <IMAGE>

Patent DE-3210678-A1 (DE)
Title: Cable strip
Inventor: KRAUS WILLI
IPC: F16L3/137
Filed: 1982-03-23
Abstract: The invention relates to a cable strip, having a head part (1) and a loop part (2), the head part having two spread arms (6 and 7) in the insertion region (5) of the loop part (2), underneath which arms inclined tracks (9 and 10) are arranged which run obliquely and lead to the latching regions (8) of the head part (1). In this case, one inclined track (10) runs obliquely downwards and the other inclined track obliquely upwards, so that easy insertion of the loop part into the head part is made possible by interaction with the spread arms. A web (4) can be supported in the latching region (8) of the head part (1), which web (4) can be moved into the open position simply by pushing it out and returning it again, so that easy assembly, and also dismantling, of the loop part (2) with respect to the head part (1) is possible. <IMAGE>

Patent DE-3224499-A1 (DE)
Title: Cleaning device
Inventor: SCHULZ WALTER
IPC: A47L9/06
Filed: 1982-07-01
Abstract: A cleaning device is constructed as a suction nozzle for a vacuum cleaner, in which a brush is arranged in a housing between an upper housing wall and a lower slide plate. The brush can be adjusted for cleaning hard floor coverings in such a way that it projects downwards over the slide plate. Provided for adjustment is a lever-type switchover member which is mounted pivotably in the housing, projects with one lever arm over the housing for actuation and is hooked with the other lever arm into an opening in a lifting plate connected to the brush. When the switchover member is actuated, the lever arm connected to the lifting plate and the lifting plate are pressed against the brush such that the latter is displaced downwards counter to spring force over the slide plate. At the same time, the lever arm projecting upwards over the housing pivots downwards into a catch position relative to the housing. As a result of this catch position, the brush cannot be moved unintentionally, for example when the device is jolted, into the housing into its non-operational position.
