Title: Method and device for the manufacture of rod-shaped articles of the tobacco processing industry
Inventor: HELMS ADOLF DR DR
IPC: G01R33/30
Filed: 1983-04-09
Abstract: The invention relates to a method for the manufacture of rod-shaped articles of the tobacco processing industry, in which a filler material of at least one solid main component and at least one liquid additional component is made into a strand, the strand being cut into rods of predetermined length and the rods being continuously discharged. At preset intervals, a rod (2') is respectively automatically diverted from the continuous flow of rods (2), conveyed into the magnetic field of a nuclear magnetic resonance measuring device (12) and positioned there. To determine the proportion accounted for by a filler component, the rod (2') is subjected to a nuclear magnetic resonance measurement and then automatically removed from the measuring position. The measured values obtained by means of nuclear magnetic resonance measuring are used for quasi-continuous regulation of the proportion accounted for by a filler component. The method is particularly well suited for the determination and quasi-continuous regulation of the softening agent content of filter rods. <IMAGE>

Patent DE-3332664-A1 (DE)
Title: Emergency, stop, warning and safety device for motor vehicles with combustion engine
Inventor: ERLER KARL-HEINZ
IPC: B60Q1/52
Filed: 1983-09-10
Abstract: In its expanded equipment and improvement to parts of the main patent application P 3247065.7 the invention represents an innovation in motor vehicle engineering and an extension of the technical safety facilities for dealing with emergency situations which have hitherto not been included in technical safety measures. In the unanticipated event of the driver of a motor vehicle suddenly becoming unfit to drive and a resulting inability to avoid a possible accident, passengers in the vehicle, in the absence of any steering aid, are unable to assist or intervene because accelerator and brake pedals are generally blocked by the driver and arranged where they cannot be reached. By emergency striking of the button of a central control unit in the event of an emergency inside the vehicle the pedal functions can be disabled and the vehicle braked to a standstill with simultaneous switching on of warning devices. By the same action the functions necessary for braking and the warning devices are activated if a heavy impact acts on the vehicle from any direction. This is intended to largely prevent possible ensuing accidents and to avoid or mitigate the effects of further collision and impact. The interaction of all functional units is shown in the circuit diagram, sheet 1.
Patent DE-3340940-A1 (DE)
Title: Process and apparatus for improving mechanical defoaming
Inventor: ZLOKARNIK MARKO PROF DR
IPC: B01D19/02
Filed: 1983-11-11
Abstract: An annular chamber (8), open at the top, on the interior wall of a closed vessel (1) prevents the foam ejected by a defoamer (6) operating above the liquid surface from being repeatedly captured by the defoamer before it can mix into the liquid. The foam passes from the annular chamber (8) via pipes (9) into the liquid. In particularly intractable cases, the foam must be pumped from the annular chamber via a transport means into the liquid. <IMAGE>
Patent DE-3340952-A1 (DE)
Title: Filter
Inventor: YAGISHITA AISABURO
IPC: B01D29/39
Filed: 1983-11-11
Abstract: Since generally only a restricted space is available for mounting a filter, a filter is created having a maximum filtering surface in a restricted narrow space, the construction of which is simple and cheap and which, to remove sludge, can be easily dismantled and assembled. This filter has a filter material having a perforated core element, whose two surfaces are covered by filter cloth. The core element can be made from a semi-hard material having relatively low bending strength. The filter material is then formed into a perforated core cylinder or a perforated core web from which a multiplicity of arrangements can be composed such as a multiple ring arrangement on concentric circles having different diameter. By using the perforated core element to produce the filter material and a combination of filter cloth having a doubled surface area and perforated core element, a large filtration surface is obtained by means of which a low filtration rate can be realised. The filter thus created has an excellent filtration efficiency since a smooth path for the filter liquid is produced. <IMAGE>

Title: Device for use in the shield-type driving of an earth tube for moving the driving shield into a target shaft
IPC: E21D9/00
Filed: 1983-12-01
Abstract: Before a driving shield is moved into the target shaft, a pot-like housing (25) is fastened to the inside of the target-shaft wall (4), in which housing (25) an annular seal is arranged for the move-in gap of the driving shield. The housing (25), with a sleeve (14) of elastically deformable material, such as rubber, plastic or the like, in between, is balanced for weight and is attached to the target-shaft wall in a plane parallel to this wall. Guide plates (29, 30) inside the housing (25) ensure that the housing, already mounted before the driving shield is moved into the target shaft, automatically adapts itself to the position of the driving shield so that the seal reliably comes into effect. <IMAGE>
Patent DE-3346062-A1 (DE)
Title: Arrangement on the piston of an internal combustion engine and connecting device between piston and shaft of the internal combustion engine
Inventor: EICKMANN KARL
IPC: F02B75/32
Filed: 1983-12-21
Abstract: By means of the invention, middle parts are assigned to a twin-piston free-floating piston engine, between the two pistons and cylinders. The pistons and cylinders are spatially separated from one another by a mean distance but have the same axes and the two pistons have a common middle piston rod. In the space between the two pistons and cylinders, mechanical means are connected to the piston rod, by means of which either the reciprocating movement of the pistons is converted into a rotary movement or a plurality of such double-piston free-floating piston engines are compelled into a successive piston movement cycle. As a result it is possible to have the cylinders on the outside for the purpose of cooling, but the mechanics in the middle, and finally such central mechanics are proposed that there is no need for a complex crank shaft, or the overall unit is built so light that the engines are suitable for use in aircraft. An example of a multiple engine cylinder is also given. In a mathematical-geometrical analysis it is established that the constantly equal power of the engines and pump pistons of the older Eickmann patents is bound to lead to breakage of the hydraulic systems. Instead of this, the pump stroke must be arranged parallel to the shaft angle of rotation and for some applications an adjustable pump piston stroke must be provided.
Patent DE-3404554-A1 (DE)
Title: Method for adapting the inner space of a ski boot to the foot shape of the user
Inventor: KLEIN ALBERT
IPC: A43B5/04
Filed: 1984-02-09
Abstract: In order to make possible accurate guiding of the ski and nevertheless a comfortable fit of the boot, at least one flexible, airtight cavity filled with grains is provided in the ski boot. If ambient pressure or a pressure close to ambient pressure prevails in this cavity, the medium consisting of grains behaves similarly to a fluid and adapts to the foot shape of the user. By drawing off air which is situated between the grains, the flexible, airtight cavity is compressed by the ambient pressure. As a result, friction locking and positive locking arise between the individual grains. The medium consisting of grains rigidifies into a shape adapted to the foot of the user. By re-establishing the ambient pressure or a pressure close to ambient pressure in the cavity, the adaptable initial state of the medium is re-established.

Patent DE-3422365-A1 (DE)
Title: Device for determining rotational speed
Inventor: DORFMEISTER KARL DR
IPC: G01P3/486
Filed: 1984-06-15
Abstract: It has been known so far for the purpose of automatic detection of rotational speed to use tachometer generators which generate corresponding signals. These signals are frequently transmitted over large distances by means of screened cables, as a result of which the pulses to be transmitted are distorted in such a way that faulty information is produced. It is the object of the invention to avoid the above disadvantages. In accordance with the invention, the light beams emanating from the light source 1 are projected onto the optical fibre cable 3 via the lens 2a, the semireflecting mirror 7 and a further lens 2b. The beams reflected by the reflector 6 run back into themselves on the same path as far as the mirror 7, where they are deflected by 45 DEG , and are projected through a further lens 2d onto the light detector 8. It is preferable to arrange a perforated disc in front of the reflector 6. The signals modulated in this way are relayed via an amplifier 9 to the evaluation electronics 10 and appropriately processed from that point for the respective application. <IMAGE>
