Patent DE-3202132-A1 (DE)
Title: Apparatus for using the waste heat of, in particular, heating boilers and for ventilating rooms
Inventor: VIESSMANN HANS DR
IPC: F28D21/00
Filed: 1982-01-23

Patent DE-3204147-A1 (DE)
Title: Hydraulic multi-step and differential gear transmission in motor vehicles
Inventor: STIEVE KONRAD
IPC: B60K17/10
Filed: 1982-02-06
Abstract: The essential characteristic of this transmission is a plurality of gear pumps driven by the engine. These are connected by the pressure line to the hydraulic drive on the vehicle axle. Should a gear pump press the drive fluid onto the pressure line it acts non-positively, but if the fluid flows ineffectively back into the intake line this results in idling on the pump in question. The drive fluid is controlled by way of a switch system. The more pumps press the drive fluid onto the pressure line, the faster the drive is forced to turn. The number of pumps corresponds to the number of speed stages. So that a vehicle can travel and be braked in reverse, the intake and pressure line lead by way of a rotary switch. Depending on the setting, the rotary switch can block the drive fluid (vehicle braking) or shift in the reverse direction (reverse gear). The hydraulic brake system can also be used separately in the case of other types of transmission.
Patent DE-3204458-A1 (DE)
Title: Crank gearing for cranks actuated by muscle power
Inventor: ETTIG WOLFGANG
IPC: B62M11/14
Filed: 1982-02-09
Abstract: In order to achieve an approvement in efficiency of heavy physical work according to physiological principles in crank gearings actuated by muscle power, in particular in bicycles, the directly transmitting crank gearing is replaced by a crank gearing with an infinitely variable transmission dependent on the angular position of the crank in order to make the angular velocity of the crank variable. The infinitely variable change in the transmission ratio is achieved technically by the fact that the output force is transmitted to an output wheel mounted on the crankshaft by a disc cam which rotates on a shaft which is attached to the crank, is axially parallel to the crankshaft and rotates with the crank around the latter. In order to ensure this planet-wheel-type rotation of the disc cam, the disc cam is rigidly connected to a gearwheel running on the same shaft, which interacts with a non-rotating gearwheel surrounding the crankshaft centrically and revolves around this gearwheel.
Patent DE-3206480-A1 (DE)
Title: Carriage guide
Inventor: LAHME KARL ING GRAD
IPC: F16C29/04
Filed: 1982-02-23
Abstract: The invention relates to a carriage guide in which the roller bearings are arranged in the corners of a rectangular quadrilateral, the longer side of which extends in the direction of the guide rail. The guide rail can be of unlimited length. The working speed and acceleration far exceed the values permissible with recirculating ball elements. Due to the arrangement of roller bearings in pairs one above the other, no additional bending forces arise due to the rolling-contact bearings and the conventional cast parts of the carriage guide can be kept extremely light by the use, which is possible of plastic. <IMAGE>
Patent DE-3210448-A1 (DE)
Title: Quick-release nut
Inventor: WARKOTSCH HORST
IPC: F16B37/08
Filed: 1982-03-22
Abstract: The invention relates to a quick-release nut, especially for the attachment of a vehicle wheel to the mounting shaft of a balancing machine. The quick-release nut has two threaded segments which are supported in a body such that they can rotate, are pretensioned, are approximately semicircular and can move radially. In order to achieve an installed height which is as small as possible and also to make said nut applicable to a large number of thread diameters of different size, the threaded segments can each pivot about a rotation axis parallel to the mounting shaft, which rotation axes are arranged in two adjacent ends of the threaded segments, and the quick-release nut has securing elements for locking the threaded segments in the tightened state. In order to release the threaded segments, the other two adjacent ends are inclined so that a wedge-shaped recess is produced into which a wedge-shaped compression piece can be moved in order to spread the segments. The threaded segments are pretensioned with the aid of a leaf spring or two compression springs which partially engage around them. Oblique surfaces as well as a stop on the body and the segments, steps, and rollers which can move in the annular gap between the threaded segment and the body are provided as the locking means. <IMAGE>

Patent DE-3225973-A1 (DE)
Title: Fail-safe pneumatic spring
Inventor: SCHREIBER WINFRIED DIPL ING
IPC: F16F9/02
Filed: 1982-07-10
Abstract: The invention relates to a fail-safe pneumatic spring, in particular for engine bonnets and/or boot lids of motor vehicles, in which a retention device acting in the retracted position of the piston rod is provided which is operative after a predetermined retraction travel of the piston rod into the cylinder and prevents an automatic extension movement of the piston rod. Such a retention device is intended to prevent the pneumatic spring from representing an additional safety risk in the event of deformation of parts of the vehicle due to an accident. According to the invention, the intention is to further develop such a pneumatic spring by arranging in the piston head a hollow, the area of which, projected into the plane of the piston head, is at least as large as the cross-sectional area of the piston rod, and by a correspondingly shaped projection projecting from the cylinder head, which projection, when the predetermined retraction travel has been reached, covers this area in sealing fashion within the hollow.

Patent DE-3300891-A1 (DE)
Title: Heating element
Inventor: LESCHKE WERNER
IPC: F24D13/02
Filed: 1983-01-13
Abstract: In a floor heating system, heating elements are laid on the base material. Each heating element has heating conductors for heat production, and leads run from each heating element to the mains supply. Especially in the case of large rooms with many individual heating elements, this results in a large bundle of electrical leads.   The invention provides a remedy for this, in that the heating elements are equipped with connecting sockets at their opposed ends, so that adjacent heating elements can be connected together electrically. The hitherto conventional separate leads to the mains supply are thus omitted, and instead only one further lead is required according to the invention. The new heating elements have a peripheral stepped rebate, so that adjacent heating elements overlap or are overlapped, and form a mechanically stable joint after being screwed down. Moreover, the heating elements are formed by glass fibre- reinforced concrete slabs of relatively small thickness, and can also be laid later on a floor, without a screed.

Title: Telemetry system for radiating projectiles
Inventor: FRAISSE HANS DIPL ING
IPC: F42C13/04
Filed: 1983-05-05
Abstract: This telemetry system can be used for determining speed and spatial separation from the target object of projectiles equipped with an electromagnetic radiation source. The system contains three sensors which are arranged along the line connecting the firing site and the base point of the target object in the vicinity of the target. Each sensor has two main characteristic directional areas which are perpendicular to one another and one is very wide and the other one is focused very narrowly. If the projectile flies through the main characteristic directional areas of the three sensors, the sensors supply a sensor signal which depends on the speed and the path of the projectile and on the distance and position of the sensors with respect to the connecting line between firing site and base point of the target object. Speed and spatial separation of projectiles from the target object can be determined from the succession in time of these sensor signals and the starting signal on firing.

Title: Process and apparatus for producing animal feed, in particular complete feed for horses
Inventor: PLANK GOTTFRIED
IPC: A23K50/00
Filed: 1983-10-28
Abstract: An apparatus (1) which is suitable in particular for producing animal feed such as for example complete feed for horses, is equipped with a press device (5) the press unit (7) of which forms a combination unit which includes a mixing device, a cutting device and also a press. As a result of this design of the press device (5), it is possible to mix the feed components supplied from feed containers (2, 3, 9) in the course of supplying them to the filling opening (13) of the press unit (7) and, during the pressing, simultaneously to cut the roughage constituents to the desired length. Preliminary cutting of the roughage can be dispensed with here, which has the additional advantage that the roughage can be cut to a precisely defined length without the danger in this case that any precut roughage is shortened in the course of pressing to undesirably short lengths. It is thus possible using the apparatus (1) according to the invention and the process according to the invention to produce animal feed which has a very high feed quality without any expensive production measures being necessary for this. <IMAGE>
