Title: Brushwood chopper
Inventor: SCHLIESING HANS
IPC: B27L11/02
Filed: 1981-04-29
Abstract: Brushwood chopper intended for towing behind or attaching to a transport vehicle. A brushwood chopper for chopping up brushwood consists of a brushwood-chopper device with entry opening and discharge bend and a motor drive. The brushwood chopper is mounted on or attached to a device which is carried by a transport vehicle with or without a loading space or attached device. Arranged between the brushwood chopper and the device is a rotary device which enables the entry opening of the brushwood chopper to be optimally orientated in accordance with the respective requirements. So that the discharge bend remains orientated in the direction of the transport vehicle when the device is rotated, a differential mechanism is provided which is formed from toothed rims, sprockets and chains and causes the discharge bend to swivel in the opposite direction to the device. Furthermore, the discharge bend has a means which permits the top part of the discharge bend to rotate even when the device is secured. This means consists of a collar fastened to the bottom part of the discharge bend and a collar fastened to the top part of the discharge bend. Both parts rotatable towards one another can be fixed by means of a pin pushed through holes into the collar.

Title: Press for producing beams or sheets from glued rods
IPC: B27M3/00
Filed: 1981-05-26
Abstract: In order to produce beams or sheets, so-called lamellae, from individual glued-together rods in a quick, cost effective and safe manner, a press which is provided with an end face pressing device and a lateral pressing device is combined with a feeding device. While the previously introduced rods are pressed in the press until the glue or the like produces bonding, the next stack is being prepared in the feeding device and is then preferably introduced by means of a driven push-in device when the press receptacle is once again unoccupied. It is possible to operate in an especially efficient manner when at least two, but preferably four individual presses are combined to form a rotor press, so that the stack of rods can be introduced, for example into the fourth individual press, at the same time as the glue is producing bonding in the first three individual presses. In order to be able to produce profiled beams, for example so-called casement wood, from which window casements can later be made, the pressing surfaces of the transverse supports, which together form a counter-holder, and of the pressing supports, which together form the lateral pressing device, can be provided with profiled sections, a two-part design with insertable profile strips being advantageously selected.

Title: Device for lifting road cover caps
Inventor: BERGAN THILO
IPC: B66F19/00
Filed: 1981-08-08
Abstract: A device for lifting road cover caps (cover caps) is described which has a hook which can be hooked into a web of the cover caps and exerts a pull on the cover cap by the application of force to the device. According to the invention, the device has two supporting feet which are connected via a cross yoke and of which at least one consists at least partly of a lifting device, the hook being fastened to a point which is also raised when force is applied to the lifting device. With a device of this type, very high forces can be applied to the cover caps, often rusted in place, so that these cover caps can be lifted safely and reliably, even if they are severely rusted up with the cover into which these cover caps are inserted. The device can readily be used by one operator without having to smash the cover caps, as was the practice hitherto. Consequently, the cover caps are reusable, which saves considerable costs.

Title: Device for regulating the temperature of a building and building element for use in such a device
Inventor: RANNOCH HERMANN DIPL ING
IPC: E04B1/76
Filed: 1981-12-08
Abstract: The invention relates to a device for regulating the temperature of a building, in which a heat transfer medium flows through building elements forming a unit with the masonry and/or the ceilings, floors and/or the roof surfaces and stores in it thermal energy which would otherwise be transmitted to the outside as energy loss. As a result, the heat transmission to the outside is greatly reduced. After flowing through the collectors (1) of the building elements in a heat exchanger or a heat pump (WP), the excess thermal energy, which is used for regulating the temperature of a building, is removed again from the higher-energy heat transfer medium. The low-energy heat transfer medium is again supplied to the collector (1) of the building elements, so that the circuit is closed. With the device according to the invention, use is optimally made on the one hand of the energy of a heat energy carrier, because the irreversible transmission through the masonry (2) is greatly reduced, and on the other hand cooling of the building interior, with simultaneous utilisation of the ambient heat for hot-water preparation, is also possible at summer temperatures. <IMAGE>
