Title: Device for metering out pourable feed, especially for pig rearing
Inventor: BORNEMANN FRANZ
IPC: A01K5/02
Filed: 1981-05-08
Abstract: In the case of a device for metering out pourable feed, especially for pig rearing, having a feeding trough, a feed container arranged above the latter in the direction of gravity and a sealing element which can be moved by the mouth of the feeding animal and is situated between the feed container and the feeding trough, easy opening and closing of the outlet aperture of the feed container are to be made possible even for young animals and the said container is to need virtually no maintenance, to be easy to clean, to be precisely adjustable and to be economic to manufacture. This is achieved in that the sealing element (6) is designed as an element which is approximately L-shaped in cross-section and is arranged so as to be rotatable in the feeding trough (2, 3), standing on its head in the region of the longer (7) of the two limbs of the L, in such a way that the shorter limb (9) of the L releases an outlet aperture (11) of the feed container (12) when pressure is exerted on the free end (8) of the limb (7) of the L. <IMAGE>

Patent DE-3139049-A1 (DE)
Title: Cross-cut saw for cutting the side boards from tree trunks
IPC: B23D45/20
Filed: 1981-10-01
Abstract: A cross-cut saw unit (3) carrying a circular saw (4) with a horizontal axis of rotation is arranged laterally next to a feed mechanism for tree trunks (1). The cross-cut saw unit (3) is displaceable on a guide (6) which is tilted against the transport direction of the tree trunks (1). The guide (6) is attached to a frame (9) which is movable from a horizontal guide (10) transversely to the transport direction of the tree trunks (1). During the movement of the cross-cut saw unit (3) along the tilted guide (6), the circular saw (4) performs cross cuts (1') through the side board (1'') of the tree trunk (1). <IMAGE>

Title: Wide-angle hinge for the adjustment of a door-opening angle of 180 DEG  in relation to a cupboard sidewall
Inventor: DORN WILHELMINDE
IPC: E05D3/06
Filed: 1981-10-16
Abstract: The invention relates to a wide-angle hinge for adjusting a door-opening angle of 180 DEG  in relation to a cupboard sidewall. Known hinges of this type have the disadvantage of a relatively large hinge structure located in the interior of the cupboard and remaining here during opening; this is an obstacle to the constructive design of push-in fittings, such as drawers, etc. According to the constructive solution for achieving this object, the door pot part (4) is a carrier of the hinge shoe (5), there being provided in the hinge shoe (5) the guide grooves (14') and a guide pin (14) for a fork-shaped hinge arm (7) which receives the scissor-arm combination (8, 9). As a result of the functional connection between the hinge bearing (3') carried by the wall pot part (3) and receiving the central pivot axle (11), the parts assigned to the door pot part (4) remain on the door, so that, when the cupboard is opened, all the parts of the wide-angle hinge which project above the surface bear flat against the door. <IMAGE>

Title: Harvesting device for hop shoots
Inventor: KERSTEN JACOBUS GERARDUS
IPC: A01D46/02
Filed: 1981-10-23
Abstract: A harvesting device (11) for hop shoots (6) consists of clamping holders (15) which are mounted on a supporting frame (12), to be fastened to a loading truck (2) movable through the hopfield system, and into which the hop shoots (6) are to be introduced. These can be so clamped by the clamping holders (15), forming a V-shaped orifice, by means of undercuts that the guide wire surrounded by the hop shoots (6) can be torn off from the bracing wire as a result of the travelling movement of the loading truck (2). By means of the harvesting device (11), which can be produced in a simple way, it is thus possible to pick up hop shoots (6) in a short time, without great physical effort, and deposit them on the loading truck (2). <IMAGE>

Title: Method and chimney brick for constructing an inner lining in an open hearth
Inventor: FALKENBERG JANNIK
IPC: F24B1/195
Filed: 1981-12-01
Abstract: An inner lining for an open hearth is made from relatively thin chimney bricks made of refractory material, and the bricks are held together in the horizontal joints by tongue and groove connections, a metal band being used as tongue. As a result, bricking up of the inner lining, which instead is prefabricated, is rendered unnecessary. The invention relates to both a method and a chimney brick.

Title: Device for the sewing of straight and curved seams
Inventor: KUSS PETER DIPL ING
IPC: D05B29/10
Filed: 1981-12-18
Abstract: The device according to the invention serves for the sewing of textile sheet-like structures by means of a sewing machine. The object of the invention is to provide a specially designed press foot which is suitable for the sewing of both curved and straight contours, guarantees a uniform seam quality and can be produced at a low outlay. This is achieved, according to the invention, in that a rotatably mounted roller is fastened to a press foot having a plane press-foot sole. A suitable mechanism guarantees that, with the press foot lifted, the roller is pressed by means of a spring force onto the sewing material and, with the press foot lowered, it is raised slightly. <IMAGE>

Title: Device for bleeding line systems having a closed water circuit
Inventor: NOLTE EWALD
IPC: F16K24/04
Filed: 1982-03-01
Abstract: The housing of a device for bleeding line systems having a closed water circuit has a connecting piece for connection to the water circuit at its lower end and a valve at its upper end which valve has a valve pin which operates said valve and projects into the housing in an approximately horizontal direction, and on whose free end a float which moves in the vertical direction is suspended. The axial length of the housing is large enough that the valve is located in the air space above the water level at the maximum occurring water pressure. In order to ensure reliable operation of the device over a long time, the float (21) is connected to the valve pin (18) by means of a chain (20) which is long enough that it is clamped approximately in the region in which the float (21) is located at a level in the housing (1, 5) corresponding to the state of the water when there is no overpressure, or the water level falls below a predetermined level when the air space enlarges. <IMAGE>
Patent DE-3207910-A1 (DE)
Title: Closing device
IPC: E05B63/24
Filed: 1982-03-05
Abstract: What is provided is a closing device for a door, which has additional locking devices which are remote from the door lock and which are locked automatically during the closing of the door lock and are unlocked again within a predetermined period of time as a result of a multiple to-and-fro movement of the lock bolt over at least two closing operations. For this, the lock bolt (218) interacts with a position transmitter (272, 274) which is arranged in the lock plate (238) and which supplies different output signals in the two end positions of the locked bolt. These are checked in a correlation device (268) as to whether they succeed one another within a predetermined period of time, within which the movement of the lock bolt can occur only as a result of the proper actuation of the lock by the associated key. Drives (260, 262) assigned to the bolts of the additional locking devices are activated by the correlation device (268). <IMAGE>

Title: Camera stand with explosion-proof control
Inventor: MOELLER BERNHARD
IPC: F16M11/18
Filed: 1982-10-29
Abstract: A camera stand equipped with a mechanical rotary drive and assigned electrical valves permits a substantially increased range of use and monitoring concerning use in spaces at risk of fire and explosion, in particular use in underground mining and tunnel construction. The foot of the camera stand is arranged for this purpose in a housing and can be influenced via a mechanical rotary drive which, for its part, can be switched via assigned electromagnetic valves. In this case, use is made as rotary drive of a double-action pneumatic cylinder and a pivoting cylinder of, in principle, the same construction whose axis of rotation is influenced via the piston of the cylinder or pivoting cylinder. While the cylinder can be pivoted by 90 DEG  via the pivoting cylinder, which is installed in a fixed fashion, the corresponding foot of the stand, which is also pivoted, is rotated simultaneously or also separately from this by 360 DEG via the cylinder itself. In addition to high reliability, a correspondingly equipped camera stand is characterised by a low space requirement. <IMAGE>
