Patent DE-3218159-A1 (DE)
Title: Method for spraying wet concrete and preparation chamber for wet-concrete spraying machines
Inventor: BOMBELLI NINO
IPC: B28C5/38
Filed: 1982-05-14
Abstract: A method and an apparatus are to be provided, which allow wet concrete to be sprayed continuously and effortlessly under optimal conditions, even with regard to the quality of the sprayed concrete. For this purpose, the discontinuously produced concrete is processed to form a substantially continuous concrete stream. This concrete stream is fed to a pneumatic, at least approximately continuously operating conveying machine. Said processing consists in converting the concrete, which is produced in batches, by vibration into a continuous concrete stream. This is carried out in a preparation chamber having a concrete feeding pipe (3) and a conveying air feeding pipe (13). An unbalance vibrator (16) vibrates the concrete on a distributing floor (32) into an almost continuous, almost stationary concrete stream. The floor of the chamber (4) forms part of a cascade, a nozzle plate (36) impinged by compressed air being provided in the progressive ratio. The emerging compressed-air jets take hold of the concrete stream falling over the cascade, accelerate it and transport it pneumatically. <IMAGE>

Title: Roofrack for a motor vehicle
Inventor: TITTEL EBERHARD
IPC: B60R9/058
Filed: 1982-05-27
Abstract: A crossbar (9) can be fixed by means of locking screws (15) in approximately horizontal continuous sockets (8) of retention supports (1) which can be fixed on the roof of a motor vehicle. A travel limiting part (18) acts between the locking screw (15) and the crossbar (9). An end limb, projecting vertically downwards, of the travel limiting part (18) is designed to rest against the roof-side end (14) of the socket (8), preferably its bottom wall (10), while the other end limb (24), remote from the roof, is designed to engage with that end region (25) of the crossbar (9) which is remote from the roof. This ensures adjustment of the crossbar (9) up to a maximum overlap (a) at that end of the retention support (1) which faces away from the roof. Furthermore, by virtue of the special design, manipulation by unauthorised persons, at least by means of simple tools, is to the greatest possible extent reliably prevented. <IMAGE>

Title: Method of increasing the working load of mobile cranes
Inventor: EILER PETER
IPC: B66C23/74
Filed: 1982-07-29
Abstract: Up to now, cranes which are supported on the ground with fully extended outriggers (6a, 6b, 7) have been used for handling loads. To be able to pick up loads (9) located outside the area of the outriggers (6a, 6b, 7) and also put loads down outside the area of the outriggers (6a, 6b, 7), mobile cranes with greater carrying capacity had to be used, since they had to be operated with a greater working radius (L). So that larger loads (9) can be handled with a mobile crane of smaller carrying capacity, the outriggers (6b, 7) facing the load (9) and arranged on one side of the mobile crane are only partly extended in order to reduce the working radius (L). In order to increase the stability of the mobile crane for this case, additional counterweights (11a) are arranged on the mobile crane on the side remote from the load (9). <IMAGE>

Title: Device for the positioning and automatic control of movable machine units on coke oven batteries
Inventor: KRUEGER GERALD DR
IPC: C10B41/00
Filed: 1982-11-06
Abstract: When a coke oven plant is operated, the machine units (13, 14, 15, 16) which are movable along the coke oven battery and serve for the filling and emptying of the combustion chambers (11) which are arranged alongside of each other must be capable of being positioned very accurately. The invention therefore proposes a device for the positioning and automatic control of movable machine units in which reflectors (22) which mark the operating positions of the machine unit (13) are fastened along the coke oven battery. When the machine unit (13) approaches an operating position, the reflector (22) comes into the field of view of a television camera (25) which is fastened to the machine unit (13). Deviations of the reflector picture from a desired position which is stored in an evaluation unit (46) connected to the television camera (25) supply a measurement and control value which is used for the positioning of the machine unit (13). <IMAGE>
Patent DE-3243003-A1 (DE)
Title: Device for hooping coils
Inventor: KNIEPS HORST
IPC: B65B27/06
Filed: 1982-11-20
Abstract: The known device, in which a packing tape is passed round the coil with the aid of an arm which can be pivoted about the coil axis, has been improved by virtue of the fact that more than two packing tapes can be simultaneously passed round the coil, positioned with great accuracy. As a result of this, even very narrow coils lying next to one another, as are produced by slitting units, can be encircled at the same time. This simultaneous encirclement by a plurality of packing tapes is achieved by making the clamping device mounted on the pivotable arm extend over the full width of the coils and by dividing it up into a row, which is continuous over this width, of clamping elements which operate independently of one another and which can be unlocked from the clamping position by a common element and by mounting on the clamping device one or more guide devices for guiding the start of the packing tape, the broad face of which is sliding on the coil. The start of the packing tape is first pushed through the grooves of a pressure-exerting carrier, known per se, until it reaches the guide devices, which guide it into the clamping device. The pressure-exerting carrier, as is known, prevents the start of the coil opening as a result of internal stress. In addition, a pressure-exerting auxiliary device is mounted to press the packing tapes against the coil at points just in front of their ends, when the ends have been released by the clamping device, to allow the seal to be formed at the ends. <IMAGE>

Title: Device for tilting and locking the driver's cab of lorries
Inventor: ALDINGER HEINZ
IPC: B62D33/07
Filed: 1982-05-11
Abstract: The device for tilting and locking the driver's cab of lorries has a hydraulic tilting cylinder 1 in whose one feed line 6 which starts from the pump and is guided via a distributing regulator 9, there is provided, in addition to at least one hydraulically releasable non-return valve, a hydraulic cylinder which moves the locking element 23 with its piston. In the feed line 6 or the return line 15, a shut-off valve 14 is connected which is controlled by means of a control device 41 which is attached to the motor vehicle in such a way that, when the control device 41 is switched on, the shut-off valve 40 blocks the feed line 6 or the return line 15, as a result of which a circulation in the feed line/return line of the tilting cylinder can now no longer take place despite the pump being actuated. This has the advantage that, in order to prevent unauthorised actuation, the pump does not have to be attached to the motor vehicle at constructionally unsuitable points. <IMAGE>

Patent DE-3312847-A1 (DE)
Title: Eyelet, preferably consisting of plastic, which can be opened
Inventor: KRAMMEL ERWIN
IPC: F16B45/02
Filed: 1983-04-09
Abstract: An eyelet (1) which is like a spring safety hook and preferably consists of plastic has a closing limb (3) which can be pressed into the interior (2) of the eyelet against spring force and has on its end a hook by means of which it engages into a mating hook (5) of the eyelet clip (6), under tensile force. The inside of the hook (5) and the outside of the hook (4) additionally have a tongue and groove connection which prevents the closing limb (3) bending out of the eyelet plane. Nevertheless, when not subject to tension, the closing limb (3) can be bent back into the interior (2) of the eyelet without hindrance, so that it is possible to open the eyelet (1) quickly and easily for a cable loop or the like to be inserted or withdrawn. At the same time, despite the blocking of a bending-out movement of the locking limb (3) from the plane of the eyelet, weakening of this limb (3) or of the clip (6) is prevented as far as possible. <IMAGE>

Title: Means for changing the degree of light permeability, in particular of a greenhouse roof
Inventor: MEYER WILHELM
IPC: E06B9/24
Filed: 1983-06-16
Abstract: A means for changing the degree of light permeability - for example of the roof of a greenhouse - has at least two sheet-like elements, connected to one another in a gastight manner along their common edges, with a compressed-gas connection in the cavity between in each case two of these elements. The surfaces of at least two of the sheet-like elements are divided into alternating regions of good and bad degrees of light permeability. By means of a superatmospheric pressure which can vary between approximately zero and a positive end value, the elements can be brought into mutual abutment and to a specific mutual spacing-apart from one another, with the result that the passage of light changes between a minimum and a maximum value.
