Title: System for the production of fibrated concrete slabs and process for operating the system
IPC: B28B1/52
Filed: 1981-11-26
Abstract: The invention relates to a system for the production of fibrated concrete slabs. The basic construction comprises a charging frame, a slab press, a discharging frame and a manipulating carriage which can travel over the slab press between charging frame and discharging frame. The manipulating carriage has longitudinal running tie bars which, at the beginning of the charging position, extend over charging frame and slab press, at the end of the discharging position, extend correspondingly over slab press and discharging frame. The said carriage is equipped with manipulating devices for receiving and setting down elements of the pressed product, in each case made up of a pressing underlay and a fibrated concrete mat. The charging frame and the discharging frame are double-deck frames. The slab press is a double-deck press. The manipulating carriage correspondingly has two manipulating decks with manipulating devices in the form of clamping mechanisms or the like. The charging frame additionally has a lifting mechanism with grippers, with the grippers of which an element of the pressed product introduced into the charging frame by means of a conveyor can be grasped and raised above the level of the upper charging deck into a waiting position. This makes it possible during the course of an operating process for the system to move a first element of the pressed product into the charging frame, grasp it with the grippers of the lifting mechanism and raise it into the waiting position, while the manipulating carriage is positioned ahead with its half on the charging frame side in the opened slab press. Thereafter, the manipulating carriage with its half on the charging frame side can be moved into the charging frame and the element of the pressed product in the waiting position can be transferred by the lifting mechanism to the manipulating devices of the upper manipulating deck, while in addition a further element of the pressed product is also introduced into the lower manipulating deck. Thereafter, both decks of the slab press are discharged and charged. <IMAGE>

Title: Method for transmitting frequency-modulated sound broadcast signals via a digital broadband distribution network
Inventor: HESSENMUELLER HORST DIPL ING
IPC: H04J3/04
Filed: 1982-03-08
Abstract: A frequency band comprising m frequency-modulated sound broadcast signals (FM1 to FMm) (in Fig. 1) and with a lower limit frequency (f1) and an upper limit frequency (f2) is sampled according to the invention in an analog/digital converter (A/D) at the sampling frequency f0 = 2(f2-f1), is coded with n bits and transmitted as a bit stream (BS) 1 = n x f0 bit/s via a digital broadband distribution network (KTV). A frequency transformation takes place due to the sampling so that, following the conversion of the bit stream (BS1) in a digital/analog converter (D/A), a pulse-amplitude modulated signal PAM is produced whose main power component lies between 0 Hz and f0/2. With its input stage which acts as a bandpass filter, a conventional FM receiver (FME) filters out the upper band or lower band of a harmonic of the sampling frequency f0 and processes this signal band without additional frequency conversion as a frequency division multiplex signal comprising m frequency-modulated sound broadcast signals. The attenuation of this signal band received by the FM receiver is equalised through appropriate drive of the digital/analog converter (D/A). <IMAGE>

Title: Expanding dowel with an expanding sleeve and an expanding part which can be displaced with respect thereto
Inventor: OTT JOHANN DIPL ING
IPC: F16B13/06
Filed: 1982-03-22
Abstract: An expanding dowel, which consists of an expanding sleeve (1) and a bolt-shaped expanding part (2). The expanding part (2) has a plurality of expanding cones (7) which are arranged in a row one behind the other and engage on the inner wall of the expanding sleeve (1) in order to anchor the dowel on the correspondingly conical inclined surfaces (8). In the unspread state of the dowel, there is a distance (a), which becomes increasingly larger counter to the insertion direction of the dowel, between the expanding cones (7) and the inclined surfaces (8). During the spreading process of the dowel, the expanding cones (7) thus run successively, that is to say first the expanding cone (7) on the side in the insertion direction and then the respectively successive adjacent expanding cone (7), on an inclined surface (8). In consequence, the spreading increases and hence also the radial compression stress towards the insertion end of the dowel, which governs the level of anchoring. <IMAGE>

Title: Feed dispenser for feeding feed masses, tending to form bridges, to pigs
Inventor: WESSJOHANN HUBERT
IPC: A01K5/02
Filed: 1982-04-14
Abstract: The invention relates to a feed dispenser for feeding feed masses, tending to form bridges, to pigs, having a feed storage container with bottom discharge openings which is arranged above the feed trough. The object on which the invention is based is to improve a feed dispenser from which the animals feed themselves in such a way that the formation of bridges in the storage container by feed masses tending to do this is avoided. According to the invention, provision is made for each discharge opening to be assigned a shaking grate, and for each shaking grate to be operatively connected to an actuating element penetrating into the feed trough. This has the advantage that blocked discharge openings in the storage container can no longer occur even with moist and sticky feed masses, since animals set the shaking grate in motion with the actuating element as soon as feed masses stop slipping through the discharge openings.

Title: Installation for adjusting the desired value in heating or cooling control loops
Inventor: KROPF BERND DIPL ING
IPC: F25B41/04
Filed: 1983-05-27
Abstract: The invention relates to an installation for adjusting the desired value in heating or cooling control loops. In particular, the invention relates to an installation for attaining and maintaining specific operating temperatures in cooling units such as cooling racks and the like. The invention is based on the object of creating an installation by means of which it is possible to achieve continuous variation in the desired value, in a simple manner, without directly modifying the conveyor system of a heating or cooling system. It is also intended to ensure that the evaporator temperature continuously assumes the maximum value in order to keep the amount of condensation forming on the outer wall of the evaporator low and hence to prevent or to reduce icing of the same, which reduces performance. This object is achieved according to the invention in that a heat source is allocated to the temperature sensor of the control loop, the temperature of which heat source can be varied continuously via an adjustable controller, as a result of which the control device of the control loop remains switched on for the time which is required to reach the intrinsic system desired value, irrespective of the current instantaneous actual value.
Patent DE-3321742-A1 (DE)
Title: Drive unit for a lifting device which can travel over stairs
Inventor: HUMBERT KARL HEINZ
IPC: B66B9/08
Filed: 1983-06-16
Abstract: When travelling over stairs with the devices which are currently in use, continuous, jolt-free conveyance of materials for transport is not ensured. This disadvantage can be eliminated by a drive unit consisting of a blade wheel which is assigned to the stairs and a transmission connected downstream thereof. The three-blade blade wheel rotates as it is driven about its centre point, in each case one blade of the wheel rolling over one step of the stairs. The central point of the wheel describes here a flat curved path similar to a cycloid which is repeated from step to step. This curved path is converted by a transmission, which is connected downstream and primarily converts movements, into a linear path parallel to the angle of inclination of the stairs. The lifting device serves to maintain a load platform in a horizontal position for any materials for transport during the movement over stairs without guidance systems on the part of the building. Of course, it can also be used by people in wheelchairs so that they can travel over stairs while sitting in their wheelchair without any aid from accompanying persons.

Title: Method and device for checking the readiness for use of inspection machines
Inventor: BRUDER HARALD R
IPC: B07C5/12
Filed: 1983-07-07
Abstract: Inspection machines are preferably designed as rotary machines and are provided with a testing device through which the bottles to be tested pass. This testing device may come to react differently in the course of time, and so that it is necessary to check all functions at a specific time interval and, if necessary, to make an appropriate readjustment. To this end, a method for bottle inspection machines with one or more testing heads is proposed in which, during otherwise normal operation, test bottles are fed instead of the bottles to be tested within a predeterminable repeatable time period, and the bottles are delivered to a separate test bottle track regardless of the direction in which the bottles are normally conveyed further, and are once again held in their readiness for use position in this track.
