IPC: E01C19/10

Granted: 1993-02-17
Abstract: A drying and mixing plant for producing a bituminous paving mixture comprises a drying and mixing drum (10) which is supported by a hydraulic cylinder (16) or other lifting means so that the inclination of the drum axis may be altered. By choosing a suitably small angle of inclination so that the drum inclines downwardly towards its outlet end, the plant may be used for continuous operation, so-called drum-mixing. Aggregates and other components may then be supplied continuously to the inlet end of the drum from silos (18), through a center intake (24) from another source (25) and binder such as bitumen may be supplied through a supply tube (58). Finished paving mixture is continuously discharged from the outlet end of the drum and passed to a product silo (28) via a conveyor (27). Alternatively, if the drum axis is arranged substantially horizontally, it is possible to treat two or more substantially separate material portions of different compositions in the drum (10) at the same time in so-called batch-mixing. By tilting the drum (10) by means of the cylinders (16), the material portions may be transferred from one drum section to the next after a certain time of treatment, and finished paving mixture may be discharged as a total portion from the drum section adjacent to the outlet end of the drum. The discharged mixture portion may possibly be further treated or be mixed with further materials in a mixing apparatus (30), to which the mixture portion is passed by means of a conveyor (29). The same plant may thus optionally be used for continuous production of large amounts of a paving mixture of the same composition or for batch-wise production of small asphalt amounts of the different compositions.

Title: Device for demolishing chimneys
IPC: E04G23/08
Filed: 1989-11-01
Granted: 1992-01-15
Abstract: An arrangement for the demolition of smokestacks includes a demolition tool for successively demolishing the smokestack shaft. A work platform is suspended from the smokestack wall by suspension devices distributed over the circumference of the work platform. Each suspension device includes at least one vertically guided lowering piston which can be locked in different vertical positions. A suspension arm is mounted at the upper end of each piston and can be swung inwardly and outwardly. In the outwardly swung position, the suspension arm engages over the smokestack wall. A mechanical shovel with the demolition tool works on the work platform. The demolition is carried out in the area of a suspension arm which is swung inwardly. After the demolition work has been carried out, the suspension arm is again moved to the outwardly swung position. This is repeated with all suspension arms until the work platform can be lowered by the stroke of the lowering piston and a new demolition cycle can begin.

Abstract: A central processor interrogates concentrators via line trunk groups for temporarily stored data successively in a cyclic sequence. In each of the concentrators, it is monitored whether the time interval between in each case being interrogated and next being interrogated exceeds a predetermined time limit value. When the time limit value is exceeded, the relevant concentrator continuously repeatedly reads the data out of its store and transfers them to the central processor. Concentrators are set up for interworking with the central processor and with line trunk groups of in each case a relatively old and relatively new type of construction. The extent of the data to be transmitted on the basis of being interrogated depends on this. The concentrator stores the type of construction feature. When the time interval is exceeded, the temporarily stored data are transmitted as determined by the type of construction feature stored in each case. <IMAGE>

Abstract: 2.1 Due to the increasing number of communication means present in a car, the need has arisen for these to be combined so that a plurality of these sources can be in operation without interfering with one another, and for the space required to be reduced. 2.2 This is achieved according to the invention in that a car radio has interfaces for other communication means, i.e. external sources, at its disposal, where incoming signals are processed in the AF signal processing component of the car radio and control of the processing operation is taken over by the car radio microprocessor. This control includes the switchover of the AF signal processing to the external source when a signal arrives here, and the automatic presetting of volume, tone and fader for the external source. 2.3 Broadcast receivers, in particular car radios. <IMAGE>

Abstract: The invention relates to a device for the manufacture of stranded conductors by Roebel transposition of profile wires with a rectangular cross-section with a guide for the profile wires conveyed in two parallel stacks. The device is formed from side parallel guide surfaces and latches, which are offset through 90 DEG  with respect to said surfaces and one of which is provided per stack, the two latches being located diametrically opposite one another and being displaceable in parallel, in opposing directions, cyclically, and of slides which can move at right angles to the longitudinal extent of the stranded conductor for displacement in opposite directions of in each case one profile wire from a (lacuna) on the adjacent stack, while bending the profile wire. The slides are supported opposite one another in the other diagonal, in the same way as the triggers. The device furthermore comprises a control device for synchronisation of the cyclic operation of the drives for displacing the triggers and slides. The invention is characterised in that each slide (5) has allocated to it on the opposite side of the stranded conductor an opposing holder (8) which is offset with respect to the slide in the conveyance direction (9) of the stranded conductors and is supported displaceably in the opposite direction thereto, at right angles to the stranded conductors, and is driven in synchronism with the movement of the slides and triggers. <IMAGE>

Abstract: What is described herein is a solution feed, slurry precipitation polymerization process for making copolymers of maleic anhydride and an alkyl vinyl ether within a predetermined viscosity range. The process of the invention is characterized by precharging a large excess of the alkyl vinyl ether in a reactor, feeding maleic anhydride dissolved in a minimum amount of an organic solvent into the precharged reactor, and polymerizing the monomers in the presence of a free radical initiator. The copolymer product then appears as a pumpable slurry in the reaction medium. The slurry is discharged from the reactor and the desired copolymer is obtained therefrom as a fine, white powder having specific viscosities in the range of about 1.5-6.0, and preferably about 2.6-3.5.
