Title: Working stage with swivel segments
IPC: E21D11/40
Filed: 1984-05-26
Abstract: Provided for use in underground mining and tunnelling is a working stage with a working platform, which can also be changed in its shape in the front area in such a way that tight bearing of the front edge of the working platform against the heading face is guaranteed in each case. Consequently, a working platform of this type can at the same time be used as a means of securing the heading face so that additional elements are dispensed with. So that the front part of the working platform can be changed in each case, swivel parts are attached there which can be swivelled via swivel cylinders about a pivot lying approximately centrally. The front edge of the working platform is bevelled while maintaining a shorter, straight centre piece. <IMAGE>

Title: Device for the stepwise setting of the speed of a work shaft, in particular that of wood-working machines
Inventor: PANHANS ANTON GUSTAV
IPC: F16H9/12
Filed: 1984-06-01
Abstract: The device for the stepwise setting of the speed of a work shaft (6), in particular that of wood-working machines, has a drive motor (1) which can be switched on and off and a work shaft (6) situated at a distance from the motor shaft (2) and driven by a V-belt drive. The V-belt drive is formed by a continuously variable V-belt mechanism (3, 4, 5) or P.I.V. variable speed mechanism. A setter (11, 12, 13; 22) is assigned to this mechanism. There are a plurality of presetters (21) for predetermined speed values of the work shaft (6), the said presetters determining the respective position into which the setter of the mechanism can be adjusted by hand (22) or in a driven manner (13). <IMAGE>

Title: Conveying system for printed products with built-in distributing device
Inventor: STIEFEL WERNER
IPC: B65H29/62
Filed: 1984-07-03
Abstract: The invention relates to a conveying system for printed products which exhibit a relatively low degree of elasticity, e.g. folded sheets, pamphlets and inner books, which conveying system contains a distributing device, by means of which the products are guided onwards in one of two conveying systems arranged downstream so that products which have been collated in a defective manner can be separated out. To achieve this, a conveying system for products exhibiting a low degree of elasticity must be devised which operates without interrupting the drive. The object is achieved in that deflection rollers for inner driving means are arranged on bearings which are eccentrically offset in relation to one another and in that deflectors which can be pivoted through the angle  beta  are situated on a common distributing device support, preferably on a shaft. <IMAGE>

Title: Serial tetrad addition and subtraction device in BCD 8421 code with negating-complementing circuit
Inventor: MERKLE PAUL
IPC: G06F7/50
Filed: 1984-07-06
Abstract: The object of the invention is a tetrad addition and subtraction device in BCD 8421 code, which has:     - as the main circuit, a dual tetrad adder (1) - as the correction circuit, a subtraction circuit (2) to subtract the number 6 - a pre-adder circuit (3) to add the number 6, by which the number 6 is added to the summand at the A inputs when addition takes place - for carrying out additive subtractions, a negating-complementing circuit (4), which is a 15s-complement circuit for BCD 8421 coding. Thus, in this addition and subtraction device, additions are carried out normally, and subtractions by additive subtraction. For subtraction, the B inputs are the minuend inputs, and the A inputs are the subtrahend inputs. For addition, in circuit (4), the complement bypass is pre-triggered, and the pre-adder circuit (3) is pre-triggered. For additive subtraction, in circuit (4), the complementing is pre-triggered, and the pre-adder circuit (3) is not pre-triggered. <IMAGE>

Title: Magnetic filter insert for the removal of magnetisable constituents from suspensions and liquids
Inventor: KALTEIS HANS
IPC: B01D35/06
Filed: 1984-08-29
Abstract: The insert of the invention can be used wherever magnetisable constituents have to be removed from liquids or suspensions. The aim of the invention is the design of a magnetic filter insert whose cleaning is possible without great labour or apparatus cost, and the danger of mechanical destruction of the matrix elements is to be prevented. The invention describes a simple apparatus according to which the matrix does not have to be broken down into its elements for cleaning, and its destruction is precluded. The matrix elements of the magnetic filter are arranged in a matrix container. The container walls are permeable to suspensions and liquids; the container floor represents an element supporting the matrix elements, and can be constructed as a ring or a holding claw, or as a perforated, grid or slatted floor. The matrix container consists of material with perforations, expanded metal, fabric or bar material. Spacers can be situated between the matrix elements. The main field of application is the elimination of strongly magnetic impurities from ceramic slips.

Title: Hydrant, in particular underground hydrant
Inventor: GRAEDIG MARLIS
IPC: E03B9/08
Filed: 1984-09-28
Abstract: The hydrant has a pillar which exhibits a standpipe connection and contains a vertically adjustable valve rod. A shut-off valve is present at the lower end of said pillar, which valve exhibits a water-pipeline-side valve seat, with an axial seal seat surface and a valve body which is acted upon by closing forces. The valve body is guided with limited vertical displaceability on the valve rod and can be pressed by said rod, in the region of an axial seal surface, against the seal surface of the valve seat. In order that the hydrant is tightly connected in a reliable manner to the water pipeline, even in the case of a pressure compensation of the pillar interior, a further radial seal surface, which tapers on the water-pipeline side, is present in addition to the axial seal seat surface, and the valve body exhibits a radial seal bead which engages with said radial seal seat surface even before the closure of the axial seal.

Title: Method and apparatus for removing cross-sectional restrictions of a hollow cylindrical body, preferably a pipe ready to be laid
Inventor: WILLMS FERDINAND
IPC: B21D1/08
Filed: 1985-07-24
Abstract: A method for removing cross-sectional restrictions in a hollow cylindrical body, preferably a pipe ready to be laid, for example a dredging pipe for dredging work, the said restrictions having been caused by deformations, e.g. dents and the like. The method is intended, in particular, for the removal of the cross-sectional restriction at the site in open country where the pipe is to be laid and is distinguished by the fact that the pipe from which the dent is to be removed is connected to a second pipe arranged in parallel with it, in that a tool situated at the end of a turning rod and having pressure members which can be laid against the inner wall of the pipe is set to the cross-sectional width of the pipe and inserted into the end of the pipe, the pressure members being laid against the inner wall of the pipe, and in that the turning rod and hence the tool are turned and simultaneously moved in the longitudinal direction of the pipe. The use of a vehicle, in particular an agricultural tractor, as a drive for turning the turning rod by way of a power take-off connection of the agricultural tractor and for moving the turning rod and the tool in the longitudinal direction of the pipe by the driving action of the tractor is particularly advantageous.
