Title: Method and apparatus for releasing cast clamping blocks from workpieces
Inventor: WENDT ULRICH
IPC: B23Q3/08
Filed: 1984-07-28
Abstract: The method for releasing workpieces (8) from cast or injected clamping blocks (7) into which they have been embedded in such a way for load-free holding during their machining on a grinding machine that the workpiece and the clamping block in each case form a clamping unit (6) and the surfaces of the workpiece (8) which are intended for machining lie exposed, the coefficient of thermal expansion of the material of the clamping block being higher than that of the material of the workpiece, consists in that the clamping block (7) is manufactured from a material which becomes brittle at a temperature characteristic of the material and that, after the machining of the workpiece, the clamping unit (6) is cooled at least until this embrittlement temperature of the material of the clamping block is reached, the clamping block breaking away from the workpiece due to the inner mechanical stresses which arise during cooling to the embrittlement temperature. <IMAGE>

Title: Device for controlling the position of a working implement articulated via a lifting mechanism on an agricultural working vehicle
Inventor: SCHWERIN GUENTHER
IPC: A01B63/111
Filed: 1984-10-05
Abstract: A device (39) for combined slip-and-pull control for a tractor (10) with an articulated plough (12) is proposed. The device (39) has a mixing appliance (33), in which the control deviations of the pull and slip are added in terms of their size and polarity in a mixing ratio preselected on a setting element (38), and a resulting control deviation is formed from this in order to control the raising, holding and lowering of the plough (12). Pronounced changes of ground resistance and friction between the driven tractor wheel (24) and the ground can be balanced out at a relatively low control frequency and control amplitude; the risk that the tractor (10) will become stuck in muddy ground is eliminated.

Patent DE-3446787-A1 (DE)
Title: Process for obtaining marketable mineral fertilisers
Inventor: HENRICH GUENTER DR
IPC: B01D53/74
Filed: 1984-12-21
Abstract: In the cleaning of flue gas, ammonium sulphate and ammonium nitrate are obtained in the form of a mixture. Since the molar ratio of this mixture of ammonium sulphate and ammonium nitrate varies considerably as a function of the fuels used in the combustion and the combustion parameters, it cannot be used and marketed as a mineral fertiliser without further treatment. Obtaining mineral fertilisers from these substances obtained during combustion processes in the waste gas is therefore relatively difficult and complicated. This object, however, is achieved according to the invention in a simple manner by separating the two components of the mixture by means of ammonia.

Patent DE-3504951-A1 (DE)
Title: Roller ski
Inventor: SCHIELE LUDWIG
IPC: A63C5/06
Filed: 1985-02-13
Abstract: Up to now, the ski rollers offered on the market for use on a solid floor surface have not managed to establish themselves, because they lacked the movement characteristics of a cross-country ski. The roller skis must be controllable, like conventional skis. Control must be possible by displacement and/or rotation of the body, without a ski being raised, as the latter action leads to a high degree of instability, which is true of a conventional ski as well. A roller ski must, like a ski on solid snow, be relatively resistant to tilting, which is achieved by means of the suspension under the wheel axles. The model described and illustrated in a drawing below can be controlled by means of displacement and/or rotation of the body as described above. The reaction regarding the change in the direction of travel is the same as in conventional skiing.
Patent DE-3505077-A1 (DE)
Title: Cutting machine for stem and residual timber
Inventor: PALLMANN WILHELM
IPC: B27L11/02
Filed: 1985-02-14
Abstract: The invention relates to a cutting machine for stem and residual timber for the direct production of splinter-free chip material with a low proportion of fine material. The cutting is effected inside a cutter rotor which is fitted with an interchangeable cutter ring and which can be moved together with its housing in a reciprocating manner in front of the orifice of a wood-feed channel provided with pressure elements. Located in the interior of the cutter ring is a compression chamber in which the timber to be cut abuts in sections against an abutment. In order to hold the pieces of timber immovably in position in a chatter-free manner, the compression chamber is provided with additional pressure elements acting transversely to the abutment, a fixed, slightly elevated entry threshold being arranged directly in front of the compression chamber. In order to prevent residual sections from getting into positions which are unfavourable for cutting, an axially displaceable baffle plate is provided in the compression chamber, and the pivot axes of the pressure elements are arranged in such a way that their pressure movement deviates only slightly from the cutter pitch circle.

Title: Procedure for reading data electronically, and invoice form for this procedure
Inventor: BOLZONARO LUCIANO
IPC: G06K1/20
Filed: 1985-10-01
Abstract: The operating personnel transfer the invoice data, using an entry keyboard, to a data processing system, which both prints a traditional invoice form and writes to a magnetic tape, which is attached to the invoice form, and on which all or part of the data of the corresponding invoice is recorded, depending on accounting requirements. The computer centre which acts for the company which receives the incoming invoice can then store all the data which is required for correct bookkeeping by directly reading the magnetic tape. The procedure makes it unnecessary for the responsible person in the company which receives the incoming invoice to enter the invoice using an entry keyboard. This saves considerable working time, and furthermore avoids the possibility of entry errors in the transfer of the invoice data.
