Patent DE-3613708-A1 (DE)
Title: Quick-action coupling for the connection of agricultural working machines
Inventor: ALLWOERDEN WILHELM VON DIPL IN
IPC: B62D49/02
Filed: 1986-04-23
Abstract: The invention relates to a quick-action coupling for the automatic connection of agricultural working machines to the links of the tractor hydraulics and to the power take-off shaft connection of a tractor. A tractor-side connection frame (5), which has a mounting for the tractor-side portion (8) of the cardan shaft, is provided. The mounting consists of two blocking members (23) which are mounted on the connection frame (5) so as to be pivotably movable under spring effect about pivot axes (22) pointing in the direction of travel. The tractor-side portion of the cardan shaft is thus fixed in an initial position allowing automatic coupling, this fixing being cancelled automatically after the connection of the connection frame (5) to the appliance frame (7) has been made. <IMAGE>

Title: Apparatus and method for tracing local anomalies in the terrestrial magnetic field
Inventor: RUMP HANNS
IPC: G01V3/08
Filed: 1986-06-06
Abstract: Apparatus and method for tracing artificially caused local anomalies in the natural terrestrial magnetic field, as can be produced by metal inclusions, buried walls and trenches, caves, caverns etc. According to the invention, both the intensity of the terrestrial magnetic field and the alignment thereof are used for assessment. The natural fluctuations covering a large area are advantageously suppressed according to the invention by evaluating at least two sensors which are held at a distance from and oriented to one another by a rigid connection. As a result, the difference between the two sensors is a measure of the anomaly. By contrast with known methods, which use absolute measurement, the invention describes a relative method.
Patent DE-3623475-A1 (DE)
Title: Method and arrangements for identifying and recognising objects
Inventor: KAPPNER HELMUT A
IPC: G06K7/10
Filed: 1986-07-11
Abstract: In a method for recognising essentially rotationally symmetric objects, particularly containers which are provided with code symbols, the code symbols are arranged circularly around a centre as radial bars with a luminance factor differing from that of the environment. The area components of the circular ring occupied by the code symbols are independent of a value represented by the code symbols. The code symbols are scanned. A mean value is formed from the signals obtained by the scanning. The signals are binary-coded by using a threshold value which is derived from the mean value, whereupon the binary signals are decoded.

Title: Process for improving the energy efficiency of a baking line
Inventor: BEGE MARTIN DIPL PHYS
IPC: A21B7/00
Filed: 1986-09-15
Abstract: The invention relates to a process for improving the energy efficiency of a baking line which comprises a fermentation cabinet and a continuously fed baking oven, in which a heat recovery unit is employed. The aim of the invention is to develop a process by which the energy efficiency of a baking line can be significantly increased and in which the secondary energy recovered from the waste heat of the oven in the heat recovery unit can be optimally used in terms of economy with respect to the energy balance in order to keep the ratio "energy used per unit mass of bakery product" as low as possible. According to the invention this is achieved by the heat recovery unit preferably being started up simultaneously with the beginning of the initial heating phase of the baking oven and the steam obtained in the heat recovery unit being preferably completely utilised during the baking oven start-up process to adjust the temperature and dew point in the fermentation space of the fermentation cabinet until the operating parameters are achieved in the fermentation cabinet, and after the fermentation cabinet operating parameters are achieved, the fermentation cabinet operating parameters are maintained by the hot water generated in the heat recovery unit and/or some of the steam generated.

Title: Profiles at outer edge of counter-rotating rolls - are used to urge material inwards during compaction or crushing of solids
Inventor: FRANGENBERG MEINHARD
IPC: B30B11/18
Filed: 1987-02-05
Abstract: In the gap between them, a pair of counter rotating fundamentally cylindrical rollers horizontally ride by side, compact or crush descending solids, prevented from emerging sideways by retainer plates. To overcome the tendency for solids near the roll edges to be inadequately compacted/crushed, the edge regions of each roll have profiled zones (7) spaced at regular intervals round their periphery, pref. with cross-section decreasing towards the roll centre. The profiled zones may be welded beads of generally hemispherical cross-section, offset from the corresp. beads on the other roll. The beads may be at an angle to the roll axis, or replaced by a series of individual projections. USE/ADVANTAGE - For compacting salts, or crushing ores, coal, cement, clinker etc. Reduces need to separate and recycle incompletely treated material.

Patent DE-3713626-A1 (DE)
Title: Attachment for a lathe
Inventor: FRITSCH RUDOLF
IPC: B23G3/02
Filed: 1987-04-23
Abstract: In the case of a lathe attachment currently in use, the engaging and disengaging of the tool into and out of the cutting position must be performed by means of a hand lever. However, this calls for greater attention on the part of the lathe operator in order to achieve, for example, a thread termination of satisfactory quality. Only low lathe speeds or cutting rates can be used. In order to increase the working speed and improve the end of the cutting process in terms of quality, a cam is used to disengage and engage the tool, the cam being turned into the positions of disengagement and engagement by a drive and retained there. The novel attachment is suitable particularly for thread cutting.

Patent DE-3717287-A1 (DE)
Inventor: NYSTEN BERNHARD DIPL ING
IPC: A44B1/44
Filed: 1987-05-22
Abstract: The hollow tack button shank (21) was connected, in particular, to a shank end (24) which widens out in a bowl shape and has to cut a hole (19) in the web (10) of carrier material during the tacking process. However, said end must be compressed on the outlet side of the web of carrier material in a deformation chamber (15) of a counter-holding part (14) during the tacking process. In this case, there was always a tendency to use one type of tack button for webs of carrier material of different thicknesses, for which reason there was a long shank. This led to difficulties during tacking and tack button shanks breaking off. The wall of the tack button shank is provided with axially extending longitudinal zones which have a different strength relative to one another in relation to the dimensional changes occurring during the tacking process. This requires crinkling. <IMAGE>

Abstract: The propeller has at least two blades 1, 2 mounted on a hub 3 by means of fixings 4, the blades being curved such that the force acting on the surrouding air in a direction normal to the blade face and back surfaces results in a static pressure which rises towards the hub; also the centre of gravity of each propeller blade lies radially above the propeller blade fixing. The blades 1, 2 may be sickle-shaped when viewed in a plane normal to the propeller axis of rotation with the concave edge arranged in the direction of rotation. The blades may also be sickle-shaped when viewed in a plane containing the axis of rotation, with the concave edge arranged counter to the direction of thrust. There may be a mechanism for adjusting the blade inclination relative to the radial and/or axial directions. <IMAGE>
