Patent DE-3308737-A1 (DE)
Inventor: DRAUZ KARLHEINZ DIPL CHEM DR
IPC: C07C37/60
Filed: 1983-03-11
Abstract: The known nuclear hydroxylation of phenol with organic solutions of hydrogen peroxide in the presence of a catalyst is carried out in improved manner by employing both (1) a special, practically water free solution of hydrogen peroxide in an organic solvent which forms an azeotrope with water, which azeotrope boils below the boiling point of hydrogen peroxide, and (2) sulfur dioxide as a catalyst. Through this, the nuclear hydroxylation is substantially simpler than previously; difficult separations, e.g., from water-phenol, or the separation and recovery of the catalyst are eliminated. Besides, the yields are increased.
Patent DE-3309279-A1 (DE)
Title: Potato-planting appliance
Inventor: LOHFF BERNHARD
IPC: A01C9/08
Filed: 1983-03-11
Abstract: The invention relates to a potato-planting appliance, by means of which seed potatoes are dropped automatically into the furrow at specific intervals. Appliances of this type have hitherto had a construction involving a high outlay and have constituted special vehicles designed for this purpose and have therefore been economical to purchase only for larger agricultural concerns. The object on which the invention is based is to provide a potato-planting appliance which is of extremely simple construction and which is so light that it can be coupled, for example, to the drawbar of a plough, so that the seed potatoes fall into the furrow immediately after the latter has been opened up. This object is achieved, according to the invention, by means of a funnel-shaped receiving container opening into a vertical downpipe, in front of the outlet orifice of which rotates a bucket wheel, the shovel blades of which block the outer orifice, the bucket wheel being so driven by means of corresponding extensions of a running wheel that, after a respective rotation of the bucket wheel through 90 degrees, the lowest potato located in the downpipe is ejected, and the downpipe is opened on its rear side by a two-armed lever which is pivoted by the bucket-wheel wing acting on its lower end.

Patent DE-3313539-A1 (DE)
Title: Filter unit
Inventor: BRUKER OTTO
IPC: B01D35/12
Filed: 1983-04-14
Abstract: A filter unit is described, the unit elements of which comprise a filter and, assigned to this, a manually or automatically switchable control valve for a medium to be filtered, for example oil, which elements are so designed that the individual modules can be assembled in the modular system, the filter unit itself, however, also acting as a module for combinations of a filtration plant. The control valve is mounted in the wall of a filter housing and is activated via a cylinder vent-valve construction by means of an internally or externally used control pressure. A non-return valve which can be unblocked is assigned to the filter and acts to reverse the filter unit. The filter unit is constructed so that by means of appropriate connection pieces a plurality of filter units can be combined to give multiple filter plants, that is both next to each other and linked together vertically.

Title: Suspension device for an exhaust system of a motor vehicle
Inventor: KRAFT FRANZ DIPL ING
IPC: F01N13/18
Filed: 1983-06-22
Abstract: In the case of a suspension device for an exhaust system of a motor vehicle, supporting parts are rigidly fixed to the vehicle body and to the exhaust system respectively. The two supporting parts are connected in the vertical direction by a flexible supporting ring. Between the supporting parts, there is provided around this supporting ring a thrust ring which tightly and elastically encloses the latter and interacts with the supporting parts. The supporting ring can be easily mounted on the supporting part of the vehicle body. The thrust ring can then easily be pushed on to the supporting ring against the supporting part from beneath, clamping elastically. The second supporting part to be detachably connected to the exhaust system is laterally inserted into the supporting ring and then comes to bear with its bends on the thrust ring, so that lateral oscillating movements of the exhaust system are prevented.

Title: Anti-jack-knife brake device, especially for motor vehicles
Inventor: MERTENS FRANZ
IPC: B60T15/12
Filed: 1984-03-01
Abstract: In a vehicle train comprising tractor vehicle and trailer, a device serving for the staggered actuation of the trailer brake system is integrated in the handbrake valve of the tractor vehicle. This device serving for anti-jack-knife braking has an anti-jack-knife piston (39) controlling the connection to the vent aperture (21) of the handbrake valve and the connection to the trailer control valve (25), which piston is connected by means of a drive carrier (bow 37) or similar actuating member to the actuating element (35) which can be rotated by the rocker arm (1) of the handbrake valve. By swivelling this rocker arm (1), first the trailer brake system and then the brake system of the tractor vehicle is rendered operative, a threshold force preferably being predetermined for actuation of the rocker arm, which makes it obvious to the user of the handbrake valve when the braking system of the tractor vehicle comes into operation. <IMAGE>

Title: Process and device for sucking off fibre fly collected on a filter
IPC: D01H11/00
Filed: 1984-03-15
Abstract: In the process and device for sucking off fibre fly collected on a filter (18) of a cleaning appliance (11) for textile machines, there is a suck-off station (12) having a suck-off channel (33) which can be introduced into the suction space (15) of the cleaning appliance (11) in order to suck off the fibre fly collected on the filter (18). To remove the fibre fly completely and uniformly, the suck-off orifice (35) of the suck-off channel (33) is moved across the filter (18), whilst the closing member (36) for the suck-off orifice (35) is introduced with a constant lead into the interspace (19) underneath the filter (18) and thus cuts off the main flow from the suction space (15) to the interspace (19) or to the fan wheel (20), before the suck-off orifice (35) reaches the respective region of the filter (18). <IMAGE>

Title: Window wiper, in particular for motor vehicle window wiper systems
Inventor: BAUER KURT
IPC: B60S1/40
Filed: 1984-04-13
Abstract: The invention relates to a window wiper having a connecting element for coupling a wiper blade to a wiper arm. The connecting element is arranged so as to fit between the side elements of the carrying clip for the wiper blade and engages in bores in the side elements with bearing pins which are arranged coaxially with respect to one another on lateral guide elements. The guide elements bound with their sides lying opposite one another a receptacle channel for the end of the wiper arm. The receptacle channel intersects the axis of the bearing pin. As a result, undesired slipping of the bearing pins out of the bores is prevented because the end of the wiper arm supports the guide elements in the region of the bearing pins.

Abstract: A condenser for heat pumps is disclosed. The condenser has an outer pipe (1) conducting refrigerant, with, directed perpendicularly to its axis, an inlet connection piece (2). Arranged in the outer pipe (1) are water-conducting pipes (3 and 4). The water-conducting pipes (3) lie directly opposite the filling connection piece (2) and contain water which is to a great extent free of scale deposit, such as for example the water of a heating circuit. The water-conducting pipes (4), with in each case a connection (5), are arranged at a distance (a or b) from the inlet connection piece (2), which results in a cooling of the refrigerant along the water-conducting pipes (3) lying opposite the filling connection piece (2) to a value which is 60 DEG C at the most. The water-conducting pipes (4) serve mainly for conducting water, in the case of which increased scale deposit is to be expected above 60 DEG C. <IMAGE>
