Patent DE-3901663-A1 (DE)
Title: Apparatus for filtering, in particular for filtering out dust from a gas stream
Inventor: SCHMALHOFER MARKUS
IPC: B01D46/42
Filed: 1989-01-20
Abstract: The invention relates to an apparatus for filtering whose filter box (1), through which flows a medium to be filtered contains a filter device (13) which is provided with filter surfaces (15, 15', 15'') arranged at a distance from each other and offset and each covering a relatively large part of the cross-section of the filter box (1), so that the overall cross-section of the filter surfaces (15, 15', 15'') considerably exceeds the cross-section of the filter box (1) and simultaneously bypass orifices (25, 25' and 26, 26') are formed for the unfiltered and filtered medium respectively. Since the medium part-streams forming can each flow through the filter surfaces (15, 15', 15'') at a very low velocity, the risk is considerably decreased of dust particles being forced through the filter surfaces (15, 15', 15'') and the service life of the filter surfaces (15, 15', 15''), which is at any rate high because of the large overall cross-section, is further considerably increased. Cleaning nozzle devices (24, 24', 24'') are provided for counter-current cleaning of the filter surfaces (15, 15', 15''). The dust particles cleaned off pass into a collection vessel (23) without coming into contact with the filter surfaces (15, 15', 15''). Downstream of the filter device, an electrostatic precipitator (33, 33') and a fine filter (35) can be used. To generate flow as homogeneous as possible through the filter surfaces (15, 15', 15''), the medium is preferably [lacuna] by a ... Original abstract incomplete. <IMAGE>

Title: Process for fatliquoring and hydrophobicising leather and fur skins
Inventor: HOLLSTEIN MARTIN DR
IPC: C14C9/00
Filed: 1989-03-23
Abstract: Leather and fur skins are fatliquored and hydrophobicised (rendered hydrophobic) using sulphonated compounds of succinic acid with unsaturated fatty acids and their derivatives which, without addition of emulsifiers or solubilisers, possess sufficient solubility or emulsifiability in water. Preparation is by reacting the unsaturated fatty acid compounds with maleic acid and subsequent sulphonation. Treated leathers show reduced extractables and increased watertightness.

Patent DE-3919165-A1 (DE)
Title: Impulse heating to weld or cut plastics - by pressing between cooled contoured tools positioned opposite induction coils which are inside backing plate and connected to HF source
Inventor: SCHIRMACHER HEINZ
IPC: B29C65/38
Filed: 1989-06-12
Abstract: A tool for use with plastics, and particularly for welding and/or cutting, is impulse-heated by induction, as induction coil being inside the backing tool. Coating the tools used with PTFE is generally not necessary. ADVANTAGE - The process enables non-linear tools to be used i.e. to make e.g. curved welds or cuts. In an example, a top plate and its adjacent welding tools are both bored for coolant and are hence made of metal.  The bottom edge of the tools acts on the films to be welded along their suitable contour (or e.g. can be cutting edges).  The top plate is thus moved down to press the films against a plastic backing plate. Beneath the edges of the tools this lower plate contains an induction coil which, in this case, is flattened on its top face and is also bored for coolant. The coils are connected to the h/f generator. The tools are induction-heated under pressure which is maintained until the surface of the tools is below the m.pt.  of the film. This produces clean welds (or cuts).

Title: Setting optimum air-fuel ratio for engine with catalytic exhaust unit - using measuring probe in exhaust line having voltage curve with stoichiometric ratio of combustion air-fuel of lambda at unity
Inventor: VOGELSANG FRIEDRICH WILHELM
IPC: F02D41/14
Filed: 1989-06-23
Abstract: The voltage curve with an air-fuel ratio of lambda = 1 has a point of discontinuity, determined as a stable working point, and after the air-fuel ratio is regulated in a carburetted fuel line.

The fuel part supplied in the carburated fuel line increases about 1.25 per cent with an unaltered combustion air component, or with unchanged fuel component, the combustion air component is corresp.  reduced. During the operating phase a further output balance is not carried out. USE/ADVANTAGE - Lambda window has optimum combustion air ratio in range of lambda = 0.985-0.990 can be satisfactorily maintained reliably by simple means.

Title: Lock for sound proof door - includes sprung CAM to prevent being left open with lock bolt in extended position
Inventor: KAPOLNEK PETER
IPC: E05B63/18
Filed: 1989-11-08
Abstract: A door, especially a soundproof door, is provided with a lock which has a bolt (4) which is actuated by a cam (1). The cam is rotated by the door handle and moves away from the bolt so that the bolt spring holds the bolt in its socket to lock the door. The cam (1) is wedge-shaped and when in the locked position is wedged in a slot (2) in the lock housing. When the cam is rotated by the door handle it is withdrawn from the slot (2) and is acted on by the spring (3) which rotates it so that it acts on the bolt (4) to release the lock.  The bolt then remains in the retracted position and allows the door to be closed by remote control in the event of fire. USE/ADVANTAGE - Extra security in the event of fire.

Title: System for cutting fluid application in machining - has high pressure pump fed from charging pump to avoid entrapment of air
Inventor: WOLFF HORST
IPC: F16N7/38
Filed: 1989-11-08
Abstract: Cutting fluid is pumped by an immersion type charging pump (3) via a three-way valve either to a low pressure outlet or to high pressure pump (9) for delivery to a deep hole drilling tool during cutting. This ensures that high pressure fluid can be reliably delivered to the tool without the risk of admitting air to the system. Before entering the high pressure pump, the cutting fluid passes through a cooler (5) and filter (7).  During the non-cutting part of the cycle, cutting fluid can be directed through the low pressure circuit for general cooling and chip removal. ADVANTAGE - Simple method of ensuring delivery of high-pressure cutting fluid free of entrapped air.

Inventor: DIETZ HERMANN DR DIPL CHEM
IPC: G01N27/409
Filed: 1990-03-13
Abstract: A sensor element for an oxygen marginal current for determining the lambda value of gaseous mixtures, in particular exhaust gases from internal combustion engines, is supplied with oxygen by a short-circuit cell (5) located in front of the pump cell (9) of the sensor element.

Inventor: KAIS ALFRED
IPC: B61L5/10
Filed: 1990-05-04
Abstract: A device for locking a switch blade with a stock rail which includes a locking piece connected to the stock rail. The locking piece has an opening through which the longer leg of an L-shaped locking clamp extends. A switch element also extends through the opening and has an upper surface in contact with the longer leg of the L-shaped member which extends below the foot of the switch blade. The shorter leg has an end free to articulate with respect to a shaft. The shaft is further connected with a clamp receiver or clamp notch. The pivot axis of the clamp receiver member and shorter leg extends parallel with the switch blade and is positioned above the foot of the switch rail such that the clamp receiver member slopes downwardly between the shaft and connection point with the switch blade. This arrangement avoids tipping of the switch as the vertical force vector of the resultant vector passing through the contacting surface of the switching element and first leg intersects the switch blade rail foot on a supporting base immediately adjacent to the switch blade rail foot.
