Patent DE-3806107-A1 (DE)
Inventor: BEHLING DIETER DR
IPC: C07C7/144
Filed: 1988-02-26
Abstract: A process is proposed, in which the air/permanent gas mixture (crude medium) is passed to a first gas separation membrane and is separated into a gas stream enriched in (permeate) organic compounds and a gas stream depleted of (retentate) organic compounds, in which the organic compounds are recovered from the enriched gas stream passed over a recovery apparatus. In the process the pressure of the primary air/permanent gas mixture is increased prior to entry into the first gas separation membrane and the pressure of the enriched gas stream is reduced after exit from the first gas separation membrane and the depleted gas stream leaving the gas separation membrane is released into the surroundings, a gas stream leaving the recovery apparatus being returned to the air/permanent gas mixture, after the pressure of this has been increased.

Title: Device for cooling a burner
Inventor: KOHLMANN HANS-ALBRECHT
IPC: F23M9/10
Filed: 1988-12-09
Abstract: In a burner with an elongated combustion chamber (4) which has fuel exit openings on its top side there are provided transverse to the burner axis cooling tubes (7) which extend between these fuel exit openings and are arranged extending obliquely to the horizontal in vertical planes. In a particularly advantageous way, the device can be a combustion chamber (4), surrounded by water which is to be heated, of a water heater.

Title: Speaking aid for laryngectomised patients
Inventor: AUGUSTIN HANS-ULRICH
IPC: A61F2/20
Filed: 1989-02-01
Abstract: The invention relates to a speaking aid for laryngectomised patients which represents a sound generator that can be fitted in the oral cavity by means of a fastening device and possesses operating elements which can be actuated in the mouth with the tongue or the hand and by which the oral sound generation can be switched on or off, as and when required, or controlled. Such a speaking aid has a low weight, requires little space and possesses high wearing comfort because the entire device is housed in the oral cavity. It can therefore be worn, for example, in a completely covered manner when engaging in sports. The speaking aid, according to the invention, can be cheaply manufactured with suitable electronic components because there are no energy losses due to transmission of sound energy or electromagnetic energy in the oral cavity.

Patent DE-3910011-A1 (DE)
Inventor: NITSCHE DIETRICH DR
IPC: A61K38/20
Filed: 1989-03-28
Abstract: Interleukin 2 promotes the natural elimination of endotoxins from the bloodstream by the body, particularly in cases in which an increased excess of endotoxins from the intestinal tract or from a septic focus can be expected following administration of an antibiotic and in cases in which elimination of endotoxins is diminished by a pathological disturbance of the organic function. Interleukin 2 is therefore suitable for adjunctive therapy to administration of bactericidal antibiotics.
Patent DE-3914889-A1 (DE)
Inventor: PODLESAK HEINZ
IPC: F15B15/14
Filed: 1989-05-05
Abstract: The working cylinder without piston rod is designed as a band cylinder, the band (3) in the cylinder covers (8) passing through a location chamber (10) for a sealing member and a guide member. The sealing member consists of a strip-like sealing element of elastic material on either side of the band, which sealing element can be designed as a lip seal on the piston side. The sealing elements (12, 13) are inserted into the location chamber (10) with elastic tensioning towards the band (3). The guide member arranged remote from the piston relative to the sealing member has a web-like guide element (23, 24) on either side of the band (3), which guide element (23, 24) is likewise pressed elastically against the band (3) by the tensioning of the sealing elements (12, 13). By means of stop surfaces (28), the guide elements (23, 24) end with a clearance gap (29) in front of the wall (15) of the location chamber (10). The result of this is that the band (3) can be elastically deflected from its desired position only by the clearance gap (29), positive-locking support of the guide elements (23, 24) on the cylinder cover (8) is then effected, and thus no further band deflection is possible.

Patent DE-3922862-A1 (DE)
Inventor: LANGE RUEDIGER DIPL ING
IPC: D07B3/06
Filed: 1989-07-12
Abstract: In planetary stranding machines, in which the rotor consists essentially of a supporting tube, to which disc-shaped supporting plates for the rotatably mounted bobbin carriers are connected, for purely constructional reasons the rotor cannot be designed with the necessary bending resistance, thus resulting here in limitations to the maximum permissible rotational speed which lead to a limitation of the production capacity. 
<??>The arrangement on the supporting tube (6) of longitudinal webs (7) directed radially outwards and distributed uniformly on the circumference affords a greater resistance which permits higher rotational speeds. Furthermore, if the supporting plates (12) on the one hand and the axes of rotation (13) of the bobbin carriers (9) on the other hand are arranged at an angle to the supporting tube (6), this produces a considerable reduction of the flight-circle diameter which in turn allows an increased operating speed, so that the production capacity can be increased.
