Title: Plastics window frame members drilled for drainage - using tilting holder to set relative to fixed drill
Inventor: STELLWAG HEINZ
IPC: B23C3/30
Filed: 1974-06-14
Abstract: An apparatus for milling or drilling drainage slits or holes in plastics (or other) window frame members comprises a plate, to which the member is clamped, and a drill which can be moved perpendicularly to the axis of the member. The drill can be used to form two or more slits on different sides of the member, possibly at different angles. To achieve this, the clamping plate is pivotal in the fixed machine frame about an axis parallel to the axis of the frame member, this axis is equidistant (distance a) from the slit axes which are perpendicular to the longitudinal axis of the member, and the drill is at the same distance (a) from this pivoting axis. Thus, by simply rotating the clamping plate and frame member into succession of different positions and fixing it in each it is possible to bring the frame member into the correct setting in relation to the drill, so that each slit (or hole) can be formed in turn. Appts is simple and rapid to let up and use.

Title: Elastic suspension of electro-acoustical transducer - placed in hand-set of telephone leaving acoustically active side free
Inventor: MUELLER ERICH
IPC: H04M1/03
Filed: 1974-07-02
Abstract: The holder consists of a rigid component and a coaxial soft elastic component. The rigid component matches the outline of the housing area, so that the transducer capsule is correctly positioned, while its inner outline ensures a proper holding of the soft elastic component, which in turn provides an annular elastic supporting surface for the transducer holding the inserted capsule only by its lateral surface. The holder rigid component has at least one radial projection (6) or recess engaging the housing inner wall to fix the holder against rotation. Another asymmetrical projection (8) stretching in the axial direction serves to protect the connecting cord (9) against pulling forces.

Title: Probe for electrochemical determination of oxygen - in waste gases, esp. from IC engines
Inventor: KIRNER KUNO DIPL ING DR
IPC: G01N27/407
Filed: 1975-01-22
Abstract: In an electrochemical measurement probe for determining the O2 content in waste gases (esp. from internal combustion engines) by means of an O2 concentration bond having ion-conductive electrodes. On the surface of the electrode exposed to the waste gas an electron-conductive porous layer of temp. resistant material is applied, the novelty lies in the application of a porous coating to the electron-conductive layers, which coating is catalytically w.r.t. the adjustment of the gas equilibrium. The probe displays a sharp potential peak at the stoichiometric ratio, the probe has a short response and read-out time. close approach to thermodynamic equilibrium is assured by the relatively long path length of the gas through the catalytic outer layer,resulting in considerable accuracy.

Title: Balloon pessary for blocking fallopian tubes - is inflatable double balloon containing X:ray opaque thread in wall
Inventor: POPP LOTHAR DR MED
IPC: A61B19/00
Filed: 1975-08-23
Abstract: The balloon pessary closes the fallopian tubes for reversible sterilisation. It has an inflatable double balloon (1) which seals off the entrance to both of the tubes (3).

Title: Thermal separation of solids from waste water - by evaporation in heated collecting tanks
Inventor: HERPERS HUBERT
IPC: C02F1/04
Filed: 1975-10-14
Abstract: Method is carried out by evaporating the waste water in heated collecting tanks, to separate the solid and liquid constituents. The method may be performed in conjunction with utilisation of waste heat from refuse incinerator plants. Depending on the content of noxious substances, the steam which is given off is drawn off either directly or via gas scrubbers, and blown off into the atmos. The method may be used for process water in the electroplating, pickling and certain other industries, at low cost. As the solids content of these process waters is generally 10%, the quantity which has to be eliminated without pollution is considerably reduced. Sepn. is carried out in a single stage without the use of additional chemicals. The steam may be re-condensed and recycled.
