Patent DE-2006309-A1 (DE)
Title: Sewing machine for stitching upholstery
IPC: D05B11/00
Filed: 1970-02-12
Abstract: The machine consists of a sewing bridge, with sewing unit and a transversely movable stitching carriage with a template and a support frame for the upholstery. Via a drive, a scanning unit moves template and stitching carriage along a path determined by the template. The carriage has an associated dragging carriage for the upholstery in front of it. This moves the stitching carriage synchronously via an intermediate automatic control unit. The control unit has a control plate on the stitching carriage, the plate edges having associated light barriers from radiation sources and receivers on the dragging carriage. Electric motors work with the interruption of the light barriers by the control plate. The machine is for stitching upholstery, esp. upholstered mats, covers, and mattresses.

Title: Thin thermoplastics tube mfr. by external suction - around extruded tube resulting in better operational control than with internal blowing
Inventor: REIFENHAEUSER HANS
IPC: B29C48/08
Filed: 1972-12-06
Abstract: Thermoplastic is extruded from an annular die into a tubular form which passes to a venturi where it is thinned out, and then between rollers where it is flattened into a sheet. Internal and external cooling systems are provided for the extruded and thinned tube.

Title: Skip with hinged rear wall - has one side of supporting chain on wall to swing it open by reaction of skip
Inventor: BECKS HERBERT
IPC: B60P1/16
Filed: 1973-10-06
Abstract: The skip is slung on chains between two pivoted arms on the rear of the skip lorry and can be dropped onto ground by swinging the arms over. The end walls of the skip are fitted with flaps for dropping in the load. The rear end of the skip is hinged about a top transverse axis with the rear end formed by the rear wall and sections of the side walls. If the bottom edge of the skip is secured on the lorry during tipping, the skip is tilted. One end of each chain sling is secured to the flap end so that the flap is opened during tipping by the action of the weight of the skip. This enables loads to be discharged without obstruction.

Title: Connecting rod used in internal combustion engine - made of plastics preferably reinforced with glass fibre
IPC: F16J7/00
Filed: 1973-12-04
Abstract: The rod is particularly for coupling a crankshaft to a piston, and is made of plastics preferably reinforced by glass fibre.

Title: Dyeing piled fabric by applying dye powder to the pile - and after hot fixing removing excess powders by eg. washing or suction
Inventor: EIBL JOHANNES DR
IPC: B41F15/42
Filed: 1974-02-12
Abstract: A pile fabric is dyed by applying dye powder onto the pile of the advancing fabric pref. via a mask advancing with the fabric so that dye powder is only applied to selected regions of the pile, and then fixing the dye pref. by passing the fabric beneath a heater. Excess dye powder which has not been fixed is subsequently removed by e.g. washing or suction and pref. the pile is finally brushed up. The method is used for dyeing piles of synthetic, hydrophobic fibres, e.g. polyamide, polyester, polyacrylonitrile, polyurethane, polyolefin, cellulose, triacetate, good quality dyeing is achieved of fibres which are inherently difficult to dye.
Patent DE-2407481-A1 (DE)
Title: Oil tanking line distribution system - has slide casing which controls flow between distributor pipe and tap line junction
Inventor: SKIBOWSKI HUBERT
IPC: B65B39/00
Filed: 1974-02-16
Abstract: A distributor pipe freely connected to the main supply line is adapted in inside and outside diameter at its free ends to suit the lines serving as tap pipes from the distributor. A slide casing round the distributor pipe can be slid into an outer position where it projects beyond the pipe end and thus seals onto the free end of the associated tap pipe end when this has been aligned with the free or issuing end of the distributor pipe at this point. Preferably the slide casing is designed as a piston which is loaded at both ends by pressure medium and is sealed condition within a cylindrical annular space surrounding the distributor pipe. The interior of the space should be formed by the outside of the distributor pipe itself.

The outermost wall is connected at its base to a dished end which is mounted on a hollow shaft protruding through, and connected to, the base of the outer shell through a bearing. The rotor is driven by an electric motor. The equipment is suitable for evapn., distn, drying and degassing of substances requiring a short contact time. The rotor is rigid and does not therefore run out of balance through flexibility.
Patent DE-2408888-A1 (DE)
Title: Electro-static air filter - with non-conducting filter medium coating on the electrodes and zig-zag profile
Inventor: JUNG ANTON L DIPL ING
IPC: B03C3/155
Filed: 1974-02-23
Abstract: Electrostatic air filter comprises a series of mutually spaced filter elements capable of being charged-up electrically, but in which the filter elements consist of an electrically conducting layer covered on one or both sides with a mat of non-conducting material. The design of the filter elements and their assembly, which must be a compromise between the requirement for electrostatic precipitation and air filtration gives improved results compared to the usual electrostatic filters in which the dust once deposited on the electrodes is then retained only by mechanical forces and tends to be re-entrained in the air stream.
Patent DE-2411784-A1 (DE)
Title: Determination of diethylene glycol in polyethylene tere-phthalate - after hydrolysis in aq. soln. with alkaline earths
Inventor: GLAMANN HARTWIG DR
IPC: G01N30/06
Filed: 1974-03-08
Abstract: Samples for gas chromatographic(GC) determination of diethylene glycol content of polyethylene terephthalate (PET) are prepared from a suspension of 5g. finely-ground polymer, 10 ml. water and around 0.1 g-equiv. alkaline earth hydroxide, by partial hydrolysis under reflux for around 20 mins. followed by neutralising the warm soln. with CO2 and filtering. Dissolution time of the polymer is reduced from over 16 h., allowing results to be obtained in time to modify the polymerise. process. Applicn. of pressure during hydrolysis is unnecessary and the alkaline catalyst is ppted. by CO2 instead of passing into the filtrate where it can cause blockage of GC columns.

Al cpds. used for forming catalyst are those where R = ethyl or isobutyl gp. The concn. of the soln. of catalyst pref. ranges from 0.1-2%. The treatment of the polymer gel with the soln. of catalyst takes place at temps. from -30 degress to +30 degrees C under stirring or forced circulation. The polymer gel is dissolved under the action of the catalyst and is removed from the reactor as a soln.

Title: Spray screen washer for motor vehicles - has spray nozzles that retract into bodywork and are forced out by valve
Inventor: STUMPEL JOSEF
IPC: B60S1/52
Filed: 1974-04-13
Abstract: The Design overcomes difficulties where variations in washer fluid can affect the pressure applied to the system and also that small drops of water can be sucked back and pollute the cleaning fluid. The principle of the washer is that under the effect of pressure, a movable nozzle is forced out of a retracted porition into the working position. Directly near the spray outlet there is a valve that achieves this movement. It can act dependent on pressure or can be a magnetic valve. It is made from a tube fitting in a second tube of larger cross section and both tubes are sealed by a coupling bellows. There is a rubber return spring pad inside the tube.

Title: Testing device for filled plastics bottles - has sealed bottles compressed between belts for pressure monitoring at reject point
Inventor: KALLENOWSKI PETER
IPC: B65B57/00
Filed: 1974-05-09
Abstract: A bottling plant for filling flexible plastics bottles with a gaseous drink has a bottle testing station to test for leaky or incorrectly filled bottles, with the filled and sealed bottles delivered by a belt conveyor into the space between a pair of horizontal belt conveyors with their belts on edge, i.e. parallel to the sides of the bottles, which gradually converge, so that the sides of the bottles are compressed, there being a row of vertical rollers behind each belt. At the end of the converging gap is a pressure measuring device which emits a pulse when an over or under pressure is registered, so as to actuate a reject device which removes the incorrectly filled bottles from the flow of bottles before they are passed to a take-off conveyor.

Title: High-speed railway train lavatory - has suction hood formed by paired wind ducts and compartmented interior
Inventor: BRINK HEINRICH
IPC: B61D35/00
