Title: Steel band strapping unit - forms loop around object, cuts, bends and presses closure strip around band ends
Inventor: STANKOVICC-GANSEN MARYAN
IPC: B65B13/34
Filed: 1980-05-29
Abstract: The mechanism is intended for securing a steel strapping band (1) around an object. It comprises a band drive (A1), a band clamp (A3), a pressing (9,10) and cutting tool (8) assembly, and a movable band loop former (B), as in 2403261. A magazine (6) supplies closure strip material (4) to secure the ends of the band together by forming a sleeve around them. The strip material is fed through a passage (3) connecting with the band feed passage (2) upstream of a closure unit (A2). It is then laterally cut, bent and pressed around the band ends. Finally the strip material and band are cut through to sever them from their supplies.

Inventor: SCHINDLER ERICH DIPL CHEM DR
IPC: B01D71/56
Filed: 1980-07-25
Abstract: A membrane is disclosed of polyamide, a copolyamide or a mixture of polyamides, suitable for ultrafiltration and composed of an ultrafiltration skin and a backing layer. The pore size in the backing layer increases with distance from the ultrafiltration skin. The membrane is prepared by dissolving a polyamide in at least 75% formic acid, applying a casting solution, containing about 12-22% by weight polyamide and about 1-7% by weight polyethylene glycol in formic acid which has been brought to a temperature of below about 18 DEG  C., as a thin layer onto a carrier foil resistant to the components of the solution, introducing the casting solution on the carrier foil into a precipitation and washing bath, withdrawing the casting solution as a coagulated and washed membrane from the carrier foil, stretching in at least one direction and subsequently drying this coagulated and washed membrane.

Title: Ohmmeter with high and low ranges - uses measurement resistance changeover, divider, and high range potential divider
Inventor: FISCHER HANS-PETER
IPC: G01R27/14
Filed: 1980-09-02
Abstract: The resistance measurement device enables resistances in both low and high resistance ranges, i.e. approximately 0.1 milliohms to 200 kilohms and 50 kilohms to approx. 10 power 14 ohms, to be measured. It provides a directly proportional indication in both ranges. For the lower range a low resistance measurement voltage source is applied to a test resistance and a low resistance measurement resistor in series. The voltage drop across the resistors are input to a quotient circuit. For the higher range a high resistance measurement source is applied to the test resistance and a high resistance reference resistor in series and to a potential divider in parallel with them. The potential divider and the reference resistor provide the divider inputs. A range change switch connects either the low or high resistance measurement resistor in circuit.

Title: Carburettor for small IC engine - has connection from crankcase to fuel injection membrane for accurate mixture control
Inventor: ASHER DAVID MANLY
IPC: F02M17/04
Filed: 1980-12-05
Abstract: The carburettor has a fuel inlet (40) to a membrane pump (38,36,46) which delivers fuel through a needle valve (52) to a fuel chamber (60). A membrane (62) separates the fuel chamber from a dry chamber (74). The fuel chamber has connections to a main jet (75) and to slow running jets (76) into the main air passage (22). A channel (96,94) from the dry chamber (74) passes through a valve (26,92) in the throttle spindle to a connection (90) which is linked to the engine crankcase. The valve opens and closes with the throttle so that an accelerating impulse is given to the membrane as the throttle opens.
Patent DE-3049395-A1 (DE)
Title: Forming products of digitised analogue measurement signals - using asynchronous sampling and statistically constrained clocking time differences
Inventor: RUMPEL DIETER PROF DR ING
IPC: G06G7/161
Filed: 1980-12-29
Abstract: The method is for forming products of digital electrical measurement parameters derived from analogue signals by using clocked samplers and involves sampling the analogue signals at different points and forming the product at different time points. These products corresp. accurately to those which could be obtained from digital parameters obtained at equal points and synchronised times. The sampling of the analogue signals and the clocking of the product generators are performed continually at different time points. This results in a definable statistical error distribution for the differences in time of occurrence of the different digital measurement parameters falling within a measurement period. The measurement period is determined by the different clock cycles. The time intervals during the measurement period are constrained to exhibit a uniform distribution.

Title: Process for treating sulphuric acid which contains iron in the form of dissolved sulphate
Inventor: WILLMITZER HERBERT ING
IPC: C23G1/36
Filed: 1981-01-26
Abstract: A process is described for treating sulphuric acid which contains iron(II) in the form of dissolved sulphate, e.g. of sulphuric acid pickles or regenerating acids from cation exchangers loaded with iron(II) ions, which involves admixing a non-basic organic solvent which is completely miscible with water and has a lower boiling point than water, to precipitate iron(II) sulphate, and distilling off the solvent from the mixture with the sulphuric acid. In order to precipitate the iron(II) sulphate, the sulphuric acid in this process is mixed at a temperature of from 8 to 15 DEG , especially from 11 to 15 DEG , for from 1 to 4 hours with acetone in a volume ratio of from 5 : 1 to 1 : 1, in particular 3 : 1.

Inventor: SIEGEL HANS
IPC: E05F15/50
Filed: 1981-02-07
Abstract: A door-moving device is proposed in which an emergency valve (17) is provided with a lock (bar 20). Both working chambers (5, 6) of the working cylinder (4) which actuates the door (1) can be depressurised by means of the emergency valve (17) and the door can be actuated manually. The re-actuation of the pneumatic door movement can be carried out by the driver by means of a switch (23). So that the door (1) is not moved violently, a switching device (13) is used which is firstly effective in a choked manner but then allows the full pressure to pass to the working cylinder (4). The door-moving device is intended for public transport vehicles such as buses and trains. <IMAGE>

Title: Apparatus and method for changing stock rolls in a labelling machine
Inventor: PUTZER FRANK
IPC: B65H23/188
Filed: 1981-05-14
Abstract: An apparatus and a method for changing stock rolls in a labelling machine, in which a drive draws off a label-carrying carrier web from a first or second stock roll and feeds it to an intermittently conveying label dispenser, are indicated. So that the change can be carried out automatically and without an interruption in the labelling operation, a storage loop is produced between the drive (10) and the label dispenser (2). A cutting device (20) and a bonding device (30) are arranged in front of the drive (10), and a reversing drive (40) for the old and the new carrier web is seated between the cutting device (20) and each stock roll (50, 54). When the end of the old carrier web is detected, a control (60), by means of a drive (10), produces a maximum storage loop and terminates the advance of the carrier web in register with a new carrier web appropriately positioned beforehand. The control (60) subsequently triggers the cutting device (20), then the reversing drive (40) for removing the cut-off free end of the old carrier web, and then the bonding device (30) which bonds the end of the old carrier web in register with the start of the new carrier web. <IMAGE>

Title: Method for producing an electrooptical display device and a display device produced by same
Inventor: KRUEGER HANS DIPL PHYS
IPC: G02F1/1339
Filed: 1981-09-30
Abstract: In order to ensure the required plate separation with large-area displays, it is proposed to use a surface or relief printing technique to apply a distance point matrix to one of the two support plates. In a preferred embodiment, the pattern consists of two types of distance points: separation points which are fixed only on one of the two plates and prescribe the minimum separation, as well as connecting points which adhere to both plates and define the maximum separation. The starting material for the distance point is expediently a (selectively) UV-curable plastic. The production method proposed is particularly cost effective, provides substrate spacings that are very dimensionally accurate, and is suitable, above all, for liquid crystal displays having plastic support plates.
