Title: Low loss overhead electric rail - with parallel supply rail joined to rail in sections
Inventor: BOPP KARL DR ING
IPC: B60M3/00
Filed: 1975-02-18
Abstract: The overhead electric conductor (2) is divided into sections of equal length by cross-connectors (5, 6, 7) which connect the conductor to a main supply cable (3). The main supply cable carries most of the current, with the impedance of the two cables chosen so that the lower impedance main cable connects the current flow to the relevant section of overhead cable by two cross conductors. The overhead conductor cable is thus only under heavy current in short bursts. The main supply cable (3) is coaxial, with an outer earthed sheath and is either a ground line or a support cable for the overhead line.

Title: Alkali aluminosilicates used as builders in detergent compsns - treated with tartaric acid or its salts to improve wettability
Inventor: ROEBKE WOLFGANG DIPL CHEM DR
IPC: C11D3/00
Filed: 1975-03-12
Abstract: Surface of ion-exchanging crystalline alkali aluminosilicates used as builders in washing, cleaning or rinsing compsns. is rendered hydrophilic by mixing the alkali aluminosilicate with up to 30 wt. % of tartaric acid and/or its alkali salt(s), drying and grinding. The tartaric acid or its salt(s) can be introduced in the form of an aq. soln. Suitable alkali aluminosilicates are zeolites of the A, X and Y types; the alkali can be Na, K or Li. Alkali aluminosilicates are capable of exchanging the alkali ions for Ca2+ and Mg2+ thus exerting a water-softening effect. They can be used for this purpose in washing, cleaning or rinsing compsns. instead of the objectionable phosphates, under the condition that their wettability is improved by a surface treatment such as described above (otherwise their action is too slow, esp. for use in washing machines, and they tend to form encrustations on the walls of the washing vessel at the air-liquid boundary).

Title: Sewn leather waterproofed work glove - is dipped in flexible plastic after sewing to seal seams and prevent peeling
Inventor: SEIZ FRIEDRICH
IPC: A41D19/015
Filed: 1975-07-03
Abstract: The sewn leather work glove has a plastic covering which extends over the stitching of the glove, which can thus be made fully waterproof. The coating retains its flexibility over a wide temperature range, and is hard-waring and non-inflammable, as well as waterproof. The coating normally covers the fingers and palm of the glove, but not the cuff (14). The back is coated if a fully waterproof glove is required, or otherwise left uncoated and so porous and permeable to air. Applying the plastic to the leather after the glove is made instead of before lessens the probability that the coating will peel off.

Title: Windscreen washer with fluid level warning - using level float and contact strips to operate warning when circuit broken
Inventor: NETH WOLFRAM DIPL ING
IPC: B60S1/50
Filed: 1975-09-12
Abstract: The fluid reservoir of the windscreen washer system has a float (21) moving along a vertical guide. Electric contact strips (20) on the guide are bridged by the float until a minimum level is reached. The circuit is broken and a warning circuit (22) operates the warning device (18). The device provides warning before the fluid is totally used and is especially useful for large fluid systems where headlamp washers are also fitted. A simple alternative uses a thermal switch, normally under the fluid level, heated by a coil in close proximity. As the coil and switch come out of the fluid the switch is heated and opens the circuit.

Title: Transformer magnetising and leakage current test circuit - uses compensated transformer against which transformer is tested by comparator circuit
Inventor: BRUECKEL WALDEMAR DIPL ING
IPC: G01R35/02
Filed: 1975-12-08
Abstract: The magnetising and leakage currents of a voltage transformer are tested by comparing an output voltage derived from a compensated transformer of the same kind, using a comparator network. A compensated transformer (N) consists of a primary winding (W1) secondary winding (W2) and tertiary winding (W3). The tertiary winding is driven by another transformer (T) connected in series with the primary winding (W1), via an amplifier (V) and compensating capacitance (C), to feed an operational amplifier (OP). The output of this is fed to a voltage divider (R2) and the output compared with the output of a similar divider connected to the secondary winding of the transformer under test. The required parameters can be read from the settling of the voltage dividers. Another more developed circuit for use with precision transformers, in which another transformer is incorporated in the comparator network, is also described.

Title: Sync. digital controller based on counter modules - has decade counters operating through preselected decoder stages to provide multiple subcycle mode
Inventor: DRIESCHNER HANS-PETER
IPC: G05B19/07
Filed: 1975-12-16
Abstract: A synchronous digital controller allows signals to be generated according to a pre-programmed time base. The unit is based upon decade counters coupled with decoder outputs transmitted over selector stages. Typically, two decade counters are coupled to separate 4 line to 10 line decoder stages. The decoder outputs are coupled to selectors. The number of selectors used will correspond to the number of sub-cycles involved. NAND gates respond to the selected combinations to set a flip-flop. A clock generator output is gated as a trigger pulse for the counters. In operation the counters are reset following one combination and re-cycle until the other combination appears. A gating circuit allows a separate delay between counter sub-cycles. The circuit may be used as a frequency divider.

Title: Rapid processing of pulp with reduced chemical consumption - by washing bleaching etc in a precompressed and subsequently expanded state
Inventor: TELL LARS ERIK KARL AXEL
IPC: D21C9/02
Filed: 1976-06-23
Abstract: Continuous treatment of fibrous material (cellulose or fibre pulp) comprises moving a liquid-impervious sieve element on an endless path along a web-forming zone, a cash zone, a treatment zone and a press zone in that order.; supplying the fibrous suspension of cellulose material to the web-forming zone and dewatering it on the sieve element to a fibre web; washing under overall compression the so-formed web adhering to the sieve element; supplying a liq or gaseous treatment medium to the fibre web in the treatment zone; and subjecting the web to compression in the compression zone. The fibre web is subjected to such a high compression in a compression zone situated between the wash-and treatment-zones that a transfer of treatment liquid from the treatment to the wash zone is largely prevented. The fibre web is released in the treatment zone, so that it can expand. A treatment medium is supplied to the expanded fibrous web in the treatment zone. Treating the pulp at concns. of 18-50% as compared with a =12% in normal practice reduces chemical consumption and process time.
