Title: Electric typewriter with error correction facility - has buffer store giving visible indication of typed line before release for printing
Inventor: GEISER GEORG DIPL ING DR ING
IPC: B41J3/46
Filed: 1976-05-13
Abstract: An electric typewriter is designed to facilitate the detection and correction of errors in a typed line. To achieve this the typing is undertaken in two phases. First a line of type is 'set' by key-operation and is tored in a buffer store provided with an alphanumeric readout. At this stage the line of type can be checked for errors. If no error is detected or after it has been corrected the line of type can released in the second 'printing' phase by operation of the space bar on the typewriter keyboard.
Patent DE-2626632-A1 (DE)
Title: Kieselguhr filter replenishing - by stream of water with nitrogen admixture under nitrogen atmosphere for oxygen exclusion
Inventor: NOBIS PETER
IPC: B01D37/02
Filed: 1976-06-14
Abstract: Kieselguhr filters, partic. those used for the filtration of beer prior to bottling, are packed with kieselguhr by a stream of water which has been freed from oxygen by the introduction of nitrogen in a tank. The nitrogen is also used to move it from the tank through the filter after the kieselguhr has been added to it. This saves having to recycle the first 20-50 hectolitre of beer every day which have too high an oxygen pickup from the ordinary water used for the kieselguhr deposition. The tank is filled with N2 when empty and a flushing out of any oxygen has been saved.
Patent DE-2634912-A1 (DE)
Title: Break monitor for covered wire winding machine - checks both the core wires and the covering thread
Inventor: RIPPLER HANS-PETER
IPC: D01H13/16
Filed: 1976-08-03
Abstract: During operation the core wires are brought together and covered with an insulating thread. A probe is provided to detect breaks in the covering thread by electrical contact. Novelty is that a voltage is applied to the core wires where they unite, and tested for where the wires are still separate; the resulting signals, and any coming from the existing electrical probe, are fed to a common circuit. The newly-added signals are pref. fed through a logic circuit and a delay element. By-pass switches may allow the monitor to operate also when the machine is used with less than the maximum number of core wires.

Title: Winding machine friction clutch - incorporates idling arrangement permitting driven part slow movement and prevents faster inertia running
Inventor: MAZZINI GIOVANNI
IPC: F16D21/08
Filed: 1977-03-11
Abstract: The device is for coupling a driven part to a drive, particularly for a drawing or winding machine and has a friction clutch which permits the torsion of the driven part against the drive against friction force. To prevent the further rotation of the driven part (1, 20) by reason of its inertia when the drive (3) stops, a free run or idling arrangement (1, 9, 5) is fitted between drive and driven parts. This allows the slow movement of the driven part (1, 20) relative to the drive (3, 5) but prevents the driven part (1, 20) running through its own inertia as opposed to the drive (3, 5). The driven part (20A) of the friction clutch (12, 14, 20A) is arranged between two counterposed surfaces (12, 14) of the drive (3).

Title: Decorative nonwoven mfr. - uses additional pattern yarns to be knitted into the fabric with the warps and wefts
Inventor: PREUSS EKKEHARD
IPC: D04B21/14
Filed: 1977-04-02
Abstract: In the mfr. of decorative non-wovens, a knitted structure is applied with warps and wefts which penetrate and are knitted in across the whole fabric width. Pattern yarns are gathered in front of the knitting needles, in the direction of the non-woven's travel, and are knitted into the fabric without regard to the distribution of the needles. The process gives a simple method of decorating nonwovens for curtains, and increases the range of designs and applications.

Title: Starting switch for motor driven hand tools - has three sets of contacts, one controlled by time delay element to by=pass starting current limiter
Inventor: BAAS JOHANNES J W
IPC: H02P1/02
Filed: 1977-12-16
Abstract: The starting switch for electric hand tools comprises three contact sets (2, 3, 4) which are mechanically coupled (5). Mains supply is connected to the first two sets of contacts. In parallel with the third switch is a current-limiting stage (7). In series with this is a delay mechanism such as a bi-metallic strip (8). This operates a latch (9) on the third contact. When the start button is operated, the first two contacts are closed, the third being held open by the latch. The starting current for the motor is limited by the current-limiter. Current also flows through the bi-metal element and after the delay time has elapsed, this then operates to release the latch on the third contact. The motor is then connected directly to the mains supply.

Title: Laundry folder - has a pivoted flap of structured length to reduce friction contact against the laundry pieces
Inventor: GEIGER FRIEDRICH
IPC: B65H45/04
Filed: 1978-04-11
Abstract: The unit to fold laundry items, along a line across their direction of travel on a conveyor, has a pivoted folding flap above the conveyor which, without a limit stop, gives a running plane of a length of 30-40% of the total length of small or medium laundry items, or 10-20% of the length of larger pieces. The running surface is either as a conveyor or as a low friction surface. The design reduces the length of the surfaces in contact with the laundry pieces, and ensures that overlaying folds are exact and correctly positioned.

Title: Pre-thickener for slurries before centrifugation - having hollow perforated cylinder or cone with spiral flight down which slurry runs to run off filtrate
Inventor: SCHILP REINHOLD DIPL ING
IPC: B01D29/90
Filed: 1978-04-19
Abstract: Liq. is sepd. out of a slurry using a sieve body esp. to prethicken a slurry before feeding it to a centrifuge or filter. The sieve consists of a vertical cylinder or one made from a perforated material. The cylinder has a spiral baffle inside it down which the slurry flows by gravity. As it flows down the spiral path it loses its liquid through the screen. In this way the slurry is thickened and concentrated. Used as a prethickener with centrifuges and filters. Reduces the loading of a centrifuge and thus its power consumption. Has a small constructional volume but high specific filtration rate per unit area of screen.
