Title: Flow channel monitor for fibre flock - has embedded signal electrodes to prevent fibre flock material from snagging
Inventor: GASSER HERMANN
IPC: B65G53/66
Filed: 1976-09-27
Abstract: The passage of fibre flock material in an air stream, passing through a channel is monitored using insulated signal electrodes in the direction of air flow as a capacitative probe. The signal electrodes are situated so that, in the monitoring zone, they cover the cross-section of the flow in the channel. The electrodes are in a ring or spiral round the inner channel wall and, as they do not range into the air stream, are not fouled by the fibre flock material so that the flow pattern and resistance is not affected by the presence of the electrodes. The signals, therefore, represent the true flow condition and the circuitry is simplified.

Title: Weft control mechanism - has a catch and holder to support weft outside selvedge for cutting
Inventor: CARLSSON ERIK
IPC: D03D47/12
Filed: 1977-02-08
Abstract: The control system to regulate the weft insertion in a loom has a weft supply system at both sides of the loom, with the weft grip shuttles alternately forming a loop with the weft through the shed. A catch unit moves across the line of weft insertion for the wefts which are laid in place. A fixed holder and cutter are located in the path of the weft. The catch unit moves before the next pass of the gripper shuttle from the fabric edge to the weft supply along the outside path of the weft, so that the holder can keep the weft under tension until the cutter severs it. The system ensures that the selvedges are undamaged with a low technology mechanism, with a simple control action which is effective even when the loom operates at high speeds.

Title: Non-metallised stripes formed on metallised film for capacitors mfr. - by using an eroding disc wetted with mineral oil and kept clean by wiping blade, and applying HF AC discharge
Inventor: MORITZ PETER DIPL ING
IPC: H01G13/06
Filed: 1977-03-28
Abstract: Stripes free from metal are obtd. on a metallised plastics film by causing an eroding disc revolving between 2 diverting rollers to touch the metallised film in predetermined places; and applying a hf. AC voltage between eroding disc and the metal film in such a way that the metal film is not subjected to harmful shrinkage at the points of contact by capacitive coupling near at least 1 diverting roller, when an a.c. passes. The eroding sic is wetted with oil, upstream of the point of erosion, as viewed in the direction of rotation, and is cleaned, downstream of the point of erosion to be removed the oil and any residues resulting from the erosion. The metallised film is formed, at the erosion point, against the eroding disc, by means of a jet of compressed air. Used in mfr. of electric capacitors. Mechanical stresses exerted upon the film are minimal, thus reducing risk of deforming it by stretching.
Patent DE-2716871-A1 (DE)
Title: Collector groove for rolled steel bars - uses fixed and curved movable brackets to allow bars to roll without impact
Inventor: LANGER GUENTER
IPC: B21B39/00
Filed: 1977-04-16
Abstract: The collector for oblong objects, such as bars from a rolling mill is formed by several U-shaped brackets. A curved lever operated by a hydraulic cylinder is placed next to and in line, with each fixed collector bracket. When a rod rolls on the inclined supply track to the edge of the collector groove, it is held thereby the top end of the curved and hinged lever. As the lever moves away, a scissor action between the lever and the fixed bracket occurs. This allows the rod to slowly roll to the bottom of the collector groove without excessive noise being produced.

Title: N-channel storage IGFET with floating gate - has between drain and source N-doped auxiliary region in series with channel followed by further channel region
Inventor: ROESSLER BERNWARD DIPL ING
IPC: H01L21/28
Filed: 1977-09-30
Abstract: The floating storage gate is surrounded by an insulator. The gate charge change is carried out by electrons highly accelerated and heated in the transistor channel (K). The electron heating overcomes the energy threshold to the insulator conductivity band, owing to an electric field effective in the source (S)-drain (D) direction. Thus the electrons reach the storage gate and program the channel injection, thus charging the storage gate to a potential, negative relative to uncharged state, as in 2445137. Between the source and drain is incorporated an n-doped auxiliary region (HS) in series with the channel, behind which is provided a further chanel region (Ka) with a selector gate (Ga2), insulated from and affecting this channel region.

Title: Telephone exchange with peripherals - prevents data busying that has no prospect of being handled from blocking exchange equipment
Inventor: BOCEK KURT ING
IPC: H04Q3/48
Filed: 1977-10-27
Abstract: The telephone exchange, with peripherals and shared devices, is designed so that busyings that have no prospect of being handled do not block exchange equipment. A shared data line connects together control devices assigned to groups of peripherals. The data line is used to switch through several independent data lines and has a data coupler. Marking lines lead from the marking outputs of the peripherals. A selection device selects one request from several requests occurring simultaneously via the marking lines and switches a data line between a requesting control device and a requested control device.

Title: Sepg. naphthoquinone and phthalic acid - from naphthalene oxidn. mixt., by neutralising acid impurity, solvent extn. and crystallisation
Inventor: MATSUURA RYO
IPC: C07C46/04
Filed: 1978-01-10
Abstract: Naphtoquinone (I) and phthalic acid (II) are sepd. from the aq. slurry obtd. by treating a naphthalene catalytic, vapour-phase oxidn. prod. (A) with water. (A) contains (I) phthalic anhydride, maleic anhydride, SO3 and/or H2SO4. First the H2SO4 component and maleic acid are neutralised with base without neutralising (II), the mixt. is then heated to dissolve (II). (I) is then solvent-extracted from the (I) soln. while avoiding crsytallisation of (II). Pref. the extracted aq. phase is cooled to crystallise (II) and the aq. filtrate is recycled for reaction with (A). (I) is an intermediate for anthraquinone. By neutralising acid impurities decompsn. of (I) is prevented so yields and purity are improved. Since (II) is not neutralised only small amt. of base is needed.

Title: Blanks made by dry pressing of powders - has die connected to pneumatic pulse generator for complete filling of die
Inventor: FROHERZ BERND DIPL ING DR
IPC: B30B11/02
Filed: 1978-02-25
Abstract: The guides are used for making blanks profiled on their upper and lower sides. The dry pressing method can be used for materials previously compacted in wet state. The dimensional and form deviations which occur after pressing or sintering are limited to a min. e.g. a finish grinding process can be eliminated. When the die (5) is closed by the top ram (3) the material is loosened by a pneumatic pulse acting laterally on the material. This ensures that the die is properly filled with the material. The compressed air pulse is controlled in relation to the machine movements. The object is completed by further downwards movements of the ram (3).
