Abstract: Weft, 29, Fig. 1, extending from a bobbin 51 through an open clamp 32, 38 and an eyelet 48 to the edge of the fabric is pulled down by a hook 28 so that a vertical stretch is. formed for engagement by a forked weft inserting needle 30. When the needle has taken a loop partway through the shed, the clamp 32, 38 closes and a cutter 21, 22 operating between the main warp 23 and auxiliary warp threads 24 cuts the weft attached to the fabric the loop of weft is then taken by a hooked needle 79 and straightened out into a single pick. Weft cutter, Fig. 3. The cutter consists of a blade 22 having a notch 74 formed with a cutting edge 75, and a blade 21 formed with a cutting edge 76 the blades are coupled together by a torsion spring which tends to keep them in the relative positions shown. The blade 21 is fixed on a shaft 18 which can be turned by a cam-operated rack 9 and pinion 15 to swing the blades down so that the notch 74 receives the weft as it is taken into the shed. At this stage, a tail 80 on the blade 22 encounters a stop 81, whereupon continued movement of the blade 21 ends the weft. The blades are swung clear of the reed at beat-up by a spring 60 acting on a lever 56 pressing the rack 9 against its cam 5.

Title: Phase locked oscillator for storage apparatus
IPC: G11B20/16
Filed: 1969-05-27
Abstract: In data storage apparatus, the frequency of a clock oscillator circuit controlling recording of digital data on a rotary data storage device (e.g. a magnetic disc pack) is controlled in accordance with the result of a comparison of the relative timings of clock pulses from the oscillator and timing pulses from a rotary timing signal generator (e.g. a toothed magnetic wheel) connected for rotation with the storage device. The clock pulses, after frequency division in a counter to give them the nominal frequency of the timing pulses obtained by shaping the output of a magnetic sensor sensing the teeth, are each compared with the respective timing pulses and according to which occurs first and the time between them, a duration-significant pulse is produced on one of two leads to charge or discharge a capacitor a corresponding amount. The capacitor voltage controls the oscillator frequency via D.C. and buffer amplifiers. A counter may be driven by the clock and timing pulses, and controlled by an index pulse obtained by sensing a ferromagnetic pin in the wheel.

Title: System for treating dilute slurries
IPC: B01D33/04
Filed: 1973-11-09
Abstract: A system for removing water from dilute slurries of the type discharged from waste water treatment plants, including feeding the dilute slurry into a reservoir and passing concentrically mounted endless screen and porous belts through the reservoir for absorbing water from the slurry. The water is squeezed from the belts and the thus thickened slurry is transported from the reservoir to a position for discharge onto the screen belt which moves in intimate contact with the porous belt. Such intimate contact facilitates further removal of water from the slurry by capillary action as the belts move linearly towards the end of the system. The belts then separate from each other. Water is squeezed from the porous belt and the screen belt with its slurry cake then runs through a pair of rollers for further slurry dewatering and compaction to a desired solids concentration. The thus dewatered slurry cake is then transferred to one of the rollers and subsequently removed from the system for ultimate disposal.

Patent ES-427362-A1 (ES)
Title: Digital speech detector
IPC: H04J3/17
Filed: 1974-06-18
Abstract: This relates to a digital speech detector applicable to a TASI communication system wherein the detector detects the presence or absence of speech in a plurality of digital code groups each of which indicate a quantized amplitude of a speech sample. The speech detector is divided into two portions. The first portion is an instantaneous detector that detects the quantized amplitude of each of the code groups in sequence and produces an up count signal when the detected quantized amplitude is greater than a first threshold value or less than a second threshold value less than the first threshold value and produces a down count signal when the detected quantized amplitude is between the first and second threshold values. The second portion includes an integrating counting circuit which integrates the up and down count signals and produces a resultant value of integration. The counting circuit produces a second output signal indicating speech activity in the code groups when the value of integration is above a third threshold value and produces a second output signal indicating an absence of speech activity in the code groups when the value of integration is below the third threshold value. The counting circuit has three different counting rates. The greatest counting rate occurs between a minimum count level and the third threshold value until the third threshold value is reached. An intermediate counting rate occurs between the third threshold value after it has been reached and a maximum count level until the maximum count level is reached. The smallest counting rate occurs between the maximum count level after it has been reached and the minimum count level until the minimum count level is reached again. The first output signal from the counting circuit is the signal that controls the assignment of those PCM code groups having speech activity to a particular one of the TASI channels transmitted from the transmitting portion of the TASI communication system.

Title: Removal of BOD and nitrogenous pollutants from wastewaters
IPC: C02F3/28
Filed: 1976-04-14
Abstract: A multistage treatment is disclosed for the removal of carbonaceous BOD and nitrogenous pollutants from wastewaters, wherein the influent wastewater undergoes successive nitrification-denitrification in the presence of recycled activated sludge containing a mixed culture biomass comprising heterotrophic and autotrophic organisms. The initial mixing of the wastewater with recycled sludge is effected in the presence of sufficient oxygen to maintain oxic conditions. The mixed liquor from the initial oxic treatment, without intermediate separation of solids, is passed to an anoxic stage wherein nitrites and nitrates (NOx<->, x = 2,3) formed by oxidation of ammonium compounds are reduced to nitrogen gas. Any number of oxic treating stages each followed by an anoxic stage may be employed. The final treating stage prior to solids separation from the mixed liquor may be either oxic or anoxic. The separated solids constitute the activated sludge recycled to at least the initial mixing stage. A short residence time, resulting in a high food to biomass ratio, is maintained in the initial oxic stage or the first subsection thereof, in order to avoid sludge bulking and to promote an active dense biomass.
