Abstract: 1308999 Automatic needle loom WILLIAM BYWATER Ltd 3 Dec 1971 [3 Sept 1970] 42181/70 Heading D1R An automatically controlled needleloom comprises a bed across which material is fed, a needle board which is reciprocated relative to the bed, a control unit which adjusts the bed by small increments towards the board to allow for needle wear and an activating means which is pre-set or automatically operated to activate said control means at predetermined intervals and for a predetermined duration. The control means may include means for varying the increments of adjustment of the bed.  In the example the activating means is a counter A which records the number of reciprocations. When a predetermined number has been counted a motorised potentiometer C is rotated to a position set by an increment selector B, producing a voltage difference between potentiometer C and a second potentiometer D mounted on the bed. The voltage is amplified and used to drive an incremental motor which raises the bed until the voltage difference between the two potentiometers is zero. An alarm sounds when no further incremental displacements of the bed are possible. Alternatively the activating means may comprise a metering device which records the passage of material through the loom, a time clock or a tape reader into which is fed a tape detailing the frequencies and increments of bed movement.

Title: Density measurements
IPC: G06J1/00
Filed: 1969-07-17
Abstract: 1315120 Measuring density SOLAKTRON ELECTRONIC GROUP Ltd 2 July 1970 [17 July 1969] 36159/69 Heading G4H In a density transducer of the type operating on the natural resonance frequency principle, in which a quadratic relationship exists between density of the medium and the time difference between periods of a liquid under test and a standard liquid, a computing unit is used to derive an expression for the density, and mass or volume flow rates, and total mass. The output from a density meter 10 passes via a divide by n circuit 12 to a timing unit 14. This unit produces reset pulses on line 16, which are used to control statisizer 17 and to reset counter C3 and flip-flop 21. Counter C2 has an output on line 20 at a time corresponding to the period of a standard liquid. This results in flip-flop 21 being set for the difference between the standard liquid and the liquid under test. Gate 23 is therefore opened for this time difference and controls the outputs from G1 and G2. Counter Cl together with its associated logic G1 generates a train of clock pulses representating f 0 dt and counter C2 and its associated logic G2 provide a train of pulses representing (f<SP>2</SP> A t)dt. These two outputs, gated by 23, are supplied to counter 23 which thus indicates density The value of density thus obtained is stored in statisizer 17. A binary input of a density may be obtained at 28, and an analogue representation of a density may be obtained via logic Gl<SP>1</SP> and frequency to analogue converter 30. A flow meter 33 in conjunction with counter C4 and logic G4 produces a signal representative of the mass or volume flow rate, which may be put in analogue form via converter 35, or accumulated on a counter C5 to give the total mass. The flow meter may be of the turbine type, or of the differential pressure type. If a differential pressure type flow meter is used an analogue calculator circuit is employed.

As described, the chamber 12 has lifters 14 and either effects autogenous grinding or includes a charge of steel balls. Where autogenous grinding is employed, the large grinding material (e.g. stones) is removed via the tube 13 and rotating screen 21 and a pipe 34 to a conveyor 35 which feeds it to a hammer mill 36 prior to its being recirculated. This recirculation path is not required where primary ball milling is used, Fig. 5 (not shown). In operation, material supplied at 1 is fed by a conveyor 2 to the inlet trunnion 6 of the mill together with hot drying and feeding air from either a furnace 47 or from a rotary cement kiln via a pipe 51. After grinding in compartment 10, fine material passes through the partition 8 for secondary ball milling in compartment 11. The fine material leaves this compartment via the partition 9 and is lifted by scoops 16 in the chamber 12 into the outlet trunnion 7. The finest material by passes the second compartment and is carried by the air stream directly to the outlet via the tube 13. Coarser material is forced through the pipe 13 and is separated in the screen 21. The finest product passes via a cyclone 24 and electrostatic separator 28 and worm-conveyor 30 to a product outlet 45 and the other product after screening at 21 is treated in a cyclone 42. The coarser material is recirculated from the cyclone 42 via pipe 46.

A copper or stainless steel pipe 1, Fig. 2, is surrounded by a mild steel or stainless steel casing 2, the end rings being of double cup form, of stainless steel, to allow for longitudinal thermal contraction of the pipe within the casing. The insulant 3 is of preformed mineral wool, rock wool, glass fibres and may be in powder form, preformed slabs or wrapping, or consist of a porous mass formed in situ from an aqueous slurry or from a foamed plastics, e.g. polyurethane. The inlet 6 and outlet 7, provided at each end of the casing 2, are for swaging the insulant with dry incondensible gas. Two such pipe sections are coupled by a sleeve 8 joining pipes 1; insulant 9 such as above surrounds the sleeve 8 and aluminium foil cladding 10 is applied over adjacent casings 2 and the insulant 9. Finally P.V.C. sealing tape 11 seals the cladding 10 to the casings 2 and adjacent vents 6, 7 are connected.
