Title: Improvements in or relating to Methods and Apparatus for Removing Moisture from Organic Materials, Foodstuffs and other Moisture-Containing Substances.
IPC: B29C71/00
Filed: 1967-11-15
Abstract: A method of drying finely-divided material (e.g. food or organic materials) comprises passing the material through a treatment chamber, introducing into the chamber a dehydrating gaseous fluid so that it passes in the same direction as the material, collecting the dried material and recirculating the spent dehydrating fluid in a closed circuit to the treatment chamber. The spent fluid is successively separated from any solid particles entrained thereby, initially cooled in a heat exchange, further cooled to remove by condensation vapours contained in the fluid, initially heated by heat derived from the initial cooling step, further heated to the desired temperature and reintroduced into the treatment chamber. The material may be passed through more than one chamber, the chambers being provided with a common fluid recirculating system or the chambers each being provided with a fluid recirculating system. In the embodiment shown, material from pipe 2 and dehydrating fluid from duct 7 are passed into chamber 1. The dehydrated material is discharged into tank 5 or is recirculated to top of chamber 1. The dehydrating fluid from chamber 1 is passed to cyclones 8, 10 in which any solid material is removed from the fluid. The fluid is then cooled in heat exchanger 11 and treated in dehumidifier 12 in which liquids absorbed from the material in chamber 1 are condensed from the fluid. The condensed liquids are separated in separator 13, the water being discharged through outlet 14 and the other liquids being returned to the treated material. The dehumidified fluid is passed through fog separator 121 and pump 15 is then returned to chamber 1 via heat exchanger 11 in which it is heated by the dehydrating fluid passing to the dehumidifier 12, and heat exchanger 16.

Title: Glass sheet supporting and conveying apparatus with means to change the contour of the conveyor
IPC: C03B35/18
Filed: 1968-03-22
Abstract: Apparatus 10 for bending glass sheets 26 includes conveyer rolls 13 which are adjustable, to conform to the plane or curved contour of a sheet, by varying a tensile force applied to the rolls. Each roll comprises tubular stub shafts 30, 31 and a centre section consisting of a coil spring 32 that is secured at its ends to the stub shafts. The shafts are driven by chain and sprockets 36, 37. Through the centre of the roll passes a cable 40 secured at one end to the stub shaft 31, the other cable end being connected to a double-acting cylinder 41 controlling tension applied to the cable. For maintaining the cable concentric with the coil spring 32, cylindrical members 42 are secured to the cable. The surface of the roll is of woven asbestos or fibre glass cloth 38. The apparatus 10 also includes a substantially stationary upper mould member 11 and a movable lower mould member 12 of ring-type outline comprising transverse segments 17 and longitudinal segments 18. An air-operated ram 24, 25 raises and lowers the mould 12. When a heat-softened flat glass sheet is fed from the left in Fig. 1, the roll cables 40 will be under tension. The sheet, in passing on to the rolls 13 causes a photo-electric device 81, 82 to initiate a sequence in which the mould 12 is raised for a timed interval, the tension on the rolls 13 is relaxed to adjust the rolls to receive the now bent sheet and two stops 28 are lowered to permit the sheet to be discharged. The stops are then raised again and the rolls retensioned. An electrical circuit for controlling the pressure system of the apparatus is described with reference to Fig. 6 (not shown).

Title: Apparatus and method for de-registering tow
IPC: B65H51/005
Filed: 1968-10-24
Abstract: Apparatus for de-registering crimped tow comprises means 18 for longitudinally advancing a multifilament tow sheet 10, means 14 for frictionally gripping the tow sheet at spaced intervals transversely thereof in advance of the advancing means 18, and means 13 immediately in advance of the gripping means for reciprocating the tow sheet transversely as it moves to the friction means 14. The friction means 14 comprises a pair of rollers at least one of which is provided with circumferential grooves and ridges, the other preferably having a covering of resilient material e.g. hard rubber. The reciprocating means comprises a circumferentially grooved and ridged roller which is reciprocated axially by means of a lever connected to a dowble-acting pneumatic piston and cylinder. The reversal of the reciprocation may be synchronised to the rotation of the rollers in the friction means 14 by means of a cam secured to one of the said rollers. The filaments of the crimped tow are partially de-registered by the reciprocating means 13 and further de-registered by the friction means 14. In a further embodiment, two tow sheets are passed through their respective reciprocating, friction and advancing means, and then brought together for further processing e.g. cutting into staple length fibres.

Patent ES-431110-A1 (ES)
Title: Doppler sonar utilizing period measurement with thresholded receivers
IPC: G01S7/527
Filed: 1974-10-17
Abstract: Speed measurement error due to additive noise in the receivers of period-measuring doppler sonar apparatus is reduced by performing the period measurement process when and only when the signal is sufficiently strong. When the envelope of the received signal-plus-noise exceeds a preset threshold, a comparator output enables the initiation or the continuation of a doppler gate until N received periods have been counted. Typical logic, gating, counting and display circuitry is described which transforms this gate duration into an accurate indication of speed. Higher threshold levels can be established for increased accuracy at the expense of increased measurement time.

Title: Dual-circuit brake system
IPC: B60T13/12
Filed: 1975-11-07
Abstract: The brake system includes a tandem master cylinder and a control valve for introducing pressure supplied from a power source. The main feature of the present invention is that the pressure from the power source is first introduced into annular chambers behind the sleeve seals of both the tandem master-cylinder pistons. This makes it possible for the pistons to travel only a small distance if power from the power source is available. Thus, the pistons can be dimensioned in accordance with the force the driver is able to exert with his foot in the event of failure of the power source.

Title: Circular knitting machine
IPC: D04B15/66
Filed: 1976-06-11
Abstract: An arrangement for producing synchronization pulses for pattern control of the knitting needles of a circular knitting machine. The arrangement includes a plurality of control units mounted on, for example, the cam housing, which units coact with the butts of the knitting needles mounted on the needle cylinder.

Patent ES-451157-A1 (ES)
Title: Inversion brake valve and system therefor
IPC: B60T15/18
Filed: 1976-09-01
Abstract: A pneumatic brake system employing dual-diaphragm, spring-actuated, air-released brake actuators is provided with an inversion valve which, in the event of a brake system failure, prevents the brakes from being automatically applied while permitting controlled brake application by releasing compressed air from each actuator's spring chamber in an inverse ratio to that normally supplied from the system by the operator applied brake valve thus permitting a controlled spring brake application. The valve employs first and second pressure responsive pistons with associated valve seats to maintain the actuator springs compressed with air at supply pressure when the vehicle is normally operated. The air at supply pressure in each actuator's spring chamber is automatically ported to a lower pressure through the valve when a system failure occurs and prior to brake application to insure fast response time of the spring actuated brake.
