Abstract: 1,197,321. Clasifying dry cleaning solvent. K. S. ARVANITAKIS and G. GOUTOS. 23 Aug., 1967 [29 Sept., 1966], No. 38815/67. Heading B1D. Dry cleaning solvent is conveyed from the sump pump of a conventional dry cleaning machine (not shown) via pipe 20, Fig. 4, to pump 16 and hence to a primary filter 66, which filters a major fraction of the solvent which is re-delivered to the machine via conduit 110, 118; the minor fractions flows down to secondary filter 94 and is returned to the machine via conduits 104, 110, 118. Adsorbent powder may be added to the solvent. As described, incoming solvent is splashed against dome 34 by pipe 42 to suppress turbulence. Filter 66 also illustrated in Fig. 2, (not shown) comprises a plurality of filter discs 68 rotatably mounted on shaft (72) and outflow tube (70). When the discs 68 rotate they are cleaned by brushes (86). Purging the filter. While clothes are being unloaded from the machine the filter 66 is cleaned, by rotating discs 68. Foreign particles thus settle to the bottom of the tank, and pump 16 is then energised, valve 116 being closed, to circulate the solvent through the tank. Valve 116 is opened and solvent drawn from the machine, powdered activated carbon being added by a conventional injector (14), Fig. 1 (not shown): the powder coats the discs 68 of filter 66, which is thereby regenerated. Removing foreign matter from the apparatus. This is done at 4-8 week intervals. The machine is shut down and live steam is introduced through pipe 134 to force solvent through filter 94, outlet 138, pipe 140 to a condenser 146 and to a separator 150. Separator 150, see Fig. 6 (not shown) allows the solvent and liquified steam to separate by gravity. The inside of tank 18 is then cleaned manually. Fig. 8 (not shown) illustrates a carbon filter provided with a cooling coil (198) which is optionally connected to output pipe 118.

Abstract: 1350075 Finishing fabrics M ACKERMAN 27 July 1971 [20 Aug 1970 17 June 1971] 40131/70 and 28454/71 Heading D1S A woven woollen fabric is stabilized by generating static electricity within the fibres of the fabric to effect agitation and reorientation of the fibres thereby relaxing the fabric. In one embodiment, Fig. 1, a fabric 2 is unwound from a roll and passes over a slotted tube 3 supplying hot compressed air, a curved frame 4 covered with steel mesh holding the fabric against the slot. The pressure and temperature of the air and the fabric feed rate are accurately controlled so that static electricity is generated within the fibres of the fabric. These electrical charges may be reinforced by drawing the fabric over a series of ebonite rods 5. A row of jets 6 cause steam to impinge on the fabric and the deposited moisture is drawn through the fabric through a slot in a tube 7 connected to a suction pump. This moisture treatment removes all electrical charges from the fabric. Heated takeup rolls 8 are provided. In a second embodiment, Fig. 2, the fabric 2 is intermittently fed over a steel mesh platform 9 resting on an open-top chamber 10 enclosing a cluster of jets 11. coupled to a steam supply and a pipe 12 coupled to heated compressed air source. A cowl 13 has an outlet pipe 14 connected to a suction pump and has its base covered with steel mesh to prevent lift of the fabric. In use the fabric is fed so that an untreated section thereof completely covers the platform 9.

Title: Apparatus and method for leveling metal strip
IPC: B21D43/28
Filed: 1972-09-01
Abstract: 1348083 Tension levelling strip; feeding strip; shearing PRODUCTION MACHINERY CORP 1 Sept 1972 [17 Dec 1971] 40683/72 Headings B3A B3E and B3W A method of tension levelling metal strip comprises feeding strip A in a longitudinal direction 22, gripping the strip at longitudinally spaced locations with grippers G, H, moving the grippers apart to stretch the strip, transferring the stretched strip from the grippers while simultaneously transferring a fresh strip length to the grippers, and trimming opposite edges (136), Fig. 3 (not shown), of the stretched strip in the region of the spaced locations to a width not greater than the width of the stretched strip. Rolls 36, 38 continuously feed strip A to loop forming station F while rolls 80, 82 continuously pull the strip from loop forming station K. Pinch rolls 60, 62 are intermittently operated to feed an unstretched strip length to gripping jaws G, H where an hydraulic cylinder J, when activated, moves jaws H away from jaws G in direction 22. At least one of each of the pairs of feeding, pulling and transferring rolls is continuously driven so that the strip feed may be stopped by removal of the driven roll from the strip. A parting shear L is positioned adjacent rolls 80, 82 and precedes longitudinal trimming means M. An additional loop forming station N is provided between the trimming means and further feeding means O. The strip can be fed through shear P for shearing short lengths of strip damaged by the gripping jaws, or alternatively, roll 104 can be lowered and the strip coiled at station Q on to coil 120 with subsequent shearing at another location. Instead of forming coil 120 guide roll 108 may be lowered and a driven conveyer R may be lowered to receive sheared strip lengths fed by a vacuum lifting device S which also sorts out reject strip material. Feeding of strip A in direction 22 reduces the size of loop 34 and increases loop 58. When jaws G, H grip the strip roll 60 is raised, or the motor drive is stopped, to cease movement in loop forming stations F, K. Rolls 36, 38 continue to feed strip to increase loop 34. During the stretching, rolls 80, 82 continue to pull strip from station K to reduce the size of loop 58. After the stretching, jaws G, H are released from the strip and rolls 60, 62 feed the strip to increase the size of loop 58. Loop forming station N provides a slack loop 92 so that rolls 102, 104 may intermittently move stretched portions of metal strip past shear P to removed damaged areas (T), (U) by shearing along lines (138), Fig. 4 (not shown). Vertical loops provided by vertically movable loop rolls may be used instead of the stations F, K, N. Photocells 160 may be provided for sensing imperfections or perforations in locations (T), (U) and for accurately stopping the strip so that shear P will remove only the damaged strip lengths. The trimming means may comprise transversely spaced pairs of upper and lower shearing discs (140), (142), Fig. 2 (not shown).

Title: Aircraft flight path guidance
IPC: G05D1/06
Filed: 1974-09-19
Abstract: 1477656 Automatic control of aircraft BODENSEEWERK GERATETECHNIK GmbH 19 Sept 1974 [27 Sept 1973] 40902/74 Headings G3N and G3R In a system in which an aircraft is controlled by a first closed loop in which at least an elevator is adjusted in response to an altitude error signal and a second closed loop in which at least engine thrust is adjusted in response to an error in aerodynamic condition of flow, e.g. angle of attack or lift coefficent, the engine thrust is controlled in addition by an open loop signal derived from a vertical flight path generator which also provides the desired value for the altitude loop. The flight path generator 10, also Fig. 4 (not shown) produces a desired height signal h soil and, preferably, a glide angle signal γ soil as a function of range from a landing point measured by a glide path radio receiver. It is shown mathematically that the engine thrust S should be adjusted proportionally to the glide path angle so signal γ soll is combined with the closed loop signals for the engine at 72. Alternatively, the open loop thrust signal may be made proportional to aircraft weight times the quotient of the commanded rate of descent and the commanded or actual air speed, or the air speed may be assumed to be constant and represented in the signal generator by a fixed resistor. The figure shows how the elevator 68 and engine 70 are controlled by a combination of signals; in the figure the following are measuring devices:- angle of attack 32, rate gyro 42, longitudinal and vertical accelerometer 44, barometric altimeter 16, glide path receiver 18, radio altimeter 20. An OR logic 14 selects the appropriate one of the latter three devices for the actual value of height for comparison at 12 with the desired value from 10 to form altitude error #h. A second function generator 30 produces either the desired angle of attack α soll or lift coefficient as a function of range, or alternatively it produces two different but fixed signal levels selected at prescribed heights; in all cases this generator produces the desired "aerodynamic condition of flow" signal from which the error in this quantity is produced at comparator 34. The devices 36, 46, 54, 56 and 22 process the measured values by differentiation and integration to produce the following outputs:- proportional and integral 38, 40 of the "aerodynamic condition" error, angular acceleration in pitch 48, pitch rate 50, pitch angle 52, a signal corresponding to the rate of elevator movement, by double differentiation, 53, longitudinal speed 58 and acceleration 60, vertical speed from 56 and from 22 at 24, and proportional and integral values 26, 28 of the altitude error. These outputs are combined in a matrix unit 66 as shown to control the elevators and engine.
