Title: Dynamic fluidic logical element and a keyplate therefor
IPC: F15C5/00
Filed: 1973-08-22
Abstract: 1433239 Fluid logic elements KNORRBREMSE GmbH 22 Aug 1973 [22 Aug 1972] 39888/73 Heading G4P The element comprises a stack of plates of which one (main plate) is formed with channels and openings defining a main nozzle for forming a jet of fluid, a control nozzle for forming a control jet directed perpendicular to the main jet, and two channels to which the main jet can be directed by the control jet. Certain channels and openings in this plate communicate with a so-called key plate. The key plate has grooves on both sides of it, the grooves being interconnected by holes through the plate. The key plate is shown in top and bottom view and in section, in Figs. 3a-3c. Holes through the plate are shown at 41, 42, 47, 48, 53. Grooves of various widths are present as shown. The arrangement shown above centre line 46 is symmetrical about centre line 45, and that to the left of line 45 in Fig. 3a is symmetrical about line 46. As shown in the cross-section. Fig. 3c, grooves are interconnected by holes. The main plate may be as shown at the top of Fig. 4. Fluid presented to hole 65 is formed into a jet which is discharged via passage 75 or 76. The key plate is used in the orientation shown, with the shown sealing plates on each face. In operation fluid admitted at 65 passes to hole 41 as well as forming the main jet. From 41 the fluid flows via narrow passages 43, 49, acting as throttles, and passes out of hole 83<SP>11</SP> in the outer sealing plate if this hole is unblocked. The flow of fluid over hole 47 results in suction being applied, via the groove on the reverse side of the key plate, to opening 83 in the control duct in the main plate. This ensures that the main jet flows to passage 75. If hole 83 in the outer sealing plate is now blocked, fluid passes in to the control duct via hole 47 so that the main jet is now deflected to the right-hand passage 76. The fluid element is therefore monostable. A second control input flow may be applied at hole 78 to provide OR/NOR operation. If the main plate is provided with two control ducts, oppositely directed, and the sealing plates with two blockable holes (83, 85), one associated with each control duct, a bistable element is formed (Fig. 5, not shown). In this arrangement the jet can be switched from one outlet passage to the other by blocking the appropriate one of the holes. In another arrangement (Fig. 6, not shown), the orientation of the key plate is changed so that hole 42 is aligned with holes 65, the operation of the element being similar to that described with reference to Fig. 4.

Title: A broad band sound absorber and method for its manufacture
IPC: F16L55/02
Filed: 1965-09-20
Abstract: <PICT:1123803/C3/1> An absorber for sound transmitted through solid and liquid media and adapted to change the particle velocity of sound contacting the same includes a body 4 consisting of a dissipative incompletely cross-linked or incompletely cross-linked and plasticized polyurethane elastomer and compressible occlusions 5 of solid material.  The latter may be formed by closed cell, cellular particles or strips of foam rubber or resilient synthetic foam material while the body 4 may be secured by a layer of natural rubber adhesive 6 either direct to a sand blasted steel plate 1 of 12 mm. thickness or to a foil 7 which may be later secured to the plate 1 by a further adhesive layer 8.  After the body 4 has hardened, a layer 2 of liquid resistant material is applied and coated with paint which is toxic to vegetable or animal organisms.  The body 4 may be applied by direct spraying, moulding or painting or in a manner akin to that of paper hanging. To ensure incomplete cross linking, isocyanate hardener of less amount than that required for complete hardening is added to the polyurethane while to ensure freedom from gas bubbles liquid starting material of low viscosity, such as 100 to 300 cp., and a pot life of about 30 minutes are used.  The body 4 may have a weight of 10 g/cm.2, a degree of cross-linking of 10:3, a thickness of 5.0 mm. and occlusions in the form of strips 13 X 5 X 3 mm. and in one example may be formed of (a) a polyol component consisting of 22.3 parts by weight of a polyether formed of propylene oxide and trimethylol propane and containing 11.5% hydroxyl groups, 62.25 parts by weight castor oil and 11.45 parts by weight sodium-aluminium silicate; and (b) of an isocyanate component consisting of 30 parts by weight diphenylmethane-4-41-di-isocyanate.

Title: The Control of Dynamoelectric Machines

Abstract: 1,194,587. Control of A.C. motors. SIEMENS A.G. 31 Aug., 1967 [3 Sept., 1966], No. 39972/67. Heading H2J. [Also in Division G3] The rotor of a three phase machine 1 is supplied with current from a source 5 via rectifiers controlled so that the resulting field of the rotor is always in synchronism with, and at an adjustable phase angle to, the stator field, whatever the actual speed of the rotor. As shown, the slip angle of the rotor is measured at 9 as a voltage which is converted to the frequency of pulses at 10; pulses representative of the desired angle are subtracted at 12 and the difference # applied to devices 13 ... 16 which produce three phase reference currents IR, IS, IT at the difference frequency #and of magnitude set at Ie, which are compared at 2 with the actual rotor currents measured at 4 and the difference used to control the triggering circuits 3 of the controlled rectifiers (thyristors) in an unspecified manner. In an alternative embodiment (Fig. 3, not shown) the control signals are produced by two devices like 16 one of which lags 90 degrees behind the other and their magnitude control signals represent desired values for active and reactive components of the stator current. The frequency in this case is derived by comparison of actual rotor speed with synchronous speed, and is modified to produce the desired phase angle by a signal whose frequency represents the difference between the desired active and reactive currents and their actual values measured by transformers in the stator circuit. In this embodiment the machine may be a generator. In Fig. 6 (not shown), this system is further extended in that the desired value for active current is derived from a signal representing average power required which is overridden if the actual speed departs from a desired speed by more than a fixed amount e.g. 3%. This last embodiment is for a motor driving a generator for a proton accelerator, the motor acting as a buffer against the intermittent shock loads.

Abstract: 947,239. Pneumatic conveyers; reciprocating conveyers. E. SALMONA. Nov. 8, 1961 [Dec. 10, 1960], No. 40054/61. Heading B8A. In a pneumatic conveyer system for transferring articles such as knitted stockings 25, Figs. la, 1b, 1c from a plurality of machines 1 to multiple sorting receptacles 37, the valves 5 of collecting funnels 3 at each machine 1 are opened sequentially in a time cycle which is less than the minimum interval between deliveries from a machine 1 so that only a single article or stocking is received at each operation. The articles pass to a chamber 12 having a discharge flap 13 which is automatically opened by an electric motor 23 under the control of a photo-electric detector 14 operable when the article reaches the required position. The detector 14 further controls a valve 16 to shut off the suction from the conveyer fan 17 and to operate a blower 20 coupled by nozzles 18 for blowing the articles on to an inspection table 26. A further photo-electric detector 10 may be provided in the conveyer line 7 and operates valves 8, 9 to open the line to atmosphere and throttle the flow so that the speed of the article is reduced before entering the discharge chamber 12. After removal by hand from the table 26 and inspection on a tapered pipe 27 the stockings are drawn into a second conveyer line 7<SP>1</SP> having a similar chamber 12<SP>1</SP> and discharge flap 13<SP>1</SP> from which the stockings fall on to a tiltable shelf 29, which is movable by a carriage 30 to a selected receptacle 37. Stops 34 operated in a timed sequence operate to tilt the shelf 29 so that the stockings 25 fall into the selected receptacle 37 according to size. The device controlling the sequential opening of the valves 5 and the stops 34 comprises multiple cams (Figs. 2a, 2b, not shown) driven by a common shaft, the cams controlling the stops 34 being set to operate after a delay sufficient for the time taken at the inspection stage. The cams may also operate signal lamps 39, 42 and counting devices 40 in the respective circuits for each machine 1. Push buttons 42 may also be incorporated on the table 26 and are operated to override the cam operated switches if a particular article requires rerouting after inspection.
