Title: Apparatus for making a fibrous web
Inventor: FEHRER ERNST
IPC: D01G15/04
Filed: 1985-07-02
Abstract: Apparatus for making a fibrous web comprises a plurality of carding drums (3, 4, 5, 6), which closely succeed each other in the direction of travel of the feed web and rotate in the same sense. An air-permeable collecting surface 7 is provided, on which the fibers of the feed web are deposited which fly from the carding drums (3, 4, 5, 6). Each carding drum (4, 5, 6) which succeeds another (3, 4, 5) in the direction of travel of the feed web constitutes a worker roller associated with the preceding carding drum. In order to increase the permissible speed of travel of the feed web, an additional worker roller (20) and a clearer roller (21) are associated with each carding drum (3, 4, 5, 6) on that side thereof which is remote from the collecting surface (7). <IMAGE>

Title: Cross-correlator
Inventor: DEKKER DAVID LINDSAY
IPC: G06F17/15
Filed: 1985-07-02
Abstract: To remove noise common to a pair of correlated real process derived signals, the positive time cross correlation function and the negative time cross correlation function are both determined, and the difference between the latter functions is taken. Apparatus is described. The functions may be evaluated by means of a physical single bit correlator even when input signals are resolved to be more than one bit resolution. A signal processing system is employed to update smoothed estimates of the difference at a rate equal to the sampling rate and to evaluate the median of the most likely time delay. <IMAGE>

Title: A clip for a tentering frame chain
Inventor: GRAFEN KARL
IPC: B05C13/00
Filed: 1987-07-06
Abstract: A two-armed clip 3 for a tenter frame chain is swingably mounted in. a clip body. Arm 8 of the clip 3 is influenced by a permanent magnet 12 to swing arm 6 to clamp a fabric web 1 against the underside of a part (2) of the clip body.

IPC: H01J61/90
Filed: 1987-11-20
Abstract: A flash lamp operating in the "pulse and simmer" mode has a cathode and an anode 18 mounted at opposite ends of a transparent envelope 10. The cathode, which may be water cooled, includes a mount 24 and a tip 26 joined to the mount by an undercut neck portion 28. Thus the tip 26 runs at an increased operational temperature due to the reduced thermal conductivity of the neck portion. The ratio of the diameter D of the tip 26 to its axial dimension C from the neck portion 28 may be in the range 0.3 to 0.5. In another embodiment (Fig. 4) the tip of the electrode is "mushroom shape" and has an ellipsoidal shape. <IMAGE>

IPC: B67D1/04
Filed: 1988-04-29
Abstract: A liquid dispensing device is described for dispensing a liquid e.g, wine, beer, other beverages, food products, or drugs, from a sealed container. The device comprises a body (41) having a manifold housing (10) for a gas cannister (15) for supplying an innocuous pressurised gas e.g. nitrogen.

Title: Repairing artificial and natural structures
Inventor: HAG I
IPC: E04G23/02
Filed: 1988-06-17
Abstract: In an inexpensive method of filling a cavity 3 opening in a cavity 2 of an artificial or natural structure 1 (or into a surface which is vertical or is inclined at any acute angle), a rigid shutter 4 is applied over the cavity and secured to the structure 2 and is sealed to the structure to form a fluid-tight enclosure. A coarse aggregate 6 is blown into the cavity 3 through a pipe 5 passing through the shutter 4 until the cavity is substantially filled with the aggregate, the weight of the aggregate at least in part being supported by the shutter. Air and any other fluid are evacuated from the cavity 3 and a cement grout is allowed to be drawn into the cavity through a second pipe 7 passing through the shutter 4 to fill the interstices between the aggregate. The cement grout is then permitted to set and bond to the surface bounding the cavity 3 and to the surfaces of the aggregate 6 and, after the cement grout has set, the shutter 4 is removed. The filled cavity 3 has a strength substantially matching that of the structure 1 itself. <IMAGE>

Title: Gas turbine engine reheat fuel control system and control valves therefor
Inventor: SMITH TREVOR STANLEY
IPC: F02C9/26
Filed: 1990-03-16
Abstract: A fuel control system for reheat burners of a gas turbine engine (10) has a plurality of metering units 12,13,14 including (flaps 2 to 5, not shown) metering valves (40, 62, 63) for respective burners, and throttle valves (54, 64, 65) in series with the respective metering valves (40, 62, 63). A pressure regulating valve (77) is provided for introducing fuel at a reference pressure into fuel manifolds (15, 16, 17) downstream of the respective throttle valves (54, 64, 65) when the metering and throttle valves are shut. The pressure regulating valve (77)(fig 6, not shown) also acts to relieve pressure in low pressure parts of the system when the latter is closed down and to prevent excessive temperature rise at the inlet of a fuel supply pump (26). The metering valves (40, 62, 63) include pressure return ports (49) which communicate with the metering valve outlets when those valves are shut.

Title: Collective ion accelerator propulsion engine
Inventor: TAPIO HAEYRINEN URPO
IPC: H05H3/02
Filed: 1990-03-30
Abstract: The engine of spacecrafts, here presented, is based on a diode principle where is a high tension electric field between the cathode and the anode. By using neutral gas blast (Fig. 4) and with field emission, it can be obtained a relativistic electron beam, which brings about an acceleration of collective ion crowd to a very high velocity. Because the output effect of the ion motor is related to the power of the beam (P=VI), which in this solution has the character of MW class or greater, a relatively powerful thrust is obtained by a relatively low propellant flow rate. This phenomenon is extremely useful in long space voyages. In the arrangement disclosed it would seem that an intense relativistic electron beam I generated from a cold cathode K is directed through an aperture in an anode/drift tube A where introduced propellant is ionised by the electron beam to form a plasma P. By ensuring that the injected electron beam current is in excess of the space charge limiting value the beam injected into the vacuum drift tube A forms a virtual cathode with a potential well which accelerates the ions from the plasma P, the virtual cathode moving with the ion bunch as indicated in Fig. 2 - hence generating the propulsive force. <IMAGE>

Title: A tile or sheeting
Inventor: TUSCH KLAUS NORBERT
IPC: B63B59/04
Filed: 1990-06-05
Abstract: There is shown a flexible rubber tile 1 which has a planar face 2 which in use is the exposed face, and an opposite face 3 in which there is a recess 4 defined by a boundary edge 5 of the face 3. Embedded in the tile adjacent surface 2 there is a copper or copper-containing mesh 2' arranged so that part at least of the copper is exposed to the surrounding medium such as sea water. The open mesh obviates the formation of algae or growth (marine fouling) and it may also act as a 'shielding' system using an electric current to run along the surface 2. Through hole 7, having non-return valve 8, enables recess 4 to be evacuated while adhesive, e.g. a two-part epoxy, bonds surface 3 to a substrate. Recess 4 may be replaced by a multiplicity of recesses connected by vacuum passages (Figs. 3 and 4). The same constructions may be applied to sheeting. <IMAGE>

Title: Communication line tester
Inventor: RANCATORE ANTONIO
IPC: G01R31/02
Filed: 1991-01-08
Abstract: A communication line tester comprises a DC voltage supply (+12V) and a threshold device (10) (Fig. 3). By using a tester at each end of a line (22, 24) a loop can be created by shorting (SW1 or SW2) the wires together. If the loop is complete, the DC voltage at the threshold device will exceed the threshold value and cause a buzzer (26) to sound and a light emitting diode (D1) to illuminate. By using known good connections the threshold may be set (R2) corresponding to a loop resistance above which the buzzer will not be actuated. The DC voltage supply (12V) and the threshold device (10) may be housed in a single housing (Fig. 1 not shown); and a microphone, amplifier and speaker circuit (12 Fig. 4 not shown) may also be incorporated. A tester at one end may operate merely as a signal transmitter and a tester at the other end may act as a receiver. <IMAGE>
