IPC: D04H1/56
Filed: 1973-06-28
Abstract: High quality fleece mata comprising fusion/blown polymer fibres, particularly polypropylene fibres, are produced by the high-velocity extrusion of fibre-forming thermoplastic resin in a molten state, through openings in a heated nozzle, into a stream of hot inert gas which draws the molten resin into a cluster of fibres which are collected in a receptacle along the path of the fibre stream to form a fleece mat.

Title: Small concrete mouldings produced to accurate dimensional tolerances - are esp. useful as spacers for shuttering work
IPC: B28B3/02
Filed: 1976-12-24
Abstract: Concrete mouldings of definite, accurately adjustable height are produced from fresh concrete with great accuracy of their circumferential surfaces. The moulding is formed with vertically standing outside surfaces by filling a suitable mould having a volume VF with undensified fresh concrete. This filling is briefly pressed down to a predensified volume VV. The volume VF-VV freed by the compression is filled again with fresh concrete and is pressed down or vibrated and finally densified to the desired end volume VE of the moulding which is then removed from the mould. When v is the percentage of the starting volume to which the filling of fresh concrete is predensified, e is the percentage of the starting volume to which the refilled fresh concrete is finally densified, x is the percentage of the starting volume to which the predensified concrete is compressed finally, a moulding is produced with a final volume VE. This volume can be calculated from the predensification v using the equation - VE/VF = e-e v + x. v in which x is a function of v, which is chosen in such a way that for v = 0,6 the value of x =1 and for v approaching the value 1, the value of x approaches e, and values for v 0.6-1.0 and for e 0.6 - 0.75 must be selected. x linear dependent upon v is determined from the equation x = 2.5 (v.e-v+1)-1.5e. Provides a method and equipment by which small mouldings can be produced quickly to highly accurate definite and adjustable heights and surface plane dimensions. When used with shutterings for floors and walls, considerable economies in the quantities of concrete poured can be made, whilst conical plugs for filling in where steel shutters have been used, fit accurately.

Title: Rail wheel slippage counteraction system - compares signal of frequency representing angular velocity with one generated in vehicle
IPC: B61C15/12
Filed: 1977-08-01
Abstract: The system counteracts slippage between a rail vehicle wheel and the rail, generating an electrical signal measuring the angular velocity of the wheel by means of an a.c. component whose frequency is proportional to this velocity. This component is compared with an a.c. signal generated in the vehicle, deriving a signal proportional to the phase difference between these two a.c. signals, and which reverses polarity on phase opposition. This signal is fed to an integrating unit, whose output signal is delivered to an oscillator, generating an a.c. signal proportional to that of the input signal. This signal from the oscillator constitutes the one generated in the vehicle. The integrator unit input signal is used as a measurement of the wheel angular velocity.

Title: Vacuum impregnating method for timber protection - includes sealing stack inside sheet and housing in tank before pumping liquid inside sheet
IPC: B27K3/08
Filed: 1978-01-10
Abstract: A method for impregnating a stack of timber with a liquid to protect it against fire or termites, bacteria fungus etc., includes enclosing the stack inside a flexible sheet inside a fixed vessel, then sealing the joint between the sheet and the vessle. The air inside the sheet is then removed by suction, and the impregnating fluid pumped inside the sheet. The vessel can be filled with water to maintain pressure on the contents of the fluid filled sheet, and this ensures good penetration of the impregnating fluid into the wood stack. Packers can be inserted between the members of the stack to assist penetration. The flexible sheet can be attached by suitable securing members for the operation giving adequate sealing.

Title: Brushless electromotor for servo system - has low rotating mass with disc rotor and multipole stator for improved speed control
IPC: H02K29/00
Filed: 1990-09-06
Abstract: A shaded pole motor with a split stator and disc rotor has a large number of between 20 and 80 poles (2) in each stator half. A basket weave type winding (1) is incorporated in each half stator. During assembly the half stators are placed such that the pole gap in one half coincides with the centre of the pole in the other half. The AC supply to one stator half is displaced by 90 deg. Speed variation is achieved via frequency control or by changing the phase angle difference between the stator supplies. The rotor disc is made of non-ferrous material and thus transparent to the magnetic flux circuits which are formed and closed between the stator poles. Rotation occurs due to the generation of Foucault current in the disc reacting against the flux lines.
