Title: Air-cooled gas turbine blade
Inventor: HALL KENNETH B
IPC: F01D5/18
Filed: 1990-02-08
Abstract: A turbine blade for a gas turbine engine has internal passages which are opened at their roots to supply pressure so that there is a constant flow of cooling air inside the blade in use. The blade has an airfoil surface and a number of internal passages inside the walls of the blade, some being formed adjacent the mid-chord section and extend from the root section to the tip section to define feed channels open at the blade root section. A number of radially spaced film cooling holes in the airfoil surface communicate with each feed channel to flow a film of cooling air adjacent the airfoil surface. A number of replenishment holes are radially spaced in the wall to flow air from the mid-chord section to the feed channel(s)  to replenish the cooling air in the feed channel(s) that is otherwise lost in supplying air to the film cooling holes. A device communicates cooling air from the root section via the feed channels to discharge from orifices in the airfoil surface at the tip section.

Title: Ring spinner spindle drive - has three phase synchronous motor with permanently energised rotor for control through switches
Inventor: WARBINEK KURT PROF DR ING
IPC: H02P25/03
Filed: 1990-03-30
Abstract: Drive system, esp. as an individual spindle drive  has a three-phase synchronous motor (1) with a permanently energised rotor. Controlled switches (S1,S2,S3) are operated by the drive control (3) so that, with the required high torque in the start-up and shut-down phase, all three phases are switched through from the frequency converter (2) to the three-phase coils (W1,W2,W3) in a star or delta configuration. To increase the working with the required low torque on normal operation, one of the three phase coils is disconnected from the corresp. phase after the required working speed has been achieved. Rotor is radially permanently energised to increase the holding action when the motor is at rest, and the holding action can be reinforced by applying DC to the three-phase coils. Frequency and amplitude of the phase voltage from the frequency converter (2) are varied for the three-phase system on start-up, shut-down, acceleration or braking of the motor, and they can be adjusted by the drive control (3). Short circuit is applied to the three-phase coils (W1,W2,W3) by the switches (S1,S2,S3) to stop the motor (1). USE/ADVANTAGE - For the workstation of a ring spinner. Mechanism gives a controlled drive for the spindle, with detection of drive faults, and prevents uncontrolled rotation when the spindle is at rest.

Patent DE-4012459-A1 (DE)
Inventor: SAILER KONRAD ING GRAD
IPC: E01F9/646
Filed: 1990-04-19
Abstract: The invention relates to a device for mounting and adjusting traffic installations and/or the lighting means thereof on traffic areas, for example in order to secure construction sites and hazard points in public traffic. Traffic installations of this type, in particular warning lights, are frequently carried by the police or other services in motor vehicles, usually cars. They have to be compact and, when used, are erected on the traffic area for securing purposes. In order to make the height of the light spot adjustable, when the traffic installation is erected on the traffic area, in such a manner that the emitted light signals or other information can be best seen by the road users, a moveable and adjustable connecting device is provided between the functional part (1), which supplies the information, and the supporting base part (3), which may contain the power supply device and the switch gear, this connecting device making it possible, after the erection of the base part (3) on the traffic area, to adjust the functional part (1) to a desired position. This connecting device is preferably designed as a telescopic rod (5) which carries the functional part (1) at the upper end as a provider of information. This telescopic rod (5) makes it possible to adjust the functional part (1) to a desired position, for example at approximately head height for a person sitting in a car. The information emitted by the functional part (1), for example optical signals, can thus be seen even at a relatively long distance in a queue of vehicles. <IMAGE>

IPC: C08L95/00
Filed: 1990-12-15
Abstract: The invention describes homogeneous, polymer-modified, bituminous compositions containing from 0.5 to 50% by weight of polymer constituents, where from 20 to 100% by weight of the polymer additive is polyalkyl (meth)acrylate, from 50 to 99.8% by weight of which is built up from C6- to C28-alkyl (meth)acrylates and from 0.2 to 30% by weight of which is built up from polymerisable, reactive monomers and from 0 to 49.8% of which is built up from further polymerisable compounds. The mutually reactive groups of the polyalkyl (meth)acrylate are made to undergo a covalently crosslinking reaction by thermal and/or catalytic activation. The crosslinking between the polyalkyl (meth)acrylate molecules containing reactive groups is furthermore also achieved by adding a reactive, organic, at least bifunctional crosslinking agent component which reacts with the reactive groups of the polyalkyl (meth)acrylate. Bitumens containing crosslinked polyalkyl (meth)acrylates are homogeneous and heat-stable, have high elastic recovery and good low-temperature flexibility.

Title: Measuring refractive index, stress profiles of transparent inhomogeneous bodies - by passing parallel light through body embedded in index-matched medium, aperture and polarisation beam divider to receiver
Inventor: MUELLER HANS-RAINER DR
IPC: G01M11/02
Filed: 1991-03-22
Abstract: Measuring the refractive indices and/or stress profiles of transparent inhomogenous bodies involves embedding the body (3) in an index-matched medium and illuminating at last part of its rod dia. perpendicular to the rod axis with parallel light. After passing through the rod and an imageing lens (4), the light is passed through a gap (5) via a polarisaton detecting polarisation beam divider (1) to a receiver (5). The receiver determines the centroid of the diffraction image produced by the gap. Polarisation direction influencing devices are added to cause quenching of one direction. The degree of the elements required is a measure of the stress profile in the rod. The light passing through the divider is used to determine the refractive index profile. USE/ADVANTAGE - Enables combination of refractive index and stress profiles and elimination of problems associated with beam deflection in object.

Title: Compensated magnetic field sensor - comprises magnetoresistive ferromagnetic thin layer strips arranged in one plane with insulated electrical conductor through which compensation current flows
Inventor: DETTMANN FRITZ DIPL PHYS DR
IPC: G01R33/09
Filed: 1991-06-28
Abstract: The magnetic field of the compensation current cancels out the magnetic field to be measured at the location of the thin layer strips.

The layer strip conductors are so connected to one another that the magnetic field in the magnetorestrictive thin layer strips is compensated. For each magnetorestrictive thin layer strip a layer strip conductor (10;9;11;8) lies in a plane (6). They are connected meander-fashion at their ends.

Title: Fixing device for two relatively movable components - has small solid bodies filling space between screw shaft and bore wall
Inventor: MIES KARL-HEINZ
IPC: F16B5/02
Filed: 1991-06-28
Abstract: One of the components has a bore larger than the shaft of the screw and the space between the shaft (9) and the wall of the bore (11) is filled up with e.g. metal balls (17) to provide a positive locking connection. After tightening the screw the maximum possible force is transferred which is determined solely by the sheer resistance of the screw. After loosening the screw however the two components can be adjusted relative to each other. During the adjustment movement the filling bodies move like a fluid around the screw shaft and fill up the cavities. If the screw is then tightened again the small filling bodies are pressed strongly against each other ensuring the positive locking connection. ADVANTAGE - Renewed adjustment of the components is possible after each time the screw has been loosened.
