Title: Linear motor
Inventor: KELLY HUGH-PETER GRANVILLE
IPC: H02K41/03
Filed: 1981-05-13
Granted: 1986-05-07
Abstract: A linear motor comprises an armature and a stator each adapted to provide a sequence of North and South poles along the length of the motor. The pole pitch of the stator magnets is different from that of the armature coils such that with appropriate energization of the coils this difference in pole pitch and stator can result in a net thrust of the armature relative to the stator in a desired direction at any location within a range of relative longitudinal positions of the armature and stator. The motor may be subject to closed loop velocity-and/or positional control and means are disclosed to achieve this. Several variations in pole configurations and means of controlling the coil energization are disclosed.

Patent DE-3276688-D1 (DE)
Title: Method of adhering abrasive material to an abrasive body
Inventor: BRAASCH GERD
IPC: B24D9/04
Filed: 1982-11-19
Granted: 1987-08-13
Abstract: The invention relates to a method for bonding grinding material, in particular, endless grinding belts or grinding belt segments onto a grinding element, preferably a grinding disk, or the like. Used endless grinding belts can be removed from the grinding elements only under great difficulties. However, such operations must be performed at regular intervals, as soon as the service life of the endless grinding belt has been exceeded. In particular, the removal of adhesive residues from the grinding element is a tedious task and the use of aggressive solvents is disadvantageous for the adhesive. In order to eliminate these disadvantages, the invention provides that a separating layer which is made of an unstable material with respect to solvents, is applied on at least one of the two engaging faces of an endless grinding belt and the grinding element before applying the adhesive layer. Preferably, the separating layer is mounted on the engagement face of the grinding element. As a material for the separating layer, an adhering agent, for example, a plastic resin is particularly suitable. The endless grinding belt can be bonded onto this adhering agent. Since the material used for the separating layer is easily dissolvable with a mild solvent, a used endless grinding belt can be easily removed from the grinding element, without any remaining adhesive residues.

Title: Improvements in display signs
Inventor: GRANSDEN RONALD GEORGE
IPC: G09F13/06
Filed: 1983-09-22
Granted: 1987-06-11
Abstract: A display sign of novel appearance is described in which the display plates (20) are formed of a profiled and rolled sheet material. In addition to the enhancement in appearance, the construction employs plates (20) having significant structural rigidity with the result that the framework (14, 16) supporting the plates (20) and the internal lights (18) need not itself be substantial. Cut-outs (32) are formed in the sheets (20) and mouldings of acrylic material (not shown) are mounted in these cut-outs (32), the mouldings being in a contrasting colour. If the edges of the mouldings remain translucent then a particularly attractive halo effect is obtained around the logo or lettering when back lit.

Title: Process and equipment for the automatic alignment of an object in respect of a reference
Inventor: LINGER CLAUDE JACQUES ANDRE
IPC: H01L21/68
Filed: 1983-12-28
Granted: 1988-10-13
Abstract: The alignment system uses a pair of spaced analysis windows (15) for viewing crosses carried by the substrate. Each window uses a photodiode matrix divided into quadrants with a corresponding alignment cross image (IREX) provided at its centre.

Title: Sealing ring for cast iron pipe couplings
Inventor: BUCHER CLAUDE
IPC: F16L17/02
Filed: 1984-09-27
Granted: 1987-04-02
Abstract: An annular elastomer packing 2 for a male-female bell housing type of pipe joint has a trapezoidal foot 12 radially opposite an anchor ridge or flange 8 which seats in a mating groove 5 in the housing, and a tapering truncated body portion 10 joined to the anchor ridge by a shoulder 6 and to the foot by a groove or recess 19. The radial compression of the foot during the initial insertion of the male pipe end serves to firmly anchor the packing via the ridge 8 and groove 5 with the recess 19 accommodating the compressively deformed material, whereafter the continued insertion of the male end radially compresses and axially extends the body portion to ensure a tight seal. This configuration reduces the insertion force and enables greater dimensional variations to be tolerated.

Title: Counterbalanced hinge assembly
Inventor: OPSAHL ALLAN
IPC: B64C1/14
Filed: 1984-02-06
Granted: 1987-12-23
Abstract: The door (20) pivots on an inclined hinge axis, to move upslope through an angle (Beta) and downslope through another angle (Theta) as it opens.  The door moves through these angles in reverse as it closes.  The door is hinged to a torque tube assembly (25) coincident with the hinge axis.  A radial cam with a profiled face is mounted on the torque tube for rotation through the two angles. Springs are mounted in a housing contg. a reciprocable piston and cam follower biassed against the cam face.  As the door moves downward the springs are compressed to store energy which is returned as the door moves back, to reduce the manual force necessary.

Abstract: An apparatus for the burning of solid particles, especially soot particles, separated from the exhaust gas from internal combustion engines has a rotationally symmetrical combustion chamber which coaxially adjoins an ignition burner connected with it by a flame transfer orifice. Fuel and air are metered to the ignition burner through an additional-air line and a fuel line and, as a prepared mixture, they are ignited in the ignition burner and enter the combustion chamber through a flame transfer orifice. In the combustion chamber an exhaust gas partial stream enriched with the solid particles is introduced, and, after the solid particles have been consumed together with the additional air put into the combustion chamber, the exhaust gas is then discharged again as cleaned exhaust together with the remaining combustion products through an outlet tube.

Title: Internal-axis rotary piston machine
Inventor: KRAIC OTTO
IPC: F01C1/10
Filed: 1986-07-14
Granted: 1989-06-15
Abstract: The external rotor of a single-rotation machine has engagement spaces, whose boundary faces in the inward direction form a widening, which is adjacent in an outer region radial thereto to parallel surfaces or surfaces forming a widening in the outward direction. The side walls axially bounding these engagement spaces have a radially outer part, which is cast in one piece with the peripheral parts of the external rotor and an inner part radial thereto, which subsequently reduces to a circular opening the opening surrounded by the radially outer parts, so that the radial seal between side walls and a stationary sealing member surrounded by said opening is located radially within the peripheral parts of the external rotor and a sealing gap in the radial plane between the peripheral parts and the sealing member is avoided. The joining of peripheral parts and the radially outer side wall parts in one piece makes it possible to obtain the necessary high dimensional accuracy required for a good machine efficiency and this is accompanied by low manufacturing costs.
