Title: Apparatus for spreading material
Inventor: MARSHALL CHARLES RICHARD
IPC: A01C3/06
Filed: 1991-06-18
Abstract: Apparatus for spreading material, for example agriculture material such as muck, is disclosed. The apparatus comprises a container (2) in which two rotatable rotors (8, 9) are mounted. The container (2) also has a piston (5) located inside which moves the material towards the rotors (8, 9) which are located at the front of the container (2). One of the rotors (8) is relatively slow moving and comprises four circumferentially distributed arms having blades and protruding sections mounted thereon. The other rotor (9) is located adjacent to a discharge aperture (10) in the container (2) and comprises four rotor arms (10) mounted on an axle (19). In operation, the slow-moving rotor (8) helps circulation of the muck within the container (2) and helps tear up any compacted portions of muck. The rotor (8) also helps direct muck towards the other rotor (9). <IMAGE>

Title: Attenuated phase-shifted reticule using sub-resolution pattern
Inventor: DAO GIANG T
IPC: G03F1/32
Filed: 1993-06-29
Abstract: An attenuated phase-shifted reticle 60 has a checkerboard patters 32 of chromium 32a with open squares 32b of a size below the resolution of the printer (eg 0.1 micron) so that it transmits a substantially uniform, attenuated radiation of reduced intensity, the pattern surrounding openings 21 with features. The features are phase-shifted relative to the sub-resolution pattern, such that light transmitted through them is approximately 180{ out of phase compared with the attenuated radiation transmitted through the pattern surrounding the features. In this way, the pattern acts as a phase-shifter for the features. The pattern may alternatively be in the form of a grating (Figure 5) or concentric squares (Figure 7) and the reticle is used for lithographic printing. <IMAGE>

Patent GB-2286682-A (GB)
Title: Inductive pressure transducer
Inventor: BRAMMER NORMAN
IPC: E21B47/06
Filed: 1995-02-13
Abstract: An inductive pressure transducer 17 senses fluid pressure within a tubular member 13 by passing an alternating current within an inductor coil 23 to generate a magnetic field. The magnetic field passes through a gap 27 between the tubular member and the inductor coil, and into an exterior portion of the tubular member. Stress induced in the tubular member due to the pressure of the fluid therein causes variations in the electromagnetic properties of the material from which the member is made, the magnetic field passing through the member being affected by these variations in such a way that detection of the effect on the magnetic field gives a measure of the fluid pressure within the member. <IMAGE>
