Title: An automatic selection apparatus for sheet material
Inventor: KONISHI KOUJI
IPC: B41F33/14
Filed: 1987-04-23
Abstract: Sheets 12 eg paper are continuously and automatically determined to be either good or bad by apparatus which carries the sheets 12 one by one with their leading edges held by a gripper 28, through optical type defect detection devices 14, 16, 18. Vibration of the sheet material is reduced and the defects can be detected exactly. A controller receives signals from the defect detection devices and drives switching devices 40 or 43 which open and close the grippers at a defective sheet discharge position 36 or a good sheet stack position 38 respectively. …<IMAGE>…

Patent GB-2197086-A (GB)
Title: Laser system
Inventor: HANNA DAVID COLIN
IPC: H01S3/23
Filed: 1987-09-22
Abstract: A laser system 10 comprises a laser oscillator 12 producing an output amplified by a laser amplifier 20, which produces phase and polarisation degradation. The amplifier output is divided into two orthogonal polarisations in respective beams by a birefringent prism 22, one beam being subsequently rotated in polarisation by a half-wave plate 32. The beams are recombined in a Brillouin cell comprising a waveguide 36 consisting of two mirrors 40 and containing high pressure methane. The beams are arranged to cross at the waveguide wider end or entrance, and they subsequently undergo multiple reflections at the mirror surfaces before converging to a common line focus 46 of the lens 34. Between crossover 48 and focus 46 they overlap partially or wholly. They consequently produce a common phase conjugate Brillouin back-scattered beam which retraces the original beam paths to amplifier 20. <IMAGE>

Title: Device for moving bales
Inventor: FITZELL RAYMOND
IPC: A01D87/12
Filed: 1987-10-05
Abstract: A loader tractor on which a bale moving device is mounted is advanced towards a cylindrical bale 24 with retaining rollers 14 on an arm 16 in a raised position. A rotatably mounted roller 26 of a lower bale support 12 is pushed partially underneath the bale 24 and the rollers 14 on the arm 16 are caused to move downwardly to grip the bale by actuation of ram 28. A post 18 to which the support 12 and arm 16 are connected is then caused to be rotated in an anti-clockwise direction about a pivot 32, and the front boom 22 of the loader tractor can then be raised to transport the bale. Release of the bale can be reversal of the above described sequence. The pivot 32 may be dispensed with, and the roller 26 be reduced in diameter to enable it to be pushed further under the bale with a lengthening of the support 12. <IMAGE>
Patent GB-2215931-A (GB)
Title: Amplifying devices
Inventor: KERSLAKE RICHARD MICHAEL
IPC: H03F1/30
Filed: 1988-03-22
Abstract: In an amplifying device e.g. an amplifier or comparator, an input offset of a differential input circuit 5-12 is reduced by temporarily operating switches 3, 4 to apply the same potential to the inputs of 5, 6 and by activating an offset voltage adjustment circuit 15, 19, R1-RN-1; T1-TN to adjust the balance of the input circuit in steps until the output signal at 13 is less than a predetermined small value or changes in polarity, the setting of the adjustment circuit being maintained thereafter during normal operation of the device. A gate 15 is enabled by outputs from 12, 18 to pass clock pulses to a counter 19 whose output causes an appropriate one of transistors T1-TN to conduct to apply different shunt resistors across 9, 11 until the change in output at 13 blocks gate 15. The adjustment may be made on power-up and periodically. Only one of resistors 9, 11 may be variably shunted by the adjustment circuit. The counter may be an up-down counter. <IMAGE>

Patent GB-2221262-A (GB)
Title: Improvements in or relating to sealing
Inventor: WAYNE JOHN
IPC: F16J13/24
Filed: 1988-07-26
Abstract: A sealing arrangement for a sump includes a bolt 10, a seal 12, a washer 14 and a nut 16. The four components are assembled prior to insertion into an opening. The effect of tightening the nut causes the tapered head of the bolt 10 to be partially drawn through the seal. This causes the seal to expand outwards with the result that three sealing points are made by the one single action. Firstly, the tapered head 18 creates a seal with the seal ring, internally. Secondly, the lip 30 of the seal hub is pressed over the internal surface 38 of the sump, evenly around the sump hole, creating an internal seal. Thirdly, the base section 28 of the seal, contained by the washer, compresses against the outer surface 24 of the sump, evenly around the sump hole, providing an external seal. <IMAGE>

Title: Toxic waste disposal to an abyssal plain
Inventor: ERIKSEN KARL ARNE KJELL
IPC: B09B1/00
Filed: 1989-02-10
Abstract: A chamber 3 within the body of a floating vessel (i.e. a ship) is open to the sea at the bottom but sealed from the atmosphere at the top and by variance of the internal air pressure sea water level within the chamber can be varied. A hinged door 4 partially fills the bottom of the chamber 3 and is a platform for filling of collapsible flexible disposable containers 5 with toxic or non-toxic slurry pumped from tanks 2 within the ship. During filling of the container sea water level is raised to support the said container. When filled the container is sealed and by tilting of the door 4, the container slides downwards and falls to the seabed. Descent speed is regulated by built in flaps or pockets and direction assisted by steering fins.   <IMAGE>

Title: Axial pin tumbler cylinder lock with cruciform key/keyway.
Inventor: WANG MAO-HSIUNG
IPC: E05B27/08
Filed: 1991-07-12
Abstract: An axial pin tumbler cylinder lock has a cruciform key 9 and keyway 12. Two cylindrical plugs 1, 2 sit in a cylindrical barrel 6 and are provided with bores 13 which house the tumblers 3, 4. The junction between the plugs defines a shear line which when cleared by the tumblers allows relative rotation of the plugs. The tumblers are biased by springs 5 away from the keyway opening. The key is inserted in the keyway and rotated until its arms 91 with billing 912 are underneath the tumblers. The key is then pushed towards the opening of the keyway by plate 71 which urged by spring 72, and the tumblers are pulled into the required position by the billing 912 on the outer edges of the arms 91, to allow relative rotation of the plugs and opening of the lock. The tumblers are of two part form 3', 4, opening of the lock being possible when parts 3 are wholly within plug land parts 4 are wholly within plug 2. <IMAGE>

Title: Sample analysis apparatus and method.
Inventor: DOWSETT MARK GRAEME
IPC: H01J37/30
Filed: 1991-07-25
Abstract: An apparatus for analysing the surface of a sample (1) by means of irradiation of the sample by a primary beam includes means for displaying a visual image of the surface of the sample, e.g. on the VDU of computer 15, together with means (3, 5) for varying the position of the beam on the sample (1) such that material is ejected from a series of different points over the sample dependent on the image. The dwell time of the beam on each pixel of the sample may also be varied. In an arrangement described for mass analysing regions of a semiconductor sample, secondaries from a primary beam incident on the sample are used to form an image of the sample on a computer VDU screen and a mouse is used to define areas of the image it is desired to analyse. The results of the analysis from corresponding areas of a number of identical transistors, for example, may be summed to obtain a more precise depth profile of the dopant in the region of interest. <IMAGE>

Title: Optical instrument mount
Inventor: GREBE VOLKER
IPC: G01S7/481
Filed: 1991-07-31
Abstract: An optical instrument comprises a housing and at least one optical assembly enclosed by said housing and mounted on a stage plate 5. The stage plate is supported on the base plate 1 with the aid of supporting means 2, 3, 4 which guarantees on the one hand a precise fixing of the stage plate compared to the base plate and thus the housing, and on the other hand allows the base plate to distort eg under high temperatures without a transfer to the stage plate. There are three supporting structures of different kinds which fix three different points by ball-and-socket type joints. Upon the disconnection of the third supporting structure 4 the stage plate can be lifted like a lid around an axis which is the middle axis of the first and a second supporting structures 2, 3. The optical assembly uses a split laser beam to effect Doppler shift measurement of a moving liquid surface or solid body eg 10 measure length and/or velocity of a rail produced by rolling. <IMAGE>
