IPC: A01K1/01
Filed: 1982-08-23
Abstract: Apparatus for collecting slurry is adapted for mounting onto a tractor and when so mounted for progressing in a scooping attitude at ground level towards slurry to be scooped up. The apparatus comprises front and rear receptacles (10, 11) whereof that to the front is swingable about a transverse axis from a scooping attitude in which a rear wall (10A) of the front receptacle (10) closes off an open front of the rear receptacle to an inoperative position wherein it is clear of said open front of the rear receptacle to discharge the slurry. A rotating means having squeegee- blades 17 is provided in the front receptacle (10) to sweep up slurry up a ramp (20 or 44) and deposit it into the rear receptacle (11). In a further embodiment the rotating means takes the form of an endless conveyer, Fig. 4 (not shown).

Title: Lathe chucks
Inventor: NOBUOKA AKIRA
IPC: B23B31/177
Filed: 1982-11-03
Abstract: A power-operated chuck for a numerically controlled lathe has a drive gear 22 having a worm gear is rotatably provided on a support axis to act as a drive jaw engaging a chuck jaw 8 having rack teeth thereon engaging the front of said drive gear. A ring gear 23 engaged with the rear side of said drive gear 22 is, rotated by a drive shaft 9 mounted axially of a chuck body, thereby causing said drive gear to be rotated. The chuck jaw is coarsely adjusted radially of the chuck body by said rotation. Also, said drive shaft 9 is axially reciprocable, to cause the drive jaw and drive gear to be finely adjusted in the radial direction in grooves of said chuck body by a wedging action. Therefore, the chuck jaws can be adjusted to suit various workpieces having different diameters. <IMAGE>

Title: Improvements in the regeneration of adsorbents
Inventor: MCCAFFREY DAVIS JOHN ALEXANDER
IPC: B01J20/34
Filed: 1982-12-10
Abstract: A water-saturated adsorbent, especially a zeolite used to dry organic solvents, having a particle size greater than 0.2 mm, e.g. in the range 1.4 to 2.0mm, is regenerated by passing a hot gas through a bed of the sieve. The gas is passed at a superficial velocity of at least 0.5 m/s, e.g. about 1.0 m/s. This is well in excess of recommended values but does not result in an unacceptably high pressure drop across the bed.

Title: Apparatus for sensing the distance between two bodies, one of which is moving relative to the other
Inventor: O'TOOLE TERENCE EDWIN
IPC: G01S15/931
Filed: 1984-01-09
Abstract: An oscillator (2) supplies driving signals to a transmitting transducer (3) which transmits acoustic signals. A receiving transducer (4) is arranged on the same vehicle as the transmitting transducer (3) in such a manner that acoustic signals emitted from the transmitting transducer (3) are not received directly by the receiving transducer (4) but are only received by the transducer (4) after reflection from another vehicle. Signals received by the receiving transducer (4) are amplified and passed via an indicating circuit (6) to a warning device (7) which gives a warning to the driver of a vehicle when the distance sensed between two vehicles reaches a threshold level, and/or indicates the distance between the vehicles. <IMAGE>

Patent GB-2154366-A (GB)
Title: Field effect transistors
Inventor: GARTH SIMON CHRISTOPHER JOHN
IPC: H01L21/326
Filed: 1984-08-16
Abstract: A field effect transistor is constructed so that a short section of the channel next to the drain effectively has a higher gate threshold voltage than the rest of the channel. A CMOS circuit using the transistors can be arranged to pass no current between the supply conductors during a change of state. The drain threshold voltage may be a linear function of the gate voltage thus providing a linear voltage amplifier. The high threshold section may be achieved by irradiating a conventional FET whilst a voltage is applied to its drain causing charge storage in the gate insulation, by establishing a voltage gradient near the drain end of the gate metallisation, or by modifying the channel doping near the drain. <IMAGE>

Patent GB-2154171-A (GB)
Title: Manufacturing a rotor tube
Inventor: ZEILINGER HANS
IPC: B29C53/84
Filed: 1985-01-31
Abstract: During manufacture of a rotor tube the fibers are wrapped in the longitudinal direction and on the outer circumference, in a circumferential direction and the rotor tube is then cured under tension. The wrapped rotor is cured with the rotor tube being radially expanded such that in the idle state of the rotor, the circumferentially wrapped fibers will exert a tangential compressive load on the matrix. As a result, cracking of the matrix in longitudinally oriented fibers will not occur until at substantially higher speeds.

Title: Drying apparatus
Inventor: TRETT JOHN
IPC: A47K10/48
Filed: 1986-11-06
Abstract: A hot air hand drier has a source of hot air which passes the hot air through an outlet. A pivotal flap (10) located in the outlet is movable between an up position, in which it directs the hot air at the hands of the user, and a down position in which it directs the hot air to the face of the user. An infrared detector (16) monitors the hands' position when the flap (10) is in the up position and monitors the face position, due to the presence of a mirror (20) on the rear face of the flap (10), when the flap is in the down position. A pair of microswitches (26 and 28) enable the detector (16) only when the flap is in the fully up or the fully down position.
