Title: Slurry tanker and pump
IPC: A01C23/04
Filed: 1979-06-07
Abstract: A vehicle (10) for use in transporting and pumping farmyard slurry comprises a trailer (10) adapted to be connected to a tractor. A first pump (13) is located at the free end of a jointed and telescoping boom (15) which is pivotally mounted on the trailer (10) so as to be movable between operating and stowed positions. In the stowed position the first pump (13) overlies an inlet hopper (12) of a container (11) for slurry mounted on the vehicle (10). Drive means (16) is mounted on the vehicle and operable selectively to drive the first pump (13) and a drive means power take-off shaft (19) to which a second pump (20) is connected. The second pump (20) serves to deliver slurry to an outlet (30) of the container (11). The drive means (16) is driven by the tractor power take-off shaft. The boom (15) may be moved so that the first pump (13) can be lowered into a slurry pit so as to pump slurry therefrom into the container (11). <IMAGE>

Title: Magnetic compass
IPC: G01C17/06
Filed: 1979-07-11
Abstract: A magnetic compass 10 with eddy-current damping, e.g. a hand- bearing compass, has an annular electrically- conducting damping barrier shell 20 of apertured spherical form at whose centre 17 the assembly of the magnet system 18 and compass card 15 is pivoted at the centre of gravity of the magnet system 18. The wall of the damping shell 20 extends symmetrically or approximately symmetrically above and below a horizontal plane through its centre 17. The centre of gravity of the whole pivoted assembly of compass card 15 and magnet system 18 is below the pivot point 17. This damping arrangement provides greatly improved damping and lower resonant frequency of the magnet/card assembly in pitch and roll, giving greater ease of reading. The compass card 15 is annular and surrounds the barrier shell 20 in a plane passing through the pivot point 17, and the card 15 is supported by a spider 28, 29 which extends below the shell 20 and up through a bottom aperture 22 in the shell to the magnet system 18 to which it is attached. <IMAGE>

Title: Manufacture of rack member for rack and pinion assembly
IPC: B21D53/88
Filed: 1979-10-24
Abstract: A longitudinally extending rack member for a rack and pinion assembly is formed from a tubular metal bar 1 having longitudinally extending grain 9 over the length of the bar within which the rack teeth 4a are to be formed. The rack teeth 4a are formed by collapsing the wall of the bar 1 to close its bore 2 and by coin pressing the collapsed wall between opposed dies so that the metal grain 9a follows the form of each tooth and each tooth 4a is devoid of end grain. For a thin walled tubular bar, a tubular plug can be located in the bore of the tubular bar and the walls of the bar and plug are subsequently collapsed to close the bore of the plug. The walls are coin pressed to form the rack teeth. <IMAGE>

Patent GB-2072757-A (GB)
Title: Fluid turbine having spiral chambers
IPC: F01D1/34
Filed: 1979-12-08
Abstract: A turbine is operated by fluid forces directed on to inclined continuous chamber surfaces which are able to rotate. In rotating the propellant emerges at an angle opposite to the direction of the rotation. At the exit the propellant is deflected from angular surfaces forming reaction chamber or chambers so directed as to increase the rotational forces on the rotor. The flow out of the chambers into an exhaust position is arranged so that the propellant in passing out through holes or slots also increases the force of rotation. A feature of the design is that cooling air may be added to the passage of propellant by arranging for a number of the inlet nozzles to supply cooler air.

Title: Sound synthesizer
IPC: G10L19/07
Filed: 1980-09-24
Abstract: A sound synthesizer in which pulses of a period indicated by a fundamental period parameter are produced by a fundamental period sound source, the output from the fundamental period sound source or the output from a noise source is selected depending on whether a sound to be synthesized is a voiced or unvoiced sound, and the selected pulses are applied to a sound synthesis filter section 16 to synthesize the sound. The sound synthesis filter section is composed of a second- order filter means (57-61, 65-69) which serves as a second- order filter having the zero on a unit circle in a complex plane, means for cascade-operating second-order filter means of different coefficients, and feedback means 41, 42 for feeding back the output from the synthesis filter section 16 to the input side through two kinds of such cascade-operating means, and coefficients of the second-order filters are controlled by control parameters. <IMAGE>

Patent GB-2088601-A (GB)
Title: Recording energy use
IPC: G01R21/133
Filed: 1980-11-24
Abstract: Pulses are generated as a function of the instantaneous rate of energy use, and such pulses are counted during succeeding discrete time intervals to determine the electrical energy used the counts being recorded in digital form at respective discrete locations in a memory (43), which may be in a removable cartridge 41. The counts are summed to provide a grand total energy use value which is stored at another discrete location in the EPROM memory (43) at the end of a recording period composed of a multiple of such succeeding discrete time intervals. The counts are also successively compared and the count for that interval having the greatest energy usage within the period is also recorded on the EPROM (43). At the conclusion of the recording period the cartridge is removed and read to establish the electrical energy consumed at the particular location. The respective times of beginning and end of the particular total time period may also be recorded, as well as the location of the energy use. <IMAGE>

Title: Diffusion station for processing image-transfer materials
Inventor: NEUJENS GEORGES JOZEF
IPC: G03D9/00
Filed: 1981-10-05
Abstract: A diffusion station for the processing of image-transfer materials incorporates an upstanding helix 22 between the convolutions of which an image-transfer-sandwich is introduced. The helix rotates at a moderate speed thereby carrying the sandwich along its axis.

Title: Particulate compositions useful as plant growing media additives
Inventor: BOSLEY JOHN ANTHONY
IPC: C05G3/80
Filed: 1982-08-05
Abstract: Superabsorbent gel compositions useful as plant growing media additives are prepared from a copolymer of acrylamide and acrylic acid salt in a molar ratio of 70:30 to 95:5, cross-linked such that less than 30% by weight of the dry polymer is water-soluble and the gel can absorb releasably at least 15 times its own weight of water. The gel composition is therefore tailored to the needs of an agricultural/horticultural context because it has long-term stability in natural soil, low solubility that would otherwise lead to poor soil properties, and good water absorbency. Preferred gel compositions in foam form are described.
