Title: Diesel engine providing even idling - has pedal controlled fuel pump and intake throttle closing to near engine stalling when idling
IPC: F02B3/06
Filed: 1980-01-31
Abstract: The Diesel engine (1) with a fuel injector (4, 5) comprises an accelerator pedal (6) -operated throttle (3) in the air intake (2). The throttle is so arranged that, when the engine idles, i.e. in the rest position of the pedal, and the engine is at normal operating temperature, the flow area through the intake provides only just sufficient air for engine operation. This considerably reduces irregular running due to speed fluctuation. The arrangement may cause the intake vacuum under these conditions to be 0.1 to 0.5 bar. Where the pedal is connected to the fuel injection pump (4) the throttle may provide the air flow as required for greater than idling speeds.

Title: Machine to clean floating rubbish, oil etc. from water surface - has vortex impeller to draw water through filter bucket
IPC: E02B15/04
Filed: 1980-04-22
Abstract: A mobile machine for cleaning the surface of an expanse of water by removing rubbish floating on the surface creates a vortex in the water by using a helical impeller rotating on a vertical axis. Centripetal forces within the Vortex tend to concentrate the rubbish towards the axis of the vortex. A filter funnel bucket at the centre of the whirlpool is used to collect rubbish which is filtered out of the water being drawn downwards through the bucket. Pref. the bucket is suspended from a vertical bar which can be raised and lowered w.r.t. the water surface. The bucket can be adjusted for the collection of hydrocarbons from the surface. Pref. the impeller and its drive motor are housed in a coaxial, annular shroud immediately beneath the screen of the filter bucket. Pref. the bucket discharges its rubbish by pivoting open the screen complete with shroud, motor and impeller. The machine can be used to oxygenate stagnant water by injecting compressed air into the shroud adjacent to the impeller as water is drawn through the bucket. The machine will clean water surfaces of floating rubbish, waste oils etc., partic. in harbour and adjacent to piers and dock walls. The machine can be tractor mounted for clearing water adjacent to dock walls etc., and can operate in very confined spaces. The machine can equally be mounted on a barge for manoeuvring in narrow water-ways.

Title: Machine to wash soil from sugar beet etc. - has gravity flow pipes to recycle water from wash zone to pre-wash zone
IPC: B03B5/56
Filed: 1980-05-08
Abstract: Machine for washing soil from root vegetables such as sugar beet, has a horizontal, cylindrical, rotary drum divided into prewash and washing compartments. The washing zone is encircled by a coaxially, annular reservoir. The reservoir is partitioned into a number of pockets. Each pocket having an opening into the washing compartment via a screening grill. The opening is at the leading end of the pocket when the drum is rotating. At the trailing end of each pocket is a second hole leading to the exterior of the reservoir. The second hole feeds into a pipe which delivers into the prewash compartment adjacent to the partition sepg. the two compartments. The pipes from the annular reservoir pockets to the prewash compartment are pref. inclined to the axis of the drum. The inclination is such that, as a pocket rises during drum rotation, liq. drains by gravity through the pipe to the prewash compartment. The pipes can be straight, helical or multi-cranked. The machine is used for washing soil and clay from root vegetables, esp. beet for sugar refineries. Washing water is recycled from the washing compartment back to the prewash compartment without requiring an external pump. Consequently the machine is cheaper than one which has to use a recycling pump. Operative expenses and maintenance requirements are also reduced.

Title: Continuous casting of slabs in mould with electromagnetic stirrer - which produces horizontal row of circular or oval stirring fields across molten metal in mould
Inventor: ALBERNY ROBERT
IPC: B22D27/02
Filed: 1980-06-27
Abstract: The slab has a rectangular cross-section, and at least one long side wall of the mould is provided with a flat, static, electromagnetic inductor. The inductor consists of a vertical stack of core laminations contg. a row of parallel, vertical grooves, which each contain a vertical conductor; a three-phase a.c. supply is connected to the conductors. The inductor is electrically divided, so a horizontal row of magnetic fields with alternate directions is obtd. The result is that a horizontal row of circular or oval stirring fields is produced, where the dia. or max. dia. is 0.5-2 times the width of the narrow mould walls. The stirring is as efficient as when round billets are cast by electromagnetic centrifugal casting.
