Title: Single-phase pesticidal liquids containing a pesticide - and a vegetable- or animal wax
IPC: A01N25/04
Filed: 1968-07-30
Abstract: Known pesticides such as DDT malathion etc., dissolved in a solvent in which a vegetable- or animal wax is dissolved form a single-phased pesticidal liquid. A mixture of lipophilic- and hydrophylic emulsifying agents is added. May be used against harmful organisms such as insects, mites, fungi or weeds in agriculture and horticulture. The liquids are useful for misting from aeroplanes in low concentrations. Addition of waxes reduces the phytotoxicity of the low-volatility solvents used, such as ketones, terpenes, high-boiling aromatic hydrocarbons or high-boiling alcohols. Addition of 0.5.5% of the wax considerably reduces the phytotoxicity.

Title: Causing difficultly fluidisable powder to flow - by the simultaneous application of gas and mechanical vibration
IPC: B65D88/64
Filed: 1977-07-05
Abstract: Powders whose cohesiveness makes them difficult or impossible to fluidise by means of a gas alone are caused to flow by the simultaneous application of gas and mechanical vibration. The vibration and the air input take place at the same location. The air is introduced via a porous plate horizontally placed in a powder silo or bunker. The plate is connected to the walls of the silo by means of a flexible membrane and is caused to vibrate at the required frequency. A hole in the centre of the plate provides the outflow for the fluidised stream of powder and air. The silo can then be connected to a conventional pneumatic powder conveying system. The system can be applied to the storage and transportation of perishable goods such as powdered milk where mass flow of the powder through the system is essential to prevent the accumulation of material in dead zones and where the cohesion of the powder particles is such as to rule out the conventional vibratory systems.

Title: Turbo compressor system for motor vehicle - provides continuously variable transmission using ratio between pulley diameters in belt drive system to control compressor
IPC: F02B37/18
Filed: 1987-11-11
Abstract: This vehicle engine (1) is coupled to the road wheels via a conventional friction clutch (50) and a continuously variable transmission system (16). The transmission system is of the type which has two pulleys (17, 18) connected by a Vee-belt (21). One (22) of the two plates which make up the primary pulley (17) is moved away from the other to alter the transmission ratio. The in-take air to the engine is compressed (8) by a turbine (7) driven by the exhaust gas flow. A special turbine bypass valve (119 is used between the exhaust manifold (5) and the twin exhaust pipes (6). When the transmission ratio is high, the valve is operated by the differential pressure between the inlet manifold and a closed volume (12) behind a spring-loaded membrane (13). When the primary pulley plates move together to raise the ratio, a pivoted rod (24) increases the spring pressure on the membrane to close off more of the by-pass valve port (10).

Title: Method for preparing a liquid product and device for using this method
IPC: A47J31/06
Filed: 1991-10-30
Abstract: In use, the closed reservoir 1, which contains a specific quantity of a substance which is intended for the preparation of a drink by dissolution or extraction with a liquid, is placed in a liquid-holding component which comprises a frustoconical cup 9. The assembly formed in this way is placed in a housing 21 of a "spoon" of a coffee-maker. The top side of the reservoir 1 is perforated by a perforating and injection component which injects a pressurized liquid into the reservoir 1. The underlying membrane 2 of the reservoir is subjected to distortion by the action of the pressure produced in this way and is pressed against perforation points 13 on the bottom of the cup 9. The liquid flows into the housing 21 and can be collected in drinking cups. In this way, it is possible to optimize the contact time between the substance which is present in the reservoir and the liquid which is supplied for its dissolution or extraction. <IMAGE>
Patent NL-9200631-A (NL)
Title: Plant pot suitable for use in hydroponic cultivation
IPC: A01G31/00
Filed: 1992-04-03
Abstract: The invention relates to plant pots made from inorganic material, such as rock wool, which are suitable for use in hydroponic cultivation. Plant pots of this nature are in the shape of a parallelepiped with an opening which opens out in the top surface of the parallelepiped and is intended to hold a seedling. The underside of the parallelepiped, which is remote from the top surface, is provided with cutouts, each cutout opening out in only one of the four upright sides of the parallelepiped or in two adjoining upright sides of the parallelepiped, and the cutouts are not connected to one another. The design of the plant pots according to the invention means that it will be impossible for a flow of cold air to be developed beneath the plant pots, while the cutouts arranged on the underside of the plant pot still ensure adequate drainage of the plant pots, thus allowing optimum growth of the roots of the seedlings which have been planted in the plant pots. The cutouts - parallel to the base surface - are advantageously semicircular in cross section which opens out in an upright side of the parallelepiped. Plant pots which have a cutout on the side of the parallelepiped are most preferred.
