Title: Liquid application process to granular material - aims liquid at grain curtain flowing out of hopper base
IPC: A23B9/32
Filed: 1975-03-03
Abstract: The process is particularly for the application of preservative chemicals to moist grains of wheat and uses a hopper into which the granular material is delivered at the top. A valve at the bottom of the hopper is actuated by the weight of material in the hopper and discharges the material in a ring-shaped curtain. The liquid emerges from an application unit below the hooper, being aimed so as to strike the falling grains. Means are included for regulating the degree of opening of the valve to match the speed of application of the liquid. The valve can be in the form of an inverted cone thrust against the bottom of the hopper, and shutting when the hopper is empty.

Patent NL-9101544-A (NL)
IPC: H05K3/24
Filed: 1991-09-13
Abstract: This invention relates to a method and apparatus for the selective electroplating of metals on metal or metallised products in an elongated strip. Use is made of an apparatus in which an assembly of a masking belt (15) and the product strip (16) are guided along means for exposing the products to an electrolyte. Masking belt and product strip have been provided with holes distributed in a regular pattern over their respective length's, whilst driving means are provided to lengthwise transport masking belt and product strip. By means of proximity sensors (27,28), signals are obtained which indicate the position of the holes in the masking belt and product strip in positions which, related to the direction of travel of belt and strip are situated up stream and nearby the means for exposing the products to an electrolyte. When the signals obtained from the proximity sensors indicate a deviation from the targeted position of belt and strip in relation to each other, a relative move between masking belt and product strip lengthwise is effectuated by influencing the driving means.

Title: Motion sensor, and alarm system comprising such a motion sensor
IPC: G08B13/14
Filed: 1993-01-27
Abstract: Motion sensor, particularly intended for an alarm system responding to movement, is provided with a housing which is made of electrically insulating material and comprises a chamber, and with three coils surrounding the chamber at different locations. Disposed within the chamber is a magnetically conducting element. The chamber is circular in at least one cross-sectional direction and is preferably spherical in shape. The magnetically conducting element likewise has a circular cross section in said cross-sectional direction and is preferably in the form of a sphere. Disposed in the chamber are means, preferably a viscous liquid, for damping the movement of the magnetic conducting element. The alarm system comprises a processing unit with an oscillator to which the coils of the motion sensor are connected. The oscillation frequency of the output signal of the oscillator is determined by the self-inductance of the coils. A monitoring element monitors the oscillation frequency and is able to derive an alarm signal from a variation in said oscillation frequency.
Patent NL-9401357-A (NL)
Title: Shipbuilding
Inventor: OEVEREN JACOB VAN
IPC: B63H5/07
Filed: 1994-08-22
Abstract: My patent relates to shipbuilding. Currently, all ships are pointed at the front and are round at the rear, where the resistance is located. All fish are round at the front and pointed where the resistance is located (the tail). The change is simple: The propeller is removed and is fitted back-to-front, and the rudder is rotated through 180 degree. The ship then sails in the opposite direction. In the old model, the propeller was in the vacuum created by the ship, whereas now the ship is in the vacuum behind the propeller, thus providing a dual advantage. Also, the susceptibility of the propeller to damage is reduced, especially during push towing, so that the captain of the ship can sit back.

Title: Process for making hydrated peanut products and products -made thereby.
IPC: A23L25/00
Filed: 1978-01-11
Abstract: The shelled peanuts are mechanically peeled dry at ambient temp., the moisture content of the peanuts is adjusted to 3-8% and the peanuts are pressed at 140-350 kg/cm2 withotu breaking them to remove a substantial part of the fatty materials. The partly defatted peanuts are cooked in the presence of pure water, using >=1 pt. peanuts per 3 pts. water, at 65-150 degrees C, if required under pressure, for 10-60 mins. to gelatinise the starch and coagulate the proteins and hydrate the peanuts, which absorb an amt of water equal to their weight. The peanuts are drained or dried and then reduced to pieces. The chopped product may be used e.g. as a coconut substitute; the paste may be used as a base for soups and sauces or in the mfr. of hamburgesr and sausages. The product is stable to storage and the process enables adjustment of the water content to that desired enabling a wider use of the material.

Title: Method for underground gasification of fuel
Inventor: KREININ EFIM VULFOVICH
IPC: E21B43/24
Filed: 1978-12-11
Abstract: Fuel is gasified underground by (a) drilling holes; (b) linking the holes by channels, (c) igniting the fuel; and (d) injecting an O2-contg. blast (I) (for prod. gas formation) simultaneously with a carbon and/or hydrogen-contg. blast (II) (for enriching the prod. gas with combustible components). The blast (II) is supplied through holes in the area of prod. gas withdrawal, i.e. away from the zone of (I) injection. The method is esp. for gasification of coal. Injection of (II) into the prod. gas withdrawal area enables better use of the sensible heat of the hot prod. gas. This is because the heat reduces the steam and CO2 in (II) and decomposes hydrocarbons, enriching the prod. gas in H2, CO, CH4. The prod. gas has a heating lue of above 1000 kcal/m3.

Patent PT-91957-A (PT)
Inventor: ALEXANDER STEPHEN EDWARD
IPC: A61P1/02
Filed: 1989-10-11
Abstract: The problem of formulating a dentifrice which is compatible with a bis-biguanide anti-bacterial agent, for instance chlorhexidine or alexidine, is solved by using a nonionic thickening agent; a nonionic surfactant; and an abrasive which is either a sparingly soluble salt, for instance calcium carbonate, (used in combination with an agent to suppress anion formation), or an essentially insoluble compound, for instance, a silica of low anion content, or a mixture thereof. Preferably, the composition has a flavour which is mainly aniseed, balanced by mints. Preferably during the preparation of a silica containing dentifrice, chlorhexidine and saccharin are added together at an early stage, prior to the addition of silica, to avoid the formation of lumps. Such dentifrices are useful in the prophylaxis and/or treatment of periodontal disease and caries.
