Title: Synthetic resin-coated tube - by allowing resin powder to fall on advancing, rotating heated tube and heating resin coating
IPC: B05C19/04
Filed: 1972-06-26
Abstract: Continuous coating of the external surface of a tube with a thermoplastic or thermosetting resin, which is initially in a powdered state, is effected by advancing the tube as it is rotated, >=the external surface of the tube being heated to a temp. above the melting or bonding temp. of teh synthetic resin, allowing the provided synthetic resin to fall on the tube from >=1 fixed positions disposed above the advancing tube, and heating the material applied to the tube to effect melting or curing of the coating. Spec. the tube is carried mechanically by a continuous helical movement, and is passed into a heating device so that at least the zone of the tube adjacent to its external surface is heated to a temp. above the melting or bonding temp. of the synthetic resin. The heated tube passed below a device which allows a measured amount of the resin powder to fall on the heated tube, and the tube is passed into a heating device which heats the external surface of the coating on the tube to a temp. above the melting or curing temp. of the resin. The coated tube is cooled by allowing a continuous sheet of water, pref. at a low velocity to fall on the ocated tube so as to cover the tube with water. Enables synthetic resin coatings to be applied economically in a single passage to tubes of great length and opt. small diameter, without requiring manipulations. The coating is uniform and several different coatings can be applied.

Title: Root crop lifting machine - passes two small tubers between crusher rollers to prevent re-germination
IPC: A01D17/10
Filed: 1974-01-11
Abstract: The machine is particularly for potatoes, having digger members delivering to a lifting conveyor in turn discharging to one or more other conveyors, with openings allowing loose earth and too small tubers to fall through. Underneath these conveyors (10, 11) a further conveyor (14) is mounted, onto which these tubers fall. At the discharge end of this conveyor are a pair of rollers (15, 16) with a gap between them and driven independently in opposite directions at different speeds. Any small tubers are squeezed in the gap between them. One roller can run at approximately three times the speed of the other, and can be spring-loaded towards it, and the rollers can be grooved. Thus the small tubers are prevented from germinating again.
Patent NL-8102739-A (NL)
Title: Stirring installation for liq. esp. sewage water - has reservoir with supply tubes having suction-holes through which air is drawn by kinetic energy of the liq. to provide intense mixing
IPC: B01F33/40
Filed: 1981-06-05
Abstract: A stirring installation for a liq. comprises a reservoir with a supply and return, (some of which is pumped back into the reservoirs); the supply being a vertical tube, immersed as deep as possible in the water, with one or more suction holes, (for air or another gas), in its wall at a determined distance above the surface of the liq. in the reservoir. The presence of kinetic energy from the returning liq. is used to suck-in air. The air is supplied to the vertical tube above the liq level, so that over the whole tube, an intensive mixing of air and liq. takes place. The installation is esp. for use in the treatment of sewage water. Advantages over conventional methods are that there is no mechanically-driven stirrer required; thus energy is saved, no noise is made, and no accurate temp. sepn. is required.

Title: Supermarket shopping trolley with inbuilt bar code reader and memory - can have memory contents compared with laser scan at checkout without removing articles
IPC: G07G1/00
Filed: 1988-04-08
Abstract: The shopping trolley (10) has a wheeled support frame (11), rectangular wire basket (12) and a pushing handle (13) between two angled arms (14). Mounted on the handle is a portable bar code processor unit and memory (15) connected via a coiled flexible cable (17) to a hand-held bar code pick-up unit (19).

Title: Towing support with gearbox
Inventor: BENTRUP OTTO THEODORE
IPC: B60S9/08
Filed: 1990-05-18
Abstract: A towing support with gearbox, having gears fixed axially in the gearbox, including larger and smaller input means fixed axially on an input shaft and smaller and larger output gear elements of a set of gears fixed axially on the transverse output shaft for the actuation of bevel gears for the lifting screw in the telescopic-leg subassembly. The input gears mesh constantly with their respective, coinciding output gears. The change between the high-speed, low-torque output and low-speed, high- torque output is achieved through the axial movement of the input shaft inside and with respect to the hubs of the input gears. This input shaft has a transverse male transmission bolt which meshes selectively in the interacting female transverse actuating grooves with inclined walls on the inner axial ends facing the axially fixed input gears. <IMAGE>

Patent PT-99027-A (PT)
Inventor: JENSEN BRIAN VANG
IPC: B65D5/74
Filed: 1991-09-23
Abstract: The invention relates to a drip-catcher for, for instance, a bottle and intended for preventing dripping and drops seeping from the bottle orifice during pouring. The drip-catcher of the invention simply consists of a piece (1) of flexible and elastic foil material, preferably plastic material foil having the thickness of 0.1-0.2 mm. The diameter of the piece of material may be 60-80 mm. When used as a drip-catcher the piece of material is rolled into an oblong cylindrical form and inserted in the orifice of the bottle. Due to its elasticity the piece of material will positively engage the orifice and constitute a tube-formed outlet spout. Due to the small thickness of the foil material and its liquid-repellent nature this spout cuts off the jet very efficiently and is also a very efficient drop-catcher. The drip-catcher of the invention is extremely simple and cheap. Its use is uncomplicated and it is universally applicable because the piece of material adjusts itself to the bottle orifice irrespective of its size. The effect of the drip-catcher is remarkable due to the small thickness and liquid-repellent surface of the material.
