Title: Fruit or bulbs sorting mechanism - has belts attached to rocker shaft pulling spring-loaded trough from rest position
IPC: B07B1/34
Filed: 1974-02-04
Abstract: The mechanism for handling tubers etc., has a frame with a sorting trough running mainly horizontally and with bottom openings in it and spring-loaded into a rest position. The trough is moved to and fro by a mechanism at an angle to its base, having a continuously rotating cam shaft actuating an arm fixed to a rocker shaft running along the trough. This has members transmitting movement to the trough at several different points, in the form of belts (8) attached to the trough (2) and to the shaft (4), being preferably passed part of the way round the latter. Thus as the cam lifts the arm the belts are wound part of the way round the rocker shaft and pull the trough from the rest position, to which the spring returns it as soon as the arm passes the cam lobe.

Patent NL-7613563-A (NL)
IPC: A24D3/02
Filed: 1976-12-07
Abstract: Cigarette filter units are made in a long strip with alternate portions of fibrous and pourable filter material. The fibrous portions are first attached at spaced intervals to a sheathing strip which is wrapped practically right around them to form a cylinder with regular empty spaces between the fibrous portions and openings into the spaces. In a special unit, air is extracted from these spaces so that when the spaces enter a chamber containing pourable filter material, they suck the material in to fully fill the spaces. Excess filter material is brushed off the filter unit, and a sealing strip is stuck over the openings.

Abstract: A testing strip for seeded culture medium, partic. in a Petri dish, and esp. to assess the microbiological reaction between bacteria or pathogens and antibiotics etc. comprises several pref. 3 to 5 coplanar test panels pref. discs, each impregnated with an antibiotic or other reagent to be tested. The panels are mounted separately, one at the extremity of each of a corresp. number of branches extending from a longitudinal support bar. Each branch is treated to provide a barrier preventing the passage of reagent from a panel to the support bar. The barrier is pref. formed by impregnating the branch with wax, paraffin wax, a resin, a silicone or a plastic. Locating lugs are pref. extended outwards from the support bar to serve as abutment locators against the side wall of a P etri dish. The locator tips and disc test panel centres are pref. located on arcs of concentric circles. Used in microbiological medical research to assess the resistance of bacteria or pathogens to treatment with antibiotics etc. The test strip provides a multi-disc assembly to prelace an equivalent number of separate test disc. The strip automatically locates discs on a medium in a P etri dish, saving location time, ensuring accuracy or positioning and flat contact with medium.

Title: Foamed materials using low boiling expanding agent - controlled accurately in quantity by two positive displacement pumps
IPC: B29C44/34
Filed: 1979-07-02
Abstract: The controlled feed of the expanding agent in a process for manufacturing foed material is effected by a positive displacement pump. The expanding agent is for pref. a liquid with a low boiling point. Pref. the expanding agent is supplied to the pump at practically constant pressure. One or more of the components for the foam are delivered at the same time to the pump. For pref. two pumps are used in series.

Patent NL-8600048-A (NL)
IPC: D06F75/24
Filed: 1986-01-13
Abstract: A steam iron comprises at least two heating elements (4, 6), of which at least one element (6) serves for heating a steam boiler (5) for steam production and at least one other element (4) serves for heating the sole plate. In order to obtain a substantially higher heat transfer between the iron and the fabric the iron is constructed in such a way that the heating element(s) for steam production deliver(s) a higher power than the element(s) for sole-plate heating. Suitably, the total power of the heating elements is at least 1400 W. The transfer of heat from the iron to the fabric is effected by steam condensation within the fabric, which proceeds considerably faster than by thermal conduction.
