Title: Applying fluorine-contg. medium etc. around teeth - using U=shaped troughs fitting over teeth and having inlet connection for medium
IPC: A61C19/06
Filed: 1982-04-13
Abstract: The accessory is intended for applying a treating medium, such as a fluorine-contg. agent, around the teeth of a patient. It comprises two U-shaped trough-section members in transparent soft material which fit over the upper and the lower teeth respectively, and a connection via which the medium can be evenly distributed within the troughs. This connection may have a common central inlet duct and branch ducts leading to the respective halves of each trough, pref. via constrictions positioned and dimensioned such that the medium is uniformly distributed. The branch ducts may be individually closable. The two troughs may be separate components.
Patent NL-8402020-A (NL)
IPC: A01B33/06
Filed: 1984-06-27
Abstract: A soil cultivating implement intended primarily for the production of seed beds comprises a row of power-driven rotary soil working members (3) which row extends substantially horizontally perpendicular to the intended direction of operative travel (A) of the implement and a ground roller (15) which is located to the rear of said row of members 3) with respect to the same direction A, the ground roller (15) being upwardly and downwardly displaceable in bodily level relative to the soil working members (3) by moving supporting arms (14), which carry it, about horizontally aligned pivot pins (23). In order to be able to use inexpensive parts to accomplish a change in the level of the ground roller (15) whilst rendering that operation simple and without requiring any great manual effort, supports (18) project rigidly upwardly and rearwardly from side plates (12) of a hollow frame portion which rotatably supports the soil working members (3) and each support (18) is embraced by the limbs of a narrow forked guide (16) that extends upwardly from a pivotal connection (17) to the corresponding supporting arm (14). Each guide (16) is formed with staggered rows of holes (20) and retaining pins can be entered through appropriate holes (20) beneath the lower edges of the supports (18) to determine the maximum upward pivotal movement of the supporting arms (14) about the aligned pivot pins (13) which is possible. If desired, further retaining pins may be entered through appropriate holes (20) immediately above the upper edges of the support (18). A screen (25) extends throughout the working width of the implement immediately in advance of horizontal carriers (4) of the soil working members (3) at the horizontal level of those carriers and has strip-shaped track-disruption means (26) adjustably secured to it to break up the wheel tracks of a tractor or other vehicle which moves the implement in the direction (A) when it is in use.

Patent NL-8801593-A (NL)
IPC: C08L77/00
Filed: 1988-06-23
Abstract: Impact resistant polyamide compositions containing more than 45 wt.% polyamide and relatively minor amounts of an impact modifier. The impact modifier is an elastomer with groups that are reactive with respect to the polyamide. The impact modifier has an adverse effect on the high-temperature properties, which were already poor. According to the invention, compositions of polyamide, impact modifier and a copolymer of a vinylaromatic compound, in particular styrene, and maleic anhydride have improved high-temperature properties while maintaining good impact resistance.

Patent NL-9101208-A (NL)
Title: Protective cap
IPC: B23Q11/06
Filed: 1991-07-09
Abstract: The invention relates to a protective cap for a circular saw machine, with which it is possible to saw into concrete and rock using diamond saw blades or abrasive wheels, it being possible to suck out the remainder products which are released in the process, such as dust and water mixed with grindings, in such a manner that these products are not released into the working environment. This object is achieved by the fact that the invention is provided with a pivoting section which, in combination with a depth-adjustment mechanism, closes off the protective cap in such a manner that the remainder product can be extracted, while it remains possible, due to the use of a guide which is mounted on the pivoting section, to saw at right angles and in a straight line despite the fact that it is no longer possible to see the saw.
