Patent NL-7401638-A (NL)
Title: Photographic colour image diffusion transfer process
IPC: G03C8/52
Filed: 1974-02-06
Abstract: In the prior art, developers are used to form colour images by diffusion transfer; esp. useful are azo and anthraquinone dyes containing hydroquinonyl (HQ) gps. Oxidation of the HQ to quinone (e.g. by atmospheric O2) affects the light stability of the resulting image. This effect is pH-dependant: if the pH is lowered to a level where alkaline oxidation cannot occur, the light stability of the image is greatly improved. Also, if the alkalinity is reduced by diffusing the alkali ions to an adjacent layer where they are capture and held, the image has enhance brilliance, clarity and luminosity. A means of lowering the pH is provided by a polymeric acid layer into which the excess alkalinity is absorbed, provided as a layer between the image layer and the support. This contains sufficient acid groups to reduce the pH from 13-14 (its initial value) to ca. 5-8.
Patent NL-7406864-A (NL)
Title: Workpiece indexing setting mechanism - performs quick-traverse motion before slowing down and then stopping in exact position
IPC: B23Q16/00
Filed: 1974-05-22
Abstract: The mechanism is particularly for indexing workpieces between machining stations, traversing first quickly and then flowing down before finally stopping in the exact position. The workpiece jig is driven along a stationary base and a changeover mechanism successively slows it down and halts it in the precise position desired. The changeover mechanism can have a first switch with a cam so coupled to the travel mechanism as to rotate with it, and in contact with a follower. A further switch reacts to the follower position and alters and travel speed.

Title: Cement grout obtd. from gas washing muds - uses lime and limestone added for washing and fly ash in the gas
IPC: C04B7/24
Filed: 1975-02-07
Abstract: The parent patent described removal and use of washing muds obtd. from washing off-gases with lime or limestone to remove sulphur oxides. The muds which contain sulphites and/or sulphites are dehydrated and treated with lime and/or fly ash to give cementitious compsns. comprising 30-90% solids including 0.25-70% alkaline earth sulphite, 0.25-70 wt % alkaline earth hydroxide and 10-99.5% fly ash. This mixt. was used for grouting or pointing of mortar layers on brick buildings. In this addition patent, the mud itself can provide part or all the alkaline earth hydroxide and/or the fly ash necessary to provide the stoichiometric excess of lime or limestone used in the washing and subsequently available for reaction. Similarly the fly ash need not be separated from the off gases before washing and this flay ash is then available to the reaction. The residual matl. has a pozzolanic activity equal to 10-99.5% of fly ash according to ASTM C 618. There is no need to separate the fly ash before operation and the lime needed may be incorporated at the washing stage.

Filed: 1988-10-12
Abstract: At their ends, the frame parts (2) of the frame have connecting lugs (4, 5) which are arranged at a different height. During assembly of the frame, two frame parts (2) lie next to one another, the connecting lugs (4, 5) of which lie one above the other at a distance apart and are connected to one another by a screw connection (13). So that the frame parts (2) are connected to one another in a positive-locking manner, the frame is turned upside down and a liquid, pasty or granulated filling material is poured into a recess on the underside of the higher connecting lug (5). The filling material also flows into the bore (6) for the screw connection (13), which bore (6) is covered by a washer (16). After the filling material has solidified, the frame can be transported either in this state or in the dismantled state and put together again in the same manner. Due to this type of assembly, mechanical working of the frame parts 2 can be dispensed with.
