Title: Process for preparing storage-stable aqueous dye solutions of water-soluble reactive dyes
Inventor: LACROIX ROGER DR
IPC: C09B67/54
Filed: 1983-08-05
Abstract: Described is a process for preparing storage-stable aqueous dye solutions of water-soluble reactive dyes starting from an aqueous solution or suspension of the crude reactive dye, which is concentrated and at least partially desalted (demineralised) by means of membrane separation processes. The process is characterised in that some of the water which is removed from the dye solution or suspension during the membrane separation process is continuously replaced with demineralised water, and the level (content) of calcium and magnesium ions in the dye solution does not exceed a value of 0.01% by weight. The concentrated and desalted dye solution is stabilised by addition of a polyphosphate or dihydrogenphosphate/polyphosphate buffer; if necessary, a component that improves the water solubility of the dye is added. The preparations thus obtained are satisfactorily storable for several months at temperatures from -10 DEG C to +40 DEG C.

Patent CH-616781-A5 (CH)
Title: Electrical power circuit breaker having adjustable interrupter contacts
Inventor: SPIEGEL HUBERT
IPC: H02B11/04
Filed: 1977-06-10
Abstract: Each adjustable interrupter contact (11) is attached to the associated switch pole (12) by means of three screws (21, 22, 23) which are parallel to the contact axis (28). In this case, these screws (21, 22, 23) in each case pass through one of three straight slots (25, 26, 27) in a contact flange (20) which runs transversely with respect to the contact axis (28). In this case, the width F of the centre slot (25) corresponds to the diameter F of the screw passing through it, while the width F+S of the two side slots (26, 27) is greater than the diameter F of the screw (22, 23) passing through them. Thus, the interrupter contact (11) can be displaced along the slots (25, 26, 27) when the screws (21, 22, 23) are loosened, and/or can be pivoted about the centre screw (21). The adjustment capability which can be achieved in consequence can be limited in an objective manner by dimensioning the length and breadth of the slots with respect to the screw diameter. The dielectric strength between adjacent phases can remain virtually uninfluenced. <IMAGE>

Title: Preparation of degradable micropellets, containing biologically or pharmacodynamically active material, by means of a polymer degradation reaction of dispersed systems
Inventor: HEIJNSBROEK ROGIER
IPC: A61K9/16
Filed: 1976-07-16
Abstract: There is described a process for the preparation of micropellets synthesised from a biologically degradable polymer support material which have a particle size in the sub-micrometre to millimetre range, and which contain a biologically or pharmacodynamically active substance. The liquid monomeric phase is dispersed in an inert phase in the presence of the said active substance and solidified by means of a polymer degradation reaction. As a result, the active substance is incorporated in the polymeric support material or is present embedded in the resulting micropellets in free form. As the polymeric support material is biodegradable, the micropellets are very suitable for use in human and veterinary medicine, in particular if the active substance is to be released with a delay. The smaller particles are very highly suitable, because of their size, for an injectable parenteral administration in medicine.

Title: Device for projecting slides
Inventor: EPITAUX JACQUES
IPC: G03B23/04
Filed: 1976-08-03
Abstract: The equipment includes a channel (17) intended to receive loose slides and in which channel are arranged a separating member (18) and, on each side of the latter, two movable transverse walls (21 and 22) connected by a spring in order to keep the pack of slides in place. Means are provided for moving the separating member (18) for inserting a slide into or withdrawing a slide from the projector. Two rollers (33 and 34), mounted elastically side by side at the entrance of the projector, move apart elastically under the action of a slide. A device (37/38) permits respectively the extraction of a slide from and reinsertion of a slide into the pack. Separating means (20 or 66) move the slide to be inserted away from the adjacent slide, so as to insert a single slide at a time. <IMAGE>

Title: Domestic waste water and sewage evacuation device - using submerged turbine pump and level switch
IPC: F04D7/04
Filed: 1973-07-17
Granted: 1975-02-14
Abstract: Evacuation device for domestic waste water and sewage is intended for use in cases where the lowest point of the installation is below the level of the sewer or the septic tank. Appts. consists of a welded metal tank, which acts as a reservoir, and a turbine pump driven by an electric motor with a vertical shaft; the motor is controlled by a level switch and a time lag-relay. The wate water enters at the top of the tank and is pumped out through the pipe; it reaches the pump by an opening and the volute, surrounding the pump turbine, is always filled so that there are no starting problems, and the pump is always primed. The tank and its connections are all welded and of simple construction; the cost is, therefore, low. It can rest on the ground and takes up little space.

Abstract: A new sustained-release form is described for the oral administration of drugs which produce a pH value of less than or equal to 5 when in aqueous solution. The new sustained-release form can also be used for drugs which do not produce an acid pH when in solution but which can be formulated with excipients of acid pH. The formulation comprises essentially: a) a nucleus constituted by a continuous rigid polymer matrix which incorporates the drug, this polymer matrix being insoluble at acid pH values but biodegradable at pH values exceeding 5. b) a first film which is applied over the nucleus and is arranged to regulate the diffusion of the drug by means of a membrane effect; c) a second film which does not obstruct the diffusion the drug, which protects the preceding film and which possibly carries a quantity of drug to compensate for the release time lag.

Inventor: RICHARDS NORMAN D
IPC: H04N1/64
Filed: 1987-12-23
Abstract: Pixel information representing an image for display is coded using data compression. The data compression consists in obtaining the pixel information as a first matrix of high resolution pixel values, subtracting from this first matrix a second matrix composed of lower resolution pixel values, produced by low pass filtering the first matrix, to produce a third matrix of difference values, sub-sampling the second matrix to produce a fourth matrix of less density lower resolution pixel values and coding the third and fourth matrices. Complementary decoding consists in restituting the second matrix by interpolation filtering the decoded fourth matrix, and combining the restituted second matrix with the decoded third matrix. Loss of accuracy in the decoding method is reduced by coding and then decoding the fourth matrix during the coding method before it is interpolated to full pixel density to form the restituted second matrix which is subtracted from the first matrix to produce the third matrix of difference values. In this way, any sub-sampling and interpolation errors in the restituted fourth matrix occur in both the coding method and the decoding method and therefore cancel out. Figure 3 illustrates the coding method including these coding and decoding steps.
