Patent NL-8500724-A (NL)
IPC: A61K9/20
Filed: 1985-03-13
Abstract: The invention relates to a device for the controlled release of one or more active ingredients to a liquid, particularly a controlled release pharmaceutical tablet obtained by compressing a mixture of two granulates in a weight ratio of 30:70 to 70:30, said granulates having particle sizes of 0.4-2.0 mm. One of the granulates, the restraining phase granulate, comprises one or more active ingredients dispersed in a matrix of an insoluble substance, and the other granulate, the housing phase, comprises a soluble material and a penetration rate limiting material, one material optionally having both functions. In the compressed device, the granulates form two distinct phases, each of which is continuous. The housing phase fills large continuous pores in the restraining phase. A zero-order release rate can be obtained with the devices.

Patent NL-9101791-A (NL)
Title: Method for fabricating mouldings from clay
IPC: C04B33/04
Filed: 1991-10-24
Abstract: Object The object of the method described for fabricating mouldings from clay is to produce sewage pipes, building blocks, tiles, roof tiles and the like from residues such as Euro clay, ground gangue, sand, dredgings and fly ash. The base materials can be both primary and secondary base materials. An essential feature is the addition of water-glass. This acts as an alkaline activator. The water-glass reacts with clay and fly ash to produce cement-like minerals, to which the characteristics of the material are due. Method The base materials are blended into a homogeneous composition. This composition is admixed with water to achieve the processability required for shaping. Shaping can be effected in three ways, namely: extrusion, extrusion in conjunction with compression-moulding, and compression-moulding. Each of these three techniques requires a specific processability. The aftertreatment of the moulding may consist of the application of the coating (adjusting the colour) or of a stone-like material (improvement in the wear resistance). The moulding then undergoes a thermal treatment, in the form of steam curing, autoclaving or microwaving. This treatment ensures that the chemical reactions will take place to a sufficient extent. After the treatment, the moulding is ready for shipping and use. An important aspect of the procedure is that residues can be used as base materials, for example uncontaminated or slightly contaminated dredgings. Since the products can be employed, inter alia, as bricks, savings in primary base materials (raw materials) such as clay are possible. Another important aspect is that the process, owing to its simplicity, is not greatly susceptible to malfunctions.

Title: Border
IPC: A47G1/10
Filed: 1992-12-22
Abstract: The invention relates to a border for a flat carrier which is to be suspended in a visible position, comprising profiled sections which extend along the edges of the carrier, at least along the front side of the carrier, and clamping means which are arranged at the corners of the carrier, in order to connect profiled sections to one another, the clamping means being designed to cover the profiled sections at least at the front. As a result of this measure, the connection between two profiled sections is out of sight, so that the saw cuts do not have to satisfy such high requirements. It is therefore possible to market a border of this nature as a self-assembly kit. According to a preferred embodiment, the clamping means are provided with a clamping member which is designed to exert a force directed towards the front against the carrier. This force makes it possible for the profiled sections to be attached in the clamping means by means of clamping.

Title: Clamping device on the ball of a tow hook
Inventor: VISSER GUUS EDUARD
IPC: B60R9/06
Filed: 1994-09-13
Abstract: The invention comprises a clamping device which is part of an accessory which can be fitted on the tow hook of cars. The clamping device is pushed horizontally over the tow hook, and, by simply rotating one vertical bolt with a clamping cup downwards, the ball is clamped securely between the cup and the ring beneath it. The unit is designed in such a way that, when the bolt is tightened, the ball is approximately 3/4 enclosed, with the result that an optimum clamping effect is achieved with the 3 m/m play in the top of the cup and in the bottom of the ring. Furthermore, the clamping device is supported on the vertical section of the tow hook, specifically in such a way that the accessory, in the fitted position, cannot tilt away downwards or sideways. By pushing the supplied locking strip behind the ball and locking it with a padlock, it is virtually impossible to lose the accessory while driving, and the accessory also serves as an antitheft precaution.

Patent PT-78826-A (PT)
IPC: D06B9/06
Filed: 1984-06-29
Abstract: In this process the organic solvents which are obtained in a liquid state in the drying phase are pumped away. The solvents present in the form of a solvent vapor/air mixture are partially condensed by cooling and the fractions of solvent still remaining in vapor form are adsorbed by active charcoal. These adsorbed solvents are recovered by setting up a saturation partial pressure of the solvent in the solvent vapor/air mixture of not more than 0.25 bar. The fractions of solvent adsorbed in the active charcoal are desorbed by means of a solvent vapor/air mixture of the same concentration as in the adsorption process and at temperatures of approx. 100 DEG  to 150 DEG  C.

Filed: 1989-03-16
Abstract: The ski has a device to enhance safety, which is fixed to the upper side of the ski between the tip and the binding. The device (8) has a semi-shell-shaped body with a closed-surface shell wall (22), which widens from a tip (16) to an open end surface (18), and is fixed to the upper side (2) of the ski (4) in such a way that the lower edge (26) of the body rests on the upper side (2) of the ski (4) at least virtually without a gap. In the region of its open end surface (18), the body at least partially overlaps the parts of the ski binding which are at the front in the travelling direction of the ski. By means of the device, due to the large extent of covering of edges of the ski binding which tend to cause injuries, the risk of injury is considerably reduced and, moreover, the ski is given an attractive appearance. <IMAGE>
