Title: Window blinds with variable inclination slats - has rod supporting elements for thin folding elements pivoting on swivel pins
IPC: E06B9/302
Filed: 1975-12-17
Abstract: The slatted window-blind construction has a system for controlling the inclination of the slats which comprises at least one group of rigid supporting elements each mounted to pivot about a swivel pin extending from the rectilinear edge associated, with the groove of one of a group of thin elements. It cooperates with an abutment extending from the free edge of the lower adjacent thin element. A connecting means fastens the free ends of these supporting elements to one another to control simultaneously their pivoting and inclination and/or the mutual interconnection of the thin elements each time these latter are in an unfolded position.

Title: Semi-crystalline silicon photovoltaic cell - having large surface grains and junction extending into grains and along boundaries
IPC: H01L31/0368
Filed: 1980-01-30
Abstract: The cell is formed in an Si wafer having a major surface adapted for impingement of light formed from randomly arranged, irregular, individual Si grains having mean dia. >=100 mu. (pref. >=1 mm) and grain boundaries that contact or are sepd. only slightly from adjacent grains at the impingement surface. A photovoltaic junction is formed extending across and below the surface and into the interior of the wafer along and inward of the grain boundaries, penetrating the wafer so that the total junction area exceeds the prod. of linear dimensions of the wafer surface but not so that the junction extends completely round the Si grain boundaries or to the opposite surface. The junction is formed by (a) diffusing impurity into the impingement surface and (b) maintaining in an atmos. free from the impurity at temp. and for a time causing the impurity to penetrate between grain boundaries and into individual grains. The cell gives satisfactory energy prodn., e.g. 15% conversion efficiency, at an efficiency/expense ratio much better than monocrystalline Si cells.

Patent NL-8802908-A (NL)
Title: Interface between a terminal server and an X.25 PAD
IPC: G06F3/12
Filed: 1988-11-25
Abstract: Under specific circumstances, print jobs which are sent by a computer system via a terminal server 3 and an X.25 network 6 to an asynchronous printer 8 may be lost. The loss of print jobs is the result of the fact that only the first status signal CTS originating from the X.25 PAD 5, indicating that the X.25 PAD is ready to receive data, is continuously monitored by a terminal server in terms of the flow control of the print job which is to be sent, but not the second status signal DSR, indicating that the link to the printer is ready. The invention provides for an interface 4 between the terminal server and the PAD 5, which, on the basis of the algorithm SS 1 [n] = (SS1[o] .AND. SS2), produces a new first status signal CTS[n] from the original first status signal CTS[o] and the second status signal DSR.

Title: Virus-contamination preventing syringe - has needle placed in clamped closed container attached to cylindrical part of syringe after use to prevent re-use
IPC: A61M5/24
Filed: 1989-01-27

The needles and the syringe are unsuitable for reuse once already used and an 'infected' syringe can not be reused. Others are not contaminated since they cannot be cut or injured on sharp contaminated projections. The needle is placed after use in a rigidly clamped closed container attached to the cylindrical point of the syringe. During insertion, atmospheric contact is caused between the chamber under the plunger and/or the pressure compartment of the syringe bounded by the cylindrical housing and the plunger.

Patent NL-9200723-A (NL)
Title: Homogenizer for homogenizing manure, fitted in an (existing) manure tank
IPC: B01F13/00
Filed: 1992-04-21
Abstract: The invention relates to a homogenizer (homogenizing apparatus) for homogenizing manure which is contaminated with straw, silage residues and/or other organic material. The homogenizer as a whole is fitted in a hollow tube. This hollow tube is fitted in the manure tank. At the front, the tube projects through the wall of the manure tank and runs through as far as the rear wall of the manure tank. At the front and back this hollow tube has holes through which the manure can be drawn in and be pushed back into the manure tank. The homogenizer consists of a ring which, by means of three bars, is divided into three openings. Positioned behind this ring is a sleeve. Two knives are mounted obliquely on this sleeve, the cutting edges of the knives being positioned so as to face the said holes. By means of a spring, the knives are pushed towards the ring, thus ensuring lasting efficacy. Fitted in front of the ring is an auger or conveyor screw which draws in the manure through the holes in the tube and then pushes it through the ring. Once the manure has passed this ring, it is cut into shorter pieces by the two knives and further homogenized. The homogeneous mass thus obtained can be processed by present-day manure injectors or sod injectors with the aid of this installation. As long as manure is present in the manure tank, the manure will be pumped round and be processed by the installation.

Title: Container-lid opener
IPC: B65F1/16
Filed: 1993-07-14
Abstract: Container-lid opener which can be operated by means of a foot and can easily be removed from the container. A lever provided with a semicircular guide can rotate about the axle of the container.

Filed: 1991-06-06
Abstract: Described is the use of oleophilic esters of ecologically compatible polycarboxylic acids with oil-soluble and ecologically compatible monofunctional alcohols and/or polyfunctional alcohols which may also be watersoluble as the oil phase or as a component of the oil phase of oil-based or water-based drilling fluids and other fluid drill-hole treatment agents. The oleophilic polycarboxylic acid esters are especially suitable as component of the continuous oil phase of inverted fluids of the W/O type. Here-if rheologically suitable compounds will be employed-they may comprise the at least predominant portion of the continuous oil phase; but also possible is the concomitant use of complex oleophilic polycarboxylic acid esters, which are not or just to a restricted degree fluid in a temperature range of from 0 DEG  C. to 20 DEG  C., as an additive in fluid oils of the class of the non-polluting oils. Here, suitable oil mixing phases especially are oleophilic alcohols, ethers, respective esters of monocarboxylic acids and fluid oils based on oleophilic carbonic acid diesters.
