Patent NL-300533-A (NL)
IPC: B01J25/02
Abstract: Unsymmetrical dialkylhybrazines are prepared by the reduction of dialkylnitrosamines in the liquid phase with hydrogen at a hydrogen pressure of below 50 atmospheres gauge and at a temperature between - 20 DEG  C. and +50 DEG  C. in a reaction medium rendered alkaline by the addition of an alkali metal hydroxide in sufficient quantityto give the medium a content of 0.001 to 5.0 moles of dissolved hydroxide per dm.3 of reaction medium or made ionic by adding thereto soluble metallic salts or alkaline earth metal hydroxide in a quantity of 0.001 to 5.0 moles of dissolved electrolyte per dm.3 of reaction medium, the reduction being effected in the presence of Raney nickel catalyst obtained by an attack of an aqueos solution of caustic alkali on a Ni-Al alloy or alloys, the ratio by weight of catalyst to dialkylnitrosamine being between 0.001 and 1.0 and the ratio by weight of catalyst to reaction medium being between 0.001 and 0.50.  The catalyst may be dehydrogenated before use and if stored may be dipped into aqueous alkali metal hydroxide first prior to use.ALSO:Raney-Nickel catalyst is obtained by heating a Ni-Al alloy or alloys, preferably those which pass a sieve No. 26 AFNOR, at about 100 DEG C. with a 250 g/litre solution of sodium hydroxide in such quantity that the weight of dissolved sodium hydroxide is equal to the weight of alloys used, decanting, again treating the alloy or alloys with sodium hydroxide under identical conditions to the first treatment, discarding the sodium hydroxide solution and washing the alloy or alloys with water.  The catalyst so obtained may be dehydrogenated by contacting the catalyst metal with an anode resistant to alkaline electrolyte and traversing the catalyst metal with an electric current of below 500 milli amperes/cm2 (see Patent No. 1,010,187) or by immersing the catalyst in an electrolytic cell and traversing it by an electric current without it being in contact with either of the electrodes (see Patent No. 1,007,174).  Preferred Ni-Al alloys have the composition 40-55% by weight Ni; 60-38% Al, 0-1% Cu and 0-6% Fe and a specially preferred alloy has the composition 47.5% by weight Ni, 49% Al, 0.5% Cu and 3% Fe.  Catalysts which have been stored may be dipped into aqueous alkali metal hydroxide just prior to use.

Title: Underwater paint applicator - using compressed air water excluder combined with spray
IPC: B05B17/00
Filed: 1971-09-01
Abstract: An elongated narrow nozzle with a system of support rollers and held against the surface to be painted, esp. ship's hull plating, by esp. electromagnetic means, is moved over that surface in a direction at right angles to the long dimension leaving a gap between its rim and the plating, at least along its trailing edge.

Title: Corona discharge surface treatment of sheet material - esp. of plastic material, using at least one cooled and insulation coated electrode
IPC: H01T19/00
Filed: 1978-05-31
Abstract: Sheet material is treated by passing it between a pair of corona discharge electrodes one of which is coated with an insulation material and has a cooling fluid flowing through it. Used esp. for corona discharge treatment of plastics film to improve the surface adhesion characteristics. For high prodn. rate the discharge density has to be high, which increases the heat generated in the electrode, and the heat can cause deterioration of the electrode insulation. Cooling of the electrode removes the heat, preserving the electrode.

Patent NL-8005692-A (NL)
Title: Burglar alarm system - detects position of intruder within guarded area by transmitting detector signals to central station
IPC: G01V1/00
Filed: 1980-10-15
Abstract: Conventional intruder alarm systems, which depend on a single vibration detector set in the middle of the area to be guarded, cannot detect the position of an intruder within the area, or detect a second or subsequent intruder after the first has been detected. Also, if the area to be guarded is not circular, the detector may detect people outside the required area. The system uses four detectors (D1 to D4) guarding an area (1) of about 1 hectare within a perimeter (2). The signals from the detectors are taken to a central station (S), where the phase differences between the detector outputs are used by an electronic calculator to produce the X and Y coordinates of the intruder/s within 100cm. These positions can be displayed on a video screen, X/Y plotter, etc.

There can be an external bush (21) on each nozzle (2), engaging at the rear with the rear wall of the casing (1).
Patent NL-8902846-A (NL)
IPC: G06V30/10
Filed: 1989-11-17
Abstract: The invention comprises a buffer system and a buffer (20) applied in it. The buffer acts as mechanical RAM and contains a number of storage pockets (28) for the temporary separate storage of flat articles such as letters for postal processing purposes such as, for example, sorting and video coding. Electromechanically the buffer is such that the letters are not released at any point and are subject to shifting as little as possible, and permit a dense packing of the pockets. This is achieved by using a slide/entrainment conveyance system which is formed by elastic clamping between an endless conveyor (54, 72, 77) with a very high coefficient of friction, for example one or more elastic cords running in parallel and a sliding surface (60, 73, 75) having a very low coefficient of friction both in the sections (21 and 22) of conveyance past the pockets and in the pockets (28). In the pockets, said sliding/entrainment conveyance system is constructed as a separately controllable letter catchment, retainment and ejection device. Each two successive buffer pockets have a partition in common provided with the endless conveyor (54) of one of the said two pockets and the sliding surface (60) of the other of the said two pockets. The buffer system comprises a number of such buffers (20) with or without distributed control. The buffers (20) are situated along a branching feed section (1, 23) in which a gate (20, 26) is sited at every buffer branching point and every connecting point. First process signal connections (6) via which so-called letter logging signals (BBS) are concomitantly transmitted for every letter conveyed along the feed section (1, 23) run in parallel with the branched feed section. Appended to each of said gates (25, 26) is a gate control (91, 38) which determines on the basis of the letter logging signals (BBS) and, for example, the number of free pockets (#-VAKKEN) in each of two gate directions in which direction the letter with its associated letter logging signals (BBS) is sent. Said letter logging signals comprise in all cases a letter identification code (BIC) assigned to the letter by an application control (5) when the letter is fed into the system. The application control continuously makes a selection of letters, which are eligible for discharge from the system, from the instantaneously stored letters on the basis of certain letter features which are derived from the letters to be fed in at the system entrance. Data of the selected letters, including time indications (TI) of when the letters have to pass a defined ejection point (X) in the system exit are transmitted via second process signal connections (9) to the control (38) of each of the buffers (20). Such a buffer system can readily be equipped either as a sorting system or as a video coding system.

Title: Method for electronically storing radiation images
IPC: H04N7/46
Filed: 1993-11-04
Abstract: Method for electronically storing radiation images, in which a radiation image is projected onto a radiation- sensitive sensor which optionally carries a pattern of radiation-sensitive cells distributed over its surface. Said sensor emits an analog or digital signal which is representative for said radiation image, said signal, if it is an analog signal, being digitized. Care is taken to ensure that the digital signal or the signal obtained by means of digitization, optionally with an intervening signal translation step, is representative of an electronic image composed of alternating positive and negative parallel lines which are to be projected so as to be substantially equally spaced and are each divided into a multiplicity of positions whose radiation value has been determined separately. Said signal for said electronic image is processed to produce a storage signal which is stored in a memory, said storage signal being determined by means of the following steps in succession.
