Patent EP-0038027-A1 (EP)
Inventor: WEVELSIEP KLAUS DR
IPC: G06V30/10

Abstract: The invention relates to a method and apparatus for identifying objects (e.g. consumer products in a supermarket) appearing in random positions and orientations and for random times on an image window and having an identification on the surface facing the image window in the form of a data field having contrasting indicia in at least one data track. The data field is first scanned with a scanning raster until a product identification code is recognized denoting the position and orientation of the data track. The data track is then read with a closely-spaced reading raster and converted to a videosignal. The amplitude of the videosignal is coded into binary digits at discrete time points and the digits are stored in a memory matrix organized into columns and rows in such a manner that an image of the data track is stored in the memory. Mutually overlapping partial regions of the memory are then read out in a pre-arranged sequence and fed to a decoder capable of accepting and decoding the information in this form. In this way, the information is converted from a row-by-row sequence produced by the reading raster into a succession of digits corresponding to individual partial regions of the data track for the recognition of individual symbols appearing therein.

Abstract: A throttle opener for a carburettor has a diaphragm device which has it's housing partitioned into a vacuum chamber (26) and an atmospheric chamber (27), by means of a diaphragm member (25). The vacuum chamber (26) is made to have communication through a communication passage (30), with an intake passage (7), just upstream of a throttle valve (17). A rocker arm (34), which has it's one end connected to the afore-mentioned diaphragm member is positioned to have it's other end in front of a connecting member (31), which is connected to said throttle valve. By means of the inventive throttle opener, it is possible to prevent the tendency of enriching an air-fuel mixture at the initial stage of the deceleration and to eliminate any reduction in the braking effect upon the engine.

Abstract: The specification describes a flyback power supply with secondary circuit damping during primary charging. This reduces the induced or reflected oscillations into the primary circuit and superimposition onto the primary current so that the latter becomes a monotonically increasing function, permitting and facilitating feedback control. 
     The power transistor 14 is connected in series with the primary winding of a flyback transformer. The transistor 14 is alternately switched on and off by a drive circuit 15 which receives a feedback signal from the output circuit. This circuit comprises the secondary winding, diode D1, and capacitor C1 supplying the load and has the parasitic stray capacitance Cs. The damping circuit comprising resistor Rd and diode Sd damps oscillatory currents during the charging cycle.

Abstract: The synthesis gas plant is operated in n successive periods. During the first period, fresh water in excess is supplied to the synthesis gas plant (1) and the waste water from the resulting mixture is separated in a condenser (8) and supplied to a storage container (25). During the next (n-1) operating periods the waste water stored in the container (25) is used as freed water for the synthesis gas plant (1) and the waste water obtained on each occasion is stored in layers, depending on its deuterium concentration, in the container (25). The waste water having the highest deuterium concentration, obtained during the last operating period, is introduced into a second container (24) and supplied therefrom to a heavy-water plant. In order to recover deuterium from the gas mixture leaving the condenser (8) and consisting of hydrogen, steam and residual components, the gas mixture is introduced into an exchange stage (38), in which the gas mixture is brought into isotope exchange in counter-current with additional water, as a result of which the additional water becomes enriched in deuterium and is supplied to the synthesis gas plant.

Abstract: Priority scheduling apparatus which allows for aging of the scheduled elements, so that an element of low priority will be assured of eventually receiving service. 
     The elements are enqueued into, and dequeued from, a table divided into ranks. Each element is enqueued at a rank given by I = B + N + P, where B is the rank from which the last dequeue occurred, N is the number of ranks of the table containing at least one element, and P is the priority level assigned to the element being enqueued. When elements are dequeued from the table they are always dequeued from the highest occupied rank. 
     The apparatus includes a control block storing the starting address of the table, and the values of B and N. The control block also stores a bit map having one bit for each rank in the table which is set to one when that rank is occupied by one or more elements and reset to zero when the rank is empty. The bit map is scanned to determine the highest occupied rank, and so determine the level from which a dequeue must take place. This value is stored to furnish the value of B for subsequent enqueuing operations.

Abstract: A novel three-dimensional radiation fringe velocimeter subsystem and a subsystem for determining air density related parameters, are combined into a single optical system (20) which permits various important parameters associated with the operation of an aircraft to be measured at a sample location at a sufficient distance from the aircraft (or any physical attachment thereto) so that the measurements will not be subject to systemic errors such as those caused by air compression effects and airflow disturbances, and which does not require that any Pitottubes, pressure ports or other similar mechanical devices protrude into the airstream where the measurements are to be made. The combined system (20) contains a laser (32) or other suitable source of radiation (14) as well as an optical arrangement (36, 38, 40) for transmitting the radiation from the laser (32) to a sample volume (12) in order both to form linearly independent sets of radiation fringes at the sample location as well as to focus the radiation (14) at the sample location so as to cause selected air molecules to fluoresce. The device also contains an optical receiving arrangement (40) for focusing backscattered radiation and fluorescent emissions from the sample volume onto one or more photodetectors (42). By using a radiation source (such as a Q-switched laser) that can be quickly switched between an On state and Off state it is possible to utilize a single photodetector (42), since the backscattered radiation will cease as soon as the radiation is turned off, but the fluorescent emissions will decay exponentially.

Abstract: Un fourrage pour animaux de haute qualité est produit par déshydratation thermique d'une purée liquide obtenue de la fermentation d'une matière première de céréales et de la distillation du produit de fermentation. La purée liquide est mélangée avec des particules d'un produit déjà déshydraté et le mélange est granulé dans un dispositif de granulation pour former des granules essentiellement sphériques présentant une teneur en substances sèches égale à 50-70 % en poids, la plupart des granules possédant un diamètre de particule de l'ordre de 2-6 millimètres, et les granules sont ensuite séchés en les faisant circuler en tant que lit poreux dans un chemin de commande en contact avec du gaz chaud à une température inférieure à 100oC, après quoi une partie des granules séchés présentant une dimension de particule désirée est déchargée et la partie restante des granules après désintégration éventuelle est renvoyée à l'étape de granulation. Etant donné que toute la déshydratation est exécutée par séchage au moyen d'un gaz à basse température, de la chaleur perdue ou de faibles valeurs thermiques telles que la chaleur de condensation dégagée par les condenseurs à refroidissement d'air (22) dans l'installation de distillation peut être utilisé pour le séchage des granules.
