Inventor: KILGUS KARLHEINZ
IPC: B60P1/64
Filed: 1981-12-29
Abstract: The transport vehicle (10) having a chassis (11) with a changing device (30, 60, 80) and with an interchangeable body (20) which can be lowered thereon has lifting/lowering cylinder-piston assemblies (32) which are operated in a hydraulic lifting circuit and lower and lift the interchangeable body (20) with hydraulic setting-down pressure, and locking elements (52, 53) on the changing device (30, 60, 80) and on the interchangeable body (20) which lock the interchangeable body (20) to the changing device (30, 60, 80) when the interchangeable body (20) is displaced by locking travel, and at least one sliding cylinder-piston assembly (60) which is operated in a hydraulic sliding circuit, and a driver device (80) and a control valve (43). In order to simplify control, the hydraulic sliding circuit and the hydraulic lifting circuit are connected directly in parallel, specifically in such a way that on the one hand cylinder spaces for the lowering and locking movement and on the other hand cylinder spaces for the unlocking and the lifting movement are connected hydraulically and the respective piston face in the assemblies is selected in such a way that the fitting-on pressure is greater than the sliding pressure. The sliding cylinder-piston assembly (60) attached to the chassis (11) has on the sliding rod (81) a preferably plate-shaped sliding rod head (82). Pressure plates (100.2) are spaced from one another by at least the thickness of the sliding rod head (82) in addition to the thickness of a folding plate which is attached to the rear pressure plate (100.2) so as to be capable of folding away upwards.

Title: Treatment for the purification of a uranium-bearing concentrate
Inventor: JOUBERT PHILIPPE
IPC: C01G43/00
Filed: 1982-11-15
Abstract: Purification method of uraniferous concentrates containing impurities of which particularly at least one of zirconium and/or hafnium elements, comprising the treatment of said concentrates in an acidic and hot aqueous medium by means of hydrogen peroxyde to cause the formation of uranium peroxyde which is characterized in that in a first step, and in order to quantitatively precipitate the uranium and to solubilize all or part of the impurities, the uraniferous concentrate is suspended in the aqueous medium, and slowly and controllably said suspension is acidified by means of an acidic agent, the resulting acidified aqueous medium is treated by means of hydrogen peroxyde thereby causing the formation of a precipitate containing essentially the uranium and almost the totality of zirconium and/or hafnium that is separated from the liquid phase containing impurities, and in a second step the precipitate provided from the first step is treated by means of an acidic agent to cause the transformation and solubilization of the uranium into soluble uranyl ions and the liquid phase containing the uranyl ions is separated from the solid phase formed by a compound containing the zirconium and/or hafnium. According to an alternative, concerning the first step, the acidified aqueous medium is treated by means of a source of fluoride ions.

Title: Lathe rotating mechanism position determn. using resolvers - measures phase lag between input and output sinusoidal signals for simple and differential sensors
IPC: G08C19/46
Filed: 1982-01-15
Abstract: The device measures the position of a number of rotatable mechanisms which are set in motion successively such as occurs in a lathe. The measuring device (10) emits sine and cosine electrical signals which are applied via an electrical connection (16) to the input of a first differential pick-up (24) which is coupled to the first rotatable mechanism (4). The output signals of this first pick-up are applied by electrical connection to the input of a second differential pick-up coupled to the second rotatable mechanism and so on in succession to the last rotating mechanism (5). This last mechanism is coupled to a simple pick-up (15) to whose input are applied the sine and cosine signals of the output of the differential pick-up integral with the last but one rotable mechanism. The output sinusoidal electrical signal from the simple pick-up is applied via an electrical connection (17) to the measuring device (10). The phase-lag between the sinusoidal signal applied to the first differential pick-up and the sinusoidal signal received from the simple pick-up is measured, this being related to the angle of rotation of the rotatable mechanisms w.r.t. a fixed reference position.

Patent FR-2506445-A1 (FR)
Inventor: SIEBECKER HANS
IPC: G01S17/86
Filed: 1982-05-14
Abstract: The method for warning against enemy laser radiation (16, 16') and the device for this purpose are used for protecting friendly (one's own) weapon systems which are fitted with a warning sensor arrangement (17). This arrangement is integrated with a laser receiver (8) which is located on the optical axis (14) of the sight and, together therewith, forms a common input objective lens (9). Arranged in front of the receiver diode (11) is a perforated aperture (10) having a central aperture opening (15) which is surrounded on its side facing the incident radiation by the sensor arrangement so that external radiation (16, 16') which is incident from any angle, or radiation (13) which has previously been emitted by one's own laser transmitter and has been reflected by the target is recorded (detected). The device needs to be aligned only coarsely for this purpose in order to be able to react "with lightning speed" in the event of (visible or invisible) illumination, resulting from an enemy attack, by precisely aiming the weapon system and subsequently carrying out one's own laser range measurement (laser rangefinding), marking the most threatening enemy, firing ammunition or producing radiation which is hazardous to enemy gunners.

Title: Self-controlled and self protected alarm device
Inventor: FAGET JEAN
IPC: G08B29/04
Filed: 1983-09-29
Abstract: The invention relates to an electronic self-controlled alarm device. Set off conditions of the alarm are periodically established by varying alternatively into plus and into minus the resistance of the detection loop wherein are arranged detectors comprising a resistance in series with contacts. A self protection capacitive loop controls a square signal generator which produces: a) short pulses having the frequency f (self-protection), b) rectangular signals having the frequency 2f (self-control), verified at the terminals of the time delayed alarm relay. The cut-off or the shorting of a detector or of the detection loop sets off the alarm. The absence of self protection pulses or an incorrect frequency of the self-control signals sets off a fault warning device. The invention applies to alarm, surveyance, control, measurement apparatus and installations used for the protection against burglary and fire, in the industry, for the medical surveyance, etc.

Title: Educational electronic game
IPC: G09B7/02
Filed: 1983-04-21
Abstract: The subject of the present invention is an educational electronic game based on the question/answer principle. This game consists in recording in a microprocessor memory particulars relating to the French départements (préfectures, sub-préfectures, number of inhabitants, area, etc.) and in retrieving them on a display screen, after interrogating the device with the aid of a digital keypad into which is tapped the number of the département. The answer to the question posed starts with the appearance of the outline of a map of France on the screen, with a drawing of the chosen département, located by the flashing of its outline. Next there appear the geographical particulars relating to the département. As a variant, geographical data relating to the principal countries (Belgium, Switzerland, etc.) can be added to the device of the invention through an alphabetic keypad.
