Patent DE-2952247-A1 (DE)
Title: Personal checking of exposure to radiations - by appts. producing alarm when allowed dose has been reached and advising user when period arranged for surveillance has elapsed
Inventor: ENGDAHL JEAN
IPC: G01T1/02
Filed: 1979-12-24
Abstract: An appts. for personal checking of exposure to radiations, partic. X, beta and gamma, as well as to neutron flow or to cosmic radiations, comprises in combination a device sensitive to the irradiation, capable of producing an alarm when a dose, fixed in advance, has been reached or exceeded, and a device measuring time advising the user when the period arranged for the surveillance has elapsed, by a signal different from that produced when the allowed irradiation dose has been reached. The appts. takes account of the duration of exposure and indicates the time when the detector should be regenerated or changed. If, e.g. the allowed dose is 5 rems per year, the detector will be regulated to provide an alarm if the dose of 5 rems has been reached, while the time measuring device will indicate after a year that the limit dose has not been exceeded but that the sensitive element should be recharged, regenerated, measured or changed, according to its nature. The indications are such that there is no confusion between the alarm produced by an excessive dose and the advice that the checking period has ended.

Title: Petroleum thermo-mining system - involves injecting heating agent through holes into bed middle portion and extracting petroleum from holes in upper and lower parts
Inventor: BOXERMAN ARKADIJ ANATOLJEVIC
IPC: E21C41/24
Filed: 1980-01-07
Abstract: Set of underground mine workings is created and >=1 pref. three, galleries, drilling injection and mining holes formed. A heat transfer agent is introduced through these holes into the petroleum bed to heat it to a temp. at which the petroleum acquires the necessary fluidity. The heat transfer agent is introduced in the injection holes for its regular distribution over the whole vol. of the petroleum bed and for the expulsion of the petroleum through the mining holes to the working gallery, from which the petroleum is brought to the surface. The mining holes are drilled in the upper and lower parts of the petroleum bed. The injection holes are drilled into the middle part of the petroleum bed. Heat transfer agent is afterwards introduced with force into the middle part of the petroleum bed through the injection holes and the petroleum is recovered from the upper and lower parts of the petroleum bed through the mining holes. Recovery of petroleum is improved because of the heating of the petroleum and its redn. in viscosity, its expansion and the increase in press. in the bed. The heating efficiency is high and productivity is increased by the increase in the frequencies of mining in the petroleum strata and the suspension of the vol. of mine workings in sterile rocks, not satd. with petroleum.

Title: Facsimile picture transmission pulse height enhancement - using two delay and difference summation procedures to shape output signal
Inventor: WISCHER HERMANN
IPC: H04N1/403
Filed: 1980-07-01
Abstract: Pulse amplification and contrast increase method for picture signals distorted during a facsimile transmission. Before transmission the video signal (UA) is twice delayed in a parallel circuit so that two difference signals so produced can be added to the non-delayed signal in order to improve picture quality and minimise loss of detail. The original (1) is scanned under light sources (2,3) by an opto electronic unit (5), e.g. a Fairchild Type 122 CCD, which produces the video signal (UA). The video passes through two delay stages (16,17) with the undelayed and once delayed outputs being presented to comparators (21,22) so that the three delay states can be summated (23) as original and difference signals (UA,UD1,UD2) before being frequency modulated (14) and transmitted to line.

Title: Suspension for vehicles
Inventor: TIMINSZKY JOSEF DIPL ING
IPC: B60G11/42
Filed: 1981-02-14
Abstract: The device is a progressively acting suspension for vehicles, in particular for motor vehicles, in which the spring hardness of leaf spring piles is automatically matched to the respective load. A leaf spring pile (Fig. 1) consists here of at least one guide leaf which is mounted on the frame of the vehicle and at least one spring leaf which is arranged underneath the latter, is greater in width and, in the case of relatively high loading, comes to rest with its protruding edge strips on rolling faces in order to shorten the effective spring length whilst the guide leaf can continue to experience spring travel. The relief from load, thus achieved, of the guide leaf, which is particularly at risk, makes possible a lightweight design of the suspension accompanied by a high degree of safety. <IMAGE>
Patent DE-3105581-A1 (DE)
Inventor: MOEBUS OTTO DR
IPC: C12P7/06
Filed: 1981-02-16
Abstract: Residue-free production of ethanol and unicellular protein in a gas-fluidized bed, in which ethanol production takes place in a gas-fluidized bed (stirred fluidized bed, fluid column), the particle fraction of which consists of a wet microorganism mass, e.g. Saccharomyces cerevisiae. A nutrient solution with fermentable carbohydrates is sprayed onto the fluidized particles. The ethanol, which evaporates with the water, is precipitated in a condenser on the discharge side, so that the fluidized bed serves as bio-reactor as well as one-stage distillation plant (together with the cooling system). Thus, the mash column, which is normally used for alcohol production with the submersion method, is not needed in the present invention. In place of the residue, a protein-rich product with 30-40% dry mass is formed, which, during continuous operation, can be removed at certain intervals from the bioreactor and can be dried to the desired degree. The propagation of the microorganisms can be regulated through the oxygen content of the gas phase; the ethanol production can be regulated through the infeed of the nutrient solution. The gas used for fluidization is recirculated into the bed. The partial oxygen pressure can be controlled by adding other gases to the air, such as nitrogen or carbon dioxide, particularly carbon dioxide, which forms the yeast itself.

Title: Variable room divider for interior finishing work, consisting of standards and partitions
Inventor: STENEMANN BRUNO
IPC: E04B2/78
Filed: 1981-10-02
Abstract: In a variable room divider for interior finishing work, use is made on the one hand of vertical standards having, over their periphery, a ring of longitudinally extending webs of T-shaped profile, between which longitudinally extending undercut grooves are formed. Also included are partitions which are each arranged between two standards and are connected, via connection members, at given profile heights of the standard, as desired. To develop a simple, inexpensive room divider which offers a wide variety of connection possibilities for partitions as well as an economical design of the standard profile, it is proposed to form the connection member from a clamping shoe which can be reversibly coupled to the standard and has mutually contrasting coupling ends which are designed, at one end, as male mould-shaped coupling faces and, at the other end, as female mould-shaped coupling faces, which can grip a web or a groove of the standard, as desired. The clamping shoe is penetrated by a threaded bore for a cap screw which can be screwed therein and the shank end of which can then be supported in each case at a selected profile point of the standard. The cap end, here pointing in each case radially outwards, of the screw serves to suspend a slot located at the front end of the partition. <IMAGE>

Title: Droppable body in the form of a mine for combatting ground targets
Inventor: SCHMIDT ROLAND ING GRAD
IPC: F42B10/26
Filed: 1981-12-05
Abstract: The invention relates to a droppable body in the form of a mine for combatting ground targets, which is dropped from a carrier aircraft or from an ammunition container of a carrier aircraft. The mine, after being dropped, is set in rapid rotation, for example by means of air scoops (4). The mine is moreover so designed that, after impact with the ground, this rotational energy is converted at least partially into a translational movement. As a result of the design of the mine, the latter follows an irregular path (11) on the ground until it comes to a stop. The effective combat area of such a droppable mine can thereby be increased. To obtain this irregular path, the mine is equipped, for example on its circumference, with helical springs (6) coordinated with the weight of the mine. The mine can also have a design in the form of a cube, cylinder or ellipsoid. <IMAGE>

Title: Arrangement for recording and scanning electric audio frequency signals representing sound events onto and from a sound carrier
Inventor: KLAUSE GERHARD DR ING
IPC: H03G7/00
Filed: 1982-02-03
Abstract: The invention relates to an arrangement for recording and scanning audio frequency signals representing sound events onto and from a sound carrier by analog technology using companding. In order to achieve an improved quality of reproduction at the same time as complete compatibility of sound carrier, recording apparatus and reproducing apparatus with simple equipment, the invention envisages that, in the compressor, the audio frequency signal or the output signal of the control signal generator to be recorded is additionally fed to a pilot-control signal converter which emits at least one inaudible pilot-control signal which is separate from the audio frequency signal to be recorded and is(are) a clear measure of the compression which has taken place in the compressor corresponding to the level of the audio frequency signal, that the pilot-control signal(s) is(are) recorded together with the compressed audio frequency signal on the sound carrier and that, in the expander, the pilot-control signal(s) scanned together with the compressed audio frequency signal is(are) coupled out and used for controlling the control signal converter of the expander and deriving the expanded audio frequency signal.

Title: Test apparatus for portable firearms
Inventor: SCHUESSLER EUGEN
IPC: F41A23/16
Filed: 1982-02-06
Abstract: A rigid frame (2) is mounted pivotably in its rear part in a baseplate (13) by means of a pivot pin (6). The front part of the frame (2) contains an upwardly open firearm rest (3) and possesses, furthermore, two bearing points (5) which are displaceable on the baseplate (13) in an arc of a circle about the pivot pin (6). In the rear part of the frame (2) there is a receiving device (1) for the stock (10a) of a firearm (10). This stock receptacle surrounds the stock (10a) and contains a pressure cuff (8) which, when pressure (for example compressed air) is supplied, lays itself firmly round the stock (10a), but remains to some extent elastically deformable on all sides. As a result of the clamping effect of the gripping pressure cuff (8) on the one hand, and its elastic deformability, on the other hand, when a shot is fired the recoil and also the shift of the front part of the firearm upwards and sideways are absorbed elastically. With the test apparatus, virtually life-like conditions, despite a clamping of the firearm, are provided. <IMAGE>

Title: Circuit arrangement for speed control of a hand-held machine tool
Inventor: KRESS WILLY
IPC: H02P27/02
Filed: 1982-04-20
Abstract: The invention relates to a circuit arrangement by means of which the speed of a hand-held machine tool which is driven by an electric motor is kept at a low standby speed on no load, at which speed the amount of noise produced is greatly reduced. When the hand-held machine tool is loaded, the speed automatically rises to the higher operating speed which is required. The speed changeover is controlled electronically by a current sensor which detects the higher current consumption of the electric motor when it is under load. A timer keeps the electric motor at the higher operating speed for a certain run-on time after completion of the operating process.
