Abstract: The invention relates to a method of measuring the concentration of radon and radon daughters in the ground, particularly at great depth and/or below the ground-water level. In accordance with the invention a detector is freely suspended from a wire and placed in a container intended for collecting gas rising up from the ground. The container is buried at a desired depth beneath the surface of the ground and the detector is exposed to the gas in the container over a given period of time. Subsequent to this exposure period, the detector is drawn up by means of the wire, together with a sleeve, protecting the detector from contact with surrounding ground, through the roof of the container and up through the ground, to a location so selected that the registered contents of radon and radon daughters can then be determined on the basis of the data registered on the detector. The invention also relates to preferred apparatus for carrying out the method.

Abstract: The method of identifying data supports such as credit cards, cheque cards, identity cards, etc. includes detecting inherent individual features of the cards to derive a random information therefrom. The random information is stored for later comparison with detected information to determine authenticity of the data support. In order to derive the random information in perfectly reproducible manner irrespective of changes of the dimensions of the data support, the individual characterizing features of the data supports are detected within a linear detection zone lying centrally between two opposed lateral edges of the data support. The invention provides an apparatus for perfectly aligning the data supports so that their central lines will always be coincident with the reading path of a detection system in which the data supports are processed.

Abstract: The method, which the inventor calls reverse ritual therapy, is using computermade reverse (anti) rituals (like playing a film backwards) of the rituals which observation of and participation in create dependency behaviour, as for example smoking, alcohol drinking, using of narcotics, etc (which are like playing the film forwards). The hypothesis is that the hypnosis of the computer reverse rituals will neutralize and eliminate the hypnosis of the dependency creating rituals. Since the human brain, when its lust center is activated, produces human own narcotic, as for example the morphine like endorphines, and since the video computer games (TV-games) cause game lust, the inventor expects that video computer game lust will cause brain's own production of narcotics and in this way, by using of video computer games he wants to create Pavlov reflex between the brain's own narcotics production and lust and the pictures of rejection of the missuse (for example of narcotics) so that every time when the player performs for example a ritual of rejection of narcotics his own brain's lust center will start to produce narcotics and will reward him with lust and pleasure instead of punishment and efforts which most of the other methods suggest and which in most cases the missuser is not capable of. The hypothesis is that the invention will use the body's own lust and pleasure against the destructive lust and pleasure from outside. One strong force from outside will meet an equal strong anti and complementing force from inside.

Abstract: The present invention seeks to provide a method in which the soda lye obtained as a result of cellulose cooking process and unslaked lime are used for producing white liquor which can be re-used in the cooking process. In this method, the heat released by the slaking of lime with soda lye is recovered by a high pressure slaking process wherein the heat is transferred, either to the steam separating from the lye, which steam is then led to the desired application, or to some other medium to be heated. The present invention is characterized in that the soda lye to be causticized is divided into two parts, one of which is used for the slaking of lime by adding to it all the unslaked lime needed for the causticizing process, and that, following slaking, the two volumes are brought together for the actual causticizing reaction involving the total amount of lye needed. The present invention provides the advantage that the amount of lye needed is smaller, and so the temperature can be increased.

Abstract: A process for the production of silicon in a low-shaft electric furnace, in which raw-material blanks are first formed which contain fine-grain silicon dioxide, e.g. in the form of sand, and carbon in excess in respect of the reduction to silicon carbide and the raw-material blanks are introduced into the low-shaft furnance as a charge in mixture with silicon dioxide in lump form. The silicon dioxide in the raw-material moldings is reduced to silicon carbide in an upper part of the low-shaft electric furnace at a temperature of below 1600 DEG  C. and coke structure agglomerates are formed from the excess carbon of the raw-material moldings. In a lower part of the low-shaft electric furnace, the silicon dioxide in lump form, is reduced to silicon with silicon carbide and carbon from the coke structure agglomerates at a temperature of above 1600 DEG  C., preferably from 1800 DEG  to 200 DEG  C. The raw-material moldings are formed with bituminous binder containing a fine-particle silica powder. The silicon carbon reduction results in coke structure agglomerates having a very large internal carbon area in accordance with the internal area and percentage proportion of silica powder in the raw-material moldings. The silicon dioxide and gaseous silicon monoxide are reduced with the coke structure agglomerates having the increased internal area.

Abstract: Oscillating and alternatively locking apparatus and method of determining the mass of an article by the shift of the period of oscillation of a flexibly mounted platform. An article whose mass is to be determined is placed upon the platform. The platform is caused to oscillate and the period of harmonic motion is calibrated. This period is compared against the period of harmonic motion when there is no article upon the platform, and the difference, or shift, in frequency, allows a determination of the mass of the article. A reversible motor is used to provide drive to a conveyor for transporting mail pieces onto the tray and for causing oscillation of the tray for purposes of weighing.

Title: Emergency stop for lathe - involves unit coupled to regulating bar and reacting to control signal
Inventor: JOHANSSON LENNART
IPC: B23B25/00
Filed: 1989-04-10
Abstract: A control signal causes the unit to activate the regulating bar (4), causing it to turn to the position in which free coupling and braking of the spindle/chuck occur. The signal comes from an actuator separate from the operating lever, and can take the form of a cord (9). The cord activates a valve which connects an air pressure to a cylinder (10), which in turn causes the regulating to be turned via components (14,16,19) on it. Such components transform the cylinder longitudinal displacement to a rotary movement for the regulating bar.
