Title: Resorcinol-filler preparation, process for producing  same and its use
Inventor: KUEHNER GERHARD

Granted: 1985-04-09
Abstract: ABSTRACT OF THE DISCLSOURE        The preparation according to the invention comprises resorcinol and at least one carbon black in homogeneous dis-tribution.  The preparation is preferably in the form of beads or granulates.  The preferred granular form is attained when the resorcinol has an average particle  size of 0.10 to 0.40 mm or is reduced to this average particle size during the pro-duction process.  Furnace blacks having a specific particle surface area of approximately 40 to 120 square metres per gram, an average primary particle size of 20 to 45 nm and a dibutyl phthalate absorption of 45 to 130 millilitres per 100 grams are preferred as carbon blacks.  The preparation according to the invention preferably has a weight ratio of carbon black to resorcin between 70 to 30 and 30 to 70.  The upper limit of this weight ratio is 95 to 5.  The process for producing the resorcin-filler preparation in which carbon black is put into a mixer capable of high-speed performance and provided with a heating device, and when required with a cooling device, as well as with a propeller-type or rough mixing tool, resorcinol is liquefied by heating, the liquid resorcinol is fed into the fast running, heated mixer in batches or continuously, the step for forming the preparation is thus initiated, continued and completed until beads are formed and the beads are cooled or allowed to cool in the running mixer until they are free from tackiness.

Abstract: NOISE MAKING BALLOON VALVE          ABSTRACT      A noise  making  valve  for  a  toy  balloon  includes  a  casing enclosing a moveable valve body and a resonant reed disposed upstream of the valve body.  A perforate membrane substantially closing the end of the casing opposite the balloon is depressable to lift the valve body from its seat, causing emission of a tone.  The valve body is positively enclosed in the casing,  and the reed is protected by folded-over tabs, such that no part of the valve is removable by the user.  Safety features also include an enlarged trumpet shape and a restriction preventing a complete sudden ejection of the valve from the balloon.

Abstract: Abstract The invention relates to a boom structure in an oil-spill-combatting system. The principle of the apparatus is as follows: from the water craft (2) there extends to each side a boom, and the ends of the collecting rope (4) are secured to the ends of the booms. The oil is recovered from the rope by running the rope (4) through an apparatus (3) which is situated at the aft of the craft (2). The rope is run first in one direction and then in the opposite direction. According to the invention the rope is put into effective use, up to the last meter, by making the booms from two sections (5, 6),of which the outer one (6) turns synchronically with the passage of the rope (4) and brings each rope end alternately next to the recovery apparatus (3).     Figure 1 has been selected for the abstract.

Abstract: DOUBLE ACTION CRIB DROP SIDE LOCK               ABSTRACT OF THE DISCLOSURE           A double action securing device for the drop side of a crib comprises a guide member connected to the crib or to the drop side in a vertically oriented position.  A slide member is slidably mounted to the guide member between two positions for raising and lowering the drop side.  A catch pin is axially and rotatably mounted to the slide member and engageable with an opening of the guide member in at least one of the relative positions.  The catch pin has a head which defines a recess for embracing a lower edge of the guide member opening.  The weight of the slide member causes the head recess to drop over the lower edge of the opening to lock the slide member with respecto the guide member.  The catch pin can further be rotated to increase the engagement.  A disengagement or unlocking of the slide member from the guide member thus requires at least two distinct movements, one for raising the catch pin and thus disengaging the head recess from the opening edge, and the other for axially withdrawing the catch pin head from the opening.  When the catch pin is rotatable, a third motion is required to initially align the head with the opening, and thereafter lift and axially withdraw the head.

Abstract: ABSTRACT          An acoustic logging apparatus and method are disclosed for determining the direction of a subsurface noise source, such as a blowout well or fluid channeling behind well casing.  The apparatus comprises cylindrical piezoelectric crystal transducers processed to buck each other.  The method employs such an apparatus and includes generating and observing output from the crystals.  The direction of the noise relative to the position of the apparatus is indicated by determining the position of the crystal transducers when their phase and amplitude differences are at a minimum.  The transducer leading in phase at a point perpendicular to said position is the transducer closest to the noise source and is used to indicate the absolute direction of the noise.

The vertically extending main body is made of a base cloth of which both longitudinally extending side edges are jointed to one another to build a tubular zigzag slip down passage.  A zigzag slip down passage cloth having a plurality of bent parts is fixedly secured to the base cloth.  An inclined slip way is jointed to the lower end of the main body so that the person who has desdended through the zigzag slip down passage lands on the platform by way of the inclined slip way.  An expansible cloth of which expansibility is deter-mined in the range of 200 to 250 % as seen in the longitu-dinal direction as well as in the peripheral direction of the main body is fixedly secured to each of the bent parts on the zigzag slip down passage cloth.  When dead weight of the descending person is exerted on the expansible cloth, the zigzag slip down passage is caused to expand whereby he descends through the zigzag slip down passage smoothly without any occurrence of stoppage at the bent parts on the zigzag slip down passage cloth.  Thus, he can land on the platform serving as a lifeboat quickly and safely.

Abstract: ABSTRACT OF THE DISCLOSURE             The crossbow has an elongated frame formed at one end with a stock containing a triggering mechanism including a trigger and a latch.  The other end of the crossbow is a barrel which includes a slide to mount an arrow.  A bow and string combination is disposed on the barrel at the front part thereof to be associated with the slide.  The cocking mechanism comprises a sliding channel formed in the barrel, whose rearward end extends to the triggering mechanism and is in open communication therewith.  A string engaging member is slidably disposed in the channel and has a hooking device thereon to engage the string.  The string engaging member is arranged to engage the string while the latter is in released posi-tion and to slide in the channel with the string hooked thereto until the latter is in cocked position and becomes engaged by the latch.  A spring or the like then retracts the string engaging member at the forward end of the channel.  This cocking mechanism requires less strength to operate than other known devices and is much easier and cheaper to manufacture.
