Title: Method and apparatus for recovering caprolactam
IPC: C07D201/16
Filed: 1987-11-19
Granted: 1991-10-23
Abstract: Method and improved apparatus for recovering a volatile organic material, such as caprolactam, from a liquid mixture of organic and inorganic materials. The method features the step of mixing the liquid mixture with superheated steam for 0.005 to 1.0 second to vaporize a large portion of the volatile organic material without degrading the organic materials. The steam and vaporized organic materials are then separated from the liquid mixture remaining, followed by separation of the vaporized organic material from the steam. The vaporized organic material subsequently is condensed. The improved apparatus features means for introducing superheated steam into a vaporizer feed pipe, as well as means for mixing the superheated steam with the liquid mixture in the pipe for 0.005 to 1.0 second so that a large portion of the volatile organic material is vaporized and feeds with the steam and remaining liquid mixture into the vaporizer for separation.

Abstract: A digital compass (20) has a sensing coil (60) wound on an elongated strip of high direct current permeability magnetic material. The sensing coil (60) is connected to a sensing circuit (56). The sensing coil and sensing circuit are responsive to the Earth's magnetic field to provide an oscillating signal at an output (28) of the sensing circuit (56) which varies in frequency with orientation of the at least one sensing coil (60) with respect to the Earth's magnetic field. A microprocessor (36) is connected to receive information inputs from the oscillating signal. The microprocessor converts the information inputs to an indication of orientation of the sensing coil with respect to the Earth's magnetic field based on the frequency of the oscillating signal. A display (52) receives the orientation indication from the microprocessor.

Abstract: For recovering such a bit clock, a bit clock having the frequency of the signal to be received is generated at the receiving end by means of a clock generator (TG) and a counter (Z). The position in time of the rising edge of a received pulse is evaluated in comparison with a predetermined position in time of the effective pulse edge of the bit clock generated by means of a phase evaluating logic (PAL). In the case of synchronism, the effective pulse edge is located in the centre of the pulse received in each case, considered in terms of time (bit-centre sampling). Due to non-ideal line characteristics, the period of the received pulses can deviate from the normal value. To be able to distinguish an instantaneous edge drift of a received pulse (pulse too short or too long) from an actual phase shift, the position in time of the rising and of the falling edge of each pulse is now determined. 
<??>If too short or too long a pulse deviating from the normal period is present which, however, is symmetric with respect to the predetermined position in time of the effective pulse edge of the bit clock generated, this is an instantaneous edge drift so that no phase correction is required.

Abstract: During horizontal storage, the paper rolls (2) are supported along an outer-surface segment by a bearing face (10), the surface of which is matched to the peripheral surface (27). However, particularly in the case of softly wound paper rolls and long storage time, peripheral flattenings may result which, given the high speeds of rotation to which paper rolls are subjected during processing in the printing industry, may have a damaging effect on the work routine. In order to avoid permanent peripheral flattenings, the paper rolls (2) are in each case rotated by a specified angle of rotation after a specified storage time by a transport trolley (5) having two motor-driven rotatable support shafts (23), after which they are stored again in a different position of rotation.

Abstract: A flat ball point pen, comprising a cartridge holder part and clasp part, is foldable into a non-writing disposition, wherein one part is pivoted into the other and the two parts define top and bottom surfaces which are flush with each other. In the folded out, or writing disposition, the two parts are firmly connected and have virtually the same length as a standard ball point pen, the clasp part being configured to form a receiving framework for the cartridge holder part, in the form of a closed frame, having two arms joined together at one end and a strut connecting those two arms at the other end. The cartridge holder at its end opposite the writing nib includes a slotted locking member with two walls forming the slot to receive the above mentioned strut, the strut being enclosed between the two walls, with the free ends of the walls ending in facing grooves, which have cleats turned inward. Near the end of the framework, the arms have tongues to receive the grooves when the parts are moved in a relative sense together for locking them together.

Abstract: A dispensing closure having a base ring with means for attachment to a container which permits rotation of the ring without axial movement. A lid is connected to the base ring by a hinge which allows the lid to be swung from a closed position blocking access to a container opening to an open dispensing position. A cam element on the lid effects initial movement of the lid towards an open position when the base ring is rotated. The lid cam element cooperates with a cam surface on the container. A fitment can also be used to attach the closure to a flat can top or to other container configurations. When a fitment is used, the cam surface will be on the fitment rather than the container.

Abstract: The invention relates to aqueous solids suspensions which are stable to sedimentation and in particular milk of lime based on aqueous suspensions of calcium hydroxide Ca(OH)2, which contain, as sedimentation stabiliser, waterglass, preferably in an amount of 0.5 to 8% by weight, calculated as solid waterglass containing 17 to 20% by weight of water and based on the mass of the solid in the suspension, and processes for their preparation and their use and dry solids mixtures containing added stabilisers. In the case of the preparation of milk of lime, the waterglass may be added both before or during slaking of calcined lime and before or after calcium hydroxide is mixed into the preparation water. Suspensions stabilised according to the invention, such as milk of lime, are stable to sedimentation over a storage time of at least 5 weeks, even at low temperatures, not more than 5% of serum being formed. Even after a longer storage time without mechanical mixing, a corresponding milk of lime can be stirred up simply and rapidly for use. The invention accordingly has exceptional advantages in terms of process engineering and economics, since the investment costs for stirring or mixing apparatuses and mechanical mixing for stirring up are not required during the entire storage time. The invention leads in particular to high energy savings.
