Abstract: Apparatus for introducing cigarette groups into cigarette packs Abstract: (In conjunction with Figure 5) In the production of (cigarette)packs, especially in the design as hinge-lid packs, the introduction of a group of cigarettes (cigarette block) into the partial-ly folded pack presents a special problem because of the high productive capacity of the packaging machines and the high transport speeds necessary as a result.     In the present case, the cigarette block  is  fed  in the   radial   direction   to   a   folding   turret for the pack, the cigarette block being received in a block pocket during a transport stage.     To prevent relative displacements in this, the cigarette block is fixed, during transport in the block pocket, by clamping

Abstract: STRESS RELIEVING NUT MEMBER            Abstract A nut member and composite joint configuration designed to elimi-nate compressive stress on work panels that are fragile. A nut with a tubular section and a flange, which is spaced both radially and axially from one extremity of the tube and provided with an adhesive surface, may be inserted from one side of the fragile panel so that the end of the tubular section is spaced within the aperture in the fragile panel. Compressive clamping forces applied by a male member draws the end up into abut-ment with the overlying panel while the adhesive absorbs much of the stress in the joint.

Abstract: ABSTRACT OF THE DISCLOSURE A method for preparing a pulverulent mixture of amphi-philic lipidic constituents and possibly for hydrophobic con-stituents, and a method for producing hydrated lipidic lamellar phases from the said pulverulent mixture. The amphiphilic lipidic constituents and the hydrophobic constituents are dis-solved in a non-aqueous solvent and the solution is then atomized in a flow of gaseous fluid to produce the pulverulent mixture. The mixture is a homogeneous and very fine powder which can be very easily dispersed in a suitable aqueous dispersion medium to produce either slightly hydrated lipidic lamellar phases or highly hydrated lipidic lamellar phases such as liposomes useful in the pharmaceutical and cosmetic fields.

Abstract: ABSTRACT OF THE DISCLOSURE  A temperature-compensated magnetoelastic force trans-ducer is produced by mutually exciting a measuring trans-ducer  and  a  reference  transducer having cores  of  the same material  and  the same design and in good thermal contact.  A spring loads the core of the reference trans-ducer with a constant force.   The output signal of the reference  transducer is  rectified  in a  phase-sensitive rectifier,  the output signal of which is compared with a  constant  reference  voltage.    The  difference  signal resulting from this comparison controls the phase position of the control voltage of the rectifier in such a way that the output signal of the rectifier is brought into agreement with the reference voltage.  The output signal of the measuring transducer is also rectified in a phase-sensitive rectifier, which is controlled by said control voltage and the output signal of which constitutes the temperature-compensated measured signal.

Ranitidine is a valuable medicine in the treatment of ulcer diseases.  Owing to a very simple course of the reaction and an extrodinary short reaction time, the process is excellently suitable for the industrial scale production.

Abstract: HIGH YIELD PROCESS FOR IN VITRO  PRODUCTION OF SERUM-FREE AND     ABSTRACT OF THE DISCLOSURE   An improved in vitro cell culture process for producing in high yield and purity a serum-free and mitogen-free interleukin-2-containing conditioned supernatant.  The incubation steps during stimulation and conditioning of the interleukin-2 producing cells is carried out with a rapidly rotating roller bottle culture system.  Yields of interleukin-2 are on the order of 10-fold and higher than obtained by similar cultivations carried out in flat dishes or tubes or in a roller bottle culture system rotated at conventional speeds.  Improvement in yields in both the static and roller culture systems are also achieved by incubating the IL-2 producing cells under high oxygen concentrations, for example atmospheres of at least 70% O2 and at least 5% CO2.  In addition to using peripheral mononuclear blood cells PAL as the source of leukocytes containing the IL-2 producer cells, it is also possible to use buffy coat cells which are readily available as a waste by-product from blood banks.
