Abstract: ABSTRACT OF THE DISCLOSURE           In accordance with this invention, it has been found that oxygen analogs of 6.beta.-aminopenicillanic acid and biologically active derivatives thereof can be formed from esters of 6-oxo-penicillanic acid.  For example, 6.beta.-phenoxyacetoxypenicillanic acid - an oxygen analog of penicillin V may be formed from an ester of 6-oxopenicillanate.  The ester of 6-oxopenicillanic acid is formed by a diiospropyl carbodiimide/dimethyl sulfoxide oxida-tion of the corresponding ester of 6.alpha.-hydroxypenicillanic acid.          The oxygen analogs are formed by reducing the ester of 6-oxo-penicillanic acid to the corresponding 6.beta.-hydroxypenicillanate and then forming the desired analog by acylation.

Abstract: ABSTRACT           A circuit arrangement for supplying alternating cur-rent to an electric discharge lamp has a pair of input ter-minals for connection to an alternating voltage source and a series arrangement of a stabilizing inductor and lamp being connected across the input terminals.  A circuit consisting of a semiconductor switch is connected in shunt with the lamp and a control circuit is provided for triggering the semi-conductor switch.  This control circuit is coupled to a con-trol electrode of the semiconductor switch and includes a branch having an element with a relatively short time con-stant such that the switch is triggered on and off at least several times during every second half cycle of the alternat-ing voltage source.  This arrangement operates in the operating condition of the lamp and, together with a stablilizing ballast, generates voltage peaks which ensure rapid reignition of the lamp at each half cycle of the alternating current supply.

Abstract: PAUSE DEVICE FOR TAPE RECORDER                ABSTRACT OF THE DISCLOSURE      In a tape recorder in which a pinch roller is pressed against a motor-driven capstan to move a magnetic tape at a constant speed, a pause device includes an actuator con-nected to a pinch roller carrier to stop the tape movement by separating the pinch roller from the capstan.  Continued movement of the actuator to an over-stroke position latches a switch controller to the actuator, and release of the actu-ator to an intermediate position draws the switch controller with it to allow a switch in the power supply circuit of the motor to open, stopping the motor after the tape has stopped.          Restarting from the paused condition involves moving the actu-ator to the over-stroke position to release the switch actuator, then allowing the actuator to return by spring force to the unactuated position to allow the pinch roller to resume press-ing the tape against the capstan.

Abstract: ABSTRACT OF THE DISCLOSURE     Granular starch-based gums which are readily soluble in water and which exhibit excellent storage stability and high clarity in aqueous solutions.  These gums are useful as replacements for gum arabic, particularly in lithography.  They may also be used as emulsifiers and stabilizers in foods, drugs and cosmetics.  Additional uses in printing inks, paints, and wherever gum arabic is employed, are also contemplated.  They comprise granular high-amylopectin starches which have been thinned (acid-thinned, oxidative-thinned or enzyme-thinned) and which have a degree of substitution of a nonionic substituent from about 0.1 up to about 0.3.  "High-amylopectin" starches contain 30% or less amylose.  The possible nonionic substituents include alkyl, hydroxyalkyl, cyanoalkyl, amidoalkyl and acyl groups.  In addition, carboxyl and amino groups can be used to increase the light sensitivity of the starches in sensitizer film solution applications.  Lithographic films of high clarity are made possible by using the starch derivatives of the invention.  The starch-based gums of the invention are rendered floc-free or clarified after gelatinization or cooking.  The enzyme-clarified gum forms a substantially clear solution when solubilized at pH greater than 5, and the solution remains stable for long periods from 1-12 months.

Abstract: A B S T R A C T A method and device for the directional blasting of rock and other materials is provided.  A blasting tube, the cross-sectional shape of which is crescent shaped, has a substantially rigid elongated body with a longi-tudinal air space therein and means to separate an explosive charge from the air space.  Preferably, the separating means consists of a concave portion of the wall of the tube and the cross section of the air space is also crescent shaped.  After the bore hole is drilled, the tube and the explo-sive material is inserted into the bore hole with the air cushion provided by the tube being oriented in the hole between the explosive charge and one side of the bore hole in a direction relative to the explosive charge op-posite to which the maximum breaking and shattering forces are desired. The explosive charge can then be detonated without the use of stemming mater-ial other than the usual material to plug the outer end of the bore hole. When the explosive charge consists of individual elements of cylindrical form, the charge can be attached to the blasting tube prior to insertion thereof into the hole.  The concave exterior portion of the tube is then adapted to hold the cylindrical charge.

Abstract: ATTACHMENT OF ELECTRIC LEAD WIRES         TO PIPELINES     Abstract of the Disclosure The invention relates to a method for connecting electric lead wires to metallic pipe lines.  According to the novel method, the lead wire is first connected to a small sheet metal contact tab by known techniques, such as welding, soldering, brazing, crimping, etc.  The contact tab with the lead wire thus connected is then joined to the pipeline by means of explosive welding.  This method has the important advantages that the lead wire can be connected to a pipeline with no heat affected zone and/or cracking in the pipe wall.

Abstract: ABSTRACT OF THE DISCLOSURE      Dilute sulfuric acid contaminated with acetic acid and hydrogen chloride is purified with the resultant formation of concentrated sulfuric acid and acetic acid. To this end, the contaminated sulfuric acid is heated in a first step to at most 60°C under 25-30 mm Hg so as to expel all of the hydrogen chloride together with minor proportions of acetic acid and water. In a second step, the sulfuric acid is heated to at most 165°C under 20-25 mm Hg so as to distal off the bulk of ace-tic acid together with water. In a third step, the sul-furic acid is cooled sown to 60-90°C, diluted with 10-30 weight % of water with agitation and while cool-ing is continued. Following this, the sulfuric acid is heated to 160-165°C under 20-25 mm Hg and thereby freed from the water and residual acetic acid.°
