Abstract: Dispositif pour engendrer des ondes acoustiques dans le sol par percussion d'une masse sur une cible comportant un élément de guidage allongé pour guider le déplacement de la masse.  La cible est fixée à une première extrémité de l'élément de guidage et la masse est retenue par intermittence à l'élément de guidage au voisinage de sa seconde extrémité.  L'élément de guidage est monté pour pivoter entre une première position pour laquelle la masse peut se mouvoir sous l'effet de son propre poids de la seconde extrémité de l'élément de guidage vers la cible fixée à la première extrémité, la cible étant couplée avec le sol dans cette première position, à une seconde position pour laquelle la première extrémité de l'élément de guidage est plus élevée que sa seconde extrémité, la masse se mouvant alors sous l'effet de son propre poids de la première extrémité à la seconde extrémité de l'élément de guidage où elle est maintenue par intermittence.

Abstract: 4/dr                                    58519-4 ABSTRACT OF THE DISCLOSURE    A digital time dependent relay is constructed for long time-lags and converts an incoming current signal into a binary number (n).  The relay comprises one or more binarily controlled frequency multipliers, such as a Binary Rate Multiplier, or Decade Rate Multiplier, the control signal of which consists of the binary number and an input frequency which is determined by an adjustable oscillator and occurs when the incoming input signal exceeds a predetermined level.  The output frequency of the multiplier is supplied to a binary counter which delivers an output-signal when its contents reach a predetermined value.  By a series-connection of two or more multipliers, an output frequency is achieved which is proportional to a second or higher power of the binary number and thus to the same power of the incoming current signal.  The desired time-lag is determined by the frequency of the oscillator, by the control signal to the multiplier, and by the predetermined value of the counter.

Abstract: METHOD AND APPARATUS FOR MOLTEN    METAL FLOW DIFFUSION                        Abstract of the Disclosure A method and apparatus for reducing longitudinal distortion in float glass is disclosed.  A beam or barrier having cross-hatched grooves is installed below the advancing float glass ribbon in a float glass-forming chamber.  The barrier acts to divert or diffuse laterally the molten metal which is being drawn by interfacial drag with the bottom surface of the glass.  The diffusion evens the heat on the undersurface of the glass and reduces glass distortion.

Abstract: ABSTRACT OF THE DISCLOSURE        An automatically locking slider includes a locking spring for locking the slider in position on a slide fastener.  The locking spring has at one end a locking prong movable into and out of a slide fastener guide channel and at the other end a first retaining portion resting on a slider body.  The locking spring is further provided with a resilient tongue or tongues constituting a second retaining portion which is supported by a pivot means in a plane above and remote from the general plane of an upper body wing so as to permit the locking prong to move angularly about the pivot means.  The advance in the art is in that the locking prong of the locking spring is prevented from accidentally  dis-engaging from the fastener elements of the slider fastener.

Abstract: Abstract A novel process for the preparation of optically active 2-(2',2'-dihalogenovinyl)-cyclopropane-1-carboxylic acids substituted in the 3-position, and derivatives thereof, and also novel 4-(2',2',2'-trihalogenoethyl)-cyclobutane-1-sulfonic acid salts are described.     In the said process, racemates of specific cyclobutanones are reacted either with the sulfurous acid salt of an optic-ally actlve base or in the presence of water and sulfur dloxide with an optically actlve base to give a 4-(2',2',2'-trihalogenoethyl)-cyclobutane-1-sulfonic acid salt.     The resulting pure diastereomers are either reacted direct in the presence of a base to give optically active 2-(2',2'-dihalogenovinyl)-cyclopropane-1-carboxylic acids or acid derivatives, or, alternatively, the pure diastereomers are decomposed to optically active cyclo-butanones, after which the latter are converted in the presence of a base to the desired optically active cyclo-propanecarboxylic acids, which in the main are obtained in the cis-configuration.      The cyclopropanecarboxylic acids and their derivatives, obtained according to the invention, can be used to prepare agents for pest control, especially insecticides, or can be employed direct as agents for pest control.
