Abstract: A B S T R A C T - - - - - - - -A directional array of transducers is disclosed.          Acoustic transducers are arranged colinearly and in pairs symmetrically about a center line of the directional array.          The distances of the acoustic transducers on either side of the center line of the array are neither linear nor monotonic.          These distances are calculated using a recursive far field response formula which effectively reduces sidelobe magnitudes to a desired design amplitude envelope.  The response produced is highly directional, comprising one main lobe and a plurality of sidelobes each less than the desired design envelope, which is substantially lower than the main lobe but of arbitrary (e.g., stepped) shape.

Abstract: ABSTRACT:           The invention relates to an arrangement com-prising a gas and/or vapour discharge lamp which includes a discharge tube.  An electronic auxiliary  device is arranged in parallel with the discharge lamp.  This aux-iliary device ensures that in the operating condition the lamp is shunted briefly during each half cycle of the power supply.  With an arrangement according to the invention, the lamp is of a type in which the discharge tube has a temperature of at least 200°C in the operat-ing condition.  The auxiliary device is connected to sen-sor elements which ensure that the lamp is not shunted in the period of time in which the lamp has not yet reached the operating condition.  This achieves reliable starting of the lamp.

The length of the outer member is adjustable to the thickness of the concrete layer to be poured.  A cylindrical inner member, with a closed bottom and an open top, is inserted into the outer member.  As the concrete is poured, it is received in the inner member and forms the test core.  After the concrete sets, the inner member is removed, resulting in a hole in the concrete. The cap member is alternatively adapted to close the bottom of the outer member, prior to mounting the outer member on the form, to permit the hole to be subsequently filled, if the form has been removed.

A support -arc, having feet at each end, passes through apertures in the locking bars,  Springs interconnecting each locking bar and the ladder urge the locking bars to an unlocked position where the support arc is free to pass through the apertures.  When weight is applied to the ladder, the locking bars are urged to a locked position, against the springs, where the sides of the apertures . engage the support arc to lock it against further movement,  By adjustment of the support arc, the feet may be raised or lowered to accommodate any irregularities in the support surface so that the ladder will stand vertically.      The levelling device may also be applied to tables, chairs, trestles or like articles.

Abstract: "ABSTRACT" "Method of manufacturing a display tube".    Upon adhering the display screen to the cone and upon evacuating the display tube, the display screen and the cone are subjected to temperature treatments in which stresses occur in the display screen which may cause fracture of the display tube. In order to reduce the possibility of fracture, during the temperature treatment measures are taken which influence the temperature dis-tribution over the display screen and the cone in such anner that the occurrence of stresses in the display screen is counteracted. In an embodiment, in the furnace 60 for adhering the display screen 41 to the cone 42, a heat shield 46 is provided at some distance above the central part of the display screen 41. As a result of the heat shield 46, fewer tubulences of the heated air occur at the central part of the display screen 41, with which the dis-play tube 40 is warmed up and which is conveyed from the neck 43 past the display tube 40. The display screen 41 thus is warmed up   more slowly, which considerably reduces the value of the stresses occurring in the display screen 41.

Abstract: ABSTRACT OF THE DISCLOSURE      A nondenaturing zwitterionic detergent for proteins which, for example, consists of an effetive amount of 3-[(3-cholamidopropyl)dimethylamino]-1-propanesulfonate (CHAPS). This detergent is of extreme interest in the biological study of pro-teins due to its nondenaturing characteristic. Other examples of the group may be prepared from different alicyclic compounds, for example, utilizing cholic acid and in others deoxycholic acid and dehydroabiotic acid. A process for the preparation of these compounds starts with cholic or the equivalent and from this is prepared the triethylammomium salt in tetrahydeofurna (THF).         After the salt is completely dissolved in THF, ethyls chloroformate is added and the flask cooled to 0°C. Then the mixed anhydride which forms is reacted wtih dimethylaminopropylamine to form the dimethylaminopropyl derivative of a carboxylic acid amide. Finally, the tertiary amine group is reacted with propanesultone to give the sulfobetaine product.  An improved procedure for preparation of these compounds and especially for the last step (as for CHAPO) to react the N-(3-dimethylaminopropyl)cholamide with sodium 1-chloro-2-hydroxy-3-propanesulfonate.
