Abstract: To measure undulatory wear of the rails, a carriage moving along a railroad track has three measuring bases formed by girders each supported on two rollers and each having a rail sensor providing a measurement of deformation of the rail intermediate the support rollers defining the respective measuring base. The measuring bases have different lengths to provide measurements of the amplitude of undulations of given wavelength values. The length of each successively shorter measuring base is related to the length(s) of the longer one(s) to include amplitude measurements for wavelength values not provided by the longer measuring base(s).

Abstract: A fiber sheet manufacturing apparatus, such as a paper machine, is described, including a rotary through dryer for drying the sheet material on the same foraminous conveyor where it is initially formed. The dryer is provided with a plurality of separate vacuum chambers circumferentially spaced within the foraminous dryer drum, which are each in registration with a different one of a plurality of sources of hot air outside of the drum. The hot air is transmitted through the sheet material and the conveyor into the vacuum chambers to dry the sheet material. Each of the vacuum chambers and the hot air sources is independently controlled to provide different temperatures and vacuum pressures for more efficient and versatile operation. The air is transmitted from the vacuum chambers out of the drum through their separate exhaust conduits extending through the end of the drum and spaced from the drum support bearings.

Abstract: A concentrator for use in a PCM telephone network. The concentrator has conventional units such as line equipments, a space concentration network and a coder/decoder-PCM sampler and additionally includes a time cross-connection network and two different types of junctors, one type being a complete junctor and the other type (a simplified type) conducting only during the conversation part of a call. The concentrator therefore arranges firstly for a normal junctor to set a call up, then subsequently releases it, substituting it by a simplified junctor. This substitution causes a complementary modification of the time connection in the time connection network to keep the same connection channel with the exchange.

The compounds display valuable pharmacological properties, and are particularly useful as analgesic agents.

Abstract: The present invention encompasses compounds of the formula ##STR1## AND THE PHARMACEUTICALLY ACCEPTABLE ACID ADDITION SALTS THEREOF WHEREIN R represents hydrogen or hydroxymethyl. The compounds of the present invention are prepared by condensing N-carbobenzyloxyserine or 2-carbobenzyloxyamino-3-hydroxy-2-hydroxymethylpropionic acid with p- N,N-bis(2-chloroethyl)!phenylenediamine hydrochloride and removing the carbobenzyloxy protecting group by catalytic hydrogenation. These compounds are useful as cytotoxic agents, in particular, antitumor agents.

Abstract: A device for reading out the position of a movable member comprising a sc carried by that member and having equidistant coded references. Each reference is different from the others. A stationary optical system forms the image of a portion of the scale on a fixed detector. The detector comprises a linear matrix of photo detectors regularly distributed at predetermined intervals and associated with electronic means which identifies the coded reference whose image is formed on the matrix and reads out the serial number of the photo element on which the leading edge of the coded reference is formed.

Abstract: An improvement to a conventional slap-hammer which allows the hammer to be rotated by a pneumatic wrench or like device. A universal joint is attached to the top of the slap hammer to enable the latter to be rotated by the output shaft of a pneumatic wrench. The housing of the wrench is held by a closable harness that encircles the housing when closed and thereby prevents the output shaft from becoming disengaged from the universal joint.
