Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to a trench shoring assembly which includes a pair of spaced-apart side walls for vertical disposition within a trench. Spreader pipes and spreader collars interconnect the side walls and allow limited pivotal movement between the side walls.  Each side wall includes outer and inner metal plates connected to a horizontally extending hollow top beam which extends longitudinally along the top of the side wall, two intermediate beams parallel the hollow metal beam and a bottom beam. A hardwood insert is disposed within the top beam to prevent the collapse of the hollow metal beam. A number of hollow beams extend perpendicularly to the horizontal beams and ribbed members extend perpendicularly to the horizontal beams. The side walls of the assembly have a tapered bottom portion which defines a triangularly shaped pointed lower extremity extending between the ends of the bottom portion. A metallic bar is disposed at the pointed lower extremity and extends between the ends of the bottom portion and protects the bottom of the side wall against abrasion.  A U-shaped member is welded to the main frame, and, in turn, a spreader collar is welded to the U-shaped member so that a force applied to the spreader collar is transferred directly to the main frame.  Each spreader pipe spaces the side walls apart between two spreader collars to which the spreader pipe is attached by spreader pins.  Lifting rings are slidably attached to the spreader pipes for lifting the assembly.  A plurality of flanges extend from a spreader pipe and are connected by locking pins to mating flanges which extend from another spreader pipe of another vertically stacked trench shoring assembly .

Abstract: ABSTRACT:       A transmission path between two terminal stations for transmitting digital information signals at a predeter-mined rate in one direction via a forward path and in the other direction via a return path comprises regenerative transmitting tele-location commands to the repeaters via the forward path, cattier signals of the rate being on-off modulated in this transmitter by means of an amplitude modulator in accordance with output signals of a command sequence generator, and further comprises in every repeater a loop circuit between forward and return paths having an associated control circuit which cooperates with a detector for the presence of carrier signals in the return path for receiving tele-location commands.  Without the use of addresses assigned to the repeaters a reliably operating control circuit of a simple structure is obtained in a tele-location system of this type by so arranging the command sequence generator that it produces command sequences which are each formed by a pulse train having at least one pulse, the pulses being transmitted by interrupting the carrier signals by means of the amplitude modulator.

Abstract: ABSTRACT          The invention discloses a method of forming gratings suitable for use as walkways etc. The method includes the steps of forming transverse bearer bars from strips of flat plate by punching a series of transverse slots across the cental axis of each plate, then folding the plates to form U-sections with the slots located in the apices of the U-sections.  Longitudinal bars, which are lengths of flat bar, are then inserted as tight press-fits into the slots, and the undersides of the longitudinal bars are deformed laterally between the legs of each U-section to prevent their removal from the slots.  A strong lightweight grating results.

Abstract: ABSTRACT OF THE DISCLOSURE A curtain for surrounding welding and cutting operations, especially electric arc welding and electric arc cutting operations to protect the eyes of otherwise unprotected observers.  The curtain has one surface covered with declivities with faces disposed at angles to the plane of the sheet.  Some light rays passing through the curtain are refracted and undergo a change of direction.  This reduces the exposure of the retina to undesirable intensities by optically enlarging the small arc spot, and presenting the eye with general area illumination instead of pinpoint illumination.

Abstract: ABSTRACT          The invention relates to a process for heating the surface of a substrate and to a burner particularly as part of a spray gun suitable for carrying out the process of flame spraying. In order to improve flame stability and to in-crease the output, compressed air is supplied using annular guide plates arranged in cascade fashion, one above the other and one behind the other in various planes in the direction of the jet. As a result of this, kinetic energy is introduced into the flow of hot gases as the air volume increases, so that almost complete combustion of the hot gases can be achieved at relatively low end temperatures.          The drop-off in temperature of the hot gases in the direction of flow starting from the mouth of the burner is relatively small. Consequently, it is also possible to heat substrates uniformly which, as a result of their particular shape, have a varying spacing from the mouth of the burner. Using the burner, it is even possible to heat shrink films used for packaging objects without over-heating, leading to local destruction of the material, occurring.

Abstract: "HEAT EXCHANGER" ABSTRACT OF THE DISCLOSURE          Heat exchangers which are used in a very moist environment with a relatively low outside ambient tempera-ture, often suffer from severe frosting and consequent in-efficiency and sometimes are completely inoperable leading to inefficient control of the environment.  The present de-vice includes a core in a casing which draws air from the inside and exhausts it exteriorly of the building.  At the same time ambient outside air is drawn through the core at right angles to the exhausting air and picks up heat there-from prior to being discharged into the building.  Control doors are provided firstly to draw warm air from the build-ing and pass it through the core with or without outside ambient air in order to control the temperature of the in-coming air and, if necessary, to defrost the core.  Second-ly to control the temperature of the air discharged into the building if it is too cold and to prevent positive pres-sure from developing inside the building if the outgoing flow is partially restricted by blockage of the portion of the core through which this air is passing prior to dis-charge.

The deflection element is arranged at a spacing K = approximately 15 to 80 mm from the dewatering element.  The longitudinal wire is guided at the inlet section of the dewatering region,  located between its outbound or run-off location at the deflection element and its lowest deflection location,  over a negative pressure zone,  for instance constituted by a suction chamber, which is effective at its underside.  Hence,  at the inlet section there is obtained a reduction in the suspension pressure and the fiber stock suspension is guided with an approximately constant total thickness  lower  into  the dewatering  region,  i.e.  at a relatively flat angle towards the dewatering element, so that there is avoided any backflow at the surface region of the suspension.
