Abstract: An oxygen respirator, comprises a portable container having a cartridge chamber with a cylindrical oxygen-supplying chemical cartridge centrally located in the chamber and with a replaceable CO2-absorbing cartridge concentrically surrounding the chemical cartridge. The cartridge chamber is closed by a baseplate which includes a mouthpiece connection defining a mouthpiece passage for respirator air for the user which connects downwardly into the chamber through an associated check valve for flow downwardly through the annular CO2-absorbing cartridge and upwardly through the oxygen-supplying chemical cartridge which, after initial ignition, supplies oxygen to the respiratory air which is circulated back to the mouthpiece passage either directly or through a breathing bag which is mounted in the respiratory air breathing passages.

Abstract: An improvement of the SNAM ammonia-stripper integrated urea process is disclosed, wherein a gaseous stream obtained by decomposing hydrocarbons is fed to an adiabatic ammonia stripper placed downstream of a carbamate decomposer, the adiabatic stripper also receiving a solution of urea which is rich in ammonia coming from the carbamate decomposer. The thus enriched gaseous stream (NH3, CO2, H2O) is processed in a CO2-absorber (or carbamate reactor) and the process proceeds in the urea synthesis reactor. Recycling and recovery loops are provided between the several reaction and/or decomposing units. Surprisingly, enough, the stripping on NH3 and CO2 takes place adiabatically and the drop of the CO2 partial pressure in the stream fed to the carbamate reactor has no bearing on the efficiency of the carbamate conversion which, according to the current technical teachings, requires an increase of the CO2 partial pressure.

Abstract: A pigment-free coating composition comprising an acidic dispersion of colloidal titania, colloidal silica and hydroxylated silsesquioxane in an alcohol-water medium. A coating of the composition cured on a plastic substrate such as polycarbonate results in a hard, abrasion-resistant protective coating. Such coatings transmit visible light, but absorb wavelengths of ultraviolet light which cause degradation of the substrate surface and resultant adhesion-loss of the protective coating upon weathering. A cured coating of these compositions deposited on metal substrates such as aluminum results in a hard, abrasion resistant coating which offers slightly more corrosion protection than such a composition without colloidal titania.

The box (6) is aligned coaxially with the filling funnel (20). A pressure cylinder (4) then, via a crosshead (7) and a crosshead stop (12), pushes the box (6) with its open end face onto the narrowed end of the filling funnel (20) and thereafter, via a further crosshead stop (11) and a filling-funnel crosshead (8), pushes the filling funnel (20) together with the box (6) further towards the bar-shaped parts (38), until their ends (39) have entered the filling funnel (20) and are flush with the outlet end of the latter. Another pressure cylinder (3) then pushes the filling funnel (20) alone further and out of the box (6). The filling funnel (20) is thereafter divided longitudinally and the halves (21, 25) are retracted transversely to the axial direction of the bar-shaped parts (38), whereupon, finally, the box (6) is pushed by a pressure cylinder (13) further onto the bar-shaped parts (38) as far as the container (40).

Abstract: As apparatus for sensing reflected light patterns in the presence of a welding arc has an image-sensing means. Means is provided for directing one or more pulses of light of short duration at a workpiece. Each pulse has a peak intensity greater than that of the welding arc. A means is provided for blocking the light image from the sensing means except during a pulse from the light-directing means. An image sensing process includes the steps of directing light at the workpiece in one or more pulses, each of greater intensity than the welding arc. Light from the pulse reflected from the workpiece is sensed during the pulse, and sensing of light from the welding arc is blocked during the absence of a light pulse. This apparatus and process allows improved sensing of the light patterns in the presence of the welding arc and welding sparks.

Abstract: A system, for loading a group of elongated rods into a tray from a ramp, which includes a controllable rod stop located on the ramp, an air-tight envelope, and a tray positioning mechanism. The envelope has one end attached to the ramp's lower end and has a hole in its lower surface near the ramp's lower end. The envelope is stiff enough to self-inflate with air and to self-project its opposing end away from the ramp's lower end, when the envelope is left free. The tray positioning mechanism places the tray next to and under the envelope when the rods are to be loaded. When the rod stop is disengaged, the rods roll onto the envelope and are lowered into the tray as the weight of the rods push the air out of the envelope through its hole.

Abstract: A calender wherein a permanently installed main roll cooperates with at least one exchangeable roll to provide a nip for the passage of a web of paper or the like. The end portions of the exchangeable roll are mounted in bearings which are insertable into and extractible from sockets provided in levers which are pivotably mounted in the frame of the calender. The calender has a transporting unit which is provided with grippers for the bearings and with motors which reciprocate the grippers to extract the bearings from their sockets after the levers are pivoted to positions in which the exchangeable roll is spaced apart from the main roll. The transporting unit thereupon transfers the exchangeable roll onto a mobile rack which can be transported to a station where the exchangeable roll is repaired. The same rack or a discrete second rack can deliver a refurbished exchangeable roll to the transporting unit for introduction of the bearings on the refurbished roll into the sockets on the levers in the frame of the calender before the levers are pivoted to move the refurbished roll into engagement with a running web or with the main roll. Locking devices are provided to releasably hold the bearings in their sockets, and additional locking devices are provided to releasably hold the bearings in sockets which are provided on the rack or racks. The transporting unit can constitute a robot whose grippers then constitute effectors and whose operation is automated to start a roll exchanging operation as soon as one or more sensors in the calender ascertain that the quality of the exchangeable roll is unsatisfactory for further treatment of running webs.

Abstract: A method and a device for control of a regenerative hydrostatic drive system, particularly for vehicles, comprises a primary engine (9) with a power transmission (5) to a drive axle (6) and a hydrostatic machine (2), which is selectively connectable to the same drive axle (6) and connected to a hydraulic fluid circuit, which comprises at least one high pressure supply (3) and one low pressure supply (4) of said hydraulic fluid, the hydrostatic machine (2) during braking of a vehicle being connected with said drive axle (6) and operating as pump provides a charging of the high pressure supply (3), while the last-mentioned during acceleration of the vehicle drives the hydrostatic machine (2) as a motor and hence also the drive axle (6). For allowing the use of smallest possible hydraulic fluid volume simultaneously with maximum utilization of said volume the invention suggests that during the flow of the hydraulic fluid in the direction from the high pressure (3) to the low pressure (4) supply is detected the achievement of a predetermined fluid volume in one of the supplies (3, 4) for determination of the quantity of hydraulic fluid remaining in the high pressure supply (3). In case the detection of the predetermined fluid volume is made in the low pressure supply a correction coefficient for the temperature of the hydraulic fluid is incorporated in said quantity determination which in this case is made while taking the given total hydraulic fluid volume into consideration. Thereafter, the change of the remaining volume of hydraulic fluid in the high pressure supply (3) is continuously determined on the basis of the instantaneous speed and displacement of the hydrostatic machine (2) at the same time as the smallest volume of hydraulic fluid is determined, which at instantaneous speed and displacement of the hydrostatic machine (2) is required for allowing a jerk-free shifting to driving only by means of the primary drive engine (9), the results of said two determinations being continuously compared and when found equal brought to initiate said shifting.
