Abstract: Abstract A T-joint fitting comprising two parts for clamping to an existing length of pipe encloses a piston, which is axially displaceable by firing of a cartridge. The piston cuts a hole in the wall of the pipe and is provided with a transverse passage, which will serve for conducting fluid from the pipe to a second passage in the fitting.             The length of the piston is selected so its front, cutting edge rests against the envelope wall of the pipe, when its back face is about level with the open end of the first passage. The cartridge is a disc-shaped shell, having about the same diameter as the portion of the housing enclosing the first passage, this portion having external threads. There is an exenctrically located socket for a firing cap at the face of the shell to be turned out-wards in use.             A cup-shaped nut engaging these external threads has in its inner bottom surface a recess for reception of the cap containing socket, the recess being further adapted to make the firing cap accessible to a firing pin.

Abstract: PRODUCTION OF POLYESTER FILAMENTS  OF HIGH STRENGTH POSSESSING AN UNUSUALLY STABLE INTERNAL STRUCTURE EMPLOYING IMPROVED PROCESSING CONDITIONS                    Abstract of the Disclosure An improved process is provided for the formation of a high performance polyester (at least 85 mol percent poly-ethylene terephthalate) multifilament yarn.  The product possesses a high strength (at least 7.5 grams per denier) and an unusually stable internal structure which renders it par-ticularly suited for use in industrial applications at elevated temperatures.  The filaments are melt spun and uniformly quenched under relatively high stress conditions to yield an as-spun filamentary material of relatively high birefringence which is passed in-line from the quench zone to a first draw zone provided at a temperature below the glass transition temperature of the as-spun filamentary material where it is drawn.  The first draw zone in a preferred embodiment con-veniently is provided at ambient temperature (i.e. at about 25°C.) thereby resulting in an energy savings over prior art processes.  Additionally, it surprisingly has been found that in combination with the other process steps the first draw step can be carried out on a stable basis in the substantial absence of neck drawing.  Following subsequent drawing at least 85 percent of the maximum draw ratio of the as-spun filamentary material is achieved.

Abstract: SAFETY LOCK FOR RADIOGRAPHY EXPOSURE DEVICE        Abstract A safety lock for securing a radiation source in a radiography exposure device is disclosed.  The safety lock prevents the inadvertent extension of the radiation source from the exposure device.  The exposure devices are used extensively in industry for nondestructive testing of metal materials for defect.  Unnecessary exposure of the radio-grapher or operator occurs not infrequently due to operator's error in believing that the radiation source is secured in the exposure device when, in fact, it is not.  The present invention solves this problem of unnecessary exposure by releasingly trapping the radiation source in the shield of the radiography exposure device each time the source is retracted therein so that it is not inadvertently extended therefrom without the operator resetting the safety lock, thereby releasing the radiation source.  Further, the safety lock includes an indicator which indicates when the source is trapped in the exposure device and also when it is un-trapped.  The safety lock is so designed that it does not prevent the return of the source to the trapped, shielded position in the exposure device.  Further the safety lock includes a key means for locking the radiation source in the trapped position.  The key means cannot be actuated until said radiation source is in said trapped position to further insure the safety lock cannot be inadvertently locked with the source untrapped and thus still extendable from the exposure device.

Abstract: ABSTRACT OF THE DISCLOSURE     For the purpose of briquetting organic solid materials, such as brown coal or bituminous coal, the materials are heated by hot water and/or steam and under super-atmospheric pressure to temperatures exceeding 160°C.  After discharging the organic solid materials, which have become dried to a great extent, the generated steam is separated by withdrawing the steam, using sub-atmospheric pressure and thereby separating the same, without a substantial cooling effect, and the bitumen-forming substances present within the organic solid materials thereby rapidly become homogeneously distributed.  These homo-geneously distributed binding agents give compressed briquettes having high strength and good mechanical properties while using substantially reduced compacting pressures as compared with known briquetting processes.
