Abstract: A manually operable device for pressing fabric comprising two triangular-shaped jaws, each of which has a flat surface portion. These surface portions face each other and constitute the working surfaces of the device. The two jaws are each secured to a handle. These handles are pivotally joined by a hinge so disposed that the two flat surface portions are separated from each other or are in parallel pressure engagement. The separated position of the surface portions constitutes the loading position of the device for inserting fabric between the two jaws and the other position constitutes the pressing position for pressing fabric inserted between the two jaws. Springs coacting with the handles bias the same into one or the other of the two positions. One of the jaws is hollow and incorporates an electric heating element for heating its flat surface portion, an adjustable thermostatic control for selectively adjusting the heat output of the heating element and an indicator lamp for indicating the state of energization of the heating element. The other jaw comprises a solid flat metallic plate.

Abstract: 1491645 Thermal processing of lump shale NI INST SLANTSEV and SLANTSEPERERABATY - VAJUSCHY KOMINAT "KOKHTLA - YARVE IM VI LENINA 1 April 1976 [1 April 1975] 13319/76 Heading F4B [Also in Division C5] A vertical retort for the thermal processing of lump shale comprises a low-temperature carbonization shaft 2, gasifying shaft 3 and a cooling shaft 4. The shaft 2 is divided by two vertical perforated walls 5 into two low-temperature chambers 6 and a chamber 7 for supplying and distributing a heat carrier some of which is generated from the burner 11 and gas supply 12 and some of which rises from the gasifying shaft 3. Lump shale is fed from the bins 13 to the hot side of chambers 6 next to chamber 7. The heat from chamber 7 produces a steam-gas mixture which rises and is filtered by the density of the bed so that it reaches the off-takes 17 in relatively dust free condition. The gasifying shaft 3 has side chambers with heat generated by burners 11 and gas supply 12. Semicoke produced in the chambers 6 is gasified in the shaft 3 and solid residue passes to the cooling shaft 4 where temperature is lowered by a cooling gas from a supply 18. Finally solid residue passes to the bins 19 and into liquid seal containers 20, whence it is discharged by conveying devices to ash heaps.

Abstract: A transmission system for transmitting essential torque between two locations whose relative positions can change within certain limits, such as between the gearbox and rear axle of an automobile. The system includes a flexible shaft of fibre-reinforced plastics material which connects said locations. The two ends of the shaft are rigidly attached at said locations and the shaft has a sufficiently low Young's modulus in the longitudinal direction and low flexural stiffness to enable positional changes between said locations to be taken up by bending of the shaft. To this end the shaft has the form of a coreless tubular shaft in which the tubular wall comprises a substantially homogenous material with the fibres distributed substantially uniformly over the whole cross-section. The fibres are suitably carbon fibres, forming an angle to the longitudinal direction of the shaft of between +/-40 DEG  and +/-50 DEG , preferably between +/-43 DEG  and +/-47 DEG .

Abstract: A nut device permitting securement of and to thin panel members. An axially extending, internally threaded shank has two laterally extending flanges interconnected to one end, the flanges being bent downward. Two beam members extend laterally from the shank in a direction which is generally perpendicular to the flanges, the ends of the beam members being bent upwardly toward the flanges. The nut is inserted in a slot in the panel by positioning the beam members parallel to the slot, pushing downwardly on the beam members to flex the flanges so that the beam members may be rotated clockwise beneath the panel. The flanges and beam members cooperate to frictionally clamp the panel and resist lateral and rotational displacement relative to the panel. A specially configured tool is also disclosed.

Abstract: A method of encapsulating radioactive waste including withdrawing radioactive liquid having a retardant therein from a source. The retardant may including borates, or other additives, which retard the setting of cements by preventing hydration at cement particles in the mix. The liquid is mixed with ordinary Portland cement and subjected to long term shear far in excess of that needed to form ordinary grout. The use of shear to overcome set retardation, and similarly, the deliberate regulation of acceleration of set in hydraulic cement pastes by the utilization of retardants plus shear produces a thixotropic paste with extreme moldability which will not bleed, and finally sets more rapidly than can be expected with normal mixing to form a very strong product.
