Abstract: A B S T R A C T A device is disclosed for injection syringes for intramuscular and subcutaneous injections in human and veterinary medicine.  The device is substantially in the form of a tube, the inside diameter of which is somewhat larger than the outside diameter of an injection syringe associated therewith. Located within the tubular sleeve are a clamping element and a stop-element, arranged at a distance from each other equal to the desired depth of injection, plus a safety distance between the tip of the needle and the edge of the sleeve. When a certain pressure, acting upon the injection-syringe in the direction of the lower edge of the sleeve, is exceeded, the clamping element releases the body of the syringe carrying the injection needle, allowing the syringe to advance.  The advance of the syringe is halted by stop-element.  The clamp-ing and stop elements may be in the form of beads projecting into the interior of the sleeve and thus constricting the internal cross-section thereof.  The clamping element may also be in the form of a single tongue or of two diametri-cally opposite tongues on the peripheral surface of the sleeve, each of the tongues being provided with a nose.

Abstract: TITLE     MINE ROOF PLATE BEAM FOR A ROOF TRUSS ASSEMBLY     ABSTRACT OF THE DISCLOSURE     An elongated plate beam has a plurality of long-itudinally extending downwardly directed ribs.   The ribs are positioned in parallel spaced relation to form a pair of lateral ribs and a center reinforcing rib.  The plate beam has a preselected length adapted to span the width of a mine passage and includes a top surface arranged to abut a mine roof and a bottom surface.   A plurality of openings are spaced the length of the plate beam and extend through the center reinforcing rib.  A roof plate is positioned in abutting relation with the plate beam bottom surface in overlying relation with each opening.  Roof bolts extend through the roof plates and openings into engagement with the walls of bore holes drilled in the mine roof.  An enlarged end of each roof bolt bears against the respective roof plate to apply an upward force upon the plate beam to position the plate beam in roof supporting relation with the mine roof the entire width of the mine passage spanned by the plate beam.  In one embodiment the roof plates each include a center rib positioned in complemen-tary interengagement with the plate beam center reinforcing rib to increase the surface to surface contact of the roof plates with the plate beam to increase the bearing force applied by the plate beam to the mine roof.

Abstract: ABSTRACT OF THE DISCLOSURE     A medical infusion pump for use in conjunction with a valved elastomeric pumping chamber.  The pump comprises a pair of clamp elements between which the pumping chamber is located and one of the clamp elements is movable relative to the other to effect cyclic compression and expansion of the pumping chamber.  The movable clamp element is constituted by an extension of a solenoid armature and such clamp element moves in a direction away from the fixed clamp element, to permit expansion of the pumping chamber, when the solenoid is energised.  A compression spring acts against the solenoid armature and serves to bias the movable clamp element in a closing direction when the solenoid is de-energised, whereby a compressive force is applied to the pumping chamber.  An electric motor is coupled to the spring by way of a motion translating mechanism and, when energised, the motor functions to change the effective length of the spring and, hence, the biasing force exerted on the movable clamp element.

The sites are reciprocally moved along the tube during the reactive deposition. A high-frequency generator is electrically connected to the burners generating the flames. An apparatus for coating tubes comprises a gas supply system, burners for generating a plasma and means for moving the burners.
