Abstract: A B S T R A C T     The continuous type belt (3) is arranged round two rollers (25), one of which is driven. One straight section of the type belt (3) contacts over its entire length the support designed as a platen (23).            In order to avoid grooves on the platen (23) caused by the rotating type belt (3), and to achieve a distribution of other kinds of wear of the platen (23) over its circumference, a gear motor (27) causes the platen (23) to rotate very slowly (approximately 1 revolution in 72 hours).            The platen (23) can also be rotated without gear motor. For this purpose, the longitudinal axis of the platen (23) is slightly inclined relative to the edge of the type belt (3). This inclination effects a small movement component in the direction of the platen circumfe-rence while the type belt (3) slides along the lateral surface of the platen (23), said component causing a slow revolution of the platen (23).

Abstract: Abstract Method and apparatus for manufacturing a wiring harness.          Apparatus mass terminates wires to an automatically fed strip of terminals then mass inserts terminated wires into cavities in a connector housing.  A shuttle having tele-scoping wire guide tubes and a wire clamp reciprocates to deliver wires with leading ends in a straight array axially at a first fixed spacing to an operating zone and then to an insertion station.  The telescoping tubes collapse to extrude leading ends of wires into the operating zone where the wires are deflected laterally of their axes various amounts and rolled into grooves in a template which restores the leading ends to a straight array at a second fixed spacing for termination to a strip of terminals at the second fixed spacing.  Shuttle then retreats as tubes expand to draw in terminated wires, and then advances to insert terminals on leading ends into cavities at first fixed spacing in a connector housing.  Clamp 34 is released and shuttle retreats over stationary wires until wires are exposed to strip and shear blades remote from housing.

Abstract: ABSTRACT OF THE DISCLOSURE An anaesthetic vaporiser of the by-pass type has a sump 7 with an outlet flow path comprising a first run 27 leading upwardly, a second run 30 leading downwardly and a third run 32 leading upwardly again.  A duct 23 connects the lower end of the run 30 with the lower part of the sump and in normal operation is sealed by the sump liquid. However, if the vaporiser is displaced such that the liquid flows from the sump into runs 27 or 30 of the outlet flow path the liquid inevitably drains from the duct 23.  A flow path forinflowing gas is thereby opened directly to the downstream end of the run 30, preventing the over-administration of vapour from the device and removing any danger of liquid anaesthetic being blown through the device from the runs 27 and30.

Abstract: ABSTRACT There is provided a combustion unit which includes a cylindrical mantle capable of providing a site at which most or all of the actual combustion can take place.  This allows the mantle to absorb much of the heat of combustion and to become a source of radiant energy in the form of infra-red heat.  By surrounding the mantle with a light-transmitting but imperforate member, such as a silica quartz tube, the combustion and the products of the combustion can be confined, while allowing a very large portion of the generated heat to pass out of the unit in the form of radiant energy.  Also, some of the heat of combustion would be transferred as sensible heat through conduction, and the flue ducting from the downstream end of the combustion unit can be directed in such a way that it allows additional heat in the flue gases to be transferred to the air to be heated.  The combustion unit herein defined can be used in an infra-red heater arrangement, and can also be used to heat liquid such as water.

Abstract: ABSTRACT            Deflection wedges are positioned in a generally horizontal drill hole in a predetermined orientation by means of a device which fits on the end of a drill string and is positioned in the hole. The deflection wedges positioned at the end of the device, and the device includes a unit which triggers at the predetermined angular orientation, to indicate that the wedge is correctly oriented.  The orientation unit has a through passage for pressure fluid and a transverse passage intersecting the through passage. A blocking member is movable in the transverse passage and at a particular orientation moves along the transverse passage across the through passage.  When crossing the through passage, the blocking member is entrained by the pressure fluid flow and moves to a position where it blocks the through passage, thus providing a signal to an operator that the unit is correctly positioned. The wedge is then secured in that position and the device withdrawn from the hole.

Abstract: ABSTRACT OF THE DISCLOSURE:           A method of preparing spent nuclear fuel rods from a nuclear reactor for long-term storage in a copper container, which method comprises the steps of embedding the fuel rods in copper powder within the container, closing the container with a copper lid, and subjecting the closed container to hot isostatic compression at a pressure and a temperature sufficient to form the container, the powder and the lid into a coherent mass in which the spent fuel rods are embedded.  The present invention makes use of the knowledge that a copper container is extremely well suited for long-term storage of spent nuclear fuel rods from a nuclear reactor due to its high resistance to corrosion by water.  The present invention is based on the realization that the resistance of the enclosure can be improved by embedding the fuel rods in copper powder within the con-tainer and effecting a pore-free unitary body of all enclosing materials.  This is preferably achieved at such a temperature that the gas present in the cladding tubes of the fuel will not generate a pressure sufficient to cause creep rupture in the tubes.

Abstract: ABSTRACT OF THE DISCLOSURE           In a serum separator, a sampling tube fits inside of a test tube.  The sampling tube is provided with an elastomeric piston head at the lower end thereof having an annular lip to engage and form a seal with the inner sidewalls of the test tube.          The upper side of the lip is provided with irregularities to break the seal between the lip and the test tube wall upon removal of the samplint tube from the test tube.  A porous plastic filter body is mounted in a cavity in the piston head. The piston head defines a one-way valve in the form of a ball chamber containing a ball check.          When the sampling tube is pushed into the test tube with a blood sample in the test tube, serum will pass through the filter body and valve into the interior of the sampling tube.  The valve is constructed so that the serum cannot squirt toward the top of the sampling tube.          When the sampling tube has been inserted, the valve will close.  When the sampling tube is withdrawn, the reduced pressure in the bottom of the test tube will cause the ball to wedge in sealing engagement in the closed position to retain the serum sample in the sampling tube and isolate it from the residue in the bottom of the test tube.
