Abstract: In a table comprising a table-top that can be adjusted in height and/or inclination relative to the trestle, and a spring arrangement provided between the trestle and the table-top and serving to counterbalance the weight of the table, the table-top (6) is connected to the trestle at its rear edge by disengageable stops and at its front edge by clamps. The spring arrangement comprises a torsion bar spring (11) mounted preferably on the trestle (1) and provided with at least two radial arms (15, 21) bearing against the trestle (1) and the lower face of the table-top (6), respectively. Such a spring arrangement is of particularly simple design and requires only little space. Further, the torsion bar spring offers a favorable spring characteristic. A particularly soft spring effect can be achieved by the use of a stack of leaf springs (31) as torsion bar spring. The stop arrangement comprises pins (61) projecting from the rear edge of the table-top into a cable duct (2) where they are held by a toothed slide (64). The clamps are formed by clamping pieces (90) which can be displaced in opposite directions by rotating a threaded spindle (82) seated at the front edge of the table-top, coacting with fixed abutments (88,89), the said clamping pieces (90) and abutments (88,89) bearing against opposite faces of the wall (86) of a hollow section (5) of the trestle (1).

Abstract: A device for transdermal administration of a drug comprises a reservoir containing the drug and a supporting strap, or band, which substantially surrounds a limb of the patient and holds the reservoir in position on a limb of the patient. The reservoir is generally non permeable to the drug, but has a membrane, or plate, of defined surface area through which said drug can pass. In use, this membrane or plate is held against the patient's skin to allow the drug to be absorbed. The device further includes cooperating locking mechanisms for detachably securing the reservoir on the strap or band whereby the supply of drug can be replenished by removing the spent reservoir and inserting a fresh one containing a new supply of the drug.

Abstract: The invention provides road planing equipment. A beam which lies substantially horizontally in relation to the ground carries a cutting unit for movement thereon. As the cutting unit moves along the beam, it planes the road surface to a controlled depth. The beam is supported at one end by a bracket which can move a frame transversely of the beam to move the beam laterally. The frame is supported on spaced, extensible and contractible legs. At the other end the beam is supported on a single expansible and contractible leg. Thus, the height of the beam above the ground and the angle of the beam in relation to the ground can be adjusted. The beam can be pivoted to an upwardly directed out of use position.

Abstract: A method of fabricating a resistor in polysilicon and a semiconductor element suitable for use as a load resistor in a static memory. In the method, after the polysilicon has been doped, the device is annealed by exposing it to a rapid increase of ambient temperature (up to between 900 and 1200 DEG C), maintaining the high ambient temperature for a controlled time (about 5 seconds) and then lowering the ambient temperature at a rapid rate. This decreases resistance by one order of magnitude and significantly decreases the temperature activation energy of the resistor. This permits static memory cells to retain data even through the cell has high leakage currents, thereby improving final test yields.

Abstract: A hand held probe unit has an infrared sensitive thermopile mounted in a metal housing kept at a constant reference temperature by a regulator circuit. A waveguide tube, surrounded by a thermally insulative probe, directs infrared emissions to the thermopile. The thermopile and regulator circuit of the probe unit are electrically connected to processing circuitry in a chopper unit. Prior to taking a patient's temperature, the probe unit is mated with the chopper unit so that the thermopile detects infrared emissions from a reference target which is also kept at a constant reference temperature by another regulator circuit. The processing circuitry repeatedly acquires the output level of the thermopile and stores calibration data. The probe unit is then removed from the chopper unit, the probe is covered with an IR transparent, disposable speculum, and is inserted in the patient's external ear canal. The processing circuitry then determines the patient's core temperature by comparing the stored calibration data to the maximum output of the thermopile during a succession of ear canal samplings.
