Abstract: Abstract of the Disclosure A linear motion device intended particularly as the elevating mechanism of a medical examination table consists of four parallel rack members on one relatively movable part each engaged by a respective pinion carried by the second relatively movable part.  The pinions are mounted in pairs on two parallel shafts, the two adjacent pinions on the two shafts being adjacent the same support member mounting the shafts.  Stabilising means comprise two meshed pinions each of which meshes with a respective rack rigidly mounted on the second movable part as far as possible from the first-mentioned pinions.  A pair of rollers spaced from the meshed rollers engage another rack member for stabilising action at right angles to that provided by the meshed pinions.

Abstract: METHOD AND APPARATUS FOR TEMPERATURE PROBE   COVER WITH PROVISION FOR SANITARY DISPOSAL            ABSTRACT OF THE DISCLOSURE       A probe cover incorporating an inner sheath with a probe end engagement section. The section comprises a reduced width of the inner sheath adjacent the end opposite that into which the temperature probe is inserted. The reduced width section is produced by bonding of the layers of the sheath together with graduated bond strength so that with a combination of bond separation and material stretch good contact and retention of the probe end is insured. A tapered welding head in association with a resilient platen is utilized to obtain the graduated weld section. When the temperature probe is removed after use the inner sheath is turned inside-out so that the contamination of the inner sheath is contained inside the inverted sheath and cannot contact the users hands.

Abstract: ABSTRACT OF THE DISCLOSURE       Reconsolidated wood product and process for forming the product.  The product is formed from at least one flexible open lattice work web of naturally interconnected wood splinters generally aligned along a common grain direction.  The splinters are not, however, completely discrete, but remain somewhat interconnected.  The web is consolidated by compression whilst substantially maintaining it with splinters aligned along the common grain direction.  Bonding of the splinters is then effected to hold them in juxtapositions assumed to pursuant to the consolidation. The formation of the webs may be effeced by partial crushing techniques.  The fact that complete splinter-ing to avoid  production of discrete wood splinters is avoided facilitates handling and avoids the necessity for re-orienting the splinters where an oriented grain product is required.

Abstract: APPARATUS AND METHOD FOR SUSTAINING     THE OPERATION OF HID LAMPS     ABSTRACT  OF THE DISCLOSURE          To prevent high-intensity-discharge (HID) lamps from extinguishing for prolonged periods due to a power interruption or an appreciable drop in line voltage, a rectifier-battery combination provides standby power for operating a high-frequency inverter.  The output of the inverter connects to the HID lamps through impedance means which passes a greatly reduced high-frequency current as compared to the normal lamp operating current, in order to sustain the operation of the lamps at a very reduced power level.  Upon restoration of the normal line voltage, the lamps again operate with normal power consumption.  The same wiring can be used for both the normal lamp operating current and the high-frequency sustaining current or separate wiring systems can be used if desired.  The high-frequency current can be supplied simultaneously with the normal operating current or the high-frequency current can be supplied only during periods of power interruption.  In the latter case, the high-frequency sustaining current is continued for a period of at least 0.1 second after restoration of  the normal line voltage to prevent the HID lamps from extinguish ing.

Abstract: CABINET DRAWER RESTRAINER                            ABSTRACT                A resilient restraining member for use with a cabinet having a drawer.  The cabinet includes a rail integral with the drawer, a run secured to the cabinet and transport means secured to the drawer.  The resilient restraining member has a first spring portion at one end adapted to be attached to the run and a second spring portion at the other end adapted to normally extend into the run.  The transport means is disposed to travel along the run and to urge the second spring portion out of its path of travel as the drawer is moved toward a closed position.  The second spring portion thereafter returns to its normal position extending into the run to cooperate with the transport means to releasably retain the drawer in the closed position.  The transport means again is disposed to travel along the run and to urge the second spring portion out of its path of travel as the drawer is later moved toward an open position.  The resilient restraining member prevents unintentional movement of the drawer from the closed position to the open position.  The cabinet or its environment can therefore be moved without consequent move-ment of the closed drawer.  With these features of construc-tion, the resilient restraining member provides a cabinet drawer restrainer useful with any cabinet having a drawer.

Abstract: Abstract:      The specification discloses a method for the production of a thallium-carrying target material having a thermo-conductive support and metallic thallium electro-plated thereon.  The method involves applying an electric current in which AC is superimposed on DC between an anode made of a metal or its alloy having a lower ionization tendency than hydrogen and the eletro-conductive support as a cathode, both electrodes being immersed in a bath of an eletro-plating solution containing monovalent thallium ions in the presence of an aromatic amine and/or a phe-nol, so as to deposit thallium metal on the surface of the thermo-conductive support.  The target thus produced has a dense layer of thallium which remains intact when irradiated with accelerated particles in a cyclotron for the production of the radioactive isotope 201Tl, even at high irradiation beam currents.  Thus the yield of the desired isotope is high when the target material of the invention is employed.
