Abstract: A lock which is adapted to transduce the code from a key by electronic means is constructed to resemble the form and functionality of a conventional mechanical cylinder lock. A main casing 1 houses the bolt 3, a rotatable thrower or cam for retracting the bolt, an electromechanical release mechanism which normally blocks rotation of the thrower, and a processor to control the release mechanism in response to the detected key code. The electronic reading means are located in association with the keyway 26 of a rotatable barrel 25 in a cylinder unit 19 manufactured as a separate unit from the main casing 1. The thrower and barrel 25 have respective cooperating mechanical couplings 36/37 and the main casing 1 and cylinder unit 19 have respective cooperating electrical connectors 34/33. The lock is therefore assembled by attaching the cylinder unit 19 to the outside of the main casing 1, thus establishing a rotary driving connection from the barrel 25 to the thrower and establishing an electrical connection from the key reader to the processor.

Abstract: During a method for fractional condensation of acid combustion gas components in condensers, by the addition of a peroxide solution to a suitable quantity of excess air, it is possible to avoid the disadvantages of the previously known methods. Exploitation of the latent heat energy of the combustion gasses is thus possible as the purification products become economical through a price reduction of the waste gas purification, resulting also in a reduced strain on the environment and the atmosphere. It should be possible to utilize the combustion gas after purification. In order to attain these ends a dispersed, surface-increasing filter aid suspended in the peroxide solution at a temperature of approx. 220  DEG C is added before the combustion gas enters the condenser, with the subsequent reduction of temperature in the condenser by the oxidized combustion gas to the temperature interval of 160  DEG C-140  DEG C, draining H2SO4, and to the temperature interval of 120  DEG C-110  DEG C, draining HNO3, and further to approx. 20  DEG C where other residual products condense.

Abstract: A compact ion mobility spectrometer (IMS) with increased sensitivity and resolution for detecting the composition of an unknown substance is disclosed. The IMS comprises a unitary cylindrical housing (42), inlet means (50, 57) for introducing sample gas, outlet means (52, 59) for withdrawing sample and drift gas, two high voltage electrodes, and a detector (70). The first electrode (60) is pulsed to inject sample ions through an opening located in a second electrode (67) which defines a drift region (90). The second electrode (67) is cup-shaped having an open end and is electrically biased to create a non-uniform electric field gradient across said drift region (90). The electric field in said drift region (90) is axial and radial resulting in an increase in ion drift velocity at the detector (70) and a corresponding increase in detected peak signal amplitudes thereby increasing resolution. A shorter drift region (90) and the absence of an aperture grid near the detector (70), which cause ion collisional losses, helps to increase IMS sensitivity. <IMAGE>

Abstract: A centrifuge rotor lid assembly which includes a handle which allows convenient handling of a centrifuge rotor and facilitates releasing the lid from the rotor after centrifugation. In one embodiment, the lid is provided with a lid knob and a spindle knob in a coaxial sliding arrangement. The lid knob is used to tighten the lid on the rotor body and the spindle knob is used to tighten the rotor to the centrifuge drive spindle. The upper end of the inner knob is provided with a handle which extends perpendicular to the axis of the knob. This handle is used for lifting the rotor after the spindle knob has been unscrewed from the spindle and for unscrewing the lid knob. The lower end of the spindle knob has a pin which cooperatively engages the lower end of the lid knob when the spindle knob is lifted from the rotor and is turned in a direction to unscrew the lid knob. The handle provides the necessary mechanical advantage for a person to exert sufficient torque to unscrew the lid knob without the use of external tools.

Abstract: The method by which polypeptides having residues other than the 20 common amino acids are made is established. A leader peptide sequence (SEQ ID NO: 7) and its gene are identified which induce or assist post-translational modifications of Cys, Thr and Ser in prokaryotes. The leader sequence may be used to induce the presence of covalent bonding sites in polypeptides and can be expressed by either naturally occurring or artificial means. Further, a subtilin mutant substituting isoleucine for Glu4 of the native sequence exhibits a 57-fold improvement in stability, resisting modification of the dehydroalanine residue at position 5. This stable mutant exhibits 3-4 times the specific activity, in suppression of bacterial spore outgrowth, of the native bacteriocin. A method for site-specific mutagenesis, as well as the resulting mutant gene, plasmid and transformant is similarly set forth.
