Abstract: This invention is a lockable and retractable safety cap for covering the needle of a hypodermic syringe to prevent accidental needle-stick. There is a unitary cap assembly of a resiliently flexible plastic material including a hub portion disposed concentrically about a base portion of the needle and attached to the barrel, a sliding safety hub portion having a bore therethrough slidably disposed with the needle passing through the bore and extending over a point end of the needle, and a plurality of slats extending between the hub portion and the sliding safety hub portion. The slats are parallel to the needle whereby a longitudinal compressive force against the sliding safety hub portion is resisted by a longitudinal compressive resistance of the slats which must be overcome before the slats will deform and flex outward from the needle to expose the needle for use. A releasable safety latch assembly can be disposed over the slats for preventing deforming and outward flexing thereof. The preferred assembly comprises a coil spring disposed over the slats, a sliding collar carried by an outer end of the coil spring, a retaining button located on one of the slats adjacent the inner end for holding the sliding collar to retain the coil spring in a compressed state, and a release for releasing a hold on the sliding collar when the slats bends outward whereby following use of the syringe the coil spring is released and returns to an extended state.

Abstract: A bed plate for a fluidized bed defines a plurality of substantially uniformly distributed openings therein for allowing fluidizing gas to flow upwardly through the plate. The openings (22) are divided into pairs and directed and shaped so that the gas flows (24) through the openings of each pair are directed in converging relationship so as to create a resultant flow component (29), which is directed towards a discharging position of the fluidized bed. The desired resultant flow component may be obtained by properly selecting the direction and shape of the openings (22) in each pair of openings.

Detection means (25) are provided, having an input coupled to the second terminal (10), for detecting the first or the second control signal, so as to enable the recording of the videosignal representing pictures having the first or the second aspect ratio respectively on the record carrier. Viewed in time, the second control signal is such that for repeated concatenations of a first and a second time interval (T1,T2), the second control signal is present during the first time interval (T1) and is absent during the subsequent second time interval (T2), and the detection means are adapted to detect the absence of the second control signal during a time interval which is longer than the second time interval so as to enable the arrangement to switch to a recording of a videosignal representing pictures having the first aspect ratio (4:3). Further, the detection means (25) are adapted to detect the occurrence of the second control signal so as to enable the arrangement to switch to a recording of a videosignal representing pictures having the second aspect ratio (16:9).

Abstract: An automated chemical analyzer includes an automated conveyor apparatus for receiving a variety of sizes of test tubes, cuvettes, and sample tubes in a standard carrier member receivable into the analyzer. The standard carrier members may be interlocked in ranks and placed side by side in file to replicate the size and handling convenience of conventional test tube racks. However, the conveyor apparatus also provides for receipt of the carriers either as individuals for stat handling, or in interlocked ranks, or as rank and file groups for routine handling. The interlocked ranks of carriers are automatically unlocked from one another and fed along with the carriers having stat samples therein to a recirculating endless loop conveyor device which conveys the samples to at least one chemical analysis module, as well as providing a storage capacity both for samples in testing, and those samples awaiting verification of test results. Carriers with samples on which testing is completed and verified are discharged from the endless loop conveyor device into an off-loading facility which again interlocks the carriers and presents them in rank and file groups for subsequent handling like conventional test tube racks.

Abstract: RNA is transcribed from a double stranded DNA template by forming a complex by hybridizing to the template at a desired transcription initiation site one or more oligonucleic acid analogues of the PNA type capable of forming a transcription initiation site with the DNA and exposing the complex to the action of a DNA dependant RNA polymerase in the presence of nucleoside triphosphates. Equal length transcripts may be obtained by placing a block to transcription downstream from the initiation site or by cutting the template at such a selected location. The initiation site is formed by displacement of one strand of the DNA locally by the PNA hybridization.

Abstract: A two-wire constant current powered transducer (10) for detecting, integrating and transmitting an acceleration signal (50) received from a piezoelectric crystal (12). The crystal is operatively coupled to rotating machinery (M) such that rotating anomalies correlative of wear or potential failure can be detected early enough for preventative maintenance. The transducer (10) includes two stages (30, 40). The first stage (30) is an integrator which integrates the acceleration to velocity. The second stage (40) is a gain stage. The gain stage operates with a PNP transistor emitter follower to control the output DC bias level and route the integrated acceleration signal back to the control system.
