Abstract: A mixing and kneading apparatus with a kneading shaft bearingly supported in a cylindrical housing, a plurality of disk elements mounted perpendicularly and axially spaced apart on the kneading shaft. The disk elements carry scraper edges arranged essentially transversely to the plane of the disk elements and facing the housing wall at a slight distance. The housing wall, the kneading shaft, and the disk elements are optionally heatable or and coolable. In order to obtain an intensive intermixing and a uniform retention time of all of the product particle present in the toroidal reaction space, at least one mixer arm connected to the housing or the kneading shaft projects into the toroidal space to a distance at least in the vicinity of the axial and radial center of the toroidal cross section between two axially adjacent disk elements. The mixing arm applies a mixing and/or transport action onto the goods or products present between the inner wall of the housing and the kneading shaft.

Abstract: In a fiber-optic network having a first fiber and a second fiber, a T-connection repeater provides connection to a plurality of terminal devices. The T-connection fiber-optical repeater has converters for generating optical signals to be distributed to terminal devices connected the repeater, and redundant optical-to-electrical converters for receiving optical signals from the terminal devices. Reliability is markedly increased by including one or two mixing stars in the fiber system between the converter and the repeaters. The number of converters and supporting circuitry can be reduced by coupling more than one fiber from the star or stars to each converter. Monitoring optical-to-electrical converters can be coupled to the stars in order to detect failure of electrical-to-optical converters connected to the stars.

Abstract: The crate is made of an integral foldable blank which consists of a bottom, to which in each case opposite end and side walls are attached, of which the side walls each bear at their upper longitudinal edge a perforated plate provided with recesses for the positionally secure accommodation of containers or the like. The perforated plate has a width corresponding to approximately half the width of the bottom and lid support tabs which are folded downwards, are punched from one of said recesses in each case and are bonded to attachment strips which are punched out of the bottom, are bent upwards in opposite directions and lie parallel to the side walls. In order to improve the rigidity, it is proposed that in each case two attachment strips, together with the lid support tabs bonded to their inside, form a hollow support web, which tapers conically upwards in cross-section, between the perforated plate and the bottom.

Abstract: Bacteroides gingivalis frequently has been implicated in adult pepriodontitis. The present monoclonal antibodies are specific to Bacteroides gingivalis. The present monoclonal antibodies are typically employed as a reagent which includes an inert carrier, preferably a liquid such as buffered solution and a preservative. The carrier compositions are suitably selected to provide for the proper dispersal of bacteria, and to preserve the integrity of antigens and supplemental structures. The selection of the proper carrier is especially important in the detection of bacteria which produce large amounts of autolytic enzymes such as B. gingivalis. The monoclonal antibodies of the present invention are useful in clinical testing and differentiating antigens in the gingival or subgingival sera. The method of testing and differentiating involves the steps of contacting a sample of the bacterial flora from a lesion or other site with a measured amount of a monoclonal antibody specific to a single antigen site or Bacteroides gingivalis and subsequently measuring the number of antibody-antigen complexes formed.

Abstract: To join two pipes (1,2) of heat fusible material, an expansible sleeve (4) slid into one of the pipes (1) until it contacts a heater plate (3) between the adjacent ends of the pipes (1,2). The heater plate (3) then heats the ends of the pipes (1,2), and is removed. Then the sleeve (4) is slid so as to overlap the two adjacent ends, and expanded into contact with the inner surfaces of the pipes (1,2). The ends of the pipes (1,2) are then forced together so that they fuse. The sleeve (4) prevents or limits formation of a bead within the pipes (1,2) at the join. An outer sleeve may also be provided around the join to limit the formation of an outer bead. The sleeve (4) is preferably a split cylinder expanded by an inflatable bag within the cylinder.

Title: Drive apparatus
Inventor: HAKLUYTT PIERS DAVID
IPC: H02P8/18
Filed: 1987-08-25
Abstract: Drive apparatus, particularly for a twin polygon thermal scanner, utilises a stepper motor driven by pulses of variable width timed, relative to the rotational position of the motor, so that the pulses are substantially centred on the maximum torque position of the motor. This minimizes power consumption. The control circuitry for the motor performs a start sequence, which is aborted and reinitiated in the event that the motor fails properly to start and in which the frequency of the pulses applied to the stepper motor is increased as the motor accelerates. Any excessive increase in the rate of increase of frequency of the pulses is detected and corrected. When the motor is running up to speed, the power applied to the motor is controlled by a phase detector which detects variations in phase between a reference pulse train and a pulse train generated by the rotation of the motor.
