Title: Ribbon drive arrangement for a printer
Inventor: BABCOCK DAVID HINMAN
IPC: B41J33/16
Filed: 1982-06-02
Abstract: Apparatus for advancing equal increments of ribbon to a take-up rell (10) utilizes a drive blade (24) having an edge (26) that tends to slip in one longitudinal direction and grip in the other. Reciprocation of the drive blade at the circumference of the accumulated ribbon results in incremental ribbon movements in the direction corresponding to gripping of the drive edge. For a preferred implementation, the drive edge has the contour of an involute. By so contouring the drive blade, the engagement of the ribbon circumference is essentially tangential for a broad range of diameters of the accumulated ribbon.

Abstract: A control device for an electrostatic dust separator (10, 11) intended to control in relation to the recorded level of direct current (104) and direct current voltage (102) in the dust separator and with the help of the supply voltage (6a) passes through the zero point the switching in and/or out of the rectifiers (8, 8a) wired into the power supply lead (6a) to the dust separator, usually in the form of two thyristors. The recorded value for the current (104) and the recorded value for the voltage (102) together with the information in respect of the passage through zero of the supply voltage (100) are connected directly via conversion circuits (25, 26) to a data processing unit (112). This (112) is so arranged that in relation to the value (102,104) of the actual direct current and direct current voltage in the dust separator and with reference to the passages through zero (100) it will on the one hand calculate a specific time interval for the switching in and/or switching out of the rectifier (8) from the power supply and on the other hand generate switching-in and switching-out pulses (112a, 112b). These switching-in and switching-out pulses are fed directly, via adapter circuits, from the data processing unit.

Abstract: A method is disclosed for separating alpha-1-proteinase inhibitor from a blood plasma fraction particularly from the Cohn fractionation scheme. An aqueous solution of the blood plasma fraction is held at a pH of about 6.5 - 8.5, and a temperature of about 2 - 50° C for a period of about 0.2 - 24 hours and then mixed with a poly-condensed polyglycol. The mixture may be held at a temperature of about 2 - 10°C for a period of about 1 - 24 hours. Next, the pH of the mixture is adjusted to selectively precipitate unwanted proteins from the solution of alpha-1-proteinase inhibitor which is separated from the solution and purified further. The amount of poly-condensed polyglycol and the pH of the mixture are selected accordingly.

Abstract: An improved method and apparatus is disclosed for adding fluids to, or removing fluids from, a body part or organ of an animal which minimizes animal trauma and permits rapid, easy, repeated fluid or low viscosity gel transfers. The apparatus includes a tubular fluid-conveying element adapted for fixed connection to the animal, along with a flexible fluid conduit connected between the element and a specific internal body part or organ, such as a cow's uterus. In use, a syringe is employed to introduce or remove fluids from the body part, through the tubular element and connected conduit. The invention is especially adapted for introducing and recovering cell lines producing monoclonal antibodies or other biologically active products in large mammals, and facilitates monitoring of antibody production as well as administration of nutrients to enhance cell line growth. In preferred monoclonal antibody production procedures, the cells are initially educated through in vitro contact with ambient fluid of the selected organ (e.g., allantoic fluid from a pregnant host), whereupon the educated cells are inoculated and allowed to incubate in the host. It has been found particularly advantageous to employ the allantois of a pregnant mammal for antibody production, and some or all of the cell incubation period therein should occur after the onset of immunocompetency of the fetus.

Abstract: A fifth wheel hitch (2) includes a kingpin locking mechanism having a pair of pivoting locking jaws (3, 4) which form a socket (5) in which the kingpin (6) is retained. An adjustment device (44-48) varies the angular position of the closed jaws to vary the side-to-side dimension (53) of the socket, and thereby compensate for side wear in the hitch. A stationary, semicircular bearing (8) is fixedly mounted in the hitch and has a portion (61) forming a portion of the forward half of the socket, such that pivotal adjustment of the closed jaws also varies the fore-to-aft dimension (53) of the socket, and thereby compensates for end wear in the hitch.

Abstract: Clock-controlled dual slope voltage to frequency converter has an integrator supplying a charging ramp to a threshold detector. The slope of the ramp depends on the input voltage to the integrator and the threshold detector is triggered by the ramp to enable a pulse from a clock to generate a constant current discharge pulse. The discharge pulse is fed to the integrator to produce a discharge ramp back below the threshold. The frequency output is taken from the output of the threshold detector to be synchronous with triggering of the detector.
