Abstract: A static type semiconductor RAM device comprising a latch circuit (RA) with a large drive capacity at every column which detects, amplifies and temporarily memorizes a read- out signal from each of the memory cells (MC) in the corresponding column. Each of the memory cells is small and has a low drive capacity, and therefore is used only to hold information, while data bus lines are driven by the latch circuits having a large drive capacity. This avoids reducing the read-out speed and the reliability of readout data of the static type RAM device with a large memory capacity.

Abstract: An improved method is provided for detecting endotoxins in blood serum and/or plasma, particularly human blood fractions. The method employs king crab amebocyte lysate, preferably Limulus amebocyte lysate, in the presence of a substrate which has a selected colorimetric indicator bound to it. The indicator is capable of being split from the substrate by an enzyme which can be generated in the lysate by endotoxins in the blood. Thus, the endotoxins convert proenzyme in the lysate to the enzyme which effects the splitting off of the colorimetric indicator from the substrate. The endotoxin concentration in the blood can thus be determined colorimetrically, that concentration being proportional to the concentration of color indicator split from the substrate. The blood sample need not be extracted, as is required in prior methods, with a solvent such as chloroform to remove inhibitors therein which would interfere with a lysate gelation reaction. Heparin is utilized in the present method in a concentration sufficient to stabilize the lysate against loss of potency but insufficientto inhibit the reaction whereby endotoxin generates the described splitting enzyme from proenzyme in the lysate and the reaction of the enzyme to cause the split. The blood fraction need not be diluted with water and the lysate may be one which has been reconstituted from dry powder, if desired. The method is simple, highly effective, reproducible, inexpensive and rapid.

Title: Annular piston machine
Inventor: LANGMAIER JOHANN
IPC: F04C2/10
Filed: 1981-04-09
Abstract: An annular piston machine has a toothed rotor, connected in a rotationally fixed manner to a shaft supported rotatably in a housing, and an annular piston, the number of teeth of which is one greater than that of the rotor, so that displacement chambers are formed between the teeth. Furthermore, inlet and outlet channels are provided in the housing or in the shaft, and discs and at least one control disc, provided with inlet and outlet control openings and abutting laterally on the rotor and the annular piston, and a housing annulus, having projections on its inner side, the centre line of which coincides with the centre axis of the rotor and on the inner side of which rolls the annular piston, provided with cut-outs on its outer side corresponding to the projections, and having built-in play, such that the centre axis of the annular piston describes a circular movement about the fixed centre axis of the rotor. In order to increase the efficiency of the annular piston machine and to reduce the supporting force between the rotor and the annular piston in the sliding region which is not used for transmitting torque in order to reduce the wear between the rotor and the annular piston, the projections on the housing annulus and the cut-outs in the annular piston are formed by involute or cycloid tooth systems and the point of engagement between the outer tooth system of the annular piston and the tooth system of the housing annulus and the torque transmission point between the toothed rotor and the annular piston are offset into the region of a diameter line separating the induction and compression chambers. <IMAGE>

Abstract: A modified die casting process and machine utilizes a shaped and contained charge of molten metal which is formed and moved proximate the gate runner while the die halves are open. The charge is formed between the shot piston and an ejector side plunger which includes a slave driver rod projecting to engage the shot piston. By confining and compacting the charge, a charge more homogeneous and of uniform temperature is provided. When the die halves close, the shot piston further advances moving the plunger against a stop, retracting the slave driver rod and filling the cavity at the desired flow rate. The cavity is provided with one or more impact absorbing devices positioned in recesses on the parting plane of the die. Each device comprises concentric plungers driven outwardly, first to detect flow and stop the shot piston to avoid peak impact pressure, with the internal plunger then being extended independently to apply compacting pressure to the still molten core of the recess minimizing the volume of any gas trapped in the metal and to feed solidification shrinkage. Accordingly, a more time and energy efficient and less expensive machine and process is provided to obtain high quality die castings.

Abstract: A character generator which converts character code words into data items, namely column code words (C code), for controlling a dot matrix output unit, is disclosed. The character code word is presented to an address memory circuit which generates a ten-bit-long column address (CAD) that identifies the locations of the column code words within a separate data storage unit. The address memory circuit includes two memory units (PROM 1, PROM 2) which store only the first eight bits of respective column data addresses, while an additional memory unit (PROM 3) stores the remaining two bits of the respective column data addresses. A multiplexer (15) is used to select the correct two bits of each respective column data address from an eight-bit word output by the additional memory unit (PROM 3) at the same time an eight-bit address is being output by one of the first two memory units (PROM 1, PROM 2). The ten-bit address thus output by the address memory circuit is applied to the data storage unit, which may be built up by using commercially available programmable read-only memory units (PROM 4, PROM 5, PROM 6), as may the address memory circuit. For a further utilization of the storage capacity of the additional memory unit (PROM 3) of the address memory circuit, the first eight bits of additional column data addresses may be stored therein. These first eight bits are then fed to the data storage unit by way of a switching amplifier (14), with the multiplexer (15) supplementing the additional column data addresses with two bits which are zeros in order to produce a ten-bit address.

Abstract: The method allows to repeatly deflect a beam of coherent radiation for obtaining a substantial saw-tooth motion for the beam. The radiation is first polarized so as to generate a plurality of successive output elementary beams of corresponding polarization. The polarization occurs according to a sequential law whose frequency is substantially equal to the frequency of the saw-tooth motion of the beam. The output elementary beams are then deflected successively of a same given angular value according to a substantial sine law before the commutation of the deflexion to a next output elementary beam. The output elementary beams are deflected according to a same common path-way so as to generate a saw-tooth motion of the beam thereon.

Abstract: A construction assembly for making a collapsible structure has a post extending along and defining an upright post axis and having one end formed with an axially centered threaded bore open in one axial direction, normally upward. A first plate fixed on the post offset in the opposite axial direction, normally downward, from the one end extends generally perpendicular to the axis and is formed with at least one vertically throughgoing cutout offset from the post axis. A frame has a first fitting formed with a projection extending in the opposite direction through the hole and formed on the side of the first plate directed in this opposite direction with a passage that is throughgoing parallel to the first plate, and a second fitting at the one post end and formed with a projection extending in the one direction. A locking member engaged through the passage bears in the one direction on the first plate. A second plate extending generally perpendicular to the post axis is formed at the axis with a throughgoing bore and offset from the axis with a vertically throughgoing cutout through which extends the projection of the second fitting. A bolt threaded in the bore of the post passes through the bore of the second plate and has a head bearing in the opposite direction on the second plate. Thus the bolt presses the second plate down on the second fitting to lock the frame to the post.
