Abstract: A B S T R A C T     A closure mechanism for a cabinet of the type where the closure mechanism is adapted to close off the cabinet front.         The closure mechanism includes a pair of rotating doors urged to a closed position, a timer mounted to the interior of the cabinet to time the closing of the doors, and latches to latch the doors in a closed position responsive to the closing of the doors.  Links are pivotally mounted to each door, for propping the doors in an open position, the links being fashioned from heat fusible material whereby a selected rise in ambient temperature will fuse the link, thereby releasing the door from its open position and allowing it to close when the timer releases it for rotation to a closed position.  The closure mechanism also includes a latch assembly with latching rod that includes an inclined upper end that is spring biased upward to urge the inclined upper end out of an opening in one of the doors into engagement with the top wall of the cabinet by having the upper inclined end protrude through an opening in the top wall of the cabinet.

Abstract: SEMICONDUCTOR STRUCTURE AND DEVICES AND METHODS      OF MAKING SAME                 ABSTRACT OF THE DISCLOSURE           Semiconductor devices such as lasers which include a substrate with a channel therein with a clad layer overlying the substrate and filling the channel exhibit irregularities such as terraces in the surface of the clad layer which are detrimental to device performance.          These irregularities are substantially eliminated by forming the channel (14) in a surface (12) of a buffer layer (10) greater than about 4 micrometers thick on the substrate (4) and forming the clad layer (16) over the buffer layer (10) and the channel (14).  CW lasers incorporating the principles of the invention exhibit the highest output power in a single spatial mode and maximum output power which have been observed to date.

Abstract: ABSTRACT OF THE DISCLOSURE      A multi-link communication system includes a number of stations and interconnecting audio links under the control of a central computer.  Each station is addressable by the computer for connecting selected stations to a selected audio link for establishing audio communication between stations. Each station has at least one corresponding access circuit for establishing an audio connection to a selected or preassigned link, and the connection is maintained by a corresponding memory circuit that is addressable by the computer.  A group of output lines from the computer are used as select inputs to an analog multiplexer connecting a bidirectional control line to the selected access circuit for connecting or disconnecting the corresponding station and also for receiving connect or disconnect requests from the corresponding station.  In a particular embodiment, the stations include multi-link dial and dialless telephones, single-link dialless telephones, and intercom speakers in an automatic private branch exchange.  Latching relays provide audio connections for speakers and dialless single-link phones, and unbalanced analog transmission gates provide audio connections for multi-link phones.  The capabilities of each station are encoded as predefined attributes stored in electrically alterable memory, and the attributes of a selected station are user-programmable via the touch-tone dial of an administrative telephone.  Standard and priority call-ins from dialless phones and intercom speakers are identified on numeric or graphic displays interconnected to the computer via a shielded wire or shielded balanced pair conveying a pulse-width modulated binary signal.

Abstract: The deflation of the inflatable and deflatable cuff worn by a subject during automatic sphygmomanometric measurement is accomplished in unequal size decrements and principally in larger steps than 7 Torr. Each step after detection of the initial oscillations is determined in the first instance by reference to a look-up table or en equation as a function of prevailing cuff pressure. This Base Step dimension is augmented by a factor proportional to the last oscillation amplitude, the factor being increased after detection of the maximum oscillation amplitude. A valve mechanism with at least two different effective orifice sizes is used for deflation, the smaller size effective orifice being used first, to maintain control over the decrement step rate while holding the time for decrement within a predetermined limit of 8 mSec. per Torr, i. e., maintaining the rate above 125 Torr per second. The valve mechanism can consist of two valves with unequal orifice size, or it can consist of two equal orifice size valves to be used singly for providing the effective smaller orifice, or in parallel to provide the effective larger orifice. Alternatively a single variable orifice valve can be used.

Abstract: A device 1 for locking together containers stacked one on top of another has a projecting middle section 4 with bearing surfaces 5, 6 for a first and a second container and integrally formed with the middle section a first end section 2 having a flange 7 for engagement with the container corners of the first container, and a second end section 3 for insertion in the container corners of the second container. The second end section has a locking head rotatable between an engagement position and a release position and having an engagement surface 11 facing towards the middle section. The rotation of the locking head is controlled by a handle 9, which can be rotated between two outer positions and has an axis of rotation 19 proceeding from the middle section. When the first end section is introduced into a container corner, the locking element 8 is pressed into the middle section. The locking element interacts with the axis of rotation 19 so that the handle 9 is forced to assume the outer position, in which the locking head 19 is in the engagement position, when the locking element is depressed. This ensures that the locking head is always in the position for automatic coupling with the second container, when the device 1 is inserted in the container corner on the first [lacuna] <IMAGE>

Abstract: With known carrier materials in bioreactors there is frequently blockage of the reactor with microorganisms or organic compounds. The new carrier material intends to make it possible for microorganisms or animal cells to be immobilised in a high concentration without blockage of the bioreactor occurring. 
<??>This object is achieved by using as carrier material beads which, on the one hand, consist of an open-pore inorganic sintered body which has pores which pass through the inside and are open to the outside and in which microorganisms and animal cells are able to be immobilised and grow and, on the other hand, have a density and a diameter such that, in a preset fluidised bed flow, the shear forces of the beads suffice to shear off the microorganisms or animal cells growing out of the interior of the beads and/or located on the surface. 
<??>The invention makes it possible to combine the advantages of the fixed bed reactor with the advantages of the fluidised bed reactor, and to avoid the disadvantages of both processes. The carrier material is not confined to the digestion of domestic and industrial effluents, it can also be employed for the biotechnological obtaining of essential dietary substances and pharmacological substances and of fermentation products.
