Title: Film cassette processor having reverse  inclined doctor blade
Inventor: MASON PAUL B
IPC: G03D9/00
Filed: 1979-11-06
Granted: 1982-05-11
Abstract: ABSTRACT OF THE INVENTION    A doctoring surface conformation for applicator nozzle structures in photographic film cassette contained processors by which a coating of processing fluid is deposited on exposed film strip moving in a given direction of film advancement.  The conformation includes a first doctoring surface extending from adjacent a trailing portion of a nozzle opening, when viewed in the given direction, and con-verging in the given direction toward the film strip.       Terminating by a given distance from the film strip is an edge of the first surface which enables such surface to trap particles of at least a predetermined size carried by such film strip.  Contiguous with the terminating edge is a second doctoring surface which is constructed and oriented relative to the first surface and film strip so that the processing fluid remains in constant contact therewith for providing a preselected fluid thickness above the film strip which is greater than the given distance of the terminating edge for eliminating wakes in the fluid coating caused by particles being trapped by the first surface.

Abstract: IMPROVED ACOUSTICAL WALL PANEL                Abstract of the Disclosure An acoustical wall panel has a core of a plu-rality of layers of glass fiber pressed together and having a density ranging from approximately two pounds per cubic foot at the front surface to approximately six pounds per cubic foot at the rear surface.  A plurality of cavities are formed on the front surface of the core. The front of the panel is covered with fabric, and the rear is covered with a septum to provide a barrier to the transmission of sound pressure waves.  The cross-sectional area, depth and spacing of the cavities are selected to improve absorption of sound in the intelligence range of speech while having less absorption in the lower frequency range to permit a desirable background or ambient noise to exist.  The spacing and shape of the cavities also provides a smooth, continuously changing curvature in the cavity side walls to increase the surface area and enhance the capa-city of the panel to absorb sound at flanking angles of. incidence.

Abstract: ABSTRACT       The construction described is a resistive sheet type of duct liner or duct silencer; i.e., a liner or silencer in which acoustical flow resistance is concentrated in a thin face sheet separating the flow passage and acoustical cavity rather than in an acoustically absorptive packing material filling the acoustical cavity.  The invention disclosed is means for applying inexpensive perforated facings, similar to those in a conventional packed silencer, to provide resistive sheets which are effective in terms of noise dissipation and in terms of self-noise (noise generated by flow through the flow passages).

Abstract: COMMUNICATION SYSTEM AND MEANS   FOR INTERCONNECTION OF SAME                           ABSTRACT       The present invention is directed to a manually programmable multi-channel communication network for linking  a plurality of information terminal locations, such as telephone stations, within an office building or the like to incoming communication trunk lines.  Prior art networks are either relatively complicated, having multiple panels at which manual switching may be neces-sary, or have required that connectors which are sub-jected to repeated mating cycles be made up in the field, thereby adversely affecting network reliability.  The present invention provides a relatively simple, manually programmable network whose repetively mated connectors may be factory preassembled and which network may be easily installed in the field by relatively unskilled personnel   The network includes first connectors for connection to the incoming trunk lines, second con-nectors for connection with cables communicating with the terminal locations, and conductors permanently affixed to the first  connectors and to third, relo-catable connectors.  The relocatable connectors mate with a portion of the second connectors and provide manual programmability.

Abstract: STABILIZED RECORDING            Abstract of the Disclosure A first signal to be stabilized in a magnetic record member is recorded via a head having a given maximal gap length and pole pieces of high saturation induction.  After the first signal is recorded, the magnetic record member is surface erased for stabilizing the just recorded signal.  In a preferred form, the surface erasing is performed by AC erasing via a transducer having a gap length less than said maximal gap length. The pole pieces of the erasing head need not have the high saturation induction of the first mentioned head.  After such stabilization, signals can be easily recorded and recovered from the magnetic record member by using transducers with gap lengths less than such given maximal gap length and using the normal ferrite heads having a lower saturation induction than the first mentioned heads.  The first signal can be advantageously employed as a position indicating signal in a magnetic record member, such as a storage disk or tape.  The first signal can also be used for other purposes, such as phase control for recording and in a controlled access or security system.

Abstract: "PIVOTED EXTENSION ASSEMBLY FOR DOWNSPOUTS" ABSTRACT OF THE DISCLOSURE          A downspout extension trough is pivoted by one end thereof to an inverted U-shaped boot which in turn is secured to the out-turned lower end of a downspout.  When in the "down" or extended position, water is directed away from the lower end of downspout.  When not required, the trough can be pivoted upwardly to rest against the down-spout under which circumstances the exit from the downspout is relatively unimpeded so that in the event that rain occurs while the trough is in the uppermost position, water can still be discharged from the downspout.  The boot strengthens the lower end of the downspout to support the trough and also maintains the open end of the down-spout when the trough is in the uppermost position.

Abstract: Case 771124 METERING APPARATUS FOR A FLUID INFUSION SYSTEM              WITH FLOW CONTROL STATION           Thurman S. Jess Nicholas Zissimopoulos Abstract of the Disclosure A system for infusing fluids into the human body includes a peristaltic-type metering apparatus which con-trols the flow of fluid through a disposable administra-tion set.  The metering apparatus includes a control system, which allows the volume and rate of flow of the fluid to be infused to be accurately preset by the operator.  The control system provides an alarm function in the event of malfunction of the pump or occlusion of the tubing of the administration set, and a minimum pumping rate for maintaining fluid flow through a system after the desired volume of fluid has been infused.  Novel power supply circuitry within the control system renders the system immune to power line transients, and novel bubble detector circuit provides for more reliable detection of air bubbles in the tubing.  A mechanical linkage between the pressure plate and downline flow restriction lunger of the metering apparatus provides for convenient loading of the administration set and for automatic closure of the plunger prior to use.
