Title: System for modifying acoustic environment
Inventor: RUSSELL JOHN F
IPC: E04B1/99
Filed: 1989-10-12
Abstract: ABSTRACT           A system for modifying an acoustic environment (10), which in an embodiment may be a recording studio, by the provision of modular absorption and/or diffusion elements (12) which can be located at the walls or ceiling of the space constituting the acoustic environment.  Each modular element (12) may be one of three types;  the first type providing variable absorption, the second type providing variable absorption in a mutually exclusive frequency range to the first type, and the third type providing variable absorption or alternatively diffusion over a broad frequency range. Each modular element (12) contains a local control means (11) to effect the variation, and an external actuation sensor (21) for manual control over each modular element (12).  There are also one or more transducers (14) and a noise source (15) located within the space which provide a determination of the actual acoustic environment.  All of the modular elements (12), transducers (14) and noise source (15) are interconnected to a remote control means (16) by a data bus (18).  The remote control means (16) comprises an I/O controller (17), a processor (24), a memory (25), an input device (20) and a display device (28).  The remote control means (16) provides for control over the variable acoustical components within each modular element (12).  In one embodiment, the remote control means (16) may be situated in the control room of a recording studio.

Abstract: A system for electronically transaction processing a large volume of documents utilizes high speed local area networks to distribute images and data related to the documents.      Connected to the high speed network are slower speed networks in which the processing takes place at workstations.      The workstations are programmed with window presentations that sequentially magnify portions of the image of the document where relevant information may be found and corresponding locations on a form generated by the workstation. System operation is controlled by distributed programs.

Inventor: BUSSAN MARC R
IPC: F25D25/02
Filed: 1989-10-24
Abstract: A mounting system for an article supporting member in a refrigerator includes first and second support members each of which is removably secured to a respective pair of studs mounted on opposite sidewalls of the liner of a refrig-erator compartment so that the height of the support members may be adjusted.  Each of the first and second support members includes a track for receiving opposite sides of a refrigerator shelf or storage bin for slidable movement therein.  The track of the first support member permits lateral movement of the refrigerator shelf; whereas the track of the second support member substantially prevents lateral movement of the refrig-erator shelf to accommodate dimensional variations in the liner of the refrigerator compartment.  Each of the studs is a dovetail stud having a rounded upper and lower edge so as to permit a support member to be pivoted about one stud when mounting the support member to the refrigerator compartment liner.  Each support member may have a single track or double tracks wherein the double tracks receive both a refrigerator shelf and a storage bin, Further, a wine rack may be mounted on a pair of studs in the same manner as a support member.

Title: Method for the manufacture of a moist mixture from plaster of paris and fibres
Inventor: BOLD JORG L
IPC: C04B40/00
Filed: 1990-02-23
Abstract: Abridgement A moist mixture  of  plaster  of  Paris  and  fibres  is produced  due  to  the  fact  that  before  mixing  with  the fibres, a considerable  quantity  of  water  is  supplied  to the  plaster  of  Paris,  which  leads  to a moisture content of the plaster of Paris of up to 22% by weight (with  respect to  the  dry  substance).   With  this  moisture content, the plaster of Paris  is  indeed  no  longer  stable  in  storage in an  unrestricted  manner;  however,  it remains free from lumps for a certain processing time and  can  be  mixed  with the  fibres  in  a  high-speed,  continuous mixer.  The moist mixture of plaster of  Paris  and  fibres  obtained  in  this way  is  intended  as  an  initial product in the manufacture of fibre-reinforced moulded  plaster  bodies,  in  particular of  fibre-reinforced  plaster  boards.  It contains the water necessary for setting in the  most  homogeneous  distribution and in a precise dose,

Title: Snap closing panel holder
Inventor: PYNENBURG ADRIAN W
IPC: G09F15/00
Filed: 1991-02-05
Abstract: An improved poster holder is disclosed which can be either wall mounted or suspended from a ceiling. The holder includes two longitudinal extruded panels each having a longitudinal C-shaped flange situated along one of the panel  edges. One flange is inserted within the other one to form a  longitudinal  interlocking hinge connection.  The panels  are movable with respect to each other in the transverse direction about this hinge coupling between an open and a closed position. The flanges are dimensioned in such a way that rotation of the panels with respect to one another in the transverse direction results in one of the flanges being elastically deformed during the first part of the motion, with the resulting stored elastic energy being abruptly released during the second part of the panel motion, thereby giving rise to the holder snapping open or closed. The poster holder formed by the interlocked panels represents an improvement over the prior art by eliminating the need for separate elements for hinging the panels together and biasing the panels open and closed.

Title: Dispenser construction
Inventor: STULL GENE
IPC: B65D47/26
Filed: 1991-03-26
Abstract: ABSTRACT    A dispenser construction having a tubular fitment member with an open end, and a stopper member having an annular wall and a side opening therein. The stopper member has a discharge passage communicating with the side opening and a discharge orifice at the end of the discharge passage. The stopper member is carried in the open end of the fitment member, and is axially movable thereon between a raised, discharge position, and a low-ered, sealing position. Sealing structures are provided on the open end of the fitment member and on the annular wall of the stopper member, and disposed above the loca-tion of the side opening thereof, to prevent leakage of liquid. Valve structures are also provided on the fitment member and stopper member, establishing communication between the open end of the fitment member and the side opening and discharge passage of the stopper member when the latter is disposed in its raised, discharge position, and for blocking communication between the open end of the fitment member and the side opening and discharge passage of the stopper member when the latter is disposed in its lowered, sealing position. The advantage of the present construction over the devices of the prior art is that simplified molding techniques can be had, without sacrifice of ease of use or reliability.
