Title: Packet-switching exchange and input converter unit therefor
Inventor: BOTTLE DIETRICH
IPC: H04L49/111
Filed: 1989-11-15
Abstract: Abstract Packet-Switching Exchange and Input Converter Unit Therefor To reduce the loss of data packets, it is known to pro-vide buffers, priority logics and traffic-metering de-vices. All this must be present in each switching stage, in most cases once per input line.            This complexity within the switching network is to be reduced.            According to the invention, the incoming packet streams are converted into synchronous TDM data streams in which tine slots and individual calls are    associated with one another. Switching can then be effected using synchronous time-division multiplexing. The switching network is simpler in con-struction but must be slightly oversized.            (Figure) D. B?ttle - S.

Title: Finger mouse computer input device
Inventor: SELBY HOWARD W III
IPC: G06F3/0338
Filed: 1989-12-11
Abstract: Abstract A computer input device similar to a "mouse" which may be embodied in a single keyboard key switch mechanism with a key cap that is displaceable within horizontal plane with one finger.  Displacement of the key cap results in similar directional movement of the cursor on the computer display;  greater directional force applied to the key cap results in increased velocity of movement of the cursor on the computer display.  Pressing down on the key cap activates an electric switch which corresponds to the or "click" of a conventional "mouse" computer input device.

IPC: E04G23/02
Filed: 1990-06-07
Abstract: ABSTRACT            The invention relates to designing and construction process for raising the height of old buildings. It is suitable for use to raise the height of old buildings of 2-6 storeys, or of 7-9 storeys if necessary, with this method, it is possible to add 5-8 storeys to the old building with no need to demolish the old building and to move the residents to other places.  Owing to the employment of supporting frame structure, which is independent of and directional pivotally connected to the original building, the weight of the new building is not borne by the old building, and owing to the employment of "devices of shock resistance and shock absorbing for buildings" and "shock isolator for buildings", the aseismic capacity of the building is greatly enhanced.  This feasible method of raising the height of low-storeyed building of the invention solves a number of problems in relation to rebuilding buildings and avoid great waste it causes.          The present invention is also suitable for adding additional deck to an elevated highway and ? a flyover.

Abstract: ABSTRACT         This invention relates to a breathing apparatus used in diving.  The breathing apparatus is constructed from an underwater propelling device D having attached thereto an assembly consisting of a gas exchange module A containing hollow fibers (1) and having a gas inlet (2) and a gas outlet (3), an air reservoir (8) having an inlet (6) and an outlet (7), and a mouthpiece C having a gas outlet (11) provided with a valve opening only during exhalation and a gas inlet (10) provided with a valve opening only during inhalation, said gas exchange module A, said air reservoir B and said mouthpiece C being connected in series so that the inlet of each of them communicates with the outlet of another.         This breathing apparatus can exhibit improved gas exchange capability because the water around the hollow fibers (1) is easily replaced when the breathing apparatus, together with the underwater propelling device D, is moved through the water.  A portable breathing apparatus is also dis-closed which is constructed similar to the above assembly and can be carried on the back of a diver instead of being attached to the underwater propelling device.
