Title: Polystyrene blocks for concrete shuttering
IPC: E04G11/46
Filed: 1971-04-23
Abstract: Shuttering, for use in laying concrete, is formed from blocks of expanded polystyrene which fits into cavities in a box-like frame. The frame consists of a board which has on one side an egg-box-like structure in which the thickness of the partitions is sufficient to stop breaking, by vibration, during pouring of the concrete. The frame has small lugs at the top and corresponding cavities at the bottom to allow stacking of the blocks, and stop sliding. The polystyrene blocks or the whole unit may be recovered and re-used.

Abstract: ABSTRACT This invention relates to a method of telecommunication, especially data communications.  The method employs plural carrier waves each of which has its own frequency in an assigned frequency ba??  A signal pulse train is divided into a train of frames, and the signal pulses which are assigned in each frame are subdivided in a specified order into subtrains of pulses each of which corresponds to its own carrier waves.  The signal pulses which are assigned into one subtrain of pulses are addressed to half or one cycle of the carrier waves within the period of tome corresponding to one frame, and the amplitude of the half or one cycle of the carrier eaves is modulated according to the value of the addressed signal pulse.  After that, all of the carrier waves are mixed and transmitted through the desired line or broadcast after modulations by conventional methods.  By means of the method, of the invention data may be transmitted at very high speed using a very narrow frequency band.

Abstract: ABSTRACT OF THE DISCLOSURE           Collagen, available from domestic animals, is freed of noncollagen proteins and glycoproteins, glycoas-aminoglycans and lipids by treatment including enzymatically treating with a proteolytic enzyme to provide a product which is soluble in dilute acidic aqueous solutions (colla-gen in solution--CIS).  The collagen in solution is then treated according to a specific regimen (under conditions where the collagen in solution slowly comes out of solution while exposed to mild shear forces) resulting in the forma-tion of a fibrous precipitate composed of regularly ordered fibers of collagen having a natural appearing ropelike structure.  These resulting aggregates are referred to as native fibrous micropolymers (NFM).  Once the regimen or procedure is completed, and the fiber mass has been formed, the NFM may be freed of salt, taken up in a different solu-tion or modified.  For example, cross links may then be introduced to stabilize the fibers.  The products find wide use as packing, membranes, fibers, bags, supports, integu-ments, and ate especially suitable for biologic implantation or application.

Abstract: ABSTRACT OF THE DISCLOSURE   A matrix transform system for coding and decoding images. The system comprises means for sampling the lines and the columns of an image and forming with these samples a sample square matrix and storing the same. This sample square matrix is splitted into component square matrices of order 3N x 3N having a central part of order N x N. Each of these component matrices is multiplied by a first rectangular coefficient matrix of order N x 3N having a square central part in which the coefficients are equal to unity and two square lateral parts in which the coefficients are selec-tively equal to zero and a predetermined factor smaller than unity, which gives an intermediate matrix of order N x 3N. This inter-mediate matrix is multiplied by a second rectangular coefficient matrix of order 3Nx N which is the transpose of the first rec-tangular coefficient matrix, which gives an output matrix of order N x N which is the tranform of the central part of the component matrix. If N = 2, the output matrix is of order 2 x 2 ; one of its terms depends on four samples of the image, two of its terms depend on twelve samples of the image and the last of its terms depends on thirty six samples of the image.

Abstract: ABSTRACT OF THE INVENTION      A system for the cyclical time-compression of a signal waveform, particularly applicable to the display of physiological waveform data from patients.  The system receives a continuous data sequence, as from an initial waveform, and continuously and temporarily stores waveform data during the trace and retrace phases (phases B & A) of a processing or display operation or cycle and which subsequently reads out substantially all of the stored data in a time-compressed form during the trace phase (phase B) of the cycle.  The rate at which data is read out of storage is uniform and faster than the rate at which it is entered into storage. Further, the compression ratio of the system is fully flexible, though from the standpoint of design convenience at least one of the integers of the ratio may be binary based.      In a preferred embodiment, the data storage is provided by a random access memory capable of storing the requisite number of data samples occurring during the retrace or blanked phase of a display cycle. Separate read and write address counters are indexed at respective different rates such that the ratio of their rates corresponds with the desired compression ratio.  The read address counter is inhibited during the retrace or blanked phase of the display cycle while the random access memory is "filled" with incoming data samples.  The inhibit signal may also synchronize or otherwise control generation of the sweep signal for a display device.

Abstract: A B S T R A C T           A thermopneumatic support device for providing sup-port over a range of positions for objects, such as high temperature steam piping, subject to temperature changes and thus to changes in position resulting from thermal expansion or contraction.  The device utilizes the heat energy of the object being supported in order to provide the necessary power to move the object over a range of positions.          The heat energy from the object being supported provides the power for moving the thermopneumatic support in direct pro-portion to the expansion or contraction resulting from the variation in temperature of the object being supported.  The device comprises pneumatic actuating means comprising a sealed chamber containing a fixed mass of a compressible fluid which is in thermal contact with the object being supported.  Pres-sure changes in the enclosed compressible fluid results in direct proportion to pressure changes of the fluid which in turn causes movement of the support mans in response to temperature changes in the object being in  supported.  There are coupling and linking means provided between the support means and the pipe and the support means and a stationary sup-port respectively.
