Abstract: HOT MELT MULTI-SECTION  HOSE HEATING SYSTEM Abstract of the Disclosure:          A heating system is disclosed for a hot melt hose having multiple physically and thermally inter-changeable series-connected heated hose sections wherein different hose sections exhibit different electrical power requirements per unit length.  The multiple sections of the hose are physically and electrically interconnected end-to-end between a pressurized hot melt source and a hot melt dispenser, such as a hand-held gun, having a trigger-controlled valve for regulating the flow of hot melt from the gun.  Each of the hose sections includes an inner, fluid impervious, chemically inert tube, preferably fabricated of tetrafluoroethylene; an electrically con-ductive multi-strand braided sheath snugly embracing the exterior surface of the inner tube and in intimate heat transfer contact therewith for supplying strength and heat to the tube; and an outer sheath of thermal insulating material surrounding the intermediate braided sheath for minimizing heat loss to the environment.  At least two of the hose sections have outer thermal insulating layers exhibiting different heat loss per unit length and associ-ated electrically conductive braided sheaths of substan-tially equal strength and flexibility, but exhibiting different electrical power consumption per unit length.          As such, when the braided sheaths of different hose construction are series-connected and a constant current from a regulated constant current power source is passed through the serially-connected braided sheaths, the temper-ature of the hot melt material within the different hose sections is maintained at substantially the same tempera-ture notwithstanding the difference in the heat loss characteristics of the thermal insulating outer layers of the different hoses.

Title: Pulse radar apparatus
Inventor: BERGMAN JAN
IPC: G01S7/32
Filed: 1982-01-28
Granted: 1984-11-20
Abstract: Abstract In a pulse radar apparatus target returns are detected, sampled, digitised per range quant and frequency analysed. The apparatus comprises a cell classification unit (5) for deriving from the spectrum range of the target returns a cell classification signal, whose logical values indicate that the target returns within a radar cell are classified, in the first instance, as first trace and multiple trace signals. In a microprocessor (12) the cells, which collectively cover one single target, are combined to form a cluster, while a signal representative of the target covered by the cluster is determined. Furthermore in the microprocessor (12) a cluster classification signal is derived, whose logical values indicate that the target returns within the cluster are classified as first trace and multiple trace signals.  The signal representative of the target covered by the cluster is read out if it is derived from target returns classified as first trace echoes.

Abstract: GRAY SCALE IMAGE DATA COMPRESSION WITH CODE WORDS A FUNCTION OF IMAGE HISTORY                       Abstract The present invention relates to a method and apparatus for compacting gray-scale image data which maintains extremely good picture quality and can result in typical images in a compression ratio of 5 to 1 and even better if a final step of arithmetic coding is used.  The method is a special application of adaptive differential pulse code modulation (DPCM) which utilizes a prediction of smoothness surrounding a current pel to determine variable length codes to convey the quantized error.  Thus, a continuously adaptive variable length code is produced which may be accurately decoded without using any further marker (code indicator) bits.  For each pel an "error bit" is generated to indicate to the decoder if the predicted quantization range is adequate. These error bits can be further significantly compressed. This method permits the use of a "zero bit" per pel mode for the data transmission (1 "error bit" per pel actually trans-mitted) and provides for the automatic detection of the particular variable length compression code utilized for transmitting the quantized error (Ey) for a particular pel. Utilizing the concepts of the present invention the inven-tors have obtained compression rates of approximately 1.5 bits per pel that produce a gray scale image at the decoding end of such a data transmission or storage system which has excellent quality (equal to 5 bit DPCM).  By adding the concept of arithmetic coding to the previously set forth method, due to the nature of the statistical distribution of said special purpose error bit patterns, a compressed data set of less than 1 bit per pel has been achieved.  This was produced from an original 8 bit per pel gray scale image.

Abstract: Abstract of the Disclosure A process for producing shell catalysts, for example, for gas phase oxidations in organic chemistry from an inert support and a shell of catalyst material encompassing said support, is described.  A suspension of the starting material for the shell is sprayed on a moving charge of the support while partially withdrawing the dispersing material, whereupon the crude material is dried and tempered.  For this purpose the support charge is mechanically moved by a gas stream injected from below while it is loosened.  The catalyst prestage containing a binder and, when required, an expanding agent is sprayed on the charge in increasing amounts from  above while the ratio of dispersing agent sprayed on to dispersing agent withdrawn remains constant.  The coefficient of thermal expansion of the prestage as a dry powder must not vary from that of the support by more than 15%.  The applied shell is consolidated by continuing the mechanical and fluidizing mixing motion.  The material is then dried in the gas, which continues to flow, and tempered, when required, after decomposing any added expanding agent.

Subsequently the printed products are again unwound from the intermediate package and joined with a successive second portion of the stream of printed products.  In so doing the products in the second portion come to lie in superimposed fashion upon  the  printed products withdrawn  from  the intermediate package.  Both of the superimposed imbricated product streams are conjointly wound-up upon a rotationally driven winding core to form a primary product package.  During exchange of the completed primary product package against a further winding core, the printed products arriving within the period of time needed for this exchange operation are again fed to the intermediate winding core which has now been emptied.  These  printed products  are  then wound-up  to  form  an intermediate product package.  Therefore,  the continuously arriving stream of products does not have to be interrupted during the exchange of a completed primary product package for a new empty winding core.
