Title: Process for preparing bisphenol a
Inventor: IIMURO SHIGERU
IPC: C07C67/00
Filed: 1988-12-02
Granted: 1991-04-09
Abstract: ABSTRACT     This invention is a process for the preparation of bisphenol A from acetone and phenol.  By this invention,  the  formation of by-products is extremely decreased and post treatment steps can be simplified.       This invention involves the following steps.  (1) One mole of acetone is reacted with 4 to 12 moles of phenol in the presence of a sulfonic acid type cation exchange resin catalyst modified with a mercapto group-containing compound such as mercaptoethylamine  to convert 20 to 60% of acetone, and (2) the reaction mixture containing unreacted acetone is successively reacted in the presence of the hydrochloric acid catalyst.       The   formation   of   by-products   such   as 2-(2-hydroxyphenyl)-2-(4-hydroxyphenyl)propane, Dianin's compound and the like is remarkably reduced by the process of this invention.

Abstract: ABSTRACT               INJECTION MOLDING MACHINE               An injection molding machine comprises a main structure including a machine pedestal having a top cover, a horizontally movable clamping unit supported on said machine pedestal, and an injection unit supported of said machine pedestal. The machine also comprises a control cabinet, a manual control panel for direct control actions and an input unit, which comprises a data display device and an input key-board. The input unit is movable from a position for use to a position of rest, in which the input unit is disposed within a space that is defined by the overall dimensions of the main structure of the invention molding machine. The input unit is connected to the control cabinet by at least one cable. The manual control panel and the input unit when it is in position for use are within the reach of an operator assuming a predetermined working position in front of the machine.          Because the swivel arm, which carries the input unit, and the bottom surface of the control cabinet, which is attached to said main structure at the rear thereof, extend approximately in the plane that is defined by the top cover of the machine pedestal, and because the input unit and the control cabinet are detachably connected to said main structure to form a unit therewith, the main structure together with the input unit and the control cabinet can be handled in unison within a confined space. On the other hand, the arrangement ensures that the machine can conveniently be manually controlled and serviced.

Abstract: REUSABLE QUICKLY ASSEMBLED AND QUICKLY KNOCKED DOWN WORK SUPPORTS, USED SINGLY AND WITH OTHERS FOR MANY      PURPOSES AND CONVENIENTLY CARRIED AND STORED                            ABSTRACT    Work supports, which are quickly assembled and quickly knocked down, are used singly and with others, with and without accessories, for many purposes.  When not an use, these work supports are conveniently carried and stored.  Each work support has a pair of leg assemblies, wherein each leg has an overall planar triangular shape made of continuous pipe, arranged, via bending, with a horizontal lower pipe side for ground or floor contact, and two upstanding opposite slanting pipe sides, which are secured by welding to the underside of a larger pipe.  This larger pipe serves as a horizontal cross bar sleeve.  Each triangular planar shaped continuous pipe leg is positioned at a five degree cant with the horizontal cross bar sleeve.  Also, each leg has two short length bracing pipes, each extending on a forty five degree angle between a respective upstanding opposite slanting pipe side and the underside of the larger horizontal cross bar sleeve, and so welded, to increase the strength and to eliminate flexing of each leg assembly of each work support.          Each horizontal cross bar sleeve has a threaded hole to receive a threaded locking bolt, and non threaded aligned holes to receive a drop in depending threaded bolt, which integrally supports above an integral channel section, which is ready to receive a piece of two by four or two by six lumber, etc. at one of many selected angles.  Moreover, each work support has a horizontal pipe of selected length, or a telescoping set of horizontal pipes, which are insertable at their respective ends into respective horizontal cross bars, and locked upon turning the locking bolts to complete the basic assembly of one work support. The bottom of each horizontal lower pipe side is coated with a non-scuffing, non-slipping, and non-conducting insulating material.

Abstract: ABSTRACT    This invention relates to an method for encoding and transmitting an image.  A preprocessing step is used to generate blocks of pixels and to generate a vector signal for each block and outputs the vector signal.  A movement compensation processing step is used to generate a plurality of reference blocks to be used by a frame memory, calculate a reference vector signal, perform a distortion computation, select a block having minimum distortion and output the position information of the selected block.  An encoding processing step is used to calculate a differential vector signal, to encode the position information of the selected block, to send the encoded signal to a transmission data buffer and to encode the position information of the selected block and the differential vector signal.  A threshold value control step is used to control the threshold value under various signal values.  Finally, the auxiliary threshold control step is used to reduce the threshold value when the distance between the current input block and the selected block calculated by the movement compensation step is large.

Abstract: A sampled data treble control system, requiring a single multiplier element (22), includes the cascade connection of a first adder (20), the multiplier (22), and a second adder (24) coupled between the system input and output terminals. A subtracter (32) develops the differences between the system input and output signals and applies them to an IIR filter (26,28,30). The filtered differences are scaled and coupled to the first (20) and second adders (24). The system transfer function H(Z) is given by      H(Z) = [1+(Z-1)/(1+1/A)K]/[1+(Z-1)/(1+A)K] where A is a treble control variable applied to the multiplier (22), K is a scaling constant and Z is the conventional Z-transform variable.

Abstract: The invention concerns a method and an arrangement for generating smoke for smoke treatment of foodstuffs. The smoke is developed by means of a technique in which combustion takes place from above, the smoke being used only when there is a charcoal layer of 0.5 to 100 mm on the fuel stack, which has arisen during combustion of the fuel. The charcoal layer acts as a regulator of the combustion air flow, the combustion being allowed to take place at a temperature which is advantageous as regards the development of odours and hazardous substances. The layer of charcoal also acts as a selective filter and removes hazardous substances from the smoke. <IMAGE>
