IPC: G02F1/17
Filed: 1982-10-21
Abstract: An electrochromic layer is applied to optical transmitting components, and electric-circuit connection to the layer enables temporary increase and decrease in the absorptance of the component. To increase the absorptance, a well-defined quantity of charge is supplied to the electrochromic layer; and to restore the initial condition, a well-defined quantity of charge is removed from the layer. Preferred fields of use are lenses, particularly eyeglass lenses, filters, and dimmable mirrors.

Abstract: Poly(ethylene terephthalate) resin and blends of poly(ethylene terephthalate) resin with other polymers are extruded while being coupled with an organic diisocyanate under conditions where carbon dioxide gas is vented smoothly, as it is formed. The extruder has a number of zones (1) to (6) designed to perform specific functions. The temperature in the kneading zone (4) and in the venting zone (5) must be maintained at about 280-320°C to bring about rapid reaction and to permit efficient gas evolution and removal without thermally degrading the polymeric material. The extruded article is free of trapped gas bubbles and other imperfections. This process is particularly suitable for making PET billets, which then are stretched to form strapping useful in packaging applications.

Abstract: A coin testing apparatus comprises transmitting and receiving coils (14) and (15) on opposite sides of a coin passageway (11). The transmitting coil is connected to high and low frequency oscillators (16) and (17). The output of the receiving coil is separated into the high and low frequency components by a high pass filter (21) and a band pass filter (22). In the high frequency channel the signal is amplitude controlled by a voltage controlled amplifier (23) rectified by a rectifier (24) and smoothed by a long time-constant circuit (26). The initial rise in level caused by a coin entering between the coils (14) and (15) is detected by an instantaneous level change comparator (32) which responds to the rate of change of signal level at the output of the long time-constant circuit (26) becoming equal to a preset threshold and causes a normally closed switch (27) to be opened. When the switch (27) is closed a comparator (31) compares the signal with a reference value from a source (30) and adjusts the gain of the amplifier (23) until the signal corresponds to the reference value. Upon the arrival of the coin the switch (27) is opened and a long time-constant circuit (28) causes the gain of the amplifier (23) to be maintained at the level before the arrival of the coin. A window comparator (33) compares the difference in voltage with voltage ranges for acceptable coins. A similar arrangement is provided in the low frequency channel but with two differences. The switch (27) in the low frequency channel is operated by the same instantaneous level comparator as is used for the high frequency channel and instead of a rectifier (24) a novel sample and hold technique is used for providing a d.c. signal from the output of the amplifier (23).

Abstract: The process comprises the cereals being delivered to a treatment room which has a plurality of trays arranged in vertical sequence and, in this room, being transferred from one tray to the next from top to bottom and being treated with a medium, in each case one layer of the cereals lying on one tray being removed and placed on the tray underneath. This process is characterised in that the cereals are kept in essentially constant vertical motion downwards, with the layer removed from one tray being placed on the other tray underneath in such a way that the cereals layers retain their mutual relative position. This entails a thin layer of cereals lying at the bottom of the tray in each case being removed and then placed on the upper surface of the cereals layer located on the tray underneath. This results in the cereals passing vertically, without altering the layers, continuously through all stages of the malting device and, at the same time, being exposed to the aeration and drying medium on the countercurrent principle. Also described is a device for carrying out the process, in which a slide device is located directly on the bottom of the tray and cooperates with the latter for continuous removal of layers of the cereals. The slide device is integrated in the bottom of the tray to result in tray modules which are repeated in essentially all stages from the steeping stage to the cooling stage. <IMAGE>

Abstract: An apparatus for unstacking or destacking sheets of material from a stack of such sheets is disclosed. The apparatus includes an arrangement for directing air against the stack of sheets in order to entirely separate at least one uppermost sheet of the stack from the remaining sheets by floating that sheet on a layer of air. A pusher mechanism is provided for moving the separated sheet out of registry with the remaining sheets, and into a roller mechanism which displaces the separated sheet from above the remaining sheets of the stack. The apparatus also includes an indexing mechanism for indexing the stack of sheets upwardly in order to float the next sheet of the stack and present it to the pusher mechanism. A sensing mechanism is provided for determining the position of the uppermost one of the remaining sheets of the stack as the stack is indexed upwardly. Notably, the apparatus can be used for destacking sheets of a wide variety of materials, and is operable at a relatively high speed with minimal scratching, marring, or other damage to the sheets.

Abstract: The invention concerns a process for the preparation of nitric acid esters of organic hydroxy compounds by reacting an organic hydroxy compound with nitric acid in the presence of sulphuric acid and in a solvent, followed by separating off the spent acid, substantially neutralizing the residual acidity of the organic solution, and removing solvent to leave the organic nitrate. From 95% to 220% of the stoichiometric requirement of nitric acid for complete nitration is used. The mole ratio of water to sulphuric acid at the end ofthe reaction is from 0,2:1 to 2,5:1. From 200 to 2000 ml of solvent per mole of hydroxy group is present. Yields of at least 92% are obtained. The invention is particularly suitable for the preparation of alkyl nitrates, alkylene or polyalkylene glycol, monoalkyl ether mononitrates, alkylene or polyalkylene glycol dinitrates, diol nitrates, nitrates containing homocyclic or heterocyclic rings, or nitrates derived from polyols.
