Abstract: ABSTRACT:         There is disclosed a memory arrangement par-ticularly intended for cooperation with a radar image dis-play unit.  the arrangement comprises a so-called "main memory" which contains the data words which are arranged in accordance with a set of addresses.  The arrangement includes an input circuit having an output connected to the data input of the main memory and also at least one input for receiving an input word intended to be written into the main memory at an input address.  This arrange-ment is characterized in that memory locations are pro-vided which are determined by the same set of addresses and a write circuit in these locations to write therein a first word at the same address, or a data word is written into the main memory and for writing therein a second word under the control of a so-called updating signal in all the addresses of the said set.  The arrangement is further characterized in that the input circuit comprises a control element to provide that during reading, at the output of the main memory of a data word accompanied by the second word, an invalidation data word is entered into the main memory at this address.

The front and rear ends of the compartments are closed by intercalary members which are displaced independently towards a stationary unstacker by means of separate conveying chains.  The intercalary members are caused by retractable catch-strips to cooperate in pairs with the conveying chains in order to form each time the front and rear ends of one compartment and to transport a corresponding packet of objects along the magazine towards the stacker.

Abstract: ABSTRACT:           For the transmission of speech data in time-division multiplex, a frame frequency of 8 kHz with fixedly assigned channels in the frame is effective, whereas such a fixed assignment is very disadvantageous for the transmission of data packets.  Consequently, according to the invention the frame is subdivided into several groups each having the same number of words, and each group comprises either exclusively narrow-band channels for the transmission of speech data or is associ-ated with the high-rate channel.  A signaling word which for groups comprising narrow-band channels always com-prises an unambiguous bit sample of, for example, the highest priority is assigned to each group.  When a sub-scriber station wants access to a word group in the high-rate channel it transmits its own address and possibly priority data in a signaling word.  When this bit sample is received without any disturbance the subscriber station immediately occupies the assigned group of words in the high-rate channel for the transmission of a data packet. Judging the priorities of individual subscriber stations can be done in different ways.  When the bit sample of groups comprising narrow-band channels gets the highest priority, these channels are automatically protected from access as a high-rate channel, and a central unit can in a flexible way increase the number of narrow-band channels by transmitting a further group of this bit sample in the signaling word.

Abstract: Abstract of the Disclosure A nonlinear optical apparatus is provided with a multiple layer heterostructure made from alternate layers of a charge carrier semiconductor material having a narrow bandgap energy, and a charge barrier material having a wider bandgap energy than the charge carrier material.  The layers are deposited one upon the other in substantially flat planes forming a series of potential barriers.  The potential barriers are capable of confining charge carriers which arise within the layers of the charge carrier semiconductor material to remain substantially therein. The optical absorption coefficient of the multiple layer heterostructure exhibits at least one sharp resonant optical absorption peak near the semiconductor material bandgap absorption.  A light source is restricted to provide a beam of light photons of energy near the energy of the sharp resonant optical absorption peak for promoting production of charge carriers within the charge carrier semiconductor material.  The light photons are directed into the multiple layer heterostructure so that the light photons may saturate the optical absorption coefficient and thereby cause the index of refreaction of the multiple layer heterostructure to vary with incident light intensity.

Abstract: FIBER OPTICS SECURITY SYSTEM                ABSTRACT OF THE DISCLOSURE     A fiber optics security system includes closed loop fiber optic link means which transfers energy from a radiant energy source to a radiant energy receiver.  The link means includes a plurality of fiber optic links and a plurality of detectors serially connected.  Cessation of energy to the receiver causes an alarm.  One detector includes an optical transducer spaced a distance from, and in alignment with, a second optical transducer such that light transmitted, through air, is received by the second transducer with insignificant loss so as not to cause cessation of energy to the receiver.  In a water medium, due to its absorption characteristics, light received by the second transducer is so insignificant that energy to the receiver ceases.  The first transducer provides a beam of light along a straight path within a medium having a constant index of refraction to the second transducer spaced therefrom and oriented along the path so as to ordinarily receive the beam of light.  When light passes through media having different indices of refraction at angles other than normal, light is refracted away, whereby energy to the receiver ceases.  The media can be the same substance with different indices of refraction, or it can be of different substances.  The two transducers are so spaced and oriented that the straight path therebetween is both other than horizontal and other than vertical.     Another detector includes optical fiber which is stable at temperatures of up to approximately 135°F but which melts at some temperature above approximately 155°F, thereby providing for fire detection by causing cessation of energy to the receiver.

Abstract: A plant for de-icing surfaces.            ABSTRACT            A plant for de-icing especially surfaces of aero-planes, comprising the use of at least two sources (10,12) of liquid media that are different from each other and capable of being sprayed separately or as a mixture, comprising a number of positive liquid pumps (16,22) corresponding to the number of media, which pumps all have the same capacity or a prede-termined interrelated capacity ratio and terminate in a common spray pipe (24). The connection of the liquid pumps to the sources includes at least one multi-way valve (28) for connecting at least one of said sources to at least one of said liquid pumps. In a hydraulic system comprising hydraulic motors (56,52) for driving the liquid pumps (16,22) at least two of said motors are connected to a common hydraulic pressure pump (32) controlled by way of pressure compensation to work with at least two pressure stages subject to a ratio corresponding to that of the capacity of at least one liquid pump to the total capacity of both liquid pumps. In such a plant the composition of the spray liquid to be dispensed is determined solely by the capacity of the liquid pumps, thereby eliminating any throttling effects which may cause the de-icing medium to coa-gulate.
