Abstract: ABSTRACT OF THE DISCLOSURE         An improved cased telescoped ammunition round includes a propellant charge disposed in a tubular case and having an axial bore.  The case is composed of a skin tube and forward and aft end caps on opposite ends of the tube.  The case defines a chamber that contains the propellant charge.  Separate forward and aft tubes are disposed in the case extending at least partially through the axial bore of the propellant charge from respective forward and aft ends of the bore.  The separate tubes are attached respectively to the forward and aft end cap  of the case.  A projectile is housed within the separate tubes and the axial bore of the propellant charge, and a primer is disposed within an aft end of the aft tube.  The primer is actuatable for igniting the propellant charge to cause firing of the projectile forwardly from the case.  Internal spider-like flexure springs having slightly different configurations are a associated with the forward and aft ends of the separate tubes  adjacent the forward and aft and caps and with the opposite ends of the case skin tube. The flexure springs are capable of resiliently and yieldably flexing to provide positive end cap retention during round firing and end cap retraction after firing to ensure dimensional recovery of the case after firing of the projectile so that the case can be ejected from a gun chamber.

Granted: 1992-11-24
Abstract: 54,181 ABSTRACT OF THE INVENTION A method of optimizing the handling of coincident calls in an elevator system which employs ETA strategy in assigning hall calls to a plurality of elevator cars.  The method dynamically biases the ETA value of a car having a car call for the floor of the hall call being assigned, with the bias being applied to favor assignment of the hall call to the car having the coincident car call.  The amount of the bias is inversely proportional to the car travel distance between the advanced position (AVP floor) of the elevator car and the floor associated with the hall call (scan floor).  The relative effect of the bias is predeter-mined for each floor by preselection of a constant K used in the bias calculation.

Abstract: ABSTRACT OF THE DISCLOSURE     A device  embodying  the  invention  for  a packet  time-division switcher comprises essentially a circuit for detecting beginnings and ends  of  load interruption periods  in  the switcher,  and  a  period counter. The detecting circuit is connected to a plurality of input buffer queues of the switcher and detects a load interruption when all queues signal a state of packet emptiness. A time base of the switcher is inhibited  at  the  end  of  a  period  of  predetermined  duration established by the counter and following the detection of a load interruption. Said duration is predetermined so as to complete the switching of a packet that has been begun.  Once the time base is inhibited, the operating of the switcher is interrupted and its power consumption becomes very low.  The time base is freed as soon as a packet is received by the queues, and the switcher resumes operating.

Granted: 1993-04-06
Abstract: AVR          Burner for wood logs Summary The burner is intended for combustion of wood logs or other similar solid fuels. The burner which will be called the basket burner is shaped as an open inclined basket (1) comprising a bottom plate (3) and a backing plate (4) which are inclined towards the horizontal plane, respectively the vertical plane, so that the connection between the bottom plate and the backing plate constitutes the lowest part of the basket. The backing plate forms a chute or hold for the package of wood logs. The two plates contain holes for air The fuel is piled up against the backing plate and is supported by the bottom plate so as to form a compact bundle of parallel wood logs with minimized surface/volume ratio.    The design of the basket burner makes the wood logs serve as efficient supporting burners for each other. Thanks to the shape of the basket burner the burning wood logs are successively brought towards each other and towards the lowest part of the basket burner during the combustion.          At the end of the combustion there remains an upright layer of burning char which radiates heat towards the space in front of the fireplace which facilitates rapid lighting of a new charge of wood.

Abstract: Abstract A method for translating a virtual address into a physical address, in which page tables used in the translation process are referenced by virtual addresses. Typically, a translation mechanism includes a translation buffer that, given a virtual address, can sometimes provide the corresponding physical address.  A translation-buffer miss is said to occur when the translation buffer is presented with an address for which it can not provide the translation.  When such a miss occurs, the translation mechanism obtains the translation by reading the page tables.  When the translation mechanism attempts to read the page tables from virtual memory, a second-order miss can occur.  The difficulty of infinite recursion of misses is avoided by handling second-order misses differently from first-order misses.  When a second-order miss occurs, the translation mechanism uses a prototype page table entry and the virtual address of the page table entry to produce a physical address without using the page tables.  Since consecutive pages of the page table in virtual memory reside in consecutive page frames in physical memory, a virtual address in the page tables can be translated to a physical address by adding the page frame number from the prototype page table entry to the virtual page number in the virtual address.  The prototype page table entry contains a page-frame number that is equal to the page-frame number of the first page of the page table minus the virtual-page number of the first page of the page table.

Abstract: This invention is directed to a useful improvement in a capacity control valve for use in a fluid compressor with a relatively high pressure HP and a relatively low pressure LP for changing the operational characteristics thereof by using the relatively high pressure HP taking into consideration such an observation that an increased pressure losses of the refrigerant as generated from an increased flow rate thereof and the thermal load on the car cooler would occasionally occur on the part of the relatively high pressure HP during the operation.  This improvement is, as summarized in brief, concerned with a capacity control valve of the type operative to take the intermediate pressure AP, for the control of a specific amount of compressed gas to be bypassed to the suction side of the fluid compressor, as a linear function of said relatively low pressure LP using a differential pressure between the relatively high pressure HP and the relatively low pressure LP of the fluid compressor; which comprises an adjusting means adapted to adjust the intermediate pressure AP in such a manner that the relative low pressure LP is made lower as the relatively high pressure HP becomes higher, and that said relatively low pressure LP is made higher as said relatively high pressure HP becomes lower.

Abstract: ABSTRACT OF THE DISCLOSURE      The improved flue gas desulfurization process is effective for removing sulfur dioxide in the flue gas with a lime-bearing material in a fluidized lime reactor (50, 110, 164, 426).  The effectiveness of the process is due primarily to the presence of sulfur trioxide in the gas, the sulfur trioxide being generated in a catalytic convertor (40, 156, 41a) and a bypass circuit (20, 408) transmitting a portion of the flue gas past the catalytic convertor (40, 418). Sulfur trioxide may also be directly injected by duct injection in order to enhance the removal of sulfur dioxide from flue gas in the fluidized lime reactor (110, 164).  In the initial phase, the duct injected sulfur trioxide efficiently raises the temperature of the lime-bearing particles (7) from the exothermic reaction with lime, resulting in the establishment of the steep temperature and sulfur oxides gradients which induce an autogeneous conversion of sulfur dioxide to sulfur trioxide.  The converted sulfur trioxide is rapidly removed by the lime-bearing particles (7).  Sulfur oxides can also be removed by injecting lime-bearing particles that are consider-ably hotter than the surrounding gas in the reactor. The improved desulfurization process greatly reduces the capital investment and operating costs of the process, and maintains a high sulfur dioxide removal efficiency while producing a useful by-product.

Abstract: For simpler and more flexible input of information into computer systems with secure signalling via input devices with secure signalling, in which, for verification, displays with secure signalling and command-enabling keys with secure signalling are operated, according to the invention it is proposed that the input device is divided into a part with secure signalling and a part without secure signalling which is connected in series before it, that all information passes through the insecure part, whether input via it or processed into commands, and that all information and commands are automatically tested in the part with secure signalling for secure signalling relevance. If they are not relevant to security, they are passed directly to a control logic unit of the system, and the additional command security procedure is only required if they are relevant to security. A particular advantage is that modifications of the input and output processes can be implemented while minimising the part with secure signalling, using modifiable devices with insecure structure, without requiring additional testing. <IMAGE>
