Abstract: A catalyst for producing phenol consisting essentially of a nickel compound supported on a metal oxide carrier, or a catalyst for producing phenol consisting essentially of iron oxide and nickel oxide, and processes for producing phenol using either of the above catalyst.  The catalysts of the invention exercise a high conversion of benzoic acid and a high selectivity to phenol, and phenol can be produced in a high yield, particularly in a high space time yield through the processes of the invention using the above catalysts.  The above conversion, selectivity and space time yield can be improved by calcining the catalyst at 600 to 900°C.

Title: Processor chip
Inventor: OMURA JIMMY K
IPC: G06F7/72
Filed: 1991-04-08
Abstract: A processor chip for adding a first integer having a plurality of groups of bits to a second integer having a plurality of groups of bits modulo a fourth integer having n-bits. The first integer plus the second integer equals a third integer. The processor chip includes a first register for storing the first integer, a second register for storing the second integer, and feedback register for storing a feedback number. The feedback number is the two's complement of the fourth integer. A plurality a full adders is coupled to the first register and the second register, and adds each group of bits of the first integer to the corresponding group of bits of the second integer, to generate the third integer. The bits of each group are added asynchronously during a time period.   Sequentially, a second group of bits of the first integer are added to the corresponding second group of bits of the second integer. The processor chip also multiplies the first integer by the second integer wherein the full adders sequentially add each group of bits of the second integer to each corresponding group of bits of the third integer, in response to the least significant bit position of the first integer shifted right from the first register. The processor chip can exponentiate a first integer having n-bits by a second integer having m-bits, wherein the first integer raised to the power of the second integer equals a third integer. The exponentiation is preformed with successive applications of the multiplication operation.

Abstract: INFLATABLE BLADDER               ABSTRACT OF THE DISCLOSURE      An inflatable bladder is defined by two superimposed outer  sheets  of  heat-sealable  synthetic  plastic  fused together  about  their  peripheral edges.   An Intermediate layer or baffle is disposed between the two outer sheets and is alternately sealed to one and the other of the outer sheets to form air cells on the opposite sides of the inter-mediate  layer.   Each of  the air cells  is defined by an opposed surfaces on one side of the intermediate layer and of one or the outer sheets and adjacent seals which fuse together the layer and each sheet.  The seals which define the cells on one outer surface of the bladder are offset from the seals which define the cells on the other surface of the bladder.   Opposite surface portions of the inter-mediate layer are coated with a barrier layer  to prevent heat-sealing on each side of the intermediate layer oppo-site  the  seals  on  the  other  side  which  form  the  cells whereby the bladder and the cells thereof may all be formed simultaneously in one heat-sealing operation.

Title: Wireless telecommunication systems
Inventor: VANNUCCI GIOVANNI
IPC: H04B7/26
Filed: 1991-10-31
Abstract: The present invention overcomes the prior art limitations by dividing a coverage area into very small regions or cells. The inventive system can be built as an adjunct to a wired telecommunication system such as a PBX. Advantageously, because of the relatively small size of each cell, transceivers in the inventive system can use very low transmission power, compared with a pico-cellular communications system, to communicate with a fixed transceiver. In addition, because of the relatively short distance between any two transceivers are reduced and, therefore, the multipath distortion which can affect the received signals is substantially reduced.  A concomitant problem normally associated with relatively small cells is the need for a switching system which can accommodate the large amount of switching or handovers requiredto accommodate the various mobile units as they move from one cell to another. In accordance with the present invention, this problem is solved by a switching technique which is not centralized in the PBX but, rather, is effectively distributed among the individual fixed-call terminals.

IPC: D21G1/00
Filed: 1992-02-06
Abstract: Abstract of Disclosure:            In a calender or roll frame apparatus is provided for the vertical adjustment of the rolls which are journalled in bearing housings (2) and also vertically displaceably connected with the roll frame (5) via sliding supports (3) and guides (4). The connection between each sliding support and the roll frame (5) takes place via a threaded spindle (7) with a nut (8) without self-locking and also via a housing (9). The nut (8) has at its inner surface (10) a toothed arrangement (11) and the housing (5) has a further toothed arrangement (13) at its inner surface confronting the toothed end face of the nut. The nut (8) and the housing (9) can be moved relative to one another by a switching piece (14) which determines whether the toothed arrangements are meshed or disengaged. In the disengaged state the rolls can move downwards under their own weight. For the vertical adjustment of the rolls (1) a respective stroke element (6) is associated with the bearing housings (2) of the lowermost roll (1) or with the threaded spindles (7). The arrangement permits the roll spacings to be simply and rapidly increased and also restored again after exchanging one roll for a roll (1) of different diameter.            (Fig. 1)

Filed: 1990-05-30
Abstract: In an air bag unit (1) for protecting an occupant of a vehicle by inflating an air bag (3) with the gas supplied from an inflator (2) in an emergency, a flameproof cloth (10) is provided to cover the portion to mount the inflator where the reinforcement cloth (7) of said air bag (3) is sewn and where high pressure gas from the inflator (2) directly hits. As the result, hot gas blown out of the gas blowing holes of the inflator (2) directly hits the flameproof cloth (10), and the portion where the reinforcement cloth (7) of the air bag (3) is fixed is not brought into direct contact with hot gas immediately after blown out because the flameproof cloth (10) serves as a shield. Accordingly, the melting of the sewing threads (8 and 8') fixing the reinforcement cloth (7) or the adhesive agent can be avoided. Further, the reinforcement cloth (7) is perfectly fixed on the air bag (3) when the air bag (3) is inflated and expanded, and the air bag (3) can be further strengthened.
