Abstract: A  device  for  holding catalyst in a  radial  flow reactor includes a plurality of catalyst containers each of which is a segment of a cylinder divided in the axial plane  thereof.   Each  catalyst container has  a  cross section  of  a size which enables the  container  to  be carried  in and out of the radial fow reactor through an opening  formed  in  an upper or lower  portion  of  the radial flow reactor, and includes a screen provided on a liquid  inlet  side  and a screen provided on  a  liquid outlet  side.  The  catalyst  containers  are  assembled together  to  form  a cylindrical catalyst  bed  in  the radial flow reactor.   The catalyst containers attains a uniform  thickness  of  a  catalyst  bed  in  a   radial direction  between  its inlet side and outlet side  over the entire height of the cylindrical catalyst bed.   One or more catalyst containers requiring checking or repair only can be taken out of the reactor.

Title: Soft sonar suspension system
Inventor: PAKKER ULRICH
IPC: G01N27/07
Filed: 1990-10-17
Abstract: An underwater transducer assembly (T) is mounted on an elongated cylindrical piston (32) received in a pneumatic cylinder (31).  One or more springs (41) normally bias the piston (32 or 90) inward into the cylinder (31) to retract the transducer assembly (T) into a sea chest (S'). Air under pressure introduced into the cylinder (31) is effective to overcome the force of the springs (41) and project the transducer assembly (T) to a position operative for scanning. Force applied to the transducer assembly (T) tends to move the piston (32) inward into the cylinder and thereby increase the pressure of the system. The transducer assembly (T) is retracted automatically if the pressure exceeds a predetermined pressure. A separate mechanical sensor is mounted adjacent to the sea chest S' to detect the presence of obstacles or debris and automatically actuate retraction of the transducer assembly (T).

Abstract: An automatic paper feeding device includes a pivotable member around which a sending-out roller and a driving shaft are pivotally supported. Positioned between a transmission gear of the driving shaft and a transmitted gear of the sending-out roller is an intermediate gear. One of the intermediate gear and the transmitted gear has a rotational load, and the sending-out roller is elevated by the force of this load toward an insert guide plate positioned in an upper portion of the feeding device. Sheets of original paper installed between the insert guide plate and the sending-out roller are sequentially separated and ejected from the feeding device by the action of the sending-out roller on the bottom sheet. With this structure, separated paper feeding is ensured, the number of necessary parts is reduced, and a cost reduction is thereby achieved.

Inventor: SENOUE MASAHARU
IPC: A61H7/00
Filed: 1992-05-29
Abstract: An air massaging device having at least one inflatable air bag adapted to be laid against a portion of the human body.  The device includes an air pump generating a pressurized air and a distributor valve which has an open position of feeding the pressurized air to the air bag and a closed position of allowing the pressurized air to be discharged from the air bag to the atmosphere in order to repeat inflating and deflating the air bag.  A single pressure sensor is disposed upstream of the distributor valve to monitor a pressure level developed on the side of the air pump.  A control circuit is included to activate the air pump on a time-period basis in order to give a desired pressure level to which said air bag is inflated.  The control circuit operates to provide one or more initial inflation cycle and subsequent inflation cycles alternated by deflating cycles of deflating the air bag.  During the initial inflating cycle, the air pump is firstly activated for a pre-determined standard inflation time period to inflate the air bag and then stops while keeping the air bag inflated for a short time interval in which the pressure level of the air bag is monitored.  In the subsequent inflating cycles, the air pump is activated for a varying inflation time period which is determined as a function of the previous inflation time period, a desired target pressure level selected by a user, and the pressure level monitored in the previous inflation cycle.

Title: Plate wall trailer
Inventor: STAFFORD BRIAN K
IPC: B62D33/04
Filed: 1992-07-30
Abstract: An enclosed trailer for towing by an over the road truck is provided having increased internal width for a given external width. The side walls of the trailer are constructed from a series of vertically extending, spaced apart, rigid plates, preferably metallic plates, and metallic reinforcing members which have an inwardly projecting, vertically extending rib that is positioned between the adjacent edges of adjacent pairs of plates.      The reinforcing members are riveted or otherwise rigidly secured to the outside of a pair of plates. Furthermore, the plates and reinforcing members are also rigidly secured to vertically extending flanges of the longitudinally extending top and bottom beams which form the juncture between the side walls and the top wall, and the side walls and the bottom wall, respectively. Because all elements of the trailer side walls are rigidly joined to the top and bottom beams, the overall strength and rigidity of the trailer is increased.

Title: System for authenticating communication participants
Inventor: SPAANDERMAN JURGEN J
IPC: H04L9/16
Filed: 1992-10-23
Abstract: Known methods for authenticating communication participants add a code word to a command signal, which code word is a crytographic function of the command signal and a key value which in its turn is a function of a master key value and a change code word. The master key value has a permanently fixed value, in contrast to the change code word which serves to change the key value. The method according to the invention makes use of a key value which is a function of at least one previous key value, the master key value with the permanently fixed value, which, once it has been discovered or leaked, substantially weakens the encryption, no longer being required. <IMAGE>

Title: Method and system for color film separation preprocess using electronic object-based choking and spreading procedures including object combining operations
Inventor: BOENKE MARKE
IPC: G06T11/60
Filed: 1992-10-29
Abstract: A computer system 100 for production of ink separations from an object-based print pre-process apparatus using a page description language. The print pre-process system facilitates creation of object spreads for any combination or configuration of objects on the rendered page. For each object on a rendered page, the computer system 100 makes use of a spread table to determine spread incidences. For each spread incidence, the computer system generates set union, intersection and difference for spreading, receiving, and obstructing objects by use of a modified Weiler algorithm. The modified Weiler algorithm creates a simplified graph of contour histories providing a visible portion of the spread object. The visible object is strokable within a clipped window set to the receiving object. The stroke color and width, set by the spread table, can be knockout print or overprint.
