Abstract: IMPROVED METHOD AND APPARATUS FOR THE CONTINUOUS AUTOMATIC ANALYSIS OF THE    FILTERABILITY POINT OF LIQUIDS.  PARTICULARLY DOPED DIESEL OIL    Abstract of the Disclosure A method and apparatus for the continuous auto-matic measuring of the filterability threshold temperature of a liquid such as a doped diesel oil comprising passing the doped diesel oil through a measuring circuit surrounded by a cooling liquid at a constant flow rate, providing a crystal retaining means beyond the cooled part of said measuring circuit, measuring the pressure differential before and immediately after said crystal retaining means, and providing resistance heating to said measuring circuit when the measured pressure differential exceeds a predeter-mined value and continuously measuring the temperature of said liquid immediately down stream of said crystal retain-ing means.  The switch of the device is actuated in response to the pressure differential increasing beyond a predeter-mined level which is caused by a build-up of microcrystals, for turning on the resistance heating circuit and melting the microcrystals.  The heating circuit is then automati-cally turned off when all the microcrystals have melted, by the corresponding decrease in pressure differential in the measuring circuit in response to which the device actuates the switch once again back to its initial position.

Abstract: ABSTRACT OF THE DISCLOSURE         A holder for suspending objects comprises a carrying arm and a clamp member which may be removably fastened in a prefer-ably cylindrical, usually essentially vertically upwardly directed hole of a several times greater depth than diameter.          The hole is made in a wall such as a tunnel wall or concrete wall. The clamp member of the holder consists of a resilient, generally V-shaped member with a longer and a short limb. The short limb forms an acute angle with the longer limb making the clamp member essentially V-shaped. The short   limb is extended at its outer end by an intermediate arm forming an obtuse angle with a carrying arm which has such a length and such a direction in relation to the short limb and intermediate arm that, when introducing the clamp member into a vertically upwardly directed hole with a diameter less than the length of the short limb and long enough for the longer limb to engage with the major portion of its length against one side of the wall of the hole, the short limb will be resiliently bent in a direction towards the longer limb by its engaging the opposite side of the wall of the hole at the merging portion between the short limb and the intermediate arm, whereby the intermediate arm extends down through the hole with the carrying arm to one side of the hole resulting in that, when the carrying arm is loaded with a vertical force such as the weight of an object, there is a moment on the short limb so that the contact pressure at its ends increases in proportion to the size of the load, to retain the fastening portion in the hole.

Abstract: ?73562 TITLE OF THE INVENTION:  OPTICAL CHARACTER RECOGNITION                          SYSTEM          INVENTOR              :  MICHAEL E. WILMER          DOCKET NO. L-2380 ABSTRACT OF THE DISCLOSURE     An optical character recognition system for identifying typewritten characters and converting such to standard code for transmission.  To achieve recognition of a character, the character, as it is scanned, is recorded in a corresponding array in memory and the memory address for each scan coordinate is then modified to correspond with the virtual character center.  This coordinate center of the character is derived by inspection of the scanning array in parallel with the memory storing pass to determine the two adjacent all white rows and columns bounding the character.  The coordinate center is then calculated by dividing the bounded row and column increment by two.  The recognition of the character pattern is then performed by a set of Boolean discriminants selected to achieve the highest probability of in - character hits against a lowest probability of misses.  Print fidelity, quantum misregistration and other character edge noise are filtered by selective OR-ing of test points along an axis having the highest incidence of noise.

Abstract: ABSTRACT           A railway car door of the type including a pair of pipes and cranks rotatably secured to the door.  An operating mechanism is provided for rotating the pipes and cranks and includes a shaft rotatably supported on the door with activating means in the form of a handle secured to the shaft.  A transmission means is provided which is supported on the door interconnecting the operating mechanism with the pipes and cranks.  Upon rotation of the shaft in response to operation of the activating means, a corresponding rotation is imparted to the cranks and pipes to provide a selective lateral movement of the door into and out of an opening in the side of a railway car.  The railway car is equipped to have internally projecting cargo or lading restraining members selectively attached and removed from the inside of the railway car side wall adjacent to the opening.  Filler members are provided which are removably attached to the door.  The filler members project into the car by an amount substantially equal to the internal projection of the cargo restraining members.  Means are provided for selectively increasing or decreasing the amount of rotation of the pipes and cranks possible so that when the filler members are attached to the inside of the door, the pipes and cranks can move a greater rotational distance to consequently move the door laterally out of the opening a first, greater distance and thereby permit the filler members to clear the side wall or an adjacent door of the railway car.  When the filler members are removed, the cranks and pipes are permitted to rotationally move a lesser distance to consequently move the door, without filler members attached thereto, a second, lesser distance laterally out of the opening and clear of the side wall or an adjacent door of the railway car.  Adjustable door stop means are also provided for positioning the door and for protecting the door and a second, railway car door, which may be adjacent thereto, from damage by impact with each other. The adjustable door stop means includes an adjustable door stop member selectively secured to the door in a first and a second position.  In the first position, the adjustable door stop member protects the doors from damage by impact with each other when the second, adjacent door is moved laterally out of the opening the first, greater distance while allowing the second adjacent door to move along the side wall in a direction away from the other door.  In the second position, in which the adjustable stop member is in an inverted position with respect to its first position, the adjustable door stop member is stored and remains readily accessible when next needed for protection of the filler supporting doors from impact with each other.

Abstract: Abstract of the Disclosure A catalyst regenerator is disclosed which incorporates a closed vessel having a centered stand pipe concentrically arranged within a spent catalyst distributor.   The catalyst is carried upwardly by the distributor and is scattered evenly and concentrically about the distributor.  The spent catalyst is deposited on or near top of the dense phase catalyst be.  A symmetrically arranged, preferably trianglar fresh air distribu-tor system includind a number of transverse brances having small nozzles mounted thereon forms a grid pattern below the lower portions of the catalyst bed in the regenerator   Air for burning of the coke on the spent catalyst is introduced evenly to minimize the size of the air bubbles in the dense bed.  The catalyst in the lower portions of the bed has a minimum of coke remaining thereon.  The oxygen of the air whlch is lntroduced ln the lower portlons of the bed is consumed by combustion of the reduced quantity of coke in the lower portions of the bed.   As the air flows through the dense bed to the upper surface,  the catalyst encountered at the higher levels has more coke on it. However, the air is partly depleted of oxyeen which prevents formation of excluslve particle temperatures in the dense phase fluid bed.   The region of high coke concentration experiences controlled burned achieved by controlled partial oxygen deple-tion.  This tends to burn more of the carbon in the bed, thereby reducing afterburning ln the dilute phase abovo the bed.   This provided uniform heating of the catalyst to a higher temperature, thereby reducing the heat required in the feed back pre-heater. Carbon monoxide disposal euipment is also eliminated by consump-tion of most of the carbon monoxide within the bed, all without afterburning thereabove.   A method is also disclosed.
