Abstract: ABSTRACT    A process for producing absorbent granules from sodium tripolyphosphate or disodium hydrogen orthophosphate by simultaneously granulating and hydrating the salts to full hydration.  The process produces granules which have good absorbency without the need for a drying step.  The granules can be used for absorbing liquid nonionic surfactant or other liquid components of detergent powders such as perfumes.

Abstract: Abstract of the Disclosure An improved method of casting a single crystal metal article includes providing a mold having starter, selector and article forming cavities which are connected in com-munication with each other.  In accordance with a feature of the invention, initiation of the formation of metal crystals in the selector cavity is prevented so that a single crystal of metal can grow from the selector cavity into the article forming cavity.  To prevent the initia-tion of crystal growth in the selector cavity, a layer of heat insulating material is applied over the portion of the mold in which the selector cavity is disposed.  The layer of insulating material at least partially blocks the flow, of heat from the selector cavity in a direction which extends transverse to the desired path of crystal growth. This results in most of the heat from the selector cavity being conducted along the desired path of crystal growth.

Abstract: ABSTRACT     ISOTOPE SEPARATION BY SOLAR PHOTOIONIZATION         Isotope separation, particularly separation of isotopes of lithium, is achieved by exposing a beam of atoms to radiation that selectively excites atoms of a particular isotope without exciting atoms of other isotopes of that element.  The excited atoms are ionized by solar radiation and the ions attracted to an ion collector plate maintained at a negative potential.  The atoms not ionized are condensed on a grounded atom col-lector plate.  Optionally, the solar radiation not absorbed by the system may be used to generate electricity.  Lithium isotopes are useful in nuclear reactors and nuclear weapons.

Abstract: ABSTRACT      An optical code disc includes a fine track which provides a high resolution signal, at least one V scan natural binary track synchronized to the fine track by lead and lag detectors, and Gray code tracks which provide the most significant bits of the digital output of the encoder system.  The number of circuit elements in the multiplier cir-cuitry associated with the fine track are reduced by means of a quadrant switching technique whereby the sinusoidal inputs to the multiplier are repeated through each quadrant of the fine track cycle.  The V scan and Gray code tracks are optically multiplexed to reduce the number of leads from the optical de-tector.  The use of both V scan and Gray code tracks minimizes the number of detectors required in the system while maintaining large detector signals from each track.  The V scan and Gray code outputs are synchronized by the use of an overlapping bit.

Abstract: HOLLOW ARTICLE INTERNAL PRESSURE FORMING APPARATUS AND METHOD Abstract of the Disclosure: An upper die is movable by a ram downwardly against a lower die with the dies enclosing a hollow article such as a knobshell in die cavities thereof. Ram continued downward movement of the closed dies forces a piston connected to the lower die downwardly against hydraulic fluid of a containing cylinder forcing the hydraulic fluid internally of the knobshell through the neck thereof forming the knobshell outward-ly against the die cavity surfaces. The piston size compared to the knobshell size automatically creates a reactive force reversely tending to maintain the dies closed greater than the internal knobshell forming force tending to separate the dies. After knobshell forming, reverse ram movement first relieves piston pressure against the hydraulic fluid and ultimately separates the dies with a knockout member being actuated to eject the formed knobshell. During forming, an automatic pressure relief valve maintains maximum hydraulic fluid pressure not exceeding a predetermined maximum pressure and an automatic fluid refill valve refills the cylinder with hydraulic fluid at separation of the dies for formed knobshell removal. -1-

Abstract: ABSTRACT OF THE DISCLOSURE    A display member, for example a visual display unit presents symbols which are divided into modules.  Each module consists of a dot matrix.  A refresh memory has one word for each module on the visual display unit.  Out of the words in the refresh memory, which correspond to the modules of a symbol, one word contains a symbol code and the other words define the dot matrices of the modules. Control information in each word indicates if the word is a symbol code or a dot matrix.  A code transformation memory is supplied with the symbol code and has a word at an address indicated by the symbol code, which word defines the dot matrix of the module in question.  A selector forwards to the display member, in dependence on the control information, the word read from the refresh memory if the control information indicates that the word defines a dot matrix, and forwards the word read out from the code trans-formation memory if the control information indicates that the word read out from the refresh memory is a symbol code.

Abstract: ABSTRACT OF THE DISCLOSURE A replacement hasp for a railroad sliding door lock mechanism, a kit for making the hasp, and method for making the replacement using the kit are disclosed in two embodiments.  The kit includes a member which partially def-ines an eye, sized to fit loosely about the existing hasp-retaining link on the car, and an eye-completion member arrayed to mate with the first member and form a replacement hasp when affixed thereto, as by welding with shear welds. In the first embodiment, the first member is generally U-shaped and the second member includes a tongue portion which mates between the ends of the partial-eye-defining member such that the two can be "telescoped" together to form a replacement hasp of different lengths to accommodate changes in the door or door jamb of the railroad car.  The two main members include furrows extending along the parting lines between them so as to aid in welding the main members together and to form a stronger affixture than is possible under the prior commercial practice.  The second embodiment is similar to the first but includes a keyway formed through the members and a key which may be inserted when they are mated together in their usual intended position to affix the members together.
