Abstract: TRANSACTION EXECUTION SYSTEM WITH              SECURE DATA STORAGE AND COMMUNICATIONS                    Abstract of the Disclosure A transaction execution system includes a host data processing system having a multiple account data base and a plurality of trans-action terminals in communication with the host.  The terminals each include a keyboard, a display, document handling subsystems, a hard-ware control subsystem, a communication subsystem and a programmable control subsystem supervising the other subsystems.  A user initiates a transaction request by inserting a card into one of the terminals. After reading acceptable account identification information from the card the terminal requests entry of a pre-assigned personal ID number through the keyboard.  The ID number is encrypted by the terminal at least once and communicated to the host along with information read from the card and entered via the keyboard.  The host accesses from its stored data base an encrypted ID number corresponding to the received card information and makes a verification comparison of the stored encrypted ID number with the encrypted ID number received from the terminal.  By requiring the entry of a nonencrypted ID number at a terminal while storing only encrypted ID numbers at the host, the correspondence between credit card account information and ID numbers need be known only to a few key personnel having access to both the encryption algorithm and a particular key therefor.

Abstract: ABSTRACT OF THE DISCLOSURE      An automatic number identification system in a tributary office having simultaneous dual operation for high traffic capacity.  A pair of identifiers operates in a tributary office through a common directory number network to simultaneously identify two calling stations.  Each of the identifiers, having been seized by a trunk circuit requiring calling number ident-ification, initiate a program which applies an identification pulse through the local switching equipment to the sleeve lead of the calling line.  The pulse is of relatively short duration compared with the program time.  The first of the two identifiers to generate its pulse inhibits pulse generation in the outer identifier during the period of the program when the first pulse is traversing the common number network and the first identifier is detecting and storing the directory number significance of the pulse.  When the line associated with the first pulse has been so identified, the second identifier is released to generate another pulse for application to the sleeve lead of the calling line associated therewith.  Both identifiers then proceed sim-ultaneously to complete their respective identification programs and transmit the calling numbers to the toll center via the connected trunk circuits.

Abstract: ABSTRACT OF THE DISCLOSURE      A method of heat-treating a metal film for use as a resistor and the resulting product.  The method involves heating the film in an oxidizing atmosphere for forming a protective oxide film on the metal film, removing adsorbed foreign elements therefrom, and changing the crystal structure thereof, and for a time sufficient to change the initial temperature coefficient of resistance to a desired value.  The temperature for the heating when the coefficient is to be changed in the positive direction is a temperature in the range between the first and second critical temperature for heat treating in and above the third critical temperature.  When the coefficient is to be changed in the negative direction, the temperature is between the second and the third critical temperatures for heat treating in air.

Abstract: INTERNALLY REINFORCED LOAD CARRYING MEMBER                        ABSTRACT     A structural member primarily intended for the horizontal and vertical load carry members of industrial storage racks.          The member is hollow and has an internal reinforcing web extend-ing across the interior in the plane of the maximum anticipated bending stress and abutting against the walls of the member.          The walls on each side of the web are so formed as to provide a pair of opposed channels or grooves on the inside of the member which receive the edge of the web and provide lateral support therefor to prevent the web from buckling sideways under bending stresses in the plane of the web.  These edges are preferably spot welded to the walls of the member.  When the member is to be used in a storage rack, it is preferably generally rectangular in cross-section with the corners facing the front being angled at approximately 45° to the front surface of the member for a distance o  at least one half of the total width of the member so as to deflect mis-aligned articles being placed onto the shelves of the rack.  Openings for receiving locking pins on brackets supporting the horizontal load supporting bars are located in the side walls of the posts but spaced substantially from the front and back walls of the post so as to effect a minimum weakening of the members.

Abstract: ABSTRACT           This invention relates to a method of incorporating a gas in a candy glass.  The incorporation or mixing of the gas takes place in a vessel containing hot candy (sugar) melt under superatmospheric pressure.  The melt is stirred within the vessel using a rotatably mounted shaft with paddle blades attached to it and is mounted on the vertical axis of the vessel.  Said shaft has a hollow interior with sidewall openings at each end.  The level of the melt in the vessel envelops the paddle blades and the lower opening of said shaft.  Thus, when the gas is introduced at the top of the vessel, it enters the shaft at the top opening and exits at the bottom opening and is dispersed within the melt by the rotating paddle blades.

Abstract: Abstract of Disclosure This invention concerns the preparation of oxirane compounds by the vapor phase cracking of hydroxyesters in the presence of a basic material. Specifically, it has been discovered that the aforesaid reaction may be carried out without the prior separation of vicinal glycols, vicinal diesters or both.  This is particularly advantageous because vicinal hydroxyesters are frequently formed in combination with these latter materials and the separation thereof is most difficult. Preferably, mixtures of the hydroxyesters,   glycols and diesters are first hydrolyzed or esterified in order to increase the hydroxyester content.

Abstract: CONTIGUOUS CHANNEL MULTIPLEXER            ABSTRACT OF THE DISCLOSURE         An improved multiplexer especially adapted for combining a plurality of microwave signal channels for trans-mission over a common transmission path is disclosed.  A single "directional filter" multiplexer structure is utilized to combine contiguous or adjacent channels without resort to odd-even channel separation or additional equalization and/or compensation networks.  By purposely extending the bandpass characteristics of preselected channel filters so that either or both of their cutoff frequencies extend substantially past their associated channel band edges and well into the reflection loss regions or the adjacent channel or channels the adjacent channel mutual interaction effect is exploited.  The resultant interaction between the transmission characteristics of one channel and the reflection characteristics of the adjacent channel yields an overall transmission characteristic for each channel which meets the multiplexer loss, loss slope and group delay requirements while minimizing the need for equalizing or compensating devices.

The loop cable is preplaced in a stringing block supported in the area through which it is desired that the pulling cable pass, with the loop cable ends passing from the serving block in a single loop to the catcher.
