Title: Retaining a part within a business form
Inventor: ASHBY ROBERT E
IPC: B41L1/32
Filed: 1990-12-28
Abstract: ABSTRACT OF THE DISCLOSURE      A mailer type of business form having a carbonizing bond sheet with a carbon spot on one face, and an insert, is constructed so that the carbonizing bond sheet will remain within the outgoing envelope when the insert is removed.  This is accomplished even though the carbon spot goes all the way to the end of the carbonizing sheet by providing thumb notches in the outgoing envelope plies and the carbonizing bond, but not in the insert.  The carbonizing bond is stream pasted to the interior top ply-of the outgoing envelope to maintain it within the outgoing envelope when the insert is removed.  The mailer is constructed in a continuous manner from four vertically aligned webs of paper, with the interior webs having a width less than the top and bottom webs by an amount corresponding to the width of strips of adhesive along the sides of the business forms holding the top and bottom plies together.  All the webs except the insert sheet web are thumb notched, and the carbonizing bond and insert web are simultaneously die cut.          .

Title: Vacuum insulated sorbent-driven refrigeration device
Inventor: SABIN CULLEN M
IPC: F25D9/00
Filed: 1991-04-08
Abstract: VACUUM INSULATED SORBENT-DRIVEN                   REFRIGERATION DEVICE                  Abstract of the Disclosure Disclosed is a self-contained, rapid cooling device that retains heat produced from the cooling process and can be stored for indefinite periods without losing its cooling potential.  A liquid in a first chamber undergoes a change of phase into vapor which cools the first chamber.  A second chamber forms a vacuum insulation about a third chamber which contains a sorbent.  The sorbent in the third chamber is in fluid communication with the vapor and removes the vapor from the first chamber.  The device is self-contained because a material in contact with the sorbent removes the heat from the sorbent to prevent the reduction in the cooling effect produced by the first chamber.  In addition, a vacuum insulation about the third chamber keeps the heated sorbent from diminishing that cooling effect.     [JRR-2086] JRN-6347:/pd LIQUI.02A

Title: Method for electrochemical measuring the corrosion rate of reinforcement in concrete structures, sensors and device for application of the method
Inventor: FELIU SEBASTIAN
IPC: G01N17/02
Filed: 1991-05-17
Abstract: SUMMARY OF THE INVENTION            METHOD FOR ELECTROCHEMICAL MEASURING THE CORROSION RATE OF REINFORCEMENT IN CONCRETE STRUCTURES, SENSORS AND           DEVICE FOR APPLICATION OF THE METHOD.     The method obtains the corrosion rate by using a direct current and taking into account the reinforcement   area really affected by an electrical signal.  The signal is applied to the reinforcement through a ring shaped counterelectrode (4), controlled by a main reference electrode (5) housed therein, the following co-operating with the measurements:  a) a series of reference electrodes (7, 8, 9); or b) two concentric counterelectro-des (10, 11), or c) two reference electrodes (13, 14), and one concentric ring shaped counterelectrode (12).  A True Polarization Resistance value is obtained from the apparent resistance one corrected with the value of the critical -length or the signal attenuation coefficient, or through extrapolation of the values obtained with growing  size electrodes, or by confining the electrical signal within a given space.  The described methodology practical realization is pos-sible by means of a corrosion rate meter (6) developed for the envisaged invention.  Figures 1 and 2.

IPC: H04N7/16
Filed: 1991-06-05
Abstract: Specific text and/or graphic messages for individual subscribers or groups of subscribers are distributed on a communications network such as a cable television system.  An addressable controller communicates with a plurality of subscriber terminals served by the network.  Each subscriber terminal is assigned to a primary message group and may be assigned to one or more message subgroups. Messages are input to the addressable controller for subsequent transmission to a subscriber terminal for display.  The messages are tagged with distribution data defining at least one primary message group or message subgroup to receive the message.  The tagged text messages are transmitted over the network together with signals from network service providers.  Global messages can be sent by leaving the distribution data field blank, or filling it with a special code such as a string of zeros.  Wild card tags are also permitted.  A subscriber terminal for receiving the messages has a first path for processing a service signal received from the network and a second path for processing a message signal received from the network.  The distribution data is retrieved from a received message and used to determine if the message is targeted to the subscriber terminal.  If so, the message is processed for display.  The message can be displayed alone or overlaid on a video program signal being viewed.

Title: Device for dolls, activator of head movement, voice sound and light
Inventor: FERRI JAIME
IPC: A63H3/33
Filed: 1991-08-14
Abstract: A B S T R A C T DEVICE FOR DOLLS, ACTIVATOR OF HEAD MOVEMENT, VOICE SOUND AND LIGHT.     This device is based on a piece which is moved when the doll's arm is lifted, causing her head to rotate towards that arm and closing the circuit which produces  laughing sounds  and sentences. On the other hand, when the doll's arm is down the circuit activation produces crying sounds. When the arm is down, the above mentioned circuit is activated by pushing the doll's head sideways, either by pulling her hair combing it or by any other circumnstance This tilt places a vertical elastic appendix on a ring - both elements are fit-ted in the head's assembly core, thus closing the above mentioned circuit.

Abstract: Le dispositif comporte un outil d'intervention constitué par exemple d'un ensemble de pompage et d'un ensemble de mesure qui sont associés à une colonne de production et descendus dans un puits.      La liaison entre l'un au moins des deux ensembles et une installation de surface est effectuée au moyen d'un câble multi-conducteurs pourvu d'un connecteur enfichable de façon différée et transporté jusqu'audit ensemble par un courant de fluide. Pour éviter les effets indésirables que peut avoir le fluide de pompage sur les instruments de mesure ou d'éventuelles impossibilités de circulation avec certains moyens de pompage, on installe sur la colonne à proximité de l'ensemble concerné ou de chacun d'eux, une vanne de dérivation permettant l'échappement du fluide à l'extérieur de la colonne. Cette vanne est par exemple une vanne coulissante, le connecteur étant pourvu de moyens pour ouvrir et fermer cette vanne dans ses translations au voisinage de sa position d'enfichage.      Application à la production d'effluents pétroliers par exemple.
