Abstract: BREWING APPARATUS FOR  COFFEE AND THE LIKE          Abstract of the disclosure:  The present invention relates to an infusion apparatus, particularly such an apparatus for brewing coffee or the like where a receptacle such as a coffee basket is mounted on a water heating apparatus and a carafe is positioned underneath the infusion chamber.  The infusion chamber is made with relatively movable walls so that the cross-sectional area transverse to the direction of flow of liquid may be varied to vary the depth of infusion bed for a given quantity of coffee or the like in the chamber.          Two movable walls are disclosed together with an actuating mechanism with the movable walls and the actuating mechanism being of simple construction and readily assembled so that the use of screws, rivets, and so forth is not required.          The relatively movable walls are actuated by a rotatable plate connected to the walls which are positioned internally of the infusion chamber with rotation of the plate moving the walls toward and away from each other.  A clip is provided for holding the top of the filter against the top of the side walls of the receptacle forming the infusion chamber.

Abstract: ABSTRACT OF THE DISCLOSURE            A gasoline dispensing nozzle having a system for receiving vapors displaced from a motor vehicle gasoline tank being filled, and an interlock system for both preventing the dispensing of gasoline and closing the vapor receiving system until the discharge spout is properly inserted into the motor vehicle fillpipe.  The interlock system includes a first valve mounted in the vapor receiving system outside the discharge spout.  This first valve is opened when the nozzle is properly inserted into the fillpipe, and is interconnected with the automatic shut-off system of the nozzle so that dispensing of gasoline is permitted only when the nozzle is properly inserted into the fillpipe.  The interlock system also includes a second valve which closes the vapor receiving system, thereby preventing vapors from escaping, until the nozzle is properly inserted in the fillpipe.

Abstract: ABSTRACT     The present invention is directed generally to a mounting structure for semiconductors, and more particularly to a mounting structure for mounting a heat generating triac type semiconductor onto a heat dissipating device.  One conventional technique for mounting such semiconductor devices has been to thread a screw or other fastening device through an apertured mounting tab of the device and into the associated heat sink.  However, as the screw is tightened, the body portion containing the semiconductor device may tend to turn, causing the protruding electrical leads to become twisted and possible short circuits to be pro-duced.  The mounting structure of the present invention comprises a housing of dielectric material.  The housing has a body cavity for receiving the body portion of the switching device and for preventing lateral movement thereof' relative to the housing.  The depth of the body cavity is slightly greater than the thickness  of the body portion of the switching device to receive the complete body portion therein.  The housing has a tab cavity for receiving the mounting tab of the switching device, and bias means formed integrally with the tab cavity for biasing the mounting tab  outwardly from the housing.  Upon securing the housing to the heat sink with the switching device therein, the mounting tab will be biased into intimate heat transmitting contact with the heat sink.

Abstract: DRAWER AND CASE WITH ANTI-REBOUND MEANS                 ABSTRACT OF THE DISCLOSURE         The specification discloses a drawer and case assembly in which a polymer spring is utilized as an anti-rebound means.  The polymer spring is secured to the side of the case along side the drawer and the drawer includes a projecting detent in the form of an emboss which engages the polymer spring as the drawer passes.  When the drawer is in its normally closed position, the detent is located behind the polymer spring so that the drawer tends to be held closed once it is pushed into its closed position. The polymer spring will deflect, however, when one pulls a drawer and thereby pulls the detent past the head of the polymer spring.

A drive member mounted on the frame for rotation about a fixed axis and for axial movement relative to the drum between a retracted position and an extended posi-tion to drivingly engage one end of the shaft member is operable for selectively preventing rotation of the drum and for selectively moving the latch arms to an unlatching position to permit opening of the trap door.

Title: Contiguous element field access bubble  lattice file

Abstract: CONTIGUOUS ELEMENT FIELD ACCESS BUBBLE LATTICE FILE           Abstract of the Disclosure A bubble domain storage system is described which has the best features of contiguous element bubble propagation systems and bubble lattice file systems.  An array of magnetic bubble domains, such as a lattice, is moved along contiguous propagation patterns in response to the reorientation of a magnetic field in the plane of the bubble domain film.  Adjacent rows of bubble domains in the array move in opposite directions to provide individual storage loops within the array.  Information accessing can be achieved by the use of input/output registers similar to those used in other contiguous disk bubble domain storage systems.  For example, the storage system can be a conventional major/minor loop organization using contiguous element propagation patterns for the storage registers and for the input/output registers.          Every bit position in the storage registers is populated by a bubble domain where the average distance between adjacent bubble domains is less than that in a system where bubbles are isolated from one another. For example, the storage registers can be arranged so that the separation between adjacent bubble domains in the storage registers is 2-3 bubble diameters.  The bubbles are coded in terms of the magnetic properties of individual bubble domains, or a double layer structure can be used in which an array of bubble domains is in one layer and information bubble domains are in the other layer, coded in accordance with presence/ absence.  Viewed another way, the invention is a bubble storage system using contiguous propagation elements which is fully populated by inter-acting bubble domains.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus are provided for continuously extruding biaxially oriented and formed molded products from a web of thermoplastic material and further, continuously separating the products from the web selvage for further extrusion.  The method involves the steps of continu-ously extruding a relatively narrow web of thermoplastic material and con-tinuously transporting the extruded web at a first downstream velocity away from the point of extrusion while controlling the temperature of the web to an optimum value for biaxial orientation;  receiving and biaxially stretching the transported web in a continuous manner to effect biaxial orien-tation therein and to dimension the web for subsequent forming by increas-ing its length and width and decreasing its thickness and continuously transporting the biaxially oriented web at a second downstream velocity aw away from the point of biaxial orientation;  substantially immediately and continuously transferring the biaxially oriented web into conformal engage-ment with an undulating rotating peripheral surface travelling at substan-tially the second downstream velocity to preclude loss of such orientation; and forming products from the oriented,web, wherein stress placed in the thermoplastic material by the biaxial orientation is substantially main-tained from the initiation of the orientation to the forming of the products therein.  The apparatus is specially adapted to carry out that method.  Such method and system provided is very facile and variable with regard to unique and unusual shapes.  A continuous method with a relatively high speed of production and high quality control with a low inertia apparatus is readily effectuated.
