Title: Household refrigerator assembly
Inventor: JENKINS THOMAS E
IPC: F25D23/06
Filed: 1991-01-17
Abstract: HOUSEHOLD REFRIGERATOR ASSEMBLY                         ABSTRACT A refrigerator cabinet having an outer metal shell and an inner liner spaced from the shell with foamed-in-place thermal insulation therebetween.  The cabinet has an outer metal shell open at the front with two side walls and a top wall each folded to provide a front face with an open fold behind the front face. There is a machinery compartment wall near the bottom of the refrigerator cabinet which is bent upwardly and terminates in a curved front lip having a downwardly facing opening.  The inner liner has a peripheral flange which is received in the open fold behind the front face along the side and top walls.  At the bottom of the cabinet is a bottom rail assembly which includes a metal cross member with each end secured to the front face at each of the side walls.  The metal cross member has a strengthing groove extending between the ends and also has two spaced tabs formed to project downwardly into the groove.  There is a snap-on trim member extending the length of the cross member and secured along the top edge and has a front vertical wall engaging the front surface of the cross member terminating at the bottom in a reverse bend hook with the end of the hook engaging the tabs of the cross member.  The front vertical wall has an open reverse bend at the top to form a rear wall engaging the rear surface of the cross member.  The rear wall has an open reverse bend away from the cross member to receive the bottom peripheral flange of the inner liner and forming an upwardly extending leg having a terminal end received in the downwardly facing opening of the lip of the compartment wall.  With this structural arrangement the bottom rail assembly prevents egress of foam past the bottom peripheral flange of the inner liner and past the lip of the machinery compartment wall during the foamed-in-place thermal insulation operation.

Title: Soft plastic film packaging for parallelepiped-shaped piles of flexible flat objects
Inventor: HADZELEK FRANZ
IPC: B65D65/28
Filed: 1991-02-28
Abstract: Abstract A soft plastic film packaging for piles of paper serviettes, for example, has in one of its covering walls a sealing section, which can be torn open or off, for an aperture for the removal of said objects, which is disposed in a corner region of a covering wall. The paper serviettes remaining in the package after opening can not fall out and the risk of their becoming dirty is only slight. When taking out the topmost  paper  serviette,  this  is  automatically  folded together so that it fits through the removal aperture, but it subsequently assumes its flat shape again without any creases remaining.

Inventor: OHTA KENJI
IPC: G11B5/187
Filed: 1991-06-06
Abstract: A magneto-optical recording/reproducing device which records  information  by  irradiating  a  light  beam  of constant intensity on a magneto-optical recording medium while  simultaneously applying a magnetic  field  thereon through a recording magnetic head; and which reproduces the recorded information through a reproducing magnetic head.  The magneto-optical recording medium has a magnetic film formed on a translucent substrate and the magnetic field applied through the recording magnetic head reverses in  response  to  the  information  to  be  recorded.   The recording magnetic head and the reproducing magnetic head are integrally provided on a single magnetic core in order to set their positions easily with respect to each other.          By making a magnetic  core end-face of the  reproducing magnetic head smaller than a light beam spot, information recorded on areas smaller than the light beam spot can be reproduced.  A large reproduced output may be achieved by using a magneto-optical recording medium which has a soft magnetic material  layer made of soft magnetic material provided between the substrate and the magnetic film.

Abstract: ABSTRACT          The present invention relates to a method of connecting a ceramic material to another material. According to the present method as ceramic material porous material is used that prior to making a connection it is gradually compacted from the contact surface with the greatest density at the contact surface, wherein on the contact surface of the porous material a mixture of titanium hydride (TiH2) and quartz flour (SiO2) is applied. Then the so treated porous ceramic material is heated to 1200-1800°C during 1-40 hours.          Finally the so compacted porous ceramic material in a manner known per se is connected to the other material. Preferably the treated porous ceramic material is heated to 1300-1500°C during 10-20 hours. Advantageously the weight proportion of TiH2 and SiO2 in the mixture is 95:5 to 5:95 and preferably 35:65 to 65:35.

IPC: G10L21/0208
Filed: 1991-02-25
Abstract: A method is disclosed for use in preprocessing noisy speech to minimize likelihood of error in estimation for use in a recognizer.  The computationally-feasible technique, herein called Minimum-Mean-Log-Spectral-Distance (MMLSD) estimation using mixture models and Markov models, comprises the steps of calculating for each vector of speech in the presence of noise corresponding to a single time frame, an estimate of clean speech, where the basic assumptions of the method of the estimator are that the probability distribution of clean speech can be modeled by a mixture of components each representing a different speech class assuming different frequency channels are uncorrelated within each class and that noise at different frequency channels is uncorrelated. In a further embodiment of the invention, the method comprises the steps of calculating for each sequence of vectors of speech in the presence of noise corresponding to a sequence of time frames, an estimate of clean speech, where the basic assumptions of the method of the estimator are that the probability distribution of clean speech can be modeled by a Markov process assuming different frequency channels are uncorrelated within each state of the Markov process and that noise at different frequency channels is uncorrelated.

Abstract: A skylight operator includes a chain drive driven by a motor.  Polarity of power applied to the motor is controlled to  selectively  open  or  close  the  window.    Polarity  is controlled by an H-bridge switching circuit driven by a microcontroller.  The microcontroller receives commands from any one of a plurality of control devices.   The operator includes a feedback circuit using a hall effect sensor in connection with a ring magnet on the motor shaft for sensing incremental movement of the motor, representing movement of the window.  A potentiometer control device allows unattended full or partial opening of the window.  A user need only turn the potentiometer knob to a desired amount of opening.  The microcontroller in response to such a command compares the command to the feedback signal and controls the motor to minimize the difference between the two.

Abstract: ABSTRACT OF DISCLOSURE        A method of and apparatus for drawing wire of high surface quality and cleanliness by avoiding slip between the wire and drawing block and thereby enabling clean coolants to he used.   The apparatus comprises a plurality of dies in series and a drawing block for drawing the wire through each die.  Each drawing block is driven by independently adjustable means which derive their motive power from a common source which is itself adjustable and which also provides power to a take-off reel also independently adjustable.  Each of the drawing blocks  has  a  plain  cylindrical  surface  in  driving engagement with the wire.       In threading of the wire, the torque exerted by each drawing block is adjusted in sequence starting with the block associated with the first die so that the force required to draw the wire through the die and around the drawing block and any associated idler or subsequent dies and drawing blocks is a minimum.  Once each of the drawing blocks and the take-off reel is set in this manner the machine can be run up to speed by adjusting power from the common source.
