Abstract: ABSTRACT OF THE DISCLOSURE         A toaster/oven comprises a housing and a cooking chamber defined within the housing by a cooking chamber bottom panel, first and second cooking chamber side panels, a cooking chamber top panel and a cooking chamber back panel (which may be removable), the cooking chamber thereby defining a front opening.  A door is pivotally mounted to the housing for closing the front opening.  Removable cooking chamber side liners are removably mounted to the cooking chamber side panels and define grooves for supporting at least one rack therebetween.  Each cooking chamber side liner has an offset flange including an offset portion and a tip extending from the top edge thereof and bottom tabs extending perpendicularly from the bottom edge thereof.  Each cooking chamber side panel defines slot openings cooperatively positioned for receiving the offset flange and bottom tabs of one of the cooking chamber side liners for removably mounting the cooking chamber side liner thereto. Mounting is accomplished by sequentially inserting the offset top flange into the upper slot opening in the cooking chamber side panel and then pivoting the cooking chamber side liner about its top offset flange to insert the bottom tabs in their respective slot openings.  Removal of the cooking chamber side liners is achieved by reversing the aforesaid procedure.  The rack-receiving grooves are defined in a raised section of the cooking chamber side liners, each groove having a back portion and divergin legs, whereby the grooves are "open" for cleaning, and the raised section is characterized by an incline transition to the flat perimeter of the removable cooking chamber side liner whereby the raised sections resists accumulation of food soilage and is easy to clean.

Abstract: ABSTRACT                     CRATES     A crate for bottles with cylindrical body portions has double-skinned corner portions which define with portions of an internal partitioning grid corner compartments for bottles.  The inner skin of the corner portion is formed with vertical ribs adjacent the grid portions.  These ribs, which are interconnected with the outer skin of the corner portion to form hollow columns therewith, strengthen the corner portions and allow the spacing of the skins thereof to be reduced so that the size of the compartment can be increased for given external crate dimensions, and as the ribs are located adjacent the partitioning portions they occupy space which would otherwise be free and do not reduce the effective size of the corner compartments.

Abstract: ABSTRACT            In megahertz ultrasonic echoscopy of objects, echoscopes having a time gain compensation facility are often used.          To ensure that a uniform ultrasonic echo signal is obtained at a predetermined depth within an object, the present invention varies the sensitivity of the time gain compensation for each pulse of ultrasonic energy used to obtain an echogram of the object.  The present invention may include means to vary the slope of the the time gain compensation so that at other predetermined depths  within the object, echo signals of respective intensities are received, thus overcoming problems due to shadowing by ultrasonically highly absorbing regions of the object.        The main application of the invention is in medical diagnosis.

Abstract: ABSTRACT OF THE DISCLOSURE              The specification describes a tone generator for producing an audible sound for a predetermined time period in response to the occurrence of one or more predetermined condi-tions. The tone generator comprises  a diaphragm mounted within a resonant sound cavity that is activated by an electromagnetic assembly which is in turn driven by the output signal from an oscillator circuit.   The circuit utilizes a triple positive temperature coefficient (PTC) resistor, with one resistor used as a primary heating element, another as a switching element for a lamp, and the third as a logic switching element for the logic signal that times the tone generator.  The control logic and timing circuit is adapted to produce the proper timed logic signal despite the absence of  a  lamp in the circuit, or a lamp failure.

Abstract: PRINTWHEEL HOMING APPARATUS              Abstract of the Disclosure In a printwheel type of printer using a selection stepper motor for driving the printwheel, means are provided for performing printwheel homing operation upon occurrence of predetermined events.  Such an event, is detected and reported to microprocessor means which drive motion means for bringing the printer carriage assembly to a first extreme left position where a stop element fixed relative to the printwheel rotation is made to enter the path of another stop element attached to rotate with the printwheel. Subsequently, the selection stepper motor driving the printwheel is driven for a number of steps at least equal to one motor revolution to ensure reaching inhibition of the printwheel rotation by bringing the rotating stop element into contact with the relatively fixed stop element. The carriage is then moved back to the left margin writing position where the relatively fixed stop element is withdrawn from the path of the other stop element and the angular printwheel home position is noted and stored by the microprocessor means.

Abstract: A B S T R A C T   This novel laser comprises Q terraced semiconductor substrate having a relatively thick part and a relatively thin part with a step part therebetween.  Semiconductor layers are formed over the substrate and include an upper clad layer and a lower clad layer with an active layer therebetween, the active layer having an inclined region extending downwardly from a position above the step part to R position above the relatively thin part of the substrate.  An overriding layer is formed on the upper clad layer and has opposite conductivity type to that of the upper clad layer.  A further layer having the same conductivity type as that of the overriding layer is formed on the overriding layer, such further layer having a stripe-shaped through-opening which is located above and slightly to one side of the inclined region of the active layer in a direction away from the step, such through-opening exposing a surface region of the overriding layer at the bottom of the through-opening.  A conduction layer is formed at least on the sides and bottom of the through-opening and extends towards and contacts the further layer.  A first electrode layer is formed in contact with the conduction layer in the through-opening and a second electrode is formed on the bottom face of the substrate.  Short-circuiting of the p-n junction caused by solder creep from the bond between the device and its heat sink is avoided by the above structure, which provides flat surfaces at the interface between the device and the heat sink.
