Abstract: LOSS HEAT SUPPRESSION APPARATUS     AND METHOD FOR HEAT PUMP               Abstract of the Disclosure A compressor unit for use with a heat pump system wherein a motor-driven compressor is disposed within a casing which can be placed indoors or outdoors. Vapor from the suction side of the system is directed into and through the compressor, through an oil separator-muffler, and then into contact with liquid from the high side of the system, the liquid being directed onto a rotating disk to form a spray which contacts and thereby de-superheats the compressor discharge vapor.  The de-superheated vapor then moves into and through the air gaps of the compressor motor in heat exchange relationship thereto where it is re-superheated.  The re-superheated vapor then leaves the fan ports of the motor and enters the open top of a vertical standpipe which also receives the excess liquid collected in a trough surrounding the upper end bell of the motor. The liquid is entrained in the re-superheated vapor and moves therewith out of the casing toward the four-way valve and the condenser coil of the system.

Abstract: Abstract of the Disclosure Method and apparatus for processing solid and viscous plastic materialor polymeric material and the like in which plastic or polymeric material is fed through an inlet into an enclosed passage of which opposed side walls are moving simultaneously toward an outlet and the material is processed and dragged forward by the moving side walls against a channel block and with progressive build up of pressure along said passage for discharging the processed material through the outlet form the enclosed passage.  Rotary apparatus for practicing the method includes one or more annular channels having opposed side walls and carried by a driven rotor member for movement relative to a housing of which an annular surface coaxial with the rotor cooper-ates with the walls of the channel or channels to form an enclosed annular passage or enclosed annular passages.  An inlet for feeding the plastic or polymeric material into each annular passage extends through the housing and an outlet for discharge of material from each passage is disposed circumfer-entially a major portion of a complete revolution from the inlet.  A channel block supported by the housing projects into each channel to hold the plastic or polymeric material for relative movement with respect to the channel side walls and to wipe or scrape the side walls moving past it, and is located between the outlet and the inlet to each annular passage.

Abstract: MICROFILM RECORDING AND DEVELOPING APPARATUS          ABSTRACT OF THE DISCLOSURE         The present invention describes a microfilm recording and developing apparatus, providing an improved method and device for advancing and processing exposed film.  The microfilm recording apparatus comprises a film storage means, a camera means, film advancing means, optical means, processing means, drive means and heating means.  The film advancing means transports a predetermined length of film from the film storage means to the camera means for exposure.  The optical means associated with the camera means optically imprints and photographically records an image on the exposed segment of film.  The processing means, responsive to actuation of the optical means, mechanically transports and chemically treats the exposed film.  The processing means includes a plurality of containers for developing, fixing, neutralizing and washing the exposed film.  The processing means further includes container film guide means and coupled sets of film engaging pinch rollers adjacent an entrance and exit of each one of the containers.          The pinch rollers are arranged so as to effect the conveyance of the exposed film in loop and self-threading fashion via the container film guide means through and from each one of the containers.  The drive means is coupled to the pinch rollers for film processing movement of the exposed film to a collection point.  The heating means dries the chemically treated film.

Abstract: Docket No. 11734 STAINING APPARATUS AND METHOD OF USING SAME ABSTRACT Apparatus and method are disclosed for applying liquid to a series of individual, substantially flat objects. The apparatus and method are particularly adapted for staining microscope slides. The apparatus comprises a fixed plate member and preferably an opposing plate member positioned substantially parallel to and movable toward and away from the fixed plate member, aligned by means of at least one guide member which engages said plate members. A series of movable spacing shims extend along the guide member for separating flat objects, such as glass slides. The flat objects are inserted into the apparatus while the movable plate member is positioned away from the fixed plate member. Once the flat objects have been inserted in the apparatus between adjacent spacing shims the movable plate member is moved toward the fixed plate member to clamp the flat objects in predetermined spaced parallel face-to-face relation. At least one opening located in the fixed plate member allows liquid to flow over adjacent edge portions of the flat objects and fill the capillary gaps formed between adjacent flat objects by the spacing shims. -1-
