Abstract: ABSTRACT OF THE DISCLOSURE     A wet motor gerotor pump has an armature including first and second shaft ends.  The outlet housing has a bore with a bushing mounted therein for positioning the second shaft end and for rotatably supporting the second shaft end  the bushing has an exterior periphery with a raised portion extending circumferentially thereabout and radially away from the second shaft end portion, the raised portion being in contact with the bore to permit the pivoting of the armature shaft axis thereat in response to an axial alignment of the first shaft end portion; and anti-rotation means coupling the bushing and the outlet housing to prevent circumferential rota-tion of the bushing relative to the housing while permitting the second shaft end to rotate within the bushing.

Abstract: Abstract PRODUCTION PROCESS OF PRE-FOAMED PARTICLES        Pre-foamed particles are produced by dispersing resin particles, which contain nucleocells, in a dispersing medium in a closed vessel, heating the contents to a temperature of the softening point of the particles or higher and holding the contents at the temperature for a predetermined period of time while pressurizing the contents with an inorganic gas, and then opening the vessel at one end thereof so as to release the particles and medium into an atmosphere of a pressure lower than the internal pressure of the vessel, thereby causing the resin particles to foam.          The above production process provides good pre-foamed particles with ease and without failure.   It is also possible to avoid deleterious effects due to the swelling action of foaming agents.

Abstract: ABSTRACT           A device for cutting successive sheets from a traveling web includes a pair of thin-walled knife-carrying cutting cylinders concentrically mounted over fixed supporting shafts.  To prevent ringing of the shafts at high cutting frequencies, due to resonant frequency interference, the support shaft is formed by a body having an imperforate cylindrical wall.  The cylindrical wall of the support shaft is closed at both ends to form an uninterrupted cylindrical cavity extending from end to end of the cylindrical wall. Furthermore, and to prevent poor cuts due to changes in the alignment of the cutting knives, the amplitude of vibrations occurring at the time of each cut is reduced.  The cavity of the support shaft is filled with a flowable vibration damping material which is not firmly affixed to the cavity walls and thus forms no significant part of the mass of the support shaft.

Abstract: ABSTRACT OF THE DISCLOSURE A space conditioning closed loop refrigeration system, particularly a vehicle air conditioning system utilizing a positive displacement compressor having a slide valve for varying the capacity and shiftable between full load and full unload positions and vice versa and driven therebetween by a linear fluid motor having a movable member coupled to the slide valve and forming a first chamber which is normally dumped via a slide valve modulator to compressor suction pressure and a second chamber open to compressor discharge pressure.   A restricted passage between chambers tends to cause the first chamber to reach compressor discharge pressure absent that chamber dumping to suction.  The slide valve modulator selectively activates the venting of the first chamber to compressor suction pressure in response to fall of suction pressure below a predetermined value to prevent a serious reduction in evaporator temperature caused by either a reduction in load on the evaporator, an increase in speed of the compressor, or both.   A temperature unloader in the form of a normally closed valve is connected within a bypass passage bypassing the slide valve modulator to insure dumping of the first chamber to suction in response to a predetermined drop in temperature of the space to be conditioned, irrespective of the level of compressor suction pressure.

Abstract: Abstract:   An ophthalmic device and system for measuring and controlling relative pressure of fluid inside an ocular globe includes a surgical instrument which is adapted to penetrate the ocular globe.  A fluid pressure transducer is mounted on the instrument so that, when the instrument penetrates the ocular globe, the transducer is located adjacent to an opening that communicates with the interior of the globe so that it can react to pressure changes in the fluid therein and generate signals in response to pressure changes in the fluid.  The signal is transmitted external of the instrument to a pump or other fluid transfer device which is operatively connected to the transducer for first receiving signals and then supplying or removing fluid from the ocular globe in response to the signals according to a predetermined set of instructions.          The pump is connected to a closed loop in which fluid is continuously circulated.  Fluctuations in intraocular pressure cause the pump to speed up or slow down and then supply fluid to or remove fluid from the ocular globe through a conduit connected to the closed loop.

Abstract: ABSTRACT OF THE DISCLOSURE     The device consists of a base sheet of impermeable plastic such as vinyl, or the like, and a guaiac stool receptor sheet adhesively secured thereto.  The base sheet is sufficiently larger than the receptor sheet so as to form an impermeable skirt which surrounds the receptor sheet so as to form an hermetic barrier protecting the receptor sheet on the underneath one of two of the devices when stacked one on top of the other.  A performance/control monitor is included on the device.  The monitor includes a peroxidase positive material such as hematin, or the like, which confirms the reactivity of the guaiac-impreg-nated sheet, as well as the activity of the peroxide developing solution.  The monitor material is kept out of reactive contact with the guaiac receptor sheet until the developer reagent is applied to the device.  A stack of the devices is packed in a sealed container of plastic, or the like, so that the individual devices can be removed from the container one at a time.          The devices are designed for use in the physician's office for reception of stool smears taken manually on a rubber glove or finger cot by the physician from patients.
