Abstract: ABSTRACT                     Applicator An applicator for applying liquids to surfaces, especially highly mobile liquids of low viscosity, the applicator comprising a cap-like body (30) in a transverse wall (50) of which is a dispensing aperture (60).   An applicator pad (90) is bonded to the outside of the transverse wall and there is a diaphragm (70) on the other side of the transverse wall, covering the dispensing aperture.  The diaphragm (70) has a slit (80),  radially spaced from the dispensing aperture.     An  actuator member  (100) extending through the dispensing aperture (60) rests with one end in contact with the diaphragm (70) and its other end in the applicator pad (90) so that pressure on the applicator pad (90) is transmitted via the actuator member (100) to displace the diaphragm (70) from the dispensing aperture (60) and open the slit (80).     The applicator resists accidental discharge of liquid and is particularly useful for applying treatment liquids to the leather of shoe uppers to impart a shine.

Abstract: ABSTRACT OF THE DISCLOSURE          A liquid level sensor includes a pair of sonic waveguides separated from and parallel to one another. The waveguide pair together define axially separated pairs of lens surfaces so that sonic pulses are coupled therebetween in a time phase relationship when liquid covers those lens pairs below the liquid level, cross coupling of those lens pairs above the liquid level thereby being prevented.  Since the axial separation dimension of the lens pairs is known as well as the vessel geometry and location of the waveguide pair in the vessel, counting the pulses returned by virtue of such cross coupling of those lens pairs below the liquid level will establish accurate level detection by standard algorithmic techniques.

Abstract: ABSTRACT OF THE DISCLOSURE         An endless impervious, oil, abrasion and crush resisting belt for paper making machinery such as presses, especially of the extended nip type, calender rolls, and the like has a woven fiber base, such as scrim, and a urethane coating impregnating the base providing an integral layer of substantial thickness with pores forming a granite like finish providing excellent paper release properties.  The surface finish of the belt can be modified with subsequent grinding and coating treatments and can be grooved if desired.  The belt is formed by looping an endless scrim blanket around driving rollers providing a travelling run which is sprayed with a two component polyurethane coating which quickly gels to accommodate building up of a layer of the desired thickness by controlling the fluid flow and the speed of the travelling run.

Abstract: ABSTRACT       A gerotor pump is arranged for unidirectional flow irrespective of direction of rotation of the pump by arranging for displacement of the axis of eccentricity of the annulus and rotor upon drive reversal, the annulus being mounted in a carrier 14, Figure 1, with freedom for movement in a first direction within the carrier, whilst the carrier itself is pivoted (24) in an outer . housing 15, the carrier being free for movement in a second direction within the housing.  The effect of normal drive of the rotor is to hold the parts in the Figure 1 position whilst pumping continues, but in the event of drive reversal a pressure fluctuation causes the annulus to be displaced within the carrier and then the carrier to be displaced within the housing so as to bring the parts to substantially the mirror image of the Figure 1 position allowing continued pumping in the same direction from inlet to outlet under reversed drive.

Abstract: ABSTRACT        A testing or  treating  tool  enables either squeeze packer elements or inflatable packer elements to isolate an interval  of  the  well  bore.   A  pump  provides  hydraulic pressure to nove the packer elements into sealing engagement with the well bore wall by manipulation of a tubular member which supports the tool in the well bore.  The tool includes a  sensor  which  is  responsive  to  a pressure   differential between the hydrostatic pressure in the well bore and the pressure in the isolated zone,  or interval,  in the well to increase the hydraulic pressure acting on the elements when the pressure in the well bore exceeds the pressure in the isolated zone to inhibit creep of the packers along the well bore wall.  A collection reservoir receives fluid displaced from the well bore as the packers sealably engage the well bore.

Abstract: COMPUTERIZED TRANSACTION CARD  WITH INDUCTIVE DATA TRANSFER            Abstract:        A transaction card having in it a semiconductor microcomputer with data storing capability is inserted into a receptor having circuitry for interacting with the microcomputer.  Operating power and a clock signal for the microcomputer are transferred from the receptor to the card via an inductive coupling between a coil and magnetic core in the receptor and a coil and ferromagnetic member constituting a flexible wafer inductive device ("FWID") in the card.  For purposes of data transfer between the card and receptor, the card includes two additional FWIDS which, when the card is in the receptor, are inductively coupled with corresponding coils in the receptor.  One of such additional FWIDS is used to transfer data from the microcomputer in the card to a microcomputer in the receptor, while the other additional FWID is used for data transfer in the opposite direction between these two microcomputers.  That data transfer is accomplished by modulating the data signal on the clock, inductively transmitting the modulated signal across the discontinuity between the card and the receptor, and then demodulating the modulated signal to recover a replica of the original data signal.

Abstract: Abstract of the Disclosure A side rail assembly for a bed-like stretcher includes a tubular side rail with first and second tubular posts connected at each end.  Each of a pair of mounting members connected near each end of the stretcher frame includes first and second vertically spaced-apart pivotal connection points.  First and second linkage bars are pivotally connected between each of the posts and the connection points of one mounting member to form a pivotally connected quadrilateral.  A handle is mounted to each of the posts for pivotal movement about a horizontal line, while a handle linkage connects the handles so that movement of either handle causes identical movement by the other.  A latch on each post cooperates with a catch fixedly attached to the frame.  A latch actuator connects each latch with a handle, so that pivotal movement of either handle causes the latches to disengage from the catches, permitting lowering of the side rail assembly.
