Abstract: ?5-8021/-MK     TITLE           DIGITAL SPEED CONTROL SYSTEM     FOR SEWING MACHINES          ABSTRACT OF THE DISCLOSURE     A digital speed control system for a sewing machine comprises a digital speed setting device which responds to manual depression of a foot pedal by generating a digital position signal.  A variable frequency divider divides the frequency of speed related pulses so that its output frequency is an integral submultiple of the input frequency, which is variable as a function of the digital position signal.          A period detector senses the interval between pulses that occur successively at the output of the frequency divider and generates a binary data representing the sensed interval.        The interval representing data is translated into a second period data in an arithmetic unit according to a predetermined transfer function.  A pulse generator translates the second period data into a pulse for activating a magnetic clutch or a magnetic brake depending on a sign of the second period data to accelerate or decelerate the sewing machine.

Abstract: Abstract:    The present invention relates to an improvement in magnetic recording tape cassettes.  A magnetic recording tape cassette is provided comprising a bottom case and a top case assembled with the bottom case to provide a tape chamber.  One or more tape roll members are mounted in the tape chamber.  Each tape role member includes a hub with a top projection for pivoting the hub.  Each tape role member is mounted on a bottom wall of the bottom case and a magnetic recording tape is wound on the hub.  A resilient spring member is fixed to the under surface of a top wall of the top case and has one or more arms, the free ends of which extend to the top projection of the corresponding hubs to resiliently, rotatably support the hubs.  The improvement comprises a recess defined in the under surface of the top wall of the top case for accommodating a fixed part of the spring member.  The recess has a depth substantially equal to or larger than the thickness of the spring member.  The recess extends to at least a position corresponding to the maximum diameter of the tape roll member from a position where the spring member is fixed.

Abstract: Keefer 19/w REVERSE OSMOSIS APPARATUS AND METHOD        USING INTEGRAL VALVE     ABSTRACT                  Reverse osmosis pumping apparatus for pumping under pressure feed fluid to selective membrane means which permeate and reject respectively permeate and concentrate fluid fractions. Apparatus has a feed cylinder divided into pumping and expansion chambers by a feed displacer mounted on displacer rod for relative reciprocation. Main valve controls concentrate fluid flow relative to expansion chamber and is mounted for movement relative to and along displacer rod axis and is responsive to force applying reciprocation action to pump such that reversal of force reverses main valve. Recirculating pump can be driven from displacer rod to pump concentrate fluid over membranes to maintain permeate fraction discharge during induction stroke of feed cylinder. Recirculating pump has valve also actuated by reversal of pumping action to direct concentrate flow to membranes, or to the expansion chamber for depressurization to assist in pressurizing feed fluid. Because main valve mechanism is actuated by change in reciprocation action, it is not necessary to complete a full displacer stroke before stroke direction reversal. Thus apparatus is particularly suited for power sources which have a non-constant amplitude and frequency, such as manual, wave or wind power sources.

Abstract: ABSTRACT:     A process is disclosed by means of which an increase in particle size of a micro-ground anti-inflammatory steroid in aerosol propellant is prevented.  The increase in particle size is prevented at the suspending stage when the solubility of the steroid in the propellant is reduced by using low temperature and by initially mixing only a small portion of the propellant with the steroid.  If desired, the smallest dissolved steroid particles can be removed by filtering.  The particle size does not increase even afterwards, as long as the suspension is stabilized for a sufficiently long time before the temperature is raised or the rest of the propellant is added.

As a consequence, the beam spot can be maintained substantially in the form of a true circle not only at the center of the screen but also at the portions adjacent to the peripheries thereof.  Thus, the resolution at the portions adjacent to the peripheries of the screen can be improved and consequently high-quality images can be represented over the whole surface of the screen.

Abstract: CONTACT LENS CONSTRUCTION             ABSTRACT OF THE DISCLOSURE          Various forms of multifocal contact lenses can be produced having improved properties.  The surface of a lens (1) to be polished is brought into contact with a polishing compound (19) associated with a flexible (but non-resilient) sheet (18), causing the sheet (18) to flex.  Fluid pressure is applied to the sheet counteracting the flexing as a result of lens contact, so that polishing compound associated with the sheet makes contact with the lens surface with uniform force distribution. Relative rotation between the lens (1) and sheet (18) is effected so that all portions of the lens surface in contact with the polishing compound are polished to the same extent.  The lens is then ground to provide a multifocal lens.  A hydrophilic or silicone multifocal contact lens having desired distance and intermediate powers may be constructed by acting on the lens (2) so that it is capable of accepting grinding activity, and the grinding it without distorting it. The lens (2) may be backed by a chuck (34) or hard lens (3), or frozen, and ground by grinding apparatus (60) while backed or frozen.

The cartridge is characterized by one corner of the cartridge through which the tape passes being provided with a leader block receiving well in which the bottom of the well surface defines the open-ing in the cartridge through which the tape moves. Other opposed surfaces of the leader block well are arranged to engage the leading and trailing surfaces of the leader block in a clamping relationship such that the opening in the cartridge is substantially sealed by the leader block to prevent contamination from entering the cartridge when the cartridge is not in use.
