Title: General-purpose cleaning composition
Inventor: CLARKE DAVID E
IPC: C11D10/02
Filed: 1987-04-16
Granted: 1991-08-27
Abstract: ABSTRACT          A liquid general-purpose cleaner, having improved non-streak and cleaning properties, is obtained if in a liquid-compatible medium which comprises a nonionic surfactant, an at least partially esterified resin and water or a mixture of water and a water-miscible organic solvent, as nonionic a topped nonionic surfactant is used containing less than 2% by weight of non-alkoxylated material and less than 4% by weight of mono-alkoxylated material. By using this nonionic surfactant, less partially esterified resin and less perfume are required to achieve effects similar to those obtained when a non-topped nonionic surfactant is used.

Abstract: ABSTRACT    A hasp-type latch includes a hasp member with a base having a base wall and a pair of upstanding side walls and a latch arm which is pivotally mounted thereon.  The side walls of the pad include releasable latching elements which are engageable with the arm in its open position to hold it in that position.  The staple member has a base with a top wall and a depending sidewall defining a cavity thereunder, and the top wall has an opening therethrough.  A post member has a pedestal portion which extends through the opening into the cavity of the staple base, and a post portion which extends upwardly through the aperture in the arm in its closed position.  The pedestal portion includes securing means in -the cavity which extends outwardly beyond the opening in the top wall to prevent the post member from being pulled through that opening.  Generally the post member is rotatable to locate an elongate axis so that it overlies a portion of the hinge leaf in the closed position and prevents  its being pivoted upwardly.  The post member may include an integrally formed lock such as combination locks and key locks to lock the post member in this latching position.

Title: Shear connector
Inventor: HATZINIKOLAS MICHAEL A
IPC: E04B1/76
Filed: 1988-01-13
Granted: 1992-01-21
Abstract: SHEAR CONNECTOR            ABSTRACT OF THE DISCLOSURE          A tie assembly is used in a cavity wall having a back-up wall and a brick veneer to secure the brick veneer to the back-up wall.  The tie assembly includes a plate that is secured to the back-up wall in a vertical orientation, with an tying portion of the plate project-ing towards the brick veneer.  A series of tie openings are spaced along the outer edge of the plate to receive a tie bar that projects into the mortar between adjacent brick courses.  The tie bar cooperates with the plate to transmit loads oriented in any direction in the plane of the plate between the brick veneer and the back-up wall.          This means that shear loadings as well as lateral loads are transmitted between the veneer and the back up wall, so that the two act as a truss structure.

Abstract: CIRCUIT AND METHOD FOR PERFORMING EQUAL DUTY CYCLE ODD VALUE CLOCK DIVISION AND CLOCK SYNCHRONIZATION                 Abstract of the Disclosure A circuit for dividing a master clock by an odd integral value and producing a 50% duty cycle. A state machine develops set and clear signals which are of a timing proportion of n: n + 1, where 2n + 1 is the divisor value. The set signal is provided to one input of a bistable multivibrator or S-R latch to set the multivibrator to a given state, while the clear signal is combined with the master clock signal to delay or disable the clearing of the multivibrator by 1/2 count of the master clock, so that an n + 1/2: n + 1/2 proportion output clock signal is developed. Additionally, the circuit includes a state machine which determines which of a series of differing frequency master clock signals is active and when an external triggering event occurs so that the following rising edge of the output clock signal is delayed until a determined time after the triggering event to allow synchronization of the output clock signal.

Abstract: A first hydrogen sulphide containing waste gas stream from an oil refinery is combusted in a first combustion chamber 16 using pure oxygen to support combustion.  The combustion products are cooled in heat exchanger 20, and a part of the combustion products are recycled to the chamber 16 to moderate the temperature therein.  The remainder of the combustion products are mixed with a second hydrogen sulphide containing waste gas stream of different composition from the first stream.  A proportion of the hydrogen sulphide content of the mixed stream is combusted in combustion chamber 28 again using pure oxygen to support the combustion.  The resulting sulphur dioxide reacts with residual hydrogen sulphide to form sulphur vapour.

Title: Multifocal ophthalmic lens
Inventor: PORTNEY VALDEMAR
IPC: G02B1/00
Filed: 1988-05-25
Granted: 1994-01-25
Abstract: ABSTRACT OF THE DISCLOSURE          An improved ophthalmic lens is disclosed which has a plurality of alternating power zones with a continuously varying power within each zone, as well as in transition from one zone to another.  In other words, a plurality of concentric zones (at least two) are provided in which the variation from far to near vision correction is continuous, i.e., from near correction focal power to far correction focal power, then back to near, and again back to far, or vice versa.  This change is continuous (progressive), without any abrupt correction changes, or "edges".        Two versions of the lens are disclosed.  In the first version continuous, alternating power variation is accomplished by a continuously changing curvature of the lens posterior surface, thereby altering the angle of impact of light rays on the eye.      In the second version continuous, alternating power variation is accomplished by creating non-homogeneous surface characteristics having refractive material indexes which continuously vary in the lens radial direction (out from the optical axis).
