Abstract: These chemical formulations and agents are to be used as water treatment agents in industrial water systems to control and improve such factors as bacteriological contamination, pollution and cleanliness. Chemical limes, hydrosulfites and dispersants are used together in a formulation, in relatively low concentrations, to primarily inhibit and destroy slime and microorganisms. No toxicants as such are needed. In addition, the chemical lime particles can be coated to give a delayed and safer reaction with water and to give reduced dusting.

Abstract: This album comprises a backboard. Attached to the backboard are a plurality of transverse, parallel strips each coated at its underside with adhesive. Said strips are each adhered to the top face of the backboard, each strip having a section or portion inclined away from the top face of the backboard. Adhered to each of said inclined portions of said strips, is a bent back section or portion of a transverse release ribbon. Said ribbons have extending tab portions which may be grasped by fingers of the user to pull the release ribbon off and away from the strip to uncover the adhesive coated inclined section or portion of the strip. A photographic snap shot may be adhered at its lower end to said uncovered portion of the strip. The snapshots can each be folded 180.degree. from a position exposing the picture of the photo to a position in which the picture is hidden at the underside of the photo.

Abstract: This box comprises a case, and a cover hinged to the case at the rear of the box with the lower end of the cover spaced above the upper end of the case to leave a space therebetween when the cover is swung down toward the case. A display stand is removably fitted into the case and has an outwardly extending flange of uniform height, at the front, sides and rear thereof, interposed between the front, side and rear walls of the case and cover when the box is closed, to retain the case and cover in spaced parallel relation. The flanges of the display stand are exposed to view when the cover is closed. A sign holder is removably mounted and frictionally held on the display stand and comes out of the box with the display stand when the latter is removed from the box, to display the ring or other piece of jewelry to be displayed, and also to display the sign holder. The case and cover are substantially symmetrically disposed on opposite sides of said flanges.

Abstract: This knob assembly comprises a knob housing slidable on a body contained therein, and fixed to a centrally located control shaft. The body has means controlled by springs, to frictionally engage a disc non-rotatably keyed to a panel for said control shaft. Normally the knob housing can be freely spun, but when it is pushed in, it is lockingly engaged with the body whereby rotation of the pushed in knob housing will rotate the shaft with friction drag imposed on rotation of the shaft to thereby prevent inadvertent rotation of the shaft after setting of the angular position of the shaft. A spring causes the knob housing to pull out to disengage the knob housing from the body, to allow the knob housing to substantially spin freely again. The springs which cause friction between the body and the keyed disc, are stronger than the spring which pulls the knob housing out or returns it to normal when the knob housing is released.

Abstract: This chair comprises a chair body having arm rests and being fixed to tracks mounted for longitudinal movement on stationary tracks supported on a floor. Seat links, a leg rest and linkage mechanism connecting said seat links and leg rest to the body and to each other, permit the seat links, and leg rest to be moved from upright position to T.V. position, and then to fully reclined position, and back to T.V. position and upright position. Links are pivoted, connecting the stationary tracks and the movable tracks with said linkage mechanism, to move the body and its movable tracks, longitudinally forwardly relative to the stationary tracks as the seat links, backrest and leg rest move from upright to T.V. position, and to then move the body and its movable track, further forwardly longitudinally relative to the stationary track, as the seat links, backrest and leg rest move from T.V. position to fully reclined position.

Abstract: This is a hair brush for use with blow styling dryers. It comprises a handle from which there extends, in alignment with the handle, a tubular brush block formed with many air slots between radial tufts of brush bristles, so that air blown from a hot air styling dryer can be directed against the brush as the hair is brushed or as locks of hair are wound around the brush block to quickly style the hair. The axial hole the brush block is open at its outer end. The handle is not round so that it can be more easily gripped and rotated to wind hair therearound.

Abstract: This invention comprises a control for moving a headstock longitudinally on a radial arm of a radial drilling machine and for moving the radial arm angularly about the axis of rotation, by moving the headstock a predetermined distance along an X--X axis and also moving said headstock a predetermined distance along a Y--Y axis at right angles to the X--X axis, for bringing the axis of the drill spindle on the headstock from one drilling position to another drilling position. One Servo motor moves the headstock on the X--X axis and another motor moves it on the Y--Y axis. The motors may be programmed to move said headstock automatically. When the headstock is moved on the radial arm along the Y--Y axis, angular movement of the radial arm is accompanied by movement of the headstock longitudinally of the radial arm. Thus, the movement of the headstock along X--X and Y--Y axes, also moves the radial arm angularly.

Abstract: This pull out sofa bed is an improvement of the sofa bed disclosed in U.S. Pat. No. 3,984,883 dated Oct. 12, 1976 and assigned to the assignee of the present application. In said patent bed there is in effect a lost motion during which no work of compressing the mattress is being performed while slack is being taken up. Consequently the work required to compress the mattress and create the necessary locking of the compressed mattress, is concentrated over a relatively short part of the closing cycle of the folding of the bed. The result of this is that a relatively high "peak" force is required at this portion of the cycle to close the bed and compress the mattress and lock the bed in closed position, thereby requiring exertion of considerable strength by the person closing the bed. The patented bed is satisfactory when the mattresses were made of polyfoam.

Abstract: This application embodies a dual purpose projection screen comprising a layer of milky white, translucent, flexible plastic film, coated on one side with a layer of reflecting metal, and a layer of flexible, white opaque material covering the metal reflecting layer. This screen serves as a high gain reflection screen for rays projected against the exposed side of the translucent film, with such rays passing through said translucent film and being reflected back by the metal layer, and as a standard reflecting screen for rays projected against the exposed side of the opaque layer, with said exposed side acting as the reflecting surface for such rays. Said opaque layer also acts as a backing or strengthening layer for the screen to enhance the strength, handling and mounting of the screen on a frame. This screen can be embossed with fine lines running in the same direction in a pattern, to resemble brushed silk.

Abstract: The knob comprises a body which cannot turn the control shaft unless the body is first pushed in. A brake prevents turning of the knob body when the body is in normal condition. Upon pushing the body rearwardly, the brake is disengaged to allow turning of the knob. Upon releasing the body, spring means projects the body forwardly back to normal condition in which the brake prevents the body from turning. Spring pressed balls allow the body to turn without turning the control shaft upon exerting excessive torque on the body to thereby prevent damage to the controls. Means is provided to limit turning of the control shaft to a predetermined angle.

Abstract: The dashboard of the automobile has an opening through which a tubular casing projects behind the dashboard. On the casing is a bell having a tubular extension telescoped on the casing. The bell, its extension and the casing are clamped to the dashboard. A trigger is pivoted to the tubular extension and has a hammer to strike the bell, a trigger finger projecting into the casing, and a spring to bias the hammer against the bell. Slidably and removably mounted in said casing is a push-pull unit comprising a plug telescoped within a sleeve and adopted to be moved forwardly relative to the sleeve to compress a coil compression spring between the plug and sleeve.

Abstract: This packet is so constructed as to prevent formation of liquid blisters at sealing areas, which are potential break points and which reduces the shelf life of the packet and does not look good and can cause loss of sterility. The packet has opposed walls which are sealed together at opposite sides and at one end, leaving the other end open for injection of liquid. The open end is lastly sealed. Capillary action of the liquid along the insides of the side seams of the packet can often reach the lastly sealed open end before sealing is accomplished, to cause a blister or weak point which can rupture. The present packet is provided with breaks in the side seams and below the top seam to delay capillary action of the liquid along the inside of the side seams from reaching the open end of the packet before said open end can be sealed, thus preventing formation of liquid blisters at the last sealed area of the packet.

Abstract: In this assembly the lockring is made from a flat metal strip crimped at regular intervals to curve the strip into a band. The ends of the band are riveted together to form a circular lockring. This lockring has spring fingers which alternate at different angles from one side of the lockring to grip a flange of a wheel tire rim. The lockring is fixed to a metal trim ring which underlies the outer flange of the wheel tire rim. The attached together lockring and trim ring are assembled with a molded plastic wheel cover by pins on the wheel cover passing through spaced openings in the attached together lockring and trim ring, said pins being either headed over or receiving push clips applied thereto.

Abstract: This pan is made from a single blank of cardboard, cut-scored for easy folding into pan form. In one form of the invention the folded pan is glued to hold its folded or set up shape. In another form of the invention, the blank can be folded into pan shape by the user and held in such shape by applying a piece of adhesive tape. The pan comprises a rear box which is open at the front and has a bottom wall, side walls, a top wall and a rear wall. It also has a bottom portion extending forwardly from the bottom wall, beyond the front open end of the box. The bottom wall of the pan is placed on the street and the waste is shoveled onto the extension and into the box which can then be disposed.

A wire wheel basket overlies the front of the wheel cover and is held between an outer annular flange on the cover and the outer annular wall of the cup in assembled relation thereto. A decorative spinner simulating member fits into the center cup and is fixed to the mounting plate.

Abstract: The seating furniture comprises a seat part and a back part disconnectably connected thereto in condition for use and to allow the furniture to be packed more compactly by the manufacturer for shipment to the retailer with the back part disconnected from the seat part and overlying the seat part. The furniture may be either a club chair or sofa or a rester or a lounger. The hardware comprises a mounting member connected to one of said furniture parts slidably received in a slot or channel or passage in a channel forming member connected to the other of said furniture parts, and having a resilient tongue adapted to snap into a hole in said mounting member, to limit relative sliding movement between said mounting member and channel forming member to hold said furniture parts in assembled condition for display or use. Said furniture parts can thus be assembled by the retailer when received in disconnected condition from the manufacturer.

Abstract: This pull-out sofa bed comprises a metal bed provided with a head section that can be raised to T.V. position, and releasably locked in such position, or released from such position and lowered to sleeping position, or folded over an adjacent long intermediate section of the bed to underlie the foot section of the bed folded thereover and also over said intermediate section, for compactness when shipping the bed. This bed has rear legs foldable underneath the intermediate section when the bed is fully collapsed, and also has means contacting the underside of the collapsed rear legs, to support the folded bed in a plurality of selected vertical levels of the sofa seat when the pull-out bed is collapsed and used as a sofa. The bed has means for locking the foot section of the bed to the intermediate section, in the folded or collapsed condition of the bed, to compress the mattress, which means is highly simplified and easy to manufacture.

Abstract: This is a multi-cylinder engine with a main piston and an auxiliary piston in each cylinder. The main piston is operated by means of compressed gas as a propellant. The auxiliary piston is operated by a hydraulic system controlled by movement of the main piston, and by a valve in the hydraulic system also controlled by movement of said main piston. The engine can have four engine cylinders. Compressed gas is sequentially applied to the cylinders for about 90.degree. rotation of the crank shaft for each cylinder. The angular degree of rotation of the crank shaft during which compression gas is delivered to the individual cylinders can be varied while the engine keeps operating. Liquid gas vaporizes to gaseous state for use in the engine.

Abstract: This doll has means to simulate the sound and feel of a kiss. One arm and hand of the doll, made of elastic or resilient plastic material, constitutes a bulb connected by a tube sealed to an opening at the mouth and between the lips of the doll. In the tube is a reed through which air passes in a direction toward the opening, without sounding the reed, when the arm is squeezed. The lips of the doll can then be pressed against a persons cheek, and pressure thereafter released from the arm to allow the bulb to expand, to create a partial vacuum causing the cheek to be drawn and held to the lips in the manner of a vacuum cup. Upon thereafter pulling the doll's head away from the cheek, a suction feeling is created, simulating the feel of a kiss, and air rushes through the opening and back through the tube to said arm, to sound the reed, thus simulating the sound of a kiss.
