Abstract: A rack consists of plural sections including at least one section having square tubing vertical corner posts and horizontal shelves secured to the posts. Beneath each shelf are guides which grip the top longitudinal edge wires of conventional locker baskets in such manner that the baskets may be slid rearward from the front of the rack and secured against vertical or transverse displacement by pairs of guides. The shelving has a downturned rear flange, which limits rearward sliding of the baskets, and an upturned front flange having rings which may be padlocked to corresponding rings on the baskets. Sections of rack may be assembled by inserting smaller square tubing pieces into the tops and bottoms of the posts of the sections. A coat rack section may be attached to a rack section in similar telescopic fashion. Such coat rack section preferably has a transverse bar at the rear with at least one horizontal bar extending forward from the transverse bar.

Abstract: An organic photoresist stripping composition especially for use with silicon wafers having an insulating layer and metallization on the wafers contains an organic sulfonic acid and 1,2 dihydroxybenzene. The composition also preferably includes a polar or nonpolar, organic solvent. This composition will remove both positive and negative photoresist from wafers without attack on either aluminum metallization or silicon dioxide insulation layers when used to contact the photoresist on the wafers.

Abstract: An automatic electronic musical instrument generates structured and pleasing musical sound patterns from a random sequence. One phase of the random sequence is supplied to a first shift register. A first plurality of outputs from the first shift register is used to control a rhythm oscillator. A second plurality of outputs from the first shift register is used to control a pitch oscillator. A second shift register receives a second phase of the random sequence and the rhythm signal produced by the rhythm oscillator. A programmed control input provides a song structure to the outputs of the second shift register. The outputs of the second shift register are supplied as inputs to a musical frequency generating means which has the capability of transforming dissonant frequency combinations otherwise selected by those inputs to compatible frequency combinations. The musical frequency generating means also receives the pitch signal from the pitch oscillator.

Abstract: For non-invasive diagnosis of conditions subsequent to a medical operative procedure, at the time of operation a "target" is sutured to tissue. Later, by use of an ultrasonic imaging system or other diagnostic instrument, the location of the target can be accurately determined. Thereupon, non-invasive techniques may be used in the target area to determine changes in physiology subsequent to implanting the target. For example, a target consisting of a fused array of small stainless steel balls is sutured to a coronary artery bypass graft. Later, to determine if the bypass graft is patent, by ultrasonic methods the location of the target and hence the bypass graft is determined. Then, using a Doppler-effect flowmeter, flow through the bypass graft may be measured and compared with prior measurements. The marking technique is also believed to be useful in postoperative determination of tumor growth at the locus of said marker.

Abstract: An improvement in oscillatory line transfer switches of the type having mechanical drive between a drive motor and the shafts of two such switches plus a manual mechanical switch to supplement the drive motor and having a third shaft mechanically connected into the same drive which controls a neutral position. An oscillatory switch system is used to switch from utility power sources to emergency power sources when the normal line supply is temporarily not available. This condition is sensed, an emergency generator activated, and, when the latter is up to needed voltage, the line transfer switches are thrown. After normal line voltage is restored, the switches oscillate back to normal power sources. A gear train causes at least two switches to turn simultaneously.

Abstract: An improvement on prior art uses a card having a longitudinal strip of magnetic tape encoded with two separate tracks. One track contains a security code and data as to the number of uses remaining on the card. The other track is a control having signals which are read directly proportional to the speed of movement of the card. The card is inserted in a slot in a machine which feeds the card into the machine, reads the data on both tracks, reverses the direction of the card, and impacts the card with a hole to indicate that it has been used one time. The position of impact is controlled by the number of uses of the card prior to the particular use and the control track. While the card is traveling in the reverse direction the first track is re-recorded with the number of remaining uses and security code at a rate determined by the control track. The invention overcomes a problem of prior systems resulting from factors interfering with precise speed of movement of the card.

Abstract: A bookbinding is provided by plastic studs which fit through holes vicinal one margin of each sheet and strips which are fixed to the ends of the studs. The studs may be formed integrally with one or, in alternating arrangement, with both strips and complementary holes formed in the matching strip or strips to receive the stud ends. Excess stud lengths are sheared and headed to lock the strips and interposed sheets in position. Both strips may be apertured and the studs inserted through the holes in the strips and interposed sheets, both ends of the studs being headed. To facilitate handling, strips may be assembled in cartridges or coils, and studs in rods or coils. For thicker books, strips are formed with flanges fitting behind the page margins. Spine concealing tapes and caps fit over or around the spine edges of the sheets.

Abstract: A torque rod of variable length permits use of a torque wrench in confined quarters since the distance between the wrench and unit being tightened may be readily adjusted. A sleeve with a non-circular hollow receives a hollow stem carrying a ball detent which fits into any of a series of depressions in the sleeve wall. Within the stem is a pin with a bevel on its inner end. By moving the stem, the bevel forces the ball in or out to permit the stem to be moved in or out relative to the sleeve. A cam determines motion of the pin.

Abstract: Two staple-like spring metal parts designated "lock" and "key" are provided to retain an excavating tooth in a holder. The lock part slides into an opening in the holder for the tooth around a reduced diameter portion of the shank of the tooth and thereby prevents withdrawal of the tooth by interfering with the outward movement of a button on the extreme end of the shank. The legs of the lock are biased outwardly by reason of the unstressed shape of the lock. These outwardly biased legs are forced inward by insertion in the opening of a key which fits outward of the lock and forces the legs of the lock inward into locked position, engaging a portion of the shank. When the key is removed, it provides space for outward movement of the legs of the lock and thereby prevents a tendency of dirt compacting in the opening of the holder from preventing withdrawal of the lock.

Abstract: Filler nozzle and valve for products comprising high to low viscosity fluids, with or without suspended solids, particularly useful in filling pouch containers. The nozzle body has a vertical bore and also a side port entering the bore near its lower end at about a 60.degree. angle. The valve piston reciprocates in the bore and seats at the bottom of the bore. Below the seating portion of the valve member is a concave-conoidal non-drip tip.

Abstract: Quilt for use in wheelchairs has a pouch for the feet of the wearer. The back comes up to the back of the knee area. The front fits over the knees and protects the lap. A drawstring tightens the pouch around the knees. An alternate construction splits the pouch into halves so the legs may be spread apart for the comfort of the user. Fasteners permit the halves to be secured together or, alternatively, to secure the front and back together to enclose the halves at the split.

Abstract: An improved sandwich immunoassay for Toxoplasma gondii antigens associated with acute forms of Toxoplasma infection is disclosed. The assay employs either an F(ab').sub.2 fragment of IgG which reacts specifically with such antigens or a monoclonal antibody for such antigens as the substrate layer in the sandwich. The assay is sensitive and, unlike prior sandwich assays for the antigen, is not affected significantly by cross-reactions with rheumatoid factor.

Abstract: A card having a longitudinal strip of encoded magnetic tape is inserted in a slot in a machine which feeds the card into the machine, reads the information on the strip, reverses the direction of the card and impacts the card to form an indentation to indicate a use of the card. The card is initially encoded for plural uses. Each time the card is used, the number of available uses is decreased on the information on the strip and corresponding indentations are impacted on the card.

Abstract: Folded map booklets showing street and street names fit into pockets in the cover of a map holder. The holder may be folded into compactform. In open position, individual sections of the folded map may be selectively exposed. Along the top edge of the holder is a horizontal scale; slidable along the horizontal scale is a vertical scale. Means is provided to pivot the vertical scale out of the way when the holder is to be folded. An index is provided showing for each street the precise horizontal and vertical scale readings where the name of the street is printed on the map.

Abstract: Encoded magnetic strip cards are fed into apparatus which reads encoded data on the card. The card is fed into and out of the apparatus through a passageway defined by a guide which also serves as a mount for mechanical and electronic components. The guide is precisely constructed so that the thickness and width of the passageway are slightly greater than the corresponding dimensions of the card and the card does not jam in the passageway. In one form of the invention the guide is formed of two generally T-shaped, overlapping, interfitting members. In a second form of the invention the guide is formed of two opposed T-shaped side members and two plates relieved at their edges to receive the legs of the side members.

Abstract: For accurate correlation of the punch pins and edge guide for a paper punch or the like, a gage sheet of predetermined length is formed with accurately located holes corresponding to the desired location of the holes or slots to be punched in paper of similar length (e.g., end holes equidistant from top and bottom of the sheets). Such gage sheet may be pre-punched and of a permanent character, or may be prepared by trial and error by adjusting the edge guide until the end holes are equidistant from the edges of the sheet. The punch pins are lined up with the gage holes and then the edge guide is moved snugly against the edge of the gage. The gage is then removed. The edge guide is mounted on a transversely movable slide visible through a window in the platen on which the paper is to rest. Markings for different paper lengths may be permanently displayed on the platen at an edge of the window. Markings on the platen may be affixed by applying thereto a decal having paper length markings thereon.

Abstract: An improvement on commerical machines which bind documents using plastic strips. The punch mechanism may be automatically actuated when the paper sheets are properly aligned on a punch platen or actuated manually at the user's discretion. Distance of the holes from the edges of the sheets may be indexed.

Abstract: An improvement over the prior invention, U.S. Ser. No. 781,697, filed Mar. 28, 1977, now U.S. Pat. No. 4,137,869 wherein was disclosed a platform maintained below the surface waters which are not naturally suitable for production of marine food. Means is provided to supply nutrients to the platform at a controlled rate. The platform is located at such depth that solar or other illumination causes the nutrients to reinforce the natural eco-system, thereby increasing the production of fish which may be harvested as food. A feature of the improvement is that the platform is formed of modular segments which may be independently added or removed as a means for controlling available habitat or for servicing the platform. Further improvements in the controls for nutrients and for maintaining buoyancy are disclosed. Also clusters of tubes having buoyancy means may be secured to the platform to augment production, or may be independently secured at a distance from the platform.
