Title: Vending machine antirocking plate
Inventor: MCGARRAH ROBERT G
IPC: G07F9/10
Filed: 1990-08-07
Abstract: ABSTRACT OF THE DISCLOSURE         A vending machine antirocking plate is disclosed which is a safety feature for a soft drink vending machine to prevent rocking of the vending machine.  The antirocking plate prevents oscillatory rocking of a vending machine by a potential pilferer who may attempt to attain a sufficient forward tilt of the machine to possibly dislodge soft drink containers within the vending machine to fall through the product dispensing chute.  A safety problem has been incurred in this situation as the vending machines are very heavy, and can possibly fall on top of and injure the person rocking the machine or other persons in the proximity thereof.  The present invention is designed to prevent such rocking motions by securing an antirocking plate to the front leveling legs of the vending machine and extending forwardly therefrom and overlying the floor, such that a person standing in front of the machine will also be standing on top of the plate.  Accordingly, if the person attempts to rock the vending machine, his weight on the plate will cause the plate to prevent the front legs of the machine from lifting, thereby preventing oscillatory rocking of the vending machine.  In a further disclosed embodiment, the antirocking plate extends fully under the vending machine, and is secured to both the front and rear leveling legs of the vending machine, and thereby prevents both rearward and forward tilting or rocking of the vending machine.  In different embodiments, the antirocking plate can be fabricated from plastic or can be fabricated as a metal plate.  Embodiments of a plastic antirocking plate preferably include metal plate inserts which lock onto the legs of the vending machine.

Abstract: A wheel mounting assembly for a rail-supported storage/retrieval machine (10). The drive (14) and idler wheels (18) are each mounted on a removable module (32, 34) which includes a fixed plate (46) having a concave spherical surface (48) formed in it and movable plate (50) to which the wheel is mounted having a convex spherical surface (52) interfitting with the concave surface on the fixed plate to define a spherical joint. The plates are interconnected by bolts (58) fitting loosely in oversize holes (49) formed in the fixed plate and threaded into the movable plate to provide limited relative movement of the plates about a plurality of axes. Four jackscrews (60-63) arranged in pairs on opposite sides of the movable plate are threaded through a frame (42-45) holding the first plates and bear against the sides of the second plate. Simultaneous tightening and loosening among combinations of the four jackscrews provides horizontal and vertical alignment of the wheel relative to the rail on which the machine is supported. After proper alignment is achieved the bolts are tightened to provide a clamping force between the spherical surfaces.

Title: Anti-wrap for high speed printing press
Inventor: PERRETTA FRANK
IPC: B41F33/18
Filed: 1990-10-24
Abstract: ABSTRACT    An anti-wrap apparatus and method for high speed printing press involves detecting the start of web wrap after web break to deactivate the press motors and apply the press brakes.  In addition the detection mechanism which senses a change in the web path, can sever the already printed web being drawn backwards by the start of web wrap, to limit the availability of web material, for web wrap.  In the case of difficult to sever web materials, severing action can be enhanced by forcing the web being drawn backwards, against the severing detection mechanism.

Title: Single plug arrangement, lock therefor and method of use
Inventor: BRADDICK BRITT O
IPC: E21B23/04
Filed: 1990-11-16
Abstract: SINGLE PLUG ARRANGEMENT, LOCK   THEREFOR AND METHOD OF USE   Abstract of the Disclosure A single wiper (10) is releasably and sealably positioned adjacent the lower end an operating string (not shown) and locked therewith to prevent premature release from the operating string upon manipulation of the operating string.      The sealing relationship between the wiper (10) and the operating string prevents communication of operating string pressure from the operating string to the external resilient ribs (12) of the wiper adjacent the position of the wiper on the operating string. When a pump down plug (45) is sealably seated within the bore (11) of the wiper (45), fluid pressure is confined to act on a piston (P) between the operating string and the wiper (45) to unlock the wiper (45) from the operating string so that it may be released therefrom.

Title: Melt system for spray-forming
Inventor: SAWYER THOMAS F
IPC: C23C4/12
Filed: 1991-01-17
Abstract: A method for regulating the flow of liquid metal to an atomization zone is provided. The regulation is effected by imparting a high density flux to a strew of liquid metal as it descends toward the atomization zone. The high density flux is applied by a flux concentrator. The flux concentrator is a small sleeve-like element attached by parallel conductors to a larger sleeve~like element which acts as a secondary to a primary coil extended through the larger sleeve element. By imparting high density flux to initiate a stream passing through the flux concentrator the cross sectional dimensions of the melt stream and the rate of flow of melt through the concentrator is regulated to values which are appropriate for a spray-form type of action.

Title: Human monoclonal antibodies for brain tumor diagnosis and therapy
Inventor: DAN MICHAEL D
IPC: C12P21/08
Filed: 1991-01-28
Abstract: ABSTRACT         The present invention relates to monoclonal antibodies  directed against neuroectodermal tumors produced  by human  hybridoma  cell  lines.   These hybridomas are produced by the fusion of peripheral blood lymphocytes, obtained from patients with different neuroectodermal tumors,  and a myeloma-like cell line, TM-H2-SP2.   Five hybridomas,  designated as BT27/lA2, BT27/2A3,  BT32/A6,  BT34/A5,  and BT54/B8,  all produced monoclonal IgM in a range of 2.4 to 44 µg/ml, had a similar pattern of reactivity against a panel of human tumor cell lines, and did not react with normal human astrocytes.   All  five human monoclonal antibodies (HmAbs) recognized a subpopulation of tumor cells and preliminary antigen characterization indicated that these HmAbs are directed to cell surface glycolipids. Cell sorting experiments suggest that the identified subpopulation may share certain properties with tumor stem cell.   These HmAbs possess certain properties of reactivity that suggest potential roles for them in the future diagnosis and clinical management of human malignant gliomas.
