Abstract: This invention involves an adjustable divider for vending machine helix discharge units. The units are used to store and dispense packaged objects such as chip products, candy, mints, chewing gum, candy bars, cigarettes, cigars, etc. The unit basically comprises a large rotatable helix dispensing spindle having a central divider within the convolutions of the helix which can be adjusted from horizontal to vertical and which divides the helix into separate side by side compartments. The size of the compartments is determined by the position of the center divider, the two compartments being largest when the divider is vertical and smallest when it is horizontal. The compartments are varied in size to accommodate different size packages.

Abstract: Universal window structure which may be used as a single hung window, as a hopper window and as a right or left hand glider window without alteration is disclosed. Mulling means for securing a plurality of the window structures together, retaining clips for securing a screen thereto, false muntin structure, hurricane clips and piggyback storm window structure therefor and window trim structure for use therewith are specifically disclosed along with unique glazing strips, an insert for supporting sash balance structure, sealing strips and corner inserts, sash pivot structure, lock structure, sash guide and tilt release structure and hopper lock means for retaining the window sash in a plurality of separate tilted hopper positions. The frame of the window structure is constructed to permit rapid, accurate assembly with a minimum of low tolerance parts and to this end includes frame jamb adaptor extrusions.

Abstract: A process for the resolution of optical isomers of racemic lithium pantoate by selective crystallization from a solution in methanol, ethanol, or other polar solvents, or by electrostatic separation. The optical isomers can be readily converted to optically active pantolactones which are the starting material for the preparation of optically active pantothenic acid and its salt and pantothenyl alcohol. One of the two optical isomers of each of these compounds possesses vitamin activity. The unwanted or inactive optical isomer of lithium pantoate as such is thermally stable and can be racemized by heating in the presence of a basic reacting compound at a temperature between 120.degree. and 180.degree. C to produce a racemic mixture which can then be subjected directly to resolution without conversion to some other derivative in accordance with the processes of the present invention to produce the desired or active optical isomer.

Abstract: Universal window structure for use as a single-hung window, a hopper window, or a right or left-hand glider window and having a box frame and at least one movable sash is disclosed.An improved mull cover for securing a plurality of the universal window structures together, sash guide and tilt release structure for permitting tilting of the movable sash out of the plane of the window structure, and sash guide and pivot structure for the movable sash are also disclosed, together with an improved sash balance shoe, improved locking structure for the movable sash, improved glazing structure, improved weather stripping, structure for maintaining the weathertightness of the window structure during high winds, and a combination screen retainer and movable sash seal. The window structure of the invention may be installed from the inside of a window opening by means of unique installation clips and can be installed from the exterior of a window opening in conjunction with a unique installation bracket.
