Abstract: Image-receiving elements and photographic diffusion transfer products providing diffusion transfer transparency images are described.  The image-receiving elements include a transparent support carrying, in sequence, an acid-reacting reagent; a first polymeric timing layer possessing decreasing alkaline solution permeability with increasing temperature; a second timing layer comprising cellulose acetate; and an alkaline solution-permeable and dyeable polymeric image-receiving layer comprising a graft polymer having a polymeric backbone and grafted thereto moieties which provide mordant capability.  The utilization in the image-receiving elements of the aforedescribed first and second timing layers permits the provision of elements which can be effectively processed over a range of processing temperatures and which are adapted to the provision of transparencies which exhibit desired images without the distracting or otherwise objectionable image defects associated with reticulation.

Abstract: Abstract A method and apparatus for handling and applying formed flanged lids to a carton is disclosed.  Inverted lids drop on an upper conveyor belt directly from a forming machine for travel in a first direction.  The lids subsequently drop and flip to the desired upright position on a lower conveyor belt for movement toward a lidding station.  To prevent over-flipping, the trailing edge is guided by a vertical guide plate.  An idler belt is positioned downstream of the second conveyor belt and above the feed path.  A lug on the idler belt engages the leading edge of the lid being transferred from the second conveyor belt.  The lug holds the lid in proper alignment for driving forwardly by abutting engagement of the carton intersecting with the leading edge of the lid.  The idler belt is carried by a pair of idler rollers.  An adjustable brake on one of the rollers controls the drag on the belt to restrain the lid and assure positive lidding action on the carton.  As the carton moves beneath the idler belt, the lid is pro-gressively seated onto the carton.  A second or trailing lug on the idler belt serves to press down the trailing edge.  The next in-line lug is timed to be positioned at the lidding station to intercept the next lid for application to the next in-line carton.

Title: Solar energy collection
Inventor: FRISSORA JOSEPH R
IPC: F24S80/30
Filed: 1982-06-24
Granted: 1983-06-28
Abstract: The invention relates to a solar energy conversion apparatus in which several evacuated, glass tubular collectors are connected together in a liquid circulation system for controlled movement of a liquid between the interior of the collectors and a storage tank. Liquid circulation is controlled by sensors and switches therefor in regulating operation of valves and/or a pump. The conditions for circulating the liquid rely upon (1) sensing a need for energy at the storage tank, (2) sensing solar radiation availability, (3) sensing thermal conditions in the solar collector tubes to avoid high temperature and thermal shock, and sensing a need to withdraw hot liquid and add more. The system is operable in either of two modes herein disclosed: (a) the "continuous batch circulation" mode in which liquid is pumped to fill the tubes, in parallel, and low. temperature sensed below a set point to stop pumping and resume pumping when the temperature in the tubes arrives at the preselected higher temperature, and (b) the "full continuous circulation" mode in which liquid is continuously pumped through the tube collectors, in parallel, continuously withdrawing liquid from the top of the tube while introducing liquid at the bottom of the tube; in either mode, the hotter liquid being removed from the top of the tubes and relatively colder liquid introduced at the bottom of the tubes.

Abstract: PACKAGE SENSING/FILM CONTROL SYSTEM FOR FILM WRAPPING MACHINE              Abstract of the Disclosure A package sensing system provides length, width and height signals to a film control system which selects the width and length of stretch film to be used by a film wrapping machine to wrap the sensed package.  Package width is sensed by spring biased swing arms which activate electrical switches upon deflection by an entering package.  A wide package is indicated if both swing arms are deflected.  The length and height of a package are sensed by a generally vertical downwardly extending lever arm which is pivotally mounted above the package entryway into the machine.  A first electrical switch coupled to the lever arm generates a length signal upon initial contact by an entering package and a second electrical switch coupled to the lever arm generates a height signal depending upon the ultimate deflection of the lever arm by the package.  Two film widths are provided with the narrower of the two being selected for packages which activate neither the width sensing system or the height sensing system and the wider of the two films being selected upon activation of either of those sensing systems.  The length of the film drawn is determined by the length of a measured package with that length being incrementally increased if a high package is sensed.
