摘要:
An improved photo display device of the type having a housing with frame and double photograph envelope providing dual photo viewing as presented within the frame, wherein an alternative picture rotating mechanism includes both a manual ratcheting system on one side of the housing and a motor drive or automatic ratcheting system on the other side. Alternatively a unitary housing/frame formation may receive a spindle assembly directly through the front frame which is then secured by side entry and snap-fit of right and left ratcheting knob assemblies.

An installation and storage system for decorative light strings which includes a plurality of track channels for holding successive segments of the light string, such track channels being supportable by snap attachment to pre-positioned snap fasteners, either on a building or in the yard surrounds. A storage rack having opposite end frames and central support is then constructed to receive successive light track channels in snap-fit for carriage and storage.

Contemplated herein is an automated microscope slide antigen recovery and staining apparatus and method that features a plurality of individually operable miniaturized pressurizable reaction compartments for individually and independently processing a plurality of individual microscope slides. The apparatus preferably features independently movable slide support elements each having an individually heatable heating plate. Each slide support element preferably supports a single microscope slide. Each microscope slide can be enclosed within an individual pressurizable reaction compartment. Pressures exceeding 1 atm or below 1 atm can be created and maintained in the reaction compartment prior to, during or after heating of the slide begins. Because of the ability to pressurize and regulate pressure within the reaction compartment, and to individually heat each slide, each slide and a liquid solution or reagent thereon can be heated to temperatures that could not be obtained without the enclosed pressurized environment of the reaction compartment. A reagent dispensing strip having a plurality of reconfigurable reagent modules may also be used.

A device for storage and display of photographs consisting of a housing 14 with front frame and a spindle 62 containing photo envelopes 50 supported mid-way across the front frame. The spindle carries a large number of photo envelopes by heat welding each envelope to the spindle in close spacing. Each envelope contains two photos back-to-back, and rotation, either manually or motor controlled, indexes intermittent display of the successive photos with two photos always in view in the frame.
