The Mixobeater was a machine developed for the baking and food processing industries by the Meteor Mixing Machine Company and Mixobeater Machinery Company, of New York.

These photographs show an exhibit sponsored by the New York State Home Bureau Managers' Association that went on display at the New York State Fair in Syracuse from August 30th to September 6th in 1952. The exhibit was intended for use by professionals in the field of home demonstration to showcase principles of home economics and domestic skills to State Fair attendees.

The exhibit was developed under the supervision of Professor Mary Koll Heiner (1890-1956), of the College of Home Economics at Cornell University, and fabricated using Crosley and Bendix brand appliances and cabinets. At the time these photographs were taken, these two brands were produced by the Crosley Division of the AVCO Manufacturing Corporation of Coldwater, Ohio.

The North Brothers Manufacturing Company was an iron and brass foundry that developed an expertise in manufacturing metal kitchen appliances. The records consist of a sample preserved at the time of the company's transfer to The Stanley Works in 1946. The bulk of the records concerns the manufacture of appliances, largely ice cream freezers. In particular, the records relate to the assignment and registration of patents and trademarks under which they were manufactured and sold.

This series consists of papers created by Dr. Schlumbohm that were preserved by industrial designer Marc Harrison and included among his own papers. Harrison augmented the papers with additional clippings related to Schlumbohm and his own photographs of Schlumbohm's products during the 1970s. Most of the material remains in scrapbooks, although some has been removed and rehoused.

The scrapbooks contain correspondence, newspaper clippings, magazine articles, brochures, advertisements and photographs dealing with Schlumbohm's activities and products. The great majority of the pieces deal with the Chemex coffee maker, including rejection letters from companies that Schlumbohm tried to interest in manufacturing it, letters of endorsement from cartoonist Charles Addams, Lyndon Johnson, and Bess Truman, gift catalogs that included the Chemex, and photographs of the Chemex in the famous 1959 American kitchen exhibit in Moscow, scene of the "kitchen debate" between Nixon and Khrushchev.

Other products include the Chemobile, a radically simplified boxy compact car that was the antithesis of the low-slung, voluptuous American cars of the period, the "Mixarium" cocktail shaker, the "Fahrenheitor" wine or beer-bottle cooler, the "Pre-vue" color-correcting mirror, a German water pump, and mobile refrigeration units. There is also material dealing with Schlumbohm's work with dry ice, correspondence relating to Schlumbohm's patents, and candid photos of Schlumbohm and his friends.
