Abstract: A hoist device is pivotally attached to a specially adapted rear bumper of a conventional pickup truck. The hoist comprises a generally yoke-shaped frame adapted to wrap around the rearmost ends of the truck's cargo bed such that the hoist, when not in use, will not substantially interfere with the use of and access to the cargo bed.

Abstract: A self contained alarm device is disclosed for aiding in the prevention of the theft of articles from an automobile, such as a citizens band radio, by sounding an audible alarm in the event of an attempted theft. The device includes a box or container in which the article to be protected is mounted and at least one switch mounted on the outside of the container for articles, and at least one switch between the container for the articles and the lid for the container so that removing the container from the surface on which it is mounted will cause an audible alarm to be sounded. One embodiment of the device also includes an electrically conducting wire forming a loop outside of the container for encircling an element of the automobile such as the steering column so that if the loop is cut, the audible alarm will also be sounded.

Abstract: A rotatable print disc is mounted on a carrier which traverses along the print line. The disk is moved from each character position to the next by the shortest distance and it is stopped at the time of printing. The carrier is moved from one print position to the next at a speed which is selected depending on the time required for the disk to rotate to the next character. Printing takes place with the carrier moving at one of a number of speeds. The force utilized to drive the hammer to print the characters is varied dependent on which character is being printed. Hammer firing for each character is timed dependent on printing speed and upon the force utilized to drive the hammer.

Abstract: A method of forming a collagenous article comprising mixing a dispersion of collagenous material with an ester of alginic acid, forming the article, and rendering the mixture sufficiently alkaline for sufficiently long to set the mixture.

Abstract: A method and apparatus for detecting theft of television sets from motels and similar establishments which provide unattended television sets and service as a convenience for customers. The invention uses existing trunk lines utilized in a master antenna television system (MATV) for transmitting television signals to the sets, and does not require installation of additional conductors. A source of low 60 Hertz voltage is applied to each of the trunk lines, and there is associated with each television set a resistor. When the connection of a set to a trunk line is disturbed, the disturbance is detected as a change in resistance and the level of 60 Hz current flowing through the trunk line is caused to change. This change in current is detected at a central location to create an alarm condition. An audible alarm is also created at the location of the television set which was disturbed.
