Abstract: A security system for a vehicle having an engine compartment covered by a hood, and an ignition switch for operating the engine, includes a common housing for protecting a hood lock and an ignition lock switch. An electric circuit is provided for shorting an ignition coil during periods of non-use of the vehicle to prevent theft of the vehicle, the circuit being disarmed by the lock switch for a sufficient interval of time to permit use of the ignition switch for starting the engine. A lock-up feature within the circuit maintains the circuit in the disarmed state during operation of the vehicle, and automatically rearms the circuit upon retrieval of the ignition key.

Abstract: Liproprotein emulsion system composed of protein, edible oil and other selected food ingredients are proposed and used to replace egg yolk and other natural materials in various food products. New and improved processes are described for the preparation of lipoprotein emulsions in a liquid or dry form for use in cake; protein beverages and other food compositions. These processes include methods to improve the solubility and functional properties of the protein component. The lipoprotein system can be used alone or in combination with egg white or other heat coagulable proteins to be a complete or partial substitute for whole eggs. Examples illustrate the practice of this invention to replace egg yolk in cake, donut, muffin, custard and like products.

Abstract: A method to inactivate the proteolytic enzyme(s) contained in commercial heat stable bacterial alpha-amylase under conditions which retain full alpha-amylase activity. Use of thus purified alpha-amylase enzyme plus surfactants that are approved for use in bread to inhibit firming and improve the keeping quality of bread and other bakery products.
