N-chlorothio ureas are produced by the reaction of sulfur dichloride and an urea having at least one hydrogen substituted on an urea nitrogen atom in the presence of an acid acceptor. The N-chlorothio ureas are useful intermediates in the preparation of pesticides.

A hot chocolate dispenser having separate water and chocolate syrup circuits with a syrup and water control assembly connected to the circuits to enable the customer to select a large or small drink while maintaining a fixed ratio of water to syrup. A reverse flow sensor can be used in the dispenser to sense an outof-syrup condition. The sensor indicates backflow of fluid and actuates circuitry to activate a suitable response.

An article-sorting conveyor system is provided in which articles are identified by type as they randomly enter the system and are thereafter selectively removed from the system by type and quantity at one or more diverting stations. This permits pre-set ''''orders'''' for given quantities of given types of the articles to be filled at each diverting station. The article carries an identifying code, such as a binary code, which is read when the article first enters the system to give an article identification signal. This signal passes down the system through a series of shift registers, or the like, at the same rate as the article moves down the system. The article identification signal is checked at each diverting station, and, if the identified type of article is necessary for the predetermined quantity of articles at that station, the article is diverted and counted; if not, the article continues on the conveyor. Once diverted, the article identification signal is deleted from the system.

A method of forming a wire terminal and attaching it to a thermoplastic support member for a coil form. The terminal is formed from a continuous piece of wire by bending one end of the wire into a modified U-shaped configuration having one leg of the U-bent intermediate its length to extend at right angles to the other leg and severing the wire configuration from the continuous piece of wire. The wire configuration or terminal is then transported in supporting contact with a pair of electrodes to a position adjacent a thermoplastic support member. The terminal is heated by means of electrical current passed through the electrodes. While hot, the terminal and the thermoplastic support member are brought into engagement with each other to embed the bight portion of the terminal in the thermoplastic material by fusion of the thermoplastic material due to the heat of the terminal. The electrodes are then removed from the terminal leaving the terminal embedded in the thermoplastic support member.
摘要:
There is disclosed an emergency support for a structure such as a mobile home of the type normally having wheels on opposite sides thereof, adjacent the back thereof, and a structural frame on the bottom thereof, which frame normally rests on piers which support the mobile home above the ground. The present emergency support includes a base member adapted to contact the ground, at least one leg connected to the base member and extending upwardly for attachment to the structural frame of the mobile home, adjacent the front thereof, at spaced points on opposite sides of the longitudinal centerline thereof, and a pair of legs connected to the base member and extending upwardly at an acute angle relative to the ground for attachment to the structural frame of the mobile home, intermediate the front and back thereof, whereby the emergency support provides a third support point, together with the beforementioned wheels, in the event the mobile home falls from the piers.
