Abstract: A prerecorded message is supplied to a plurality of telephone subscriber numbers automatically called in sequence from a local station. Upon placing the call to the first number, another second number is established by changing the first called number by a predetermined increment. In response to the first called number being reached, the prerecorded message is coupled to a telephone line at the local station. In response to the call being either completed or the elapse of a predetermined time during which it is expected that the called subscriber should answer the phone, a signal is derived to indicate that operations for the first party have been terminated. In response to the termination signal, the telephone is repeatedly hung up and picked up automatically until the prerecorded message has been completed and a dial tone has been detected, at which time the second number is called. The device is activated repeatedly in this manner.

Abstract: A fluid control system for master-slave power steering combinations includes master and slave steering units, a pump, a low pressure discharge line from the master unit, a low pressure transfer space in the slave unit and a low pressure return line to the pump. The transfer space receives heated, low pressure exhaust fluid through the discharge line from the exhaust chamber or space of the master unit. The fluid return line is connected to the transfer space of the slave unit to feed the intake side of the pump. Build-up of pressure in the slave unit is prevented. Secondly, the fluid circulated through the transfer space of the slave unit transfers heat generated in the pump and the master unit. The temperature gradient between the master and slave unit is thereby minimized to effect cooling or heating in the system, as needed. Further, build-up or accumulation of air bubbles in the slave unit is alleviated.

Abstract: A multicolor visual display apparatus for stereophonic sound signals is disclosed. The display apparatus includes a conventional three gun color cathode ray tube, having a screen with a plurality of colored phosphor dot triads. Stereophonic signals are coupled to a deflection yoke located on the neck of the tube for producing a pattern on the screen in sympathy with the information content of the channels. The convergence coils and purity rings normally located at the rear of the yoke on a three gun color tube neck are not used. Their absence permits the location of the deflection yoke behind its normal position whereby electrons from any of the guns strike phosphor dots of different colors in different regions of the screen, producing a pleasing multicoloration of the pattern. A coil in the nature of a standard degaussing coil is activated while the pattern is displayed to further enhance this multicoloration.

Abstract: The invention is directed to an apparatus for brewing a beverage such as coffee or tea. A disposable disc-shaped receptacle contains a predetermined quantity of solid beverage material. The flat lower surface of the receptacle contains a plurality of perforations permitting a flow of hot water into the receptacle for brewing the beverage material. The upper portion of the receptacle is a concave flexible membrane. An actuating rod or stick is attached to the membrane for manually flexing the membrane up and down during brewing. The user places the receptacle into a cup of hot water and using the stick, manually flexes the membrane up and down inducing successive positive and negative pressure variations inside the receptacle. These pressure variations suck and expel hot water through the perforations and thoroughly circulate the water inside the receptacle and throughout the beverage material for brewing.
