Abstract: ABSTRACT            A marine propeller unit having a propeller mounted on a horizontal propeller shaft which is journalled in a gear housing, which is fixedly connected to a hollow strut whose upper end is mounted in the bottom of a water-going vessel for rotation about a substantially vertical axis.  The propeller is driven by a drive machinery within the vessel.  Two conical gears on the propeller shaft are coupled to two vertical gear-drive shafts journalled within the strut.  The two gear-drive shafts are coupled by their respective cylindrical gears to an inner vertical drive shaft and an outer tubular drive shaft respectively, said tubular drive shaft being arranged outside said inner drive shaft and coaxial therewith.  These coaxial drive shafts are connected together and to the output shaft of the drive machinery by means of resilient couplings in a manner such as to permit said shafts to be driven together.  Because the power to the propeller shaft is distributed between duplicate gears and shafts, the dimensions of the gear housing and strut can be such as to ensure that the propeller efficiency is not excessively reduced, even when high propeller power is required.  By means of torsion ill the coaxial shafts and through the resilient couplings, the power to the gears is so distributed as to prevent them from being overloaded.

Abstract: IMPROVED WATERBED MATTRESS   ABSTRACT      An improved adjustable waterbed mattress with hydrostatic wave absorption comprising a water-inflatable bag-like enclosure containing therein a non-woven or very loosely woven expanded fiber product, unbonded or fixed with a binder to the same or another fiber product, which resists decomposition in water.          When a user sits or lies on a conventional waterbed there is a tendency to sink or bottom out especially on the edge and an undesirable wave front is created in the waterbed mattress.  The provision of the subject expanded fiber product in the waterbed mattress of the present invention substantially mitigates and dissipates this wave front and allows the bed to be easily packaged, filled, heated, drained and stored.

Abstract: ABSTRACT OF THE DISCLOSURE     In a beverage dispenser of the type having a diluent mixed with a syrup to produce the beverage to be dispensed, provision is made for utilizing a relatively high flow rate.  To achieve the relatively high flow rate, a depressurizing system utilizing a vortex chamber is located at the output end of the valve arrangement.  The flow path of the diluent through the valve arrangement before the depressurizing system is designed to minimize pressure drops.  Diluent leaving the depressurizing system has its velocity decreased by a diffusing structure before being passed for mixing with the syrup.  The diffusing system also decreases the swirl imparted to the diluent in the depressurizing system.

Abstract: METHOD AND APPARATUS FOR NON-DESTRUCTIVE INSPECTION OF TIRES               ABSTRACT OF THE DISCLOSURE            A pulsed through-transmission ultrasonic non-destructive inspection of the internal struc-ture in a tire wall is effected.  The transmitted acoustic signals preferably have a frequency of at least 40 Khz, are transduced to electrical form, amplified with a relatively long time constant AGC, rectified and integrated during only the initial or leading edge portions of each pulse or burst. The resulting integrated analog signal values thus pro-vided have relative magnitudes which may by displayed or otherwise processed to detect structural anomalies within the tire wall.  If plural acoustic transmit-ters are utilized, they are preferably multiplexed such that only a single transducer is activated at a given time.  The ultrasonic inspection is preferably carried out through the walls of a rotating inflated tire with the ultrasonic transducers being automa-tically moved toward the inner and outer tire wall sur-faces to optimum relative distances of separation during an inspection cycle.  The transducers disposed inside the inflated tire are preferably mounted for automatic retraction into a protected space during tire mounting and demounting operations. Such ultrasonic inspection techniques may be combined with conventional tire buf-fing methods and apparatus as practiced in tire re-treading operations.

Abstract: ABSTRACT         A concrete mould employs resilient side shuttering, made of rubber for example, which is prevented from deflecting, when concrete is poured, by tensioning wires extending along the length of the shuttering.  Pieces of the shuttering, forming the sides of a casting box, extend between fixed and plates having a series of holes to receive the tensioning wires for adjusting the modular width of panels cast in the box.  A series of apertures is provided in each piece of side shuttering so that pneumatic core formers can be inserted through aligned apertures so as to extend across the casting box.  Different types of joint formers, either fully or partly resilient, can be located about the core formers, each joint former having a series of grooves to receive reinforcement or tensioning wires or rods.  When inflated the pneumatic core former locks the joint formers in place.  Opening formers can be made from the shuttering and joint formers.  Standard reinforcement cages can be located in the casting box at modular position corres-ponding with aligned apertures in the side pieces of shuttering. The modular positions are digitally coded to enable the casting process to be automated by a machine travelling on rails along the length of a casting bed which supports the side shuttering and end plates.  The machine stops at the modular position to locate the respective formers and/or reinforcement cages and it also carries out automatic functions such as cleaning and oiling, laying, packing, screeding and finishing wet concrete.

Abstract: ABSTRACT OF THE DISCLOSURE     The method for the production of an endless reinforced toothed belt of synthetic plastics material, the circumferential length in the untensioned condition is to have a predetermined minus tolerance in relation to an operationally tensioned intended circumference having the exact tooth pitch, firstly produces on a moulding wheel and a tensioner wheel a helically wound wire coil with fixed wire ends, the moulding wheel and tensioner wheel hav-ing an interaxial distance at which the wire coil has the minus tolerance from the intended circumference.  Then the wound wire coil is tensioned with elastic stretching of the wire turns and enlarged to the intended circumference by enlargement of the interaxial distance to the intended distance.  Then with the mould-ing wheel and a moulding belt a closed mould cavity is formed and by injection of synthetic plastics material into the mould cavity beginning a synthetic plastics strand of toothed-belt form is produced into which the wire coil is embedded in the mould cavity.          With one revolution of the wire coil the synthetic plastics strand issuing from the mould cavity end is conducted back around the tensioner wheel into the mould cavity beginning and in the mould cavity the beginning of the synthetic plastics strand is cast with its end.  Next the intended distance is shortened again and the finished reinforced toothed belt is removed from the moulding wheel and tensioner wheel, the elastically stretched wire coil relaxing and contracting the finished toothed belt to the belt circumferential length with the minus tolerance from the intended circumference.

Abstract: Case 2715 MICROPROCESSOR WATCHDOG SYSTEM      ABSTRACT OF THE DISCLOSURE        A watchdog system for a microprocessor uses the primary AC power source to initiate restart signals for the microprocessor.  The microprocessor has an internal checking system which checks one or more memory locations for specific numbers or codes which are present in normal operation.  Other additional checks may be made.  If the check is satisfactory, the microprocessor provides a reset signal at regular intervals.  A counter is coupled to the    primary AC power source and it counts the pulses it receives until a predetermined count is reached.  The counter then provides a restart signal.  The counter is reset by the reset signal from the microprocessor when the check is satisfactory, and the time interval between reset signals is shorter than the time required for the counter to count to the predetermined count.  Thus, when the microprocessor check is satisfactory the counter is repeatedly reset and it does not reach the predetermined count.  If the counter does reach the predetermined count, it provides a restart signal which initiates the restart procedure of the micro-processor which places any required numbers, codes or other data in required memory locations.
