Abstract: An apparatus and a method for the production of frozen confections wherein the frozen confections are produced from a supply of a generally semifrozen confection material of viscous consistency conveyed at a constant volume and at a constant rate through a novel filling system into a plurality of molds. The apparatus provides for the production of frozen confections from a supply of a generally semi-frozen, compressible material having a highly viscous consistency, wherein the material is rapidly and accurately metered into "bottom-up" molds which are indexed into position below a filling station, and in which filling nozzles are inserted into the molds so as to fill the latter with the material to the desired extent as the nozzles are raised upwardly out of the molds.

Abstract: The present invention provides an accurate method and apparatus for monitoring the drop flow rate from a fluid source. The method and apparatus allows for an intermittent drop flow rate by accumulating a weighted drop period rate error factor which is adjusted for each drop period detected.A drop period window is adjusted by each drop period and is utilized to determine if the current drop period is within the window indicating a normal operation. Drop periods outside the window cause a factor to be added to the accumulated error factor and drop periods within the window cause a factor to be subtracted from the accumulated error factor. This allows good periods to offset bad periods, so that minor fluctuations in the drop periods during normal operation can be ignored.

Abstract: An adhesive applicator has a nozzle through which adhesive can be dispensed to sheets of a set as the sheets are driven seriatim past the nozzle. Adhesive is furnished in a cartridge which is pressurized so that the adhesive is delivered from the cartridge to the nozzle under pressure. A valve controls the flow of adhesive from the nozzle, and the valve is under control of a logic and control unit. The logic and control unit receives signals from various sensors or detectors indicating, inter alia, the presence of an adhesive cartridge, the level of adhesive in the cartridge, the flow of adhesive from the nozzle, and the amount of adhesive in a collection bottle which receives surplus adhesive dispensed from the nozzle but not applied onto a sheet. The logic and control unit is capable of operating the valve that controls flow of adhesive from the nozzle so that adhesive is selectively dispensed from the nozzle to all but one sheet of a set of sheets.

Abstract: A dispenser for drawing toothpaste from a squeeze-tube container and applying it to the top of a toothbrush with a vacuum pump of piston-cylinder construction which is so operated that the pump draws the toothpaste out of the squeeze-tube container when the toothbrush is pushed into the dispenser and discharges the same when the toothbrush is withdrawn. The toothpaste is pumped through a passage which is provided with an inlet valve which operates in cooperation with an elastic adapter used for mounting and sealing the neck portion of the squeeze-tube container, an outlet valve which operates in cooperation with a port formed in the cylinder, and an elastic discharge nozzle which opens when the toothpaste is being pumped and closes by its own resiliency when the toothpaste is being drawn out of the squeeze-tube container. The amount of toothpaste supplied each time by the dispenser can be adjustably predetermined as desired.

Abstract: This device for rapid and extremely accurate filling of containers includes a duct for bleeding off gas bubbles from a metering device, where prior bubble-eliminating provisions are inadequate due to extreme product viscosity. The device also has relative adjustment between a positive mechanical stop, used to define very precisely the substance volume metered by a biacting piston, and a control switch used to reverse the piston. This adjustability corrects an inaccuracy arising in prior devices due to the necessarily slower speed of the piston with extremely viscous product.

Abstract: A plurality of arcuately spaced transceivers for emitting and receiving radiation waves are positioned in a plane transverse to a molten metal stream. Each transceiver emits a radiation wave which is directed toward and reflected from the stream and the reflections are received by the transceivers. The time elapsed between the emitting and receiving of the radiated waves is measured for each transceiver. The time elapsed information is fed to a binary counter for each transceiver and the binary counts are averaged and processed in a computer to calculate the stream area. The rate of change in area of the stream in the transverse plane is determined, or alternatively the velocity is determined by measuring the time elapsed for a particular stream area to traverse a predetermined distance and fed to a computer which computes stream velocity. The velocity and area measurements of the stream are used to determine the stream volume. A programmed pour rate is then compared with the stream volume.

Abstract: A digital system wherein a wide variety of different electromechanical output control devices, e.g., stepping motor pump or solenoid actuated I.V. tube pincher, is driven by electrical output pulses of varible frequency and pulse width from a digital pulse generation and control system, the frequency and pulse width of the output pulses being selected and controlled by the system to establish drop flow rates with digital precision over an extremely wide dynamic range. Pulse width is determined by the relative states of a pair of digital counters in a digital memory, frequency being determined by a high, preferably non-integral, multiple of the desired drop flow rate. The equivalent of negative pulse width in the digital memory can be effectively utilized to expand the effective dynamic range of the memory for specified types of electromechanical output devices. A start up subsystem temporarily presets the initial pulse rate and speeds up early regulation.

Abstract: A system is provided for monitoring fluid discharged from ships and for determining the amount of contaminants, such as oil, in the fluid. The discharge from the ship is continuously monitored by a meter which will indicate the oil content of the discharge in, for example, parts per million. The indicated value may be charted for record purposes. The total volume of discharge from the ship and the speed of the ship may also be measured. The three values obtained by the foregoing measurements are processed in computing mechanism and a value is obtained for the amount of contaminants being discharged for each unit distance travelled by the ship. When the aforementioned value reaches a predetermined amount, the discharge from the ship is interrupted, or reduced, so that at no time do the amount of contaminants discharged from the ship exceed a predetermined allowable limit with respect to the speed of travel of the ship.
