Abstract:
The pump has a pumping chamber defined by a stator and by a rotor with a driving shaft. A hopper with a feeder unit is positioned above the pumping chamber and is connected with it. The feeder unit receives its motion from the upper end of the driving shaft through means for the transmission of motion positioned above the pump.
Abstract:
A machine for dispensing liquids, especially for filling cartons at a higher rate of speed, is disclosed. The machine includes three bellows arranged in vertical alignment, with upper and lower sleeves interposed between the bellows. The discharge nozzle is located below the lowest bellows. The upper sleeve moves axially relative to the nozzle to control the opening and closing of the discharge valve. The lower sleeve also moves axially to control the filling and recharging of the bellows directly above the discharge nozzle. The method of operating the components in timed relation to achieve effective and efficient carton filling, as well as draining and cleaning, is disclosed.
Abstract:
The invention relates to a process and an apparatus for the transfer and dispensing of brittle solid particles, the apparatus comprises a transfer and dispensing device including a chamber divided into first and second sections by a transverse partition wall provided with one or several holes, of a diameter smaller than that of the solid particles, the two sections communicating with one another through said holes. The first section is a dispensing section proper, ending at its lower end with an opening defined by the open lower end of said chamber, wherreas the second suction or discharge section, cooperates with a suction and discharge device. The apparatus ensures an accurate proportioning and a high rate of introduction of the solid particles into bottles, reaching 25000 bottles per hour, without damaging them.
Abstract:
A filling station for filling flexible containers with liquid. The filling head is fixed. The container is gripped and brought into abutment with the filling head outlet. The container is filled and subsequently while the container is still in abutment with the filling head it is heat sealed. The container is then removed.
Abstract:
To collect a series of liquid samples each of which has a fixed volume in a corresponding series of sample bottles, a sample collector includes a control circuit that initiates the sampling at preset time intervals or each time a preset volume of liquid has flowed past the collector as indicated by a flow meter. To control the volume of each sample, an optical liquid interface detector within the flow passage of the sample collector initiates counting of the revolutions of the pump and after a pre-selected number of counts, the control circuit terminates the pumping. The optical liquid interface detector includes a light-emitting diode on one side of the flow passage and a phototransistor on the opposite side to detect the interface of the liquid.
Abstract:
A method and apparatus for filling open-top containers with a flowable semi-solid material in which the material is discharged in substantially continuous fashion to a downwardly opening nozzle. An empty container is elevated into partial telescoping relative with the nozzle and moves downwardly as it is filled. The filled container is moved crosswise of the nozzle and the vertical position of the container relative to the nozzle is controlled during movement crosswise of the nozzle to initially maintain the upper edge of the filled container below the lowre edge of the nozzle at its discharge side to shear off material at a level above the top of the container and to thereafter move the filled container upwardly sufficient to cause the trailing upper edge of the filled container to substantially wipe across the lower edge of the nozzle at the discharge side thereof.
Abstract:
A salad dressing dispenser, in the form of a bottle having a top stopper with a depending individual server in the form of a suspended cup into which an individual serving may be placed by tilting the bottle and shaking the contents to insure proper distribution of salad dressing ingredients entering the individual serving cup.
Abstract:
A filling machine for sterile filling of containers such as vials is described in which a moving conveyor brings predetermined amounts of single file, empty, sterile containers under filling nozzles and holds them there until they are filled. The filling machine has a number of nozzles equal to the number of containers, each nozzle having a pumping mechanism in the form of a double-compartment chamber, the two compartments being separated by flexible diaphragms. Pumping means are provided for pumping a predetermined amount of liquid into the second chamber, the amount corresponding to the volume which is to be filled into each container through the nozzle. The diaphragm flexes and in one stroke sucks into the first compartment an amount of liquid from a source which, of course, is the same volume that is pumped out of the second compartment. Then when the pump reverses, this amount is forced into each vial through the filling nozzle. The diaphragm keeps the two liquids separated and maintains sterile conditions. Preferably pumping is effected by a rotating plate connected through a rod and bushing to a plate which moves up and down to effect pumping. The connection is via a rigid rod with a ball and socket joint at each end. The stroke and hence the volume of liquid pumped is varied by lateral displacement of the axis of the horizontal driving plate. Of course check valves are provided in all of the lines so that there can be no back-flow of the liquid being pumped into the containers.
Abstract:
A dispensing and packaging technique for use with fluent, semiliquid foods of the type which must be handled gently to avoid bruising or otherwise adversely effecting the quality of the food product. The technique includes storing a quantity of the food in an elevated supply trough and then pumping the food from the trough, in measured charges, to the packaging containers. The technique includes an arrangement by which the food product advances along a straight line from the trough to the container thus avoiding any tubing bends, pressure variations, etc. which might affect adversely the food product.
Abstract:
A filling head, particularly for liquefied gas cartridges, comprises a body adapted to extend downwardly into the container to be filled, and a base adjustable in position on the body to rest on the upper edge of the container. The body has an inflatable peripheral gasket to form a seal against the inner wall of the container, a liquid inlet conduit with pneumatically actuated valve means, and an exhaust passage formed with a vertical bore enclosing with a small clearance a slidable pistonlike member. When the head is raised by a container on an automatic filling machine, the valve means are opened and after a short while the gasket is inflated, this delay permitting free escape of the burst of gas which appears when the cold liquid contacts the relatively hot container wall, without the said burst actuating the piston-like member. During the subsequent filling operation air and gas may freely flow through the exhaust passage at a moderate velocity without noticeably actuating said member, but when the container is filled, the liquid flowing through said passages raises said member, which causes closing of the valve means.
