Abstract: ABSTRACT        In automatically filling and sealing pouches at high speed, a pouch supporting base continuously and non-stoppably travels on a conveying path passing a pouch dropping operation station, a filling up operation station, a sealing operation station and a supporting base collecting station in turn.  In the pouch dropping operation station, pouches are dropped into the pouch supporting base after being opened one by one.  In the fil-ling operation station, a fixed amount of substances fills the pouches through the rotary filling up apparatus from the opened filling up mouth of the pouches held by the pouch supporting base.  In the sealing operation station the filling up mouth of the pouches is hermetically sealed by the sealing operation sys-tem apparatus.  In the pouch supporting base collecting station, filled up pouches held by the pouch supporting base are suspended and conveyed, and the empty pouch supporting bases are collected and returned to the pouch dropping operation station.

Abstract: DRIVER CIRCUIT FOR USE WITH INDUCTIVE LOADS OR THE LIKE      Abstract of the Disclosure An integrated circuit is operative to produce an output current to a load and for switching the output current when a predetermined peak magnitude of load current is reached to a lower predetermined constant value.  The circuit includes an internal power stage rendered conductive for producing maximum load current through the external load which is connected in series therewith in response to an internally generated reference current.  The power stage comprises a multi-emitter power transistor with each emitter coupled to a respective emitter ballast resistor such that the load current through one of the resistors may be sensed and compared to the reference current to cause the magnitude of this reference current to be switched from a maximum value to a minimum value when the sensed current is representative of te peak magnitude value of current to thereby reduce the load current until the magnitude thereof is representative of the lower level of reference current.

Abstract: Abstract The invention relates to a cleanable sampling valve to be incorporated into the product line supplying the samples. With such a valve it is ensured that repeated sampling during one long-time product charge passage will take place under optimum sterile conditions and any entrainment of product into the sealing area and the consequent risk of reinfection emanating from that area will be precluded. In addition to that, it shall be ensured at all events that no intermixing of the product of the product sample with cleaning  or disinfecting agent will be possible. The sampling valve includes, inter alia, a closing element(5) having the form of a hollow cylinder and being prestressed against a housing seat surface (3a), the cylinder bore (15) of said closing element(5) being open to a spring housing and stuffing box shell (4) in the closed position of the sampling valve and being closed in the open position through a controlling clearance (22) by means of a lower valve stem seal (23) while controllable relief bores (18a) connect the interior of the spring housing and stuffing box shell (4) to the atmosphere (Fig. 2).

Abstract: ABSTRACT OF THE DISCLOSURE           The disclosure concerns an integral weigh wrapper for wrapping products in stretch film, by weighing each product as it is placed on an infeed support surface, and feeding successive weight signals to a data processor.  Successive signals are compared, and when a stabilized weight signal is received, as determined by the successive comparisons, the data processor produces a start signal which activates a drive motor to rotate one revolution.  This initiates one cycle of operation of the weigh wrapper, in which the product is advanced from the infeed station to the wrapping station, a wrapping cycle is initiated for any product then in the wrapping station, and a previously wrapped product is advanced to a printing and labeling station--where it is automatically indexed, a printed label pneumatically applied to a selected location on the wrapper, and the wrapped and labeled product outputted.

Density modulation forms the beam into high-density moving bunches of electrons.  An axial drift tube encloses the beam, extends to a collector, and is interrupted by a gap.  A coaxial resonant cavity is provided about the drift tube, and there is induced in the cavity a VHF, UHF or microwave output signal corresponding to the modulating signal but with an output power of at least a kilowatt.

Abstract: ABSTRACT     In a method for cytodiagnostic investigation of epithelial cells contained in a sample for investigation, the cell suspension to be investigated is placed in the first bore of a sample chamber containing a plurality of bores disposed parallel to one another and subjected to a centrifuging process. During the centrifuging process, the sample fluid is separated into a proximal layer and a distal layer, and the proximal fraction is then separated by the centrifuging process so that it is transferred via a flow connection provided between the first and second bores, into the second bore. In addition to automatic separation of the proximal and distal fractions during the centrifuging process, it is also possible to perform a staining procedure during the centrifuging process. The result of the process is a slide, having at least two different slide fields, whereby the slide field associated with the first bore is coated with the epithelial cells to be investigated and then stained, while the slide field associated with the second bore is stained as a control field, likewise during the centrifuging process.

Abstract: ABSTRACT OF THE DISCLOSURE    A liquid pump is provided and particularly a downhole pump for use in an oil well bore for pumping oil or in a gas well for removing condensate.  The downhole pump includes a plurality of pump and transfer modules, each of which has an elongate housing with end couplings and with two internal gas passages and a liquid passage extending therethrough.  The pump module further has a bladder extending between the end couplings around the internal passages with the couplings having passages connecting one of the internal passages to space on one side of the bladder.  When fluid, preferably gas, under pressure is supplied through the coupling passages, the bladder forces liquid therein upwardly into the next module.  At the same time, fluid under pressure is exhausted through the coupling passages of the next pump module, aiding it to receive liquid from the pump module therebelow.  The transfer modules supply the liquid up from a lower pump module to an upper one and connect the fluid passages to enable the fluid to operate the bladders.  The components of the modules have several improvements over those disclosed in the parent application.  The internal com-ponents also are all supported from the upper end so that they can expand toward the lower end.  The elongate housings, including threaded end connections, are now of one-piece construction.  The pump also includes a wellhead unit and a bottom unit.

Abstract: Abstract:            A method and apparatus for preparing a proof or sample of an ink (as herein defined) as a preliminary to its being employed in a printing or coating process to enable its colour and coating capability to be determined.  A quantity of the ink is applied to a first roller the surface of which is engraved.  The ink is evenly distributed over the roller using a doctor-blade set so as to wipe the roller surface clean and leave the ink only in the engravings.          A second roller of resiliently deformable material is moved into contact with the inked roller so causing ink to be transferred to the surface of the second roller until equilibrium is reached and a sheet of the substrate to be inked or coated is introduced into the nip between the two rollers.  A unit is provided for cleaning the rollers after use.  The second roller may be formed from two or more separate rollers spaced apart so as to define separate inking surfaces or may be in the form of a single roller having one or more annular grooves to define the different inking surfaces required.
