Abstract: CONTINUOUS BEVERAGE BREWER                  ABSTRACT OF DISCLOSURE     A continuous automatic beverage brewer is provided for producing a brewed liquid beverage, such as coffee, in any desired pre-selectable amount.  The brewer includes means for supplying a liquid, such as heated water, and a solid particulate beverage ingredient, such as ground coffee, to a mixing duct through which the mixture passes for a time sufficient to effect proper brewing.          A moving filter intercepts the mixing duct so that a fresh surface of the filter is continually presented to the mixture of brewed beverage and spent solid residue of the beverage ingredient to thereby achieve effective filtering.  Preferably the moving filter comprises a continuous belt of filter material, the surface of which moves continually past the output of the mixing duct so as to continually remove the spent solid residue.  When continuously brewing a hot liquid beverage (e.g. coffee) means are provided for maintaining the mixture of the liquid and the beverage ingre-dient at the desired brewing temperature during passage of the mixture through the mixing duct, preferably by disposing the mixing duct within a reservoir containing the heated liquid therein.  Selectively controllable timing means are provided for controlling the supply of heated liquid and solid beverage ingredient to the mixing duct during pre-selectable intervals to produce any desired quantity of brewed beverage, and also for controlling the operation of the filter belt to cause its surface to move past the outlet of the mixing duct when the brewed beverage is being supplied therefrom.

Abstract: METHOD AND APPARATUS FOR GENERATING DUPLEX           COPIES ELECTROPHOTOGRAPHICALLY FROM SIMPLEX ORIGINALS                Abstract of the Disclosure A method and apparatus is disclosed for generating duplex copies from simplex originals.  A plurality of origi-nals are sequentially fed through the copying area of an electrophotographic copying machine during a first pass with a predetermined number of copies being electrophotographically made only with respect to each original appearing at an even number in the sequence as fed to the copying area and with the copies being made on one side of separate sheets of copy paper withdrawn fro, a storage receptacle.  After collection of the sheets of copy paper from the copying area, these sheets are replaced in the storage receptacle and the plurality of originals again sequentially fed through the copying area of the copying machine during a second pass.  During this second pass through the copying area, a predetermined number of electrophotographic copies equal to the number made during the first pass are made with respect to each original appearing at an odd number in the sequence as fed to the copying area with the copies being made on the side of the sheets opposite to that used during first pass copying, these sheets having been previously replaced in the storage receptacle and withdrawn therefrom for a second time during copying.  Through proper orientation of the sheets replaced in the storage receptacle, duplex copies are therefore made from adjacent originals in the sequence of originals as fed to the copying area during each pass.  Provision is also made to either stack the duplex copies or collate the copies into sets.  The apparatus includes a logic control system that enables semiautomatic generation of duplex copies to enhance simplicity of copy machine operation without unduly increasing machine costs and the logic control system can be incorporated both into new and existing copy machines.

Abstract: ABSTRACT      Printing apparatus in particular for performing multi-colour printing operations has a ribbon shift mechanism (Figure 2 and 3) for selectively interposing different trans-versely spaced portions of a print ribbon 23 between a print head 14 and platen (not shown).  The print head 14 is of the impact type and probably, although not necessarily, of the type which moves along the platen to define a print row. When colour printing is required, a ribbon having a plurality of longitudinally extending stripes of different colours transversely spaced across its width is used.  Selection of required portions of colours of the ribbon is performed by moving the head 14 to preselected positions along the print row to engage, for example, a camming mechanism (including cam 21 and follower 28) which moves the shift mechanism the required amount to make the selection.  Selection of the ribbon portion or colour is by program control and in the case of colour printing, the range of colours is increased by superimposed printing of the available colours on the print ribbon.

Abstract: ABSTRACT:     A dual beam spectrophtometer includes a radia-tion chopper and a monochrometer which includes a diffrac-tion grating driven by a stepper motor.  The chopper includes a gate pulse generator which produces gate pulses GS and GR which correspond to period during which radia-tion from the source passes through a sample cell and a reference cell respectively.  A stepper motor drive circuit produces pulses to step the stopper motor which are syn-chronised with the chopping cycle by means of the GR and GS pulses.  The stopper motor is arranged to step an equal number of times in each half of a chopping cycle.  A further condition which is preferably satisfied is that the first pulse of a sequence should start in the opposite half of the chopping cycle from that in which the first pulse started in a previous chopping cycle.  At low steppng rates the motor will step twice in one chopping cycle and then pause for serval cycles berfore again stepping twice.

Abstract: ABSTRACT    A closure cap construction for a dispensing con-tainer, the cap portion thereof being of the type intended to be held permanently captive on the container and having a dispensing orifice permitting selective discharge of the container contents.  The cap portion comprises a body hav-ing an internal, double-helical screw thread adapted to engage a corresponding screw thread on the neck of the container.  In addition, the body has an internal, down-wardly facing shoulder from which there extends a series of molded, integral locking ratchet teeth.  The upper ends of the teeth are joined to the shoulder, and the lower ends of the teeth are exposed and unconnected, and are intended to by-pass a series of cooperable locking ratchet teeth on the container neck.  Also, the root diameters of both the internal thread  and the cap locking teeth are substantially the same, which simplifies the molding of the cap.  The advantages of the present construction over the devices of the prior art are that the shoulder provides a desirable stiffening and strengthening effect to the cap teeth, so as to minimize flexing or deformation thereof.          Also, because the cap teeth are disposed above the level of the cap threads, the teeth do not interfere with the threads as the latter are being "started", this arrangement reduces the manufacturing cost in that it facilitates the use of high-speed, automatic capping equipment after the filling of the containers with the intended product.

Abstract: ABSTRACT OF THE DISCLOSURE          A rotary air compressor includes a rotor which rotates within a housing and controls communication through inlet and outlet ports provided on the housing and compresses air communi-cated through the inlet port for delivery to the outlet port.  The inlet and outlet ports are provided with check valves controlling communication therethrough.  After the rotor rotates through a dead-center position, the check valves in both the inlet and outlet ports are closed.  The rotor then rotates into a position in which the apex seals carried by the rotor wipe across the inlet and outlet ports simultaneously thereby opening a communication path bypassing the apex seals so that the pressure levels in the chambers across the rotor are equalized.  As the rotor continues to rotate, air is compressed and communicated to the outlet port.
