Abstract: A MULTI-CHANNEL MULTIPLEX DATA                    TRANSMISSION SYSTEM                ABSTRACT OF THE DISCLOSURE      The sum and the difference signals of a pair of data channels are applied to a pair of roll-off filters, respectively.  The outputs of said roll-off filters are modulated by a pair of carrier signals which have the phase difference ? to each other.  The modulated signals are added to each other in an adder and a single output signal is provided from the output of said adder.  Said output signal and another output signal relating to another pair of data channels, and some pilot signals are applied to an adder, the output of which is transmitted to a receiving station in the form of a multi-channel multi-plex data signal.  At the receiving station, the received signal is demodulated with the inverse process of the above modulation steps and the demodulated data signals are applied to an automatic equalizer.  The present invention described above provides high speed data trans-mission through a narrow-band-line which has only almost the Nyquist band width.

Abstract: PROCESS FOR PREPARING METHYL HEPTENONE                     ABSTRACT OF THE DISCLOSURE               A process is provided for preparing methyl heptenone from mesityl oxide or acetone or mixtures thereof in improved yield.            Mesityl oxide is reacted with prenyl chloride to form a ketone mixture comprising mixed prenyl-substituted methyl pentenones, which is then separated from the residual reaction mixture by distillation, subjected to hydrolytic cracking with water in the presence of alkali at an elevated tempera-ture, and methyl heptenone recovered.             The same ketone mixture is found as a by-product of the reaction of acetone with prenyl chloride in the presence of a catalyst to form methyl heptenone. This can therefore be subjected to the hydrolytic cracking reaction, thus increasing the amount of methyl heptenone produced.

Abstract: ABSTRACT OF THE DISCLOSURE           A new mounting arrangement is provided for an inner lamp within a sealed beam envelope.  A ceramic holder is provided in which one or more of the outer surfaces of the holder provide reference surfaces for mounting the inner lamp in a reflector.  The lamp is mounted in the holder using a suitable adhesive, such as basing cement.  The lamp is aligned in the holder with respect to its filament, enabling use of most inner lamps produced that have filaments which are not precisely aligned with their envelopes, thereby increasing the yield of inner lamps.  manufacture is simplified since the inner lamp lead wires need only match the current requirements of the inner lamp and adequately match the coefficient of thermal expansion of the inner lamp glass.  An improved sealed beam lamp results, in one embodiment, since higher efficiency halogen cycle lamps can now be utilized, and, in another embodiment, since construction is simplified by using the holder as a filament shield.

Abstract: Abstract of the Disclosure There is disclosed a checkout system for use in a supermarket or other retail merchandise store or the like. The checkout system includes a stand alone label scanner device for scanning data bearing labels on the merchandise items having a discharge area and a bag supporting cart pivotally secured at one end to a pivot member mounted on the floor remote from the discharge area of the scanning device for supporting bags in an open position to receive merchandise items.  Associated with the bagging cart is a counter shelf member pivotally attached to the cart.  Slidably mounted on the shelf member is a shelf extension member.  In one mode of operation the cart is positioned adjacent the discharged end of the scanning device to allow the checkout operator to move in one motion the merchandise items past the scanning device and into a bag located on the cart.  In a second mode of operation, the cart is pivoted away from the scanning divide where the counter shelf and its extension are moved to a position engaging the scanning unit to allow a bagger operator to continue to receive items from the scanning unit for loading into the same bags.  The use of a bagging cart which can be selectively mounted on the floor in any position with respect to the checkout area allows the arrangement of the checkout area to be varied depending on the overall checkout system desired.

The first valve section includes means establishing free fluid communication between the injector and the fluid port, the second section including means sealing the passage portions from one another and from the exterior, and the third section including means communicating the fluid injector to the exterior.   The valve prevents creation of a vacuum internal of the fluid injector which hinders the withdrawal of the plunger in the fluid injector while coupled to the tap fitting.  The valve also blocks just injected fluid material maintaining it within the cable and under pressure, which permits the subsequent injection of additional fluid material without loss of pressure interior of the cable.

Abstract: INVENTOR Walter H. Wesner By Thomas W. Brennan TITLE: MANUALLY OPERATED, TRIGGER ACTUATED DIAPHRAGM PUMP DISPENSER ABSTRACT OF THE DISCLOSURE: A manually operated dispensing device for a container holding a quantity of liquid is disclosed. The device has an internal chamber and a flexible, elastomeric diaphragm-like cover on at least one side of the chamber in a component re-taining body. Associated inlet and outlet valves, which valves may be separated or integral with the diaphragm and body, and conduits are included whereby liquid from a supply there-of in the container is drawn up into the chamber when the diaphragm is flexed under stress. The diaphragm is operatively associated with a trigger device, the actuation of which flexes and stresses the diaphragm in a direction to decrease the chamber volume. Liquid which is present in the chamber is displaced and pressurized in a pumping action, forcing the outlet or discharge valve to open and the inlet valve to close allowing the liquid to flow into the outlet or discharge conduit and be dispensed from the device in a spray. Alternate application and relief of the above described flexing or stressing action of the diaphragm by alternate actuation and release of the trigger causes the inlet and outlet valves to alternately open and close, draw liquid into the chamber and dispense it therefrom.

Abstract: ABSTRACT OF THE DISCLOSURE             Reaction of laser radiation and a reactive medium is conducted by reflecting a hollow conical beam of the radiation back and forth between two aspheric mirrors.  This gives a long path length for the radiation passing through the medium, although the length of the reaction zone, i.e. the distance between the mirrors, may be comparatively small.  By selection of the curvature of the mirrors, the radiation flux density can be controlled so that it is substantially uniform or so that it exhibits a pre-determined cylindrically symmetrical variation across the width of the reaction chamber, and this distribution of the flux density can be matched to the dis-tribution of availability of reactive species within the re-action zone.  In many practical  applications, such as laser isotope separation, photon-enhanced chemical reaction, laser amplification, or laser resonance, the reactive species will be distributed uniformly within the reaction zone or will be distributed to a varying degree across the width of the re-action zone, this variation being cylindrically symmetrical. By matching the flux density to the availability of the reactive species, the efficiency of the reaction can be increased.

Abstract: 26.9.1977 ABSTRACT:         When absorption values in the individual image points of a planar slice to be examined are reconstructed from measuring values, which have been determined with the aid of a transversal tomography scanner, artefacts may be produced when the body being measuring moves relative to the coordinate reference point of the scanner during the measurement.  In order to avoid such artefacts, the measuring values thus determined are shifted relative to their coordinates in such a way as though they were obtained from a non-moving body. For this purpose the weighted-mean point is determined for each series of measuring values  determined for each specific orientation of the measuring beams, and for all weighted mean lines which pass through said weighted-mean point perpendicularly to the measuring coordinates the distance to a point of the image plane is subsequently determined.          Next, the measuring values are shifted or processed in a shifted manner in conformity with said distance.
