Title: Liq. ion exchange treatment appts - with automatic regeneration when resin contracts on exhaustion
IPC: B01J49/00
Filed: 1974-05-08
Abstract: Appts is partic. intended for the softening and demineralisation of water and for the removal of undesirable colour or odour. It comprises brine reservoirs, a water treatment tank with the inlet for the untreated water and an outlet for the purified water, a treatment cartridge inside the body and a movable support for this cartridge, mounted on springs. The cartridge contains the ion exchange resins which contract as they become exhausted; the cartridge contracts in length and the relaxation in press. on the supporting plate starts the regeneration process. After a rinse, the resin again comes into operation and the flow of water to be treated is resumed. The regeneration is started simply by liq. press. and does not depend upon electrical or mechanical means.

Title: Alkenyl benzene from alkylbenzenes and butadiene - with alkali metal catalyst
IPC: C07C2/72
Filed: 1974-11-12
Abstract: Improvement on the preparation of alkenylbenzenes by reacting alkylbenzenes with 1,3-butadiene in the presence of an alkali metal catalyst whereby the alkylbenzene is first contacted with the reaction product before reacting with 1,3-butadieno. The contact is pref. made at a point between leaving the reaction zone and the stage where unreacted alkylbenzene is recovered. Particularly by contacting the fresh alkylbenzene with a catalyst after the catalyst separation stage from the reaction product. This method gives improved yield, smaller quantity of catalyst required and simple operation.

Abstract: ABSTRACT OF THE DISCLOSURE           A setting mechanism for a postage meter fox use in a continuous mail sorting and postage imprinting system which automatically weighs  and meters each piece of mail.  The system is designed to rapidly handle a large quantity of mixed mail.  Mixed mail is continuously and synchronously fed in seriatim along a continuous feed path.  Unsealed envelopes have their flaps wetted and sealed.  All the envelopes are stopped at a weighing station where they are weighed, and the postage corresponding to their particular weight is computed.  The determined postage value is used to continuously reset a postage meter which imprints the required postage upon each envelope as it arrives at a metering station.  The actuator banks of the meter are controlled by stepper motors.  The metering and weighing functions of the system are synchronized such that the postage meter will imprint the proper postage upon each piece of mail, despite the fact that several envelopes may be simultan-eously in transit along the feed path.  Overweight pieces of mail are rejected from the feed path prior to their reaching the postage meter station.  Metered and overweight pieces of mall are separately stacked.

Abstract: PERCUSSIVE FLASH UNIT  OPERATING MECHANISM     ABSTRACT OF THE DISCLOSURE           A unique percussive flash unit includes an initially cocked striker and flash unit rotating assembly, which includes a main member with an inclined laterally projecting cam-forming wall having an inclined cam face which engages and cams outwardly a lateral extension of an actuator and striker holding member to operate a percussive flash unit when the cocked striker and flash unit rotating assembly is released by operation of a shutter release member.  The actuator and striker holding member then returns to its initial position, and when the striker and flash unit rotating assembly is cocked during a shutter resetting operation, the lateral extension of the actuator and striker holding member is moved out of the way of the cam-forming wall by the engagement with the member of a portion of the flash unit socket as it is rotated by a portion of the striker and flash unit rotating assembly so the cam-forming wall will not strike the lateral extension.  The actuator and striker holding member includes a shoulder which prevents the movement of the striker and flash unit rotating assembly from its cocked to its uncocked position when a flash unit is not mounted upon the camera.

Abstract: ABSTRACT           An electrophotographic film member is exposed to an image source, such as a cathode ray tube display unit, and the latent image toned to form a transparency carrying a temporary visible image on said film member at a first station.  The film member carrying the temporary visible image is stepwise translated to a projection station where it is projected in an enlarged display upon a suitable receptor surface.  Thereafter, the film member is stepwise translated to an erase station where the toner is removed and the film member made ready for reuse to receive another image.  The first station includes suitable structure for charging the film member, a selectively operable blind or shutter for exposing the charged film member to the image source and an applicator for applying suitable toner from a toner source to the exposed film member.  The toner particles adhere tenaceously but removably to the ex-posed film member without any fixing or fusing process and hence, the toner can be removed from the film member after projection.  During charging and toning, the film member is maintained in darkness.  The transparency is fully prepared, totally within the confines of a lighttight housing.

Abstract: METHOD AND APPARATUS FOR REMOVING NITROGEN OXIDES FROM A GAS STREAM            ABSTRACT OF THE DISCLOSURE      A gas stream containing nitrogen oxides, such as the tail gas from a nitric acid plant, is treated to reduce the nitrogen oxides content thereof.  The method results in the production of an aqueous solution of ammonium nitrate.  In a liquid-gas contact apparatus, the gas stream is reacted, under steady state conditions with an aqueous solution of ammonium nitrate at a pH of about 0.1 to about 3.5.  The gas stream can be further reacted with an aqueous solution of ammonium nitrate at a pH of about 7.5 to about 8.5; and thereafter with water, preferably slightly acidified.  The resulting gas stream of reduced nitrogen oxides content may be safely discharged to the atmosphere without causing air pollution, the nitrogen oxides content being below imposed standards.  Further the in-ventive  apparatus useful for carrying out the above method includes, in combination, a plurality of packed gas-liquid contact zones, serially arranged, with the first of the con-tact zones having an inlet for the introduction of a gas stream rich in the component to be removed, e.g., nitrogen oxides and the last of the contact zones having an outlet for the withdrawal of a gas stream lean in such gaseous com-ponent, each of the plurality of contact zones including an inlet for the introduction of a liquid medium and an outlet for the withdrawal of spent liquid medium and gas, the liquid and gas in each contact zone passing concurrently therethrough; and separator means associated with each of the plurality of contact zones adjacent the outlet thereof to separate spent liquid medium from the gas stream, the gas stream then being forwarded from each contact zone to the next succeeding con-tact zone.

Abstract: S P E C I F I C A T I O N          TO ALL WHOM IT MAY CONCERN:         BE IT KNOWN that I, NELSON CHEUNG, a citizen of the United States, residing at 1508 West Oakton, Arlington Heights, in the County of Cook and State of Illinois, have made a new and useful improvement in STRAP TENSIONING TOOL WITH LOAD-SENSING HANDLE of which the following is a specification.     ABSTRACT OF THE DISCLOSURE            A strap tensioning tool having a feed wheel driven through a tensioning assembly by a load-sensing handle.  The feed wheel and tensioning assembly are mounted in a frame for pivotally swinging from a first position in which tension can be drawn on a strap loop by the feed wheel to a second position in which tension cannot be drawn by the feed wheel and whereby the strap can be inserted into, or removed from the tool.  The load-sensing handle has a drive lever which is rotated to drive the feed wheel by a handle lever pivotally mounted on the drive lever, whereby the feed wheel can be rotated to achieve a certain predetermined strap tension, after which the handle lever overcomes the force of a biasing means between the handle lever and drive lever and moves relative to the drive lever about the pivotal mount until the handle lever contacts fixed stop means preventing further rotation of the handle lever to thus stop the tensioning action.
