Abstract: ABSTRACT     Apparatus for circular surgical stapling of hollow organs comprising an instrument and disposable cartridge.  The instrument comprises a housing with a throughbore in which a tube is received for reciprocation by means of a manually operable squeeze handle.  A rod reciprocates within the tube by means of a wing nut cooperating with a threaded part of the rod.  A two-part disposable cartridge assembly comprised of an anvil carrying part and a staple carrying part are detachably mounted on the rod and housing, respectively.  A key is provided to hold the housing and rod in rotational orientation.  Mutually coacting stops on the tube and rod determine the extent of reciprocation which is variable in dependence upon the position of the rod which in turn is dependent upon the juxtaposition of the anvil carrying part with the staple carrying part when the apparatus is closed on tissue preparatory to effecting a circular anastomoses.

Abstract: PROCESS FOR THE PRODUCTION OF CARNITINE AMIDE               ABSTRACT OF THE DISCLOSURE     Process for the production of carnitine amide in the form of a chloride.  The carnitine ethyl ester is obtained by reaction of 4-chloroacetoacetic acid ethyl ester with trimethyl amine and the subsequent hydrogenation is carried out with the help of a Pt/C catalyst.  Such carnitine ethyl ester, without isolating it, is reacted with ammonia in an autoclave at -30° to +10°C.  Everything is heated to 40° to 80°C.  The mixture is stirred at such temperature at an ammoniac pressure of 8 to 24 atu.  The product is filtered after cooling it to ambient temperature and counterbalancing the excess pressure.  The product is then washed with alcohol and subsequently dried at 30° to 50°C. and at a pressure of 15 to 25 torr.

Abstract: ABSTRACT   An apparatus for measuring a property of a traveling sheet (10) comprises a sensor body (16,30,64) and a target body (14,20) adapted to be located on opposite sides of the sheet and constrained (e.g., by gas bearings formed between 32 and 36 and 38) during the measurement without substantial solid bodily contact for movement along respective portions of a mutual sensor path inter-secting the path of the sheet.  Means (44,46,48,56,64, 70,72,74,76) effective without substantial solid bodily contact normally maintain each of the sensor and target bodies at respective, substantially constant distances from the opposite, nominal surfaces of the sheet while permitting the movement of the bodies along the sensor path in response to the position and thickness of the sheet between the nominal surfaces.  Sheet property sen-sing means, including means (18,84,94,118) aboard the sensor body and means (20) aboard the target body inter-act through the sheet to produce aboard the sensor body a response dependent on the sheet property and produce, without solid bodily connections, manifestations of the sheet property dependent response at a location (at 96) spaced from the sensor body.  Means (24,96) including means (96) at the spaced location detect the manifesta-tions and produce (at 263 a sheet property-indicative response.

Abstract: STABLE POSITIVELY CHARGED ELECTRETS            Abstract of the Disclosure A method of producing charged Teflon material having a stable internal positive charge is shown. Partially penetrating positive ions, which may be produced, for example, by a corona discharge or ion beam, are applied to Teflon at an elevated temperature, typically in excess of 100 degrees Celsius for high stability.  It has been found that stable internal positive charges may be obtained thereby, having a stability at room temperature in excess of 2,000 years in some cases.  This is comparable to the charge stability of negatively internally charged Teflon articles.  Regions of both positive and negative internal charges may be included in the same article.  Various charged Teflon devices may be made, including microphones, loudspeakers, electrostatic air filters, etc.  Intermediate levels of charge stability, less than the maximum obtainable, may also be produced.

Granted: 1986-12-09
Abstract: ABSTRACT OF THE DISCLOSURE          This invention provides a new method of manufacturing pre-fillable hypodermic syringes.  An ampul is formed, filled with medicaments and bonded to the hypodermic needle or is ready for affixation of the hypodermic needle at a later time, all in a single continuous efficient process.  All of the steps and procedures may be accomplished within a single tooling apparatus.  Moreover, the sterility of the contents of the ampul and the sterility of the hypodermic syringe itself is maintained throughout the process.  The method in one form comprises initially the injection-moulding of plastic to form a neck and a parison.  The neck is in final form at the injection stage.  A blow-fill pin is inserted into the parison, and the parison is then blow-moulded into the final, shape of the ampul.  Medicaments are injected into the ampul through the blow-fill pin.  The pin is then removed from the ampul.  The opening left upon the removal of the pin, is closed by means such as sonic welding.  The temperatures of the injection-moulding  and the blow-moulding, as well as other procedures, help to insure the sterility of the medicaments.          Alternate embodiments of the manufacturing process involve the sealing of a cap over the opening in the neck area of the ampul.          Further embodiments of the process involve the affixing of a hypodermic needle to the ampul.

Therefore, the number of entering stops causing a minimum of time losses is determined per elevator cabin on the basis of calculations.  The number of entering stops is stored in monitoring or control counters by means of which the allocation of descent storey calls is limited to the number stored for each cabin.  The descent storey calls are combined by means of a switching circuit to form groups of chronologically inputted or incoming storey calls of a volume corresponding to the number of storey calls respectively stored in the monitoring or control counter.  In the case of an increase in the storey calls, the earliest group of storey calls is first increased and the latest group of storey calls last.  The increase of numbers in the group occurs by transfer of a storey call from the next later group of storey calls and the latest storey call is allocated to the latest group of storey calls.  Thus, groups of storey calls are formed, each of which have the same size until the control counting state or level of the monitoring or control counter is reached.  The groups of storey calls are allocated to the different cabins such that the average time losses of the passengers become a minimum.
