Granted: 1992-10-13
Abstract: Hydraulic Diaphragm Pump Method and Apparatus Abstract A hydraulically activated diaphragm pump.  A pressure source is coupled to a pump diaphragm during a pump discharge stroke.  During this discharge stroke, an air activated return assist cylinder is vented to atmosphere. On the return stroke the pump housing above the diaphragm is vented and the air cylinder activated.  A single 4-way solenoid actuated valve controlled by an adjustable timer accomplishes this cylic pumping action.  The timer is adjustable to set the number of pump cycles per minute and also adjusts the discharge stroke period of each cycle.

Abstract: PROCESS OF FILLING A CONTAINER, DEVICE FOR THIS PURPOSE  AND METHOD FOR ITS OPERATION                         A B S T R A C T                   In order to fill a container having a check valve with a spontaneously foaming filling material, the latter is introduced through the check valve already mounted at the container.  In a piston arrangement as the filling device, filling material to be filled in is sucked into a mixing chamber (65) by means of a metering piston (60), foam gas is injected through the piston rod (58) of this piston, filling material and gas are mixed by means of a mixing piston (56), then forced by means of the metering piston (60) through the check valve into the container.  This prevents frothing of the filling material, intermixed with foam gas, at any point in time between mixing and filling.  During mixing, slight foaming is desirable in order to increase the absorption capacity for the foam gas.         (Figure 7)

Abstract: ABSTRACT OF THE DISCLOSURE         Azetidin-2-ones that are N-substituted by a phenyl group carrying a selected ortho- or para-substituent are subjected to electrochemical oxidation to yield N-unsubstituted azetidin-2-ones.  The N-substituted azetidin-2-ones can bear other substituents, provided that the substituents are such that the reaction proceeds without undesired substantial oxidation of the remainder of the molecule.  The oxidation can be carried out in a liquid medium that comprises up to about 50% water and a substantially inert organic solvent, using platinum or platinised titanium as working electrode.  Suitably the temperature is in the range of about -5°C to about +85°C, the potential of the working electrode is in the range 1.2 to 1.8 relative to a reference electrode and the pH is maintained in the range 4 to 7.  The obtained N-unsubstituted azetidin-2-ones are useful as inter-mediates in the preparation of .beta.-lactam antibiotics.

Abstract: ABSTRACT     An electronic calendaring method for use in a data processing system which includes a plurality of interactive terminals which are interconnected to permit an end user at each terminal to interchange information with each other and to maintain an electronic calendar. The method facilitates the reply process to an electronic invitation to attend a meeting that is issued by one of the end users by arranging for the system to advise the invitee that a meeting notice is available for review in the "In Box" of the terminal. The method causes a composite screen to be built which simultaneously displays the meeting details and the relevant section, i.e. a day of entries, of the owner's calendar in a side by side format so that  calendar entries are correlated to the meeting date and time. The composite display permits an interactive selection by the calendar owner end user of at least one option which can be either to accept the invitation and calendar the meeting or to reject the invitation. In either event a reply is automatically sent to the end user that issued the invitation and the invitee is returned to the task that was being processed when the initial message was received.

Abstract: In order to take a practically unlimited number of fluid samples, in particular from a well in production, a sonde is used including as many modular sampling devices (10) as there are samples to be taken.  These devices (10) are disposed end-to-end and they are actuated in succession by a central control rod (66) driven back-and-forth by an actuator device situated at the top end of the sonde.  A bottom end piece puts the bottom sampling device into a ready position in which it is ready to be actuated by raising the rod (66).  By taking a sample in this way, the bottom sampling device also serves to put the adjacent sampling device into its ready position, and so on all the way up to the topmost sampling device.

Abstract: A piezoelectric buzzer comprising a case having the shape of a bottomed cylinder, a piezoelectric diaphragm fixedly disposed within the case, a cover plate fitted in the open end of the case, and terminals integrally combined with the cover plate and each having one end in contact with the piezoelectric diaphragm and the other end projecting outside from the cover plate.  Since the cover plate and the terminals are combined together by insert molding, no gap is formed between the cover plate and the terminals, no sealing work for sealing gaps between the cover plate and the terminals is necessary, the manufacturing process is simplified, and the piezoelectric element is not exposed to the external atmosphere.  A method of manufacturing such a piezoelectric buzzer comprises steps of arranging a plurality of metallic strips for forming terminals in parallel to each other, forming notches in one side of each metallic strip at predetermined intervals, simultaneously forming a plurality of cover plates integrally combined with the metallic strips by insert molding, cutting the metallic strips at predetermined positions between the adjacent cover plates, and bending the metallic strips projecting from each cover plate at the notches to form terminals.  The metallic strips can be easily bent at the notches to form the terminals after being combined with the cover plates by insert molding  without requiring special work for deciding positions where the metallic strips are to be bent.
