  • Patent number: 4897957
    Abstract: The precision flowering of Regal Pelargoniums includes the following six stages: the production of pathogen indexed Mother Block and selection phase, the stock plant production phase, the vegetative propagation post-harvest phases. By means of temperature control and misting during vegetative propagation, careful control of temperature and accumulated light during floral initiation, and night-break lighting during finishing if necessary, flowering Regal Pelargoniums may be produced any time during the year. Moreover, as a result of the combined method steps of the present application, the production of a finished, flowering plant from a stock plant cutting may be completed in a total of 13 to 16 weeks.

  • Patent number: 4852738
    Abstract: A disposable dental tray includes a disposable tray body defining four utility compartments. Three of the utility compartments are disposed along a first side of the tray body, the fourth utility compartment being disposed along a second side of the tray body. All four of the utility compartments have relatively flat bases and are defined by integrally formed ridges extending upwardly from the compartment bases. Each compartment is surrounded by a defining ridge, interior defining ridges being offset from each other so that no interior ridge extends completely across the tray. The tray body further includes an instrument compartment defined by an encircling ridge extending upwardly from the base of the instrument compartment. The instrument compartment has integrally formed therein a series of grooves for holding dental instruments, which grooves are elevated above the base of the instrument compartment.

  • Patent number: 4119642
    Abstract: Compounds containing the butenolide ring have a wide variety of chemical uses. The invention is an improved method of synthesizing .beta.-halobutenolides which are valuable intermediates in preparing a variety of butenolide ring containing compounds. The method comprises reacting an acetylenic alcohol with a mercuric halide to provide a vinylmercuric halide and carbonylating the vinylmercuric halide in the presence of a basic inorganic salt to provide a .beta.-halobutenolide.

  • Patent number: 4093986
    Abstract: Storage protection is provided in a computer system having address translation by loading address translate registers with valid translated addresses and with special addresses. A circuit for generating a storage exception signal is connected to receive all addresses from the translate registers which are addressed by the main storage address and generates a storage exception signal in response to detecting a special address. The address translation mode is provided for both a main storage processor and a control processor with a separate address translate control register for each processor. Address translation is automatically selected based upon interrupt level. Address translation registers are also provided for I/O operations and are controlled independently from and can be in parallel with the task address translation registers.

  • Patent number: 4077060
    Abstract: An asymmetrical multiprocessor system has a main storage or macroprocessor connected under control of a microprocessor for initiation and termination of operation of the macroprocessor. The macroprocessor after being started by the microprocessor runs until a check condition in the macroprocessor occurs, a non-executable operation code (OP code) in the macroprocessor is encountered, or the microprocessor wants control. When the macroprocessor stops the microprocessor is interrupted. The interrupt routine handles the condition causing the interrupt and restarts the macroprocessor. Non-executable OP codes include supervisor call and invalid OP codes. I/O operations are handled by the supervisor call instruction.

  • Patent number: 4052423
    Abstract: .alpha.,.beta.-Unsaturated carboxylic acids and esters have a wide variety of chemical uses. The invention is a method of synthesizing .alpha.,.beta.-unsaturated carboxylic acids and esters which, with regard to the esters, comprises reacting a vinylmercuric halide with carbon monoxide in an alcohol to provide an .alpha.,.beta.-unsaturated carboxylic acid ester. With regard to the acids per se, the method comprises reacting a vinylmercuric halide with carbon monoxide, in the presence of a water containing polar organic solvent to provide an .alpha.,.beta.-unsaturated carboxylic acid.
