Title: Modular switch device
Inventor: DUNCAN WILLIAM M
IPC: G01L9/00
Filed: 1988-09-16
Abstract: A modular switch device (20) includes a housing (22) enclosing an interconnected control module (70), a display mo­
dule (72) and a power module (74). A sensor module (42) supplying analog data signals from one of a temperature (104) or 
pressure sensing element (170) connects to the control module (70) through a passage (48) in the housing. A user can select 
between AC and DC switched output modules (66) and the presence or absence of a 4-20 milliampere output module (62, 
64) by plugging and unplugging same from wells (56, 58, 60) provided in the housing. The manufacturer and user thus can 
modify the standard housing, which includes an internal electrical assembly to be a pressure or temperature switch and to 
provide selected output switch characteristics by applying and removing selected sensor and output modules thereto. The 
control module (70) includes one analog to digital converter (134) and controls via microprocessor (136). The sensor mo­
dule (42) includes an amplifier (120), a reference voltage circuit (122) and a non-volatile memory (124) containing calibra­
tion data.

Abstract: DNA strand having an ability in biotechnological production of α-acetolactate decarboxylase is disclosed. The DNA strand is characterized in that it has a nucleotide sequence coding for a polypeptide whose amino acid sequence is substantially from A to B of Fig. 1 and which has α-acetolactate decarboxcylase activity. Also disclosed is a yeast which belongs to Saccharomyces cerevisiae and which has been transformed by the DNA strand. The yeast is characterized by the fact that its α-acetolactate producing ability is reduced, and will thus produce an alcoholic liquor such as beer which contains no or little diacetyls which have come from their precursor, namely α-acetolactate.

The liquid passage is opened when the long engaging elements (38) of the operating button (23) make contact with the protrusions (45) of the rotatable slider (31). In this case, the operating button (23) protrudes upward above the upper lid (24) of the liquid container. In contrast, the liquid passage is closed when the short engaging elements (39) of the operating button (23) make contact with the protrusions (45) of the rotatable slider (31), and in this case, the operating button (23) is hidden below the upper lid (24). Thus, the valve open state is more easily checked visually.

Abstract: Stable, clear, antimicrobially effective, ophthalmic formulations are disclosed which provide an antimicrobially effective preservative. The formulations include an ophthalmologically effective amount of a drug, which is a -COOH group-containing non-steroidal anti-inflammatory drug (NSAID) in combination with an antibiotic drug, and a preservative system formed of a quaternary ammonium preservative and a nonionic polyoxyethylated octylphenol surfactant, all in an aqueous vehicle. The preservative system can be used with other formulations which require the preservative to be ophthamologically acceptable and antimicrobially effective. These formulations are useful for treating diseases and/or conditions that are either caused by, associated with or accompanied by inflammatory processes, including, among others, glaucoma, cystoid macular edema, uveitis, diabetic retinopathy and conjunctivitis, or any trauma caused by eye surgery or eye injury. The ophthalmologically acceptable antibiotic is preferably tobramycin which has been found not to interfere with the rate of diffusion of the NSAID. The combination of the NSAID and antibiotic is particularly effective in simultaneously preventing and/or eliminating infection while preventing and/or eliminating inflammation.
