There is provided a programmable controller comprising a standard microprocessor having output address terminals and input/output bi-directional data terminals and means for providing a binary code on the data terminals indicative of the status of the machine cycle to be processed by the microprocessor. This programmable controller includes a logic decoder means for producing a selected signal in response to logic signals on selected address terminals and in the status binary code of the data te...

Cheese is prepared by ultrafiltering a milk product to produce a cheese milk having substantially the composition of cheese at the end of whey drainage and converting the cheese milk into cheese by coagulation with rennet.

A multiplier using Hall element comprises a Hall element with a pair of control current input terminals and a pair of Hall output terminals, an electromagnet for converting load current into magnetic field and for applying the magnetic field to the Hall element, a transformer for converting load voltage into control current, and a constant current circuit for making the secondary current of the transformer constant and then feeding it to said control current input terminals. The Hall element pro...

A novel article for accommodating a heat sealable laminar assembly while heat is applied thereto.

A device which is used in the vagina to deliver spermicidal surfactants. This device can be inserted by the user, and does not require insertion by a physician as, for example, in the case of intrauterine contraceptive devices. By virtue of its unique construction and shape, the device herein is foldable for easy insertion. Once in position at the cervical os, the device opens to "cap" the os and remain in position, even during intercourse, so that access of the spermicidal surfactant source to ...

The container of the present invention includes polygonal sidewalls with at least some of the upper edges of the side walls each having a container locking flap thereon and with at least one other of the side walls being free from locking flaps. The lid has polygonal edge walls sized to matingly fit over the upper edges of the container side walls. Each of the edge walls of the lid are provided with a lid lock flap which folds upwardly and inwardly with respect to the edge walls and which termin...

An industrial dryer particularly suited for small parts has a tub to contain the parts and a helical ramp along the interior tub wall. Vibratory motion makes the small parts move along the ramp. The tub has a double wall, the inside space between the walls defining an air plenum. The interior wall of the tub is formed with exit spaces through which the hot air emerges and blows over the parts as they move along the ramp. The plenum is continuously supplied with hot air to replace the losses. A u...

A dielectric resonator is housed within an internal space of a metallic casing. An amplifier is disposed outside the space and an input and output circuits are connected to the amplifier. An output coupling window is formed in the casing at the position corresponding to the output circuit of the amplifier and an input coupling window is formed in the casing at the position corresponding to the input circuit of the amplifier. An electromagnetic wave leaking from the output circuit of the amplifie...

.alpha.-substituted derivatives of valproic acid are provided for conjugation to antigenic compositions, particularly poly(amino acids), and enzymes. The antigenic conjugates are employed for the production of antibodies, which find particular use in immunoassays for the determination of valproate, while the enzyme conjugate finds use in a homogeneous enzyme immunoassay for the determination of valproate. The compounds are synthesized by alkylating valproate at the tertiary carbon atom by an ali...

A warning apparatus comprises a Gunn oscillator, a transmitting antenna, a receiving antenna, a detector, and a comparator which produces a detecting signal when the output signal from the detector is belowed a reference level. The warning apparatus further comprises a drive circuit for applying a rectangular pulse voltage to the Gunn oscillator, a band-pass filter allowing only a microwave with the transmitting frequency band of microwaves received by the receiving antenna to pass therethrough,...
