Apparatus for adding measured quantities of concentrates or solutions, e.g., particularly fluoride salt solutions, to a second liquid, e.g., fresh water as supplied by municipalities to ordinary residences. The apparatus is particularly adapted to be fitted into a conduit carrying a supply of fresh water to a source to be supplied with fluorinated water, e.g., a residence. It is constituted generally of an outer vessel within which a tubular flow nozzle is enclosed. The nozzle is provided with h...

The intake orifice of a screw type valve is connected to a liquid reservoir. Mounted at the output orifice of the screw valve by detachable spring clips is a ball valve. The rate of liquid flow through the screw valve can be preset by adjustment of the handle of the screw valve. The ball valve may be actuated from an off to an on position for a preset period of time by an electrically actuated solenoid and linkage. The total volume of liquid flowing through the apparatus for each actuation of th...

An improved predetermined speed detector for use in a digital tachometer where signal pulses proportional in repetition rate to engine speed or RPM are available. The signal pulses are used to trigger a monostable multivibrator such that the duty cycle of the monostable output is a function of the signal pulse repetition rate (hence RPM) and the characteristic period of the monostable circuit. The time coincidence of the input signal pulses and the monostable output is then detected to obtain an...

A wire harness includes a circuit unit having a plurality of electric wires with a predetermined path, a first soft sheet material formed into the shape as that of the predetermined path and a second soft sheet material adhesively joined to the first soft sheet material so that the circuit unit is interposed between the first and the second soft sheet materials.

A circuit which includes an operational amplifier generates an output current which is related to an input current raised to a predetermined power. A first diode is connected between one operational amplifier input terminal and ground and the input current injected therethrough. A second diode is resistively coupled between the second operational amplifier input terminal and ground while another resistor connects that input terminal to the operational amplifier output terminal. A further diode m...

Apparatus for discharging predetermined quantities of food for dairy cows and beef cattle, which apparatus comprises a hopper, an elongate flat-sided housing, a conveyor positioned in a conveyor section of the housing, a plurality of separate collector compartments formed in a collector section of the housing, and a plurality of sliding plates joined to a common rod for simultaneously closing and opening a plurality of discharge apertures in the collector compartments.

A metal film having a predetermined thickness profile is obtained on a surface of an article through electroplating. The electroplating of the metal film on the article is done with an apparatus including a plurality of modifying electrodes and a body of plating material suspended in a plating solution. Electrical potentials are established at the article to be plated, the body of plating material, and at each one of the modifying electrodes. The particular electrical potential at the article, t...

In the hitherto known apparatus of a similar kind the table adapted to support thereon a shape being cut out is mounted on a base for motion solely in a vertical direction. A characteristic feature of an apparatus in accordance with the invention is that the table for accommodation thereon of the shape being cut out is mounted on a base for longitudinal motion relative to the parallel sides of a template equidistant from the contour of the shape being cut out, in opposite directions, the drive o...

The device for cutting a web into sections according to cutting marks provided on the web comprises an advancing roller for advancing the web along a predetermined track, an electrooptical scanning device for reading respective cutting marks on the web and for generating corresponding output signals, a cutting mechanism arranged on the track behind the advancing roller and monitored by the scanning, a tension equalizing and loop forming device arranged on the track before the advancing roller an...

The high speed rotary cutters of a machine for automatically severing whole poultry bodies into separate portions are provided with nozzles which direct jets of cold water against the major areas of both surfaces of the cutters to increase their efficiency, and an enclosure which confines the water thrown off from the cutters is provided with a grid which prevents the severed portions from coming into contact with the water being removed from the enclosure.
