In a deep fat fryer having a tank for cooking oil containing an electrical heating grid, a safety thermostat switch mechanically connected with the grid by a metallic, thermal cut out clip. The clip is tightly clamped to the grid and to the housing of the thermostat switch to assure rapid heat transfer from the grid to the thermostat. The thermostat switch is connected in an electrical circuit to interrupt flow to the grid in the event that the cooking oil in the heating tank is overheated, or t...

The present invention provides compounds of the general formula I and physiologically acceptable addition salts thereof: in which R.sup.1 represents a hydrogen atom or a lower alkyl group; R.sup.2 represents a hydrogen atom or a benzyl or benzhydryl group; R.sup.3 represents a hydrogen atom or a lower alkyl group or R.sup.3 represents an arylalkyl or aryloxyalkyl radical, which radicals may optionally be substituted by one or more alkoxy or hydroxyl groups; Z represents a group of formula --(CH....

The container for a product to be dispensed by a pressurized fluid includes a diaphragm of baglike configuration preferably formed of ductile metal and having a rigid base. A hollow, ring or cup slidably mounted within the diaphragm and container has a rounded end wall over which the diaphragm slides as the product is being dispensed.

A slide member mountable in a horizontal, slotted track or traverse rod, has an arm carrying a U-shaped hook member. One part of a snap fastener is secured to one leg of the hook member and the other part is adapted to be secured to a drape or curtain.

A U-tube is connected to a pressure vessel, the vessel and the U-tube containing an operating liquid, and the vessel also being connected to conduit means leading from a source of gas pressure. A bubbler tube is disposed in a container holding the controlling liquid, and is connected to the conduit means. The U-tube includes a sight glass portion having disposed therein a float containing magnetic means, which float rises and falls in response to the level of the controlling liquid in the contai...

A chemical service unit removably connected or incorporated in portable lavatory accommodation comprises a chemical liquid container divided by a filter screen into a first compartment containing clear liquid and a second compartment receiving discharge from the accommodation. A continuously operable pump draws off flushing liquid from the second compartment and delivers it to cisterns; a by pass connection including a pressure relief valve passes liquid to the first compartment and creates the ...

A rectangular gate is mounted to pivot, in a vertical plane, about an axis at a lower corner of the gate, a first spring urges the gate toward open position and a second spring acts, as the gate approaches open position, to resist the action of the first spring. The pivot for the gate is a horizontal, selectively power driven, shaft and the gate is mounted on the shaft by a split-band adjustable friction clutch so that the gate may be opened or closed manually or by power means, selectively.

A system for feeding a grinder having at least one pocket for receiving logs to be grounded. The system comprises a magazine located above the grinder pocket for storing logs to be fed into the grinder pocket, a conveyor system located above the grinder for feeding logs to the grinder, and a gate located in the conveyor system right above the magazine for discharging logs into the magazine. The magazine includes a plurality of loading boxes located one above the other and each including a gate f...

A pivoted knee joint for an orthopedic leg brace provides for both pivoting and relative sliding movement. When the user's weight is placed on the braced leg and the leg is substantially straight, the joint is locked against pivoting but is freely pivotable when the leg is lifted. If the weight of the user is placed on the leg while the leg is partially bent at the knee, the joint locks against pivoting to prevent collapse of the user.

A plurality of coin wrapping machines are arranged so that each delivers sequential rolls of coins to a tiltable cradle associated therewith and which is caused to tilt at a controlled time to drop the roll onto a common conveyor apparatus having a fixed surface, the rolls are dropped immediately behind pushers on roller chains rollable on the surface. Spaced pushers on the chains are far enough apart to accommodate a roll from each machine so that each roll drops directly onto the surface even ...
