PURPOSE:To improve operational reliability by distributing feed flow rate into each of feed systems, based on a feed system with the maximum feed flow rate. CONSTITUTION:The flow rate of each of feed systems 22a-22c is separately determined by the opening and the before-and-after differential pressure of water level control valves 24a-24c. The before-and-after differential pressure of the water le...

To remove the thread waste (11) on a yarn carrier (7), the latter is clamped in a loading station (A) of the device between a take-up cone (6) and a pressing cone (8) arranged on a carriage (3) which slides to and fro on a carriage guide (1). During this movement, the yarn carrier (7) first passes through a cutting station (B) in which the thread waste (11) on the yarn carrier (7) is cut by blades...

Shrimp are conveyed in upright orientation upon a pair of spaced rails that revolve in upright planes and which strike bumpers. The shirmp may be size sorted by orienting the rails such that their spacing changes. The shirmp are deheaded by conveying then to a deheader that has a pinch finger that swings by a pinch block and clamp.

A nozzle assembly is provided for a container and dispenser which maintains a supply of liquid, such as saline solution for contact lenses, in sterile condition during storage and has a flexible wall for manually squeezed displacement of the dispensed liquid from a storage cavity within the container. The nozzle assembly includes first and second conduits for defining separate fluid flow paths bet...

A disconnectable electrical plug for use with a urological endoscope comprising a housing; a conductor; a connector; and an extension block keyed for insertion into a guide block of the endoscope. The extension block extends from the housing at a substantially right angle to the entry of the condutor into the housing and is insertable into the guide block in either a first or second position. A ur...

The present invention is directed to a tire comprising a three-dimensional wound reinforcement formed from a continuous sheathed filament running diagonally over the region upon which the tread is located and alternating from one tire foot to the other, said filament (i) crossing back and forth over said region, (ii) running into the tire foot tangentially, (iii) running for a relatively long dist...

A process by which polyester resin having extremely high molecular weight can be prepared utilizing a very rapid solid state polymerization process comprises: (1) dissolving a polyester prepolymer in a suitable organic solvent; (2) recovering the polyester prepolymer from the organic solvent to produce a porous, fibrous mass of the polyester prepolymer; and (3) solid state polymerizing the porous,...

A polyester resin is disclosed which is resistant to splitting during transverse orientation during conventional film manufacturing. The polyester resin contains up to 7 weight percent, based uon the total weight of the resin, of (A) a dicarboxylic acid component consisting essentially of 1,4-cyclohexandeicarboxylic acid having a trans isomer content of at least 70% (B) a glycol component consisti...

In a method for the detection of blemishes on the surface of an object, e.g. for the detection of blemishes in the paintwork on the surface of a motor vehicle body, a strip of light is produced on the surface by means of a lighting system, and this strip of light is moved over the surface by relative movement between the lighting system and the surface; strip-like sections of the surface of the ob...

An industrial truck comprising at least one steerable wheel is to be guided in dependence on direction-controlling signals which are transmitted to the industrial truck. At a junction the truck receives a direction-controlling steering signal, which causes the at least one steerable wheel to be laterally offset from the guiding signal line until a signal equilibrium which depends on the offset has...

A non-contact row crop sensor comprises one or more transmitter/receptor pairs mounted on two row separators of a harvesting machine. Each transmitter transmits an energy beam to one of the receptors and the energy beams cross at a point which defines a position of the harvesting machine relative to a row of crop stalks. A circuit produces steering control signals dependent upon the time of interc...

A navigation system for use in a self guided material handling vehicle provides guidance during operation in areas having densely stacked rows of containers and reduces the potential of deviation of the self guided vehicle from the desired path of travel. A laser signaling device is mounted on the vehicle and rotatable about an axis of rotation extending generally perpendicularly to the longitudin...

An automatically-guided, driverless vehicle for handling loads has a selectively openable and closeable load clamp. The clamp is equipped with various sensors for automatically sensing the load and other objects and surfaces surrounding the load, and controlling the movement of the clamp along a loadengaging direction, the vertical reciprocation of the clamp, and the opening and the closing of the...

Oriented polyester film primer coated with a hydrolyzed aminosilane IS disclosed. The aminosilanes in the unhydrolyzed state have the formula: (R<1>)aSi(R<2>)b(R<3>)c wherein R<1> is a functional group with at least one primary amino group; R<2> is a hydrolyzeable group such as a lower alkoxy group, an acetoxy group, or a halide; and R<3> is a nonreactive, nonhydrolyzeable group such as a lower a...

A brake arrangement is disclosed which includes a wheel support, a wheel borne by the wheel support, a brake drum, at least one brake guide saddle arranged in the brake drum so as to bear against the wheel support, a fluid drive piston arranged in a bore in the guide saddle, the guide saddle having guide lugs extending in a direction parallel to the direction of the bore, the guide lugs delimiting...

A composite, microscopically transparent, porous membrane is formed from a porous polytetrafluoroethylene membrane having desired bulk properties on which is directly coated a cross-linked polymer having desired surface properties. The composite membrane retains the porosity of the porous polymeric membrane.

Plastic foam materials having a high degree of structural integrity, cell network uniformity and small cell size are obtained from (meth)acrylic acid and (meth)acrylonitrile by incorporating acrylamide as a comonomer additive within certain ranges of concentration. Incorporation of the latter together with conventional additives normally used in preparing foams from the principal monomers helps to...
