Granted: 1985-04-10
Abstract: An apparatus is disclosed for the automatic coating of articles. The apparatus has a spray device controlled by a programmed control device. A transport device transports the articles along a predetermined path to a coating position and then away therefrom after coating. A sensor monitors the position of the article and generates signals representative thereof, preferably generating one signal each time the article moves a predetermined distance (e.g. 2 cm.) along the path. A second sensor generates additional signals to the control device when an article passes a predetermined point, also indicating which of several types of articles has been detected. The control device controls the spraying process responsive to these signals. If desired, portions of the article that are moved sequentially into the coating position can be sprayed in different manners, e.g. with the spray devices positioned or oriented differently, or using different coating materials, etc. The control device is preferably reprogrammable.

Title: Reusable electrophotographic element and process for preparing that element
IPC: G03G5/05
Filed: 1981-10-27
Granted: 1985-07-10
Abstract: A reusable electrophotographic element comprising a photoconductive layer containing sensitized zinc oxide particles and first and second binding agents that are incompatible is produced by employing as the first binding agent a macromolecular compound that has a higher affinity to zinc oxide than the second binding agent, is largely deposited on the zinc oxide, has an average molecular weight of at least 12,000 and is present in the photoconductive layer in an amount of 1.5 to 9% by weight calculated on the zinc oxide, with the second binding agent present in substantially larger amount. The photoconductive layer is formed of agglomerates of zinc oxide particles substantially enveloped in the first binding agent, which agglomerates have a diameter of between 2.5 and 6  mu m and are stuck together by portions of the second binding agent, thus providing a substantially porous photoconductive layer having a negative charge density of at most 1 m Coulomb per m2. The photoconductive layer is produced by mixing together the zinc oxide, any desired dye sensitizer, and solutions of the binding agents in one or more volatilizable solvents, applying a layer of the resulting dispersion to a substrate suited for electrophotography and drying the applied layer. The electrophotographic element has a very high resistance to both electrical and mechanical influences, thus being suited for long service life in an electrophotographic copying machine.

Abstract: A monitoring system for monitoring the condition in a vehicle wheel mounted tire. The system includes first and second LC circuits disposed within the tire and interconnected by a diode multiplier in series with a pressure switch. An exciter establishes an energetic electromagnetic field of a first frequency such that a first LC circuit is resonant at the same first frequency. This first frequency is converted into energy of a second frequency by a harmonic multiplier diode and is impressed upon a second LC circuit which is resonant at the second frequency, the second frequency being either an even or odd harmonic of the first (exciting) frequency. A receiver tuned to the second frequency interrogates the second LC circuit for presence of harmonic energy at the second frequency. A pressure switch opens when the tire pressure falls below a predetermined pressure which prevents activation of the second LC circuit so that the receiver will not sense the second frequency to which the second LC circuit is resonant, in which case there is provided an indication that the tire pressure is below the desired pressure. A scanner scans the receiver successively from one tire to another of a vehicle.

Granted: 1986-05-28
Abstract: The invention relates to a pad for launching toy vehicles whose motors have been previously energized onto a track, comprising a plate provided with an annular runway on which the vehicles are placed, and a turnstile having arms which separate the vehicles and constitute a stop for each of them. A pawl stops the turnstile from rotating. Retraction of this pawl by action on its rod permits, due to the fact that the drive wheels of each vehicle are providing torque, rotation of the turnstile which thus releases the first vehicle. The rotation of the turnstile causes return into blocking position of the pawl whose rod is then extended in a position to be actuated by a vehicle finishing its run on the track. The invention is particularly applicable to games and toys.

Title: Control system for ink jet printing element
IPC: B41J2/045
Filed: 1983-07-01
Granted: 1989-12-27
Abstract: The control system is applied to an ink jet head (9) in which the individual drops of ink are expelled from a container by way of a nozzle by the effect of contractions of a piezoelectric transducer (10) applied to the container. The transducer is included in an oscillatory circuit (22, 10) which is normally connected to a dc voltage source (20). A pulse generator (G) acts on a switch (15) to generate a voltage wave in the oscillatory circuit of the transducer and interrupts the pulse when the current in the oscillatory circuit goes to zero, whereby a single voltage wave with a low harmonics content is generated. The oscillatory circuit is so designed that the frequency spectrum created by the voltage wave drops rapidly with frequencies higher than the reso. nance frequency of the oscillatory circuit and has at least one node close to the resonance frequency at the lowest nodal diameter mode of vibration of the meniscus.

Abstract: An apparatus for fitting receptacles at a predetermined spacing with respective substantially identical objects each having a bottom face has a plate generally centered on an upright plate axis and having a substantially planar, smooth, and horizontal upper face with a generally circular outer edge. A feeder deposits the objects on the upper face of the plate radially inward of the edge thereof such that these objects sit on this upper plate face by their bottom faces. A plurality of individual seats distributed at the spacing of the receptacles along the outer edge of the upper face of the plate each have a floor coplanar with the upper plate face and a shape complementary with that of one of the objects. A guide member has an inner edge above the upper face of the plate immediately adjacent same, and a plurality of respective passages which each open at one end at this inner edge and at the other end at the respective seat. Each such passage is so dimensioned that the objects can pass one by one from the respective inner edge to the respective seat. A drive rotates the plate relative to a fixed support in a predetermined direction about the plate axis. A radially outwardly directed force is exerted on the objects by rotating the plate at high speed to urge them toward the outer edge of the face and toward the seats via the passages of the guide member.

Title: Sea anchor for changeable drag
IPC: B63B21/48
Filed: 1983-11-23
Granted: 1991-07-31
Abstract: A sea anchor designed to even-out fluctuations in vessel speed when running before a sea. When nose (11), which is attached by cable (37) to the vessel, experiences a pull greater than a predetermined magnitude, spring (23) is compressed (as shown), plates (33) pivot, and ports (32) are opened. This opening changes the sea anchor from its former streamlined shape to one of greater drag due to increase in the projected surface area and in the turbulence produced. Stability against spin is provided by longitudinal flow-through water passages (26) and vanes (41). The device may alternatively be used, when aligned vertically, as a buoy trailed behind a life raft. In this mode the nose is lowermost, vanes (41) serve as radar reflectors, the normally collapsed bladder (30) is inflated and a radio transmitter inside tube (18) transmits a distress signal.
