Title: Bicycle helmet adjustment mechanism
Filed: 2010-03-17
Abstract: A helmet adjustment mechanism is adapted to adjust the size of a helmet having first and second retention members (e.g., plastic straps) movable with respect to each other. The adjustment mechanism includes an actuating member (e.g., a pinion) coupled to at least one of the retention members and movable (e.g., rotatable) in two directions to move at least one of the retention members relative to the other. A clutch mechanism is coupled to the actuating member and includes at least one locking member (e.g., two locking members) that inhibits movement of the actuating member in both of the two directions. The adjustment mechanism also includes a release mechanism (e.g., including a rotary dial) adapted to move the locking member from a locked position to an unlocked position to allow movement of the actuating member. When the actuating member is being moved, the adjustment mechanism also provides a ratcheting detent.

Title: Process for producing concentrated sulfuric acid
Inventor: DORR KARL-HEINZ DIPL ING
IPC: C01B17/775
Filed: 1980-10-10
Granted: 1982-09-16
Abstract: SO2-containing, hot gases are catalytically converted in part in a first contacting stage. The water and the SO3 formed is removed from the reaction gas. The remaining gas is heated and then supplied to the second contacting stage. The water vapor content in the reaction gas delivered by a first contacting stage corresponds to an H2O/SO3 mole ratio below 1. The reaction gas delivered by the first contacting stage is precooled by an indirect heat exchange to such a temperature that the wall temperatures of the heat exchanger are above the dew point temperature of the reaction gas. The precooled reaction gas entering a condensing stage is contacted in a venturi with cocurrent sulfuric acid of 98.0 to 100% concentration and a temperature of at least 95 DEG  C. The exit temperature of the gas from the condensing stage is maintained at least at 120 DEG  C. The gas rises in a succeeding absorption stage through a packing layer, which is contacted with trickling sulfuric acid having a concentration of 98 to 100% and a temperature of 70 DEG  to 120 DEG C. The dry gas which leaves the absorption stage and has been freed from SO3 is maintained at a temperature which is as high as or slightly higher than the temperature of the acid as it initially contacts the packing in the absorption stage. The sulfuric acid concentration is controlled by a supply of water into the sulfuric acid in the condensing and/or absorption stage.

Title: Spectrum converter for analog signals
Inventor: DE NIET EDMOND
IPC: H04L25/49
Filed: 1980-04-23
Granted: 1983-03-17
Abstract: A device for receiving analog and discrete input signals and for converting the spectrum thereof without loss of information. The resultant signal has a frequency response curve which exhibits zero points at the frequency zero and at half the sample frequency. The second zero point is then suitable for addition of a pilot tone, without the required bandwidth being increased and without interference with the data signal. The device comprises two integrating feedback loops (32, 24/40), the output signals of which are alternately activated. The sign of the active output signal determines the sign of the input signal of the feedback loops and of the output signal of the device. One feedback loop directly receives said output signal, while the other feedback loop receives this output signal via a multiplier which alternately receives a positive and a negative multiplicand.

Granted: 1985-10-03
Abstract: Improvement in the impregnation process of wood and other materials, with resins. It is already well known that some processes have the purpose of improving the features and the possibilities of use of some materials, based upon impregnation thereof with resins. Said processes generally consist in the introduction of liquid organic monomers into the materials to be treated and the successive polymerization thereof in loco, as to realize a composite material of a better quality. The different stages of said process, i.e.: the degasing of the air, the impregnation by means of the monomers and the successive thermocatalytic polymerization take place in a single, thermically adjustable container, without the need of transferring the material into different devices, reducing the duration of the treatment and making use of a plant which is much simplier in the use.

Title: Tilting vessel for the treatment of cast iron melts
Inventor: BISSCHOP HUBERTUS A J M
IPC: C21C1/10
Filed: 1982-01-26
Granted: 1985-09-26
Abstract: A method of and a ladle for the treatment of a cast iron melt with a substance capable of inducing the formation of spheroidal graphite utilizes an elongated generally cylindrical vessel lined with a refractory and formed at opposite ends with cylinder bottoms. The vessel can be tilted between a horizontal and upright orientation and angularly displaced about a longitudinal axis at least in its horizontal orientation. A partition in the vessel adjacent one of the cylinder bottoms defines a chamber at one end of the vessel opening within the vessel toward the opposite end thereof and disposed at an upper portion of the vessel in its horizontal orientation. A closable opening at the other end of the vessel enables a cast iron charge to be introduced into the vessel in the horizontal orientation thereof. The vessel is then tilted upwardly to effect the reaction and swung back to its horizontal orientation for deslagging before the charge is tapped by angular displacement about the longitudinal axis.

Title: Product and process for deacidification in various liquids and, more particularly, the elimination of malic acid of musts and wines
Inventor: GEOLIER EPOUSE VIALATTE C S E
IPC: C12H1/10
Filed: 1982-03-09
Granted: 1985-10-31
Abstract: Food liquids such as wines are deacidified by removing malic acid without substantially affecting the tartaric acid content of the liquids. Deacidification is carried out by adding to the liquid calcium carbonate, potassium bicarbonate, calcium tartrate and a calcium double salt of tartaric and malic acids to cause precipitation of crystals of tartromalate from the liquid. The amount of calcium carbonate is sufficient to increase the pH of the food liquid to 4.5. The amount of calcium tartrate is sufficient to eliminate the portion of malic acid beyond the tartaric acid stoichiometrically equivalent content.

Granted: 1986-04-17
Abstract: A method of determining the electrostatic charge on the surface (2) of an electrically insulating sheet material (3) - e.g. an electrophotographic film - is disclosed. The method uses the fact that an electrode placed against the opposite surface of a charged material will tend to have an opposite charge through induction. Thus an electrode (4) which may be part of the structure of an electrophotographic material is connected to earth through an electrical circuit (6). Two suitable circuits are described, one using the principle of a virtual earth amplifier and the other using a circuit arrangement which gives a measurable voltage which corresponds to the integral with respect to time of the current flowing through the lead (8) from the circuit (6) to the electrode (4).
