Title: High-speed coin sorting and counting apparatus
Inventor: CHILDERS ROGER K
IPC: G07D3/16
Filed: 1984-12-11
Granted: 1990-12-27
Abstract: IMPROVEMENTS IN HIGH-SPEED COIN SORTING AND COUNTING APPARATUS                          Abstract A coin-sorting and counting apparatus in which a mixture of coins of different denominations is deposited on a rotating surface and queued thereon by multiple coin guides. These coin guides define a coin-queueing channel for lining up coins on the rotating surface in an orderly fashion preparatory to introducing them into a coin-sorting channel.  To increase the speed of sorting, a coin recirculation channel is also provided for receiving certain ones of the coins which have been moved by the rotating surface past the entrance to the coin-queueing channel and redirecting such coins to such entrance.  One of the queueing channel guides also acts as a coin position retainer for retaining those coins which have been moved past the entrance of the queueing channel, without forming into the queue, at the same radial distance from the axis of the rotating surface while the surface moves such coins toward the recirculation channel.

Patent CA-1297403-C (CA)
Inventor: SCHAEFER HORST
IPC: A01N59/00
Filed: 1986-09-08
Granted: 1992-03-17
Abstract: The specification discloses a method of caring for a contact lens and a neutralizing agent for use in a contact lens care set.  The set is disclosed as having a container for receiving the neutralizing agent, the lens, and a liquid comprising hydrogen peroxide. The neutralizing agent comprises decomposing means for decomposing at least residual hydrogen peroxide on the lens into oxygen and water after the hydrogen peroxide has so sterilized the lens; and retarding agent means for delaying the time at least the decomposing means decomposes the residual hydrogen peroxide after the neutralizing agent is received in the container until after the hydrogen peroxide has so sterilized the lens. The invention provides a contact lens care set which, in one step, keeps hydrogen peroxide active sufficiently long at least for substantially sterilizing the lens and then neutralizes at least residual hydrogen peroxide on the lens at least substantially so that the lens can then be worn, at least generally, without discomfort.

Title: Backflushed air filters
Inventor: HOWETH D FRANKLIN
IPC: B01D46/52
Filed: 1986-09-29
Granted: 1992-09-01
Abstract: ABSTRACT OF THE DISCLOSURE Disclosed are pleated paper barrier type air filter elements having planar filter panels that are cleaned by a reverse air jet cleaning system which includes one or more specifically shaped cleaning air manifolds or heads in which a plurality of jet nozzles or orifices are arranged in a predetermined pattern to provide a totally enveloping air jet which is discharged into a flow tube immediately downstream of the clean air flow chamber of a generally tubular filter element. The jet pattern provides a temporary pressure seal within the flow tube and entrains a substantial amount of ambient air into the reverse flow jet to thoroughly flush elements to clean dust cake from the exterior surfaces thereof. The multiple jet arrangement reduces the overall space occupied by the reverse jet cleaning system and provides a larger mass flow of cleaning air. Multiple jet orifice heads or manifolds may be configured in virtually any geometric shape to provide a desired jet pattern. The planar filter panel elements allow high media face velocities with low flow tube velocities. Oval filters are provided which have a greater clean air flow area than a plurality of cylindrical elements fitted within the same dimensional envelope.

Title: Ink transfer arrangement
Inventor: TOBIAS PHILIP E
IPC: B41F31/06
Filed: 1987-01-30
Granted: 1991-01-15
Abstract: Ink Transfer Arrangement Abstract of the Disclosure The present device comprises a plurality of doctor blades, each of which, in a preferred embodiment, has a width of a key zone.  Each of the blades is disposed to be moved between the fountain roller of a printing press and the receiver roller of a roller train in the printing press.     Each doctor blade is held by some force such as a solenoid in a first position whereat it scrapes away ink from the fountain roller for a predetermined time, so that the amount of ink lifted from the fountain roller is predictable while at the same time the system provides for changing the predetermined time to enable the amount of ink removed from ? the fountain roller to be varied.  Each of the doctor blades is returned to a second position when the force is terminated, whereat each of the doctor blades comes in contact with a receiver roller which acts to wipe the ink from the respective doctor blades thus completing the transfer of ink from the fountain roller to the receiver roller of the roller train of a printing press.  The amount of time that each blade is located in the first position is selectively controlled by a microprocessor in the preferred embodiment.

Title: Surface cleaning appliance
Inventor: ZOELL DIETER

Granted: 1991-01-08
Abstract: SURFACE CLEANING APPLIANCE                          ABSTRACT     The appliance is intended to remove dust from solid objects and comprises an ionization device (7) which is operatively associated with an incorporated air nozzle (1), which has an obliquely arranged, narrow, linear blowing slot (2) which serves to produce an air jet which sweeps over the surface to be cleaned at high velocity. The ionization device (7) produces positive as well as negative ions in the laminar air jet in order to neutralize the electrostatically-charged dust particles. An air suction nozzle (3) with a corresponding suction slot (4) is arranged at a short distance from the blowing slot (2) and is operatively associated with a flat brush (5) projecting from the appliance, which serves as a baffle, determining the distance of the appliance from the surface to be cleaned, limiting the gap enclosing the laminar air jet and, to a large extent preventing sucking-in of the surrounding air. This arrangement is designed as a portable and industrial cleaning appliance.

Abstract: ABSTRACT OF THE DISCLOSURE     A tire changer has a base on which is mounted a rim and tire assembly support table upon which tires are inflated through an air inflation hose.  A rigid arm-like member is pivotally attached to the base of the tire changer in a position so that it may be pivoted between a safety position overlying the support table and a rim/tire assembly thereon and a stowed position away from the support table.  In one embodiment the rigid arm pivots from an overhead position to the safety position and in another embodiment the rigid arm pivots from a lateral position to the safety position.  The rigid arm carries the air inflation hose with a short length of the hose extending therefrom, so the arm must overlie the support table for the hose to reach the inflation valve on a tire supported on the table.

Abstract: ABSTRACT OF THE DISCLOSURE           This is directed to a modulator for a modem.  The modulator converts a bit stream, in which a predetermined number of bits form a symbol, into a phase modulated intermediate frequency (IF) signal.  To perform this function, the modulator converts the bits of the bit stream that form symbols using phase locked DPSK.  The phase modulated symbols are digitally filtered to produce a filtered signal that includes time shared, digital in-phase and quadrature-phase components that, when converted to an analog signal, provides a modulation signal of a frequency that is centered about a predetermined frequency and deviation from that frequency is according to the value of the phase modulated symbols.  The filtered analog signal is filtered again and then passed to a mixer for up-conversion to the IF signal.
