Title: Method of and apparatus for cooling and dispensing beverage
Inventor: HASSELL DAVID A
IPC: B67D3/00
Filed: 1985-06-17
Granted: 1992-03-03
Abstract: ABSTRACT OF THE DISCLOSURE       A beverage cooling, carbonating and dispensing apparatus has a refrigerator cabinet having a cold air cooling chamber, a cold beverage reservoir and carbonator in the cooling chamber, an outlet from the reservoir to a dispensing valve, and a thermally conductive precooler in a beverage inlet to the reservoir, the precooler is in the cold air chamber and has a substantial restriction to flow of beverage therethrough so that the refilling flow into the reservoir is very slow and is cooled to about 40 degrees F (4.4 degrees C) before admittance into the reservoir, so the entire contents of the reservoir can be dispensed without warmup or loss of carbonation.     A method of cooling, carbonating and dispensing beverage has the steps of storing a supply of previously pre-cooled beverage in a reservoir, dispensing servings of beverage from the reservoir, replenishing the reservoir with new beverage at an incoming flow rate substantially les than the dispensing flow rate by restricting the incoming flow to a trickle and pre-cooling the trickling flow while cooling the reservoir, and carbonating the cold trickling flow upon admittance to the reservoir.       This apparatus and method substantially increasing the dispensing capacity.

Title: Electric arc melting apparatus and associated method
Inventor: MATHEWS DAVID R
IPC: F27D11/08

Granted: 1990-12-18
Abstract: ABSTRACT OF THE DISCLOSURE           Electric arc apparatus and an associated method are provided.  Pairs of aligned cooperating coils are positioned on opposed sides of a crucible.  In a preferred embodiments three such pairs which overlap each other are employed so as to sequentially generate magnetic fields so as to provide a uniform magnetic field which will rotate the arc between the electrode and the crucible interior in a first direction.  The arc rotation may be reversed.  It is preferred that the maximum magnetic field created by each pair of coils be out of time phase with respect to the other coil's magnetic field.  This apparatus and the associated method serve to resist undesired irregularities in the ingot exterior surface which irregularities would require subsequent treatment and result in loss of metal.

Granted: 1989-09-26
Abstract: A downhole self-contained memory gauge includes either a semiconductor or magnetic core memory for retaining downhole information related to sampled parameters, such as borehole temperature and pressure. A microprocessor-based computer manages the power utilization by independently and selectably energizing and de-energizing different sections of the gauge. The magnetic core memory is tested for operability, and the addressing of the magnetic core memory is adjusted in accordance with any inoperable memory locations. Samples of the monitored environmental conditions can be taken at variable rates dependent upon software monitoring of the condition, the remaining battery life and the remaining memory capacity and in response to hardware monitored pressure changes. Each sample can be taken to a selectable resolution. A watchdog circuit monitors the microprocessor to ensure that it is operating within a preselected time limit.

Patent CA-1336655-C (CA)
Inventor: DAVIES NEIL
IPC: G02B30/27
Filed: 1986-11-14
Granted: 1995-08-15
Abstract: The  invention  relates  to  the production of three dimensional images for direct viewing or for recording on a sensitised recording surface. Hitherto, three dimensional images have been produced by a two-stage process, and the resultant images have needed to be viewed using special equipment.  To produce such images in e.g. photography, either a multiple lens camera has been needed, or a means to allow a single lens camera with a slit plate, to move along a horizontal track.  The images so produced exhibit a high degree of so-called flipping. More recently, an attempt to overcome these problems proposed the use of a wide aperture lens behind a slit plate.  This allows the object to be viewed from various and continuous directions but the image is a spatial image that is inverted in depth, and the process remains as a two-stage process. The object of the present invention is to provide a method and apparatus for the direct production of integral parallax orthoscopic panoramagramic images, which objective is met by a process comprising directing at an object a means of  gathering and focussing incoming radiation from the object of a wavelength to which said means is suited, positioning to either side of said gathering and focussing means a grouping means for producing a number of groups of individual waves, each group emanating from a part of said object, said grouping  means  generating  an  image  in pseudoscopic form, and  a means of encoding the pseudoscopic image as discrete parallactic information on a single plane, for subsequent viewing as an orthoscopic image.

Abstract: ABSTRACT                 POLYSILICON PROCESS AND PRODUCT          A polysilicon process is disclosed in which the fines which are inherently produced in a fluid bed deposition type operation using silicon seed particles and a silane feed are in effect glued on to the product part-icles so as to reduce the undesirable effect of the silicon fines.  The process comprises operating a fluid bed in two modes.  In the first mode, high productivity is favored at the expense of producing fines which are produced by homogeneous decomposition of the silane feed.          In the second mode, the fines are in effect glued on to the particles to which they are adhered by means of deposition of a thin layer of silicon.  In the second mode, the concetration of the silane in the feed gases is reduced thus favoring hetergeneous deposition of the silicon on the silicon particles in the bed.  The process can be operated using a single fluid bed reactor by alternating cycles or in a more continuous manner utilizing two fluid bed reactors, the first reactor being operated at the high productivity rate with the second reactor taking the silicon particles from the first reactor and operated at the gluing on conditions.

Title: Anti-lockup drive mechanism for a position controlled linear actuator
Inventor: ABRAHAM WILLIAM F
IPC: F16H25/20
Filed: 1987-08-28
Granted: 1992-02-04
Abstract: Abstract of the Disclosure A linear actuator is provided with an electric motor rotating a drive pinion gear in mesh with an intermediate gearing arrangement which in turn is in mesh with a main drive gear for rotating a drive screw journalled within a main body housing. Rotation of the drive screw causes longitudinal advancement of a drive nut axially advancing an extension rod bearing to move an output load connected to an opposite end of the extension rod. The intermediate gearing arrangement includes a lost motion mechanism allowing the drive pinion to complete approximately one revolution before imparting rotative torque to the drive screw allowing the drive motor to develop an operating torque to prevent lockup of the actuator. The lost motion mechanism includes a pair of arcuate slots formed in a first intermediate gear in contact with the drive pinion and a pair of dowel projections projecting from a second intermediate gear into the slots. The second intermediate gear is connected to the drive screw. Upon actuation of the drive motor, the first intermediate gear rotates through a predetermined angular interval until the dowel projections move from one extreme position in the associated slot to the opposite extreme position at which time an abrupt force is imparted to the second intermediate gear to rotate the drive screw.
