Patent NO-170386-C (NO)
Inventor: JONES GARY V
IPC: A23F5/50
Filed: 1988-10-10
Abstract: This invention is designed to obtain desirable flavor and aroma volatiles during processing of an aqueous coffee extract obtained from roasted and ground coffee. The overall process of preparing soluble coffee by spray drying a concentrated aqueous extract is improved by employing a stripper to remove up to 20% of the extract prior to concentration and to recover non-condensible and condensible aromas in cold water using an absorber having 4-48 plates and a 0.1/l to 30/l L/V ratio prior to reintroducing the absorbed aromas into the concentrated coffee extract and spray drying it to give an aromatized dry soluble coffee.

Title: Novel enzyme
Inventor: SQUIRRELL DAVID JAMES
IPC: C12Q1/26
Filed: 2000-10-26
Granted: 2004-11-18
Abstract: A recombinant protein having luciferase activity and at least 60 % similarity to a wild-type luciferase wherein in the sequence of the enzyme, the amino acid residue corresponding to residue 357 in <i>Photinus pyralis</i> luciferase is mutated as compared to the corresponding wild-type luciferase, such that the luciferase enzyme is able to emit light at a different wavelength as compared to the corresponding wild-type luciferase and/or has enhanced thermostability as compared to the corresponding wild-type luciferase. In general, the residue corresponding to 357 in Photinus pyralis luciferase is changed from an acidic amino acid to a non-acidic amino acid and preferably an uncharged polar amino acid such as tyrosine. Mutant luciferases in accordance with the invention can produce a large (50nm) wavelength shift in emitted light and have good thermostability. The resultant colour shift can be reversed by addition of coenzyme A. These properties make the mutant particularly useful in a variety of assays.

Abstract: CONTROL METHOD FOR AUTOMATIC  TRANSMISSION GARAGE SHIFTS         ABSTRACT OF THE DISCLOSURE         Garage shifts are accomplished at shifts from neutral to forward or reverse or between forward and reverse.  An off-going clutch is released at the beginning of the shift for shifts between forward and reverse; shifts from neutral have no off-going clutch. The on-coming clutch has a fill time at maximum pressure, a lower increasing pressure ramp to begin engagement as indicated by pullup or pulldown, and a closed-loop control triggered by pullup or pulldown. The closed-loop control commands the pressure to control the turbine speed to a calculated profile to bring the speed to a target value.  When the target value is attained the closed-loop control is terminated and maximum pressure is applied.  For low speed shifts and for a high speed shift between forward and reverse, the target value is zero.  For high speed shifts from neutral the target value may be either above or below the initial turbine speed.

Abstract: method to control the opacity of sheet formed of nonwoven material involves providing a computer with a steam pressure measurement from each of two steam heated palmer bonders. One pressure sensor from the first bonder drum and one from the second bonder drum provide signals used to control steam pressure and thus temperature of each bonder drum s surface. A signal indicating temperature of the surface of each drum and a measurement of speed are also collected by the computer/controller. The fundamental control signal is provided to the computer from an opacity sensor device which is compared to an opacity aim and then steam pressure to the bonder drum is adjusted to minimize any error signal between opacity aim measured opacity.

Filed: 1990-12-21
Granted: 1994-11-15
Abstract: The invention relates to a method for supplying various departments of a large self-service store equipped with a number of shopping carts with department-specific information. Each of the items of information specific to a department of predetermined length, is digitally stored in memory in decentralized fashion in a transmitter/receiver unit assigned to the particular department and then transmitted in a predetermined cycle in serial form over an infrared path. By means of receiver/transmitter units mounted on all the shopping carts of the store, the transmitted information is received by the receiver/transmitter units of the shopping carts located in the particular department, stored in buffer memory there, and reproduced on a display of the receiver/ transmitter units.            Immediately after each playback of information specific to a particular department on the display of the receiver/transmitter mounted on the associated shopping cart, a signal confirming this visual playback of information is transmitted via the infrared path to the transmitter/receiver unit provided in that particular department and recorded there.

Title: Method of determining sampling time points
Inventor: LARSSON LARS GUSTAV
IPC: H04L7/02
Filed: 1990-10-26
Granted: 2001-01-09
Abstract: Symbol sequences having synchronization sequences are transmitted over a radio channel. Received signals are sampled in signal sampling time points (n) and by correlation a channel response (C2) is obtained. The impulse response is sampled (T) over a period (M x N) corresponding to time dispersion of the channel. For separate samples with separate start points (n), channel estimates are obtained (n - 0, 2, 4, 6, N = 1, 3, 5, 7,...) whose energy values are calculated, and the estimate (n = 8, 10, 12, 14) with the largest energy is selected. The first time point (n = 8) in this estimate is selected as sampling time point for the symbol sequence. Alternatively, the signal sampling time point (n = 9) with maximum energy value (C2 max) is selected. By comparing the energy values either one of these signal sampling time points (n = 8, n = 9) can be selected as the sampling time point for the symbol sequence. For consecutive sequences, an average value for the sampling time points is calculated. Maximum energy of received symbols and simplified signal processing are obtained.

Title: Grain dryer
Inventor: LOYNS RONALD A
IPC: F26B9/10
Filed: 1991-06-19
Granted: 1993-08-17
Abstract: ABSTRACT OF THE DISCLOSURE          The apparatus provides a recirculating normal batch, concurrent flow, grain dryer and an alternate small batch countercurrent flow grain dryer.  Hot drying air is provided by an external conventional burner and air fan.  For the normal batch, the hot air is forced to a central plenum in the grain holding bin where it radiates outwardly into horizontal conduits then passes downwardly through the grain as it moves under gravity and exits at a lower lever to the atmosphere through horizontal conduits.  The gravity forced flow of grain is recirculated to the bins upper area by a centrally located elevating auger.  A pivotal roof portion of the hot air inlet flues when pivoted downwardly provides a countercurrent alternate path for the hot air for small batch drying.  "V" plate ribs support an inverted "V" ring cone on the lower and inner cone of the bin for proper grain flow control.

Title: Electronic apparatus and method for grounding electronic apparatus
Inventor: WATANABE HARUO
IPC: H01H3/16
Filed: 1991-09-18
Granted: 1999-01-19
Abstract: An electronic apparatus which is placed in an operation wait state by fully closing a cover having an electrical component, and a method for grounding the electronic apparatus is disclosed.  The apparatus includes a cover-side contact element electrically connected to the electric component, and a body-side contact element electrically connected to a grounding member of the apparatus. Both contact elements are brought into contact with each other so as to electrically connect the electrical component with the grounding member of the apparatus when the cover is fully closed.  Thus, grounding of the electrical component can be ensured without using a conductive wire for connecting the electrical component with the grounding member of the apparatus.  Furthermore, a malfunction of the electrical component caused by an electrostatic charge is prevented, while reducing troublesome assembly work and the number of components.  In addition, since the apparatus includes a switch comprising a displacement element provided on at least one of the two contact elements, the opened and closed positions of the cover can be detected in response to a displacement of the displacement element. Thus, an exclusive switching unit such as a microswitch and an operational member for actuating an actuator of the switching unit are not required.  The apparatus can therefore detect a full closed position of the cover without increasing the number of components and the overall size of the apparatus.
