IPC: G05D23/275
Filed: 1988-04-15
Abstract: An automatic vending machine has refrigerating 16 and 
heating 17 means. The path of the refrigerated or heated 
air flow within the storage chamber of the vending machine 
is automatically varied by a temperature-dependent air flow 
control device 21. The air flows upwardly through a gap 20 
between columns 12 of merchandise, and back through a duct 
19 that opens adjacent the top of the columns and 
preferably also has an intermediate opening 31. A baffle 
plate 22 may be displaceable to obstruct the gap 20 and/or 
a cover plate 33 may be displaceable to control the 
intermediate opening 31. The displacement may be 
controlled by a pair of opposed spring elements 25,26, one 
of which is formed of shape memory alloy, so that the 
combined effect changes sense at a threshold temperature.

IPC: G06F11/10
Filed: 1988-08-30
Abstract: A fault tolerant computer system includes a fault tolerant 
data processing module which has means for detecting and cor­
recting errors in the operation of the data processing module to 
maintain a high degree of data integrity. Data transmission con­
trol devices control the transmission of all data to the fault 
tolerant data processing module and the receipt of all data into 
the fault tolerant data processing module. Input/output termi­
nals are coupled to the data transmission control means for 
receiving and transmitting data. A non-fault tolerant 
input/output module is coupled to transmit the data to the 
input/output terminals of the fault tolerant data processing 
module. This module includes a read device for transferring data 
to the fault tolerant computing system in response to requests 
from the data transmission control devices, and a firewell for 
preventing the non-fault tolerant input/output module from 
initiating transfers of data to the fault tolerant data pro­
cessing module.

Title: The removal of ammonium salts from an aqueous medium containing the salt
IPC: C01C1/18
Filed: 1988-11-30
Abstract: A process for removing an ammonium salt such as ammonium 
nitrate from an aqueous medium containing the salt includes the 
steps of: 
   (i) providing a membrane cell in which the anode and 
cathode compartments are separated from each other by 
an anion selective membrane,    (ii) passing the ammonium salt rich aqueous medium through 
the cathode compartment,    (iii) passing an alkali solution through the anode 
compartment of the membrane cell, the alkali solution 
containing cations which will form a salt with the 
anion of the ammonium salt, and    (iv) passing an electrical direct current through the cell 
thereby causing the anions of the ammonium salt in the 
cathode compartment to pass through the anion selective 
membrane into the anode compartment.     
     The alkali solution is preferably calcium hydroxide. The 
aqueous medium is typically an effluent.

Title: Method for a calculator-controlled switching device, especially for a key-telephone exchange, in which data and telephone terminals are connectible alternatively
IPC: H04Q3/545
Filed: 1989-04-18
Abstract: A key telephone terminal (T1) connected via a four-wire line (useful connection a, b and control connection c, d) to the exchange (VE) is also connected to a subscriber line (ATn), in addition to a data terminal (fax, PC). Since when a request for a connection comes from such a device, an indication occurs both on the useful connection and on the control connection but when a data terminal is connected, an indication only occurs on the useful connection (a, b wire), the system can tell whether a data communication or a normal communication exists. If a data communication is recognised, a temporary data protection is put into effect during the period of time of data transmission. Thus, the relevant subscriber connection is blocked for particular service features which can be activated by the system or by another subscriber (for example call insertion, call waiting and intrusion). Follow-up functions of manipulations at the key telephone terminal which are transmitted via the control connection are also suppressed during the existence of the temporary data protection. <IMAGE>

Title: Ophtalmic lens
IPC: G02C7/02
Filed: 1989-11-28
Abstract: In an improved ophtalmic lens which includes a pair of 
front and back refractive surfaces (1, 2), the curvature of 
the meridian of the front or back refractive surface sub­
stantially increases as far as at least 15 mm in the di­
rection of the outer periphery of the lens from the optical 
axis. The curvature of the meridian may increase monotoni­
cally within the extent of at least 15 mm from the optical 
axis in the direction remote from said axis. Further, when 
the curvature of the meridian is represented by C (r) as a 
function of the distance r from the optical axis, the li­
near differential coefficient dC/dr of the function C may 
increase at least once and then decreases as getting re­
moter from the optical axis. The improvement is to make the 
edge of the lens thinner so as to present a good appearance 
with maintaining a superior optical efficiency.

Patent EP-0337588-A3 (EP)
Title: Mri compensated for spurious nmr frequency/phase shifts caused by spurious changes in magnetic fields during nmr data measurement processes
IPC: G01R33/58
Filed: 1989-01-10
Abstract: At least one extra NMR measurement cycle is performed without any imposed magnetic gradients during readout and recordation of the NMR RF response. Calibration data derived from this extra measurement cycle or cycles can be used for resetting the RF transmitter frequency and/or for phase shifting other conventionally acquired NMR RF response data to compensate for spurious changes in magnetic fields experienced during the NMR data measuring processes. Some such spurious fields may be due to drifting of the nominally static magnetic field. Another source of spurious fields are due to remnant eddy currents induced in surrounding conductive structures by magnetic gradient pulses employed prior to the occurrence of the NMR RF response signal. Special procedures can be employed to permit the compensation data itself to be substantially unaffected by relatively static inhomogeneities in the magnetic field and/or by differences in NMR spectra of fat and water types of nuclei in imaged volumes containing both.
Patent EP-0370834-A3 (EP)
IPC: G01D13/10
Filed: 1989-11-27
Abstract: A semiconductor device has a device section 
(100) and a peripheral section (90) outside the 
device section. A main vernier pattern (30) is 
formed in the peripheral section for inspecting finely 
an alignment state in a first direction (e.g. X), and 
a subsidiary vernier pattern (130) is formed in the 
peripheral section near the main vernier pattern for 
inspecting coarsely an alignment state in a second 
direction (Y) at right angles to the first direction. 
Thus within a single field of view of a microscope, 
the misalignment can be detected in one direction 
with sufficient accuracy to provide a measurement 
correction, and in the other direction with enough 
accuracy to judge whether the product is good or bad.

IPC: H04B10/29
Filed: 1990-08-23
Abstract: In an all-optical data network, a plurality of subscriber stations are to be able to communicate with one another bidirectionally via the same optical waveguide and only one type of electro-optical circuit arrangement is to be used. The optical amplifiers (OVn, OVn+1, ...) incorporated in the optical waveguide network are equipped with additional input and output circuits for electric signals and are set up for the operating modes "Optical amplification/simultaneous reception signal conversion/transmission signal conversion". They are located at the subscriber terminal stations and replace the optical couplers and different opto-electronic components found in conventional networks. In the lasers in the optical amplifiers (OVn, OVn+1, ...), the optical strip line conductor also operates bidirectionally. The optical waveguide network does not therefore need to be designed as a closed ring and can be extended as required. Use as a local area network, processor bus system etc. <IMAGE>
