Title: Apparatus for making and handling pieces of dough
IPC: A21C5/02
Filed: 1983-07-06
Abstract: A device and a method for the manufacture and processing of biscuit mixture shapes, including pressing pick up devices by means of a drive with their forming chambers against the floor of a trough filled with biscuit mixture, and while there, rotating them by means of a drive by 360 DEG , while a drive turns the trough somewhat further. Subsequently the pick up devices are raised and placed by a drive in a position above a band conveyor with baking sheets. By means of a drive the ejectors are then moved into the forming chambers and the formed biscuits are deposited by stripping device onto the baking sheet. The baking sheet is fitted with recesses of specific design. The band conveyor transports the formed biscuits into a plant comprising an oven, a cooling device, a second heating device, a removal device and stacking chambers for baking sheets. The removal device is largely identical with the mixture pick up device. The trough receives a supply of mixture which is controlled by a level indicator.
Patent EP-0104536-A3 (EP)
IPC: H01Q3/46
Filed: 1983-09-13
Abstract: A passive array of resonantly-dimensioned microstrip 
antenna radiator patches are closely spaced (i.e., less than 
one-tenth wavelength) above a ground plane and individual­
ly associated with transmission line segments terminated so 
as to cause the overall array to receive an incident r.f. 
electromagnetic field, to convert the received field into r.f. 
electrical currents which flow along the transmission lines 
and are absorbed by the terminations or reflected therefrom. 
In the latter case, the reflected r.f. energy is re-transmitted in 
a predetermined direction as a redirected r.f. electromagne­
tic field. The presently preferred embodiment is a relatively 
thin, flexible and thus conformable layered structure formed 
by selectively etching conductive material from one side of a 
metallically cladded dielectric sheet. For satellite communi­
cation, a flat reflectarray may be associated with a primary 
r.f. transmitter/receiver structure disposed at a focal area or 
spot of the reflectarray having an appropriately phased 
aperture (e.g., parabolic). For radar cross-section enhance­
ment or reduction, the reflectarray aperture is phased so as 
to retro-reflect incident r.f. fields or so as to scatter, 
otherwise misdirect or absorb (e.g., by using lossy resistive 
transmission line terminations) the incident r.f. field.

Patent EP-0129697-A3 (EP)
Title: Method of making printed circuit boards
IPC: H05K1/16
Filed: 1984-05-17
Abstract: The present invention describes an improved reverse lamination process for preparing printed circuits with resistors, conductor strips and/or contacts integrated in the circuit. A separating layer is applied on a metallic intermediate carrier. The intermediate carrier thus coated is then printed with a conductive paste in a desired. mirror-inverted layout to provide the resistors, conductor strips and/or contacts. This is followed by the lamination which is carried out under temperature effect and under pressure, the thus laminated package comprising the intermediate carrier, an intermediate layer and the final substrate. The intermediate carrier is subsequently removed, and the separating layer is etched off. The separating layer acts as a parting agent to permit easy mechanical separation and reuse of the metallic intermediate carrier.
Patent EP-0138530-A3 (EP)
IPC: C12Q1/00
Filed: 1984-10-05
Abstract: A method for the estimation of a salicylate or a reduced 
pyridine nucleotide (especially NADH or NAD(P)H) in a sample 
consisting of enzymically converting a salicylate to a catechol 
by the action of a salicylate mono-oxygenase enzyme on the 
salicylate in the presence of a reduced pyridine nucleotide, 
reacting the catechol with an aminophenol, preferably para­
aminophenol, to form an indophenol and estimating the quan­
tity of the indophenol spectrophotometrically, the quantity of 
the indophenol being a measure of the salicylate or reduced 
pyridine nucleotide in the sample.  
     A diagnostic kit to allow the routine use of the method is 
also provided.

Title: Improved apparatus for measuring varying density of a slurry flowing in a pipeline
IPC: G01N9/06
Filed: 1984-12-04
Abstract: An improved apparatus is disclosed which employs hydrostatic bearings for measuring varying density of a fluid, usually of a slurry of coal or minerals, flowing in a transport pipeline. A first pipe section is fixedly interposed in the fluid carrying pipeline. A second or centre pipe section is horizontally mounted within the first pipe section substantially coaxially therewith and to be in fluid communication with the fluid or slurry transporting pipeline whereby the transported fluid flows through the second or centre pipe section. Ends of the second or centre pipe section and adjacent ends of the transport pipe, or of intermediate pipe pieces conventionally coupled to the transport pipe, are machined and configured to be capable of functioning as hydrostatic bearing surfaces in a direction normal to the longitudinal axis of the centre pipe section. A substantially ring-shaped chamber is disposed between the first and second pipe sections into which hydrostatic fluid is pumped under pressure through an inlet port provided in the first pipe section. The hydrostatic fluid flows through suitable ducts inwardly to the hydrostatic bearing surfaces, whereby motion of the centre pipe section is substantially frictionless in the vertical direction. Weight of the centre pipe section and of the fluid contained therein is measured by load cells, or strain gauges or the like. Preferably, the weight is obtained by accurately measuring vertical displacement of the centre pipe section against the force of preloaded tension rods which mount the centre pipe section to the enveloping first pipe section.

Patent EP-0122244-A3 (EP)
Title: A lock system
IPC: E05B49/00
Filed: 1984-03-30
Abstract: The invention relates to a lock system for rooms which are to be made exclusively accessible to different uses over different periods of time, for example hotel rooms. The keys of the system comprise magnetic cards which are provided with magnetically registered data, which for each card includes lock-identification data valid for a given lock or a given group of locks, a validity time expressed in real time and a randomly selected legitimacy code. Each lock includes an electrically actuable lock mechanism (4), a magnetic-card reader (3), a memory (6) for the storage of data, a real-time clock (7), a programming unit (10), a legitimacy comparator (8), and a time comparator (9). The memory (6) has stored therein the lock-identification data valid for the lock. When a magnetic card is introduced for the first time into the card reader (3) of a lock, the legitimacy comparator (8) compares the lock-identification data registered on the card with the lock-identification data stored in the memory (6), and the time comparator (9) compares the validity time registered on the card with the real time given by the real-time clock (7). If these comparisons show agreement, the lock opens and the programming unit (10) is instructed to store into the memory the validity time and the legitimacy code registered on the card. When a magnetic card is later introduced to the card reader (3) the time comparator compares the real time given by the real-time clock (7) with the validity time in the card data stored in the memory and the legitimacy comparator (8) compares the data registered on the card with the data stored in the memory (6) of the lock, and the lock is opened when agreement is found between the data compared. If the comparison made by the time comparator (9) show disagreement, the time comparator compares the validity time registered on the card with the real time given by the real-time clock (7) and the legitimacy comparator (8) compares the lock-identification data registered on the card with the lock-identification data stored in the memory and, if these comparisons show agreement, the lock is opened and the programming unit (10) is used to replace the card data already stored in the memory (6) with the data registered on the card.
