Title: Arrangement for decoding signals
IPC: G08G1/09
Filed: 1988-04-21
Abstract: In an arrangement for decoding signals which are received in addition to other signals as a modulation of radio waves and whose respective frequency constitutes a specific item of information, a time basis signal of constant frequency is generated from which a reference signal with a controllable frequency position and phase position is derived with the aid of a microprocessor. An output signal is derived if there is a coincidence of the reference signal with the received signal with respect to phase and frequency. The time basis signal can preferably be derived from the instruction frequency of the microprocessor by running through program loops of identical length at least in the timing means. A register which is incremented by changeable values serves for deriving the reference frequency. In the case of two superimposed signals, the one is evaluated with respect to frequency and the other with respect to the pulse duty factor of a binary signal. <IMAGE>

Title: Simplified calibration for a distance information obtaining device
IPC: H04N7/18
Filed: 1988-08-05
Abstract: In a distance information obtaining device 
comprising an image pickup device (10) for picking up an 
optical image of an object to produce a picture signal, 
and a signal processing unit (18) for processing the 
picture signal to produce a processed signal 
representative of distance information between the image 
pickup device and each point of the object, the signal 
processing unit produces a reference signal by using a 
reference picture signal derived from the image pickup 
device on a preliminary process. Responsive to the 
reference signal, a preliminary processing unit (26) 
preliminarily processes the reference signal to produce 
a preliminary processed signal as a calibration signal. 
In a measuring process, the signal processing unit 
processes the picture signal with reference to the 
preliminary processed signal. Preferably, the reference 
picture signal should be given in the form of first and 
second reference picture signals derived from first and 
second reference optical images of first and second 
reference plates (16) and (16′) located at first and 
second distances (Z a ) and (Z b ) from the image pickup 
device.

Title: Cellulose acetate butyrate gas separation membranes
IPC: B01D71/00
Filed: 1988-10-15
Abstract: Cellulose acetate butyrate gas separation membranes are prepared from a casting solution containing from about 10 to 30 percent polymer, 35 to 70 percent solvent, and 15 to 30 percent pore-forming agents. A film casting solution is cast onto a substantially flat support surface and a dense layer is formed on the exposed film surface. The film is gelled, washed, and dried to produce a particularly useful gas separation membrane. The cellulose acetate polymers used in this preparation have molecular weights of at least about 20,000, and have about 10 to about 45% butyryl groups, about 2 to about 35% acetyl groups, and about 0.8 to about 2 percent hydroxyl groups, by weight. The membranes may be used for separating a feed gas into a permeate fraction and a residual fraction, and are particularly useful for separating gases in the purge gas stream of ammonia plants to recover a permeate which is relatively rich in hydrogen. Cellulose acetate butyrate membranes may be used to improve the separation of ammonia plant purge gases which contain ammonia as well as hydrogen and nitrogen, especially when there is no pretreatment of the purge gas to remove ammonia gas.

Patent EP-0325033-A3 (EP)
Title: Adhesive insertion pockets with guiding features
IPC: B42D5/02
Filed: 1988-11-23
Abstract: The invention relates to adhesive insertion 
pockets of a web material where used as the basis 
is a self-adhesive material, for instance a rein­
forced paper web (102a) which has been detachably 
attached to a web shaped substrate (101). By 
means of appropriately punching or incising the 
paper web, a piece for an insertion pocket (102b) 
emerges which, on being torn from the substrate 
(101) and being adhered for instance to the inside 
cover of a book (108) will form an insertion 
pocket where an incision for the mouth (103a) 
forms the mouth of the pocket and the size of the 
pocket is determined by a cut away section (104) 
on the substrate web (101) which when detached, 
remains on the piece for the insertion pocket 
(102b) to form a non-adhesive area of the pocket. 
In order to achieve ready entry of the card (110) 
to be inserted into the pocket, the entrance in­
cision has been made as an elongated circumferen­
tial opening incision (103a), and to achieve an 
area at the bottom of the pocket (104c) affected 
as little as possible by exposure of zones of 
glue, penetrating incisions (104s, 104m) have been 
made in the area of the bottom of the pocket, re­
ducing this bottom area and thus reducing the pos­
sibility of adhesion by the cards to the bottom of 
the pocket.

Title: Method for recycling fluorescent lamps and tv tubes
IPC: B03B9/06
Filed: 1988-06-24
Abstract: To recycle fluorescent and television tubes, the latter are introduced into a container which can be sealed in a gas-tight manner and crushed under water. In this process, the ascending gases released are drawn off under suction and fed in a compressed state to the reuse process, acid which dissolves or strips off the pollutants being added to the broken glass, which is coated with pollutants, the dissolved and stripped-off pollutants are flushed out of the broken glass, the metallic constituents are removed therefrom and then the broken glass is passed to the further utilization process. A precipitating agent is added to the liquid phase and the liquid phase is then filtered, the yttrium-containing filter cake being delivered to lanthanide manufacturers for further processing. The filtrate is fed back to the container in which the tubes are crushed.

Title: Method for regulating the temperature of an adjustable-temperature and variable-crown roll and a temperature-regulation system intended for carrying out the method
IPC: F16C13/00
Filed: 1989-02-09
Abstract: The invention concerns a method for regulating the temperature of an adjustable-temperature and variable-crown roll. In the roll (10), the roll mantle (12), arranged to revolve on the stationary roll axle (11), is loaded by the intermediate of a pressure medium so as to correct the deflection of the roll mantle (12), and, moreover, the roll (10) is heated by means of heating fluid passed onto the inside face of the roll mantle (12). The heating fluid is passed into the roll (10) to the areas of the roll mantle (12) from which heat is removed out of the roll (10) by means of conduction in the radial direction of the roll, i.e. to the areas in which the direction of the flow of heat is radially away from the roll. From the hot areas in the roll mantle (12), i.e. from the areas from which heat is not removed by conduction in the radial direction away from the roll mantle, heat is again removed by passing cooling fluid to said hot areas. The heating fluid is passed into the roll (10) so that the heat passed into the roll is distributed in the axial direction of the roll in a corresponding way as compared with the flow of heat removed from the roll (10), and cooling fluid is passed to the hot areas in the roll (10) in the same proportion as heat flows to said hot areas from other parts of the roll (10). The invention further concerns a temperature-regulation system intended for carrying out the method.
