Abstract: The present disclosure provides a splash guard to minimize potential contact between the chemical product and a vent membrane during transport and/or transfer of containers, thereby resulting in preservation of the integrity of a vent membrane during transport and/or transfer of a chemical product. The splash guard is affixed to the fitment and so can be removed from the interior of the container prior to transfer of the chemical product out of the container. The splash guard may be used with fitments of varied shapes, sizes and/or structures, and with containers of varied shapes, sizes and/or structures. The splash guard is easy and inexpensive to manufacture and easy to install, e.g., by snapping onto a ring (lower perimeter) of a fitment. For example, the splash guard covers the entire circumference of the neck of a container, and is formed of a moldable material that provides rigidity.

Abstract: Methods and devices for privately verifying and enhancing location data by a distributed ledger system are disclosed. A location-based services server receives a possible location of a mobile device. A location verification system determines a detected location of the mobile device. A distributed ledger system uses a private set intersection technique to determine whether the possible location corresponds to the detected location without the possible location or detected location being shared. Probabilities associated with the possible and detected locations can also be combined to enhance the accuracy of the possible location.

Title: Spot-accurate re-engraving method for printing cylinders
IPC: H04N1/047
Filed: 1983-11-02
Abstract: A method for the topically precise subsequent-engraving of printing cylinders wherein special marks are engraved in the cylinder and evaluated. The marks are engraved in the form of cups forming a cup track. The cups serve as reference marks for an axial feed and start of the subsequent-engraving in a circumferential direction. After the printing cylinder has been mounted in an engraving machine for subsequent-engraving, the cylinder is placed in rotation and the scanner is moved over the previously engraved cup track axially. A maximum of the signals received from the scanner is identified and a location of the maximum in the cup track is retained as a reference value for the axial feed during the following engraving. A cup track is provided with at least one defined gap that is free of cups. A first cup following the gap is identified by means of the scanner and evaluated as a reference location for a start of engraving in the circumferential direction for the following subsequent-engraving.

Title: High frequency distribution network
IPC: H03H7/48
Filed: 1984-12-21
Abstract: The invention starts from a device for dividing high-frequency energy between two mutually decoupled outputs (A1, A2) with matched impedances, with a matching transformer (Ü1) and a differential transformer (Ü2) as well as a decoupling impedance. To achieve a broadband high decoupling of the two outputs (A1, A2) with good matching of all terminals in as simple and inexpensive a manner as possible, two possible circuits are proposed: In the first embodiment the decoupling impedance is an ohmic resistor (R1) which is connected between the connection point of the matching transformer (Ü1) and one of the two outputs (A1, A2) in the case of symmetrical distribution, and the output with the higher resistance in the case of non-symmetrical distribution, its magnitude and the location of the tapping being selected in such a way that both the decoupling of the two outputs (A1, A2) and the return loss have an optimum value at the output with the higher resistance. In the second embodiment of the distribution network according to the invention, the series circuit of an ohmic resistor (R2) and a reactance (L) with a resonant frequency of approximately 50 MHz is connected between the two outputs (A1, A2). <IMAGE>

Abstract: Test circuitry is included in a PROM memory for 
detecting shorts between bit lines and word lines and shorts 
or leaks in a memory cell. The circuitry enables a selected

memory so that the existence of leaky memory cells or 
shorts in the memory can be detected during testing. The 
test circuitry has no appreciahle effect on the memory during 
normal operation of the memory.
Patent EP-0127470-A3 (EP)
IPC: E01C7/35
Filed: 1984-05-25
Abstract: A method for applying a skid-resistant surface layer to 
roads involves the application of a layer of chippings which is 
then covered by a layer of bituminised sand. This sand fills the 
voids between the chippings such that, during subsequent 
compression with a roller, the chippings cannot rotate and 
remain in a random orientation. The resulting surface layer 
contains a relatively large proportion of chippings having a 
sharp or pointed edge uppermost and thus possesses good 
skid-resistance properties.  
     The method may be adapted either for use in the re­
surfacing of an existing road or for applying a skid-resistant 
surface during the construction of a new road.

Patent EP-0143660-A3 (EP)
IPC: H01C17/06
Filed: 1984-11-29
Abstract: This invention concerns resistor compositions, methods 
of forming such resistor compositions, and articles com­
prising a substrate carrying such resistor compositions.  
     The resistor compositions of the invention comprise car­
bon particles embedded in a matrix formed from short chain-­
length phenolic resin, long chain-length phenolic resin, epoxy 
and, optionally filler.  
     The resistor compositions of the invention can be formed 
by mixing short chain-length phenolic resin, long chain-length 
phenolic resin, solvent, and, if present, filler with carbon 
particles to form a solution which is then mixed with the epoxy 
to form an ink. The ink is applied to a substrate to form a 
film thereon which is cured to evaporate solvent and to allow 
polymerization to occur thereby leaving the resistor compo­
sition on the substrate.

Abstract: The invention provides an improvement in the yield of 
benzene and methyl-substituted benzene derivatives such 
as toluene, xylene and trimethylbenzenes by the catalytic 
hydrogenation treatment of heavy aromatic hydrocarbon 
compounds having 9 or more carbon atoms in a molecule.

catalyst which is a crystalline aluminosilicate supporting a 
metallic element selected from the metallic elements be­
longing to the VIIIth Group of the Periodic Table including 
nickel, platinum, palladium, rhodium and iridium introduced 
into the carrier by the ion exchange treatment. The hy­
drogenation treatment of the heavy aromatic hydrocarbon 
compound is effective to selectively dealkylating the alkyl 
groups other than methyl.

Filed: 1985-12-13
Abstract: Photosensitive materials are described comprising a carri­
er sheet having thereon a photosensitive layer and comprising 
a layer which becomes vesicular and remains cohesive under 
the influence of actinic radiation. When the photosensitive 
material is imagewise exposed to actinic radiation the pho­
tosensitive material becomes preferentially removable from the 
carrier sheet in the non-exposed or the exposed areas and the 
vesicle forming layer material becomes vesicular. Thus there is 
obtained an image which is immediately visible after the image-­
wise exposure step and accordingly can be used to check that 
exposure has correctly taken place and which is subsequently 
developable by removal of the non-exposed or exposed area 
material.  
     The photosensitive material according to this invention is 
particularly useful in the production of sign making materials 
and in the production of dry transfer materials using «peel 
apart» development.
