Patent EP-0225069-A3 (EP)
Title: Telephone power supply
IPC: H04M19/08
Filed: 1986-11-05
Abstract: To provide an adequate dc supply to the electronics of a telephone, when on hook or off hook, there is a transistor (T2) with its emitter-collector path in one line wire, and a storage capacitor (Cpsu) across the input to the telephones's circuits. This capacitor is charged up and maintains dc supply when the line voltage (at A) falls below a preset level. The base of this transistor is connected via another transistor (T1) to the other line wire. The speech output (VIN) is connected via an operational amplifier (A) to the base of the second transistor (T2). Hence the dc supply and the speech output are in parallel.
Patent EP-0263926-A3 (EP)
IPC: B65H37/00
Filed: 1987-07-21
Abstract: The invention is an improved dispenser (71) for a transfer 
adhesive which is separated from its backing material and 
transferred onto a working surface, without the backing. 
The adhesive and backing are initially formed on a tape 
(87) which is threaded from a supply reel (75), and around 
a tape roller (79), the spent backing being wound on a 
take-up reel (77). The adhesive is applied by rolling the 
tape roller (79) along the working surface. The tape roller 
(79) is attached to a lever (91), which in a first position 
prevents the supply reel (75) from rotating, and in a 
second position allows the supply reel (75) to rotate. The 
lever (91) is spring-biased so that it is normally in the 
first position. When the tape roller (79) is pressed 
against the working surface, so as to apply the adhesive, 
the lever (91) shifts to the second position. Thus, the 
dispenser (71) is automatically enabled when one begins to 
use it, and is automatically disabled when the dispenser 
(71) is put aside.

Title: Process for the production of thermally stable layers wiprocess for the production of thermally stable layers with a great hardness and/or low-friction properties th a great hardness and/or low-friction properties
IPC: C23C14/06
Filed: 1988-12-01
Abstract: A process for the production of layers which have great hardness and/or low-friction properties, in particular based on micro- or nanodisperse carbide carbon layers, is proposed. A target material to which an electric potential is applied is converted in a vacuum into a target plasma. The target plasma reaches the substrate which is at an electric potential approximately equal to or higher than that of the target material and forms the desired layer on said substrate. The target material is formed by a titanium alloy, the titanium alloy being vaporised by means of an arc to give a titanium alloy plasma. The conversion of the titanium alloy into the plasma is carried out in the gas phase of ionised carbon. The process is operated by a method in which titanium alloy carbide, gaseous titanium alloy and carbon are formed, the carbide of the titanium alloy, the titanium alloy and carbon being formed, in succession on the substrate, as a ternary layer which additionally has thermal stability.

Patent EP-0297878-A3 (EP)
IPC: F16J15/43
Filed: 1988-06-28
Abstract: A compact long-life magnetic fluid seal for 
sealing between a housing (32) and a magnetically 
permeable rotating shaft (30) includes an annular magnet (36) 
having a closely-spaced, noncontacting relationship 
with the shaft (30) to define a first gap (40) and an annular 
pole piece (42) axially abutting the magnet (36) and having a 
closely-spaced, noncontacting relationship with the 
shaft to define a second gap (50). The first gap (40) has a 
slightly larger radial dimension than the second 
gap (50), and the first (40) and second gaps (50) together define 
an elongated annular space for retention of a 
magnetic fluid (52). The outer edges (54) of the pole piece (56) 
and magnet (36) inner surfaces can be rounded to limit 
splashing of the magnetic fluid (52). In another 
embodiment, a magnetic fluid seal includes first and 
second pole pieces (72,74) axially abutting opposite ends of 
an annular magnet (70). The magnet (70) has a slightly larger 
inside diameter than either of the pole pieces (72,74). The 
pole pieces (72,74) and the magnet (70) together define an 
elongated annular gap for retention of magnetic 
fluid (78). The seal structure permits introduction of a 
relatively large volume of magnetic fluid (78), thereby 
extending the seal life, while maintaining a short 
axial dimension.

Title: Display device
IPC: G02F1/133
Filed: 1988-12-01
Abstract: A display device has a lattice of pixel elements each selectably settable. A method of operating the display device comprises the steps of receiving a signal representing a picture for display during a display period and illuminating the lattice to produce, during a first interval within the display period, a first light output from the lattice having a first predetermined colour characteristic and to produce at least one additional light output from the lattice. Each said additional light output has a different predetermined colour characteristic and a respective interval within the display period separate from the first interval. The method further comprises the step of time-multiplex addressing blocks of pixel elements a plurality of address times during each interval. The addressing step includes setting a group of blocks, the group consisting of a plurality of blocks spaced apart in the addressing sequence such that the blocks in the group form a series with adjacent blocks having a temporal separation in the addressing sequence exhibiting a geometric progression with a common ratio N being an integer equal to 2 or more. In this way, addressing of the lattice occurs simultaneously with its illumination by the appropriate colour, allowing a greater proportion of the frame time for the addressing operation so that additional addressing information can be utilised.

Abstract: An injection molding system having a number of heated nozzles (10) or probes, each with a forward nose portion (28) extending in a well (17) in an insert (18) in alignment with a gate (34) leading to a cavity. A circular cooling fluid passage (142) extends through the insert (18) around the nose portion (28) adjacent the cavity.

The insert (18) is made by integrally brazing inner and outer portions (112,114) together in a vacuum furnace. The circular passage (142) and the inlet and outlet ducts (148,150) are provided by machining appropriate grooves and bores in the inner and outer portions (112,114) before they are brazed together.

Title: Waveguide coupling arrangement
IPC: H01P1/17
Filed: 1989-07-07
Abstract: A capacitively coupled printed patch (3) as a high efficiency device to couple orthogonally polarised energy between a stripline (5) and a waveguide (1). Coupling between the stripline (5) and the patch (3) is achieved by the stripline terminating in a narrow strip probe (4), the end of which lies close to, but not in contact with, an edge of the patch (3). Two separate probes (4) arranged mutually orthogonally are used to effect independent polarised couplings to produce independent linear orthogonal signals or independent left- and right-handed circularly polarised signals. The striplines (5) and patch (3) are supported on a common substrate (8) which extends transversely through the waveguide (1). The waveguide wall has a quarter-wavelength thickness (T) so that its inner edge (10) appears continuous to energy passing through the substrate (8). One application is in a DBS satellite TV receiving system where it is required to isolate two signals sharing a common channel but having orthogonal polarisations.
