Title: Data path protection
IPC: H04B1/74
Filed: 1989-06-02
Abstract: The invention concerns a transmission system in which a plurality of data streams are to be multiplexed and sent between receiving and transmitting equipment. At the transmit end the system comprises a plurality of worker tributary cards (51, 52) each having an input port (57) connected to an individual tributary to be sent to an associated multiplexer, and a stand-by tributary card (56) operative to replace a failed worker card. All the worker tributary cards (51 - 55) are interconnected by a common line (60) leading to the input port (57) of the stand-by tributary card (56) but in normal operation being isolated from said line by a controllable unity-gain buffer 58. Each tributary to be transmitted is connected to an input port (57) of a worker tributary card and has a branch line which is connected to said common line (60) via the buffer (58) carried on another tributary card, detection of failure of a worker tributary causing the buffer (58) of the associated worker tributary card to be enabled to connect the tributary to said stand-by tributary card.

Title: Vehicle passenger seating
IPC: B60N2/75
Filed: 1989-06-14
Abstract: A vehicle multiple passenger seating unit is constructed on a support 
frame comprising two transverse parallel beams (1, 2) carried on legs (3, 4) 
having feet (5, 6) for engaging mountings on the floor of the vehicle and 
joined by two or more spaced generally horizontal longitudinal members (8, 9), 
usually at each side and between each pair of adjacent seats. The beams 
(1, 2) enter bores (10, 11) in the longitudinal members (8, 9). Side armrests 
are usually mounted on the longitudinal members at the sides of the support 
frame and intermediate armrests are mounted on longitudinal members between 
adjacent seats or on parts of the frame adjacent to those longitudinal 
members.  
     The invention provides a longitudinal member (8, 9) for such a support 
frame that is formed integrally with at least a major part (15, 16) of an 
armrest. A longitudinal member (8) for the side of a support frame which is 
to be adjacent to an aisle when the support frame is mounted in a vehicle has 
a recess (17) in its outer side, surrounding and enclosing constructional 
details, and a separate panel (19) is provided to fit in the mouth of the 
recess to conceal them. The edges (18) of the recess are undercut so that 
the panel (19) can be snapped into the recess (17) and will be self-retaining.

Title: Secure management of keys using control vectors
IPC: H04L9/00
Filed: 1989-08-09
Abstract: Arrangements are disclosed for validating that key management 
functions requested for a cryptographic key by the program have 
been authorised by the originator of the key. The invention includes 
a cryptographic facility characterised by a secure boundary (6) 
through which passes an input path for receiving the cryptographic 
service requests, cryptographic keys and their associated control 
vectors, and an output path for providing responses thereto. There 
can be included within the boundary a cryptographic instruction 
storage (10) coupled to the input path, a control vector checking 
unit (14) and a cryptographic processing unit (16) coupled to the 
instruction storage, and a master key storage (18) coupled to the 
processing means, for providing a secure location for executing key 
management functions in response to the received service requests. 
The cryptographic instruction storage (10) receives over the input 
path a cryptographic service request for performing a key management 
function on a cryptographic key. The control vector checking unit (14) 
has an input coupled to the input path for receiving a control vector 
associated with the cryptographic key and an input connected to the 
cryptographic instruction storage, for receiving control signals to 
initiate checking that the control vector authorises the key management 
function which is requested by the cryptographic service request. The 
control vector checking unit has an authorisation output connected to 
an input of the cryptographic processing means, for signalling that the 
key management function is authorised, the receipt of which by the 
cryptographic processing unit initiates the performance of the requested 
key management function with the cryptographic key. The invention enables 
the flexible control of many cryptographic key management functions in 
the generation, distribution and use of cryptographic keys, while 
maintaining a high security standard.

Title: A low pressure gas discharge lamp
IPC: H01J61/34
Filed: 1989-03-02
Abstract: By enveloping a gas discharge lamp, such as a fluorescent tube (2), in an outer glass tube (8), the discharge chamber of the fluorescent tube (2) is thermally insulated. This enables a sufficiently high temperature to be maintained in the fluorescent tube (2) for, e.g., mercury in the discharge chamber to be brought to a partial pressure at which good illuminating efficiency is obtained even at very low ambient temperatures around the lamp. The tubular envelope (8) is fixated at its ends to the fluorescent tube (2), in some suitable manner such as to surround the fluorescent tube and define a tubular space (10) of constant uniform width between the fluorescent tube and the surrounding envelope. In order to provide a lamp which will ignite readily, the occurrence of space charges between the fluorescent tube (2) and the outer tube (8) has been eliminated, by the provision of siloxane seals (11) between the inner fluorescent tube and the tubular envelope, at the respective ends thereof.

maintaining the ends of the fibers perpendicular to the 
fiber axes. The channel electron multiplier assembly 
(94) is within a vacuum envelope (104) and the photodiode

Title: Machine and method for embossing delicate webs
IPC: B29C59/04
Filed: 1990-06-29
Abstract: Delicate webs of a motif are to be embossed in a sheet of film (1) at a predetermined motif interval by means of a rotating embossing cylinder (7). The embossing cylinder (7) rolls off on a back pressure cylinder (8) and has a recess (10) for attaching the embossing stencil (12). With each revolution of the embossing cylinder (7), a gap (14) is produced relative to the back pressure cylinder (8) during a free phase, which gap is used for a relative movement between the sheet of film (1) and the embossing stencil (12). A control device (24) produces the relative movement with an adjustable amplitude which is predetermined by the motif interval on the sheet of film (1). This relative movement allows embossing at the predetermined motif interval on the sheet of film (1) irrespective of the diameter of the embossing cylinder (7). The usable length of the embossing stencil (12) is more than 50% of the circumference of the embossing cylinder (7).

Title: Method and apparatus for digitally processing a high definition television augmentation signal
IPC: H04N7/30
Filed: 1990-05-30
Abstract: A method and apparatus for digital encoding 
are described for compressing the augmentation channel 
signals (chrominance and luminance signals for panel 
information and high frequency luminance and line 
sifference signal) so that this information can be 
transmitted in a 3 MHz wide RF channel using a digital 
transmission scheme such as QPSK. Analog signal components 
are sampled and converted to digital signals. Each of 
the signals is fed into a separate coder which reduces 
the number of bits/pixel required to reconstruct the 
original signal. Compression is achieved by quantization 
and removal of redundancy. The compression scheme is 
based on the use of DCT together with VLC. Each augmen­
tation signal has its own coder, which is adapted to the 
unique statistics of this signal.

Title: Method of making a compound semiconductor device.
Inventor: TSANG WON-TIEN
IPC: H01L21/28
Filed: 1994-03-23
Abstract: In a preferred embodiment, the disclosed method of making a compound semiconductor (e.g., InP, GaAs) device comprises etching of a semiconductor body by exposure of the body to a chemical beam or beams that comprise an etching medium (e.g., PCl3,AsCl3) and a precursor chemical (e.g., trimethylindium, trimethylgallium), followed by chemical beam epitaxy (CBE) growth of semiconductor material on the etched surface without exposure of the semiconductor body to the ambient atmosphere. Presence of the precursor chemical in the etching beam can result in significantly improved surface morphology, with attendant high quality re-growth. Multiple etching/growth sequences are facilitated by the almost instantaneous (e.g., about 1s) switching between the etching and growth modes that is possible in a reactor according to the invention. <IMAGE>
