Abstract: 1,164,895. Image intensifier tubes; electron multipliers. MULLARD Ltd. 29 March, 1967, No. 14226/67. Heading H1D. In an electronic imaging tube comprising a photo-cathode P spaced by an electron optical system from a channel intensifier device I, the channel intensifier is a secondary emissive electron multiplier device which includes a curved plate with the concave face towards the photo-cathode and with conductive input and output layers E1 and E2 on opposite surfaces and, passing through the plate, a large number of parallel elongated channels, and the electron optical system is such that principal rays, which are the paths of those electrons leaving the photo-cathode at right angles, are brought to a focus in front of the channel intensifier in the focal plane which is also curved and concave towards the photo-cathode. The shape of the input face E1 of the channel intensifier and the focal plane are made similar to obtain uniform resolution. Preferably the channels are uniformly tilted with respect to the common axis of the tube and channel intensifier, as described in Specification 1,164,894, so that the formation of a dark spot is avoided by preventing electrons from being able to pass straight through a channel without undergoing any multiplication. A channel intensifier having spherical surfaces and channels of equal length may be simply fabricated by forming first a flat block with tilted channels therethrough, Fig. 4A (not shown), and subsequently machining the flat surfaces such that they have equal radii with one centre on the tube axis and the other slightly displaced both along the axis and away from it, Fig. 4B (not shown). The imaging tube may be an image intensifier or converter tube with a diode type electron optical system when the conical anode A is connected to the input layer E1, or a triode type if the anode and layer El are unconnected and differently biased. Shaped fibre optic elements (FO 1) and (FO2) may be employed between the object and photo-cathode and as faceplace for the luminescent screen S, which may also be curved, Fig. 5 (not shown).

Title: Method and apparatus for producing foil bags.
Inventor: WILD HANS-PETER
IPC: B31B160/20
Filed: 1999-06-01
Abstract: The method involves transporting two foils (4,6) from which the sides of the bags will be formed. Holes are formed in a base foil (8) at intervals corresponding to the width of a bag while transporting it. The base foil is folded along the center line parallel to the transport direction (52), whereby the holes are arranged symmetrically with respect to the center line. Hole measurements are performed. The side foils and folded base foil are stacked. The foils are joined so that where the base foil is sandwiched between the side foils, the side foils are only joined directly to each other via the holes. The joined layers are cut so that a side edge joint region is divided between each two foil bags. An Independent claim is also included for an arrangement for implementing the method.

Title: Mechanism for supporting wired and wireless methods for client and server side authentication
Inventor: ADUSUMILLI KOTESHWERRAO
IPC: H04L29/08
Filed: 2003-01-10
Granted: 2005-12-21
Abstract: Authentication functions are centralized in a security system to offload servers of this functionality, and to provide an end-to-end solution for secure internet transactions. The security system supports authentication functions for authenticating a server by requesting server certificates from a certificate authority, and sending server certificates to clients requesting authentication. The security system also authenticates clients by checking digital signatures, validating the client certificates, which includes checking CA signatures, checking the validity period of the signatures, maintaining a certificate revocation list (CRL), and checking client certificates against the CRL.
