Abstract: TITLE OF THE INVENTION       CERAMIC MATERIAL AND METHOD OF MANUFACTURE     ABSTRACT OF THE DISCLOSURE    A dual phase silicon aluminum oxynitride material comprising a first phase Si-Al-O-N, commonly referred to as .beta.-Si-Al-O-N, and a second phase Si-Al-O-N referred to as .alpha.-Si-Al-O-N.  In addition to the double phase Si-Al-O-Ns, there is usually included a glassy type material which can formulate up to ten percent by weight of the total composition.  The material may be manufac-toward by forming a polytype material made from reacted alumina, aluminum nitride and silicon nitride.  The poly-type material may be mixed with further powders of sili-con nitride and an oxide of yttrium, lithium or calcium and finally reacted to a double phase Si-Al-O-N material where hardness is increased with the additional .alpha.-Si-Al-O-N without significantly affecting its strength.    The material may be formed in situ by mixing alumi-num nitride, alumina, silicon nitride, together with an oxide of yttrium, lithium or calcium.  These materials can then be sintered to a final product containing a double phase Si-Al-O-N.  Control of the alumina content in the polytype or in situ methods affects the percent-age of .alpha.-Si-Al-O-N produced in the final product.  The hardness of the material increases with the .alpha.-Si-Al-O-N     content without significantly affecting its transverse rupture strength.

Abstract: ABSTRACT OF THE DISCLOSURE            A security installation comprises sensors arranged in and around a building which transmit digital information to a central station by radio, in each case preceded by an access code specific to the particular installation; signals inadvertently received from the sensors of an adjacent installation are rejected.          The information is transmitted by encoding a multiple bit word incorporating the access code, a code identifying the particular sensor, and the actual data, using Manchester II coding on an FSK transmission.          Each such word is sent several times to form a data packet.  The master station tests the received data for the correct format and for the correct access code.  Recognition is only complete when within a particular packet, at least two (say) sequential words and at least two other words are recognised.

Abstract: Abstract Magnetic Lock Insert for Lock Mechanisms The invention concerns a cylinder lock actuatable by means of magnetic bodies, which may be a single lock insert connected to the bolt carrier of the lock mechanism ,  or a lock consisting of two axially-symmetrically lock bodies surrounding the bolt carrier from two sides, the insert including an internal cylinder rotatable by a magnetic key between an open and a locked position.  Latches in latch grooves formed at both sides of the cylinder are turnable together with the cylinder in the lock body.  A line or series of rotors is arranged in respective notches of the rotor supports.  The rotors are turnably journalled on shafts and have latch-receiving channels.  In their wedged position, the latches prevent turning of the cylinder with a foreign object.  The rotor supports and the rotor housing are recessed into the opposite sides of the cylinder surface.  The cylinder has a locating pin provided with a catch or a steel ball for fixing the turnability of the lock body and the removal position of a proper key.  The cylinder has bores into which tumblers of varying lengths for preventing cylinder rotation, the effective length of the tumblers being set by the steps of the key bit.     Two control rings (29a, 29b) are arranged between the cylinder (2) and lock body (1) which are provided with latch grooves (9) receiving that part of the latch (8) which prevents cylinder (2) rotating.  The rotor housing has a latch channel (11) formed along the chord of the magnetic body (5) in the rotor (6) and can receive the other part of the latch (8) in a state of magnetic equilibrium determined by the magnets in the key (3) and the magnetic body (5).  When a proper key (3) is fitted into the keyhole (10), the latch channel (11) is arranged partly in the rotor (6) housing and partly in the rotor support (4):  in this position the cylinder is freely rotatable.  When the proper key (3) is removed, the latch channel (11) in the rotor housing is outside the line of action of the latch (8), the latch (8) being arranged in the rotor support (4) and in the latch grooves (9) of the control rings (29a, 29b).          The latch groove (33) assuring the locking position of the latches (8) is formed in the lock body (1) along the line of the latch grooves (9) of the control rings (29a, 29b).    In a preferred embodiment, a shoulder formed on the side of a two-part lock bolt carrier (15a, 15b) fits into the groove formed on the end of cylinder (2), which shoulder surrounds the end of the cylinder (2).    In another preferred embodiment, any of the two latch channels (100, 102, or 100, 103, or 100, 104, etc.) may form the latch channel of an individual or master or general key system, and a selection of the angular position between the latch channels (100, 102, or 100, 103, or 100, 104, etc.) and the relative positions of the instantaneous, variable magnetic fields represent the variation factors of the key or lock systems, the locking number of which rungs into the range of several millions.
