Abstract: A miniaturized delay element was developed for use in medium-and large caliber weapon systems and is realized in a metallic cartridge made of a copper-free light metal. By including a metallic combustible, an oxidant consisting of a halogen-containing high polymer, and metallocenes as sensitizers, an extremely compact and reliable delay element can be produced. By including a detonating charge consisting of an initiating explosive and a metallocene as sensitizer, the delay element can be designed for initiation without darting flame, for striker pins, needles, etc. Due to its properties, the pyrotechnical delay element is particularly well suited for use in highly delayed charges and/or for daughter projectiles and/or for self-destruction of munitions. The delay times achieved can be experimentally and reproducibly determined between 1 and about 30 sec.

Title: Single circuit for detecting a frame synchronization pattern and generating control signals
Inventor: KEM HAN
IPC: H04L7/04
Filed: 1991-02-28
Granted: 1999-12-07
Abstract: A single circuit for detecting a synchronization pattern in a serial data stream. Subsequent to detecting the synchronization pattern, the single circuit generates the control signals for converting the serial data to a parallel format and loading the parallel data into a first-in-first-out (FIFO) memory.      The single circuit includes a controller arranged to receive the serial data stream. A counter is connected to the controller. When the counter is detecting the synchronization pattern and the synchronization pattern is being received, the counter is incremented. Absent the synchronization pattern being received, the counter is reset to a predetermined starting point. Subsequent to detecting the synchronization pattern, the counter generates a load signal.      The single circuit further includes a pulse generator arranged to receive the load signal from the counter and generate a pulse of duration equal to a bit period of the serial data stream. An indicator is provided which generates an in-synch signal after the counter detects the synchronization pattern.

Title: Assay tray and assembly
Inventor: BOJANIC DEJAN
IPC: B01L3/00
Filed: 1991-04-18
Granted: 1995-07-18
Abstract: An assay tray assembly and an assay tray primarily for chromatographic analysis has a plastics moulded test tray 1 mounted on a plastics moulded collection tray 72.   The test tray has a spaced array of chambers 3 disposed as per a microtiter plate.   Each chamber has a bottom outlet port 5 formed by a flange 8 which retains within the chamber a chromatographic medium to which test liquid deposited in the chamber is to be subjected for the percolate or eluate liquid to emerge from the respective outlet ports.   The collection tray 72 has a spaced array of wells 16 disposed as per a microtiter plate to correspond with the chambers 3 and the tray 1 is mounted on the tray 72 for each chamber to communicate with a corresponding well 16.   Each chamber 3 has a tubular spigot part 12 which extends into the respective well 16 to alleviate cross contamination of the liquid derived from the outlet ports 5.   The depth of entry of the tubular spigots 12 into their respective wells 16 is restricted by abutment between the bottom of the test tray with the top of the collection tray.   The volume of each well 16 beneath the tubular spigot it receives is adequate to accommodate all of the eluate or percolate derived from the chamber 3 with which it communicates to alleviate liquid on the spigot parts from dripping into wells with which those tubular spigots are not associated (and thereby cause cross contamination) when the trays are separated for analysis of the percolate or eluate.

Title: Tongue and groove board product
Inventor: CHASE PETER D
IPC: E04F15/04
Filed: 1991-10-18
Granted: 1995-02-28
Abstract: The invention is directed to a tongue and groove product which comprises a first and second major surface and a first and second longitudinal edge.  The first longi-tudinal  edge includes means defining a  longitudinally-extending groove.  The second longitudinal edge includes a longitudinally-extending  protruding  tongue  for  inter-lockingly engaging a complimentary grooved longitudinal edge of an adjacent tongue and groove board.  The protrud-ing  tongue  has  an  upper  and  a  lower  longitudinally-extending  surface.    The major design  feature  of  this invention is that the protruding tongue has at least one substantially vertically-extending opening formed herein. Each of  these  openings extends through the protruding tongue from said longitudinally-extending upper surface to said longitudinally-extending lower surface for providing at least one drain path for water to drain by gravity from said  first major  surface downwardly through each  said vertically-extending opening.  This prevents an accumula-tion of water on the tongue and groove board.   In the preferred case,  the  opening  in  the  protruding  tongue comprises a substantial vertically-extending notch.

Title: Mechanical system for control of a free floating dock
Inventor: CHAPMAN HAROLD S
IPC: E02B3/06
Filed: 1992-02-25
Granted: 1996-08-27
Abstract: A device for maintaining docks or other floating bodies at a given distance from and orientation to the shore by means of a ratchet assembly hinged on the side of the dock closest to shore, and a line attached to two guides, such as pulleys, on the underside of the dock.  When the level of the water varies, the device maintains the dock at the same distance from the new waterline as it was from the old, in the following manner:  the line is anchored at one end on shore and at the other to a bottom anchor beyond the farthest point the dock will extend to at lowest water level.  Tension in the line pushes the dock towards the shore until the ratchet contacts the bottom, where equilibrium is established.  If the water falls, the ratchet pushes the dock away from shore and a new equilibrium is established, farther out; this repeats as long as the water falls.  If the level rises, the ratchet is raised off the bottom and the dock moves towards shore to a new equilibrium point.          This continues as long as the water rises.  Guides are configured so as to minimize rotational movement.

Title: Hinge-lid pack, especially for cigarettes
Inventor: FOCKE HEINZ
IPC: B65D5/66
Filed: 1992-03-20
Granted: 2003-04-29
Abstract: In hinge-lid packs comprising a pack part (12) and a lid (13) hinged to a pack rear panel (15) it is difficult to ensure a precise closed position of the lid (13). This is particularly the case in hinge-lid packs with rounded long-itudinal edges (10,11). To create an additional closing force, outwardly directed deformations, particularly con-vexities (38), are formed in the free portion of collar side panels (28,29) of a collar (26). These convexites abut the inner sides of the lid side panels (17) with an increased friction and thus create an increased closing force. The deformation of the collar side panels (28,29) is a result of longitudinal collar edges (30,31) diverging towards the free edge. As a result, there is a strain of material which effects the deformation of the collar side panels (28,29). A further or alternative closing aid is provided in the form of an upright or inclined cut (39) arranged in the region of the collar side panels (28,29).      As a result of the convexity (38), this cut (39) forms a projecting retaining edge which also abuts the inner side of the pack side panels (28,29) and creates an increased closing force. Moreover, the pack or the blank has a special design, such that rounded contours at the ends of the blanks fit into one another and can be severed from a piece of material without any wasted.
