Title: Recoil control mechanism for a weapon
Inventor: RICHARD GIZA
Filed: 2001-09-02
Granted: 2006-06-28
Abstract: A recoil control mechanism for a weapon which fires a projectile which is characterised by the generation of a forward counterforce to the rearward recoil simultaneously with absorption of rearward recoil force upon initiation of propoulsion of the projectile. The forward counterforce is generated by propelling a first mass forwardly upon firing the projectile and substantially simultaneously propelling a second mass rearwardly for absorbing some of the recoil force. In one mechanism (10), the first mass may be the weapon's barrel (12) and the second mass its breach block (14). Expaning gases (36) from detonation of propellant in cartridge (24) enter a reaction volume (28) between the barrel (12) and breech block (14). These gases drive barrel (12) forwardly against force transmission spring (16) to impose a forward counterforce on the weapon's frame (18).; Substantially simultaneously recoil from detonation of cartridge (22) together with the gasses (36) in reaction volume (28) drive breech block (14) rearwardly against force absorbing spring (20).

Title: Nuclear fuel element leak detection system
Inventor: JOHN C JR
IPC: G21C17/06
Filed: 1978-04-29
Granted: 1981-10-25
Abstract: Nuclear fuel elements (30) are tested for leaks as they are removed from a building in which they are made.  An element is loaded through a door into a compartment in the building wall.  The door is closed and the compartment is evacuated.  A particle detector senses any leakage from the element.  If no leakage is detected, the element is discharged through a second door (26).  If leakage is sensed the element is passed back through the first door (24).  The method may be used to test sheathed uranium fuel elements pressurised with helium.

Title: Speed sensor
Inventor: PELAN JAMES J
IPC: G01S13/60
Filed: 1985-05-13
Granted: 1993-03-04
Abstract: The sensor comprises an ultrasonic transmitter and receiver and a processing circuit in which a phase-locked loop tracks the received frequency in order to indicate the speed of a vehicle over the ground. A circuit (18) provides an attenuated and phase-shifted replica of the transmitted signal. This is combined in a circuit (20) with the received signal (14) to cancel out a cross-talk component in the received signal. A low pass filter (26) and squaring circuit (28) provide a signal (30) for the phase locked loop which is substantially pure at the reflected and received signal frequency. It is therefore possible to compare this with a reference frequency corresponding to zero speed to provide an output signal with sign and magnitude indicating respectively the direction (forwards or reverse) and speed of movement of the vehicle.

Abstract: The  DRAM  cell  for  increasing  the  storage  capacity  by parallel-conntecting a trench capacitor and  a  stacked  capacitor comprises  a  transistor  area  having  a   source   region   (53) neighboring to a field oxide film (46) formed on a substrate (40), a drain region (52) spaced from the region (53) through a  channel region and a conductive word  line  (50),  and  a  capacitor.  The capacitor  includes  a  trench  cell  node  layer  (60)  having  a diffusion region formed into the substrate placed under the source region (53), a stacked cell node layer (64) deposit on the  source region (53) and spaced from the word line  (50)  and  field  oxide film (46) by a first insulation film (71), a dielectric film  (58) formed on the inner surface of layer (60) and  the  stacked  layer (64), and a cell plate layer (56) formed on the film (58) so as to fill the inside of the trench.
