Title: Resonant stator balancing of free piston Stirling machine
Inventor: BERCHOWITZ DAVID M
IPC: F02G1/043
Filed: 2008-08-04
Abstract: A linear free-piston Stirling cycle machine has a linear alternator or linear motor with its stator 230 mounted on a spring 250 to provide an improved vibration balancing system. The spring 250 attaches the stator 230 to the interior of the casing 238 to provide an oscillating system permitting the stator 230 to reciprocate and flex the spring 250 during operation of the Stirling machine. The natural frequency of the stator 230 is maintained essentially equal to the operating frequency. For applications in which variations of the average temperature and/or the average pressure of the working gas cause substantial variations of the piston resonant frequency, means for compensating for those changes by varying the stator spring characteristics are also disclosed.

Title: Method and apparatus for minimizing the effect of baseline depression in ionizing radiation measuring equipment
Inventor: PROCTOR ALAN
IPC: G01D3/032
Filed: 2007-06-07
Abstract: Methods and an apparatus for reducing the effect of background ionizing radiation depression in vehicle and container monitoring systems due to shielding effects from components of the vehicle or container or modifications thereof. The methods utilize measurements of background radiation in two spectral regions of interest to calculate a normalization constant, and then utilize the normalization constant to normalize measurements in the same regions of interest when a vehicle or container is tested for the presence of a relevant ionizing radiation source such as 137Cs and 76Ga. Subtracting the two measurements to calculate a net difference provides a substantially valid measure of radiation counts in one spectral region of interest. Preferably the regions of interest abut or overlap, and preferably the spectral widths of the regions of interest are selected so that the attenuation of radiation counts due to background shielding effects in the two regions of interest is substantially equal.

Title: An improved internal combustion engine
IPC: F02B5/02
Filed: 1943-06-25
Abstract: 567,922. Multi-cylinder four-stroke engines. KNIGHT, M. G. E. June 25, 1943, No. 10300. Convention date, May 25, 1942. [Classes 7 (ii) and 7 (iv)] An internal - combustion engine suitable for running either on ordinary fuels or on powdered .fuel, such as nitrated sugar dust, has intercommunicating cylinders A ... D, Fig. 5, arranged in a square with alternate cylinders inverted so that a fuel charge compressed in one cylinder is fired by the flame of the explosion stroke in an adjoining cylinder. The cylinders B and D are connected. to a lower crank-shaft 56, while the inverted cylinders A and C are connected to an upper crank-shaft 55. The flame from cylinder A fires the charge in cylinder B which fires the cylinder C, and so on continuously. The engine may be started by spark ignition. Two adjacent cylinders may be arranged as in Fig. 1. The inverted cylinder 2 having the usual inlet and exhaust poppet valves 6 is separated from its adjacent upright cylinder 9 by ports 7 leading to transfer chamber 14 from which, through a spring-controlled cam-operated poppet valve 15, the flame can pass, when the ports 7 are uncovered by the piston 3, to the compression space 11 of the cylinder 9, thus igniting the compressed charge in this cylinder. An adjustable piston valve 17 controls the size of port 7 and the time of passage of the ignition flame, withdrawal of the piston valve giving the effect of advancing the ignition and vice versa. The exhaust valve 6 of cylinder 2 is not opened until after a valve 15 is opened, the latter valve being closed in time to prevent back flash into the chamber 14. In a similar way, the flame is passed from cylinder 9 to the next adjacent cylinder. In a modification, Fig. 2, a transfer passage 25 is provided between adjacent cylinders, the passage being controlled by sleeve valves. Thus, the cylinder 19 has a ported sleeve 23 and a transfer cut-off sleeve 24 ; other cylinders being similar. In this case, the flame passes from cylinder 19 to cylinder 27. In another modification, ports of the type shown in Fig. 1 may lead to an automatic poppet valve controlling a passage leading into the adjacent cylinder. In this form, the cylinder heads may be filled with adjustable pistons in order to adjust the volumes of the compression spaces. In some cases, the inlet valve for fuel is dispensed with and an injection nozzle provided in the cylinder head to permit the use of pressure-fed fuels.
