Title: Measuring intensity of UV light emitted from source - using gas=filled photocell operated with pulsed voltage in self-sustaining glow discharge region and determining ratio of mean discharge pulse duration to trigger pulse duration
Inventor: KUNKEL MARTIN DIPL ING
IPC: G01J1/42
Filed: 1991-06-14
Abstract: A gas-filled photocell, on which the radiation is incident, is operated with pulsed voltage in the self-sustaining glow discharge region. The voltage produces a periodic trigger pulse duration, during which the applied voltage is greater than or equal to the ignition voltage. Discharge voltages are thus produced when a photoelectric emission occurs as a result of photons arriving at the photocathode. The ratio of the average discharge pulse duration to the trigger pulse duration is determined as an indicator of radiation intensity. This ratio is less than 1. USE - Suitable for disinfecting system to ensure that disinfection is actually carried out over defined area.

Title: Computer simulation technique - to determine gamma ray detection probability in an emitter detector system
Inventor: HAASE GERHARD DR
IPC: G01T1/29
Filed: 1991-12-06
Abstract: A means for determining the total detection probability of a gamma-ray emitter/detector system performed using a computer simulation. For the simulation the following parameters are user defined. 1) The emitter volume from which the photons are emitted (e.g. height (H) and radius r' of a cylindrical source). 2) The detector volume (e.g. radius (r) and height (h) for a cylindrical detector). With the above parameters set, the emission point is generated randomly, or is the solid angle of the emitted photon. The photon path length is then calculated from a large number of different emission points and angles the detection probability is determined. USE/ADVANTAGE - Determination of the detection probability means that correction factors for the summation and (self) absorption effects can be determined. Summation takes place when two photons are incident simultaneously on the detector (in which case they are treated as one high energy photon) and absorption refers to photons being absorbed or slowed down within the emitter volume rather than the detector. Absorption and summation effects are geometry dependent. The claimed method avoids their laborious experimental determination as they may be determined using commerically available personal computers within seconds.

Title: Spring-type safety holder for fixing guitars to walls - has spring peg and lined block securing instruments against damage
IPC: G10G5/00
Filed: 1991-12-16
Abstract: An oblong spring part forming part of a peg-like removable element is clamped or screwed onto the guitar pointing in the direction of the axis of symmetry of the instrument. This spring part is to be hung in the associated groove of the felt-lined hanging block (7). The groove is formed from an upper thin vertical milled part, a wider horizontal milled part whose minimum width equals the max. length of the spring, and a lower thinner vertical milled part with all the milled parts connected together to form an S-shape so that when the guitar is hung up by its spring peg it is securely fixed in practically all directions and prevented from slipping out. An angled ceiling holder can be used to fix the guitar from the ceiling. USE/ADVANTAGE - The holders require a certain movement with simultaneous application of force to insert and remove the guitar, which acts as a safety measure.
