Title: Measuring beat frequency variations between two single mode lasers for distance measurement - sweeping wavelength of at least one laser and measuring and evaluating resulting phase angle change
IPC: G01B9/02
Filed: 1991-12-03
Abstract: The method involves influencing the frequencies of the lasers using acoustic optical modulators to operate a superheterodyne interferometer whose periodic output signal's phase depends on the reflector distance and beat frequency. The wavelength of at least one laser is tuned monotonically over a defined range to cause a monotonic change in beat frequency. The resulting phase angle variations and the total phase change are recorded. The beat frequency change is obtained using a simple algorithm taking account of signal propagation speed. An absolute distance measurement is obtained using two interferometers. USE/ADVANTAGE - For exact measurement of beat frequency of two single mode lasers and high resolution distance measurement.

Title: Water hardness and pH long term control e.g. in ponds, fish tanks etc. - by circulating part of water through ion exchange unit for reduced mineral content and volume of water circulated is regulated in relation to pH value
Inventor: WINKLER HARALD
IPC: B01J47/15
Filed: 1992-02-17
Abstract: In a new procedure for regulating the hardness and pH of water, a pH meter controls a water circuit containing an ion-exchange unit which greatly reduces the salt content of the circulated water before returning it to the main body of water.

Title: Czochralski single crystalline silicon@ growth - gives improved yield of defect-free bars due to optimisation of particle distribution, roughness, fracture and pull strength of the polycrystalline grains continuously added
Inventor: OHMURA MASANORI
IPC: C30B15/02
Filed: 1992-03-11
Abstract: Si single crystals are grown using a Czochralski method with continuous resupply of granular polycrystalline Si. Granular material properties are optimised as follows: average surface roughness is not more than 0.5 micron, obtd. by cleaning of the granules, pref. using a watery HF soln., the number of granules with a dia. of 2 mm or more is not more than 1000 per 1 kg of material; the average ratio of cavity area to grain area is not more than 3%; the fracture strength KIC is not less than 1.5; the pull strength is not less than 15 kg/mm2; the polysilicon is pref. made by thermal decompsn. of silane or trichlorosilane in a fluid bed reactor. USE/ADVANTAGE - The optimisation of the granular material reduces the number of fracture pieces formed and thereby increases the yield of single crystalline bars without defects. Analysis has shown that fracture occurs due to the thermal shock and that the number of pieces formed depends on size and strength of the grains and number of potential fracture sites. The method is used in the growth of Si crystals, esp. for large, e.g. larger than 6 inch dia., bars.

Title: Shuttleless loom - has leno selvedge former to twist warp threads interweaving with the weft fringe
Inventor: MARX ALFRED
IPC: D03C7/06
Filed: 1993-01-21
Abstract: Equipment to form leno selvedge is attached to the heald frames so that the two threads from a twisted shed, into which the fringe of weft is engaged. The slides of the former are spring held in frame which carry each thread first to one side and then the other. The slides are made from abrasion resisting material. Pref. the leno selvedge former is an assembly of parts. Frame encloses the sldie. The slide has two slots which cover similar slots in the carriage, but at opposing angles. The slots are ceramic to resist wear from a thread which passes through. The thread passes through in th manner of a warp, so that as one is lifted, the other is lowered, and in addition, guided by the angle of the slots, they cross over each other. This means that as the weft fringe created by a shuttleless loom is trapped in the shed, the selvedge warp thread is twisted as it interweaves. ADVANTAGE - The method of springing is good and the parts will withstand considerable movement at speed before needing to be replaced.
