Title: Sodium silicate soln. mfr. - by reacting sand and sodium hydroxide soln. at elevated temp. and press. in a tubular reactor
IPC: C01B33/32
Filed: 1978-03-13
Abstract: Na silicate solns. are made by reacting sand with caustic soda soln. at >=200 degrees C and elevated press. in a tubular reactor of the type known for decomposing bauxite. Pref. the ratio SiO2:Na2O is 2:1 to 2:1:1 and the temp. is 240-280 degrees C, or the ratio SiO2:Na2O is 1.0:1 to 1.1:1 and the temp. is 200-240 degrees C. The strength of the NaOH soln. is pref. chosen such that the resulting soln. has a solids content of 35-57%. Using reactors of the type used for decomposing bauxite with NaOH (see e.g. NL7201115, 7201203 and 7601199) allows temps. of >200 degrees C to be used and avoids the problems and inconvenience encountered when using autoclaves for the reaction. The desired end prod. is produced directly with only a few minutes' residence time in the reactor, and due to the high temps. used, no viscosity problems are encountered in handling water glass solns. with a concn of 35-57% solids. The process can be carried out continuously and automatically with low energy consumption and low investment costs.

Title: Accessory for filling syringe with correct dose - has holder for ampoule and syringe and stop cap to limit expulsion stroke of piston
IPC: A61J1/00
Filed: 1980-11-19
Abstract: The syringe, with piston withdrawn beyond the required dosage, is placed in a tubular holder so that the needle pierces the membrane of the ampoule clamped in one end of the holder whilst the upper end of the syringe is located at the other end of the holder. The piston is then depressed to expel the air and again withdrawn to fill the syringe beyond the required dosage. After this, the piston is again depressed using the accessory of which one face engages the operating end of the piston rod whilst another (annular) face acts as stop when it meets the said upper end, the distance between these faces corresponding with the correct dosage. The accessory enables filling the syringe by feel without reference to the graduations, which is particularly helpful e.g. for diabetics with poor eyesight who have to administer regular injections. It also avoids inaccuracies which may occur when one person has to inject a number of patients, as these may each be issued with their own (pref. adjustable) accessory.

Title: HV appts. for treating psychotic auditory hallucinations - applies HF electric field to membranes of patient's auditory nerve cells
IPC: A61N1/40
Filed: 1988-01-22
Abstract: Capacitive plates are placed near each side of the head of the person suffering from auditory hallucinations. A very high voltage, e.g. several million volts, is modulated at high frequency in accordance with the method developed by J.A. d'Arsonval in 1892. A strong electric field then causes the Stark effect (named after Johannes Stark 1874-1957). The atoms of the receptors in the membrane of the patient's acoustic nerve cells are affected by the field and the absorption wavelength of the atoms is altered. The frequency is tuned until the patient tells the practitioner that the hallucinations are reduced. As a result, the membranes will no longer resonate at the detected psychotic wavelength and the hallucinations will cease.

Title: Method and apparatus for measuring total nuclear magnetic resonance porosity
Inventor: FREEDMAN ROBERT
IPC: G01V11/00
Filed: 1998-04-09
Abstract: A method and apparatus for measuring total nuclear magnetic resonance porosity of an earth formation traversed by a borehole is sensitive to fast relaxation times that can be associated with clay-bound water. The total porosity measurement includes, in addition to free fluid and capillary-bound porosity, the porosity of clay-bound water and microporosity. An oscillating magnetic field is produced within the borehole, according to a phase alternated sequence, such as the Carr-Purcell-Meiboom-Gill (CPMG) sequence or a similar pulse sequence, to induce signals in the volume of formation which are measurable by the NMR logging tool. A reduced echo spacing and improved signal-to-noise ratio allows the recovery of short T 2  components. The spin echo signals are measured and a value is determined for each signal. The signal values are separated into a first set and a second set wherein the first set comprises the early-time echo signals and the second set comprises the remaining echo signals. The second set of echoes are sub-divided into a plurality of groups and a window sum value is generated for each group of the second set, thereby producing a plurality of window sums. An attribute of the formation is determined based upon the plurality of window sums and the value of each signal of the first set.
