Title: Albumin recovery from blood fractions - by first treating with an anionic ion exchanger, then selective denaturation of other proteins
IPC: C07K14/765
Filed: 1975-08-26
Abstract: Prepn. of blood albumin (I) comprises first sepg. a (I)-contg. fraction from blood protein, serum or plasma by treatment with a anionic ion-exchange resin having amino, alkylamino, guanidino or quat. ammonium exchanging gps. An aq. soln. of this separated fraction is prepd., an agent (II) capable of stabilising (I) against heat-denaturation is added, then the soln. heated to denature proteins other than (I). The denaturated proteins are removed leaving a soln. of (I). The stabiliser is >=1 of acetyltryptophan; middle chainlength fatty acids or the salts of these cpds. (esp. Na octanoate). Pref. the resin is crosslinked regenerated cellulose or crosslinked dextran contg. diethylaminoethyl gps. I) is used as a plasma-volume extender and to treat hypoproteinaemia. Using the ion exchange treatment gives a more conc. (I) fraction almost completely free of gamma-globulins (which tend to resist the heat-denaturation step), so less unwanted protein has to be removed.

Title: Horizontal sliding window frame guide strip - is of extruded plastic with ribs in grooves to grip frame
IPC: E06B3/46
Filed: 1975-09-04
Abstract: The strip is for fixing to the threshold of the frame of a sliding frame assembly, there being two or more frame sections sliding horizontally in the grooves of it. It is of extruded plastic, each of the grooves (39-42) running horizontally when installed. Convex ribs (43) are formed in the base of each groove, to grip the respective frame. A profiled flange (37) can be provided on the strip, clear of the grooves, for insertion in a groove in the frame threshold, so as to hold the strip in position. The design prevents the frame sections sliding too easily in the strip, while reducing the hindrance to them doing so due to accumulated dirt.

Title: Floor covering with embedded electrical conductors - forming high frequency resonance circuit for use as warning signalling device
IPC: G08B13/10
Filed: 1975-09-12
Abstract: A floor covering contains electrically conductive threads or wires, each of which extends over a considerable length of the fabric. Each thread along one of the edges of the floor covering is arranged so that a signalling device can be connected to it, and the conductors in separate lengths can also be attached continuously. The conductive threads, together or separately may form part of a high frequency resonance circuit, the capacity of which alters when a body comes into its proximity. There are no contacts to be closed, and any breakage of the threads is signalled immediately. The carpeting can be fitted in banks, museums, in halls and doorways, etc. so that the approach of any individual can be signalled immediately. The conductive threads, wires, strips, etc. may be woven into the carpet, so that they cannot be removed from it.

Title: Process for controlling and guaranteeing the safe (secure) operation of heating appliances (heaters) not connected to the chimney, especially oil-based heating appliances, and device for implementing the process
Inventor: BEMMEL JAN VAN
IPC: F23N5/24
Filed: 1991-04-19
Abstract: The invention relates to a process and to the device for controlling and guaranteeing safe operation of heating appliances not connected to a chimney and especially oil- based heaters indoors, under both normal conditions and conditions falling outside the latter. Outside the normal conditions of normal heating there is the danger of incomplete combustion occurring, with the consequent reduced levels of O2 and increased levels of CO2 in the indoor air. The objective of the invention is to enable the level of CO2 in the indoor air to be controlled rapidly and precisely and to guarantee, independently of the intensity of the flame of the burner, that the oil- based heater can be adjusted and safe operation thereby guaranteed, independently of the detection of the intensity of the flame sensitive to radiation. In accordance with the present invention, the said objective is achieved by measuring the level of O2 in the combustion gases of the burner inside the oil-based heater sensitively and using this value as a measurement for controlling the level of CO2 in the indoor air and converting a tension (voltage) signal to be used as control signal, in which, during operation of the burner outside a preset range of intensity of flame, use is made of the said O2-sensitive detector both for reestablishing a normal heating condition and for regulating operation at a minimum flame intensity and the production of an alarm signal and automatic delayed snuffing-out of the burner which take place at a first and at a second predetermined level of O2 in the combustion gas of the burner, respectively, corresponding to predetermined levels of CO2 in the indoor air, the second level being lower than the said first level. In addition, means are installed for detecting, sensitively, the level of CO in the combustion gas of the burner inside the oil-based heater and also for using the said level as a measure for adjusting the level of CO2 in the indoor air, after conversion into a corresponding control signal.
