Patent GB-2060156-A (GB)
Title: A heat exchange fluid-cooling system and apparatus
IPC: F28F1/12
Filed: 1980-09-18
Abstract: A heat exchange system for cooling a fluid to be cooled, such as ammonia or water, has conduits (28) for conducting said fluid in indirect heat relationship to a heat absorbing coolant liquid flowing in other conduits (26). Simultaneously, air is forced or induced by a fan (18) to flow across the conduits (28) to achieve additional cooling of the fluid to be cooled. The heated absorbing liquid is conducted from its associated conduits (26) and dispersed by nozzles (56) into air, before or after the passage of the air across the conduits (28), in accordance with air temperature and heat load conditions to evaporate some of the heat absorbing liquid and thereby effect cooling of the heat absorbing liquid. The cooled heat absorbing liquid is recirculated (e.g. from a reservoir 22) to its associated conduits (26) for cooling additional quantities of fluid to be cooled flowing through its associated conduits (28). <IMAGE>

Filed: 1980-11-03
Abstract: The invention relates to an apparatus for heat treatment of milk, comprising a heat exchanger 1, where the milk is heated to the required high temperature by means of heated water from a water heater 3, and a holding vessel 2 in which the milk is kept during a predetermined period of time. The new feature resides in that a regenerative section (9) in the heat exchanger 1, which includes a heating section (6) and a regenerative section (9), has a space intended to be traversed by incoming, untreated milk, and a space intended to be traversed by heated milk coming from the heating section (6), so that incoming milk is preheated by outgoing milk, that the holding vessel (2) consists of a coil which, as seen in the flow direction, is arranged between the heating section (6) and the regenerative section and has a variable length adjusted to the intended flow and required holding time, and that the apparatus is adapted for immediate connection to a milking plant (M) so that the milk arrives in the apparatus at a substantially maintained milking temperature. <IMAGE>

Patent GB-2071335-A (GB)
Title: Magnetic Proximity Switch
IPC: H03K17/97
Filed: 1981-03-04
Abstract: A magnetic proximity switch is described which produces a non- transient electrical output signal, i.e. an output signal which is maintained as long as a position is held within a predetermined critical distance. The proximity switch employs a bistable magnetic element (1) e.g. a Wiegand wire which is coupled with an electrical winding (3) supplied with an alternating voltage or pulsating direct current, and which produces at the position of the bistable magnetic element (1) a magnetic alternating field which is sufficiently strong to change periodically the magnetisation of the bistable magnetic element (1). The change of magnetisation occurs abruptly and induces in a sensor winding (2) a train of electrical voltage pulses. A magnetic direct field, e.g. the field of a displaceable bar-magnet (4), is superimposed upon the magnetic alternating field. By altering the position of the bar-magnet (4), the resulting magnetic field can be so changed that it is no longer capable of changing the magnetisation of the bistable magnetic element. Thus, there are positions, e.g. of the bar- magnet (4), in which pulses occur in the sensor winding (2) and other positions in which the pulses do not occur in the sensor winding. <IMAGE>

Patent GB-2103627-A (GB)
Title: Transition metal composition
Inventor: KELLAND DR JOHN WILLIAM
IPC: C08F10/00
Filed: 1981-08-07
Abstract: A titanium-containing composition is obtained by forming a magnesium halide-ester material, suspending this material in a liquid medium containing titanium tetrachloride, (preferably undiluted liquid titanium tetrachloride at elevated temperature) separating the solid from the liquid phase, repeating the treatment with titanium tetrachloride, and washing the solid product at least once to give a product in which the titanium level is in the range from 1 up to 5% by weight. The magnesium halide-ester material is conveniently produced by grinding together magnesium halide and an ester, such as magnesium chloride and ethyl benzoate. The titanium-containing composition may be combined with an organic metal compound such as aluminium triethyl and preferably a Lewis Base, particularly an ester such as ethyl benzoate, methyl p-methylbenzoate, or ethyl p-methoxy-benzoate, to give olefin polymerisation catalyst. The particle form of the titanium-containing composition can be improved by including a spray-drying step in the process of producing the composition or by spray- drying the composition when it has been produced.

Title: Metachromatic dye sorption and fluorescent light emissive means for differential determination of developmental stages of neutrophilic granulocytic cells and other leukocytes
Inventor: KASS LAWRENCE
IPC: G01N21/64
Filed: 1983-02-11
Abstract: The selective use of certain basic quaternary, metachromatic dye stains has already made possible instantaneous optical differentiation of the five major individual leukocyte species, and certain specific leukocytes can also be differentiated. This invention involves fluorescent light emission from the dyed specimen to carry out differentiation, identification and enumeration of basic orange - #21-dyed supravital cells. The colors under fluorescent light response are sufficiently dissimilar for there to be no confusion as to identify with white light absorbance results. Both modes of examination of the same sample are used. Using coherent laser light in stimulating the fluorescent mode suggests the application to flow cytometry methods of similar analysis by automatic equipment. The bi-modal light sources offer use of cytological comparisons which reveal details of comparisons and differences not previously recorded. Identified basic reds and violets of the methine and polymethine chromophoric class cause metachromatic staining of monocyte nucleus in absorptive light as well as under metachromatic fluorescence thereby verifying monocyte identification.
