Abstract: 1290635 Centrifugal pumps RED JACKET MFG CO 27 May 1971 [15 June 1970] 17578/71 Heading F1C In a multi-stage diffuser-type centrifugal pump, each stage has an annular rubber member and an annular stainless steel member in sealing engagement with each other to reduce backflow of liquid and to provide a radial bearing, one of the members being mounted rearwardly of the rear impeller wall for rotation with the drive-shaft and impeller, and the other member being mounted on a non-rotatable diffuser wall. Fig. 8 shows one arrangement in which each stage has a stainless steel journal 102 mounted either directly on the shaft 22 or, as shown, on an extension 38α of the impeller hub 38 and co-operating with a rubber bushing 103 mounted on a diffuser wall 56. The bushing 103 acts as a radial bearing and as a seal, and is tapered as shown to dislodge sand or grit coming between the bushing and the journal. The members 102, 103 may be transposed, and the member 103 may be straight instead of being tapered. Each impeller 28 may be of plastics material, the front wall 42 being a separate moulding attached to the main moulding by pegs 46 engaging holes 48, the two mouldings being held together by the fluid-pressure conditions. Instead of abutting each other as shown, the impellers 28 may be spaced apart so that they are free to float axially into a state of hydraulic balance. A thrust washer (82), Fig. 2 (not shown), is then provided on the impeller front wall (42) to co-operate with a stainless steel wear ring (78) carried by a diffuser wall (54).

Filed: 1999-02-16
Abstract: The invention is a temporary or emergency lighting system constituted by a bearing structure (2) made of flexible plastic material and having one or more light sources (4) at its top and a support base (1) at its bottom. The structure, which is kept constantly inflated by means of a fan (6), is constituted by one or more superimposed cylinders or cones that are internally divided in sections (2, 1) in order to ensure the progressive and vertical inflation of the structure. The structure can be folded in order to reduce the dimensions of the system as much as possible when it is closed and to make it possible to carry it on the shoulders. The light source is fixed or provided with a rotary mirror (8), in such a way as to direct or rotate the light beam. Some cords or tensioning elements (3) are provided on the structure to limit the height of the bearing structure. The power supply to fans, various functions and/or light source can be guaranteed through a current generator, the power mains or batteries.

Patent IL-129047-A (IL)
Title: Method for packaging articles in an elastic packaging material and device to carry out said method
IPC: B65B47/10
Filed: 1997-09-26
Abstract: The method relates to a method for packing articles and/or objects. Articles are packed in an elastic packing material (2) and the elastic packing material is stretched during the packing process. To achieve this, the packing material is arranged in a receptacle (1) in which a partial vacuum is produced. The packing material is stretched due to the pressure that the outside air exerts upon it. The item that is to be packed is then placed in or on the packing material. Once the vacuum has been removed the packing material automatically reverts back to its original position by virtue of its own elasticity and is applied to the packing items. The invention also relates to a device to carry out such a method.

Title: Assay using marked microbial host cell strains
IPC: C12Q1/02
Filed: 1997-10-10
Abstract: Presence of a contaminating microbial host cell (A), in a culture vessel containing a different host cell (B) able to use more than one carbohydrate (I), is detected by: (a) culturing (B), which includes nucleic acid encoding a particular polypeptide (II) and genetically marked so that it can not use a selected (I), (Ia), as substrate; (b) plating an isolated sample of the culture on a medium supplemented by (Ia); (c) incubating the plated cells, and (d) detecting if any colonies grow in the (Ia)-containing medium. Optionally (A) that grow in the supplemented medium may be plated on a field of different (I) to identify them from their specific (I)-utilising characteristics. The cells are yeasts or prokaryotes, particularly Gram-negative bacteria and specifically E. coli. They express an exogenous (II) and utilise e.g. maltose, ribose or rhamnose. (B) is genetically marked by making (a) a non-reversing, non-suppressing alteration in its genotype, in which case the sample is not diluted before plating or (b) a genotypic alteration that results in a carbohydrate utilisation revertant or suppressant, in which case the sample is serially diluted before plating. Optionally the strain is doubly marked by altering two (I)-utilisation pathways; (i) one type (a), in ribose utilisation and the other a reverting or suppressing mutation in rhamnose utilisation or (ii) both type (a), in maltose and ribose utilisation. Where two alterations are present, two plates are used in step (b), each supplemented with different (I). The vessel is a fermentor containing, before dilution, 108-1011 colony-forming units (cfu)/ml.

Abstract: An in vitro method of identifying or isolating fetal cells from a blood sample is described. Fetal nucleated erythrocytes or erythroblasts are identified by using an antibody or antibody fragment specific for embryonic hemoglobin or an embryonic hemoglobin chain.
