Abstract: The present invention provides a vacuum cleaner comprising a body housing an electric powered blower, a dust case being connected to and free to be detached from the body, a lid having an intake and being fitted to the dust case, which lid is free to be opened and closed, a bag-shaped filter being freely fitted to and removable from the inner surface of the lid and communicating with the intake, and a dust dumping aperture provided in the dust case and accessible by pivoting away a filter housing unit, the dust dumping aperture being used to remove the bag-shaped filter from the dust case.

Abstract: Salt bridge liquid for use in potentiometric measurement of blood or a blood liquid.The salt bridge liquid contains Na.sup.+ -ions and HCOO.sup.- -ions in substantially equimolar amounts, preferably in a concentration larger than or equal to 1 M, in particular about 4 M.When this salt bridge liquid is used, the potentiometric measurement will give corresponding results when measuring a blood sample and the corresponding plasma sample because the suspension effect which is caused by the erythrocytes and which is seen when using other salt bridge liquids is substantially eliminated. Furthermore, different blood samples with the same ion concentration but with varying erythrocyte content will give corresponding measuring results.

Abstract: A gel preparation for external application by being prepared from diclofenac sodium as the active ingredient, water, lower alkanols and glycols as medium, a carboxyvinyl polymer as gelating agent, a weak basic substances and optionally adding peppermint oil, l-menthol or salicylic acid ester as auxiliary agent.

Abstract: A process for treating sand which includes one or more stages in which sand is mixed with a dilute aqueous solution of hydrofluoric or sulphuric acid together with zinc or sodium hydrosulphite and the resulting slurry is agitated at ambient temperature in an atmospheric oxygen-free environment.

Abstract: In accordance with the principles for transcutaneous measurement of a blood parameter, such as the partial pressure of a blood gas, an electrochemical measuring electrode device (1) is applied to the skin surface (2) of a person. The electrode device has a body (10), e.g. a thick film substrate, which is thermostated to a predetermined temperature and, furthermore, includes a sensor (11) together with a membrane (14) confining an electrolyte solution within an electrolyte reservoir (15). Furthermore, the electrode device includes a jacket having an annular metallic body (16), a metallic body (4) and a thick film substrate (8), which is thermostated to the same temperature as the body (10) of the electrode device.

Abstract: A foldable knife (10) comprises a handle (14), a blade (12), means (24) for securing the blade (12) to the handle for pivotal movement between a closed position wherein the cutting edge (20) is received in a recess (34) in the handle (14) and an open position wherein the cutting edge edge (20) is exposed, a bar spring (16) secured at one end to the handle (14) in the recess (34), and a mechanism (18) secured in an opening (58), (60) in the handle (14) and extending through a hole (44) in the bar spring (16), the mechanism (18) comprising an enlarged portion (48) and a reduced portion (b 50), and means (54) for moving the mechanism (18) between a locking position when the enlarged portion is in the hole (44) for limiting movement of the bar spring (16) for preventing movement of the blade (12) and a release position wherein the reduced portion (50) is in the hole (44) and sufficient movement of the bar spring (16) is accommodated for moving the blade (12) to the closed or opened positions.

Abstract: A rubber roller for spinning whose rubber cot comprises an inner and an outer rubber layer bonded together over a reinforcing layer consisting of a woven cloth or sheeting and fitted securely on the outer periphery of a metal core for roller, without using an adhesive and the manufacturing method thereof.
