Title: Device for determining liquid volumes by measurement of the dilution of a radio-active solution
IPC: G21H5/02
Filed: 1966-03-24
Abstract: A liquid volume e. g. the blood volume of a human being, is measured by determining the dilution of a radio-active solution using a photodetector to measure the activities and thereby concentrations of samples before and after the dilution. In the determination of blood volume, the concentration of a radio-active marker in a solution is measured, the solution injected intravenously, and after a certain time, a blood sample taken and its concentration determined and compared with that of the original injection solution. Since the concentration of radio-active material is directly proportional to the volume it is contained in, the total volume of the vascular system into which the injection was made, may be determined. The invention seeks to provide for the great difference between the concentrations, and thus activities, of the blood sample and the original injection solution, but to avoid having to dilute the injection solution before determining its activity and thereby avoid errors due to radio-active decay before the injection can be carried out. The apparatus used comprises a movable tripod 1, carrying a housing 4 containing the detector system, a photo-multiplier 7 and a hollow, thallium-activated sodium iodide scintillation crystal 6. Lead shielding 10 is formed with a pedestal 14 in which a threaded column 12 turns freely on rotation by a wheel 15, causing a threaded nut 17 to move up or down the column. The nut is integral with a support plate 18 for a syringe 20, allowing the latter to be moved to the required distance from the detector system. The distance of the syringe support from the detector is adjusted so that the activity, measured by the detector, of a syringe full of the injection solution, is of the same order as that which will be recorded when a test tube containing a blood sample taken a certain time after the injection, is placed in the bore of the scintillator crystal 6. To obtain this distance a test tube of solution diluted to a known dilution, say 1 in a 1, 000, is placed in the crystal bore and the activity recorded. The same amount of the concentrated solution in a syringe is then positioned in the support plate 18 and the position changed until the same activity is recorded. A series of measurements may then be carried out without dilution of the injection solution beforehand, a first measurement of the injection solution being carried out with the syringe in the support plate and a second of a blood sample carried in a test tube in the crystal bore. The known ratio is taken into account when the activities are compared to calculate the blood volume.

Title: Self priming system for horizontal pumps
IPC: F04D9/00
Filed: 1967-06-10
Abstract: A self-priming pump 20, Fig. 1, having a horizontal inlet 6 draws liquid from a suction line 40 via a suction well 4 having a cavity which is at least in part below the inlet 6 and is connected at its upper part to the suction line 40. A suction pipe 5 extending from the inlet 6 towards the bottom of the suction well 4 may, as shown, be curved upwardly so that the lower inner surface of the upper portion is approximately level with the upper inner surface of the inlet 6, and an air bleed aperture may be provided in the upper portion. The pump discharge through a discharge column 8 containing a repriming valve assembly 30. During normal flow, the depression occurring at the throat of a Venturi in the lower part of the inner casing 34, Fig. 2, of the assembly 30 and communicated via tubes 35 to cylinders 36, maintains poppet valves 31 closed. If the pump loses its prime, the valves 31 are opened by springs 37 and liquid in the discharge column 8 and assembly 30 returns via the valves 31 and a drain pipe 9 to the suction well 4. The air displaced from the suction well 4 by the returned liquid passes via a pipe 10 and a non-return valve 11 to the discharge column 8 at a point upstream of the main non-return valve 12. When the returned liquid has risen through the suction pipe 5 into the inlet 6, it is passed by the pump 20 into the discharge column 8. The resultant flow through the Venturi within the valve assembly 30 causes the valves 31 to close. The non-return valve 11 closes, and the air which has entered the discharge column 8 is forced through the non-return valve 12 into the discharge line 42. The reduction of pressure in the suction well 4 due to the removal of the liquid from the suction well draws liquid up through the suction line. The cycle repeats until priming is completed. In a modification, Fig. 3 (not shown), a pipe (63) is provided to pass entrapped air from the impeller inlet casing (64) to the suction well (4) or to the upper end of the discharge column (8).

Title: Process of producing microcrystalline lipophilic and hydrophilic ammonium nitrate
IPC: C06B21/00
Filed: 1967-09-30
Abstract: Microcrystalline ammonium nitrate with a lipophilic surface is produced by crystallization from concentrated or saturated aqueous solutions of NH 4 NO 3 in the simultaneous presence of salts of primary amino-alkanes in an amount of 0À1 to 5% by weight of NH 4 NO 3 , their chain lengths ranging from C 8 to C 18 , and salts of short chain amino alkanols containing 2 to 4 carbon atoms per hydrocarbon chain in an amount of 0.2 to 5% by weight of NH 4 NO 3 , at a temperature between 20 and 90 C. Crystallization may be effected by cooling, evaporation at atmospheric or reduced pressure, or by spray drying. Suitable salts are those derived from acetic, formic, lactic or nitric acid such as ndodecylamine acetate, tetradecylamine lactate, triethanolamine acetate, 2-amino-2-methyl-1- propanol - lactate, 2 - dimethyl amino - ethanol acetate. The ammonium nitrate crystal surface has the physical characteristic of a hydrocarbon chain and is capable of adsorbing organic liquids. It is also hydrophilic. The ammonium nitrate can be used in making explosives or blasting agents and those with Fuel Oil No. 4 retain their normal explosion characteristics and sensitivity towards detonators No. 6 or No. 8 even after storing for six months.
Patent ES-348389-A1 (ES)
Title: Self-adjusting mechanisms
IPC: F16D65/14
Filed: 1967-12-18
Abstract: An automatically length adjusting force transmitting device comprises two members in screw threaded engagement, the co-efficient of friction between the mating flanks on one side of the thread being higher than the other so that longitudinal force in one direction is transmitted by the device but in the other direction causes relative rotation and thus automatic adjustment of the length. The embodiments use the alternative screw and nut arrangements shown in Figs. 2 and 6. In Fig. 2 the faces 30 or 23 of the thread are coated with P.T.F.E. or are separated by a P.T.F.E. insert so that when the screw member 17 is urged to the right the nut will revolve on the thread and the rightward movement is not transmitted to the nut. When the screw is moved to the left the coefficient of friction between faces 31 and 32 is such that the nut does not rotate and the movement is transmitted. In Fig. 6 the left hand end of the nut is formed by a P.T.F.E. insert on a backing 85, locked in position at 87. Its thread has a slight rotational displacement with respect to the rest of the thread so that when the screw is moved to the right, the low friction faces 80, 89 engage, the nut rotates and the movement is not transmitted. If however the screw is moved to the left the higher friction faces 82, 891 engage, preventing rotation of the nut and so allow the movement to be transmitted. The thread arrangements are used in a sliding caliper type disc brake to allow opposed pistons to separate to take up slack but to prevent them being forced together. Thus in Fig. 1, when fluid pressure is applied between pistons 10 and 11 in a cylinder (not shown), nut 24 is allowed to rotate by the low friction of the engaging thread faces and the low friction bearing 25. The pistons will therefore separate. Piston 10 directly actuates one brake pad and piston 11 indirectly operates the other by sliding a caliper housing to the right. The pistons do not close together when the fluid pressure is released and slack is therefore taken up. When the brake is actuated by the cam and strut mechanism 14, 15, 16, the higher friction thread faces engage, the nut does not rotate and the pistons separate. Slack in the thread allows a running clearance for the brake pads and a spring washer 27 provides friction to allow the nut to be screwed back by the piston when replacing the pads. The Fig. 6 thread may alternatively be used in the Fig. 1 embodiment (Fig. 8, not shown). In Fig. 4 the unidirectional screw and nut assembly 47, 61 is located in an inner chamber out of contact with the fluid and the screw 47 is the rotatable member. High levels of fluid pressure separate the piston head 60 from the piston body 61 to prevent excessive slack adjustment and to allow fluid pressure to operate over the whole internal area of the piston. The piston head may however be integral with the piston body (Fig. 3, not shown).

Title: Drive system for bag machine
IPC: B31B23/00
Filed: 1972-11-10
Abstract: The invention is a cooling pillow container insert (10) which provides a continuous cool pillow surface and absorbs a pillow user's lost metabolic heat. Preventing thermal discomfort which causes pillow flipping and tossing and turning is the primary goal of the invention. The container (10) slides between a conventional pillow (12) and pillow case (11). The container (10) is composed of a soft vinyl bag (13) which snugly surrounds a fluid saturated porous foam core (15). A resealable valve (29) allows fluid to be added or removed at will and the container's temperature to be adjusted. The container (10) promotes heat transfer from the pillow user (60) to the container (10). The heat is then dispersed uniformly throughout the container's fluid ensuring a uniformly cool pillow surface. Heat is also continuously lost to the surrounding environment. A pillow user's sleep is enhanced in warm temperatures without using an energy source. The container insert (10) can also be used with or without a pillow, as a cooling bed for an animal or a pet (71).
