Title: Improvements in or relating to Rotary Positive Displacement Pumps.
IPC: F04C2/344
Filed: 1967-06-07
Abstract: 1,185,483. Rotary positive-displacement pumps; jet pumps. ROBERT BOSCH G. m.b.H. June 7, 1967 [June 18, 1966], No.26258/67. Headings F1E and F1F. In a rotary positive-displacement hydraulic pump the rate of flow of working fluid in an outlet bore 38 is controlled, and cavitation in spaces between a vaned rotor 29 and abutment ring 12 obviated, by a proportion of the fluid in a passage 37 being drawn through a bye-pass bore 40 into a diffuser by incoming fluid issuing from a tubular member 47 on a spring-loaded piston 49, the diffuser including a conic bore 50, a bore 51 and divergent passages, or branches, 52, 53 communicating at their ends 54, 55 with said spaces between outlet passages 34, 35, which are connected to the passage 37 by an annular chamber 36. When the speed of the rotor is relatively low, the tubular member abuts a ring 57 to prevent flow through the bore 40; and, by virtue of an orifice 43 at the entrance to the bore 38 and a channel 44 transmitting pressure in the last said bore to the upper side of the piston, when the speed of the rotor is sufficiently great the piston is raised to initiate flow in the bye-pass bore. If the pressure in the bore 38 becomes excessive, a spring-loaded valve 60 opens to increase the flow through the bore 51 and hence that through the bore 40 also. A Venturi D is included in the bore 40 (not shown in Fig.1) to ensure a substantially constant flow-rate in the bore 38 despite variations in the speed of the rotor. A bearing body 16 for a driving shaft 22 is axially movable and loaded by pressure in the chamber 36.

The needle 11 serves to introduce a flexible plastics catheter 15 into a vein or other blood vessel, the catheter 15 being attached to hub 16 and thereby to a fitting 17 on the distal end of hub 13. The plug 20 includes a surface 21 suitable for gripping, and a tapered neck portion 22 for insertion into the chamber 14. Introduction of the needle point 12 into a vein causes blood to flow through the needle into chamber 14, and air in the needle and chamber will be forced through slit 24 to atmosphere. Blood flowing into the chamber 14 can be seen by the operator as an indication that the needle is in the blood vessel. Because of the small size of the slit 24, blood will be retained within the chamber. When located in the vessel, the needle can be withdrawn, leaving the catheter in place for the attachment of an administration set, or other device. Alternatively the needle may be used without the catheter, and the administration set, etc may be attached to it directly.

Title: Improvements in or relating to the production of nitropolystyrene
IPC: C08F8/30
Filed: 1946-09-04
Abstract: Nitropolystyrene containing from 9.4 to 14.4 per cent of nitrogen is prepared by adding one part of granular polystyrene to at least eight parts of a nitrating acid of an analytically determinable composition of 90-60 per cent nitric acid, 10-40 per cent sulphuric acid or oleum calculated as sulphuric acid and 8 to -3 per cent water (by difference), stirring and cooling the acid during the addition until the suspension is dissolved to form a viscous liquid and then precipitating, e.g. by pouring it into water or diluted refuse acid of at least 40 per cent water content or by adding concentrated sulphuric acid.  The nitrating acid is preferably at a temperature of 0 DEG  to -15 DEG  C. and the polystyrene added quickly with stirring, the nitration continuing at a temperature of between 0 DEG and 60 DEG  C.  The nitropolystyrene may be purified by washing with cold water, steaming for one hour at 90-100 DEG  C. and grinding under water.  The products are soluble in nitric acid, nitroglycerine and dinitroglycol.  Those with a nitrogen content above 11.8 per cent are also soluble in aldehydes and ketones such as cyclohexanone, cyclopentanone and furfural. They can be plasticised by most liquid aromatic and aliphatic nitro-compounds, e.g. dinitrotoluene mixture oil, nitrobenzene and nitromethane.  The nitropolystyrenes are useful as binding agents for explosive and incendiary compositions and as hard, water-repellent coatings.
