Title: Fuel injection nozzles for internal combustion engines
IPC: F02M61/16
Filed: 1972-10-20
Abstract: 1355759 Fuel injectors ROBERT BOSCH GmbH 20 Oct 1972 [23 Oct 1971] 48349/72 Heading F1B A fuel injection nozzle for an I. C. engine comprises a nozzle body 1 with a needle 2 therein, a pressure chamber 5, to which in use a fuel supply line is connected, and a pocket 7, with spray openings 8 to discharge fuel into the combustion chamber, being defined between needle 2 and body 1 and separated by the needle and a valve seat 9. The needle 2 has a cylindrical cavity containing an axially slidable piston 16 which separates the cavity into a chamber connected to the pressure chamber 5 and a chamber connected to the pocket 7. Immediately after needle 2 closes on to seat 9, the pressure of fuel supplied to chamber 5 falls and the pressure in the combustion chamber forces fuel from pocket 7 via a bore 18 into chamber 17, to prevent coking, thereby displacing piston 16. When the new pressure stroke begins, fuel passes via bores 19 to actuate piston 16 to expel fuel from chamber 17 to pocket 7 so that injection starts as soon as needle 12 is raised from seat 9. A spring 20 acts on piston 16, which can have rounded endfaces.

Abstract: 1359060 Breeding shrimp H N BRAUNHUT 27 Oct 1971 [12 Nov 1970] 49940/71 Heading A1A A composition for hatching and observing the development of brine shrimp is made up of two groups: a first group containing salts, a chlorine-removing agent, dried eggs and a drying agent, and a second group containing dye. When the first group is disposed in water the salts create a saline environment in which the eggs are able to hatch, the harmful chlorine being removed in the case of tap water. After hatching, the shrimp are not visible until the second group is added, creating the impression of instant life. The drying agent prevents premature hatching of the eggs. The second group may contain additional salts, eggs, drying agent and also yeast for food. A suitable composition of the first group is: iodine-free sodium chloride, Epsom salts, sodium sulphate, light soda ash, potassium chloride, calcium chloride (drying agent) magnesium chloride, sodium thiosulphate (chlorine removing agent), Artemia salina eggs. A suitable composition of the second group is: anhydrous Epsom salts (drying agent), hydrated Epsom salts, borax 40/200, light soda ash, diamond-structured soda crystals, yeast, watersoluble dye, Artemia salina eggs. Preferably one ounce of each group is present for each 12 fluid ounces of water.

An integrated pressurized water reactor has a generally spherical pressure vessel containing heat exchange elements encircling a generally cylindrical space and extending between the top and bottom of the space, a reactor core disposed in the lower end of the space, and a pressurizer having a shell open at its lower end, means for heating water in the shell and means for cooling vapour in the shell, the lower end of the shell projecting into the cylindrical space and lying below the water level in the pressure vessel. In the embodiment described, the shell is in the form of a cylindrical drum 8 having a flange 8a at its upper end which is clamped between the body and the cap 2b of the pressure vessel 2. The reactor core 1 is encircled by a shielding 3 and in the space between the shielding 3 and the pressure vessel 2 are steam generating tube banks 4. The tube banks 4 are contained within a casing 5 and immersed in water reaching to the level 6. The water is circulated by means of pumps 7. The vapour pressure in the pressurizer space above the water level 6 in the drum 8 is controlled by means of electrically heated immersion elements 10 disposed on a circle near the periphery of the drum 8 beneath the water level 6 and a spray device 11 disposed above the water level 6 so that cold water may be sprayed into the pressurizer space. By suitable operation of the pressurizer, steam bubble formation in the core may be limited although some steam bubble formation can still occur and thus may be useful in providing some automatic control of the operation of the reactor..

In a rotary press comprising a ductor roller 27, Fig. 2, in direct contact with the printing cylinder 25 the roller forms with an adjustable scraper blade mechanism 28 a trough-like openended ink fountain to which ink is pumped through a circulatory system from a nozzle 69 positioned above the fountain above the level of ink therein at a point mid-way along the length of the fountain. Ink flowing from the fountain is caught in a pan therebeneath for recirculation. The blade mechanism 28 carries a non-metallic blade 31, Fig. 5, held, when operative, against the ductor roller 27 through readily adjustable fluid operated piston and cylinder devices 42, 43. To allow ready access to the blade 31 for purposes of renewal &c. the mechanism 28 is swingable about a pivot axis through handles 52. Automatic means are provided such that upon stripping the printing cylinder 25 the roller 27 and an impression cylinder 26 automatically fall away from the printing cylinder. The blade 31 and the roller 27 are mounted on a common support so that even when the roller 27 moves from the printing cylinder the relationship between the roller and the blade is not disturbed.  Furthermore, clutch means are provided to enable the press to be driven by a motor other than the main motor for proofing purposes. This other motor also rotates the ductor roller 27 when the machine is stopped in order to prevent the ink hardening thereon. The impression and printing cylinders are mounted in eccentric bearings. The press forms a part of a box-blank machine and is readily removable as a unit from the machine through being mounted on wheels running along a track.

Abstract: 1,148,895. Rolling. UNITED ENG. & FOUNDRY CO. 18 July, 1966 [6 Dec., 1965] No. 51698/65. Heading B3M. A rolling mill includes a pair of removable inserts 31, 32 for each housing, the inserts incorporating cylinders 37 for balancing the chocks 17 and 19 of backing rolls 16 and 18, and further cylinders 38 and 42 for balancing work roll chocks 13 and 15. The cylinders 37 can alternatively be replaced by a single cylinder at the top of the mill. The chocks 13 for an upper work roll 12 are provided with wheel carrying legs 20, and with stops 21 for supporting the chocks 15, thus enabling the work roll assemblies to be removed as a unit from the mill on rails 43. The rails also serve to support a carriage for removing the inserts 31 and 32. To remove the work rolls, the cylinders 38 are collapsed and the cylinders 37 operated to lift the chocks 17, bolts 65 holding the chocks in a raised position. Wheels 46 carried by the chocks thereby lift the chocks 13 and hence the lower chocks 15, to a position in which the wheels 20a are aligned with the rails 43. Slots in the rails permit the vertical movement of the wheels 20a, while the wheels 46 serve to support the roll assembly while it is initially shifted axially on to the rails 43. The assembly can then readily be drawn clear of the mill using a carriage 70, Fig. 2. A pair of arms 76 on the carriage are movable laterally towards and away from each other to allow their engagement with similar arms 75 on the chock 13. When the work rolls have been removed, a carriage 50 is inserted within the housings, the wheels 46 and rails 43 supporting the carriage. A jack 55 on the carriage lifts platforms 57 into engagement with the inserts 31 and 32, thus raising the inserts. The lips 34 (Fig. 1) of the inserts disengage grooves 33 in the housings, further lips and grooves 62, 63 then supporting the inserts on the carriage. The carriage is then withdrawn from the mill using the carriage 70.
