Title: Improvements in and relating to Fuel Injection Valves
IPC: F02M45/08
Filed: 1967-03-29
Abstract: 1,178,486. Fuel injectors. ROBERT BOSCH G.m.b.H. March 29, 1967 [March 30, 1966], No.14263/67. Heading F1B. In a fuel injection valve having a fuel pressure opened valve needle 8 moving against a spring 24 variably loaded by a piston 7 which is acted upon by fuel pressure and controls a main injection supply channel 20, a fixed pressure-moved preinjection piston 6 displaces a pre-injection quantity into a pressure chamber 17 until its movement is limited by a stop after further increase of fuel pressure and thereby increases the spring force before still further rise in pressure causes the opening of the valve needle for the main injection, the unthrottled fuel pressure acts constantly on the pre-injection and loading pistons and the effective area of the valve needle is greater or less than the effective area of the loading piston when the needle valve is respectively closed or open. Operation: Fuel from passage 9 passes via passages 10, 11 to move the pre-injection piston against spring 12 until it abuts sleeve 13. The fuel displaced lifts the valve needle 8 off its seat to inject the pre-injection quantity and also increases the force applied by spring 24 on the loading piston 7. When the pressure in chamber 17 falls the valve needle 8 recloses. A non- return valve 21 prevents the pressure in chamber 17 from acting directly on the loading piston 7. When the pressure in passage 9 exceeds the preinjection pressure the loading piston 7 is moved into contact with stop 1a to permit fuel flow via passage 20 into the pressure chamber 17, the needle valve 8 being unseated to start the main injection. The movement of the loading piston compresses the spring 24 to increase the main injection pressure above the pre-injection pressure. Excess pressures in chamber 17 are relieved through non-return valve 15.

Title: Improvements in or relating to protective arrangements for vapour electric arc converters
Inventor: MITCHELL JAMES DURNO
IPC: H02H7/127
Filed: 1959-04-28
Abstract: 914,603. Converting. GENERAL ELECTRIC CO. Ltd. April 28, 1960 [April 28, 1959], No. 14454/59. Class 38 (2). In, a vapour arc converter comprising single anode type converter vessels 1 which each have a continuously excited auxiliary anode 2 for maintaining the cathode spot, protection against reverse current is effected by a silicon controlled rectifier 10 which short-circuits the auxiliary anode if a back-fire occurs. The normal supply to the auxiliary anodes is provided by a supply 5 rectified by a bridge 6 and filtered by a circuit 8, 9. A reverse current is detected by a current transformer 35 which applies a signal across a resistor 39 in the grid circuit of a thyratron 11, overcoming the bias on this valve and causing it to conduct. This causes a current to be fed through a resistor 16 to the gate electrode of the silicon-controlled rectifier 10 rendering this conductive to shortcircuit the auxiliary anode 2. The bias for the thyratron is derived from an A.C. supply through a bridge 29, and a relay 28 is provided to short-circuit the thyratron when conduction commences. To enable the converters to be restarted a press-button 25 is provided which breaks the circuit to the relay 28. Specification 817,504 is referred to.

As the diameter of the roll 18 of fabric on a take-up beam 17 increases, the drive roller 10, which bears on the roll, is swung outwardly at the end of arms 9 which carry it and which are pivoted in bearings 8, until first, segments 11 borne on the arms are moved clear of pins 6 on rods 5 to free the rods and next, the rods are lifted vertically by abutment of the arms on other pins 7 which the rods carry. By reason of the segments 11, the beam is held in its bearings until the roll of fabric is heavy enough to prevent its accidental removal by the tension on the fabric. To introduce a new beam 17, the arms 9 are raised manually to raise the rods 5 clear of the bearings 4 and the new beam is introduced into forked ends of the rods, which are then lowered to allow the beam to seat itself in the bearings. Reference has been directed by the Comptroller to Specifications 756,129 and 795,368.

Abstract: 531,681. Heat treating light alloys. PRESSED STEEL CO., Ltd., ARROWSMITH, J. C., and ROWLEDGE, E. G. May 19, 1939, No. 14903. [Class 72] To ensure that blanks of light metal alloys, particularly aluminium alloys, can be stored for some time without age-hardening, the blanks are first heated to the solution temperature, quenched to room temperature and, their temperature is rapidly lowered by immersion to that of a refrigerated chamber in which they are stored before use the temperature of which is substantially the same as the immersion bath. The blanks are heated in a salt bath, quenched in cold water or other medium such as oil, rinsed free of salt, and then immersed in a bath of paraffin or methyl alcohol maintained at a temperature of 0‹C. to -20‹C. The blanks are then stored in a refrigerator maintained at 0-‹C. or less, e.g. -2‹C. The latter temperature may be used for storage for 48 hours but if the storage period extends to a much longer period, e.g. 168 hours, the temperature should be -20‹C. The process may be carried out in a salt bath or circulated air furnace, a quenching tank and an immersion bath disposed within a refrigerator storage chamber.
