Title: Devices for recirculating exhaust gases in internal bombustion  engines
IPC: F02M25/07
Filed: 1971-06-03
Abstract: 1343946 Recirculating exhaust gas in I. C. engines REGIE NATIONALE DES USINES RENAULT and AUTOMOBILES PEUGEOT 3 June 1971 [12 June 1970 26 Nov 1970] 18896/71 Heading F1B [Also in Division F2] Exhaust gases are selectively recirculated through a control valve 5, Fig.1 between a muffler 4 and an induction manifold 2 as a function of specific engine operating conditions, the recirculation taking place during the engine cranking period before ignition after which it is stopped, during low engine speeds when the induction vacuum is above a pre-adjusted value and is stopped when the vacuum drops below the value and when the engine operates under full load conditions. When starter motor switch 31 is closed the energization of coil 29 moves rod 20 to compress spring 26 and unseat needle valve 9 to inter-connect pipes 6 and 7. The opening of switch 31 when ignition occurs results in the seating of valve 9. The valve is opened again when the inlet vacuum communicated via pipe 23 to casing 22 exceeds a predetermined value, the latter being adjusted as a function of the compression of spring 26. When the accelerator pedal is fully depressed switch 32, together with a switch controlling valve 34 is closed to start recirculation. In a modification a recirculation valve is controlled by manifold depression alone, the electromagnetic control being separate (not described). The pipe(50), Fig.2 (not shown) communicates the induction manifold downstream of the carburettor throttle to move diaphragm 47 against spring 51 thereby opening valve 39 to start recirculation.

Title: Improvements in or relating to the hydrolysis of pectin
IPC: C08B37/06
Filed: 1946-06-25
Abstract: Pectinic acids are made by hydrolyzing, preferably in aqueous medium, solutions or suspensions of pectin with alkali at 0 DEG  - 30 DEG  C. under non-oxidizing conditions maintained by displacing the air above the liquid with a gas such as nitrogen or by adding to the liquid a substance such as hydroquinone or pyrogallol.  The pectin may be extracted from apple pomace or grapefruit peel.  The alkali may be sodium, potassium or ammonium hydroxide or carbonate or a quaternary ammonium base, e.g. tetramethyl or tetraethyl ammonium hydroxide. Hydrolysis is terminated by neutralization with dilute sulphuric or hydrochloric acid.  Pectinic acid in which 50 - 60 per cent of acid groups remain esterified, giving with sugar jellies of low setting temperature, is formed in half an hour at 5 DEG  C. at pH10, and pectinic acid in which only 30 per cent of acid groups remain esterified, giving jellies with low concentrations of, or no, sugar, is formed in half an hour at 5 DEG  C. at pH 11.5. Specification 541,528 is referred to.ALSO:Pectinic acids are made by hydrolyzing pectin with alkali at 0 DEG -30 DEG C. under non-oxidizing conditions.

Abstract: 1,062,276. Transformers and inductors; magnetic structures. PHYSICAL SCIENCES CORPORATION. May 7, 1964, No. 19101/64. Headings H1H and H1T. To secure substantially constant magnetic characteristics over an extended temperature range a magnetic core, of a chromium stainless steel which is hardenable martensite, is subjected to a number of successive thermal shock cycles. The temperature is taken abruptly from room temperature to the upper and lower extremes and is returned slowly to room temperature. On the first cycle the upper temperature is 1500‹ F. (for 10 hours) and for the next two cycles 1100‹ F. (for one hour), a lower temperature of - 320‹ F. being secured in each cycle by immersion in liquid nitrogen. After the third cycle the core is machined to 1/4 inch diameter and then taken through a further cycle after which it is machined to # inch diameter and an axial hole is drilled. A final cycle to remove the drilling stresses then involves heating to 1100‹ F. for 1/4 hour, returning to room temperature and dropping in liquid nitrogen after which the core is centreless ground. The core alloy may include 12-14% chromium, 0.5% nickel, 1.25% manganese, 1% silicon, 0.15% carbon and a minimum of 0À07% phosphorous, sulphur or selenium or a maximum of 0.06% zirconium or molybdenum. A transducer incorporating such a core and forming the subject of Specification 1,062,277 is also described.
