Abstract: 1454987 Jet propulsion nozzles GENERAL MOTORS CORP 19 April 1971 [8 June 1970]  23742/71 Heading F1J The exhaust duct of a turbojet engine, which is annular with an enlarged plug or bullet at the exhaust end, includes an arrangement of the outer wall to block direct sight of the turbine of the engine through the exhaust duct, and hence to minimise infrared radiation from the hot parts of the engine. There are two rings of inwardly directed streamlined holes on the outer wall of the exhaust duct with the lobes of one ring staggered with respect to those of the other so that the two sets co-operate to block direct viewing through the duct. With this arrangement of staggered lobes, the reduction of duct crosssectional area is considerably less than would be the result of a necking in or convergence extending entirely around one axial plane of the duct. It is desirable that the downstream surfaces of the lobes be cooled to reduce radiation.

Title: Improvements relating to the separation of meta-cresol from liquid phenolic mixtures containing it
IPC: C07C39/07
Filed: 1934-08-17
Abstract: In the separation of meta-cresol from liquid phenolic mixtures containing it by forming a solid addition product thereof with anhydrous sodium acetate and separating, the addition product is decomposed into its constituents with the action of heat, in the absence of water and preferably in the presence of an inert non-aqueous solvent for m-cresol, which is thereafter separated by fractional distillation.  The anhydrous sodium acetate recovered may be re-used in the process.  According to an example, the separated solid addition product, formed in a solvent of petroleum naphtha of specified boiling range, is washed and heated to boiling with more of the solvent, filtered and the decomposition repeated with two fresh portions of solvent.  m-Cresol is thereafter obtained by fractional distillation from the filtrates. Other solvents specified include petroleum naphtha of different boiling ranges, benzene and similar aromatic hydrocarbons, and carbon tetrachloride.  The decomposition may also be effected at increased pressures, and without a solvent, at reduced pressures. Specification 107,961, [Class 2 (iii)], is referred to.

Abstract: 782,542. Cutting-machines. SCHULPEN, K. H. N. Aug. 19, 1955 [Aug. 26, 1954], No. 23929/55. Class 31 (1). [Also in Group XXIII] In a machine for cutting out articles of tapering curved section, such as shoulder pads, an endless or reciprocated saw or knife 7 is guided with its cutting edge projecting over a pattern member 3 which makes it conform to the curved cross-section of the article and after a first cut is made at an angle across a bar of foamed plastic material held in a frame 29 pivoted at 30, the bar is fed by distance greater than half the maximum thickness of the shoulder pad and the frame 29 is pivoted over to an equal, opposite angle so that a second cut severs a shoulder pad which is generally triangular in longitudinal crosssection. A pair of saws or knives 7, or several pairs one above the other, are fixed on rods 4, 5 and driven separately by motors 8 and the frame 29 is pivoted on a carriage 21 reciprocated by a chain 27 having a pin engaged in a slot on a member projecting down from the carriage. A lever 34 adjustably pivoted at 33 on the carriage is connected by a ball joint 35 to the frame 29 and at the other end moves in a slot 36 having a raised portion 37 and a recess 38 so that the frame 29 is oscillated about the pivot 30 as the carriage reciprocates. A slide 39 carrying the bar of material and mounted on the frame 29 is connected to a weighted cable 41 and is released for step-by-step movement by an escapement comprising a lever 44 which has two pins engaging recesses 42 in the slide 39 and is connected to two weighted cables 45 which alternately slacken and tauten as the frame 29 oscillates. To prevent the saw or knife running off the edge of the pattern member 3, projections 11 or a continuous strip on the underside engage a groove 10 in the pattern member and, to reduce wear, the driving motors 8 are switched off after each cut by an abutment engaging a switch. A gripper 20 pivoted on a rod 19 is operated by a one-way pawl 22 mounted on the carriage 21 and acting on the shorter or longer leg 13 or 12 of a spring-loaded pivoted fork, the fork moving with an over-centre action so that the gripper moves the portion 51 being cut slightly away from the bar of material and then releases it when it has been completely severed. The shaping member and the saw or knife may be moved together to cut into a stationary bar of material and the shaping members and the carriages may be moved by hand.
