Title: A manufacture of new naphthalene derivatives
IPC: C07C45/41
Filed: 1949-09-06
Abstract: A b -naphthyl-(2)-propionaldehyde or propanol is obtained from the corresponding b -naphthyl-(2)-a :a -dialkyl-b -alkyl propionic acid, or a derivative thereof which is reducible to an aldehyde or alcohol, by means of a reducing agent, and, if desired, the aldehyde is converted into an acetal or thioacetal, or the alcohol into an ester or ether.  The starting materials may be further substituted, e.g. in the 6-position of the naphthalene nucleus by a free or substituted hydroxyl group.  Acid derivatives employed may be the chlorides, esters, thiol esters, anhydrides, imide halides, imidoethers or diaryl amidines or the corresponding aldehyde, e.g. b -naphthyl-(2)-a :a -dialkyl-b -alkyl-propionic acids and derivatives; b -(6-methoxy - naphthyl - 2) - a :a  - dimethyl - b  -methyl or ethyl propionic acid; b -naphthyl-(2)-a :a  - dimethyl - b  - ethyl - propionic acid. Acid chlorides are reduced by hydrogen in the presence of e.g. palladium-barium sulphate or palladium-carbon catalysts to aldehydes or alcohols and thiol esters similarly with Raney nickel, depending on the reaction conditions.  Propanols are obtained from the carboxylic acids, esters, acid halides or anhydrides by reaction with a light metal alloy, e.g. lithium aluminium hydride.  The propion-aldehydes obtained can be converted into acetals or thioacetals.  Products containing substituted, e.g. etherified or esterified hydroxyl groups can be converted to hydroxyl groups, and hydroxyl groups in the products can be esterified or etherified.  In examples: (1) b -(6-methoxynaphthyl-2)-a  : a -dimethyl-b -ethyl-propionic acid is converted by treatment with oxalyl chloride to the acid chloride.  The latter is hydrogenated, using a palladium/animal charcoal catalyst.  The product is recovered using Girard reagent P.  The b -(6-methoxynaphthyl-2) - a  : a  - dimethyl - b  - ethyl - propionaldehyde obtained yields the acetal on reaction with glycol and an acid catalyst, or by heating with pyridine hydrochloride the free 6-hydroxy compound is obtained; (2) the aldehyde obtained in (1) is hydrogenated to the corresponding alcohol; (3) g -(6-methoxynaphthyl-2)-b  : b -dimethyl-g -ethylpropyl alcohol is also obtained by reducing b -(6-methoxy-naphthyl-2)-a  : a -dimethyl-b -ethylpropionic acid methyl ester with lithium-aluminium-hydride.  The product is reacted with acetic anhydride to give the acetate; (4) similarly to (1) is prepared the corresponding aldehyde without the 6-methoxy radical; (5) similarly to (3) is obtained the alcohol with a 6 - methoxy substituent.  b  - Naphthyl - (2) - a  : a  - diethyl - b  - propyl - propionic acid is also mentioned as a starting material.

Title: Means for hulling cacao beans
IPC: B02B3/12
Filed: 1956-07-27
Abstract: 801,862. Hulling cacao beans. BUHLER, GEB. July 27, 1956 [March 7, 1956 ; April 19, 1956], No. 23322/56. Class 58. In a machine for hulling cacao beans, the beans are carried in a current of air through a duct, then through a hulling channel into a receiver. The hulling channel has wall surfaces against which the beans impinge. In the construction according to Fig. 1, the beans are drawn through the duct 41 and a zig-zag hulling channel 43 into the receiver 42 in a current of air generated by a suction fan 49 connected to the receiver. The wall 45 of the channel is fixed. The wall 44 pivots about a hinge 53 and is linked to a flexible diaphragm 54 in the wall of the receiver. If the channel 43 becomes choked, the pressure in the receiver is reduced and the diaphragm is pushed inwards by the atmospheric pressure and swings the wall 44 away from the wall 45 to relieve choking. When normal working pressure is restored in the chamber, the diaphragm and the wall 44, assisted by a spring 57, return to their normal positions. In the construction according to Fig 6, cacao beans from a hopper 58 are carried into the receiver 42 through the duct 59 and the hulling channel 43 in a current of air from a blower 60. Air leaves the receiver through a filter bag 61. The hinged wall 44 is linked to a piston 63, subjected on one side to the pressure of air in the duct 59 and on the other side to atmospheric pressure. If the channel 43 becomes choked, the pressure in the duct 59 increases and moves the piston so as to swing the wall 44 away from the wall 45. The hulling channel may be arcuate in shape and may widen towards its outlet, Figs. 9 and 10 (not shown). Its walls may be roughened and perforated.

Filed: 1970-05-14
Abstract: 1306963 Piston-rings; shaft seals GARLOCK Inc 14 May 1970 [27 May 1969] 23448/70 Headings F2B and F2T A seal for a piston or rod comprises a split sealing-ring 17, Fig. 1, which is constantly urged, either by its own resilience or by biasing means, into sealing contact and an endless elastic retaining ring (or rings 21, 23) which provides a radial retaining force on the splitring to reduce the bearing pressure and which expands or contracts as the split-ring is worn away to allow the split-ring to remain in sealing contact. In the piston seal shown, the endless elastic rings 21, 23 permit a uniform pressure to be applied by the split-ring throughout its life. The split-ring may be formed as a spring-ring or as a spring-urged segmental ring and made of P.T.F.E. or metal. The endless rings 21, 23 may be made of metal or plastics having a modulus of elasticity which permits a uniform bearing pressure of the split-ring throughout the life of the split-ring, the modulus being determined by the maximum radial forces occurring in the cycle of the piston. After initial wear of the split-ring 17, clearances 29, 31 are taken-up and the endless rings 21, 23 are stretched into sealing contact. In the rod seal shown in Fig. 3, after the initial wear of the split-ring 37 the endless ring 39 is placed in compresssion and pressed into sealing contact with the rod 35. In Fig. 4 (not shown) the splitring is of T-section and is urged towards the rod by an O-ring (61) having a tensile modulus of elasticity related to the compressional modulus of elasticity of the endless rings (57, 59). In another embodiment, a pair of L-section splitrings co-operate with a single endless ring. In further embodiments, the split-ring is of C- or H-section with the endless rings arranged in the section so that they do not come into sealing contact with the cylinder or rod. Relative rotation between the rings may be prevented by interengagement.
