Novel compounds have the formula where R<SP>1</SP> is C 1-4  alkyl, R<SP>2</SP> and R<SP>3</SP> are alike or different and represent H or C 1-4  alkyl, X is halo, Q is carboxy, alkoxycarbonyl, carbamoyl, alkylcarbamoyl or dialkylcarbamoyl (the alkyl radicals being C 1-4  alkyl) and n is an integer from 1-4. Esters of Formula (I) where Q is alkoxycarbonyl are obtained by converting a phenol of the formula to the alkali metal salt in anhydrous C 1-8  alcohol solution and coupling this with an alkyl haloalkanoate. Amides of Formula (I) wherein Q is carbamoyl, alkylcarbamoyl or dialkylcarbamoyl are obtained by subjecting the corresponding ester (Q = C 1-4  alkoxycarbonyl) to aminolysis with a basic nitrogenous compound, e.g. ammonia, or a primary or secondary amine. Acids of Formula (I) where Q is COOH are obtained by saponification of the corresponding esters (Q is C 1-4  alkoxycarbonyl) followed by acidification. The acids and esters may also be obtained by reacting a phenol of Formula (II) with a haloalkanoic acid, optionally followed by esterification to produce the alkyl ester. In Example (IV) a further method is described which comprises reacting 3,5-diiodo-4-(3,5-dimethyl- 4-methoxyphenoxy)-phenol with acetone and chloroform in the presence of NaOH to form 2 - methyl - 2 - [3,5 - diiodo - 4 - (3,5 - dimethyl- 4 - methoxyphenoxy) - phenoxy] - propionic acid.

Title: Improvements in or relating to scraping devices for removing scale from hot rolled strip metal
IPC: B21B28/04
Filed: 1928-03-16
Abstract: 310,150. Parkes & Co., Ltd., E., and Parkes, H. H. March 16, 1928. Cleaning.-In a scraping device for removing scale from hot rolled strip metal in which the scrapers are automatically brought into action when the strip enters between the rolls, the lifting movement of the top roll or a part connected thereto is transmitted by suitable connections to a control device for the scrapers. The roller 14 in contact with the upper roll is mounted on a bell-crank lever 13 pivoted to a bracket 14<a> carried by a guide for a slide 1 which carries at its lower end scrapers 6 which co-operate with fixed scrapers 5 mounted on the guide frame. The slide 1 is held in the raised position by means of the bent end of a lever 7 pivoted to a bracket 10 fixed to a guide member, the bent end passing through a slot in the guide member and entering a slot in the slide 1. The other end of the lever 7 abuts against the end of a spring 11 interposed between the lever and the bottom of a recess in the guide member, and on its other side is provided with an adjustable pin 12 which contacts with one end of the lever 13. When the roller 14 is raised bv the movement of the upper roll the bent end of the lever 7 is removed from the slot 9 in the slide 1 which immediately falls by its own weight, thus bringing the scrapers 6 into contact with the strip on each side of the scrapers 5. In a modification, Fig. 3, a roller 21 contacting with the upper roll is carried by a spring-controlled slide 19 connected by a link 20 to a pivoted lever 18 which is connected by a resilient link 17 to a lever 15 pivoted on a support 16 and connected to the valve control of an hydraulic apparatus operating the scraper.

Title: Hydropneumatic suspension for vehicles
IPC: B60G15/12
Filed: 1961-03-06
Abstract: 972,765. Levelling springs. FICHTEL & SACHS A.G. March 6, 1961 [April 1, 1960], No. 8053/61. Heading F2S. A hydropneumatic suspension device having a levelling action comprises a cylinder 1 separated from a liquid reservoir 7 by a partition having passages 16 controlled by a flexible ring 14, acting as a one-way valve, a piston-rod 17 passing through the partition, which is provided with a sealing ring 11, having a piston 2 acting in the cylinder 1 which has at its closed end a gas chamber 5 separated from the liquid within the cylinder by a floating piston 6. The piston 2 is provided with passages closed by a non- return flap valve 28 and grooves 8 and 9 are provided in the cylinder and piston-rod respectively. A sealing ring 27 co-operates with passages in the reservoir 7 to act as a one-way valve to enable the space above the liquid to be filled with gas under pressure. The pistonrod 17 is connected to the chassis of the vehicle and the cylinder 1 to an axle. In action, load upon the piston-rod 17 compresses the gas in chamber 5, the piston 2 descending until it sinks below the grooves 8. Upward movement of the piston due to vehicle vibration cause liquid to pass the non-return valve 28 until the piston 2 registers with the grooves 8. Due to the load upon the spring, the liquid in the cylinder 1 is at a higher pressure than that in the reservoir 7. If a rebound causes the piston 2 to ascend to a position whereby the grooves 9 connect the cylinder 1 with the reservoir 7 liquid will be forced into the reservoir, but on return downward movement of the piston 2, liquid will reenter the cylinder 1 through the passages 16. In a modification, Fig. 2, the grooves 8 internally of the cylinder 1 are replaced by grooves 10 externally of the cylinder and communicate therewith through ports 12 and 13, the latter being closed by a non-return valve 15. In a further modification, Fig. 3, the reservoir of liquid is contained within the piston-rod 17 and communicates with the upper cylinder space 3 through ports 26 closed by a ring 20 held in place by a spring and provided with a flexible sleeve 21 acting as a one-way valve which permits flow of fluid from the reservoir into the cylinder 1 when the pressure therein is below that of the reservoir. At extreme upward movement of the piston-rod, the ring 20 is dislodged by a fixed ring 29a to place the cylinder and reservoir into communication. The ports 12 leading into the annular communication space 24a are normally closed by a flexible sleeve 31 acting as a one-way valve. Fig. 4 shows a modification of Fig. 3 wherein access between the reservoir within the piston 17 and the interior of the cylinder is provided by ports 22 and 33a, the latter being associated with a sleeve valve 33, the ring 29a being omitted and a series of large ports 23 being provided which coact with the ports 22 at the upward position of the piston.
