Patent GB-919268-A (GB)
Abstract: 919,268. Esters of hydroxy halo-quinaldines. SANDOZ Ltd. Nov. 30, 1960 [Dec. 23, 1959; March 8. 1960; March 28, 1960; May 9, 1960], No. 41171/60. Class 2(3). The invention comprises esters of the general formula where R<SP>1</SP> represents an alkyl group containing 1-5 carbon atoms or a phenyl group which may be substituted by a monovalent radical; R<SP>11</SP> is hydrogen or methyl; X and Y are chlorine, bromine or iodine and may be the same or different. The esters are prepared from the corresponding phenols by reaction with an acid chloride, R<SP>1</SP>COCl, preferably in an inert solvent e.g. benzene, toluene, xylene, pyridine, or with an acid anhydride (R 1 CO) 2 O for example in the presence of an acylation catalyst e.g. conc sulphuric acid, pyridine, or with a mixture of the acid chloride and anhydride. The quinaldine esters prepared in the examples are 5.7 dichloro-8-acetoxy-quinaldine, 5:7 dibromo-8-acetoxy-quinaldine; 5-chloro-7-bromo- 8-acetoxy quinaldine; 5.7 dibromo-8-benzoxy quinaldine; 5:7 diiodo-8-acetoxy quinaldine; 5:7 dichloro-8-benzoxy quinaldine; 5:7 dibromo-8-(p-chlorobenzoxy)quinaldine; 5:7 dibromo-8-(p-nitrobenzoxy)quinaldine; 5-chloro- 7 - bromo - 8 - (p-chlorobenzoxy)quinaldine; 5- chloro-7-bromo-8-benzoxy quinaldine; 5-chloro- 7-bromo-8-(p-nitrobenzoxy)quinaldine; 5:7-dichloro-8-(p-chlorobenzoxy)quinaldine; 5:7-dichloro-8-(p-nitrobenzoxy)quinaldine; 3-methyl- 5:7-dibromo-8-acetoxy quinaldine; 3-methyl- 5 : 7-dibromo-8-benzoxy quinaldine; 3-methyl- 5; 7-dibromo-8-(p-chlorobenzoxy)quinaldine; 3- methyl-5: 7-dibromo-8-(pnitrobenzoxy)quinaldine and 5 : 7-diiodo-8-benzoxy quinaldine. The esters have antiseptic properties. 5,7-dihalo-8-hydroxy quinaldines used as starting materials, wherein the two halogen substituents are the same, are prepared by reacting' the 5,7-unsubstituted hydroxy quinaldines with a chlorination, bromination or iodination agent. Thus, 3-methyl-5,7-dibromo- 8-hydroxy quinaldine is prepared by reacting the 3 - methyl - 8 - hydroxy quinaldine with bromine in formic acid. When the two halogen substituents are different they are obtained by stepwise mono-halogenation.

The actuator is supplied from a branch off said emergency brake line. <IMAGE>
Patent GB-2288586-A (GB)
Title: A palletiser
Inventor: TAYLOR ELLIS JOHN
IPC: B65G57/22
Filed: 1993-12-01
Abstract: Articles (40) to be palletised are picked up by vacuum gripper (30) from conveyor (60) (alternatively the gripper may have tines which interleave with rollers of the conveyor (60) to lift the article from below). The gripper (30) is translated (21) by a carriage along track (20) which in turn may be translated (12) along track (10) to provide the two dimensional horizontal movement required if an article is to be deposited at a selected position on pallet (57). Once a layer of articles (40) is filled, the pallettable (51) is lowered so that the next layer can be filled with minimum vertical movement of the gripper. Instead of cantilevering the track (20) this track may be supported at its far end by a further track parallel to track (10). In this case the pallet table may be moved by chain drives concealed in the posts supporting these parallel tracks. Any horizontal rotation required of articles (40) may be provided by rotating one of the gripper, the pallet table or the feed point of the conveyor. If desired the track (20) may be elongated so that a second gripper can be carried thereon or extra tracks parallel to track (20) may be used. If multiple gripper units are used then it is best if they work in unison. <IMAGE>
