Abstract: 1,155,029. Isocephalosporanic acid derivatives and process for their preparation. R. B. WOODWARD. 30 Aug., 1966 [9 Dec., 1965], No. 24390/68. Divided out of 1,155,023. Headings C2A and C2C. Compounds of the formula in which R 0  represents a hydrogen atom or an acyl group and R a  stands for hydrogen or the residue of an alcohol, may be obtained by treating a 4,4-disubstituted-3-acyl-α-diformylmethyl- 2 - oxo - 1 - azetidino - [3,2-d] - thiazolidine methane carboxylic acid ester of the formula wherein Ac is an acyl radical and X is the disubstituted carbon atom of the thiazolidine ring, with an acidic agent selected from inorganic oxygen-containing acids, strong organic oxygencontaining acids, boron trifluoride and complexes thereof and tin tetrachloride while splitting the 5-membered sulphur-nitrogen ring and forming the new 6-membered sulphur-nitrogen ring, and optionally converting esterified carboxyl groups in the products to free carboxyl groups. The reaction may be effected in the presence or absence of added solvents with cooling or at ambient or elevated temperatures, and optionally in a nitrogen atmosphere and/or in a closed vessel. A resulting mixture of isomers obtained by the process may be resolved by conventional methods, e.g. by fractional crystallization, adsorption chromatography, and a resulting racemate may be resolved into the antipodes, for example, by forming a mixture of diastereoisomeric salts with optically active salt-forming agents, breaking down the mixture into the diastereoisomeric salts and converting the isolated salts into the free compounds. Inorganic oxygen-containing acids are, for example, sulphuric, phosphoric and perchloric acids, and strong organic oxygencontaining acids are, for example, substituted lower (up to C 7 ) alkane carboxylic acids and strong organic sulphonic acids; aprotic Lewis acids of the boron trifluoride type include boron trifluoride and complexes thereof, e.g. with ether or hydrogen fluoride, as well as tin tetrachloride, and mixtures of acidic agents may be employed. The acyl group R o  in the products may be introduced by treating the free amino compound with a suitable acid or acid chloride or anhydride, and substituent groups in the products may be modified by conventional methods.

Class 83 (4) Relates to rolling mills having one or both of the working rolls freely floating and backed up by cluster rolls and consists in adapting the windowed type of housing for this purpose. Existing mills with driven working rolls may be connected to the above type. As applied to a mill having two working-rolls 4 with backing-rolls 5, the two lower rolls with their chocks are removed from the housing and the bottom of the opening or window of the housing is filled by a cast steel block having side pieces 9, Figs. 2 and 4, that enter the windows and bed at 12, 13 therein. The block has a central portion of channel shape which is bored at 16, 17 to receive the shafts 18 of the main backing rolls 20 which are in the form of three collars 20, Fig. 9, mounted for free rotation on the shafts by antifriction bearings. The ends of the shafts are cut away for fixing in the block by bolts 19.

Title: A process for preparing polyurethane foams
Inventor: POTTER MICHAEL ALAN
IPC: B29C44/40
Filed: 1962-06-27
Abstract: A polyurethane foam is prepared in a mould by feeding the polyurethane reactants to the uppermost portion of the internal wall or walls of said mould and thereby wetting substantially the whole surface of the wall or walls by the action of gravity prior to the mould being filled with said polyurethane reactants.  The width of the mould is preferably less than 3 inches and the mould may be a block mould, e.g. having a base of 1.5 to 3 feet, width less than 3 inches, and height up to 4 feet.  The foams are prepared by reacting a hydroxyl-containing compound, e.g. polyalkylene polyols, polyesters, polyetheresters or polyester amides with a polyisocyanate or a polyisothiocyanate in the presence of a blowing agent. Polyesters may be polyethylene adipate, polyethylene sebacate, poly-1,2-propylene adipate, polyethylene succinate or an alkyd resin, e.g. glycerol phthalate. Also mentioned are polydiethylene glycol adipate and polyethylene glycol hexamethylene diamine adipate-adipamide.  The polyisocyanate and polyisothiocyanates may be aliphatic or aromatic and include dissociable polymers, e.g. dimers or addition products of polyisocyanates or polyisothiocyanates with phenol, or addition products with polyhydroxy or an aliphatic polyhydroxy compound, e.g. dimethylol propane or trimethylol propane. Toluene diisocyanate is preferred.  The foam is produced by blowing the mixture as reaction takes place, by generating CO2 or COS by reaction of the isothiocyanate or isocyanate with a carboxylic acid or water, or preferably by the incorporation of a volatile halohydrocarbon.  Cross-linking agents may be used in preparing the foam and comprise: water, glycols, amines, hydroxy acids and amino acids.  Catalysts, e.g. dibutyl tin dilaurate, and/or surface-active agents may also be used.  The walls of the mould are wetted with reactants by dispersing from a gun or from a boom with a mixing head, to the uppermost part of the wall of the mould.  Long vertical moulds may also be used to produce linings for refrigerators.

A plate 16 is secured (as by welding) to a sidewall of rail 14 and has a bridge 32 stamped therefrom at one end. One end of a lever 40 engages below the bridge 32 and is secured thereto by a pivot 44, a side arm 52 of the lever being projected through a hole 18 in plate 16 in such a position as to be engagable with a cut-out in rail 12 via cut-out 70 in rail 14 to lock the rails together. A hair pin spring 60 biases the lever 40 into the locking position, a handle 56 being provided to operate the lever. An upward projection 54 of the side arm 52 keeps the lever close against plate 16. The plate 16 is symmetrical about its longitudinal centre line so that it is equally useable for left or right handed seats. Holes 46, 48 in the lever allow passage of electrodes for welding the plate 16 to the rail 14.

Oct. 13, 1950 [Nov. 25, 1949; June 30, 1950], No. 25072/50. Class 83 (ii). In a method of making internal combustion engine exhaust valves having a temperature and corrosion resistant reinforcement, the reinforcement is welded to a valve which has been preformed substantially to its final shape and the valve is then heated and forged in a die so as to mould the surface of the valve and the reinforcement, the surface being subsequently finished by machining. A forgeable reinforcing material is used, such as an alloy containing 60-80 per cent nickel and 15-20 per cent chromium and after welding the valve is heated to a temperature only slightly below the melting- point of the reinforcement material which thus become liquified under the pressure of the forging operation with the consequent elimination of pores or spongy spots. The reinforcement preferably covers the valve seating surface and also the outer peripheral surface.

[Class 40 (iv)] A connecting circuit between a two-way line 8, 9 and transmitting and receiving channels 7, 6 with echo-suppressors comprises impedances 10, 11 in said channels forming a bridge circuit in conjunction with the output and input impedances Ze, Zs of the channels, the line 8, 9 together with a series impedance 12 forming a diagonal. A balancing network is not used. An echo-suppressing relay 14 normally operated to short-circuit the receiving channel 6 is controlled by valve 13 biassed by resistances 18, 19 across which D.C. voltages are built up by rectifiers 16, 17 connected across impedance 12 and impedances 10, 11. Incoming speech over the line results in a D.C. voltage across resistance 18, but not over resistance 19 since A.C. voltage over impedances 10, 11 oppose each other. The valve is thus negatively biassed .and relay 14 falls back to open the receiving channel 6 and block the transmitting channel 7. Speech over the transmitting channel results in A.C. voltage across impedance 12 and also a resultant voltage across impedances 10, 11, the consequent D.C. voltage over resistance 19 being such as to balance the negative bias over resistance 18 or even to make the bias more positive than normal. As shown, microphone 2 and loud-speaker 3 are situated in a conference room 1. The channels 6, 7 may include wireless links.
