Title: Cephalosporin intermediates and process therefor
IPC: C07D501/04
Filed: 1974-11-04
Abstract: 1439890 7-Oxocephalosporins SMITHKLINE CORP 4 Nov 1974 [8 Nov 1973] 47664/74 Heading C2C Novel compounds of the formula where A is H, C 2-3  alkanoyloxy, C 1-4  alkoxy, C 1-4  alkylthio, or SHet and Het is tetrazolyl, thiadiazolyl, oxadiazolyl, triazolyl, diazolyl, pyridyl, pyrimidyl, or pyrazinyl, each Het being unsubstituted or substituted with one or two C 1-6  alkyl groups, and M is hydrogen or an easily removable ester protecting group, may be prepared by (1) treating an aminomethylthio compound of the Formula (II) with metal salt which will co-ordinate with the sulphur and assist in <SP>À</SP>breaking the carbonsulphur bond in a water-containing watermiscible organic solvent, or (2) treating a mineral acid salt of said aminomethyl-thio compound with a water-containing watermiscible organic solvent. The 7-oxocephalosporins of Formula (I) are useful for preparing novel cephalosporins. Treatment of 7-oxocephalosporanic acid esters with a phenoxyacetylmethylenetriphenylphosphorane gives 7- phenoxyacetylmethylenecephalosporanic acid esters. Catalytic hydrogenation of the methylene double bond with Pt or Pd catalysts followed by cleavage of any ester protecting group gives 7# - phenoxyacetylmethylcephalosporins which are antibacterial agents. Reduction of 7-oxocephalosporins gives 7-hydroxycephalosporins which can be acylated with known acyl groups, e.g. phenoxyacetyl chloride yielding 7#-phenyloxyacetoxycephalosporanic acid. As intermediates, t-butyl deacetoxycephalosporanate is treated with benzaldehyde forming t - butyl 7# - benzylideneaminodeacetoxycephalosporanate which is reacted with sodium hydride and methyl methanethiosulphate to form the 7α - methylthio derivative; treat. treatment of the latter with HC1 yields the hydrochloride salt of t-butyl 7#-amino-7α- methylthiodeacetoxycephalosporanate from which the free base is obtained by treatment with NaHC0 3 ; t-butyl 7#-aminocephalosporanate is similarly converted to t-butyl 7#- benzylidene - aminocephalosporanate, the 7α-methylthio compound and finally the HCl salt and free base of t-butyl 7#-amino-7α-methylthiocephalosporanate.

Abstract: 1,121,493. Bookbinding. LEIPZIGER BUCHBINDEREIMASCHINENWERKE, VEB. 12 Nov., 1965, No. 48216/65. Headings B6A and B6P. Book signatures 10 are subjected to pressure along or adjacent to their binding edge by rollers such as rollers 11, 12, Fig. 4 to which are applied ultrasonic vibrations, the effect being to cause the fibres of the paper to felt into one another along the pressure areas so as to produce relatively thin reinforced parts along those areas. Various-shaped binding edges (Figs. 1b, 1c 1d) may be formed according to the profile of the rollers. The thinner parts may be separated along the binding edges by normal thickness parts if the rollers are vibrated intermittently as the signature passes between them. A number of signatures treated as described are formed into a book (Figs. 7, 8) by embedding the binding edges in adhesive (18, 25) and applying a sleeve (19), a spine (20), end papers (22) or slip strips (27) and covers (21, 26).

Title: Method and apparatus for controlling the level of metal in a continuous casting mould
IPC: B22D11/20
Filed: 1973-10-16
Abstract: 1449846 Continuous casting CONCAST AG and SCHLOEMANN AG 16 Oct 1973 [17 Oct 1972] 48239/73 Heading B3F [Also in Division G3] In a method of controlling the level of the pool of molten metal 35 in the mould 4 of a continuous casting plant, a detector 5, 6 provides a signal of the actual level for comparison by comparator 13 with a reference signal from 15, a resultant error signal being used to control the flow of metal into the mould, e.g. by adjusting the stopper 3 of a tundish 1, and also being fed via line 20 to a function generator 28 which supplies a speed reference signal to a loop which controls the speed of withdrawal of the incipient casting 7 from the mould, the withdrawal speed reference signal being thereby modified if the rate of change of the level error signal exceeds a preset value. As shown, the withdrawal speed control loop comprises a-motor 24 driving rolls 9 and a tachogenerator 23 providing a feedback signal to a regulator 22. The function generator 28 receives a reference signal from 29 to set the withdrawal speed under normal operating conditions. The signal from the level detector, which is of radio-active type, is also fed to the generator 28 via a line 48 and, if the level reaches a maximum or minimum permitted value, the withdrawal speed reference signal is modified irrespective of the rate of change of the level error signal. The generator 28 includes a feedback unit (43, Fig. 2, not shown) whereby its output on line 31 is compared with its input from the reference source 29. The feedback unit attempts to restore the actual speed reference signal to the desired value from 29 after a time delay to allow the pool level to be restored to its proper value.
