Patent GB-1272769-A (GB)
Title: Improvements in or relating to cephalosporin derivatives
Inventor: GILBERT DAVID ARTHUR
IPC: C07D501/20
Filed: 1968-08-02
Abstract: 1,272,769. Enzymic production of carboxyalkyl-cephalosporins. GLAXO LABORATORIES Ltd. 18 July, 1969 [2 Aug., 1968], No. 37113/68. Heading C2A. [Also in Division C3] Novel cephalosporin derivatives having the Formula I and salts thereof, wherein R is -CO.COOH or -COOH and X is an acetate group, a residue of a nucleophile, -OH or hydrogen, are prepared by treating cephalosporin C or a salt or derivative thereof wherein X is as before with a fungal D-amino-acid oxidase under aerobic conditions, catalase activity being present when the group R in the desired product is -CO.COOH. The oxidase may be derived from species of Aspergillas, Penicillium, Neurospora or Aerobacter or the yeast Trigonopsis variabilis, and is prepared as an acetone powder or cell-free extract of the mycelium (see Division C3). Oxidase formation may be induced in the fungus by adding a D- or DL-amino-acid (e.g. DL-alanine, DL-valine or methionine) to the growing cells at the seed stage. The oxidase preparations normally contain some catalase but extra catalase may be added if required. The presence of catalase prevents oxidative decarboxylation via an intermediate wherein R is -CHO and hence R is -CO.COOH in the product. By inhibiting the catalase (e.g. with ascorbic acid, 3-amino-1,2,3-triazole or an inorganic azide) or using a catalase-free aminoacid oxidase preparation, this oxidative decarboxylation is allowed to proceed resulting in a product wherein R is -COOH. The cephalosporin C starting material may be a preferably de-proteinized fermentation broth or a semisynthetic material having the aforesaid substituent X in the 3-position. The product may be isolated by solvent-extraction or by use of ion-exchangers and optionally converted to the 2,4-dinitrophenylhydrazone derivative. The products are useful as intermediates for preparing the corresponding 7-ACA derivatives by N-deacylation.

Title: Improvements in or relating to the Production of Thermoplastic Synthetic Resin Film.
Inventor: SVOBODA JIRI
IPC: B29C48/305
Filed: 1968-08-05
Abstract: 1,177,459. Flat films having parallel striations; extrusion dies. REIFENHAUSER K.G. 5 Aug., 1968 [7 Aug., 1967], No. 37202/68. Headings B5A and B5B. An apparatus for extruding thermoplastic synthetic organic polymeric material to form flat film comprises a screw extruder provided with an extrusion die having an elongated slot extrusion orifice characterized in that each of the lips of the extrusion orifice, instead of being plain, is provided with a row of projections directed towards the opposite lip, the height of the projections being about  to 1/3 the distance between the lips of the extrusion orifice. As shown in Figs. 1 and 2, a film 1 is melt extruded through the slot-shaped extrusion orifice 6 having a width 5 of an extrusion die 4, the molten film material being forced through the die by the screw extruder 2, 3. As shown in Figs. 2 and 3, the lips of the extrusion orifice 6 are serrated, so that projections 7 and 8 project from the lips of the die orifice towards one another and form grooves in the film, the overall thickness of which is determined by the dimension 5. Owing to surface tension effects acting on the still molten film immediately after it leaves the die, the grooves formed on both surfaces of the freshly formed film largely disappear, but the final solidified film nevertheless has parallel longitudinal striations on both surfaces. As shown in Fig. 3, the projections 7 and 8 are of sawtooth form, but alternatively they may be sinusoidal. The projections 7 and 8 may have sloping rear faces 11, the height of the projections thus increases from zero to a maximum at the outlet of the extrusion duet where the film leaves the extrusion head. The projections 7 and 8 may be formed along the opposing edges of a pair of members 12 and 13, detachably mounted on the face of the die parallel to the length of the extrusion slot, the opposing edges of the members constituting the lips of the die.

Again, the member 20 may be directly connected to the slab by a clip having spring fingers or rigid flanges to engage the grooves therein, such clips having 'tongues of flanges to locate same on the member 20, see Figs. 6-13, (not shown).
Patent GB-1529758-A (GB)
Title: Vf signal receiver
IPC: H04Q1/457
Filed: 1976-09-09
Abstract: The signal receiver is intended to identify the end of a signal as soon as possible and on the other hand not to separate the signal in the event of signal interruption due to interference. For these purposes, a monostable trigger circuit (MK) is used whose self-holding period corresponds to the duration of the longest interference and the duration of at least one measurement which follows the main test once the presence of a signal has been identified; provided that the half-period results and preliminary test results are positive, a trigger signal is transmitted, with each zero passage of the AC input voltage, to the trigger circuit which is held thereby and which interrupts the signal receiver output signal only when it is released. <IMAGE>
