Title: Polymeric carrier for a controlled synthesis of polypeptides and the method of its preparation
IPC: C08F8/24
Filed: 1973-11-06
Abstract: 1409930 Polymeric carriers for use in polypeptide synthesis CESKOSLOVENSKA AKADEMIE VED 6 Nov 1973 [6 Nov 1972] 51468/73 Headings C3H and C3P Carriers for use in polypeptide synthesis are prepared by chloromethylation (with formaldehyde and hydrogen chloride) of an acrylate or methacrylate gel copolymer containing hydrophilic functional groups and also aromatic rings. The aromatic rings may be present in a comonomer or may be introduced by an aftertreatment. In the former case, the polymer to be chloromethylated comprises units of (a) a hydrophilic monomer, e.g. 2 - hydroxyethylmethacrylate, 2-hydroxyethyl acrylate, acrylamide, methacrylamide, N-methyl methacrylamide, 2-aminoethyl acrylate, or 2-aminoethyl methacrylate; (b) a cross-linking monomer, e.g. ethylene glycol di-acrylate or di-methacrylate, tetraethylene glycol dimethacrylate, methacroylated pentaerythritol, methylene-bisacrylamide or divinyl benzene; and (c) an aromatic monomer, e.g. acrylanilide, methacrylanilide, phenyl acrylate, phenoxyethyl methacrylate or styrene. In the latter case, examples are given in which the polymer to be chloromethylated is obtained either by reacting a 2- hydroxyethyl methacrylate/ethylene glycol dimethacrylate copolymer with benzoyl chloride, phenyl isocyanate or diphenyl dichlorosilane; or by subjecting a 2-hydroxyethyl methacrylate/ ethylene glycol dimethacrylate/p-acetaminophenoxyethyl methacrylate to sequential hydrolysis, diazotization and coupling with #- naphthol. Polypeptides are synthesized on the above carriers by a sequential reaction procedure using different amino-acids which may contain protective end-groups. Examples are given in which first glycine and then alanine are built on to one of the above carriers and the resulting polypeptide chain then split off.

Filed: 1971-11-09
Abstract: 1366365 Radio signalling LICENTIA PATENT - VERWALTUNGS - GmbH 9 Nov 1971 51908/71 Heading H4L In a system for reducing echo distortion at the receiver in a frequency modulation radio link, at the transmitter the frequency-modulated signal y 0  is additionally phase-modulated by a frequency-wobbled pilot signal Z(t) by multiplying at # 1  the pilot signal Z(t) with the frequency-modulated signal y 0  phase-shifted by 90 degrees and adding the resultant signal to the signal y 0  to provide a signal y 1 . At the receiver the distortion is removed by combining with the received signal y 1  several artificially produced echoes, in networks N 1 , N 2  &c., the different delays being produced by lines L1, L2, &c. controlled by resistive terminations R1, R2 &c. The pilot signal is selected via frequency demodulator FD, bandpass filter BP and integrator I, and amplitude modulation due to the echo distortion is detected at G1 and supplied via a high pass filter HP to a rectifier G2. The resulting voltage v controls an optimizer to adjust the mismatches of the lines L1, L2 &c. to produce the desired correction to reduce the voltage v to a minimum. The pilot signal at the output of integrator I is also supplied via an amplitude and phase correcting filter BP<SP>-1</SP> to a phase modulator #/2 where it is combined with the frequency-modulated signal phase-shifted by 90 degrees, the resultant signal being subtracted from the frequency-modulated signal to remove the pilot modulation.

Title: Centrifugal casting method and apparatus
IPC: B29C41/36
Filed: 1965-12-21
Abstract: 1,128,608. Moulding tyres. DUNLOP CO. Ltd. 21 Dec., 1965 [31 Dec., 1964], No. 54223/65. Heading B5A. Tyres are centrifugally cast in a rotatable mould 13a, 13b within which is located an inflatable core 26; moulding material is fed to the space between the core and mould from hoppers 41 containing materials of different physical properties, so that by varying the material fed to the mould space a tyre is produced of material having properties which vary from one region to another. For example, a material which has been centrifuged to form the tyre crown can be left to harden before different materials are fed to the mould to be centrifuged at different speeds with the core inflated to different pressures to form different parts of the tyre sidewall. Tyre bead inserts are placed within the mould space before the mould is brought to the casting station. Alternatively, a tyre carcass with its bead rings in position may be treated in the mould before the casting operation. A circular mould tube 12 rotates about a pedestal 11 and supports a circumferentially spaced set of moulds 13 which are brought in turn to a casting station where the mould is charged. Each mould lower half 13b is secured to a disc 14 rotated by a motor 16 having a drive wheel 15 which, by pivoting the motor, can be brought into and out of engagement with the disc. A cylinder 21 depending and integral with the disc accommodates a piston 22 which carries a bush 23 clamped between the mould halves and attached to the upper bead (27), Fig. 3, (not shown), of the inflatable core. The lower bead of the core is clamped between rings attached to the lower mould half. When the upper mould half is removed and the piston 22 raised the core is axially extended. Pressurizing fluid is supplied to the core through passageway 56 from the cylinder 21, and moulding material is supplied to the mould space through a vertically adjustable nozzle 32, which seals within a recess in the bush 23, and passage (51-55). Each hopper supplies a separate metering device 40 comprising a chamber 42 and a fluid pressure operated ram 43 which forces material to a main cylinder 33 from which the material is forced by a piston 46 extending from a ram 47. In passing to the main cylinder the material is heated in plasticizing passages 45.

As shown, the sensing means comprises a U-shaped bracket 34 carrying on one limb two nozzles 38 and on the opposite limb associated detectors in the form of pitot tubes 36, each detector sensing the jet issuing from the respective nozzle 38 when the jet is not interrupted by the intervening web 10. Each tube 36 is connected to a pressureactuated switch or valve which is employed to  actuate the slewing mechanism. In another embodiment Fig. 4, (not shown) each detector consists of a cup, on which the jet impinges when not interrupted, secured to the outer end of a spring-counterbalanced hinged lever which is arranged to operate a micro-switch to control the slewing mechanism. To economize on fluid consumption the jets may be operated intermittently e.g. 5 seconds on and 25 seconds off, so long as the web continues to run on its normal track, this intermittent operation being superseded by continuous operation when corrective guiding action is initiated; suitable timing arrangements for this purpose are described with reference to Figs. 6 to 8 (not shown). The guide roller and associated slewing mechanism Figs. 1 to 3, (not shown) may be of the type described in Specification 899001.

Abstract: 1492186 Holographic data storage; holographic data reader THOMSON-CSF 17 Dec 1974 [18 Dec 1973] 54559/74 Headings G4A and G4M A digitally encoded signal train, Fig. 1, is, before being recorded holographically, split up into portions of duration NMT comprising N groups each of M bits by a gating circuit given in Fig. 3 (not shown) controlled by a clock 30, Fig. 4 producing clock pulses of period T, the groups of bits being conveyed to N channels V 1 -V n  via delay lines (L 1 )-(L n-1 ) so that the signals on all the channels are in phase, each group of M bits, e.g. from channel V t , being simultaneously recorded as M superimposed holograms, e.g. H i , on a track of a photographic film 42. The holograms H 1 -H n  are produced by means of a laser 40, object beams Q 1 -Q n  passing through optical modulators 41 controlled by signals from channels V 1 -V n , and a reference beam 15, being directed on to the photographic film 42. The M superimposed holograms of a group may be distinguished from each other by shifting the wavelength of the (variable-wavelength) laser 40 between the recording of each hologram of that group by means of a coder 33 driven by the clock 30. Alternatively, a fixed-wavelength laser may be used and the holograms distinguished from each other by varying the angular direction of the reference beam 15, this being accomplished by means of an electro-acoustic light deflector (50), Fig. 5 (not shown) driven by the clock 30 via a coder (53). The holograms are read from the film, following photographic development in the apparatus of Fig. 8 (not shown) by means of the detection of transmitted beams (J 1 )-(J m ) from the M bits of each group by N groups of photodiodes (D 1 )-(D m ), Fig. 6 (not shown). The outputs of the photodiodes (D 1 )-(D m ) are fed to an adder circuit (72), Fig. 7 (not shown) controlled by the clock 30 via a coder (70), to reconstruct the signal train. In a modification, Fig. 9 (not shown) each group of M bits is timeexpanded to a duration at most equal to NMT prior to being recorded as superimposed holograms, the bit duration proper also being expanded. A further slight modification of Fig. 9 is described wherein the clock 30 is replaced by a clock of periodicity MT. The photographic film may be replaced by a ferroelectric crystal or a ferroelectric ceramic, an amorphous semiconductor or a photothermoplast (a carrier formed of alternate photoconductive and thermoplastic layers).
