Title: Improvements in or relating to copolymers and the process of making the same
IPC: C08G2/20
Filed: 1961-03-15
Abstract: High molecular weight copolymers of formaldehyde and acetaldehyde are prepared by reacting acetaldehyde and formaldehyde in a liquid anhydrous medium in the presence of a formaldehyde polymerization catalyst.  The liquid medium may be liquid acetaldehyde, with or without aliphatic or saturated cyclic hydrocarbons, particularly heptane, propane or pentane. Formaldehyde polymerization catalysts specified are tributylamine, cetyldimethylbenzylammonium bromide and diphenyl amine.  The process may be carried out in an atmosphere of nitrogen, between -78 DEG  and 0 DEG C.  The copolymer so prepared may be acylated, with for example, acetic anhydride in pyridine, to give better stability to the copolymer.  These copolymers are thermally stable, resilient, may be moulded, and are soluble in organic solvents; solvents specified are pyridine, dimethyl formamide, acetone and chloroform.  In the examples copolymers of formaldehyde and acetaldehydea are produced in the presence of (1) acetaldehyde and tributylamine, (2) heptane and tributylamine, (3) heptane and tributylamine, (4) acetaldehyde and cetyldimethyl-ammonium bromide, (8) propane, diphenyl amine and tributylamine, (10) pentane and tributylamine.  In Examples (1) and (12), the copolymer produced is dissolved in pyridine and acetylated by treatment with acetic anhydride.

Abstract: 368,095. Coke ovens. MUELLER, W., 8A, Niederwallstrasse, Gleiwitz, Germany. March 30, 1931, No. 9560. [Class 51 (ii).] In a coke oven having vertical flues which are alternately fired from top and bottom the connections are such that upflow and downflow heating- walls alternate along the length of the battery. In the oven shown which is adapted for heating either by rich or lean gas, the two regenerators 3, 4, or 3a, 4a beneath each oven are connected to the lower ends of the flues 7 of the heating-wall on one side by ports 23, 24, and to the upper ends of the flues of the heating-wall on the other side by passages 25, 10, and 26, 11, the passages 10, 11 being formed in the partition walls between the vertical heating-flues. When operating with lean gas, and in the phase indicated by the arrows, gas is supplied to the regenerators 3 from the mains D, and air to the regenerators 4. Combustion is effected upwards in the two outer heating-walls shown, and downwards in the middle wall, and the waste gases pass off through the regenerators 3a, 4a. When operating with rich gas which is admitted through upper nozzles 16 and lower nozzles, supplied either from horizontal or vertical conduits 9a, X, all the regenerators are used for preheating air. An oven adapted for heating by rich gas is also described.

Abstract: 823,570. Voltage measurement. BRISTOL CO. March 25, 1957, No. 9662/57. Class 37. [Also in Group XXXV] Apparatus for measuring the e.m.f. of a source (e.g. a thermocouple) and including a transformer 13 (see Group XXXV) comprises a bridge network 10 wherein a slide wire 16 is energized from a constant potential battery 17 and a tapped point 21 on a resistor parallel to the slide wire is connected to one terminal of a source 24. The other terminal is connected through a reversing switch 12 to a slidable contact 19. The switch 12 is essentially a pair of single-pole double-throw switches with interconnected fixed contacts and movable contacts 33, 36 on an armature 37 which oscillates at mains frequency on energization of a coil 38. The movable contacts are connected through a double screened cable 60 to the primary of the transformer 13 which is thus energized by the differential potential difference and alternates at mains frequency. The output of the secondary winding of the transformer is amplified through an amplifier 14 as described in Specification 736,742, [Group XXXV], and applied to one phase of a two-phase induction motor the other phase being supplied by mains supply. The motor drives to the balanced position the slidable contact 19 which is associated with a measurement scale. Specifications 686,890 and 703,772, [Group XXXV], also are referred to.

Abstract: 735,915. Measuring bridges; transfer impedance and admittance measurements. WAYNE KERR LABORATORIES, Ltd., and CALVERT, R. April 2, 1954 [April 10, 1953], No. 9762/53. Class 37. In an A.C. bridge circuit for measuring the transfer admittance of a network given by I=YE where Y is the required admittance, E the input voltage and I the output current at fixed or variable frequencies, an A.C. energized input transformer 10 has a variably tapped secondary 12 energizing the unknown network 15 whose output current energizes the variably tapped primary 17 of output transformer 18; and also a variably tapped secondary 23 which is connected directly to an intermediately variable tap 21 of a second primary 22 of transformer 18, and also connected to a standard variable resistance 24 and a standard variable capacitance 25 the free ends of which are selectively connectible over switches 26, 27 to either end of the primary 22. The secondary of transformer 18 is connected to an unbalance detector and the standard variables are adjusted separately until the output is zero, when the transfer admittance of the network is equivalent to the transfer admittance of the standard variables combined with regard to the phase quadrant in which each is connected by switches 26, 27, multiplied by a factor dependent on the tapping positions of windings 12, 17 and 13, 22. The standard variable capacitance is replaceable by a corresponding variable inductance switched in phase opposition thereto, and the system is applicable to the determination of transfer impedance by energizing winding 17 not from the output current of the unknown network but from the current flowing thereto from winding 12.

Abstract: 1450989 Pulse density modulation; quantizing STANDARD TELEPHONES & CABLES Ltd 5 March 1974 9770/74 Headings H3H and H3T In an arrangement for modulating pulse density or mark : space ratio in accordance with an anologue input, and providing a "digitised" output, the input is applied to an amplifier A whose output is connected to a conditioning input D of a trigger circuit DQ/Q to which clock signals fc are applied. The output signals from the arrangement appear at the complementary output Q of the trigger circuit and are fed back via an integrating circuit R 1 C 1  to the conditioning input of the trigger. In the absence of an input, the arrangement produces output pulses having unity mark : space ratio, as the integrated value of an output signal of one polarity, fed back to the conditioninginput of the trigger, eventually causes the trigger to switch. The analogue input effectively provides a bias, causing the mark : space ratio of the binary stream at the trigger circuit output to alter, alterations being in discrete steps. In the arrangement of the invention, a further integrating circuit R3C2 is provided from the complementary output Q to the input of the amplifier A, in order to improve the dynamic range of the arrangement. A further integrating circuit R6C3 may be provided as shown in Fig. 8 between the normal output Q of the trigger circuit and a second input of the amplifier to provide automatic biassing so that inputs offset from zero can be handled. Such a bias may alternatively be provided by a D.C. source.

Abstract: 693,363. Core takers. CONSOLIDATED AFRICAN SELECTION TRUST, Ltd., and BROWN, H. F. April 2, 1951 [April 20, 1950], No. 9790/50. Class 85 An earth boring tool for core sampling comprises a drill tube 14 to the lower end of which is secured a drill ,bit 18 and a coaxially disposed cylindrical bucket 11 the lower end of which extends below its base 12 to a level below that of the drill bit 18 and is provided with cutters 19. The displaced soil enters the cutter - toothed mouth 21 of a riser pipe 20 which conveys it upwards through the base of said cylinder to dump it therein. The soil is carried up the riser pipe by being entrained in water which fills the bottom of the borehole and which is urged up said riser pipe by air under pressure emerging from nozzles 31. This air pressure is supplied down the tube 14 and passes to the nozzles through a separator 26. When the borehole is dry, a quantity of water is also supplied down the pipe 14, passing into the borehole by a passage 32 in the bit. During the operation the water is recirculated, either escaping from the cylinder 11 by spilling over the upper edge thereof, or through a valve 40, 41, 42. If a casing is used simultaneously with the boring tool, both are rotated from a common rotary table at differing speeds, whilst brake shoes are provided in the table for gripping the lower section whilst the table makes or breaks the joint with the section above.
