Abstract: 1,232,528. Treating I. C. engine charges. FORD MOTOR CO Ltd. Sept. 5, 1969 [Oct. 7, 1968], No.43980/69. Heading F1B. [Also in Division F2] The inlet 16 of an air cleaner 10 contains a valve 22 which controls the flow of ambient temperature air from an inlet 24 and hot air from a duct 18. The duct 18 contains carbon adsorbent 38 and has conduits for leading fuel vapour from the fuel tank and carburetter float chamber to the adsorbent. The valve 22 is operable by a vacuum motor 30 to close the duct 18 when the intake manifold vacuum is insufficient to prevent a spring in the motor from acting against the valve extension 34. A thermally responsive member 32 moves the valve 22 with increasing temperature towards a position closing the duct 18. The motor 30 overrides the member 32. A bi-metallic butterfly valve (46), Fig. 1 (not shown), in the upstream end of the duct 18, adjacent a shield (20) directing air flowing to the duct over the exhaust manifold, closes the duct when a predetermined air temperature is exceeded.

Abstract: 1305715 Stabilized polymer dispersions; modified polyamides and polyesters IMPERIAL CHEMICAL INDUSTRIES Ltd 26 June 1970 [4 July 1969] 33871/69 Headings C3P and C3R Coating compositions are based on a dispersion of particles of a thermoplastic non-crosslinkable polymer in an organic liquid, stabilized by a stabilizer containing cross-linkable reactive groups, the organic liquid containing a crosslinking agent for the reactive groups of the stabilizer, so that the latter is cross-linked on application of the composition. If the composition contains particulate pigment, this may also be stabilized in a similar manner. Preferred non-crosslinkable polymers contain at least 75% of methyl methacrylate units. In examples non- aqueous dispersions of polymethyl-methacrylate, poly-(methylmethacrylate / ethylacrylate), poly - (methylmethacrylate / methacrylic acid), polyvinyl acetate, and poly-(methylmethacrylate/butyl acrylate), are prepared by polymerization of the monomers in the presence of one or more cross-linkable stabilizers. A stabilized dispersion of polyvinyl chloride is prepared, however, by mixing P.V.C. powder with the stabilizer and other standard ingredients. In all the examples the cross-linking agent for the stabilizers (in which the cross-linkable reactive group is OH), is a butylated melamine/formaldehyde resin. The stabilizers used contain crosslinkable hydroxy groups and are prepared as follows: (1) a carboxyl terminated hydroxyl group-containing polyester is prepared from 12- hydroxy-stearic acid and dimethylolpropionic acid. The terminal carboxyl group is then esterified with glycidyl methacrylate, and the resulting terminal olefinic group copolymerized with methyl methacrylate and methacrylic acid ; (2) as above but copolymerizing the modified polyester with methylmethacrylate and glycidyl methacrylate (this particular stabilizer is used to stabilize pigments used in the composition); (3) as above in (1) but using methyl methacrylate, hydroxypropyl methacrylate and methacrylic acid as comonomers with the modified polyester; (4) by addition polymerizing lauryl methacrylate, hydroxyethyl methacrylate and glycidyl methacrylate, and reacting the glycidyl groups with methacrylic acid; (5), as (1) but copolymerizing the modified polyester with methyl methacrylate, ethyl acrylate and dimethyl aminoethyl methacrylate and quaternizing the t-amino groups with benzyl chloride and (6) (Example 8) preparing a polyesteramide from 12-hydroxystearic acid and #-amino undecanoic acid, reacting residual carboxyl groups with glycidyl methacrylate, and then copolymerizing with methyl methacrylate and methacrylic acid (the cross-linkable reactive groups in this case are substituted amide groups, also cross-linked with melamine formaldehyde resin). Compositions are prepared from the stabilized polymer dispersions.

Abstract: 1316113 Correcting data transmission errors; telegraphy MARCONI CO Ltd 20 Aug 1970 [25 Sept 1969] 47377/69 Headings H4P and H4R In a transmission system in which a number of digital signals are transmitted as modulation of respective carriers, a known probe signal is transmitted over the system, and received at the receiver, the resulting digital signal, corresponding to the received probe signal, is compared with the known probe signal to determine digital difference signals which are stored and used to modify subsequent signals. As described the carriers are phase modulated each of four possible phase positions, 0, 90, 180, 270, representing one possible dibit, i.e. " 00 ", " 01 ", " 10 ", " 11 ". The probe signal may comprise the transmission of the dibit " 00 " on each carrier. The carriers are interpreted at the receiver and the resulting dibits stored for subtraction from the following signals, after interpretation in digital form. The subtraction may be carried out by mod 2 adding and effecting a correction to take into account " carry " information. In the system where increasing phase shift corresponds to increasing digital values the correction can be effected by adding a dibit " 10 " where the error signal has a " 1 " as its second digit and the information signal received has a " 0 " as its second digit. The correction can be implemented by feeding the mod 2 sum of the received signal and error signal direct to an input of an exclusive or gate and via a one digit delay to the other input, the output is then the corrected signal. The probe signal may be transmitted periodically to check the correct functioning of the system. The phase of the probe signal may be varied cyclically over a predetermined range and if the variation causes a change in the digital interpretation a fixed phase delay may be inserted in the channel to provide a margin of error in the interpretation of the received signals.
