Title: Copolymers of vinylidene chloride and acrylic esters and an application thereof
Inventor: ELGOOD BRIAN GEORGE
IPC: C08F214/08
Filed: 1965-09-23
Abstract: Copolymers of 40-75% molar vinylidene chloride and 60-25% acrylic ester are prepared by emulsion polymerization using "delayed addition" technique; less than 20% of the monomers is added initially and the remainder added over a period exceeding one hour.  The surface-active agent may also be added step-wise. In some examples a small amount of acrylamide with or without acrylic acid is also present and in another a mixture of two esters, methyl and butyl acrylates, is used.  Sodium persulphate and sodium metabisulphite are used as catalyst.  The polymer emulsion is used for coating and a paint composition exemplified also contains titanium dioxide, tetrasodium pyrophosphate and polyvinylalcohol.

Title: Improvements in radio systems with means for processing demodulated signals
IPC: G01S13/78
Filed: 1966-09-15
Abstract: 1,146,875. Secondary radar. COMPAGNIE FRANCAISE THOMSON HOUSTONHOTCHKISS BRANDT. 15 Sept., 1966 [15 Sept., 1965], No. 41344/66. Heading H4D. In a secondary radar system, wherein a response signal may be received at the interrogating receiver both directly and after reflection, said reflected signal is removed to enable accurate distance measurements. The interrogation, and response signals are frequency shift keyed signals modulated according to a desired binary code between frequencies f1 and f2. The response signals are received at the interrogator, Fig. 1, and a frequency discriminator 16 produces for a frequency shift from f1 to f2, outputs as shown in Fig. 2. In waveform 20, the direct signal d is very much larger than   the reflected signal r, in waveform 21, r/d = 0À1, in waveform 22, r/d = 0.5 and in waveform 23,   r/d = 0.9. The position of the direct signal thus becomes increasingly obscure as the reflected signal increases. The rapid fluctuations are removed by a low-pass filter 17 to produce corresponding waveforms of Fig. 3. The waveform of Fig. 3, (33), is shown in full at 43, Fig. 4. Waveform 43 is differentiated in means 18 (waveform 44) and also peak clipped (waveform 45). Waveform 45 is fed to a logic circuit 19 which produces a pulse 46 having a first step coincident with the first positive pulse in waveform 45, and a second step coincident with the first negative pulse. Pulse 46 corresponds to the direct received signal and enables accurate distance measurements to be made. Logic circuit 19 comprises, Fig. 5, a bi-stable circuit 54 triggered at both stage inputs 55 and 56 by positive pulses, diode 51 to pass positive pulses in waveform 45, and diode 52 to pass negative pulses in waveform 45, an inverter converting these passed pulses to positive triggering pulses. Thus, once circuit 54 has been set in its upper state by the first positive pulse, further positive pulses have an effect, and the first negative pulse, via inverter 53, returns it to its lower state.

[Also in Divisions H3 and H4] In R.F. heating equipment (see Divisions H3 and H4), oscillations generated in a cavity resonator 1, Fig. 3, are extracted by means of a pick-up loop 2 which is connected at one end to the cavity wall and at the other to a feedthrough capacitor. The feed-through capacitor comprises outer plates 6, Fig. 1, and an inner plate 7 which are separated by solid dielectric material; the loop 2 is at one end attached to the lower plate 6 and at the other passes through an aperture in this plate and is attached to plate 7. An output connection 8 is attached to plate 7 passing through an aperture in the upper plate 6. The inductance of loop 2 is resonated with the capacitor of the feedthrough capacitor to remove harmonics from the output, the resonance frequency being preferably below the fundamental frequency of oscillation. The pick-up of harmonics is further reduced by surrounding the loop 2 with a screen comprising outer plates 3, 5 and an inner plate 4, separated by air or solid dielectric material; the capacity between the plates is resonated with the self-inductance, preferably at a frequency between that of the fundamental and of the second harmonic. The screen is made considerably longer than the pick-up loop (Fig. 2, not shown). The output connection 8 terminates at the first of two capacitor plates 13, 14, Fig. 3, arranged on either side of a screen 15 in an output compartment 12, being separated from it by layers 16, 17 of dielectric material, plates 13, 14 being connected together by means of a conductive stub 18 passing through a clearance hole in screen 15. A further suppression of harmonics is achieved by resonating the inductance of lead 8 with the capacity provided by plates 13, 14, 15, at a frequency below the fundamental frequency, but above the resonant frequency of coil 2 and capacitor 6, 7. Additional attenuation of the second and third harmonics may be obtained by connection of circuits resonant to these frequencies, between the plate 13 and screening case 12. It is stated that the system of plates 6, 7 may be replaced by a. single plate forming a lining to the cavity 1, the wall of which then constitutes the other plate: a number of pick-up coils may be used, distributed around the cavity lining.

The fin-like elements 11 are preferably triangularsection rods, e.g. of wood, metal or plastic, which taper to an angular pressing edge, and are linked together, e.g. by chains 12, to form an endless belt which is driven by a roller 9 and guided by rollers 7, 8 so that the lower rim 10 conforms in its path to substantially that followed by the loop-forming rods 4, 4<SP>1</SP> and is preferably least spaced from the drum 2 at a point mid-way between the rollers 7, 8. The elements 11, which may be of different sizes, embody slots (Fig. 2) to engage depresser members 13 extending between the rim 10 and drum 2 and acting as guides, and at their ends have bearer members 24 to push the loop-forming rods together to prevent the loops from being pulled out by friction when they are disengaged from the elements 11 adjacent the roller 8.

[Also in Division H3] A magnetic storage array (see Division H3) is constructed by forming sheets of green ferrite by doctor blading a ferrite slurry on a support, drying and peeling off the resulting flexible sheets, depositing different patterns of conductors on to different surfaces of the sheets, assembling the sheets into a laminated stack, and applying heat to produce a sintered ferrite sheet having conductors embedded therein. The ferrite slurry comprises 65 parts (by weight) of a calcinated ferrite made of zinc, magnesium and manganese oxides, 13 parts of an organic binder and 52 parts of a methyl ethyl ketone solvent. Before sintering, the stack is formed into a laminated green ferrite sheet by applying pressure of about 900 lb. per square inch and heating for about 10 minutes at 120‹ C. A sintering temperature of about 1200‹ C. is used, the conductor being formed of higher melting point material such as palladium, rhodium or platinum so as to be unaffected by the sintering process. After sintering, the resulting sheet is air quenched at room temperature or annealed in nitrogen at 1100‹ C. for 1 hour. A typical arrangement of deposited conductors 12, 14, 18 and 22 on green ferrite sheets 16, 20, 26 is shown in Fig. 2, the upper conductors being covered by a plain green ferrite sheet 10. Other conductor dispositions are described, and in one embodiment conductors are deposited on opposite sides of a single sheet and only partially covered by using plain green ferrite strips, Figs. 7-9 (not shown). The conductors are formed by vacuum deposition through a mask, followed by electrolytic deposition to a substantial depth. To enable the conductors to withstand ferrite shrinkage during the sintering process, the conductors are formed with a coarse or spongy texture which is imparted by using a relatively high electroplating current such as 1 to 5 amperes per square foot of conductor surface.
