Title: Process for the manufacture of polymeric compounds which have functional end groups
IPC: C08F297/02
Filed: 1975-05-14
Abstract: 1498214 Divinylbenzene polymers BASF AG 14 May 1975 [10 June 1974] 20271/75 Heading C3P A polymeric compound containing any desired number of functional end groups is prepared by reacting together in an inert organic solvent in order (a) divinylbenzene either alone or in admixture with a monovinylaromatic compound (b) a low molecular weight organometallic consisting of an alkali metal and a C 1-50  organic radical and (c) a reactive low molecular weight compound; the content of divinylbenzene must not exceed 2À5% of the total reaction mixture, the molar ratio of divinylbenzene to alkali metal in (b) is 0À5-20 : 1, and the molar ratio of the alkali metal (in the polymeric, polyfunctional alkali metal complex formed by the reaction (a) + (b)) to (c) is #1 : 1. After the reaction of (a) and (b), the polymeric complex thus formed may optionally be reacted with an anionically polymerizable monomer. In the examples divinylbenzene (in admixture with either styrene or ethylvinylbenzene) is reacted in hydrocarbon solvent systems with n-butyllithium; the complex formed is then reacted with CH 2 Cl 2 , or CO 2  to provide polymers containing -Cl, and -CO 2 H groups respectively. In one case, the intermediate complex is reacted with more styrene, before being reacted with ethylene oxide to provide a polymer containing -OH groups.

Abstract: 687,595. Continuous casting machines. LAW, L. W. (Goss, N. P.). July 11, 1951 [Aug. 15, 1950], No. 20288/50. Class 83 (i). In continuously casting metal into a bottomless mould a starting bar is used which is formed at its upper end in such a way that splashing of the mould wall is avoided or reduced. The upper end of the starting bar 3 may have a recess 4 in which may be fitted a disc 5 connected to a rod 6 extending freely through the bar 3. When this emerges from the mould 1 it may be detached from the casting, e.g. by striking the rod 6. This may then be cut off and used with a new disc 5. The bar 3 may be of any desired cross-section and may be built up to leave cavities and thus reduce weight and unwanted conduction of heat. In a modification instead of a recess the bar 3 has a central projection, like a cone, with an inwardly curved wall.

Title: Improved method and means for absorbing shocks and vibrations in reciprocating-piston apparatus
IPC: F16F7/10
Filed: 1922-07-29
Abstract: 183,850. Babin, J. July 30, 1921, [Convention date]. Bed-plates, frames, &c. - Vibrations in fluidpressure engines and compressors are absorbed by freely mounting and so constructing them that they each produce a single series of rectilinear oscillations whereof each pair is equal in amplitude and duration. The centre of gravity of the moving masses is located upon the axis of the thrusts producing the oscillations so that the movement of the masses may be damped by fluid-pressure acting thereon. In the atmospheric motor, Fig. 1, during the forward movement of the piston 3 the driving gear is disengaged, a vacuum is created in the cylinder, and the piston and sliding cylinder brought to rest by atmospheric pressure. The gears 5, 6 are then engaged, and the inward power stroke effected. In the compressor, Fig. 2, the frame 20 is mounted on rollers 22, and the mass movements are damped by fluid compressed in cylinder 13. The compressor alternatively, may be suspended by links. Fig. 4 shows a mounting for a compressor of the kind described in Specification 183,849. [Class 122 (i), Engine and like cylinders &c.]. in which the casing is mounted between springs 38, and has plungers 36 mounted in cylinders 35 supplied with pressure air from the reservoir 33.

Abstract: 1,083,386. Vocoder pitch extractor; automatic tuning control. PHILCO-FORD CORPORATION. May 17, 1965 [May 15, 1964], No. 20865/65. Headings H3A and H4R. In a pitch extractor for a vocoder the speech signals are limited to a low-frequency band in band-pass filter 12 and applied to a non- linear circuit 14 which, by intermodulation, introduces the fundamental frequency which may have been absent due to the use of a carbon microphone or a transmission channel deficient at low frequencies. The intermodulated signal is then applied via a low-pass filter, e.g. cut off 300 c/s., to a band-pass filter 18 whose centre frequency and band width are controllable to track the pitch frequency. The output of the band-pass filter is then fed to a frequency discriminator which produces an analogue signal dependent on the pitch frequency. The analogue signal is converted to digital form in unit 24 from which digitals signals are available in either parallel, a shown, or serial form. The digital signals are applied to, e.g. a multiplexer and a transmission system for the vocoder, and to a store 28 which maintains the last known signal value during pauses in speech or during unvoiced sounds. The resulting digital signals are applied, via the digital to analogue converter 30, to control the centre frequency and band-width of the band-pass fiter 18 to ensure that the filter centre frequency stays tuned to the last known pitch frequency. The band-width of filter 18 is arranged to vary with the variation of centre frequency.
