Title: Method of and apparatus for producing crystalline material
Inventor: TENEN GEORGE GRAHAM
IPC: B01D9/00
Filed: 1963-02-25
Abstract: <PICT:0988553/C1/1> Sodium carbonate decahydrate is crystallized from solution in a polythene container floating in a liquid cooling medium.  A number of the containers, single or in groups, are passed in series to a crystal discharge station.  Passage may be effected by a horizontally acting pneumatic or hydraulic ram.  The containers may be passed at a rate of 8 in./min.  The containers may each remain up to 24 hours in the cooling medium.  The containers may be of inverted truncated pyramid form (Fig. 2, not shown) and contain such an amount of solution that they are inwardly flexed while floating in the cooling medium.  As shown, lines of eight containers held together by a wooden frame 8 pass in succession in a line A under the action of a ram 14 after passing from a combined discharging and charging station 9 (Figs. 6 and 7, not shown) under the action of a ram 13.  On nearing the far end of line A, each group of containers is separated from the rest by a ram 15 and transferred by a ram 16 to a line B of groups of containers.  On nearing the far end of line B, each group of containers is separated from the rest by a ram 12 and passed to station 9.  The discharged crystals are removed on a conveyer belt 10.  Cooling medium is passed to vessel 1 via a line 5a and removed via a line 3.

Patent GB-1024144-A (GB)
Title: Process for the preparation of synthetic bitumens
IPC: C10C3/00
Filed: 1965-02-22
Abstract: Synthetic bitumens are made from a straight-run asphaltic residue (or mixtures thereof) and a cracked asphaltic residue (or mixtures thereof) by the following process: each residue (or mixture) is separated into an asphaltene-containing fraction and an oil fraction substantially free of asphaltenes, and at least part of the oil fraction from one residue (or mixture) is mixed with at least part of the asphaltene fraction from the other residue (or mixture).  The cracked and straight-run residues may have the same or different origins, and the synthetic bitumen produced by the above process may be modified by adding to it some of one or both of the two fractions not employed to form the bitumen in question, i.e. some cracked asphaltene fraction and/or some straight-run oil fraction may be added to the bitumen which comprises a cracked oil fraction and a straight-run asphaltene fraction, and vice versa.  The separation of the residues into two fractions may be carried out using a precipitant, e.g. pentane or hexane, and one or more multicyclones, e.g. as described in Specification 935,725.  Two examples are described, using a straight-run distillate from a Middle East crude as starting material, and a flow diagram of the complete process is provided.

Patent GB-1104566-A (GB)
Title: Expanding and moulding thermoplastic material
IPC: C08J9/12
Filed: 1966-02-22
Abstract: Expanded thermoplastic resins are produced by establishing a system having at least one phase containing a thermoplastic resin and a foaming agent composition represented by the formula (M2O)l(SiO2)m(H2O)n, where M is an alkali metal and l:m:n=20:10-100:4-40 by weight, and heating the system to accomplish foaming.  Foaming takes place by heating of the water present in the alkali metal silicate, which is retained in the silicate which hence expands.  The silicate may be removed by water after foaming to leave an open-celled foam, or may be previously rendered insoluble by a compound of aluminium or an alkaline earth metal.  By varying the ratio of l:m:n above, foaming agents foaming at different temperatures may be obtained, and thus may be used a high thermoplasticizing temperature, e.g. polytetrafluoroethylene and polycarbonates. Other specified resins are polypropylene, polyethylene, polyvinyl chloride, polymethacrylates, ABS-copolymers, polyamides and saturated polyesters.  An agent preventing heat deterioration, e.g. a persulphate, peroxide or fluoride may be added to the resin.  The system established may contain in addition to the mixture phase a phase of thermoplastic resin alone, producing a laminate structure, or a phase of foaming agent alone, which when washed out will leave a hollow foamed article. Separate phases of thermoplastic resin and foaming agent composition may be established to form hollow moulded non-porous articles (see Division B5).

Title: Telescope cluster
IPC: F41G7/30
Filed: 1972-02-22
Abstract: 1470753 Mirror scanning system HUGHES AIRCRAFT CO 22 Feb 1972 [1 March 1971]  8202/72 Heading G2J [Also in Division H4] A telescope cluster has three objective lenses, one forming part of a wide field of view visual or acquisition telescope, a second used for wide and intermediate field of view infrared sensing, and a third used in common for a narrow field of view visual system, a narrow field of view infrared system, and received laser beam sensing. The third objective lens 30 channels radiation into a folded optical system, the radiation first being deflected through 90 degrees by a stationary mirror 34 and then striking a spinning composite structure 50, cf. Specification 1470754, transparent to visual radiation but reflecting infrared radiation. The transmitted visual radiation is then reflected by an adjustable mirror 54, cf. Specification 1470755, and passes through a compound prism 58, cf. Specification 1470756, and visual target reticle 104 via a switching mirror 100 and an eye-piece 16 to the observer 10. The switching mirror 100 relays light from either the wide field of view visual telescope 118 or the narrow field of view telescope (as shown in Fig. 6) into the eye-piece 16. The infrared radiation reflected from the spinning composite structure 50 re-strikes the stationary mirror 34 (as shown in Fig. 7) and is reflected on to an infrared detector 46 which is offset from the optical axis of the objective lens 30. The detector 46 may be a conventional L-type orthogonal detector and an inclined dichroic mirror (51) Fig. 3a, (not shown) within the structure 50 produces an optical scan on a pair of orthogonal sensors. The signals from the sensor 46 are fed to an error computer 150, which produces signals representing the deviation of a departing missile from a prescribed course and feeds these signals to the missile controls 152, which then transmit them to the missile steering it toward the target. Immediately upon firing the missile, the infrared radiation from the hot nozzle of the missile was acquired by the second objective lens 48, the radiation being reflected back by a spinning margin mirror 124 to a pair of crossed sensors 126, the signals from which were also fed to the error computer 150. The computer 150 was switched to the sensor 46 when the departing missile closely approached the line of sight to the target. When the target is illuminated from the ground by a laser, a portion of the laser radiation reflected from the target passes through the objective lens 30, is reflected from the folding mirror 34, passes through the composite structure 50 and is reflected by the adjustable mirror 54 on to the end-face of the prism 58. Dichroic mirrors (106, 108) within the prism 58 Fig. 8, (not shown) reflect the radiation into a laser sensor (110), signals from which are delivered to laser sensing circuitry (154), which then determines the angle or range of the incoming laser radiation.
