Abstract: 1,232,993. Colour television display apparatus. E.M.I. Ltd. 28 June, 1968 [29 July, 1967], No. 34977/67. Heading H4F. Display apparatus for colour television comprises a high definition display means 4 for establishing the brightness aspects of a display, and three lower definition display means 1, 2, 3 for establishing the colour aspects of the display, wherein the control on the lower definition display tends to affect the brightness of the display in a predetermined manner and the high definition display is controlled in such a way as to substantially neutralize this tendency. The three low definition displays 1, 2, 3 are eidophors scanned so as to produce displays representing the red, green and blue components of the scene, these being brought together by mirrors and passed through a fourth eidophor 4 controlled by the luminance signal, the resultant light beam forming the final colour picture display on a screen 5. Alternatively, Fig. 3 (not shown), four eidophors having sources of red, green, blue and white light respectively are each scanned and the four displays are brought together by a mirror system, the red, green and blue eidophors being controlled by colour component signals to form a low definition picture and the white eidophor being controlled by the luminance signal from which the brightness component already supplied by the other tubes has been removed. It is arranged that the A.C. control signal of the fourth eidophor contains no negative excursions.

In the heat pretreatment of liquids, particularly milk, the liquid is passed to a condenser where it is heated by contact with vapour which has been recirculated from a flash vessel, the treated liquid is then pumped to a steam injector for further heating, and then passed through a restriction to flash vessel which is maintained at a lower pressure whereby vapour is flashed off to the condensing vessel, the cooled liquid being pumped away for further treatment. A suitable apparatus may comprise a condenser in communication with a flash vessel, a steam injector, pump and restriction (Fig. 1, not shown). Alternatively the condensing vessel may be located in the flash vessel. This alternative is shown in Fig. 2 wherein liquid from a heat exchanger is sprayed into an inner chamber 15 which is filled with vapour. The heated liquid is extracted by means of a pump 8, passed through a steam injector and restriction and into the flash chamber 16 via inlet 16a. Vapour generated in this vessel passes through a number of holes 17 into the inner vessel for contact with feed liquid. Cooled feed liquid is removed from the outer vessel by pumping and may then be subjected to evaporation.

Abstract: 1289285 Light deflection apparatus INTERNATIONAL BUSINESS MACHINES CORP 12 March 1970 [7 April 1969] 12040/70 Heading G2J [Also in Division B6] Light deflection apparatus in which astigmatic aberrations caused by the propagation of extraordinary rays through birefringent elements is avoided comprises a transparent medium (e.g. an oil bath) of refractive index Á enclosing two negative birefringent plates 20, 21 of ordinary refractive index Á (e.g. calcite) and two adjustable isotropic plates 22, 23 of refractive index less than Á (e.g. sodium fluoride) arranged as in Fig.3, and polarizing means (not shown) located on the side of plate 20 remote from plate 22 to direct on to plate 20 light polarized either in the ordinary or in the extraordinary sense at an angle of incidence greater than the critical angle for the extraordinary refractive index. The optic axes 24, 25 of plates 20, 21 are disposed in perpendicular planes and the polarizing means (e.g. a KDP crystal) presents a light beam 26 having a linear polarization in one of two orthogonal states. When beam 26 has a polarization in a plane corresponding to the plane of axis 24, it encounters the lower (extraordinary) refractive index of plate 20 and is thus reflected as beam 27; this encounters the higher (ordinary) refractive index p of plate 21 and passes through without refraction to be reflected at the incident face of plate 23 as beam 28. If the polarization of beam 26 is in a perpendicular plane it encounters first the higher index Á of plate 20 and then the lower index of plate 21. To ensure that both possible output beams have the same pathlength, an optical element 34 of refractive index greater than Á is inserted in the path of beam 31, and each output beam is controlled only by altering the difference between distances h 1  and h 2  (which may be adjusted so that plate 23 can be formed as a coating on plate 21). Any number of such arrangements may be assembled, n such arrangements in any one plane yielding 2<SP>n</SP> possible output beams Fig. 4 (not shown). Alternative arrangements are illustrated in Figs. 5 and 7 (not shown). A number of the above arrangements 85-88 (Fig.8) may be assembled together with a laser input 80 and a number of telescoping lenses 90-95 in order to select a character from a matrix 82 and to position it at a desired location on an output medium 84.

Abstract: 1318188 Paste-delivering apparatus MOLINS MACHINE CO Ltd 4 Aug 1970 [4 Aug 1969] 38892/69 Heading F1R Apparatus for delivering an uninterrupted supply of paste comprises main and auxiliary containers 8 and 56 from which paste can be discharged by the action of rams 16 and 60 to a delivery passage 14, the arrangement being such that ram 60 is actuated when container 8 is empty and resumption of operation by ram 16 results initially in some paste going to passage 14 and some to the auxiliary container to fill it, a pipe 68 being connected to atmosphere via a relief valve which produces a back pressure controlling the return movement of ram 60. Actuation of a switch 28 by ram 16 as it empties the container 8 effects both connection of a solenoid-operated valve 38 with an input 44 for rapid return of the ram and actuation of ram 60. Container 56 may be replaced by an in-line container 74, Fig.2, paste then passing through hollow bores in pistons 76, 78 and out through pipe 14. Actuation of switch 28 causes air to be pumped into space 90, forcing piston 78 to expel the paste in chamber 72; when container 8 resumes operation, paste is pumped through the bores to pipe 14, thereby raising pistons 76, 78 and re-filling chamber 72 while a relief valve 91 again controls upward movement of the pistons.
