Patent GB-459634-A (GB)
IPC: G03C7/14
Abstract: 459,634. Colour photography. OPTICOLOR AKT.-GES., Glarus, Switzerland. April 22. 1936, No. 11520. Convention date, April 26, 1935. [Class 98 (ii)] A multiple zone colour filter for use with lenticular element films free from halation comprises individual zones, each of which is composed additively of a coloured portion, and a less coloured or even uncoloured portion. The zones may comprise coloured portions 1, 2, 3 with slightly coloured or transparent portions 4, 5, 6, in the middle of each coloured portion. If it is desired to obtain more saturated reproduction of one colour, e.g. green, the strips 4, 5 and 6 are each coloured minus green. The filter may comprise a metal holder containing the coloured gelatine foils with their transparent portions covered with screening foil containing aesculin to prevent ultra violet light passing through. The transparent portions may be of various shapes, and may also be formed in the opaque masks separating the coloured zones. The portions which are slightly coloured must have like spectrum transparency curves and they increase the general transparency and compensate for the loss of transparency caused by the halationfree film.

Abstract: 1,026,497. Winding coils. GENERAL ELECTRIC CO. Dec. 5, 1962 [Dec. 18, 1961], No. 45983/62. Headings B3A and B3E. [Also in Division H1] A method of making a coil comprises the steps of forming a cavity of substantially the size and shape of the desired coil, randomly laying within said cavity turns of wire and compacting said turns to form a compact randomly wound coil. The cavity is formed by a winding member 24 and a winding cam 26 into which turns are laid by a machine 32. When sufficient turns have been placed in the cavity, the turns 44 are compacted by the ram 46 of a press 45, Fig. 3 (not shown). The member 24 and the cam 26 are removed and the compacted coil, in the mould 20 is placed in an encapsulating machine. The chamber of the machine is evacuated, encapsulating material introduced and heat applied to cure it. Alternatively, the coil may be taped or provided with a supporting form.

Title: Process for recovery of cyclohexanone
IPC: C07C45/84
Filed: 1972-10-11
Abstract: 1353437 Recovery of cyclohexanone STAMICARBON NV 11 Oct 1972 [14 Oct 1971] 46946/72 Heading C2C Cyclohexanone is recovered from the conversion product obtained in the dehydrogenation of cyclohexanol and containing cyclohexanone, oyclohexanol and impurities including water, by azeotropically distilling the product with cyclohexane to remove the water, distilling the remaining product to distil off components having a boiling point lower than that of cyclohexanone and thereafter separating by distillation the cyclohexanone from the remaining fraction containing higher boiling components. The cyclohexanol may be that obtained as a by-product in the production of cyclohexanone by the oxidation of cyclohexane, and the cyclohexane oxidation product freed of acids, esters and non- converted cyclohexane, together with the conversion product obtained in the dehydrogenation of cyclohexanol, may be combined and subjected to the above treatment for removal of water. As shown in Fig. 1, these processes may be combined to form one continuous process. The oxidation product of cyclohexane from which acids, esters and non-converted cyclohexane have been removed is fed through line 1 to preliminary distillation column 2 where light impurities are removed, and thence to distillation column 5 where pure cyclohexanone is recovered through line 6. The remaining product flows to column 8 where cyclohexanol is distilled off overhead and is passed to dehydrogenation unit 11. The dehydrogenation product passes via condenser 13, where hydrogen is removed, to a drying zone 16 where water is removed by azeotropic distillation with cyclohexane. The dried product then flows through line 17 into line 1.

Title: Process for the treatment of material by dry crushing grinding or milling
Inventor: KRIJGER W
IPC: G05D7/06
Filed: 1971-10-11
Abstract: 1361418 Controlling mills KONINKLIJKE NEDERLANDSCHE HOOGOVENS EN STAALFABRIEKEN NV 11 Oct 1971 [12 Oct 1970] 47295/71 Heading B2A [Also in Division G3]  The charge in a dry crushing, grinding or milling plant is maintained constant by an electrical control system. Material is passed into and out of the plant in continuous supply and discharge flows, one supply flow being controlled by a signal dependent on 1 the difference between measured values of supply and discharge flows and 2 the value of sound volume produced by the plant. Thus the supply flow is controlled so that supply and discharge flows are balanced but is modified when necessary to restore the degree of filling of the plant to a desired level. The raw material feed to the mill is measured by a weighbelt 36 and a first signal derived. This is delayed by a time t, corresponding to the time the material takes to pass from the weighbelt to the mill inlet. A second signal is derived from a system 10 which measures the mass per unit time of coarse material flowing at 9, from a cyclone 8, which is recycled back to the input of the mill and thus forms part of the total input. The first and second signals are added and the sum is delayed by a period t 2  corresponding to the time the material takes to pass through the mill 1. This combined delayed signal represents the mass of the delivered flow at the moment of discharge. This is compared with the actual discharge flow 5 by measuring the power used by a driving motor 14 of an elevator 4 and deriving therefrom a third signal which is compared with the combined delayed signal in a device C 1  whose output signal is used to control the motor 13 driving a belt feeder 3. A microphone 15 which responds to noise in the mill, is used to derive a signal which controls a device C 2  which in turn controls the adjustment of the device C 1  by determining its zero point and thus the charge in the mill. The mill system also monitors at 24 and 27 gas pressure upstream and downstream of the mill. The monitored gas pressure at 24 is used to control a cooling air valve 21, and the gas pressure at 27 similarly controls a motor 35 for a valve 34 in the outlet stack. The outlet gas temperature is monitored at 32 and used to control a fuel-supply-valve motor 19 for a drying gas heater 16. In operation of the plant material from a hopper 2 is fed to the mill 1 with hot gas from the heater 16, ground material being fed by the elevator 4 to a second elevator 6 and a cyclone 8. The fines at 11 constitute the product. The coarse faction is recycled at 9. The hot gas is separated at 28 from the coarse fractions which are returned at 26 to the elevator 4. The separated gas is further filtered in an electro-precipitator 29 and the dust is added to the product. The filtered gas is withdrawn by a fan 33 and discharged up the stack.

Abstract: 1,169,557. Universal joints. E. H. SHARP. 24 Oct., 1966 [23 Oct., 1965], No. 47552/66. Heading F2U. In a universal joint having torque transmitting rollers in registering grooves in driving and driven joint members, the rollers are individually retained close to the bisector plane to give substantially constant velocity. As shown in Fig. 2 each torque transmitting roller 23 is integral with a pilot projection 28 slidable in a radial socket 29 in the base of a groove 26 of the inner joint member 21. The surface 30 of the pilot projection 28 is a surface of revolution and so shaped that it remains in contact with the side of socket 29 throughout the angular movement of the inner member relative to the outer member 20. The base of each groove in the outer member may taper outwardly from a central longitudinal plane and the roller 23 have a flat base so that there is permissible pivotal movement of the rollers relative to the outer member 20 in a radial plane. Alternatively the base of the grooves in the outer member may be cylindrical and spacing or antifriction means be provided between the base and the roller to again provide pivotal movement. In the embodiment shown in Fig. 10 a separate pilot member comprises a stem 45 extending through a bore 43 in a torque transmitting roller and formed integrally with an insert 46 co-operating with the cylindrical base of a roller groove in the outer member to provide pivotal movement of the roller. As a further modification the pilot means may have a pair of arms external to the roller and extending outwardly for engagement with a suitable surface of the outer member, and a stem extending inwardly to engage the socket in the inner member. In this case the roller may be a ball.
