Title: Improvements in or relating to the deposition of adherent layers of powdered material on surfaces by a settling process
IPC: H01J9/22
Filed: 1950-11-21
Abstract: A method of forming on a surface, such as the glass end plate of a C.R.T. envelope, an adherent layer of one or more powders p  which may be luminescent and which are insoluble or only slightly soluble in water, includes the steps of settling the powdered material on to the surface from suspension in an aqueous solution of a silicate, after completion of the settling heating the settled powder layer and the supernatant liquid to a temperature within the range of 50 DEG to 90 DEG  C. for not more than 1 hour, and removing the supernatant liquid when the settled powder layer has become sufficiently adherent.  The suspension may contain 10 grs. to 100 grs. of powder per litre, preferably 30 to 40 grs. per litre.  The particles of the powder may range from 5 m  to 30m  in diameter.  The powder may consist of luminescent Ag-activated ZnS and/or Ag-activated ZnCdS. The silicte employed may be a potassium silicate containing from 3 to 4 mols. of SiO2 to 1 mol. of K2O.  The heating may be carried out slowly by irradiation by one or more infra-red lamps.  The aqueous solution of the silicate can include a small proportion of one or more electrolytes, for example Na2SO4 at a concentration of 0.1 mol. per litre of the silicate solution.  The surface may be covered to a depth of about 2 inches with the settling liquid containing the silicate and a separately prepared concentrated suspension of the powdered material in water or in a silicate solution then distributed over the surface of the settling liquid. Double and triple layer luminescent screens are also referred to. When the luminescent powder is applied to a C.R.T. the envelope is first washed with a 6 per cent solution of hydrofluoric acid, rinsed with hot water, washed with hot 10 per cent caustic soda, rinsed with hot water and finally rinsed with distilled or de-mineralized water at room temperature.  The luminescent screen may be coated with an aluminium backing layer.

Title: Improvements in and relating to methods for applying fibrous coatings to filaments
IPC: H01B13/12
Filed: 1933-10-14
Abstract: 411,731. Covering electric conductors and other cores. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Lewis, E. H. ; 62, Laurel Place, Bridgeport, Connecticut, and Luttenberger, B. W. ; Manheim, Pennsylvania, both in U.S.A.) Oct. 14, 1933, No. 28455. Convention date, Oct. 14, 1932. [Class 109.] Asbestos or other fibres are applied to a conductor or other core to form a felted coating thereon by passing the core 3 through a mass of intermingled non-parallel fibres to which a rotation about the filament is imparted. Upon leaving the doffer 13 of a carding machine, the fibres are acted upon by a comb 14 which destroys the parallelism of the fibres and delivers them in a loosely associated and interengaged condition so that they fall on to the core 3. A liquid adhesive material is applied to the core before it reaches the comb 14. The core, with the fibres loosely disposed thereabout, passes to a whirl 17 which is rotated at high speed. A smoothing or polishing plate 19<a> may be provided, and the covered core may be dried and have talc or other dry powder applied to it. In forming a heater cord, Fig. 9, two conductors 203<r>, 203<v> are surrounded by a coating 203<c> of rubber or other insulating material, the conductors are united by an insulating coating 203d, and finally a felted coating 203b is applied. Alternatively, the felted coating may be applied to each of the conductors around the coating 203<c> before the conductors are united by the band 203d.

Abstract: 1,164,773. Liquefied gas storage containers. LINDE A.G. 17 June, 1968 [16 June, 1967], No. 28701/68. Heading F4P. A heat insulated cold liquefied gas storage container 2, 3, Fig. 1, has thermometers 6 located at at least two different depths within the liquid space and means responsive to a predetermined temperature rise shown by the lower thermometer over the one at a higher level for reducing the temperature of the liquid adjacent the container bottom. The temperature rise near the bottom of the container is due to unavoidable heat penetration through the insulation 4 which causes a fall in density and "layering" of the liquid which rises to the top and rapidly evaporates at the lower hydrostatic pressure at said top. Said means comprises a pump 10 which automatically withdraws the warm bottom liquid through a line 11 and delivers it through a line 12 to the container top. In a modification the reduction of temperature of the bottom liquid is effected by convection up an open-ended tube 8, Fig. 2, surrounded by an outer tube 7 sealed thereto and housing an electric heater 9.

Title: Control system for motor road vehicles
IPC: G05D1/02
Filed: 1959-08-25
Abstract: 896,395. Signalling passage of vehicles. GENERAL MOTORS CORPORATION. Aug. 25, 1959 [Sept. 8, 1958], No. 29022/59. Class 118. [Also in Group XXXVI] A control system for motor road vehicles comprises means for radiating an electromagnetic field above and along a roadway, pairs of stationary mutually-opposed pick-up means disposed along the roadway and means when an object disturbs the coupling between the radiating and the pick-up means for distinguishing between objects of different speeds. As described the invention is employed in conjunction with a leader cable 14 (Fig. 1) fed with alternating current and laid below a roadway 10 in order to ensure that vehicles travelling along the roadway 10 follow a predetermined path. Pick-up coils 20 are arranged as a series of oppositely-connected pairs so that normally no input is applied to an amplifier valve 34. The presence of a vehicle (or other obstacle) causes unbalance in the coils 20 and the resultant output from the amplifier 34 is rectified and applied to a capacitor 50. If a vehicle is stationary or travelling dangerously below its desired speed, the capacitor 50 will charge sufficiently to cause an output valve 58 to conduct, thus operating its anode relay 62 and lighting an indicator lamp 66. Instead of lighting a lamp, the relay 62 may control means to automatically increase the speed of the vehicle, such as that disclosed and claimed in Specification 896,394. In a more comprehensive embodiment (Fig. 2) the coils 72 are arranged in two groups 68, 70 each group consisting of a balanced arrangement normally producing no output current. The presence of a vehicle cannot affect an even number of coils in each group, and so produces an input to either or both of two amplifiers 82, 94 and thus a rectified voltage on either or both of two series capacitors 88, 100 to cause the output valve 104 to conduct, operating the anode relay 109 and lighting the indicator lamp 112. A ripple voltage due to the passage of a vehicle is taken from the input to rectifier 98 and applied via an amplifier. 118 and rectifier 121 to a further capacitor 122. If the vehicle is travelling at the desired speed; the charge on capacitor 122 balances that on capacitors 88, 100 and no indication is given on the lamp 112. The voltage on capacitor 122 mayalso be applied to a triode 126, and a vehicle travelling faster than the desired speed will produce a sufficiently heavy charge on the capacitor 122 to bias the triode 126 below cut-off and thus release its anode relay 130 to light a further indicator lamp 133.

Abstract: 742,440. Crimping fibres. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Sept. 29, 1954 [Oct. 21, 1953], No. 29029/53. Class 120 (3). Apparatus for crimping artificial filaments between gear wheels comprises a device. which automatically effects disengagement of. the wheels when excessive pressure develops therebetween. In one form, the device comprises a pair of weak retaining bolts each of which holds movably mounted bearings on either side of at least one of the wheel shafts: excess pressure causes shearing of the bolts and one wheel is detached from the other by a pair of springs. In the apparatus shown, a driven, steam-heated gear wheel 1 is mounted on fixed shaft bearings 2 and 3 and normally engages an idler gear wheel 4 mounted on slidable shaft bearings 5 and 6; when excessive pressure between the wheels occurs, a shear pin 15 fails in a double shearing action between a link 13 and a fixed support 17, thereby releasing a spring 14 which pulls the wheel 4 out of mesh with the wheel 1 by means of a system of levers 7, 8, 9, 10 and 13. The shear pin may be replaced by a spring-loaded catch e.g. a tapering or rounded bolt resting in a recess or notch in a bar, which is released by the excess pressure. The device may be combined with stop-mechanism for arresting the drive to the gear wheels and/or the feeding of tow to the apparatus.
