Abstract: 1,260,077. Colour television tubes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 3 Sept., 1970 [6 Sept., 1969], No. 42246/70. Heading H1D. In a colour television tube wherein a shadow mask is supported in a faceplate by means of resilient members attached to the mask and provided with apertures which engage studs on the faceplate, the greater thermal expansion and hardness of the members may cause them to deform the studs when they shrink on cooling from the high temperatures employed in processing the tube; the rigidity caused by this effect is avoided by making the apertures in the resilient members circular and the studs triangular with rounded apices. The resilient members may be bimetal strips, the strips being joined along their narrow edges and the aperture being provided in the strip having the larger thermal expansion coefficient. The studs are conical and the angle of the cone should preferably be increased from the usual 15 to 20 degrees. As a modification the studs may be secured to the resilient members and the apertures pro - vided in the envelope or in a member secured to the envelope.

Title: Apparatus for optically reading signals recorded on a record carrier
IPC: G11B7/1353
Filed: 1977-10-12
Abstract: Apparatus for reading optically detectable indicia on a record carrier, such as video information which is recorded in the form of pits on a record medium, for example, a video disc. A source of coherent light transmits a beam to the record carrier. A hologram is interposed between the coherent light source and the carrier, the hologram serving to focus the beam on the record carrier. The intensity of the focussed beam is modulated by the recorded indicia, and at least one photodetector is disposed in an optical path traversed by the modulated beam so as to detect the intensity thereof. In a preferred embodiment, the hologram focusses the beam onto the surface of the record medium whereat it is modulated and reflected therefrom to the photodetector. Plural photodetectors may be provided in separate optical paths traversed by the reflected light so as to produce outputs which, upon comparison with each other, represent deviations, or tracking errors, in the location of incidence of the light beam on the record medium. In yet another embodiment, the hologram directs the coherent light to the record medium along two different optical paths so that the reflection of one beam can be used to read out the recorded information and the reflection of the other beam can be used to detect focussing fluctuations. In a still further embodiment, another hologram is used to receive and direct reflected light to the photodetector.

Whilst the brake shoes are disengaged from the disc 3, drive to the disc is imparted by a follower 21 having a roller 22 engaging in a recess 23 in the disc 3. The carrier disc 1 is secured to a vehicle wheel rim 26 by means of a clamping device having an annular recess in which is housed a tube 29 the interior cavity 30 of which may be pressurized by liquid or gas to cause it to grip the wheel rim 26. The Specification describes a process by which vehicle wheels with the above described device attached thereto are run up to speed to force the respective aligning discs 3 by use of driven rollers and then brought to rest so clamping the discs 3 in position with their flat outer surfaces parallel to the plane of rotation of the respective wheel. These surfaces are then used in determing the geometry of the vehicle wheels.

[Also in Division G2] Droplets of hydrophilic liquid are encapsulated by preparing a first and a second liquid phase comprising, respectively, a hydrophobic liquid or a solution or dispersion in such a liquid and an hydrophilic liquid or a solution or dispersion in such a liquid, the two liquid phases being substantially immiscible and each comprising a substance which is capable of reacting with a substance in the other phase to form a polymer which is insoluble in both phases, and dispensing the said second liquid phase as droplets in the said first liquid phase to cause a reaction at the interfaces between the phases whereby the hydrophilic liquid droplets are enveloped in a polymer coating. Numerous reactive " couples " are disclosed which react to form condensation type polymers e.g. hydrophobic low molecular compounds or prepolymers having two or more functional groups such as -CNS, -CNO, -CO-Hal, -NH 2 , -SO 2 Cl, epoxy, halogen and chloroformate groups (in the hydrophobic phase) and a hydrophilic compound or prepolymer containing two or more functional groups such as -OH, -NH, -NH 2 , -SH, epoxy or methylol groups (in the hydrophilic phase). In this case the reactants from both phases react to form a polymer at the interfaces. Alternatively, one phase may contain a prepolymer or precondensate and the second phase may contain a polymerization catalyst (either the catalyst or prepolymer being hydrophobic) or the hydrophobic phase may contain a low molecular compound having two or more different functional groups, one being an amino or imino group and the other being an acid chloride or chloroformate group which undergoes selfcondensation in the presence of a hydrogen ion acceptor (e.g. an alkali) which is contained in the hydrophilic phase.

Title: Improvements in or relating to graphite
IPC: B01J19/02
Filed: 1959-12-18
Abstract: The permeability of a carbon or graphite body is reduced by impregnating the body with a mixture of a thermosetting monomer and a polymerization catalyst effective at elevated temperature, rapidly polymerizing the monomer at the surface of the body by the application of a polymerization catalyst effective at ordinary temperature, and heating the body so as to polymerize the bulk of the monomer.  Monomers specified are phenol-formaldehyde, urea-formaldehyde, and furfuryl alcohol.  Catalysts specified for the polymerization of furfuryl alcohol at elevated temperature are benzal and benzyl chloride, cyclohexene dibromide, and trichlorobenzene.  A concentrated aqueous solution of hydrogen chloride may be used as the catalyst effective at ordinary temperature.  The polymer may be carbonized within the body.  The permeability of the body may be further decreased by depositing carbon within remaining pores of the body from a hydrocarbon gas. According to the example, a graphite tube closed at one end is impregnated under vacuum with furfuryl alcohol containing 1% of benzal chloride, immersed in rapidly agitated hydrochloric acid solution for 15 minutes, heated at 120 DEG C. for 48 hours, and finally heated at a rate of temperature increase of 5 DEG C. per hour, to a temperature of 800 DEG C. in an atmosphere of nitrogen.  The permeability coefficient is thereby decreased from 2,8 X 10-2 to 1,4 X 10-6 cm2/sec.
