Abstract: 722,635. Self-sealing electric condensers. BOSCH GES., R. Oct. 1, 1952 (Oct. 3, 1951], No. 24530/52. Class 37. The metal coating on the dielectric strip of a self-sealing condenser has a conductivity not greater than that of zinc, a thickness between 0.01 and 0.05 Á, and is applied by condensation about condensation nuclei of suitable material (e.g. silver in the case of a zinc coating) previously deposited thereon with a monatomic distribution ratio, as defined in the Specification, of approximately 10<SP>-2</SP>. The coating and undercoating being, in effect, " dispersed " over the dielectric, present at least twice the layer resistance that would obtain were the coatings compact structures. Zinc and cadmium may be used for the final coating material, the desired structure being achieved for example by condensation from the gas phase of the metal in question at high vapour density or by electrolytic deposition. Specification 722,636 is referred to.

Title: Dispersion refractometer apparatus
IPC: G01S11/12
Filed: 1978-07-19
Abstract: Light from a light source 12 is polarisation or phase modulated in a modulator 15 of a transmitting unit 10. The modulated light is transmitted over a path D the integrated refractivity correction of which is to be determined to a receiving unit 11 in which, in a preferred embodiment, it is split into a blue light beam and a yellow light beam. A modulator 32 determines the modulation phase of the blue light beam relative to yellow light beam. A variable light path device 26 is adjusted to vary the length of the path, and so the modulation phase, of the yellow light beam relative to the blue light beam until the modulator 32 detects a predetermined modulation phase. The adjustment made to the variable light path device 26 thus provides an indication of the integrated refractivity correction. <IMAGE>

Patent GB-2021863-A (GB)
Title: Method of making integrated circuits
IPC: H01L21/285
Filed: 1979-05-24
Abstract: Field oxide 50 is grown on a silicon substrate to separate FET and diffused line conductor areas on which are grown thermal silicon dioxide and silicon nitride which may have an oxynitride surface resulting from the thermal field oxide growing. A polysilicon layer 60 is applied, oxidized to form a silicon dioxide layer 62 and then another nitride layer is applied, masked and etched to leave a protective gate contact button 200. Exposed polysilicon is further oxidised. FET and contact areas are masked and unmasked oxynitride and nitride are removed. Another oxidation step oxidises the surface of the diffused line conductor. Batch treatment (unmasked) is used to remove the oxynitride/nitride buttons 200 and areas of layer 36 over the source and drain S and D and over the contact area to the diffused line N+. A conductor pattern can then be applied to contact the gate polysilicon, the source, drain and diffused line, either without or with application of a further silicon dioxide (Silox) layer etched to re-open the apertures formed by the oxynitride/nitride removal. <IMAGE>

Title: Cigarette weight monitoring system
IPC: G01G9/00
Filed: 1979-10-02
Abstract: Cigarette-rod weight monitoring system in which the signals from a scanner, e.g. a nucleonic device such as Molins "MODIC", (42) are processed and stored in a memory (48) in a digitised form, and the memory contents are used to drive an analogue display device (54). These signals, which represent the individual cigarettes, or short lengths, are accumulated in the memory over a period which is sufficiently long for a statistically significant distribution pattern to be achieved, so that the shape of the distribution curve can be observed to determine whether it is "normal" or whether any skews or other irregularities are present. In addition the accumulated signals can be analysed in various ways to provide quantitative measurements of overall standard deviation, or effective standard deviation either side of the mean to show whether any "skews" exist. S.D. can be calculated for whole cigarettes or short lengths for different diagnostic purposes. <IMAGE>

Title: Continuous cladding of an elongate element
IPC: B29C44/24
Filed: 1980-12-10
Abstract: In a method of continuous cladding of an element of indefinite length with a cladding material, a flat strop 4 of flexible material is moved into a cylindrical passage defined between opposed movable shaping elements 2, 3, so as to form a hollow cylindrical sheath of the flexible material. The elongated element to be clad is moved centrally and longitudinally in the sheath so as to define a space between the element and the sheath. The cladding material is then introduced at 5 into that space, upstream of the movable shaping elements, and is allowed to set. Preferably the opposed movable shaping elements and the flat strip material each move in respective closed loop paths, and advantageously all at the same speed. <IMAGE>
Patent GB-2069286-A (GB)
Title: Photographic camera of automatic focussing type
IPC: G03B13/36
Filed: 1980-12-29
Abstract: A photographic camera of the automatic focussing type has light sensors (9, 10) which provide signals having an extreme value at the in-focus position. In a range near the in-focus position an electrical circuit (Figure 5) can detect the correct direction to move the objective towards the in-focus position. Outside this range the objective is moved in one direction, and if it reaches the limit of its travel without passing the in-focus position (i.e. it was driven the wrong way) one of two switches (24, 25) is actuated to reverse its direction. When outside the said range the objective is moved more quickly than when within it. Steps can be taken, especially if a self-scanning image sensor is used as light sensor, to compensate for changes in brightness avoiding changes in speed of movement of the objective on this account. <IMAGE>
