Patent GB-760699-A (GB)
Title: Preparation of novolak resins
Inventor: FRASER DONALD ALEXANDER
IPC: C08G8/08
Filed: 1953-09-26
Abstract: In making a novolak resin by condensing a molar excess of phenolic compounds containing phenol, meta-cresol or meta-ethyl phenol with formaldehyde, the reaction is effected at a pH of 4 to 7 in the presence of the oxide or hydroxide of divalent cadmium as condensation catalyst.  Other phenols may be used in conjunction with at least one of the aforementioned phenols, e.g. commercial xylenols. The preferred starting material is pure phenol or an isomeric mixture of cresols containing m-cresol.  The molar ratio of phenols to formaldehyde is preferably from 1.8:1 to 2.5:1.  The reaction is effected by mixing the phenol(s) and formaldehyde (as formalin or paraformaldehyde), adding the catalyst thereto and heating gently until reaction occurs, volatile compounds being allowed to distif off until the temperature reaches 150 DEG  to 160 DEG C. When the desired degree of condensation has been reached, residual volatile compounds, e.g. unreacted phenols, may then be removed either by vacuum distillation or by addition of further formaldehyde with further heating.  Examples are given.

Filed: 1975-06-24
Abstract: 1470947 Blow moulding multilayer containers DAIWA CAN CO Ltd 24 June 1975 [29 June 1974] 26709/75 Heading B5A To improve the surface finish of an extrusion blow-moulded container, the container is blown from a parison having a main layer at a temperature suitable for blow moulding and an outer layer at a temperature above that at which it could be satisfactorily blow moulded on its own but below that at which it would be substantially drawn down on the main layer during blowing. Parisons of two or more layers of polyethylene, polypropylene or nylon, with a relatively thin outer layer hotter than the main layers, produce higher lustre, lower surface roughness, and greater transparency than similar parisons with all the layers at the same temperature.

Title: Data recording system
IPC: G06F3/02
Filed: 1963-07-09
Abstract: 1,046,789. Data storage; feeding record tapes. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 9, 1963 [July 9, 1962], No. 27052/63. Headings G4C and G5R. In a system for recording data magnetically on a record member moving relative to a recording means, the recording means scans the record member for a reference mark indicating the last data character to be recorded and records the next character and a further reference mark at a fixed position relative to first reference mark. This ensures that the characters are evenly spaced without the use of a space incrementing device or a clock timing system. As described, a magnetic tape 14 from a supply spool 13 to a take-up spool 17 passes round a guide plate 15 mounted on a constantly rotating disc 11. The tape is arranged for periodic advance relative to the disc in a direction (indicated by the arrows) opposite to that of the disc but at a speed much lower than that of the disc, and is effectively stationary relative to it. The advances are made when the portion of tape adjacent the sector 15 is two-thirds full causing a pulse from the read-write head 12 to coincide with a pulse from a photo-cell 70 in a control circuit 34 which start a tape feed motor 22. For recording data on the tape, the disc 11 rotates and the head 12 scans the portion of the tape adjacent the sector 15 in reverse order, i.e. it scans any characters recorded on it in an order opposite to that in which they were recorded. Initially when there are no characters already recorded the scan continues until the head 12 detects a starting reference mark 30 (Fig. 4, not shown) in the reference track; then recording heads arranged one character behind the reading head in the head 12, write the bits of a character 29 in the data tracks and a further reference mark 31 in the data track. During the next revolution of the disc 11, the mark 31 is read before the mark 30 and the next character 33 and its corresponding reference mark are similarly recorded the same distance behind the character 29. For reading, the reference marks 31 are erased, leaving the permanent reference 30, and the scanning starts again as for recording; the reference track is scanned and, when the mark 30 is detected, the word 21 is read and the mark 31 is re-written so that it is detected during the next scan and the words 33 &c. are read.

Title: Improvements relating to electric capacitors and printed circuits containing capacitors
IPC: H05K3/06
Filed: 1948-10-20
Abstract: 690,328. Making electric condensers etc.; foil. STRONG, H. V., and EISLER, P. Nov. 18, 1949 [Oct. 20, 1948; Nov. 11, 1948], Nos. 27195/48 and 29350/48. Class 83 (ii). [Also in Group XXXVI] A method of making a multi-layer capacitor or printed circuit sheet material comprises applying a layer of an etch-resistant dielectric material to one surface of a conductive metal foil, protecting the opposite surface of the foil with an etch-resistant material, subjecting the prepared foil to an etching treatment to etch away metal from areas of the foil exposed by interruptions in the etch-resistant coatings and from areas in the immediate proximity thereof, and thereafter superimposing a layer of conductive material over the dielectric layer. The foil may be of aluminium, though copper or tinned copper are preferred. The aluminium may be anodized but the oxide layer must be of a limited thickness to allow a core of metallic aluminium to remain. An oxidizing ink comprising sodium or potassium chromate, anhydrous sodium carbonate, caustic acid, glycerine and water may be applied by roller in a very thin film and after several minutes washed off, e.g. in a boiling weak solution of potassium dichromate. Fig. 4 shows a cavity 15 eaten away by the etch solution which has passed through the pinhole 14 in the etch-resisting insulating material 11, 12. A second coating, e.g. of wax made flexible by combination with rubber resin or enamel may be applied after which, e.g. for a capacitor in a printed circuit a second foil may be superposed and bonded on the dielectric coating. Insulating cement, conductive cement or bonding by heated rollers may be used. Instead of the second foil a conductive coating may be applied as in Figs. 5 and 6 (not shown), where polythene is the dielectric and an envelope surrounding the layers is of polystyrene. To permit various lengths or areas of multilayer insulated sheet foil to be cut off without causing burrs of one foil to contact with the next foil, parallel strips or cross-shaped areas are left bare in the single insulated foil sheets and after etching treatment, the sheets are superposed so that no burr on one foil is immediately above another bare foil portion. Where space for capacitors, e.g. in printed circuits is limited, they may be folded on a stiff piece of insulation and mounted vertically or rolled or otherwise folded. The permittivity of the dielectric coatings may be increased by embedding therein particles of high permittivity (as described in Specification 690,360, [Group XXXVI]). Specifications 441,088, [Group II], 639,111, 639,658, and 685,912, [all in Group XXXVI], are referred to.
