Title: Pressure Sensitive Adhesive Films
IPC: C09J7/22
Filed: 1968-07-12
Abstract: 1,187,716. Pressure sensitive adhesive films. SEKISUI KAGAKU KOGYO K.K. 12 July, 1968 [12 July, 1967; 16 Sept., 1967], No. 33457/ 68. Heading B2E. [Also in Division C3] A pressure-sensitive adhesive film comprises a flexible synthetic resin film having a vinyl or a diene monomer graft-polymerised onto one face, and coated onto the face a layer of a pressure sensitive adhesive containing a natural or synthetic rubber or a synthetic resin. The graft-polymerised vinyl monomer may be styrene, vinyl acetate, vinyl chloride, acrylates and methacrylates e.g. methyl methacrylate, methacrylic acid, acrylonitrile or acrylamide; and the graft-polymerised diene monomer may be butadiene, chloroprene or isoprene. The synthetic resin film may be of polyethylene, copolymers of ethylene and 5- 50% by wt. vinylacetate, copolymers of ethylene and vinyl chloride, polypropylene, polyethylene terephthalate or fluorine-containing polymers e.g., polytetrafluoro ethylene and polymers of chlorotrifluoroethylene and of vinyl fluoride. The rubber or synthetic resin of the adhesive layer and the graft-polymerised polymer of the vinyl or diene monomer may have similar solubility parameters. The rubber or synthetic resin component of the adhesive may be a graft polymer of a natural or synthetic rubber or a synthetic resin with a vinyl or diene monomer - which may be the same monomer as is graft-polymerised to the flexible film face. The adhesive may contain a rubber of low polarity and a layer of primer may be between the film face and the adhesive layer. The primer may comprise a mixture of natural or synthetic rubber with another polymer having a similar solubility parameter to the graft polymerised polymer of the vinyl or diene monomer; or a graft polymer of the vinyl or diene monomer grafted to natural or a synthetic rubber which graft polymer may have a solubility parameter similar to that of the graft polymerised polymer of the vinyl or diene monomer grafted to the flexible film. One face of the flexible film is contacted with the vinyl or diene monomer, caused to graft-polymerise to the face of the film e.g. by irradiation with ionising radiation which may have an intensity of 0.1 to 10 megarads, and coated with the adhesive or with primer and then with adhesive. One or more vinyl or diene monomer may be applied as a thin layer to the interior or exterior of a tubular film, irradiated, and the tube then cut into a flap tape. Alternatively, one face of the film is coated with a mixture of the vinyl or diene monomer and a natural or synthetic rubber e.g., a solution of the rubber in the monomer, irradiated or heated with a catalyst so as to cause part of the monomer to graft polymerise to the surface of the film and part of the rubber, and then coated with a layer of adhesive. Examples of adhesives are given. The primer and adhesive coatings may be applied by knife or roll coating methods.

Abstract: 449,470. Valve circuits. RADIOAKT.- GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. Nov. 24, 1934, No. 33806. Convention date, Nov. 24, 1933. [Classes 40 (iii) and 40 (v)] High selectivity is obtained in a receiver particularly intended for the reception of television signals, by the use of a piezo-electric crystal 12 connected in the intermediatefrequency stage of a superheterodyne receiver. The signals are applied to a twin-grid frequencychanger 7 from the common point of two aerial resistances 2, 3. The intermediate frequency passed to the transformer 10, 11 is higher than the received signal frequency and is transferred to a capacity bridge comprising condensers 13, 14, 15 and the crystal 12. To maintain the mid-point of the transformer secondary 11 at earth potential, the primary winding may be split, each half being coupled to one end of the secondary 11 and the mid-point earthed, Fig. 2 (not shown). By means of the bridge only the resonance frequency of the crystal passes without attenuation to a second frequencychanger 18. To widen the response curve, two crystals having a difference of 5000 cycles may be arranged side by side in the mounting 12, or one crystal may be stepped or ground to wedge shape. The cutting-off of the higher modulation frequencies may be compensated by low-frequency correction circuits in known manner. The second frequency changer 18 reduces the frequency, the output being passed through a frequency-correcting band-filter 21, 22 to a normal receiver 24 for detection and reproduction. The entire apparatus concerned with the first intermediate frequency is carefully screened at 16, 17. Specification 443,046 is referred to.

Title: Improvements in or relating to a process and installation for separating and obtaining tar, ammonia and ammoniacal liquor for gaseous products of dry distillation
IPC: C10C1/00
Filed: 1954-11-23
Abstract: 796,095. Purifying gases. STILL, K. F., [trading as STILL, C. [Firm of]]. Nov. 23, 1954 [Nov. 23, 1953], No. 33985/54. Class 55 (2). In a process for separating and obtaining tar, ammonia and ammonia liquor from gaseous products of dry distillation in which the gaseous products pass successively from a knee riser 1 through a first-treatment vessel 2 directly sprinkled at 33, inclined pipes 3, 4, an indirectly cooled gas cooler 5 in which the gas is cooled to the ordinary temperature by cooling water entering at 6 and passing up through tubes to the top 7, and a directly sprinkled evaporator 11, the sprinkling at 16 inside the evaporator 11 is performed exclusively with excess liquid, present in the first-treatment vessel 2 and gas cooler 5 brought in by the hot crude gaseous products, in a manner such that the liquid is withdrawn from circulation between the gas cooler 5 and first-treatment vessel 2 through pipe 21, tar separator 22 and overflow 35 to the suction pipe 36 of conveyer pump 37 and through pipes 38, 39 to the sprinkler 16 and then kept separate, and after passage through the evaporator 11, the liquid is drained through pipe 41, part being removed by waste pipe 42 and part passing through pipe 43 to be reheated in the heat exchanger 29 with hot liquor from the first-treatment vessel 2 and then introduced again through pipes 44, 45 to the suction pipe 36 and thence into the top portion of the evaporator 11 as sprinkling liquid, the amount of sprinkling liquid so circulating through the evaporator being reduced to a degree such that the amount of vapour admixed with the gas leaving the evaporator at 12 is considerably less than the amount of excess liquid brought in by the hot crude gaseous products. After passing through the gas cooler 5, the gas at room temperature is withdrawn by a suction-pipe 8 of a gas extractor 9 and pumped through pipe 10 into the evaporator 11. After leaving the top of the evaporator through pipe 12, it passes through a superheater 13 into a saturator 14 charged with sulphuric acid and passes out through pipe 15. The condensates, tar and ammoniacal liquor formed in the gas cooler 5 are extracted by pipe 17 of pump 18 and passed through pipes 19, 20 back into the first-treatment vessel 2. This liquor and that from the sprinkler 33 pass into the pipe 21 from the inclined pipes 3, 4 and thence into the tar separating installation 22, where the tar separates into the lower chamber 24 and flows out through tube 40. The aqueous ammonia condensate 23 overflows through pipe 35 and also through pipe 26 to a jacket 25 surrounding the tar chamber 24 so as to keep it hot, the liquid then flowing through tube 27 and pipe 28 to the heat exchanger 29 and through pipe 30 where it is pumped by pump 31 and pipe 32 back to the sprinkler 33, the liquid being cooled to about 82‹ C.

Filed: 1973-05-11
Abstract: 1362345 Manufacture of inverted bipolar transistors MULLARD Ltd 11 May 1973 [20 July 1972] 34035/72 Heading H1K In making the base region of an inverted bipolar transistor by ion implantation through a surface masking layer into a layer of one conductivity type on a higher conductivity region of the same type, the portion of the masking layer immediately adjacent the window is constructed to be semi-permeable to the ions to provide a peripheral region of the base in which the ions are less deeply implanted, while the ions in the unmasked region extend to the higher conductivity region. The described processes start with an epitaxial N layer on an N + silicon substrate which ultimately constitutes the emitter zone. Thick oxide is thermally grown over the layer, apertured by photolithographic and etching steps, a thinner oxide regrown in the aperture and similarly apertured at one side, the etching being such that the apertures have chamfered edges. Bombardment with 500 keV boron ions produces a base zone which extends to the surface under the thin oxide to form a contact region and under the chamfered edge, and an unconverted N-type collector region at the exposed silicon surface. The base contact region may alternatively be formed in a separate diffusion or implantation step. After annealing at 700 C. and optionally providing a collector contact region by diffusion or implantation a base contact hole is etched and aluminium deposited and pattern etched to form the base and collector electrodes, and an emitter  contact provided on the back of the wafer. In a modification for integrated circuit use the N+ silicon is a diffused inclusion in a P-type substrate and an emitter electrode provided on the upper face contacts the inclusion via a connecting region. In a further variant the ion energy is such that the base zone extends also to the exposed surface, on which a Schottky collector electrode is provided. The mask aperture may alternatively be provided with a stepped edge either by depositing silica on or diffusing phosphorus into the surface of the grown oxide to provide a faster etching layer to increase undercutting of the photoresist etching mask. A similar effect is obtained by depositing metal over the oxide, using it to mask preferential etching of the oxide and then preferentially etching it to undercut the overlying photoresist mask. In another embodiment, Fig. 7, after aperturing the thick oxide, very thin oxide is regrown in the aperture, itself apertured centrally, and a base contact 32 deposited in the aperture. A photoresist mask 33 after development is baked so that it plastically flows to produce graded edges 6 and ion implantation effected as before but with the partial masking effect of the contact 32 providing a self registered contact region. Electrodes are then provided substantially as above. Reference has been directed by the Comptroller to Specification 1,294,515.

Title: Broad line seismic profiling using simultaneously radiating sources
IPC: G01V1/00
Filed: 1972-07-21
Abstract: 1423366 Seismic exploration SEISCOM Ltd 18 July 1973 [21 July 1972] 34164/72 Heading H4D In seismic reflection profiling, vibratory sources are offset laterally from a line of profile and are actuated simultaneously but on respective different frequency bands of a desired transmission spectrum. This enables the individual contributions of the sources to the resulting composite recorded reflection signal to be identified by frequency discrimination so that the cross-dip of subsurface strata can be determined. Examples of roll-along profiling methods using a line of sources transverse to the profile line and providing multiple coverage of common depth points are given. The allocation of the frequency bands to the different sources is changed as the source line is advanced from one position to another in the profile line direction, whereby the complete spectrum is transmitted by any particular source over a series of actuations. At each source line actuation the composite reflection signal detected by a receiver array on the profile line is recorded in a conventional multi-channel recorder. These records are cross-correlated separately with the different transmission signals to obtain further records associated respectively with individual sources and individual frequency bands. The further records associated with a particular source are then summed to give a stacked record representing the full spectrum reflection signal for that source. Comparison of the stacked records for the different sources provides crossdip data which can be displayed in colour. The transmission signals may be narrow-band ones or frequency-swept bands. To prevent ambiguity in the cross-correlation process the simultaneously-transmitted bands may be selected such that they are not harmonically related, whereby harmonic distortion of the transmission signals does not result in such ambiguity. For narrow-band transmission the vibrators may advantageously be made to resonate.
