Title: Improvements in broad area transistors
Inventor: SANDIFER ERIC GERALD
IPC: H01L29/00
Filed: 1956-12-12
Abstract: 853,575. Transistors. BRITISH THOMSONHOUSTON CO. Ltd. Dec. 11, 1957 [Dec. 12, 1956], No. 37960/56. Class 37 A junction transistor is produced by alloying an impurity into a semi-conductor body of one conductivity type to produce a first PN junction, removing the unalloyed impurity by dissolving it in a chemical reagent such as mercury, alloying a second impurity into the first recrystallised layer to produce an NP junction and providing conductors to (i) the body,(ii) the first recrystallised layer and (iii) the second impurity element. Etching is carried out after the second, or each alloying step to remove short circuiting material. The semiconductor may consist of germanium with indium as the first impurity, which is dissolved in mercury, the amalgam being removed by nitric acid. Arsenic, antimony and phosphor may also be used as the second impurity. Fig. 3 shows the completed transistor comprising the N-type body portion 1, the first recrystallised P-type layer, the second recrystallised N-type layer 8 and second impurity body 6. Connection to basic element 10 of copper or fernico (which constitutes the collector) is made by tin solder 11, contact 13 to layer 8 being the emitter and contact 12 the base electrode.

Patent GB-847147-A (GB)
Title: Improvements in or relating to the finishing of polyester fabrics
IPC: D06Q1/00
Filed: 1957-12-11
Abstract: Fabrics consisting of or containing linear aromatic polyester fibres are subjected to high pressure at elevated temperatures, so as to deform the cross-sections of at least part of the fibres, then to an intermediate heat-setting treatment, and finally to an alkali treatment, so that the cross-sections of the deformed fibres finally resemble that of natural degummed silk. Preferably the fabric consists of or contains a major proportion of polyethylene terephthalate fibres, but it may consist of or contain linear aromatic copolyester fibres, including copolyesters containing sulphonic acid or sulphonate groups.  Deformation of the fibres may be achieved by calendering the fabrics with smooth rolls or Schreiner rolls, preferred conditions comprising treatment at fabric temperatures of 100-450 DEG  F., especially 100 DEG -350 DEG F., under pressures of 0,12-2 tons per linear inch, expecially 0,2-0,8 tons per linear inch, pressure being applied uniformly over the whole surface area.  The alkali treatment may be carried out in aqueous alkaline solution in such a manner that the fabric loses at least 5% of its weight, preferably 5-25%, and the concentration of alkaline material in the bath may be at least 2% based on the bath weight, alkali-metal hydroxides (especially sodium hydroxide) being preferred, although alkaline-earth metal hydroxides and salts of alkali metals with weak acids (e.g. sulphides, sulphites, phosphates and silicates) may also be used.  The intermediate heat-setting treatment may be carried out at 250 DEG -450 DEG F. by application of dry heat, with the fabric relaxed or unrelaxed.  If desired the fabric, after the application of the pressure treatment, may be soap scoured at the boil while free to shrink, and dried.  In an example, a plain weave fabric of polyethylene terephthalate yarn is scoured with soap, dried, and then calendered at 300 DEG F., 0,5 ton per linear inch pressure and 25 yards per minute fabric speed.  The fabric is then heat-set on a pintenter at 440 DEG F. for one minute with 5% overfeed in warp direction and two inches under width.  It is then immersed for 5 mins. in boiling 3% by weight caustic soda, at a liquor to goods ratio of 50 : 1, and is then rinsed, washed with 1% acetic acid, re-rinsed, and dried.  The fabric loses 25% of its weight during the alkali treatment.  Fabrics treated according to the invention show enhanced aesthetic properties as, e.g., hand, drape, scroop and rustle, suppleness, surface dryness, liveliness, lustre and surface cover.

Title: Improvements in or relating to a container-to-carrier fastening apparatus
IPC: B60P7/13
Filed: 1959-11-13
Abstract: 914,368. Securing freight containers to vehicles. NATIONAL RESEARCH CO. Nov. 13, 1959 [May 4, 1959], No. 38597/59. Class 78 (4). A fastening for attaching a freight container 10, Fig. 2, to a platform 6 of a vehicle, comprises members 9 and 5 attached respectively to the container and the vehicle and a key 11. As the key 11 is inserted to lock the members 9, 5 together it is rotated so that a lug 11b which is eccentric on the shaft of the key follows a guideway within the two members and comes to rest behind a wall 51 of the member 5. The key may be withdrawn from both members or merely moved to an unlocked position in which it is withdrawn from the member 9. Surfaces 19, 20, serve to guide a sloping face of the member 9 into its correct relationship with the member 5. The sloping face of the member 9 may also co-operate with guide structures in the hold of a ship. Fig. 9 shows how a pair of anchor members 5 may secure containers A, B to the vehicle 6, similar members 5a being used on opposite corners of the containers. The adjacent corners of the containers are secured to members 61, which are similar to a pair of members 5, 5a joined together. In a second embodiment, two members 9, 62, Fig. 10, attached respectively to a container 10 and a vehicle 63 are locked together by means of a detachable member 68 and a key 86. A tongue 75 of the member 68 engages with the member 62 and is held in engagement therewith by a latch 78. The top part of the member 68 engages a recess within the member 9 and the key 86 passes through members 9 and 68 to lock them together. When the key 86 is inserted the latch 78 cannot be withdrawn. The key 86 is provided with an eccentric lug which must be rotated in moving the key from its locked to its unlocked position. In a third embodiment, Fig. 15, a member 9 attached to a container 10 is secured to a member 91 attached to a vehicle 90 by a key 95. An eccentric lug 95b is spring-urged into engagement with a recess in the interior of the member 9 when the key is in its locking position. The key 95 must be pushed inwardly and turned before it can be moved to its unlocked position. The same member 9 is used in all the embodiments described.
