Abstract: 1310942 Platinum-doped silicon devices TRW Inc 7 May 1970 [11 Aug 1969] 22166/70 Heading H1K In the manufacture of a silicon device containing at least one pn junction the silicon body is heated in the presence of platinum to a temperature in the range 925-965 C. for a time sufficient to diffuse platinum throughout the body in substantially uniform concentration. Platinum is thought to provide holespecific carrier recombination centres. Planar diodes and transistors (which may form part of integrated circuits), completed except for the application of electrodes, are treated by evaporating or sputtering platinum on to the lower and/or side faces of the semi-conductor body and by diffusing-in the platinum; the device electrodes are then applied by any conventional process. The claims are to transistors only.

As shown in Fig. 1, a device for locking a tool 6 in a pneumatic hammer comprises a lock 18 rotatably mounted at the end of a barrel and a cover 16 attached to the casing. The shank of the tool has a portion 6c corresponding to the outlet end 23 of the hood 16 and a portion 6b corresponding to the outlet portion of the lock 18. The tool is prevented from moving out of the lock 18 by rotation of the lock relative to the barrel 5 and cover 16 so that the cross-sections 6b and 20 do not correspond. This rotation is performed by a pin 27 mounted on a sleeve 26 rotatable on the cover 26, which pin engages in an axial slot 29 in lock 18. The pin may be held in the locked position by a leaf-spring which engages in a notch 32 in a raised portion 31 on the casing. Several modifications are described in which the angular position of the tool can be located in two discrete positions or can be infinitely variable during working.

Title: Electrical machine rotor
IPC: H02K1/30
Filed: 1977-05-26
Abstract: The rotor (2) contains a carrier cylinder (13) with superconductive coils (15), which is in each case connected at its two end faces to an end flange (3a and, respectively, 4a) mounted on a shaft section (3; 4). It should be possible to compensate easily for the shrinking of the carrier cylinder occurring during a cooling of the superconductive coils and, nevertheless, to keep the introduction of heat into the coils low. For this purpose, it is provided that the carrier cylinder (13) is mounted at one end flange (3a) via a radially arranged laminated annular plate (18) of thin annular-disc-shaped metal layers and rigidly at the other end flange (4a) via a connecting element (25), the effective length of connection of which is greater than its axial dimension. Such rotors can be provided, in particular, for high-power turbo generators. <IMAGE>

A lock of the kind used on attache cases, suitcases and the like has a turn knob slidable to retract the bolt 2, a part 6 of the knob being rotatable to a safety position in which retraction of the bolt is prevented by the knob indicating means to give an audible click then the knob is turned to the safety position. The lock has a flanged case 1 provided with bentover prongs by which it may be attached to the attache case, suitcase or the like. The knob is on the front of the case and has a central keyhole portion 4 attached by bent-over lugs 5 to the bolt 2, the turn part 6 surrounding the keyhole portion and being rotatable through 90 degrees. The part 6 is formed with two ears 7 and when the ears are positioned transversely of the case the bolt can be drawn back if unlocked. When the part 6 is rotated through 90 degrees one of the ears abuts against a rib or platform 9 pressed up from the case 1 and movement of the knob is prevented. When the part 6 is turned to this latter position the audible click is given when it reaches the position and housed in one of the ears 7 of the part 6 is a spring pressed click member 10 which enters a hole 11 in the top of the case and so makes the click. The click member comprises an arcuate portion 12 housed in the rim 13 of the part 6 and a portion 14 which extends into the ear and which is formed with a dimple 17 to engage the hole 11.

When R is samarium and M is cobalt, the sintering may be carried out at 1025-1150‹C., in a helium atmosphere in presence of yttrium as getter. Other getters specified are thorium, zicronium, calcium and rare earth metals. Cooling may be effected at 100‹C. /minute, and the magnetizing field may be 100, 000 Oc. The permanent magnetic particles may be magnetically orientated prior to sintering to produce an anisotropic sintered body. In an Example, magnetically orientated particles of SmCo 5  (3À09) and Sm 2 Co 7  (1À69) are sintered at 1050‹C. for 1 hour in helium. The product consisted solely of SmCo 5  In another Example, GdCo 5  is produced.

The sleeve 16, secured to the two-ringed carrier 20, 21, is connected through a one-way detent 36 and a multidisc brake 38 to the casing 19 of the gearing. A multidisc clutch 41 can be engaged to couple the casing 11 directly to the shaft 12. The shaft 12 and the sleeve 14 are connected through dog clutches (not shown) to a common output shaft. The gearing acts substantially as described in Specification 910,003 to give direct drive, by engagement of the clutch 41, a reduced ratio by stationing the sleeve 14, and reverse by clutching the sleeve 14 to the output shaft and applying a brake band 39 to station the carrier 20, 21. By releasing the multidisc brake 38, the carrier 20, 21 rotates freely in both directions and prevents idle drag in the torque converter being transmitted through the gearing. Speed and/or torque-sensitive means (not further described) are provided for engaging the brake 38 and the clutch 41, so that changes of ratio for forward drive are produced automatically, manual selection being required only for establishment of forward and reverse drive.

A lead-through capacitor has a thin flexible strip of dielectric material 12 wound on to a tubular insulator 11. The strip is metallized to form the capacitor electrodes so that areas of one polarity extend to one end of the roll and areas of the other polarity extend to the other end. This may be effected by dividing the metallized surface into two series of electrodes with an unmetallized band giving a castellated pattern as described in Specification 647,573. Connections are made by an internal eyelet 18 and an external eyelet 13 which make contact with the electrodes at the ends of the roll. The roll ends may be sprayed with metal and the eyelets soldered thereto. The dielectric material may be polyethylene terephthalate and may be vacuum dried and heat treated after winding. Specification 811,984 also is referred to.

Chromium, depositing; preparing surfaces. - Articles having a mirror-like or other prepared surface are made by treating the foundation metal by buffing or polishing or by scratch-brushing to produce the desired surface and then electrolytically depositing a bright layer of chromium thereon. No treatment is necessary after plating. When the foundation metal is hard, e.g. steel, it may be coated with a softer metal such as copper before the surface treatment. For a bright deposit of chromium to be obtained the temperature must be between limits dependent on the nature of the electrolyte and the current density employed. Graphs are supplied showing the relation between temperature and current density for an electrolyte containing 500 gms. chromic acid and 5 gms. sulphuric acid per litre and for an electrolyte containing 250 gms. chromic acid and 2.5 gms. sulphuric acid per litre. For the former electrolyte a temperature of 30‹ C. and current density 0.5-0.75 amp. per sq. inch are suitable. The deposit may be 1/2000 to 1/1000 inch in thickness.
