Filed: 1971-04-19
Abstract: 1319732 Stud and socket fastenings S W BENGTSSON 19 April 1971 [13 April 1970 16 Nov. 1970] 26205/71 Heading E2B A resilient fastener for interconnecting tent cloths or the like comprises two identical heads 10 which are rigidly interconnected by a rivet 19 or are integral and project in opposite directions from a central grooved anchoring portion each head having a neck groove 13. Each head may have one or more slots 12 to provide resilience. When the fastener is formed integrally the central hollow portion is rendered non resilient either by a central web or by a plug inserted therein after connection. The solid fastener shown in Fig. 13 is made of a rubber-like plastics the resiliency of which makes a slot in the heads unnecessary. When the central portion has a central web to render it non resilient the eyelet is secured thereto by clamping it to reduce its diameter.

Abstract: 889,958. Parachutes. BARISH, D. T. Aug. 15, 1958 [Sept. 16, 1957], No. 26334/68. Class 4. An autorotating parachute includes a canopy formed of substantially triangular panels of flexible material secured together at their narrower ends, which are held in position in planes extending substantially parallel to the central axis of the canopy, and spaced apart at their wider ends adjacent the skirt of the canopy, 7 the panels being shaped and contoured out of the flat toprovide each with both a longitudinal and a transverse camber. Fig. 1 shows the major part of a panel blank 10 stamped or cut from flat sheet material having a porosity of not more than two feet per second at two inches of water pressure differential; Adjacent edges 13 and 14, 21 and 22, 23 and 24, and 25 and 26, are then stitched together to form a panel cambered both parallel to and perpendicular to the line of symmetry. The blank 10 may be formed from two pieces of material connected back to back along the line of symmetry of the finished blank. Four such panels form the canopy, Fig. 4, being attached by peripheral ties 34. Each panel is twisted so that at the apex, the panel lies in a plane parallel to the vertical, the edges 16 being uppermost. Each panel is attached at the apex by stitching to the adjacent panel and to a central shroud line 33. The remaining shroud lines 35 depend from the ties 34, being connected thereto at points nearer the extremities 18 of edges 16 than the extremities 17 of the remaining edges. All the shroud lines are connected to the load through a swivel joint. Interpanel lines 36 connect the panels and are located at one half to three quarters of the distance from the apex to the skirt. The central shroud line 33 " dimples " the apex and during descent the parachute autorotates. To pack the parachute, light lines are used to draw lines 36 into loops extending out of the canopy away from the load. The swivel joint, shroud lines, canopy, looped lines 36, and the light lines are then packed in that order. On deployment, the light lines pull the looped lines 36 from the pack first, ensuring no tangling of the canopy and lines, the light lines being broken by development of the canopy or the weight of the load.

Title: High power avalanche diode and methods of making the same

Filed: 1970-06-02
Abstract: 1277138 Semi-conductor devices RCA CORPORATION 2 June 1970 [12 June 1969] 26489/70 Heading H1K A high power avalanche diode is manufactured by epitaxially depositing a uniformly low carrier concentration N-type layer 14 at least 6 Á thick on to a high carrier concentration N + -type substrate 12 and diffusing an acceptor dopant into the layer 14 to form a P-type layer 18 defining a PN junction 20 with the layer 16, which junction is at least 3 Á from the substrate 12. The P-type layer 18 is diffused from a layer containing a high concentration of the acceptor; e.g. B in a Si or Ge device, diffused from a deposited layer of boron silicate or boron nitride. The former material may be deposited by pyrolytic decomposition of a gas comprising trimethylborate and ethyl silicate while the latter material may be deposited by evaporation of a boron nitride source. The dopant source layer is finally removed by grinding or etching. In an alternative method a shallow preliminary highly B-doped layer is produced in the surface of the N-type epitaxial layer 14 by diffusion from a deposited layer of boron silicate or boron nitride and, after removal of the latter, a drive-in diffusion step is carried out to form a relatively shallow P-type layer 18. In this case the contact to the P-type layer 18 may be attached to a heat sink. In both processes the heating step which forms the P-type layer 18 also causes a narrow portion of the remaining N-type material 16 immediately adjacent the substrate 12 to have a graded dopant profile due to redistribution of dopant from the substrate 12.
