Title: Improvements in methods of producing semiconductor bodies for transistors and the like
IPC: C30B31/02
Filed: 1959-03-03
Abstract: 843,168. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 3, 1959 [June 4, 1958], No. 7337/59. Class 37. In a method of producing semi-conductor elements, a body of semi-conductor material is heated in an oxidizing atmosphere to form a coating containing a conductivity directing impurity (step 1), further heated so that the impurity diffuses into the body (step 2), etched to remove the oxide (step 3) and bisected to form two elements. In example 1 P type Ge wafers are heated to approximately 100‹C. and exposed to SbCl vapour in room atmosphere so that the SbCl  5  hydrolyzes to deposit Antimony Oxide on the Ge surface, further heating causes the Sb to diffuse into the Ge to the desired depth and the Antimony Oxide is removed by etching in either HCI or HF. In example 2 P type Ge wafers are heated to approximately 600‹C. while As vaporized at 100‹C. to 200‹C. oxidizes and sublimes As 2 O 3  on to the surface of the wafers, the wafer temperature is raised to 600‹C. so that the As diffuses into the Ge to the desired depth and the wafer is etched on HCl acid to remove the As  2 O 3  coating. In a transistor Fig. 2 using such an element the original Pregion forms the collector, the diffused N region is the base and a P type emitter is formed by alloying techniques with Pb and Ga or In and Ga.

Title: Winder devices in sewing machines for filling bobbins with thread
IPC: D05B59/00
Filed: 1967-02-16
Abstract: 1,144,974. Sewing machines. NECCHI S.p.A. 16 Feb., 1967 [18 March, 1966], No. 7391/67. Heading D1G. In a sewing machine a bobbin-winding shaft carrying a friction wheel is journalled on a support movable from a rest position to a working position in which the friction wheel contacts rotatable means of the machine releasably connected by coupling means to the main shaft of the machine, and a control means has a first portion operatively connected with the support, and a second portion operatively connectible with a control element of the coupling means. A pulley 32, driven by a belt 31, is journalled on a sleeve 34 fast with the main shaft 30. A sleeve 42, journalled on internal surfaces provided on pulley 32 and sleeve 34, anchors one end of a helical spring (43) which is tightly wound upon aligned cylindrical surfaces provided internally on pulley 31 and sleeve 34 for coupling the latter together. If rotation of sleeve 42 is checked, spring (43) unwinds to uncouple sleeve 34 from pulley 32. A support arm 11, pivoted on a pin 13, journals a bobbin-supporting shaft 15 fast with a friction wheel 16. A lug 19 on arm 11 normally has its upper surface 23 engaged by a leaf spring 20 to bias arm 11 counterclockwise. Also pivoted on pin 13 is a two-armed control lever 24, one arm 25 of which carries a handle 28 and the other arm 26 of which carries an L-shaped bracket 29 engaging arm 11. Arm 26 also carries a pin 54 which normally engages a flat surface 52 on a lug 51 at the free end of a pivoted arm 49 biased upwardly by a spring 50. If lever 24 is turned clockwise, bracket 29 shifts arm 11 to engage wheel 16 with a friction surface 55 on pulley 32. Spring 20 then engages the lower surface 22 of lug 19 to maintain wheel 32 and surface 55 engaged. Pin 54 simultaneously engages an inclined surface (53) on lug 51, thereby allowing spring 50 to raise arm 49 for engaging a brake block 47 thereon with a peripheral groove 48 in sleeve 42 to uncouple sleeve 34 from pulley 32. The fully-wound bobbin engages a fixed abutment 56, whereby wheel 16 is separated from surface 56 which sleeve 34 remains uncoupled. Positive transverse pressure on spindle 15 is required to overcome the bias of springs 20 and 50 for returning arm 11 and lever 24 to their initial positions.

Abstract: 1410101 Wells &c BAKER OIL TOOLS INC 15 Feb 1973 [13 April 1972 5 Sept 1972 3 Nov 1972] 7393/73 Heading E1F A subsurface safety valve has a valve member moved from closed to open position by a control fluid, a bypass valve being operable by the control fluid to equalise the pressure over the member prior to the movement. The valve has a body 136 and is the upper of a pair of valves in an assembly for a dual-completion, sub-aqueous well, the control fluid entering the top of the body, flowing to a chamber 195, and passing to the lower valve through a conduit 173. The valve member 176 is installed in the body through an opening 207 having a closure 208 forming a guide for the tubing 140 for the lower valve. The member 176 has slots 215 engaged by pins 213, 214, is held in the closed position by a spring biassed sleeve 178 which is also acted upon by well fluid pressure, and is moved downwardly and rotated to the open position by the pressure of control fluid in the chamber 195 acting on a sleeve 185. The slot is shaped so that limited vertical movement of the member is permitted at the open and closed positions without rotation of the member. A spring urged seal 202 mounted on the body engages the member in the closed position. Apertures 225, 226 in the bore of the body 136 are respectively connected to chambers 242, 229 (Fig 9) in the bypass valve 220 so that an increase in the pressure of the control fluid as it flows from the chamber 195 through a port 248 to the lower valve operates the valve 220 to connect the apertures and equalises the pressure over the member before it is moved to the open position. The member may be held open by engaging a tool with a sleeve 196 to move the sleeve 185 downwardly to open the member, a dentent 252 holding the sleeves down and the member in the open position.
