Title: Non oriented silicon-iron sheet stock and process of making it
Inventor: CARPENTER VICTOR WILLIAM
IPC: C22C38/02
Filed: 1959-05-27
Abstract: A process for the manufacture of nonoriented silicon-iron sheet comprises hot rolling to an intermediate gauge e.g. 0.07 inch a silicon-iron containing from 0.5% to 3.8% silicon, from 0.02% to 0.08% carbon, and not more than 0.5% aluminium the balance being iron, except for unavoidable impurities, pickling the hot rolled material, cold rolling it to final gauge e.g. between 0.014 and 0.025 inch without intermediate annealing, and then annealing at a temperature of 1950 DEG  to 2200 DEG F. in a decarburizing atmosphere thereby removing a part of the carbon therein, while leaving a total carbon content in excess of 0.01%, and then pickling the stock, the said stock being susceptible to further decarburization after punching into laminae in an annealing treatment in a decarburizing atmosphere at a temperature of 1400 DEG  to 1700 DEG F. to a total carbon value of less than 0.01%.  The first annealing is carried out in an atmosphere oxidizing to iron and silicon.  In an example the annealing is carried out on a siliconiron containing from 1.5% to 2.0% silicon and not more than 0.03% carbon which produces a phase change fom gamma to alpha iron at the surfaces of the material, the said phase change resulting in the production of new grains of columnar form at said surfaces and in which the second annealing treatment produces an enlarged grain size as a derivative of said columnar grams.  Stock having magnetic properties not completely developed and not yet subjected to the second annealing operation may be sold as semi-processed stock and the purchaser carries out the second anneal to fully process the stock after he has stamped out the required laminae.  Specification 558,558 is referred to.

Abstract: 994,213. Semi-conductor devices. WESTERN ELECTRIC CO. May 18, 1961 [May 24, 1960], No. 18160/61. Heading H1K. A solar radiation photo-cell consists of a layer of semi-conductive material of one conductivity type sandwiched between layers of opposite type so as to form two PN junctions, the depths a and b of the junctions from the energy receiving face being so chosen as to maximize the expression where # = b/L and # = a/L, L being the minority carrier diffusion length of the semiconductor material. Fig. 2 shows a plot of F(s) against s where s = x/L, x being the depth below the surface of a junction. F(#) is the value of the function when n = b and F(#) is the value when x = a. In practice, the first junction will be at a convenient depth so that a is known and hence F(#) is known. By inserting this value of F(#) in the equation and maximizing b can be found. In the arrangement shown in Fig. 1, a wafer of mono-crystalline silicon has PNP regions 12, 13, 14. Junctions 15 and 16 are respectively 10<SP>-4</SP> and 3À2 x 10<SP>-4</SP> cms. respectively from the surface 26. Ohmic contacts 19, 21 and 22 are provided and those (21, 22) joined to the P regions are joined together. Region 14 is thickened to give strength to the device. The arrangement of Figs. 4A and 4B consists of a P region 33, an N region 34 and a P + region 35. The P and P + regions are connected by small tube-like portions 38 of P- type material. Ohmic contacts 39, 40 are connected to the P and N regions. During manufacture a P-type silicon crystal is covered with an oxide coating. One face is then sprayed with wax through a mask containing an array of holes and the remaining surfaces except for a portion of the opposite face are covered with wax. The oxide coating is then removed from the unwaxed areas and the wax itself is then removed. The device is then heated in an atmosphere of phosphorus vapour to provide the N-type layer and the oxide is removed. Subsequently, the device is heated in an atmosphere of B 2 O 3  to produce the P+ layer connected to the P layer. Specification 782,603 is referred to.

Title: Improvements relating to coin counting and packing apparatus
IPC: G07D9/06
Filed: 1930-06-13
Abstract: 352,208. Counting and packing coins. AEG - FAHRKARTENDRUCKER GES., Hennigsdorf, Osthavelland, Germany. June 13, 1930, No. 18227. Convention date, June 13, 1929. [Class 94 (i).] In an apparatus for counting and packing coins, on adjustment of a scale marked for various coins, the number of coins to be counted and packed is determined and the distance of the package carrier from the sealing means and the coin shoot is also adjusted. A crank 5, Figs. 1 and 2, is rotated until a pin 6 engages one of a number of holes 3, each of which is marked for coins of a particular value. A toothed wheel 9 is thus rotated and operates a rack 10 so as to move a table 12 and a container 48 to the required distance from the sealing device (not shown) and a feed shoot 51, corresponding to the number of coins which have to be packed. A cam 18 is simultaneously rotated, so that a rack 19, moving in the direction of the arrow, Fig. 2, rotates a spindle 22 and winds a spring 25; while two toothed segments 29, 28 are also rotated, the latter so that a number of teeth corresponding to the adjustment of the crank 5 pass the cam 43. Each coin, before passing to a container 48 through the hole 50 and shoot 51 rotates a counting wheel 42 and the cam 43 through a distance equal to one tooth so that after the passage of sufficient coins, the cam 43 moves the segment 28 and therefore the segment 29 through one tooth. When a projecting tooth 30 comes in contact with a pivoted lever 31, the spring 25 is released and returns the members 28, 29, 19 to their former positions. In order to allow time for this return movement, a pin 34 on the lever 31 engages a recess in a pawl 35 until the lever 31 coming into contact with a coupling 47 causes a spindle 46 and a plate 39 to rotate so that a pin 40 moves the pawl 35 to release the pin 34 ; under the influence of the spring 31a the lever 31 then returns to engage the segment 29. A plate 13 is simultaneously rotated to bring a fresh container beneath the coin shoot, and to bring the filled container above the discharge aperture 53. Specification 335,593, [Class 94 (i), Packing &c.], is referred to.

Abstract: 1,028,877. Transistor switching circuits. SQUARE D CO. May 1, 1964 [May 1, 1963], No. 18293/64. Heading H3T. [Also in Division H2] A circuit T for timing the various operations of a welding process comprises a capacitor 44 which during its charging periods can be sequentially associated with any one of resistors R2-R5 in an OR module and which is provided with a circuit including a NOR unit N14, a diode D1 and a resistor R1, whereby the capacitor can be rapidly discharged. When a terminal IT2 receives a " 0 " signal the NOR unit N14 is non-conductive and the capacitor 44 charges from a common positive supply COM over a circuit including terminal IT1, terminal OOR1 in the OR module, one of the diodes D2- D5 and one of the resistors R2-R5. When the voltage across the capacitor 44 reaches a given value Zener diode ZD breaks down and a signal is applied to NOR unit N15 to change the signal appearing at the output terminal OT1 of the NOR memory N15, N16. This change of signal is transmitted to the input terminal IT2 thus rendering the NOR N14 conductive to establish the discharge path for the capacitor 44. The particular one of the resistors R2-R5 associated with the charging of the capacitor 44 at any given operation in the welding process is selected by the appearance of a " 1 " signal at each of the diodes D6-D14 associated with a junction 48 or 50 or 52 or 54.

Apparatus for amplifying and reshaping telegraph pulses comprises a magnetic core having a rectangular hysteresis loop, input and output windings and a third winding fed with a scanning waveform consisting of a saw-tooth followed by an arcuate pulse of opposite polarity. As shown, bipolar pulses a (Fig. 2) are fed from line 3 to the input winding 2 of the core 1 and higher frequency scanning pulses b are fed to winding 26. These pulses have a waveform c (shown on a much larger scale) such that effective positive pulses are developed in winding 5 when the leading edge of each positive pulse c coincides with a negative input pulse a and effective negative pulses are developed in winding 5 when the leading edge of each negative pulse c coincides with a positive input pulse a. Winding 5 is biased by a potential divider 7, 8 so that small amplitude pulses developed during the lower speed parts P1, H1 of the waveform c, have no effect on the bi-stable circuit comprising transistors 12, 13, the bias being overcome by the effective pulses at times such as t 1 , t 2  so that the bi-stable circuit is switched, thus providing an improved version of waveform a. It is explained how the arcuate parts H1 prevent the circuit responding to pulses a having an amplitude insufficient to switch the core 1. The circuit may be operated with single-current input pulses if a bias current is fed to winding 38. Generating modified saw-tooth waves c.-The leading edge of each half cycle of a square-wave from an astable multivibrator comprising transistors 20, 21, turns on diodes 35 and 32 or 30 and 31, allowing capacitor 28 to discharge via winding 26 and recharge with opposite polarity, giving a saw-tooth waveform such as P1. The overshoot in inductor 27 gives the arcuate part such as H1.
