Title: Transferring rolled stock from finishing roll lines to cooling beds
IPC: B23Q7/05
Filed: 1963-09-16
Abstract: 1,033,817. Rolling. SCHLOEMANN A.G. Sept. 16, 1963 [Oct. 20, 1962; March 1, 1963], No. 36309/63. Heading B3M. [Also in Division B8] Two parallel roll trains, each with a finishing roll line and a cooling bed, are characterized by the feature that a cross-switch is fitted between the two finishing roll lines and the two cooling beds. Figs. 1 and 2 show a discharge roll train 1 for a finishing line (not shown), whilst 2 is the discharge roll train of another finishing line parallel to the first. Roll train sections 1a, 2a are connected to the roll trains 1, 2 to carry the rolled goods to roll trains 3, 4 with adjacent cooling beds 5, 6. Sections la, 2a rotate about axes 9, 10 so that the free end of section 1a can be swung into roll train 2 or the free end of section 2a can be swung into roll train 1 (Fig. 2). This rotation is achieved by hydraulic drawing mechanism 11, 12 acting on the sections la, 2a by means of draw rods 13, 14, angle levers 15, 16 on fixed pivots 15a, 16a and tie rods 17, 18. Fig. 3 shows a set-up whereby rolled material from either of two finishing lines 30, 30a may be directed to either cooling bed 38 or 38a by using switches 33, 33a, 37, 37a associated with fixed sections 35, 35a, 39, 40, 43 and 44 and a pivoted section E.

Title: Improvements in rheostats, potentiometers and similar regulating apparatus
IPC: H01C10/28
Filed: 1929-11-29
Abstract: 335,454. Contal, C., and Davidson, E. Dec. 3, 1928, [Convention date]. Variable resistances. -A rheostat potentiometer &c. consists of wire wound on an insulating ring, contact being made by a discmounted on a spindle moving in a cone, so that the disc rolls on the ring without slipping. The ring 6 on which the wire is wound is mounted in a housing 1 which carries a bearing for a spindle 14 having on its end an eccentrically mounted footstep bearing 12 which receives one end of a spindle 10 carrying the disc 11. The other end of the spindle 10 is mounted in a central bearing provided with a terminal 9 and carried on a plate 2 supported on pillars 3, 4 passing through slots in the disc 11 and insulated therefrom. As the inclination of the disc 11 is small the clearance left by the slots for the pillars 11 is sufficient to allow it to make a single revolution in contact with the ring 6 without slipping. The disc 11 may be resilient and may be mounted to revolve in the spindle 10. The ring 6 may be formed with a projection not covered by wire on which the disc 11 rests in its zero position.

Title: Refractory monosulphides of lanthanides and actinides
Inventor: DIDCHENKO ROSTISLAW
IPC: C01F17/00
Filed: 1961-10-12
Abstract: 924,976. Monosulphides of lanthanides and a ctinides. UNION CARBIDE CORPORATION. Oct. 12, 1961, No. 36640/61. Class 41. Refractory monosulphides of lanthanide and actinide metals, such as cerium, uranium and thorium, or mixtures thereof, are obtained by the electrolysis, in a substantially oxygen-free atmosphere, e.g. in argon, of a substantially oxygen-free melt containing at least one sulphide compound, and a lanthanide or actinide compound(s) wherein the metal(s) has a higher valency than that for the monosulphide; the system being rendered electrolyzable by the inclusion of a suitable electrolyte such as at least one fused metal halide, comprising a halide of alkali or alkaline earth metals or mixtures thereof, although the halides of the lanthanide or actinide metals may be suitable for this purpose. The lanthanide or actinide starting materials having a valency exceeding two, may be a halide, sulphide or halo-sulphide, or other oxygen-free compound(s) provided the non- metallic component does not interfere in the monosulphide formation reaction. Both the sulphide compounds and the halide compounds may be lanthanides or actinides. The electrolysis is generally insensitive to variations in temperature within the operable fusion range and the optimum applied voltage depends upon the composition of the melt: the current density is not critical over a wide range. From examples quoted the electrolysis proceeds at 850-950‹ C., at 3.5-5.0 volts, and 3.0-10.0 amps., delivering 10-18 amperehours of current. The residual salt electrolyte contaminating the monosulphide product is removed by distillation at 700-1000‹ C. under a vacuum of 1-10 microns pressure of argon, or it can be washed free of salt with water. In examples of melts of mixtures of fused salts, a combination of the higher sulphide of a metal, wherein said metals exercise a higher valency than in said monosulphide, with the chloride of that metal is electrolysed in solution with a fused salt electrolyte comprising sodium chloride or a eutectic mixture of sodium chloride and potassium chloride. Examples of higher sulphide and chloride mixtures are those of cerium, thorium, lanthanum, gadolinium, ytterbium and uranium. Alternatively a combination of an alkali sulphide with a higher valency lanthanide or actinide chloride and eutectic salt mixture electrolyte is cited. A further modification involves the treatment of a rare earth mixture of higher sulphides with the corresponding chlorides and sodium chloride to yield a mixed monosulphide product. A crucible assembly for the fusion electrolysis comprises a graphite (or steel) crucible with a centrally mounted stirrer of molybdenum, tantalum or steel acting as cathode. The anolyte and the catholyte are separated by a diaphragm of fused alumina or perforated molybdenum sheet and the crucible is surrounded by a protective atmosphere of argon.

Abstract: 1477467 Semiconductor devices SONY CORP 21 Aug 1974 [25 Aug 1973] 36748/74 Heading H1K In an anologue memory circuit a negative pulse-amplitude modulated (PAM) input signal to be memorized is supplied via a terminal 41 and electrode 6, Fig. 1, to an n type semiconductor region 2 and thence to an adjacent p type region 3. Negative charge of magnitude proportional to the amplitude of the PAM signal is stored in the region 3 and reverse biases a pn junction between the region 3 and an adjacent substrate layer 10, narrowing a channel region 38 and reducing the current between a grounded source electrode 5 and a drain electrode 7 measured in terms of a voltage at output terminal 42. Means are provided for discharging the region 3. In Fig. 1 these means comprise a p type oscillator region 4 in layer 10 supplied with positive blanking pulses via a blanking terminal 43 and electrode 8. Positive charge injected from the region 4 in response to the blanking pulse is collected by, and thus discharges, the region 3. In a modification (Fig. 5, not shown) the negative PAM and positive blanking pulses are supplied to a single terminal connected to both electrodes (6 & 8). Fig. 4 shows another modification in which the PAM input terminal 41 and n type region 2 are physically separated from the p-type storage region 3, the region 2 being located instead in a further p-type region 23 directly electrically connected to the region 3. This device otherwise operates in the same manner as that of Fig. 1, with the p-type emitter region 4 now being located in the n type island 12 including the regions 23 and 2, discharge of the region 3 being by carriers injected from the region 4, collected by the region 23 and transmitted directly to the region 3. In all embodiments the conductivity types, pulse polarities &c. may be reveresd.

Title: Apparatus for automatically sorting and properly orienting articles
IPC: B23Q7/12
Filed: 1961-10-13
Abstract: 944,668. Orientating inserts. GROOV-PIN CORPORATION. Oct. 13, 1961 [Nov. 4, 1960], No. 36850/61. Heading B8S. A device for orientating inserts having one end chamfered employs a plate 12 reciprocable by fluid cylinder 49. The plate 12 receives an insert from magazine 62 in an aperture 19 formed in the plate. If the insert falls, chamfered-end-first into the aperture, the insert drops part-through the aperture and makes contact between terminal surfaces 27, 35 which are positioned centrally beneath the magazine. This makes an electric circuit and operates cylinder 49 to move plate 12 to the left to permit the insert, still carried by the plate, to drop into shoot 42. On the other hand, if the insert falls from the magazine other-end-first into the aperture, it sits in the aperture at a higher level and fails to engage the terminal surfaces 27, 35. In this case, cylinder 49 is operated to move plate 12 to the right to drop the insert into shoot 43. Thus the shoots discharge the same article but in opposed orientations.

Abstract: 950,261. Protective footwear. J. P. HINDLEY. (F. B. Griswold). Sept. 29, 1962, No. 37001/62. Heading A3B. A safety boot has an instep guard in the form of articulated arched rigid strips in edgewise overlapping relationship. The articulated assembly 11 is enclosed in a leather case 9 with a foam rubber backing (not shown) and may be attached to the boot 1 as shown in Fig. 1 or may be incorporated in the tongue of the boot. Each strip 23 (Fig. 5) may be made of metal and has a raised portion 25 and a lower portion 27 connected by a shoulder 29. The edge 33 of the portion 25 is turned down and the edge 35 of the portion 27 is turned up so that when the strips are assembled by rivets 41 (Fig. 7) both surfaces have no sharp edges. The normal position of the strips is shown in Fig. 9 and excessive flexing is prevented in one direction (i.e. straightening out and forming gaps between the strips) by the portions 33 and 35 engaging with each other, and in the other direction (increasing the curvature) by the portions 31 engaging the shoulders 29. In the first embodiment as shown in Figs. 1, 7 the lower strips 43 are longer than the others and extend down to the sole, but in the second embodiment i.e. when the articulated assembly is incorporated in the tongue (not shown) the strips are of similar lengths.

Abstract: 1,263,950. Vibration damper. SINTEF. 25 July, 1969 [29 July, 1968], No. 37427/69. Headings B3B and B3C. A tool holding rod 1, for example a boring bar, comprises a damping mass 2 slidably mounted in a bore 6 having damping fluid 3 and a spring bar 4 which is slidably mounted in a sleeve 5. The arrangement can be tuned by varying the position of the mass 2 and/or the length of the spring rod from the end of the sleeve 5 to the mass 2. The sleeve 5 is adjustable in rod 1 and the mass 2 is centrally mounted by springs 14. A sealing cap 15 has an expansion tank which is to allow for volume changes due to movement of sleeve 5 and spring rod 4. In another embodiment the spring rod is replaced by rubber discs 24, 25 which can be loaded by discs 29, 28 which are attached to a hollow rod 27 and a rod 26 respectively. The rods extend out to actuating knobs 33 and 32 respectively for independent adjustment of the spring rate and the damping force. Rubber elements 38 allow for expansion. The damping mass 2 can be in the form of a generatrix modified according to Fig. 8 and following the dotted line α which will-provided the bore has the same shape-result in increased sensitivity to changes in the average gap width when the damping mass is positioned in the neighbourhood of its left end position and is given an axial displacement, than when the damping mass is positioned adjacent its right hand end position and given an axial displacement. Correspondingly a generatrix which follows the dotted line γ will result in the opposite effect. The full line generatrix # will result in a linear relationship between gap width and axial displacement. The stepwise rectilinear generatrix can be smoothed out to a wave shape while maintaining the above explained non- linear effect. Rod 26 may be hollow to transport cooling liquid or air.

Title: Improvements in or relating to the preparation of steroid derivatives
Inventor: BARTON DEREK HAROLD RICHARD
IPC: C07J5/00
Filed: 1959-11-06
Abstract: The invention comprises steroids having a hydroperoxy group attached to a tertiary carbon in an a -position to a keto group, particularly 17a -hydroperoxy-20-keto steroids of the 5a - and 5b -pregnane series which may further contain a 3-keto or 3-hydroxy group, nuclear double bonds and a 16b -methyl group, and also a process for the introduction into a steroid molecule of an oxygen function by treating a steroid having at least one enol group, nuclear or extra-nuclear, with molecular oxygen to form a hydroperoxy group on said steroid, which hydroperoxy group may then, depending upon its stability, decompose to an oxo group. The enolic steroid may be formed by enolising the corresponding keto steroid in a strongly basic enolising medium, e.g. a solution of an alkali metal tertiary alkoxide in a tertiary alkanol.  The oxygen may be used at normal or elevated pressure and preferably at a temperature between 0 DEG C. and 35 DEG C.  Reduction of the hydroperoxy group, e.g. by catalytic hydrogenation or chemical methods produces the corresponding hydroxy-substituted compound. Examples detail the application of the process to compounds of the pregnane, cholestane, lanostane and spirostane series.
