Abstract: An acylated glycoside of a b -(3-hydroxycyclopentanophenanthrene) - D a  : b  - butyrolactone in which an aldose nucleus is linked through a b -pyranoxide ring to a cyclopentanophenanthrene nucleus is obtained by reacting, in the presence of a dehydrating agent, e.g. anhydrous magnesium sulphate, an acyl-a -aldose selected from acylbromo-a -aldose and acylchloro-a -aldose with a b -(3-hydroxycyclopentanopolyhydrophenanthrene- D  a  : b -butyrolactone.  The product may be deacylated by treatment with a metal alkoxide, e.g. barium methoxide in alcohol.  The b -aldose or acyl-b -aldose residue of the products may be derived from any a -aldose having a b -pyranoxide ring in which the substituents on the second and third carbon atoms are in trans-relation to each other. The p - (3 - hydroxycyclopentanopolyhydrophenanthrene)- D  a  : b -butyrolactone employed as starting material may contain unsaturated bonds in the nucleus and further substituents, e.g. periplogenin, digitoxigenin, gitoxigenin, digoxigenin, strophanthidin, sarmintogenin, monoanhydrothevetigenin and a - and b -monoanhydroouzarigenin.  Detailed examples are given.  The Specification as open to inspection under Sect. 91 comprises also the preparation of compounds in which the aldose nucleus is derived from a monosaccharide.

Title: Semiconductor devices
IPC: H01L21/316
Filed: 1966-05-31
Abstract: 1,126,406. Semi-conductor devices. RADIO CORPORATION OF AMERICA. 31 May, 1966 [22 June, 1965], No. 24031/66. Heading H1K. [Also in Division C7] Metal contacts to a semi-conductor device are made by depositing nickel or cobalt on the semi-conductor and aluminium on the nickel or cobalt. The nickel or cobalt is deposited by electroless plating and the aluminium by evaporation. Figs. 1 to 5 (not shown) depict successive stages in the manufacture of an insulated gate field effect transistor in which the source and drain contacts are of aluminium on nickel. First, two N regions of circular, polygonal or irregular shape are diffused through a surface oxide mask into a P silicon wafer. This mask is then replaced by one with smaller apertures through which nickel is deposited from an alkaline nickel chloride solution of specified constitution. After heating in nitrogen to sinter this nickel layer, more nickel is deposited, the wafer is re-heated in hydrogen to form a channel layer under the oxide, and aluminium is then evaporated on to the entire wafer surface. Most of this aluminium is subsequently removed to leave only source and drain contacts consisting of aluminium-on-nickel and an aluminium gate contact on the oxide. The contacts are subsequently provided with leads and the device encapsulated in a sealed unit. In a second example the above process is followed but with silicon-germanium alloy in place of silicon and cobalt in place of nickel.

Title: Improvements in apparatus for opening hinged boxes for filling and the like
IPC: B65B43/38
Filed: 1928-08-29
Abstract: 313,812. United Cigarette Machine Co. Akt.-Ges., and Gottschalk, P. Aug. 29, 1928. Filling materials into hinged boxes.-In apparatus for opening hinged boxes preparatory to filling, clips 2, Fig. 1, on endless chains 2<a> feed the boxes to position A against a stop 5. At this point, the clips disengage the box by passing over a sprocket 3b, and a lever 4 pivoted at 4<a> is turned by a cam 3 to hold the box fixed against the stop. In this position, the lid 1<a> of the box is pressed against a fillet 7 on a lever 9 pivoted at 9<a> at one or both sides of the apparatus. The fillet may be surfaced with rubber, plush, &c., or studded with points 8, so as to engage the edge of the lid. The lever 9 is now rotated into the position shown in broken lines, carrying the lid with it into the open position. A guide 15 acts on a roller 14 to raise the fillet out of engagement with the lid, and a spring 16 passes laterally against the lid to beep it open. The bearing of the pivot 9<a> is adjustable so that it can be set to coincide with the hinge of the lid. After opening, the box is fed away for filling &c. at right angles to its previous movement, a guide 18 maintaining the lid in position. In the form shown in Fig. 5, the pivot 9<b> of the lever 9 is arranged slightly above the axis of rotation 7<b> of the lid, so that, on rising to the open position, the fillet 7 is gradually disengaged from the lid. A spring bolt 20, arranged in a frame 22 attached to the fillet engages beneath the lid and holds it in the open position. In a similar form, the fillet is spring-mounted and is made to describe the same arc a by means of a curved cam surface, the axes 7b, 9<b> being co-incident. In order to prevent the box body from being raised with the lid during the opening process, the box may be held between a guide 23, Fig. 7, and a slide 26 with points 34. As soon as the box-opening device 9 operates, a slide 25 is pushed to the left to overlie the box body and prevent it from rising. The slides are operated from one cam 28, a lostmotion device 32, 33 permitting the slide 25 to come into action before the slide 26 disengages.

Class 120(2) [Also in Groups VIII and XXXIX] A magnetic amplifier utilizes a minute current to close normally open contacts and so to bring into operation a greater current to actuate a device which operates a stop motion, upon occurrence of a fault or detected abnormality in the machine or its product. When contacts 1 are open, the current through winding 16 being opposed to that through winding 18, the core of a magnetic amplifier 5 is unsaturated, the impedance of windings 12 in the A.C. supply to rectifiers 17, 9 is thus comparatively high and the current through the winding 8 of a relay is insufficient to operate contacts 6 and 7. When contacts 1 are closed by the presence of a fault, winding 13 is placed in circuit with a rectifier 14 and the increased magnetization of the amplifier core lowers the impedance of windings 12. The current through winding 16 and hence the magnetization of the core are thus increased, the impedance of the coils 12 is further lowered and finally the current through winding 8 is sufficient to close contacts 6, 7 to energize a solenoid 2 which stops the machine and to light a warning lamp 21. The lamp 20 is alight whenever the transformer primary 23 is connected to A.C. supply.
