Patent GB-1022477-A (GB)
Title: Improvements in or relating to epitaxial deposition of semiconductor devices
IPC: C30B25/12
Filed: 1963-11-18
Abstract: A graphite article is given a coating of silicon carbide by heating the article in a vacuum to 1300  DEG C., passing trichlorosilane over the heated article to deposit silicon thereon, raising the temperature of the article to melt the silicon and produce a uniform coating and thereafter raising the temperature to 2000  DEG C. to cause the silicon and graphite surface to react to form the desired silicon carbide coating.  If desired, the silicon coating may be melted and cooled several times before being heated to 2000  DEG C. Preferably the said article is a plate and the treated plate may be used as a heating element and supporting member for wafers of silicon during the epitaxial deposition thereon of silicon by the decomposition of a vaporous silicon compound, e.g. trichlorosilane. The coating of silicon thus deposited on the wafer may be followed by a coat of boron by replacing the silicon compound with a boron compound e.g. BCl3.  When the boron coated wafers are maintained at 1200  DEG C. for 10 minutes, the boron diffuses into the previous silicon coating and produces a semiconductor device.ALSO:A graphite article is given a coating of silicon carbide by heating the article in a vacuum to 1300 DEG  C., passing trichlorosilane over the heated article to deposit silicon thereon, raising the temperature of the article to melt the silicon and produce a uniform coating and thereafter raising the temperature to 2000 DEG  C. to cause the silicon and graphite surface to react to form the desired silicon carbide coating.

Title: Improvements in endless track vehicles
IPC: B62D55/06

Title: Clocked memory cell
IPC: G11C17/02
Filed: 1972-10-03
Abstract: 1369724 F.E.T. memory cells ROCKWELL INTERNATIONAL CORP 3 Oct 1972 [4 Oct 1971] 45619/72 Heading H3T When a negative potential (1) on the plate 11 of a storage capacitor is to be read out to the data line 5, a negative read pulse # R  is applied to the other plate 18, so causing plate 11 to go even more negative and enable a F.E.T. 13 to conduct a voltage - V, with no threshold drop, to a F.E.T. 2 and the line 5. During the write period # W  (also Fig. 2, not shown) F.E.T. 2 conducts and charges a capacitor 8 and C10 to the 1 voltage (-25 V) less the threshold of F.E.T. 2, resulting in a stored voltage of about - 18 V. F.E.T. 9 is held on by -V(-25 V) at its gate. During a reset cycle # RS  F.E.T.2 is off, and plate 18 of C10 goes to - 25 V. This causes plate 11 to go to about -36 V, and F.E.T. 13 therefore conducts -V (-25 V) to C8. F.E.T. 9 is off because its threshold is not exceeded. During the read period # R  F.E.T. 2 conducts (F.E.T. 9 still off) and the C8 voltage is fed to line 5, reduced by the threshold drop of F.E.T. 2. The potential at C8 is also now somewhat reduced due to the voltage divider action of F.E.T.s 2 and 13, the impedance of F.E.T. 13 being made the smaller of the two, however, to minimize this reduction. The resulting stored voltage on C8 after the read period is able to restore through F.E.T. 9 any leakage from C10. If a O(OV) is stored on C10, then F.E.T. 13 is not turned on by the voltage on plate 11 even when plate 18 goes to - 25 V. The capacitor 10 may be a so-called conditionally switched capacitor as disclosed in Specification 1,254,899; or it may comprise a F.E.T. (Fig. 3, not shown) with a capacitor between source and gate, the drain forming terminal 12.

Title: Apparatus for wrapping sweets
IPC: B65B11/54
Filed: 1970-09-25
Abstract: 1334386 Sweet wrapping machines OTTO HANSEL GmbH 25 Sept 1970 [8 Nov 1969] 45752/70 Headings B8A and B8C Apparatus for wrapping sweets 18 includes two sets of folding stations a, b, c and a<SP>1</SP>, b<SP>1</SP>, c<SP>1</SP> arranged around a gripper assembly comprising two superimposed rotatable discs 7, (4, Fig. 5) provided with two series of jaws 8, 8<SP>1</SP>-11, 11<SP>1</SP> and 15, 15<SP>1</SP>-12, 12<SP>1</SP>. One disc carries the leading jaw of each pair and the other disc carries the trailing jaw of each pair, the jaws being arranged so that when one series is open the other series is closed. Each sweet 18 is brought to a feeding station A by a conveyer 16 where it receives a wrapping and is passed upwardly through a folding box or brush shoot 22 by a pair of opposed recirpocating rams 20, 21 to be brought between a pair of open jaws, i.e. jaws 8, 8<SP>1</SP> or 151, 15. The first sweet is placed between jaws 8, 8<SP>1</SP> and the discs (4), 7 are counter-rotated relatively to each other to close jaws 8, 8<SP>1</SP>-11, 11<SP>1</SP> and to open jaws 15, 15<SP>1</SP>-12, 12<SP>1</SP>. A folder 23 at station A is moved across the base of the first sweet to fold one side of the wrapping under the base of the sweet and then the whole assembly is rotated anti-clockwise one station distance to bring the first sweet and jaws 8, 8<SP>1</SP> to the folding station a and the now open jaws 15, 15<SP>1</SP> to the station A. During this rotational movement, the first sweet is swept over a folder 24 so that the remaining side of the wrapping is passed under the base of the sweet. The discs (4), 7 now rotate relative to each other to close the jaws 15, 151 about a second sweet and to open the jaws 8, 8<SP>1</SP> to allow the first sweet to be removed from the path of the jaws by a ram 27 and plate 25. The whole assembly is then rotated clockwise back one station distance so the now open jaws 8, 8<SP>1</SP>, 9, 9<SP>1</SP> and closed jaws 15, 15<SP>1</SP> return to the stations A, a and a<SP>1</SP> respectively. The ram 27 and plate 25 move upwardly to bring the first sweet between jaws 9, 9<SP>1</SP> and jaws 8, 8<SP>1</SP> receive a third sweet. The discs (4), 7 are again relatively rotated to close the jaws 8, 8<SP>1</SP>, 9, 9<SP>1</SP> which respectively grip the third sweet and fold the wrapping about the ends of the first sweet. Simultaneously the jaws 15, 151 are opened to allow the second sweet to be removed from the path of the jaws by a ram 28 and plate 26 in the same manner as for the first sweet at station a. After the next complete oscillation of the assembly each of the sweets will have been advanced by one station. In this way odd numbered sweets move anti-clockwise through the folding stations a, b, c and even numbered sweets move clockwise through the stations a<SP>1</SP>, b<SP>1</SP>, c<SP>1</SP> to an offtake conveyer 17. The sweets may be rotated through 90 degrees at the stations c, c<SP>1</SP> and may have twisted end folds. The pairs of jaws may move through 30, 45 or 60 degree spacings.
