Patent GB-1370163-A (GB)
Title: Telephone systems
IPC: H04M19/02
Filed: 1972-03-08
Abstract: 1370163 Automatic exchange equipment SIEMENS AG 8 March 1972 [11 March 1971] 10695/72 Heading H4K Different tones, e.g. ringing tone, dialling tone, busy tone, and break-in tone, supplied via a transformer to a transmission path, are generated by interrupting the supply of a constant frequency signal to a winding of the transformer using a D.C. controlled switch, the tones being distinguished by different interruption rates. The system is also arranged such that a purely A.C. signal is generated in the transformer winding. A plurality of connecting sets VS 1 to VSx are connected to an electronic crosspoint switching matrix (Fig. 1, not shown), and include windings 1 of respective tone coupling transformers D1 to Dx, second windings 2 of these transformers being coupled via tone signal switches S 1 to Sx to a constant frequency tone generator HQ. Transistors T13 to Tx3 control the tone signal switches in dependence on a potential applied to their bases by respective sets of logic circuitry AW 1  to AW x , which each have first inputs from a set of bi-stable elements AUx, FRx, BSx, Wx, Xx whose states are governed by the condition of the subscribers line the status of the call viz. whether the connection requires the application of ringing tone, busy tone, &c. and second inputs from a number of pulse sources Si to Six, common to all sets of logic circuitry, and each having a frequency corresponding to the interruption rate required for a respective one of the tones. In operation transistors T13 to Tx3 are normally held off by the output of a respective negation gate N1. If, for example, a called subscriber's line circuit is free, bi-stable FR1 is set, and a gate GF1 will be alternately enabled and inhibited by the pulses on line Si2. This causes the output from negation gate N1 to alternately enable and disable transistor T13 at the same rate. When transistor T13 is off, transistors T11 and T12 in the "tone signaswitch" are held off and tone signal from general tor HQ does not reach transformer winding 11 of D1. However, when transistor T13 is on, on positive half cycles of generator HQ a current path is established via transistor T12, diode D11, resistor Rv1 and the winding 2. On negative half cycles the path is established via transistor T11, diode D12, resistor Rv1 and the winding 2. Hence a purely A.C. signal is applied to winding 11 which is interrupted at the rate at which transistor T13 is enabled and disabled. Other tones can be likewise applied. The resistance of Rv1 in conjunction with the internal resistance of the generator HG determines the attenuation factor governing cross-talk during the application of tone signal, and this resistance can be adjusted for each connecting set.

Title: Double-oriented single crystal castings
IPC: B22D27/04
Filed: 1970-03-10
Abstract: 1280055 Crystal growing UNITED AIRCRAFT CORP 10 March 1970 [13 March 1969] 11326/70 Heading B1S [Also in Division B3] Single-crystal doubly-orientated alloy castings are manufactured in an apparatus including a shell mould 10 having an article-forming cavity 12, a constriction 16 at the base of the article-forming cavity and a crystallization starter portion communicating with the constriction 16. The starter portion comprises a vertical passage 20 and a horizontal passage 18, each passage being closed at its lower end by a water-cooled chill plate 24. The lengths of the two passages from their junction to their chill plates differ. The shell mould is surrounded by heaters and backed up by a refractory packing 28 in a flask 26. Before casting the shell mould is heated to above the melting point of alloy and the alloy with at least 100‹F superheat is cast into the mould. Solidification starts at each chill plate, and at the junction of the passages 18 and 20 the columnar dendritic growth from each chill plate meets so that the dendritic growth is oriented in two perpendicular planes. As the vertical axis of the cast body is to be the stress axis of the body the passage 20 is shorter than passage 18 and the vertical orientation of the dendritic growth is stronger than its horizontal orientation. If the body requires a horizontal stress axis then the passage 18 is made shorter than passage 20 (Fig 2 -not shown). The constriction 16a, 16b, 16c, selects one of the grains from the starter portion as solidification is effected upwardly into the article forming mould portion 10.

Abstract: 1,173,911. Semi-conductor devices. PLESSEY CO. Ltd. 14 Feb., 1967 [15 March, 1966], No. 11397/66. Heading H1K. A structure comprising an insulating substrate, e.g. of α-alumina or quartz, having a plurality of recesses each filled with single crystal semi-conductor material is made by a method comprising forming the recesses in the substrate, overfilling them with semiconductor and then removing the excess semiconductor. The separate semi-conductor bodies thus formed may be interconnected-e.g. by low resistivity semi-conductor deposited in channels linking the recesses-to form an integrated circuit. The recesses are formed by masked etching of the substrate, and semi-conductor material is deposited epitaxially (e.g. from doped silane) all over the recessed surface. The surface is then cleaned mechanically and/or chemically to leave isolated semi-conductor bodies in the recesses. Before such cleaning, the surface may be masked and etched to provide a second set of recesses extending through the already present semi-conductor and into the substrate in locations apart from the original recesses. A second deposition, of opposite conductivity type semiconductor, is then performed. After surface cleaning in this modified process, the substrate contains two sets of recesses-one set containing P and the other N type semi-conductor. Interconnecting semi-conductor in channels linking the recesses may be provided by a like etching, deposition and cleaning process.

Abstract: 1,249,582. Boring earth and rock. BYRON JACKSON Inc. 5 March, 1969 [6 May, 1968], No. 11830/69. Heading E1F. In the drilling of curved boreholes, an instrument I carried within 'the drill string signals an indication of the angle of torsional twist of the drill string by generating a number of pulses in the drilling fluid. The instrument comprises a body 30, 37 fixed within a drill collar sub D below which is an angled sub, a mud driven motor and a bit. The body contains an eccentrically weighted member 130 rotatably mounted on a housing 111 and provided with clutch teeth 133 engageable with projections 132 on a clutch sleeve 131 rotatably fixed relative to the body. The housing is non-rotatable relative to the body and is mounted on a slidable assembly comprising rod and tube members 60, 74, 117. The rod 60 slides in a fixed tube 61 having stop means, e.g. axially spaced sets of balls such as 75a, which are cammed outwardly by thimbles such as 72a to engage an inwardly extending ledge (not shown) in a sleeve 13 connected to a pulse producing member 14 to limit the upward travel according to an inverse function of the upward displacement of the rod 60. The member 14 is biassed upwardly by a spring 15 and is held on its seat 31 by drilling fluid pressure. When the drilling fluid pressure is reduced fractionally the member 14 rises releasing the members 60, 74, 117 which are displaced upwardly to lift the clutch sleeve 131 which locks the eccentrically weighted member 130 against further rotation. The drilling fluid is then cut off and the members 60, 74, 117 rise further lifting the housing 111 until a projection 135 on the member 130 abuts one of a series of steps 200 on a stop member 100. The member 14 rises until the ledge in the sleeve 13 abuts the first set of outwardly cammed balls. The drilling fluid is then restarted and the member 14 is returned to its seat, passing constrictions 7 (only two of which are shown) to produce a number of pulses. The rotation of the eccentrically weighted member is damped by fluid between closely concentrically spaced surfaces (152), (153) Fig. 4 (not shown). The upper surface of the projection 135 may be rounded. The stop member (100), Figs. 6, 7, 8 (not shown) may have various arrangements of steps 200, (200a- 200f) subtending different angles. The instrument may be used with a directional drilling bit.
