Abstract: 1301579 Velocity measurement; DC level correction in amplifiers F HOFFMANN-LA ROCHE & CO AG 13 May 1970 [5 June 1969] 23296/70 Headings H3T and H4D A method and apparatus of producing a signal representative of the velocity of a moving surface provides the steps of (a) transmitting an energy wave at the surface (b) detecting the FM and AM components of the combined unmodulated and Doppler shifted received signals (c) analogue division of the FM component by the Am component. Crystal 13 energized by oscillator 12 radiates a CW fixed frequency ultrasonic signal on to a moving surface, e.g. fluid flow in the human body. Signals reflected from the moving surface combine with unmodulated reflection in the receiving crystal 23 producing a frequency and amplitude modulated signal. Due to the nature of the signal the FM component may be detected by synchronous amplitude demodulation using the transmitted signal shifted by 90 degrees, followed by differentiation. The FM signal is fed to the numerator input of a divider 41. The AM component is detected in demodulator 28 and passes through a baseline setting circuit 29 which sets the zero mid-way between the signal peaks. Circuit 29 inhibits the passage of the signal if the amplitude is within a preset band around zero. It also reverses the polarity of any negative signals since the divider 41 cannot accept negative denominators. After division the correct polarity is re-established for the relevant portions of the signal which is then passed through a low-pass filter to remove the discontinuities caused by the zero inhibit circuit. The output from the filter is representative of the instaneous velocity of the surface and that of integrator 51 represents the displacement of the surface. Other forms of energy (e.g. radar) may be used. D.C. level correction (Fig. 3).-Circuit 29 comprises a differential amplifier 54 having one input grounded and the other connected to the AM detector. A feedback path 70 has two portions one of which integrates positive output peaks which are passed by diode 69 and the other operates through diode 71 on negative peaks. The resultants are arranged to subtract and are fed back to the input to adjust the D.C. level of the input, and thus of the output.

Abstract: 1311178 Making semi-conductor devices FERRANTI Ltd 16 Sept 1971 [19 Sept 1970] 44725/70 Heading H1K The figure shows a part-way stage in the manufacture of a read-only memory store and depicts one isolated pocket 55 of a 3 x 3 diode matrix only selected diodes of which are to be connected between the input and output lines. The three regions 58 form PN-junctions 11 with the epitaxial layer 55 to form three diodes associated with input line 20. This line contacts the layer 55 via an enhanced conductivity region 57. In forming the matrix the selected diodes are connected to output lines 30, 31, or 32 by applying a voltage pulse between the line and region across the reduced thickness portion 62 of the passivation to establish a permanent ohmic contact. The pulse is of greater magnitude than any pulse used in operation of the store, but is not so large as to damage the junction. In the example, the body is of silicon, the passivation 60 is of silicon oxide, and the contact material is aluminium or " Nichrome" (Registered Trade Mark). The method of connecting selected cells may be applied also to transistors or multi-component bi-stable elements.

As shown, the bath has two narrow slots 2 formed in one vertical wall 3, the slots beginning at the upper edge and terminating towards the bottom of the bath in an enlargement 4 of the slot. On the wall 5 of the bath 1 opposite wall 3 are attached two blocks 6 carrying snubbing pin 7, preferably in a demountable manner, a short distance above the upper edge of wall 5. Treatment liquid heated to a suitable temperature is supplied to the bath through a pipe 8 at the bottom and overflows at the upper edge of wall 5 which is preferably slightly lower than the upper edges of the other bath walls. Another yarn guide 9, which is preferably a smooth ceramic guide or may be a snubbing pin is arranged above the pin 7 and to one side, so as to cause a sharp change in direction of movement of yarn 10 at pin 7. Guide 9 is preferably arranged so that yarn passing thereover suffers an additional change of direction before passing onwards. In Fig. 2 a bath 1 having only a single slot 2 is enclosed in an outer container 11 to confine any splashed bath contents as much as possible and the whole apparatus is mounted on a drawframe comprising a feed roll 12 with idler roll 13, draw rolls 14 in a heated enclosure 15 and additional take-up rolls 16. Examples illustrate the drawing of polyamide and polyester yarns.

Abstract: 1326731 Current collection in homopolar dynamo-electric machines INTERNATIONAL RESEARCH & DEVELOPMENT CO Ltd 24 Aug 1970 [27 Aug 1969] 42638/69 Heading H2A In a homopolar dynamo-electric machine liquid metal is supplied to a region of the rotor radially inwards of its periphery, so that under the action of centrifugal force the liquid metal is thrown radially outwards through openings at the rotor periphery on to a stationary current collecting surface. In Fig. 4 the rotor is formed from two discs 20, 21 having a cavity between them, and the liquid metal, supplied via the hollow shaft 12, is thrown radially outwards through a circumferential slit 22 to impinge upon a current collecting surface 19 of an annular trough 18. The liquid metal which collects in trough 18 is recirculated to the hollow shaft 12 via a screw pump (30, 31, Fig. 6, not shown) on the shaft, the recirculating path being interrupted, e.g. by a mesh which breaks up the liquid into droplets, to avoid short-circuiting the rotor. In a modification, the liquid metal flows through radial tubes in the rotor. In Fig. 7 an annular trough 34 mounted on the rotor periphery 33 is supplied with liquid metal from stationary pipes 36, the liquid metal flowing radially outwards through openings 37 in the trough 34 to impinge on a surface 38. It is said that the rotor may be made of insulating material so that the liquid metal itself constitutes the rotor conductors.

Abstract: 1353368 Automatic exchange equipment INTERNATIONAL STANDARD ELECTRIC CORP 8 Sept 1971 41831/71 Heading H4K In a PABX attempts to make trunk calls are investigated and if unauthorized the call is barred. A logic circuit contains circuitry for responding to the dialling signals to provide encoded signals corresponding to at least one digit which encoded signals are stored and decoded to determine whether they represent a demand for an unauthorized call in which case signals restricting the completion of the call are provided. In the arrangement shown a subscriber L/C on lifting his handset will gain connection through the PNPN diode matrix M1 to a local junctor 6 and register 8. If the subscriber now dials an access code for an exchange line, junctor 6 and register 8 will be disconnected and a connection made through matrix M1 to the trunk circuit 14 which has an exchange line connection at 16. A connection is also made to the restrictor circuit 20 and the trunk allotter circuit 22. The subscribers are also connected to a class of service wiring field 32 containing diodes which are connected to the circuit 36 so that for a subscriber who has an unrestricted dialling facility the restrictor circuit 20 is not used.

The pulses are counted and are stored in sequence in hundreds, tens and units stores which sequence is controlled by an interdigital timer. The stores each comprise four toggles to control 10 gates giving a decimal output which is connected through wired programming to a NAND gate whose output supplies a signal on line 18 to indicate the authorization status of the call.
