The carriage 15 slides on both rods 11, 12 with a limb straddled by two limbs of the pen holder 16, one limb of which holds a screw 17 for adjusting the degree of lost motion. A magnet 20 carried by the carriage 15 co-operates with an endless, ferro-magnetic chain 21 on sprockets, one of which is driven by a motor 27 in a bridge circuit. The circuit includes a wiper 23 on the carriage dividing a resistance 22 to form two arms, the other two 24, 25 being formed by a constant resistance and by one representing the variable to be recorded. The outputs 28 of the bridge are applied to an electrolic amplifier 29 connected to a relay 32. The relay 32 is adapted to connect a source of current to the motor 27 with the appropriate polarity to remove unbalance. The lost motion mechanism avoids recording oscillations due to hunting and the magnetic "clutch" 20, 21 allows slipping due to any obstruction of the carriage and so prevents damage. The holder 16 has a spring clip to grip a pen 19 and the holder 16 is pivotable about the rod 12.

Abstract: 1336626 Processing semi-conductor wafers; electron beam apparatus MULLARD Ltd 13 Dec 1971 57769/71 Headings H1K and H1D [Also in Division G3R] In a manufacture involving the use of an electron beam, the semi-conductor wafer under process is provided with one or more alignment structures 3-6 for use during successive exposures of the wafers to the electron beam. Each alignment structure consists of two regions, a, b (preferably of identical size and shape) of one conductivity type separated by an intermediate region 7 of the opposite conductivity type. The intermediate region may be part of the bulk wafer and the two regions may be formed during a first diffusion stage. In the embodiment, several stages involve the selective exposure of a coating of electron resist on the wafer. The mask used for a given exposure is a chromium optical mask which allows U.V. radiation to reach only selective areas of a caesium iodide photo cathode. Each mask has narrow alignment apertures, each of which results in the formation of a narrow electron beam which falls on part of the appropriate intermediate region. A difference amplifier connected between contacts on the two regions gives an output dependent on the direction and distance of the beam from the centre line of the intermediate region. Focusing and/or alignment coils are driven in response to the signals from the alignment structures to redirect the beam until the correct orientation is achieved. The exposed and treated electron resist may be used as a mask for the selective removal of insulating or metallic layers from the wafer.

Title: Subscriber carrier telephone system
IPC: H04Q11/02
Filed: 1971-04-22
Abstract: 1348141 Party line systems STANDARD TELEPHONES & CABLES Ltd 22 April 1971 10691/71 Heading H4K A subscriber carrier telephone system includes a switch at the subscriber station operable to cause an "out-of-band" signal to be transmitted and when detected in the exchange. carrier equipment causes a required condition to be set up. The switch may be used to provide a recall or call transfer facility. In the system described the exchange equipment transmits speech signals on a second carrier frequency of 64 KHz with ringing signals provided as bursts of carrier interrupted at 17 Hz by the operation of signal detector ESD. These signals are detected in the subscriber unit and the bursts of carrier operate a 25 Hz ringer. When the subscriber station telephone instrument SCT is off hook a control circuit SCC starts oscillator SCO to transmit a first carrier frequency of 28 KHz to the exchange. This carrier is detected and causes relay A1 to operate to loop the line DEL. Dial pulses are sent by interrupting this first carrier frequency to cause relay A1 to act as impulsing relay. Speech may be transmitted by amplitude (circuit of Fig. 1) or frequency (circuit of Fig. 4) modulation of the respective carriers. Operation of switch contacts RC causes 7 KHz oscillator SRO to start and either to modulate the existing first carrier or to replace it to provide the out of band signal. In the exchange the signal is detected in detector ED2 and operates relay B 1 to earth the line RL through contacts b1. In a modification a single oscillator may be used in the subscriber station and closure of switch contacts RC causes a transistor to conduct to short circuit a resistor in the oscillator circuit thus causing a different frequency to be transmitted, Fig. 2 (not shown). In a further modification the detector in the exchange unit may be replaced by a logic circuit, including a monostable circuit, where the output level of the logic circuit changes if the received frequency changes from greater than to less than half the period of the monostable circuit, Fig. 3 (not shown). Both the exchange and subscriber stations are provided with AGC loops which change the transmission level to compensate for the length of line.
