Title: Monitoring system
IPC: A61B5/00
Filed: 1973-09-14
Abstract: 1409949 Monitoring apparatus; electro-medical apparatus D L SUSSMAN and A SUSSMAN 14 Sept 1973 43365/73 Headings G1J and G1N [Also in Division G5] In a monitoring system e.g. for the life signs of a medical patient, a collimated beam 3 of light from a source 1 is divided by beam-splitters 4a-e into various portions 5 and 5a-e, a first portion 5 passing via an optical light guide 8 comprising an optical fibre or a bundle of optical fibres without interruption to a window 12 of a display panel 11, and a second portion Se passing via optical light guides 8e, 22e to a window 12e in the panel 11, a transducer 21 for sensing a variable being monitored supplying a signal to control modulating means 18 located in a gap 15 between the aligned adjacent ends 16a, 16b of the light guides 8e, 22e respectively to impress on to the second beam portion Se a signal dependent on the variable sensed by the transducer 21. Preferably the light source 1 is a laser, such as a pulsed inert gas laser, and a lens system 23 may be used to intensify the beam. The beam-splitters 4 are semi-transparent mirrors, but if a polychromatic light source is used the splitters may operate on an intensity, wavelength, or polarization basis. The modulating means is a shutter 18 spring- loaded to a position blocking the light beam 5e, or clear of the light beam, movement of the value of the variable being monitored out of a predetermined range causing the shutter 18 to move clear of, or into a position blocking the beam, as the case may be. Preferably part of the light guide 8 is branched off at (24) to by-pass the shutter 18, continuing unbroken to a third window in the panel 11, Fig.2 (not shown). Various combinations of illumination and non-illumination of the three windows can then indicate not only the variable but also the nature of any equipment failure. In a modification, Fig.4 (not shown), a digital or analogue light modulator (27) replaces the shutter 18, the modulated beam passing to a computer (28) for store and assembly to control display equipment. In Fig.5 (not shown) the modulated beam controls an oscilloscope or oscillograph (29).

Title: Method and apparatus for induction heating of billets and for determining average temperature thereof
Inventor: ROSS NICHOLAS V
IPC: C21D1/42
Filed: 1960-12-21
Abstract: 924,691. Automatic temperature control. AJAX MAGNETHERMIC CORPORATION. Dec. 21, 1960, No. 43847/60. Class 38 (4). In order evenly to heat a metal billet to within a desired temperature range, e.g. in an induction furnace, the billet is heated in discrete stages which are automatically controlled in dependence upon the surface temperature and average temperature of the billet. As shown, curve 1 represents the average temperature of a billet being heated to a desired temperature of 1592‹ F., curve 2 represents the surface temperature, to be limited to 1675‹ F. during the heating process, curve 3 represents the temperature at the axial centre line of the billet, and curve 4 represents the position of a recording stylus (not shown) of a recording and contact making temperature responsive instrument. The billet initially heats up substantially linearly until its surface temperature reaches a point 2a on curve 2 representing the limit of 1675‹ F. This surface temperature is detected by the recording instrument which then acts to de-energize the heating circuit and to read the average temperature; if, as illustrated, the average temperature has not reached the desired 1592‹ F., the recording instrument, after a time delay, again reads the surface temperature. Assuming this to have fallen to a point 2b, below a lower control-point 1665‹ F., power is again turned on and the surface temperature rises from point 2b to point 2c-again at the upper limit of 1675‹ F. Power is again removed automatically, and the recording instrument is transferred to read average temperature. Assuming again that the average desired temperature has not been reached, the recording instrument returns to read surface temperature. If, as shown, this surface temperature is above the lower control value of 1665‹ F., power is only reapplied when the surface has cooled to the point 2d, representing 1665‹ F. The surface temperature then rises from point 2d to point 2e and power is removed. The recording instrument then reads the average temperature, now assumed to be above a low average control value of 1582‹ F.; after a fixed time period the recording instrument is transferred to read surface temperature, and cycles the heating periods to maintain the surface temperature and the average temperature between 1582 ‹ and 1592‹ F. An electrical circuit for effecting the method is described (Fig. 2, not shown), in which three thermocouples are used to measure the surface and average temperatures, and in which the recording instrument has contacts operating relay coils to control the heating cycle. Specifications 742,856 and 835,825 are referred to.

Abstract: 967,631. Transistor pulse circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 16, 1961 [Dec. 24, 1959], No. 43894/59. Heading H3T. Fig. 1 shows a circuit similar to that described in Specification 965,546, but using transistors of opposite conductivity types. The blocking oscillator comprising PNP transistor T1 and transformer TR provides a pulse shown in Fig. 2a when a pulse at Y is coincident with a clock pulse at X. The positive part of the pulse is passed by diode M1 and renders the symmetrical NPN transistor T2 conductive so that the collector voltage falls from the value set by diode M3 approximately to the emitter voltage. T2 remains conductive due to storage of minority carriers (Fig. 2b) until the output pulse at terminal OP is terminated by a reset pulse at Z. The output pulse may be fed back to the input to provide a one-digit store. More than two input lines may be used by the addition of further diodes or the provision of both AND and OR gates.

Abstract: 1440646 Automatic control INTERNATIONAL BUSINESS MACHINES CORP 1 Oct 1973 [11 Oct 1972] 45754/73 Heading G3N [Also in Division H2] A feedback control system for a stepping motor in which speed dependent pulses from a pulse emitter coupled to the motor shaft control the supply of motor advance pulses includes motor speed-changing means operable when a predetermined number of steps before the end of a specified movement has been reached to slow the motor from a high speed range by masking two successive feedback pulses, and speed holding means subsequently operable to apply an additional motor advance pulse to the motor and thereby hold the motor at a desired low speed. The motor is preferably used in a print-head driving arrangementt and in a particular embodiment, 5 steps of the motor are equivalent to one printing space. The speed-changing means preferably includes a spacecounter which is pre-set to the number of spaces to be moved in a high-speed range, and a motor stepping counter fed with a start and feedback pulses which counter is operable to decrement the count in the space-counter, a latch circuit being set when the count in the latter reaches zero to feed a signal to an AND gate which is enabled by the next occurrence of a predetermined step of the motor to set a further latch to generate a motor advance pulse extending until the latch is reset by the next but one feedback pulse, thereby generating a single pulse which is equivalent in length to three feedback pulses. The rotor field will be thereby considerably advanced to slow the rotor and just prior to a selected low speed an additional advance pulse is generated, which generation is controlled by a delay and a further latch circuit so that the pulse is emitted when the repetition period of the feedback pulses is longer than a predetermined time. A further pre-set counter is enabled to be decremented by the step counter after the space-counter has reached zero and control means, comprising a set of variable or fixed duration and monostables, to slow the motor to a standstill is provided which is activated when the count in this further counter is 1. This control means generates a first motor advance pulse directly from a feedback pulse and subsequent pulses coincident with the trailing edges of single pulses from the variable monostables whose time of initiation is controlled by the feedback pulses and whose duration is individually adjustable.
