Abstract: 1,259,787. Measuring displacement electrically NATIONAL RESEARCH DEVELOPMENT CORP. Oct.8, 1969 [Nov.26, 1968J, No.55949/68. Heading G1Nx. [Also in Division G3] Three flat zig-zag windings 2, Fig.2, are symmetrically interleaved and connected to a 3-phase A.C. supply R, Y, B to produce a linearly developed 3-phase magnetic field which is sensed by a pick-up coil 1. The phase of the voltage signal in coil 1 is determined at 5 by reference to the voltage between the RY phases and is indicative of the position of coil 1 within one pitch of six conductors of the 3-phase winding 2. The particular pitch is determined by counting zero phase positions as coil 1 is moved from one end of winding 2, or a further single pitch 3-phase winding 10, spread over the total range of movement at an angle and having its own pick-up coil 9, enables the pitch position to be determined. The position signals may be compared with signals from a demand device 12, representing a desired position, any difference causing a motor 11 to move coils 1, 9 until the difference is eliminated. The 3-phase winding 21 may be circular in form, Fig.4 (not shown) to measure angular displacement. The 3-phase winding 26, Fig. 3 may be preformed to a shape to be followed by a work tool on a slide 25, attached to the pick-up coil 20. The slide is traversed longitudinally in the direction 22, and the phase of the pick-up signal is compared at 21 with a desired phase, any difference being fed to a motor 23 to move the slide transversely in the direction 24. Alternatively Fig. 5 (not shown), the pick-up coil 41 is traversed longitudinally and the phase of the pick-up signal compared at 42 with that in the rotor of selsyn 46, any difference being fed to a motor 44 to rotate the rotor and a tool attached to shaft 47 until balance is restored.

Abstract: 1334287 Oscillator circuit ITT INDUSTRIES Inc 2 Dec 1971 [5 Dec 1970] 55961/71 Heading H3T An oscillator comprises two like-conductivity, emitter-coupled transistors T1, T2 the collector of transistor T2 being connected to the base of transistor T via a series resonating circuit, the bases of transistors T2, T1 being direct current connected to the collector supply line directly and via an impedance respectively. The series resonant circuit may comprise a quartz crystal Q and a trimming capacitor C. The output signal u may be taken from the collector of transistor T2 or T1 if transistor T1 is provided with a load impedance. Each load impedance may be a parallel tuned circuit. For harmonic oscillation a parallel tuned circuit mf (Fig. 2, not shown) is used for a collector load of transistor T1 and for overtone working as the collector load of transistor T2 (Fig. 3, not shown) or the base impedance of transistor T1 (Fig. 4, not shown). Harmonics of the overtone frequency may be obtained by appropriately tuned parallel resonant collector loads (Fig. 5, not shown). A coupling coil may be used around either resonant circuit for providing an output signal. In integrated form, each resistor R1, R2 and the collector load of transistor T1 may be a transistor, constant current source. The output signal voltage is limited to the difference between the base emitter potential of transistor T2 and the saturation voltage of transistor T, if the output is taken from one of the collectors.

Abstract: 1,269,300. Data processing. INTERNATIONAL BUSINESS MACHINES CORP. 8 Dec., 1970 [10 Dec., 1969], No. 58261/70. Heading G4A. In a data processing system, a data processing device performs tasks specified by task words transferred to it from a programme scheduling device which stores task words and transfers them to the processing device in an order determined by their service ratios, the service ratio of a task word being directly proportional to the time needed to complete the task and inversely proportional to the time remaining before the task must be completed. A task word consists of an address (pointing to the task status word which includes the first instruction of the task programme), and the two times (see above) from which the service ratio is calculated. The task words in the scheduler are each stored in a "table" respective to the range in which its service ratio lies, each "table" having associated with it a respective series of boundary counters specifying groups of task words in the "table" in the order of how long the tasks have not received service. The task words in the "tables" are updated periodically and the service ratios recalculated, at a frequency which is higher, the higher the range of service ratios respective to the "table", task words being transferred between "tables" as appropriate to the new service ratios. Task words are selected from the "tables" for allocation to respective processors, the higher the range of service ratios of a "table" the more frequently that "table" is chosen, task words being chosen from a given "table" on the basis of oldest first. When a task word is allocated to a processor, this is an idle processor or one chosen on the basis of having a current task with the smallest service ratio. In the latter case, the processor is interrupted and its current task word is supplied back to the scheduler for storage in one of the "tables". A processor cannot be interrupted as above more than once in a predetermined time slot. A processor may execute multiple instructions simultaneously.

A photographic type-composing machine comprises a rotary member 21, Fig. 8, carrying a plurality of type characters 25, a selectively operable source of illumination 24, a plurality of objectives 22 with parallel optical axes focused on the surface of member 21, and a camera lens 23 arranged to focus all the parallel light fluxes emerging from objectives 22 on photo-sensitive material 27. Character-carrier.-A preferred form of character carrier is a rotary drum having an array of windows in its cylindrical wall, one or more character boards being removably mounted on the inside surface of the drum in register with the windows. Therefore, changes in type style can be accomplished by changing the boards instead of replacing the entire drum. Fig. 6 illustrates a drum 1 having a window 3 behind which is removably mounted a character board in the form of a negative film 5; the film is mounted with a slight air gap between it and the window surrounds but centrifugal force presses the film uniformly against the inside drum surface. Film holders 8 made of magnetic material, and attached to film 5 by pins 9 are attracted to magnets 11 fixed in the drum 1. When it is required to remove a film 5 from the drum 1, a housing member 14 is introduced into the drum and magnet plates 15 on the sides of the member 14 are attracted to the film holders 8; the housing member 14 is then pulled away, using base 18, and the greater magnetic interaction between plates 15 and holders 8 overcomes the interaction between holders 8 and magnets 11. When a new film is to be introduced, the film holders 8 and film 5 are placed on member 14 and introduced at the required position; plates 15 are disconnected from holders 9 using pins 16, and pins 17 then push the holders 8 towards magnets 11. Optical system arrangements.-The objective lenses can be positioned in various arrays with respect to the rotary drums, Fig. 10 (not shown). More than one rotary drum 21 can be used, with axes parallel or at right angles to each other. In these cases, there are reflector(s) positioned either between the drum(s) and the set(s) of objectives or between set(s) of objectives and the camera lens, Figs. 11 to 15 (not shown). There may be one or more sets of objectives, the sets being parallel or at right angles to each other.
