[Also in Division G1] Electromechanical device indicating the relative displacement of a diffraction grating and a crossed index grating with a precision of a small fraction of the width of one of the fringes produced, in which the gratings and associated reading means are arranged to produce two signals proportional to sine and cosine of the fraction of a fringe to be determined, which are passed through respective coils at right angles one to the other to produce crossed magnetic fields proportional thereto, whose resultant field has an angle to the cosine field proportional to the variable; means being provided to determine the direction of the resultant field. In relative displacement measurement, a diffraction grating 10 is movable relatively to an index grating 12 (Fig. 1) of four sections 14, 15, 16, 17 with the lines of the second, third and fourth section displaced 90 degrees in phase with regard to its predecessor. The gratings are illuminated and the sections are read by respective photo-cells 18, 19, 20, 21 connected out of phase in pairs 18, 20 and 19, 21 to produce outputs proportional to sin # and cos #, where # is the fraction of a fringe width to be determined. The outputs energize coils 22, 24 at right angles and the resultant field makes angle # with the cosine field indicated by screened magnetic needle 26. Alternatively the output signals energize through slip rings 56, 57, 58 two right-angled coils 50, 52 rotatable about a common axis in the uniform field of permanent magnet poles 54, 55 without torsional restraint, to assume an angular position such that the resultant field is aligned with the magnetic axis and pointer 60 indicates #(Fig. 2).

Abstract: 1478258 Tenderizing meat by electrical treatment NEW ZEALAND INVENTIONS DEVELOPMENT AUTHORITY 17 July 1975 [18 July 1974] 30075/75 Headings A2D and A2U Meat carcasses are conditioned before freezing thereby preventing both cold and thaw shortening and tenderizing the meat by (a) suspending a freshly slaughtered carcass with an electrical contact 23 at or adjacent the point of suspension; (b) advancing the carcass to contact an electrode 14 remote from the point of suspension and (c) electrically stimulating the carcass by applying a pulsating potential difference between the contact and the electrode to stimulate glycolytic reaction in the muscle of the carcass. In the embodiment shown the sheep carcass is treated whilst it is conveyed along overhead track 11. Clamp 23 which also serves as an electrical contact comprises a fixed bar 24 and a series of clamping bars 25 spring biassed towards it (Fig. 6-not shown). Electrode 14 comprises a series of plates 21 mounted to brush against the carcass (Fig. 5-not shown). Insulated boards 22 help to orientate the carcass and in order to assist in making a satisfactory contact the edge of electrodes 21 is wetted with water from line 20.

Title: Electronic service request system
IPC: G06F13/364
Filed: 1968-06-25
Abstract: 1,217,355. Priority circuits. INTERNATIONAL BUSINESS MACHINES CORP. 25 June, 1968 [7 July, 1967], No. 30175/68. Heading G4A. An electronic service request system includes a register arranged to register and indicate the registration of request signals, inhibiting means responsive to the registration of a request signal to prevent the registration of further request signals, the inhibiting means taking a fixed time interval after the detection of the request signal to take effect, and means for indicating the registration of only one of the requests, including the request to which the inhibiting means was responsive, registered during the fixed time interval, this indicated one of the requests being the request of a given priority in a predetermined scale of priorities. Priority circuit.-Storage access requests from channel units and processors at 30, 31, 32, respectively, set respective latches 40, 42, 44, provided storage is not busy as indicated by a line 35 being de-energized. The first latch to be set prevents the setting of any others after a time interval defined by circuit delays, using inverter 37 &c. An output is produced at 46, 66 or 68 according to the highest priority (uppermost) latch set due to inhibition of lower priority channels by higher priority channels using inverters 59, 63. This output is used to grant access when an output is produced at 58 from AND 50, this being in response to an output at any of 46, 66, 68 but being delayed as necessary to ensure that the highest priority request in the whole time interval is granted even if a lower priority request occurs earlier in the interval. This delay is achieved by inhibiting AND 50 through an inverter 57 for as long as there is any channel with a set latch which has not been inhibited (at 60, 64) by a higher priority channel with a set latch and in which the beginning of the set state of the latch, inverted at 52, 69, 72, has not yet emerged from a respective delay 54, 70, 74 to inhibit an AND 55, 60, 64. When a request is granted, the corresponding latch is reset. In effect, the circuit does not wait, on receiving a request of the highest possible priority viz. at 30, to see if any higher priority requests occur in the rest of the time interval but does wait if the first request (which initiates the time interval) is not of the highest possible priority. It is mentioned that the invention may be incorporated in the priority circuit of Specification 1,217,354 in the tie breaking part.

[Class 69 (i).] In a liquid-meter having two measuring chambers, the inlet and outlet valves 14, 24, Fig. 2, of each chamber are operated from a shaft 21, the oscillations of which are effected from a diaphragm 32, Fig. 1, forming one wal of a chamber which communicates with the supply conduit 12 under the control of a valve 33. The valve 33 is closed by its spring 34, and opened by an arm 39 by the fall of a float 36 in the outlet chamber 63. The excess pressure due to the filling of a' chamber moves the diaphragm and causes a tongue 44 to engage one face of a tooth 46 of a disc 47 loose on the shaft 21 and held by engagement of a projection 59 with a stop 60. The tongue then engages and drives a disc 48 fast on the shaft, the stroke being completed by a spring throwover device 51, 54, and the disc 48 acting through screws 49 and slots 50 to turn the disc 47 until its projection 59 engages a stop 601 and the other face of the tooth 46 is presented to the tongue 44.
