Title: Method and apparatus for processing organic food substances by the  passage of electric current
IPC: A23L5/10
Filed: 1971-08-23
Abstract: 1367612 Processing organic foodstuff ELECTRO-FOOD A B 23 Aug 1971 [24 Aug 1970] 39442/71 Heading A4D [Also in Division A2] An organic food substance, particularly potatoes, is processed by passing alternating electric current between electrodes in an electrolyte bath in which the substance is immersed, the power supplied during the processing period through the electrodes not being maintained at a constant level, changes being made in the electrical supply such that the total energy consumed in the processing period is less than if the power at the beginning of the period was maintained constant throughout the period. In apparatus for boiling potatoes a plurality of vessels 3, Fig.1, on a conveyer 1 pass under a feed position 9 where potatoes and electrolyte (water) are introduced into each vessel which has internal electrodes connected to external brushes 27 on the inner side of the conveyor. Along and under the top run of the conveyer are four parallel contact rails each divided into three sections A, B, C and connected to neutral and the three phases of an A.C. supply, each vessel being connected between neutral and one of the phases in a manner which distributes the load between the three phases and so that the potentials applied to each vessel along sections A, B, C are, for example, 220, 160 and 75 V r. m. s. respectively. The processed potatoes and electrolyte in the vessels are discharged into a receptacle 13. Along section A only the center portions of the potatoes are heated, the water being heated up gradually, whilst along section B the water is heated to 100‹C. and the whole potato heated and along section C the water remains at or just below boiling point and the outer potato layers are given final preparation. Alternative apparatus comprises a vessel 31, Fig.3, containing electrolyte and seven elongated metal strips E1-7 of which E1, 3, 5 and 7 are connected to neutral and E2, 4, 6 are each divided into four electrode sections, such as R1-R4, and connected via relays K1-K4 respectively to a respective one of the three phases of an A.C. supply. Potatoes 33 are fed in the direction of arrow P between the strips E1- 7, the coils of the relays being energized via a programming device so that only two electrode  sections for each phase are energized at any one time. The programming device interrupts the connection to each of the sections of strips E2, 4, 6 at a variable rate between 1 and 20, but preferably equal to 10, times per minute. Voltage regulating apparatus may be connected between the A. C. supply and the electrode sections allowing variation of the power supplied, as compared to constant power processing, by voltage changes as well as by intermittent current supply.

Abstract: 1386063 Automatic reversing gear HONEYWELL INFORMATION SYSTEMS ITALIA SpA 30 Aug 1973 [1 Sept 1972] 40983/73 Heading F2D [Also in Division B6] An automatically reversible drive mechanism using toothed or friction wheels and suitable for winding an inking ribbon in a printing machine &c. comprises a driving wheel continuously driven in one direction, a planetary wheel engaged with the driving wheel and alternately engageable with either of a pair of driven wheels, and resilient mounting means for the driving and/or the driven wheels whereby, in response to increase of torque transmitted to a driven wheel, the planetary wheel is enabled to pass between that wheel and the driving wheel to transfer the drive to the other driven wheel. As shown, a spur wheel 17 mounted on a resilient arm 15 is continuously driven in the direction F1 by a motor M and meshes with a planetary wheel 18 engaging a wheel 5 to transfer ribbon from a spool 13 to a spool 12. When the spool 12 is arrested by completion of the transfer, the planetary wheel passes between the wheels 17, 5 and is then carried by friction to the position 18<11> where it engages a wheel 7 in mesh with a wheel 6 to rewind the ribbon on to the spool 13, and when the rewinding is completed the planetary wheel passes between the wheels 17, 7 and is carried round to re-engage the wheel 5. The wheel 7 for reversing the direction of rotation of the spool 13 may be dispensed with if the ribbon is arranged to be wound on to either spool by rotation in the same direction. The equal reversing times due to the different lengths of arc traversed by the planetary wheel in moving between the driven wheels may be eliminated by providing several planetary wheels, or by locating the shaft 16 between the axes of the driven wheels and modifying its resilient mounting to permit movement along a line joining those axes. Fig. 3 shows an arrangement in which either of a pair of face or crown wheels 20, 21 biased by springs 26, 27 on coaxial shafts 22, 23 is driven by the driving and planetary wheels 24, 25. Instead of, or in addition to, the springs 26, 27 the driving wheel may be resiliently mounted for movement in the directions F6, F7. A reversing drive for a single shaft may be provided by keying the two wheels 20, 21 to a common shaft. As shown in Fig. 4 two intermeshed wheels 33, 34 are alternately engaged by the planetary wheel 31 so that an output shaft 35 is driven in either direction.

As shown in Figs. 1, 2 the lower portions of the tapes 11, 12 are devoid of fasteners 13 so that stitching 18 securing the fastener to a garment 19 can pass from one tape to another between one of the gaps 17. Alternatively, Fig. 5 not shown, the stop members (16) are applied over some of the coupled fastener elements (13) at the bottom of the fastener. The stop members 16, which are formed e.g. of plastics or wire filament may be e.g. of semi-circular or triangular section and should preferably have a rounded periphery to slidingly guide a mis-aligned needle. The bottom stop members 16 can advantageously be fitted to flexed areas of tapes such as boots, bags, &c. Figs. 3, 4 not shown.

Title: Determining distance-to-fault in electrical systems
Inventor: HOEL HANS
IPC: H02H3/40
Filed: 1967-09-08
Abstract: 1,204,901. Locating faults. ENGLISH ELECTRIC CO. Ltd. Sept.8, 1967 [Sept.13, 1966], No.41246/67. Heading G1U. To determine the distance between a monitoring station and a fault in an A.C. power transmission system, the value of the ratio of the system voltage and the rate of change of current at the monitoring station is determined and indicated at the instants at which the current traverses its zero. This ratio measures the inductance of the system between the monitoring station and the fault, this inductance being directly related to the required distance. The apparatus is rendered responsive by a timing circuit 10 which operates in response to a protective trip signal from the system when a fault occurs to close operating switches 14, 29, 30 for approximately two cycles. Signals from a current transformer (4) in the monitoring station are applied via a transformer 13 to a relay 15, which changes the position of a moving contact 16 each time the current passes through zero. This interrupts the build-up of voltage on the condenser 31 from the voltage transformer 21 coupled to the system, by shorting out the voltage normally applied via an appropriate diode 22, 23 across the Zener diode 24, until the voltage itself changes polarity. Thus a voltage builds up on the capacitor 31 corresponding to the voltage on the system at current zero. The system current transformer (4) is also connected via a transformer 32 to a differentiating network including the capacitors 34, 35 and inductors 37, 38, which also includes the diodes 39, 40 acting to conduct alternate half cycles, to present a steep wave front to the appropriate coil 37, 38 to produce peaked impulses whose amplitudes represent the derivative of current at each zero transition. These pulses are applied to the capacitor 42. The ratio between the voltages on the capacitors 31, 42 is measured in a ratio determining stage 12. This stage is initially set up with the switch 48 in position A and the capacitors 31, 42 discharged, resistor 54 being adjusted to give zero reading on the indicator 52. When a fault occurs and the timing circuit is energized, capacitors 31, 42 charge as described above. With the switch is position B, potentiometer 45 is adjusted to balance the meter, so that the potentiometer is balanced against a voltage corresponding to <SP>dT</SP>/ dt ). The switch is then moved to position C and potentiometer 46 adjusted to rebalance the meter so that the potentiometer is balanced against V. The setting of the potentiometer 46 directly indicates the ratio of V to <SP>dT</SP>/ dt . This gives the inductance of the system between the monitory station and the fault, which is compared with known system parameters to indicate the distance to the fault.
