Abstract: 1287370 Magnetic storage arrangements INTERNATIONAL BUSINESS MACHINES CORP 30 Nov 1970 [24 Dec 1969] 56858/70 Heading H3B [Also in Division G4] A decoder comprises a plurality of pairs of magnetic switching elements, input signals switching one of each pair, a plurality of output means each receiving a signal from each element which switches, the latter signals failing to substantially cancel each other on only one of the output means for each combination of input signals. In Fig. la, toroidal magnetic cores 112-115 are biased to one end of their hysteresis loops by a bias current source (or restore pulses may replace the continuous bias). Two input bits, at 106, 107 respectively, each switch one (depending on the bit value) of cores to the other end of its hysteresis loop, using drive windings 108-111. Output windings each thread every core in one sense or the other depending on the input combination the winding is to recognize. Each pair of drivers, such as 100 -101, may be replaced by one, with one drive winding threading the cores in opposite senses and going to ground (or going to another output of the driver), or the single driver (for the pair of cores) may have two drive windings threading respective cores and going to ground. A preliminary decoder is given in block diagram (logic) form to convert a 2-bit input into signals on 8 leads to drive a decoder having 4 pairs of cores. This 4-pairs decoder may be expanded to have 4 sets of 4 pairs of cores each, the 8 leads above being X leads common to all the sets, and each set having a respective further drive winding (Y lead) threading all its cores, one of the further drive windings being energized, thus (with the 8 leads) providing coincident current selection. This two-dimensional array may be one plane of a three-dimensional array. The function of the bias winding may be taken over by these further drive windings. The cores may be replaced by magnetic film spots, or toroidal films. Coincident current selection may alternatively be done by wiring the Y leads according to the same scheme (in the Y direction) as the X leads are wired (in the X direction). The decoder can be used for energizing half-select lines in a magnetic memory.

Title: Devices for Heating Food Contained in Coded Packages.
Inventor: TANGUY PIERRE
IPC: F24C7/02
Filed: 1967-12-14
Abstract: 1,180,958. Electric heating. P. TANGUY, P. CARRE, and J. LE BOULBOUECH. 14 Dec., 1967, [15 Dec., 1966], No. 56878/67. Heading H5H. [Also in Divisions G3, H1] A device for heating food contained in packages is automatically controlled in response to the reading of coded irregularities on the surface of the package. A coded food package, Fig. 1, comprises a bottom 1 and a cover 2. The edges of the bottom on which the cover is glued are cut away as shown, a jag 4 determining the heating time and jags 3, 5 set the intensity of heating and control of other apparatus connected with the heating. The coding may also be effected by recessing the bottom or, for cans where indentations are formed to compensate for the partial vacuum created during sterilization, by additional coding indentations formed during stamping. As shown, Fig. 6, a package 12 is introduced into an oven on a support 13 between infra-red emitting elements 14, 15. The oven shell 16 is insulated by glass-wool. The package is introduced into the oven through an insulated door 18, locked by an electromagnet, having a pressure blade 19 retaining the package in place. Each line of indentations on the package 12 is sensed by a feeler 22, pivoted about a shaft 24 and loaded by a spring 25, the tension of which is adjusted by a cross-piece 26 cooperating with a variable stop 27. An end 28 of the feeler 22 bears on an adjustable rod 29 which exerts a load, when the feeler is not engaging an indentation, on a switch 30 controlling resistances 32. The resistances are placed in series when the feeler engages an indentation and are placed in parallel when it does not. The resistances 32, through a capacitive circuit, determine the time of heating of the coded package. The feelers are arranged along the shaft 24 and through a linkage operated by the package, Figs. 7-9 (not shown), are lowered during insertion of the package and only touch the bottom of the package when it is in the stop position. Current for pre-heating the oven is determined by a contact inserting, through an electromagnetic relay, resistances in the capacitive circuit, a lamp being energized on release of the relay to denote the oven is ready for operation. At the end of a heating cycle the door 19 opens, on release of the electromagnetic lock, by the pressure of a bar 39 on the package. In another embodiment, a package, coded as in Fig. 1, is positioned between a pair of highfrequency electrodes, the lower one of which is positionable in dependance on the length of a jag to vary the intensity of heating. Additional feelers, responsive to the package code, are stated to modify the programme of a device for making pancakes. In a further embodiment, the door is retained by an electromagnet against the pressure of a spring, which, when the electromagnet is deenergized, opens the door and ejects the package.

Abstract: 1,207,979. Fluid-pressure servomotor systems. ROBERT BOSCH G.m.b.H. Dec.29, 1967 [Jan. 2, 1967], No.59016/67. Heading G3P. An hydraulic regulator, e.g. a governor for an I.C. engine comprises a piston type accumulator 8 having a spring 22 to bias the piston towards a stop 21 which determines its rest position, element 1 providing a source of liquid under pressure in the cylinder 5 and reciprocated by an engine driven cam (not shown) in accordance with engine speed, a spring-loaded adjusting piston 18 connected to a regulating rod of a fuel injection pump, the element 1 periodically connecting a chamber 9 of the accumulator 8 first to the chamber 5 during the pressure stroke via a passageway 10 and a check valve 11, and also a passageway 4, 3, 12, to stress the spring 22, next to chamber 5 during the suction stroke via the passageway 12 and adjustable throttle 13, and then to the adjuster cylinder 15 via a passageway 16. In the figure the control element is shown in the bottom dead centre position and liquid is supplied from a reservoir 7 to the chamber 5. Upward movement of the element 1 displaces the piston 8 upwards. During the return of the element 1, piston 8 is moved towards a stop 21 until the passage 12 is closed. As long as the speed of the control element does not exceed a predetermined value, set by the throttle 13 which retards return movement of the piston 8, the piston 8 returns to its position of rest before the chamber 9 is connected to the chamber 15 via passageways 16 and 17. Since there is no pressure differential the piston 18 remains at rest. If the speed increases the piston 8 is not able to reach the stop 21 before the passage 12 is closed and the passageway 17 is opened, and the liquid under pressure chamber 9 flows to the chamber 15 to move the piston 18 to reduce the fuel supply to the injection pump. The upward movement of the piston 8 is limited by relief passages 23 and 24. If the speed drops quickly a passage 26 causes accelerated emptying of the chamber 9 and consequently accelerated movement of the piston 18 to increase the fuel quantity. The diameters of the pistons 8 and 18 and the force of their springs are selected so that the pressure required to lift the piston 8 is greater than, or equal to, that required to lift the piston 18. The stops 20 and 21 may be made adjustable. A throttle 25 may be disposed in the passageway 17. The passage 12 may return to the reservoir which is at a low-pressure.
