Abstract: 1,087,131. Circuits employing bi-stable magnetic elements. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 5, 1964 [May 22, 1963], No. 20438/63. Heading H3B. A laddie having an odd number of rungs, there being at least five rungs, has a control winding on the third rung and if there are more than five rungs on successive odd-numbered rungs excepting the output rung, there being no control windings on the even numbered rungs. The windings are arranged on the ferrite core limbs in the manner shown in Fig. 2 and the arrows represent the flux distribution after a reset pulse has been applied to the reset windings and before a set pulse has been applied to the set windings. After a set pulse has been applied such as to tend to reverse the residual flux in rung 1 the flux distribution is as shown in Fig. 3 when all the control windings are energized. Since the only available path for the flux in these circumstances is through output rung 9 an output pulse is induced in the output winding indicative of the fact that all control windings are energized. If control winding 1 is de-energized when the set pulse is applied then since the flux in rung 3 is zero, Fig. 4, irrespective of whether or not there is a fault such as a crack in the core or a short-circuited turn, the flux path due to the set pulse will be through this rung and not the output rung 9 so that no output signal is induced in the output winding. The reset winding may be concentrated on the end window, Fig. 5 (not shown), and the side limbs may be of increased cross-section relative to the cross rungs, Fig. 6 (not shown).

Abstract: 1425671 Error correction systems INTERNATIONAL BUSINESS MACHINES CORP 10 May 1974 [26 June 1973] 20659/74 Heading G4A Data are transferred between a data bus and a store via a transfer circuit which effects conversions between byte parity encoded data on the bus and error checking and correcting (ECC) data in the store, and the transfer circuit modifies the ECC bits presented to the store on detecting an error condition in data supplied by the bus during a write operation whereby the error condition on the bus may be recreated on subsequent read-out of the data from the store at which time the program which originated the erroneous data may be more readily identified, The ECC coding preserves the ability of the system to correct single errors and detect double errors originating in the store and to detect errors additional to a data bus error. In a write operation, Fig. 2, eight parity encoded 8-bit bytes are supplied to eight pairs of XOR trees 30 via a connection matrix 29 to generate eight ECC check bits on a bus 35 and byte parity error signals on a bus 31. A detector 32 provides an output 34 if a single byte parity error is detected and this output inverts the ECC check bits on bus 35 before combination with the data bits on bus 38. Detection of a multiple error at this stage results in an output 33 calling for immediate suspension of the current data processing to handle the error condition. In a read operation, Fig. 3, the data and ECC check bits are supplied to the XOR trees 30 via matrix 29 to generate eight byte parity bits on bus 35 and eight syndrome bits on bus 31. The syndrome decoder 42 has an output bus 46 for correcting, 47, single errors in the data bits on bus 64 or the generated parity bits on bus 35 and an output 43 signifying multiple errors and calling for immediate suspension of processing. A further output 44 of decoder 42 is activated in the event that the ECC check bits were inverted during a previous write operation, this resulting in seven of the syndrome bits assuming the value 1, and the generated parity bits on bus 35 are inverted at 36 to re-create the original byte parity error which will be recognized by the data processing system for corrective action to be taken. The arrangement also has the advantage that processing is not interrupted unless erroneous data, e.g. intermediate results, are actually called from store for use.

Title: Improvements in snap-action electric switches
IPC: H01H37/66
Filed: 1933-07-22
Abstract: 423,241. Partly magnetic thermal switches. PIPER, T. W., Hillbury, Redbourn, St. Albans, Hertfordshire. July 22, 1933, No. 20674. [Class 38 (v)] A thermal switch having magnetic means for providing a quick - action, comprises a bimetallic strip 4 carrying at its free end an armature 3 adapted, in the on and off positions of the switch, to engage adjustable stops 7 on polepieces 2 of a permanent magnet 1. A rod 8 passing loosely through a hole in the armature 3 is fitted with stops 9 and is connected to a pivoted arm 5 carrying a contact bridge 11 having wiping engagement with fixed contacts 6. When the bimetallic strip 4 heats up it bends until it overcomes the force of attraction of the armature 3 which moves rapidly upwards and strikes the upper stop 9. The kinetic energy of the armature is sufficient to overcome the contact friction and to ensure a quick-action, the armature then resting on the upper stops 7 on the polepieces.

Abstract: 482,368. Laying or levelling soles. COMPO SHOE MACHINERY CORPORATION. July 27, 1936, No. 20715. Convention date, July 26, 1935. [Class 17 (i)] An inflatable pad for a sole affixing, sole levelling, channel laying or like machine is formed of moulded rubber with side walls of such thickness as to be flexible but not markedly extensible. The upper wall or diaphragm of the pad has forepart and shank-engaging portions 16, 17 moulded in general conformity to the longitudinal and lateral contours of a shoe bottom, and a flat heel-engaging portion 18. The upper wall is reinforced throughout by a fabric layer 20. The heel portion is rendered relatively inflexible by an embedded metal plate 18<1>, and the upper wall laterally of the heel portion is thinned as at 40, so that the portion 18 rises bodily against the heel seat of a shoe when pressure fluid is admitted to the pad. The portion of the upper wall engaging the toe is made of increased flexibility by dividing the upper wall into thin and thick layers 23, 24 which enclose a space 22 connected to the interior of the pad by a port 27. When pressure fluid is admitted to the pad, it acts at once in the space 22 to press the part 23 against the toe of a shoe, while pressure against the entire sole gradually develops. The extreme rear end 43 of the pad is solid.

Title: Separation of solid particles by electrophoretic means
IPC: C25B7/00
Filed: 1957-07-03
Abstract: 869,367. Separating particles from suspensions electrophoretically. AUSTRALIA, COMMONWEALTH OF. July 3, 1957 .[July 9, 1956], No. 21041/57. Class 41. Particles to be separated are suspended in an insulating carrier liquid of high electrical resistivity, and are coated with a charge modifying substance added to the suspension by which the particles move in a desired direction to an electrode when an electric field is applied, which electric field is of a magnitude insufficient to cause ionisation of the carrier liquid. In Fig. 1 particles 1, 2 are suspended or dispersed in a carrier liquid 3 contained in an insulating vessel 4. Electrodes 5, 6 are disposed at a distance greater than that at which ionisation or arcing occur e.g. in the case of carbon tetrachloride and a voltage of 15,000, the electrodes are 1 inch apart. The added coating material imparts a change in the inherent electric charge on the particles which are separated by moving to the electrode of opposite polarity or of different charge value. A removable screen, e.g. a paper sheet or metal surface, may be introduced between the electrodes, and thus become coated with particles of different nature on each side. In a continuous separation process, Fig. 6, mixed coated particles and carrier liquid pass through a pipe 12 into the container 4. Belts 24, 25 are supported on rollers 14, 18 forming electrodes, and a voltage is applied between the fixed electrode 5 and roller 14, and similarly between electrode 6 and roller 18. The particles separate and collect on belts at 7, 8 and are removed by scrapers 22, 23. Particlefree liquid is discharged through a pipe 13 and is re-used. In a further modification, one electrode is formed by a conductive lining to a vessel having an insulated casing, and a tubular member mounted therein comprises the other electrode. The particles to be separated may be mixtures of mineral substances, emulsified particles e.g. paints and pigments, and the charge modifying substance may be a dye, resin, oil, wax or gum. For examples, it is stated that dispersed particles of copper sulphate, " Monolite " (Registered Trade Mark) pigments, cotton fibre and cadmium sulphide in CCl 4  are attracted to the negative electrode, the addition of gum dammar emulsion reverses the inherent charge and the particles move to the positive electrode. The reverse is the case with shellac, calcium carbonate, sulphur, lithium hydroxide and when talc is used as charge modifying material. A mixture of antimony sulphide and calcium fluoride suspended in CCl 4  is thus separated using added beeswax.

Class 106 (ii)]   On an aircraft the air-speed indicator and the rate-of-climb indicator are combined in a common casing, the first instrument being mounted to be rotatably adjustable. The pointers of the instrument are either arranged on a common axis or to avoid friction on two axes lying near one another as in the form illustrated. The air-speed pointer a pivoted at c moves over the dial plate h of the speedometer which is rotatable by turning the knob k, while the rate of climb pointer b pivoted at d moves over a fixed dial plate i slits corresponding to the size of the attaching means allow movement of the dial of the air-speed indicator. The pivots c, d are joined by a phospherescent bar f. When on a long distance flight the rate of climb pointer is at zero, the air speed pointer is adjusted to the Horizontal line formed by pointer a, bar f, and pointer b to secure uniformity of flight with respect to these factors.
