Title: Improvements in Printing Fabrics and Yarns.
IPC: B41F13/10
Filed: 1917-11-30
Abstract: 119,947. Calico Printers' Association, Clegg, E. B., Farnworth, F., and Roberts, F. Nov. 30, 1917. Printing processes; printing-surfaces: tripping and like arrangements.-In a machine for printing fabrics and yarns, the printing- roller is made of two or more sections, one or more of which are secured to the mandrel and the others loose upon the mandrel and driven from the fixed sections by catches or equivalent devices, with slight lost motion, whereby when the mandrel is adjusted circumferentially, a slight misfitting of the parts of the pattern occur and produce the effect of handblock printing. As shown, the printing-roller is in two sections c, e<1>, the section c being secured to the mandrel d and the section e<1> being driven from the section e by projections f<1> on a member f engaging recesses in a member g secured to the section e'. The mandrel is driven from a gear h on the shaft of the impression cylinder b, meshing with a gear i loose on the hub j<1> of a worm-wheel j fixed to the mandrel d, a worm k carried on the side of the gear i engaging the worm wheel j and having its ends connected by links k<1>, k<2> to arms k<3> of a member k<4> slidable on the hub j. The member k<4> is operated by arms m<1> on a shaft m operated by a hand-lever l and turns the worm k so that the mandrel is adjusted circumferentially to cause the pattern printed by the roller to fit or misfit the patterns already printed on the fabric and the lots motion between the sections e, e<1> causes a slight misfitting of the parts of the pattern printed by the sections.

Title: Dish washer with reversing spray assembly
IPC: A47L15/23
Filed: 1964-04-29
Abstract: 993,692. Dishwashing machines. TAPPAN CO. April 29, 1964 [Oct. 3, 1963], No. 17792/64. Heading A4F. [Also in Divisions B2 and F2] A reversing spray arm assembly for use in a dish-washing machine comprises a reaction type spray arm adapted to receive liquid under pressure, said arm having liquid discharge orifices, means for mounting said arm freely for rotation, means for supplying liquid under pressure to said arm, and means for reversing the direction of rotation of said arm in response to a drop in liquid pressure within the arm. Upper and lower spray arms 70, 72 are mounted in washing chamber 14 containing dish racks 24, 26, the dishwasher 10 also including a depressed sump 30 with a filter cover 32, a circulating pump 54, a drain pump 60, a heating element 62 and connecting piping so that it may operate in a conventional manner. Cleaning fluid passes from pump 54 up through discharge outlet 76 and hose 78 to the plastics two part spray tubes 70, 72 which are rotatably mounted on mounting knobs 138 and 118, then out through the discharge orifices to spray the dishes to be cleaned. One end of the spray arm housing 150 (Fig. 4) is provided with radially spaced series of drive discharge orifices 170 and 172 which communicate with two separate chambers formed by partitions 174 and 180 whilst the other end has formed in it, spaced vertically disposed non-drive discharge orifices 200. Depending through which of the drive discharge orifice series 170 or 172 the fluid passes the spray arm housing 150 will be rotated in a clockwise or an anticlockwise direction. The fluid pumped into the spray arm is put into communication with one or the other chamber communicating with one of the series of drive discharge orifices by a valve assembly 192 which also blocks off communication of the fluid from the other series of drive discharge orifices to enable the housing 150 to rotate. The valve assembly 192 is so constructed that the rotation of the spray arm biases it to close the port through which fluid is communicating with the drive discharge orifices in use and open the port communicating with the other drive discharge orifices so as to reverse the direction of rotation. The fluid pressure on the valve assembly however prevents it from doing this so that this change of rotation can only occur after a drop in fluid pressure usually due to the completion of part of the dishwashing cycle. Other embodiments of spray arms and valve change over mechanisms (see Divisions B2 and F2) are disclosed, including spray arms having drive discharge orifices on both branches of the arms and dual valve mechanisms to actuate the fluid reversals for them.

Title: Data translation apparatus
Inventor: CARTER WILLIAM CASWELL
IPC: G06F11/10
Filed: 1971-05-28
Abstract: 1293488 Error correction systems INTERNATIONAL BUSINESS MACHINES CORP 28 May 1971 [30 June 1970] 17810/71 Heading G4A Parity coded data is converted into error detecting/correcting coded data during a memory write access, and the same equipment is used during a memory read access to convert error detecting/correcting coded data into parity coded data. Memory write access.-Information comprising data bytes and byte parity bits is loaded into registers MR, MDR from a CPU. The parity of each byte in MDR is checked by XOR circuits in the error detect mechanism to produce a word for storage in a syndrome (S) register which should, e.g. be all 1's. If a parity error is detected an output on line 140 initiates a conventional interrupt to cause re-transmission or entry into a diagnostic or error routine. If the word in the S register is correct, the contents of register MR pass through a connection matrix in which selected groups of bits each contain one parity bit, to a set of XOR trees deriving a set of error detecting/correcting Hamming check bits on cable 120. These check bits are combined with the data bytes on cable 122 and gated at 124 by the " no error " signal 126 into register MDR to replace the parity coded data supplied by the CPU. Finally, at the end of the clock pulse controlling transfer to MDR, a " data valid " signal on line 134 effects transfer from MDR to memory. Memory read access.-Data bytes and associated Hamming check bits read out from memory are loaded into register MR. The contents of MR pass through the connection-matrix, which this time includes one check bit in each selected group of bits, to the XOR trees to generate one parity bit for each byte on cable 120. These parity bits are combined with the data bytes on cable 122 and are gated at 124 into the MDR register. The parity of each byte is checked by the XOR circuits in the error detect mechanism, the resulting syndrome word being gated into the S register. If only one bit in the S register is a " 0 " this indicates a single error in a check bit and detection of this condition is used to correct the appropriate bit in the MDR register. A single data bit error is indicated by an odd number of " 0's " (more than one) in the S register, and syndrome decoders detect which bit is in error so as to complement the appropriate bit when the contents of MDR are gated out to MR. Finally, the contents of MR (corrected) are transferred to MDR via the connection matrix and XOR trees to produce the correct parity bits, and the parity coded word is transferred from MDR to CPU.

Title: Improvements to electric automatic control mechanism
Inventor: SPENCER ROLF EDMUND
IPC: G05B19/4105
Filed: 1956-06-05
Abstract: 862,454. Electric copying machines. ELECTRIC & MUSICAL INDUSTRIES Ltd. June 5, 1957 [June 5, 1956], No. 17296/56. Class 38 (6). [Also in Group XXXVI] In order to avoid unwanted small variations in a profile being cut by an automatically controlled machine tool as in Specification 848,411 due to variations in timing between selectors 3, 4 which provide outputs corresponding to sets of X, Y co-ordinates determining the profile to be cut, the stud circles 1, 2 over which the selectors move being supplied with signals from an interpolator as in Specification 796,994, are movable in either direction to compensate for any variation in timing of the selectors. The arrangement is such that the cutter is prevented from crossing the locus being cut and thereby indentations of the workpiece are avoided. In the embodiment shown, a commutator 11, the alternate sectors of which are positioned negative, is arranged to rotate in the same direction and through the same angle as the outward normal to the instantaneous point of contact between the profile and the cutter. If, for example, the place of rotation of 3, 4 (which determines the cutting sense) are such as to cause the profile to be cut always to lie to the left of the forward direction of the cutter, it can be shown that if the outward normal to the profile is in the first or third quadrant, then if the cutter responds to an X-signal an indentation will be produced. This is, however, prevented because under these conditions brush 13 applies a positive potential to rectifiers 14, 15, causing current to flow in solenoids 7, 10, thereby displacing the studs of switch 1 in a backward direction and those of switch 2 in a forward direction and compensating for the amount X is in advance. If brush 13 is in contact with a negative commutator segment, the solenoids 9, 8 will be energized and the switch studs will be displaced in the reverse directions, thereby compensating for any advance of Y-signal over X-signal. A brush displaced at 90 degrees from 13 and both brushes connected through a switch to the rectifiers allows for a reversal of the direction of cut. The invention may be applied to a three-dimensional co-ordinate system.

Title: Improvements relating to the emission and reception of submarine waves
IPC: G01S1/72
Filed: 1920-06-30
Abstract: 145,691. Langevin, P. Sept. 17, 1918, [Convention date]. Signalling proximity of vessels, land, shoals. rocks, and icebergs; subaqueous signals.-A transmitter or receiver of high-frequency (ultra-audible) vibrations, particularly for use in directive subaqueous signalling or for detecting submarines, icebergs, or other echo-reflecting objects as described in Specification 125,122, utilizes the piezoelectric effect of quartz crystal. In simple form, the device comprises a plate of quartz having its faces cut perpendicular to the binary axis and provided with metallic coatings to form a condenser, the crystal constituting the dielectric. Pressure variations due to the received vibrations give rise to corresponding potential-difference variations between the two faces of the crystal, and these can be detected in a circuit connecting the two coatings, as, for example, by heterodyne methods used in wireless signalling. Conversely, when the faces of the crystal are subjected to potential-difference variations from a source having the desired frequency, corresponding vibrations are emitted by the device. Fig. 2 shows a form for submarine use in which a watertight casing e is closed bv a diaphragm f of mica to which a mosaic of quartz crystals a<1> a<2> is cemented. The water in which the device is immersed constitutes one plate of the condenser, a metal plate b secured to the crystals forming the other. The device is resonant to the frequency for which the combined thichness of the crystals and attached plates forms a " half-wave plate." Fig. 3 shows a form in which a thin layer of crystals a is placed between two metal plates g, g<1> of equal thickness, the resonance being secured by suitably choosing the thickness of the metal plates. The casing may contain air, in which case vibrations are transmitted only from one face of the crystals, or may be filled with insulating-liquid, when both faces of the crystals transmit.

Title: New or improved process for the treatment of metals
IPC: C21D10/00
Filed: 1931-06-22
Abstract: In a process for improving the physical characters of metals in which fluctuations in their physical properties such as hardness or ductility occur after a primary thermal, mechanical, or magnetic treatment, the metals are subjected, at a selected phase of such fluctuations, to a secondary stabilizing magnetic treatment, e.g. the application of a stationary or rotating magnetic field or a demagnetizing process.  If the fluctuations produced by the primary treatment have damped out, they are reproduced in the metals by rotating them in a strong magnetic field.  The primary mechanical treatment may be that described in Specification 301,762, [Class 83 (iv), Metals, Working], and the primary magnetic treatment that described in Specification 338,511, [Class 72, Iron &c.].  A second treatment may be applied to the metal at a selective phase of the new fluctuations set up by the first stabilizing treatment.

In apparatus for converting coded input data representing a line of text justified in columns, but which may be a line which is to be printed as a whole or split into two half-column sections, in a first font or system of width measurement, into coded output data in a different font, justified as a whole or in two halves separately justified as is requisite, there is provided means for detecting a signal (e.g. two thin space codes) indicating the centre of a line to be divided into two half-columns, and detecting if said signal is within a range of positions wherein it can have this meaning, and if so justifying the two halves separately, while justifying the line as a whole if no such signal is present in the range. The justification calculations are performed by a computer which calculates the line remainder, number of spaces, and hence required length for each space. Where a line is for two half columns, the first half is read and justified before the second half is read.

Title: Method of and apparatus for encoded communications transmission
IPC: H04L9/12
Filed: 1972-04-19
Abstract: 1388035 Digital transmission; cyphering systems GRETAG AG 19 April 1972 [19 April 1971] 18209/72 Heading H4P In a method of cyphering data, clear text is mixed with a first sequence developed by a programme and transmitted in alternation with a pseudo statistical sequence, the latter being compared on reception with an identical soquence to establish correlation and hence provide synchronization of the first sequence. The first sequence may be determined by first and supplementary codes and the pseudo statistical generator may produce a series of different sequences utilized sequentially; the pseudo statistical sequence may be inserted periodically or aperiodically. Data source 1, e.g. a teleprinter, is connected to line 4 through mixer 3 to which code computer 5 is connectable through switch S3. Cypher computer 5 may be designed to be variable and this must be brought into the same initial condition as a corresponding computer (5<SP>1</SP>) in the receiver. This is achieved by a base code, and a supplementary code generated in computer 8 preferably controlled by date and time. Computer 8 has substantially the same routine as 5 and the date time converter 7 has its output expressed in the decimal terms and feeds separate mixers 9a, 9b through a switch S1 which is closed periodically, e.g. once per minute. Code stores 6, 22 store first and second base codes respectively, the latter passing an output into mixers 9a, 9b which also receive an input from unit 12, the latter being provided for multiple network operation. Switch S1 is closed periodically, e.g. each minute, and output from 7 passes into 9a, 9b to be mixed with output from 22. Each sequence from 9a, 9b resets computer 8, causing it to generate a erypto synchronizing sequence of pseudo statistical form which may be shorter than that generated by 5 and may be selected from a longer sequence. To increase security stores 6, 22 are also controlled by 7 so that the code may be changed periodically, e.g. daily. The output from 8 is connected through store 13 and switch S2 to the input of mixer 14. When it is desired to reset the conditions in 5 a signal from the source 1 is recognized by 15 and is transferred by 16 which reverses switches S2, S3. Alternatively the synchronizing sequences may be inserted automatically into intervals in the data so that the receiver may be reset to the same condition as the transmitter.  Decyphering is carried out in the reverse manner to cyphering. Clock 23 should be independent of the date/time converter 7. At the beginning of a transmission it may be desirous to reverse all the clocks connected to the network by say 2 minutes in order that three successive synchronizing sequences may be received. When communication is established clocks are then advanced again by two minutes by being run at a high speed for a determined period.
