Title: Key-board signal encoding system
IPC: H03K17/98
Filed: 1973-07-04
Abstract: 1426602 Keyboards INTERNATIONAL BUSINESS MACHINES CORP 4 July 1973 [31 July 1972] 31853/73 Heading G4H A keyboard signal encoding system comprises a co-ordinate array of selectively actuatable keys, and means decoding the output of coded address generating means to select one of a system of conductors associated with a first co-ordinate of the array and one of a system of conductors associated with a second co-ordinate of the array to deliver a signal to a signal detector when the thus selected key is actuated, and output means producing a corresponding coded output in response to the signal detector and the address generating means. The address generating means may be a read-only store which addresses itself and can be caused to branch in the addressing sequence, the read-only store providing key addresses and corresponding coded outputs, or a binary counter could be used as the address generating means, and a data encoder could be provided for the output from the keyboard. The key array is, e.g. capacitive, and gated row amplifiers of the key array are selected in turn and while each is selected the columns of the key array are selected in turn and each driven with two consecutive pulses. If the key is actuated each pulse should exceed a threshold in the signal detector. After thresholding, the pulses set respective periodicallyreset bi-stables which are compared to detect arrival of both the two pulses. Once this has been detected, the threshold is lowered for the time of the second pulse in each pair thereafter to ignore bounce on key release. Multiple outputs from a single actuation of a key are prevented (except when required) using a sequence of registers, each capable of holding a key address, and each feeding the next in the sequence, the current key address being EXCLORed with the output of the last register to feed the first register, the whole loop recirculating twice for each key interrogating period so that each address is compared with all the addresses stored in the loop. An OR gate detects a non- zero content in the first register, and another OR detects a non-zero content in the last register and an "enter key address" input can be applied to the first register. If the currently-addressed key is actuated and its address is not in the loop it is inserted in the loop and the coded keyidentifying output is provided from the system. If the key is not actuated and its address is in the loop it is erased from the loop. If the key is actuated and its address is in the loop, it is left in the loop.

Title: Improvements in or relating to the production of laminated articles
Inventor: STAUDINGER JOHANN JOSEF PETER
IPC: B32B27/00
Filed: 1953-11-18
Abstract: A bonding composition comprises an unsaturated polyester resin, a monovinyl aromatic compound and a finely-divided vinyl chloride polymer containing a major proportion of vinyl chloride units, preferably the diameters of the major proportion of the particles being in the range 0.01 to 20 millimicrons.  Unsaturated polyester resins specified are the allyl or substituted allyl alcohol esters of phthalic, adipic, succinic and sebacic acids, glycol esters of unsaturated acids, such as maleic, fumaric, itaconic and citraconic, with or without saturated dicarboxylic acids (including endomethylene tetrahydrophthalic and hexachloro-endomethylene tetrahydrophthalic acids).  The aromatic monomer may be styrene, vinyl toluene, a -methylstyrene or a mono- or dichloro-, or alkoxy- or hydroxy-styrene.  In Example 4 di-allyl maleate is included in addition.  The polymer is preferably stirred into the mixture by means of a mixer which does not stir in high proportions of air. Specified polymers are polyvinyl chloride and copolymers of vinyl chloride with vinylidine chloride, vinyl acetate and acrylonitrile, preferably produced by emulsion or dispersion processes.  The bonding compositions may be cured by heat alone or by catalysts such as benzoyl, lauryl and methyl ethyl ketone peroxides and isopropylbenzene, t.-butyl benzene and 1-hydroxy cyclohexyl hydroperoxides.  Promoters such as dimethyl, diethyl and di-n-propyl anilines, dimethyl-p-toluidine, diethyl-a -naphthylamine, p-dimethylamino azobenzene, dimethyl m-aminophenol, cobalt and manganese naphthenates may also be used and inhibitors such as hydroquinone, a -naphthol, t.-butyl catechol, benzaldehyde and tetrachloroquinone may also be included.  Mixing of the composition may be improved by the use of dispersing agents such as soaps, sodium salts of sulphur containing organic compounds, longchain fatty alcohols and polyethylene oxide, and other optional additives are fillers, e.g. silica, clay and whiting, pigments, dyes and plasticisers.  The compositions are inherently thixotropic and are useful for bonding (laminating) at temperatures below 80 DEG  C., materials such as cotton, cellulose pulp, glass fibre cloth or mat, asbestos and slag-wool, to give products such as boats, tubes, ducts, car bodies and aeroplane parts.  The bonding is preferably carried out so that the temperature at any point within the article does not rise above 100 DEG  C.  Examples describe the production of glass cloth laminates of improved physical properties.

Title: Improvements in and relating to electron discharge tube circuits
IPC: H03F3/48
Filed: 1948-12-10
Abstract: 656,929. Valve amplifying and generating circuits. COSSOR, Ltd., A. C., and COVILL, D. H. Dec. 10, 1948, No. 32072. [Classes 40 (vi)] [Also in Group XL (b)] A pentode or other multigrid valve is connected so as to operate as a two-stage cascade amplifier; the second grid acts as the anode of the first stage, having a load resistance R1 and is coupled by a condenser C2 to the suppressor grid, which forms the control electrode for the second stage. The output is taken from the anode, the output load comprising a further resistance R2 in series with the resistance R1. Bias is applied to the control and suppressor grids by means of cathode resistances R4, R5, the control grid being given the lesser bias by returning its leak resistance to the join of resistances R4, R5. The input and output of the amplifier being in the same phase, feed-back over the interelectrode capacity between the first and second grids may be neutralized by connection of a condenser between first grid and anode. A further modification comprises a D.C. amplifier in which the resistance R3 is omitted and the condenser C2 replaced by a floating battery. The arrangement may be used in a television receiver (see Group XL (b)) as an in-phase amplifier and also to provide D.C. restoration. Another modification Fig. 5 (not shown), comprises a push-pull driving circuit, the two outputs being obtained respectively from the anode and suppressor grid; balance is adjusted by returning the suppressor grid to a tap on the resistance R3. The arrangement may also be used as an oscillator by providing a feed-back path between anode and first grid, comprising resistance and capacity in series together with like elements connected in shunt between first grid and ground. Specification 600,884 is referred to.

Abstract: 896,670. Variable-speed gear. BENDIX CORPORATION. Sept. 19, 1960 [Oct. 5, 1959], No. 32171/60. Class 80 (2). [Also in Group XXXI] A two-speed gear for velocipedes which is shifted by momentarily back-pedalling comprises a driving-sprocket 22 fast with a highspeed shaft 6 having a threaded connection with a coned clutch member 18 frictionally engageable with a surface 21 on a wheel hub 8. The sprocket 22 is fast with a ring gear 23 of a planetary reduction gear having a permanently stationary sun and a planet carrier fast with a low-speed shaft 5 having a threaded connection with a coned friction clutch member 17 engageable with a surface 19 on the hub. The clutch member 18 is formed with an axial extension 36 formed with peripheral ratchet teeth 37 and a facial cam, the number of crests 39 of which is equal to half the number of the ratchet teeth 37. A sleeve 32 is frictionally swivelled on the shaft 6 by spring arms 33 engaging a groove 34 in the shaft, and has pawl arms 35 engaging the ratchet teeth and inwardly-directed projections 38 cooperating with the facial cam. In the position shown, the projections 38 register with troughs 41 of the cam and the clutch member 18 is permitted to engage to drive the hub at high speed. Momentary back-pedalling causes reverse movement of the shaft 6, but not of the clutch member 18 due to a frictional connection of the member 18 with a stationary anchor member 2, and the pawl arms 35 are caused to snap over one ratchet tooth 37. The crests 39 of the cam are now aligned with the members 38 which consequently prevent engagement of the clutch member 18 upon subsequent forward rotation of the sprocket 22. The low speed clutch member 17 is thus permitted to engage.
