Title: Improvements in or relating to Keyboards for the Production of a Succession of Control Signals
IPC: H04L13/16
Filed: 1968-03-06
Abstract: 1,170,398. Keyboards for typewriters. SIEMENS A.G. 6 March, 1968 [7 March. 1967], No. 10779/68. Heading B6F. Keys operating electrical contacts: interlocks.- A typewriter or like key 2 is operative to close electrical contacts 9, 10 whereby the current in the windings 3 of electromagnets relating to further keys is increased so that actuation of the further keys is rendered more difficult. The key button 2a may be formed with a shoulder 2e which engages a compression spring 12, depression of the key exerting a downward force on a ring 5 to which a radially magnetized ring shaped permanent magnet 6 adheres by magnetic attraction. The ring 5 is also attracted to the core 4 of the electromagnet so that sufficient pressure must be exerted to overcome this attraction, whereupon the ring magnet 6 may be depressed further, against a spring 11, to surround a fixed magnetizable pin 9 sealed by a fused glass joint 8 into a gas-filled sealed container 7 within which a magnetizable flexible spring contact 10 is fixed. When the ring magnet 6 is depressed into proximity with the pin 9, flux induced in the pin attracts the spring contact 10 towards the pin 9, so closing a circuit including all the electromagnets relating to the keys. Closing the circuit effects an increase in the current to the windings 3 by discharge of a condenser (Fig. 2, not shown) or by transistor action (Fig. 3, not shown), thus rendering more difficult separation of the rings 5 of other keys from the corresponding electromagnets. In a further embodiment (Fig. 1, not shown) the spring 12 is dispensed with and engagement of the shoulder (2e) with the ring (5) effects separation of the ring from the electromagnet. In a still further embodiment (Figs. 4-6, not shown) the keys (15) of a keyboard are arranged in line behind one another between respective pairs of yokes (14) of a comb-shaped core structure, each pair of yokes having a corresponding winding (13, 123), and each key (15) having associated therewith a bar-shaped armature (16, 17, 18, 19) which must be separated from its corresponding pair of yokes (14) to operate the respective key function. The yokes may be laminated, each lamination (20- 23), Fig. 7 (not shown) corresponding to a key. An unlocked key may be provided with a mechanical detect.

In a railway vehicle underframe a central automatic coupler 31, Fig. 1, is carried by a cast steel reticulate and triangulated component 10 so that draft and buff forces are transmitted from the coupler to load carrying underframe beams 2, 3 on or near the centre lines of the side buffers 4, 5 and axle box guides (not shown). The component 10 comprises tubular rectangular box section beams 11 to 15 and cross-pieces 17, 18, the latter forming with the beams 15, 16 a recess 21 to receive the coupler cushioning device 22. The beams 11, 12 and 13, 14 are connected respectively to the ends of the beams 15, 16 and converge into end pieces 19, 20. A free space 27 in the component facilitates movements of the coupler link 28. The cushioning device 22 abuts shoulders, e.g. 23, 24, at the ends of the recess 21. The component is welded to underframe cross-strip 6, 7, stringers 8, 9 and at 19, 20 to members 36, 38 and 37, 39 on a header bar 1 adjacent the buffers 4, 5 and the beams 2, 3. The header is provided with a central opening (35), Fig. 3 (not shown), to permit vertical and horizontal movements of the coupler tail 42 which passes therethrough. In a modification described with reference to Fig. 12 (not shown), a coupler having a tail, formed as a piston and cylinder with an elastic element therebetween is pivoted to the component 10 adjacent the end formed with the cross-piece 18.

Title: Epoxyalkoxy aryl resins
IPC: C08G59/08
Filed: 1951-05-09
Abstract: A synthetic resin contains at least three units <FORM:0721149/IV (a)/1> in which R is hydrogen, alkyl, alkylene, aryl, aralkyl, alkaryl, cycloalkyl, formyl, or furyl; X and Y are hydrogen, alkyl or hydroxyl; R1 is alkyl, aralkyl, alkaryl or cycloalkyl; Z is hydrogen or epoxyalkyl of the formula <FORM:0721149/IV (a)/2> in which the value of n does not exceed 8 and the unoccupied valencies are satisfied by hydrogen or alkyl of not more than 7 carbon atoms, the total number of carbon atoms in the epoxyalkyl group not exceeding 10.  There is at least one epoxyalkyl group per resin molecule.  The products are formed by reaction of a haloepoxy-alkane with an alkali metal salt of a fusible aldehyde condensation product of a hydrocarbon substituted phenol.  Lists of suitable aldehydes and phenols for preparing the initial condensates are given.  Preferably 0.75-0.8 mol. of aldehyde is used per mol. of phenol.  Acid or alkaline catalysts may be employed.  Up to 25 per cent by weight of the total phenol content may be a monofunctional phenol, e.g. 2,4-dimethyl phenol.  Minor amounts of phenols with a functionality greater than 2, e.g. phenol, m-cresol or resorcinol may also be included.  The phenol-aldehyde condensates is dissolved or dispersed in alkali and sufficient haloepoxyalkane added to give the required degree of substitution.  If all the phenolin hydroxyl groups are to be replaced, an excess of 1 mol. over the stoiochiometric amount of haloepoxyalkane should be employed.  If desired, some of the phenolic hydroxyl groups may be etherified or esterified before the reaction with the haloepoxyalkane.  Suitable etherifying agents are methyl chloride, isopropyl chloride, benzyl chloride or dimethyl sulphate. Suitable esterifying agents are carboxylic acids, esters, anhydrides or acid chlorides, e.g. a drying oil fatty acid.  Suitable haloepoxyalkanes are epichlorhydrin, 1-chloro-2,3-epoxybutane, 1-chloro-3,4-epoxybutane, 2-chloro-3,4-epoxybutane, 1-chloro-2-methyl-2,3-epoxypropane, 1-bromo-2,3-epoxypentane, 2-chloromethyl - 1,2 - epoxybutane, 1 - bromo - 4-methyl - 2,3 - epoxybutane, 1 - bromo - 4-methyl - 3,4 - epoxybutane, 4 - chloro - 2-methyl - 2,3 - epoxypentane, 1 - chloro - 2,3-epoxyoctane, 1 - chloro - 2 - methyl - 2,3-epoxyoctane, 1 - chloro - 7,8 - epoxyoctane, 1 - chloro - 2 - methyl - 4,5 - epoxyoctane, 1 - chloro - 2,3 - epoxydecane and 1 - brom-9,10-epoxydecane.  A resin required for cross-linking another polymeric material should have at least two epoxyalkoxy groups per molecule.  Resins with as little as one epoxy group per molecule may be crossed-linked with a polymeric material containing reaction hydrogen atoms.  The resins may be increased in molecular weight by coupling through the epoxy groups.  In the example p-cresol is condensed with aqueous formaldehyde and the product dispersed in caustic soda solution.  Epichlorhydrin is added at 70-80 DEG  C. and the mixture warmed to 85-100 DEG  C.  The resin layer is separated after cooling from the aqueous layer.
