Title: Improvements in or relating to Push-Button Assemblies
Inventor: WILLIAMS JOHN HOWARD
IPC: H03M11/02
Filed: 1967-04-14
Abstract: 1,168,535. Keyboards for printers. OAK ELECTRO/NETICS CORP. 14 April, 1967 [15 April, 1966], No. 17343/67. Heading B6F. [Also in Divisions E2 and H1] A push-button assembly for a computer control panel, for example, comprises several rows R of buttons 10 wherein strips 26 slidable in a channel member 28 prevent more than one button 10 in a row being fully depressed at a time, and associated with each row R is a bar 36 which is displaced when any key in the row is depressed and strips 46 (similar to strips 26), slidable in a transverse channel member 48, prevent displacement of more than one bar 36 at a time; thus only one button in the whole assembly can be fully depressed at a time. The strips 26 (and 46) have stepped cam surfaces at their ends (Figs. 6 and 7, not shown) overlapping by approximately the thickness of the button shanks 30 so that the total displacement when a button is depressed is twice the thickness of shank 30, thus rendering manufacturing tolerances less critical. The bars 36 are carried by pivot-pins 37 on bell-cranks 34 at each end such that a bar 36 suffers similar displacement whichever button 10 in the row is depressed. Arms 44 connected to the bellcranks 34 at one end of each bar 36 displace the interlock sliders 46 when a bar is actuated. The buttons are also provided with a pivoted latch bar 52 engaging notches (66, Fig. 5, not shown), in shanks 30 to hold a button depressed until released by the initial movement of another button. Switch contacts (not described) are operated by the buttons.

Patent GB-649464-A (GB)
Title: Hydrogenation catalysts
IPC: B01J23/80
Filed: 1948-06-30
Abstract: <PICT:0649464/III/1> A disintegration resistant hydrogenation catalyst comprises a minor proportion, preferably from 0.2-10 per cent by weight, of a Group VI or VIII metal, particularly iron deposited on a finely-divided fluidized carrier by the decomposition of the vaporous carbonyl compound of the metal.  The carrier, preferably synthetic spinels such as ZnO.Al2O3, Cr2O3.Al2O3, CuO.Al2O3, or carbonates of Group II metals, active carbons, glass, silica-alumina and silica-magnesia complexes, fuller's earth, clays, or metals such as zinc, copper, chromium, molybdenum, tungsten or iron, may be heat-treated before use and may include from 0.5-10 per cent of selectivity promoters such as K2CO3, NaSiO3, KOH, KF, NaF, KBF4, Na2CO3, &c.  The carbonyl compound is conveniently prepared by contacting finely-divided metal with carbon monoxide under pressure such as 600 pounds per square inch at a temperature below that of decomposition of the carbonyl, generally 250-650 DEG  F.  Preferably this is conducted in a fluidized bed of metal particles of 5-200 microns size, the resulting carbonyl vapours diluted if desired with nitrogen or hydrogen, being contacted with a fluidized mass of carrier material of 20-500 microns size, maintained, in the case of iron at 400-1000 DEG  F. under 1-50 atmospheres pressure.  The decomposition of the carbonyl is preferably effected in the reaction zone of a hydrogenation process as shown in Fig. 2, wherein reactor 220 contains a fluidized bed of iron fed from hopper 201 via pipe 205 or through pipe 211 to pipe 207 through which incoming carbon monoxide passes.  Spent solids are withdrawn at 219 and unconverted iron returned to hopper 201.  The carbonyl vapours separated from solids pass via pipe 228 to pipe 230 to meet inflowing fluidizing gas such as hydrogen or nitrogen, and hence to reactor 250, or, if the reactor is used for synthesis, a synthetic mixture of carbon monoxide and hydrogen in ratio 1-2 : 1, from pipe 245.  Carrier material is fed by line 238 from hopper 232.  The carbonyl vapours may be fed intermittently or continuously, either alternately or together with the synthesis gases.  Alternatively instead of feeding the vapours directly to the reactor they may be absorbed in a cooled recycle stream of fluidized material leaving the reactor via pipe 249 and being cooled before joining pipe 230 at point 262, thus producing a more even deposition.  The Specification as open to inspection under Sect. 91 states that the carrier may be impregnated with liquid carbonyl and decomposition effected by shock-heating.  Decomposition may also be effected by supersonic waves, ultraviolet light or sunlight. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in the sealing of electrically conducting leads through vitreous walls
IPC: H01J5/32
Filed: 1943-10-25
Abstract: 569,317. Uniting metal to vitreous material by heat. GENERAL ELECTRIC CO., Ltd., BREADNER, R. L., and SIMS, C. H. Oct. 25, 1943, No. 17580. [Class 36] A metal cup 1 is sealed to a vitreous wall 4 by heating the opposite side of the wall so that the rise of pressure blows a hole in the wall, the cup having a depth less than its diameter and a rim 2 formed by an out-turned flange. The cup, of nickel-iron, has a pillar 3 which protrudes little, if at all, above the rim 2 and forms an external terminal. To ensure the pressure necessary to blow a blister 5 which becomes a hole in the wall, the cup may hold a small quantity of material, e.g. nitro-cellulose, which yields a gas on heating. It is not necessary to copper-plate the flange 2 to prevent oxidation, but the pillar 3 may be coated with graphite to prevent its adherence to the wall 4. The wall may have a conducting layer subsequently deposited upon it at 6 to make contact with the cup 1. Specification 534,952 is referred to.

[Class 97 (iii)] Apparatus for drawing logarithmic spirals comprises a table 2, Figs. 1 and 2, supporting a disc 3 on which the spiral is drawn. A block 10 slidably mounted on the disc 3 is fitted to a vertical central member 4 and supports in a horizontal bore 11a slidable and rotatable screwed radial arm 5. A wheel 6, Figs. 4 and 5, comprising a chamfered peripheral disc 6a and a stepped spigot 6b is attached to the radial arm by means of a sliding' block 25 held in position by a screw 41. An annular series of punches 9a, Fig. 9, arranged at equal distances, are clamped between the serrated face of a punch plate 9 fitting over the spigot 6b and the back of the wheel disc 6a. These punches protrude beyond the edge of the wheel disc sufficiently far to perforate the disc 3 upon which the wheel 6 rolls. The arm 5 is rotated about the member 4 so that the wheel 6 rolls on the disc 3 and screws the arm 5 inwardly towards the member 4 or outwardly away from it depending on the sense of the screw-thread on the arm and the direction of rotation of the arm 5, the wheel 6 thus traces out a'logarithmic spiral. The wheel 6 may be attached to the radial arm 5 by means of a Hooke's coupling (Fig. 16, not shown). In an alternative construction, Fig. 17, the block 25 is a sliding fit on the radial arm 5 and has an inclined bearing face 25a for the wheel 6. A bevel gear 30 secured to the wheel 6 drives the gear 31, the hub of which constitutes a nut on the radial arm and which is adjustably secured to the member 25 by screws 33. The spiral is graduated-with numbers and a circumferential logarithm scale 36 is constructed on the table 2. The first figure of -the mantissa of the logarithm is given by the ordinal number of the coil on which the coil stands. The subsequent figures are obtained from the circumferential scale 36 and a vernier 34.

Abstract: 178,499. Beaver, C. J., and Claremont, E. A. Dec. 17, 1920. Wire cores, covering by winding.-In the process of lapping the paper spirally on paper-insulated electric cables, pressure is applied radially greater than can be imposed through the instrumentality of tension in the strips of paper. In the construction shown in Fig. 2, pressure is applied to the layers of paper b by pairs of grooved ro'lers c, d supported in bearings under electric pressure. In the modification shown in Fig. 3, a wheel c rotatably mounted on an axle through which passes the cable, carries a spring- controlled flexible chain d carrying rollers d<1> engaging the cable. The wheel c is driven in the same direction as that in which the strips are laid on. In another arrangement, the rollers d<1> are arranged spirally around the conductors. Pressure may also be applied by interposing between paper lappings a lapping of impregnated linen or other fabric which is lapped with a greater tension than could be applied to the paper, or a strip of vulcanized rubber or other elastic material extended by tension mav be laid on the paper lappings and unwound again, thereby compressing the layers underneath. Pressure may also be applied by passing the conductor with paper lappings through a die, further lappings being added before the compressed lappings have time to expand. In a further construction a spring connected to the spool carrier from which the lappings are taken, is arranged to apply pressure immediately behind the lapping strip.
