Title: Improvements in high potential electric switches
IPC: F02P15/12
Filed: 1931-12-03
Abstract: 386,095. Sparking preventing in switches. SIEMENS-SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. Dec. 3, 1931, No. 33559. Convention date, March 11. [Class 38 (v).] A current switch S, designed to interrupt currents at low voltage only, but capable of carrying large currents during normal working, is connected in parallel with a power switch L designed to interrupt large currents at high voltage, and the power switch circuit is provided with a choke D, the reactance of which regulates the distribution of current between the switches during normal working, but is greatly reduced on the occurrence or cutting out of a shortcircuit by corresponding proportioning or controlling of its inductive flux. The switch S is closed after the switch L, but opened before it. The choke D is arranged to be saturated by a current well below the short-circuit current value, so that when short-circuit current flows the current to be interrupted by the switch S, and the potential across it in the open position, are greatly reduced. If the resistances of the two switch loops are normally such as to give a proper current distribution, it is necessary to provide a choke for the current switch loop, which is not saturated on the occurrence of a short-circuit. In a modification both switch loops have chokes with secondary windings connected in opposition. When a shortcircuit is interrupted, the opening of the switch S reduces the reactance of the power switch loop.

Filed: 1962-09-04
Abstract: <PICT:0942736/C1/1> <PICT:0942736/C1/2> In the simultaneous bending of more than one glass sheet superimposed on a bending mould in which the sheets are passed through a bending furnace and the initial heating tends to separate the unsupported side edges to leave a gap there-between, the heating of the unsupported side edges during the initial heating is retarded, as by a screen or curtain opposite and immediately adjacent the peripheral unsupported edges, whereby spoiling of glass from the edges and entry of glass particles or dust between the sheets is substantially eliminated.  Glass sheets 13, 14 are supported at each end of the usual three part bending mould 12 carried by pivoted arms 26 from uprights 19.  Support rods 30 either side of the mould 12 are carried by brackets 32 from uprights 19 so that a curtain 34 hung therefrom lies in contact with the unheated sheets 13, 14 along the whole length of the unsupported side edges and will cover the gap 29 caused by the initial heating.  Further heating closes the mould as the glass sheets sink into contact therewith. The curtain 34 may be a flexible interwoven material such as glass fibres or a screen of thin imperforate metal sheet may be used.

Abstract: 745,606. Statistical apparatus, counting- apparatus. POWERS-SAMAS ACCOUNTING MACHINES, Ltd. Nov. 3, 1954 [Dec. 7, 1953], No. 34030/53. Class 106 (1). A counter comprises actuating means operable by alternating electric current, a toothed wheel supported for angular movement about the axis thereof, and an escapement connected with the actuating means for operation thereby, and co-operating with the toothed wheel to effect angular movement thereof by a single tooth-increment for each cycle of alternating current applied to the actuating means. Referring to Figs. 1 and 2, a toothed wheel 20 is supplied for angular movement about its axis and is arranged to be moved angularly by single tooth increments each tooth representing a unit. In Fig. 2 the toothed wheel 20 is provided with ten teeth 21 representative of the numbers 0 to 9 but this may be varied as for pence or tens of shillings. Angular movement of the wheel 20 is effected by an escapement formed by a U-shaped element 23 supplied for rocking movement about a pivot 24 located near the centre of the base of the U-shaped element and landed by a yoke 25 extending from a wing portion 26 of the bracket 22. The free ends of the limbs of the U-shaped element 23 are so disposed in relation to the teeth of the wheel 20 that on rocking about its pivot 24 the limbs cooperate alternately with the toothed wheel to effect single toothed incremental movement. Operation of the escapement is effected by actuating means comprising a permanent magnet 27, Fig. 1, housed in a soft iron case 28 carried by the wing portion 26 of brackets 22, a soft iron inner pole-piece 29, a soft iron washerlike outer pole-piece 30 the base of which forms an air space 31 a coil wound former 32 supported by the inner pole-piece for axial movement in the air-space 31 and a reciprocable connecting element in the form of a wire 33 connecting the former 32 with escapement 23. In operation, when the terminal 35 is positive with respect to terminal 36 the coil-wound former 32 is urged downwards as viewed in Fig. 2 and when terminal 35 is negative with respect to terminal 36 the former 32 is urged upwards. Thus through wire 33 the escapement 23 is rocked about pivot 24 first clockwise as viewed in Fig. 2 so that the wheel 20 moves one half tooth in a clockwise direction and then counter clockwise so that the other limb is restored to co-operating relation with the wheel causing another half tooth movement thus completing the angular movement of one tooth. Specifications 707,736 and 738,100, [both in Group XV], are referred to.

Title: Improvements in or relating to the separation of the constituents of organic-inorganic addition compounds
IPC: C07C51/487
Filed: 1936-12-11
Abstract: The constituents of an organic-inorganic addition compound having different constantboiling compositions at different pressures are separated by distillation under at least two different pressures. The acetic acid-boron fluoride complex obtained by reacting CO with methanol in the presence of BF3 may be distilled at subatmospheric pressure, e.g. 15-20 mm., until 10-15 per cent of the acetic acid distils leaving a constant-boiling mixture.  Distillation is then continued at about atmospheric pressure, boron fluoride coming over until the original composition is attained.  By repeating the cycle, complete separation is obtained.  Addition compounds of other aliphatic acids, e.g. formic, propionic, butyric, isobutyric and higher acids, with boron-halogen compounds generally, may be similarly treated.  Examples describe the treatment of the complex approximating to 2CH3COOH.BF3, distillation being effected alternately at 70 DEG  C. and 15 mm., and at 150 DEG  C. and 760 mm. or higher.ALSO:The constituents of an organic-inorganic addition compound having different constant boiling compositions at different pressures are separated by distillation under at least two different pressures.

Filed: 1960-10-05
Abstract: 933,784. Supply systems for discharge lamps. THORN ELECTRICAL INDUSTRIES Ltd. Oct. 5, 1960, No. 34224/60. Class 38 (4). Current sufficient to pre-heat filaments 13, 16 of tri fluorescent or other discharge lamps 14, 17 to an adequate starting temperature is supplied from mains terminals 10, 18 through a series circuit including filaments 13, 16, the primary winding 11 of a transformer 12, and a capacitor 15. The current induced in the secondary windings 25, 26 pre-heats the other filaments 24, 22. The primary winding volts drop sufficiently low to enable an adequate starting voltage to be applied to the lamps through chokes 21, 23. When the lamps strike, the discharge current of lamp 14 flows through filament 16 and choke 23, causing this current to lag and as the current through this filament by way of capacitor 15 leads the supply voltage, partial cancellation of the current occurs in the effective heating current for filament 16 is reduced. Similarly the effective current through filament 13 is reduced and thus by virtue of the now reduced current through transformer winding 11, the current through filaments 24, 22 is also reduced. Starting aids in the form of earthed conducting members 19, 20 extend the full length of the tubes and are spaced about 1/2 inch from them.
