Title: Improvements in or relating to the manufacture of glassware
IPC: C03B35/06
Filed: 1930-12-01
Abstract: 368,335. Separating or sorting by weighing. ROCKWARE GLASS SYNDICATE, Ltd. and WARDLEY, T., Rockware Avenue, Greenford, Middlesex. Dec. 1, 1930, No. 36201. [Class 143.] Articles of glassware such as bottles or containers or pressed ware are automatically weighed individually during their conveyance from a forming machine to an annealing lehr and only those articles within a predetermined limit of accuracy as regards weight are allowed to proceed to the lehr. The articles a from a forming machine A are carried by an endless conveyer B towards the lehr C, a weighing apparatus D, which may be similar to that described in Specification 344,676, being interposed. The operating mechanism of the weighing apparatus, comprising suitable gearing for effecting the cycle of operations necessary for weighing each article, is actuated by the article striking a tripper E causing it to move and complete the circuit of a solenoid E<1> operating a single revolution clutch. A camoperated pusher F pushes the article on to a support G, from which it is moved by a pusher H on to the table I carried by a weighing beam I<1>. If the article is of incorrect weight the table moves, operating electrical means, for example as described in Specification 344,676, which enable a solenoid or the like K<1> to move a deflector K across the conveyer. After weighing, the article is pushed on to the conveyer again by a pusher J and, if of the correct weight, is carried on to the lehr, while if too heavy or too light it is deflected by the deflector K. The deflector then returns to its inoperative position. The weighing operation may be carried out while the articles are at a temperature above 500‹ C. and the movement of the table used to give an indication as to whether the article is too heavy or too light, for example by illuminating different coloured lamps, so that the supply of molten glass to the forming machine can be regulated. The support G and table I may be constituted by a number of closely arranged projections to reduce heat transference, and the conveyer B constructed of links with substantially flat tops and spaced, preferably in staggered relation, to provide air spaces. The conveyer may be actuated by a belt, driven by an electric motor through reduction gearing, and passing around an expanding pulley which can be adjusted to vary the speed. The motor gearing and pulley may be mounted on a hinged plate the combined weight of which keeps the belt tensioned.

IPC: H01J25/49
Filed: 1959-10-28
Abstract: 888,913. Space charge wave tubes. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 19, 1960 [Oct. 28, 1959], No. 36613/59. Class 39(1) A parametric amplifier with an input signal coupling section to make the electrons of the beam follow helical paths, an amplifying pump section with an axial magnetic field and a multiple quadrupole electrostatic field which increases the rotational electron energy and an output signal coupling section, successive quadrupole fields being so orientated that the changes in rotational velocity of the electrons are cumulative. The pump has four hyperbolic electrodes. Either (a) there is no axial bias, the beam slowing up as the rotational velocity is increased. All the positive pairs and all the negative pairs of electrodes are connected together and to external leads (b) axial bias, constant axial velocity and pitch of electrons, the rotational velocity increasing or (c) axial accelerating bias the rotational and axial velocities increasing. The quadrupole pitch increases to maintain synchronism. In Fig. 2 rings each having 2 tongues 6, 7 are piled up with intermediate insulating rings to form quadrupoles. Each conductive ring forms the high voltage pair of one quadrupole and the low voltage pair of the next quadrupole. The axial lengths of successive rings increase. Potentials are applied by a potential divider chain outside or inside the envelope. Insulating support rods fit in four locating holes 8, 9, 10, 11. In Fig. 3 the quadrupole electrodes have connections Vo-V 12  from the potential divider chain to reduce the number of connections and to give smaller voltage increments between the quadrupoles than in Fig. 2. Insulating support rods 18, 19, 20, 21 are provided. In general the quadrupole electrodes are “ of a cyclotron period long and in Fig. 2 successive quadrupoles are rotated by 90 degrees. The output is coupled to the fast or slow wave in the latter case it is a slow wave structure. An axial magnetic field focuses the beam and sets up the initial helical motion thereof. The pump structure may alternatively be a four start helix.
