Title: Improved method and apparatus for handling wire
Inventor: JONES EDWARD OWEN
IPC: B65H49/08
Filed: 1958-04-11
Abstract: 873,907. Reel holders. CONNOLLYS (BLACKLEY) Ltd. Oct. 7, 1958 [April 11, 1958], No. 11621/58. Class 18. [Also in Group IX] In apparatus for handling wire (especially very fine ones), a reel 2, Fig. 1, having the ratio of the diameter of the barrel to that of the flange over which the wire is to be drawn off (e.g. the upper one 5, in a vertical arrangement) high enough to make it unnecessary to use a flyer, is mounted coaxially in a container 1 so that (a) the annular space between the container and the flange is sufficient to prevent the wire from ballooning when it is withdrawn through a guide above and on the axis of the reel, and (b) lateral movement between the container and the other flange (the lower one 4 in the form shown) is prevented. The ratio referred to for wire of 0À015 inch diameter may lie between 5 : 8 and 7 : 8, and in the case of tapered barrels the effective diameter of the barrel is the mean diameter thereof. The movement of the lower flange with respect to the container is prevented by shaping the container to fit the shaped edge of the flange or to provide a boss fitting into the hollow centre of the reel or into a recess in the lower face of the flange ; or a liner may be provided between the side-wall of the container and the reel. The container may have a bar 6 to serve as a handle. For transporting and storing the apparatus a lid 7 is secured by a clamp 9 and has a groove 8 between the upper flange and the container. The bottom of the container has an annular projection 10 ; such projections co-operate with the grooves 8 when adjacent containers are stacked for storing or transporting. In withdrawing the wire, the lid is removed and replaced by a cylindrical support 16, Fig. 5, having a guide 17 while a highly-polished steel ring 19 is placed over the upper flange.

Title: Improvements in microwave modulators and power dividers
IPC: H03C7/02
Filed: 1946-04-16
Abstract: 616,296. Wave-guides. WESTERN ELECTRIC CO., Inc. April 16, 1946, No. 11663. Convention date, April 26, 1945. [Class 40 (viii)] [Also in Group XL (c)] A wave-guide modulator or power divider for micro-waves comprises a principal waveguide adapted to propagate a linearly polarised carrier wave, means for converting the carrier wave into a circularly polarised wave, means for reflectively modulating the circularly polarised wave without reaction upon the carrier source and a branch guide for removing and separately propagating a linearly polarised modulated wave. In Fig. 1 a carrier wave source 4 applies to a main waveguide B a wave which is linearly polarised in the direction of the arrow Eo and so is unaffected by a septum 8 at right-angles to Eo. A conducting fin 1 arranged at 45 degrees to Eo resolves the wave into two vectors, one at right-angles to the fin, and one parallel to the fin. The length of the fin is chosen so as to retard the second vector 90 degrees in time phase to produce a circularly polarised wave. This wave encounters probes 3, 3<1> parallel to the constituent vectors and connected to modulating crystals in coaxial stubs 2, 2<1> supplied in parallel from a common modulating source. Variations in the crystal impedances due to variations in modulating voltage varv the amount of carrier-wave reflected back towards the source, the un-reflected energy being absorbed by a wooden cone 14. One vector of the reflected wave is retarded a further 90 degrees, thus converting the reflexted wave into one which is linearly polarised in a direction at right-angles to the original direction Eo. This wave cannot pass septum 8, and passes through slot 7 into a branch waveguide A to a load as a linearly polarised modulated wave E. The probes 3, 3<1> are placed one half wave-length apart to prevent interaction. In a modification, Fig. 2, (not shown), there are two opposite phase shifting fins, and four modulating probes arranged at right-angles in one plane. Fig. 3 shows the apparatus arranged as a power divider. The incident wave Eo after conversion by a pair of phase-shifting fins 10 is reflected by two pairs of modulating probes 3, 3<1>, and after conversion by fins 10, the reflected energy is taken off as a linearly polarised eave E through branch guide A. The remaining energy passes on through the main guide B where a second pair of phase shifting fins 11 converts the circularly polarised wave into a linearly polarised wave. The power ratio of the separable linearly polarised components depends on the voltage applied to the modulating crystals.

Title: Improvements in apparatus for the cleaning of objects by means of condensing vapour
IPC: C23G5/04
Filed: 1949-05-04
Abstract: <PICT:0679718/III/1> In open-topped apparatus for the vapour degreasing of articles, the apparatus is provided with a thermo-static regulator to keep the limiting stratum between the vapour and the air at a predetermined level in the container in which the cleaning takes place and so form a cold zone above this level for the purpose of condensing vapour which may be stirred up above this level, such as when the articles are lowered into or raised from the container.  The thermostat controls the opening or closing of an electric circuit including the heating members for the degreasing solvent.  In the form shown, the open-topped container 1, as more fully described in Specification 679,717, is provided at its lower part with two compartments, a heating compartment for vaporizing the solvent and a condenate receiving compartment for collecting the condensate from the walls of the container, a spill plate over the latter compartment directing dirty condensate from the articles into the heating compartment and a channel above and along the walls of the heating compartment directing the condensate from the walls into the condensate receiving compartment.  The electric heating means 11 in the heating compartment, having connections surrounded by a hood 12 on the outside of the container, is connected to the current supply system L1, L2, L3, through an electromagnet is relay 14.  The latter is controlled by a thermostat switch 21, having a feeler located in a pocket 24 in the front wall of the container at the predetermined vapour-air level, the relay 14 being opened and the heating means cut off when the vapour reaches the thermostat feeler, heating of which operates the relay 14 through the thermostatic switch 21.  On the vapour falling the thermostat feeler cools and operates the relay 14 to close the circuit and start the heating again.  The vapour level thus hunts between an upper and a lower limit.  The heating compartment is also provided with a feeler 161 connected to a thermostatic switch 16 which similarly controls the relay to prevent dry-boiling.  An electric motor may be provided in the supply circuit for driving a pump 29 for use in pumping clean solvent from the condensate receiving compartment to a nozzle 32 for flushing the articles being cleaned.  The cooling means at the top of the container preferably comprises a single cooling coil or at most two coils 33 with an inlet 35 and directly below, an outlet 36, the cooling water flowing when it is coldest firstly along the front wall of the container so as to obtain the most effective cooling where the risk of stirring up vapour is greatest on the side where the operator is standing.
