Filed: 1937-08-11
Abstract: 493,389. Moving signs. PAGE DISPLAYS, Inc. Aug. 11, 1937, No. 22096. Convention date, Sept. 24, 1936. [Class 3 (i)] A plurality of independent display bands, each carried on a spring roller, are circulated around a closed path, and are extended for viewing each as it reaches a window. The rollers 31 are mounted on brackets 33, the pintle entering a boss 34 and a cross-bar 40 at the free end of the band lying in a notch 39. The brackets 33 have slots which ride over a rail 60, and the cross-bars 40 have end-slots which engage an outer parallel rail 61. Two continuously moving parallel chains 24 carry each a freely hanging hook 26, the rear of which bears against a track 62 which is shaped so as to allow the hooks at certain parts of their path to fall back and at other parts to force the hooks forward to engage projections on the cross-bar 40 and/or the bracket bosses 34. The bend at 62c presses the hooks out to take under the bracket carrying the roller the band of which has just been displayed and under the cross-bar 40 of the following band. The displayed band is thus rolled up, and the following band gradually unrolled, the roller of the following band being retained by coaxial notched discs 18 rotated slowly by gearing. A bend 62D allows the hooks 26 to recede from the cross-bar 40 of the newly-displayed sheet and leave it held by springs 70, while the hooks carry the preceding roller around the track till it lies on the remaining rollers piled on one another, the track 62 bending away at 62F to permit the hooks to fall back. Rails 80 round the bottom keep the hooks 26 off the brackets in that region, and tensioning springs 82 extending from these rails bear against the chains 24. The cross-bar 40 is built up of two parts, one of which is resilient and is attached to the band free edge, and the other of which has a perforated projection entering a central hole in the first part and held therein by a staple, the two parts thus having a pivotal connection with one another which allows the band to adjust itself in winding on and off its roller.

Title: Improvements in and relating to the transmission of electrical energy between alternating current networks of different frequencies
IPC: H02M5/42
Filed: 1932-08-10
Abstract: 389,722. Frequency changing. AKT.- GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Aug. 10, 1932, No. 22421. Convention date, Aug. 10, 1931. [Class 38 (ii).] Three phase networks N1, N2, Fig. 1, are interconnected by means of a frequency changer which consists of two groups of rectifiers G1<SP>1>, G 1<SP>11> and G2<SP>1>, G2<SP>11>, connected by transformers T1, T2 to the networks, the secondary star points and cathodes in each group being cross-connected. Rectifiers G1<SP>1>, G2<SP>11> have control grids which are supplied with potentials in phase opposition to the potentials produced at the corresponding anodes by the associated network. When power is being transmitted from N1 to N2, rectifiers G1<SP>1> and G2<SP>1> do not function but rectified A.C. is supplied by C1<SP>11> to G2<SP>11> which acts as an inverter and feeds three-phase A.C: to the' network N2. Similarly when power flows from N2 to N1 the current flow is through rectifiers G2<SP>1> and G1<SP>1>. In a modification, rectifiers G1<SP>1>, G2<SP>11> -are replaced by a single rectifier having twelve anodes and control grids and rectifiers G1<SP>11>, G2<SP>1> by a single rectifier-having twelve anodes. The Specification as open to inspection under Sect. 91 comprises also the modification, shown in Fig. 3 (Cancelled), in which, associated with the networks N1, N2 are rectifiers G1, G2 having control grids, the energization of which are controlled' by a synchroscope S connected between the networks. When the condition of the networks is such that power should flow from N1 to N2 the synchroscope S opens the switch A and closes B ; rectifier A.C. is supplied by G1 to G2 which acts as an inverter and feeds A.C. to the network N2. Similarly when power flows from N 2 to N1 rectifier G2 is decontrolled and G1 is controlled. This subject-matter does not appear in the Specification as accepted.

Title: Method of and apparatus for the generation of foam for fire extinction
IPC: B01F5/04
Filed: 1934-08-01
Abstract: 442,372. Making foam. REED, H. V., 199, Lathom Road, East Ham, London. Aug. 1, 1934, No. 22424. [Class 47 (ii)] A method of making air foam consists in cutting up a water jet into piston-like portions which, in their passage through piston cylinders or spaces, draw charges of air into the spaces and sweep out of the spaces air previously induced into them, the charges of water and air being delivered to separate parts of a mixing chamber. Foaming agent may be added to the water jet or be induced into the spaces. As shown, a casing 1, with a water nozzle 9 perpendicular to its rear plate 4, houses a runner comprising inner and outer shrouds 7, 6 and blades 8 defining the piston cylinders or spaces. Preferably, the blades are helical and inclined to the axis of the runner, the developed shape of the blades being straight, Fig. 4. Alternatively, the blades may be parallel to the axis of the runner, and the nozzle inclined. The impact of the water jet on the blades causes the runner to rotate, successive pistons being cut from the jet. Inlets 10, 11 for air and foaming agent are provided in the plate 4, and outlets 14, 15 for the water and air respectively are provided in the rear plate 5. These outlets discharge into a mixing tube 16 and are separated by a wire mesh or like screen 17. The blades, inlets, and outlets are so arranged that the spaces register with the outlet 15 only after they have registered with the inlets 10, 11, so that successive pistons cut off at 9 sweep out the air at the outlet 15, the pistons being discharged at 14. The crosssection of the tube 16 may be varied, but the cross-sectional area of the air space therein should diminish towards the discharge end 18. Preferably, baffles are arranged above the screen 17 to cause the water to spread over the surface of the screen. The latter may be conical in form. In a modification, the water is delivered tangentially to a baffled mixing chamber within which is a cylindrical screen into which the air is delivered. The mixing chamber may be connected to the outlets 14, 15 by flexible tubes.
