Title: Sliding doors
IPC: E05F15/14
Filed: 1971-04-19
Abstract: 1351300 Multiple sliding door structure E M PETTERBORG 19 April 1971 [18 May 1970] 27095/71 Headings E1J and E2M A multiple sliding door structure includes a door panel support frame 5 and a door track 2 extending therefrom across a room. A plurality of separate door panels 37-41 are individually suspended from a door panel carriage 17 adopted to be driven transversely to the door track by a reversible electric motor 81 to successively effect planar alignment of each panel with the door track; and a drive means, e.g. friction wheels 104-117 operable by a motor 103, is operable to propel each panel from the panel carriage 17 along the track 2, or to reverse the procedure. The motors 81, 103 are actuable by automatic control means. The panel carriage 17 comprises several separate storage tracks 26-29 each carrying a separate panel by means of wheels and each having a slot 36 through which friction wheel 117 may engage the panel. The carriage 17 is driven by thrust members 93 threadedly engaged on spindles 86, 87 driven by the motor 81. The door track 2 comprises a section 49 rigidly attached to the ceiling D and sections 46-48 vertically movable by individual cord and pulley arrangements attached to levers 66, 72 76 in turn connected to cam levers 68-68", the movement of the latter being controlled by a cam disc 69 movable with the panel carriage 17. The friction wheels 116, 117 are pivoted by cords 123, 124 and solenoids 126, 127 to disengage them from the panels. The said control means comprises an electric circuit and a number of micro switches actuable by movement of the panels and panel carriage 17 which automatically actuate the motor 81 to move, in turn, each storage track 26 - 29 into alignment with the door track, switch off motor 81, move the respective panel along the track, lower the respective door track section 46 - 48 and panel until the panel touches the floor C and so on. Movement of the final panel actuates a switch to shut the motors down. The friction wheel 117 is automatically pivoted out of contact with the carriage 17 during transverse movement of the carriage. The door track section 49 is not lowerable and, to prevent there being a gap below the panel 41, the panel 39 tows behind it a track 142 which is straddled by a channel 146 on the panel 41. During return of the panels to the stored position, the track 142 is moved by a counterweight 171. Each friction wheel 104-117 has a friction clutch. (For Figures see next page)

Filed: 1956-09-07
Abstract: 813,858. Radio navigational beacons; aerials; valve oscillator and amplifier circuits; aerial couplings. SVENSKA AKTIEBOLAGET GAS, ACCUMULATOR. Sept. 7, 1956 [Oct. 3, 1955], No. 27462/56. Classes 40 (6) and 40 (7). A radio course beacon comprises a loop aerial one terminal of which is coupled to a highfrequency generator and the coupling capacitor between the other terminal and earth being so dimensioned as to be tuned, with half the loop, to the generator frequency. X 2  and R 2  are the loop reactance and resistance, (see Fig. 3), and it is demonstrated that to ensure that the potentials to earth of loop terminals A, B are equal and opposite, the capacitative admittance, Y 2 =2/X 2 ; and that to ensure resistive loading of output valve E capacitative admittance Y 1  equals Y 2  ; for propermatching a transformer link may be used and then Y 1  does not generally equal Y 2 . In the beacon described (see Fig. 8) mains A.C. is fed via transformer 30 to a push-pull crystal controlled oscillator which drives a push-pull power amplifier feeding a circuit which includes loop aerial 58 and a less directive loop aerial 59. The feed to loop 59 is phase reversed by coder 60 and may be attenuated via switch 62. Loop 58 is connected to the feed in accordance with the above principles. Capacitor 63 tunes in common both loops, capacitor 64 being disconnected when switch 62 is thrown. Loop 59 is always so loosely coupled to loop 58 by virtue of resistance in the former's feed path, that tuning of capacitors 66 and 67 is not affected by changes in the former's circuit. Capacitor 66 is permanently set to tune half of the inductance of loop 58 to the transmitter frequency. Variable capacitor 67 is used for setting course sharpness.

Title: Improvements in or relating to thermomagnetic starters for electric discharge tubes,in particular fluorescent lamps
IPC: H05B41/12
Filed: 1948-10-25
Abstract: 655,104. Supply systems for discharge tubes. EKKERS, G., FARNER, A., and FKG. F. KESSELRING GERATEBAU AKT.-GES. Oct. 25, 1948, No. 27747. [Class 38 (iv)] [Also in Group XXXVII] A starting switch for an electric discharge tube, e.g. a fluorescent lamp, comprises a magnet and contacts operable thereby when the permeability of a magnetizable member is altered due to heating by the starting current. In Fig. 1, contacts 11, 12 in the lamp-electrode heating circuit are normally held closed by a permanent magnet 10 acting on a magnetic spring member 9 carrying contact 11. When the main switch 2 is closed, the member 9 is heated by a current fed from the secondary 7 of a transformer 5, the primary 6 of which acts as a ballast impedance, and when the Curie point, preferably 200-300‹ C., of the member 9 is reached, it becomes de-magnetized and is released by the magnet 10, so that contacts 11, 12 open and cause starting of the lamp 3. The member 9 is kept de-magnetized by the normal operating current, and the contacts 11, 12 only reclose after switch 2 is opened. In a modification (not shown), the contact 11 is connected to the electrode 4 and is insulated from member 9 which is connected in series with the reactor 6 and switch 2. In Fig. 2, an auxiliary magnetic member 28 in series in the electrode circuit normally shields the contact carrying member 27 from the magnet 31, the contacts 29, 30 being normally held closed by the resilience of member 27. When the member 28 is heated above its Curie point it becomes de-magnetized and the magnet 31 attracts member 27 to open contacts 29, 30. In a modification (Fig. 3, not shown), the shielded main magnetic member comprises an armature mounted at the free end of a contact-carrying spring blade of e.g. German silver or bronze, the magnet being formed by an air-cored ballast reactor. In a further modification (Fig. 4,. not shown), the auxiliary magnetic member is omitted and the magnet holds the contacts closed, the armature being heated by a heating coil. Fig. 5 shows an arrangement wherein contacts 84, 91 are normally held open by a magnet 86 acting on an armature 89 carrying the contact 91. When the main switch 76 is closed, a glow discharge between armature 89 and an electrode 82 heats the armature which becomes de-magnetized so that contacts 84, 91 close the heating circuit. The glow is however short-circuited and, on cooling, the armature 89 is attracted by the magnet to re-open the contacts 84, 91. Modifications are also described wherein heater resistances are connected in circuit after the electrode circuit is opened, so as to maintain the armature de-magnetized (Figs. 6, 7, not shown).
