IPC: F23M7/00
Filed: 1929-12-03
Abstract: 340,730. Furnace doors. HIRSCH, KUPFER-UND MESSINGWERKE, AKT.- GES., Messingwerk, near Eberswalde, Germany. Dec. 3, 1929, No. 37043. Convention date, March 11. [Class 51 (ii).] In furnace doors operated by electric motors means under the control of electromagnets are provided for pressing the door against its seat when the operating motor is switched off, the electromagnets being energized through the motor switch. The charging opening of an electric annealing or like furnace is closed by a door 3 suspended by wires 4 and raised and lowered by an electric motor 5. Doublearmed levers are pivoted at 9 on each side of the furnace, the short arms 6 being normally pressed against the door by weights 8 on the long arms 7. The end of each long arm 7 is connected with the armature 10 of an electromagnet 11 secured to the furnace wall and the magnets are connected to the switch of the motor 5 so that when the motor is started the magnets are energized and raise the arms 7, releasing the door. Pins 12 limit the downward movement of the arms 7 when the magnet is de-energized with the door in the raised position.

Title: Improvements in or relating to magnetron tubes suitable for use on ultra-short waves
IPC: H01J25/52
Filed: 1938-12-20
Abstract: 522,905. Magnetrons. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Dec. 20, 1938, No. 37050. Convention date, Dec. 20, 1937. [Class 39 (i)] A magnetron tube for ultra short wave work comprises a strip-shaped Lecher line L located wholly or partly inside the envelope, and a number of straight-edged anode plates S1, S2, S3, S4, arranged transversely to the length of the line and perpendicularly to and between its planes ; they are arranged radially to a cathode K so that the cathode and their inner edges constitute a discharge system, the anodes being fixed in groups S1, S3 and S2, S4 to the two sides of the Lecher line and being less in height than the distance between these two sides. The Lecher line is carried at the midpoint by a support S, and the cathode by support leads H. Further to increase the mechanical stability of the device the anode plates may be formed integrally in pairs by bending over the arch of a flat U-shaped plate, this portion being used to secure them to the Lecher conductor. The Lecher conductor may be channel shaped in cross section. To prevent too great a capacity between each anode plate and the oppsiote side of the Lecher line the edge of the plate next to that side is tapered away from the active edge next to the cathode so that the gap between plate and Lecher conductor is not parallel-sided. The plates are preferably mounted diagonally as shown. Interception plates carried by the support 5 or a negatively biassed strip on the envelope may be used to prevent electron bombardment of the envelope.

Title: Devices comprising braked rope drums for lowering persons or loads
IPC: B65H75/44
Filed: 1974-08-27
Abstract: 1480958 Hydrodynamic brakes; hydraulic dampers SISARAKENNETEOLLISUUS OY SIRATE AB 27 Aug 1974 [7 Sept 1973] 37339/74 Headings F2E and F2S [Also in Division B8] A device 10 which a workman can use as a safety device comprises a housing 12 having a ring 90 for attaching the device 10 to an anchorage on a building, a rope drum 14 being rotatably mounted on a non-rotatable shaft 16, the rope 17 having a hook (92) at its free end for attachment to the workman's safety belt, Fig. 2 (not shown), the device 10 also including a braking device 20 which is operative to brake the drum 14 if the workman falls and thereby causes the drum 14 to rotate rapidly. The device 20 comprises a brake cylinder 21 filled with oil and having end plates 80, 82 at its ends, each plate having an undulating surface (80A, 82A) respectively), Fig. 3 (not shown), a pair of pistons 42, 44 being non-rotatably but axially-movably mounted on the shaft 16 on either side of a disc 40 which is rotatably but non-axially movably mounted on shaft 16, the disc 40 and pistons 42, 44 having undulating surfaces, as shown in Fig. 3 (not shown). The cylinder 21 together with its end plates 80, 82 is rotatable relative to the shaft 16, the disc 40 being pinned to the end plates. If the drum 14 is caused to rotate rapidly a pair of pawl members (64) pivotally mounted thereon are caused, by centrifugal force, to engage a ratchet ring (66) located on a part 21B of the cylinder 21, Fig. 2 (not shown), thereby causing the rotation of the cylinder 21, its end plates 80, 82 and the disc 40 along with the drum 14, relative to the shaft 16. The non-rotatably mounted pistons 42, 44 abut alternately the associated undulating surface (82A or 80A) of the nearest rotating end plate and the nearest undulating surface of the rotating disc 40 so that the said pistons are driven to-and-fro along the shaft 16, but due to slight clearances between the peripheral surfaces of the pistons and the surface of the cylinder 21 there is a high degree of resistance to the flow of oil from one side to the other side of each piston thereby giving rise to a braking effect on the cylinder 21 and thus to the rope drum 14. A spiral spring 70, which is attached at 48 to the shaft 16 and at 71 to the drum 14, causes re-winding of the drum 14 after the load has been removed from the rope 17.

Title: Radiation flux measuring device
IPC: G01T3/00
Filed: 1974-08-29
Abstract: 1460997 Radiation measurement: voltage measuring GENERAL ATOM CO 29 Aug 1974 [31 Aug1973] 37803/74 Headings G1A and G1U [ Also in Division G4] Radiation measuring apparatus comprises: a radiation detector for providing a signal having an A.C. component representing radiation flux; an attenuator with means coupling it to the detector output; a feedback circuit for maintaining the detector output constant; and means coupled to the attenuator for deriving a signal representing the logarithm of the A.C. component.  At high radiation flux rates, where simple techniques for counting pulses may not provide the necessary resolution, the r.m.s. value of the A.C. component produced by statistical fluctuations in - a detector output may be used as a measure of the flux rate. A fission chamber 111 comprising a pair of D.C. biased plates coated with U235 responds to an incident thermal neutron by producing two high-energy fission fragments which, by leaving an ionized track, enable a pulse of current to flow between the electrodes. The A.C. component of a train of pulses, amplified at 115, passes through a bandpass filter 121 to a controllable attenuator 113 effectively comprising, for A.C. signals, a parallel pair of matched resistors 135, 137 fed by a resistor 133. The attenuator output, after amplification at 123, is fed to a square-function generator 125 and integrator 127 producing a D.C. signal proportional to the r.m.s. amplitude of the A.C. component. The difference between the D.C. signal and a reference signal 131 is amplified at 129, 139 and applied to control the resistances of 135, 137, whereby they assume a value inversely proportional to the A.C. component. The resistors 135, 137, being effectively in series with a D.C. source 141, supply an input current, proportional to the A.C. component, to a logarithmic amplifier 143 which provides, via a further amplifier 119, the apparatus output signal. The amplifer 143 provides additional feedback to the amplifier 139 which renders the apparatus response time independent of the signal level. An alternative attenuator, Fig. 4, comprises an input transistor 249 having its collector coupled to the common emitter of a pair of transistors 245, 271, of which 271 has a collector load 253 providing the A.C. output V o . The D.C. control voltage required at the feedback terminal 255 to maintain a given current distribution between the transistors 245, 247, is a logarithmic function of that current distribution. Thus, when the feedback is arranged to maintain the r.m.s. output signal V o  constant, the control voltage V dc  is itself a logarithmic function of the r.m.s. input signal V in  on terminal 257.
