Title: Improvements in or relating to electron discharge devices
IPC: H01J25/24
Filed: 1945-10-19
Abstract: 629,238. Velocity-modulated tubes. PHILCO CORPORATION. Oct. 19, 1945, No. 27610. Convention date, Aug. 31, 1944. [Class 39 (i)] [Also in Group XL (c)] A velocity modulation electron discharge device for use in a frequency multiplying circuit comprises a resonant cavity, a repeller electrode, and a control grid, the repeller electrode being at a potential intermediate that of the cathode and the cavity so that the arrangement-is not self-oscillating, and the frequency of the resonant cavity is a multiple of the input frequency which is applied to the grid. The figure shows a " Klystron " (Registered Trade Mark) tube and a source 19 of radio frequency which is applied through a tuned transmission line between the control grid 14 and the cathode. Alternatively, an external band 18 may be used in place of the cathode for this purpose. The potential of the repeller electrode 15 is adjusted by means of a voltage divider 31 to a value intermediate that of the cathode and resonator 17 so as to introduce feedback and increase the output at harmonic frequency in resonator 17, although in the absence of the input to the grid, no oscillations are produced. The source 19 may be frequency-modulated by modulator 33. The frequency deviation of the output is limited by the Q of the resonant cavity 17, which may be controlled by resistive loading. Specification 582,526 is referred to.

Title: Improvements in sliding bolts for securing wire blinds, and for doors and for other like uses
IPC: E05C1/04
Filed: 1920-09-30
Abstract: 172,459. Smith & Davis, Ltd., and Smith, H. F. Sept. 30, 1920. Sliding bolts.-A bolt 9 for securing the tops of wire blinds &c. slides on a base-plate 1 by means of a headed rivet 7 rigidly fixed to the bolt and working in a slot 5 in a pressed-up part of the base-plate. Alternatively the rivet may be fixed to the base-plate and the slot cut in the bolt. The bolt is operated by a finger-piece 11, and the length of the bolt is such that when it is withdrawn its end may be sprung out of the hole in the upturned end 2 of the baseplate and turned about the axis of the rivet 7, as shown, to give access to the securing screwholes 4. The head of the rivet may be flattened so that by turning the bolt at right-angles to the base-palte, it may be removed, the head passing through the slot. If desired, the head may be circular, allowing the bolt to be turned for securing or removing the base-plate, but preventing its removal. A spring 15 may be fixed between the bolt and the base-plate by means of the rivet, to hold the bolt in its slot or withdrawn position.

Patent GB-837829-A (GB)
Title: Improvements in or relating to resuscitators
Inventor: ISAACSON MAX
IPC: A61M16/20
Filed: 1957-09-03
Abstract: 837,829. Respiratory appliances. GLOBE INDUSTRIES Inc. Sept. 3, 1957, No. 27830/57. Class 81 (2). An apparatus for inducing forced respiration comprises a pressure-actuated valve which automatically opens and closes the outlet from an ejector assembly, the valve being located in the opening through which the aspirator communicates with a chamber connected with the lungs. Air or oxygen is blown in through a tube 24, which encloses a nozzle directing a jet into an outlet tube 26 leading to atmosphere, so that air may be drawn out from the chamber 22 through the opening 30. This chamber 22 is connected through a duct, not shown, to the patient's lungs and thus the pressures in the lungs and in the chamber are the same. A flexible strip 46, pivoted on a screw 100, may be lowered into the position shown, so as to obstruct and seal the passage into the tube 26, as a result of which air, continuing to enter through the tube 24, is retained in the chamber 22 and lungs, increasing the pressure therein. Actuation of the valve is performed by a diaphragm 48, forming one wall of the chamber 22 and increasing pressure therein first compresses the upper spring 58 and then, through a collar 60, raises a rod 54 at the top of which an armature 62 tends to be held by a ring magnet 68. When the pressure is sufficient to overcome the magnetic attraction, the rod springs upwards and is then retained by a similar magnet system at its lower end, at the same time raising the valve member 46 by means of a cross-piece 80. The extractor effect of the jet in the tube 24 now withdraws air from the lungs and chamber 22 until the pressure is sufficiently reduced for the diaphragm 48 to move the rod 54 in the opposite direction again. This inhalation and exhalation cycle is consequently repeated indefinitely. The limiting pressures causing changeover may be adjusted by rotating the rod 54 and its armatures 62 by means of a cover 72 since this displaces the armatures in relation to the diametrically placed poles of the ring magnet 68 and thus the effective pull of the magnets is correspondingly reduced.

IPC: H05H1/34
Filed: 1969-06-03
Abstract: 1276930 Plasma apparatus N A CHESNOKOV G P STELMAKH A S SAKHIEV and N N RYKALIN 3 June 1969 28005/69 Heading H5H Plasma apparatus, for effecting chemical or physical transformations of materials in particulate, gaseous or liquid form, comprises a plasma torch 1 mounted so that a plasma jet 2 therefrom coincides with the axis of an annular cross-section anode 3 or 11 and serves as a non- eroding cathode for producing a distributed discharge region 6 within a magnetic field, e.g. of a solenoid magnet 5. The anode is a cylinder 3, or a conical spiral 11, or a cone 9, Fig. 2 (not shown), and the discharge fills the region 6 within the anode. A device 7 for feeding in a cold quenching gas is provided beyond the region 6. A triggering device 28 initiates a discharge between the cathode 16 of torch 1 and an auxiliary anode 19 for ionizing the gas passed through the cooled insulated sections 21 of the torch. Power from a source 13 applied to torch anode 18 then results in generation of the plasma jet 2 to serve as gas cathode for the diffuse or glow discharge in region 6. Prior to triggering the apparatus is evacuated and then a plasma-generating gas at 10 mm. pressure is fed in. When the discharge is established in region 6, the materials to be processed are fed in via tube 30. The electromagnet 5 is energized from a separate power source 27, or from source 13 for torch 1, or from power source 25 for generating the discharge of region 6, source 25 being a D.C. or A.C. generator. Current connection from source 25 to the gas cathode 2 is via the torch anode 18 or via a separate contact ring 24, Fig. 4 (not shown). The conical spiral anode 11 is non-magnetic and co-operates with the cooled magnetic casing 12 to provide the magnetic field for region 6. This embodiment operates at higher pressures, the diffuse discharge pinching to form an arc between the base of cathode 2 (anode 18 of torch 1) and a turn of the anode 11, the arc rotating and travelling along the anode towards its converging end. Additional shunting arcs arise simultaneously on the other turns of the spiral, travelling in a similar manner to the first arc and thus filling the region 6 with a plasma discharge. The torch 1 of Fig. 3 differs from that of Figs. 1, 2, by having a dielectric interelectrode insert 21<SP>1</SP>.

Abstract: 1,151,353. Welding by pressure. ROLLSROYCE Ltd. 1 July, 1966 [2 July, 1965], No. 28163/65. Heading B3R. Resistance welding apparatus comprises means for pressing together a pair of workpiece parts, the means including a member which has a surface for pressing on one of the parts, the member having a hole extending through it from a position at or adjacent to the surface, and the apparatus further comprises a sensing means to sense radiation passing along the hole from the said position to provide information as to the effectiveness of the weld. A resistance welding machine has a pair of rod-shaped electrodes 1, 2 with circular end faces 3, 4 engaging sheet metal components 5, 6, the copper electrode 2 having a hole 8 at one end opening in the face 4 and extending right through the electrode to be open to an infra-red sensing device 9. The device 9 is connected to a means for giving a signal if the temperature of the workpiece is too hot or too cold. The output of the sensor may be used to provide a signal for automatically varying the welding current and/or duration of the current. The setting of the machine may be varied during the making of the welding if the weld is too cold. The hole need not break through the surface 4 when the heat sensed is that at the tip of the electrode. In a modification, the end of the electrode remote from the working end is threaded into a metal block having inlet and outlet passages and copper sleeves extending into the bore of the electrode. A photo-electric cell is carried at the far end of the bore and the electrode is cooled by water fed through the passages and around the sleeves and the cell may be included in a control system as described above. Alternatively, the sensor is focused through a mirror on to the point on the component. Both electrodes may be associated with heat sensors.
