Title: Improvements in potentiometers
IPC: H01C10/32
Filed: 1958-04-30
Abstract: 856,843. Variable resistors. WELWYN ELECTRIC Ltd., [formerly WELWYN ELECTRICAL LABORATORIES Ltd.], and WHITFIELD, E. H. June 16, 1959 [April 30, 1958], No. 13781/58. Class 37 A mounting for an edge control potentiometer comprises a bracket 1 having two spaced lugs 7, each containing one of two parallel slots 8. At least one of the lugs is deformable, or displaceable, to permit the potentiometer to be inserted between the lugs such that the two slots engage with projections 11 on it In one embodiment a number of potentiometers 6 are mounted on a bracket 1 with a segment of their bodies projecting through slots provided in the base of the bracket The bracket may carry connection plates 16 at its ends and part 18 of the lugs 7 may be removed and the potentiometer inserted by twisting the end portion. In alternative forms, the bracket may be in the form of a U-section with the lugs separated on one side only (Fig. 6, not shown), flat (Fig. 7, not shown) or the sides of the U may be made of resilient material such that they are readily forced apart by insertion of the potentiometer (Fig. 8, not shown). In a modification of this last type (Fig. 9) a potentiometer 6 may be mounted such that one segment of it projects beyond the length of the bracket instead of through it by means of slots 38. In either of these last mentioned types of bracket, the sides of the U may be separated into separate lugs as shown by the dotted lines. Each potentiometer may have an arcuate resistance track mounted on a fixed part of the case, with the wiper connected to a rotatable drum forming the other part of the case. The lugs may be either formed on the fixed part, or may be a separate plate attached thereto.

Abstract: 625,902. Magnetrons. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 7, 1946, No. 13825. Convention date, March 22, 1945. [Class 39 (i)] [Also in Groups XL (b) and XL (c)] A magnetron comprises an anode block 10, Fig. 2, defining a plurality of cavity resonators, alternate anode segments are connected by straps 25, 26 and intermediate anode segments by straps 25<1>, 26<1>, and a tunable resonator is coupled to one of the straps 25 for varying the oscillation frequency. The tunable resonator is preferably a coaxial line 30, 31 tuned by either (a) a piston 38, (b) by varying the length of the inner conductor 31 by making it in two telescoping parts, Fig. 3 (not shown), (c) by varying a capacitance connected to the coaxial line, or (d) by tuning a cavity resonator coupled to the coaxial line. Power is taken out by a loop 21 forming an extension of the inner conductor 21<1> of a coaxial line, the outer conductor 22 of which is screw-threaded at 24 so that the coaxial line can be connected to an extension which may couple the' device to a radiator. The anode may be (a) a block with slots which may or may not be enlarged at their outer ends, or (b) vanes or slats supported by a conductive ring, In the former case the straps 25, 26 ; 25<1>, 26<1> are at opposite ends of the anode block. - In the latter case, ring strapping may be used, one conductor of the coaxial tuning line being coupled to one ring and the other conductor to the other ring. The tuning line and output line are preferably less than 90 degrees apart to suppress spurious modes. The device may be frequency modulated by means of a tunable coaxial line 40, 41 energized by a modulating circuit 42 and coupled to strap 26. Prior art arrangements for tuning resonators of magnetrons involving movable parts within the resonators or elsewhere within the envelope are referred to. Specification 588,916 is referred to.

Title: An improved device for the suspension and release of objects from aircraft
Inventor: HAYDON-SOUTAR WALTER HENRY
IPC: B64D1/06
Filed: 1959-04-24
Abstract: 871,089. Hooks. AERO CONTROLS Ltd. April 14, 1960 [April 24, 1959], No. 14071/59. Class 89(2). [Also in Group XXI] A device for suspending and dropping objects such as bombs and fuel tanks from aircraft comprises a housing 1 of light alloy containing linkage and a solenoid for moving a shaft 6 out of the housing so that steel lugs 3, pivoted on the shaft and held in engagement with a load by the pressure of a steel plate 8, are freed, and release the load. The lugs 3 pivot about a pin 4 passing through a part-spherical bush 5 and mounted in an eye end of the shaft 6, which shaft is guided by a bush 7 within the housing. The shaft is connected to toggle linkage 10, 13, 13a stressed by a spring 22 but held in the loadsupporting position by a toothed quadrant 15, which meshes with a quadrant 16. Quadrant 16 is urged to the release position by a spring 21, but is held cocked by the armature 19 of a solenoid 20. On energizing the solenoid or applying a pull to a lever 23, the armature moves and releases the quadrant 16, which then rotates quadrant 15. The pull on link 10 due to spring 22 and the load breaks the toggle and shaft 6 moves downwardly freeing the lugs 3 from plate 8. Link 10 as it rotates operates a micro-switch 27 to indicate audibly or visibly the release of the load. To attach the load, an eye on the load is pushed between the lugs forcing the shaft 6 upwardly to the position of Fig. 3, the switch 27 being closed to indicate that the unit is cocked. A sealing compound is introduced between the mating faces of the housing and the shaft 6 is sealed by an O-ring 9. A rubber collapsible sleeve 26 seals the spindle extension of the solenoid armature.

The position of bolts 7 in the bobbin transfer zone is variably adjustable but elsewhere in the runs of the chains their position is fixedly predetermined. As shown in Figs. 3 and 4, at the transfer station located near the deflection of the chain about guide roller 10, tensioning rollers 11 and 12 are movable in the directions H and G and roller 10 can be movable in direction H' and, thus, the position of bolt 7 contacting roller 10 may be altered in a range B along the circumference of the roller or within an area F without longitudinally displacing the chain. At the discharge end of the box, where chain 5 is deflected around wheel 8, packages are transferred by simultaneous actuation of pressure cylinders onto a trolley or a shipping creel, Fig. 5 (not shown). Two chains, as at 5, may be arranged above one another, Fig. 8 (not shown) and are driven synchronously as by means of driving and sprocket wheels adjustably clamped together so that the bolts 7 of both belts are uniformly aligned in all positions of the chains.

Abstract: 620,747. Electric selectors. DEHN, F. B. (Wurlitzer Co., R.). June 8, 1945, No. 14580. [Class 40 (iv)] An electric impulse actuated switch comprises a wiper arm 167 fixed to but insulated from a rotatable shaft 165 which also carries an insulated contact arm 168 wiping over a conducting segment 171. Energization of a magnet 153 rocks through its armature 173 a spring-biassed collar 174, rotatably mounted on the shaft 165, whereby a spring-biassed pawl 175 pivoted to the collar and normally held out of engagement with a ratchet-wheel 166 is rocked to advance the latter and the shaft 165 to which it is fixed, one step. A pin 180 on the collar 174 actuates switch contacts 157. The latching relay 163 upon energization rocks its armature 183 against its biassing spring 185, an extension 186 of 183 engaging a pin 187 on a locking pawl and forcing it into engagement with the ratchet-wheel 166 to prevent reverse rotation thereof. When the relay 163 is de-energized a further extension 190 of its armature 183 engages the pin 187 to lift the locking pawl 188 out of engagement with the ratchet-wheel 166 which with the shaft 165 and wiper arms is then returned to normal by a biassing spring 191.
