Abstract: 609,899. Thermal switches. MASKELL, A. E., and TEPPER, S. March 25, 1946, No. 9090. [Class 38 (v)] In an electric iron embodying a thermal switch, a flexible strip 14a connected to one end of the heating element 2, carries at 16 an S-shaped member 17 having a contact 18 eiigageable with a rigid contact-blade 14, which is connected by means of a bridge-piece 21 to a terminal 19, the other terminal being connected to the other end of the element 2. The member 17 seats on arm 12, pivoted at 13 and engaged by a rod 9 carried by an operating lever 8, pivoted at 7 within a longitudinal-slot in a handle 6. When the lever 8 is depressed it tilts the arm 12, allowing the contact 18 to engage the blade 14 and close the circuit. At a predetermined temperature, a bimetal strip 15a secured to the base at 15, flexes upwards, lifting the member 17 away from its seat on the arm 12 and separating the contact 18 and blade 14 notwithstanding the lever 8 being in switch-closing position. The operating temperature of the iron is adjustable by a cam 20 engageable with the arm 14. A pilot lamp may be fitted to the handle.

Title: Improvements in or relating to mechanism for converting angular movement into axialmovement
Inventor: COLLARD JOHN
IPC: H01J25/24
Filed: 1953-04-01
Abstract: 760,323. Velocity-modulated tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd. March 18, 1954 [April 1, 1953], No. 9119/53. Class 39(1). [Also in Group XXIV] A spring-loaded cam mechanism for converting an angular or rotary movement into a small axial movement is shown applied to a tuning mechanism for moving the wall of a klystrontype resonator, and comprises a fixed element 10 having a conical surface opposing a spirallygrooved element 9 which is rotatable on an axially-movable sleeve 8, one or more balls or other followers being interposed between the elements so that rotation of the element 9 causes movement of the followers along the spiral groove, their consequent radial movement over the fixed conical surface causing axial movement of the element 9. The axial movement is conveyed through a thrust bearing to the non-rotatable sleeve 8 which is fixed to a sleeve 7 coupled to the movable resonator wall (not shown). The mechanism may be axially loaded by a plurality of springs 16 interposed between a cooling fin on the sleeve 7 and a fixed bracket 3, or alternatively by a central disc or other spring. The element 9 may be rotated by a cap 17 or by gearing. The spiral groove is preferably of arcuate section to receive the ball followers. If the groove is flatbottomed the followers may be frustro-conical. Where three followers are provided they are held in equidistantly-spaced radial slots in a cage and preferably co-operate with three separate spiral grooves. If three followers are employed with a single spiral groove they may be of different diameters to prevent tilting. The limits of rotation are defined by pins in the ends of the grooves. It is stated that the conical surface may be replaced by a curvilinear or other surface, that the grooves may be other than true spirals, and that the grooves may be formed on the conical surface. The mechanism may be employed in a lifting device or a press. According to the Provisional Specification a conical-surface element similar to the element 10 is axially moved by rotation of a spirallygrooved element similar to the element 9.

Title: Improvements in and relating to bogies for vehicles
IPC: B61F5/08
Filed: 1938-03-28
Abstract: 512,997. Railway vehicle bogies. SPENCER MOULTON & CO., Ltd., G., and GLASCODINE, R. T. March 28, 1938, Nos. 9440 and 36996. [Class 103 (vi)] In a vehicle bogie lateral movement of the' bolster 2 relative to the bogie frame 1 is resisted by a spring gear which imposes a progressively increasing resistance to the lateral movement whilst permitting free vertical movement, the springs co-operating with rocking levers having cam contact surfaces whereby the mechanical advantage is continuously varied. As shown each of the springs 14, which are the compound rubber and metal plate type, is supported between an inner rocking plate 16 working upon the side frame 1 and and outer follower plate 15, 'against which bears the head of a rod 12 that passes through the spring 14 and frame 1 to engage a gudgeon pin 7. The latter pin is slidable in slots 10 in brackets 8 and is also engaged by a pair of levers 6, each of which is fitted at its free end with a roller 5 adapted to contact the vertical face 4 of the bolster 2. Lateral movement of the bolster causes cam surfaces 22 on the levers 6 to work upon the inner faces of the frame 1, moving the pins 7 inwardly along the slots 10, and causing the rods 12 to compress the springs 14, which at the same time exert their effort about a gradually increasing lever arm. The movement may further be damped by the provision of single or double-acting dashpots 25, 26, which are operated by means of lugs 29, 30 on the plates 15 through the medium of pins 31, 32 and interconnected pivoted links 33, 34, 35, 36. Specification 390,555 is referred to.

Filed: 1974-03-05
Abstract: 1434664 Film cartridges SUNDSTRAND DATA CONTROL Inc 5 March 1974 [5 March 1973] 9731/74 Heading B8M In a cartridge wherein an endless loop of film follows a guide path extending from the inner convolution of a rotatably supported planar roll, over the face thereof, past a film projector station and then returns to the outer convolution of the roll, the path across the roll comprises an inverted channel defined by opposed side walls which are smooth, inclined to one another and may be internally concave so as to engage the upper edge of the film without engaging (and possibly abrading and/or scratching) opposite surfaces thereof. In the operation of the cartridge shown, a motordriven turntable 17 housed in a cylindrical compartment rotates a roll 20 of film 21 which is compelled to advance through a guide channel 32 into a rectangular compartment housing projection apparatus. The channel 32 has a cross-section throughout its length formed by a flat top 54 and side walls 90, 91. When film 21 begins to emerge from the inner convolution of roll 20 at a transverse rib 58, it moves into entry portion 33 of channel 32, through a transition section 84, then rides over a series of U-shaped clips, as at 48, 49, which hold the lower edge of film 21 in position in the upper level of the channel extending above the film roll. Film passes into a variable length compliance loop 60, defined by rolls 70, 72, 74, 76, supported by ribs 78, 80, 82, and confined by the outer wall of a chamber (62) around guide pin 36 and roller 42 before being directed past guide pin 56 to form the outer convolution 35 of the roll 20. The intermittent advancement of the film past projection aperture (39) as effected by conventional claw mechanism is isolated from the movement from roll 20 by the loop 60. Turntable 17 comprises radial steel wires 24 which support roll 20 with minimum resistance to its movement. The inner convolution(s) of the roll are isolated from looseness migrating radially inwardly through the roll, as by a roll separator 96.

Title: Improvements in or relating to the control of rotating wing aircraft
IPC: B64C27/54
Filed: 1944-05-22
Abstract: 576,876. Rotary wing aircraft. FAIREY AVIATION CO., Ltd., and HODSON, C. F. May 22, 1944, No. 9833. [Class 4] The simultaneous and cyclical pitch variations of. the blades of a rotary-wing aircraft are effected by vertical and universal movements respectively of a member connected by arms extending integrally therefrom in planes substantially at right angles to one another with two further vertically movable rods, the members being operatively connected with the inching valves of hydraulic jacks by which the blade movements are controlled. In the form illustrated, the blades a are connected by supporting links c which engage through springs k, m, a rod d mounted for universal movement about the upper end e of a vertical rod f, the lower end of the rod d carrying a radical arm q connected by a link s to a vertical rod u, and a second radial arm perpendicular to the arm q which is connected to a further vertical rod v. The lower end of the rod f is connected to the inching valve w of a hydraulic jack x arranged to raise and lower a spherical bearing y of the swashplate z to effect simultaneous blade pitch variations. Cyclical pitch variations are effected by a jack 16 operated by an inching valve 15 connected to the lower end of the rod u 'and by a similar jack and valve connected to the rod v. Equal flapping movement of opposite blades results in vertical movement of the members d, f, with consequent simultaneous variation of pitch, while unequal movement causes tilting movement of the member d about the universal joint e to produce a cyclical pitch variation. The inching valves are connected by rods 24, 26, to the pilot's control mechanism.
