Title: Indexing apparatus
IPC: B23Q16/02
Filed: 1973-01-09
Abstract: 1411001 Gearing; stopping machines at definite positions; positive detents; cams CYCLO INDEX CORP 9 Jan 1973 [10 Jan 1972] 1237/73 Headings F2Q F2E and F2K An indexing mechanism, for rotation of a dial plate 12 to an indexed position and for holding the plate in this position has a gear 56 which rotates with the plate 12 and which has facial teeth which mterengage with teeth on a gear 59, fixed to a fixed housing 51 by leaf springs 62 (Fig. 3) against rotation but movable axially by camming rollers 71 which engage with camming surfaces to move the gear 59 to engage and hold the gear 56. The rollers 71 are rotatably mounted at the periphery of a rotatable disk 69, limited rotation of this disk by a rod 74 causing the movement of gear 59. The rod 74 is moved by a cam 24 via levers 98 and 88, this cam being rotated by an output shaft 21 from a device 18 which has an input shaft 19, the device 18 also imparting intermittent motion to a further output shaft (22), (Fig. 2, not shown), (via a Geneva drive mechanism, not shown) which output shaft intermittently rotates the plate 12 by means of a worm 42 engaging teeth on a shaft 25 to which are attached plate 12 and gear 56. The shaft 21 driving the cam 24 may rotate continuously or intermittently and the system is arranged so that the cam 24 disengages the gear 59 from the gear 56 before an indexing movement and re-engages them after this movement.

Title: Improvements relating to electricity meters
IPC: G01R11/40
Filed: 1922-01-14
Abstract: 195,196. Chamberlain & Hookham, Ltd., and James, S. Jan. 14, 1922. Special quantities, registering.-An electricity meter comprises a pair of meters, of which one measures energy and the second the wattless component with means for producing movement of an integrating-device proportional to the vector sum of these components, the meter reading volt-ampere-hours. As shown in elevation in Fig. 2 and in plan in Fig. 3, a counting-train f is operated by an arbor around which revolves a planet pinion i driven by a pair of independently rotatable sun pinions g, h. The pinion g is driven continuously by an energy meter l. The pinion h is driven from a wattlesscomponent meter r through a pinion q, a vertically-moving rack p, and a cord o passing over a drum n and attached to a weight 5. The drum n drives the pinion h through a one-way clutch and gearing v. The rack p is periodically disconnected from the pinion q by an electromagnet x, the rack then falling to the position shown in full lines, in which the cord is horizontal. A contact y on a disc z rotated by the meter l makes contact once in each revolution between light springs 2 and thereby energizes the magnet x. The mechanism is so arranged that if the horizontal length o of the cord represents energy, the rise of the rack p during one revolution of the disc z represents the wattless component. The length of the cord o in the dotted-line position therefore represents the vector sum of these quantities, i.e. volt-amperehours. The drum n is rotated by an amount equal to the difference of the lengths of the cord o in the dotted and full-line positions, i.e. by an amount proportional to the difference between the volt-ampere-hours and the energy. The epicyclic gear g, h, i adds to this the motion proportional to the energy derived from the meter l, thereby causing the counting-train to register volt-amperehours. Instead of the rack and pinion a cord driven by the meter r may be used, also a rack may be employed instead of a cord to connect the epicyclic gear with the rectilinearly moving member. Mechanical or other devices may replace the electromagnetic device for periodically releasing the sliding member. The member p may move horizontally instead of vertically, the rightangle relationship to the cord o being maintained. This arrangement is preferable if the meter is to be used for both leading and lagging currents.

Title: Improvements in or relating to roll film photographic cameras
IPC: G03B19/04
Filed: 1942-02-03
Abstract: 548,754. Roll-film cameras. KODAK, Ltd. Feb. 3, 1942, No. 1439. Convention date, Feb. 10, 1941. [Class 98 (i)] A roll-film camera having means for simultaneously winding the film and setting the shutter and a mechanism which latches the shutter release against actuation until unlatched by the film winding operation, includes means for manually operating the shutter-setting means and for releasing the latch independently of the film-winding mechanism. The invention applies particularly to cameras having an adaptor back for art-films, during the use of which the filmwinding mechanism is not employed. The invention is illustrated as applied to the rollfilm camera having the same mechanism as that described in Specification 543,450, and described in the Specification, for simultaneously setting the shutter and winding the film and for interlocking the film-winding means and shutter release. In this mechanism a lever 20 pivoted at 21 is swung counter-clockwise to set the shutter by the movement to the right of a slidable frame 24, this movement being produced by contact with the frame of a roller 43 on an arm 42 which is rotated when the film is wound. To set the shutter independently, a lever 73 extending to the outside of the camera is moved clockwise to the position shown, an arm 77 on it contacting with a pin 78 on a slide 70 connected by a pin 71a to the slide 24, which is thus moved to the right to set the shutter. At the same time, a cam projection 80 on an arm 76 of the lever 73 engages a pin 79 on the interlocking lever 54, which is thus rocked about its pivot 55 to free the lug 53 from the slot 50 in the disc 49 and then moved to the right so that its end 62 moves the spring 63 from engagement in a groove in the shutter release member 28, which is thus free to be operated. Specification 549,195 also is referred to.

Patent GB-1027011-A (GB)
Title: Helicopter rotor
IPC: B64C27/54
Filed: 1963-01-15
Abstract: 1,027,011. Helicopter rotors. LOCKHEED AIRCRAFT CORPORATION. Jan. 15, 1963 [Jan. 22, 1962], No. 1736/63. Headings B7G and B7W. A helicopter has a rigid rotor, i.e. with blades pivotable about a feathering axis only, a rotor control gyro adapted to rotate in a plane parallel to that of the rotor, and adapted to change the incidence of the blades when the said two planes of rotation are displaced out; of parallelism, and a resilient link between the pilot control and the control gyro. The control gyro comprises a swashplate 35 to which are fixed arms 40, 41, 42 having at their ends masses 45, 46, 47 shaped to provide aerodynamic lift. A link 32 connects each blade 10, 11, 12 to the swashplate, the angular position of the link being about 60 degrees ahead of the blade feather axis. Cyclic control is effected by two rods 66 connected through springs 60, 70 (Fig. 3, not shown) to the cyclic control stick and to the underside of the swashplate assembly 90 degrees in advance of the point of desired pitch change. Movement of the control stick therefore causes a force to be applied to the swashplate, which precesses to cyclically vary the blade incidence. For example, in Figs. 1 and 2 (not shown), an upward force on the swashplate 35 applied by the rod 66 causes the swashplate to tilt to raise the link 32 and increase the pitch of the blade 12. The increased lift of the blade 12 then produces an upward movement of the plane of rotation of the rotor opposite to the blade 11. The effect of the lift on the masses 45, 46, 47 is to tilt the swashplate nose-up at increasing speed and hence to cause the helicopter to pitch nose-up. The blades are swept forwardly of the feather axis, so that if, for example, the blades are subjected to an upward disturbing force over the nose of the helicopter, a blade on the receding side is pitched up, producing an upward force near the rear of the swashplate and causing a blade on the advancing side to be pitched up, to balance the increased lift on the receding side. Similarly, if one blade develops greater lift than another, their incidence will be varied to compensate for it.

Patent GB-347182-A (GB)
Title: Process and apparatus for dehydrating chlorides
Filed: 1930-01-18
Abstract: Chlorides, for instance, of magnesium, cerium, and other metals of the cerium earths are partially dehydrated by sudden heating by contact with a surface, such as a metal plate, heated to 400-500 DEG C.  In the extraction from raw materials, the chlorides generally become contaminated with small amounts of calcium, and this is removed by adding to the solution of the chloride excess of the hydroxide of the metal in question.  After heating, impurities are removed, and the purified hydrated chloride is separated from the concentrated and cooled liquor.  From ,05-,5 per cent of calcium chloride is, however, retained in the chloride, in order that the final product, which has a porous structure and may contain 7-10 per cent water, is not too friable.  The product obtained is suitable for the production of the metal by electrolysis, either after complete dehydration by the process of Specification 344,601, or in the case, say, of cerium chloride, without this complete dehydration.  A suitable dehydrating table is described.  The Specification, as open to inspection under Sect. 91 (3) (a) comprises also preliminary fusion of the hydrated chloride prior to the sudden heating on a cast-steel table.  This subject-matter does not appear in the Specification as accepted.

Filed: 1938-01-20
Abstract: 498,427. Plug - boards. ROBINSON, W. A., CHAMBERS, W. A., and BRITISH ELECTRICON (LONDON), Ltd. Jan. 20; 1938, No. 1945. [Class 38 (i)] [Also in Groups XL and XX] A plug-board for use in a photographic printing apparatus comprises a number of sockets 31 in bus-bars connected to various points of a resistance 33, a number of sockets 32 in a neutral bus-bar, and a number of plugs 30 adapted to be selectively plugged into the sockets. Each plug 30 is connected by a cord 29 to a contact 22 of a selector switch rotated step by step by a coil 20. When the whole number of plugs 30 are not required in the sockets 31, the last unused plugs are plugged into sockets 32 of the neutral bus-bar. Thus pre-selected parts of the resistance 33 are successively inserted between the selector switch 21 and a printing lamp 6, the circuit of which also includes a line resistance 34 and a variable overall series resistance 35; and the printing light value is therefore varied in a predetermined desired manner at each step of the selector switch. Instead of controlling the current supplied to the lamp, a shutter or diaphragm grading the light may be automatically controlled. The selector switch is intended to be made as a complete rotary switch resuming the starting position after a complete revolution. For this purpose, the last contact 22 is connected to the coil 20 through a contact 20<1>, which is shunted by a resistance and is periodically opened and closed in a known manner ; and a terminal spot is marked on the master film to ensure that at the end of the printing operation the switch 21 shall be stepped on to a contact 22 connected to the neutral bus-bar. Then, the periodic closing of the switch 20<1> causes the coil 20 to operate the selector switch 21 step by step until it reaches again the first contact 22 past the last one connected to the neutral bus-bar and to the contact 20<1>.
