IPC: H01H23/20
Filed: 1920-10-07
Abstract: 171,581. Fainter, F., and Ide, G. H. Oct. 7, 1920. Switches, quick-action, of the kind in which the contact-member is operated rapidly by a spring-controlled toggle linkage, have one of the links of the toggle provided with an additional articulation. In the tumbler switch shown in Fig. 1, the toggle consists of the link c and the compression link d pivoted together at k, the free end of the compression link passing through a roller e having a fixed axis in an extension f of the bridge. The link c is jointed to the operating tumbler-lever a by means of the pivot pin l; inclined faces m, n on the link co-operate with a face o of the tumbler lever to permit some lostmotion. In action, the toggle is moved over the dead-centre and the pivot pin k engages one side or the other of a slot in the contact-member to drive it rapidly. If the spring on the compression link fails, the mechanism is driven positively.

Title: Improvements in and relating to coin freed machines for the supply of table tennis balls and other articles suitable for coin freed delivery, by the insertion of one or more coins
IPC: G07F5/02
Filed: 1938-09-30
Abstract: 519,707. Coin - freed machines. ROSSITER, F. E. Sept. 30, 1938, No. 28402. [Class 27] In coin-freed machines the coins fall down a shoot 5 and pass partly through a slot in a sliding member 2, coming to rest on the inclined surface 6. The stop 7 is moved axially on the threaded bar 8 until the correct combination of coins 24 forms a rigid bar between the stop 7 and the pawl 10 either directly or through the intermediary of a pivoted stop 9. Thus when the drawer or sliding member is moved in Fig. 1 at right angles to the plane of the paper the coins release the pawl and allow the movement to proceed. During the movement the pivoted stop 9 is engaged by the fixed ramp 21 to release the coins and the latter drop into a coin receptacle as soon as they move laterally off the shelf 6. On the return movement of the drawer a spring 17 re-engages the pawl 10. Meanwhile the movement of the drawer is used to deliver articles on the intermittently - operated - gate - and - gravity - escape - principal. The forward movement of the drawer removes the lowest article 13 from the pile and drops it through an opening 15 for delivery; a second member 16 meanwhile moving forward to support the rest of the pile. On the return movement' another article is lowered into the slide for delivery next time.

Title: Method for determining the degree of wear of an element with known magnetic properties
IPC: G01M13/00
Filed: 1976-07-14
Abstract: 1537552 Detecting wear electrically SOC D'ETUDES DE MACHINES THERMIQUES 14 July 1976 [1 Oct 1975] 29195/76 Heading G1N The degree of wear of a first element in sliding contact with a second element is determined by measuring the variation in the reluctance of the first element as it slides past the second element. An inductive sensor 10 is positioned in bores 8, 9 of cylinder block 7 and liner 6 of an internal combustion engine 1 so as to have its end flush with the liner 6 so that during the reciprocating motion of the piston 2 all the piston rings 5a-e successively pass the sensor. The sensor output is connected via amplifying and filter stage 11 to CRT 12. With the piston 2 in its upper position sensor 10 supplies a constant level signal S1, then as the ring 5a passes in front of the sensor 10 a pulse I, is produced and similarly pulses I 2 , I 3 , I 4 , I 5  are generated as the remaining rings pass the sensor 10. Due to rings 5a, b, c being located in the steel head 3 of the piston whereas rings 5d, e are in the aluminium skirt 4 the level between the rings changes from S 1  to S 2 . The upper ring 5e is chromium plated on its outer surface in contact with liner 6 so that its permeability is lower than that of the other rings. Thus as the chromium of ring 5a wears away the reluctance of this ring increases in a greater proportion to that of the other rings and the output signal increases from I 5  to I' 5  to I" 5  as the wear increases. The sensors may be mounted in the cylinder on to the same level and in diametrically opposite relationship so that a deformation of the piston ring can be detected when there is no coincidence between the two pulses produced.
