[Also in Division E2] In a washing and centrifugal machine or dishwasher having a door giving access to a rotatable part which is adapted to be driven at two different speeds, a locking mechanism for the door comprises an electro-magnet having a core 1, located between two permanent magnets 3, 4, and having a coil 2 which is connected to the terminals 5, 6 of an alternating voltage source through one of two diodes 7, 8 and a switch 9 which may be actuated by a programming device. When the machine performs the centrifugal operation, the polarization of the core 1 is such that it is attracted by magnet 3 and a member 13 engages a hook 14 to lock the door in the closed position. On reversal of the polarity of the core 1, it is attracted by the magnet 4 so that the door is unlocked. This may operate whilst the machine rotates at low speed during a washing cycle.

Abstract: 288,621. Schneider et Cie. April 14, 1927, [Convention date]. Ordnance, muzzle-loading; design; chambers; breech mechanism.-The base of a projectile and the breech-block or obturator of a muzzle-loading or other gun are made with interengaging male and female parts forming a chamber for the propellent cartridge. In the form shown in Fig. 1, the cartridge G is in a socket F in the base of the projectile C, which socket fits over a projection D on the breech base B of the gun A. The cartridge is fired by a primer H struck by a fixed or movable firing pin E. The gases are confined within the socket F until this leaves the projection D; the gases then expand into the barrel A and partly escape through a hole I. In modifications, a socket containing the cartridge at the base of the projectile fits into a recess in the breech base of the gun, or into a recess in an obturator carried by a. breech-block, or over a projection on the obturator. In another modification, Fig. 7, the cartridge G is in a recess in a projection D on an obturator K, which projection fits into a socket F at the base of the projectile.

Abstract: 175,964. Krupp Akt.-Ges., F. Feb. 19, 1921, [Convention date]. Electromagnetic switches. - Overload circuitbreakers in which the core B of the overload switch is wound with two independent coils a<4> and D in the same sense and in parallel with one another, have, in circuit with them, a further switch f<1> which, if depressed, puts the voltage of the supply A on to the coil D and opens the circuit-breaker although there is no overload. In the case of a normal overload the coil a<4> is energized to open the main circuit, although a weaker current flows through the coil D and resistance E to keep the core elevated against the action of the spring C. A lamp G lights up in either case. A modification is described in which two circuit-breakers are provided.

Title: Spoked wheel having a rim strip and a method and apparatus for applying the strip to the wheel rim
IPC: B60B21/12
Filed: 1975-01-17
Abstract: 1499413 Applying a protective strip around the rim of a spoked wheel SCHWINN BICYCLE CO 17 Jan 1975 [4 Feb 1974] 2165/75 Heading B7C A spoked wheel comprises a rim 11 provided with apertures 16 for spoke nipples 15 and with a tensioned loop 21 of nylon or a non-metallic material having similar properties to nylon. The loop has an aperture (not shown) coincident with the valve stem hole in the rim base. Apparatus for placing the loop on the rim and cutting the aperture comprises a platform 32 vertically movable by a pneumatic cylinder 29 and carrying a pin 34 engageable in the valve stem hole of the rim, a cylindrically cutter 42 vertically movable relative to the platform by means of a pneumatic cylinder 37, and means  for drawing a strip 21 of material from a roll 26,  wrapping the strip around the rim, joining the  end of the strip to a portion of the strip, e.g. by friction-fusion or adhesive to form a loop, and then severing the loop from the remainder of the strip. Alternatively the strip may be severed prior to its ends being joined to form a loop. In operation; a wheel is first loaded into the apparatus and switches 35 are manually operated to effect lowering of the platform and wheel. When the wheel actuates switch 36 movement  of the platform is terminated and the said means is actuated to form a loop. The cutter drive motor 41 is then automatically energized and the cutter is automatically lowered to cut the aperture in the loop. On completion of the cutting of the aperture (and in response to actuation of a pressure switch), the cutter is automatically raised, and finally the platform 32 is raised to the wheel loading (and unloading) position. In the illustrated apparatus frame 39 carrying cutter 42 is swingable about the axis of cylinder 37 by a further pneumatic cylinder (43) (Fig. 2, not shown). Thus after raising the cutter, the frame 37 is swung to move the cutter out of alignment with the pin 34, and the cutter is not moved into alignment until after the loop has been formed. In an alternative apparatus (Figs. 6-9, not shown) the cutter is in permanent alignment with the pin 34. If a number of wheels of the same size are to be mounted in the apparatus, the pneumatic cylinder 29 may be rendered inoperative when platform 32 is in its operative position (Fig. 3), and the wheels are successively placed on, and removed from, the platform 32 without the latter being moved from that position. Sensors 54 prevent operation of the apparatus if the wheel is not properly positioned on the pin 34.  Breeching of an infra-red safety curtain bonded by frame 27 will stop the apparatus.
