Title: Radical anions for electron transfer dissociation
Inventor: HARTMER RALF
IPC: H01J49/00
Filed: 2009-12-04
Abstract: The invention relates to the fragmentation of biopolymer ions with multiple positive charges by means of electron transfer (ETD = electron transfer dissociation) in reactions with radical anions. The invention discloses using radical anions generated from an aliphatic (i.e. non-aromatic) compound with an electron affinity of between 0.3 and 0.8 electronvolts, e.g. 1-3-5-7-cyclooctatetraene (see Figure 1). The radical anions of these substances lead to dissociations by electron transfer with a high yield of fragment ions, and which have favourable properties for their handling and for the associated analytical methods. For example, the high volatility of the substances allows them to be fed to an electron attachment ionization source 8 from an unheated container 19 located outside the vacuum system of the mass spectrometer, making it easier to replace empty substance containers. The low molecular weight allows the measurement of even very light fragment ions, down to individual terminal amino acids.

Filed: 1957-04-01
Abstract: 882,926. Disc brakes. DUNLOP RUBBER CO. Ltd. March 27, 1958 [April 1, 1957], No. 10509/57. Class 103 (1). An automatic adjusting device for a disc brake comprises a pin 50 carrying a close-coiled spring helix 58 between a step 59 and ring 60 in a bore in a piston 26, the head 52 of the pin 50 being located in a recess 48 in the end wall 47 of cylinder 32 and abutting a bush 53 held against cylinder wall 47 by an annular concave star spring 54 whose outer arms 56 engage a closure cap 57 located in a recess 49 in the wall 47 by peening. On brake application, fluid pressure from a master cylinder, Fig. 1 (not shown), moves piston 26 to force a friction pad 22 against a disc 1, the pin 50 moving with the piston until a gap between bush 53 and cap 57, the normal brake clearance, has been taken up, further movement of the piston, due to wear, forces the piston and spring 58 to move relative to pin 50; on brake release the spring 54 returns the piston and pin until bushing 53 abuts the end wall 47 so establishing brake clearance. With the brake released, should the disc oscillate or vibrate and strike the pads 22, the pads, piston and pin 50 will move back against fluid pressure in the space 41 which is the normal static head of pressure of the braking system, the pin head 52 moving from the bush 53 into recess 48 without interfering with the frictional arrangement between the pin 50 and piston 26, the static head of pressure returning the piston to its normal position in which head 52 abuts bush 53 when the condition of the disc rotation allows. A ring 34 on the piston holding the sealing ring 33 in position is extended in an embodiment in Fig. 4 (not shown), to about the coiled spring 58, so replacing ring 60, whilst in Fig. 5 (not shown) the space to accommodate movement of the piston due to disc oscillation is situated between the coil spring 58 and the step 59 in the bore in the piston and in Fig. 7 (not shown) the pin head 52 extends into a bush which is peened into the end wall of the cylinder.

Abstract: 108,479. Olsen, F. J. July 31, 1916, [Convention date]. Variable - speed gearing; back-pedalling brake and freewheel arrangements. - In a two-speed hub for bicycles in which speed changes are effected and a brake is operated by back-pedalling, a clutch-sleeve z screwing on an extension of a sun-wheel x couples the sun-wheel either to the fixed axle r or to the planet carrier g, but is out of action when the gearing drives solid at the high speed. The gearing comprises also the following parts; a chain-wheel e on a toothed annulus d engaging planet-pinions f on a carrier g, which has a threaded engagement u, v with a clutch ring t, lost motion amounting to about a quarter of a revolution being allowed between the threads u, v; an axially movable member rotating with the carrier and formed at one end with teeth 14 to engage teeth 11 on the sun-wheel x, and at the other end with alternate deep and shallow notches 3, 4; a ring 6 with ratchet teeth 5 on both sides to engage the notches 3, 4 and other teeth on the clutch ring t; and a clutch sleeve p which, when moved to the left and rotated, operates a lever n, applying a brake l to the inner surface of the hub i. In the position shown, the sun-wheel is held against rotation by the clutch z, and the planet carrier g, drawing the sleeve t into engagement with the hub i, drives the wheel at reduced speed, To change the speed, the chain-wheel c is turned backwards; this rotates the sun-wheel x and moves the clutch z to the right to engage a surface 12 on the carrier g, and at the same time the teeth 5 move the sleeve l to the right and slip into the shallow notches 4, so that the sleeve is locked to the teeth 11 on the sun-wheel, and the teeth on the left side of the ring 6 first move the sleeve t to the left and then slip into the next spaces. The gearing then drives at the higher speed. to change back to the lower speed, the same operations are performed, the teeth 5 slipping into the deeper notches 3 so that the sleeve 1 is moved to the left by a spring 9 to prevent engagement of the teeth 14, 11. On back-pedalling farther than is allowed by the lost motion between the threads u, v, the sleeves t, p move to the left and operate the brake. Light springs 15, 8 prevent undesired movements of the sleeves t. z.
