Title: Improvements in or relating to Ion Beam Intensity Measuring Apparatus and Methods
Inventor: DALY NORMAN RICHARD
IPC: H01J49/48
Filed: 1967-10-31
Abstract: 1,171,700. Mass spectrometers. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 21 Oct., 1968 [31 Oct., 1967; 25 Jan., 1968], Nos. 49529/67 and 4067/68. Heading H1D. An ion beam collector system for use in a mass spectrometer to detect ions below a certain energy, e.g. metastable fragment ions, or for detecting ions within a certain energy range comprises an apertured electrode 8, Fig. 2, and a retarding electrode 9 which repels ions back on to the electrode 8 to produce secondary electrons which are detected by a scintillator 10, e.g. an Eu-loaded CaF 2  crystal, occupying the centre of electrode 9. The scintillator 10 is backed by a window 11 and the photo-cathode 12 of a photo-multiplier tube. The electrode 9 is maintained at a potential which is variable between a potential V F  slightly positive to the accelerating potential V A  of the ion source 1 and a potential which is slightly negative. With V F  positive to V A  all ions in the beam are repelled and a measure is made of thetotal ions present. With V F  negative to V A  parent and fragment ions approach the scintillator but strike it with insufficient force to produce a signal in the photo-multiplier, while metastable fragment ions in the beam are repelled to the electrode 8 where they produce secondary electrons which are accelerated to the scintillator. The resulting current in the photomultiplier is then a measure of the metastable fragment ions only. To assist in discriminating between low-energy ions and secondary electrons the surface of the scintillator is coated with a thin layer of aluminium which is opaque to the ions but transparent to the secondary electrons. The collector system also includes a second retarding electrode 15 in the form of a grid, or a slit, which may be at such a potential V B  which is less than V F , that ions of a desired energy range may be detected. Electrode 15 precedes an earthed electrode 6 and is preceded by an earthed electrode 16 which forms the resolving slit of the spectrometer. An electrode 7 suppresses any secondary electrons produced at the electrode 6. In a practical construction, Fig. 3, plate 116 mounted on block 22 corresponds to electrode 16 of Fig. 2; plate 106 mounted on steel pillars 23 corresponds to electrode 6; plate 108 mounted on plate 106 corresponds to electrode 8; plate 107 mounted on plate 106 by insulating bushes corresponds to electrode 7; plate 109 carried by a pair of steel blocks 25 mounted on glass pillars 24 corresponds to electrode 9; and plate 115 carrying a pair of fine wire mesh grids (not shown) and supported from blocks 25 by glass pillars 26 corresponds to electrode 15. Suitable dimensions are given. An alternative resolving slit of adjustable width may be mounted ahead of plate 116. Reference is made to the possibility of omitting electrode 8 of Fig. 2 and using electrode 7 as the source of secondary electrons. The magnetic analyser shown may be preceded by an electrostatic stage.

Title: Improvements in or relating to railway axle counting apparatus
IPC: B61L1/16
Filed: 1931-02-17
Abstract: 373,649. Train axle counting apparatus. VEREINIGTE EISENBAHNSIGNALWERKE GES., Siemensstadt, Berlin. Feb. 17, 1931, No. 5064. Convention date, March 27, 1930. [Class 105.] An apparatus for counting axles in or out according to the direction of travel comprises relays 3, 4 which are energized over track contacts 5, 6 and serve to control relays 1, 2 by which a current pulse is given to the counting-in device E or counting-out device A depending on the direction of travel. An axle moving in the direction of the arrow first energizes the relay 3 only, then the relays 3, 4, and finally the relay 4 only. In the first interval, relav 3 closes contact 30 so that relay 1 is energized over back contact 42 of relay 4 ; in the second interval wherein relays 3, 4 are both energized this circuit is opened at contact 42 of relay 4 but relay 1 continues energized over front contact 41 of relay 4, its own front contact 12, and back contact 21 of relay 2 ; in the third interval front contact 40 of relay 4 and back contact 32 of relay 3 are closed and energize relay 2 so that the counting-in device E receives a pulse since the contact 10 of relay 1 opens when this latter relay 1 is de-energized by the opening of contact 21 when relay 2 is energized. Passage of an axle in the reverse direction operates the counting-out device A in a similar manner. Condensers are inserted across the relays and counting devices to prolong the impulses. The relays 3, 4 may be energized by the inductive impulses arising from the passage of the train.

IPC: E05F3/16
Filed: 1926-02-25
Abstract: 248,382. Page, F. H. Feb. 25, 1925, [Convention date]. Operating and controlling doors by springs.- A coiled spring F in a barrel A attached to the frame has an arm B secured to its spindle E and the arm co-operates with a cam D on the hinged door, the arrangement being such that by the action of the cam the closing force is increased just prior to the movement of the door to the completely closed position. At the opening movement of the door, the roller C on the arm moves to the bottom of the cam, and the spring thereafter regains its initial tension. A further opening movement of the door causes the cam to engage the bottom of the fork in the arm B, which then acts as a stop. On the door closing, the peak of the cam engages the roller to increase the closing force applied to the door. The spring is attached to its box at J and a screw G prevents axial movement of the spindle E.

Title: Improvements in road contact devices for road traffic signalling apparatus
IPC: G08G1/02
Filed: 1936-02-24
Abstract: 467,354. Road signals for controlling traffic. SCOTT, W. H. Feb. 24, 1936, No. 5478. Addition to 419,533. [Class 118 (ii)] The road contact device described in the parent Specification is modified by forming the resilient bed, which supports the contact assembly, of strips of springy metal and resilient material such as rubber. The metal strip or strips serve to distribute the pressure of heavy loads on the bed to avoid local distortion. The form of the outer cover is also modified. As shown, the contact strips 1, 1<1> separated by a resilient insulating strip 2 are supported on one or more relatively thin strips 8 of rubber resting on a plain strip of springy metal 6 further supported on a relatively thick strip 5 of resilient material. This is carried by a further metal strip 7 which may also be springy and supported on another resilient strip 7<1>. The width of the strips comprising the contact assembly and its bed are such that the whole assembly inserted in a rubber tube 10 has substantially flat sides and bottom and a curved top. The body 13 of the outer cover is flat at the top and inclined at the sides, the top having a curved tread 18 projecting above the framework which is constructed substantially as described in the parent Specification. In order that light loads may affect mainly the contact spring assembly, the bed being compressed on heavy loads only, the strips of resilient material in the assembly and the bed may have holes of graded size and spacing, and the contact and other metal strips may be graded as to thickness and temper.
