Abstract: 374,625. Fountain-pen caps. WEINGART, R., 1875, 52nd Street, Brooklyn, New York, U.S.A. June 5, 1931, No. 16464. Convention date, June 5, 1930. [Class 146 (iii).] A fountain-pen cap is formed of two members 12, 13 adjustable relatively to one another and to the pen body 10 and provided with complementary end-pieces 21, 22 forming a closed end for the cap when disposed in one plane but capable of movement into separated planes to provide an opening through which the nib can be projected. The end-pieces are formed as segments and are prevented from engagement with one another when moved into open position to prevent the transference of any ink leaking from the pen to the outside of the members. The meeting edges of the segments 21, 22, Fig. 1, are bevelled so as to form a complete closure for the nib. The inner member 12 is provided with a pin 15 sliding in an open-ended slot 16 in the barrel to permit of removal. A spring 23 holds the end-pieces in engagement. The outer member 13 is formed with a circumferential slot 18 extending half way round its inner wall, and connected with a longitudinal slot 19, the slots being engaged by a pin 17 in the barrel. A part of the slot 18 is formed in a spring-pressed pivoted clip segment 26 in the outer member, so as to facilitate removal of the cap, a depression 29 being formed in the barrel to enable the clip to be raised by the finger-nail. To uncover the nib, the outer member is rotated to the extent permitted by the pin 17 and slot 18, the bevelled surfaces of the end-pieces 21, 22 causing retraction of the inner member, and a spacing- shoulder 25 on the outer member preventing the two end-pieces from contacting. The cap is then moved longitudinally on the barrel to the extent permitted by the slot 19. A protuberance 30 on the barrel is adapted to engage a depression 31 in the clip section 26 to retain the cap in retracted position. In a modification, a screw 39, Fig. 4, in the barrel engages a longitudinal slot 40 in the inner member, and a slot in the outer member formed with a short longitudinal portion 37, a circumferential portion 36, and a long longitudinal portion 38. To uncover the nib, the outer section must be moved forwardly against the action of a spring 32 the extent permitted by the slot 37 to move the segment ends out of the same plane, and then rotated. In a further modification, the end-piece of the inner member is provided with an edge of V-shape, into the angle of which projects a triangular projection on the end-piece of the outer member, the projection acting to space the end-pieces apart when in the open position.

Abstract: 777,005. Automatic voltage control systems. GENERAL ELECTRIC CO. June 8, 1955 [June 9, 1954], No. 16485/55. Class 38 (4). [Also in Group XL (a)] The amplitude of the R.F. voltage applied to a mass spectrometer in which resonant ions of different mass are measured as the frequency is varied (see Group XL (a)) is automatically adjusted to the correct value at each frequency for optimum resolving power and sensitivity. The applied R.F. voltage is rectified at 22 and compared in differential amplifier 21 with a reference voltage derived from potentiometer 16, and an error signal is fed to grid 122 of the cathode follower 23 between oscillator 11 and spectrometer 10. The tapping 16a of potentiometer 16 is varied simultaneously with the oscillator tuner 12. In another embodiment the frequency is adjusted successively to preselected values by inserting preset condensers simultaneously. The correct preset resistors are inserted for determining the magnitude of the input to the spectrometer. Preset resistors between an amplifier which follows the spectrometer and a recorder may also be inserted for optimum recording sensitivity. An additional variable condenser may be permanently inserted in the oscillator circuit and operated to sweep the oscillator in the neighbourhood of each selected frequency. An automatic amplitude control circuit may also be used in this embodiment. The oscillator may be tuned by inductances instead of condensers.

Filed: 1950-07-07
Abstract: 691,607. Liquid-disposing apparatus. COTTEE, E. N. July 7, 1950, No. 17041/50. Classes 106 (v) and 116 A liquid-dispensing apparatus comprises a container for fruit syrup, a rotatable measuring chamber, ports in the measuring chamber through which the fruit syrup from the container and water or other diluting medium passes into the chamber, a discharge port in the chamber, a valve in the water supply passage, an operating handle for rotating the measuring chamber, and a striker plate carried by the handle to operate the valve, and means to admit air to the measuring chamber after each charge of syrup has been delivered therefrom and to allow air to bubble up through the syrup in the container whereby the syrup is agitated. As shown, the liquid:dispersing apparatus comprises a rotatable tapered hollow plug valve 8 disposed below a syrup container 5, the container being connected to the interior 9 of the valve, which acts as a measuring chamber, via a tube 10. In the valve position shown in Fig. 3, syrup flows from the container through the inlet port 11, whilst in another position of the valve it flows from the measuring chamber 9 through an outlet port 12 to emerge from a delivery spout 13 and thence to a drinking vessel. As the syrup leaves the chamber 9, water enters via the port 21, a striker arm and plate 18, 19 integrally connected to the valve-operating handle 16 having actuated a plunger-type valve 23 fitted in the water inlet pipe 20. The water therefore enters the drinking vessel simultaneously with the syrup. At the same time air enters the measuring chamber via a hole 14 in the plug valve casing 6 and a port 15 in the plug itself. On completion of the dispensing operation, i.e. when the syrup is again allowed to flow into the chamber 9, the air is constrained to bubble up through the incoming syrup thereby agitating it.
