Title: Mass spectrometer
IPC: H01J49/14
Filed: 1953-11-24
Abstract: 741,588. Heavy-ion-beam tubes. BENDIX AVIATION CORPORATION. Nov. 24, 1953 [Nov. 26, 1952], No. 32585/53. Class 39 (1). In a time-of-flight mass spectrometer the beam of ions is produced in bunches by forming an electron stream for short, relatively farapart intervals of time in the region where particles are introduced for ionization, a steady electric field being maintained for extracting the ions. A control electrode in front of the cathode is normally negatively biased, but is periodically raised to a positive potential by voltage pulses each, e.g. 0.01 microsecond long. The sweep of the cathode-ray in an oscilloscope connected to the ion collector is initiated a given time after the production of each pulse by the pulsing circuit. The presence or absence of ions of a given mass may then be determined. The spectrometer comprises cathode 10, control electrode 12, accelerator electrode 16 and electron collector 20, and ion extracting and accelerating electrodes 22, 24, 34 and ion collector 38. Electrode 34 imposes a high intensity ion accelerating field to compensate for random errors in position and motion of the ions under initial conditions as described in Specification 727,683. An electrode 36 in front of the ion collector 38 suppresses secondary emission. The ion collector may comprise an electron multiplier.

Title: Improvements in and relating to hydraulic servo-motors for actuating fluid pressure controlling valves
IPC: F15B13/12
Filed: 1934-11-13
Abstract: 447,198. Fluid-pressure servomotorcontrol systems. REINEKE-REGLER VERTRIEBS-GES., 26, Castroper Strasse, Bochum, Germany. Nov. 13, 1934, No. 32680. Convention date, Nov. 14, 1933. [Class 135] In a regulator, a servomotor is controlled by a pilot valve 4 elastically connected at 1, preferably through a leaf spring 3, with a diaphragm or other element displaceable or deformable with variations in the condition (e.g. pressure) to be controlled, the pilot valve being formed with pistons 7, 8 controlling ports 9, 10 leading to the servomotor, which pistons are bevelled and have a width less than the width of the ports. With the pressure medium, e.g. oil, flowing from the inlet 6 to the outlet ports 9, 10, a slight movement of the valve 4 upward or downward causes the valve to oscillate energetically, improving the control. To ensure maintenance of the vibration, particularly for end positions of the servomotor, an auxiliary valve 13 may be attached to the valve 4 by a spring 3<1>. Valve 13 is similar to valve 4 except that the outlet ports 9<1>, 10<1> discharge into the open.

Title: Improvements in the manufacture of cellulosic paper
IPC: D21H17/50
Filed: 1947-12-13
Abstract: Cellulosic paper is sized with a heat-hardened urea-formaldehyde condensate modified by reaction with a polyhydric phenol having at least 2 hydroxyl groups in meta position to each other, each of such meta hydroxyl groups having a hydrogen atom in ortho position thereto.  The condensate is applied, preferably in dilute alkaline solution, to the pulp in the presence of an acidic catalyst which precipitates the resin on the pulp.  The polyhydric phenol may be resorcinol, phloroglucinol, pyrogallol, 1.3-dihydroxynaphthalene; alkylated derivatives such as orcinol, cresorcinol, 2.6-dihydroxy toluene, 3.5-dihydroxy-o-xylene, beta-orcinol, n-propylresorcinol, monomethylphloroglucinol, 1-ethyl-3.4.5-pyrogallol, and they may be formed in situ by using halogenated derivatives such as tetrachlorresorcinol and trichloresorcinol and reacting under alkaline conditions.  The amount of polyhydric phenol to give an alkali-soluble product is between 2 and 20 per cent of the dry weight of the urea-formaldehyde condensate, which may itself be prepared from 1 mol. of urea and 1 to 4 mols. formaldehyde.  The modifying reaction may be under acid, neutral or basic conditions, the first giving better-coloured products, the preferred final pH being 5.5 to 6.5.  The alkali used to make the alkaline solution of the resin to be added to the paper pulp may be inorganic or organic, the latter being preferably a tertiary amine.  The acid catalyst may be an acid salt or an inorganic or organic acid.  The finished paper preferably contains at most 5 per cent by weight of resin with, if desired, other sizing materials such as starch, aluminium resinate, casein, glue or loading materials, China clay, calcium sulphate and other pigment matter, and may be used to make towelling or other specified paper products.  In examples: (1) an unmodified syrupy resin was made by reacting urea (1 mol.) formaldehyde (3 mols.) with hexamethylene tetramine as catalyst and used in aqueous solution to impregnate a Kraft fibre pulp, the pH being adjusted by aluminium sulphate, (2), (3), (4), the same resin was modified by resorcinol, pyrogallol and a mixture of triethanolamine and tetrachlororesorcinol, respectively, and used to impregnate a Kraft fibre pulp under acid conditions to give papers of improved strength.

Title: Improvements to telecommunication exchange line identification systems
IPC: H04M15/08
Filed: 1966-07-22
Abstract: 1,110,733. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORPORATION. 22 July, 1966 [23 July, 1965], No. 33048/66. Heading H4K. In a multi-exchange system, at least one of the exchanges is provided with facilities for obtaining the identity of any of the subscriber's lines connected to the system. The identity may be required in respect of a faulty connection or for billing purposes and the system may comprise a central office having a number of associated concentrators, all of the " Pentaconta " (Registered Trade Mark) type. Identifying local subscriber.-Central control OA applies an interrogating signal to the third wire of an established path JI1 whereby the signal passes backwardly over the switch train to the relevant subscriber's line circuit JA1 whereupon line identifier unit ID responds and sends the required identity to central control. Identifying concentrator subscriber.-As before, OA applies an interrogating signal to the third wire of the connection JI2 whereby the outgoing relay set JC used for this connection responds and passes the signal to a junction identifier unit PI. The latter causes the identity of the interexchange junction JD, connected to JC, to be transmitted over auxiliary junction VT to the concentrator whereat the latter's control circuit DC responds and applies a new interrogating signal to the incoming relay set JE attached to junction JC. As in the case of a central office local subscriber, DC thus obtains the identity of the concentrator local subscriber, e.g. AB2 and then reverts this identity back over the auxiliary junction to the central office. The identities are transmitted between exchanges in 2 out of 5 code by means of potentials on the 5 wire junction VT. The identifiers utilize diode networks and relay contact trees (Figs. 2 and 3, not shown).
