Patent GB-477497-A (GB)
Abstract: 477,497. Manual exchange systems. STANDARD TELEPHONES & CABLES, Ltd. Feb. 12, 1937. No. 4303. Convention date, Feb. 12, 1936. [Class 40 (iv)] [Also in Group XL] An office, e.g. of a telephone exchange, connected with other offices by means of a number of carrier channels using a common medium such as a coaxial cable has a number of outgoing circuits which are arranged to preselect an idle channel and a number of incoming circuits one of which is always searching for an incoming call. Fig. 1 shows an outgoing circuit comprising adjustable filters VF1, VF2, and oscillator OS1. Whenever the receiving filter VF2 of an idle circuit is tuned to a frequency that is present on the common medium, SR1 pulls up and causes the stepping magnet SW1 to adjust the filters until an idle channel is found. When an operator plugs into the circuit, PR pulls up, lights the busy lamps BL, connects the power supply to the oscillator and disconnects SR1 to prevent further adjustment of the filters &c. She then presses one of the keys CS which remains latched and modulates the outgoing carrier with a frequency characteristic of the wanted office. At each office one of the incoming circuits, Fig. 2, as determined by the condition of a chain starting circuit ST has its relay AR and clutch magnet MC energized and the tuning of the filters VF3, VF4 and oscillator OS2 is thus being constantly adjusted. Whenever a carrier is received, CR pulls up, but this is without effect unless the carrier is modulated with the tone frequency characteristic of the office concerned. In this case BR, DR are energized also, releasing the clutch magnet and causing AR to fall after a brief interval during which an impulse is sent to the relay AR of the next idle incoming circuit to start its hunt. A calling lamp CL glows at a position selected by call distributing equipment CD. The operator there operates the left-hand springs of key KY2 to connect her set to the talking circuit and energize ER. ER extends the start circuit, extinguishes the calling lamp and lights the supervisory lamp SL, connects up the power supply and causes the carrier to be modulated by an " order tone " generated at OT. At the originating office, RM releases the depressed key, causing the relapse of BR at the incoming end. In response to the order tone, the originating operator informs the incoming operator of the wanted number and the call is then completed. When the calling subscriber clears, the originating operator removes the plug PL1 and the consequent removal of the carrier releases CR, DR, in the incoming circuit and extinguishes the supervisory lamp SL. The removal of plug PL2 completes the release by releasing ER.

An electric switch 12 comprises a substrate 13 having first printed circuit type contacts thereon, an insulating film 15 overlying the substrate and having an aperture registered with each contact. A diaphragm 16 overlies the film and has thin flexible circuits printed thereon forming second contacts registered with each aperture and facing the first contacts. A cantilever spring 21 has a projection 22 of elastomeric material, in alignment with the aperture, a cantilever spring 24 being adapted to snap into contact with the first spring, to move the projection 22 and to bring the first and second contacts into engagement. Depression of a key of a terminal keyboard causes interposer 11 to release the finger 24 which engages ear 23 and moves the finger 21 downwardly until finger 24 impacts stop-bar 25. Button 22 is pressed against the film 16 to close its associated set of contacts, the button being deformed to spread the area of applied force whereby the film 16 is wedged into the hole of the sheet 15. Spring 21 tends to pivot about the button 22 and assumes a double curvature to compensate for any movement of ear 23 after the contacts have closed. The sharp impact afforded by the spring 24 is absorbed by the spring 21. The inclined faces of supporting bars 19, 20 causes the free end of the finger 24 to be inclined towards the finger 21.

Abstract: 1486023 Colour television tubes PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 18 Nov 1974 [21 Nov 1973] 49859/74 Heading H1D The near-rectangular shadow mask 10 of a multigun colour TV tube is held with its rim surrounding or surrounded by metal frame 4 attached to the tube wall. Under electron bombardment both mask and frame are heated uniformly but to different extents. To reduce the effect of expansion of the frame on the mask the retaining lugs 11, 12 welded to or cut from each rim are twisted to allow bending in the radial plane containing the tube axis. A1- ternatively at suitable points between corners and side-centres both mask and frame may have rims twisted to face radially (Fig. 7, not shown), the lugs then being tangential to the walls and not twisted. Thin cylindrical pins (Fig. 6, not shown) may replace the lugs since they allow deformation in an axial plane in addition to other directions. If the mask is made of low expansion alloy, e.g. 36 : 64 w/w Ni-Fe, residual bulging or stretching of the mask due to changes in the frame may be compensated by setting the axes of the lugs or pins not at right angles to the tube axis, causing forward or backward movement of the mask as the frame changes size (Figs. 8, 9, not shown). If the mask is not of low expansion alloy, further compensation by known bimetal means may be required to correct for radial displacement of the apertures.

Title: Angle measuring instruments

Abstract: 1,272,038. Measuring position. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 21 Oct., 1970 [24 Oct., 1969], No. 50021/70. Heading G4H. In an angle position encoder as described in U.S. Specification 3,278,928, four divided discs are provided in two pairs. One of the two pairs of discs has n divisions and the other n + 1 divisions. Two of the discs, one from each pair are mounted one on each side of a single plate which is driven by a motor. One of the remaining discs is stationary and the other rotates through the angle to be measured. The discs are linked either capacitatively or inductively so that each pair produces a pulse train of n or n+1 pulses per revolution, together with a reference mark at a particular position in the revolution. A course measurement is made by counting the pulses between the reference marks for the two pairs, and a fine measurement is produced by counting the pulses between a reference mark and coincidence of the two pulse trains, i.e. vernier principle. The present invention resides in interpolating between the fine measurements. The two pulse trains i 1 , i 2  are fed to a bi-stable 1 which enables gate 2 on receipt of a pulse on the i 1  line. This permits counter 3 to start counting pulses from an oscillator 4 synchronized with a motor driving the disc. The counter has a capacity corresponding to the number of pulses produced by oscillator 4 in the maximum time interval between pulses on leads i 1  and i 2  when pulses on these lines are judged coincident, i.e. the maximum capacity of counter 3 corresponds to a fine interval. If the pulse trains are not at the coincident position counter 3 overflows and no measurement is recorded. When the pulse trains are at the coincident position the time interval and hence the position between coincident pulses is measured by the counts of counter 3, which are then transferred to a store 7. AND gate 6 is then enabled to indicate the end of a measuring cycle.

The absorbent liquids include water, alkaline solutions and solutions containing amino-acid salts and substances such as ethanolamine. The regeneration may be effected' by subjecting the absorbent which has passed through the ejector and separated from impurities thus released to the pressure drop created by the ejector. The absorbent may be heated during this treatment and if desired boiled. In another embodiment the absorbent after leaving the ejector and separation of evolved impurities is heated in a column to its boiling temperature and the thus heated absorbent is subjected to the pressure drop caused by the ejector. Steam released by this treatment may be used to preheat the absorbent from the ejector. In a further embodiment the pressure drop created by the ejector is used to draw in air which is passed to a column wherein the absorbent is undergoing an oxidising regeneration.
