In a perforated-tape controlled page-printing typewriter, a carriage operates a switch A at or near the end of a line of print to initiate a carriage return and line feed operation. Closure of the switch A operates a relay RL which controls switches RL1, RL2, the latter switching on a motor M whereby a cam K closes contacts C to energize a carriage return solenoid CR while the former maintains the relay RL energized. When the carriage reaches the beginning- of-line position, a switch B is operated to energize a line feed solenoid PF and de-energize the relay RL. While the carriage is being returned, a tape reader solenoid TR is deenergized to stop operation of the tape reader. The switches A, B are operated by projections 20, 18 on the carriage, the switch B being designed for operation only when the carriage is travelling towards the beginning-of-line position by provision of a lever 12 pivoted to an arm 10 but prevented from pivoting away from the arm 10 by a stop (not shown). In a modification (Fig. 3, not shown) a switch MS5 delays carriage return until a space occurs between words. A further switch SWa, SWb permits the carriage to be returned in response to a signal from the tape reader and over-rides the automatic return.

Abstract: 1076158 Evaluating oxidation stability of oil ASSOCIATED ELECTRICAL INDUSTRIES Ltd 22 July 1964 [15 Aug 1963] 32317/63 Headings G4H H1D H3A H3B H3C H4A H5A H6B H6D H7A1 H7B H7G H7L H7P H8D H8E H12C H14B and H14D An electrolytic cell 1 supplies oxygen to a flask 2 as fast as a sample 18, of oil or petroleum, can absorb it, and the time taken to absorb a predetermined, maximum permissible, quantity is recorded, as a measure of the oxidation stability of the sample. The sample 18 may be heated and a catalyst employed. The anode 10 is enclosed in a tube 10' dipping below the NaOH in cell 1 and increased oxygen pressure in flash 2 and tube 3 depresses the liquid in tube 10' and stops the current through cell 1, so that oxygen is supplied only as fast as sample 18 absorbs it. The current supply to cell 1 powers coil 20, and a stabilised voltage supply powers coil 21, of a meter 4, causing a disc 19 to turn at a rate proportional to the cell current. Disc 19 drives a vaned wheel 27 between coils 25, 26, which produces alternate oscillation and non-oscillation conditions of the oscillator circuit shown. Hence pulses are delivered to an electro-mechanical counter 6 at a rate proportional to the cell current, and counter 6 is set to count down from a certain figure, representing a certain integral number of coulombs and hence grms. of oxygen produced by cell 1, and then to open switch 7, whereby clock 8 and digital timer 9, which started on closing switch 17 at the start of a test, stop. Fig. 2 (not shown) illustrates an alternative circuit in which disc 19 rotates a horse shoe magnet to operate a reed contact unit producing the pulses for counter 6. Fig. 1A (not shown) illustrates a flask-cell which automatically compensates for atmospheric pressure variations, which would otherwise effect the level in tube 10'.

Title: Magnetron
Inventor: DUNSMUIR ROBERT
IPC: H01J25/00
Filed: 1959-09-24
Abstract: 908,842. High-frequency tubes. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 21, 1960 [Sept. 24, 1959], No. 32552/59. Class 39 (1). In a magnetron oscillator an electron beam is injected from the cathode 8, Fig. 1, into an interaction space 15 to follow a helical path of decreasing radius around a central electrode 13 carrying a slow-wave structure which may be a hole and slot arrangement. The interaction space 15 is defined by the central electrode 13 and an outer electrode 14 and the cathode 8 is surrounded by an annular anode 10. The axial magnetic field has a value less than m#s/e, where m and e are respectively the electronic mass and charge and #s is the angular velocity of the wave on the circuit. The magnetic field is produced by magnetic polepieces 3, 4. Shunting polepieces 11, 12 establish a stronger magnetic field in region 6 of the magnetron than in region 7 in order to impart to the electrons in region 6 a circumferential component of velocity. In another embodiment for pulse operation, Fig. 2 (not shown), the circumferential velocity components are imparted by a circumferential electric field which is generated in region 6 by a surrounding magnetic coil, the coil being fed with current pulses synchronized with voltage pulses applied to the electrodes. An axially directed slit is provided in the cathode 8 and in the anode 10 to prevent them from acting as shorted turns. In another arrangement, Fig. 3 (not shown), a H.F. input signal is fed to a resonant structure comprising the anode 10 in order to produce a rotating electromagnetic field to accelerate the electrons circumferentially. The frequency of the input signal is less than that of the output signal derived from the slow-wave structure 13. The magnetron thus acts as a frequency multiplier. In Fig. 4, the cathode 66 is ring- shaped and provided with emitting surfaces 67 of part-helical shape. The annular anode 69 has co-operating part-helical surfaces 70. The static electric field between the cathode and anode surfaces gives the electrons circumferential and axial components of velocity. In Fig. 5, the electron beam is emitted from an annular cathode 87 and two electromagnets 89, 90 provide oppositely directed magnetic fields in regions 81, 85 so that the original direction of spiralling of the electrons is reversed in region 85. The magnetron output may be derived through a coaxial line 16, Fig. 1, or through a probe projecting into a waveguide.
