Title: Improvements in or relating to thermionic valve cyclic control arrangements
Inventor: BRAENDLE ERNEST WILLIAM
IPC: H04K1/00
Filed: 1947-10-06
Abstract: 649,332. Thermionic distributers. STANDARD TELEPHONES & CABLES, Ltd. Oct. 6, 1947, No. 26807. [Class 40 (iii)] [Also in Group XL (c)] Apparatus for generating a series of cyclic control waves each having a maximum or minimum value at a different instant during the cycle comprises a master oscillator and means including frequency dividing stages for generating trains of waves in harmonic relationship, a suitable selection of the trains being combined to produce the control waves. The apparatus is similar to that disclosed in Specification 510,710 but avoids the use of a low master-oscillator frequency by employing frequency-dividiiig in place of multiplying stages. Fig. 1 shows an embodiment for generating eight waves which trigger in succession eight oscillators providing the carrier for a secret communication system (see Group XL (c)). A master pulse generator 1 produces a train of rectangular pulses at frequency 4F and applies them to a switching pulse generator 2 which in turn produces at terminals 3a and 3b two oppositely-phased trains at frequency 4F. Generator 1 is also applied through differentiating and limiting circuits 4, 5 to trigger a multivibrator 6 with two stable states. This multivibrator acts as a divider to produce an output train at frequency 2F and the output then actuates switching pulse generator 7 to produce at terminals 8a and 8b two oppositely-phased pulse trains of frequency 2F. The process of division is repeated by elements 9-13 and results in two trains of frequency F at terminals 13a and 13b. A typical wave arising out of the combination of the pulse trains obtained from terminals 3a, 8b and 13a is shown in Fig. 4 and is seen to exhibit a maximum value at instant 3. With the system shown, producing three pairs of trains at frequencies 4F, 2F and F respectively, eight waves exhibiting maximum values at different instants during a cycle are obtainable. The addition of a further stage of division will provide four pairs of trains from which sixteen control waves may be obtained, and in general N pairs of trains will provide 2N waves. One of the eight carrier oscillators 14 is shown connected to receive on its grid the wave illustrated in Fig. 4 and has a blocking bias so that only the maximum value of the wave will cause oscillation. The other oscillators are connected in the seven other possible ways to the pairs of terminals 3, 8 and 13. Isolating devices such as rectifiers 16, 17, 18 are included in the connections. A further embodiment Fig. 2 (not shown), employs both dividing and multiplying stages, the master pulse generator operating at an intermediate frequency. As an alternative to using the maximum value control may be effected by the minimum value of the control waves. Devices producing sine and half sine waves may be used in place of the rectangular pulse producing devices.

Title: A rotary piston and cooling means therefor
IPC: F02B55/04
Filed: 1965-06-24
Abstract: 1,116,652. Rotary-piston internal combustion engines. TOYO KOGYO KABUSHIKI KAISHA. June 24, 1965 [June 24, 1964; July 21, 1964 (3)], No. 26864/65. Heading F1F. A rotary-piston and cooling means therefor in a rotary-piston I. C. engine of the kind having an annular casing with a two-lobed epitrochoidal inner profile and a three-sided piston eccentrically mounted on a crank-shaft for planetary rotation within the casing, includes a hollow piston having a plurality of spaced partitions extending radially or substantially radially outwards from the piston boss to the peripheral wall of the piston and also between the piston side faces at an angle inclined with respect to the piston rotational axis to provide chambers through which cooling liquid circulates. In one embodiment, cooling liquid is delivered to a duct 17, Fig. 1, in the casing end wall 2 and passes through an aperture 15 in the piston side face through ports 13, one to each cooling chamber 12 on rotation of the piston. The liquid leaves the cooling chambers by way of ports 14, one to each chamber, aperture 16 and duct 18 in the casing end wall 2'. The ports 13, 14 are located at the radial innermost points in the chambers 12 and the partitions 9, Fig. 3, which extend radially outwards from the piston boss 7 to the peripheral wall 10 of the piston are inclined with the inlet ports 13 aft of the outlet ports 14 with respect to piston rotation so that when deceleration of the piston occurs during its rotation with consequential decreased centrifugal force the cooling liquid is forced out through the ports 14. The partitions 9 instead of being inclined at a constant angle, may have a variable inclination across the width of the piston to provide a curved partition at a somewhat steeper angle. Also, the partitions 9 instead of extending radially outwards from the boss 7 may be inclined rearwardly outwards with respect to piston rotation. In another embodiment, the cooling liquid is delivered through an axial duct in the crank-shaft 3 which is connected by radial bores in the crank-pin 5 which open through ports in the piston boss into the chambers 12 as the piston rotates. In this case, the cooling liquid enters the cooling chambers at the midtransverse plane of the piston and leaves the chambers by both the ports 13 and 14, the partitions 9 then being inclined forwardly from the mid piston plane on opposite sides thereof to provide chevron-shaped partitions. These chevronshaped partitions may also have a variable inclination from the apex to the outer ends to provide helical flow of the cooling liquid.

Title: Improvements in or relating to the control of coal-washing apparatus
Inventor: WALLACE WALTER MAY
IPC: B03B5/24
Filed: 1954-09-17
Abstract: 796,409. Washing coal. AUTOMATIC COAL CLEANING CO., Ltd. Dec. 28, 1955 [Sept. 17, 1954], No. 27014/54. Class 82(2) A system for controlling coal washboxes comprises a plurality of fluid-operated valves (3a &c.) for regulating the removal of discard from a coal washbox, a governor (4) responsive to the quantity of discard material in the washbox, and a pilot valve (2) for the automatic control of the fluid supply to the said 'regulating valves, the governor being operatively connected to the pilot valve so that the indications imparted by the governor to the pilot valve control the pressure of the fluid supply for operating the said regulating valves. In the Fig. shown, air under pressure is fed to pilot valve 2 from a supply 1; a governor 4 is connected, e.g. via a cam or diaphragm, to the valve 2 which may be of the kind described in Specification 722,993 [Group XXIX] and which controls the supply of air to the discard regulating valves 3a &c. situated in the discharge compartment and controlling the flow of air between such compartment and atmosphere. The wash-box itself may be operated via valve 7 by air from vent 1 or by a separate fluid supply, water being supplied at 8 and raw coal at 9. Pulsation of water in compartments 11 stratifies the coal &c., shale being discharged between gates 15, 16. Valves 3a &c. control the air outlet from discharge chamber 17 to atmosphere; closure of 3a &c. suppresses the pulsations of water between the said gates and stops shale discharge, whereas their opening permits both pulsation and discharge. Governor 4 responds to the thickness of shale layer 14, so actuating the pilot valve 2 and air supply to the valves 3a &c. as to open the latter and allow shale discharge when the layer 14 increases, and vice versa, so as to maintain a substantially constant shale layer. A recorder 6 of air supply pressure fluctuations may be calibrated in terms of tonnage of material extracted or any other faction of the degree of valve (3a &c.) opening.
