IPC: F01P7/06
Abstract: 1,054,782. Axial-flow fans; cooling cylinders. DOWTY HYDRAULIC UNITS Ltd. May 11, 1964 [May 16, 1963], No.19553/63. Headings F1B and F1C. In a fan driven by the engine of a vehicle and arranged in a duct 43 adjacent the engine radiator 44, the pitch of the blades 13 is automatically adjusted by thermo-responsive means to maintain the engine temperature within a predetermined range, and at low engine temperature the blades assume their fine pitch position wherein they substantially close the duct. The blades 13 are sector-shaped. Upon an increase in engine temperature two wax-filled thermostats 33, 34 attached to a ribbed heat sink 30 and each having a plunger (not shown) engaging a radial edge of a slot in a plate 37, cause the latter to rotate relative to the shaft 28. This adjusts the positions of rods 22 which are connected to the tubular blade roots 19, and thereby rotates the blades about tubular hub extensions 17 in a pitch coarsening direction. The rods 22 pass through slots 20, 21 in the tubular extensions 17 thereby limiting the range of pitch adjustment and preventing radial separation of the blades from the hub. Additionally, double-looped torsion springs 23 anchor the blades radially. The torsion springs 23 and the effects of centrifugal force bias the blades to their fine pitch position. The fan hub 12 is secured to a driving pulley (not shown) by bolts 32. The duct 43 and fan may be arranged upstream of the radiator 44 with the thermoresponsive means downstream of the radiator. The thermo-responsive means may be incorporated within the engine coolant pump.

Abstract: 1,230,318. Control of A.C. motors; control systems for electrical furnaces. T. KAWABE, and Y. KAWABE. 27 Nov., 1969, No. 57978/69. Headings H2H and H2J. A transformer arrangement for starting an electric motor comprises a laminated core A, B, C, D having a by-pass magnetic path C<SP>1</SP>, the three primary windings T1, T2, T3, being arranged in series, and the motor connected to the junction between the windings T2 and T3. Initially, power switch K and neutral point switch S are closed, whereby the motor is supplied with reduced voltage. When switch k1 is closed, secondary winding t1 becomes effective to generate a flux which opposes and neutralizes the flux generated by the winding T1. The voltage applied to the motor is thus increased. The switch S is then opened and the switch k2 is closed so that windings t2 and T2 are placed in opposition. The motor is thus supplied with the full source voltage. The switch S may be dispensed with, the windings T1, T2, being wound on the upper part of limb B while winding T3 is on the lower part. The motor is connected to the junction between windings T1 and T2, Fig. 6 (not shown). The windings T1, T2 may be tapped, Fig. 9 (not shown). In another arrangement, the transformer has a secondary winding which develops a voltage for operating the secondary switches, Fig. 10 (not shown). The by-pass magnetic path may have a secondary winding associated with a switch for preventing flux leakage through the path, Fig. 11 (not shown). The primary windings T1, T2, may be connectible in parallel with the secondary windings t1, t2, by closure of the switches k1, k2, Figs. 14, 15 (not shown). The windings t2 or t1 may be omitted. A reactor starter comprises a magnetic core of the form described with two series-connected main windings each associated with a neutralizing winding, the main windings being in circuit with the motor, Fig. 22 (not shown). The main and neutralizing windings may be connectible in parallel. The various switching operations may be performed by electromagnetic contactors under the control of timing relays. Indicating lights are used in connection with the stages of the starting sequence. Push-button control and short-circuit protection may be provided as well as thermal over-current protection. The apparatus may be used for controlling other loads, such as electric furnaces.

Abstract: 1,230,692. Train control and destination indicator. WESTINGHOUSE ELECTRIC CORP. 1 May, 1969 [20 May, 1968], No. 22232/69. Heading B7N. In a system for transmitting performance and destination signals to a train from, e.g. a central office and for transmitting destination and train length signals from the train to a wayside station in which each signal is in the form of a 6-bit binary word, each train or wayside station receiver with its associated signal storage means is provided with means responsive to the arrangement of the received signals in the store to prevent reception of further signals when a complete message (two words) has been received and stored in correct order. In the train apparatus shown the received performance and destination signals are applied to terminal 42 preceded by a start signal to terminal 14 and clock pulse signals at 18 c/s. and word pulse signals at 3 c/s. are applied to terminals 40 and 43 respectively. The start signal operates flip-flop 16 which supplies a signal to AND circuits 18 and 20 to allow the signals to be fed into registers 10 and 11 under the control of the clock pulses. The performance signal is arranged to be a 6-bit binary number in the range 50-59 and the destination a similar number in the range 0-49. If when a word interval signal is supplied from terminal 43 the AND gate 15 and OR gate 13 detect a number over 50 in the performance signal register the flip-flop 16 is triggered to prevent reception of further signals. The contents of the performance register are processed by a signal reading device and used to control train movement. The contents of the destination register and that of a fixed train length signal register are applied at two word intervals via AND gates 32 to a further register 24 from which they are serially fed, by clock pulses supplied to AND gate 22, to transmitter 33 for transmission to a wayside station.

Case-shift mechanism.-Instead of only moving the case-shift pulley 62, as in Specification 873,920, in the present Specification the typeselecting pulley 51 is simultaneously moved to counter partly the effect of the case-shift pulley 62. When pulley 62 has completed its movement, the type-selecting pulley 51 is returned to its original home position, so that the 180 degrees shift of the type head 55 is completed. Key lock and action of case-shift key.-Depression of shift key 111 moves a pivoted bellcrank 102 downwardly to flex a leaf spring latch 104. A horizontal arm 105 of bell-crank 102 drives a pawl 113 against upstanding arm 114 of interposer 110, to displace the interposer below a leaf spring latch 110a and trip cycle bail 34. The filter shaft 37 then drives interposer 110 to displace one bail 36 that is associated with a bail 46 of a selector mechanism 40. At the same time, interposer 110 pulls a control link 101 leftwards to set a shoulder 95 into alignment with an extension tab 65 of the caseshift pulley lever 61. Rotation of cam-shaft 43 now results in the movement of the case-shift pulley lever 61 via rod 93 and also the movement via bail 46 of the type selecting pulley lever 50. As filter shaft 37 completes its rotation, the interposer 110 displaces pawl 113 counterclockwise and shift key lever 112 remains depressed. The case-shift pulley lever 61 is retained in the shift position by latch 80 until such time as the operator releases key button 111. Key lever 112 then rises due to its bias spring 118, to lift pawl 113 to a position free of arm 114, whereby spring 117 pulls pawl 113 into operative alignment with the upper surface of arm 114. Continued upward movement of the shift key lever pulls the end 107 of bell-crank 102 clear of leaf spring latch 104 so that the bell-crank 102 drives interposer 110 downwards to initiate another cycle. As the cam-shaft 43 rotates causing lever 50 to move clockwise, rod 93 is moved leftwards toward the point where shoulder 95 will engage tab 65 so that the latch 80 is released. The return motion of rod 93 to the right is accompanied by simultaneous movement of the case-shift pulley lever 61 to its home position. Specifications 1,187,507, 983,549, 976,473, 873,920, 855,127, and 842,327 are referred to.

The rate of formation of bubbles is proportional to the pressure. As each bubble leaves tube 11 there is a pressure fluctuation which is sensed by turbulence amplifier 17. The output of the amplifier 17 is therefore a fluid pulse train of frequency equal to the bubble formation rate. The pulse train is amplified at 20 and operates a pneumatic counter 21. The counter may be reset periodically, the count just prior to resetting being proportional to the pressure. Instead of sensing pressure changes in tube 11, pressure changes occurring when each bubble reaches the surface of liquid 13 may be sensed if the container has a restricted outlet 15.

Abstract: 1295817 Lasers QUANDIA CORP 14 July 1971 [20 July 1970] 32941/71 Heading H1C A helium-neon laser has its 6328 A output stabilized by referring it to an absorption characteristic of iodine 129 vapour. The I 2 <SP>129</SP> vapour is contained in a cell within the laser resonator, and has a transition which absorbs some of the laser output. Such a transition can be saturated, giving rise to the inverted Lamb Dip effect shown in Fig. 1b, the result being a rise in the laser output intensity at the centre frequency of the iodine isotope absorption line. I 2 <SP>129</SP> has a large number hyperfine absorption peaks, Fig. 5a (not shown), and the laser output may be reproducibly set to any one of these by a dithered cavity. Fig. 4 shows the laser tube 108 and the I 2 <SP>129</SP> cell in a cavity formed of mirrors 107 and 102, the latter being mounted on a piezoelectric crystal 74. The crystal receives a steady bias voltage and also a 935 Hz dither signal; this latter causes a very slight modulation of resonant frequency of the cavity, which in turn modulates the laser output intensity unless the laser is operating at the exact centre of the inverted Lamb Dip where its intensity/ frequency characteristic is flat. The intensity modulation is sensed by detector 105 and this adjusts the bias supply until the exact centre of the Dip is found. Resonator construction.-The resonator mirrors are adjustably mounted at 66, 68, Fig. 2, on an "Invar" (Registered Trade Mark) housing 50. The laser tube 22 is of "Pyrex" (Registered Trade Mark), and has a gas reservoir 30 formed by concentric cylinders. An I 2 <SP>129</SP> cell 36 is attached to the cylinders, and contains a reserve of solid I 2 <SP>129</SP>. The assembly has a copper heat conducting jacket 44 connected to a heat sink 56 in an otherwise insulating base 58. A magnetic shield 42 screens the I 2 <SP>129</SP> cell from stray fields. The mirrors, which are multilayer dielectrics, are shown in Fig. 3. The mountings are two rotatable discs 76, 78, which are interlocked by rims 88 and 90 to permit relative rotation about inclined faces 82 and 83. To align the cavity, the disc 78 which carries the mirror 98 is rotated through up to 180 degrees; if this does not produce oscillation, disc 76 is moved through, say, 5 degrees, and disc 78 once again rotated. This is continued until alignment is achieved. Laser clock.-Two lasers, which may be He<SP>3</SP>-Ne<SP>22</SP> or He<SP>3</SP>-Ne<SP>20</SP>, preferably the latter, may be set to different Dips within the I 2 <SP>129</SP> hyperfine structure; the two outputs are of very precise but different frequencies, and may be combined to give an accurate beat signal which can be used as a time standard, Fig. 6 (not shown).
