Title: Improvements in or relating to variable pitch propellers
IPC: B64C11/30
Filed: 1946-07-30
Abstract: 630,135. Variable pitch propellers. BREGUET, L. July 30, 1946, No. 22740. .Convention date, Aug. 11, 1944. [Class 114] In a propeller of the type in which the pitchvarying worms are actuated by a differential gear, the action of the differential is controlled by the shaft 6 through a gear-box from the engine-driven shaft 5. The speeds of the planet cages are controlled by two circulating pumps 50, 53 driven from these cages, throttling of the pump outputs causing movement of the cages and hence of the shaft 6. Rise in pressure in the pumps closes clutch 64 and so drives a pitch indicating and limit stop shaft 60. The device is controlled electrically by switches 98, 101, the former being operated to give hand control through the lever 76, which moves valve 75 to close the outlet of either pump 50 or 53 as desired. Switch 101 can be positioned as desired on contacts 102, 103 ... 107, and the necessary pump outlet closed until the pitch angle required is reached, when cams driven from the shaft 60 break the circuit of either solenoid 88, 109, releasing the valves 87, 89 to open the pump circuits.

Title: An electrical musical instrument
Inventor: HIYOSHI AKIO
IPC: G10H1/40
Filed: 1962-06-14
Abstract: 951,169. Electrophonic musical instruments. NIPPON GAKKI SEIZO KABUSHIKI KAISHA. June 14, 1962, No. 23001/62. Heading G5J. [Also in Division H3] An electrophonic musical instrument comprises circuits 1, 88, 89, 90 arranged to generate outputs simulating percussion. In a common output amplifier A85 feeding loud-speaker 86, these outputs are mixed with the outputs of the normal tone generators in box 94. Noise generator 1. A zener diode D4 generates random noise which is amplified by A3 and fed to circuits 88, 89. Tuned amplifier circuit, 88. When switch S17 is closed by key K18,the noise from circuit 1 is amplified by a transistor Q10 tuned by means of a resonant circuit L12, C11 in the collector circuit. The resistance and capacity in the circuit are chosen so that the conductivity of the transistor rises quickly and decays slowly, Fig. 2, to give a percussive effect at a pitch determined by the tuning. With no noise from circuit 1, operation of switch S17 is sufficient to generate a burst of oscillation shown in Fig. 3. A second circuit including transistor Q20, switch S27 and key K28 is tuned to a different frequency and may have different attack and decay characteristics. The collector circuit of a transistor may include a number of resonant circuits (Fig. 5 not shown). The random noise content of the output from circuit 88 is controlled by a potentiometer R6. Ringing circuit 89. Transistor Q30 has a highly selective feedback loop comprising a bridged-T network of resistors R44, R45, R40 and capacitor C41,C42,C43 and a coupling resistor R46. The feedback is insufficient to maintain self oscillation. On closure of switch S37 by key K38, an input signal stimulates oscillation at the characteristic frequency of the circuit. The decay time is controlled by a resistor R40. Musical triangle, circuit 90. Two multivibrators 91, 92 are tuned so that one generates a frequency nearly but not exactly twice the frequency of the other. The two frequencies are fed to a transistor Q70 controlled by switch S77 and key K78. The transistor circuit controls attack and decay as in circuit 88 but it is not selective. Simple percussion circuit, Fig. 6. To produce an oscillation like that shown in Fig. 3, it is sufficient to charge a capacitor C116 from a battery 126 and to discharge it through a resistor R118 under the control of a switch S124 and a key K125. A tuned circuit L123, C122 gives the output a characteristic pitch. Switch construction, Fig. 4c. The potentiometer switch 5 comprises a resistance film 107 and a sliding contact 108 carried by a lever 102 which has a number of preset positions fixed by a spring 104 and notches A,B,C in the casing. The lever carries a knob 5.
Patent GB-1305858-A (GB)
IPC: G05D1/02
Filed: 1971-04-19
Abstract: 1305858 Automatic steering control TOKYO KEIKI KK 19 April 1971 [10 March 1970] 23151/71 Heading G3R To avoid undue wear on steering gear and waste of propulsive power in too-frequent steering changes when an autopilot responds to yawing of a ship, the manually-set limiter of a conventional autopilot system is replaced by an automatic limit-level setting circuit which controls the limiter threshold in response to the external disturbances affecting the ship. As shown, the ships' heading # is compared with a set course # i  in an adder 1 and the difference is converted to an electric signal # which is fed to an operational circuit 3 giving an output # 1  proportional to the input # and to derivative thereof. The signal # 1  is fed via a limiter 4, controlled by automatic limit level setting circuitry 18, to an adder 5, which also receives a rudder feedback signal # 2 , and the resultant is fed via amplifier 6 to relay 7 for driving a motor, oil-pressure or like power unit 8. The mechanical position of unit 8 is indicated by an output signal #, representative of the rudder order angle of the automatic steering system, and this is converted to the electric feedback signal # 2  by converter 9 and feedback circuit 10. The automatic limitlever setter 18 comprises a drive circuit 12 whose output # determines whether limiter 4 is in a pass mode (providing steering alteration signals # o ) or in a limited mode (wherein no steering alterations take place), and an operational circuit 13 whose output # 1  is derived from the output # of circuit 12. Circuit 12 limits the circuit 4 whenever the signal # is smaller than the signal # 1  which therefore determines the set limit level. Each time circuit 12 changes limiter 4 to the limited mode, by means of signal #, the output # 1  is increased but circuit 13 is such that its output # 1  decreases with lapse of time. Thus frequent disturbances, causing frequent limiting, increase the limit level to arrive at an equilibrium frequency of steering alterations. When the weather has improved and yawing of the ship becomes smaller the frequency of limiting decreases, the signal # 1  decreases and thus the set limit level also decreases. Electronic details of the devices 3, 4, 12 and 13 are disclosed, Fig.3 (not shown). In a modification, Fig.4 (not shown) the circuit 12 is fed with the output # 1  from circuit 3 instead of the signal #, or the limiter 4 may act before derivation of signal # 1  in circuit 3, Fig.5 (not shown). In another modification, Fig.6 (not shown) an integrator (15) adds a signal (# 3 ) to adder 5 such that the feed to amplifier 6 is proportional, derivative and integral of the deviation signal #.

Title: Improvements in or relating to autographic registers
IPC: F02D9/00
Filed: 1931-08-17
Abstract: 372,196. Autographic recorders. JACKSON, P. A., 336, West 2nd Street, Dayton, Ohio, U.S.A. Aug. 17, 1931, No. 23168. Convention date, Aug. 23, 1930. [Class 106 (i).] The superposed webs are fed by the reciprocations of a carriage the top of which constitutes the writing-table. The folded webs 15 are contained in the carriage 14 provided with a handle 44 and mounted for longitudinal sliding movement within the casing At the front of the casing is an issuing slot 21 and bridging the gap between this and the tabletop 16 of the carriage is a stationary plate 39. The webs are furnished with aligning holes adapted to be engaged by holding pins 23, 25 carried by levers 26, 36 mounted on the casing and carriage respectively. The webs pass from the stack, around the rear edge of the table and over the plate 39 to the slot 21 where they are held temporarily by the pins 23. If now the carriage is drawn rearwardly the pins 35 trail along the undermost web until they reach the next holes and consequently rise. The shaft 37 thus rocks clockwise and allows a pawl 34 to fall into engagement with teeth 33 fast with a bar 27 mounted for slight horizontal and vertical movements and linked at 30 with the lever 26. Continued rearward motion of the carriage therefore produces similar movement of the bar so that the webs are freed by the pins 23, and further movement of the carriage is prevented. If the carriage is now moved forward it pushes the first set of forms out of the casing and when the succeeding set enters the slot a lug 32 on the carriage engaging a stop 31 again advances the bar 27 to lower the pins 23 into the holes containing the pins 35. The latter are therefore pushed down and may be withdrawn by the rearward travel of the carriage to engage the next set of holes. A pawl 42 loose on shaft 37 ensures a complete rearward stroke of the carriage. In a modification the teeth 33 and pawl 34 are replaced by a stop adjustable into one of several holes on the bar 27 to allow for forms of different lengths. The webs are held to the table-top by a spring clip instead of by the pins 35.

Abstract: 877,406. Mixing liquids in flow. SULZER FRERES S. A. July 4, 1960 [July 23, 1959], No. 23290/60. Class 86  In a method of supplying intermittently a small quantity of an additive to a flowing liquid which must not come into contact with air or gases, a small quantity of the main stream 1 is by-passed at 2 into a by-pass 15 where it is intermittently dosed at 5 by the dosing pump 8. The mixture is then homogenized in the completely filled vessel 6 before rejoining the main stream in which the concentration of the additive will be nearly constant. The ratio of the liquids is adjusted by the regularity valves 3, 4. In an alternative arrangement, Fig. 4, the dosing pump 8 is a diaphragm pump and the liquid in the by-pass flows in the opposite direction to the mainstream, across the delivery pump 10, only the bypass having a regulating valve 3. The method is primarily applicable to the addition of ammonia to boiler feed water.

Abstract: 517,707. Shoots and hoppers. SEALDSWEET SALES ASSOCIATION. Aug. 10, 1938, No. 23596. Convention date, Aug. 10, 1937. [Class 78 (i)] [Also in Groups XVIII, I and VI] In a machine which is described as coin-freed, fruits are taken, one by one, from bulk, halved and presented to de-juicing reamers. The fruit is contained in a hopper having an inclined bottom 272 hinged at 273 and resting, in its lowest position, on a stop 274. The fruit gravitate, one at a time, through an opening 277 in a square sectioned elevator passage 276 in which a plunger 278 is . slidable. The plunger 278 has a slot 274a which engages an extension 275 of the bottom 272 and is operated through linkage from a crank on a sprocket 279. The passage wall is slotted to permit the working of the link 281. The single fruit admitted to the top of the plunger is elevated thereby and the bottom 272 is raised and lowered to agitate the fruit in the hopper and assist gravitation. The top of the plunger 278 is inclined laterally so that the fruit will roll off the plunger into a downwardly directed part 290 of the passage. The fruit is arrested at the mouth of the part 290 by three wing plates pivoted adjacent to the rim of the mouth and having inclined slots therein which are engaged by pins on a rotatable ring concentric with the mouth. The ring is provided with a projecting 'lug secured to a cable 309 actuated by a rotary cam.. The ring is returned, to close the mouth, by a compression spring action upon the projecting lug. Should more than one fruit be in the part 290, the escape of more than one is prevented by a number of levers 312, one for each wing plate, which are pivoted at their lower ends on pins 313 and project through slots in the part 290. The levers are-normally pressed inwards by leaf springs 314 and are pulled out by engagement with lugs on the wing plates, the arrangement being such that, when the wing plates are in the release position, the levers are in the fruit retaining position and vice versa. The fruit is dropped from the part 290 into the reamering- means.

Abstract: 892,357. Storing fermentable liquids. PERNOD & RICARD. July 7, 1960 [July 7, 1959], No. 23768/60. Class 49. Apparatus for storing a fermentable liquid, such as a fruit juice, under sterile conditions, comprises a storage tank 1 connected to a holder 10 containing an inert gas such as nitrogen at substantially constant pressure, through a pipe 6, a three-way valve 7, a pipe 8 including a sterilizing filter 11, and threeway valves 12 and 13. The valve 7 is connected to the valve 12 by a pipe 9 including a bubble tube 15 and sterilizing filters 11a and 11b. A reservoir 17 containing sulphuric acid is connected to the middle of the bubble tube by a pipe 16, including a valve 18, and to the pipe 8 through a valve 19. Sterilizing steam, from a pipe 4, or a fermentable liquid from a pipe 5, can be fed into the tank through a three-way valve 3 and a pipe 2. The apparatus can be vented to atmosphere through a pipe 14 connected to the valve 13. The apparatus is sterilized by admitting steam through the valve 3 and allowing it to escape through the vent pipe 14 and is then filled with inert gas from the holder 10. The tank 1 is then filled with fermentable liquid and the bubble tube 15 is charged with sulphuric acid from the reservoir 17. Valves 7 and 12 are then operated to put the tank 1 in communication with the holder 10, through the pipe 9, and the bubble tube 15, instead of through the pipe 8. If fermentation of the liquid commences, the carbon dioxide generated causes an increase in the pressure of gas in the apparatus, which is indicated by a marked increase in the rate of flow of gas through the bubble tube, compared with that due to ordinary temperature variations. One or more of the three-way valves 3, 7, 12 and 13, particularly the valve 7, may be replaced by pairs of twoway valves, each of which is preferably enclosed by a jacket filled with an antiseptic liquid or vapour at a pressure of several atmospheres.
