Title: Apparatus for separating liquids of different gravities, and indicating means therefor
IPC: B01D17/02
Filed: 1923-05-23
Abstract: 220,713. Lenz, C. S., and Jupp, G. E. May 23, 1923. Indicating action of; regulating delivery by varying power of motor. -A pump, which discharges the heavier liquid from a vessel in which mixed liquids separate according to their gravity, is automatically stopped when the lighter liquid, which is of a different viscosity, enters the suction passages. The invention is especially applicable in connection with the separation of oil and water on board ship. Water is withdrawn from a series of separating vessels 11, Fig. 1, through pipes 14, manifold chamber 15, pipe 16, pump 17 and discharge pipe 28. An auxiliary pump 23 also withdraws water through pipes 25, manifold chamber 24, and pipe 23<a>. The inlet ends of the pipes 25 are at a slightly higher level than the ends of the pipes, 14. If, in emptying one of the chambers, 11, the level of the oil sinks so that the oil enters the pipe 25 the increased viscosity in the pipe 23<a> reduces the speed of the pump 23 and of its operating motor 22. This reduction is communicated to the balls of a centrifugal governor 20 connected to the spindle 29 of a valve 19 on a pipe 18 through which motive power is supplied to the pump 17. The valve 19 is closed and the pump stopped before any oil can be discharged through the pipe 28. A plate 30 on the spindle 29 engages with the ends of spring-controlled levers 31, 32, the lever 31 being geared to the pointer of an indicator 38 and the lever 32 forming a switch in an electric circuit provided with a lamp 41 and a bell 42. As shown in Fig. 3 water is withdrawn from the tank 50 by a pump 56 to a discharge pipe 57 through a pipe 51, chamber 60, pipe 61, manifold chamber 54, and pipe 55. The chamber 60 is provided with header plates connected by tubes of rather small diameter, so that there is considerable friction on account of the increased viscosity if oil is drawn up from the tank. The consequent increased suction in the pipe 55 draws down a spring-supported piston in a chamber 65 connected to the pipe and thereby closes a valve 69 controlling the supply of power fluid to the pump 56. A signal circuit may be provided comprising a lamp and bell, as described in connection with Fig. 1, controlled by a needle indicator forming part of a Bourdon gauge. Fig. 7 shows an arrangement in which a pump motor 22 is driven by a dynamo 103, the circuit comprising a lead 104, spring conductor 93, lever 90, leads 97, 102 and a lamp 101. On the discharge main 81, 80 is provided a Bourdon gauge with indicating pointer 76 and adjustable pointer 77. Contact of the pointer 76 with the pointer 77 closes the circuit of a solenoid 86, which raises a trip 87, and allows the lever 90 to fall under gravity. The motor circuit is thus closed and current passes from the dynamo through lead 104, spring 93, contact clip 95, lead 105, lamp 109, and bell 106.

Title: Improvements in or relating to variable speed gearing and like mechanism for the transmission of power
IPC: F16D67/00
Filed: 1931-11-30
Abstract: 393,296. Variable speed gearing. SWAN, J. G., 14, Old Square, Lincoln's Inn, London. Nov. 30, 1931, No. 13674/33. Divided on 393,294. [Class 80 (ii).] A coupling device or unit comprising a planetary gear train such as 151, 163, 162, Fig. 3, and an hydraulic coupling 155, 160 in a rotary casing 152 and in which an input gear 151 is always rotatable as one with an input shaft 150 and with said casing and another output gear, such a planet-carrier 164, is rotatable with an output shaft 161, and the hydraulic coupling serves to connect the input gear 151 with a third or loose gear annulus 162 wherein the connection between said input and loose gears 151, 162 includes, in addition to the hydraulic coupling 155,160, a friction clutch 154, 157, which enables said connection to. be interrupted at will. In the form shown in Fig. 3, the clutch 154, 157 connects the rotary driving casing 152 through a splined loose sleeve 156 to the primary hydraulic element 155. By a control lever 169, the clutch member 157 may be slid against a spring 158 to the right so as to interrupt the clutch connection and make frictional connection with a fixed brake cone 159. The element 155 is thus held and exerts a braking action on the element 160 which is rotated backwards by the reaction of the load shaft 161, so producing increased torque with full shock-absorbing capacity. A toothed starter ring is shown at 153 for use on motor-vehicles, and a free-wheel 165 enables the engine to be used as a brake. The annulus 162 is secured to the element 160 by through bolts 170 and the gearing turns in a casing between the back of the element 160 and a plate 173, which gear casing communicates with an inner toric space 171 by ducts 31, 32 allowing circulation of oil. The annulus 162 and element 160 may be connected by a further sleeve 167 to a brake drum 168, and the control 169 may be interconnected with means for arresting the drum 168 and with means for arresting a drum 166 on the output shaft 161. In a modified arrangement, described in the abridgment of Specification 393,294 with reference to Fig. 1 thereof, the friction clutch serves to connect the secondary hydraulic element with the loose gear of the planetary train. In an arrangement described with reference to Fig. 2, (not shown) the friction clutch connects corresponding parts where a gear train with stepped planet gears is employed. Specification 393,295 also is referred to.

Filed: 1962-04-10
Abstract: 999,065. Haymaking machines. C. VAN DER LELY N.V. April 10, 1962 [May 15, 1961], No. 13856/62. Heading A1F. A haymaking machine has rake wheels 95 power driven from the power-take-off of a tractor 108 through shafts 86 and 80 and through chain and sprocket transmissions to the outer rake wheels. Each rake wheel is readily detachable from its mounting plate 69 to which it is secured against rotation by three pins 102 and against axial movement by a pin 103 extending transversely through the central shaft 101. The plates 69 are secured by spokes 68 to sleeves 64 fixed to the power driven shaft 49. A conical guard 62 protects the rotating shaft and spokes. The implement is supported on ground wheels 20, 21 which are turnable about a vertical axis and are also movable vertically to raise the rake wheels off the ground for transport. The tow bar 106 is turnable about a vertical axis 105 and is held in the transport position shown in Figure 1 by a rod 137 engaging lugs 137A and 137C. For operation, the tow bar is turned to point in the direction D and automatically lowers the rake wheels into the working position by raising the ground wheels through a linkage 120, 118, 114 and rods 124 and 128. Fine adjustment of the rake wheel height is achieved through the same linkage by operation of a hand crank and screw 136, 132. In an embodiment two of the pins 102 which secure the rake wheel against rotation are replaced by two brackets which extend from the central plate of the wheel and engage in recesses in the supporting plate. Reference has been directed by the Comptroller to Specification 869,894.

Title: Improvements in or relating to railway signalling systems
IPC: B61L13/04
Filed: 1922-04-28
Abstract: 200,462. Automatic Telephone Manufacturing Co., Ltd., and Hudd, A. E. April 28, 1922. Addition to 163,418. Electrical systems, non-automatic. -In signalling systems of the type claimed' in the parent Specification the transient current over the track section is caused to pass automatically on the passage of a train. Track circuits are arranged so that a train on entering a section deenergizes a track relay and on leaving the section brings about its reenergization. A short insulated section in one rail 1, 2 is provided at each end of the section and these are so connected that a train may enter or leave the section at either end. The figure shows one line of double line track for traffic from right to left. The relays 16, 17 are normally energized by holding circuits which are mutually dependent upon the other relay. Armature 31 is raised and the circuit to the lock magnet 18 of the signal lever may be completed at the contact 19. A train on rail 2 shunts relay 17 and thus both relays 16, 17 are de-energized. A circuit is closed from battery 8 over rail 2, train wheels, continuous rail, battery 3, relay 10, rail 1 and wire 20 to energize relay 10 which completes the circuit to the magnet 11 of the vibrator generator, the armature of which operates a make-and-break contact 25, which keeps the armature vibrating, and contacts 23, 24, which put the reversed batteries 4, 5 alternately to the main section of the divided rail. The train, however, at this time shunts the relay 13 as it passes through tha section. On leaving the section, the relay 10 is again energized and the vibrator generator put in action and it continues to vibrate for a short time after the train has cleared the main section so that the relay 13 is energized for a brief interval and rocks its armature to alternately energize the slow-releasing magnets 14, 15, the armatures of which complete the setting circuits to the relays 16, 17 and restore the apparatus to normal. In order to provide for emergency resetting of these relays, a switch 26 is provided for manually closing the circuit to the relay 10.

Title: Carrier wave circuit protection
IPC: H03F1/54
Filed: 1943-08-27
Abstract: 567,352. Wireless transmitting systems. STANDARD TELEPHONES & CABLES, Ltd. Aug. 27, 1943, No. 13995. Convention date, June 23, 1942. [Class 40 (v)] [Also in Group XXXVII] In a radio transmitter, protection is afforded against lightning discharge or other abnormal condition by balancing rectified carrier output voltage against a voltage derived from the supply source of the transmitter, want of balance being utilized to interrupt the carrier excitation and to disconnect the source of modulating signal. The carrier generator 1 is connected through a control amplifier 2 and intermediate amplifier 3 to the Class C power amplifier and modulator stage 4, from the tuned anode circuit of which the modulated carrier passes by a transmission line 26 to the circuit of the aerial 6. The output carrier is also shunted through a blocking-condenser 27 and coil 28 to a rectifier 29 giving a direct current through a resistance 32, meter 40 and relay coil 41. The supply source 7 for the anode voltage of the power amplifier is connected thereto through a regulator 8 and rectifier 9, and is also connected through a transformer 34 and voltage divider 35 to a rectifier 36 which gives a direct current through resistance 33, meter 40, and relay 41. Normally, these two direct currents balance and the relay 41 is unenergized ; but if an arc or short circuit occurs between the aerial and earth, the relay 41 pulls up, energizes a slow-release relay 43 and shorts itself at the contact 50. Contact 46 opens and permits battery 48 to apply prohibitive bias to the amplifier 49 ; and contact 51 closes to short-circuit the modulating-source 12, this source being normally connected through amplifiers 13, 14 to a transformer 11 in the anode supply lead of the amplifier 4. The smoothing - condenser 37 eliminates pulsations at the supply frequency, and the condenser 30 eliminates pulsations at the carrier frequency and at the modulating frequency, so that the circuit balance is not affected by the modulation of the carrier. In a modification, Fig. 2 (not shown), the rectifier 36 and transformer 34 are omitted, the direct current through the resistance 33 being supplied through a high resistance and potential divider connected between the anode supply lead 10 and earth.

Exciting.-To maintain the torque of a synchronous motor and to prevent its falling out of step upon increase of load or decrease of line voltage, the motor field 12 is automatically strengthened by shorting a resistance 17 in response to reduction of voltage across a relay winding 23 connected between two phases of the supply lines 15. As a modification the same effect may be obtained by strengthening the field of the, generator exciting the motor field.
Patent GB-397621-A (GB)
Title: Improvements in pressure emulsifiers
IPC: B01F11/00
Filed: 1932-05-18
Abstract: In emulsifying-apparatus wherein materials in a bowl or container 4, Fig. 1, mounted on a cylinder 2 is drawn into the cylinder through a valve, such as a ball-valve 5, by a piston 1, <PICT:0397621/III/1> <PICT:0397621/III/2> emulsification is effected by passage of the materials through a leakage path 3, between the cylinder and piston and restricted to a small part of the circumferences thereof.  The leakage path may be formed by a flat on the piston or a groove in the cylinder and may be furnished with obstructions 3<1> comprising transverse or substantially transverse grooves and ridges.  As shown, the cylinder is pivoted at the end 2<1> and the emulsified materials pass out through a lateral passage 8.  In a modification the cylinder is pivoted in a vertical position to a base plate to which a hand-lever is also pivoted, the upper end projecting into the container from which materials are drawn through a cylinder port, uncovered by the piston and remote from the leakage path. The emulsified materials are delivered through a cylinder port connected to a delivery pipe.  In a further modification a receiving chamber for emulsified materials is mounted above a vertical stationary cylinder and the piston-rod passes through the chamber and a cover therefor and is reciprocated by a hand-lever pivoted to a link on the chamber.  The piston-rod may be rigid with the piston or may have a rounded end engaging a recess in the piston; in the latter case the piston is spring-returned and the piston-rod may be pivoted to or loosely engage a recess in, the hand-lever, which is directly pivoted to the chamber.  The container is mounted by the side of the cylinder and communicates with a piston-controlled inlet port therein by a lateral passage; a stirring plate is suspended in the container by a wire connected to the outer end of the hand-lever.  In a further modification a vertical pivoted cylinder has a preferably flexible suction tube employed to withdraw emulsifiable materials from any ordinary container; the tube may be connected to a cylinder port or to a valve-controlled inlet in the end of the cylinder.  As shown in Fig. 8, the cylinder 2 has a tubular extension 23 carrying an inlet valve 5 and a perforated disc-like foot 24.  The cylinder is mounted in any container 26 for emulsifiable materials which may be maintained in admixture by the action of the member 24 on vertical movement of the whole apparatus.  The hand-lever 11 is pivoted to the piston at 13 and to a link 15 on the cylinder. Emulsified materials are delivered through a pipe 8.  A bracket arm 25 secured to the cylinder extends beneath the lever 11 and prevents overturning of the apparatus.  In the two last-described constructions the restricted leakage path 3 may be replaced by an extended leakage path formed by making the piston a loose fit in the cylinder as described in Specification 285,159, [Class 81 (i), Disinfecting &c.].  In all modifications the pistons may be mechanically instead of hand-actuated.
