Title: Method of and apparatus for separating liquids of different specific gravity
IPC: B01D17/02
Filed: 1956-07-18
Abstract: 845,413. Gravity separation. DEUTSCHE WERFT A. G. July 18, 1956 [June 12, 1956], No. 22303/56. Class 46. In a method and apparatus for separating a mixture of two liquids of different specific gravity containing air, such as oil and water, the mixture passes first through a de-aerator and then a separator both of which are on the suction side of a pump, the de-aerator also has a connection to the pump for the separated air. The mixture enters the separator through an inlet 5 and meets a guide wall 32 having perforations 33 at the top. A primary separation takes place, some of the oil rising to the head 6a while the remaining liquid passes through the perforation 33 or over the top of the guide wall into a chamber 34 and hence to superimposed chambers, formed by partitions 36, where final separation takes place, the oil passing through pipes 40 to a chamber 48 from thence it rises through pipe 49 to the chamber 6a, and the water passing through gaps 42, between the side walls 41 of the chambers, to a collecting tank 46 which communicates with a discharge pipe 47 connected to the pump. The chambers may be provided with heating means 44. The chamber 6a has two vertically spaced electrodes connected to a relay such that when oil covers both the electrodes the relay operates and closes a valve in the line from the separator to the pump and opens a valve to admit water under pressure to the bottom of the separator to force the oil out of the chamber 6a. When water again covers both the electrodes the water pressure is cut off and the valve in the line from the separator to the pump is opened.

Title: Improvements in or relating to means for testing vehicle wheel brakes
IPC: G01L5/28
Filed: 1935-08-08
Abstract: 446,391. Testing vehicle brakes dynamometrically. SHORTLAND, R. A., 2, Burford Avenue, Whalley Range, Manchester. Aug. 8, 1935, No. 22364. [Class 106 (ii)] Comprises a construction of tool for turning the wheel against the influence of the brakes. A hand lever 9, a hook member 1 and a jaw 3 are pivotally connected by a bolt 4, the jaw 3 being provided with several holes for adjustment to tyres of different size. A cylinder 11 containing a spring 12 and pistons 13 has a pin 10 which is passed through a hole in the jaw 3, a pin 14 projecting from the piston through a slot 15 in the cylinder also passing through a hole in the lever 9. In use, the wheel being jacked up and the brake applied, the hook 1 is passed between the spokes to engage the inside of the rim and the enlargement 6 of the jaw 3 placed to engage the outside of the tyre. The lever 9 is now moved upwards and when sufficient force has been applied, the wheel is turned against the influence of the brake. During this movement, the spring 12 has been compressed an amount indicated by a friction washer 17 in the graduated rod 16 fixed to the piston 13 and passing through the end of the cylinder. This gives the measure of the force exerted. For use with disc wheels, the hook member passes right across the wheel and engages the outside of the tyre diametrically opposite to the part 6. When the device is employed always with wheels of the same size, the jaws may be relatively fixed.

Title: Improvements relating to printing machines
IPC: B41F13/14
Filed: 1923-09-12
Abstract: 222,652. Pickup, W. Sept. 12, 1923. Tripping and like arrangements. - Printing- machines of the kind in which a number of printing-rollers are driven at equal speed are constructed with means for setting the printing- rollers relatively to their driving-shafts while the machine is in motion. Each roller is separately adjustable by a knob or its equivalent provided on a rotating part to which it is connected by gearing, and the arrangement is such that an angular displacement of the knob on the rotating part causes an adjustment of the printing- roller in one direction. The rotating part is preferably a hand-wheel 10, adapted to adjust the printing-roller in the other direction in known manner when the wheel 10 is retarded. In the form shown, gear wheels 1 for rotating the mandrels 3 of printing-rollers are driven from a crown wheel, and each wheel 1 is freely mounted on a sleeve 2 fixed to the mandrel 3, and the parts 1, 3 rotate together owing to the engagement of a worm wheel 4 on sleeve 2 with a worm 6 mounted in brackets 7 fixed to wheel 1. To adjust the wheel 1 on its mandrel 3 when the machine is in motion, the hand-wheel 10 is formed with a worm 12 engaging a worm wheel 8 geared to the shaft of worm 6, so that, when the wheel 10 is retarded bv band, it causes the worm 12 to operate the worm 6 and so causes relative movement between the wheel 1 and mandrel 3 in a known manner. The wheel 10 is formed with internal teeth 13 geared by a pinion to a pinion 15 mounted in a plate 10<a> freely mounted on the mandrel 3 and held by an annular member 19 against axial movement. The shaft of pinion 15 is mounted in the plate 10<a> and terminates in a knob 17 which normally rotates with the wheel 10 without rotation about its own axis. If, however, the knob 17 is gripped by hand while the wheel 10 rotates, the knob 17 is caused to rotate, and the gear 15 operates the gear 13 and causes the wheel 10 to advance. and the worm gearing 12. 8. 6, 14 causes a displacement between the wheel 1 and mandrel 3. A guard prevents injury to the operator by the worm gearing.

Filed: 1964-06-02
Abstract: 1,010,129. Control of A.C. motors; switching control systems. GEORGE W. DAHL CO. Inc. June 2, 1964, No. 22864/64. Headings H2H and H2J. A split phase motor has reversing windings each connected in series with bridge rectifiers 17-20 or 30-33 which are respectively associated with silicon controlled rectifiers 25, 35. Terminal 46, together with terminals 48, 50 provide power for a pre-amplifiar circuit of the differential type, the input stage of the pre-amplifier comprising transistors 55, 56 whose bases are interconnected through a balancing potentiometer. A second stage of the pre-amplifier comprises transistors 60, 61 connected to the gates of the rectifiers 35, 25. Thermistors 70, 71 compensate for temperature changes of the silicon controlled rectifiers, whilst capacitors 72, 73 compensate for voltage transients. If the potential at input terminal 74 is negative, for example, transistors 55, 60 cause the rectifier 35 to be conductive, so placing a low impedance across the associated rectifier bridge. Voltage is applied to the preamplifier regardless of whether the motor is running or not, a Zener diode 54 being set to clip the voltage at a level sufficient to operate the pre-amplifier. The wiper arm of potentiometer 80 is mechanically coupled to the motor shaft, and connected to input terminal 75. In the null position, the voltage across terminals 74, 75 is zero, a current or voltage signal being applied to potentiometer 82. In another arrangement, the loads may be formed by relay windings or resistors instead of the motor windings. A capacitor may be provided for more sensitive operation of the relays.

Class 38 (4) In an engine-electric drive for a vehicle, wherein substantially constant engine speed is maintained up to maximum engine output and thereafter the generator excitation is reduced to prevent further loading of the engine, the generator G (which may be either the main generator for supplying the traction motors M, or an intermediate exciter for the main generator) has two differentially acting fields, one, n, of which is energized direct from the generator (either in series or shunt) and the other, m, is energized by an unsaturated engine-driven exciter E operating in conjunction with a constant voltage source B. The arrangement is such that when the voltage of the exciter falls below that of the source B the excitation of the generator is reduced, whilst when the exciter voltage rises above that of the source B a rectifier or polarized relay R allows current to flow from the exciter to the source B through a device H which operates to reduce the fuel supply to the engine. In a modified arrangement the field m is connected direct across the source B and a further field winding, acting in opposition thereto and in series with a rectifier, shunts the device H and rectifier R.

[Class 120 (ii).] In a machine for winding weft spools or cops having an axially movable winding spindle 11, shown in plan in Figs. 2 and 3, and an auxiliary thread-guide 23 reciprocated by the winding spindle against a spring 29 in order to form a bunch or reserve of thread at the commencement of winding, the guide 23, on completion of the bunch, being removed from the path of the spindle 11 by a ratchet device 37 and stopped, simultaneously releasing the thread, the auxiliary guide 23, 25 forms with a stationary guide member 22, 26 an angle which receives the thread 17 during winding of the reserve, the guide 23 being displaced on completion of the bunch by a lever 39 actuated by the ratchet 37 so that the thread slides off the free end of the stationary guide 22, 26 and is engaged by the principle guide 18. The lever 39 is pivoted at 40 to a disengaging lever 34, 35 held by a spring 38 against the hub 36 of the ratchet wheel 37, and carries a pawl 43 engaging the ratchet wheel 37. In reciprocating with the winding spindle 11 the auxiliary guide 23, through a pin 30, oscillates the lever 39 against the spring 44, the pawl 43 rotating the ratchet wheel 37 on each movement to the left, Fig. 2. When the hub 36 is turned so that the lever 35 engages the recess 56 the lever 34, 35 is rocked clockwise by the spring 38 and a pin 57 moves the lever 39 to the position shown in Fig. 3, the guide 23 being moved to the left and the thread slipping over the part 26 to the principal guide 18, the pin 30 being locked in the U-shaped part 41. The starting lever 32 is fixed to the spindle 33 carrying the lever 34, 35 and the ratchet wheel 37 mounted on a bush 45 serving as a bearing for a pin 46 carrying a disc 48 having a stop 47, Figs. 4 and 5, a spring 54 tending to rotate the ratchet wheel 37 so that a pin 55 fixed thereto abuts against the stop 47. In operation, the stop 47 is set for the desired reserve by turning the knob 49 and indicator arm 50. The lever 32 is then rotated anticlockwise, disengaging the lever 35 from the recess 56 so that the ratchet wheel 37 is turned by the spring 54 until the pin 55 engages the stop 47. The winding of the bunch then proceeds until stopped as set out above. In a modification, the stationary guide member is a straight rod 58, the auxiliary guide being formed as a bush 60 slidable thereon and having a cross-bar 63, Figs. 8 and 9.

Abstract: 590,193. Mining-machines. HAIR, C. E., HAIR, R. T., and BINKLEY MINING CO., [trading as HYDRABUSTER CO.]. Nov. 22, 1944, No. 23192. Convention date, April 13, 1944. [Class 68 (i)] A mining machine comprises a variable number of units such as end units D, E and multi-cylinder jack units C. At the outer end of each of the telescopic pistons 6 of a unit C is rigidly attached a pillow block 11, the arcuate surface of which engages loosely with a keyway in another pillow block 13 which fits loosely in a longitudinal recess 12 in the underface of a pressure pad b. During the breaking away of the rock, the piston is thus able to take up a position at an angle to the pad, which is arcuate in cross-section. Sliding of the pad longitudinally with respect to the cylinder block a is prevented by a lug and a screwed plug. Interfitting extensions 20 and 21 on adjacent pressure pads permit the formation of a continuous articulated pressure hood. The cylinder blocks are connected together by fluidtight pivotal joints formed by fitting a trunnion on one of the complementary lugs of adjacent blocks into a correspondingly shaped recess in the other, ball races 19 and grooves 16a for packing rings being formed at the same time. High-pressure fluid operates the machine and may be supplied to either side of each piston by means of passageways 28, 29, 30a, 31, 32a formed in the cylinder block and in the pivotal joint. At each pivotal joint complementary stops limit the arcuate movement of adjacent blocks. Specifications 575,038, 575,039 and 575,040 are referred to.
