Title: Improvements in and relating to piston and cylinder engines
IPC: F02B75/22
Filed: 1950-08-24
Abstract: 695,470. Connecting rods; pistons. MOUCHLY, J. Aug. 24, 1951 [Aug. 24, 1950], No. 20962/50. Class 122(i) [Also in Group XXVII] In a power unit comprising a piston and a connecting rod, the latter is coupled to the former by a small end member of general spherical shape which fits within a spherical hole in the piston, the small-end and the mouth of the hole being so shaped that the piston and rod can be disconnected by rotating one relative to the other about their longitudinal axes through a fraction of a turn. An i.c. engine comprises a piston 10 operating in a cylinder 12 and a piston 11 secured to the piston 10 and operating in a cylinder 13. A connecting rod 24 is formed with an end 23 having spherical bearing surfaces and parallel flattened sides 23a. The end seats on members 25, 26 secured to. the piston; the member 26 has a rectangular hole through which the rod 24 passes and is so dimensioned that by turning the rod through a right angle the end 23 may be withdrawn from the piston. The rod 24 is connected to a crankpin 28 on self-aligning roller bearings 29 and is not otherwise secured. thereto. The crankpin projects from a flywheel 31 and the effective length of the connecting rod is at least 6.5 times the crank radius. The axis of oscillation of the end 23 is level with the skirt portion of the piston 11. The cylinders may be provided with labyrinth grooves in the walls, which grooves are inclined from the mouth in a direction opposite to the working stroke of the respective piston. Specifications 335,859, [Class 122(i)], and 373,251 are referred to.

Title: Improvements in or relating to apparatus for playing gramophone records
IPC: G11B3/085
Filed: 1942-11-25
Abstract: 561,891. Automatic gramophones. SHAW, M. N. H., and METCALFE, C. Nov. 25,1942, No. 20999/43. Divided out of 562,650. [Class 40 (ii)] In automatic gramophones, the stylus, after it has been deposited on the smooth peripheral margin of a disc record, is teased into the beginning of the record groove by means of the mechanism which lowers the pick-up. In the apparatus shown, the pick-up arm 1, Fig. 1, is pivoted on a horizontal pivot 2 on a bracket 3 at the top of a hollow vertical spindle 4 rotatable in a socket 5, and the pickup arm is lifted and lowered by a slidable stem 7 passing through the hollow spindle 4 and supporting the pick-up arm by a bracket 8 with an adjustable screw 9. The automatic horizontal movements of the pick-up arm are controlled by means as described in Specification 554,554, such means including a pair of levers 17, 18 co-operating with a stud 16 on an arm 14 attached to the hollow spindle 4, the lever 17 serving to swing the pick-up arm outwards, and the lever 18 serving subsequently to move the pick-up arm inwards to bring the stylus over the smooth edge of the record disc, this position being determined by adjustable abutments set according to the diameter of the record. The automatic lifting and lowering of the pick-up is performed by a lever 11 urged in one direction by a spring 30 and in the other direction by a link 13 operated by the automatic mechanism. According to the invention, the lever 11, after it has been turned by the spring 13 to deposit the stylus on the smooth edge of the record disc, is given a further movement in the same direction by the spring 30, whereby an arm 31 on the lever 11 bears on one end 32, Fig. 2, of a lever 33 pivoted 34, and deflects that lever causing the other end 36 of the lever 33 to bear on the stud 16 and thus push the pick-up arm slightly further inwards to tease the stylus into the beginning of the record groove. This movement is limited by the abutment of the end 36 against a stud 22 on the lever 18.

Title: Improvements in or relating to apparatus for use in scaring birds, animals, vermin, and for warning and like purposes
IPC: A01M29/06
Filed: 1925-08-22
Abstract: 261,832. Illingworth, C. H. Aug. 22, 1925. Producing intermittent audible signals; visible non-luminous signals.-The gravitational action of a number of successively falling bodies such as rollers or balls of steel, lead or other material is utilized to actuate devices to produce a noise, a light, or a movement to scare birds or vermin or to give warning, the interval between the successive falls being controlled by clock mechanism. In the form shown a casing, preferably of grotesque appearance, is fitted internally with a board 4 surrounded by a hollow coil 5 containing steel balls 6. A clock 9 is mounted on the board and its seconds arbor 10 carries a pin wheel controlling the escape of the balls from the lower end of the coil 5. As each ball escapes it drops on cupped portions of rocking arms 49, 53 and thence into a drawer 55 at the bottom of the casing. Electric circuits are completed through contacts on the arbor 10, so that in addition to the rocking of the arm 49, 53 produced by the balls, an electric bell is rung and electric lamps are lighted intermittently. The light may be directed on the rocking arms. The pin wheel may be replaced by a gate wheel or by a wheel having a number of curved depressions in its periphery to receive the balls. A number of such wheels may be arranged to operate in series. The balls may be arranged to run down a track and fall upon a trigger or like device that fires a detonator. In other modifications the balls strike bells or metal discs or actuate a bellows connected to a whistle, reed, or horn.

Title: Method for continuously adjusting the specifications of a product fraction stream withdrawn from an atmospheric distillation column especially the temperature of filtrability of a gas oil
IPC: B01D3/42
Filed: 1975-05-19
Abstract: 1495819 Automatic control of distillation SOC NATIONALE ELF AQUITAINE 19 May 1975 [30 May 1974] 21223/75 Heading G3R In a petroleum fractional distillation column, the filtrability temperature of a gas oil fraction withdrawn from the column is sampled and regulated in dependence upon measurements of various component flow-rates and the slope of the distillation curve of the petroleum in the gas oil zone:  As shown in Fig. 1, crude petroleum 2 is fed to a distillation column 1 where it is vapourized and expanded to allow separation into fractions including heavy gas oil 9, light gas oil 10 and  kerosene 11. Each fraction is passed through a steam stripping column 12, 13, 14 before removal on lines 23, 24, 25. The rate of flow in each of these lines is measured 67, 68, 69 and regulated 26, 27, 28. The light gas oil line 24 contains a sampling loop 32 connected by a pump 33 to an analyser 34 which produces and output signal related to the temperature of filtrability of the sampled fraction. The signal is stored in a memory 71 or fed directly to a control unit 35 for comparison with a desired value supplied on a line 42. The resulting error signal is normalized and processed in a PID controller, and may also be modified by actual and desired steam stripping flow signals, measured sidestream flow signals, and a signal related to the slope of the distillation curve. The modified error signal is then used, in a corrected form which allows for time lag between sample analysis and resultant action, to adjust the setting of the output flow regulator 30, thereby controlling the rate at which the light gas oil fraction is removed on line 10 and consequently influencing the product specifications exemplified by the temperature of filtrability.

Title: Spindle brake
IPC: D01H7/22
Filed: 1971-04-19
Abstract: 1281806 Directly-hand-actuated spindle brake ZINSER-TEXTILMASCHINEN GmbH 19 April 1971 [6 Feb 1970 7 Aug 1970] 21273/71 Heading F2E [Also in Division D1] Two brake components pivoted to a stationary part and pivotable by hand in unison between a braking position and a withdrawn position are secured together and to the stationary part by resilient means; means are also provided to hold the brake components in a stable configuration at least in the braking position. In one embodiment two brake components 15, 16, Fig. 1, each consist of an arm 21 or 22, Fig. 4 (underside view), and an extension 19 or 20. Each arm is pivoted at 23 to a fixed bearing sleeve 11 and is shaped to rest on an upper face of a collar 11<SP>1</SP> of the bearing sleeve in the disengaged position of the brake, Fig. 1. Each extension 19 or 20 has bonded thereto a brake lining 30 or 31, each lining having a radius of curvature equal to that of the spindle whorl 13 (one of several in a spinning machine) being braked, and subtending an angle of 90 degrees. The common axis 24, Fig. 4, of the pivots 23 lies on the side of the spindle whorl axis remote from the extensions 19, 20 in the disengaged position of the brake. The brake components are secured (removably) together and to the sleeve 11 by a U-shaped wire spring yoke whose in-turned ends are located in bores in arms 21, 22, and adjacent portions are located in grooves in the arms. The angle subtended by the yoke at the axis of the spindle whorl is seen to be greater than 180 degrees, and the ends of the yoke are on a line beyond the whorl axis, in the engaged position of the brake, Fig. 4. To apply the brake the operative lifts the extensions 19, 20, whose inner edges are initially in complete contact, causing the brake components 15, 16 to pivot about pivots 23. When the outer ends of linings 30, 31, make contact with the sleeve 11 at the ends of a diametral plane, the components are forced apart about meeting point 32 as fulcrum (see Fig. 4). Upon further pivoting, the outer ends of the lining occupy a position beyond the diametral plane and are slightly closer together again: this is an over-centre, "snapped-in" position where the braking position is automatically maintained. In Figs. 5, 6 and 9, two brake components 151, 16<SP>1</SP>, pivoted at 37, 38, respectively to a fixed collar 41 are urged towards one another by a resilient yoke 26<SP>1</SP> and are snapped into braking position, Fig. 6, by upward movement of yoke 26<SP>1</SP> and snapped out of braking position, Fig. 9, by downward movement of the yoke. The yoke may be removed for dismantling.

[Also in Division B6] In scouring or washing open width fabrics with minimum tension the fabric is caused to travel from a feeding station to a receiving station, whilst in association with a plurality of rotary members, first through a wetting-out tank, then through means for opening out the fabric widthwise and through the nip of a squeezing unit to a washing tank, next through means for opening out the fabric and through the nip of a squeezing unit to skeleton drums, some over and some in a rinsing tank, with means for rinsing the fabric, then to extractor means, then through a drier, and finally through a folder to the receiving station. In the arrangement shown fabric F travels from feed rollers 1 over a skeleton roller 2 to a lower roller 3 in a wetting-out tank 4. It then passes upwardly to a group of three rollers 5, 6, 7 the outer two of which are in the form of scrolls or oppositely screw threaded rollers to open out the fabric widthwise and uncurl the edges. From roller 7 the fabric passes between the nip of squeeze rollers 8, 9 and thence into washing tank or tanks 10 in which the liquid is agitated by shaker 13. Heaters 14 and 15 may be provided in tanks 4 and 10. From tank 10 the fabric passes over a pair of opening out rollers 17,19 and through the nip of a pair of squeeze rollers 20, 21 and thence around skelton drums 22, 23, 24, 24a and 25 the lower two 23, 24a of which are situated in compartments 26, 26a of rinsing tank 27. Associated with drums 22, 23, 24 there is a plurality of sprayers 28 directed against opposite faces of the fabric F. The sprayers 28 spray hot water whilst cold water is sprayed on the fabric from inside the drums. In addition fresh water is sprayed through pipes 28a on to the fabric as it leaves drum 24a. From drum 25 the fabric passes to a liquid extraction unit 32, then over opening-out rollers 29, 30, 31, through a drying chamber 33 and finally to an oscillating folder 36 by which it is layered in trolley 37. The rotary members are preferably driven in predetermined speed relationship, each with the other, to maintain the fabric of desired length and width.

Abstract: 1338309 Automatic phase control INTERNATIONAL BUSINESS MACHINES CORP 19 April 1971 [31 March 1970] 21762/71 Heading H3A In an arrangement for synchronizing a clock signal with received data, a gating signal is produced for each data pulse of a predetermined value and is applied to an error signal generator together with a signal from the clock oscillator to produce an error signal which applies control pulses to the oscillator directly and via an integrator. In one embodiment, Fig. 2, the clock oscillator signal on line 10 is fed to a pulse generator 20, which provides reset pulses for a bi-stable 22 and discharge signals for capacitor C1. The capacitor C1 then charges via positive source 26 until the arrival of a logical 1 on data line 5 sets bi-stable 22 to reverse the direction of charge, or in the event of a logical 0, until the arrival of the next capacitor discharge signal. The resulting sawtooth signal on line 6 is then applied to voltage/current converters (51, 54, Fig. 4, not shown) the outputs from which are sampled by a gating signal also derived from the controlled oscillator signal to produce a pulse signal having a magnitude dependent on the phase error. This signal is then fed to an integrator, Fig. 5 (not shown), to produce a control signal for the oscillator having a large short duration component and a small long duration component. In an alternative arrangement, Fig. 3 (not shown), the sawtooth signal on line 6 is derived directly from the clock oscillator, which is a sawtooth generator.
