Inventor: YANTES WILLIAM HENRY
IPC: B28C5/42
Filed: 1951-07-04
Abstract: 690,361. Mixing appliances. JAEGER MACHINE CO. July 4, 1951, No. 15858/51. Class 86 In a charging and discharging device for an end loading rotatable drum mixer, which comprises a hopper carrying a rotatable annular door for the drum opening, the means for mounting the annular door on the hopper comprises thrust ring members carried by the hopper and the door in face to face contact and a flexible sealing ring having its outer portion carried by the door remote from the contacting surfaces of the thrust members, and having its inner portion free and turned inwardly toward the drum opening in overlapping engagement with a sealing surface carried by the hopper. The forward or lower edge of the hopper 17, Fig. 2, carries a rotatable annular door 26 disposed between the hopper 17 and the rotatable mixing drum 10. The hopper 17 is pivotally mounted at 22 and by means of an actuating unit 45 can be swung about the pivot 22 towards or away from the drum opening for charge or discharge of the drum. In the charging position, Fig. 8, the annular door 26 engages peripherally in sealing relationship with an annular seat 16 carried by a flange 15a surrounding the drum opening 14 and rotates with the drum. An annular flange 38 carried by the door rotates in the space between annular flanges 29, 33 carried by the hopper and bears against a thrust ring 30 carried by the flange 29. A flexible sealing ring 40 is secured to the flange 38 so that its inner edge portion 43 can turn inwardly and engage in sealing relationship with a bevelled surface 34 on the flange 33. Lubricant fed from pressure fittings 36 passes along spaces between the flange 29 and the thrust ring 30 and into the space between the flanges 33 and 38 in which it builds up a pressure tending to prevent fines from entering between the flexible edge 43 and the surface 34 and from reaching the bearing surfaces on the members 30, 38. The actuating unit 45 comprises a fluid operated cylinder and piston unit 55, the cylinder. 56 being mounted for axial movement in a sleeve- 50 pivoted to a fixed support 46 and containing a spring 67 which urges the cylin-' der towards the hopper. A piston rod 59 carrying a piston 58 is in connection with the hopper 17. Pressure fluid under control of a manually operated change-over valve may be admitted to either side of the piston 58. When the fluid pressure is admitted to the upper end of the cylinder the piston moves forwardly and downwardly. Fig. 6. and the annulus 26 engages the seat 16 with resilient pressure derived from the spring 67. An alternative form of actuating unit, Figs. 11-15 (not shown), consists of a toggle-lever mechanism which may be set by hand-operated means to press against the hopper through an intermediate spring for resiliently engaging the annulus 26 against the seat 16. Specification 690,370 is referred to.

Title: Improvements in or relating to a draw bench having two feed units mounted in tandem
IPC: B21C1/30
Filed: 1964-04-16
Abstract: 1,045,537. Draw benches. M. VON BUSHE, and T. ALTENBRACHT, [trading as TH. KIESERLING & ALBRECHT]. April 16. 1964 [July 13, 1963], No. 15892/64. Heading B3P. A draw bench has two feed units, arranged in tandem, which feed the workpiece alternately, each feed unit comprising a piston and cylinder unit, the pistons being mounted on a common piston rod which is attached to the draw carriage and the cylinders having means adapted to alternately releasably clamp the cylinders to the machine frame. The machine comprises a frame 1, Fig. 2 (not shown), supporting a die stand at one end, a carriage 10 bearing a workgripper 13, a second carriage 9 and two cylinder units 5 and 6. The carriages 9 and 10 are connected by piston-rods 7 and 8, each carriage having rollers running on the machine frame. The rods 7 and 8 are each formed with two pistons which are contained within the cylinders 5 and 6. Operation.-A workpieee 4 is threaded through a die at the right-hand end of the machine and into the gripper 13, the entire feed unit being positioned adjacent the die stand. The cylinder 5 is clamped to the machine frame by hydraulicallyoperated plungers and oil is admitted to the chamber 5b of cylinder 5 so that the pistonrods 7 and 8 and the carriages 9 and 10 are driven to the left, away from the die stand. When the carriages have travelled a predetermined distance, oil is admitted to the chamber 6e of the cylinder 6 so that the cylinder 6 also moves to the left, but at a greater speed than the cylinder 5, since the volume of the chamber 6e is smaller than that of the chamber 5b. When the cylinder 6 is almost in contact with the cylinder 5, it is also clamped to the machine frame and oil is admitted to the chamber 6b, so that for a short time the piston-rod 8 is driven by both cylinders. Cylinder 5 is then unclamped, and as the carriage 10 approaches the cylinder 6, oil is admitted to the chamber 5e so that the cylinder 5 moves rapidly to the left and overhauls the carriage 9. Cylinder 5 is then clamped to the machine frame again and co-operates with cylinder 6 in driving the pistonrod 8. The alternate locking and unlocking of the cylinders 5 and 6 is continued until the workpiece is drawn completely through the die. Both cylinders 5 and 6 are then unclamped and the feed unit is returned to the right-hand end of the machine by a roller mounted on the carriage 10, bearing on the machine frame and rotated by a fluid motor.

Title: Improvements in and relating to the electrolytic treatment of aluminium and the like
IPC: C25D11/04
Filed: 1943-09-28
Abstract: 599,188. Electrolytic surface treatment of metals. - PULLEN, A. N. D., and BRITISH ALUMINIUM CO., Ltd. Sept. 28, 1943, No. 15952. [Class 41] In a continuous process for the treatment of wire, tape or foil of aluminium or its alloys, tantalum, molybdenum, chromium, silver, iron, and particularly for the anodic coating thereof, current is applied to the wire by means of a liquid contact or path, while avoiding the use of contact rollers and the like. The invention is preferably carried into effect using a glass or other insulating tube for leading the wire into the treatment-vat, as described in Specification 573,983. Thus, in Fig. 1, a glass tube b having a constriction c at, or just below, the electrolyte level g, a vent f ,for gas, and inlet and outlet tubes d, e, for introducing and drawing off electrolyte, respectively, is provided with an enlarged section h containing an insoluble electrode i to which current is supplied by a lead j, and the wire a enters the tube in a non- electrified condition. In Fig. 2, the tube takes the form of two ebonite parts m, n, the latter having a constriction o, and a treatment box l to which electrolyte is supplied by the tube r. A helical electrode p surrounds the wire a and ends of the tubes m, n. The electrodes may be of platinum or other noble metal, or of platinum-coated copper. The treatment may be carried out with alternating current using twin electrode chambers electrically insulated from one another and with no "cathode" in the main bath, but direct current and a single electrode chamber containing a cathode may be employed. The liquid contact of the invention may alternatively be in the treatment bath. By the process of the invention, two coatings are formed, one in the tube itself and the other, in the opposite sense, in the main tank.

Title: Anti lock control system
IPC: B60T8/84
Filed: 1972-04-07
Abstract: 1378347 Anti-skid circuits TELDIX GmbH 7 April 1972 [22 April 1971] 16220/72 Heading F2F An anti-wheel lock control system comprises rotational speed sensors for the wheels on one vehicle axle, a first brake pressure control actuated by both wheels of the axle locking, a second brake pressure control actuated by locking of one of the wheels only, and a switch for switching from the first to the second control when the vehicle is subjected to transverse accelerations. The switch 11 comprises either an acceleration measuring device, e.g. a mercury switch, or is connected to the vehicle steering wheel and is actuated by angular positioning of the wheel. Sensors 1, 1<SP>1</SP> produce electrical signals proportional to the rotational speeds of respective wheels. The higher speed of the two is chosen as a reference value (speeds of other vehicle wheels may also be taken into account) and compared with the instantaneous speed of each wheel by comparators 6, 6<SP>1</SP>. The speeds for the reference value are stored in stores 4, 4<SP>1</SP>, for comparison at a comparator 5, by an actuating signal from each OR-gate 3, 3<SP>1</SP>, receiving a differentiated speed signal compared with positive or negative predetermined values at 2, 2<SP>1</SP>. Alternatively an RC circuit has a capacitor which charges to the higher speed value for transmission to the comparators 6, 6<SP>1</SP>. When the differences are above a predetermined amount, signals are passed to AND-gates 7, 7<SP>1</SP> which do not pass these signals if the acceleration of the wheels is positive. An AND-gate 8 transmits the signals to a pressure control valve 10 when both wheels provide high deceleration amounts. The switch 11 when closed allows a signal to pass to the valve 10 from an OR-gate 14 when either wheel provides the high acceleration amount. If, during braking from high speed, after a duration of brake release due to a signal from the AND-gate 8, one of the wheels locks, continued locking is prevented by a further signal being transmitted to the valve 10 through timing devices 15, 16, 17 and an OR-gate 12.

Title: Improvements in or relating to control apparatus for air and water craft
IPC: G01C19/00
Filed: 1940-11-08
Abstract: 547,555. Automatic course control apparatus. SMITH & SONS (MOTOR ACCESSORIES), Ltd., S., and MEREDITH, F. W. Nov. 8, 1940, No. 16232. [Class 135] An automatic course control apparatus for air or water craft comprises a rate of turn detector responsive to changes in aerodynamic or hydrodynamic forces set up by rate of turn, means for integrating the response of this detector to provide a central effect corresponding to the deviation from course and means for applying that effect to the appropriate controls for rectifying the deviation. In the arrangement shown in the Figure static pressure or venturi heads 10 mounted on the wing tips are connected by pipes 11 to opposed chambers formed by diaphragms 13 clamped to end plates 15. The diaphragms are connected by a tubular member coupled by lever and linkage mechanism 17, 19 to a repeating apparatus 20 such as that described in Specification 526,101, whereby movements of the diaphragms are converted into a variable air pressure in a pipe 22 without appreciably loading the diaphragms. The pipe 22 leads to a servomotor control apparatus such as that described in Specification 534,527 which produces a movement corresponding to the response of the diaphragms and to the time integral of the response. This movement is transmitted to the ailerons to maintain the course and stabilize the craft in roll in the absence of side slip. The above movement may be applied to the vertical rudder in place of the ailerons. The elevators are operated by a servomotor 30 with follow up 33 controlled by an air-speed detector comprises a dual pressure head 38 static head or the pressure in an aircraft cabin may be used as the static pressure datum. Sideslip of the aircraft is controlled by a side-slip detector comprising a dual pressure head 38 associated with a servomotor 39 in the manner described in Specification 520,176. This servomotor is connected to the rudder 40.

Abstract: 1303677 Anti-skid control systems; alarms; brake testing AISIN SEIKI CO Ltd and SHARP CORP 6 April 1970 [5 April 1969 18 April 1969] 16237/70 Headings F2E and F2F A vehicle anti-skid hydraulic brake pressure control system comprises a brake pressure reducing device 99 operable by a signal from a generator 10 in a subcircuit I of an electric circuit (Fig. 1), the circuit also comprising a subcircuit VI operable to produce a pseudo-skid signal (i.e. a pilot signal analogous to a skid signal) upon closure of a switch X which is connected with, for example, a starter motor switch, or a vehicle door to be operated simultaneously therewith, which pseudo-skid signal is fed to a junction d sub-circuit I at the outlet side of generator 10; the skid signal or the pseudo-skid signal will normally actuate the device 99, but in the event of the failure of the system to work in a predetermined manner as evidenced by closure of a switch Z equivalent to switch 140 will actuate an alarm such as a light 86 and render the anti-skid system non-operative. As seen in Fig. 3 the device 99 is connected between master cylinder 201 and rear wheel cylinder 208, and includes a diaphragm piston 213. Chambers 122, 218 are normally connected to vacuum source comprising the manifold of the engine, but on receipt of a signal at coil 31, a plunger 125 is moved to connect chamber 122 to atmosphere. This causes piston diaphragm 213 and a plunger 211 connected therewith to move to the left to close a valve 210, expand the volume of a chamber 206 and relieve the pressure on the brake cylinders 208. Connected with chambers 218 and 122 are switch units 138 and 140, respectively, which switch units have contacts closable by increase in pressure in their respective chambers, and closure of contacts 160, 161 is equivalent to closure of the switch Z in the electrical circuit. However, in the case of a pseudo-skid signal generated when there is insufficient vacuum the switch Z cannot be closed, and would therefore provide a false alarm signal: a vacuum-operated switch is therefore provided in the circuit. In Fig. 4 (not shown) is illustrated an alternative construction of the switch unit for chamber 122, and Fig. 5 (not shown) illustrates an alternative arrangement of the electrical circuit which provides for a pre-set safety time period in which pressure reduction must occur determined relative to the road surface.

Abstract: 1354026 Aerodynamic or hydrodynamic element NETHERLANDS APPLIED SCIENTIFIC RESEARCH FOR INDUSTRY TRADE & COMMERCE 24 May 1971 [29 May 1970] 16631/71 Headings B7A B7G and B7V An aerodynamic or hydrodynamic element 1, such as an aircraft wing or a propeller blade, has over at least a part of its length an endless belt 3 having means for moving the belt around the element and means for maintaining a lubricating film in the gap 11 between the belt and the element surface 2. The film is preferably the same as the ambient medium, such as air flowing in the direction 4, and is supplied under pressure through channels 7 and 8 and discharged through rows of openings 9 and 10 into the gap 11. On account of grooves 14, 15 in the surface 2 the major part of this air flows so as to rotate the belt in the direction 5, thus causing by the Magnus effect a force on the element normal to the flow direction 4. The grooves extend parallel to the flow direction, and the air can escape through holes 12, 13 into the interior 6 of the element, which is in communication, with the atmosphere. If a number of relatively narrow belts are used, these holes may be omitted and the air can escape laterally. In this case grooves 19 may extend at an angle to the flow direction, Fig. 5; this serves to prevent the belt moving laterally, as well as to rotate it. The element may also be used in water.

Abstract: 1472465 Standby systems; battery chargers PLESSEY CO Ltd 11 April 1975 [16 April 1974] 16659/74 Heading H2H Standby supply and battery charging apparatus comprises transistors arranged to be connected to a battery and a transformer connected to the transistors and arranged to be connected to the mains, the apparatus being such that when a connection is made to the battery the transistors operate together with the transformer in a transformer cotrolled pushpull mode to convert the D.C. voltage of the battery into A.C. voltage for a load, and when a connection is made to the mains then mains voltage is fed to the load and the transformer which then conducts A.C. voltage to the transistors which rectify this for transmission to the battery for charging. As shown, when the mains is not connected across terminals 1, 2, or it has failed, all switches are in the positions indicated and switch 9 is closed. D.C. from the battery connected between terminals 4, 5 is passed by transistors 18, 20 in opposite directions in the 2 halves of centre-tapped primary winding A of transformer T1 to generate A.C. in the secondary B which is passed to the load connected across terminals 1, 3. If the mains is present relays 8, 10 cause contacts 28 and 12 to close and contacts 14, 16, 22 to change over. The base-emitter junctions of transistors 18, 20 are both shorted and the base-collector junctions act as diodes to full-wave rectify the A.C. induced in winding A of transformer T1 to thereby charge the battery. Voltage limiting Zener diodes may be connected across the winding A.
