Patent GB-1304923-A (GB)
IPC: G05D3/20
Filed: 1970-02-19
Abstract: 1304923 Walking beam conveyers NIPPON STEEL CORP 19 Feb 1970 [21 Feb 1969] 7941/70 Heading B8A [Also in Divisions F4 and G3] In a control circuit for a so called walking- beam type of conveyer, used for shifting ingots to a furnace, in which a piston drives the beam horizontally with a predetermined velocity characteristic for each stroke, the velocity characteristic can be altered when an ingot approaches the exit of the furnace so that it comes to rest at a predetermined position in relation to the ingot extraction equipment. In Fig. 3 a piston 1 operated by a servo-pump 9 drives the walking-beam (not shown) horizontally, and also a displacement encoder 4, the pulses from which are from the beginning of the stroke counted in a counter CA whose decoded output via stages 1-N provides a succession of N signals to accelerate the servomotor. The Nth signal remains constant for a predetermined number of displacement pulses thereafter, after which contact CR3 opens and the following displacement pulses are counted by a counter CB whose output via stages 1-N provides a succession of N signals to decelerate the servo motor and eventually end the stroke. The cycle is repeated until a photoelectric sensor senses an ingot approaching the furnace exit, whereupon contact CR4 feeds the pulses to counter CC, whose output via decoding stages 1-N is compared with the output of counter CA in a comparator 10. Upon equality or the output of counter CC being less than counter CA relay CR5" operates to control the servo-motor from the output of counter CC instead of counter CA, whereby if the photoelectric sensor operates during the acceleration period, the servomotor remains accelerating until the output of counters CA and CD are equal and then decelerates to a stop. If it is during the constant velocity period, control is immediately switched to the counter CD and if it is during the deceleration period deceleration proceeds normally and the piston is stopped only in the acceleration period of the next stroke.

Abstract: 557,426. Roads, runways, playgrounds &c. INTERNATIONAL BITUMEN EMULSIONS, Ltd., and JAMES, R. L. June 12, 1942, Nos. 8085 and 12032. [Classes 20 (iv) and 107] [Also in Group XV] In making roads, paths, playgrounds, aerodrome runways &c. by stabilization of the base with bituminous emulsion, 5 to 10 per cent of cement or lime or a mixture thereof is mixed with the soil in the form of a dry powder as a supplement to the emulsion. The cement, lime, or mixture thereof may be mixed with the soil by harrows, discs or a road mixer of the Woods or Barber Green pipe; water may then be added to bring the material to a fluid or semi-fluid condition, and a stable bituminous emulsion sprayed into the soil and mixed in by the same means, the mass being rolled after a suitable interval for drying. Alternatively, the emulsion is first mixed with the soil and permitted to dry for a suitable interval, the cement, lime or mixture being then added and intimately mixed before rolling. In an example, the soil is broken by ploughing and discing, sand added to reduce the lower liquid limit to 22 per cent and the loss on ignition to 3 per cent, 5 per cent of bitumen emulsion and water are mixed in, the whole is permitted to dry until just workable, about 7.5 per cent cement, lime or mixture is then mixed in and the whole is rolled. When required to resist heavy traffic &c., concrete, bituminous concrete, tar macadam, or asphalt may be applied to the surface as formed, or the surface may be sprayed with a bituminous &c. liquid and dressed with stone chippings or sand.

Title: Improvements in coin-freed vending machines
IPC: G07F11/54
Filed: 1932-03-18
Abstract: 387,163. Coin-freed articledelivery apparatus. BENKO, I., 2, Hermanngasse, Vienna. March 18, 1932, No. 8138. [Class 27.] The articles are stored in compartments of rotary drums T, Fig. 1, arranged above one another on a vertical shaft 3 driven by an electric motor E. The drums are rotated by the shaft through friction drives F, H but rotation is normally prevented by locking devices. When the articles of a particular drum are selected for delivery, a coin is inserted in a slot 40 and a press-key t corresponding to that drum is pressed in to release the drum, which is then rotated through the space of one compartment. The pressing in of one key t locks the others, in known manner, by blocks K sliding in a vertical tube n, the space between the blocks and the tube being just sufficient to allow the passage of the stem of one key at a time. The key t through a rod 22 actuates a lever 19, a nose 21 on which lifts a latch 10, Fig. 5, to release a double-armed escapement lever 9 controlled by a spring S. The ends 12, 15 of the lever 9 coact with dependent pins a on the drum normally to prevent its rotation in either direction. When the latch 10 is released, the spring S pulls the lever 9 so that the end 12 releases the pin a1, Fig. 5, and moves a switch arm 13 against a contact 14 to start the motor E. When the drum has rotated in the direction of the arrow through the space of one compartment, the pin a next after the pin a2 engages the cam end 15 of the lever 9 to restore this to locking position, thereby opening the switch to stop the motor. Coin-action, weight.-A key t cannot be pressed in until a coin is inserted. The coin dropping down the shoot 39, Fig. 1, hits the end 38 of a pivoted catch 35. This releases a lever 29, pivoted at 31, which is then pulled by a spring 37 so that a catch 28, pivoted on the lever, is moved from under the bottom block K23 of the column of blocks K in the tube n, and allows sufficient movement of the blocks to permit the passage of one key stem. A lug 24 on the block K23 engages an extension 41 of the lever 29 to return the lever to locked position. After release of the pressed-in key, the catch 28 again locks the column of blocks.

Abstract: 1,053,273. Measuring transistor characteristics PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Feb. 26, 1965 [March 3, 1964], No. 8379/65. Heading G1U. [Also in Division H3] A circuit arrangement for varying the operating point of a transistor 1 while maintaining constant dissipation includes a first potentiometer 3 which simultaneously but in opposite senses, controls both the operating voltage and current of the said transistor. In Fig. 1 transistor 2 acting as a constant current generator feeds a current whose value is determined by the tapping on potentiometer 3 to the transistor 1. The operating potential (-UcB1) is equal to the difference between the supply potential Uo and the potential formed by current Io passing through a portion of potentiometer 3. Variation of the tapping point thus alters the operating potential and the current in opposite senses. In Fig. 2 (not shown) a third transistor 6 of opposite conductivity type to transistors 1, 2 is inserted in the circuit to act as a current generator maintaining a fixed Io, the base potential of the transistor being maintained constant by a Zener diode 8.

Abstract: 526,514. Hydraulically-operated grinding &c. machine tools. CINCINNATI GRINDERS, Inc. March 18, 1939, No. 8697. Convention date, March 21, 1938. [Class 60] [Also in Group XXIX] A lever 46 movable about a pivot 68 to control relative movements of machine tool parts such as the movement of a grinding-wheel relatively to the work, is moved manually a short distance to rock a link 59 about an axis 51 into a position where a spring 55 can complete the movement of the lever 46, the rate of this movement being determined by hydraulic control means. The link 59 is made of two relatively slidable parts forced apart by the spring 55, one part being pivoted to a crank pin 61 on the lever 46 so that in the position shown in Fig. 7 the line of tension 67 of the link passes to the left of the pivot 68 but when the lever 46 is rotated clockwise this line moves to the right of the pivot 68 and the compression of the spring 55 causes the link to rotate the lever further, through the crank pin 61. Fluid is admitted to a cylinder 13 to actuate a piston 14 connected to a rod 10 fixed to the tool-carrier, under the control of a servomotor device comprising a plunger 16 controlling parts in a cylinder 15, the plunger being moved in one direction by a spring 17 and in the opposite direction by a lever 18 pivoted to the rod 10 and to a rod 20 moved axially by the rotation of a grooved cam 35 rotated by the lever 46. The groove comprises three inclinations corresponding respectively to a quick movement to bring the tool up to the work, a slow movement while grinding, and a quick movement after the piston 14 reaches the end of its stroke and for the purpose of opening the valves to increase the fluid pressure so as to lock the grinder while finishing off. The movement of the lever 46 is checked by a dash-pot comprising a piston 80 working in a fluid cylinder 69 and actuated by a rod 78 connected to the lever 46. The piston has perforations and the first part of the movement of the rod 78 takes up lost motion and then closes the perforations at that end. The piston stroke comprises three parts corresponding respectively to the three stages in the inclination of the cam 35. In the first, the fluid escapes through a valve comprising a plunger 88 fitting loosely in a cylinder 86, in the second, the passage to the cylinder is closed and escape is through a passage partially obstructed by the conical end of a screw, and in the third the piston opens a valve 106 to allow the fluid to flow around the valve.

Abstract: 829,346. Controlling tractors. INTERNATIONAL HARVESTER CO. OF GREAT BRITAIN Ltd. Jan. 22, 1958 [March 18, 1957], No. 8797/57. Class 79(5) A device for automatically disengaging the clutch on a tractor in the event of excessive draft loads, comprises an hydraulic valve 13 movable in response to the draft load and controlling the supply of fluid from the power lift system 16 to operate a clutch-disengaging plunger 4. The valve 13 may be coupled by a rod 18 to a draft responsive member 19 of the top link of the tractor three-point linkage and which is movable against the action of a spring 21. The plunger 4 disengages the clutch by rotation of a bell crank 1 of the clutch operating linkage which is normally held in the clutch-engaged position by a spring 10. In operation the clutch remains disengaged after the overload has been released due to the valve 13 blocking the return of pressure fluid and additional valve means may be provided to connect the plunger 4 to a return line. In a modification when the system is used under conditions of zero pressure in the powerlift cylinder 16 the device may be coupled to a part of the power-lift hydraulic system in which a sustained pressure is available. In further modifications the valve 13 may be incorporated in the draft-response control valve and may be actuated hydraulically by excess pressure in the power-lift system. Specifications 807,562 and 829,347 are referred to.
