Title: Improvements in or relating to eccentrically actuated presses with strip feeding means
IPC: B21D22/00
Filed: 1962-12-05
Abstract: 1,029,139. Metal strip feeds. KONINKLIJKE METAALWARENFABRIEKEN V/H. J. N. DAALEROP & ZONEN N.V. Dec. 5, 1962 [Dec. 6, 1961], No. 45912/62. Heading B3W. An eccentrically operated press whose tools 4, 5 are mounted in a carrier 1, has means 34 for feeding strip material 24 transversely of the working stroke of the tool 5 and means 21 for moving the tools in the feed direction of the strip during their working stroke. Upper tool 5 is mounted on a vertical slide 6 driven by an eccentric pin 9 working in a block 8 slidable horizontally but vertically guided within a slot 7 of the slide 6. The entire carrier 1 is also movable horizontally through a link 18 by an eccentric 21 which is adjustable for varying the stroke. Strip 24 is fed at a uniform speed by feed rollers 34, 35 driven through a one-way coupling 37, Fig. 2 (not shown), by a variable speed drive unit. In order to give exact movement of the strip 24 and the carrier 1 during the actual working stroke, a pinion 40 on the drive shaft of feed roller 35 meshes with a rack 41 secured to the carrier 1 whereby the feed rollers are moved bodily to the left with the carrier, against spring restraint 31 during the actual working stroke. Alternatively a second oneway coupling may be provided between the feed roller and its drive so enabling the rack to rotate this roller faster during the working stroke. In another embodiment, Fig. 5 (not shown), for a multiple tool press, one tool is driven by a pair of eccentrics 59, 60 interconnected by gearing, and another tool is driven by eccentric 61. The carrier 51 is moved horizontally with the strip 63 during the pressing stroke by a link 58 adjustably connected at 72 to a lever 64 mounted on a vertically adjustable pivot 66 and driven through links 77, 70 by a crank-pin 71. The link 77 carries a pair of rollers 75, 76 running in a cam slot 73 whereby the movement of the carrier is constant and equal to the strip feed during the actual working stroke. The carrier may move in slides or on rollers or may be mounted on a vertical pivoted arm or on a parallelogram mechanism.

Abstract: 1,195,113. Washing machines. DANFOSS A.S. 12 Oct., 1967 [14 Oct., 1966], No. 46547/ 67. Heading D1A. [Also in Division G3] A supervising unit, for a programme controlled washing machine, includes an amplifier to the input of which sensors are selectively coupled by the programming system as required for the control of successive stages of machine operation. As shown, a programme stepping system 12 controls a magnetic valve 13, for the supply of water to a washing drum, a motor 14 for driving the drum, a pump 15 for draining and a water-heater 16. The mechanism 12 also selectively connects an amplifier input 6 to terminals 18 providing data indicative of the completion of a programme stage. Terminals 18a-d are allocated to temperature valves, determined by the transfer of a tapping point along series resistors 21-25 of which resistor 21 has a negative temperature coefficient and senses an actual temperature. The resistors form, with a centretapped secondary winding 20, an A.C. bridge, the error signal from which is applied to the in put 6. Terminals 18c-h are connected to liquid level electrodes 32-35 co-operating with the tube wall 31 to apply through a resistor 30 a voltage from the winding 20 to input 6, which indicates through an electrode 32 the level to which the tub is drained during a pumping operation, electrode 33 the water level for moistening, electrode 34 washing level and an electrode 35, the level for rinsing. The tub electrode 31 also cooperates with an electrode 37, arranged at a low level in the tub, which during heating can short-circuit the N.T.C. resistor 21 through an arrangement comprising transistors 38, 39. An high level electrode 36 is connected to input 6 to protect against overflow by interrupting the programme. The amplifier, having the input 6, comprises transistors 4, 5, supplied from a secondary winding 2 through a rectifier 3, and initiates the stepping of the mechanism 12. It is stated that the electrodes may be connected in a bridge circuit and resistors 22-25 shunted to change the desired temperature setting.

Filed: 1974-12-09
Abstract: 1482637 Digital data storage NATIONAL RESEARCH DEVELOPMENT CORP 9 Dec 1974 [5 Oct 1973] 46595/73 Heading G4A] A digital information storage arrangement includes a data field 1 and an inverse field 3; to determine whether a word (e.g. "10") inserted by a key 5 is stored in data field 1, the word is used to address inverse field 3, the content ("1") of inverse field 3 at the addressed location indicating the address in data field 1 where the keyed-in word ("10") is stored. If the same word is notionally stored in more that one location of data field 1 a tag column (8, Fig. 2, not shown) may be associated with data field 1. The inverse field 3 stores the highest address of the word in data field 1; this location in data field 1, however, stores the next lower address in the data field 1 which notionally or actually stores that word and the tag is set to "1" to indicate this. The lowest address in such a chain actually stores that particular word and the tag is set to "0". In an alternative embodiment data field 1 stores words as in Fig. 1, inverse field 3 again stores the highest address of each word in data field 1 and the data field 1 is associated with a third, linkage, field (9, Fig. 3, not shown), at each location of which is stored. the next lower address in the chain of data field addresses storing that word. The chain of addresses and/or the stored word may be read out sequentially from the linkage field and/or data field. A fourth field may be included to indicate the number of entries of each word. The arrangement may use a plurality of data fields and associated inverse and linkage fields (Fig. 5, not shown), each word being split into bytes each of which is stored in a respective data field. Each byte of a keyed-in word is then fed to the respective inverse field, and a least value unit may be used to shorten the search-time for each multi-byte word. Two such arrangements may be used, with one least value unit, for sorting long words. To store long words using one such arrangement overflow bytes of a word may be written in the following address and these maybe associated with an "overflow" character.

Patent GB-470388-A (GB)
Abstract: 470,388. Two-stroke engines. DAIMLER-BENZ AKT.-GES Nov. 11, 1935, No. 31126. Convention date, Nov. 10, 1934. [Classes 7 (ii) and 7 (iii)] A two-stroke engine cylinder is scavenged by an inner axial stream y and an outer helical stream x one of which streams is induced by the mass exit of the exhaust, whilst the other is forced in under pump pressure. The streams enter by ports m, l, and leave by exhaust ports o at the opposite end of the cylinder. The ports are formed in a piston c in which the main piston d slides and which is acted on by the same impulse, the pistons being respectively connected to the crank-shaft by rods and eccentrics e, a<2>, and a connecting-rod and pin a<1>. The piston c compresses the charge, previously admitted through ports h, in the spaces P<1>, P<2>, the throttling effect of the clearance g increasing during the stroke until it is transferred by passages K and tangential ports to the combustion chamber H. The piston c has a slight lag on the piston d ; air is drawn through the ports m from the atmosphere by the mass exit of the exhaust gas. A liquid-fuel admission device may inject fuel through a port to the piston c but alternatively the engine may work as a mixture engine. The Specification as open to inspection under Sect. 91 comprises also connecting the ports m to the pump compression space P<2>, instead of to the atmosphere. The piston c may act simply as a pump piston, or be replaced by a sleeve valve. This subjectmatter does not appear in the Specification as accepted.

Abstract: 1478822 Extruding elongate metallic bodies METALL-INVENT SA 25 Nov 1975 [5 Dec 1974] 48304/75 Headings B3A and B3P A method of forming an elongate body by extruding a cast mass 28 from a receiving chamber 1 through a die 19 comprises reducing the volume of the receiver 1 so as to extrude a portion of the cast mass through the die, increasing the volume of the receiver and adding molten material to the receiver at a location remote from the die 19 and repeating these steps so that further portions of the east mass are extruded and the volume of the cast mass is sustained by the addition of molten material. At the beginning of a work cycle, the inner space of the receiver is filled with molten metal which has been supplied through a funnel 2. An opening 12 is then closed by a water cooled stopper 23 and the molten metal fuses on to the cast mass 28 as it cools to a plastic state. A heating element may be provided to keep the bar at extrusion temperature. A die holder 14 together with the die 19 are advanced into the receiver 1 so as to extrude a part of the mass 28 through the die, the holder 14 being formed with a member 17 so that the bar and die holder move together as the holder is withdrawn. The stopper 23 is then raised to allow further molten metal to enter the receiver and the extrusion cycle is repeated. The receiver 1 may be provided with a bush (7), Fig. 3 (not shown), into which the molten metal is supplied, the bush being formed with cooling channels (8) and having provision for heating coils (11) in its outer periphery. The stopper 23 is fitted with a heat-resistant fire-proof cover 25 and its end may project beyond the cover so that it enters the opening 12 during the extrusion step, Fig. 8 (not shown). Alternatively a stopper (41) may extend right through the opening and the bush (7) into the cast mass (28), Fig. 9 (not shown), in which case it is slidable within a heatresistant cover (40).

Abstract: 1292595 Road traffic detectors GEC-ELLIOTT TRAFFIC AUTOMATION Ltd 14 Nov 1969 [14 Oct 1968] 48610/68 Heading G4Q Vehicle detection apparatus comprises a looped conductor mounted in or on a sheet of flexible material which serves to protect the conductor from damage when laid upon a road surface. In one arrangement, a perforated foil conductor 1, in the form of a loop open at one end, is moulded within a neoprene mat 2. Electrical connections 3 are made between the ends of the foil 1 and a cable 4 which extends to detector equipment 5. Depending upon the frequency employed in the detector equipment either the magnetic or the electrically conductive character of a vehicle may be employed. In the frequency range 30-60 kHz, the eddy current effect is predominant and a decrease in measured impedance occurs in the presence of a vehicle. The detector equipment performs a differentiation of the impedance signal and thus is unaffected, after an initial response, by, for example, the parking of a car near the loop. However, it may in some circumstances be desirable to indicate the presence rather than the passage of a vehicle and in that case an absolute measure of the impedance is made. An alternative arrangement employs separate neoprene sheets which are bonded together so as to sandwich the conductor 1. In a further alternative, insulated wire may be used for the loop. In a typical application, the invention is used on a temporary basis, for example, in connection with portable traffic signals to control traffic movements about road works and temporary obstacles, portable traffic counters or speed measuring equipment. The mat formed by the flexible sheet(s) is either simply laid upon the road or semi-permanently fixed to it by bonding.
