Title: A lifting unit, more especially for conveying moulding boxes
IPC: B66C1/28
Filed: 1952-03-19
Abstract: 714,361. Load handling appliances; lifting dogs. BUDERUS'SCHE EISENWERKE. March 19, 1952 [March 19, 1951], No. 7130/52. Classes 78(3) and 78(4) A lifting and transporting unit on a track beam with pivoted load supporting arms comprises means for gripping and lifting and lowering and depositing an object in one reversal of operations. The lifting unit 5 runs on a track 3 and conveys moulds from a conveyer 2 to a moulding machine 1. The track has end stops 8 and 9 and a stop 15 which is engaged by a manually operated stop 14. The lifting unit is guided by rollers 10 attached to vertical supports. The grab arms 24 are detachably connected to members 20 pivoted to a cross member 22 and connected by links 19 to the ends of a cross bar 18. The cross member 22 has bolts 23 guided in the cross bar. The cross bar is connected to one end of a piston rod 17 of a hydraulic cylinder 16 supported in the middle of the unit. A source of compressed air 47 below the piston communicates with the upper part of the cylinder through a valve 46 and passages 49 and 50. A second valve 51 has a passage 52 communicating with the atmosphere. The valves are unseated by rotating levers 45 and 53. At the end of the conveyer 2 is a spring urged stop 32 connected by a linkage to two spaced vertical rods. In the normal position of the stop one rod 38 contacts one arm 41 of a bell crank lever the other arm 43 of which contacts lever 45 to unseat the valve 46 and to allow compressed air to enter the cylinder and depress the piston causing the arms 24 to descend and open, the movement being limited by stops 54a on the lifting frame. When a moulding box 27 strikes the stop 32 the linkage is operated to raise the rod 38 and close valve 46 and to lower the other rod to rotate the lever 53 and open the valve 51 which connects the cylinder to the atmosphere causing the piston rod to rise moving the arms inwardly to grip the box and then to raise it until the arms strike the adjustable stops 54a on the unit. The unit is then moved by hand or automatically to the moulding machine where a stop 55 contacts the lever 45 to open the valve 46 and so cause the piston rod to descend with the load which is then released and the unit can be returned to the original position where the operation is repeated. In a construction for manual operation the arms are pivoted to a cross bar having a projection guided in a vertical slot in the lifting unit. The unit pivotally supports two cylinders enclosing bored weights and oil. The cylinders are connected by links to extensions of the arms. The cylinders are connected by an endless member for simultaneous operation. Rotating the cylinders effects gripping the box and lifting which takes place under the effect of gravity. The weights may be adjusted by an external handle and the range limited by an end screw.

Title: Process and apparatus for calcining limestone
IPC: C04B2/10
Filed: 1976-02-24
Abstract: 1503263 Calcining limestone T A ROURKE 24 Feb 1976 [17 March 1975] 07147/76 Heading F4B In a process for the production of calcined lime, limestone pieces up to a size of 5 inches are fed into the top 42 of a refractory lined vertical shaft 30 which has a tapered base 33 and a horizontal draw feeder plate 35. A column of permeable material is supported by the feeder plate and combustion air from the inlet 41 is preheated as it rises through the material from the hopper 37 and openings 38. Fuel oil is injected under pressure into the column of material by spring loaded injection 43, 44, 45 and 46 in a pulsed sequence, and admixes with the upwardly flowing preheated air and ingites and burns with a long flame. Each injector receives a pulse of fuel lasting from 0À02 to 0À2 of a second at a rate of between 100 and 500 times per minute and this results in "lamellar flow" (as defined in the Specification) of fuel and air through the vertical shaft. Burned material 36 is drawn by a reciprocating ram 40 through the openings 38 into the cooling hopper 37 and discharges through an airlock 34.

Title: Multi-aperture magnetic core logic devices
IPC: H03K3/51
Filed: 1963-02-22
Abstract: 958,876. Magnetic storage devices. AMP Inc. Feb. 22, 1963 [March 8, 1962], No. 7241/63. Heading H3B. An exclusive OR gate comprises multiapertured storage cores 1, 2, Fig. 4, having major apertures 3 threaded by individual input windings X, Y and a common advance winding 2, and outlet minor apertures 4 threaded by a priming winding 5, an output winding 6, and an auxiliary winding 9, each common to both cores, the auxiliary and output windings being wound in the same sense as the priming winding through the outlet aperture of core 1 and the output winding being wound in the opposite sense to the priming and auxiliary windings through the outlet aperture of core 2. As described in Specification 899,366, the cores have clear and set states of magnetic remanence in which the flux forms a closed path around the major and outlet minor apertures respectively for storage of the binary values " 1 " and " 0." The flux around the outlet minor aperture is reversed in direction by a priming pulse applied to winding 5, before readout of a binary " 1 " is effected by pulsing the advance winding. An auxiliary load R d , Ld is connected to the auxiliary windings and has substantially the same impedance as the output load L L , L L , the inductor being either an air-cored choke or a bi-stable core. The provision of the auxiliary windings establishes a unidirectional pulse i D  through the auxiliary load whenever one or both cores in the set state are primed, and so loads the cores as to enable a wider range of permissive priming current to be used without adversely influencing the state of the cores by spurious loss or gain of data. The arrangement operates as an exclusive OR gate in that an output pulse icx, icy is produced if either core stores a binary " 1," whereas these pulses oppose and neutralize each other if both are switched. In an alternative arrangement, Fig. 5, the output load consists of a multi-apertured storage core 17 having an output winding Z, priming winding 26, and an advance winding 25 which is threaded through a bi-stable core 24 constituting the auxiliary load. Clearing of cores 18, 24 then takes place simultaneously in response to an advance pulse. In a modification each core 10, 11 is connected by separate transfer windings 22 to respective load cores and the auxiliary core consists of a further multiaperture core having an output winding. The arrangement then functions as an inclusive OR gate.

Filed: 1947-03-17
Abstract: 632,220. Automatic exchange switches. STANDARD TELEPHONES & CABLES, Ltd. March 17, 1947, No. 7301. Convention date, April 18, 1946. [Class 40 (iv)] In apower-driven telephone switch, a disc capable of limited rotation and held between friction surfaces on a wiper carriage tensions a control spring during its forward movement so that on removing the drive the wiper carriage is stopped by friction and centred by action of the control spring. As shown, a sleeve 9 supporting a wiper carriage 1 and a flexible gear 6 is rotatably mounted on a fixed shaft 5. A disc 10, having a forked extension arm, is supported freely on the shaft between a fixed lower plate 16 and an upper plate 25 free to move in a vertical direction only by a key and slot fitting. Friction discs 14 are interposed between the upper and lower plates and the disc 10, the whole being compressed by a helical spring 17. The flexible gear is normally depressed out of engagement with a continuously rotating gear 7 by a spring-biassed lever 21 which may be raised to allow the gears to engage by energizing the electromagnet 20. Initial rotation of the sleeve moves the disc 10 against the reaction of a control spring 15 until a fork 12 of the extension arm engages a fixed pin 11, whereupon the drive overcomes the friction between the disc and the moving sleeve and continues the rotation of the wiper carriage. During the driving period a spring- controlled pawl 18 moves idly over fixed ratchet teeth 19. When the drive is disconnected the wiper carriage is stopped by action of the friction discs, the sleeve assembly being then moved backwards by the control spring until the pawl engages the root of a ratchet tooth, in which position the wipers are centralized.
