Title: Improvements in or relating to material handling apparatus
IPC: C21D9/00
Filed: 1926-02-15
Abstract: 250,185. Brosius, E. E. April 3, 1925, [Convention date]. Charging and dicharging. - Apparatus for handling materials, applicable more particularly to charging and discharging furnaces, comprises load-handling means mounted on a truck 2 which travels freely over a supporting floor and has a pair of front wheels 3 and a single driving and steering rear wheel 10. The latter is driven through gearing 12 by an electric motor 11 and the steering is effected bv the hand-wheel 15 operating, through pinion gearing 13, 14, a stud shaft 7 projecting upwardly from a steering-frame. 8. To the front end of the truck is pivoted a bracket 18, Fig. 2, in which is mounted a peel 17 adapted to be rotated by an electric motor 20 supported on a rearward extension 19 on the bracket 18. The extension 19 is pivoted at 28 to the piston rod 21 of a fluid-pressure motor 22 pivotally mounted between arms 4 secured to the truck, and carrying an operators' seat 29. The outer end of the peel 17 is adapted for engagement with a charging-trough B which, after appropriate adjustment of the inclination of the peel 17 by operation of the motor 22, is inserted in the furnace 0 by the approach of the truck 2, and when in position, is inverted, to discharge the material, by operating the motor 20. In the modification shown in Fig. 3, the trough B is omitted and the motor 20 replaced by a fluid-pressure cyinder 36 adapted to extend or retract a rod 37 which is arranged within the peel 17<1> and secured to the arms 46, Fig. 5, of ingot-gripping tongs 47. The truck 2<1> carries counterweights 6<1> at the rear end to prevent tipping, and at the front a spring buffer 48 adapted to engage a plate 49 projecting outwardly from the front of the furnace. Fig. 6 shows a further modification for handling ingots, the peel 17 being in this case replaced by a slide 53 pivoted to the truck 50 at 51 and having a rear extension 52 which is connected to the motor 54 and has upstanding lugs in which is pivotally mounted a fluid-pressure motor 56. The rod 57 of this motor carries a U-shaped frame 59 adapted to embrace an ingot I, as shown, and withdraw it on to the slide 53 from which it mav be transferred to any desired position. A controller, operated by a pedal adjacent the operator's seat 29<1>, is provided for controlling the current supplied from an external source through a cable to the driving motor 11<1>, and the pressure fluid for operating the motors 22', 36, Fig. 3, is supplied by a flexible connection, to a tank 30<1> carried on the truck 2<1> and having separate pipe connections to similar four-way valves provided for each motor. Fig. 3 shows only the valve 39 for the motor 36, the operation of which is reversed by actuating the handle 42 connected to the rotary valve member 70, Fig. 9, which is so shaped that, in either position, the exhaust from the motor 36 passes off through the connections 43 and is delivered to the hollow peel 17<1> for cooling purposes, passages 45, Fig. 5, being provided for escape of the fluid through the peelhead 44.

Filed: 1930-02-08
Abstract: 347,776. Stoning fruit. FROVA, G., 5, Via Nicola Piccini, Milan, Italy. Feb. 8, 1930, No. 4328. [Class 28 (ii).] In a tool for extracting stones from fruit of the kind used in the machine described in Specification 254,305, [Class 28 (ii), Kitchen and like appliances &c.],i.e., a number of tongs-like cutting and gripping members which are thrust into the fruit seize the stone and withdraw it, the tongs-members 5 are pivoted at 3 in slots in a stem 1, and are opened and closed by a slotted flange 9 engaging the rearwardly extending shanks of the said members. The flange 9 is formed on a sleeve 11 which is slidable, during the operation of the machine, on the stem 1. The forward end of each member 5 is formed thusthe tip 7 is sharpened on the side remote from the axis of the tool, the section at this point being triangular so that a large gripping surface is presented to the stone. The gripping surface 10 is concave, preferably being elliptic, and leads to a cutting edge 6<1> directed towards the axis of the tool. The back 6 of the member 5 is thickened opposite to the edge 61 to give strength and rigidity, whilst the thickened back 6 merges into the cutting edge 7. When the tool is thrust into the fruit with the tongs open, the edges 7 make radial incisions around the stone, and when the tongs are closed, the edges 61 extend these incisions inwardly in the path of removal of the stone, which permits the extraction to be effected without removal of pulp.

Abstract: 844,800. Magnetic record apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 12, 1958 [Feb. 13, 1957], No. 4557/58. Class 40 (2). In a magnetic transducer device circuit means are provided to supply a continuous current to an eraze head winding to produce a magnetizing field of one polarity, said circuit means including control means operable selectively to cause said current to pass through a record head winding to produce a magnetizing field of opposite polarity. The device may be used for data storage as in digital computers where the signals comprise reversals of magnetic state. In the embodiment described with reference to Fig. 1, the eraze head coil 11 is connected in the cathode circuits of a bi-stable flip-flop circuit, so that whichever of the valves T 1 , T 2  are conductive as a result of input signals at 7, D.C. flows in the same direction through the eraze coil 11. Thus the intermittent current in record head coil 9 2  is in aiding relation in its effect on the record medium, while that of coil 9, is in opposition. The coil 9 2  may therefore be replaced by a resistance 23 as shown in Figs. 3 and 4. Fig. 5 (not shown), illustrates an alternative method employing a differential circuit in place of a flip-flop circuit.

Title: Process of increasing the refraction and hardness of imitation precious stones
IPC: C03C3/076
Filed: 1925-02-24
Abstract: 240,362. Gill, H. A., (Soc. d'Etude des Agglomeres). Feb. 24, 1925. Gems, artificial or imitation.-The refraction and hardness of imitation precious stones is increased by adding to a mixture from which, by crystallization or fusion, precious stones may be obtained, a quantity of zirconium. When the stones are to be produced by the slow crystallization method, the quantity of zirconium added is equal to that necessary to obtain a definite chemical compound capable of being crystallized, whereas, when the stones are produced by the fusion method, a less quantity than this is employed. Examples of suitable mixtures are set forth in the Specification. The precious stones may be formed by moulding the mixture into rods and fusing one end by a blow-pipe flame, or by fusing a pulverized mixture by a blow-pipe flame.
