Title: Production of malleable iron and boron-ferrosilicon alloys therefor
IPC: C21C1/00
Filed: 1955-09-15
Abstract: Malleable iron is produced by introducing into a cupola charge of iron a ferro silicon-boron alloy containing Si 15-90 per cent, B 0.01-0.2 per cent, Fe and incidental impurities the remainder, this alloy being present in the charge in sufficient amount to add to the iron 0.0005-0.003 per cent B, melting the charge and casting and then heat treating the iron.  The iron after casting may be heated gradually to within the range 1600-1750 DEG F., held there for the required time and then cooled at a rate less than 10 DEG F. per hour through the transformation range to produce malleable iron free from pearlitic constituent.

Title: Calibratable thermostatic switch for thermal protection
IPC: H01H37/28
Filed: 1970-06-02
Abstract: 1,267,770. Temperature responsive switches. AMF Inc. 2 June, 1970 [13 June, 1969], No. 26485/70. Heading HlN. In a thermal switch the fixed contact 20 can, during manufacture, be turned about an axis perpendicular to, but displaced to one side of, the path of the movable contact 18 so as to adjust the operating temperature. The switch has a tubular metal casing 10 forming one terminal; a cable 28 is welded to an extension of the casing. One end of the casing 10 is closed and contains members 12, 14 which clamp the end of a snap acting bimetal blade 16. The blade carries the movable contact 18 at a point displaced from the axis of the tubular casing. The other end of the casing 10 is closed by an insulating block 30 in which the fixed contact 20 is embedded; a second cable 24 is welded to contact 20. The switch is set to the desired operating temperature by turning block 30 in the casing and then sealed with synthetic resin. In a modification (Figs. 3, 5, not shown) the block 30 is fixed and the contact rotates in it, both the axis of rotation of the fixed contact and the path of the moving being displaced, on opposite sides, from the axis of the casing which in this case is rectangular. This arrangement provides a greater range of adjustment.

IPC: H02K19/36
Filed: 1963-07-04
Abstract: 1,041,718. Dynamo - electric machines. LICENTIA PATENT - VERWALTUNGS G.m.b.H. July 4, 1963, No. 26573/63. Heading H2A. A cross-field machine has the commutator replaced by an arrangement of rectifiers connected to tappings on the distributed stator (armature) winding. Each tapping point is connected to two pairs of oppositely poled rectifiers to provide full-wave rectification for two independent circuits. The pair connected to the load conduct when the induced voltage is high; and those connected together (through a choke) to provide the cross-field excitation, are controlled to conduct when the induced voltage is near zero. The rotating pole structure of the machine is of cruciform shape and has control and armature reaction compensating windings on one arm only, the other arm being used to transmit the cross flux. The rectifiers may be silicon-controlled rectifiers and control signals are provided from an A.C. system synchronized with the machine rotation or alternatively, they may be derived from the stator winding through transformers.

Title: Improvements in or relating to radial sluice gates
IPC: E02B7/20
Filed: 1924-11-08
Abstract: 229,980. Ransomes & Rapier, Ltd., and Bowtell, W. J. Nov. 8, 1924. Sluice gates.-A radial sluice gate is constructed so that after it has been turned through a predetermined angle, it is raised as a whole by continued operation of the means employed to effect the radial movement. For this purpose the piers of the gate are provided with guide rails terminating at the lower ends in sockets or bearings for the pivots of the gate. The gate A, Fig. 1, is provided with an axle B at each end of which is mounted a roller C adapted to travel between vertical guide rails D secured to the piers E. Hoisting cables F are connected to the gate at G so that when the gate has been raised by rotation about its axis through a height approximately equal to its depth, the centre line of the cables passes through the centre of gravity of the gate. Further operation of the lifting gear will then lift the gate as a whole, the rollers C moving up the guide rails. Instead of a single roller at each side, a carriage H, Fig. 2, having two or more wheels C<1>, C<2> may be used. The gate is pivoted to the carriage H, and is provided' with an arm L which abuts against the carriage when the desired rotary movement of the gate is completed. Further hoisting then causes the gate and the carriage to turn about the upper rollers C<2> and to swing the lower rollers C<1> out of the .recess in the guide rails D. The gate and carriage are then raised vertically by further hoisting. In the modification shown in Fig. 3 a roller L<1> makes contact with one of the guide rails D when the desired rotary movement of the gate is completed. In a form for use in culverts, a number of rollers C<3>, Fig. 4, are mounted on the axis B of the gate and rest in a recess K in the wall of the sluice well. The frame of the gate is provided with rollers N adapted to engage guide rails P on completion of the rotary movement. In all cases the sockets on which the gate turns are preferably placed above the water level, and are so arranged that their sides are normal to a line passing through the centre of pressure on the gate.

Title: Device for handling a top distributor pattern for a foundry mould
IPC: B22C17/00
Filed: 1957-08-26
Abstract: 856,554. Moulding-machines. BUHRER, E. Aug. 26, 1957 [Aug. 28, 1956], No. 26864/57. Class 83 (1). Means for lifting a top distributer pattern 5 from a finished mould comprises clamping- means 45 for holding the pattern. Initially, the top distributer-pattern 5 is secured by pairs of clamps 45, actuated by fluid-pressure means 36, to an arm 33 in a vertical position. Fluidpressure means 40, 22, are then successively actuated to swing the arm to a horizontal position, and to lower it so that spring-pressed rods 6, projecting from the pattern, rest on a bottom pattern-plate 3. The clamps are then released and the arm lifted and swung away. When the mould has been compressed and the pressing- plate swung away, the rods 6 lift the pattern 5 clear of the mould so that it can be lifted and swung upwardly by the arm 33. Sand is shaken clear of the pattern as the arm hits a stop 16. The fluid-pressure means 22 has an adjustable stroke to determine the lowered position of the pattern, and may be checked in its movements by dashpots. Several such lifting-means may be mounted on a rotary table moulding-machine, and controlled automatically.
