Abstract: 810.019. Sintering machines. METALLGESELLSCHAFT A. G. Dec. 10, 1957 [Jan. 8, 1957]. No. 38429/57. Class 82(1) Green pellets formed from fine-grained material are sintered by heating a layer of pellets in a moving pallet having grate bars which are supported on hollow beams through which a cooling medium is passed to minimize damage to the bars by overheating. As shown, a pallet mounted by axles 3 on rollers 1 to run on tracks 2, has grate bars 6 fitted to T-shaped flanges 9 of the hollow beams 7a which are cooled by the passage of air flowing in opposite directions through adjacent beams. The air is supplied by the same blowers that are used to create the suction in the chamber 10, and the heated air may be used as preheated air applied to the pellets during sintering.

Abstract: 1,025,874. Automatic voltage control. ROBERT BOSCH G.m.b.H. Oct. 22,1962 [Oct. 21, 1961], No. 39807/62. Heading G3R. A voltage regulator for a generator having a field winding 14 comprises a power transistor 23 in series with the field winding, a control transistor 24 responsive to output voltage for switching the power transistor, and a circuit for protecting the power transistor against overload. The protection circuit includes the series combination of a resistor 41 and a diode 40, acting as a voltagedependent resistor, connected in parallel with the field winding 14 and the emitter/collector path of the transistor 23; a potentiometer formed by a temperature compensating resistor 42 and a resistor 43 is connected across the diode 40, and the junction P of resistors 42,43 is connected over a diode 44 to the base of transistor 24. The arrangement is such that when an excessive current passes through a resistor 45 in the emitter/collector circuit of transistor 23 the increased voltage drop across this resistor gives, together with the voltage drop established by the diode 40 across resistor 42, an effective total voltage which renders diode 44 and transistor 24 conducting, whereby transistor 23 is switched off and protected from damage. A double diode may replace the two diodes 40, 44 (Fig. 3 not shown), and the circuit may include a third transistor (Fig. 4, not shown).

A valve closure means, e.g. a piston 118, is displaceable within each chamber 12 on the establishment of a pressure difference across the means and is adapted to co-operate with a corresponding valve seat formed around the outlet 16 when the pressure difference exceeds a predetermined maximum. A fluid by-pass 104, 100 extends between the inlet and outlets and a valve 121 is provided for selectively directing fluid either into the chamber 12 or through the by-pass. The by-pass may be connected to the outlet end of the chamber through one-way valves. In the construction shown a passage communicates through a one-way valve 126 with a reservoir. The valve 121 may comprise a screw 42 having a conical tip 44 and a waisted portion, the screw being mounted in a housing 10 and the position of the screw in the housing determining the connections of the valve. The piston may be latched in its forward sealing position (Figs. 3, 4, 5, not shown).

Equipment of relatively great length, such as timber, rails and the like is raised and lowered in a pit shaft in a container which is pivotally suspended eccentrically beneath a mine cage so as to be horizontal at the loading and unloading station and vertical during movement in the shaft. The container comprises a main section B, pivoted about a horizontal axis on a suspension device C which is detachably mounted on rails 24 secured to the bottom of the mine cage 45. The right-hand end of the section B is open and the left-hand end is adapted to be closed by a hinged section A which constitutes the base of the container during movement in the shaft. At the stations, the container rotates between the horizontal and vertical positions under the control of pivoted arms having hooks 37 adapted to engage a projection 11 on the container. In operation, the load is pushed into the container on a trolley 46 and the hinged section A is closed and locked. With the hook 37 engaging the projection 11, the cage and container are raised, thereby causing rotation of the container to the vertical position, Figs. 11, 12 (not shown) and disengagement of the hook. As the container reaches the unloading station, it is engaged by a similar hook and thereby rotated to a substantially horizontal position, Figs. 13-15 (not shown) in which the container is slightly inclined to allow the trolley to run out of the container on to rails at the unloading station. Stops are provided to limit rotation of the container.

Apparatus for the lapping of knives comprises two rotatable members 5, 11 provided on their surfaces with a rib or ribs of rectangular crosssection intermeshing to such an extent that the angle at which the surfaces meet is equal to the blade angle of the knives to be lapped, one member being substantially disc-shaped and the other member substantially cone-shaped. The disc is supported by engaging means 4 on the shaft 3 of a motor 2, and the cone 11 is carried by bearings 9, 10 on a shaft 8 carried by a bush 7 on the upper end of a column 6. The shaft 3 and a bevel gear 14 on the cone 11 have pins 16, 17 whereby the members 5, 11 can be adjusted so that the axes of the members intersect. The gear 14 meshes with a gear ring 15 on the disc 5, the surface of which is formed with four equidistant inwardly spiralling ribs 18 interengaged with a single helical rib on the cone. The interengagement of the ribs makes an angle corresponding to the angle to be formed on the edge of the knife 22 to be lapped which may be reciprocated in the direction of its cutting edge. An abrasive in the form of a liquid or paste is supplied, the surplus abrasive passing through channels 21 into a vessel 20. The apparatus may have more than one cone cooperating with the disc so that a plurality of knives may be sharpened simultaneously.

Abstract: 1466377 Internal shoe drum brakes; wear adjustment GIRLING Ltd 29 Aug 1974 [29 Aug 1973] 40701/73 Heading F2E An abutment assembly is adapted to be disposed between adjacent ends of a pair of brake shoes of an internal shoe drum brake, a doubleended hydraulic actuator being positioned between the other shoe ends; the abutment assembly comprises tappet assemblies 6, 7 having respective abutments 8, 16 for engagement with the shoe ends, the abutment 8 having a recess 9 containing an elastomeric deformable member 10 engaging a piston 13 which is operatively connected to the abutment 16 via a collar 19 and a spindle 15; the end portion of the member 10 engaging the piston 13 is of smaller area than the end portion engaging the abutment 8 whereby when the brake is applied with the drum rotating in the forward direction (i.e. from right to left in the drawing) only a part of the force is transmitted from the abutment 8 to the abutment 16. As shown, the recess is in the form of a blind bore 9 which slidably receives a sleeve 12 whose inner end abuts a shoulder 3 formed in the housing 1 of the assembly. The piston 13 which is slidable in sleeve 12 has a hole 14 for release of air which would otherwise be trapped between the piston 13 and the member 10 during assembly. The collar 19 is carried by the spindle 15 which has a threaded portion 17 received in a threaded bore 18 in the abutment 16. The spindle 15 co-operates with a gear 20 of an adjuster mechanism, and the gear 20 and the spindle 15 are keyed together for relative axial movement. When the brake is applied with the brake drum rotating in the forwards direction an abutment load is applied to abutment 8 by the trailing edge of the adjacent shoe and the abutment 8 is urged leftwards and forces the deformable member 10 into the sleeve 12 to push piston 13, collar 19, spindle 15 and abutment 16 leftwards-however the force transmitted to abutment 16 is less than that applied to abutment 8 due to the force reduction effect of squeezing member 10 into sleeve 12. When the brake is applied with the drum rotating in the reverse direction the full force is transmitted through the abutment 16 through spindle 15, collar 19, piston 13 and sleeve 12 to the abutment 8. An assembly in which force reduction is achieved in both directions may be utilized wherein two deformable members are provided, one housed within each abutment.
