IPC: C14B15/10
Filed: 1956-05-12
Abstract: 799,680. Cutting fur skins into strips. BREUNING, R. May 12, 1956, No. 14861/56. Class 31 (1). [Also in Group XXIII] Apparatus for cutting a fur skin into strips comprises a plurality of spaced disc cutters 32 secured to a shaft 30 which is rotatable in a direction opposite to the direction of rotation of a needle-carrying roller 54 the needles 56 of which pass between the cutters and through slots 78 in an adjustable guide plate 16 for the fur skin. The shaft 30 is rotatable by a motor 40 (not shown) and the shaft 52 of the needlecarrying roller is rotatable at a lower speed than the shaft 30, either by the motor through reduction gearing or by a hand wheel 51. The cutters are screened from the skin by means of a plate 21 provided with slots for the cutters. An adjustable elastic feed roller 25 is adapted to be rotated by the points of the needles 56. The cut strips are directed by the guide plate 16 on to a paper board 88 which is adapted to be fed forward by means of rollers 64, 74 provided on shafts 62, 72 driven from the shaft 52 of the needle-carrying roller. The cutting edges of the disc cutters are adapted to be sharpened by means of an adjustable brush 48 the bristles of which are preferably of synthetic material, e.g. nylon or glass fibre.

Title: Improvements in electric converting apparatus
IPC: H02M7/54
Filed: 1923-06-07
Abstract: 221,551. Calverley, J. E., and Highfield, W. E. June 7, 1923. Commutator switching - arrangements. - In apparatus for converting direct current from a system 4 at one voltage to a system 6 at another voltage by means of polyphase transformers having three sets of windings, two of which, 3, 5, are respectively connected to two groups of commutating gear 16, 13, rotated by a synchronous motor 11, as described in Specification 150,825, the third set of windings 20 is connected to the motor and supplies the power for driving the motor, white the magnetizing current for the polyphase transformers is chiefly supplied to the third set of windings by the motor, a separate source of polyphase current for driving the motor and supplying exciting current to the third winding being thus rendered unnecessary. The field' current of the synchronous motor is supplied from an exciting dynamo 12 and is regulated by adjusting a series resistance 24 or by varying the current in the field winding 23 of the dynamo 12 by means of a rheostat 22. The speed of the motor may be maintained constant with increasing load by adjusting the field excitation, as described in Specification 221,550. Automatic regulation may be obtained by means of an additional field winding on the rotor of the synchronous motor 11, this winding being placed in series with the direct-current mains 6 or connected' across a resistance inserted in these mains. The exciting dynamo way be run as a motor, from a battery 28, or from one of the direct-current systems, for the purpose of starting the apparatus.

Abstract: 703,657. Mining machines. JOY-SULLIVAN, Ltd., and MARR, D. June 16, 1952 [June 25, 1951], No. 14998/51. Class 68(1) In a mining machine one or more picks 1 are pivoted for movement about an axis longitudinal of the blocks 5 to which they are attached and the direction of movement of the chain, so that in the cutting position they are positioned at right angles to the plane of the chain but can be rotated into said plane to avoid obstruction by static parts of the machine. The pick is mounted at about its centre on a pivot pin 4 which is removably maintained in a bore in the block by a retaining pin 6, for example, passing through a co-axial bore in the pivot pin, the ends of the retaining pin being bent over to lie in recesses 6 in the block. The pick has at one end a cutting tip 2 and at the other a cam surface 3 which, on engagement with a cam surface 22 on the jib, urges the pick positively into the cutting position, a position which it normally takes up due to gravity when freely supported. Other cams 17, 18, 20 positioned on the machine and jib, as required, engage the pick to lift it into the plane of movement of the chain so as to be free from obstruction by the static parts of the machine.

[Also in Group XX] A time switch, particularly for prolonging the operation of a camera mounted in an aircraft after an associated gun has ceased firing, comprises motor driven cams 5, 6 which operate switches at predetermined times, e.g. as in Specification 642,878, the cams being fixed to a sleeve 7 which is loosely mounted on a shaft 3 and are only driven thereby when an electromagnetically-operated clutch is operative on de-energization of the magnet 8. The latter has a disc armature 9 which, when the magnet is de-energized, is pushed to the left, Fig. 3, by a spring 10 so as to engage teeth 13 on cam 5 and on a part 11 fast on the shaft. On energization of the magnet by closure of a pushbutton 25, Fig. 4, the armature is moved to the right and a spring 14 disengages the clutch so that a spring 18 can return the cams to their normal position as determined by an adjustable stop 23 and an abutment 22 on cam 6, the spring 18 having one end fixed to sleeve 7 and the other fixed at 19 to the casing. At the same time the gun (not shown) is fired and a relay 27 energized to close contacts 28 in parallel with a switch 15a operated by cam 5, thereby starting the camera 29. When the button 25 is released, the magnet 8 is de-energized and the cams are clutched to the shaft and the motor runs until its circuit is broken at the end of a time cycle at a switch 15 operated by a cam 6. The relay 27 is de-energized during this period, but the camera circuit is completed by switch 15a, being opened thereby at the end of the cycle.

Rolling. - A cooling-bed as claimed in the parent Specification for effecting the desired density of distribution of the sections, comprises a grating f, the undivided bars of which are rocked by a crank l and linked rod k so that the upper edge l of the grating is lowered and raised, the lowering of which lowers the sections to rest on and be moved continuously by a chain conveyor h. Uniform spacing of the sections is altered. by altering the time the sections are lowered in contact with the conveyor which is obtained by altering the initial slope of the bars f of the grating by turning the handwheel in to take up the rod k or by mechanical adjustment. For uniform distribution the upper edge e of the grating is parallel to the top i of the conveyor but to vary the distribution the edge e is arranged at a slope to the conveyor. Varying distribution in groups may be got by turning the handwheel m during working.
