Abstract: 573,135. Two-part couplings combined with switches. CATALDO, J. B., and STILWELL, W. E. Dec. 9, 1943, No. 20590. Convention date, Dec. 5, 1942. [Class 38 (i)] [Also in Group XXXVII] A thermal cut-out comprises a three-legged bimetallic structure secured at its hub by a terminal rivet 24 and with the free end of its arm 23 engaging a dished disc 27 in the form of a three-spoked wheel, the centre of which is riveted to a shaft 30 and urged downwards by a spring 33. When heated, the strips 23 deflect upwards and throw the disc 27 overcentre with the rim bearing against a shoulder 37 on the body, thus separating silver-plating or contacts 28 thereon from similar contacts 26 on the strips 23. Rotation of a reset member 38 about fulcrum 38a raises shaft 30 and restores the original configuration of the disc 27, and subsequent release of member 38 allows spring 33 to remake the circuit. The cut-out condition of disc 27 may be indicated by a spring-controlled rod which is raised by the rim of the disc and projects from the top of the casing, Fig. 2 (not shown). The casing is arranged in the form of a screw plug fuse, but in Fig. 10 is incorporated in a double-ended adapter or coupling having plug pins 47, 51 and socket contacts 43a, 53a. The bimetal element 23 is mounted in a cup-shaped element 41 having coarse-threaded engagement with a plug-body 50 carrying the spring disc 44 and its supporting shaft and return-spring 33, the shaft having a pull-knob 46 for restoring the original configuration of the disc. The contacts 43a, 52a, and outer casing may alternatively be constructed to receive a flexible cable, so forming a simple plug element, Fig. 9 (not shown).

Filed: 1971-04-19
Abstract: 1328431 Slicing machines HOBART MFG CO 19 April 1971 [3 Feb 1970] 20959/71 Heading A4C A slicing machine comprises a base 10, Fig. 2, rotatably supporting an inclined circular slicing knife 15, a carriage 25 having a surface 34 extending parallel to the rotational axis of the knife, means supporting the carriage for reciprocating movement of the surface adjacent the knife, a guide rod 48 mounted on the carriage parallel to the surface 34, a gripping member 50, Fig.3, with prongs 56, 58 to engage material on the surface and supported by an arm 49 pivotally and slidably mounted on the guide rod, a lead screw 60 on the carriage extending parallel to the guide rod, and means slidably mounted on the guide rod cooperating with the arm 49 and engaging the screw 60 to effect lateral movement of the gripping member in response to rotation of the screw. The carriage is supported on a curved support arm 26 secured to a member 27, slidable on guide rods within an extended portion 22 of a housing 12 supported upon the base. An L-shaped tray 30 provides the surface 34 upon which material is gravity-fed to the knife, and has a boss 37 and flange 36 at its lower edge which support the guide rod 48 and screw 60 respectively. The guide arm 49 is straddled by lugs 87 depending from a yoke 86 with a cavity (88) Fig. 5 (not shown) for receiving the lead screw 60. A pin (90) passes through the yoke and is forcibly engaged with the screw by a spring (92), and may be disengaged from the screw by removing a cross pin (94). The screw 60 is engaged at either end by one way clutches 65 and 80, the lower of which 65, comprises a sleeve 68 surrounding a central core (66) keyed to the screw 60, Fig. 6 (not shown) the core having peripheral hollows engaged by rollers (69), and enclosed at one end by a plate 71 with an extending finger 72. In use the tray 30 passes through a feed stroke whereby slices of material are cut and caught on a gauge plate 42. As the tray returns the finger 72 of the clutch 65 is forced against a fixed abutment 108 and turns the screw 60 through a predetermined angle dependent upon the position of the abutment, whereby the gripping member and the material are moved a predetermined distance towards the knife. The carriage may then make another feed stroke, and the finger and clutch return under the action of the tensionspring, but the one way clutches do not allow the screw to turn to its prior position. The position of the gauge plate may be adjusted by a dial 45. The end prongs 58 of the gripping member are coated with plastic material of a greater length to the other prongs to prevent damage to the surface 34, The carriage, including the guide rod 48, screw 60, and gripping member, may be detached from the supporting arm 26 for clearing.

Title: Improved circuit arrangement for rectifier groups
Inventor: READ JOHN CARLEY
IPC: H02M7/06
Filed: 1959-06-18
Abstract: 948,127. Converting. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 2, 1960 [June 18, 1959], No. 20988/59. Heading H2F. To avoid excessive voltage drop in a rectifying arrangement employing parallel connected multianode rectifiers which have reactions in the anode circuits to reduce fault currents, and hgh speed D.C. circuit breakers in the cathode circuits, the reactors of the corresponding anodes of pairs of rectifiers are electromagnetically coupled to reduce the voltage drop when normal load current flows and each circuit breaker controls the cathode currents of rectifiers whose anode currents are not magnetically coupled. Rectifier pairs such as 1, 1<SP>1</SP>; 1<SP>2</SP>, 1<SP>3</SP>, are connected in parallel between three-phase supply 3 and D.C. lines 2, 2. Each rectifier has anodes such as 8, 88; 81, 88<SP>1</SP> connected in pairs such as 8, 8<SP>1</SP>; 88, 88<SP>1</SP> through centre-tapped reactors 9, 17, to the respective phase of supply transformer 4. D.C. circuit breakers such as 55b are connected in the cathode circuits of rectifiers such as 11, 13 taken from different rectifier pairs. The voltages induced in the two halves of reactor 9, 11 cancel during normal operation, but not when one of the anodes backfires, particularly in the period between the opening of the D.C. circuit breakers and the A.C. breaker 6. A multianode backfire is also limited.

Title: Improvements in rock drill grinders
IPC: B24B3/33
Filed: 1951-09-06
Abstract: 702,293. Grinding drills. AKTIEBOLAGET ATLAS DIESEL. Sept. G, 1951 [Sept. 21, 1950], No. 21056/51. Class 60 A rock-drill grinder comprises a base 1, a rotary grinding wheel 38 carried by a frame 13, 14, 15, 16 mounted to pivot on the base about an axis inclined at an angle to the axis of the drill-bit 6 which is clamped in a substantially horizontal position, and means for reciprocating the grinding wheel in the direction of a generatrix of its grinding surface, the surface ground on the bit being a surface of revolution produced about the pivotal axis of the frame. The bit may be clamped to a bench or in recesses 4, 5 in members 2, 3 attached to the base 1 by a beam 9, Fig. 3. An eccentric 12, on an arm 11 mounted pivotally on a swing- ing yoke 10, acts on the beam 9 to effect clamping. The beam 9 and yoke 10 are supported on standards 7, 8 provided with threads of different pitch to facilitate adjustment. The base member 14 of the frame carries a stop 21 against which the bit 6 is engaged and withdrawn a slight amount before being clamped to permit pivoting of the frame. The base 14 is secured adjustably to the table 13 of the frame by wing nuts and bolts engaging slots in the base, and the table is mounted to pivot on a bearing 19 about a bolt 20. The length of the member 16 of the frame is adjustable to vary the angle of inclination of the grinding unit which may be driven by a self-contained electric, or fluidpressure, motor 32 secured to a bracket 22, Fig. 4, mounted on pivots 23 on the member 15 and having a speed-control governor 33. The grinding unit is rocked about the pivots 23 to bring the tool into engagement with one of the edges 58, 59 to be ground by turning a handwheel 26 against the influence of a spring acting between the member 15 and the bracket 22. Further turning of the wheel 26, with the grinding wheel held stationary by the bit, displaces a plate 27, Fig. 5, located beneath the bracket, by an amount equal to the feed desired, against the action of springs 28 which expand to feed the grinding wheel. The motor 32, which may be controlled by a valve 55 in a conduit 54, also effects axial reciprocation of the grinding wheel 38 by co-operation between a cam-groove 52 in a driving sleeve 41, connecting the grinding-wheel shaft 39, and the motor shaft 43, and an axially-stationary follower 51 carried by a sleeve 50 driven at a different speed from that of the groove 52. Splines 44 are provided to drive the sleeve 41, and gears 45, 40, 47, 49 of which the number of teeth on the gear 46 may differ by one tooth from that on the gear 47, rotate the sleeve 50. A guard 37 is provided for the grinding wheel, and bellows 53 exclude dust from the head 34 which is prevented from rotating by a screw 35. Water is supplied to the grinding wheel along a conduit 56 and collects in a sump 57. In a modification (not shown), instead of reciprocating the grinding wheel in relation to its driving element, a portable grinding machine may be mounted on a slide reciprocated by a motor.

Abstract: 1,270,257. Reversible plough. R. H. RUTTERFORD. 22 April, 1969 [3 May, 1968], No. 21061/68. Heading A1B. A reversible plough comprises two sets of plough bottoms 38 mounted on a beam structure 10 which is pivotally connected to a tractor, the rear end of the beam being pivotally supported on a ground wheel bogie frame 17 on which at least one ground wheel 20 is pivotally mounted, the ground wheel pivot 30 being located to the rear of the bogie pivot 15 and the lock of the ground wheel being determined partly by the lock of the tractor and partly by the position of the plough bottoms. The bogie frame is deflectable by the servo motor 22 in response to the pump 53 which is actuated by the operation of the hydraulic motor 50 which tilts the cantilevers 27, 28 on which the plough bottoms are mounted. When the tractor is steered into a turn the shaft 19 and jaw 12 are turned relative to the main frame 10 which movement, via the linkage 44, 45, 33, 34, 26, and 32 causes the wheels to deflect to the opposite lock to that of the tractor. The positioning of the pivoting ground wheels behind the bogie pivot and the way in which the ground wheels are steered reduces the size of the headland where the tractor and plough are turned at the end of each plough run. The plough is lifted into a transport position by a combination of the tractor power lift linkage and the ram 29.
