Title: Improvements in or relating to the sharpening of lawn mowers or like cutting machines
IPC: B24B3/42
Filed: 1929-07-22
Abstract: 336,025. Paul, J., and Sinclair, J. July 22, 1929. Lawn-mowers. -A grinding attachment for lawn-mowers and like machines, which allows of the blades being sharpened without reversal of the direction of rotation, comprises a bar of abrasive material, such as carborundum, independent of the ledger blade and carried by a frame which is detachably mounted on the ground roller supports. The abrasive material, 10, Fig. 5, is fixed by adjustable clamps 12 to a plate 11, end flanges of which are notched to engage and pivot on the bolts 17, which secure the ground roller posts 18 to the cheek plates 19, or on pins 20, projecting from plates 21 which have slots 22 to adjustably engage the bolts 17. The plate 11 is adjusted about the pivots 20 by means of a block 23 which is connected to the centre of the plate and projects backward, its rear end being pivoted to a bolt 24 which passes through a cross bar 26. The ends of the bar 26 are supported by brackets 28, Fig. 7, each of which has a projection 28<b> to engage the slot in the corresponding groundroller post 18, a hole 28<c> to receive the bolt 17, a hole 25<a> to receive a bolt passing through the slot 22 in the plate 21, and a forked part 28<a> to receive a bolt 27 which detachably secures the bar 26 to the bracket. A spring 29 surrounds the bolt 24 and the inclination of the plate 11 is adjusted by means of a nut 31 on the bolt. The arrangement, is such that the grinding attachment can be removed from the brackets 28 which are left in position on the machine.

Abstract: 423,229. Fusible cut-outs. WESTING- HOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A.-(Assignees of Rawlins, H. le G. ; 710, Coal Street, Wilkinsburg, Pennsylvania, U.S.A.) Aug. 1, 1934, No. 22430. Convention date, Aug. 25, 1933. [Class 38 (i)] The fusible (e.g. bismuth - lead) link 67 of a cut-out is situated in an arc passage and is heated by a separate heater which normally closes one end of the arc passage and which, in the embodiment shown, is a disc 75 of carborundum in contact with a metallic ferrule 44 forming a terminal of the re-fill element and with a copper rivet 71 which conducts heat to one end of the fusible link. The disc is metal-plated at the contact surfaces. The other end of the fusible link is connected to a rod 47 which is under the tension of a spring 19, when the re-fill portion of the cartridge shown in Fig. 2, is in position in the permanent portion, Fig. 1. The fibre casing 41 of the re-fill element is lined with boric acid, the lining being provided with a supplementary passage containing a wire secured to the rod 47 and in sliding contact with a further wire which is normally insulated but carries current when an arc is struck as the result of fusion of the link. This arrangement adapts the cut-out for operation on light as well as heavy overloads. The lower end of the casing 41 is strengthened by a fibre plug 57. In a modification the heater is shunted by a fuse.

Abstract: 1,178,945. Calendar watches. ETA A. G. EBAUCHES-FABRIK. May 10, 1968 [May 11, 1967], No.22432/68. Heading G3T. A calendar watch comprises a date ring 11 having teeth 16, a stem 4 adapted to co-operate with a date setting lever 2, the stem being displaceable axially into separate winding, hands adjusting and date adjusting positions and a spring- loaded tongue 15. The tongue is pivoted on a lever 14 by a pin 28 and the lever, which is biased in a clockwise direction by a spring 24, is pivoted on the plate 1 by a pin 13. In the innermost or winding position of the stem 4, a nose 20 of the lever 2 engages a lug 18 of the tongue to hold the tongue out of engagement with the teeth 16. In the central or hands setting position of the stem, the lever 2 is rotated so that the nose is withdrawn from the lug 18 and the tongue springs upwardly into engagement with the teeth 16. When the stem is pulled to its outermost position (as shown) an arm 26 of the lever 2 rotates the lever 14 in an anti-clockwise direction thereby causing the tongue to abut the face 16a of a tooth 16 and index the date ring forward by one day.

Title: Voltage regulator
IPC: G05F1/20
Filed: 1973-05-14
Abstract: 1432607 Automatic control of voltage R W BECKWITH 14 May 1973 [15 May 1972] 22822/73 Heading G3R An A.C. voltage regulator for an electrical distribution system sums a signal dependent upon the system voltage with two signals proportional to the system current, one in phase with, and the other phase shifted relative to, the current, and controls the voltage (e.g. by tap changing) if the summation is outside a selected range. As shown, the signals are obtained from transformers T4, T 1  and T 2  and summed with a reference value by operational amplifier Q 1 . This amplifier includes a diode D4 and feedback thermistor Rt I to provide a temperature independent half-wave rectifier, summer and line drop compensator. The output of amplifier Q 1 , which is proportional to the rms value of the sensed voltage, passes through a double-T filter and is compared in operational amplifiers Q3, Q4 with pre-set limits, set by potentiometers R28, R29 across a stabilized supply from voltage regulator Q2. If outside these limits, as indicated by light emitting diodes L 1 , L 2 , a timer T 10  including operational amplifier Q 6  is started to turn on transistors Q 8 , Q 1  0 . If the voltage is still outside the limits when the timer T 1  0  times out i.e. transistors Q 8 , Q 10  are turned off, the signal from operational amplifier Q3 or Q4 passes via Zener diodes D 11  or D 12 , turning on triacs Q 1  1  or Q 1  2  until the voltage falls within the pre-set limits. The triacs may control a motor driving a tap changing transformer, buck or boost autotransformer, induction voltage regulator or the field of an A.C. generator. The load may be an arc furnace.

Abstract: 772,103. Forging. KOHLER, F. Aug. 10, 1955 [Aug. 20, 1954; June 13, 1955], No. 23037/55. Drawings to Specification. Classes 83 (2) and 83 (4). A method of hot-upsetting a head on the end of a steel rod which has been hardened by heat treatment or cold working, comprises inserting the end of the rod in a die and therein heating and upsetting the end in such a manner that the heating to forging temperature is performed rapidly and briefly whereby the mechanical strength of the hardened steel rod is not impaired. The invention is applicable in particular to high-tensile steel re-inforcing rods used in making pre-stressed concrete structures, these rods being cold-twisted before heading whereby they are hardened. The end of the rod after being inserting in the die, is locally heated by a torch or by high frequency induction heating, and is then upset, for example by hand tools. The die and also the part of the rod adjacent the heated end, are preferably cooled by water. An example is given for the upsetting of cold-twisted concrete re-inforceing rods.

The slots 31 in the handle ends are tapered to engage the tapered or flaring ends of the studs 19 by a sliding movement, and the handle, ends are guided by a U-shaped bead 33 on the, bottom of the guard-plate, the closed end 34 of the bead limiting the sliding movement of the handle. The taper of the studs is less than that of the slots 31 and the parts of the guard engaged by the handle are inclined in the direction of movement of the handle so that the ends of the handle bind securely on the studs. The end of the guard adjacent the end 34 of the bead 33 has a lip 35 to protect the thumb or finger of the user from contacting with the blade in assembling the parts. The teeth of the guard may be arranged nearer the blade edge at one side than the other by disposing the openings in the guard slightly away from its longitudinal axis.
