Abstract: 1,066,269. Gear-cutting. DAVID BROWN GEAR INDUSTRIES Ltd. Feb. 28, 1966 [Nov. 28, 1964], No. 48479/64. Heading B3K. A hob slide comprises a rear part (11) (Fig. 3, not shown) adapted to slide reciprocally on a hob head (14), a middle part (12) pivotally mounted on the rear part so as to pivot about an axis (16) at right-angles to the face of the rear part (11), and a front part (13) which carries a hob spindle (17) at right-angles to the pivotal axis (16) and which is hinged to the middle part by hinges (19) having their axis parallel to the hob spindle (17). A motor (21), gear reducer (32) and variable-throw crank (22) are mounted on the middle part and are adapted by means of a variable length rod (24) to pivot the front part away from the middle part. The motor (21) is provided with a selsyn connection to the motor, not shown, which provides reciprocating motion of the hob slide so that in operation pivotal movement of the front part is synchronized with the reciprocal movements to crown the gear blank being cut. Limit switches may be provided on the hob head to limit the operation of motor (21), e.g. if it is desired to relieve only the ends of the teeth of the gear being cut. The hob spindle drive comprises a shaft (33) having a sliding bevel gear (34) in mesh with a bevel gear (25) mounted on the pivotal axis (16) of the middle part (12), a gear train within the middle part, a universal connection (27) (Fig. 2, not shown) between the middle and front parts and a worm (29) and worm-wheel (30). Various modifications suggested include: mounting the crowning motor (21) and reduction gear and crank on the front part; synchronizing of the motors electronically; the use of an hydraulic motor for the crowning action controlled by a tacho-generator driven in time with the hob slide, and mechanical means such as a cam or lever mounted on the hob head and arranged to impart the desired motion to the front part as a consequence of the reciprocal movement of the slide.

Abstract: 1,173,736. Starting prime movers. GENERAL MOTORS CORP. 17 Oct., 1968 [22 Dec., 1967], No. 49206/68. Heading H2H. A system for energizing the fuel pump of a motor vehicle or the like comprises means whereby the pump may be energized alone in order to replenish depleted fuel lines, may be energized together with the starter motor to start the vehicle engine, these energizations being supplied from the vehicle battery, and after the vehicle engine has started the pump is energized by the generator driven by the vehicle engine. With a manually operated switch 38 in the full line position shown in the Figure and a switch 46, operated by the vehicle transmission selector 48, open, a fuel pump 10 is energized by a battery 14, thereby to fill the fuel system and at the same time an ignition system 44 is energized. The switch 46 is now closed by moving the transmission selector 48 to the neutral position N, whereupon a starter motor 45 is energized to start the engine of the vehicle, thereby driving a D.C. generator 18. When the output of the generator reaches a desired value a winding 30 of a dual winding relay 24 is energized sufficiently to close contacts 26 and simultaneously the pump 10 is supplied by the generator 18 by way of a fuse 42 and resistor 43. The switch 38 may now be moved to the dotted line, or running, position, thus de-energizing the starter motor 45. With the contacts 26 closed the battery 14 is charged by the generator 18 by way of a second winding 28 on the relay 24, the winding 28 under these conditions, is arranged to assist the winding 30. Should the generator voltage fall below the battery voltage current from the battery will tend to flow in the winding 28 in the reverse direction, whereupon contacts 26 open the fuel pump 10 then receiving a reduced energization which is adequate to keep the engine running. However, should the generator output disappear, the fuel pump will be de-energized and the engine stopped.

Abstract: 499,955. Knitting wire. STEPHENS, F. C. April 29, 1937, No. 12277. Convention date, May 6, 1936. [Class 74 (ii)] A fabric is formed from helically preformed wire by inserting the partially flattened loops of a run into those of a preceding run and then bending them down into position to receive in their turn the loops of the succeeding rim. In the form shown the fabric is fashioned in a circular channel so as to emerge as a sleeve but it may be made in plane form and by direct manipulation. The wire helix is pulled out and wound on a spool 10 with its loops radial thereto and thence passes by and around guide rods 13, 15 the wire loops being thus twisted through 180‹ before entering the circular channel between a rotatable cylinder 16 and a fixed cylinder 11. As each loop on the preceding turn engages a cam 12 it is bent outwards to pass over, i.e. encircle the approaching loop after which it is bent downwards to extend the cylindrical formation. The inserted loop meanwhile continues its journey around the channel until in its turn it is deflected downwards by the cam to embrace another on-coming loop. In another construction the looped wire from the spool 10 enters the interior of a cylinder 30, Fig. 17, through a slot 34 and the operations of deflecting and bending the loops are performed by guides 36, 38.

[Also in Division G4] The apparatus described in Specification 1,099,601 is combined with an electromagnetic pre-selectable counter for the sheets which are separated, the counter including electric signal generating means operable by the passing of a sheet. The sheets, which may be currency notes, postal orders, or other documents of value, are separated sequentially from the bottom of a stack 20 by rollers 16, 24, and double-feed is prevented by fingers (30, Fig. 2) pre-set adjacent the roller 24 to form a feed gap. In the event of double-feed, detector rollers 48 set adjacent the roller 24 are lifted to operate a switch (52, Fig. 4) which de-energizes a magnetic clutch (40, Fig. 2) which is arranged between a drive motor 36 and belt drives to the separator rollers 16, 24. The roller 16 is stopped instantly by an electromagnetic brake 54. Each separated sheet passes beneath a curved plate 60 on a pivoted arm 58 to lift the arm, and the latter then operates a switch 64 which passes a signal to an electromagnetic counter (46, Figs. 3 and 4) of the type which is restored to zero condition. When a predetermined batch of sheets has been counted, the counter operates a switch in the circuit of a relay (44, Fig. 2), which in turn deenergizes the clutch (40). The separated sheets are forwarded by rollers 66, 68, driven from the motor 36, and by idler rollers 67, 69 on to a stacking platform 72, and an electromagnetic brake 70 on the roller 66 is responsive to the operation of the relay (46).
