Abstract: 844,139. Drawing wire. REHNQUIST N.B. Oct. 30, 1958 [Nov. 16, 1957], No. 34790/58. Class 83 (4). A wire-drawing machine includes at least one differential gear driving a greater number of drawing drums at the wire entrance side than at the take-up side, the first two drums being connected together so that the greater load at the entrance side of the differential gear produces the desired back tension. The drive for the drawing drums is transmitted from a transverse shaft 9 through a differential gear 6 and the drums 1, 2, 3 on the input side and 4, 5 on the take-up side are driven through differential gears 7 and 8 respectively, drums 1 and 2 being interconnected and driven by one shaft of the differential gear 7. The drawing drums are of progressively increased diameters so that all the differential gears are more heavily loaded on the input side, thereby causing back-tension on the wire between the successive stages. In the form of machine shown in Fig. 3, the output shafts of the differentials 7 and 8 are arranged concentrically and are driven from a motor 11 and gear-box 12, through the differential 6. The wire A passes first through a die 1<SP>1</SP>, round drum 1, pulley 14, through die 21, round drum 2 which is connected with drum 1 and then round pulley 15 to the die 3<SP>1</SP> and drum 3. It then passes through die, 41 to drum 4 and round pulley 16 to die 51 and drum 5. The arrangement of the coaxial drums 1, 2, 3 and their drives is shown more clearly in Fig. 4. A shaft 18 carries an upper member 18<SP>1</SP> to which is secured the plate 19 of the drum 3 and a tubular shaft 17 which rotates around the shaft 18 has an upper member 17<SP>1</SP> to which is bolted the second drum 2. The drum 1 is bolted to the underside of the drum 2. To assist setting up the machine, the drums may be locked by means of a tooth 34 carried by the plate 19 and engageable with a toothed ring 35 on the top of the plate 17<SP>1</SP>. a sleeve 21 associated with drums 1 and 2 has a connection 24 for the supply of lubricant to a distributer 25. Oil shields 26-30 are provided. A modified form of machine has three drums only, two interconnected drums on the input side driven directly from one output shaft of the differential 6 and a single drum on the takeup side driven directly from the other output shaft of the differential 6.

Title: Fluid apparatus
Inventor: PANISSIDI HUGO ANTHONY
IPC: F15B21/12
Filed: 1961-09-29
Abstract: 972,860. Punching machines. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 29, 1961, No. 35308/61. Heading B4B. [Also in Division F1] A fluid-operated system, which may be used to operate a punching machine, comprises a member 11, 12, Fig. 1, moved in a first direction by an input pulse supplied through a conduit 10 from an input 21, and a pulse delay means 26 which absorbs the increase in pressure of the pulse until the member is moving in the first direction, the pressure in the delay means then acting to reverse the direction of movement of the member. As described, the member 11, 12 consists of a differential piston having two parts, part 12 being connected by a rod 13 to a punch 14 co-operating with a die 15 and stripper 16. Part 11 is connected by the conduit 10 to the inlet 21, which may be at a pressure of 650 p.s.i. or exhaust 22, which may be at a pressure of 50 p.s.i. by a valve 18 movable against a spring 19 by an eccentric 20. The pulse delay means consists of a chamber 26 connected by a port 25 to one side of the piston 12,'and by a throttle 27 to the conduit 10. In operation, as the eccentric is rotated and the valve 18 moved the inlet 21 is connected to the conduit 10 and a pulse of pressure moves the piston to the right so that the punch 14 engages the die. The pressure in a chamber 24 caused by the movement of the piston passes into chamber 26 and initially, because of the throttle 27, is lower than the conduit 10. Shortly afterwards, however, because of the differential areas of the piston, the pressure in chamber 26 exceeds that in conduit 10 and acts to return the piston to its initial position. In an embodiment for operating three or more rods 13a, 13b, 13c, the actuation of one of the rods causes the actuation of the second, and so on. High pressure fluid is connected to inlets 21a, 21b, 21c and when a pulse occurs in conduit 10a to move piston 11a, 12a and rod 13a, valve 18b is moved to connect inlet 21b to conduit 10b to move piston 11b, 12b and rod 13b. Consequent action of valve 18c effects movement of piston 11c, 12c and valve 18a to again move piston 11a, 12a, the operation continuing until the supply is disconnected from the inlets 21a, 21b, 21c. The valves have a loose connection to the rods and are moved rapidly during the operative stroke by collars 40a, 40b, 40c on the rods but return at a speed determined by springs 19a, 19b, 19c and the rate of flow of fluid through valves 50a, 50b, 50c which permit unrestricted flow in one direction and restricted flow in the other. In another embodiment, overlap between the operations of the pistons is prevented by providing additional chambers, each of which is pressurized during the strokes of its associated piston and is connected to the next piston to be operated when its associated valve has returned to its initial position.

Abstract: 617,856. Gas turbine plant. GRYLLS, S. H. Nov. 29, 1946, No. 35512. [Class 110 (iii)] A gas turbine plant for driving a road vehicle comprises a turbine 14 coupled to a compressor 12, and a turbine 16 driving the road wheels 20A through reduction gearing 19. Between the two turbines are a free-wheel clutch 42, shaft 43 and reduction gearing 46, such that the compressor turbine 14 normally runs independently of the power turbine 16, but, during retardation, when the speed of turbine 14 has fallen sufficiently the power turbine commences to drive it and it, therefore, acts as a brake on the system. The compressed air receives heat from the exhaust of turbine 16 in a heat-exchanger 22 and passes through swirl openings 28 into a combustion chamber 25. Secondary and tertiary air enters the chamber 25 through holes 29, 31. The main fuel supply through pipe 65 is controlled by a throttle valve 64 and supply for slow-running passes a governor-controlled valve 69 which is opened when the speed falls near to the minimum self-driving speed and thereafter brings the compressor set to its slow running speed. A continuous supply to a pilot jet 67 goes by pipe 68.

Abstract: 729,906. Capsules for bottles. BRUUN, O. J. Dec. 22, 1953, No. 35638/53. Class 125 (3). Also in Group XVI] A cup-shaped capsule of soft metal foil is impressed with one pattern of indentations on the outer surface of the capsule and with a different pattern on the inner surface, so that, when nested one inside another, separation is facilitated. The invention is described with reference to a capsule having pleated side walls as disclosed in Specification 629,430. The indentations are in the form of narrow grooves. In the form of Fig. 1, the grooves 2a on the outer surface are arranged in line with the generatrix of the side wall and those 2b on the inner surface, in two intersecting parallel sets forming a cross pattern. In the form of Fig. 2 the outside grooves 2c are arranged at an angle so as to intersect the fold lines 1 of the pleats and the inside grooves 2d have a wavy form. When the capsules are nested, the tops of the ridges of the inside pattern bear on the tops of the ridges of the outside pattern so that the air space between them is increased and the exposed lip of each capsule is greater. This facilitates separation e.g. in a device as described in Specification 689,530. The capsules may be patterned between a die having a groove pattern 4, Fig. 5, on the inside and a punch having a groove pattern 3 on the outside.
