Title: Improvements in and relating to dynamoelectric machines
IPC: H02K23/20
Filed: 1948-11-22
Abstract: 664,254. Exciting dynamo-electric machines. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 22, 1948 [Nov. 22, 1947], No. 30320/48. Class 35. A D.C. machine, which when used as generator has its P.D. inversely proportional to the load and when used as a motor the torque developed is proportional to the shaft load, has a main field winding 12 separately excited and an auxiliary field winding 14 fed from auxiliary brushes 7, 8 through a rectifier 13. The brushes 7, 8 are in quadrature with the main brushes 5, 6. When the machine is used as a generator the m.m.f.'s of the main and auxiliary field are arranged to be in opposition, so that as greater load is supplied from the load brushes 5, 6, more P.D. is produced across the brushes 7, 8 and therefore more current flows to the auxiliary winding 14 via the rectifier 13 with the result that the net pole flux is reduced in inverse proportion to the load current. As a motor, the m.m.f.'s of the main and auxiliary fields are arranged to be cumulative and, as greater load is applied to the motor greater flux and torque are produced. Due to the rectifier action the auxiliary field winding will always oppose the main field winding in the case of the generator whether it is generating or motoring and will always assist in the case of the motor whether it is motoring or generating. The poles 3, 4 are preferably notched as at 9, 10 in order to leave gaps to provide sparkless commutation at the brushes 7, 8.

Title: Control system for a glass moulding machine
Inventor: DENMAN ROBERT RICHARD
IPC: C03B7/16
Filed: 1956-10-06
Abstract: 798,016. Glass working. OWENS-ILLINOIS GLASS CO. Oct. 6, 1956, No. 30529/56. Class 56. A system for controlling the flow of glass 16 to a moulding unit 11, 17, is provided with an air-blast 33 which, on actuation, will divert the flow of glass away from the moulding unit in response either to operator control or to functional failure of the moulding unit. The operator-actuated control may be, and the control actuated by functional failure of the moulding unit is, additionally arranged to stop the drive of the moulding unit. Pressure air from pipe 32 may be admitted to pipe 47 by the operator pushing valve rod 46 to the right ; pipe 47 leads to a cylinder 7 from which it passes through pipe 54 to nozzle 33 when it is permitted to do so by a cam 50 working in synchronism with the flow 16. Stopping of the drive to the moulding unit is effected by the operator swinging lever 48 counterclockwise which has the effect of cutting off air-pressure from pipe 32 (until then acting through pipes 35, 36, 37 and cylinders 2, 3) to the right-hand end of hydraulic cylinder 5 to enable a spring in this cylinder to exhaust the hydraulic pressure that until then actuated the moulding unit. Lever 48 and valve rod 46 are so inter-connected that movement of the lever counterclockwise also moves valve rod 46 to the right, whilst movement of the lever clockwise is not communicated to the valve rod (which can, however, be moved by the operator in either direction when the lever is in the limiting clockwise position shown). Functional failure of the moulding unit operates cam mechanism 58 .. 61 to exhaust air pressure from cylinders 3, 4, the latter of which contains a piston secured to a plate 42 which operates the lever 48 and valve rod 46 with the same effects as are produced by the actuation of lever 48 by the operator.

Abstract: 238,762. Marks, E. C. R., (Hauck Manufacturing Co.). Dec. 22, 1924. Liquid-fuel supply; vaporizing-apparatus.-The supply of fuel and air to a liquid-fuel burner 20, delivering into the heating chamber 15 of a portable forge, is effected by an electrically-driven fan 28 which supplies air through a pipe 47 to a space 48 above an inclined partition 35 extending between one wall of the tank 25 and a vertical partition 36 terminating just above the bottom of the tank. Perforations 50 are provided in the wall 36 to permit air from the space 48 to enter the main part of the tank to effect the supply of fuel through the pipe 26 to the burner 20, a pipe 27 serving to supply air for atomizing and combustion purposes. The burner tip 22 is rotatable by means of the ring 21 to regulate the air supply. The filling tube 38 is so disposed that the level of oil in the tank 25 cannot exceed that of the lower end of the partition 35 which is perforated at 51 to allow any leakage to drain back into the tank.

Abstract: 1450972 Percussive tool G KLEMM [trading as INGENIEUR GUNTER KLEMM SPEZIALUNTERNEHMEN FUR BOHRTECHNIK] 11 July 1974 [11 June 1974] 30824/74 Heading B4C An hydraulic percussive tool comprises a driving piston 11 and a control piston 23 the working piston 11 during its movement on the return stroke uncovering a series of throttled ducts 25, 26, 27, 28 which control the movement of control piston 23 which in turn gradually decelerates piston 11 thus preventing severe shocks. The piston 23 comprises a liollow sleeve acted on by springs 31, 34. In operation pressure medium enters by a duct 13 and passes by ducts 19, 15 to both sides of piston 11 but causes the piston to move downwardly due to the larger area at the upper side of piston 11. Control valve 23 is held down by pressure on its surface 56. When the ducts 25-28 are cut off by the piston 11 the pressure therein falls and the pressure on surface 56 falls allowing the valve 23 to rise and connect the upper area of piston 11 to exhaust duct 21 by an annular ring 29 in piston 23. As the piston 11 rides control duets 25-28 are gradually uncovered which allows valve 23 to move slowly downwardly due to build up in pressure on surface 56 and hence the pressure builds up slowly above piston 11 to produce gradual cushioning. A spring loaded valve 14 is provided to pass incoming air to an accumulator 43 to cause gradual movements therein and prevent rupture of the membrane 44 therein.

Filed: 1964-08-04
Abstract: 1,039,478. Hydraulic apparatus. W. P. DUNPHY. Aug. 4, 1964 [July 29, 1963], No. 31256/64. Heading F1P. In an hydraulic remote control system comprising a master cylinder 10 Fig. 1 (not shown) divided by a piston 12 into hydraulic chambers 66, 68 connected by lines 52, 50 to chambers 124, 120, Fig. 3 (not shown) into which a slave cylinder 30 is divided by its piston 32, automatic re-synchronization of the pistons 12, 32, is effected when the slave piston 32 is at its datum point e.g., mid position and as the master piston is approaching its mid position by the pressure fluid displaced by the master piston being made to by-pass the slave piston which is thus held stationary until the master piston reaches its mid position. The slave piston 32 has radial passages 138 which at the mid position connects line 52 and chamber 124 with a bore 128 in the fixed rod 34 over which the slave piston 32 slides and which bore 128 is connected by a line 54 to a bore 80 in the fixed rod 14 over which the master piston 12 slides. The bore 80 opens into an annular recess 88 and is closed by a shoulder 94 of the piston 12 when in its mid position. The shoulder is flanked by a chamber 90 connected by a port 96 to a reservoir space 95 and by a chamber 92 connected by bores 98, 102 and check vlaves 100, 104 to chamber 68. In operation and assuming the master piston is being moved to the right towards its mid position whereas the slave piston is already at its mid position, fluid forced from chamber 66 through line 52 into chamber 124 leaks through passages 138 and recess 134 aligned therewith, bore 128, line 54, bore 80, recess 88, chamber 90, port 96, space 95, bore 98, part check valve 100 into chamber 68. The slave piston thus remains in its mid position until the master piston reaches its mid position when it closes recess 88. Subsequent movement of the master piston in either direction results in corresponding movement of the slave piston. In the event of the master piston being moved to the left towards its mid position whilst the slave piston is already at its mid position, fluid is forced by master piston 12 from chamber 68 past valve 104, through chamber 92, recess 88, bore 80, line 54, bore 128, passage 138 and line 52 to the suction chamber 66 of master cylinder 10. In a modification a rotary cylinder block is formed with six cylinders arranged parallel to and spaced from the axis and pistons therein are reciprocated by a swash plate; by-pass means being located in the closed end of the cylinder block. The apparatus is intended to effect hydraulic steering of a ship.
