Title: Improvements in or relating to balancing means for rotors
Inventor: WILKINSON WILFRED HENRY
IPC: F01D5/02
Filed: 1956-01-16
Abstract: 805,371. Balancing rotors. ROLLS-ROYCE Ltd. Jan. 11, 1957 [Jan. 16, 1956], No. 1485/56. Class 80 (2). [Also in Group XXVI] A rotor disc is balanced by means comprising a number of plugs each having a cylindrical portion to engage in one of a number of holes spaced around a circumference of the rotor and a flanged head extending transversely of the axis of the cylindrical portion and arranged to engage in a circumferentially extending groove on the rotor by rotation of the plug about its axis and each plug having a part adapted to co-operate with the rotor to prevent disengagement of the flanged head from the groove. The turbine disc 10 is provided near its periphery with an axial flange 14 from which projects inwardly a radial flange 15. The flange 15 is formed with a large number of drilled holes 16. A projection of the flange 14 beyond the flange 15 is formed with a circumferential groove 17. To balance the rotor some or all of the holes 16 have balancing plugs 18 comprising a cylindrical portion 19 which fits the holes 16 and a head 22, the axial thickness of which fits the groove 17. The head 22 is in the form of a circular flange 22 having two parallel flats 23 machined one on each side. The cylindrical portion 19 is engaged in the hole 16 with the flange 22 in the position shown in chain-dotted lines in Fig. 3, and when the plug is fully home it is rotated through a right-angle to bring the flange 22 into the groove 17. A pair of thin arcuate flanges 24 project from the flanged head 22. The ends of the flanges 24 are deformed to engage the radially inwardly facing surface of flange 14 to lock the plug against rotation. A notch can be provided in the recess provided in the flange 14 to accommodate the flange 24 and the plug locked by deforming the flange into the notch. In a modification, Figs. 4 and 5 (not shown), the head has only a single flat machined on it. In this case the plug is rotated through 180 degrees after insertion. The plug is locked in position by deforming an end of the flanges 24 to engage a flange on the rotor. The plugs may be of different weights which may be obtained by drilling the centre or by varying the length of the cylindrical portion 19.

Abstract: 769,354. Ventilation. BORG-WARNER CORPORATION. Jan. 18, 1955 [Jan. 19, 1954], No. 1494/55. Class 137  In an air-conditioning apparatus, a centrifugal fan in the casing of the apparatus causes air to flow upwardly from an air inlet opening through a heat-exchanger which is spaced from the casing and an internal partition which deflects the air through the heat-exchanger. As shown, the fan 50 draws air through a filter 55 and discharges it upwardly through the heat-exchanger 56 which is supported on rubber or like strips 57 on an inclined partition 32 carried by vertical and sloping partitions 24, 25. The heatexchanger may be as described in Specification 707,738 [Group XIII] and the air is discharged therefrom through a mesh 64 which arrests droplets formed in the exchanger when used for cooling. The front of the casing is closed by removable grille plates 72, 73, the top plate 73 having out- Jet louvres and the lower plate 72, which is hinged to the top plate, having inlet louvres. The outlet louvres are in middle and wing groups 79, 78, the middle group directing the main air flow upwardly, whilst wing louvres 78 direct the remaining air into two diverging streams with a slight rising tendency, A partition, at one side of the heat-exchanger, forms, with the casing, a chamber for a wiring panel, a lid being secured on the chamber by screws. The fan motor speed is controlled by a rheostat knob 67, high and low temperature aquastats 60 also control the motor, and a pipe 30 conducts condensate away from the heat exchanger 56. A number of units may be arranged in recesses around the walls of a room, and connected in parallel with a boiler or chiller, a pump forcing the hot or cold medium continuously through the heat-exchangers 56, the fan motors being started and stopped by the operation of the aquastats 60. The units may be modified by providing an additional discharge opening in the top plate 16, this opening discharges into a stack with a louvred delivery opening facing oppositely from the grille 78, 79. This enables the unit to serve an adjoining room.

Title: Improvements in or relating to electric pulse distributing apparatus
Inventor: BRANCH MAURICE CHARLES
IPC: H03K5/15
Filed: 1950-02-10
Abstract: 735,508. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. Jan. 23, 1951 [Feb. 10, 1950], No. 1713/51. Divided out of 735,501. Class 40 (4). [Also in Group XL (b)] An arrangement for producing pulses cyclically in a set of m x n leads comprises an m x n array of gates fed by two groups of m and n leads to which they are connected in different combinations, each gate opening when a coincidence occurs between the pulses on the leads to which it is connected. In one embodiment a multivibrator SV1, SV2, Fig. 6, delivers ¢ millisecond pulses at ¢ millisecond intervals to the amplifiers AV1, AV2 and clippers CV1, CV2, whose'output after further amplification in the cathode followers CFV1, CFV2 is applied to valve AV3 whose output consists of negative pulses which are clipped by rectifier DD2 and applied to the lead L2. The pulses are also applied to the phase inverter P1V to produce positive pulses on lead L3. Positive pulses are also fed to lead L1 from CFV2. The negative pulses on L2 step the sequence tube MCT1 to produce positive pulses on its 5 output leads in succession. When the fifth cathode is energized enabling potential is supplied to the valve CDV whose grid time constant circuit holds this potential long enough for the next positive pulse applied from L3 to cause the valve to conduct and suppress TV. Thus TV provides stepping pulses for the tube MCT2 at 1/5th of the rate of the pulses applied to L1, L2, L3. The cathodes of the tubes MCT1, MCT2 are connected to an array of 50 gas-filled valves such as TG1 in different combinations. When the valve is enabled on its two grids by potentials from the two stepping tubes it is momentarily fired by an anode pulse received over L1 to produce an output pulse on its cathode. In a second embodiment the co-ordinate array of gas tubes is replaced by an array of rectifier gates Fig. 4. For forty-nine of a master series of pulses fed over RR5 one or other or both of rectifiers DD2, DD3 are conducting to shunt the pulse, but on one pulse out of fifty, different for each of the leads 1 ... 10, both are baek-biased to permit the pulse to be fed to the output amplifier VV29, W30. Specification 681,330, [Group XL (b)], is referred to.

Title: Process for manufacturing a light alloy piston which has an annular cooling passage in its head portion
IPC: B22D15/02
Filed: 1975-01-15
Abstract: 1485731 Cored light alloy pistons KARL SCHMIDT GmbH 15 Jan 1975 [18 Jan 1974] 1757/75 Heading B3F In a process for manufacturing a light alloy piston with an annular cooling passage in the head portion, a permanent mould is filled with a molten piston alloy and a soluble core, with a lower density than the alloy, is forced into the molten metal by a holding device to the requisite location, and while the steel permanent mould is maintained at an elevated temperature by external heating, it is lowered at a controlled rate into a water bath so that directional solidification may take place. As soon as the casting has solidified up as far as the base of the core, the holding device is removed, the core remaining in position by being "frozen in". The cores are made from soluble salt mixtures, and are preheated to 450-500‹ C. prior to use to prevent gas evolution, and the moulds are heated to 450-600‹ C., preferably to about 540‹ C. by external gas burners, before lowering at 25-30 mm./min. into the water bath. After casting, the blanks are machined and pressed at about 500‹ C. using heated press tools, the cores being dissolved out subsequently leaving a cooling passage in the piston head.

Dies.-An attachment to a lathe or other rotary spindle machine for cutting the coiling-dies used in making metal hose comprises a work-holding spindle which is caused to be reciprocated axially to and from a stationary tool and rotated while advancing to the tool but restrained from rotation while receding, the attachment having a driving shaft connected to the lathe spindle. The attachment comprises a base 22 adapted to be secured to the lathe bed and supporting a bracket 28. The work-holding spindle 25, Fig. 3 is rotatably and slidably mounted in bearings 23, 27 on the base and bracket respectively, and a driving shaft 36 secured to the lathe spindle 17, Fig. 1 drives a cam shaft 29 through gearing 34. A face cam 33 operates to advance the spindle 25 -uniformly during one half of its revolution, through a rounded plug 38, and allow it to recede during the other half, the return movement being made positive by means of a rod 41 slidable through a hole in the bracket 28 diametrically opposite the spindle 25 and having a plug 43 and ball 44 respectively engaging the cam and a lever 54, pivoted at 48, whose upper end engages a thrust collar 55 on the spindle. The lever 54 is yoke-shaped and the two pivots 48 pass through straps 47 attached to the arms of the lever and through plugs 49 mounted in apertures of the base 22 and adjusted axially by screws whose heads are accessible through recesses in the sides of the base. The thrust collar 55 has lugs 56 bearing on the upper ends of the lever and is prevented from rotating with the spindle 25 by arms 59 embracing the shaft 29. A mutilated gear 40 on the shaft 29 engages a pinion 39 on the spindle 25, the construction being such that the spindle is rotated only during its advancing axial movement and is restrained from rotation during its retraction. The die produced by the apparatus consists of a spirally twisted segmental disc 67, Fig. 11, which is cut from a flat blank, and is counterbored at 69 on one face only. The blank is arranged on the spindle 25 so that its rotation will cease when the segmental gap 67<1> is opposite the cutting tool, and the latter is fed transversely for the next cut whilst the blank is receding axially. The blank is held during cutting in a recess 74, Fig. 8, in a face-plate 70 by means of screws 71 entering tapped holes in the blank, the plate 70 being held in a recess 26' in a second face-plate 26 by bolts 73. When one side of the blank has been cut it is removed from the face-plate 70 and attached to a similar plate having a spiral seating 74 to receive the formed side, the other side then being cut as before. Alternatively, a single face-plate 70 may be used having plain and spiral seatings on opposite sides. Specification 322,934 is referred to.

Abstract: 854,503. Shrimps, cleaning and shelling. JOHSSON, G. Jan. 21, 1957, No. 2156/57. Class 28(2) Headed shrimps 46, to be freed from their sand veins, and shells are each placed by hand in receptacle 42, Fig. 3 which open to drop each shrimp into one of the trays 50 with the tail projecting, the trays 50 being conveyed across a step by step rotated carrier 58. Tail clamps 62 draw each shrimp under rollers 66, Fig. 3a which press the shrimp underside into body clamp 64 which bring the shrimp back round against a rotated disc saw 72, Fig. 3b which removes the sand vein and cut into the shell. The clamps 64, squeezing the underside of the shell open out the cut into which enters a roller 82, Fig. 3c to press on and so loosen the body in its shell. The shrimp then passes over retracted spikes 90 which are then pressed up into the body Fig. 3d to hold it while the tail clamps 62 continue rotation to draw the shell away from the body. The spikes are then retracted Fig. 3e so that a stripper plate 86 frees the body Fig. 3f which is pushed sideways to fall down to one receptacle while the shell, freed from the tail clamps fall away into another receptacle. Continued rotation of the carrier 58 brings the clamps under a cleaning brush 102. The teeth of the slitting saw 72 increase in height from their leading to their trailing edges and decrease in thickness from their leading to their trailing edges. The saw 72 has flanges on each side to limit the depth of penetration. A jet of water and a brush may remove the slit debris.
