Title: Improvements in and relating to pantograph type current collectors for electricallydriven vehicles
Inventor: WILSON FREDERICK
IPC: B60L5/32
Filed: 1954-04-23
Abstract: 760,425. Pantograph current collectors. ENGLISH ELECTRIC CO., Ltd. April 25, 1955 [April 23, 1954], No. 11797/54. Class 104 (3). In a pantograph current collector in which a restraining catch 35, when in the restraining position, prevents upward movement of the pantograph framework 10 when lowered the arrangement is such that operating means (for raising the pantograph) in its initial movement moves the restraining catch 35 from its restraining position. The pantograph framework is mounted on transverse shafts 11, 12 carried in bearings mounted in side plates 13 supported on insulators 14 mounted on a vehicle roof 15. Each side frame 10 has upper and lower links 10a, 10b articulated at 16. The lower links 10b are keyed to shafts 11 or 12 and the upper links 10a are pivoted to a bar 17 which carries the collector pans (not shown). A link 18 through levers 19 keyed to shafts 11 and 12 ensures movement in unison of the links 10a, 10b. The pantograph framework is raised by tension springs 20 stretched between roller chains 21 attached at 23 to scroll cams 22 keyed on shafts 11 or 12. When compressed air is admitted to a cylinder 29 a piston 28 compresses a spring 24 and at the same time moves a cross-head 27 carrying a cam 38 and side extensions 32. During the initial piston movement the framework is raised under the action of the springs 20. During the raising movement collars 34 mounted on rods 31, slidably mounted in the extensions 32 and connected to the framework 10 through lever 33 keyed to the shaft 12, bear against the extension 32. When the bar 17 engages the catch 35 upward movement of the framework 10 is arrested and the ends of the rods 31 slide relatively outward in the extensions until the catch 35 is pivoted by the cam 38 engaging a roller 39 to move the catch 35 against the action of a spring 37 out of engagement with the bar 17. The framework 10 then resumes its upward movement under the action of spring 20 until the collar 34 again abuts the extension 32 when further movement of the cross-head 27 allows the spring 20 to raise the framework to the fully raised position. To lower the framework 10 the cylinder 29 is exhausted and the spring 24 moves the cross-head 27 to the right of the Figure so that the cam 38 and roller 39 disengage and the catch 35 moves to its operative position and as the framework 10 is lowered the bar 17 strikes a sloping face 35a on the catch 35 to pivot the catch 35 against the spring 37 to allow the framework 10 to move to its lowered position.

Title: Device for balancing a grinding wheel during rotation
IPC: B24B41/04
Filed: 1958-04-14
Abstract: 834,742. Balancing grinding wheels. MOHRENSTEIN, A. April 14, 1958 [Oct. 8, 1957], No. 11867/58. Class 60. A device for balancing a grinding wheel 2, Fig. 1, during rotation comprises a balance weight 4 which is arranged within the hollow spindle 3 of the grinding wheel and mounted for movement in two directions perpendicular to each other and the spindle axis from a central position in which its centre of gravity S lies on the spindle axis, and two adjusting members 19, 20, Fig. 2, mounted on a frame 23 and operatively connected to the balance weight by intermediate members 28, 29 mounted for rotation in the spindle, each adjusting member being independently adjustable axially of the spindle to move the balance weight only in a separate one of the two directions. The balance weight, which may be of hard lead, is secured to one end of a screw 9, Fig. 1, having at its other end a ball 8 seated in a bearing disc 6 through which pass two rods 11, 12 disposed parallel to the spindle axis and offset therefrom at 90 degrees to each other. At one end the rods bear against slots 13 in the balance weight and at the other against a sleeve 29 and cylinder 28 respectively. Springs 14 situated diametrically opposite the rods urge the balance weight against the rods which, in turn, bear against the sleeve and cylinder, each of which is independ-. ently adjustable by means of concentric screws 19, 20, Fig. 2, disposed in a stationary housing and connected to the sleeve and cylinder, respectively, by a rod 26 and tube 24. Adjustment of the screws thus pivots the weight about the ball 8 in planes perpendicular to each other to balance the wheel. The wheel comprises a grinding ring carried on discs 1, Fig. 1, mounted on segments 60 having an internal curvature of spherical shape engaging correspondinglyshaped segments 59 provided with a tapered bore to fit the tapered end 39 of the grinding wheel spindle. Movement of the segments, relative movement between which is prevented by pins 69, in an axial direction by means of a nut 65 having a collar 66 releases the clamping pressure between the segments and the wheel to permit the wheel to adjust itself during rotation to a position without wobble, tapping of the nut 65 during rotation with a rubber hammer initially tightening the nut and axially displacing the segments to clamp the wheel and the final tightening being performed with a spanner when the spindle is stationary. In order that the degree of balance may be estimated, a resonator comprising a leaf spring supporting a pair of weights may be secured to the frame of the machine with the spring disposed transversely to the direction of vibration. The resonator is tuned to the grinding spindle speed by adjustment of the weights and the degree of balance may be indicated by a mirror, gauge or electric vibrometer.

Title: Improvements in or relating to electrical control systems for pumping installations
IPC: G05D9/12
Filed: 1965-03-23
Abstract: 1, 084, 886. Automatic liquid level control. WATFORD ELECTRIC & MANUFACTURING CO. Ltd. and I.M.E. AITKEN. April 4, 1966 [March 23, 1965], No.12314/65. Heading G3R. Detectors at two different levels in a liquid sump control electro-mechanical means to vary the rate of delivery of a pump removing the liquid so as to restore the surface of the liquid to between the two levels, and to further vary the rate of delivery in the same sense if the level is not so restored within a predetermined time. As described, when the level of, for example, water or sewage in a sump gets above or below electrodes arranged at two different levels a relay circuit is influenced to actuate an electrically driven step by step cam-operated switch controller which restores the level to between the electrodes by increasing or decreasing, as necessary, the speed, delivery or number of pumps emptying the sump. The relay circuit includes delay timing units so that if the level is not restored by one step of the controller, further steps take place at intervals to increase correction until it is effective. The intervals are less when decreasing the rate of pump delivery than when increasing it. If the electrical power supply fails, the controller moves to its zero position when power is restored so that the pumping load is initially at a minimum.
Patent GB-1013554-A (GB)
Title: Improvements in or relating to fiber optical devices of glass or like material
IPC: G02B6/08
Filed: 1964-03-24
Abstract: To form a fused glass fibre light conducting structure, a first group of fibres 20 is formed of material relatively non-absorbent to infra-red radiation and a second group of fibres 201 (Figs. 9, 12) or 46 (Fig. 17) is formed at least in part of material relatively highly absorbent to infra-red radiation, the fibres being arranged in compact side-by-side relationship in a bundle 44 with the fibres 201 or 46 of the second group so interspersed within the bundle that the relatively highly absorbent material is arranged in progressively increasing amounts and progressively closer relationship in radial directions towards a central axis 40 through the bundle and heat is then applied exteriorly of the bundle at a temperature sufficient to fuse the fibres together.  The greater absorbency of the inner fibres tends to equalize temperature distribution in the structure to give more <PICT:1013554/C1/1> material of low refractive index.  The fibres 201 are made absorbent to infra-red radiation by incorporating 0.5 to 1% by weight of ferrous oxide into the glass core 221 which may be flint glass, the cladding 241 being of crown or sodalime glass or the cladding may incorporate the ferrous oxide.  As shown in Fig. 12, four multifibre assemblies 42a with four fibres 201 as in Fig. 9, are surrounded by assemblies 42b having two fibres 201, then by assemblies 42c having one fibre 201 and finally by assemblies 42 having only first group fibres 20.  As shown in Fig. 17, the infra-red absorbing filaments 46 can be inserted between fibres 20 of assemblies 52, a similar arrangement to that of Fig. 12 giving inner assemblies with four filaments 46, then two, then one and surrounded by assemblies with no filaments 46.  To prevent light scattering, or stray light, special filaments 54 which are absorptive to visible light may be inserted between fibres 20 as in Fig. 17, but these filaments are preferably interspersed throughout the structure in substantially uniformly spaced relation.  Fusion is effected by assembling the fibres in a tubular member or a three-uniform fusion of the glass. Each fibre 20, 201 as shown is formed by a core as 221 of light conducting material of relatively high refractive index surrounded by a thin cladding 241 of <PICT:1013554/C1/2> <PICT:1013554/C1/3> sided block, the stacked fibres being compressed by a weight and fused between electric heating coils.  The multifibre structure 20, 201 or 46 may be formed by relatively large diameter fibres and the group of fibres drawn during heating to fuse the fibres.  In cathoderay tube face plates, the fibres are cut transversely into plates of the required thickness.
