Abstract: 374,579. Boring engine cylinders &c. SCOTT, J. A., 418, Rotherhithe New Road, Bermondsey, London. April 28, 1931, No. 12539. [Class 83 (iii).] Boring-heads.-In a device for the internal grinding or boring of engine cylinders, a short grinding-spindle 12 is adjustably mounted in an eccentric bearing in the grinding-bar 10 and is driven from a separate driving-shaft 24 extending axially through the grinding-bar, and for trueing up a bore prior to grinding, a cutting tool attachment 48 may be secured to the lower end of the grinding-bar. The tool 52 may be set by means of a disc 54 engaging the slotted end of the tool holder. Bearing-bushes for the driving-shaft are provided at 25, 26 and lubrication may be effected through a hole 27 above a reservoir 28 which communicates with passages to lubricate the driving-shaft and grinding-spindle. An angle-plate 31, Fig. 2, may be secured to an engine block to be rebored and is fitted with a bearing-block 34 which is normally secured to the angle-plate but may be moved vertically to permit inspection of the work. The grinding-bar is mounted in bearing-bushes in this block and is driven by a worm wheel 38 splined on the bar and driven from a shaft 47. The bar is fed thiough a feed block 43 by a lead screw 42, the latter being diiven by worm gearing 46 which may be coupled to the shaft 47. The direction of the vertical feed may be changed automatically and the radial feed of the grinding wheel may also be effected automatically by stops on the bar 41 coacting with the star wheel 19, the vertical length of the stop determining the amount of feed. The grinding-bar may be supported at both ends as shown in Fig. 5 a pair of eccentric bushes being provided as shown for supporting the grinding-spindle which is driven as above described from a shaft 24. In the case of large cylinders, the grinding-bar may be of skeleton formation and in some cases the cylinder may be moved longitudinally over the grinding-bar. In another modification, the boring-bar may be composed of two sections and the ends of the driving-spindle may be connected together by interengaging semicylindrical portions. The apparatus may be used for taper boring by feeding the tool during its passage through the work.

Title: Improvements in and relating to lift truck
IPC: B62B3/065
Filed: 1941-10-02
Abstract: 554,532. Lifting trucks. TRIGGS, W. W. (Yale & Towne Manufacturing Co.). Oct. 2, 1941, No. 12758. [Class 108 (i)] The ram and pump (having a cylinder 62) of the hydraulic lifting mechanism form part of an assembly pivoted at its lower end by a shaft 43 to a wheeled lifting-head 10 steered by a handle 16 which can be swung vertically to actuate by means of a ball-ended strut 17 a pumpdriving lever 15 pivoted on standards 37 of the lifting-head 10 and engaging the piston-rod of the pump by a roller 41. The ram lifts by a thrust-pin 13 a standard 12 (shown in the raised position chain-and-dot line) fast with the platform 11, links 44 pivoted at 46 on the platform 11 and connected at 43 and 48 respectively to the lifting head 10 and rods 51 serving to lift the rear end of the platform by means of forks 54 and links 55, borne on the rear wheels 19 and pivoted at 11a to the platform, the lifting being accompanied by extension of the truck wheel-base. Fig. 15 shows a modification of the hydraulic system, in which the pump 62 is actuated by pedal-operated rods 132 and the ram 137 has within it, for obtaining a quick-lift under light load, a stationary sleeve 140 through which liquid passes into a space 142 below a cap 143 of the ram 137. In Fig. 6 are shown control valves for the hydraulic system, a treadle-operated axially-rotatable rod 106 being formed with a camsurface 107 for opening a valve 91 to connect the pump cylinder to the fluid reservoir so that the movements of the pump piston will not produce a pressure in the ram and the handle 16 will be movable without actuation of the pump. A further movement of the rod 106 will advance the valve 91 to move the valve 96 off its seat to connect the ram to the reservoir and so effect the lowering of the load. The valve plug 94 of valve 96 is shaped so as to prevent appreciable flow of fluid past the valve seat until a relatively large opening has been produced by outward movement of the valve from its seat. The adjustment of the control valves into three different positions by the treadle is such that a second position may be passed over by allowing quick movement from the third position (in which there is a free passage between the ram and reservoir.). Specification 554,557 is referred to.
Patent GB-474768-A (GB)
Title: Improvements in or relating to electric protective arrangements
IPC: H02H3/40
Filed: 1936-05-06
Abstract: 474,768. Protective cut-out systems. REYROLLE & CO., Ltd., A., and LEYBURN, H. May 6, 1936, No. 12815. [Class 38 (v)] In a distance-protective arrangement, in order to compensate for currents flowing, as the result of a fault, in phases other than that on which the measurement is being obtained, a current proportional to that flowing in the other phases is injected into the measuring apparatus in the faulty phase in which the measurement is being obtained. In Fig. 1 (not shown) it illustrated a multiple-earthed system, comprising a generator with earthed neutral feeding a transformer with earthed neutral, in which a fault current i divides at the earth-fault into i1 flowing back through the generator-neutral, and i2 returning via the transformer neutral and thence dividing equally between the healthy phases. It is shown that, if Z1 is the phase-impedance to earth and Z2 is the interphase impedance, the voltage-drop is i1Z1+ i2Z2 or iZ1 - i2(Z1 - Z2) which is proportional to the earth-fault impedance as would be measured by the voltage coil of a distance relay, whereas the uncompensated voltagedrop, such as on a dead-ended feeder or feeder in a network earthed at one point only, is iZ1, which gives the true impedance value. Fig. 2 (not shown) illustrates conditions obtaining with a double-earth fault on a system which is insulated or earthed only through an arcextinguishing coil. In the multiple-earthed system shown in Fig. 3, the star-connected current transformers E<1> ... E<3> energize the current coils F<1> ... F<3> of the distance-relays, which coils are shunted by the secondaries G<1> ... G<3>, respectively, of compensating transformers H, J, K, each of which has two primaries energized by the currents in the other two phases that is, in the case of H, primaries H<2> , H<3> energized by B<2>, B<3>, respectively. The two primaries of each transformer H &c. have the same number of turns and are so wound that their effects are additive on the secondary, which is connected to the relay coil in a sense to oppose the current-flow therein when fault current is flowing in the healthy phases in the opposite direction to that in the faulty phase. The turns-ratio is (Z1 - Z2) / Z1, so that the resultant current acting on the relay is (i1Z1 + i2Z2) / Z1 and, as the voltage-drop is (i1Z1 + i2Z2), the relay will operate with the true impedance-value Z, instead of with the value (i1Z1 + i2Z2) / (i1 + i2), and would therefore be set to operate at the natural value, i.e. that for an open-ended line.

Filed: 1928-05-03
Abstract: 289,858. Luxor-Film Ges. May 4, 1927, [Convention date]. Bichgromated colloid processes.-Finely-detailed prints are produced on bichromated colloid layers with a short time of exposure (for example 1/5 to “ second) by treating the layer after printing, and before the usual development with cold water, with a moist atmosphere of water vapour at a temperature not exceeding 40‹ C. The vapour may contain weak volatile acids, such as acetic or carbonic acid. After development in cold water, the prints may be coloured in the usual way; or they may first be subjected to an uniform additional exposure, which may commence at any time during or after the vapour treatment. A further additional exposure may be given through the support of the layer either before or during the vapour treatment; but the. intensity and duration of this exposure should be such that its effect is limited to the deeper-situated portions of the layer. Layers are described which are sensitized by a concentrated solution of bichromate (3 to 10 per cent) followed by a short treatment, while still wet, with pure water or with a weak solution of bichromate (up to 2 per cent).
