Title: An improved lifting and dumping or ring discharge grab
IPC: B66C3/06
Filed: 1922-03-07
Abstract: 200,543. Cooper, H. M., and Willmott, H. B. March 7, 1922. Grab-buckets.-Relates to grabs which are discharged by dumping or by engagement with a suspended ring, of the type in Which the buckets a are hinged to spreader arms b and to a lower frame d which is raised and lowered by a guided hook-carrying cross-head g. Flexible guides are provided for the cross-head g, comprising parallel ropes or chains h, Figs. 5 and 7, passing through guideways j in the cross-head. The ropes h are fixed at one end to the grab-head c, and in order to keep them taut during the opening and closing of the buckets, each rope is reeved around sheaves k, m on the lower frame d, and a sheave n on the bucket or spreader arm, and are secured to the lower frame. The spreader arms b at opposite sides of the grab are connected by links o' to an equalizing lever o pivoted on the grab-head. Cushioning. The opening movement of the buckets may be cushioned by a dash-pot, or by passing the lifting-rope i<1> over a sheave p on the grab-head and securing the end to the rim of a sheave p', Fig. 8, turning with the bucket on the outer bucket-hinge, so that when the buckets are opened the rope i<1> is wound on the sheave p<1> and the whole of the grab is raised. Releasing by dumping. The hook f, Fig. 4, on the cross-head g is constructed as described in Specification 175,325, and tends to turn to the position shown in broken lines when the shoulder f<3> is released by movement of the lever s. A weighted lever r, Figs. 4 and 7, pivoted on the cross-head rests on the lever s and disengages it from the shoulder f<3> when the grab is lowered to the ground and the weight of the buckets is no longer supported by the hook f. When the crosshead has been lifted to discharge the grab and is again lowered, the lever r rests on a bar t on one bucket so that when the hook f is engaged by the bucket hinge and returned to the normal position, the lever s engages the shoulder f<3> in readiness for closing the buckets. Releasing by engagement with suspended ring- A lever u, Fig. 7, pivoted on the grab-head passes up freely through the discharging ring, and on again lowering the grab, the lever is engaged by the ring so as to turn a lever v and raise a rod w, which at its lower end engages and raises a lever x, Fig. 4, thereby lifting the lever s and releasing the hook f.

Title: Improvements in or relating to electrostatic machines
IPC: H02N1/10
Filed: 1955-03-08
Abstract: 766,056. Electrostatic generators. SOC. ANON. DE MACHINES ELECTROSTATIQUES. March 8, 1955 [March 8, 1954], No. 6793/55. Class 35. In an electrostatic generator of similar construction to that described in Specification 719,687, having a rotating charge-carrier 1, opposite charges are arranged on the inside and outside faces of the carrier and chargeinducing plates and ionizers are arranged in groups a, b of opposite polarity which are mutually self-exciting. On either side of the carrier there are input ionizers 4, 5 connected together, output ionizers 8, 9 connected to their respective inducers 10, 11 on the opposite side of the carrier, and input inducers 6, 7 opposite the respective input ionizers but connected to the output ionizer on the same side of the carrier. In this way mutual excitation is effected between the two faces of the carrier. The input ionizers are connected to a terminal 17 which may be earthed to produce outputs of +u and - u at terminals 15, 16. Alternatively, by insulating this terminal and earthing one of the others, + 2u or - 2u may be obtained. The inducer plates 6, 10 and 7, 11 of opposite polarity in each section may be joined by a semi-conducting layer 12, which may envelope the inducers, for grading the potential. According to modifications, various numbers of elecstatic sections may be arranged on either side of the carrier and connected in various ways. However, in each case the input ionizers and inducers and the output ionizers on any particular side of the carrier must have the same polarity; the output inducers on the same side have the same polarity; and each input inductor on one side is connected to an output inducer on the other. Thus a machine is described having six parallel connected units in each section, the units having the same polarity being joined side-by-side. Alternatively the units may be arranged such that those of alternate polarity are arranged in sequence round the machine. In a further modification a single unit acting on one side of the carrier excites two parallel connected units acting on the other side, these units exciting the first. Alternatively the two like units may act independently to produce three output voltages. A further modification having two mutually exciting sections as in Fig. 1, except that the negative section is only used to excite the positive section, and so has axially shorter electrodes 4, 6, 5, 7 using only part of the full length of the carrier. The machines may be of disc form. Specification 719,687 is referred to.

Title: Improvements in the manufacture of silica glasses
IPC: C03C23/00
Filed: 1956-03-05
Abstract: 783,244. Glass manufacture. QUARTZ & SILICE. March 5, 1956 [March 5, 1955], No. 6830/56. Drawings to Specification. Class 56. In the manufacture of silica glass, the very pure glass, in substantially its final shape, is subjected to the action of a continuous electrical field at high temperature. In this way, the silica glass loses all fluorescence and an absorption band of ultra violet rays in the region of 2450 AU is removed. In order to remove an absorption band of infra red rays in the region of 2À75 u, the silica glass is obtained from primary materials not containing any OH ions and the melting is carried out by any suitable means other than flames. Preferably the primary materials are reduced to very fine particles, e.g. powders formed by the oxidation of organic compounds of silicon. The shaped article is then placed between metallic electrodes and the assembly placed in a furnace and raised to a temperature of about 1000C. for about 30 hours, while a continuous field of 1000 volt/cms. is applied between the electrodes for the same period, producing a very thin layer of quartz or cristobalite which is then removed.

Title: Improvements in Apparatus for Indicating the Depth of Liquid in a Vessel.
Inventor: MURPHY LEONARD
IPC: G01F23/16
Filed: 1918-04-29
Abstract: 116,878. Murphy, L. April 29, 1918. Indicators actuated by pressure of head of liquid. -Relates to apparatus of the kind described in Specification 23411/06, [Class 106, Registering &c.], in which air or other gas is forced into a gauge reservoir until the pressure on the indicating liquid is that due to the depth of liquid in the vessel to be gauged, the gas being introduced through a tube dipping into the indicating liquid which automatically seals the indicator against leakage of gas, excess gas escaping through the line tube dipping into vessel. In the apparatus described in the abovementioned Specification, if the cock in a line tube is inadvertently closed, the air pressure might force the indicating liquid out of the gauge tube, or the spring-pressure gauge might be strained. To avoid the danger, a vertical tube E open at the upper end is connected to the seal chamber D, and the cross-sections of the tube and chamber are so proportioned that when the gas pressure reaches a certain value, the lower end of the tube C, which conveys the gas pressure from the compressor A, becomes uncovered, thus preventing further rise of pressure, the compressd gas flowing back into the compressor on each return stroke. The level is indicated by a pressure gauge M, by a liquid indicator L, or by an indicator actuated by a float in the tube E.
