Title: Improvements in wheel mountings
IPC: B62D55/108
Filed: 1945-05-16
Abstract: 634,983. Road-vehicle spring-suspensions. BASSICK CO. May 16, 1945, No. 12322. Convention date, March 22, 1944. [Class 108 (ii)] [Also in Group XXXI] In a wheel mounting including cushioning means permitting limited movement of the wheel under sudden impact, spring means primarily functioning to carry the vehicle load, and a wheel support movably connected to the vehicle body for upward movement of the wheel under load, the cushioning means and spring means are arranged for functioning substantially independently of each other, the cushioning means being disposed on the wheel axle and substantially concentrically thereto and between the wheel and wheel support, the spring means being disposed between the wheel support and the vehicle body. In .the construction described, each wheel 16, 17 is carried by tapered roller bearings 52, Figs. 6, 7, on a boss 44 eccentrically mounted on an axle 22 rigidly secured by nuts 42 to the ends of arms 19 which are pivotally mounted at 21 to the vehicle frame and comprise the wheel support. An inverted V-shaped arm 31, 31a, Fig. 1, centrally pivoted to a member 30, is capable of guided vertical movement relative to a housing 23 rigid with the vehicle frame, under the action of the spring means 32, 33. The outer ends of arms 31, 31a bear on pressure plates 36 on the arms 19 urging the latter downwardly. Load is transmitted to each wheel 16, 17 through the cushioning means in the form of a spiral spring 47 which is connected between the boss 44 and the arm 19. A collar 61 on an overhanging axial extension of the boss 44 carries a lug 60 which co-operates with a projection 62 on a bolt 49 securing the end of the spring 47 to the arm 19 to limit the rotation of the boss 44 under action of the spring 47. The roller bearings are secured by a nut 55 and thrust collars 57, 58, and oil sealing rings are provided. Under levelsurface conditions the wheel centre 64, Fig. 7, lies below and trails approximately 25 degrees (determined by the stop 60, 62) behind the axle centre 63 so that surface irregularities cause the wheel centre to move rearwardly and upwardly, the maximum angular movement (155 degrees) being limited by frictional engagement between adjacent coils of the spring 47. The wheel tyre 38 is of rubber engaging track links 10a secured by rods 39, projections 39a of which are engaged by a track driving sprocket.

A shaped article (such as a filament or film) comprising a mixture of a cellulosic material and cellulose crystallite aggregates may be made by mixing a film-or filament-forming cellulose ester or ether and the cellulose crystallite aggregates or derivatives thereof and extruding or casting the solution to form a filament or film. Alternatively a mixture of viscose and the cellulose crystallite aggregates or derivatives thereof may be extruded or cast to form a filament or film. The term " cellulose crystallite aggregates " (also referred to as level-off D.P. cellulose) is defined as the crystalline acid-insoluble residue remaining after the acid hydrolysis of cellulose. It is washed free from acid and recovered. The preparation of preferred aggregates for use in the present invention is described in Specifications 874,945 and 970,111. These aggregates have a particle size ranging from below 1 to about 250 to 300 microns. Instead of cellulose crystallite aggregates there may be used derivatives of these aggregates such as aldehyde derivatives, carboxyl derivatives, mixed aldehyde-carboxyl derivaties, ether derivatives and ester derivatives. Filaments and films according to the invention may be produced by continuously injecting an aqueous slurry of the cellulose crystallite aggregates into a viscose just prior to extrusion and then extruding the viscose into a coagulating bath in the usual manner.

Abstract: 252,380. Bonnebeau, R., and Bonnebeau, G. May 19, 1925, [Convention date]. Fluid - pressure. - In vacuum brakes operated for instance by the suction of the driving engine of the vehicle &c. and in which the co-operating members of the control valve are carried by the piston and ,connected to the brake pedal respectively so that a graduated action of the. brake is obtained corresponding to the extent of movement of the pedal, the control valve comprises a slide valve and a lift valve controlling the suction passage and the air inlet respectively. The slide valve member 17 is connected to the pedal by a rod 18 disposed in a tubular rod 6 extending from the piston 5, and is normally held by a spring 20 in the position shown in which it closes a passage 14 in the piston and holds open a lift valve 21 whereby the space 1<a> of the cylinder 1 is open to atmosphere by passage 15 and orifices 11 in the end plate 9 of the piston, which is connected by the rod 12 to the brakes. The passage 14 is connected by the cavity 13 in the piston and the orifice 4 to the suction pipe of the engine. To apply the brake, the rod 18 is moved upwardly by the pedal whereby the valve 21 closes and the passage 14 is uncovered so that a partial vacuum is established in the cylinder space 1<a>. The consequent movement of the piston recloses the passage 14. Further movement of the pedal is followed by further movement, of the, brake and thus the application of the brake can be graduated. Similarly the brake can be progressively released, the release movement of the pedal causing the. valve 21 to be opened and the consequent return movement of the piston effecting its closure. The piston can be directly operated, in the event of failure of the vacuum, by the engagement of a. shoulder 19 on the rod 18 with the plug 7 on the rod 6.

Title: Electrolytic methods for utilising iron chloride liquors
IPC: C25C1/06
Filed: 1943-08-09
Abstract: 572,866. Electrolytic extraction of iron and chlorine. BRITISH TITAN PRODUCTS CO., Ltd. Aug. 9, 1943, No. 12858. Convention date, Aug. 8, 1942. [Class 41] In an electrolytic process for the recovery of iron and chlorine from iron chloride liquors, derived for example from pickling processes in steel manufacture, or the "chloride" process for manufacturing titanium dioxide from ilmenite, the ferrous chloride constitutes substantially the catholyte and a calcium chloride solution the anolyte, to deposit at the cathode as electrolytic iron a major portion of the dissolved iron while liberating chlorine at the anode. Unelectrolysed iron is precipitated as iron hydrates, and the iron-free calcium chloride electrolysis effluent containing an amount of calcium chloride equal to that contained in the original electrolysis is concentrated and then returned to a subsequent electrolysis for use as anolyte. As applied to the "chloride" process, titaniferous ores are acted upon with hydrochloric acid to produce the iron chloride liquors. Calcium chloride introduced with the acid may be removed by introducing ferrous sulphate or sulphuric acid into the liquor. The residue comprising ferrous and ferric chlorides, a little hydrochloric acid and calcium sulphate, and impurities, has the acid neutralized by adding hydrate of iron from the electrolysis, and hydrate of lime. The ferric chloride is reduced to ferrous chloride by adding a small excess of scrap iron, and barium sulphide is added to eliminate the calcium sulphate and impurities from the ore. The residue, mainly of ferrous chloride, is electrolysed in a bath to which about 1 per cent. free hydrochloric acid has been added, the cell comprising a carbon anode, an iron cathode and a permeable diaphragm forming anode and cathode compartments. The iron chloride is introduced as catholyte and calcium chloride from a subsequent step in the process is introduced as anolyte. The chlorine evolved may be used in the treatment of the original titanium residue by the "chloride" process. When about 50-80 per cent. of the iron has been deposited, the effluent is treated with hydrate of lime to separate the iron as hydrate which is used in the preliminary step already described. The calcium chloride is then divided into two parts, one part being evaporated to concentrate the solution for reuse as anolyte, the balance being introduced into the "chloride" process and carried through with the hydrochloric acid, as already described. Alternatively the balance may be treated with ferrous sulphate or sulphuric acid to regenerate hydrochloric acid free from calcium chloride for use in extracting iron from the ore, in which case the initial treatment of the liquors with those compounds may be omitted.

Abstract: 1466765 Gaming machines BELL-FRUIT MFG CO Ltd 12 March 1975 [23 March 1974] 13034/74 Heading G4V A gaming machine has display means which operate during each game to select at random and display a combination of symbols wherein the display means comprises a screen on which the image of a combination of symbols is produced and made to change at random during each game by electronic scanning means which scans the screen repetitively. Fig. 1 shows picture information stored in "read only" memory units ROM1, ROM2 and ROM3. Each unit determines which particular symbol appears in a particular symbol position on screen S of a cathode-ray tube which is scanned in a series of horizontal lines by an electron beam. Control of scanning is by processing circuitry T. Information is read by read-out sequencer R from each memory unit in turn during each horizontal line scan on screen S so that an image of at least one symbol is built-up simultaneously in each symbol position as scanning proceeds through each frame. Such a build up is shown in Fig. 2 where the symbols displayed form a static image before being changed. Alternatively the picture information can be changed partially during successive scans so that the symbols appear to move from the bottom to the top of the screen. There could be two or three complete symbols displayed at each symbol position. A game control programmer P operates at random to stop the reading of further new information and the last scan is repeated indefinitely with the same picture information. Unit C compares this information with prize-winning combinations and operates prize awarding means W if a match is obtained. A colour cathode-ray display tube may be used. The picture information may be stored magnetically on tape which is single or multitracked. In the latter case two or more video signals are recorded on separate tracks which are read simultaneously and each produce symbol images in a corresponding symbol position on the screen. The signals may be all the same but phase shifted or delay units may be used. Alternatively, different signals may be recorded on each track so as to produce a different sequence of symbol images on the screen. Preferably, one of the tracks has win information recorded on it which is read simultaneously with the other tracks and is used to indicate whether or not the combination of symbols corresponding to the picture information then being read on the other tracks is a prize winning combination. Separate tapes may be used instead of a single multi-track tape.
