Title: Improvements in spring suspensions for vehicles
IPC: B60G3/26
Filed: 1935-06-18
Abstract: 443,757. Vehicle spring suspensions. LAKSHMANAN, C. D. S., 259, Iffley Road, Oxford. June 18, 1935, No. 17478. [Class 108 (ii)] In vehicles each front axle is carried by a separate axle which is mounted on a radius arm or frame one portion of the axle being under the control of a spring, the arrangement being such that as the spring straightens freedom is permitted to the axle to avoid twisting strains. The side chassis members are at the front connected by a rod 5 upon which are pivoted two arms 3 carrying at their free ends separate wheel axles 8 which are each also associated with a spring 7. In one form the end of the arm 3 is slotted as at 4 while in another form the axle 8 is carried by a slotted member 9 secured to the spring so that when the spring straightens or alters its shape the axle is not subjected to strains due to different paths of the centre of the spring and of the end of the arm 3. The spring 7 is hinged at its forward end but connected by a shackle 2 at its rear end. Covers for the arms 3 may be provided and in the case of the member 9 spiral springs may be arranged at the ends of the slots. In a modification the rod 5 may be rigidly secured at its centre to the chassis and at its ends to the sliding blocks 6 so that each half of the rod 5 serves as a torsion spring, in which case the laminated springs may be dispensed with and the axles guided in slots formed in members carried by the chassis.

Title: Process for the production of organic iron and aluminium compounds
IPC: C07C31/28
Filed: 1951-07-25
Abstract: Organic iron and aluminium compounds of the type of metal alcoholates are made by reacting an acid-reacting solution of an anhydrous iron or aluminium halide in an anhydrous alcohol with ammonia or an amine in such a quantity that the solution becomes neutral or almost neutral, so that no precipitation of an iron or aluminium compound takes place.  The products are soluble in organic solvents, yield the corresponding hydroxide in water and are probably alcoholates. Preferably at least 3 mols. of alcohol are used per mol. of halide and dry gaseous ammonia or ammonia dissolved in an organic solvent is added until the solution is no longer acid to a wet indicator paper, which changes colour at approximately pH7, e.g. litmus paper or a paper impregnated with the sodium salt of 2,4-dinitrobenzene-azo-11-naphthol-31, 61-disulphonic acid.  Inert solvents, e.g. benzene or ether may be present to aid in the separation of the ammonium halide simultaneously formed.  Aliphatic, hydroaromatic or aromatic amines may be used but ammonia is preferred.  Chlorides are preferred halides.  Cooling may be necessary, e.g. with iron chloride the temperature should not exceed 50 DEG  C.  After removal of ammonium halide the product may be recovered by vacuum distillation of the solvent at below 50 DEG  C. In examples: (1) anhydrous aluminium chloride is dissolved in absolute ethanol and benzene and dry ammonia passed therethrough at below 60 DEG  C.; the chloride may be replaced by the corresponding bromide and ethanol by n-butanol; (2) sublimed ferric chloride is dissolved in n-butanol and benzene and ammonia passed at 40-50 DEG C. and in (3) (2) is repeated using dry cyclohexylamine in benzene instead of ammonia.ALSO:Organic iron and aluminium compounds of the type of metal alcoholates which are stated to be used as catalysts are made by reacting an acid-reacting solution of an anhydrous iron or aluminium halide in an anhydrous alcohol with ammonia or an amine in such quantity that the solution becomes neutral or almost neutral, so that no precipitation of an iron or aluminium compound takes place.  The products are preferably alcoholates.  Aliphatic, hydroaromatic or aromatic amines may be used but ammonia is preferred.  Chlorides are prepared halides.  Inert solvents, e.g. benzene and ether, may be present.  The process is described in Group IV(b) and in Examples compounds are made from (1) aluminium chloride or bromide, ethanol or n-butanol and ammonia (2) ferric chloride, u-butanol and ammonia and in (3) the ammonia of (2) is replaced by cyclohexylamine.

Title: Axially resilient pipe joint
IPC: F16L51/02
Filed: 1958-06-03
Abstract: 896,253. Expansion joints. FOSTER WHEELER Ltd. June 3, 1958 [June 3, 1957], No. 17764/58. Class 99(1). A pipe expansion joint having an imperforate corrugated wall structure is composed of an array of sheet metal trapezia 16, 17, 23, 24, Fig. 1, 4 and 5, which are disposed in an even number of axial rows 11, 12, 13, 14 with pairs of longer parallel edges and pairs of shorter parallel edges joined together as at 18, 19, 25, 26 over their whole length alternately in concertina fashion. The length of the short and long parallel sides of the trapezia in any one row is the same. Each row is connected to its neighbouring rows with the sloping edges of the trapezia in one row joined over their whole length to sloping edges in the neighbouring rows by corner members 30 formed of triangular segments 31, 32, Fig. 6, inclined at an acute angle and joined to each other. Towards their ends each of the joined longer edges of the trapezia of one row enters the space between two of the pairs of joined edges of the triangular segments, as seen in Fig. 4, so that the joined edges of the trapezia and triangular segments are interleaved but spaced axially from each other. Each corner member 30 is made from a sheet metal rhombus, Fig. 6, bent along its diagonal, the edges of the triangular portions being welded to the sloping edges of the trapezia. The rows of trapezia are each enclosed within a protective cover assembly 35, Fig. 5, each of which comprises two L-section members 36, 37 and a flat plate 38. The members 36, 37 are capable of relative vertical movement while lateral movement is prevented between the flange 43 and the plate 38, and between the legs 40, 42. Each of the corner members 30 is also covered by L-shaped members 57, 58, Fig. 8, which are secured to the members 36, 37 and are therefore capable of relative vertical movement. In another embodiment, Fig. 14, the trapezia are replaced by triangular members similar to the corner members 30 to form a regular octagonal structure.

Title: Improvements in or relating to paper making
Inventor: ASHOVER ERIC DOUGLAS
IPC: D21F1/00
Filed: 1965-04-28
Abstract: The wire mark formed on the underside of a paper web during its formation on a wire conveyor is removed or subsantially removed, by flowing water-for example white water-upwardly through the conveyor at a point downstream of the "dry line" but at a point not substantially dried than at the dry line so as to raise the web from the surface of the conveyor, and subsequently removing the added water by the application of graduated suction pressures.  The water is fed upwardly to the conveyor through a container preferably integrally joined to a number of suction boxes but separated from the first suction box by an overflow container.  An apertured cover of a frictionless material-e.g. a synthetic resin bonded fabric-covers the top of the suction boxes and water container.  Frictionless plates are situated beneath the cover so that the lateral extent of the suction boxes may be adjusted.  The container may be spaced from the dry line by one or more suction boxes.  Additives-for example coating compositions-may be incorporated in the water in the container.

Title: Charging pulse transmission system for time division telecom munications systems
IPC: H04M15/00
Filed: 1974-04-24
Abstract: 1459329 Automatic exchange systems SOC ITALIANA TELECOMMUNICAZIONI SIEMENS SpA 24 April 1974 [24 April 1973] 17895/74 Heading H4K In a metering arrangement for a TDM system a binary signal is inserted in one of two cyclic stores in dependence on whether the calling or called subscriber is to be supplied with a metering pulse, and the continued presence of the binary signal at the store output over a number of frames is used to cause a metering pulse to be supplied to the respective party. The arrangement comprises six cyclic stores which are rotated in synchronism and which each comprise a storage location for each time slot. To supply a metering pulse, a central control CD supplies the address Ut of the party to be metered via interface I 1  to a comparator C1, C2 where it is compared with the calling and called subscriber addresses circulating respectively in stores I and N. If a match is found with a calling subscriber address of store I a signal U 1  is sent to logic RP to cause a "11" signal to be stored in the corresponding time position of store LP. The appearance of this signal at the output of store LP causes a binary 1 signal to be inserted into store LT 1  and also causes a multiple counter comprising store LK and logic RK to start to count clock pulses CK by incrementing a storage location of store LK corresponding to that of the time position of the call. The binary signal in store LT 1  therefore appears at the output of this store once per frame until the counting location of store LK reaches a predetermined count whereupon the corresponding storage location of store LP is set back from the "11" state to its original state, thereby cancelling the binary signal circulating in store LT 1 . Had the address supplied by central control CD corresponded to a called subscriber address, the corresponding location of store LP would have been put in a "12" state and a binary 1 signal inserted in store LT 2 . The operation is then as given above. The pulses at the output of store LT 1  or LT 2  are gated to the line circuits (Fig. 3) of the corresponding circuit subscriber via diode matrix Mt which is addressed by the stores I and N. The pulses appear at T (Fig. 3) to cause transistor TR1 to charge a capacitor C, having a time constant greater than the frame period, thereby to turn on transistors TR2 and TR3 to cause a 16 Hz metering signal from supply O to be gated via a differential amplifier and transformers TA and TU to the subscribers meter U.

Title: Improvements in or relating to suction-hose filters cleaned by scavenging air
Filed: 1946-06-14
Abstract: 642,646. Air filters. BUHLER BROS. June 14, 1946, No. 17957. Convention date, June 15, 1945. [Class 8(ii)]. A multi-compartment suction hose filter of the kind wherein the compartments are periodically cleaned in interrupted sequence by reverse-flow scavenging air comprises auxiliary means which irrespective of whether a compartment is being scavenged serves to maintain constant the flow of air across a dust generating machine to which clean air is delivered by an exhaust of air in conduit connection with the filter and which machine exhausts dust-laden air to the filter. During normal operation dust-laden air from the machine enters a common inlet 23 and traverses, say, four out of five compartments each of which has an inlet flap valve 24 and an outlet flap valve 15 to give access to a common outlet 21. A single flap valve 19 in the outlet 21 is closed during a scavenging period when scavenging air is drawn through a valve 17 to pass through a through the. filter bags, and through a space 27a at the " closed position of the valve 24 to join, dust-laden air passing to the remaining compartments. During, intervals between scavenging the valve 19 remains open and air thus drawn into the outlet 21 compensates for the scavenging air drawn through a valve 17 into the filter during a cleaning period. The valves 15, 17 of each compartment are actuated by rods 14, 16 reciprocated by engagement of a cam roller 10 with a lug 12 of a lever 13 mounted on a fixed pivot 11a, and the single valve 19 is operated by a link 18. The bags of each compartment are shaken by a cam 9 rocking a lever 7 carrying a spring-biassed rod 4 from which is suspended a bag carrying rod 3. The valve 19 may be replaced by a throttle valve in the outlet 21 or in the inlet 23.
