[Classes 79 (i), 79 (iii), and 79 (iv).] In a motor vehicle or tractor in which the power unit is located in a drum serving as the driving and steering wheel, the shaft 7 upon which the drum 1 is rotatably mounted supports the power unit 16 and is secured at its ends to the arms of a fork 5 pivoted at 5<1> to the vehicle frame 2, the fork 5 being also connected to the frame below the pivot 5<1> by movable coupling means which transmit the greater part of the tractive effort to the frame. In the construction shown the additional connection comprises a bar 10 curved about the pivot 5<1> as centre and having its ends 10<1> formed with eyes mounted on the shaft 7, the centre part of the bar bearing against rollers 11 on the frame. In a modification, instead of the bar 10 a flexible cable is used, this cable passing round pulleys on the frame and having its ends secured to the fork 5. A frame 15 rigid with the shaft 7 carries the engine 16, clutch 19, changespeed gear 20, radiator 17, and fuel and oil tanks 18. The drum 1 is driven from the final shaft 21 of the change-speed gear through a pinion 22 gearing with a toothed ring 23 on the drum. The hollow shaft 7 is divided into two parts by a partition 7<11>, and the exhaust gases pass from the engine through a pipe 24 and one shaft part to the atmosphere. Air is drawn in through the other shaft part by a fan 25 which forces it through the radiator 17, this air also cooling the various parts of the power unit and escaping through holes 27 in the drum. Part of this air goes to the carburetter through a hole 7a in the shaft. The clutch and change-speed gear are respectively controlled by rods 28, 30 passing through the shaft 7 and connected at their outer ends to operating levers (not shown) mounted on the fork 5. The ignition and throttle may be controlled by Bowden wire mechanism. The drum is steered by worm gear 8, 9.

Title: Improvements in filtering apparatus
IPC: B01D33/00
Filed: 1925-02-11
Abstract: 254,764. Bramwell, B. Feb. 11, 1925. Filters with loose filtering-materials. -Filters of the kind in which sand or other finely-divided medium is supported in such a manner that the whole of the material can be withdrawn at the lowest point of the chamber for cleansing, the cleansed material being subsequently returned to the filter system, are arranged so that the liquid under filtration flows in substantially vertical stream lines downwards through the effective part of the bed and the filtrate leaves the filter bed in an upward direction. The filter A, Fig. 1, is provided with a depending liner C which forms an annular chamber for the discharge of the filtrate. Water to be filtered is supplied by a pipe E and filtrate discharged by a pipe G. To cleanse the medium it is withdrawn at the bottom B by water under pressure from the pipe F and carried up a pipe H to a wash-chamber D, from which the wash-water and impurities are discharged through a pipe I and the cleansed medium returned to the top of the filter. Vertical baffles may be provided to secure downward stream line flow through the bed, and perforated plates or gauze may be arranged in the annular chamber to prevent particles of the medium passing away with the filtrate. In a modified form of filter the filtrate is withdrawn through a central vertical pipe open at the bottom as well as through an annular chamber. The upper part of the filter, Fig. 5, partitioned off by a perforated plate P, forms a sand and wash-water separating chamber, the wash water and impurities being discharged through a pipe I. A single wash chamber may be used in connection with a number of filters, or, where several filters are provided, fouled medium from one may be washed as it is passed to another. Fig. 12 shows an arrangement of two large filters, each divided into several sections from which the medium can be separately withdrawn to a wash-chamber S for cleansing.

Title: Stabilised polyester fibres
Inventor: DAVIES DUNCAN SHEPPEY
IPC: D06M13/152
Filed: 1954-02-12
Abstract: The stability and tensile strength of filaments or films of polyesters from terephthalic acid, a glycol of the formula HO(CH2)nOH, where n is 2-10 and a polyalkylene oxide of molecular weight above 1,000 is improved by treating the filaments or films with a solution or dispersion of a substance known to be an anti-oxidant for rubber.  The glycol used is preferably ethylene glycol and the polyalkylene oxide is preferably polyethylene oxide of molecular weight 1,000-6,000.  The anti-oxidant is preferably a p-phenylene diamine derivative, particularly N - N1 - di - b  - naphthyl - p - phenylene diamine.  Other anti-oxidants which may be used are mono- and poly-hydric phenols, di-hydroxydiphenyl methanes, quinones, diarylamine derivatives, diphenoquinones, phenothiazine derivatives and dihydroacridine derivatives.  The anti-oxidant may be applied in any solvent which is harmless to the polyester fibres, but an aqueous solution or dispersion is preferred.  In an example, fibres of the polyester made from 100 parts of terephthalic acid, 85 parts of ethylene glycol and 15 parts of polyethylene oxide, was treated at 100 DEG  C., with an aqueous dispersion of 0.2 per cent by weight of N-N1-dib -naphthyl-p-phenylene diamine, containing 0.2 per cent of sodium oleyl sulphate as dispersing agent.  A length of the fibre so treated and maintained at 213 DEG  C. withstood a specified tension for approximately ten times as long as an untreated fibre. In other similar examples employing as the treating agent (a) 2,21-dihydroxy-3-31-di-t-butyl-5-51-dimethyl, and (b) 5-phenyldihydroacridine when maintained at 213 DEG  C. withstood a specified tension for approximately four times as long as untreated fibre.

Title: Improvements in or relating to level-regulating hydropneumatic vehicle suspension units
IPC: B60G17/044
Filed: 1969-01-27
Abstract: 1,261,555. Self-levelling suspension units. HOESCH A.G. 27 Jan., 1969 [17 April, 1968], No. 4398/69. Heading F2S.  In a self-levelling hydropneumatic suspension unit, Fig. 1, there are two discrete gas-filled spaces 171, 191 pressurizing respective liquidfilled chambers 172, 192 and flow between these chambers is controlled by level-regulating means located inside the hollow rod 7 of a piston 10 acting in a cylinder 11 which communicates with the chambers 172 and 192. The level-regulating means consists of a pumping piston 25 having a hollow rod 24 and a tubular valve element 32 located inside the main piston rod 7 but outside the pumping piston and axially displaceable with respect to both of them. The valve element carries at one end a stop 36 engageable by the pumping piston and at the other end a closure element 33 for a valve seat in the piston. Thus excessive inward movement of the main piston opens a passage 45 through that piston and effects level regulation by transfer of fluid between chambers 192 and 172. The arrangement of valves, ports and passages shown in Fig. 1 is such as to achieve the customary pumping and level-regulating action in a vehicle in motion. However, there is also provided a seal 54 to prevent leakage past the piston 10 when all level-regulating control valves are closed. The effect of this is that the vehicle load can be increased when the vehicle is stationary and the unit will not contract. In addition to the levelregulating control valves, the piston is provided with valves 48, 49 for damping the piston's oscillation when the vehicle moves, such damping being independent of the load-induced levelregulating function. There is also provided a limit valve 51 in the lower end of the cylinder, this valve opening a passage to the chamber 172 if the pressure below the piston in the cylinder 11 falls below a predetermined value.  In Fig. 4, the gas and liquid chambers 191 and 192 of Fig. 1 are replaced by gas and liquid filled compartments in a separate reservoir 55 which screws on to the main housing 3 of the unit. The upper end of the housing 3 has a vehicleconnection pin 56 on to which the reservoir 55 is screwed. The pin and the reservoir have respective valves 57, 59 which open each other when the reservoir is screwed on and close if it is removed. The chambers 171 and 172 of Fig. 1 are replaced by chambers 611 and 612 whose inner peripheries are bounded by a tubular plastics insert 62 sealed into the housing 3 at the upper end only.  Fig. 5 (not shown) depicts an alternative construction, generally similar to Fig. 1 but lacking the damping valves 48, 49 and the limit valve 51. Also, the means for limiting the pump. ing range differs from that of Fig. 1: in Fig. 1 an axial groove 35 in the valve element 32 can bypass the pumping piston, pumping ceasing when (as in Fig. 1) the pumping piston is above the groove; in Fig. 5 the main cylinder has a corresponding groove for by-passing the main piston.
