Abstract: 359,433. Tractor-trailer couplings. MASTERS, E. A., Hove To, South Wonston, Sutton Scotney, Hampshire. July 17, 1930, No. 21708. [Class 79 (iii).] In a vehicle coupling device of the kind in which a trailer draw-bar is pivotally connected to a U- shaped frame which is horizontally pivoted to the rear axle casing of the tractor vehicle, the closed end of the U-shaped frame is substantially semicircular and serves as a rail upon which rides a carriage, the draw-bar and the rail passing through the carriage in directions mutually at right-angles. The U-shaped frame comprises a continuous metal strip 12 shaped to pass under the end of the vehicle, with stiffening strips 13, a coupling pin cross-bar 15 and a transverse stay 14 or a pair of diagonal stays. Springs may be provided to take the weight of the frame. The draw-bar 17 passes through a carriage, Fig. 3, riding on the semicircular end of the frame, and is connected by a pivot pin 16 to the centre of the cross-bar 15, a slot 25 allowing relative endwise movement for automatic application of brakes. The cross-bar 15 may be a laminated spring or springs may be provided on the pivot pin to render the connection resilient in a vertical direction. The carriage comprises a pair of angle-ended plates 18 each bent to U-form to embrace the rail 11 and riding thereon by means of rollers on transverse connecting pins 19, 21. The draw-bar passes between the vertical arms 18 and between rollers on horizontal connecting pins 22, 24, the lower one of these being furnished with a winged nut 23 to facilitate disconnection. The free ends of the frame parts 12, 13 are spaced apart to engage lugs 28 on the axle casing being detachably connected thereto by pins 27. The lugs 28 may be welded or otherwise permanently secured to the axle casing but are preferably detachably connected thereto by chains as shown in Fig. 5, the lug being in the form of a plate with a re-entrant serrated edge 30 and having a halved-joint connection to a transverse plate 31 formed with a serrated edge 32 and a series of slots 33 in its curved back to allow alternative assemblages to fit differently shaped casings. The chain 34, pinned at one end to the plate, is passed round the axle and secured at the other end by a shackle 35 engaging a notch 37 in the plate, the connection being tightened by a screw 36. The Provisional Specification describes an arrangement wherein the chain is tightened by one or more bolts passing through the chain intermediately of its length and bearing upon the axle casing.

Title: Improvements in or relating to automatic or semi-automatic telephone systems
IPC: H04M15/10
Filed: 1939-07-26
Abstract: 531,581. Automatic exchange systems. MERCER, R., (Associated Telephone & Telegraph Co.). July 26, 1939, No. 21780. [Class 40 (iv)] Charging rates are automatically determined by a switch which, in response to a digit or digits of the zone and exchange of the wanted party, selects a wiper of a second switch which is set by further digits, the arrangement being such that for some exchanges the same wiper is selectable over a number of contacts of the first switch. This meets the case of exchanges having the same rate and the same exchange digits appearing in different zones. As shown, a bi-directional switch TD1 in response to two digits selects a wiper of switch TD2 which is set by two further digits to select a lead 1-5 in accordance with the charging rate. In cases where the first and second digits identify the zone and the third and fourth digits the exchange and identical exchange digits occur in two zones, the same wiper of TD2 may be selected in response to different zone digits provided that all the exchanges with identical designations in the two zones have the same charging rates. In cases where an exchange has a capacity exceeding the normal 1000 lines, uniformity of numbering is preserved by using a single zone digit so that more than one wiper of TD2 may be employed for such a zone, and, further, all the contacts in the selected level of TD2 are connected in multiple since the fourth digit is not an exchange digit unless the fourth digit discriminates between a parent and satellite exchange having different charging rates. Increased capacity may be obtained by using a second switch similar to TD2 and operated synchronously therewith. The switches may also determine the routing number by using a further wiper of TD1 and other wipers of TD2. Specifications 516,348 and 523,443 are referred to.

Title: Method of generating oscillations in bodies of any desired form, for example conveyors of circular-ring, spiral or helical type, and apparatus for carrying the method into effect
Inventor: MAHLFELDT WALTER
IPC: B06B1/16
Filed: 1956-07-18
Abstract: 838,072. Vibratory mechanisms. UHDE G.m.b.H., F. July 18, 1956, No. 22186/56. Class 80 (4). A body such as a helical conveyer 5 is oscillated about its vertical centroidal axis by two or more separately driven unbalanced mass rotary vibrators 7, 8, 9, which all rotate in the same direction and at the same speed and whose axes are all inclined at the same angle to the horizontal. Each vibrator comprises a single unbalanced shaft which may be combined with a mechanical or electrical drive, and is arranged either outside (as shown) or inside the body being oscillated. There is no mechanical or other coupling between the various shafts but they have such relative phase displacements, as shown in the three examples in Fig. 3, that they combined to eliminate any radial components and produce a rotary oscillation which causes self-synchronization. In the helical conveyer shown the angle between each vibrator axis and the vertical should exceed the pitch angle of the helix. In a modification an additional motor-driven unbalanced shaft is arranged vertically at the centre of the conveyer to superimpose a horizontal " rolling " movement on to the conveying movement. The phase and inclination of said additional shaft may be adjustable. The helical conveyer 5 may be combined with a conveyer spiral, or be replaced by a spirally-extending helical conveyer. The conveyer may be tubular or may comprise a trough of semi-circular, elliptical or angular cross-section constructed as a circular, helical or spiral conveyer. Separately driven helical conveyers may be arranged one above the other.

Title: Fluid pressure valves
IPC: F15B21/02
Filed: 1976-05-28
Abstract: The housing (12) of the valve (11) has openings (21 to 23) for connection to a pressure source and to a working element and to the pressure-medium discharge. The openings (21 to 23) can be connected to one another selectively by moving internal valve parts (46). In the rest position, the internal valve parts (46) connect the working opening (21) to the pressure opening (23). They can be replaced by a second set of internal valve parts which, in the rest position connect the working opening to the discharge opening. In both cases, the internal valve parts (46) are designed and arranged relative to the openings (21 to 23) in the valve housing (12) in such a way that, when the valve switches over, the closure of the connection of the pressure opening or discharge opening and the working opening is complete before the opening of the connection between the discharge opening or pressure opening and the working opening begins. The use of a unitary valve housing for both valve functions reduces the cost of manufacture and stockholding. <IMAGE>

Two compounds which form an azeotropic mixture, e.g. uranium hexafluoride and hydrogen fluoride, are separated from a vapour mixture of the two compounds by cooling the vapour mixture in heat exchanger 1 so that one of the compounds (UF 6 ) separates out in the solid state, condensing the residual vapour in column 2 which contains perforated plates 9. and then submitting the condensate to distillation whereby the vapours of the azeotrope leave the head of the column while the other compound (HF) collects as liquid in, and is withdrawn from, the base of the column. In the case of a mixture of UF 6  and HF, heatexchanger 1 is maintained at -40‹C., and the vapour entering column 2 is solidified by the presence of liquid nitrogen in jacket 7 and sleeve 8. Valve 12 is then closed, the liquid nitrogen in jacket 7 and sleeve 8 is replaced by dry air, and the distillation is carried out at a pressure of about 10 atm. The overhead vapours are passed to condenser 3. Part of the condensate is refluxed to the head of column 2, and the remainder is re-vaporized and recycled to heat-exchanger 1.
