IPC: F01K3/24
Filed: 1927-04-13
Abstract: 269,565. Siemens Schuckertwerke Ges. April 19, 1926, [Convention date]. Motor power plant ; regulating; working-fluid supply.-In steam power installations wherein the steam is generated in the neighbourhood of the critical temperature and pressure, and throttled in an auxiliary turbine 4 before admission to the main turbine 5, the steam is superheated with simultaneous reduction of pressure before admission to the throttling turbine 4. This is effected by passing the steam from the critical pressure generator 1 into a superheater 14 dimensioned to give the desired fall of pressure. A superheater 15 may be interposed between the turbines 4, 5, admission temperatures for the two turbines being the same. The exhaust from the turbine 5 is passed through a superheater 6 on its way to other consumers. The pressure in the superheater 14 and the admission pressure of the steam for the turbine 5 are maintained constant by pressure-actuated valves 9, 10. Valves 27, 26 controlling the supply of fuel and water for the generator 1 are actuated by a device 25 responsive to pressure changes resulting from load changes on the turbine 5.

Abstract: 705,073. Prestressed concrete. BAKKER, J. May 1, 1951 [Jan. 4, 1951 ; March 20, 1951], No. 10178/51. Class 20 (4). [Also in Groups XXI and XXV] A reinforcing e'ement for prestressed concrete comprises a flat band or a rod of square crosssection of steel and at least one sleeve-shaped member which is used for stretching and/or anchoring purposes, the band or rod being provided with shallow teeth on the narrower side faces or corners for co-operation with internal teeth of the sleeve-shaped member. The teeth may be formed as parts of a screw thread and the sleeve-shaped members may be nuts which are screwed onto the reinforcement. The nuts may have the thread cut away at at least two diametrically opposite points so that they can be slid along the reinforcements to any desired position and locked in the position by being turned so that the threads engage those of the reinforcement. In the case of a band shaped reinforcement threaded filling-pieces of approximately semi-cylindrical section may be placed on either side of the reinforcement where the nuts are to be positioned. The reinforcements may be tensioned by the device shown in Fig. 4 which comprises a plate 9 bearing against a side-wall 7 of a mould and having slots 8 through which a reinforcement 2 passes and a correspondingly slotted guide spindle 10 integral with the plate 9 and of a diameter slightly less than the width of the reinforcement being tensioned. A nut 12 is screwed onto the reinforcement and is tightened to tension the reinforcement, a ball-bearing 13 being mounted on the spindle 10 to allow the nut 12 to be turned easily. The band-shaped reinforcements may be used singly or a number may be used lying directly on one another or mutually spaced. A reinforcement comprising a number of bands may have sleeves to hold the bands together and some of the bands may be under compressive and some under tensile stress. The reinforcements may be used to reinforce concrete piles (see Group XXI) and may be arranged so that they can be withdrawn from the pile when it has been driven into a desired position.

Title: Improvements relating to connections between relatively oscillatory parts
IPC: F16F7/06
Filed: 1951-05-02
Abstract: 693,531. Spring suspensions; resilient points. DAIMLER-BENZ AKT.-GES. May 2, 1951 [Dec. 20, 1948], No. 10270/51. Classes 108 (ii) and 108 (iii). In a connection between two relatively oscillatory parts, relative oscillatory movement within a certain limit is taken up by an elastic sleeve arranged in the connection and coupled by frictional - engagement means with at least one of the parts, relative movement beyond the limit being permitted by slip in the frictional engagement means produced solely by a force transmitted through the elastic sleeve itself, which sleeve is provided with metal armouring, for example steel bushes, both on its inside and its outside. In the arrangement shown in Fig. 1, as applied to a parallel link suspension, in which a pair of links d and e are pivotally connected to a vehicle frame a, rubber sleeves m enclosed in metal sleeves are disposed concentrically of pivot pins hand k respectively. In a modification, Fig. 3, in which rubber sleeves m are enclosed in inner and outer sleeves m and o respectively the outer sleeves o engage tightly, bores in a link d and the inner sleeves n frictionally engage mounting pivots l, l<1> which are secured against rotation by screws are formed with right and left-hand threads respectively and are engaged by a turnbuckle nut r by which the amount of engagement of the pivots with the sleeves n is varied. In another arrangement, Figs. 4 and 5 (not shown), each mounting pivot is formed as a double cone, the pivot being rigidly secured by one conical part and the other conical part being frictionally engaged by an inner rigid sleeve of a conical rubber bush having an externally cylindrical outer rigid sleeve and located in a bore of a swinging link. The frictional engagement between the inner rigid sleeve and the pivot is produced by a spring, the compression of which is adjustable. In further modifications the inner or the outer or both rigid sleeves may be mounted for frictional engagement. The invention may be applied to all the pivotal joints of the parallel link suspension and the friction engagement be produced between friction discs subject to spring pressure. In a modification of the Fig. 3 arrangement the pivots l, l<1> may extend through the sleeves n and carry abutments for springs and friction discs. The rigid sleeves may be coated with copper, cadmium or the like.

A small quantity of oil sucked through the valve 26 into the chamber 21 keeps the supply therein approximately constant.
Patent GB-105546-A (GB)
IPC: F02M31/18
Abstract: 105,546. Dunan, P. L. April 13, 1916, [Convention date]. Spray carburettors; vaporizers, external.-In a carburettor for heavy-oil motors, in which the mixture is passed through a chamber heated by exhaust gases and in which a valve regulates the inflow of liquid fuel and of the secondary air, the heating-chamber K is divided into elements or passages 3, 4 each communicating by separate outlet passages M<1>, M<2> with the inlet uptake A for secondary air, the inlet passages L<2>, L<3>, L<4> to the heated chamber K being closed by valves N<2>, N<3>, N<4>, Fig. 4, the opening of which is effected by the lifting of the regulating-valve E; the valveless inlet passage L' to the heater K admits sufficient fuel for light and slow running, while the wider opening of the throttle will cause the valves N<2>, N<3>, N<4> to open in succession. The valves N<2>, N<3>, N<4> will open when their rods engage the lower ends of hollows e<2>, e<3>, e<4> of different length in a slotted rod E<1> carrying the needle valves F, F<1> and the control valve E, and the mixture, consisting of fuel from the valve F, additional liquid such as water from the valve F<1>, and primary air admitted through the orifices J, will pass through the respective elements of the heater K to the inlet uptake A. The rapid lifting of the valve E, and also therefore of the valves F, F<1>, due to a sudden reduction in pressure in the uptake A, is prevented by a damping-device comprising a valve T in the head of the valve E normally held down by a spring and closing a chamber U between the head of the valve E and a partition V integral with the fixed tube G, this chamber communicating with the atmosphere through a valve W normally held open by a spring. The springs of valves T, W are arranged to yield to predetermined differences of pressure. A sudden reduction of pressure in the uptake A causes the valve E to rise, and if the pressure within the uptake A is sufficiently reduced, the valve T will open, thus admitting air and preventing the excessive lifting of the valve E. The resulting reduction of pressure in the chamber U, while allowing the valve T to open again, will cause the valve W to be closed, and the rate at which the valve E can then rise will be determined by the rate at which air can pass into the chamber U through an aperture v, the section of which is calculated for a definite velocity of ascent of the valve E. When the valve E comes to rest, the valve W will open again and leave the valve E quite free to fall. The inner wall K<1> of the heating-chamber K is open at both ends and may be heated up by a suitable burner P for starting.

Abstract: 698,966. Plate heat-exchangers ; surface condensers ; film heat-exchangers for cooling liquid. CHLOBERAG CHLOR BETRIEB RHEINFELDEN AKT.-GES. May 4, 1951 [Dec. 23, 1948], No. 10563/51. Class 64 (iii) [Also in Group XII] In an arrangement in which liquids, gases or vapours having a corrosive or etching action, e.g. hydrogen chloride or chlorinated organic solvents, are cooled or condensed or such a gas is absorbed (see Group XII), hollow elements of graphite (or pressed thermosetting or thermoplastic synthetic material containing graphite) are assembled to form a column. Lenticular hollow elements 11 are interconnected by nipples 12, also of graphite &c., each axially bored but closed at one end adjacent lateral outlets 13 through which fluid flows from the bore radially into the next element. As shown in Fig. 1 liquid or gas to be cooled flows upwards through the column which is located in a vessel 14 containing cooling liquid such as water. A medium to be cooled, such as a liquid, may flow down outside the column through the vessel 14 and be cooled by a liquid, which may flow upwardly, inside the column. If the treated liquid is to flow in a thin layer over the column for cooling, e.g. while absorbing gas, it is collected and distributed by channels 35, Fig. 3a, any gas for absorption flowing up or down the inside of the vessel 14. The vessel 14 may be rubber lined or made of material to resist corrosive gases. For condensing a vapour flowing down inside the column, by means of a cooling liquid in the vessel 14, lenticular elements shaped as in Fig. 2a are used so that condensate is directed to the axis of the column and the nipples 12 are arranged in reverse manner, i.e. with closed ends lowermost. In Fig. 3b is shown a modified connecting nipple. A number of columns may be arranged in one cooling vessel and may be located vertically or horizontally in tanks through which cold water flows ; they may be in assemblies in parallel or in series. The nipples 12 are screwed or cemented into the lenticular elements 11 or fitted with conical locating surfaces. The elements are circular or polygonal in cross section. Specification 687,244, [Group XII], is referred to.
