Filed: 1925-02-06
Abstract: 248,538. Getriebe & Motoren Ges. Waap & Kayser, and Waap, F. Feb. 6, 1925. Fixed-abutment type; regulating.-An hydraulic variable-speed gear comprises a body 1, Figs. 1 and 4, fixed to the driving shaft 3 and carrying pivotally mounted vanes 11, working in an annular chamber 13 in the driven casing 5 provided with an abutment 14. The vane spindles 10 are provided with cross-bars 12 acted on by springs 23 and co-operating with a segment 22 on the casing, to turn the vanes into recesses for passing the abutment. The speed is controlled by regulating the extent of protrusion of the vanes by projections 21 on a sleeve 20, which may be turned by a slidable sleeve 16 carrying a pin 17 which passes through a slot 18 in the shaft and inclined slots 19 in the sleeve 20. The cross-bar chamber forms a reservoir for liquid and is connected to the chamber 13 by a passage 39. In a modification, the vanes have flanges 35, Fig. 5, the right-hand flanges being provided with guide pins 36 received in a disc 37, the adjustable sleeve 20 is operated by a plunger 29 geared to a shaft 30, and leakage is prevented by stepped conical joints. In another form, the vane-carrying body consists of two portions 48, 49, Fig. 11<b>, which are forced apart by the pressure d-eveloped, so that pairs of surfaces 58, 59 and 64, 65 are pressed together to make tight joints and assist in driving the casing. Grooved wheels 74 on the vane spindles engage a rail 68, which is provided with a gap, so that the vanes may be retracted to pass the abutment by a cam 76 acting on the cross-pieces 77. The vanes may be shaped as shown in Fig. 13, and in order to secure a more even drive, the segment which operates the vanes so that they may pass the abutment, is provided with a longer running surface. The vanes may have borings 154, Fig. 15, arranged centrally or in their outer portions, or may be arranged reversely, and the annular pressure chamber may be enlarged near the abutment, so that even when fully projected the vanes are not in contact with it. After passing the abutment. the vanes may be turned out by springs 156, Fig. 14, which are depressed while the vanes are passing the abutment.

Patent GB-247557-A (GB)
Title: Improvements in and relating to variable gearing
IPC: F16H29/04
Filed: 1926-02-09
Abstract: 247,557. Getriebebau-Ges., (Assignees of Wolf, K.). Feb. 10, 1925, [Convention date]. Eccentrics used in variable-speed ratchet gearing consist of superposed eccentric discs 15, 14, Fig. 3, which are driven independently from the same shaft 1 and are adapted to be displaced relatively to one another, while rotating, to vary the throw of the eccentric, and therefore the speed transmitted. In the arrangement shown in Fig. 1, there are six inner discs 14 secured in progressive phases to the driving-shaft 1 and alternating with loose toothed wheels 13 driven through a countershaft 11 at the same mean speed as the discs 14. A relative angular displacement of the wheels 13 effects through pin and slot connections 20, 20a with the discs 15 the operation in unison of the six eccentrics. The shaft 11 is driven through a differential train 8, 6, 2, which has a normally fixed side wheel 2. The speed of the shaft 11 having been thus doubled, the gears 12, which it carries, are of half the size of the gears 13 to compensate. A displacement from rest of the wheel 2 effected manually through a worm 4 effects the required differential movement while rotating of the outer discs 15.

Title: Heat exchanger
IPC: F28D7/10
Filed: 1976-01-30
Abstract: 1528243 Heat exchanges PHILIPS GLOEILAIMPENFABRIEKEN NV 30 Jan 1976 [4 Feb 1975] 03748/76 Heading F4S In heat exchange apparatus in which a fluid such as air flowing in one passage 6 is heated by flue gas flowing in an adjacent passage 7 and wherein said passages are separated from each other by a heat conducting wall 5, the wall comprises two series connected sections 5a, 5b, and in that section 5b containing the flue gas outlet from the heat exchanger said wall is hollow and the space 10 therein contains a volatile fluid which, by a continuous evaporation/condensation cycle, transfers heat through the wall and also acts to equalize the wall temperature along the wall in the direction of fluid flow thereover in said section. The intention is to maintain the flue gas contacted surface of the wall adjacent the flue gas outlet above the dew point temperature of the flue gases. The apparatus may comprise either single passages for the flue gas and air streams, or an intercalated plurality of flue gas and air passages (Figs. 4, 4a, 4b). In this form the respective spaces (23) containing the volatile fluid are interconnected. Circulation of the volatile fluid during the evaporation/condensation cycle may be effected by capillary material in said space or by capillary grooves on the wall surface of said space. Suitable capillary materials suggested are fine mesh gauze and porous ceramic material. The volatile liquid may comprise water or an organic liquid such as acetone, benzene, ethanol, propanol, or butanol.
Patent GB-758118-A (GB)
Title: Fluid dispensing apparatus with automatic flow arresting means
IPC: B67D7/46
Filed: 1954-02-09
Abstract: 758,118. Dispensing liquids. AVERYHARDOLL, Ltd. Feb. 9, 1954 [June 26, 1953], No. 3815/54. Class 116 [Also in Groups XVII and XXIX] A fluid dispensing apparatus with automatic flow arresting means comprises a manually opened throttle which closes when the fluid flow falls below a predetermined rate; a valve in series with the throttle urged to close by the flow; a bypass to the valve permitting a flow less than the predetermined rate; means to hold the valve open and means to release the holding means when a predetermined quantity of fluid has been delivered. On depressing and releasing lever 34, Fig. 1, auxiliary valve 29 opens a by-pass via orifice 30, seat 28 and passage 27 in piston 24 so that fluid supply pressure in pipes 1, 2, 3 via open valve 8 acts on the piston and opens main valve 26. When a predetermined volume of fluid has passed the flow meter 6 and completely rotated a cam 14 via spindles 11, 13 and gears 12, fluid pressure is able to close the valve 8 against spring 36 since, through connection 10, 19, 20 the lever nose 22 is thrust off the edge of the cam into a slot 15 uncovered by a shutter 16 engaged by the nose. A by-pass 37 in the closed valve 8 permits a small flow which is insufficient to prevent the valves 26, 29 closing. On closure of these valves, valve 8 reopens and nose 22 is ready to ride over the shutter on to the cam edge for another delivery of a predetermined quantity of fluid. The gears and/or the cam may be replaced or made adjustable to deliver selected quantities of fluid. In the embodiment of Fig. 2, the valves 29, 26 are opened as before and liquid flows into a tank 40 via valve 46 and pipe 55, and via a jet pipe 54 and by-pass pipes 41, 52, a pitot tube 51 in the path of the jet from pipe 54 ensuring that pressure together with a spring 48, behind a piston 47, maintains the valve 46 open. When a predetermined volume of liquid has raised the tank level to close the lower end of tube 41, the pressure behind the piston 47 falls and valve 46 closes under liquid flow. This allows pressure to be equalized on both sides of piston 24 so that spring 31 closes both main and auxiliary valves. The valve 46 may be a plug spring loaded to close the opening 49 and then pass therethrough to reopen it and drain pipe 44. Specification 724,064 is referred to.
