Title: Improvements in liquid column internal combustion pumps or compressors
IPC: F04F1/16
Filed: 1922-04-24
Abstract: 205,523. Beardmore & Co., Ltd., W., Chorlton, A. E. L., and Rusdell, W. J. April 24, 1922. Explosion apparatus.-In an internal-combustion pump or compressor in which the explosive mixture acts on the surface of the liquid column, a buffer of inert elastic fluid is interposed between the liquid and the explosive mixture. The buffer may consist of products of combustion left in the chamber or scavenging air. The combustible mixture may be prevented from mixing with the buffer gas by introducing it through the inlets 1, 2 in a tangential direction, or by producing longitudinal partitions 5 in the chamber or a constriction 4<c>, which may be partly closed by throttling devices 8 adapted to be rotated to close the constriction more or less according to the pressure in the chamber below the constriction. The operation of the valves 8 may be correlated to the movements of the inlet valve 2. The buffer prevents splashing of the liquid intc the combustible mixture.

Title: Gas turbine safety coupling
IPC: F16D43/21
Filed: 1965-03-18
Abstract: 1,026,050. Clutches; couplings. GENERAL MOTORS CORPORATION. March 18, 1965 [March 24, 1964], No. 11484/65. Headings F2C and F2U. A positive clutch which disengages upon a predetermined overrun torque is in parallel with a friction slip clutch and a coupling which ensure complete separation of the clutch teeth upon disengagement. The clutch may couple a gas turbine engine to a propeller. As shown, a driving clutch member 123 has ratchet teeth 151 engageable with ratchet teeth 152 of a driven member 126 splined to an output shaft 114 connected to the propeller and to an engine starter (not shown). The teeth are urged into engagement by Belleville springs 144 rated to produce maximum force when the teeth are fully engaged. A control member 131 is fast with the driving clutch member 123 and has ramped teeth 164 engageable, with play, with teeth 169 formed on an axially slidable drum of a slip clutch 172 having friction plates splined alternately to the drum and to the output shaft and with a pressure plate 171 splined to the drum and urged by Belleville springs 186 to compress the clutch plates against backing plates 184 fixed to the driven coupling member 126. In normal operation the teeth 151, 152 are engaged. When a predetermined reverse torque occurs the driving clutch member 123 is moved rightwardly by the ramps of the teeth 151, 152, and as the teeth separate and the control member 131 is moved to the right the ramps of teeth 164 are brought into initial engagement with the ramped end faces of teeth 169, and the teeth 164 move up the ramped faces of teeth 169 until the clutch teeth 151, 152 are fully separated and stops formed on the teeth 164 engage the teeth 169. Differential movement of the clutch members 123, 126 is thus permitted with the clutch 172 slipping. The clutch member 123 is connected to a hub 115 integral with an engine shaft 111 by a lostmotion spline connection 116, 117 (Fig. 10, not shown) and by balls 120 in registering grooves 118, 119 which are inclined to the axis of hub and the clutch member 123. The depth of the grooves 118 decreases, and the depth of the grooves 119 increases, in the rightward direction of Fig. 8. When the clutch member 123 is engaged the balls 120 are shifted to the right centrifugally and are unloaded, the splines 116, 117 transmitting the entire torque. When the clutch member 123 shifts to the right to its disengaged position the balls 120 engage diametrically opposite sides of the grooves with slight relative rotation between the clutch member 123 and hub 115 and disengagement of the splines 116, 117 to permit free rolling action by the ball spline connection. In a modification (Fig. 1, not shown) the driving clutch member is integral with the engine shaft, being connected thereto by a resilient web permitting axial movement of the clutch member; also the teeth 169 of the coupling are formed on the pressure plate of the slip clutch instead of on the clutch drum.

Title: Improvements relating to pressure-responsive control devices
IPC: F02D1/00
Filed: 1966-03-16
Abstract: 1,112,705. Clutch control. DAIMLERBENZ A.G. 16 March, 1966 [18 March, 1965], No. 11532/66. Heading F2L. [Also in Divisions F1, F4 and G3] A control device for a liquid supply system is controlled in response to the vapour pressure of the liquid in a Venturi throat disposed in the liquid passage and designed so that cavitation is produced in the throat in the normal working range. An engine cooling water pump rotor 14 has an elevation 17 which forms a Venturi-like throat with the pump housing wall. A passage 18 communicates the cooling water vapour pressure to a pressure-responsive capsule 23 controlling the radiator-fan clutch 22. In operation clutch 22 remains disengaged whilst the engine is still cold and is engaged when the vapour pressure of the cooling water rises due to an increase in the cooling water temperature. The clutch 22 may be arranged to operate with a delay in relation to the temperature rise and the maximum speed of the fan may be limited by known devices. The vapour pressure may act through a servo-device by acting via pipe (11), Fig. 3 (not shown), on a piston (25), which controls the supply of a separate pressure medium from pipe (26) through pipes (27, 28) to the appropriate side of an operating piston (29), the non-pressure side of the piston being relieved via pipes (30, 31). The control device may be used for opening or closing radiator shutters, for operating a change-speed gearing, for actuating a sliding gear-wheel or a sliding shift member for a belt drive either alone or simultaneously with the engagement or disengagement of the radiator-fan drive. The pressure responsive member may operate an electric switch to control an electric servo-device (not described).

Title: Improvements relating to dust separators
IPC: B04C7/00
Filed: 1959-04-07
Abstract: 896,233. Removing dust from gases. HANDTE, S. April 7, 1959, No. 11747/59. Class 55 (2). A dust separator, suitable for use in factories or industrial plants for removing dust and other solid impurities from air or other gas, comprises a cylindrical housing, which contains a water sump and to which the gas to be purified is fed tangentially, an upwardly-directed suction pipe widening by way of an intermediate funnel to form a cylindrical portion of larger diameter arranged axially within the housing above the water sump, and a gas-guiding screw which is arranged above the intermediate funnel within the cylindrical portion, which screw imparts a gyratory motion to the waterladen gas flowing upwardly throuh the suction pipe and deflects the'water-laden gas so that the particles of water are deposited on the wall of the cylindrical portion. If desired, the gas to be purified, on its way to the dust separator, may first pass through a preliminary purifier comprising an open-bottomed vessel equipped with a tangential inlet and a central suction pipe, this vessel being immersed to such an extent in a water sump that the water level in the vessel is only a little below the mouth of the suction pipe extending into the vessel. In the Figure, the gas to be purified enters the preliminary purifier V through inlet 25 mounted tangentially in the upper part of bell-like vessel 23 and leaves through pipe 22. Gas from the preliminary purifier enters dust separator H through tangentially arranged inlet 11 and leaves via the delivery side of fan 4. Both the preliminary purifier V and the dust separator H are mounted in a common water sump 26. Within the cylindrical housing 6, forming the lower part of dust separator H, there is installed a suction pipe 5 which widens in an upward direction by way of an intermediate funnel section to form a cylindrical portion 6<SP>1</SP> which constitutes the upper part of the housing. In this cylindrical portion 6<SP>1</SP>, there is mounted non-rotatably a singlespire screw 15, the spire of the screw being disposed around a cylindrical core 16 which terminates in a cone at both ends. Both the dust separator H and the preliminary purifier V may, if desired, be fitted with supplementary water spray nozzles. Sludge collecting in sump 26 may be removed with the aid of conveyer belt 27 and elevator 28.

Filed: 1930-04-14
Abstract: 341,356. Bracelets. OTT, E., 22, Durlacherstrasse, Pforzheim, Germany. April 14, 1930, No. 11765. [Class 43.] In expansible bracelets having one or more extensible elements linked up in the bracelet, an extensible link is formed from boxes b, c, slidably guided one within the other and having at least one pressure spring d, h, mounted in each box. The spring d pushes the boxes b, c, themselves one into the other, and the spring h pushes into the box c the end of the band g forming the main body of the bracelet. For use with a wristlet watch, an outer box b may be linked on each side of a watchcase a with the bracelet body g forming a single closed band, or a double extensible link may divide the bracelet body in two parts directly linked to the watch. The spring d is stronger than the spring h, so that the latter only is brought into action when adapting for differing arm widths, and the total extension is used only when the bracelet is slipped over the hand. The springs may be mounted above or below or around the slidable parts, and the boxes may be constructed of tubular closed bodies or of guide parts.

IPC: H04B1/64
Filed: 1958-04-14
Abstract: 859,602. Volume compression and expansion. GENERAL ELECTRIC CO. Ltd. July 14, 1959 [April 14, 1958], No. 11847/58. Class 40 (4). Several channels share a single compressor or expander on a time-division bases. As shown, signals are fed to the compressor 2 from channels 1A, 1B ... in succession by an electronic switch 5, whence they are distributed to the channels 3A, 3B ... by switch 6. Each output channel feeds a low-pass filter 7 and detector 8 which produces a signal following the syllabic changes of level. These are fed by switch 9 at the appropriate instant to the compressor 2 to effect the compression appropriate to that channel. Since the intelligence of any output channel is available either in the audio range or as side-bands of the switching frequency or its harmonics these may be selected by appropriate different filters for the different channels, and combined for frequency multiplex transmission. Alternatively identical filters 10 may select the same side-band, say 8-12 kc/s., which may then be fed to modulators 11 fed by appropriate frequencies, and filtered at 12 for combination in the frequency multiplex transmission line 13. By so choosing such a side-band rather than the audio signal, the construction of the filters 12 is simplified. Supervisory signals may be injected at 14. An expander operating on the same principles, but with the control signals for the expander being derived from the input signals is also described, Fig. 2 (not shown). Separate signals indicating the degree of compression may be sent if desired.

Abstract: 981,222. Gauging apparatus. SIGMA INSTRUMENT CO. Ltd. June 8, 1961 [April 4, 1960; May 17, 1960], Nos. 11879/60 and 17425/60. Heading G1M. A machine for checking a number of dimensions of a workpiece 104, such as a compressor blade, includes two adaptor plates 101, 102 which can be removably secured to the machine and on which are removably mounted plates 120, 121 each carrying a group of measuring tips 103 for engaging both sides of the workpiece. Further plates such as 120, 121 with measuring tips may be provided for checking a number of cross-sections along the length of the blade. The tips 103 are adjustably secured to vertically movable slides 114 and may be exchanged for others when desired. Each group of slides is mounted in a frame 115 fixed to the plate 120, or 121, as the case may be, some of the slides being fixed in position to locate the workpiece vertically, while the others are spring-loaded towards the workpiece. Errors in the workpiece dimensions lead to movement of the tips away from a standard position, this movement varying the separation of a pneumatic gauging heat from an an@ (these are not shown) associated with each tip. For differently shaped blades different sets of measuring tips are used, the adapter plates 101, 102 being removed from the machine to facilitate the changing operation. The workpiece may be located horizontally by means of a fixed and a resilient stop (a simpler embodiment) but in the embodiment shown, stops 129, 137 are both movable. The stop 129 is rigid with the plate 120, which is movable, with its measuring tops, to left and right in the figure, on spring parallelogram linkage 124 connecting it via bridge 123 to the adaptor plate 101. Plate 121 is similarly mounted and urges stop 129 to the left, via the block 134, under the action of spring 152 which also urges block 144, 143, and hence stop 137, to the right. The corresponding relative movement of the anvils 147 and 160 provides a measurement of the blade width at the cross-section in question. The plate 102 is lowered for measurement towards plate 101 by mechanism provided in the machine. During this action, wedges 161 and 162 are withdrawn from between studs 148, 149 and 155, 159, respectively. In an inoperative position of the plates 101 and 102, the wedges move these studs apart, against the tension of spring 152, so that the stops 129 and 137 are retracted to allow removal of the workpiece. The Specification also describes other constructional arrangements, for example, the slides in one, or more, groups may be mounted for oblique movements. Specifications 724,205, 724,228 and 845,753 are referred to.
