Title: Adjustable pit prop
IPC: E21D15/10
Filed: 1931-07-14
Abstract: 378,175. Mine props. MACBETH, G., 21, Hill Road, Dykehead, Shotts, Lanarkshire. July 14, 1931, No. 20169. [Class 20 (ii).] Telescopic pit props of the type comprising inner and outer tubular sliding members in which adjustment is made by a rotatable cam sleeve mounted on the outer member, have pins placed in holes arranged spirally in the inner member, and the sleeve is resiliently mounted. The sleeve c, having upper helical surfaces f, supports cross pins el, e<2> projecting from some of a series of spirally arranged holes disposed at a pitch equal to the depth of the cam surfaces in the inner sliding member b, and a spring washer is interposed between the sleeve and the top of the outer prop member, so that it may give after the upper end r<1> of the prop has engaged the roof. The sleeve may be turned by levers or l. In a modification, Fig. 10, friction packing t<2> is interposed between the sleeve and the top of the outer prop member and a coned surface v<1> is provided on the sleeve. The top v<2> of the outer prop member may also be coned.

IPC: F16J15/48
Filed: 1922-07-24
Abstract: 205,239. Croasdell, J. F. July 24, 1922. Cup-leather sleeve joints.-Pipe-joints and the joints of two-part containers of the kind in which a liquid-tight joint is made by means of a flexible ring held by fluid pressure, the pipe or container sections being held together by a metal band, have this metal band D and the flexible ring A so arranged that even without fluid pressure the sides of the ring are forced outwards by the pressure of the metal band so as to bear against the pipe or container sections. This may be effected by shaping the top of the ring into a hump so that it bears against the band or by making the band with a ridge which presses on the ring, or by shaping both these members.

Title: Circuit arrangement for controlling the amplitude and mean  value of the force of an oscillation
IPC: G01N3/00
Filed: 1972-05-01
Abstract: 1385461 Automatic control of vibrations CARL SCHENCK AG 1 May 1972 [22 March 1972] 20213/72 Heading G3R A system for controlling the amplitude and mean value of an oscillating force in response to electrical measurement (by a strain gauge 2) of its upper and lower peaks comprises at least one store for the extreme values, means for calculating the actual amplitude and mean value from the stored values and comparators for comparing the actual values with desired values and for effecting control of the force. In the embodiment oscillatory loads are applied to a test piece 1 by hydraulic piston 10 to which fluid is admitted alternately to each side by valves 14, 15. A mean or initial force is also applied by a second piston 6 con - trolled by valve 23. Reservoirs 26 accommodate the fluid expelled from this cylinder by the relatively rapid movements of piston 10. The output of strain gauge 2 is amplified at 22 and entered into stores 27 and 28 which both retain  the highest and lowest values until reset, and from which a computer 29 derives in an unspecified manner signals Ai proportional to amplitude and Mi proportional to mean force, which are compared at 19, 20 with desired values As, Ms. The differences are periodically connected by switches 36, 37 (e.g. transistors) to undisclosed devices 38, 39 for adjusting the mean setting of fluid valves 14, 23. The switches are closed by a timing device 33 for a constant, predetermined brief time commencing shortly after the highest peak value is reached. This is determined by trigger circuits 42 ... 45 which respond when the actual force S is different from that in store 27. While the force is increasing these two quantities are equal (because the actual value is being entered) but when it starts to decrease the stored value remains high and the timer 33 is started by signals on NAND gates 46 and bi-stable circuit 48. At the end of a pre-set period (longer than the switching pulse) a signal from 33 resets stores 27 and 28 for the next cycle,

Title: Improvements in or relating to valves for regulating fluid flow
IPC: G05D16/10
Filed: 1953-07-24
Abstract: 738,911. Rotary pumps. VICKERS, Inc. July 24, 1953 [July 26, 1952], No. 20557/53. Class 110 (2). [Also in Group XXIX] A flow regulating valve of the type which discharges excess flow comprises a valve closure member with substantially balanced surfaces and enclosing completely a pilot valve which opens on the occurrence of excess pressure in a control chamber to vent said chamber through the closure member and cause the latter to open fully to discharge. In an embodiment, liquid from a reservoir 12 flows into a chamber 58, passes through a rotary vane pump 40 into a pressure chamber 64, and then passes through a restriction 102 to a selector valve 20 controlling a jack 31. The exhaust from the jack passes through valve 20 and flows to the reservoir 12 through passages 26, 76. The pressure in chamber 64, i.e. upstream of the restriction 102, acts directly on the right-hand face of a piston 72, and the pressure downstream of the restriction acts through passage 106 on the left-hand end of the piston. The piston is loaded by a spring 85 and it moves to maintain a constant pressure difference across the restriction, i.e. a constant flow through the restriction, by opening more or less a valve 83 (carried by the piston and shown closed) to allow excess fluid to drain from chamber 64 to the exhaust passage 76. When the jack reaches the end of its stroke, the pressure downstream of the restriction rises and opens a valve 94 to allow the fluid acting on the left-hand end of piston 72 to escape through the piston to the exhaust passage 76. The resultant excess pressure acting on the righthand end of the piston opens valve 83 fully and unloads the pump. The pump is driven by a shaft 46 which carries sliding radial vanes of which the outer edges run on a cam track. A loose plate 62 forced against the face of the pump by outlet pressure assisted by spring 85 is provided with outlet ports and with passages 70 which allow the pressurized fluid to act on the inner edges of the vanes to keep them in contact with the cam ring. Specifications 455,986, [Group XXIX], and 689,220 are referred to.

Patent GB-437543-A (GB)
Title: Method of and means for heating fluids particularly hydrocarbon oils
IPC: C10G9/20
Filed: 1934-07-16
Abstract: In the heating of a stream of fluid, particularly hydrocarbon oil, by passage through a direct radiant heat conduit comprising a row or bank of tubes arranged in the combustion and heating zone of a furnace, substantially equal heating is imparted to opposite sides of each tube by arranging the row or bank in such a manner that both sides of each component tube are exposed to direct radiation from the flames within the combustion and heating zone as well as from the hot walls.  As shown, a furnace 1 is divided by partitions 7, 8, into combustion zones 9, 10, 11 in the centre of each of which is located two adjacent rows 29, <PICT:0437543/III/1> 30 of staggered horizontal tubes.  Gas, oil or solid fuel burners 14 play through inclined ports 13 on to the side walls of each combustion chamber and the products of combustion pass through a horizontal duct 18 to a convection heating section 19 and thence via an air portheater 22 and flue 23 to a stack.  Air for combustion is supplied by a duct 24 leading via the preheater 22 to a header 25 from which travel ducts lead to the burners.  Oil to be heated is supplied as a split stream to two equal banks of tubes 35 in the zone 19, then serially through rows of tubes 32 adjacent the floor 6 in the zone 18 and finally, in parallel, through the rows 29, 30, in the zones 11, 10, 9.  The heating in the zones 9, 10, 11 may be regulated to give any desired temperature curve.  Thus, for the production of motor fuels from light distillates, oil preheated in zone 19 may be brought to conversion temperature in zone 11, zones 10 and 9 being soaking zones.  The different zones may be connected in any desired sequence and in series or parallel.  The furnace may be fired from the bottom.  The Specification as open to inspection under Sect. 91 states that the burner may be arranged to swivel so as to vary the inclination of the flames and the position of the hottest zone in the combustion chamber.  This subject-matter does not appear in the Specification as accepted.
