Title: Improvements in steam heating systems for railway cars
IPC: B61D27/00
Filed: 1924-10-21
Abstract: 246,211. Marks, E. C. R., (Vapor Car Heating Co., Inc.). Oct. 21, 1924. Heating vehicles.-In a steam heating-system for railway vehicles of the type in which the admission of steam to each radiator of the system is controlled by a valve which, when closed, provides a drainage outlet for the water of condensation from the radiator, the steam admission valve is operated by a motor and is automatically moved to a closed position so as to open the drainage outlet, which is connected to the inlet end of the radiator, upon the cessation of steam in the supply pipe. In the arrangement shown in Figs. 1, 2, and 3, the invention is applied to a system in which a main heater A is controlled by a valve in a casing E and an auxiliary heater B is controlled by a valve in a casing F, these valves being automatically operated by the pressure of the steam, but the auxiliary valve being capable of operation only when the locomotive is coupled and the air pressure in the signal line P operating through a pipe N, and piston 80, Fig. 2, opens a pilot valve 86. In this way, moderate heating of the vehicles can be accomplisbed by supplying steam from a terminal when the vehicles stand in a yard, but full heating is normally only obtainable when the locomotive is coupled. Each valve casing E, F, Fig. 3, contains a rotary valve 37 having a drainage port 47 which registers with a port 48, Fig. 2, in the valve casing only when the valve 37 is closed. Opening and closing of the valve is effected by the action of steam pressure in one direction and of a spring 75, Fig. 2, in the other direction upon a piston 71, the stem of which has a projection 68 engaging a spiral groove 67 in the stem of the valve 37. The connection between the valve 37 and its stem can be released by a push rod 78, allowing hand actuation of the valve, but the connection is automatically restored when the steam pressure again causes rotation of the valve stem. A thermostatically-controlled -valve in a regulator D regulates the amount of steam admitted to the radiators. In a modified arrange. ment, Fig. 5, the opening and closing of the valve 137 is controlled by two electromagnetic relays 107, 108, and the two heaters A, B are both either in use or out of use, the temperature to which the vehicle is heated being determined by low and high temperature thermostats 112, 113, the latter of which is operable only when air pressure in a signal line 175 acting on a piston 176 breaks contact between fingers 147 and a contact ring 148 and throws the low temperature thermostat out of use. In order to effect a closure of the valve 137 when the steam supply ceases, thus allowing the condensed water to drain away, an expansion-type thermostat R is fitted on the supply pipe 104, Fig, 7, so as to complete a circuit through contacts 186, 187, short-circuiting the relay 110 and so energizing the relay 107 which closes the valve.

Title: Process for the production of hydrofluoric acid
IPC: C01B7/19
Filed: 1961-07-11
Abstract: In a process in which HF is prepared by reacting fluorite with conc. H2SO4 (in 1) and the HF containing gases produced are washed with condensates from the same, the HF gases produced as above are passed through a first device (2) for separating suspended solid matter from the gas, some of the high-boiling impurities (mainly H2SO4 and HSO3F) of the gas being condensed and separated by contact with a counterflow of condensates from a fifth device (7).  The so treated gases then pass through a second device (4) which causes the gas to partially condense to form condensate and to further condense by the gas being directed against the liquid surface of the said condensate, then pass to a third device (5) for separating sulphur from the gas by means of an iron-catalyzed reaction (e.g. iron mesh) between SO2 and <PICT:0999137/C1/1> H2S impurities, then to an indirect cooling device (6) for cooling with a counterflow of water.  The condensates from the second, third and fourth devices are then combined and the gas treated with the combined condensates in the said fifth (7) to hydrolyse the fluosulphonic acid present in the gas, and finally the purified HF is liquefied (10).  Uncondensed gas from the sixth device may be washed with sulphuric acid (11) and the sulphuric acid, fed to the initial reaction (1).  The sulphuric acid may be mixed with oleum prior to the initial reaction. Water, oleum or dilute HF may also be added to the fifth device.  Numerals refer to Fig. 1. Fig. 1.

Abstract: 322,473. Morris Commercial Cars, Ltd., and Hamill, W. W. Sept. 1, 1928. Steering-gear; deflectable axle-ends and intermediate connections therefor.-A shock-absorbing device providing a break in the metallic path from the stub axles to the steering hand-wheel comprises two coaxial parts connected by a flexible non-metallic medium and adapted to absorb shocks by a relative rectilinear movement. The shock-absorber may be situated in the drag link or the track rod or in both. In the construction shown in Fig. 1 a rubber, leather, or like annulus t is held in housings b, g by three bolts connected to the housing band by alternately-spaced bolts o on the housing g. A plate l is secured to the housing g by a nut m and fits in a groove in the flexible annulus t. The housings b, g are adjustably screwed to the two parts of the drag link or track rod and are locked thereto by nuts f, j. In a modification two threearmed spiders may be used instead of the housings b, g. In the construction shown in Fig. 2, flexible washers c<1>, separated by plates d', are threaded on a spindle a<1> between collars h<1>, i<1>, and are gripped in a housing b<1> between a snoulder j<1> and a cap k<1>. Holes or depressions l<1> are formed in the plates d' to allow of deformation of the flexible washers. The two coaxial members may be positively guided relatively to each other, and the amount of movement may be limited in case of failure of the flexible coupling. The flexible members may be of laminated textile construction, the threads in adjacent layers being arranged at different angles, and the bolt holes being formed by separating the threads with a pointed tool.

Title: Improvements in engine starters
IPC: F02N15/06
Filed: 1923-10-10
Abstract: 205,799. Bendix, V. Oct. 19, 1922, [Convention date]. Turning-gear.-In an electric or other starter comprising a driving member mounted on a rotatable shaft and moved axially into engagement with an engine member on rotation of the shaft, means are provided for relieving the driving member from the enforced axial movement if the angine turns backwards. The driving-pinion 7 has a smooth bore and is moved axially by a nut 8 threaded on a hollow screwed shaft 5 surrounding the shaft 2 of a starting- motor 1 and connected to the shaft through a drive spring 9. The axial movement of the pinion is opposed by a light spring 12 between a stop 6 and a slidable sleeve 13. Between the nut 8 and the face of the engine fly-wheel 14 is a roller 15, the stem 16 of which is carried by a bracket 18 pivoted on a fixed bracket 20. A spring 24 connecting the brackets 18, 20 holds the roller 15 normally out of contact with the fly-wheel, the bracket 18 abutting against a face 23 on the bracket 20. The roller 15 is normally depressed by a spring 17. When the nut 8 and pinion 7 are moved to the right into the starting positon by rotation of the shaft 5, the conical faces 26, 25 of the nut and the roller 15 are in contact and the roller 15 is in contact with the flywheel. If the flywheel then turns backwards, it drives the roller 15 and nut 8 in such a direction as to the nut backwards on the shaft 5 and out of driving engagement with the pinion 7.

Filed: 1962-07-03
Abstract: 947,296. Grinding. ROLLS-ROYCE Ltd. July 3, 1962, No. 25348/62. Heading B3D. Two members 6, 7, Fig. 1, joined together by a strip 16 overlapping both members are separated by grinding away the strip without removing material from either of the members. As applied to the compressor casing 7 of a turbo-jet engine circumferential strips 16, 17 join portions 6 and 8 to the casing 7 which is itself formed of separable abutting halves 9, 10 joined at diametricallyopposed longitudinal edges 12 by overlapping strips 15. The assembly is mounted on a frame 21 having support rollers 22 and manually-operated frictional contact roller 24 whereby the assembly may be rotated about its axis 14 during grinding of the strip by a wheel 27 carried by a support 42 pivotable about a horizontal axis normal to the axis 14. The support 42 is carried by a first slide 30 by which the wheel and its compressed air motor 51 may be moved towards and away from the work and by a second slide 29 traversable by a lead screw operated by a handle 32. The wheel support 42 is resiliently urged towards the work by springs 49, Fig. 2, but may be retracted therefrom by sliding along the square shaft on which it is mounted for pivotal movement about the shaft axis, a clamping screw 39 being provided to secure the shaft and wheel in the desired angular position relative to the work. A depth gauge 54 having a clamping screw 56 is adjustable by a knob 57 to set the required depth of cut whereby the strip may be ground away completely, the gauge contacting the casing and preventing further grinding thereof. The wheel has a width at least equal to that of the strips 16, 17, and may be frustoconical. The apparatus may be modified to deal with work in which the axis 14 is vertical. The driving motor 51 is controlled by a valve 53.

Filed: 1924-10-24
Abstract: 233,602. British Sure Seal Co., Ltd., and Seymour, H. W. Oct. 24, 1924. Capsules and the like, applying.-In a machine for sealing bottles, jars and other receptacles with a flanged ring, the face of an adjustable stop is provided with an edge recess to receive one flange of the sealing ring and prevent it from spreading inwards whilst a second flange is formed. Secured to a support 2, Figs 1 and 3, on a hollow standard 1 is a stationary chuck 3 containing a series of contracting jaws 13 adapted to be moved on an adjustable stop 5, Fig. 6, provided near the edge of its head 6 with a groove 7 which engages the inturned flange of the sealing ring which secures the cover of the bottle &c. The jaws 13 are pivoted to a ring 12 adapted to be raised and lowered on the stop 5 by links 18 connected to arms 17 on the block and to a bell-crank lever 20 pivoted at 19 to the support 2 and actuated through a spring 23 by a rod 21 connected to a treadle 27 or a power-driven crank. The upward movement of the jaws 13 contracts them through the contact of their outer edges with a lip 9 on the chuck 3, the contraction causing inwardly projecting lips 16 on them to press the lower edge of the sealing ring inwards beneath the flange on the bottle. During this operation the sides of the jaws closely embrace the side wall of the ring. The position of the stop 5 is adjusted by a screw thread 10 on its stem, a spring- pressed pin 11 engaging grooves in it to lock it in the adjusted position. The treadle 27 may also operate simultaneously a bottle support 26 to raise the bottle and press it against the stop 5. Specification 17144/14 is referred to.

Title: Improvements relating to fluid shock absorbers
IPC: F16F9/48
Filed: 1927-09-28
Abstract: 302,738. O'Neill, J. H. Sept. 28, 1927. Pneumatic springs; fluid-friction vibration-dampers. - An upper telescopic cup 4 works in a lower cup 5 and carries a cylinder 9 which cooperates with two oppositely-acting oneway pistons 17, 18, so as to allow free movement away from the central position and retard return movement thereto. The apparatus is filled with oil up to about the level 27 and with compressed air supplied through a valve 13, leakage being prevented by packing rings 11 and 15. Any oil leaking past both packing- rings is retained in the circular groove 25 and is returned automatically past the packing-ring 15, whenever the pressure below the two rings is reduced below that of the atmosphere during operation. Each of the pistons consists of a valve disc or seat 21, an annular valve 22 and a perforated keeper 23, the valves being guided by pins 24. As the apparatus returns from the fully compressed position in which it is shown to the central position, the lower valve 22 is forced downwards, so that oil can only flow downwards through the restricted opening between the valve 22 and the cylinder 9, the movement thus being retarded. The reverse movement is free as the valve 22 then lifts and leaves a free passage for oil upwards through the perforated disc 13. The piston co-operates similarly with the upper piston for movement above the central position.

In valves having a sleeve-like diaphragm arranged to coact with a streamlined core to close an annular passage through the valve and wherein the diaphragm is anchored at one or both its ends to the housing and formed with longitudinal slits or recesses arranged alternately on opposite faces to produce a pleated bellows effect in a circumferential direction, the housing adjacent the or both anchoring points is formed with an axially projecting collar and the diaphragm with an enlarged unslit portion which when an unduly high pressure acts on the diaphragm in the closing direction closes the annular openings between the core and the one or both collars. In Fig. 1, the diaphragm 14 is anchored at one end 15 between housing parts 1 and 2 and supported on an axially projecting collar 21 formed on the part 1. Between the end 15 and a lip 17 engageable with the streamlined core 6 the diaphragm is enlarged and formed with longitudinal slits 19 on one face alternated with longitudinal slits 20 on its other face. Adjacent the collar 21 the enlarged portion is unslit and when an excessive back pressure acts on the diaphragm, which normally functions as a non-return valve, the enlarged unslit portion is forced into an annular opening between the collar and the core and so prevents the diaphragm being forced through the opening. In Fig. 5, the diaphragm 37 is anchored at both its ends and enlarged unslit portions 46 adjacent the anchorages are forced into annular openings between a core 35 and axially projecting housing collars 40 when the pressure of operating fluid admitted to an annular chamber 43 outside the diaphragm, is greatly in excess of the pressure of the controlled fluid.

Abstract: 1523827 Proximity sensors OWENSILLINOIS Inc 22 June 1976 [23 June 1975] 25874/76 Heading G1N An apparatus for sensing presence or absence of a glass container includes a 1 kHz. oscillator 10 and transformer 12 energizing a sensor element 20 through a resistance 18 of at least 100 megohms, preferably 1000 megohms. Presence of a container causes a voltage drop across the resistance which drop is sensed by a voltage follower 22. Sample and hold circuits 30, 31 sense the peak positive and negative excursions of the follower output. Difference amplifier 36 provides a signal indicative of the peak-peak value of the voltage output of the follower circuit. This signal is filtered and a fraction of it set by a voltage divider 45a, 45b is compared by comparator 46 with a signal from detector 54 representing the minimum level of the output from the voltage follower. Whenever the minimum level, determined during a period with no glass container present, is exceeded the comparator provides a  signal on conductor 62. The peak positive and negative portions of the follower output signal are sampled under the control of trigger circuits 60, 61 energized from a wave shaping circuit 56. The periods during which the minimum level is determined are set by signals on conductor 54.

Abstract: 1499599 Emergency stop gear for lifts INVENTIO AG 18 June 1975 [24 June 1974] 25973/75 Heading B8L A lift control device for limiting the speed of a lift cabin comprises a rope sheave 5 rotatable by interaction with a limiter rope 7 attache to the lift cabin, a cam 8 rotatable with the sheave 5, a follower roller 15 movable by the cam 8 upon rotation of the sheave 5, a brake 30 actuable on the limiter rope 7 and a brake actuating arm 24 operable upon the speed of the lift cabin exceeding a predetermined value. The roller 15 is mounted on a lever 9 pivoted at 10 to a fixed structure and having two limbs 9À2, 9À3, the brake actuating arm 24 being pivoted to limb 9À3 whilst a lift motor switch actuating arm 21 is pivoted to limb 9À2. The lever 9 is biased by a spring 17 for contact between the cam 8 and roller 15. Each of the arms 21, 24 is in its inoperative position held horizontal by a notch 9À5 on the limb engaging a lug on a washer 26 on the arm, the pressure of this engagement being adjustable by the setting of a washer 27 used to compress a spring 25 against the washer 26. Upon rotation of the sheave 5, the lever 9 is caused to oscillate by the cam 8, and due to inertial forces, at a first predetermined speed of lift travel, the switch arm 21, having a smaller force setting on the spring 25, is thrown out of its latched position and pivots downwardly to operate a switch to de-energize the lift motor. If the lift speed increases above the first said predetermined speed, the brake actuating arm 24, having a larger force setting on the spring 25, is thrown out of its latched position to operate the rope brake 30. The latter comprises a fixed jaw 31 and a movable jaw 33 mounted on a spring loaded parallel linkage 35, the arm 24 effecting movement of the linkage about pivots 38 to grip the rope 7. In the embodiment of Figs. 4 and 5 (not shown) the sheave cam causes vertical reciprocation of a lever carrying the brake and switch actuating arms. A further arm is provided on the brake for simultaneously displacing the switch actuating arm preventing braking without motor de-energization.

Abstract: 837,188. Multifocal lenses. PITTSBURGH PLATE GLASS CO. Aug. 13, 1958 [Oct. 7, 1957], No. 25985/58. Addition to 739,341. As improved upon by 749,169. Class 56. In forming and fusing a minor element in the major element of a multifocal lens by flowing molten glass from a continuous stream G into a countersink 6 in the major element blank 5 instead of severing the stream as in the parent Specification after each blank has been filled, the filled blank is quickly moved away (as by acceleration of a turret carrying the blanks) ; this pulls the stream out into a thin thread 8 which is thus connected to the next blank 51 filled during the next relatively slow transverse movement of the holder 3, the thin thread being subsequently fractured. This avoids the formation of any shear marks on the glass the subsequent polishing of the completed lens removing any trace of the connecting thread. Alternatively the supports for the blanks may be stationary and the molten glass delivery device made to move alternately quickly and slowly.
