Inventor: BALDWIN RICHARD EVEREST
Filed: 1958-06-06
Abstract: 867,975. Typewriters &c. INTERNATIONAL COMPUTERS & TABULATORS Ltd. May 27, 1959 [June 6, 1958], No. 18231/58. Class 100(4) In a printing apparatus such as described in Specification 707,736 having a reciprocating stilus producing characters on a paper 1 continuously moving during printing multiple line spacing and long feed devices are provided. Two sheets of paper 1 laterally displaced are fed by pin wheels 2, 3 mounted on shafts 12, 13 and the operation of each is similar the former being described. A shaft 18 driven from the printing apparatus drives gear wheels 20, 21 fast on shafts 23, 24 and the gear wheel 22 freely mounted on a cam shaft 25. During line by line printing the shaft 12, Fig. 4, is driven for single line spacing by pawls 35, 36 actuated by cams 40, 41 on the shaft 23 rotating half a revolution per printing cycle. To give different speed feeds the pawls are aligned with either a ratchet wheel 26 or a ratchet wheel 27 which actuate alternately to give the continuous speed feed selected. To produce multiple line spacing feeds a pawl 42 engages one of the ratchet wheels and is actuated when a pivot arm 52 is moved from its datum position to engage a notch 51 of a control lever 44 by cams 48 on the shaft 23 acting through the control lever 44 the movement of which is settable by levers 54, 61, Fig. 2, which can be manually set on the scale 60 to give different lengths of feed and the latter is arranged to become effective under the control of an electromagnet 62, Fig. 5. Long feeds are made by a sector 78, Fig. 3, driving a pinion 29 on the shaft 12, actuated by a cam 82 on the cam shaft 25. The initial position of the sector 78 and thus the length of a feed it will effect on actuation is determined by a stop 81, Fig. 2, swingable into the path of its end 120 and the sector is moved away from the stop during feeding by the pawls 35, 36, 42 by their rotation of the pinion 29 under the control of a restraining device 103 and spring 113, Fig. 2, and when a long feed is required an electromagnet 90 is actuated to engage a clutch 83, 84, Fig. 5, so that the cam shaft 25 drives the cam 82, Fig. 3, to drive the sector 78 to feed the paper the remainder of a full feed to position the paper at a predetermined line. More than one stop 81 determining the length of a long feed can be provided and the stops are swung into and out of operative position by electromagnets 123. The position of the last line of a form is indicated by sitting a pointer 125, Fig. 2, which is clamped in its adjusted position on a shaft 126 thus also positioning contacts 129, Fig. 3. When a form is full a projection 130 of the sector 78 closes the contacts 129 to start a long feed to the next form but at the same time a second stop 81 is projected into active position a circuit being provided so that when this feed is completed a second long feed cycle is initiated which by the control of the second stop 81 feeds the form to the next item line.

Title: Improvements in or relating to Combined Evaporator and Boiler Feed-water Heating Apparatus for Power Plant.
IPC: B01D1/26
Filed: 1916-12-21
Abstract: 103,644. Griscom-Russell Co., (Assignees of Jones, R. C.). Jan. 26, 1916, [Convention date]. Feed-water, supplying and controlling. - A plant for supplying heated feed-water for steamboilers and also distilled water for make-up and other purposes, particularly on board ship, comprises means, such as a pressure-reducing valve, for regulating the temperature in the water evaporator, and thus adjusting the system to the load on the boiler. The plant comprises evaporators 6 generating steam, which flows to a combined condenser and boiler-feed heater 5 under a pressure which may be varied by a pressure-reducing valve 17 on the distilled-water outflow pipe 16. The salt water to be distilled is fed by a pump 21 through a preheater 7 receiving distilled water from the pipe 16 and a preheater 8 receiving the blow-off from the evaporators through a pipe 25, and enters the evaporators by a pipe 23. The boiler feed is withdrawn from a filter-box or storage tank 1 by a pump 2 and is forced through a heater 3 receiving exhaust steam from the auxiliary engines and thence through a pipe 4a to the condenser and feed-heater 5, passing to the boiler by a pipe 4<b>. The tank 1 is supplied with water of condensation from the main condensers, the heater 3, and the heating-coils of the evaporators, and also with a portion of the distilled water. In examples, the valve 17 is set at 43 lb. pressure for full load and at 50 lb. for cruising speed, the corresponding evaporator temperatures being 290 and 297‹ F. and the boilerfeed temperatures being 265 and 282‹ F.

Title: Recovery of olefin polymers
IPC: C08F10/00
Filed: 1957-06-11
Abstract: A process for the continuous polymerization or copolymerization of aliphatic mono-olefinic hydrocarbons in a reaction zone at pressures above 200 atmospheres followed by passage to a separation zone, in which upon the initiation of an unpredictable and uncontrollable decomposition in the reaction zone the hydrocarbon feed to the reaction zone is immediately stopped, the flow to the separation zone is stopped, the reaction zone contents are passed to a blowdown drum and the reaction zone is gasextracted into the blow-down drum to entirely remove impure material.  The flow of hydrocarbon feed to the reaction zone is then resumed, the polymerization restarted, and the flow from the reaction zone is recommenced to the separation zone. The pressure during the polymerization may be up to 4000 but is preferably from 800 to 1500 atmospheres and may be achieved through the liquefaction of the olefin.  A polymerization catalyst may be used, e.g. oxygen or air, hydrogen, diethyl, lauroyl, urea, tetralin, butyryl or benzoyl peroxides, persuccinic acid or alkali metal, alkaline earth metal or ammonium persulphates, perborates or percarbonates.  The olefin may be ethylene, propylene or isobutylene and ethylene may be interpolymerized with, for example, propylene, isobutylene, styrene; vinyl acetate, formate or isobutyrate; acrylic, methacrylic, itaconic, crotonic or fumaric acids or their esters, acid halides, amides or anhydrides; vinyl or vinylidene chloride, acrylonitrile, N-vinyl amides, vinyl ethers, divinyl formal, divinyl butyral or methyl vinyl ketone.  In the polymerization of ethylene chain terminators such as halogenated aliphatic hydrocarbons, saturated aliphatic or aromatic acids, esters, anhydrides, aldehydes, ethers, or alcohols, sulphonyl halides or sulphur halides may be used.  A process and apparatus for the continuous production of polyethylene is described in which the ethylene feed is obtained and separated from a C1-C2 refinery gas fraction.

Title: Apparatus for sorting plates used for the links of bicycle gear chains
IPC: B21L9/00
Filed: 1928-06-25
Abstract: 301,052. Seuthe, A. Nov. 25, 1927, [Convention date]. Parcelling by bundling.-Apparatus for sorting and stringing the bevelled side plates of bicycle chains comprises a reciprocating feeler with a bevelled end which separates from a succession of plates those which have the bevelled sides in the same position and feeds them to one or other of two holding and string- ing devices. The apparatus is shown in Figs. 2, 3, and 4. The plates are fed down a shoot 5 from the bottom of which they are delivered successively into a channel 19 by a reciprocating plunger 17 actuated by a lever 11 and cam 14. An escapement device allows passage of the plates singly in the shoot and consists of a rocking plate 8 with two fingers 7, 20 which enter the shoot alternately. The plate 8 carries pins 23, 24 by which it is rocked at the ends of the plunger movement, The plates are fed in front of a holder 3 and engaged by a spring- controlled plunger 27 with a bevelled end reciprocated in a guide 26 by a cam 29. If the bevel of the plate is directed downwards, the plunger lifts it out of the channel 19 and transfers it to the holder. The plates with the bevel upwards arrest the forward movement of the plunger which yields, and are finally moved into the holder 4. A pressure foot and spring controlled weight are arranged to hold the plates down during the transfer to the holders and to maintain the plunger in the guide 26 during its arrested movement. The stringing devices are contained in the holders 3, 4 and consist of vertically reciprocating pins 43, 51 which push the plates upwards past gravity or spring-operated latches 54, 57 on to wires 42, 42'.

Title: Improvements in adjustable spring-discharge lubricators for stiff lubricant
IPC: F16N11/04
Filed: 1945-07-18
Abstract: 614,399. Lubricators. THIRION, J. July 18, 1945, No. 18453. Convention date, April 7, 1944. [Class 12 (iii)] A spring-discharge lubricator for stiff lubricant has a flow regulator of rectangular cross-section and trapezoidal profile in side view with two adjustments, one a longitudinal adjustment serving to adjust the discharge orifice area for a given position of the piston and the other an adjustment whereby the rate of change (linear) of orifice area with respect to the discharge movement is adjusted. As shown in Fig. 1, the piston 1 of a lubricator effects its discharge movement under the action of a spring 2, the lubricant (grease) passing through a discharge-flow orifice area defined between the inner periphery of the rectangular entrance to a discharge pipe 4 and an adjustable trapezoidal block 6 housed in an open-sided groove in a rod 5 depending from the piston. It will be seen that the orifice area can be varied at any given position of the piston by a longitudinal adjustment and that by increasing the tilt of the block 6 the linear rate of increase of such orifice area with respect to the discharge movement of the piston will be greater. The increase of tilt is here shown effected by setscrews 11, 12. The longitudinal adjustment is effected by a milled nut acting on a threaded rod 8 attached to the block by a cap head 9. In the arrangement shown in Fig. 4, which is a composite figure, a trapezoidal block 15 moving through a nozzle plate 17 is screwed to an adjustable extent into a socket 14 in the piston 1 as shown at the right- and left-hand sides. Block members of different trapezoidal profile are inserted when it is desired to alter the rate of change of orifice area with respect to discharge movement of the piston.

Abstract: 1504863 Spray-producers F H POOK 23 April 1975 [27 April 1974] 18523/74 Heading B2F A spray gun to spray a mixture of air and liquid or powder, comprises a cylinder 1 having inlet holes 4, a piston 14 attached to a tubular rod 11, a spray nozzle 19, an air nozzle 12 on the end of the rod, cooperating with the spray nozzle, and a supply hopper mounting 2, so that when compressed air enters inlet holes 4 the piston is forced back against spring 18 moving the air nozzle away from the spray nozzle. The air enters the tubular rod through holes 13 and passes down to the air nozzle, the resulting air jet which issues from the nozzle entraining spray material from the hopper as it passes into spray 19. A flexible bell shaped seal 8 is provided for the rod and an adjustable screw 17 acts as a stop for the piston. The apparatus shown is contained in a rotatable barrel assembly, Fig. 2 (not shown) which has a pressure gauge and a handle assembly including an actuating button controlling a valve in the compressed air supply. The valve is never completely closed allowing a weak flow of air to prevent clogging of materials in the nozzles. In a modification, the compressed air may be supplied to both sides of the piston to control both strokes instead of spring 18, the actuating button then controls a changeover valve.

Abstract: 1,040,971. Revaporizing liquefied gases; heat exchange elements; refrigeration. NORMALAIR Ltd. May 3, 1965 [May 5, 1964], No. 18540/64. Headings F4H, F4P and F4S. A heat exchanger coil through which cold fluid flows from an inlet 1 to an outlet 2 comprises a first part 4, 5, 6 in thermal contact at e.g. points 15, 16, 17 with a second downstream part 8-14 disposed in a heat source, the arrangement being such that the fluid in the first part 4, 5, 6 is pre-warmed by heat exchange through the contact points with the warmer fluid in the second part, and the fluid in the second part is alternately cooled by heat exchange with the first part and warmed by the heat source. The heat exchanger ensures that the temperature of the fluid flowing in the second part does not fall below a minimum temperature. The heat exchanger may operate as a liquid oxygen vaporizer using ambient air as the heat source without frost forming on the second part and thereby impairing its efficiency. The heat exchanger may also operate as a cooling coil for chilling water using liquid or gaseous ammonia as the fluid and the water to be cooled as the heat source, again without ice being formed on the second part.

Title: Stays for windows and other hinged and pivoted articles
IPC: E05C17/28
Filed: 1934-06-23
Abstract: 440,420. Stays. CRITTALL MANUFACTURING CO., Ltd., and WALKER, F. P., 210, High Holborn, London. June 23, 1934, No. 18622. [Class 65 (i)] In a window or like stay comprising a bar attached to one member and slidable relatively to a guide attached to the other, the bar is formed with a groove having stepped limiting surfaces for selective engagement by a detent on the guide, so that the opening of the window may be limited to a greater or smaller angle according to the position of the detent. Means may be provided for preventing opening of the window altogether. The detent can preferably only be moved from one position to another when the window is closed. In the form shown, the bar B is fixed to the window and the guide C, sliding on the bar, is attached to the frame by a stay-bar A having a pivotal connection at each end ; the guide C has a shoe K and clamping screw L to hold the' window in any position. The bar B has in its underside a groove 10, of the form shown in Fig. 6, which is engaged by a lug 1 carried by a disc 14 rotatable on the guide C, the lug working in an arcuate recess 16 in the guide permitting its movement from one side of the groove 10 to the other. The end 4 of the groove provides one limiting surface, and another, 2, is provided by a projection 11, on one wall of the groove, which also provides a dividing rib 12 between the parts of the groove leading to the two limiting surfaces. The inner end 13 of the groove is formed as a cam surface to guide the lug 1, when the window is closed, to the position in which it will engage with surface 2, so that unless the lug is moved when the window is opened the opening is very limited. This effect may alternatively be produced by spring means, and the arrangement may be such that the lug is normally opposite the longer arm of the groove. The window may be locked in the closed position by a transverse slot as shown dotted at 19, the lug being spring-biassed to enter this slot, or, according to the Provisional Specification, by a notch in the end of the rib 12, the lug being normally moved by cam surface 13 or spring to the necessary position to engage this rib. In a modification, the groove consists of two parallel grooves connected at the inner end by a transverse passage, the two grooves being of different lengths or one of them having an intermediate stop, and the detent is a lug on a member slidable transversely in the guide. The detent may be spring-pressed to one position, and a catch may be provided to hold it in the other position when required. The device may be adapted to hold the window closed in ways similar to those described above.

Title: Improvements in or relating to Hoods or Covers for Motor Road and other Vehicles.
Inventor: RAPSON FREDERICK LIONEL
IPC: B60J7/12
Filed: 1918-11-15
Abstract: 134,368. Rapson, F. L. Nov. 15, 1918. Hoods for motor-vehicles are adapted to be raised by rotating a screwed shaft along which travels one or more blocks connected by cables to a frame member of the hood. According to Figs. 1 and 4, a screwed shaft 13 mounted in bearings 12, 22 carries at each end a block 8 connected by a cable 9 passing over a pulley 10 to an arm 1 on the main hoop-stick 3. The shaft and blocks are preferably formed with co-operating helical grooves for the reception of antifriction balls or rollers which are circulated through a passage in or through a spiral tube on the blocks. A wick lubricator may be fitted on the tube to lubricate the balls. The blocks are prevented from rotation by projections 16 thereon, which pass through a slot 17 in a covering-tube 18. The shaft is rotated by a detachable winch handle 15, which may be similar to that described in Specifications 116,995, [Class 79 (iii), Motor-vehicles, Arrangement &c. of parts of], and 119,719, [Class 144 (i), Wheels &c.]. Springs 23 may be provided for returning the blocks when the winch handle is released at the end of the raising operation, so that the hood is free for lowering by hand when desired. The arm 21 for supporting the hood in the lowered position may be integral with the bearing 22 for the shaft 13. The shaft may instead be rotated by bevel-gearing arranged at the middle of its length, the winch handle being inserted in the back of the vehicle. As shown in Fig. 8, the cables are connected to a single block 28 which traverses a vertical shaft 29, rotatable by bevelgearing 30. In this case, the folded hood is housed in a recess 33 in the body, a plate 34 attached to the front hoop forming a lid for the recess. The covering-material of the hood, which is attached to the outer wall of the body when the hood is raised, is adapted to be detached from the body for disposal in the recess.
