Abstract: 638,067. Tubular heat-exchangers. ROLLS-ROYCE, Ltd. Jan. 2, 1947, No. 182. [Class 64(iii)] [Also in Groups XXVI and XXVIII] A gas - to - gas heat - exchanger for gas turbines comprises a casing having an inlet and an outlet for one gas, a hollow matrix of heat exchange tubes within the casing and having an inlet and an outlet connection for the second gas and at least three means connecting the matrix and the casing and supporting the matrix within the casing and permitting of relative uniform expansion the matrix and the casing along substantially straight lines radiating from a common focal point. The casing comprises flanged sections 10, bolted together, an inlet cover 11 and an outlet cover 17. The matrix 19 comprises an annular bundle of tubes extending between tube plates 21, 22 and supported intermediately by splitter rings 23. The tubes communicate at their inlet ends with a manifold 24 to which air is conducted by a pipe 25 connected to the air inlet duct through an elbow 26 and a connecting pipe. The outlet ends of the tubes communicate with an annular outlet manifold 28 having a pair of outlets 29 leading to the air outlet pipes 16. Flexible connections are provided between the air inlet and outlet pipes and the casing wall, (see Group XXVIII. The matrix is supported in the casing by three radially directed trunnions 35, (see Group XXVI), and by an axially directed trunnion 48, the axes of all the trunnions being disposed along lines radiating from a common focal point. Hot gases from the turbine enter through the opening 12 in the casing and are directed by a conical deflector 30 to the annular space between the matrix 19 and the casing, whence they are deflected across the tubes by a baffle 32, passing again across the tubes before being discharged through outlets in the cover 17. Air to be heated enters through the elbow 26, the pipe 25, the manifold 24, the tubes of the matrix, and the outlet manifold 28 to the pipes 16. In a modification the matrix is supported in the casing by radially directed connections formed on the air inlet header and by an axially directed connection, one of the radially directed connections between the matrix and the casing constituting the air inlet duct. The air outlet duct passes through the central space within the matrix and the hot gas inlet is formed in the wall of the casing. According to the Provisional Specification the casing may be lagged with aluminium foil.

Title: Pneumatic paper feeding apparatus in high speed presses, folding apparatus and the like
IPC: B65H3/08
Filed: 1921-01-07
Abstract: 156,720. Heenss, H. May 23, 1916, [Convention date]. Dropping-roller and like sheet feeds; sheet separators and carriers; pile supports.-Sheets are fed to printing, folding, and like machines at a high speed by means of suction nozzles which are moved into contact with the rear edge of the top sheet, of a pile, and then are tilted and moved towards a sheet-forwarding device on to which the separated sheet is deposited, the feeding of more than one sheet at a time being prevented by means of blasts of air delivered by nozzles arranged adjacent to the suction nozzles and tilted about the same axis as the nozzles. As shown, a pile table 6 is mounted above a feed-table 2 attached to supporting rails 3 from which depend guide tubes 4 for racks 5 which keep the table 6 at a constant level by means of mechanism involving a finger 47 which acts on the pile and worm gearing 9, 10, and pinions 7 on shafts 8 which engage the racks 5. The rear sheet of the pile is separated by means of a series of nozzles 27, Figs. 1, 3 and 6, depending from a tube 26 which is connected to a suction pump and is carried by levers 15 pivoted to a slide 14 which is moved along pivoted guides 13 by crank and link mechanism comprising links 17, 19, a triangular lever 18, and a lever arm 20 on a shaft 21 which is oscillated to an adjustable extent by a connecting-rod 23 adjustably connected to a reversing link 24 operated by a crank pin on a disc 25. In addition to its longitudinal movement along the guides 13, the slide is adapted to be raised and lowered by means also controlled from the crank-disc 25. The disc 25 oscillates levers 32 with pins 31 which support the guides 13, the front ends of the levers 32 being con. nected by a rod 47 which limits the motion of the levers 32 towards the pile, the rod 47 also acting in conjunction with known means for controlling the feeds of the pile table. A projection on the slide 14 limits its motion to the left, and then the continued movement of link 19, and lever 18, causes the suction nozzle 27 to tilt about the tube 26 to the position shown in Fig. 6. The air tube 28, air-blast nozzle 29, and deflector 30 move with the suction nozzle, and this effectively blows off any sheets adhering to the one raised by the nozzle 27. A pin 36 on link 19, in conjunction with a fixed cam surface, assists in raising the lever 18 to a vertical position to cause the tilting action described. The separator 27 carries the sheet in a rearward direction and when the suction is cut off, a dropping roller 42 feeds it into the bite of belts 38, 46, which carry it downwards, then under the pile table, and forwards to the feed-table 2. For dealing with sheets of varying widths the suction nozzles may be attached to tubes 48 which are adjustable laterally on an inner tube fitted with suction ports 49.

Abstract: 1286232 Cardiac glycosides KNOLL AG CHEMISCHE FABRIKEN 7 Jan 1970 [9 Jan 1969 31 May 1969] 770/70 Heading C2U The invention comprises compounds of formula (wherein either (i) R is CH 3  or CHO and one or two of R 1 , R 2  and R 3  is carboxylic acyl of at least two carbon atoms, the other(s) being hydrogen; or (ii) R is CHO and R 1 , R 2  and R 3  are all acetyl), and their preparation by acylation of proscillaridin or 19-oxoproscillaridin. When mixtures of products are obtained these are separated by column chromatography and/or Craig division. Triacylates of proscillaridin may also be formed by the reaction. The exact nature of the product is determined by the reaction conditions. The presence of a boron complexing agent (e.g. ortho- or metaboric acid) results in a 3<SP>1</SP>-monoacylate. The temporary ketalization of the 2<SP>1</SP>,3<SP>1</SP>-diol grouping during acylation results in a 41-monoacylate. The inventive compounds are said to be cardioactive and may be made up into compositions for oral administration.

Title: Wheel alignment testing equipment
IPC: G01B7/315
Filed: 1964-01-08
Abstract: 1,020,646. Testing wheel alignment DURA CORPORATION. Jan. 8, 1964 [March 25, 1963], No. 847/64. Heading G1X. Vehicle wheel alignment testing apparatus comprises wheel alignment responsive means for reception of the vehicle wheels to be tested as the vehicle passes over the means 12, means to differentiate between a number of prescribed wheel alignment conditions and a visual indicator to indicate the particular wheel alignment conditions of the wheels under test. The wheel alignment responsive means comprises two tread plates 14 each including a wobble plate 22, Fig. 2 mounted for limited movement, transverse to the direction of vehicle travel, on rollers 24. As a vehicle is driven over the apparatus any side slip of the vehicle wheels due to misalignment will be transmitted to and will displace the wobble plates 22. These plates are interconnected by a linkage 28 and are linked to a rod 36 to move an indicator pointer 46, Fig. 5, within a pedestal in accordance with the displacement of the wobble plates 22. The pointer 46 also carries a disc 50 having cam surfaces 64, 66, 68 to actuate switches 52, 54, 56 respectively. Slight movement of the disc 50 will actuate the switch 52, greater rotation of the disc will actuate the switch 54 and any serious misalignment will actuate the switch 56. Each of these switches are connected in a circuit to illuminate respective areas of the visual indicator. As the greatest deflection of the plates 22 occurs as the vehicle wheels leave the plates an air hose 162 is disposed at the trailing edge of one plate 22 and this is connected to a pressure switch which prevents closure of the circuits to the switches 52, 54, 56 until this point of maximum deflection. The switches 52, 54, 56 also control a recording device 20 which contains three solenoid operated hole punches 140, Fig. 7. These punches punch appropriate holes in a card 88a fed from a stack 88 in a holder 86. The cards are fed singly by a solenoid operated pusher 100 and electrically driven feed rollers 94 into place beneath the punches 140. In this position the card actuates a switch 126 to release the pusher 100 and stop the drive to the feed rollers 94. After the test the appropriately punched card is withdrawn and the switch 126 causes another card to be fed into position beneath the punches. The electrical circuit of the apparatus which is described in the Specification includes a manual or time-switch operated reset mechanism, so that the indicator 18 will remain operative until the reset is actuated. An alternative form of cam disc 50 is described, requiring only two switches and a semi-automatic recording and card punching device is also described in which a card is inserted into the device before each test, the punching being carried out as previously described.
