Title: Improvements in and relating to rotary-chamber drying machines
IPC: D06F58/22
Filed: 1931-09-10
Abstract: 386,711. Air-filters. CHERRY TREE MACHINE CO., Ltd., Cherry Tree, and DOWELL, G., 7, York Terrace, Shear Brow, both in Blackburn. Sept. 10, 1931, No. 25367. [Class 8 (ii).] In a rotary drying-machine for the drying of goods by means of a current of warm dry air, the screen for removing particles of fluff from the air leaving the machine is cleansed by a wiper or squeegee so connected with the mechanism for rotating, starting, stopping, or opening and closing the revolving chamber that the one cannot be operated without the other. Preferably, the normal operation of the said mechanism automatically moves the wiper over the screen, but the manual moving of the wiper may be an essential preliminary to the operation of said mechanism, or the wipers may continuously pass over the screen under the influence of a rotating part of the machine. In one form of the apparatus, a rotary cylinder c has an air inlet b and outlet e, the air passing through a screen a between the aperture d and outlet e. The wiper or wipers j are carried on bars i attached to arms h fitted to a shaft f so linked to the main door c<1> of the machine that on opening the door, the shaft moves the wiper down over the screen and removes the fluff; on closing the main door, the wiper bar is moved upwards to the original position. In a similar way, the wiper may be coupled to the starting lever. In another form, the main door cannot be opened until the wiper has been moved from top to bottom of the screen, and cannot be closed until the wiper has been returned. The wiper bar i may itself be rotatable, being so connected to the shaft f that on moving the shaft, the bar and brush are rotated in a direction opposite to that caused by rolling on the screen. In another form, the wiper is moved to and fro by a link attached to a ratchet wheel driven from the main trunnion of the revolving cylinder.

Title: A process for improving the products of the synthesis of hydrocarbon oils from carbon monoxide and hydrogen
IPC: C07C9/14
Filed: 1938-08-31
Abstract: 519,722. Motor fuel ; synthetic oils. SYNTHETIC OILS, Ltd., and MYDDLETON, W. W. Aug. 31, 1938, No. 25496. [Class 91] [Also in Group IV] The Diesel oil fraction, boiling mainly between 180-330‹C. of the hydrocarbons obtained by synthesis from 1 vol. of carbon monoxide and 1-1.5 vol. of hydrogen, is segregated and treated with hydrogen or a gas containing free hydrogen in presence of a hydrogenating. catalyst and under conditions similar to those employed in the synthesis. As the improvement in cetene no. is less pronounced in the higher fractions only a lower sub-fraction of the Diesel oil may be treated and then be recombined with the heavier untreated sub-fraction. In an example, a 200-250‹C. fraction of a 200-330‹C. Diesel oil is re-admitted to the catalytic chamber along with hydrogen, blue water-gas, or coke oven gas, the temperature being the same or not more than 20‹C. higher than in the synthesis ; the product is fractionally distilled to separate newlv formed synthetic products, and is added to the untreated 250-330‹C. fraction of the Diesel oil. The synthetic process may be that described in Specification 491,778.

Title: Improvements in or relating to echo sounders
IPC: G01S7/527
Filed: 1946-08-27
Abstract: 624,442. Echo sounding and distancemeasuring apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., TWATT, J., and GRAY T. Aug. 27, 1946, No. 25674. [Class 118 (ii)] A subaqueous echo sounding or like receiving system comprises means for differentiating between received pulses of more than a pre-determined duration with relation to received pulses of shorter duration so as to favour response to the former. The incoming signals are received on a normal high-frequency amplifier (not shown), the last stage V1 of which is transformer-coupled to a full-wave rectifier A, which develops an output potential across a resistor R1 shunted by a smoothing condenser C1. This potential is applied via resistor R2, transformer T2 and an integrating circuit R3, C2, to the grid of a valve V3, noise pulses of an excessive amplitude being byepassed to earth by a diode V2. The output of V3 is then applied to a discharge trigger tube V4, or other indicating or recording means. With a damped magneto-strictive projector having a resonant frequency of 14 kc/sec. and a decay rate of 40 dbs/sec., the integrating circuit R3, C2 is given a time constant of 1.5 ms. Noise pulses will in general give rise to a 14 kc/sec. vibration in the receiver which decays by 40 dbs. in 1 ms. and therefore will not last long enough to raise the potential of condenser C2, and hence of the grid of V3, sufficiently to cause V4 to strike. It is shown that received echo pulses, because of the divergence of the transmitted beam, will in general have a sufficient duration to cause the tube V4 to strike (e.g. 2 ms. at 200 fathoms, or 5 ms. at 500 fathoms). The time constant of the integrating circuit may be adjustable and a plurality of such circuits may be provided in cascade.

Patent GB-329921-A (GB)
IPC: B25D9/20
Filed: 1929-08-28
Abstract: 329,921. Chicago Pneumatic Tool Co., (Assignees of Nell, G. M.). Oct. 25, 1928, [Convention date]. Percussive drills.-The fluid is distributed by a hollow valve having four differential areas upon which the pressure acts to lock and reverse the valve. The blow of the piston 4 is shown imparted through an anvil block 7 slidably mounted in a guide 8. The cylinder has one or more transverse annular grooves 9 connected to atmosphere by one or more ports 10. The rear of the piston chamber is closed by a plug 11 provided with an extension which enters a recess in the piston provided to reduce its weight. The valve chamber is arranged close to the cylinder to reduce the length of the passages. The fluid to return the piston passes through the valve and chambers and passages 16, 17, 18, 18a. The left-hand end 19 of the valve is smaller than the right-hand end 20 thereof, and a shoulder 21 is provided so that sum of the areas 19, 21 exceeds the area 20. The valve also has a flange 22 with a forward shoulder 23. The areas 20, 23 together exceed the areas 19, 21. The faces of the flange 22 are vented to atmosphere by a large vent 24 and a restricted vent 25 respectively. A piston-controlled cylinder passage 26 extends to the area 23. The passages 26, 25 form an auxiliary rear exhaust to the main cylinder. A forward auxiliary exhaust to the main cylinder through passages and chambers 18<a>, 18, 17, 16, groove 27 and the chamber 9 and controlled by the valve is also provided. In the position of the valve shown in Fig. 1, the pressure fluid is acting on areas 19, 20, 21. When during its forward motion, the piston uncovers port 26, fluid pressure builds up on area 23 and the valve is shifted rearwardly and cuts off the motive fluid before chamber 9 is uncovered. The pressure on areas 21, 23 is relieved and the valve completes its movement and is held to the left since the area 20 exceeds the area 19. The piston is reversed. After the exhaust is closed, compression pressure builds up on area 21, and when the pressure on areas 19, 21 exceed the pressure on area 20 the valve is moved forwardly. The piston momentum completes the valve movement and the main exhaust is opened. A radial leakage port 30 may be provided to speed up the building up of pressure on area 21. In each direction of motion, the valve is reversed before the main exhaust is opened.

Abstract: 1,259,857. Spraying devices. M. J. GOODALL. 13 May, 1970 [23 May, 1969], No. 26321/  69. Heading B2F. [Also in Division F2] A spraying device 19 for fluids consists of a pipe 20 with a slot 21 along it and flat flexible metal strips 23 along the edges of the slot extending out from the pipe axis and defining the sides of the nozzle from which the fluid is sprayed. The fluid is supplied at one end of the pipe, the nozzle being at this end wider, with the metal strips parallel, than at the end remote from the fluid inlet, where the strips may touch, the fluid pressure serving here to open the nozzle. This arrangement serves to give a uniform spray over the length of the nozzle. As an alternative both metal strips may be in contact over the length of the nozzle, the fluid pressure parting the strips to open the nozzle. The fluid may also be supplied from both ends of the pipe. As described the sprays are mounted in a treating apparatus, directed at each other as shown, the article to be treated being placed between them, which article 24 may be treated with, e.g., developing fluid, the fluid being recirculated from a trough at the bottom of chamber 10 to the sprays (Fig. 2, not shown). As an alternative the sprays may be mounted above conventional spraying means and spray either a gas or a liquid to prevent the escape upwards of noxious vapour, this being in a treatment vessel similar to that shown (Fig. 7, not shown).
