Patent GB-750200-A (GB)
Title: Improvements relating to ducted-fan, turbo-jet engines
Inventor: RAINBOW HORACE SINCLAIR
IPC: F02C7/14
Filed: 1953-12-30
Abstract: 750,200. Lubricating. ARMSTRONG SIDDELEY MOTORS, Ltd. Nov. 16, 1954 [Dec. 30, 1953], No. 36140/53. Class 12 (3). [Also in Group XXVI] Relates to a turbo-jet engine having a multistage ducted fan 17 driven through reduction gearing and delivering air directly to the compressor 22 and to the jet. According to the invention an intermediate stage of the fan communicates with a surrounding annular passage 35 enlarged at one part to form a collecting chamber 34 having an open side connected to a heat exchanger unit 32 for cooling the oil used in the reduction gearing, means being provided for controlling the air flow through the unit. The oil is drawn from a tank 27 and delivered by a pump 28 to bearing 29. It returns to a collecting chamber 30 and from thence is delivered by a scavenge pump 31 to a header of unit 32. From the header the oil flows over the tubes 40, through which the air passes, to a second header connected to tank 27. The air flow is controllable by a valve 45. The casing 41 of the heat exchanger is stiffened by channel sections members 47.
Patent GB-439595-A (GB)
Title: Improvements in or relating to the spray drying of molasses and other viscous foodstuffs
IPC: B01D1/18
Filed: 1934-12-17
Abstract: A viscous foodstuff such as molasses, honey, milk, cream, eggs, juices, maple or other syrup, banana or other pulp, is dried by spraying the material downwardly into a zone of hot air, which is withdrawn before being fully saturated with water, and then hardened in a lower zone of cool air which is supplied at a pressure to cushion the fall of the dry particles and is withdrawn independently of the hot air.  Preheated, filtered molasses concentrated in a vacuum evaporator 8 is pumped to a steam-jacketed agitating tank 13 from which, at a temperature of 200--238 DEG  F., it is drawn into atomizers 16 by the rotors <PICT:0439595/III/1> <PICT:0439595/III/2> <PICT:0439595/III/3> of pumps 14 which also homogenize the mass and force it through a nozzle 19, Fig. 2, adjacent to an air discharge orifice 24 fed with compressed air from a compressor 26.  A number of such atomizers are arranged above a drying tower 17 each delivering a fan-shaped spray thereto through openings 25 in the tower.  The sprays are herein subjected to corresponding draughts of air issuing through openings 36 in the bottom of shallow ducts 33 to which hot air is supplied by a main 34 communicating with heaters 45 .. 47. The hot air is directed inwardly towards the sprays by angular baffle plates 38 mounted on inclined bars 39.  The hot moist air is withdrawn by an exhauster 51 from the upper part of the drying tower through vibrating screens 32 into a stack 52, the screens preventing escape of dried particles.  The particles are then hardened in a lower zone of the tower which extends into a unit comprising four hoppers 40, cold air being supplied thereto, from a duct 42 connected to a cooling unit 48, through a passage 41 beneath a cruciform baffle 43 which deflects the air downwardly into the hoppers and also through a passage 43<a> between the lower part of the tower and the hoppers so as to facilitate discharge and prevent sticking together of the particles.  The suspension of particles in the cool air is withdrawn from the hoppers by an exhauster 53 to a cyclone separator 54, the powder falling to the base thereof and the air passing to a recirculating pipe 56.  The temperature of the hot air zone is preferably between 365--385 DEG  F.; the cooling zone is below 90 DEG F., and has a relative humidity of less than 40 per cent.

Title: Improvements in and relating to self-discharging receptacles
IPC: B61D7/10
Filed: 1920-12-24
Abstract: 155,837. Krupp Akt.-Ges., F. April 24, 1919, [Convention date]. Hopper wagons.-In a railway hopper-wagon or like receptacle having a bottom C adapted to tilt to either side, springs F are located on each side of the wagon between the bottom C and the underframe A so that as the bottom tilts one spring is put into tension and aids in the return movement of the bottom, while the other spring is rendered inoperative. The springs are connected to the underframe by means of bell-crank levers, one arm E<1> of which is attached to the spring, while the other arm E in the normal position, Fig. 1, of the wagon bottom, presses lightly against a part of the underframe owing to the springs F being both slightly tensioned. The operating-mechanism comprises vertically arranged crank-arms B and links D, and, when the wagon is to be emptied, say, to the left, the left hand crank-arm is rotated inwardly as shown in Fig. 2, thus rendering the left-hand spring F inoperative and placing the right-hand spring in tension.

Title: Improvements in or relating to fluid pressure operated reciprocating motors
Inventor: BUTTERWORTH PHILIP
IPC: F01B17/02
Filed: 1968-09-16
Abstract: 1283525 Hydraulic or pneumatic reciprocating motors BUTTERWORTH HYDRAULIC DEVELOPMENTS Ltd 15 Dec 1969 [16 Sept 1968 18 July 1969] 43931/68 and 36331/69 Headings F1A and F1M The reciprocations of an hydraulically or pneumatically operated reciprocating piston-andcylinder motor la are controlled by a valve 1 comprising a spool 7 slidable in a stepped bore and defining therewith opposed end chambers 12a, 13a and intermediate spool biasing chambers 15, 17, the motor piston 21 co-operating with ports in its cylinder 3 to effect sequential pressure changes in the chambers 12a, 13a, 15, 17 thereby automatically to cause reversal of the valve when the piston 21 reaches an end of stroke position. In the position shown fluid from an inlet 32 is supplied through chamber 13a and a passage 45 to the right hand cylinder chamber 26. The piston 21 thus moves to the left, fluid in the cylinder chamber 25 in front of the piston exhausting to an outlet 47 through a port 60, passage 59 and spool transfer chamber 20. When a land 23 of the piston 21 passes a cylinder port 54, this port is no longer connected to exhaust through an annular transfer chamber 24 and an exhaust port 51, but becomes pressurized from the cylinder chamber 26. Pressurization of the port 54 and a passage 53, 76 connected thereto has no effect since the ends of the passage are closed by the spool 7 and the piston rod 21a. Continued movement of the piston 21 and its land 22 past a port 57 connects the biasing chamber 17 to exhaust via transfer chamber 24, but again this has no effect on the position of the spool 7. Almost at the extreme end of the stroke a recess 27 on the piston rod 21a aligns with ports 72, 75 whereby a passage 71 connected to the spool biasing chamber 14 becomes pressurized from the previously pressurized passage 76, 53. Finally the port 60 conducting the exhaust fluid is obturated by the piston land 22 and fluid is thus trapped in the cylinder chamber 25, thereby to be equalized in pressure by the driving fluid still present in the cylinder chamber 26. Hence pressure in the passage 42 leading to the end chamber 12a rises to a value substantially equal to the pressure of the supply fluid in the passage 45 and end chamber 13a. Accordingly the spool is moved to its opposite end position due to the previously established pressure in the biasing chamber 14. In its opposite end position, passage 42 is connected to the inlet 32 and a passage 62 leading from cylinder chamber 26 is connected to the outlet 47, whereby the piston 21 performs a return stroke in which a similar sequence of events occurs culminating in the reversal of the spool valve. Arrangements for preventing stalling of the piston 21 are described and also an embodiment differing in detail from the preferred embodiment hereabove described.

Abstract: 1,140,136. Mixture of metal soap and metal sulphonate. ESSO RESEARCH & ENG. CO. 17 Aug., 1966 [31 Aug., 1965], No. 36843/66. Heading C2C. [Also in Division C5] A mixture of a metal soap and a metal sulphonate is obtained by reacting an overbased polyvalent metal hydrocarbon sulphonate with from 10-150 wt. per cent of a C 12 -C 22  fatty acid. Suitable fatty acids are lauric, myristic, palmitic, stearic, eicosanoic, oleic, linoleic and hypogaeic and also those obtained from linseed, soybean and tall oil. Preferred polyvalent metals are the alkaline earth metals. The overbased sulphonates contain metal base in excess of that required for simple neutralization of the sulphonic acids to the normal metal sulphonates. The reaction of the fatty acid with the sulphonate is carried out by mixing the two reactants and heating to 100-350 F. The reaction may be carried out in the presence of a mineral oil to give the product as a concentrate. A composition of a hydrocarbon oil and 0À2-5 wt. per cent of the reaction product as a friction modifier is used as an hydraulic fluid in systems employing wet clutches (see Division C5).
