Title: Improvements in or relating to the dewaxing of oil
IPC: C10G73/06
Filed: 1934-11-16
Abstract: In a process of dewaxing oils in a succession of dewaxing stages consisting of chilling and separating the wax, the partially dewaxed oil is heated between each stage to bring the residual wax into solution.  A crude oil is mixed with a diluent such as naphtha, hexane, propane or butane and the mixture chilled slowly to -20 DEG F.  After removal of wax either by centrifuge or by filtration using kieselguhr or similar filter aid, the oil containing fine particles of wax is heated to above 30 DEG  F. and again chilled, preferably to a lower temperature than the first stage, e.g. -30 to -60 DEG  F. to yield a further amount of wax which is separated, leaving a low cold test lubricating oil.

Title: Improvements in and relating to sheet feeding mechanisms
IPC: B65H3/46
Filed: 1934-11-16
Abstract: 426,699. Feeding sheets. FABER & SCHLEICHER AKT.-GES., 8, Sedanstrasse, Offenbach-on-Main, Germany. Nov. 16, 1934, No. 33042. Convention date, Dec. 6, 1933. [Class 100 (i)] To prevent the separation of two sheets at a time by a reciprocating or oscillating suction separator 4 provided with one or more suction apertures 12, 14, an oscillating or reciprocating bar 10 is employed which is made to bear on the separated sheet, thus producing a deflection in the sheet which causes any sheet below the top separated one to fall back on to the pile. The rod 10 may act in conjunction with a sheet pressing- device, and the rod 10 may be caused to move past the apertures 12, 14, or may stop just short of the aperture. The rod may produce a wave of deflection which causes the falling off of any sheet adhering to the top one. The rod 10 may be of circular cross section or of a section similar to a mushroom, Fig. 7, or a crescent, when it is desired to guard against possible folding or creasing of the sheet.

Title: Improvements in progressive change-speed gears
IPC: F16H29/14
Filed: 1920-11-24
Abstract: 154,904. Henriod. C. E. Dec. 2. 1919. [Convention date]. Variable-speed epicyclic gearing controlled by ratchet gearing and a non-rotary adjustable eccentric, as in Specification 8418/09, comprises a skewgear train which works in one direction only. An engine fly-wheel a carries planet gears b, b<111> and a gudgeon a<1> supporting a central gear b<1>. Spur gear b drives a gear c secured to a driven shaft D. The gears b<1>, b<111> are skewed and connected through skew gears b<a>, b<b> on a slanting countershaft G carried by the fly-wheel. The gear b<1> is variably driven through ratchet trains. Spur gears k ratchet mounted on the extended hub d of the gear b<1> are oscillated by toothed sectors l<1>, which are carried by the fly-wheel and are actuated through toothed connexions l designed to obtain uniform movement by levers e<1> having rollers e engaging an eccentric groove in a member f. As the member f is displaced eccentrically, as by hand-operated worm gearing j, the speed of the shaft D is varied downwards from a solid or one-to-one drive. The shaft D may be thus brought to rest and then driven reversely. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a form in which ratchet planetary gears are driven by bell-crank levers carried by a wobbling frame. It also comprises a form with the skew-gear train omitted. This subject-matter does not appear in the Specification as accepted.

Title: Heat exchanger
IPC: F28F27/00
Filed: 1971-07-15
Abstract: 1353940 Reversing valves for heat exchangers KOBE STEEL Ltd 15 July 1971 33303/71 Headings F4P and F4K [Also in Division F2] A heat exchange system comprises a reversible heat exchanger A with a change-over valve C at its hot end and a check valve assembly B at its cold end. Change-over valve C, Fig. 3, comprises chambers M1, M2, M3 with nozzles 48-52, and a valve rod 43 with valve bodies 41, 42, the rod being reciprocable by piston 44 and a further piston 45 at the other end acting as a damping piston. Nozzles 50, 51 are connected to respective gas paths at the hot end of exchanger A, whilst nozzles 48, 49 communicate with a raw air supply. In the position of Fig. 3, waste gas flows from nozzle 50 to nozzle 52 and raw gas from nozzle 49 to nozzle 51, the nozzle 48 being isolated. Movement to the right results in raw air being supplied to nozzle 50 from nozzle 48, with waste gas flowing from nozzle 51 to nozzle 52 and nozzle 49 being isolated. The gas paths are thus reversed. The check valve assembly B, Fig. 4, comprises chambers R1, R2, R3 with nozzles 30-34 and check valve members 14 to 17 hinged to the valve body. From Fig. 6 it can be seen that raw air fed to nozzle 50 flows through to the cold end and enters nozzle 32 in assembly B, the pressure of the raw air maintaining valve member 14 closed but opening member 15 so that air flows out through nozzle 34. Waste gas returns via nozzles 31 and 33 member 17 being opened but member 16 being held closed by the greater pressure in chamber R2. Change-over of valve C leads to automatic change-over of assembly B, raw air then flowing from nozzle 33 to nozzle 34 and waste gas via nozzles 30 and 32. Flow control valves D 1 <SP>1</SP>, D 2 <SP>1</SP>, D 1 <SP>11</SP> control the flow rate in the various gas paths. The assembly B can have its valve members hinged so as to pivot outwardly to open rather than inwardly (Fig. 5, not shown). A single control valve may be used in place of valves D 1 <SP>1</SP> and D 1 <SP>11</SP> (Fig. 7, not shown) and several heat exchange systems such as that described may be used in parallel (Fig. 8, not shown).
