Title: Improvements in or relating to devices for collecting lubricant in refrigerating machines
IPC: F25B31/00
Filed: 1934-10-27
Abstract: 434,515. Regulating compressors. NAAMLOOZE VENNOOTSCHAP MACHINERIEEN-EN APPARATEN FABRIEKEN MEAF, 30, Croeselaan, Utrecht, Holland. Oct. 27, 1934, No. 30891 Convention date, Oct. 31, 1933. [Class 8 (i)] [See also Groups XIII and XXXIV] In a compression refrigerating machine, lubricant separated from the refrigerant in a baffled separator in the conduit between the compressor andthecondenser, or in a liquefied refrigerant reservoir containing a float - actuated expansion valve 13, Fig. 2, is drained back to the compressor suction for a short time while the machine is starting up after an idle period, the drain valve being opened automatically by, a force dependent on conditions in the starting-up period and thereafter closed. The drain valve 5 may be carried by a magnetic ring member 9 pivoted at one point 17 and adapted to be lifted when the current of the driving motor flowing through a coil 10 reaches a high value during the starting period. The device thus acts also to relieve the load on the motor during starting. The Specification as open to inspection under Sect. 91, comprises also an arrangement in which the oil is drained back during idle periods, the drain valve 23, Fig. 3 (Cancelled), at the bottom of a separator 1 being carried by a closed bellows member 20, fixed at one end, in a chamber 24 connected at 6 to the suction of the compressor. During normal working the valve is held closed by the superior pressure within the bellows, and opens when the suction ceases during an idle period. To avoid condensation of refrigerant in the separator by sudden cooling, the admission pipe 3 for mixed vapour and lubricant is formed into a coil with a large number of apertures to ensure quiet flow of gas. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to parboiling, gelatinizing and similarly treating rice, and to apparatus therefor
IPC: A23L7/196
Filed: 1920-11-02
Abstract: 179,206. Simon, Ltd., H., Raeburn, C., and Simpson, A. G. Nov. 2, 1920. Gravity, materials descending by. - A process of parboiling, gelatinizing, or similarly treating rice consists in heating the soaked rice by contact with heated surfaces so that the moisture content of the rice is not increased during heating, and then drying the rice, assisted by a current of air passed through the mass. The soaked rice is fed from a hopper 13 down tubes or other passages or containers 8 of small cross sectional area, which are surrounded by steam, hot air, hot water, flue gases, &c. supplied to the casing 5. The tubes may be flattened at intervals or may be zig-zag or sinuous, or, according to the Provisional Specification. may be inclined. The rice then passes between converging perforated plates 15, the lower end of the passages between the plates being controlled by a slotted plate. 20, reciprocated on rollers 21 by means of a lever 25 and worm-driven cam 28. The cam is so formed as to give a pause at the mid-position shown, and the slot in the lever 25 permits adjustment of the link 24 to vary the travel of the plate 20 and to control the rate of passage of the rice through the apparatus. Air, which may be heated, is supplied to the casing 31, and passes up through the perforated plates 15 into the mass of the rice. The rice leaves the chamber 31 by a pocket wheel 34, forming an air lock, and is received by a ccnveyer 35. The apparatus may operate continuously or the rice may first be parboiled &c. and subsequently dried. Alternatively, two separate devices may be employed in series.

Abstract: 337,933. Wade & Son, Ltd., G., and Wade, G. A. Oct. 14, 1929. Pottery, turning; pottery surfaces, ornamenting. - In apparatus for shaping or decorating earthenware articles or blanks in which the article is fixed non- rotatively and is brought into contact with rotating tools, the tools are carried in radially-adjustable and rotatablymounted slides, thus permitting removal of the debris by centrifugal action. Fig. 1 shows an apparatus for shaping tea-pot lids in which the blanks are held by hand on the top of a spindle c raised and lowered by the continuously-rotating cam d. The downward movement of the spindle is transmitted through links e<1> and bell cranks e" to sliding tools g, thus moving all the latter radially inwards to shape the lid. As the spindle rises again and the tools recede, the blank is removed and a fresh one inserted. The tools are mounted on a frame a which is rotated continuously by the pulley a<1>. A conical spreader h<111> deflects the falling debris from the bearings of the rotating frame towards the exterior where it is thrown off by centrifugal force. Cutters, brushes, bead-runners and colour-sprays are mentioned as tools which can be mounted in the above manner. The tools may be mounted so as to treat the interior of an article instead of the exterior.

IPC: A24C5/39
Filed: 1928-10-27
Abstract: 324,403. Grupe, W. F. Oct. 27, 1928. Tobacco-feeding mechanism.-A tobacco-feeding mechanism for cigarette-making or other machines embodies means for varying the width of the entire stream of tobacco without abstracting from or adding to the contents of the stream. In one form, Figs. 1 and 3, tobacco is fed from a hopper 10 by a carded roller 13, a brushing roller 14, a comb 15, a picker roller 16 and a shoot 17 to a carded conveyer roller 19, on which the tobacco is pressed by a roller 20. The shoot 17 has converging side walls 18 for narrowing the tobacco stream, and converging ribs or corrugations 29. The roller 20 and succeeding conveyer rollers 24, 25 are progressively narrower, shoots 23, 29 and picker rollers 22, being provided between successive conveyer rollers, and the tobacco from the roller 25 passing into a shoot 26 leading to a cigarette-rod mechanism. The surface speed of successive conveyer rollers may differ, for instance the speed increasing as the rollers narrow. In a modification, Fig. 12, tobacco is removed from a conveyer roller 19 by a picker roller 22 and is guided by a plate 32 and a shoot 23 with converging side walls 18 and ribs 29 to a narrower conveyer roller 24. Below the shoot 23 may be provided a tobacco-projecting device consisting of a roller 44 having vanes 45 curved as shown in Fig. 20 to cause the tobacco stream to converge. In another form, Fig. 10, tobacco removed from the roller 13 by the picker roller 16 is directed by guide plates 32, 33 to a projecting roller 34 having vanes with radial faces 35 and stream-lined following faces, the vanes being curved to cause the convergence, of the tobacco stream directed on to the narrower conveyer roller 37. The projector 34 may be replaced by a device shown in plan in Fig. 15 and comprising a curved director plate 46, with converging side walls 18, extending from a compressed-air pipe 47 having orifices or slit for projecting the air over the surface of the plate. The plate may be ribbed, or the pipe 47 provided with converging nozzles 50, to ensure convergence of the tobacco stream. In a further form, a projector 34 such as shown in Fig. 10 directs the tobacco on to a succession of such projectors, each having curved vanes for first widening and then narrowing the tobacco stream, and being driven at speeds varying with the variation in width of the stream. The last projector, which directs the tobacco into the shoot of a cigarette-rod mechanism, may have straight vanes. Specification 322,803 is referred to in the Complete Specification and 325,864 in the Provisional Specifications.

Abstract: 1446872 Carbon fibre sheet KUREHA KAGAKU KOGYO KK and TOYO BOSEKI KK 2 July 1973 [3 July 1972] 31340/73 Heading C1A [Also in Divisions D2 and H1] A carbon fibre sheet suitable for use as an electrode in a fuel cell is prepared by forming a carbon fibre mat by a paper making step using a furnish comprising carbon fibres and a binder therefor, impregnating the mat with a solution of a carbonizable resin, heating the mat to carbonize the resin in order to produce a mat in which the fibres are bonded by amorphous carbon, and heating the carbonized mat in the presence of a gaseous organic compound to deposit graphite or carbon on to the mat by thernal decomposition of the compound. The carbon fibres may be of amorphous carbon or graphite, or both, and preferably have a length of 1 to 10 mm. and a diameter of about 10 Á. The binder may be polyvinyl alcohol. The carbon fibres may have a random or a particular orientation. The carbonizable resin may be a phenolic resin, and may be carbonized at about 1000‹ C. The thermal decomposition step may take place at 600-2400‹ C., and suitable organic compounds include methane, ethane, propane, town gas, polycyclic compounds and derivatives thereof, and fractions from coal or coal tar. Up to 5% of inert gas may be present in the atmosphere in the thermal decomposition step. The resulting sheet may be further heated to convert amorphous carbon into graphite. The sheet may have a thickness of 0À2 to 5 mm., a porosity of 50 to 70%, and an electrical resistance of 0À05 # cm. In the example, a carbon fibre mat is produced on a paper making machine from a suspension of 3 mm. carbon fibres in an aqueous solution containing a dispersing agent and 10% by weight of polyvinyl alcohol resin. The mat is treated with 0À5% by weight of phenol solution of phenolic resin in methanol, maintained at 180‹ C. for 1 hour to set the resin, and heated at 1000‹ C. for 3 hours to carbonize the resin. The resulting mat was treated in the following thermal decomposition step at 1300‹ C. The physical properties of the carbonized mat and the final sheet are described.

Title: Improvements in or relating to gearing for steering mechanically propelled vehicles and for other purposes
IPC: B62D3/04
Filed: 1938-10-29
Abstract: 520,359. Cam mechanism. BISHOP, R., and JOHNSTON, R. H. Oct. 29, 1938. No. 31369. [Class 80 (iii)] In gearing wherein a cam 1 is engaged by a follower 2 on a rocker arm 4 actuating a shaft 5, the centre line 11 of the rocker arm when the gear is in mid-position, is inclined to a plane normal to the axis of the worm at an angle equal or substantially equal to the pitch angle of the thread of the worm at the point of contact of the cam and follower. Thus, in the usual gears of this type, the axis of the rocker shaft 5 is at 12, whereas in a gear according to the invention it is at 13. This results in equal efforts being required to move the rocker arm through equal angles on opposite sides of the mid-position. Further, there is less variation in the thickness of the threads of the worm and excessive wear at the end x of the worm is obviated. The gearing is applicable to the steering of vehicles and to the actuation of the throttle or ignition timing of internal-combustion engines. Specification 223,963. [CLass 80 (iii)], is referred to.

Title: Improvements in and relating to game apparatus
IPC: A63F9/14
Filed: 1927-11-23
Abstract: 311,828. Graham, J. E. Nov. 23, 1927. Race games, mechanical.-In a game apparatus with bodies progressed over fixed obstacles, the bodies have one or more pendant projections which engage between the turns of a rotating helical wire thread or spring, the spring being a tension or compression spring. The bodies usually have two projections, but more may be provided to give a varied action, the pitch of the helix agreeing with the spacing of the projections. The projections take through a slot in the track, and the slot may be out of centre with the helix. The housing of the helix may have a curved base to permit the helix to move laterally and roll axially. The housings may be straight or curved, and each helix arranged to rotate on its own axis, but with curved tracks the disc carrying the coils may rotate on its centre. For race games, two or more tracks are arranged side by side, or concentrically. The helix may be rotated by a spring, weight, or electric motor. In the form shown, a handoperated fly-wheel 12, Fig. 2, having a leather disc 15 engages a roughened or toothed wheel 28 mounted in a rocking frame 19. This frame carries axles 23 secured to the springs 25 and having wheels 22 geared to a wheel on the axle of wheel 28. Alternate helices are then made of opposite hand excent when the bodies start from opposite ends. The wheels 12, 28 are held in engagement by a spring 27 engaging the frame 19 which can be rocked by a lever 26 to disengage the gearing. The wheel 28 may be replaced by twin wheels 52, 53, Fig. 10, roughened on half their peripheries to give varying movement to the helices. The track is provided with obstacles 32, Fig. 2, to represent ditches or water jumps, and these may be slotted only in their upper portions. The tracks may have pin-head projections or serrations in places, or depressions 33 may be formed. The first body home engages a flap 34 which falls on to teeth 39 on a pivoted bar 37, the second body home pushing its flap on to a second row of teeth 40. A third row of teeth may also be provided. The flaps are reset by a bar 51 with a handle. The figures 41, Fig. 5, have a front projection 46 with a cam surface so that the helix lifts the figure, while the rear projection 47 is hook-shape so that it remains in engagement with the helix for a period until the weight of the figure rocks it forward again. The projections may have a stepped profile to vary the action. The base of the figure has a curved front 43 for riding over obstacles, and may have a curved centre 44, the centre of gravity of the figure being in advance of the curve 44. The centre of gravity may be made variable by constructing the figure in two parts, or by inserting a ball or other object inside the figure. The figures may represent jockeys or knights on horses.

Abstract: 1,262,968. Gas turbine plant. R, FERRARI. June 24, 1969 [July 4, 1968], No.31733/69. Heading F1G. The invention relates to a gas turbine engine suitable for driving road vehicles, the engine comprising a compressor 1, air pre-heater 16, combustion equipment 15, a first stage turbine 2 and a second stage turbine 3, the turbines, compressor and output gear 13 being inter-connected through planetary gear sets 4, 5, the output gear being connected through differential gear 14 to the drive-shafts of a vehicle. The first turbine 2 is connected to a sun gear 8 which is connected through planetary gears mounted on carrier 9 to a ring gear 7 which is connected to the compressor 1. The second stage turbine 3 is connected to a sun gear 12 which is connected through planetary gears mounted on carrier 11 to a ring gear 10 which is integral with the planet carrier 9. The planet carrier 11 is integral with the output gear 13. In operation for example with increasing load the speed of the gear 13 is falling and so the speed of the ring gear 7 and thus the speed of the compressor is increasing, resulting in increased air supply to the combustion equipment and so of working fluid to the turbines. Thus the speed of the output gear tends to be restored to its original value.
