Patent GB-1193295-A (GB)
Title: Fluid Resonator for Use with Sonically Driven Apparatus
Inventor: BODINE ALBERT GEORGE JR
IPC: B06B1/00
Filed: 1967-06-09
Abstract: 1,193,295. Wavecouplings. A. G. BODINE. 9 June, 1967, No. 26816/67. Heading H4J. [Also in Division F2] A coupling for conveying low frequency energy from an orbital mass vibrator to a tool comprises an enclosed volume of fluid and a massive vibratorily movable body coupled thereto which are resonant at the frequency of the generator. The coupling is designed to "tune-out" the reactance of the generator and tool so that effectively the generator feeds a purely resistive load. The tools are low impedance devices such as brushes (Fig. 1) knives (Fig. 2, not shown) or chisels (Fig. 5, not shown) requiring high amplitude, low force vibrations, or abrasive cleaning machines (Fig. 17, not shown) which require low amplitude, high force vibrations. The generator includes a massive roller which is driven to roll around the periphery of a bearing by an electric or hydraulic motor. Such generators are normally rotated at a frequency below their optimum frequency because feedback from the load tends to force the generator to run overspeed. The coupler acts as an isolator in this respect. The coupler considered as a capacitive (fluid) and inductive (mass) network may be connected in parallel or series with the generator and tool. In the "parallel" coupler depicted in Fig. 1, the capacitive portion comprises two liquid filled bellows 6, 7 which are rigidly connected at their remote ends to the tool 4 and generator 3 respectively and at their adjacent ends to a freely movable mass 12 which forms the inductive portion. The volume, pressure or nature of the fluid may be varied to provide optimum tuning. In the "series" coupler of Fig. 3, the bellows are replaced by sealed liquid or pressurized gas-filled cavities 42, 44 which are both directly coupled to the generator 55 via the enclosing cylinder 37 and to opposite ends of a movable piston 41. The latter is directly coupled to a load 59 via stem 49 and it is maintained in an equilibrium position between the two cavities by coiled springs 56, 57. In other embodiments the capacitance is defined by fluid filled chambers which are closed by rubber diaphragms with one or more disc-shaped masses coupled thereto to form the inductance (Fig. 9-13, not shown). As a further alternative the generator 227 (Fig. 15) may be coupled intermediate the diaphragms 212-215 and masses 219, 226, 230, 216, the fluid capacitance chambers being formed at 217, 218, 221, 222.

Filed: 1952-10-27
Abstract: 730,727. Mixing &c. dough. BAKER PERKINS, Ltd. Oct. 27, 1953 [Oct. 27, 1952], No. 26958/52. Class 86. [Also in Group VI] Each pan 2 attached to a traversed endless chain 5, having received a charge of dough either at a filling station D or at an initial station A, where it stops for kneading, then moves to a second kneading station B where the dough during a 4 hours proving is knocked back by further kneading. The pan then returns during further proving to a discharge station C and then proceeds for the next filling at either D or A. Each pan is rotated about its vertical trunnion 10 at the kneading stations as the kneading arm 21 is automatically lowered into the pan for kneading. Each pan is provided with castor wheels or balls 19 running on a closed track. Each pan is hinged to the chain 5 at 16 whereby it is pulled along the track. Each pan is emptied at C where a trap door in the track is lowered automatically to permit the pan to pivot down about its hinge 16 so that the dough is poured out. Fig. 6 shows the pan tipping mechanism in which the trap door 22 is pivoted down about its hinge 23 by rack and pinion 24, 25, the reduction gear 27 containing automatic reversing mechanism to restore the trap door to the level. The pan 2 tips about an angle greater than 90 degrees for good emptying. The chain 5 at this point is retained in a special guide channel 28. An electric motor 8 and reduction gear drives either of the chain wheels 6 or 7 which engages links 18 of the chain. The pan is rotated on its own axis during kneading by direct or bevel pinions 13, 14. Instead of the kneader at A a high speed kneader may be substituted. In this case two ordinary kneaders may be used at B. The kneader at B may be moved on a track parallel to the semi-circular track at 4 so that it is in kneading contact for a longer period as in Fig. 7 or 8 (not shown). At the charging station D there are automatic weighing, measuring and charging means operated automatically by a switch by the arrival of a pan or initiated by the operator, or by a photoelectric device. The track of the pans may enclose a space sufficient to accommodate one or more of the kneaders. Instead of automatic switching of the charging and discharging devices the various motors may be wired to a remote control unit to operate the various devices in timed relation, e.g. by means of a punched card control. The plant may be enclosed in a tunnel to control temperature and humidity.

IPC: C10L3/00
Filed: 1919-11-05
Abstract: 158,633. Brownlee, R. H., and Uhlinger, R. H. Nov. 5, 1919. Hydrogen; carbon.-A gaseous composition for use in welding or cutting metals consists mainly of hydrogen with not less than 2 per cent of a hydrocarbon and not more than 10 per cent of carbon monoxide, the proportions being varied in accordance with the character of the flame required. A process of obtaining a gas of the above composition consists in heating up a bed of refractory material 5 in a chamber 2 by burning fuel and air supplied by pipes 12, 10 in a combustion chamber 9 and passing the hot gases through the material, the gases escaping through a stack 6. When the material is hot, the stack 6 and air conduit 10 are closed and a hydrocarbon such as natural gas, coal gas, oil vapour, or other gaseous or liquid or readily volatilizable solid hydrocarbon is introduced under pressure through pipes 8, and is decomposed to form the desired gaseous mixture. If a higher proportion of hydrocarbon gas is desired, the natural gas or other hydrocarbon used is passed through the refractory material more rapidly than if a lower proportion is desired. If the temperature of the material is increased or the rate of flow retarded a low percentage of hydrocarbon gas will be obtained. The gases pass to a conduit 16 in a water bath 17, a screw conveyer being used to propel precipitated carbon through the conduit into a hopper 21.

Abstract: 1,008,722. Exciting electricity generators. SIEMENS-SCHUCKERTWERKE A.G. July 16, 1962 [July 17, 1961], No. 27304/62. Heading H2A. A self-excited, e.g. three-phase synchronous, generator 1 has for initiating its self-excitation an arrangement including a step-up transformer 5 of which the primary side is initially applied either the remanent magnetization voltage generated by the generator or a voltage derived therefrom and the secondary side is connected through a rectifier system 6 to the generator exciting equipment, the transformer and at least part of the rectifier system being in parallel with the means which supply the excitation voltage during normal operation; the transformer initially assists the means but becomes ineffective to make any substantial contribution to the excitation when the generator voltage reaches a value sufficient for the means alone to effect the excitation. The means comprises a rectifier 4 and possibly a transformer, supplying the exciter winding 2 through a voltage and/or current regulator or control device 3. As shown, the transformer 5 is open-circuited by a relay 7, but in other embodiments its primary voltage is reduced by a temperaturedependent resistance, saturation of the transformer, or a resonant circuit in combination with Zener diodes. The arrangement may include a free-wheeling circuit to avoid overvoltages during switching, and the invention is also applicable to single-phase and D.C. generators.

Title: Improvements in the refining of cotton seed oil
IPC: C11B3/02
Filed: 1932-10-03
Abstract: Cottonseed oil is freed from mucilaginous, resinous, and colour-forming substances by heating with an anhydrous solid boric ester of an aliphatic polyhydric alcohol, and mechanically separating the precipitated impurities.  0.5--5.0 per cent of the esters of glycerine or glycol, treatment at 160--180 DEG  C. under reduced pressure, e.g. 15--50 mm. of mercury, and centrifuging are suitable. The oil may first be partially freed from mucilaginous substances, as by emulsifying with water or dilute solutions of phosphoric acid, sodium chloride, or other electrolytes, and partially bleached by known methods.  It may subsequently be heated with caustic potash or soda; deacidification as by distillation under reduced pressure, preferably with wet or dry steam or mists or vapours of inert liquids, e.g. as described in Specifications 213,267 and 313,254, [both in Class 91, Oils &c.], may follow or accompany the treatment with esters.  For example, 100 lb. of crude cotton oil is mixed with 1 lb. of ester obtained by heating to 150 DEG  C. for 3 hours, 14 parts by weight of anhydrous boric acid with 13 parts of 94 per cent glycerine; the mixture is subjected at 245 DEG  C. and 20 mm. pressure to the deacidification process described in Specification 213,267; after filtration the oil is treated with 5 per cent caustic soda solution and with 3 per cent of a bleaching earth. Specification 341,390 also is referred to.ALSO:Anhydrous esters of boric acid are obtained by heating anhydrous boric acid with commercial glycerine to 150 DEG C. for 3 hours.  The esters may be ground in a ball mill to fine dust. Boric acid esters of other aliphatic polyhydric alcohols, e.g. ethylene glycol, in which the hydroxyl groups are wholly or partly esterified, may be similarly prepared.
