Title: Improvements in Devices for Clamping Wood and the Like
IPC: B27B29/08
Filed: 1968-02-19
Abstract: 1,193,914. Sawing. ETABS. GUILLIET. 19 Feb., 1968 [21 Feb., 1967], No. 7959/68. Heading B5L. [Also in Division F2] A device for clamping a log on a log-saw carriage comprises two transmission systems in parallel and having different ratios, the high speed system being preponderant, and a friction coupling coaxial with the screw of the device and controlled by the reaction of the latter to make the low speed system preponderant during the active phase of clamping or unclamping. The carriage has an upright 1 formed with a vertical rectangular guideway for supports 12, 13 having opposing grips 14, 15. A screw 2 is rotatably mounted in the lower support and engages a nut 16 fixed to the upper support. The upper end of the screw is keyed for axial movement in a sleeve 5 rotatable in the carriage 1. A plate 6 is keyed to the sleeve and carries a pulley 21 which is connected to the plate by tangentially disposed springs 28 extending between pins 42 on the pulley and a lug 41 on the plate. A gear 7 is rotatable relative to the plate but can be locked thereto by friction rollers 33 engaging wedge-shaped recesses 34 in the plate. The gear 7 engages an intermediate gear 30 on a shaft 40 having a further gear 29 meshing with a gear 4 keyed to the shaft 9 of an electric motor 3. The pulley 21 is joined by a belt 22 to a pulley 20 held between friction pads 24 on the motor shaft 9. In operation, with a log in position on the carriage, the motor 3 is actuated and, with the springs 28 maintaining the projection 41, and hence the rollers 33 in a mid position so that there is no drive between the plate 6 and gear 7, the belt 22 rotates the screw at the high speed to lower the upper clamp into engagement with the log. The nut 16 is thus fixed and the screw moves upwardly so that the lower clamp engages the log. As the clamps exert force in the log, the load on the screw moves the plate 6 relative to the pulley against the force of the springs 28 until the rollers 33 frictionally engage the recesses 34 on gear 7 and the screw is rotated at the lower speed by the gearing 7, 30, 29 and 4 from the motor shaft 9, the pulley 20 turning against the pressure of the friction pads 24. In other embodiments, the device is of the type having a collar for the pieces of wood and the like or of the centring type in which the screw has two portions threaded in opposite directions, each position carrying a nut provided with a centring plate.

Filed: 1965-02-25
Abstract: 1,096,224. Counterbalancing apparatus; liquid cargoes discharging. FMC CORPORATION. Feb. 25, 1965 [March 2, 1964], No. 8067/65. Headings B8B and B8E. A fluid transferring apparatus comprises an inner boom 30 pivoted at 26 intermediate its ends, an outer boom 45 pivoted at 38 to the outer end of the inner boom, and a counterweight 104 located at the inner end of the inner boom and coupled to the outer boom in such a way that it counteracts the turning moment of the outer and inner booms about the pivot axis 26 and the turning moment of the outer boom about the pivot axis 38. The counterweight 104 is pivotally mounted by arms 100 which are adjustably mounted on members radially extending from and secured to an inner sheave 80. The latter is journaled in the inner end of the inner boom 30 and is coupled by an adjustable tension cable 82 to an outer sheave 50 secured to the inner end of the outer boom for rotation therewith about the axis 38. Therefore, rotation of the outer boom 45 relative to the inner boom 30 causes rotation of the inner sheave 80 displacing the counterweight 104 to counterbalance the boom 45 about axis 38, the two booms being counterbalanced as one about axis 26 by displacement of the weight 104 due to displacement of the inner end of the inner boom. The booms are of tubular construction, through which fluid is transferred from a riser 19 to a tank coupling 61, elbows and swivel joints being provided at the ends of the booms. The inner boom 30 is horizontally offset from the riser 19 allowing the inner sheave and counterweight to pass thereby as the booms are rotated about the horizontal axis 26 from one side of the riser to the other.

Title: Improvements in or relating to protective systems for electric conductors
IPC: H02H1/00
Filed: 1922-03-22
Abstract: 200,876. Reyrolle & Co., Ltd., A., and Biles, R. W. March 22, 1922. Protective arrangements of the Merz-Price type for feeders, generators and transformers employ a divertor relav or contactor connected across the current transformers in the ends or sides so that, on the passage of a straight-through current above a certain value, the sensitiveness of the trip coil of the main circuit-breaker or of the relay which trips it is decreased but at other times the sensitiveness remains unimpaired. By these means the usual want of balance of the balancing transformers is compensated for. As shown in Fig. 1, applied to a single feeder, the balancing transformers D connected to the relays coils C in the usual way through pilot wires E are short-circuited by the coils F of divertor relays. With heavy straight-through currents the divertor relays are closed thereby connecting a shunt resistance G across the relay coils C and reducing their sensitiveness. The arrangement for a three phase feeder is similar, but where the feeder section is connected to an adjacent section through a power transformer the divertor relay acting in conjunction with the operating relay of one phase conductor is energized from the current transformer of another phase conductor. The invention is shown in Fig. 5 applied to a fan conductor system in which one phase is split into two parallel conductors A<5>, A<6> which are connected to the opposed primaries of transformers J at each end the secondaries of these transformers energizing relays C<2> which control the tripping circuits. Two balancing transformers J<1> are employed each having four windings opposing one another in pairs. According to the invention as applied to this arrangement each of the coils C<2> is shunted by a resistance G<2> introduced by a divertor relay F<2> energized by a secondary winding on the adjacent transformer J<1>.

Abstract: 1,057,891. Spray carburetters. HYSTER CO. Feb. 28, 1964 [March 12, 1963], No. 8390/64. In a carburetter for a load-lift vehicle with a suction pick-up device, where the carburetter operates with abnormally low intake pressures when a load is being lifted, the fuel supply is reduced when operating under the low intake pressure conditions by a control valve 22 which opens to admit air through pipe 13 to the part of the fuel well 11 adjacent the fuel orifice 12. The valve 22, which is seated at 24 under normal operating conditions, is actuated by a diaphragm 21 subject to intake pressure through pipe 18, the carburetter intake 8 being connected to a filter which can be connected either to atmosphere through valve 41 or, when valve 41 is closed, to the suction pick-up device 40. Under normal operating conditions air enters the float chamber 16, connected to the carburetter intake by pipe 9, freely through passage 28, seat 30 and passage 16 but under abnormally low intake pressure conditions valve 22 is lifted to close seat 30, whereby the flow of air to chamber 16 is metered by orifices 26, 29, to maintain a pressure in chamber 16 which is below atmospheric but always above the boiling point pressure of the fuel. The carburetter idling passage 62, Fig. 3 (not shown) has an opening 65 to the fluid chamber whereby the idling fuel is cut off at low intake pressures.

Title: Preparation of molybdenum dioxide
IPC: C01G39/02
Filed: 1964-02-28
Abstract: MoO2, having a content of S not more than 0.1% by wt. and not more than 10% by weight MoO3, is obtained by heating a substantially stoichiometric mixture of finely divided MoO3 and MoS2 at 600-700 DEG C. under normal pressure and free release of SO2.  When the SO2 release becomes very small, the product is disulphurized by keeping it under normal pressure in an atmosphere containing < 10% SO2 at > 400 DEG  C. and finally cooled to 250 DEG  C. in a non-oxidizing atmosphere (e.g. nitrogen).  The several stages of the reaction may be performed within the same space, two separate spaces or in two separate compartments of the same furnace. The desulphurization stage may be carried out in a current of inert gas or, if a relatively high content of MoO3 can be tolerated, in a slightly oxidizing atmosphere. In the former case, the same inert atmosphere may be used for the cooling stage.

Abstract: 558,670. Rectifying vapours; distilling ammonia liquor. HOLMES & CO., Ltd., W. C., COOPER, C., and HENSHAW, D. M. June 22, 1942, No. 8510. [Class 32] In maintaining a constant temperature in a condenser or deflegmator, employed in the rectification of vapours, by indirect contact of the vapours with a boiling liquid, adjustment of the boiling point of the liquid to the required temperature is obtained by employing a mixture of liquids which do not form an azeotrope and altering the composition of the mixture by fractionating it and removing one of the components or by increasing the proportion of one of the components. The process is applied to the concentration of ammonia liquor and a primary distillate from the ammonia still comprising 20pts. ammonia, 15pts. carbon dioxide and hydrogen sulphide and 65pts. steam is obtained by passing the vapours through a fractionator maintained at 91‹C.; also to the recovery of crude benzole in which deflegmator is maintained at 87‹C. Mixtures of hydrocarbons are preferred, e.g. benzene and toluene. Vapours from a still are passed through a deflegmator 1 entering at 3 and leaving at 4 the deflegmator being provided with tubes 2 through which a' boiling mixture is circulated from a condenser 6. Ajustment of the temperature is obtained by insertion in the circuit of a separator 11 from which a fraction is withdrawn through line 10 thus altering the proportion of the constituents of the mixture and reducing its boiling point.
