Abstract: 1497313 Unloading silos E H CUMPSTON Jr 28 Oct 1975 [15 Jan 1975] 44353/75 Heading B8S Material 16 such as paper, cardboard, corrugated cardboard and other feltable, non- flowable, generally laminar material is stored in a silo which comprises a base platform 19 and cross beams 15 spaced above the platform 19, the material 16 being supported on the cross beams 15 and due to its properties it forms selfsupporting arches between the beams 15. The latter may be individually lowered into a respective recess 20 in the base platform 19 as shown in Fig. 3, whereby a portion of the material is lowered along with a lowered cross beam 15, the remainder of the material 16 being supported by the other cross beams 15, and the portion of lowered material is then removed from the platform 19 by a vehicle (14), Fig. 5 (not shpwn), which gains access through openings (21) in the silo, Fig. 4 (not shown). The lowered cross beam 15 is then raised back to its original position and the process is repeated with the remaining cross beams 15. Lowering of a cross beam 15 is effected by means of a pair of cranes (13) disposed at either side of the silo, Fig. 4 (not shown). The cross beams 15 may be held in their positions by means of pins (23) which are connected by interlock devices (24) which ensure that only one beam 15 can be lowered at a time. Alternatively two non- adjacent beams 15 may be lowered simultaneously.

Title: Process for the production of lubricating grease
IPC: C08G18/65
Filed: 1965-10-20
Abstract: A lubricating grease is prepared by reacting one or more polyalkylene glycols having molecular weights of 400 to 4000 with 0.2 to 0.8 mole equivalents of a diisocyanate in the presence of 0.5 to 2 moles of water per equivalent of isocyanate group. Suitable components are polyethylene glycols, polypropylene glycols, polybutylene glycols and mixtures of these, particularly a 1:1 mixture of polypropylene glycols of molecular weight 600 and 2000, and 2:4- or 2:6-toluylene diisocyanate or mixtures thereof, or e.g. naphthalene or hexamethylene diisocyanate. Conventional grease additives may be added, e.g. corrosion inhibitors (e.g. phenothiazine), ageing protectives (e.g. phenylnaphthylamine), or dialkylxanthic acid disulphides. The reactants may be mixed at room temperature then heated at 100 DEG  C., preferably being subjected to intense mechanical manipulation in e.g. a kneader, calender or screw.  In examples, toluylene diisocyanate is reacted with a slight molar excess of polypropylene glycol, of uniform or mixed molecular weight, or polypropylene glycol/ethylene glycol mixture and a larger excess of water.ALSO:A lubricating grease is prepared by reacting one or more polyalkylene glycols having molecular weights of 400 to 4000 with 0.2-0.8 moles per mole of polyglycol of a diisocyanate in the presence of 0.5 to 2 moles per isocyanate group (see Division C3).

Title: Improvements in or relating to electrical resistance elements
IPC: H01C17/065
Filed: 1964-11-02
Abstract: A resistance element is constituted by a solidified glass matrix in which is dispersed in finely divided form at least one oxide of a metal from the group consisting of iridium and ruthenium.  Preferably the composition by weight of the element is solidified glass between 96 and 50% and the metal oxide between 4 and 50%.  In manufacture of the element the finely divided oxide of ruthenium or iridium is mixed with finely divided glass and the mixture is mixed with an organic vehicle to form a suspension of suitable viscosity.  The suspension is deposited as a layer on a high-temperature-resistant non-conductive substrate and fired to produce a resistive film, the vehicle being driven off.  The surface of the substrate is preferably lapped and polished and the surface of the fired-on film may be polished.  The substrate may be flat or cylindrical (Figs. 1, 2, not shown).

Title: Unbalance amplifier arrangement suitable for a servo system
IPC: H03F3/387
Filed: 1968-09-20
Abstract: 1,224,758. Amplifier and gating circuits. R.C.A. CORPORATION. 20 Sept., 1968 [25 Sept., 1967], No. 44731/68. Heading H3T. [Also in Divisions G3 and H2] A circuit for amplifying the difference between two input signals applied to two terminals comprises two amplifiers having their input circuits connected to respective terminals and by further connections to both terminals so as to enhance the output from the amplifier giving the greatest output and inhibit the other amplifier. As shown, error signals are applied in opposite senses to differentially connected transistors Q1 and Q2, the output of which control Q4 and Q5. When the signals are equal the voltage applied via the diodes and Q6 to the emitters of Q4 is equal to or more negative than the voltage at their bases so that neither Q4 nor Q5 conducts. If the signal at the base Q1 is larger than that at the base of Q2 the potential at the collector of Q1 falls and at Q2 rises so that the base of Q4 receives a forward bias and Q4 conducts while the base of Q5 becomes severely biased. The rise in voltage at the collector of Q2 is coupled by diode 28 and Q6 to the emitters of Q4 and Q5 so that the forward bias on Q5 also increases. It is thus ensured that both transistors cannot conduct together. The circuit is used to maintain constant the loop on a data tape reel. Displacements of a roller 14 operate a moving core differential transformer type transducer 17 so as to produce an error signal. This is rectified and filtered at 22 to produce corresponding differential D.C. error signals at Q1 and Q2 which are amplified as explained above. Capacitors C8 and C9 charge through 4 resistors R3 and R3<SP>1</SP> and are discharged at the end of each half-cycle of the mains supply by a transistor Q7. When the error is zero the charge is not sufficient to trigger the unijunction transistors Q8 and Q9 but when an error signal is present the current through Q4 or Q5 adds to the charging current to cause the unijunction to fire, the width of the pulses so produced increasing with the error. These pulses fire thyristors in an A.C. bridge to cause an A.C. motor to run forwards or backwards at a speed depending upon the error and so maintain constant tape loop.

Abstract: 1,035,146. Jet propulsion nozzles. ROLLSROYCE Ltd. Nov. 11, 1964, No. 46051/64. Heading F1J. [Also in Division F2] The invention relates to an assembly for example a jet propulsion nozzle adapted for use on a gas turbine engine for supersonic propulsion which comprises an inner cylindrical member about which is concentrically mounted an outer cylindrical member which is spaced from the inner cylindrical member by an annular space. The invention is described with reference to a jet nozzle of a gas turbine engine, the nozzle comprising an inner cylindrical wall 14 of the jet pipe within which is disposed a fixed inner member 20 which is supported by means of struts 22, the downstream end of the jet pipe being disposed in the plane where the diameter of the inner member 20 is a maximum so that the annular space 21 constitutes a convergent nozzle. Around the cylindrical wall 14 and spaced therefrom by an annular space is disposed an outer cylindrical wall 15, the wall 15 being axially movable by means of rams 17 so that when moved downstream from the position shown in Fig. 1, the annular space 21 constitutes a convergent-divergent nozzle. The outer wall 15 is supported on the inner wall 14 by means of a series of rollers 26 (Figs. 2 and 3, not shown) mounted on the pivot pins 25 secured to the inner wall, which rollers engage within channel section members 24 secured within the outer wall 15, the rollers engaging against one wall only of the channel section members whereby the inner and outer members are positively located with respect to each other in the circumferential, horizontal and vertical directions solely by engagement between the rollers and channel-section members. In Fig. 4 (not shown) the wall of the jet pipe is indicated at 14 and the outer wall at 15 the channel-section member secured to the wall 15 being formed by angle members 28. The wall of the jet pipe is formed with cylindrical boss portions 26f to which are secured by clamping means 26d, 26e the inner races 26b of ball bearings, the outer races 26a bearing against one wall 28 of the channel-section member. The inner surface of the inner race 26b is formed with splines which engage with splines formed in the boss member 26f, the splines on the inner race 26b being formed on a cylindrical surface which is eccentric with the cylindrical surface of the outer race 26a. This arrangement permits adjustment of the boss 26f with respect to the channel member. Sealing means are provided to prevent jet gases passing into the space between the jet pipe 14 and the outer wall 15.
