Title: Filtration
IPC: B30B9/24
Filed: 1970-11-24
Abstract: 1333410 Moving band press filter RUDINVEST AG 24 Nov 1970 [25 Nov 1969] 55717/70 Addition to 1263354 Heading B1D In a press filter wherein material is squeezed. between the opposed, downwardly travelling, converging runs of two endless bands of filter cloth, each band is supported by an articulated belt comprising elements as shown, and each element is made of polyoxymethylene and comprises a flat plate 12 carrying upstanding ribs 2 on one side, whose free edges 4 support the cloth (not shown) and which define therebetween parallel grooves (1) whose rear ends (in the direction of movement) are closed by transverse inclined lip 5, the forward ends of the ribs being similarly inclined at 7. On the other side of plate 12 are formed drainage passages 8, each of which receives liquid squeezed through the cloth and running down the grooves of the next rearward element to be deflected into passage 8 by the lip 5. The lower ends of passages 8 taper at 8b and extend into the wide upper ends of passages 8 in the element below. At the lower end of the filter, cake is scraped from the cloths which are then separated from the articulated belts. Filtrate flowing downwards through the elements of each belt flows out between two adjacent elements where the belt passes round a lower support, after its separation flow the cloth, and into collecting channels. The filtrate is thus prevented from running back on to the cloths.

IPC: C09F9/00
Abstract: 563,271. Heavy metal resinates. JACKSON, L. MELLERSH- (Hercules Powder Co.). April 9, 1942, No. 4681. [Class 1 (iii)] Metallic resinates of modified rosins, having a metal content greater than the equivalent of the acid content of the rosin, are made by heating the modified rosin with a suitable compound of the metal in the required proportions to a temperature of 200-340‹ C. The expression " modified rosin " means a rosin which has been either hydrogenated, or polymerised, or heated at 250-350‹ C. until the optical rotation of the solid rosin has attained a value of + 20 degrees to + 60 degrees. The metallic compound may be a basic compound or a salt of a volatile weak acid, e.g. an acetate, formate, butyrate, or lactate, or an oxide. The preferred metal is zinc, cobalt, or lead. A catalyst, such as calcium acetate, may be employed and the reaction may be conducted in an inert atmosphere. According to a typical example, 82 'parts of a hydrogenated wood rosin saturated to the extent of 63 per cent of both double bonds are heated to 270‹ C. and 53.5 parts of zinc acetate are slowly added while the temperature is raised to 320‹ C. A clear homogeneous resin with a zinc content of 18 per cent is produced. Specification 550,441 is referred to.

Filed: 1969-11-21
Abstract: 1286866 Programmed control of machines; automatic speed control FUJITSU Ltd 21 Nov 1969 [21 Nov 1968] 57222/69 Headings G3N and G3R [Also in Divisions H2 and G4] A servo-mechanism control circuit for supplying stepping motor drive pulses, compensated in dependence on motor, load, comprises a numerical control device 100, Fig.1, containing a pulse-generator developing command pulses which are fed on a line 101 to a pulse train converter 102 which transmits a smoothly varying train of command pulses to an electro-hydraulic pulse motor 107, comprising an electric pulse motor 108, a rotary pilot valve 109 and a hydraulic motor 110. An output shaft 111 of the motor 107 drives a machine tool 112. The command pulses on line 113 count up a counter 118 which is counted down by pulses, from a transducer 119 coupled to shaft 111, to derive the actual error e. The command pulses are also fed through a gate 115 enabled for a certain time by a signal on line 116, to a counter 114, reset through line 117, in which is stored a valve e s proportional to the command pulse frequency and representing the desired system error. The desired error e s is compared with the actual error e in a comparison circuit 120 the output of which controls a gain circuit 124 raising the gain, (defined as the ratio of command pulses to error) by one step when e >e s and lowering the gain by one step when e < e s. The pulse train converter 102 comprises, Fig.3, a register 103 fed with the command pulses on a line 301 to an addition input and the output motor drive pulses on line 316, to a subtraction input. The accumulated error is fed, in binary form, on lines 1 2  0-1 2  n to transistors QO-QN which are rendered non-conductive by a logic "1", that is zero-voltage, on a line so that a current path exists through a corresponding path such as that comprising resistors R30, R40 and diode DO. The resistance value of each path associated with the transistors are weighted in accordance with the corresponding binary valve and determined the pulse frequency of an resistancecapacity oscillator 305 comprising a unijunction transistor Q5. The output of the oscillator is fed, on line 315 to a wave-shaping amplifier 306 comprising transistors Q6, Q7. The gain adjusting circuit 124, Fig.1, is similar to the circuit of Fig.3, except that the transistors corresponding to QO-QN vary the capacitance of the emitter circuit of the unijunction transistor.

Abstract: 1412105 Helicopter rotors WESTLAND AIRCRAFT Ltd 27 Oct 1972 [13 Dec 1971] 57793/71 Heading B7W A helicopter rotor including a rotor hub and a plurality of rotor blades has attachment means securing each blade to the hub comprising two mating cylindrical members, one formed at the blade root end and the other on a radial hub arm, at least two protrusions being located on one of the members engaging in bayonet slots in the other member whereby the blade may be spigoted on the arm and axially rotated to retain it. The blade has a box spar 13 having a wall thickness increasing from tip to root and a flared root end which is bonded to a tapered mandrel 27 and clamped thereon by a split collet 28 retained by a sleeve 29 screwed on to a threaded flange 30 on mandrel 27. An extension of the sleeve 29 constitutes one of said members, the other said member being provided by a housing 20 which is bored to receive the sleeve extension, the bore being formed with two bayonet slots 34 to engage with pins 33 extending radially from the sleeve extension. When the two members are bayoneted together they are locked by a bolt 35 and endwise vibration is reduced by a plate spring 36 positioned between the end face of the bore and a collar 32 secured within the sleeve extension by pins 33. The housing 20 is carried for pitch-changing movements by bearings 21 on a radial hub arm 22 and centrifugal loads are carried by a tie bar 24 attached to arm 22 and housing 20 by bolts 25. In an alternative construction (Fig. 4, not shown) the sleeve extension surrounds the housing, which is formed with bayonet slots on its outer surface. The blade 10 is constructed of glass fibre reinforced plastics material and the spar 13 is wrapped round a foam core (14), (Fig. 3, not shown), with a foam trailing portion (19), a trailing edge member (15), a glass fibre balance weight (16) and a nose cap (38). Torsional stiffness is provided by a cross-ply skin and a leading polyurethane strip provides erosion protection. Balance weights 18 are provided.

Title: Multi-phase alternating current dynamoelectric machine stator winding and method of disposing the winding in slots of the stator
IPC: H02K3/12
Filed: 1966-12-28
Abstract: 1,131,980. Windings for dynamo-electricmachines. GENERAL ELECTRIC CO. 28 Dec., 1966 [28 March, 1966], No. 57909/66. Heading H2A. In polyphase stator windings having concentric pole groups there is a tendency for the end-turns of the outermost coils in adjacent pole groups to touch and to subject the insulation at this point to the full line voltage. This danger is overcome by spacing these adjacent end-turns radially of the core and interposing end-turns of other phases. This is achieved by placing one pole-group 1A of one phase at the bottom of the slots and the other pole-group 6A of that phase at the top of the slots. In addition, the remaining pole-groups 2B, 4B and 3C, 5C extend obliquely from one depth to another so that they lie between the end-turns of the first group. This arrangement is arrived at by first inserting coils 1A in the slot-bottoms, then coils 2B partly overlapping 1A, then coils 3C, 4B, 5C and finally 6A at the slot-tops. The turns may be sinusoidally distributed, i.e. the outer concentric coils may have more turns, and may completely fill a slot. The insulation between coils is augmented by sheet insulating elements 71, 72, 73. These elements (Fig. 3, not shown) consist of legs which extend through the slots between coils, and end portions which lie between end-turns. The coils may be preformed or wound in situ. Overload protection is provided by a temperature-sensitive element 77 having a heat-absorbing fin 78 engaging the windings.
