Title: Control means for effecting the sequential operation of adjoining conveyers
IPC: B65G23/00
Filed: 1945-04-11
Abstract: 592,868. Conveyers. SMITH, H. W., and OXLEY, A. April 11, 1945, No. 9039. [Class 78(i)] [Also in Group XXXVII] Control means for effecting sequential operation of two adjoining conveyers comprise a rotatable unit interposed between the two conveyers, said rotatable unit being automatically operable by a rotatable member of the preceding conveyer, and a plunger for actuating the press button of the motor starter of the second conveyer which is operable with delayed action by the rotatable unit. In Fig. 1, spindle 10 of the driven roller of one conveyer causes press button 36 of contact maker 35 of the next conveyer to be depressed by rotating screw pump .13 (through coupling 11) which drives oil from reservoir 23 via passage 28 to the rear of plunger 25, so moving stud 37 into contact with button 36. Valve 33 controls rate of flow of oil and thus -regulates interval of time before contact is made. 38, 39 are filler and drainer caps respectively. In Fig. 3, linkage 55, 57 is fixed by pins 58 to hollow spindle 41, and to sliding inner shaft 44 by pins 54 sliding in slots 53 in hollow . spindle and carry movable weights 56 at their junctions. Rotation of driven roller 40 of one conveyer causes depression by knob 68 of press button starter 67 of second conveyer through the outward centrifugal movement of weights 56 which displaces pins 54, and shaft 44 attached thereto, to the right: this displaces static coupling member 45 and, in consequence, plunger 49a and knob 68 which are connected thereto. Valve 63 controls the rate of movement of oil to reservoir 59 and therefore the time lag in actuating the starter of the second conveyer.

Title: Improvements in or relating to moulding mixtures
IPC: C08L61/10
Filed: 1929-03-20
Abstract: 330,968. Wade, H., (Bakelite Corporation). March 20, 1929. Phenol-aldehyde condensation products. - A process for preparing a moulding mixture comprises mixing a high-boiling aldehyde with a filler and then adding a potentially reactive phenolic resin, or mixing a methylene-containing compound and a high-boiling aldehyde with a filler and then adding a non-reactive phenolic resin. Examples of aldehydes are benzaldehyde, hexyl aldehyde, isohexyl aldehyde, mannoheptose, methylfurfural, nitrobenzaldehyde, phenylacetaldehyde, and tetrahydrobenzaldehyde; a suitable methylene-containing substance is hexamethylenetetramine. The aldehyde acts as solvent, plasticizer and hardening agent. In an example wood flour is kneaded with about 10 per cent of its weight of furfural, and with hexamethylenetetramine; an amount equal to the weight of the wood flour and furfural of a permanently fusible resin prepared by reacting 7.5 mols. of phenol with 6 mols. of formaldehyde is slowly added and kneading continued at approximately 100‹ C., and the mixture is then cooled and ground. Specifications 225,436, [Class 87 (ii), Moulding plastic &c. substances], and 230,619 are referred to.

Abstract: 945,541. Magnetic testing apparatus. ELLIOTT BROS. (LONDON) Ltd. March 9,1960 [March 16, 1959], No. 9088/59. Heading G1N. In a proton precession magnetometer wherein measuring equipment connected to the proton precession signal detecting means is arranged to measure the periods of time occupied by selected numbers of cycles of the detected signal, the number of cycles is so selected that the periods of time to be measured will always approach a substantially constant value. The output from winding 2 of the magnetometer head 3, when power from D.C. supply 4 is suddenly removed, is applied via a band-pass filter 6 and a shaping amplifier 8 to a sequence of counters 9,10,11, the first output from counter 10 opening a gate 15 to pass the output from a 200kc/s crystal oscillator 16 to a sequence of counters 15-21. The count of these pulses is terminated by the first output pulse from counter 11, and the ten thousand digit on indicator 24 is applied to control a servomotor 27 whereby the gauged band-pass filter, and counter, selector switches 7,12-14 are adjusted if the count in 24, i.e. the period of time for which the precession pulses is counted is too high or too low. The counter selectors preset the number of input pulses to produce an output pulse, and typical count switch position figures are given. The measurement and reset is controlled by an automatic programming device 5, and the selector switch settings are recorded together with the timing pulse count. The system enables aerial photography to be synchronized with the readings.

Patent GB-702986-A (GB)
Title: Improvements in or relating to apparatus for and a method of separating oil from aqueous liquids
IPC: C11B3/00
Filed: 1950-04-17
Abstract: Oils (i.e. vegetable or mineral oils, fats or grease) are separated from aqueous liquids by introducing the mixture in a state of swirl directly into a high potential electric field formed within a vessel between superimposed spaced electrodes disposed in the lower part of the vessel, withdrawing the separated oil from the vessel above the electric field and withdrawing the aqueous liquid and sludge from the vessel beneath the field.  The process may be applied to the separation of crude mineral oil from brine or to the separation of oil from effluents which normally pass to waterways or drainage, particularly on ships.  The mixture may be heated prior to or during dehydration, while the aqueous liquid withdrawn may be filtered or centrifuged before discharge.  In the case of D.C. supply or a single phase alternating supply, two electrodes may be employed but in the case of a 3-phase supply, three electrodes may be employed; a potential drop of 1,000-10,000 volts is suggested.  In the Figure, a mixture of oil and brine is fed into column 10 through pipe 18 which ends in rotatable distributing cap 20.  The mixture is thus introduced into column 10 between electrodes 22 and 23, 22 being earthed and 23 being vertically adjustable.  Separated oil is withdrawn through conduit 33, provided with a float-controlled valve, while separated brine is withdrawn through conduit 37 and a <PICT:0702986/III/1> discharge valve 13 is provided for sludge. Brine from conduit 37 may pass to a centrifugal separator to remove the last traces of oil.  Baffles may be mounted one above the other on the rod 24 above the electrode 23.  Furthermore, when electric power is not available, the apparatus may operate on a gravitational principle only, as described in Specification 238,750, [Class 46]. For this purpose the bracket 26 which carries the guide for the rod 24 may be arranged to be readily removed from the column, and an asemblage such as that described in Specification 238,750 may be inserted in its place.  Also, as indicated in Specification 238,750, additional inlets and a distributer may be provided at the top of the column.  Column 10 may also be equipped with two mixture inlets for use in the electrical dehydration of oils, the additional inlet being furnished near the top of the column, but below the float gear; the extra inlet is used in cases where the oil is in excess of the heavier aqueous liquid in the mixture. According to the Provisional Specification, in the case of a 3-phase electric supply, three electrodes may be provided in the form of plates extending in an up-and-down direction and spaced apart around a circumference.

A rotary pump (which may be adapted as a motor) comprises a stator formed of a tube 2 of rubber or other flexible material inside a tube 1 of rubber or the like, the two tubes being bonded together as at 4 to create a number of passages 3. The outer tube 1 may be bonded to a rigid barrel 7, the ends of the tube being clamped between the barrel and the end cover assemblies 8 and 9. The end cover assemblies form, in conjunction with the bearing housings 14 and 15, the annular chambers 10 and 11 which connect with the inlet and outlet ports and also serve to clamp the inner tube between the faces 18, 19, 20 and 21. A cylindrical rotor 22 having a helical groove or grooves 23 cut in its surface rotates within the tube 2 causing fluid in the passages 3 to be forced along from one end of the pump to the other. The rubbing surfaces should be lubricated by glycerine or other suitable lubricant admitted through the ports 25 and 26. The part 2 may act as the stator and the casing be rotated. The rotor may be formed by twisting stout wire into a single or multi-start helix. The flexible tubes or passages may be formed from plastic material, sheet metal or woven fabric.

A modular electrical circuit assembly comprises a row of insulating boxes each containing electrical components connected to regularly spaced electrical contacts on opposite sides of the box, and a row of connector blocks mounted on a base plate and receiving between each pair of blocks at least one of the boxes, each block having a series of regularly spaced electrical contacts engaging and electrically connecting together contacts of one box with those of an adjacent one. As shown in Fig. 1 electrical components, e.g. of a transistorized radio receiver, are inserted and potted in a series of hollow insulating boxes 20 which are inserted between connector blocks 18 on a metal base plate 12. Leads 24 of the components are electrically connected to contact elements 26 each consisting of a connecting socket, Figs. 2, 3 (not shown) having a channel-shaped U-crosssection body portion the upstanding side walls of which provide the exterior contact surfaces of the units. The contacts are held in position in channels 30 in the hollow boxes by lugs which extend transversely of the channels 30 and engage behind shoulders extending transversely of the channels and provided by a V- cross-section groove 36 in the bottom of the box 20. The connecting blocks 18, Fig. 4 and Fig. 5 (not shown), include a row of generally flat blades 28 which are disposed parallel to and in alignment with one another in slots 44 provided with bores 50 in nylon supports 42 of T-cross-section, each bore 50 co-operating with a longitudinally extending rib 52 on a blade 28 to guide and align the latter. The width of each blade 28 is twice that of the central portion 46 of the nylon support so that the side edges 39, 40 of the blades protrude from opposite sides of the portion 46 for engagement with the contact elements 26. Each blade 28 is inserted through the base 48 into the corresponding slot 44 and held in position by tabs 58, 60. The blocks themselves are moulded integrally with pairs of rails 62 which extend longitudinally of each block 18 and are laterally spaced from one another to fit snugly within a slot 64 in the plate 12. The rails are held in position by a U-shaped spring fastener 66 having legs 68 arranged to run in grooves 70 in the outer lateral faces of the rails and overlap the lower face of base plate 12 over about half its width. An auxiliary electrical connecting element is provided by a tab 72 integral with the blade 28 and provides access to each junction formed by a blade 28 and contact element 26 for connecting a tuning device or loud-speaker to the modular circuit, or for the connection of feedback lines interconnecting the units 2. The arrangement is particularly suitable for circuits comprising a number of series-connected stages each of which can be housed in one of the units 2. Specification 927,481 is referred to.
