Title: Improvements in or relating to Variable Resistance Control Units.
IPC: H01C10/14
Filed: 1967-04-19
Abstract: 1,187,823. Adjusting devices. CTS CORP. 19 April, 1967 [20 April, 1966], No. 18042/67. Heading H3Q. [Also in Divisions F2 and H1] A variable resistance unit has a slipping coupling for preventing relative movement of the two parts beyond a predetermined point, the coupling comprising a driven member having a rim part of which can flex to interrupt the connection between the driving and driven members. Fig. 3 is an exploded view of a variable resistance unit containing a resistance track 44, sliding member 60 and gear-wheel 20. The latter is driven by a worm-wheel 31 (Fig. 5) formed integrally with a screw head 34 which projects out of the back of the unit (Fig. 1, not shown); the worm is prevented from moving axially by a groove 33 into which projects a nylon pin 32 (Fig. 3) sufficiently tightly to secure the worm against vibration or shock. The gear-wheel 20 is preferably of insulating material such as nylon or polyfluorodichloroethylene; if of metal, the worm should be of insulating material. Rotation of the gear-wheel is communicated to the resistance slider 60 by means of pins 28 which are a force-fit in a hole 62 and opening 61 in the slider. The lower side of the gear 20 has an annular portion (26 in Fig. 4, not shown) of reduced thickness separating the hub of the wheel from the rim. This annular portion is interrupted by a short section (27) of the full thickness of the gear, and when the gear has rotated sufficiently for the slider 60 to reach the end of the resistance track this section (27) abuts against a projection 18. On the other side of the gear the reduction in thickness is carried through to form an arcuate slot 29. If the worm continues to rotate after the section (27) has reached the stop 18, the rim of the gear adjacent the slot 29 will flex inwardly and disengage the teeth from the worm, preventing damage to the resistance unit. It may not be necessary for the slot 29 to extend through the full thickness of the gear. In an alternative form (Fig. 6, not shown) the slot 29 is divided into two parts each of which reach the edge of the gear so that a portion of the toothed rim forms a separate segment. The gaps are small enough to permit continuous engagement of the gear with the worm. Resistance track (Fig. 3).-This comprises a ceramic film 44 fired on to an alumina or steatite substrate 42 as in Specification 1,091,916, or alternatively a carbon track or wire-wound element. Contactor 64a wipes the track while contactor 65 rotates on a centre collector 45. L-shaped leads 49 enter holes 47 in conductive pads 51 at the ends of the track and are fastened thereto by a conductive epoxy resin. A lead 50 is similarly attached to the centre collector at 48. The leads are fastened to the substrate by an insulating epoxy resin (53 in Fig. 1, not shown). The whole unit is enclosed in a housing 11 of diallyl phthalate resin or die-cast aluminium. The substrate 44 rests on a ledge (12b in Fig. 2, not shown) and the annular gap round the edge of the substrate is filled with adhesive (56).

Abstract: 221,052. Trumble, M. J. July 12, 1923. Hydrocarbons, cracking. - In distilling heavy oil mixed with coal to obtain gasoline &c. the materials are heated under pressure in a closed retort by means of superheated steam at about 800‹ C. The steam and vapours are, before condensation, passed through a turbine or other prime mover and used to generate electricity. The treatment is carried out in a series of retorts 1, each of which is connected to a main 7 for supplying superheated steam from boilers 13 and superheaters 15, a main 8 for supplying heavy oil mixed with powdered coal, a vapour-collecting main 9, from which the steam and vapours are passed through a turbine 28 and thence through dephlegmators 33, 34 and by a pipe 41 to a condenser. A heavy oil mav be supplied to the top of the dephlegmator 34 by a pipe 43, and this oil together with condensates is mixed with powdered coal fed into the base of the dephlegmator 33 by a worm 47 from a hopper 46. The mixture is forced into the main 8 by a pump 23. The retorts are connected so that vapours generated in one retort mav be passed into the. next retort of the series. In operation, lignite contained in one of the retorts is dehydrated, by filling the retort with heated heavy oil from a main 11 supplied from a tank 56 through a pump 67 and heater 63. Excess of oil flows from the top of the retort to a main 12 and is returned by a pipe 59 to the tank 56. Steam escapes through a pipe 80. When the lignite is dried, the oil is drained to a main 10 and back to the tank 56. Steam and vapours from another retort of the series are passed into the top of the retort, the mixture of steam and vapour pass to the main 9 and thence to the turbine 28. Superheated steam from the main 7 and a mixture of heavy oil and powdered coal from the main 8 are then passed into the retort and the mixed vapours from the retort are passed through a second retort before entering the main 9.

Title: Manufacture of cation exchangers
IPC: B01J39/18
Filed: 1937-07-01
Abstract: Artificial resins insoluble in water and having cation exchange properties are prepared by introducing w-sulphonic acid groups into a water-insoluble resinous condensation product from a phenol and formaldehyde, without appreciably reducing its insolubility in water, by the action before, during or after the condensation, of formaldehyde and an aqueous solution containing a sulphite or a bisulphite in such amounts as to provide not more than 0,7 mol. of SO311 for each mol. of phenol.  In the cases where the amounts of SO311 approaches 0,7 mol. for each mol. of phenol, the w-sulphonated resin is after-treated with acid, e.g. hydrochloric acid, to produce sufficient insolubility in water.  In the examples, resins formed by the condensation of m-cresol and phenol respectively with formaldehyde are treated in this manner.

Title: Improvements in or relating to Telephone Systems.
IPC: H04Q1/32
Filed: 1917-12-13
Abstract: 112,026. Automatic Telephone Manufacturing Co., (Assignees of Martin, T. G.). Dec. 15, 1916, [Convention date]. Automatic exchange systems.-In order to prevent accidental movements of the hook-switch, caused by careless removal of the receiver, from producing a false operation of the numerical selectors, the non-numerical switch individual to the calling-line is caused to extend the line to the selector after a delay sufficient to prevent false impulses from influencing the selector. The invention is described as applied to a system using line and master switches of the kind described in Specifications 26301/06, 15072/12, a n d 19253/12, and the delayed action of the line switch C is effected by connecting its operating winding 18 in series with a slow-acting relay 22, which, after the desired delay, short-circuits its high-resistance winding 24, so as to allow the winding 18 to operate, the relay 22 remaining energized by its lowresistance winding 23. When the subscriber A removes his receiver, the line relay 14 closes the circuit of the operating-winding 18 through relay 22 and contact 26 of a relay 51, which is energized when the master switch D is in motion. Assuming that the plungers of the line switches C were opposite the terminals of the first trunk E, the master-switch wiper 40 would be in engagement with contact 41, and the locking-arm 42 would engage the first notch 43, and arm 44 with close contacts 45. With the master switch in this position, the closure of contacts 32, 36 energizes the starting-relay 50, which closes parallel circuits through the relays 51, 52, and a supervisory relay 53. The relay 51 removes the locking-arm 42, and opens contact 26 in circuit with the operating-windings 18 of the line switches. The relay 52 closes a holding-circuit for the relay 50, and also energizes the operating- solenoid 55, which rotates the plunger shaft 47 until the sector 46 and wiper 40 reach the position shown in the Figure. The circuit of relay 52 is opened as soon as the plunger shaft moves but its springs are held closed by a detent 57 until tripped by the arm 58. The invention is also applicable to line switches of the rotary step-bystep type.

Title: Gear finishing machine
IPC: B23F19/04
Filed: 1958-06-10
Abstract: 828,046. Gear finishing. NATIONAL BROACH & MACHINE CO. June 10, 1958 [July 11, 1957], No. 18505/58. Class 83 (3). An internal-gear finishing-machine comprises a horizontal work-spindle in a housing 28 connected by a horizontal pivot 30 to a table 24 connected by a similar pivot 26 to the machine base, the pivots being disposed at an angle to one another, and power means for traversing a tool slide towards the work. The tool slide moves on a vertically-adjustable knee 12, and carries an angularly-adjustable tool head 20. A chuck 36 is operated by an air cylinder 34, and is rotated by a motor 42 pivoted to the housing 28, to permit belt-tensioning adjustment. The housing 28 may be adjusted by a screw about the pivot 30 to produce unmodified or slightly tapered teeth. A feed-piston connected to a link 94 can be operated to move the housing 28 about the pivot 26 to engage the work with the cutter. Such movement may be prevented by a cylindrical pin 116 having flat sides, and which can be turned by a knob 114 to engage opposed fixed pins 118. The housing may be locked in any raised position by actuating fluid-pressure means 122, which causes release of two spring- pressed wedges. The wedges move independently on each side of a pin projecting from the housing, until a locked position is reached. This locking-action may be applied periodically so that the work is moved by the pressure of the feed-piston into engagement with the cutter, the housing is locked, the tool traversed, the housing unlocked and advanced towards the tool again, and so on. Instead of forcing the work against the tool by the feed-piston, the weight of the housing may be used under the control of the piston. The tool is of shaving or lapping type, or of a resilient plastic embedded with abrasive. Specification 797,282 is referred to.

Title: Weighing apparatus
IPC: G01G19/14
Filed: 1923-07-21
Abstract: 216,728. Essmann, F. A. A. July 21, 1923. Apparatus fitted to cranes comprises a rod guided by links engaging the framework, the rod being burdened at one end by the load and supported at the other end by a weight - indicating device independently of the links. As shown in Fig. 2, the invention comprises a rod 1 carrying the load pulley 4 of a crane and guided by parallel links 2, 3. The lower end of the rod is supported by a suspension rod 5 connected to a steelyard 8 through a reduction lever 6 and draw-rod 7. A guide pulley 10 is provided at the upper end of the jib A in such a position that the part of the load rope 11 between the load pulley and the guide pulley is parallel to the links 2, 3. In cranes in which the jib is approximately horizontal, the links 2, 3 are inclined, to reduce the load on the rod 1, the guide pulley being arranged to keep the rope 11 parallel to the links. In order that the rod 1 may be as light as possible it is preferably tubular and stiffened by stays, and supplementary links may be arranged between the links 2, 3 to prevent bending. The weighing apparatus may be relieved by lowering the suspension rod 6<x>, the weight of the rod 1 being taken by the engagement of extensions of the spindle of the pulley 4 with the walls of the apertures in the jib A, the said walls being inclined to draw the knifeedge 59 away from its bearing. In a modification, Fig. 5, the load pulley 4 is carried by a frame 13 pivoted to a rod 1, a compression link 14 being provided to keep the frame in position. In a further modification, Fig. 14, the load pulley is suspended from the upper end of the rod 1 by a rod 49 and the links 2, 3 are inclined and arranged in such a position that the rod 1 is in tension. In cases in which the load on the rod 1 becomes excessive, a reduction lever may he interposed between the rod 49 and the rod 1. In applying the invention to a floating crane, Fig. 8, the links 2, 3 are pivoted to carriers 22, 26 respectively which are themselves pivoted by rods 23, 27 to the jib, the rods 23, 27 being in axial alignment. The weighing apparatus is carried by a frame 28 pivotally suspended on a shaft 29 extending from the carrier 26, the line of support of the rod 1 being arranged to coincide with the axis of the rod 29. The weighing- apparatus is thus enabled to accommodate itself to the movements of the ship. As shown in Fig. 10, the invention is applied to a travelling crab. The rod 1 is arranged horizontally and parallel to a track 31 on which the crab 32 travels. The load pulley 4 is suspended from a roller 39 on the rod 1 through a system of reduction levers 36, 37 carried by a framework 35 suspended from the crab. The rod 1 extends over the whole length of the track and is supported at one end by a rod 5 connected to the weighing-apparatus.
