Patent GB-573805-A (GB)
Title: Improvements relating to the production of resins
IPC: C08F6/12
Filed: 1943-12-16
Abstract: Recovering polystyrene, polycoumarone or polyindene resins of high melting points from naphtha in which the resins have been produced by polymerization, by the fractional precipitation of the resins with the aid of a solvent or mixture of solvents in which the naphtha is soluble and the resins substantially insoluble.  Thus, to the naphtha solution of the resin is added an equal volume of n-hexane and the precipitated resin removed.  A further volume of n-hexane gives a second precipitate of lower melting point.  If a catalyst such as aluminium chloride or boron trifluoride has been used for the polymerization, a co-ordinated complex of resin and catalyst is precipitated which is freed of catalyst by washing, e.g. with weak acid or soda.  If the unpolymerized naphtha solution contains a large amount of potential resin it is diluted with some of the solvent; if it contains very little it is concentrated by a partial steam distillation.  Solvents are those of the paraffin and cyclo-paraffin series, such as aliphatic or cyclo-paraffinic hydrocarbons, alcohols, ketones, esters, acids, acid anhydrides, ethers, chlorohydrins and amines.  Pyridine and its derivatives may also be used.

Title: Improvements in and relating to electric motor and like controllers
IPC: H01H25/04
Filed: 1950-09-01
Abstract: 689,328. Controllers. WILLIAMS, H. M. Aug. 30, 1951 [Sept. 1, 1950], No. 21594/50. Class 38 (iii) The operating handle 1 of a controller is mounted in a ball and socket pivot 3 which is set in parts 4 and 5, the latter having depending portions 10 retaining a movable plate 11 flatly upon a fixed shelf 12. A rectangular aperture 13 is formed in the member 12 to clear the extension 14 of the handle during operation, and the shelf carries spring-loaded balls which co-operate with recesses in the movable plate so as to retain the plate in particular operative positions against small forces tending to displace it. The extension of the handle passes through a circular orifice 26 in the plate 11, stops 27, 28, being fixed to the shelf 12 so that the handle is constrained to follow particular paths when moved from one operative position to another due to the engagement of the sides of the plate with the controller body and the engagement of the stops with the dies of apertures 37 in the plate. The extension 14 carries switch fingers 29, 29a, adapted to engage a number of studs embedded in the walls of the controller. The motion of the controller handle may be constrained by means of a fixed plate having a shaped aperture, Figs. 7-10 (not shown). The extension of the handle may carry a blade contact adapted to engage fixed spring contacts. The handle may also carry a part for actuating an additional micro-switch. The controller may be used for the regulation of the speed and direction of a series traction motor in combination with footoperated apparatus. The application to tap-changing of transformers is also referred to.

Title: Improvements in pattern control mechanisms for warp drawing in machines
IPC: D03C3/24
Filed: 1947-08-07
Abstract: 655,669. Warp drawing-in machines ; jacquards. BARBER COLMAN CO. Aug. 7. 1947, No. 21637. Convention date, April, 28, 1944 [Classes 142(i) and 142(ii)] Selective rotation of heddle release and separator shafts 11, 12, Fig. 5 (or other devices) is controlled by pattern mechanism. A pinion 19 splined on each shaft 12 is normally clear of a rack 16, rotation being then prevented by dogs 23 engaging a fixed' slot 24. When the pattern mechanism (described below) pulls a rod 21,. the pinion meshes with the rack 16, which then makes a to-and-fro reciprocation, after which the dogs 23 again enter the slot 24. Pattern mechanism, Fig. 9. As a pattern cylinder 27, together with a slide 77, moves to the left, a feeler needle 28 registering with a hole in a pattern sheet 26 remains undisturbed, a notch 100 being kept in engagement with a fixed rib 99 by a bar 32 which is sprung upwards for this purpose. But if a needle is pushed to the left by a blank on the pattern sheet. it is forced downwards by bevels on the notch 100 and rib 99, so that a shoulder 192 engages a rib 103 on the slide 77; continued movement of the slide then pushes the bar 32, the push being transformed into a pull on the rod 21, Fig. 5, by rack teeth on both parts meshing with a common pinion. The pattern cylinder 27 and the slide 77 then return to the right, where the pattern cylinder, meshes with a segment 55, Fig. 6a, which is oscillated to turn the cylinder, the return stroke of the segment being delayed until the pattern cylinder has again moved to the left; a plunger 58 locates the cylinder when it is out of mesh with the segment. To enable the cylinder to be turned manually, the segment 55 can be withdrawn by a handle 64. The feeler needles 28 may be integral continuations of the bars 32, in which case the pattern sheet 26 provides .the force for pushing the bars 32 to the left, the slide 77 merely returning them to the right.

Title: Improvements in and relating to electric cables
IPC: H02G15/26
Filed: 1934-07-25
Abstract: 440,380. Cables; sleeve couplings. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. July 25, 1934, No. 21791. Convention date, July 26, 1933. [Classes 36 and 38 (i)] To prevent fatigue of the lead-cable sheath in a pressure cable installation, the pressure gas filling the pipe line is admitted to channels within the cable so that internal pressure equal in value to the pressure existing in the pipe line is applied to the lead sheath and repeated distortion of the sheath due to expansion and contraction of the dielectric of the cable is thereby avoided. The channels within the cable may be formed by the spaces between the strands of the conductor, or by the space within a hollow conductor or a conductor from which one or more strands have to be removed, or by providing a space between the conductor insulation and the lead sheath. Preferably, however, the conductor is insulated with a wrapping of paper 20, Fig. 3, which has been pre-impregnated with a varnish having a high setting point; and which is applied to the conductor so as to leave channels 25 between the turns of the wrapping. In order that the pressure gas within the pipe line may have access to the pressure channels of the cable, a helical tube 28, Fig. 4, is embedded in the insulation 29 surrounding a joint between two lengths of the cable, the inner end of the tube communicating with the pressure channels and the outer end opening into the joint casing 30 which, as shown in Fig. 6, is accommodated within an enlarged section 35 of the pipe line. The pressure gas enters the casing 30 through an aperture 31 in the casing. In installing the cable, the pipe line is first dried and then evacuated, being subsequently filled with dry inert gas, and the cable then pulled into the pipe line through a rubber gland 42, Fig. 7, attached to one end of the pipe.

Title: Improvements in telephone systems
IPC: H04M9/00
Filed: 1921-08-17
Abstract: 193,074. Hastings, R. C. M. Aug, 17, 1921. Manual exchange systems; party-line systems and apparatus.-In a common battery manual exchange system, the insertion of the operator's calling plug into a subscriber's multiple jack causes a step-by-step device at the called substation to close a switch to connect the call-bell in circuit with the exchange battery. The invention is described as applied to a system in which the talking and supervisory circuits are arranged as in common practice. The insertion of the operator's calling plug 100 into a multiple jack 200 completes a circuit 55, 41, 79, 77, 8 for a relay 9, the armature 5 of which wipes over a contact 4 and thereby sends an impulse from a generator G to a stepping magnet 17 at the called substation. The magnet 17 advances a ratchet 37<1> and disc 39 one step, causing a pin 39<1> on the disc 39 to close two contacts 28, 29, thereby ringing the call-bell 22 in a circuit 41, 79, 77, 12, 15, 22, 23, 34, 14, 13, 76. The contacts 28, 29 are closed by a pin 39<1> at every second step taken by the disc 39. When the called subscriber removes his receiver the momentary closure of contacts 24, 64 energizes a relay 33 over circuit 41, 77, 12, 70, 72, the relay 33 locking up over its right-hand armature and interrupting the ringing circuit at its armature 31. The call now proceeds in the usual manner. When conversation is finished and the plug 100 is removed, the holding circuit of the relay 33 is broken, but the relapse of the relay 9 again momentarily closes contacts 4, 5 and an impulse is sent to the magnet 17, which rotates the disc 39 another step and causes the ringing circuit to be opened at the contacts 28 29.

Title: Improvements in circular knitting machines
IPC: D04B9/06
Filed: 1919-09-09
Abstract: 145,396. Wilcomb, J. F. June 20, 1919, [Convention date]. Circular machines. - Comprises an improved rib-knitting machine organization in which the form of knitting-unit described in Specification 141,660 is employed. The improvements are applicable in part to machines with a single row of needles. The needle unit comprises a needle member having a hook 2 and a stem 1, and slidably mounted in a quill comprising a stem 4 of channel form for receiving the needle, a nose 5, rise 6, swell 7, drop 8, throat 9, butt 10 and a stop 11 fixed or riveted between the walls of the stem. The dial needle butts 3 can be operated nearer the verge or in a circle of a larger radius than heretofore owing to the absence of latches and to the construction of the dial with a channel 14 into which the needle hooks recede and draw loops, also the dial cams can be of smaller angle than cams set nearer the centre and a larger number of knitting-units per inch can be provided. The web holders 12 have blunt inwardly projecting noses 13 which hold the dial loops in a definite position on the needle stems leaving just enough space for the fabric to pass down. The web-holder dial mounting is designed to avoid the accumulation of lint and comprises an outwardly extending ledge 16 of the needle cylinder to which the web-holder bed 17<1> is clamped by a plate 17 and screw 18. Sinkers 19 operated by a cam 20 may interlock with the web-holders 12, which are forced inwards by a spring band 24 and have shoulders engaging projections of the sinkers. The swells 7 of the dial quills serve to keep the fabric loops separate from the newly fed yarn during the period when the needle hook is entering the swell. The needles are constructed of thinner material than it is practicable for latch needles do be as they are supported in the elevated position by a prolongation 15 of the dial needle slot and by the quills at all times. This allows more space for the yarn and for the passage of lumps &c. and there is less liability of imperfections occurring in the fabric. A single row of needles may be supported in the same way by relatively fixed needle guards or supports for resisting the thrust of the yarn.
