Title: Improvements in or relating to the formation of an electrical cable having a continuous flexible sheath
IPC: H01B13/26
Filed: 1960-11-02
Abstract: 974,921. Wrapping cores. W. A. PLUMMER. Nov. 2, 1960 [Nov. 2, 1959], No. 37694/60. Heading B8G. [Also in Divisions D1 and H1] An electric cable is sheathed in a wrapping of flat strip material having interlocking edges. Fig. 1 shows the general arrangement of the apparatus. A core is supplied from a drum 36 through the hollow shaft of a rotating bobbin assembly 20 where two further layers of core are applied, over a hauling capstan 27, through a device 12 where the flat strip is supplied from a drum 76 and folded around the cable, through an oven 34 where the strip is shrunk to grip the cores tightly and finally on to a take-up drum 33. A motor 16 drives the bobbin assembly and the capstan 27. A motor 14 drives the take-up drum. Both motors may be controlled from a single station. Core stranding arrangements (Figs. 15 and 16). - Each bobbin is mounted between cores 52 on a stub shaft 45 carried by a stirrup 47, a rubber band 53 braking one of the cores to prevent over-run. Each stirrup 47 is rotated, relatively to the plate 20, by a chain driven sprocket 55. As shown in Fig. 15 there are inner and outer circles of the sprockets 55 driven by chains 56, 66, the drive being such that orientation of the axes of the bobbin remains fixed as the plate 20 rotates. Wrapping the stranded core (Figs. 2, 3, 5, 9, 10, 12).-A plastic strip 77 to be wrapped around the cable core 30 is drawn from the drum 76 which is braked to tension the strip. After passing over a roller 81 the cable is bowed downwardly by an eye-bolt 168 so as to press it into the strip 77 the sides of which are bent upwardly by rollers 160. The two edges 96, 96<SP>1</SP> of the strip 77 are then passed into a shroud 113, Fig. 9, where a nozzle 156 applies adhesive to the edge 96. The shroud is shaped to cause the edges 96, 96<SP>1</SP> to align themselves one above the other, a member 140, Fig. 10, preventing the two edges from contracting prematurely. In Fig. 12 the edges 96, 96<SP>1</SP> are being pressed together by a roller 119. The cable with its sealed cover then passes through an oven 34, Fig. 1, which may contain infra-red lamps, the oven causing the sheath to shrink on to the core. Stop motion.-The entire assembly for applying the sheath is mounted on a frame 84, Fig. 2, that is pivoted against the action of the sheath. Excessive tension in the sheath rocks the frame so that it operates a switch to stop the machine. Specification 974,922 is referred to.

Abstract: 856,564. Retractive switches. HOUILLERES DU BASSIN DE LORRAINE. Dec. 10, 1957 [March 28, 1957], No. 38302/57. Class 38 (5). [Also in Group XXXVIII] A normally closed two-pole pulltype electrical switch for insertion between two lengths of cable is so arranged that when it is fixedly supported a pull on either cable opens both of its poles. It is stated that a plurality of these switches linked together by lengths of cable could be used for a signalling system in a mine shaft, a signal being produced by physically pulling any one of the lengths of cable. Pull on either of the two cables 27 attached to a switch causes lateral sliding motion of a spring-loaded unit 13, 21, 19, thereby moving two contacts 15, 16 away from a fixed member 9 of non-conductive material through which extends a central conductor 10 and an annular conductor 11 which co-operate with contacts similar to contacts 15, 16 in the other half of the switch. The annular conductor 11 together with a bearing 20 allow the member 13, 19 to rotate freely (to take up any twist in the cable) without affecting the electrical properties of the switch.

Delivery apparatus; associating - apparatus; cutting-apparatus. - A web W printed by machines 2, 3 with a, number of different signatures is slit by cutters 4 into a number of separate webs a - - f, Fig. 1, which pass over longitudinal web-folders arranged out of line widthwise of the web, the folded webs being passed sideby-side to sheet-cutting cylinders and delivery trays, each two or more products wide so that each tray collects similarlyprinted signatures. In one form, the webs a, c, e pass over turning-bars 8, 8<1> so as to be superposed on the webs b, d, f respectively and the pairs of webs are led over the formers 9, 10, 11 of longitudinal folders which are placed diagonally so that the webs, after being folded thereby, can be brought together in side-by-side relationship between rollers 15, Fig. 3. Cutting-cylinders 16 of treble width sever the webs into sheets taken alternately by gripper cylinders 18, 19 which in turn fold the sheets thereon alternately into grippers on cylinders 20, 21 and 22, 23 respectively. The cylinders 18 - - 23 are all of treble width to deal with the three sets of sheets, and each of the cylinders 20 - - 23 delivers to three trays arranged abreast of one another as, for example, trays 25 - - 27 in the case of the roller 20. In a modified arrangement for dealing with a web slit into three parts only, the turning- bars 8, 8<1> are dispensed with. The pairs of webs ab, cd and ef may, by suitably arranging the turning-bars, be directed into paths vertically above one another, the formers 9, 10, 11 being placed one behind the other and at different levels.

Title: Automatic device for controlling catalytic mufflers
IPC: F02D41/14
Filed: 1972-08-17
Abstract: 1406876 Controlling treatment systems SNAMPROGETTI SpA 17 Aug 1972 [10 Sept 1971] 38517/72 Heading B1W [Also in Division Gl] A by-pass valve 2 of a catalytic muffler 1 for the exhaust gases of an engine is opened under the control of a circuit 3 when the conditions are such that flow of gases through the muffler would cause damage thereto, the circuit including means responsive to the engine speed, to the degree of throttle opening and to the temperature of the catalyst. As shown in Fig. 2, a voltage representing engine speed from a device 4 is compared with a reference from a potentiometer 6 at the input of a level discriminator 7 which provides a signal to an OR gate for opening the valve when the engine speed exceeds the reference. A voltage representing throttle position from a device 10, e.g. a potentiometer, is compared with a reference voltage from a potentiometer 11 at the input of a level discriminator 9. The output of the discriminator 9 is applied to an AND gate 13 and to a delay means 12 which applies a pulse to the AND 13 a fixed period after it has been triggered. Thus, the AND gate 13 provides an output to a store 14 only when the degree of throttle opening has exceeded a preset amount for a preset time period. The store 14 then provides a continuous signal to the OR gate 8 to open the valve until the throttle positions fall below the preset value when the store is reset via an inverter 15. A voltage from a thermo element 17 is amplified in an operational amplifier 18 and differentiated at 20, 21, the resultant voltage being compared with a reference from a potentiometer 23 representing a temperature at which the catalyst becomes damaged. If the voltage exceeds this reference, a level discriminator applies a signal to OR gate 8 to open the valve. The amplified voltage is also compared at 25 with another reference from a potentiometer 26. If the voltage exceeds this reference, the voltage increase is applied via relay contacts 27 to an integrator 29, the integrated voltage being compared with a reference from a potentiometer 30. If this voltage exceeds the reference, a level discriminator 31 applies a signal to a store 32 which then applies a continuous signal to the OR gate 8 to open the valve. Thus the valve is opened if the temperature of the catalyst exceeds a reference value (potentiometer 26) for a preset period of time (potentiometer 30). The output of OR gate 8 is applied to an OR gate 35 and a timer 34 whose output is also applied to OR gate 35.
