Title: Improvements in or relating to press for shaping and vulcanizing pneumatic tires
IPC: B29D30/36
Filed: 1955-03-17
Abstract: 769,365. Moulding tyres. McNEIL MACHINE & ENGINEERING CO. March 17, 1955 [Aug. 3, 1954], No. 7799/55. Class 87(2). A press for moulding tubeless or other tyres without the use of a diaphragm or air bag includes a pair of bead-clamping rings 35, 36 that are moved apart, during the descent of the upper mould section 2, from the closed idle position shown in Fig. 2, to the open beadclamping position shown in Fig. 3. In the clamping position the rings force the beads M of the tyre band B along tapered surfaces 3 on the mould sections 1, 2, firmly seating the beads in the sections and preventing loss of curing steam that is introduced into the formed band and brought into direct contact with the inside surface of the band. The bead rings are moved apart by high-pressure steam which is introduced through pipe 54, some steam passing through passages 36 in the bead rings into the formed band to shape and cure it, and other steam passing through a passage 52 into a cylinder 50 where it depresses a piston 70 and rod 73. This rod has fixed thereto a collar 78 to which are pivoted four levers 84 which, as the rod descends, rock about fulcra F on the inner edges of bead ring 36, the free ends of the levers being thus raised to bear upwardly against the bead ring 35. When, after curing, the press begins to open, Fig. 4, residual pressure inside the tyre T raises the bead ring 35, a rod 105 attached to the ring sliding upwardly within rod 73, the tyre being thus stripped from both mould sections and the condensed water in the tyre draining away through passages 36. The pressure inside the tyre and cylinder 50 is then completely exhausted through pipe 55, whereupon bead ring 35 falls to its initial position, then hydraulic pressure is introduced into cylinder 50 through pipe 63 to raise both bead rings and the tyre, as shown in Fig. 5. U.S.A. Specification 2,699,572, is referred to.

Title: Improvements in or relating to a windshield cleaner
IPC: B60S1/10
Filed: 1955-03-17
Abstract: 767,076. Oscillating-vane and vacuum engines; engine valve gear. TRICO PRODUCTS CORPORATION. March 17, 1955 [April 8, 1954], No. 7874/55. Classes 110 (2), 122 (2) and 122 (3). A motor for a windscreen wiper mechanism, actuated by vacuum or pressure on one side of a vane, and atmospheric air on the other, is provided, in addition to the normal reversing- valve means, with an additional valve mechanism which controls the retardation of the vane at the end of each stroke to prevent hammering on the chamber ends. This is effected by opening to atmosphere and subsequently closing, during each vane stroke, that side of the working chamber which is not in communication with the source of vacuum or pressure. The Figures show a vane 50 fixed to a shaft 10 carrying a lever 11. The latter is turned through an angle and contacts a shoulder 13, Fig. 3, and then carries a member 12 with it until a spring toggle mechanism 24 crosses its dead-centre position. The member 12 is then snapped rapidly to its extreme counterclockwise position to reverse the vacuum and atmospheric air connections to the working chamber, through actuation of a reversing valve 15. An operating valve 17 connects appropriate pairs of passages 20 ... 23 with the working chamber on each side of the vane 50. A housing C contains the additional valve mechansim, comprising a face plate integral with the housing, the plate being provided with a port 26. A driving valve element 30 is fixed to the shaft 10 and coacts with a member 27 rotatable on the shaft 10. A cover-plate 31 encloses the assembly. Atmospheric air is drawn into the housing C through louvres (not shown) and passes through a filter 32 to a groove 33, under control of the member 27, and into a port 34, in the centre of the groove 33 and through a perforated gasket 25 into the reversing-valve chamber. When the motor is started, the vane 50 and shaft 10 and element 30 move in a counter-clockwise direction, but the member 27 remains stationary at first so that a hole 29 is brought into registration with parts 26, 28,. thus providing an unrestricted flow of atmospheric air into the working chamber. Lugs 35, 37 on the element 30 coact with a tongue 36 on the member 27 to control the registration of ports 26, 28, 29. The vane and its shaft rapidly reach maximum velocity at the beginning of a stroke, and are gradually retarded as the end of a stroke is reached. A passage is provided to by-pass the additional valve mechanism, for parking the motor.

Title: Improvements in or relating to the treatment of carbonaceous material
IPC: C10G32/02
Filed: 1937-03-18
Abstract: <PICT:0492297/III/1> In the distillation of carbonaceous materials such as coal, shale, crude tars and crude oils, the distillation is carried out at a temperature not exceeding 350 DEG  C. and the volatile matter is passed through an electrostatic precipitation device having nondischarging electrodes connected to a source of unidirectional potential.  The volatile matter from the retort may be passed through the supplies of material to preheat it, and some of the volatile matter from the precipitation may be passed through the retort in counterflow to the charge.  Apparatus in which the process may be carried out is shown in the Figure and p  comprises a retort 10 fitted with a worm conveyer 11 and internal heater 12.  The charge is fed from a hopper 13 and after progressing through the retort is discharged by way of a hopper 16 to a pit.  The volatile matter from the retort passes through the charging hopper and by way of the pipe 21 to the precipitator 20, the electrodes 24 of which are supplied with pulsating unidirectional potential by means of a transformer and rectifying valves, or by means of a source of direct potential.  The volatile matter from the precipitator passes by way of the pipe 23 to a gasometer and part may be led back to the retort by the pipe 19. Oil is discharged from the sump 25 at the bottom of the precipitator. In treating shale the retort is maintained at a temperature not exceeding 350 DEG  C. and when the volatile products from the precipitator are returned to the retort, the processing temperature may be reduced to 200 DEG  C.  The corresponding temperatures for coal are 200 and 170 DEG  C.

Filed: 1973-02-19
Abstract: 1418995 Rollers USM CORP 19 Feb 1973 [18 Feb 1972] 7958/73 Heading F2U A calender roll comprises a stationary shaft 16 held at its ends by supports 23, a roll shell 12 rotatably-mounted with a clearance on the shaft as by bearings 18, and a drive 11 which rotates the roll shell through a gear train including a pinion 41, a ring gear 50 and a connecting means 52 which is provided with external gear teeth 54. The supports 23 allow bending of the shaft under load and the gearing arrangement allows axial displacement of the shell 12 when this moves vertically as a result of the deflection of the shaft. If desired, the deflection may be preset to that expected. As shown, the pinion 41 is mounted at one side of the gearwheel 26 of the drive 11 and the connecting means consists of a toothed flange 52 bolted to the shell 12, the ring gear 50 being provided with external and internal teeth 51, 53. The clearance space between the shell and shaft is used in the art for the introduction of fluid pressure into partitioned-off areas at that part of the shell subjected to deflection forces during calendering; the shaft only consequently deflects. In a second embodiment, Figs. 3 and 4 (not shown), two pinions (41, 41<SP>1</SP>) are provided one each side of the driving gear-wheel (26) and the connecting means between the ring gear (50<SP>1</SP>) consists of a sleeve coupler (70) having external teeth (71, 72) meshing with the ring gear and a flange (74) bolted to the shell. In a third embodiment, Figs. 5 and 6 (not shown) three pinions (41) are equi-spaced about the driving gear-wheel (26).

Title: Telecommunication systems
IPC: H04M15/08
Filed: 1944-04-28
Abstract: 600,458. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. April 28, 1944, No. 7992. Convention date, June 21, 1943. [Class 40 (iv)] Each finder of a set of common first identification finders in a system similar to that described in Specification 592,846 is arranged to stop when it finds any of' a number of potentials applied over the normal switch train to the T-terminal by a wire chief, automatic ticketing equipment, a special service operator, either of two toll operators and a portable test set respectively, the second identification finders associated individually with these services stopping only when they find the potential distinctive of that service. When any of the potentials in question is applied (by keys IK1 or IK2 or relays IR1 ... IR4) to the T-circuit, the relay GSR of the group containing the calling line starts the corresponding first identitication finder which hunts in the ordinary way under control of its test relay TR, which responds to any of the possible markings and energizes a relay AR to extend the marking to the banks of the second identification finders. The finder corresponding to the operated relay IR or key IK is already in motion and stops when its test wiper TB, Fig. 2, encounters the voltage characteristic of the service in question, since in that case no current flows in a pair of vacuum tubes V1, V2 and the resulting rise in voltage allows a gas-filled tube GV to break down and energize GVR. In a modification, Fig. 3 (not shown), the application of a characteristic potential to the T-wire is used also to cause the association of repeaters and ticketing equipment with such calls as need them and to cause the transfer of a call from one operator to another. Rectifiers are provided where necessary to prevent the operation of the finder circuits by metering potential and vice versa. Specification 577,088 also is referred to. The Specification as open to inspection under Sect. 91 comprises also an arrangement whereby the application of characteristic potentials to the T-wire of a jack circuit causes the finder of a junction leading in a desired direction to make connection with the jack. This subject-matter does not appear in the Specification as accepted.

Abstract: 1513923 Measuring fluid-flow electrically R JENKINS 19 Feb 1976 [28 Feb 1975 12 July 1975] 8378/75 and 29378/75 Heading GIN The rate of flow of liquid through a conduit is determined by measuring the depth of liquid in the conduit using a vertical array of heated thermistors whose individual temperature and resistance shows if the thermistor is above or below the liquid level. The thermistors 12 are cyclically scanned by a timer 10 and each resistance is compared with a reference value to produce a 0 or 1 signal on a shift register 13, the number of 1 signals, corresponding to the liquid level, being stored in a counter 14. This number is multiplied by a constant introduced at 15 corresponding to the shape of the conduit and the product representing rate of flow is displayed at 16. Further displays 19, 18, 17 indicate respectively total flow; maximum flowrate and the number of times the maximum flow exceeds a pre-set value. The thermistor array 12 may alternatively comprise thermally operated relays. Each sensor is energized for a short period before connection to the shift register 13, whereby the temperature of thermistors below the liquid level is effectively unchanged.

Abstract: 350,570. Hasp fastenings. DARWEN & CO., Ltd., J. S. and TOWLER, H. W. J., 38, Featherstone Street, City Road, London. March 15, 1930, No. 8392. [Class 44.] An attache case &c. fastening of the kind in which a spring-pressed bolt engages an eye &c. on the hasp member has an auxiliary latch capable of movement independent of the main bolt, a continued retracting movement of the auxiliary latch serving positively to retract the main bolt in the event of the main spring being broken. Normally the main and auxiliary latches operate simultaneously. As shown, a lock having the usual slidable keyhole boss 2 connected by members 7, 8 with the bolt 9, the bevelled end 11 of which engages the eye 12 of the hasp 13 in the ordinary way, has a slidable latch plate 1 mounted under the boss 2 and in front of the lock plate 3. The latch 1 has an aperture 4 allowing passage of the usual key, and slots 5, 6 co-operating with members 7, 8 to guide the latch in a direction parallel with that of the main bolt 9. Slots 5, 6 allow latch 1 a limited independent movement, but a continued retraction of.member 1 causes the end of slot 6 to engage with member 8 and positively retract bolt 9 in the event of breakage of the main spring 15 which shoots bolt 9. Plate 1 is urged to shot position by a spring 17 coiled round member 8 and having one end bearing against the wall of boss 2, the other end bearing against a projection 18 on plate 1. The outer end of plate 1 is bent to provide an inclined portion 16 so that as the hasp 13 is pressed home, the end 16 is first pressed back by, and then snaps over, the edge of the hasp. A modification using an arcuate spring is described, and in further modifications the auxiliary latch is spring-urged with reference to the lock casing. In one of these a pivoted latch is used, the pivoted member extending perpendicularly across the path of boss 2.
