Filed: 1947-10-09
Abstract: 643,746. Aerial ropeway clip. LOWE, C. S. Oct. 9, 1947, No. 27197. [Class 78 (ii)] A gravity-operated ropegripping mechanism for the carriage of an aerial ropeway or the like (Fig. 1) having a hanger carrying the load, comprises a rope - gripping device having two jaws 18, 24, whereof one (18) is fixed and the other (24) is movable in relation thereto, and a cam-member 34 is arranged to move the movable jaw into gripping engagement with the rope situated between the jaws, characterized in that an abutment 70 which is movable in relation to the carriage and to the hanger is arranged to take up the reaction of the cam when it operates to move the second jaw for closing the ropegripping device. Fig. 1. The ropeway-carriage (not shown) is integral with upper part 12 of the hanger and the load is attached to movable lower part 14, the relative movement causing jaws 18 and 24 to grip or free the rope. Fixed jaw 18 is part of the arm 22 fixed to the upper part 12. Jaw 24 is pivoted at 28 to duplex link 36, the link 36 at its other end carrying a roller 40. Movement of cam 34 opens and closes the jaws, there being a return compression spring 46. Cam 34 is securely carried by lower hanger part 14 which is moved downwards by the load attached to stem 54 so that the jaws grip, and is moved upwards by shunt rails (not shown) which contact wheels 62 carried on axle 58 journalled in lower part 14 and press the latter upwards and so open the jaws. The reaction of the roller 40 upon wedge 34 is taken by thrust-block 70 which pivots in a semicircular hole in fixed portion 22 and is resiliently held by threaded pin 82 which is screwed into the portion 22 and carries a spring 86 between its head and the thrust-block. Fig. 5. The thrust-block 70 is shown similarly pivoted to fixed part 88 and taking the back thrust of roller 40 upon wedge 43. Fixed jaw 18 is a part of arm 22 which is part of fixed upper hanger part 12. Movable jaw 24 is pivoted at 28 to fixed jaw 18 and is pivoted at 30 to and motivated by duplex link 36 furnished with the roller 40 which is moved backwards and forwards by the vertically-sliding wedge 43 forming part of the movable lower hanger part 14 to which the load is attached. Otherwise operates like Fig. 1. Fig. 6. Carriage 90 runs on its rollers 94, and carries fixed jaw 98 and movable jaw 100. In slots 110 in the carriage 90 moves shaft 112, which shaft is pressed upwards when rollers 114 thereon contact shunt rails (not shown) and otherwise moves downwards under the weight of hanger 111 carrying the load. Shaft 112 carries adjustable cam 120 which contacts roller 104 fixed on the movable jaw 100 and so opens and closes the latter. The thrust between roller 104 and cam 120 is taken by the thrustblock 70 pivoted in 126 and resiliently held by a screw and spring. Fig. 4. Thrust-block 70 has faces 72, 74 with the same centre of curvature 73 and face 78 which is highly curved. Specification 600,876 is referred to.

Title: Improvements in or relating to automatic couplings for railway or the like vehicles
IPC: B61G3/16
Filed: 1926-11-04
Abstract: 271,333. Chandabhoy, N. K. N. Nov. 4,1926. Couplings, automatic. - An automatic coupling for railway vehicles comprises a coupling hook member 14 pivotally mounted at 11 in the buffer head 1, the coupling hook being adapted to engage with a pin 12 on the opposing buffer head and to be locked thereon by a shoe 15 pivatally mounted on the hook member. Each shoe 15 is connected to a collar 26 loosely mounted on a rod 24 by a link 16, a lever 17, a link 18, a lever 19 and a link 29 and the cranked end of the hook 14 is connected to a loose collar 23 on the rod 24 by a link 22. A spring 28 bears at one end on the buffer head and on the collar 26 at the other whilst a spring 27 is interposed between the loose collar 23 and a fixed collar 25 on the rod 24, the collar 23 being adapted to move before the collar 26 during the coupling operation. On the link 18 is a spring 20 placed between a fixed collar 21 on the link and an abutment on the hook so that the shoe 15 is retained in the unlocked position when the coupling hook is in its inoperative position. The rod 24 is provided with a sliding collar 36 secured by a removable cottar pin 31 which is removed, as shown in the right hand side of the Figure, during shunting operations to render the coupling inoperative. In coupling the buffer heads contact and each recedes towards its respective headstock. This brings the collar 36 into contact with the headstock and moves the rod 24 forwardly relatively to the buffer head causing the collar 23 to drag the link forwardly and turn the hook 14 into engagement with the pin 12 of the opposing coupler. The collar 26 is then engaged by the rod 24 and is moved forward to operate the link 29, lever 19, link 18, lever 17 and link 16 to turn the shoe 15 around the pin 12 to lock the hook 14 in its coupled position. When this has occurred recesses in the rod 24 have moved into register with spring plungers in a disc 30 so that the rod 24 is locked in relation to the buffer head. The hooks 14 are uncoupled by revolving the discs 30 so that the spring plungers are forced out of the recesses to allow the rod 24 to be pushed back by the action of the springs 28, 27. Combined buffing and drawsprings 3, 7 bear upon collars 4, 2 placed between abutments on the underframe of the vehicle, the springs 7 being arranged to absorb the initial part of an buffing or draft shock.

Title: Improvements in or relating to presses for drawing sheet metal or the like
IPC: B21D24/14
Filed: 1939-10-13
Abstract: 533,178. Cupping. MACMILLIN, H. FOct. 13, 1939, No. 27872. Convention date, Oct. 17, 1938. [Class 83 (iv)] A sheet metal drawing press comprising a main slide 16, a second slide 30, and a work holder 42 detachably connected to the slide 30 by rods 40 passing through holes 41 in the main slide. The work-piece 13 is placed on the matrix 12 and a valve 51 is operated to admit liquid from a pump 48 and tank 47 to the upper end of a cylinder 20 and exhaust the lower end. This causes the piston 18, slide 16, and a detachable punch 15 to descend and, with these, a slide 33 and hold-down 42, attached thereto by rods 40. Plungers 27 attached to the slide 33 are thus drawn out of cylinders 25, liquid being admitted thereto by non-return valves 56. When the holddown 42 engages the work it is arrested and, as the slide 16 continues to move, acting on the work, liquid in cylinders 36 above heads 44 of the plungers 27 is forced through a passage 45 into the cylinders 25. At this moment an arm 64 of the slide 16 engages a stop 63 thus closing an exhaust pipe 59 which leads from non-return valves 58 and the cylinders 25, so that the pressures in these cylinders, which is indicated by gauges 66, increase to values determined by the setting of adjustable relief valves 67 or safety valves 69. These pressures, acting on the ends 70 of the plungers 27, cause the holddown to act with any desired pressures on the work. After drawing, the valve 51 is reversed, the slide 16 rises to strip the work, then the arm 64 releases the stop 63, the valve 60 opens, the slide 16 engages shoulders 71 on the rods and lifts the slide 33 &c, some liquid from the cylinders 25 being discharged into the bores 36, the bulk being freely discharged during the first part of the up stroke, but through the valves 58 and 60 during the latter part. If unequal pressure in the cylinders 25 is not desired the valves 58 may be omitted and only one valve 67 be used.

Abstract: 733,684. Heating liquids electrically. SCHMIDT, G. Nov. 29, 1951 [Nov. 30, 1950], No. 27983/51. Class 39 (3). [Also in Group XXXVII] A cup-shaped vessel 4 containing water for heating a feeding bottle 14 or like liquid container immersed therein has an exterior layer of insulating material and a heating resistance wire 6 wound on and partly embedded in the insulation on the lateral wall, controlled by a thermostatic switch 10 in contact with the underside of the vessel 4, which is so constructed as to conduct such a quantity of heat to the switch 10 as to compensate for the delay of operation of the switch which would occur if the operation depended solely on heat transference from the liquid in the bottle. The switch and the contents of the bottle are thus brought simultaneously to the required temperature. The vessel 4 may be of glass or a metal of low heat conductivity, e.g. iron or steel or may be of artificial resin preferably with particles of copper or aluminium therein to give the desired heat conductivity. If the vessel 4 is of copper, a further layer of insulation is applied to the base. A small auxiliary resistance strip in parallel with the heater 6 may be placed below the thermal switch 10 to effect a more rapid actuation. The switch 10 comprises a folded bimetallic strip 16 soldered at the fold to a copper gauge strip 17 providing good heat conductivity and connected by a lead 9 to the heater 6. The switch contacts comprise a nickel strip 23 soldered on one arm 22 of the bimetal strip, and two tungsten rods 20 are supported on insulation 19 on the other arm 18 of the bimetal strip. The auxiliary resistance may be placed between the arms of the bimetal. The vessel 4 is supported on a rubber ring 5 in a container 1, which is attached by a bayonet joint 2 to a base 3 carrying a supply cable 8 and a pilot lamp 12 in series with the switch 10. Specification 668,148 is referred to.

Filed: 1969-06-03
Abstract: 1276161 Colour television ELECTRONIC RESEARCH CORP 3 June 1969 28117/69 Heading H4F [Also in Division G5] Relates to a magnetic recording system in which colour sequential video signals are recorded in parallel tracks on a magnetic tape and in which each adjacent pair of tracks is played back simultaneously. In a first embodiment, Fig. 5, the scanning disc 2 has a pair of additional heads 60 and 70 vertically spaced by one track width w from the conventional heads 6 and 7. In the record mode field sequential colour information is recorded using heads 6 and 7 (or heads 60 and 70), a red even field being recorded in a first track by head 6, a blue odd field by head 7, a green even field by head 6, a red odd field by head 7, a blue even field by head 6, a green odd field by head 7, &c. In playback the complete signal train from heads 6 and 7 is passed through one preamplifier and demodulator and the same signal train but delayed by one field from heads 60 and 70 is passed through another preamplifier and demodulator (Fig. 7, not shown), the resulting demodulated signal being gated into three channels for the red, green and blue signals with a normal and a delayed field signal being present in two out of every three field periods. In a second embodiment the head configuration is as shown in Figs. 8 and 9 with the normal head 6 and head 9 spaced 180 degrees from head 70 and head 80, and # degrees from head 80 and head 70 respectively, and head 80 and head 70 stacked {w-(#/180 degrees)w} above head 6 and head 9 respectively. With the signals being recorded by heads 6 and 9 in parallel the vertical interval periods 14a, 14b, 14c &c. are alternately staggered as shown in Fig. 10 and the first interval period 12b 2 , 12d 2  &c. recorded by head 9 comprises the same information e.g. sync. pulses, as that recorded at the end of tracks 12a, 12c &c. During playback head 80 for example will scan this information when tape contact with head 9 is lost, so that no difference is detected between the actual vertical interval and that which would be present in the preferred configuration of Fig. 5. With this arrangement switching between the heads which takes place during the vertical pulse period does not effect the actual picture content. Reference is made to recording line sequential colour video signals. Half as many heads may be employed with the tape traversing 360 degrees instead of 180 degrees of the scanning assembly.
