Title: Improvements in electric fuse fittings
IPC: H01H85/20
Filed: 1937-02-25
Abstract: 481,544. Wire couplings combined with fuses.. HOPE, V. Feb. 25, 1937, No. 5639. Addition to 480,690. [Class 38 (i)] In a fuse fitting for a tapping lead from an overhead conductor, comprising a two-part insulating casing enclosing a cartridge fuse 13 held in split-socket terminals 12, of which the lower (not shown) has limited axial movement in the lower casing part 11, as described in the parent Specification, the upper casing part 10 has interchangeable means for the reception of a tapping lead from the conductor or for direct application of the fitting to the conductor.

Abstract: 1492972 Liquid level control GIRLING Ltd 21 Jan 1975 [7 Feb 1974] 05648/74 Heading G1H A probe giving warning of a drop in the level A of liquid in a reservoir 6 below a certain level has one or more baffle plates 8 which prevent or inhibit current leakage due to a conducting film of the liquid being formed by splashing between the probe tip and the earthed mounting, as shown, a filter cap 4. The plates may be so dimensioned that even if themselves covered with the film, the resistance of the path so provided would be too high for significant ourrent leakage.

Title: Improved manufacture of rubber composition
IPC: C08K3/04
Filed: 1929-02-20
Abstract: 307,743. Thermatomic Carbon Co., (Assignees of Spear. E. B.. and Moore, R. L.). March 12, 1928, [Convention date]. Indiarubber compositions. - Rubber is compounded with carbon black produced by a process which consists in thermally decomposing a hydrocarbon gas, for example methane, by passing a mixture of the gas and diluent gas such as hydrogen or nitrogen through a retort containing highly heated checkerwork. The volume of the diluent gas is preferably about five times that of the hydrocarbon gas. The resulting carbon is of black colour similar to ordinary channel black and has the low rubber stiffening qualities of Thermatomic black. Preferably the diluent gas is first strongly heated in a part of the retort and is then mixed with the hydrocarbon gas. The retort shown comprises a casing 14, refractory lining 15, and two zones A, B of refractory checkerwork separated by a mixing chamber 31. The retort is first heated by burning gas therein, and then the diluent gas is introduced at the top to pass down through the zone A and the hydrocarbon gas is introduced through the pipes 32 to mix with the heated diluent gas in the chamber 31. The mixture then passes down through the checkerwork B where the hydrocarbon is decomposed into carbon and hydrogen. Part of the carbon is deposited on the checkerwork, from which it is afterwards burnt, and the rest is carried off by the issuing gases and is recovered. Part of the hydrogen, after removal of the carbon, is used again as the diluent gas and the rest is used for other purposes. U.S.A. Specifications 1,478,730, 1,520,115, and 1,638,421 are referred to.

Title: Improvements in or relating to roundabouts, riding devices, railways for recreation,and the like
IPC: A63G1/24
Filed: 1924-03-06
Abstract: 230,621. Collins, P. March 6, 1924. Roundabouts; railways for recreation.- In amusement apparatus in which a hood or canopy is adapted to be folded or unfolded over the passenger-carrying cars during the motion of the cars, the hood is operated by the action of a ramp 28 which is brought into engagement with a wheel 15 operatively connected with a shaft 3 connected with the hood. The hood 17 is carried by members 17<a> on arms 22 pivotally mounted on each end of the car 1. A quadrant 23 is secured to one end of the arm 20 and the ends of a rope 26 are secured to the ends of the quadrant. One end of the rope 26 passes over a pulley 25 and the rope is drawn tightly over a pulley 24 on the shatt 3, so that the hood 17 is folded or unfolded according to the direction of rotation of the shaft. The wheel 15 drives the shaft 3 through dogclutches 6, 7 and bevel-gearing, and the clutches are operated by a second ramp 21 which is raised to engage a lever 20 connected to the end of a shaft 10 on which forks 8, 9 operating the clutches are mounted. The ramp 28 is operated by a lever 36 through a cable 35 and levers 29. The lever 36 carries a spring plunger 43, the lower end of which has a projection 42 adapted to engage a notch in a lever 40 connected to the ramp 21. By these means the ramp 28 may be operated alone to cause the unfolding of the hood, or both ramps 21 and 28 may be operated together to fold the hood. Springs 18, 34, 38 cause the return of the dogs and ramps to their original position.

Abstract: 859,862. Refrigerators. GOODRICH CO., B. F. Feb. 19, 1959 [Feb. 20, 1958], No. 5782/59. Class 29 [Also in Groups XXV, XXVI and XXXV] The steel door of a cabinet, e.g. a refrigerator, is both held shut and sealed by a hollow gasket containing a flexible magnet (see Group XXXV). The magnet comprises magnetized particles of ferrite in a resin binder arranged in blocks 23 on an adhesive flexible tape 13, and is inserted in a channel 40 in the gasket 38 which is of elastomeric material and has an attachment flange 39. The magnet strip is thinner than the height of the channel so that, when attached to the bottom 41 by staples or an adhesive, a space remains to allow for compression of the gasket when in use. The complete door fastener is made by forming a rectangle of four gasket strips, the corners being mitred and heat sealed. To facilitate this the magnets stop short of the corners and the channel 40 is filled with a packing e.g. of glass wool.

Title: Improvements in Temperature Responsive Electric Switch Mechanisms
IPC: H01H37/36
Filed: 1967-02-07
Abstract: 1,170,517. Thermal switches. GENERAL ELECTRIC CO. 7 Feb., 1967 [8 Feb., 1966], No. 5808/67. Heading H1N. In a temperature responsive switch a temperature sensitive element 30, Fig. 3, contains a partially saturated vapour region and liquid region at the operating temperature range whereby heat transfer takes place within the element 30 during snap-action of the contacts and thermal damping of the switch actuator is obtained to reduce the noise of operation. A bias heater 144 is arranged on the expansible chamber 34 to maintain the chamber at a higher temperature so that the liquid region 39c for heat transfer is always maintained at the heat sensitive end 139. The expansible chamber 34 acts against an adjustable threaded stud 108 in a carrier 109 loaded by coil spring 20a and actuates the switch contact 12 through a pivoted actuating lever 13 and push rod 95. A toggle spring 40 arranged between the actuator 13 and adjusting screw 47 is arranged to override the action of spring 20 and provides a negative spring characteristic to snap the contact 12 open. The bias heater 144 is maintained permanently in circuit but a second pre-heater 140 is arranged between the capsule 34 and the sensitive end 139 and is connected in parallel with the load heater and operates to provide a contact weld-breaking action. Temperature range adjustment is provided by a control knob 28 rotating cam 26 to vary the loading on spring 20a through cam follower 25. The knob 28 also controls a manual " off "  position by camming an arm 100 which depresses a pin 102 operating to hold the contacts open. In a modification, Fig. 1 (not shown), the switch actuating arm has a lost motion connection to a rigid extension of the movable con. tact spring which flexes until the rigid extension engages a fixed stop and withdraws the contact positively. In the examples the capsule is initially filled with butane at a temperature of 54‹ C. and gauge pressure of 60 p.s.i. in order to obtain a saturated vapour state in the operating range of (21-24‹ C.) at which the pressure is 17 p.s.i.
