Title: Electrical switch
IPC: H01H9/00
Filed: 1974-12-24
Abstract: 1526208 Mechanical switches LUCAS ELECTRICAL CO Ltd 8 Dec 1975 [24 Dec 1974] 55750/74 Heading H1N A switch for a vehicle hazard warning system, for example, has a rectilinearly slidable operating member 13 with two conductive bridges 24 and 25 each co-operating with a respective pair of fixed contacts 15, 16 and 17, 18 in a body 11 so arranged that in a first position of member 13 one bridge 24 interconnects its fixed contacts 15, 16 while the second bridge 25 is out of engagement with at least one of its fixed contacts, and in a second position of said member 13 the second bridge 25 interconnects its fixed contacts 17, 18 while the first bridge 24 is held out of engagement with at least one of its fixed contacts by a ramp 27 carried by the body 11. In the embodiment shown the bridge 24 is a brass plunger and bridge 25 is a brass plate each being urged outwardly by a common spring 26 therebetween, the plate 25 being shaped, at 25b, for additional engagement with one contact 19 of a further pair of contacts 19, 22 and member 13 carries a lamp (14, Fig. 3, not shown) which has one contact in permanent sliding engagement with a contact 21 and its other contact connected to a resilient conductive member having arms 28, 29 co-operating with fixed contacts 19, 22. The fixed contacts 17, 18, 19 are shorter than contacts 15, 16, 22 such that in the first position of member 13 the moving contacts 25 and 29 do not engage them, while in the second position of member 13 ramp 27 lifts plunger 24 away from both fixed contacts 15, 16 and another ramp (31) lifts contact 28 away from contact 22. Detent members (not shown) locate member 13 in its two positions. In a second embodiment (Figs. 4 and 5, not shown) the moving contacts comprise conductive balls (53, 54, 55, 56), mounted at the free ends of resilient blades (51, 52) carried on the slidable operating member, to interconnect fixed contacts 42, 43, 44 and 45, 46, 47 respectively. In this embodiment the operating member is provided with a return spring (49) and is located by a detent mechanism (not shown) of the push-push type. In each embodiment the fixed contacts extend through the base of the switch body to form terminal pins.

Title: Rotary kiln apparatus with suspension pre-heater having burner for calcining
IPC: F27B7/32
Filed: 1973-12-05
Abstract: 1413055 Combined rotary kiln and preheater ISHIKAWAJIMA-HARIMA JUKOGYO KK 5 Dec 1973 [6 Dec 1972] 56440/73 Heading F4B A rotary kiln 2 with integral rotary multicylinder precooler 31 in combination with a material preheater with fuel burner 5 in which clinker is precooled by combustion air induced through the precooler 31 and combustion air for the preheater is supplied by a duct 82 from the clinker main cooler 32. Blower 7 supplies cooling air to the main cooler 32 and air not taken by the preheater 1 is discharged through the vent 9. Each precooler cylinder has a weir 12 so that clinker is discharged at the highest position of rotation on to the inclined surface 10 which facilitates uniform distribution of clinker over the grate. In a modified version, when it is not required to cool clinker to less than 100‹ C., the main cooler may be divided into high and low temperature zones and cooling air supplied to the low temperature zone is then sent to the suction side of the cooling air for the high temperature zone. Under the same criteria of clinker temperature, a counterflow type rotary cooler may be used instead of the grate type cooler.

Abstract: 1271006 Electric infrared radiators THERMAL QUARZ-SCHMELZE GmbH 5 Dec 1969 [20 Dec 1968] 59623/69 Headings F4W and W61 An infrared surface irradiator comprises a casing 1 accommodating a plurality of electrically heated quartz tubes 5a-5g of different thermal outputs. The different outputs are obtained, e.g. by having high temperature heating filaments 7 in some tubes 5a, 5c, 5e and 5g, and filaments 7 of lower temperature in other tubes 5b and 5f. Tube 5d is without a filament and is thus heated only indirectly, itself then radiating at a wavelength corresponding to a lower infrared region, and providing an alternative way of obtaining a different thermal output. The quartz tubes may be of flattened section, as the tubes 12, Fig.5, with two lengths of filament 7 separated by quartz tubes 13. Indirectly heated tubes 14 without filaments are interposed between the tubes 12. Metal casing 1 forms a reflector in which ceramic supports 2 are secured by bolts 3. The supply leads 8 have strain relieving bushings 10. Applications to heating travelling plastics sheet materials, paper webs and lacquered surfaces are mentioned, as well as heating stationary plastics films and plates prior to thermoforming in vacuum forming machines.

Abstract: 1293690 Selective printing TOKYO SHIBAURA ELECTRIC CO Ltd 22 Dec 1970 [22 Dec 1969] 60875/70 Heading B6F [Also in Division B8] In article sorting apparatus, markings, for determining the route of a baggage on a conveyer system 2 and lanes 7a-7j, are stamped on labels which are applied to the baggage 14 by an applicator 3. At station A an operator actuates key 69 thereby storing the baggage data in memory 4a. The baggage moves on a conveyer 1a-1d to a position in front of a vacuum cup 13 where it stops. The operator then actuates feed rollers 18a-18d, advancing a label strip 16, and depresses button 70 which energises magnets 33. These drive print members 24 which imprint code marks on the strip 16. Further marks are printed at a type wheel 26, the printed strip being checked by a read-out portion 21 which compares the markings to the previously stored input. Cutters 19 then sever the label, this action stopping the feed rollers 18a-18d. The label is then guided to the vacuum cup 13 which holds the label whilst a roller 47 applies adhesive thereto. The cup 13 then advances the label and attaches it to the baggage. The baggage is placed on the conveyer 2, travelling past a further read out device 9 which activates a control 8 transmitting classifying signals 10 which selectively operates gates X. In a modification, the label strip is replaced by label blanks stacked in a magazine box.

The fluid pressure controller 458 is an electrically operated air valve with a coil 484 connected to the tachogenerator through an adjustable rheostat, and a ball 494 seating, through a hole 492 in a balance beam 490, on an air nozzle 478 close it when the coil 484 moves downwardly, whereby the supply of air under pressure through inlet 462 and restriction 474 to a pressure multiplying pneumatic: hydraulic transducer 248 is controlled in correspondence will be speed of the prime mover. A rolling diaphragm 258 and a seal 272 separate a lower air chamber from an upper hydraulic chamber and the difference in diameter between the piston 268 and plunger 270 determines the ratio between the pressures. The hydraulic pressure is applied through a conduit 246 to the actuator of the rotary power absorber and the ratio between the pressures can be set by means of the rheostat. This system replaces the positive displacement fluid control system in the apparatus described in the parent Specification.
