Abstract: 875,292. Furnaces for heating pulverulent materials. STANDARD OIL CO. Oct. 14, 1958 [Oct. 22, 1957 (2)], No. 32713/58. Class 51 (2). [Also in Group XXIII] To produce hollow glass particles or spheres of a diameter of 5000 microns or less, preferably 74 to 250 microns, finely divided solid particles of glass forming material in admixture with a blowing agent are introduced in the lower part of a vertical furnace zone into a stream of hot gas passing upwardly through the zone, the temperature and velocity of the gas being adjusted so that the particles remain in the hot gas stream for a period of time to fuse the particles and liberate a gas from the blowing agent so as to form unitary hollow spheres, the expanded spheres being carried upwardly and out of the furnace by the gas stream to a cooling zone where the spheres are recovered. As shown in Figs. 1 and 3, a furnace comprises an outer jacket 10 surrounding a burner housing 38 and a cooling zone 9, through which the particles from a hopper 2 are drawn, the particles passing through a screw conveyer 5 to a surge box 6 with air conduit 7 and conduit 8 leading to the base of burner housing 38, by means of a blower 28 connected through the top of a cyclone separator 15 with a duct 13 leading to the conical top 11 of the jacket 10. The hollow particles, which are cooled to solidify the outer skin in the zone 9, are mainly carried upwardly and transported to the cyclone separator 15 and collected in receiver 34, the rest falling to the conical lower part 16 of the jacket to be collected in receiver 20. At the bottom of burner housing 38, conduit 8 is surrounded by an air conduit 41 which extends above the level of a burner 40 supplied by gas from a surrounding conduit 46, the burner 40 consisting of a plate with a plurality of jets. A plate 44 with holes 45 surrounds the burner 40 to provide updraught and prevent deposition of molten glass. Temperature measuring devices are positioned near the bottom and top of the housing 38 so that an operator can control the temperature. As shown in Fig. 6, the burner housing 54 extends the full width of the outer jacket 60 and separate burners 51 pass near the base through the outer wall at a small angle to the radial position to give a spiral action to the gases to equalize the temperature across the housing 54. The conduit 8 ends in a spray nozzle 64 in the area 65 below the burner housing 54 and is positively fed with the particles from a hopper 2 by a blower in the conduit 7. Air enters the area 65 through ports 76 controllable in size and similar ports 55 are provided in the cooling zone 53 above the housing 54 to control the temperature of the zone, the air being drawn upwardly by the blower 28. U.S.A. Specifications 2,676,892 and 2,797,201 are referred to.

Title: Improvements in or relating to hydraulic shock absorbers for vehicles
IPC: F16F9/14
Filed: 1934-11-15
Abstract: 427,294. Hydraulic shock-absorbers. LACROIX, C., 36, Rue de la Source, Brussels. Nov. 15, 1934, Nos. 32927 and 32928. Convention dates, Nov. 16, 1933 and Oct. 15, 1934. [Class 108 (iii)] In a valveless hydraulic shock-absorber of the rotary-vane type particularly for vehicles having independent wheel-suspensions, each of the variable-volume chambers is in permanent communication through constricted openings with a peripheral passage through which transfer of liquid between the chambers is effected. As shown in Figs. 2, 3, the casing 5 of the shock-absorber is divided into concentric portions 13, 14 by a circular wall 11 mounted in grooves 12 in the casing, the inner portion 14 being enclosed on opposite sides by the portion 9 of the casing and by a disc 15, and centrally by a sleeve 16 mounted on the supporting shaft 3. The portions 13, 14 are in permanent communication by means of holes 24 in the wall 11 through which, on relative angular movement of the blades 19, 20 oil &c. is sucked into and ejected from the various chambers inside the portion 14 to damp the blade movements. Fluid-tightness of the inner chamber is ensured by welding one end of the sleeve 16 to the portion 9 of the casing, by means of the joint between the other end of the sleeve and the disc 15 and a washer 18 engaging the sleeve, and, if required, by packing at the latter end of the sleeve. The blades 19, 20, each secured to one of a pair of arms 1, 2 pivoted at their outer ends 6, 7 to the vehicle frame and axle, are cut-away so that each pair of blades encloses the hub 19<1>, 20<1> of the other pair. In a modified construction a single central arm and a double arm enclosing twin coupled casings 5 are provided. In a further construction, Figs. 7, 8, the concentric portions 13, 14 communicate through holes 24, grooves 39, and holes 38 provided respectively in a rotating bellshaped member 28 and in an angle-ring 29 screwed into a cup-member 27 forming the casing. The blades 19 are secured to the bell 28 which has a non-circular boss engaging an opening in the arm 1, and the blades 20 are secured to the cup-member 27 which is fixed to or formed integral with the arm 2. Fluid tightness is ensured by packing 32-36. A ball-bearing may be inserted between the shoulder 31 of the bell 28 and the nut 30 which locks the angle-member 29 in position. The arm 2 may be bent to form a fastening lug for securing the shock-absorber at rightangles to the vehicle frame.

Title: Improvements in or relating to automatic telephone systems

Abstract: 656,118. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Dec. 22, 1948, No. 33047. Convention date, Jan. 9. [Class 40 (iv)] In an inter-exchange system employing registers, any of the digital impulse trains may be extended by n impulses, n being not less than 10, to convey additional information to the terminating exchange, e.g. that the call is a long distance one. In a mixed-digit system, the last digit may be extended in this way to indicate the end of impulsing, and it may be further extended by n more impulses to indicate a long distance call. In a registersender, Fig. 2, the registers V1-3 are set from an operator's keyboard and impulsing is started when key TS is pressed. If the call is a long distance one, key TJ is also pressed. Impulses generated by self-interrupting relay R1 go to the outgoing circuit over t and to the magnet of sending switch V10, and R3 operates momentarily while V10 is in its normal position to advance sequence switch S to position 1. Relay R2 energizes when V10 comes into alignment with the first register VI, stops impulsing and advances V10 to normal. Relay R3 re-operates and through R4 releases R2 to start the sending of the next digit, S being advanced to position 2 to connect up V2 when R3 falls back. With key TJ unoperated, sequence switch S when moved from position 2 goes immediately to position 4 to connect up V3, and the third digit is sent in the same way as the first two. With key TJ operated, however, the circuit for moving S out of position 3 is opened by R5, and V10 has to pass through its normal position again in order to operate R3 momentarily and thus advance S to position 4 to connect up V3 ; 11 impulses are therefore added to the third digit. If V3 is connected instead to position 5, 11 impulses will always be added to the third digit to indicate that it is the last, and a further 11 impulses will be added if key TJ is operated. At the terminating exchange, the register D3, Fig. 3, that takes the third digit operates relays R13, R14 on successive passages through its normal position, thus closing alternative circuits 141, 142. The switch V10 may be replaced by a relay chain.

A logic circuit includes a transistor amplifier to the base of which the logic signal is applied via a Zener diode biased to add a constant voltage to the signal, the emitter being connected to earth or other reference point through a diode (or further transistor) and a Zener diode biased similarly to the first. In Fig. 1, two AND gates D1-D4 are connected to an OR gate D5, D6 to control the state of transistor T so that the output F is the inverse of (A.B + C.D). When T conducts, current flows through R5, and when T is cut-off the current through R4 passes through diode D and Zener diode Z2. The output voltage change is limited in one sense by D7 and D11, and in the other sense by D9 and D12. In Fig. 2 (not shown), the diode D is replaced by a second transistor emitter-coupled to the first to provide a second output which is the inverse of the first, i.e. represents (A.B + C.D).
