Abstract: 302,630. Davies, J. P. Sept. 17, 1927. Aerostats; propelling. -Aircraft, particularly airships, are provided with an air conduit or conduits pa s s i n g through or around the envelope and fitted with openings and valves the adjustment of which controls the points of ingress and egress and the direction of flow of an air current induced in the conduit by power means so that the current can be directed upwardly, downwardly, forwardly, or rearwardly for propelling and steering the aircraft. Fig. 2 shows a longitudinal section of an airship having a conduit b arranged in a central longitudinal plane within the envelope. The conduit has valves for closing openings b<3> - - b<6> or alternatively obstructing the flow through the conduit, and at the forward end an opening b is controlled by a valve c on a transverse axis. A chamber i is formed at the rear end communicating with the conduit by the openings b<4>, b<5> and by an opening in which is arranged a propeller d. An opening b<7> in the chamber i is controlled by valve i<1> or a vertical axis. With the valves arranged as shown air enters at b' passes into the chamber i and back into the conduit through the opening b<5> and out at the opening b<6>. The valves c and i<1> act respectively as elevator and rudder in addition to external control surfaces provided. Fig. 4 shows a balloon in which a conduit b communicates with a central hollow shaft o by openings o<1>, o<2> controlled by valves q, p, a propeller d being arranged in the shaft o. Manoeuvring valves r, r<1> are provided to direct the air current on to surfaces s, s<1> moving about vertical and transverse axes respectively. Fig. 7 shows a cross-section of an aeroplane having a central cylindrical shaft v with a propeller d and with valves 1, 2 at its upper and lower ends. The shaft v communicates with passages v<1>, v<2>, v<3> controlled by valves 4, 3 respectively. According to the Provisional Specification the air conduits may be fitted with reversible propellers. Balancing automatically.-A propeller z driven through a clutch z<1> acts as a gyroscopic stabilizer. Anchoring; shock-absorbers, applications of.- An inflated tube j, Figs. 2, 4, acts to absorb shock on landing and by forming an airtight joint with the ground co-operates with the air current controls to produce a vacuum within the area enclosed by the tube to hold the airship or balloon on the ground. Alternatively the tube may be adapted to be filled with water when the airship is floating on water.

Abstract: 875,128. Heat treating metal articles. HOBDELL, A. C. July 31, 1958 [Aug. 2, 1957], No. 24553/57. Class 72 Automatic apparatus for heat treating metal articles comprises a conveyer, having holders for the articles, operated intermittently to convey the articles by steps from a loading station through a heating device, to a hardening station and clamping means at the hardening station to hold the articles in a desired shape during hardening. As shown, applied to the heat treatment of knife blades, holders 12, carrying tubes 15 to receive the tang of a blade, are mounted on a conveyer 13 which is moved by a piston and cylinder arrangement 27, 26 to bring each holder successively into each of the working positions i.e. loading, heating and hardening. Between heating and hardening the blades pass a device for orienting them comprising an adjustable finger 47 (Fig. 5) which moves the blades so that they are aligned with the clamping device which comprises a fixed block 56 and a moving block 55 mounted on a plunger 59 for each blade, the moving blocks being resiliently mounted so that they may adjust them-- selves to the taper of the blades before the full clamping pressure is applied. The blocks are all water cooled and cooling air may be applied to the bolsters of the blades. The clamping and movement of the conveyer may be performed by pneumatic means. Specification 813,788 is referred to.

Title: Controllable electrochromic display cell
IPC: G02F1/1523
Filed: 1975-06-10
Abstract: 1502340 Controlling light BBC BROWN BOVERI & CO Ltd. 10 June 1975 [12 June 1974] 24889/75 Heading G2F A display cell comprises in order an electrode 2, an electrochromic layer 3 responsive to the flow of ions, a layer 5 insulating to electron flow but being ion conductive, and non-polarizable electrode layer 6 in direct contact with layer 5. At least one of electrode 2 and layer 6 is transparent, and at least one is disposed on a substrate 1. The layer 3 may be of a transition metal oxide, particularly WO3, MoO3 or mixtures thereof which form blue bronze upon electrolytic reduction with incidence of ions from the layer 5, e.g. AgxWO3 where O<x#0À3. The layer 5 preferably has a specific conductivity between 10<-1> and 10<-10> ohm<-1> cm<-1> with a thickness of 30Á or less. It may be crystalline, e.g. AgI, LiCl, CuBr, CuI, Rb4 AgI5; or a Li- Si-B oxide glass; or a polymer e.g. a perfluorinated sulphonic acid. The layer 6 may be a mixed electron-ion conductor, for example a turgster and/ or molybdenum bronze which may also be electrochromic; or hydrogen bearing Pt or Pd; or a graphite-alkali metal alloy; or a sulphide or selenide of Ag or W. The layer 5 may provide contrast between coloured and bleached areas of layer 3. Alternatively the layer 6 may fulfil this fuction (e.g. if of Lix WO3, where 0.7#x#0.85) if the layer 5 is transparent. As shown, the electrode 2 is of transparent ten oxide on a glass substrate 1, and a layer of gold is deposited over the layer 6. It is said that by using an ion conducting layer 5, which layer is required to prevent shorting of the electrodes, a thicker and less patchy layer with lower generating voltage may be provided than is possible with an electron transporting layer e.g. of SiO. A non-polarizable electrode 6 prevents deposits in the cell e.g. metals at the junction between the cathode and the layer 5.

Abstract: 1304022 Tunnel diode monostable circuits INTERNATIONAL BUSINESS MACHINES CORP 26 May 1970 [2 June 1969] 25119/70 Heading H3T A monostable circuit suitable for limiting its output pulse frequency to a given value if the input pulse frequency rises above the given value comprises a tunnel diode latch CR1 feeding its output back through a long-tail-pair switch 10 and a delay circuit 13 to restore the state of the latch after triggering by an input pulse and to inhibit further triggering until the restoration. A positive pulse edge at the input produces at the output of a short-circuited delay line D1 a positive spike which switches the tunnel diode to its high voltage state. This reverses the state of a long tail pair Q1, Q4 producing an output spike from Q3 while C5 charges and also a pulse at the input of the delay circuit 13. The resulting delayed output pulse causes transistor Q5 to restore the diode to its low voltage state. This restores the long tail pair to its original state and after the delay the input circuit is restored to its original bias. The feedback inhibits further triggering until the bias is thus restored so that input pulses during the triggered period are ineffective. Accordingly the output frequency is limited. Diode CD1 removes negative spikes to prevent restoration of the tunnel diode at the negative going edge of input pulses. In Fig. 5, not shown, the switching transistor Q5 is omitted from the feedback path.
