[Class 4] A flying-boat is provided with hydrovanes and with means whereby the angle of incidence of the hydrovanes and of the wings and the line of thrust of the air-screws may be simultaneously adjusted. Biplane wings are mounted on axles A, which meet in the midplane of the hull and are joined by couplings C provided with chain sprockets. Three sets of hydrovanes E of which the centre set is shown in Fig. 1 are similarly arranged and axles A<1> of the hydrovanes are coupled together for similar movement. The three couplings C are connected by chains B and may be angularly adjusted by operation of a motor P. Engines are mounted to tilt with the wings, but additional engines driving pusher and tractor airscrews may be mounted above the hull. The wing axles are journalled in the hull structure at J, in combined thrust and journal bearings J<1> in the walls of the hull, and in outboard bearings G, the housings of which are connected by bracing wires W. Bearings J<1> include stops for limiting tilting movement and means for locking the axles in adjusted position.

Title: Improvements in or relating to screw clamping means for shuttering used in concrete wall building and the like
IPC: E04G17/12
Filed: 1939-02-25
Abstract: 520.812. Screwed strainers. VIGIER, W. DE, and LANDAUER, W. Feb. 25, 1939, No. 6297. [Class 45] [Also in Group XXV] In clamping means such as for concrete shutters and involving right and left handed screws, the screws are made readily separable by employing a disconnectable coupling. As shown, a screw 1 has a head 2 and another a socket 3 which is provided with a recess for the head and with an internal thread for engagement by the screwed exterior of a member 5. The latter which has wings 7 for adjusting it, is movable on the shank of the screw 1. A pin 8 may be used to attach the socket 3 to the screw 4 and thus may be riveted over. Welding may be employed for this purpose. In a modification shown in Fig. 2, the screws are connected by the two halves 9 of a coupling, a pin 10 passing therethrough and being secured by a split pin 11. Other modifications are described which, are disconnectable with the aid of a pin, which can be readily withdrawn..

Title: Transportation systems
IPC: B61L3/00
Filed: 1972-02-10
Abstract: 1401803 Vehicle control system DEFENCE SECRETARY OF STATE FOR 8 Feb 1973 [10 Feb 1972] 6382/72 Heading B7H In a transportation system for vehicles movable at synchronous speeds over a plurality of first and second main tracks which cross over at different levels and in which the progress of the vehicles on the tracks, e.g. first main track T1 and second main track T2 is controlled by signalling arrangements including transmitters TX1, TX2, respectively, and signalling loops S1 S2, respectively; each track intersection or cross over includes a pair of junction tracks between the main tracks on each of which, e.g. the only one shown T12, progress is controlled by a separate signalling arrangement including transmitter TX12 and signalling loop S12 and a computer C12 is provided for controlling of queueing of vehicles on the junction track and the exit of vehicles from the junction track to main track T2. The transmitters TX1, TX2 and TX12 and detector units D1-D5 are connected to the computer C12, the latter units being used for detecting vehicle presence, identification and address and also for transmitting signals to the vehicle. The progress of the vehicles is controlled by apparatus as described in Specification 1,335,985 by comparing slot increment command pulses from the loop with pulses generated on the vehicle as it passed slot markers or cross overs in the loop. The compression is used to derive a position lag signal which is used to define a slot moving in advance of the vehicle in which the vehicle can be brought to a halt. When the computer receives an indication from detector D1 of the presence and destination of a vehicle at position P1 it consults a priority table for that destination and if the priority number is greater than q, the number of vehicles queueing on the junction track and if q is less than Q - the number of vehicle queueing positions or slots then either via the detector D1 or the transmitter TX1 the vehicle, which is of the type described in Specification 1,352,246 receives a turning signal and engages its left guide wheel with a guide on the left of the track to route the vehicle into the junction track. If the priority number is less than q then the vehicle is not diverted and carries on on the first main track to the next intersection where it may be diverted. In the junction track the vehicle is controlled by signals in loop S12 from transmitter TX12, the computer causing the necessary signals to be sent to stop the vehicle at the end of the queue. The vehicle at the head of the queue PS receives its leave signal when the computer determines in response to signal received from detector D5 on the second main track that a slot is available to receive the vehicle. By the time the vehicle reaches position P6 its speed has been increased to the synchronous speed of the vehicles travelling on the second main track. In a similar manner under the control of computer CP vehicles are directed from a main track T1 to a station track TP and vehicles leaving the station are advanced into empty slots in the main track traffic.

Abstract: 594,151. Gramophone pick-ups. DECCA RECORD CO., Ltd., and O'.BRIEN, W. J. March 14, 1945, No. 6438. [Class 40 (iv)] In an electric pick-up, a potential is generated in a fixed coil or coils by oscillations of a permanent magnet mounted on the body part by means of trunnions formed integrally with the magnet. The permanent magnet 22 is pivoted about its longitudinal axis carries the stylus 24 and spring 23 and is mounted in a channel formed by the sides of coils 11, 12 and the front face 21 of a web 10 projecting from the main frame 1 of the pick-up. The magnet 22 is formed from finely divided permanent magnetic material bonded by compression or sintering or suspended within a rigid bonding material such as bakelite. The magnet is provided with trunnions 25, 26 and with sleeves 27, 28 of rubber or like resilient material which fit in bores 32, 31, the former being cut away. The magnetic axis of the magnet is parallel to the common axis of the coils which are held by a iron magnetic rivet 14. The main frame 1 of the pick-up is made of light-weight insulating material such as bakelite. In a modification, Figs. 10 and 11, the sleeves 59, 60 fitted to the trunnion of a magnet 56 fit in transverse slots 61, 62 cut in arms 63, 64 formed by a recess 55 cut in the web projecting from the main frame. The coils 77, 78 are wound on forwardly extending arm portions of L-shaped pole pieces 71, 72, the upright arms of which are spanned by a bar of soft iron 81 to complete the magnetic circuit. The bar 81 may itself be a permanent magnet. The pole pieces 71, 72 are clamped by non- magnetic rivets or screws and U-shaped spacers 66, 67 between the pole pieces and the arms 63, 64 hold the sleeves 59, 60 in the slots 61, 62. The Provisional Specification states that the trunnion of the magnet may be of square section and that the cores may be of sheet metal. The upright portion of the cores may be flanged and bridged by a horse-shoe magnet.

The assembly is driven by a reversable electric motor 10 which, when rotated in one direction, acts through a first one-way clutch 18, a worm gear 38, a worm wheel 40, an eccentric pin 44, and a slot 52 in an arm 50 to reciprocate a rod 48 which is connected by flexible cables 76, 76' to the arms 82 of the head-lamp wipers. The reciprocating motion of the rod 48 acts to pivot the arms 82 from their inoperative to operative positions. When the arm 82 is in its operative position, as shown, the motor 10 is reversed and drives through gears 14, 16, a second one-way clutch 20, gears 68, 70, 70' and flexible shafts 78, 78', worm gears 98 which mesh worm wheels 94 fast with the wiper blades 84 to rotate the latter about the ends of the arms 82 and thus clean the head-lamp lenses 80.
