Title: Air cushion vehicle
IPC: B60V1/00
Filed: 1967-08-02
Abstract: 1,148,414. Air-cushion vehicles. GENERAL DYNAMICS CORP. 2 Aug., 1967 [24 Aug., 1966], No. 35480/67. Heading B7K. A vehicle, at least partly supported by an air-cushion, comprises an air-cushion space, a power driven rotor 16 or 18 with its axis along one edge of the cushion forming a passage 12 or 14 between itself and the inside surface of the air-cushion space, there being means (e.g. a motor 24 and compressor 22) to supply compressed air through the passage to form a curtain-forming jet, the rotor being rotated to produce vortex which assists in feeding and maintaining the cushion. The rotors 16, 18 project below the body 10 of the vehicle. There may be a flap 42 co-operating with the rotor to prevent re-circulation of cushion air. The vehicle may have two parallel rotors 16, 18, which define the cushion with a pair of straight skirts 36, the size of the lifting jets being controlled by flaps 30 (in conduits 26), 40a and 40b. The rotors may be retractable and may comprise inflatable rollers having bristles or corrugations on their perimeters and having internally either discs connected to a through rigid axle, or spiral reinforcing to transmit torque to the rollers. The rotors may act as ground-engaging wheels when the air cushion is collapsed, and may also incorporate road wheels, a single wheel rotor being steerable. The body 10 of the vehicle may be shaped as a boat hull to enhance operation on water, or may have a pair of floats (59), Fig. 5 (not shown) beside the skirts 36. The upper surface of the vehicle may be of aerofoil shape to assist the air cushions to support the vehicle weight, when the vehicle is moving rapidly.

Title: Improvements in or relating to looms for weaving tufted fabrics
IPC: D03D39/02
Filed: 1929-11-21
Abstract: 342,421. Pile-fabric looms. MORTON, J., Craigiehall, Cramond Bridge, West Lothian, and OLDROYD, F. H., 72, Duckworth Terrace, Bradford, Yorkshire. Nov. 21, 1929, No. 35597. [Class 142 (ii).] Forming tufts around warps.-In looms for weaving tufted fabrics such as Oriental carpets, the tufts are introduced to a web of warps by means of a pair of gripper arms 10 mounted side by side on a shaft 18, which is moved bodily to carry the arms 10 backwards and forwards towards the fell of the fabric and is oscillated to move the arms 10 between tuft seizing and tuft releasing positions, means being also provided whereby the grippers may be independently shogged during the operation of inserting a tuft. Each gripper arm 10 with boss 19 is attached to a separate key 20 fitting into a keyway in the shaft 18, so that the movement of a key 20 by cam means (not shown) gives a shogging movement to the respective gripper arm, whilst an oscillatory movement is conveyed to the arms by rotation of the shaft 18. A ring lever 22 pivoted at 23 to the boss 19 is operated by means of a cam 31 rotatably mounted on the boss 19 and controlled from the shaft 37, the swinging movement thus imparted causing a withdrawal of the hook 21a within the arm 10 to grip a tuft. The shaft 13 is mounted on two arms 17 of a slide 12 adapted to be moved across the loom to allow a number of tufts to be tied in quick succession, whilst the slide 12 is supported by a slide 11, which is given a back and forward movement through levers 15, 14 from cam mechanism (not shown). Specifications 264,578, [Class 142 (ii), Looms, Kinds &c.], 323,260, [Class 142 (iv), Woven fabrics &c.], and 342,005, [Group VIII], are referred to.

Title: Shroud assembly for gas turbine engines
IPC: F02C7/04
Filed: 1957-11-15
Abstract: 822,124. Jet-propulsion plant. AVERY, B. A., and KEAST, F. H. Nov. 15, 1957 [Feb. 4, 1957], No. 35669/57. Class 110 (3). [Also in Group XXXIII] A gas-turbine engine shroud assembly comprises a first shroud 17 surrounding at least a part of the forward portion of the engine to define a first space 20 between the engine and the shroud, a second shroud 23 surrounding the entire engine including the first shroud defining a second space 26 between the second shroud and the first shroud and engine, a third shroud 32 surrounding the second shroud to define a third space 35 and a duct 38 joining the first space 20 and the third space 35. The size of the aircraft air inlet 25 is designed to pass the volume of air required by the engine at take off and low flight speeds at altitude. At supersonic speeds, the intake passes more air than the engine requires. To reduce the drag caused by this excess air spilling over the intake, the shroud 17 is spaced from the edge 21 of the engine inlet 10 and the forward edge 25 of the shroud 23 is spaced forwardly of the inlet edge of the shroud 17. Segmental flaps 31 are provided to control the air flow to space 26. The excess air entering the inlet 22 passes through the space 20 containing the fuel lines and controls and a duct 38 to the space 35 which discharges to atmosphere. This air is unheated. A further portion passes the control flaps 31 and is heated in passing over the engine before being discharged to atmosphere around the main jet stream. Certain portions of the shrouds may be formed by the nacelle skins.

Heading B7L. A rail vehicle incorporates a chassis 1, Figs. 1 and 2, which may be formed as part of the frame of a transformer of the type used in mines, axles 2A, 2B, attached to the chassis, one axle at least being non-rotatable, and two wheels 3 on each axle, each of the wheels on the non-rotatable axle being rotatable about a bearing block 4, Fig. 2, formed with a hole of rectangular cross-section, the hole being penetrated by a journal portion 5 of the axle also of rectangular cross-section, the vertical clearance between the block 4 and the portion 5 being constant throughout and the horizontal clearance between the block and portion varying linearly from a maximum dimension at each end 6 of the block to a minimum dimension at the centre 7 of the block. The axle at each end has a series of holes 10 for receiving a looking pin 9 of a clamp 8 at each end of the block 4, whereby the wheel track may be varied to suit different rail gauges. The wheel 3 can thus swing on the axle end about a vertical axis to allow the wheel flange to remain substantially tangential to a curved rail and thus avoid derailment. As shown, the axle 2A is pivoted to the chassis 1 about a horizontal pivot 12, offset vertically from the axis of the wheels 3. In the construction shown in Fig. 1, the bearing points of the wheels of the axle 2B and the pivot 12 provide a three-point suspension whereby all four wheels remain in contact with an irregular track.

Patent GB-807689-A (GB)
Title: Process of producing asparagine
Filed: 1956-11-27
Abstract: Asparagine is obtained from potato starch waste water by concentrating it to a solids content of at least 15 per cent (e.g. 15-30 per cent), adding a tannin or an alkali lignin to precipitate impurities (preferably at pH 5-7), separating the precipitate, concentrating the remaining liquid until supersaturated with respect to asparagine at the crystallizing temperature (e.g. to a solids content of 40-70 per cent, or preferably 55-70 per cent), and crystallizing asparagine at a temperature between 30 DEG  C. and the freezing point.  The crystallization temperature is preferably below 10 DEG  C. and is desirably around 0 DEG  C.  The product may be further purified by mixing with water and heating to 50 DEG  C. in the presence of carbon. The tannin used as precipitant may be natural or synthetic, and the former may be used as an impure extract.  The alkali lignin is the material obtained by alkali extraction of lignin-cellulose compositions, and may be used as such or in the free acid form. An example is given of the process.

Title: Device for forming fluid pulses
IPC: F15C1/14
Filed: 1964-09-04
Abstract: 1,014,330. Regulating fluid flow. SPERRY RAND CORPORATION. Sept. 4, 1964 [Sept. 16, 1963], No. 36291/64. Heading G3H. A fluid pulse former comprises a fluid amplifier having outlet passages 16, 18 leading from an interaction chamber 14, a flow divider being located in the chamber and having an edge offset from the centre line. In the embodiment shown, a power jet supplied to nozzle 12 will cause flow through the outlet passage 16 in the absence of signals to control nozzles 22, 24. The control nozzles are supplied with a pressure signal through passage 26 which has a stream divider 28 whereby flow passes through a conduit 30 to nozzle 22 and through a sliding trombone conduit 34 to the nozzle 24. In operation, when a signal is supplied to passage 26, flow from the nozzle 22 deflects the jet to outlet passage 18 until the signal passes through the conduit 34 to nozzle 24 when the jet is deflected back to passage 16. The time of the pulse out of passage 18 depends on the difference in length between the conduits. To provide a further pulse, the input signal must first be stopped. In a modification, the input signal feeds the power jet nozzle and a branch passage of longer length feeds a control nozzle thus when the signal is first applied, the jet passes through an output passage to provide the pulse until deflected by flow through the branch passage to the control nozzle.

Title: Improvements in and relating to the preparation of boron trihalides
IPC: C01B35/06
Filed: 1961-10-10
Abstract: A boron trihalide, with or without a dihaloborine, is prepared by reacting an oxygen-containing boron compound and a hydrogen halide in the presence of free or combined carbon. The reaction may be performed at 900-1400 DEG  C., with residence times 0.01-60 sec. and hydrogen halide pressures 1-10 atmospheres.  Subatmospheric pressure is also referred to. The boron compound may be boric oxide, metal or alkyl borate, or trihaloboroxine (B3O3Cl3), and hydrogen halides are HCl, HBr and Hl.  The carbon may be mixed with the boron compound, in the proportion of at least one atom of carbon per atom of oxygen in the compound, but when an alkyl borate is used, may be the carbon in the alkyl group itself. The product gases containing boron trihalide with or without dihaloborine, hydrogen, carbon monoxide and excess hydrogen halide are cooled to 300 DEG  C. in one sec. or less and may be separated by fractional distillation, absorption or adsorption, or, when hydrogen chloride is used, fractional condensation in three traps cooled respectively to -78 DEG  C., -120 DEG  C. and - 196 DEG C.  The first trap contains BCl3 and some BHCl2, the second BCl3 and BHCl2, and the third HCl.  Mixtures of BCl3 and BHCl2 may be refluxed in a fractionating column to produce BCl3 and B2H6 from the BHCl2. The trihaloboroxine may be prepared by preliminary reaction of BCl3 and B2O3 at 250-500 DEG C.

Title: Improvements in or relating to telecommunication systems
IPC: H04Q11/04
Filed: 1963-09-18
Abstract: 1,026,416. Automatic exchange systems. SIEMENS & HALSKE A.G. Sept. 18, 1963 [Sept. 19, 1962], No. 36683/63. Heading H4K. In a time division multiplex exchange system, control means are provided for successively scanning the line circuits of every subscriber in the system in order to detect the open or closed loop condition of the lines whereby if during one scan an open-loop condition of a subscriber previously involved in a connection is detected, this condition is stored in the control means so that the connection may be released if another signal indicative of the open-loop condition is received during the next scan. The system described is of the type in which the addresses of a calling and a called subscriber are stored in respective synchronously rotating memories, the outputs of the memories operating speech switches pertaining to these subscribers during the time slot allotted to the connection. During each complete cycle of time slots, the address of one subscriber in the system is provided at the output of a stepping circuit. If this address coincides with an address in one of the rotating memories a comparator circuit " informs " the control circuit of the time slot in use by the address and at the same time the corresponding line circuit is interrogated to provide the control circuit with a signal indicative of the loop condition of the line and in the event of an open-loop signal this condition is stored in a rotating memory in the control circuit during this time slot. If an open-loop signal appears when this address is next provided by the stepping circuit (indicating that the original open-loop signal was not fortuitous) the combination of the stored signal and the new signal provides a disconnection signal for the system. If a closed-loop signal appears the previously stored signal is removed from the control circuit memory. Provisions are made for preventing premature release of a connection in the course of being set up, i.e. whilst the calling party is dialling into a register or whilst the address of the called party is in the calledparty rotating memory but before he has answered the call. In the last case an additional rotating memory in the control circuit provides an inhibit signal to the control system during the relevant time slot for as long as the called party is being rung. A somewhat simpler system which provides for only calling-party release is described and facilities for forced release are also mentioned.
