Title: Radio navigation systems
IPC: G01S13/78
Filed: 1961-02-10
Abstract: 964,204. Radio navigation. STANDARD TELEPHONES & CABLES Ltd. Feb. 10, 1961 [Feb. 12, 1960], No. 5047/61. Drawings to Specification. Heading H4D. Relates to a radio beacon system, e.g.Tacan, comprising a beacon which transmits (1) a directional radiation pattern rotating at 15 c/s., and (2) an omnidirectional reference signal when a datum axis of the directional pattern is directed in a datum direction and which transmits coded reply signals in response to corresponding coded interrogation signals from an aircraft which is provided with equipment for determining its distance d and bearing from the beacon. According to the present invention the aircraft transmits a differently coded bearing reply signal when the datum direction of the beacon directional pattern is directed at the aircraft and said bearing reply signals are received at the beacon and applied to brighten the radial trace on a C.R.T. which is rotated synchronously with the directional pattern to indicate at the beacon the direction of the aircraft. The transmission of each bearing reply signal from the aircraft is delayed by a time period (T-2 d/o) where T is constant, e.g. four m/secs., so that the bearing reply signals are received at the beacon with a constant delay T relative to those signals transmitted from the beacon which initiate the bearing reply signals, the constant delay T being independent of the distance d of the responding aircraft. At the beacon receiver the rotation of the C.R.T. trace is delayed by the amount T relative to the rotation of the directional pattern so that the indication produced is that of the bearing of the aircraft at the time that the datum direction of the beacon directional pattern is directed at the aircraft. The coded interrogation and reply signals for distance measurement may comprise double pulses with a 12 Á-sec. spacing and the bearing reply signals may comprise double pulses (18 Á-sec. spacing) or triple pulses (12 Á-sec. spacing). The two sets of coded signals produced at the aircraft may be generated by a single coder. Fig. 1 (not shown), the input interrogation trigger pulses applied thereto being suppressed three times a second to allow production of the coded bearing reply signals. Alternatively, Fig. 2 (not shown), when the datum direction of the rotating directional pattern is directed at the aircraft, the aircraft equipment generates a 250 Á-sec. gating pulse and the bearing reply signal is initiated by the trigger pulse coincident with said gating pulse.

Abstract: 510.688. Making multiply tubes; angular bending; forging; brazing. GENERAL MOTORS CORPORATION. Oct. 29, 1937, No. 29607. Void. Convention date, Nov. 5, 1936. [Classes 83 (ii) and 83 (iv)] In apparatus and process for the continuous production of multiply tubes from a plurality of strips of steel brazed at the joint overlapped strips 40, 42, Fig. 5, are fed to rolling apparatus 60 thence through a swaging apparatus 48 to a heating chamber 200 with brazing means 204 and finally after excess of copper is removed the tube passes to a cooling apparatus 320. The overlapped strips may be coated with oil capable of cracking and fed from a supply 75 to a pad 73. A spot welder 171 fixes the overlapped strips together to prevent relative displacement during the tube forming. A non- oxidising atmosphere is provided during the heating and brazing and gases pass in through a pipe 216 and a blower access to the tube being obtained by perforations in an outlet tube 202 through which the work passes. An outlet pipe 210 is also perforated for the gases which may consist of 14 per cent. H2, 11 per cent. CO, 4 per cent. CO2 and the remainder N2, such gases may result from cracking a natural gas. The lubricant added at 75 is chosen to provide protective gas by cracking in the heat of the furnace. The Specification describes and illustrates the apparatus for bending the strips into tubes by means of profiled rolls and formers.

Abstract: 1292326 Collagen CENTRE TECHNIQUE DU CUIR SA 17 Oct 1969 [27 Nov 1968] 51075/69 Heading C3H [Also in Division B1] A method for the preparation of a dispersion of collagen (i.e. a normal or colloidal solution or gel) which may be air-free or aerated, comprises preparing a suspension of collagen fibres in water or in an organic medium, creating a subatmospheric pressure in a treatment chamber of a dispersion apparatus having stirring means, the suspension being introduced into the treatment chamber by means of the pressure difference between the sub-atmospheric pressure created and atmospheric pressure, maintaining the sub-atmospheric pressure or providing a different pressure within the treatment chamber, and transforming the suspension into a dispersion by stirring and controlled acidification by means of a mineral or organic acid. If the transformation is effected under sub-atmospheric pressure, a substantially air-free dispersion is obtained, if it is effected under super-atmospheric pressure, an aerated dispersion is obtained. The examples describe the preparation of air-free or aerated dispersions from collagen fibres derived from cowhide. In Fig. 2, which shows a reactor suitable for effecting the above method, sub-atmospheric pressure is created in chamber 1 by applying a vacuum through tube 15, collagen fibre suspension and acid are introduced through tube 14, and pressurized air, if required, is supplied through tube 16. Stirrer 7 is rotated by electric motor 12. Cover 4 is clamped to reactor 1 by device 6.

A cross-slide 6 is mounted on a saddle 7 and carries a tool clamping member 5 for a cutting tool 1 and between the member 5 and cross-slide 6 there is located a slider unit 2 which incorporates a crossshaped member 12 interposed between upper and lower parts 42, 40 respectively which permits adjustment of the tool clamping member in two directions at right angles relative to the cross-slide on the lathe bed, the cross-member being displaceable by independently actuated screw members 10, 10<SP>1</SP>. In operation, respective tools are presented to the feeler 4 and which is displaced thereby from a predetermined zero position in either or both of the two directions. The displacement of the feeler actuates the control unit which transmits signals to a control member 33 which causes actuation of the screw members 10<SP>1</SP>, 10, which restores the cutting edge of the tool to its correct position with the feeler in its zero position. This control is independent of the numerical control of the machine tool. The feeler is provided with plain sides and is preferably of rectangular crosssection, the sides of the feeler corresponding to the planes of movement of the slider unit. One or more feelers may be provided for use with respective ones of tools mounted on the crossslide.

Abstract: 1287635 Treating sheet glass PERMAGLASS Inc 12 Nov 1969 [8 Jan 1969] 55298/69 Heading C1M Apparatus 10 for treating sheet glass comprises a furnace 12, cooling means 14 and an intermediate treatment station 16, a conveyer means 20 being provided to move the glass sheets within the furnace, and the cooling means and the intermediate station 16 including a device 34 having passages leading to its surface for supplying a vacuum thereto which serves to hold a glass sheet against the said surface while the glass is being treated, the device 34 being movable between the heating and cooling means. Preferably the treatment includes a bending step in which case the device 34 is in the form of a mould. The mould is movable vertically towards and away from the conveying means by a fluid actuator 64, and movable horizontally by means of a chain 58 driven by sprockets 56. The conveying means may comprise an endless metal belt 20 passing through the heating and cooling means and having openings through which the gases of a support bed 18 in the heating means, may pass. In use a sheet of glass is placed on the conveyer 20, heated to its deformation temperature, after which it is supported on gases above the conveyer. The mould 34 then contacts the glass sheet and supports it by vacuum to transport the sheet to the cooling means while causing the sheet to conform to the curvature of the mould. The mould may be convex or concave. The glass is cooled by a blasthead 14 in the cooling means and then returned to the conveyer 20 for additional cooling. In a modification suitable for very large sheets of glass (Fig. 4, not shown) the conveyer extends only through the heating means, the sheet of glass being transported by the mould and placed on a ring frame and moved into the cooling medium by the frame, which may oscillate during cooling.
