Title: Machines for driving threaded fastening members
IPC: B23P19/06
Filed: 1972-11-11
Abstract: 1454995 Screwing-up machines RUSSELL AUTOFEED Ltd 13 Nov 1973 [11 Nov 1972] 52178/72 Heading B3N A machine for driving a thread fastener, e.g. a screw 18, into engagement with a workpiece comprises a power driven rotary screw driver 16 for drivingly engaging the screw 18, a mechanism for advancing and retracting the screw driver 16 along its axis, feed means 20 for feeding a screw 18 into the path of advancement of the screw driver, and a nozzle assembly 19, including a gripping means, for holding a screw by spring biased jaws whilst the screw driver is advanced into driving engagement therewith, and being characterized in that the said mechanism initially advances the screw driver relative to the stationary nozzle assembly to ensure that the screw driver 16 is drivingly engaged with the screw 18 before the said screw is moved into engagement with the workpiece. The screw driver is rotated by a belt driven shaft 14 through a torque slipping device 12. The shaft 14, device 12 and screwdriver 16 are carried in a housing 25 attached to a base plate 36 which is slidable on a base 38 by a pneumatic jack 39. The jack drive passes through a spring 41 to a collar 42 attached to the base plate 36 so that when movement is stopped by engagement of the screw with the workpieee continued movement of the jack engages a probe 59 with a micro-switch 60 to initiate a a return stroke. The nozzle assembly 19 is mounted on a carrier 26 for independent sliding movement controlled by a rod 30. During initial movement of the housing 25 to advance the screw driver 16 a spring 47 biases the rod 30 against a fixed machine member 51 to hold the nozzle assembly 19 stationary to allow the screw driver to engage the screw. Eventually a bush 35 engages the end of the spring at collar 48 to release the bias and allow the rod 30 and nozzle assembly to advance to the workpiece. When the screw driver is advanced into the nozzle assembly 19, and at the end of the stroke of the jack 39, an end 65 of a trip lever 62 engages behind a stop 64 to retract the nozzle assembly 19 on to the screw driver until its end protrudes from the delivery nozzle 24 to ensure ejection of a screw 18. The machine may be used to screw internally threaded parts on to bolts and studs.

Filed: 1969-10-24
Abstract: 1280668 Aerials HUGHES AIRCRAFT CO 24 Oct 1969 [28 Oct 1968] 52198/69 Heading H4A An aerial system comprises a central horn around which not less than four smaller equally sized peripheral horns are uniformly disposed, with their axes aligned towards a common point on the axis of said central horn. The number of peripheral horns is a power of two, and the total power fed to them is less than that fed to the central horn, and is substantially in anti-phase therewith. As described, a central conical horn 10 is surrounded by eight smaller conical horns 16-23. The centres of the apertures of the peripheral horns are coplanar with the aperture of the central horn, and the horns are closely packed, the diameters of the apertures of the peripheral horns being 0À618 the diameter of that of the central horn, and the ratio of the total aperture area of the peripheral horns to the aperture area of the central horn being 3 :1. The horns are mounted on a circular plate, the horn 10 being supported by a stand-off member 14 which bears against a flange 15 on its neck. The necks of the horns 16-23 are received in radial slots in the plate, and are also flanged. The horns may be fed from an input 25, Fig. 3, and a power divider 26 splits the power so that 95% goes to the central horn, and the remainder to the shunt arm of a magic tee 32, the series arm of which is terminated, and the output arms of which are connected to the shunt arms of magic tees 33, 34, the series arms of which are also terminated. The output arms of the magic tees 33, 34 are connected to the shunt arms of magic tees 35, 36, 37, 38, the series arms of which are also terminated. The output arms of the magic tees 35, 36, 37, 38 are connected to the peripheral horns 16-23. All of the inputs to the horns are designed to launch a dominant TE 11  mode, which may be "multi-moded" in the case of the horn 10. If dual orthogonal polarization is required, an orthogonal mode transducer is interposed between each horn and the feed network of Fig.3, and a similar network connected from the orthogonal mode transducers used in the orthogonal mode. Terminations can be removed from any or all of the magic tees 32-38 for the purpose of providing aerial pointing error correction information (monopulse operation). An aerial system as described is particularly suitable for installation on a synchronized satellite, since a beam giving earth coverage has a greater intensity at its edges than at its centre, the difference being, for example, 3À6 dB (Fig. 6, not shown).

Title: Chroma keying video colour signals
IPC: H04N9/75
Filed: 1974-12-04
Abstract: 1465379 Colour television systems ROBERT BOSCH GmbH 4 Dec 1974 [8 Dec 1973] 52393/74 Heading H4F The switching signal for chroma keying video colour signals when a selected colour tone occurs is produced by an arrangement including two comparators and a matrix which generates two colour difference signals from the colour signals of a given colour source, e.g. a colour camera. The comparators receive respective colour difference signals and respective corresponding reference signals representing the selected colour tone, each feeding an AND gate which delivers the switching signal. The comparators may have one or two thresholds. Fig. 1 illustrates one embodiment of the arrangement. Matrix 9 may be fed by one of the cameras 1, 1<SP>1</SP> and provides the colour difference signals. Unit 13 may include a joystick control bar coupled to the wipers of potentiometers (Figs. 2-4, not shown) such that the two reference signals depend upon the orientation and tilt of the bar. When the difference of the signals fed to a comparator 10 or 11 exceeds a certain value, or lies in a certain range of values in the case of two thresholds, it sends a signal to gate 16 which controls switch 3 to select the output of one of the cameras.

Patent GB-533426-A (GB)
Abstract: 533,426. Melamine. BRITISH INDUSTRIAL PLASTICS, Ltd., and BROOKES, A. May 11, 1939, No. 14102. [Class 2 (iii)] Melamine is prepared by fusing cyanamide and/or dicyandiamide at atmospheric pressure in the presence of a stable salt of guanidine, biguanide or derivative thereof under such conditions of time and temperature control that there is little disruption of the guanidine radicle. The salt or mixture of salts of guanidine, biguanide or derivative thereof which remains after the melamine has been separated may be used again in the process. Suitable salts are guanidine hydrochloride, sulphate and thiocyanate; biguanide hydrochloride and nitrate ; and the hydrochlorides of methyl- and phenyl-guanidines and of dimethyl-biguanide ; the carbonates are unsuitable. The salts may be initially prepared, e.g. by fusing cyanamide or dicyandiamide with an ammonium salt or substituted ammonium salt or thiourea, and the cyanamide and/or dicyandiamide added in stages. The process is effected within the temperature range of 150-250‹C. and various methods are described for controlling the temperature within this range. According to the examples, (1) dicyandiamide is .melted with ammonium chloride in an open pot, a further quantity of dicyandiamide is added and the temperature maintained at 180‹C. for 4-5 hours, yielding a mixture of melamine and guanidine hydrochloride ; (2) dicyandiamide and ammonium chloride are cautiously melted and more dicyandiamide added in portions at intervals ; after heating the melt at 180-190‹C. for 4 hours it solidifies to a mixture of a melamine and guanidine hydrochloride ; (3) on extracting the final fusion product of (1) and (2) with cold water and evaporating to dryness, guanidine hydrochloride is obtained, which is fused with dicyandiamide for 4-5 hours at 180‹C.; the mixture of melamine and guanidine hydrochloride obtained contains the latter in substantially the original quantity;. (4) dicyandiamide is fused with thiourea in an open vessel, and after adding more dicyandiamide, the melt is maintained, at 180-190‹C. for 3 hours; from the product comprising melamine and guanidine sulphocyanide, the latter is recovered by leaching with cold water and evaporating to dryness, and is fused with further dicyandiamide for 6 hours at 160-180‹C. to give a product comprising melamine and guanidine sulphocyanide; (5) dicyandiamide is fused with dimethylamine hydrochloride and maintained for 12 hours at 160-170‹C.; the product consists of melamine and dimethylguanidine hydrochloride ; (6) the mixture of guanidine and phenylated guanidine hydrochlorides obtained by fusion of triphenylguanidine hydrochloride with dicyandiamide followed by extraction with water and evaporation to dryness, is fused with dicyandiamide for 1¢ hours at 170‹C. in an open pot and after adding more dicyandiamide, the heating is continued at 180-190‹C. for 3 hours; the product comprises melamine in admixture with guanidine and phenylated guanidine hydrochlorides, which may be extracted and used in a further fusion with dicyandiamide.

Title: Improvements relating to the Balancing of Rotors.
IPC: G01M1/34
Filed: 1967-11-24
Abstract: 1,178,337. Balancing rotary bodies. GARRETT CORP. 24 Nov., 1967 [25 Nov., 1966], No. 53626/67. Heading F2U. [Also in Divisions F1 and H1] A rotary body 11, e.g. a gas turbine rotor, is balanced by rotating it in bearings 12, a component of the rotating resultant force exerted on the bearings being sensed, e.g. by transducers 16 due to movement of the bearings, and producing a signal in synchronism with rotation of the rotor to trigger a pulse of concentrated energy, e.g. from a laser or to produce a spark, directed at the rotor to remove material therefrom without exciting additional unbalanced forces on the rotor. As described, the bearings 12 are mounted in U-shaped members (14), Fig. 1 (not shown), for limited transverse movement of the rotor shaft 13 but against vertical movement, by two vertical flexplates (15), the transduceds 16 being inserted between the plates and the vertical arms of the U-shaped members whereby, when the rotating resultant unbalance force is horizontal, the bearing moves and a signal is fed to an out-ofbalance detector 26 which produces a signal of sine wave form corresponding to each rotation of the rotor. The wave is then shaped at 27 and, when the rotor is rotating rapidly, a pulse diode 28 feeds forward one pulse for each three or four rotations of the rotor to allow the laser 24 time to respond. An oscilloscope 32 displays the wave form 33 from the detector 26. After each response from the laser, if the unbalanced mass is being removed, the phase of the wave remains unchanged but its magnitude decreases. If however, the laser is removing material 180 degrees opposed to the unbalanced mass the amplitude will increase. Similarly, removal of material from any other position changes the phase of the wave. A pulse delay 29 adjustable at 34, serves to allow adjustment of the moment of firing the laser, to ensure balance correction. Again, the connection of unbalance of a gas turbine rotor may be carried out with the rotor assembled in the same housing and bearings in which it is to be ultimately assembled in the turbine. The laser beam is then directed through a window in the housing.

Abstract: 1,200,456. Valves. ENGLISH ELECTRIC CO. Ltd. 29 Nov., 1967 [30 Nov., 1966], No. 53717/66. Heading F2V. In a selector valve, communication between one of a plurality of circumferentially spaced and axially extending inlet ducts 77, each leading from a radially disposed inlet 16, and an axial duct 14, leading to a radially disposed outlet 13, is effected by means of a passage 26 formed in a rotor 20, the rotor being arranged to blank off, at any one of its positions, all but one of the inlets 77 and being arranged to be indexed between its positions by the successive application of pressure and vacuum to a port 51, such application resulting in a piston 44 and slide member 41 moving firstly to the right and then to the left, as seen in the drawing, with the consequential engagement of ratchet teeth 49 and upstanding pins 40, which engagement effects the actual indexing. The ends of duct 26 are defined by bushes 30 and 70 which are spring biased against the outlet and inlet ports 14, 77 respectively. Of these, bush 70 is formed with passages (82, Fig. 2, not shown) in its side wall, the passages opening into that end of the bush which engages housing part 10 and being in communication with a region of pressure which is lower than that in any other part of the valve and which is formed outside of the valve, the communication being established by means of duct 71, annular chamber 72, and ducts 73 and 76, and the arrangement serving to prevent any leakage between the rotor chamber 78, and a selected inlet 77. An electrical system 56, 57, 58, 60 and 61 is provided for indicating the state of the valve.
