Title: The formation of packets of particulate substance
IPC: B65B47/10
Filed: 1961-09-28
Abstract: 989,350. Packaging. PROCTER & GAMBLE Ltd. Sept. 28, 1961 [Sept. 28, 1960], No. 34983/61. Heading B8C. A process of forming packets of particulate material comprises deforming a first film strip so as to form a pocket therein, forming a small puncture through the wall of the pocket, placing the material in the pocket, placing a second film strip over the first film strip so that the material in the pocket is enclosed between the two film strips, sealing the film strips together to form a packet, and withdrawing air from the packet through the puncture. A web 7 of heated thermoplastic film, e.g. a water soluble polyvinyl alcoholic film, is fed on to a drum 1 and drawn into recesses 11 by suction applied to ports 8, 9, 10. A hole is then made in the base of the pocket, either by a rotating spider 13 which has spikes 12 which are pushed through the film above each of the ports 9 or by spikes (Fig. 3, not shown) one of which extends upwardly through the centre of each of the ports 9. The pockets are then filled, e.g. with detergent, and a second web led over and heat sealed to close the pockets, excess air enclosed in the pack being withdrawn through the hole. The drum 1 has the recesses 11 mounted in pairs side by side so that two rows of pockets are formed in the web 7.

Title: Improvements in or relating to the production of melamine
Filed: 1956-11-15
Abstract: Melamine is produced by heating ammonium thiocyanate to 200-375 DEG C. at 5 to 250 atmos. in a rotary horizontally-arranged autoclave in the absence of ammonia, releasing the asg pressure of the autoclave after 15-45 minutes, heating the remaining mass to temperatures of 350-450 DEG  C. at 50-300 atmos. in the autoclave in the presence of ammonia and finally cooling the fused mass after 10-30 minutes.  The cooling of the fused mass may be carried out under ammonia pressure. It is also possible to blow out the melted crude mass through a valve, whereupon the melamine sublimes and can be precipitated on cooling surfaces in especially pure condition.  A detailed example is described.  Comparative experiments describe the use of a stationary autoclave, different reaction times and temperatures and the known method of heating ammonium thiocyanate in the presence of ammonia.

Title: Improvements in directional aerials for wireless receiving stations
IPC: G01S3/06
Filed: 1921-12-30
Abstract: 179,509. Bellini, E. May 2, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Aerials; directive signalling.-A directional aerial for receiving stations is adapted to eliminate azimuthal errors. The Specification states that the errors in the bearings obtained for distances greater than 100 miles are caused by the reflection of the waves by the upper layers A of the atmosphere, and are due to the action of the horizontal parts of the transmitting aerial on the horizontal parts of the receiving aerial. The action of the layers A may be regarded as equivalent to that of an image B of the transmitting station T, the receiving station receiving simultaneously waves emitted by the station T and the image B, and the direction given by the frame R being the resultant of the directions given by the station and its image. To obtain the correct bearing, it is necessary to suppress the effect of the waves from the image B. This may be attained in two ways. (1) A system may be used consisting of a frame R and an horizontal frame H which can turn with the frame R around the vertical axis of the latter. The number of turns of the two windings, which may be connected in series or parallel, have such a relation that, when the vertical winding is perpendicular to the direction of the sending station, the electromotive forces induced in the two windings are equal and opposite. In a modification, the horizontal frame H remains stationary. (2) A system employing a frame inclined to the vertical, and capable of being turned about a vertical axis, may be used.

Title: Improvements relating to power transmission clutches
IPC: F16D13/04
Filed: 1922-12-28
Abstract: 191,061. Frey, E. Dec. 30, 1921, [Convention date]. Clutches, friction; variable - speed gearing.-In friction clutches of the type in which the power and speed transmitted are regulated by variations in the motion of a controlling-member, this controlling- members acts on an auxiliary friction device which transmits magnified movements to the actuating-means for the main clutch. A casing 2, 3, driven by toothed gearing or having flanges 4 to receive a driving-belt, runs freely on a driven shaft 1 and is provided with cylindrical surfaces 8, 9. The auxiliary clutch 11, comprising hinged segments a, b, c, adapted to contact with the drum 9, is expanded by a lever 17 which bears on an adjustable pin 15 and has teeth 18 meshing with teeth 7 on a loose sleeve 5. The fulcrum pin 13 of the lever 17 contacts with a spring-retracted lever 16 fulcrumed at 12 and bearing on an adjustable pin 14, whereby hinged main-clutch segments 10 can be tightened on to the surface 8. An arm 19, keyed to the shaft 1, engages a slot 20 in one segment of the clutch 10 and co-operates with a pin 21 to prevent excessive relative motion of the clutch 11. The sleeve 5 is constantly driven by a cord pulley 6. When the sleeve advances relatively to the driven shaft 1 in the sense of the arrow A, the lever 17 is turned to tighten the clutch 11, which thereupon turns the lever 16 to adjust the grip of the main clutch 10 until the parts 1, 5 are rotating at the same speed. The maximum speed of the pulley 6 is arranged to be less than that of the pulley 2, 3, so that there is always some slip.

Title: Improvements in or relating to photographic cameras
IPC: G03B13/02
Filed: 1957-11-20
Abstract: 854,185. Stereoscopic cameras, camera supports. KAMERA-UND KINOWERKE DRESDEN VEB. Nov. 20, 1957 [Dec. 1, 1956], No. 36132/57. Classes 97(1), 98(1) and 98(2) A camera using 16 m.m. or smaller film is mounted, so as to be adjustable about a horizontal axis at right angles to the optical axis, on lateral arms extending from a head-band which supports the camera on the head of the photographer and the camera shutter and filmfeed are remotely controlled. As shown, a stereoscopic camera has objectives 3, 4 and is pivotally mounted by means of trunnions 1, 2 on arms 106, 107 and clamped, by knobs 101, 102, in a position in which its optical axes lie in the direction of the wearer's desired line of sight. Arms 106, 107 are attached to head-band 105. The camera is electrically operated by remote switches controlling electromagnets 9 and 27 for shutter release and film feed, respectively. Two separate switches which may both be either hand or foot operated provide a single exposure and a series of feed and exposure cycles, respectively. Take-up spool 19 is driven by spring motor 11, 16, 17 and 17<1> initially wound by knob 12 and the tension in film 20 tends to turn sprocket 24 which is fast with disc 25. Energisation of electromagnet 27 releases disc 25 and allows sprocket 24 to turn through half a revolution to feed the film through two frame lengths when disc 25 is again latched by lever 26. Shutter disc 5 carries permanent magnet 8 and is turned through half a revolution on reversing the polarity of electromagnet 9, the duration of exposure thus depending to a small extent on the field strength of magnet 9. The exposure time depends on the speed of rotation of the shutter disc 5 as controlled by remotely varying the current in an electromagnet of an eddy current brake 10. Rubber abutments 52 limit the movement of shutter disc 5. After exposure the film is rewound into cassette 21 by knob 14. For distance finding, the inclination about axis 281, 29<1> of two optical projectors 28, 29 is varied by rotating worm 34 so that their image fields coincide and define the object field of the camera. The objectives 3, 4 which may be coupled together for focusing are then set to the distance indicated on drum 36 or, alternatively, the objectives may be coupled directly with the projectors to focus automatically. In an alternative method of focusing, it is suggested that light sources are placed in the camera or light is reflected into the camera. The camera is intended for the photography of surgical operations and the projectors 28, 29 may be removed in use, the extent of the object field being rendered apparent to the wearer by markers 110, 111 and 112. A multipole rotating magnet may replace the spring motor.

An aircraft feel simulator is as claimed in claim 1 of the parent Specification, and and the control valve 38 is a piston valve coacting with pressure and exhaust ports 39 and 40, the airspeed responsive device 44 applying pressure to the end of the control valve, in opposition to the hydraulic control pressure in the housing acting on the other end of the control valve, through the intermediary of a relief valve 49 held seated against the end of the control valve against the control pressure which is applied to the relief valve through a duct 50 therein by spring 43 assisted by the airspeed responsive device, so that the relief valve opens when the control pressure becomes excessive, and comprises a spring 55 acting on the end of the control valve subject to the control pressure in the direction to assist the control pressure. At very low airspeeds, the tendency for the valve to stick when the forces acting on it are very small is overcome by the spring 55. The simulator is substantially similar to that described in the parent Specification with reference to Figs 1 and 8 thereof, except that the spring 55 is added the strength of spring 43 being correspondingly increased, the duct 42 communicates the control pressure at port 28 to the lower end of the valve 38, and three springs 48 prevent the diaphragm 44 from contacting the push rod 45 at low airspeeds, instead of a single spring surrounding the push rod. A device or devices sensitive to airspeed or Mach number may be coupled to the diaphragm 44 to modify the characteristics of the simulator when a given airspeed or Mach number is attained. Specification 740,510 also is referred to.
