Title: Method of obtaining polymers of acrylic series
IPC: C08F2/00
Filed: 1979-05-29
Abstract: A method of obtaining polymers of acrylic series comprising polymerization of starting monomers at a total concentration of 40% by weight in the presence of radical initiators. The polymerization is carried out at the temperature of decomposition of the initiator used and is continued until obtaining a gel effect. After that the reaction stock is cooled down to a temperature of glass-transition of the polymer and a conversion degree of 50 to 90%. The thus obtained pre-polymer is then granulated and dried with a heat carrier, for example air, consecutively under regimes of pneumatic transport, cyclone, fluidized bed and filter bed. The method of obtaining polymers of acrylic series can be used in production of water-soluble polymer materials used as surface-active agents for industrial sewage and in the drilling technology, and as flotation agents in ore- and coal-mining industries.

Title: A method and a device for adjusting an image-reproducing apparatus
IPC: H02P7/291
Filed: 1982-03-19
Abstract: A method and a device for adjusting an original plane (8), an objective plane (6), and an image plane (4) in an image-reproducing apparatus by means of one or more D.C. motors with a great torque. The motors are controlled by means of voltage pulses each motor (1) being braked after each pulse supply. The planes are adjusted to approximately the desired magnifying percentage by known means. Final adjustment is determined by giving one of the motors a pulse and sensing the displacement of its associated plane. From this the pulse width of a given number of pulses or the number of given pulses is determined which will result in the final positioning of the said plane. <IMAGE>

Title: Pressure cookers
IPC: A47J27/092
Filed: 1982-04-07
Abstract: The body member (1) and cover member (5) of a pressure cooker are adapted to be held together by means of inter-engageable pairs of lugs (8, 9, 10, 21 and 13, 12, 14, 24) arranged on each member.

Title: Conveying rod-like articles
Inventor: BROWN ANTHONY ROBERT
IPC: B65G43/08
Filed: 1983-07-26
Abstract: A flexible membrane (54) confines rod-like articles e.g. cigarettes in a transition zone (10) (which may be the filling head of a tray filler). The membrane is extended or retracted under tension in response to pressure of articles in the zone.

Title: High definition video signal transmission
Inventor: DREWERY JOHN OLIVER
IPC: H04N7/12
Filed: 1984-03-01
Abstract: A high definition video signal, such as a 1249 line 2:1 interlaced signal is transmitted through a main channel and an auxiliary channel, the main channel being compatible with a conventional (625 line) video signal. The high definition signal is separated in frequency space into the two transmitted signals namely to high and low pass bands relative to the repetition frequency of the signal. In a first example (Figures 1-2) the horizontal frequency of a digital input signal is the criterion, low frequency components being transmitted in the main channel and high frequency components transmitted in the auxiliary channel, after frequency conversion. These component signals are sampled at twice the 625 line signal sampling frequency and main and auxiliary signal samples taken alternately in time. In a second example the main channel takes low frequencies (11, 12, 13, 14) defined in the vertical frequency/temporal frequency plane and the auxiliary channel takes down-converted high frequencies (21, 22, 23, 24) in the said plane. <IMAGE>

Title: Method for extracting sulphur from coals and lignatic materials
Inventor: WHITTINGHAM BARRON S
IPC: C01B17/033
Filed: 1984-04-24
Abstract: Coal to be desulphurised is first ground, and the resulting particles are placed in a container with trichloroethylene, tetrachloroethylene or other ethylenic compound, as a solvent, and the resulting mixture is heated to the boiling point of the compound. The mixture is maintained at the boiling point for a selected time interval, and the coal is then removed by filtration. The remaining filtrate is permitted to cool slowly to room temperature, and this slow cooling causes free sulphur which was removed from the coal to precipitate from the solution as monoclinic needles of high purity. Organic sulphur compounds, such as the mercaptans and thiophenes dissolved out of the coal remain in solution.

Title: Fuel injection pumping apparatus
Inventor: SKINNER ROBERT THOMAS JOHN
IPC: F02M41/14
Filed: 1984-05-08
Abstract: A fuel injection pumping apparatus for supplying fuel to an internal combustion engine is of the rotary distributor type and has a cam ring 18 actuating pumping plungers in a distributor member and a cam ring 29 which controls the operation of a spill valve also carried by the distributor member. The positions of the cam rings are determined by pistons 50, 60 which are in turn controlled by resiliently loaded servo valves 53, 62 subjected to separate control pressures. The resilient means 63 which loads the servo valve 62 is supported on abutment arm 67 carried by the piston 50 whereby when the piston 50 moves to alter the timing of fuel delivery the piston 60 will also move to maintain the quantity of fuel delivered constant. If the piston 60 is moved to alter the quantity of fuel delivered there is no corresponding movement of the piston 50. <IMAGE>
