Abstract: 1,242,170. Polyurethanes. E.I. DU PONT DE NEMOURS & CO. 9 April, 1969 [10 April, 1968; 31 May, 1968], No. 18306/69. Heading C3R. Polyurethanes contain in the polymer chain tertiary N atoms bound to two non-carbonyl carbon atoms which are not part of an aromatic ring and which are further bound to a t-butyl radical. They have repeating units in which R and R<SP>1</SP> are divalent aliphatic, cycloaliphatic or araliphatic radicals (M.W. < 400) at least one of which contains the said tertiary amine nitrogen. The polymers have an inherent viscosity of 0.07-0.6 measured in dimethylacetamide at 25 C. at a concentration of 1 g. per 100 ml. of soln. In preferred polymers R<SP>1</SP> is where R<SP>11</SP> is a C 2-3  alkylene group. R may be 4,4<SP>1</SP>-methylenedicyclohexyl or hexamethylene. The polymers may be prepared by reacting a diol containing the required tertiary N atom with a diisocyanate. The polymers are useful for stabilizing segmented polyurethanes (e.g. those of Specification No. 1,102,819) against discoloration by light and smog. The polymer should be present in an amount to provide at least 0À014% of tertiary amine nitrogen bonded to t.-butyl per kg. of the segmented polyurethane.

Abstract: 1,242,038. Wet separation of solids. BARMAG BARMER MASCHINENFABRIK A.G. 17 April, 1970 [17 April, 1969], No. 18437/70. Headings B1D and B2H. An apparatus for separating plastics granulate from a mixture consisting of granulate, granulate waste and water comprises a primary separator 1 (2) having a screen 9 consisting of spaced bars 10 arranged in the flow path of the mixture to be separated, a main separator 3 having a set of conical screen elements 18 and a set of funnel-shaped screen elements 19, the elements of each set being arranged one above the other in the form of a tower, an overflow chamber 4 connecting the primary separator with the main separator and an inlet spout 5 for the mixture to be separated. As shown, two primary separators 1, 2 are mounted on opposite sides of the main separator 3. Each primary separator consists of a container 6 in which is removably arranged an insert 7 having a removable perforated base 8. The screen bars 10 and an inlet tube 11 are fixed together to a frame 13 supported on projections 15 in the upper part of the insert 7. The frame 13 is covered by a coarse screen 14. A curved baffle 16 fixed to the frame 13 serves to deflect liquid issuing from the primary separators towards the main separator. The main separator 3 comprises a trough 17 at the bottom of which is inserted a discharge funnel 20 in which is in turn inserted a column of funnel-shaped screen elements 19-19" arranged one above the other. Coaxially mounted within the funnel-shaped elements is a column of conical-shaped screen elements 18-18", the lower one of which is supported by a filtrate outlet tube 23 which opens into a filtrate discharge funnel 27. The top of the trough 17 is covered by a screen plate 26. For cleaning purposes, a valve-controlled outlet 29 is arranged at the bottom of each primary separator and communicates with the funnel 27 through a pipe 30. In operation, the mixture to be separated is fed via the spout 5 to the inlet tube of one of the primary separators 1, 2 at the bottom of which the flow is reversed and the mixture flows upwards against the screen bars 10 which retain the coarse granulate waste while the fine granulate and the water flow into the chamber 4 and thence into the main separator 3, the screens 14 and 26 retaining any coarse particles still present. The fine granulate is dewatered by passing down the conical and funnel-shaped screen elements 18, 19 in turn until it finally enters the discharge funnel 20. The separated water which passes into the interior of the screen elements 18-18" and to the exterior of the screen elements 19-19" is finally discharged through the funnel 27. In a modification the primary separators may be arranged immediately adjacent each other. In a further modification the bars 10 of the primary separators may be arranged horizontally.

Title: Improvements in and relating to Internal Combustion Engines.
Inventor: FOSTER LEWIS LEROY
IPC: F01L5/06
Filed: 1917-12-18
Abstract: 115,776. Foster, L. L., and Ruehmling, J. H. Dec. 18, 1917. Two-strok-cycle engines; crank chambers.-A piston 37 works in a double-acting cylinder 20 which is surrounded by a trunk piston 33. The piston 33 serves as a valve and compresses the combustible charges which enter from the carburettor into the spaces 54, 55 on each side of it. The charge compressed in the space 54 passes through the passage 56 and port 69 to the upper combustion chamber 53, while that which has entered the space 55 through the port 66 escapes, after compression, through the port 57 to the lower combustion chamber 52. There is a common exhaust port 62 in the cylinder 20. Both pistons are attached to the same cross-head 36, which is connected by long rods 46 to the cranks 12. The connecting-rods pass through sliding covers on the top of the crank chamber, which prevent oil from being splashed out.

Title: Improvements in fuel pumps for internal combustion engines
IPC: F02M59/02
Filed: 1920-07-06
Abstract: 146,972. Mader, O. April 27, 1917, [Convention date]. Channels in cylinders and valves.-The piston 2 of a fuel-pump for an internal-combusticn engine is packed by lubricant in a chamber 14 maintained at a higher pressure than the pump delivery pressure. In one form, the lubricant is supplied to the chamber 14 by a tank 16 and is forced past a loaded valve 21 and through a passage 24 to the inlet side by the annular portion 26 of the piston during the delivery stroke of the piston. The pressure of the spring 22 on the valve 21 may be assisted by connecting the pump chamber to the upper side of the valve by a conduit 25. In another form, the valve 21 is replaced by an adjustable needle valve for varying the lubricant pressure, and the pump delivery valve closes the end of the barrel and has a guide tube projecting into the barrel. In another form the forward portion of the piston is hollow and open at the front end and has a port connecting its interior with the chamber 14. A guide tube carried by the delivery valve, which closes the end of the barrel, works in the hollow piston and is lubricated by the lubricant admitted to the interior of the piston. The lubricant pressure helps to open the delivery valve. In another form the delivery valve consists of a mechanically actuated piston surrounded by two annular chambers communicating with the chamber 14. Or the piston valve .may be stepped and provided with throttling screws to provide its own pressure lubricant. In all forms instead of using a stepped portion of the pump piston to compress the lubricant, a separate piston, working in unison with the pump piston, may be used.

Title: Surface elastic wave memory correlator
IPC: G06G7/19
Filed: 1976-05-10
Abstract: 1518365 Correlation THOMSON-CSF 10 May 1976 [13 May 1975] 19186/76 Heading G1U In a correlator using a surface wave delay line, the two signals being correlated modulate a high frequency carrier signal and are applied successively to the line, and transducers which are uniformly distributed along the line are used a) to sample the first modulated signal, which samples are stored, and b) to sample the second modulated signal, the stored and second sampled signals being applied to non-linear elements to provide product signals which are then added to produce a modulation envelope corresponding to the correlation. After application of the first signal V 1 (t) consist to the input transducer P, when the surface wave extends along the line DL, FET switches I 1  are closed, charging capacitors C 1 -C n  to the positive peaks of the instantaneous signals at the transducers E 1 -E n . These direct voltages reverse bias the varicap diodes DC 1 -DC n , and each has a capacitance C v -α V 1  k where V 1  k is the sampled voltage. When the second signal V 2 (t) cos wt is propagating along the line, FET switches I 2  are closed. Thus, the transducer outputs pass via capacitors C 1 -C n  (zero impedance at the carrier frequency) to the parallel capacitors C o  and DC 1 -DC n . By adjusting the capacitors C o  to equal the constant components C v  in the varicap capacitances, the difference between the currents flowing to the two inputs of the amplifier A is solely a function of the product of the samples V 1  k and the value of the corresponding second signal V2k. The summation of these products in the amplifier A provides the correlation signal providing enough transducers are provided along the line. The transducers must also be positioned such that they respond to the same phase angle of the carrier wave i.e. are positioned at integral wavelengths of the carrier wavelength in the delay line medium.
