Title: Improvements in or relating to tube bending machines
IPC: B21D9/07
Filed: 1966-03-09
Abstract: 1,133,103. Tube bending machine. HILGERS MASCHINEN UND APPARATE BAUANSTALT m.b.H. 9 March, 1966 [15 April, 1965], No. 10368/66. Heading B3E. A tube bending machine comprises a tube clamping jaw 13 which is moved into the tube clamping position by hydraulic fluid supplied to a cylinder 14 at low pressure, and an arrangement which, when the jaw is in the clamping position, connects the cylinder 14 to a source 27 of high-pressure hydraulic fluid enabling a small cylinder 14 to exert a large clamping force. The low-pressure fluid is supplied by a pump 20 which also supplies fluid to operate the remainder of the machine. When the jaw has been moved into the clamping position a valve 23 is actuated by a pressure relief valve 22 and automatically shuts off the low-pressure supply to the cylinder 14. A motor 26 driving a highpressure pump 27 is simultaneously started to supply high-pressure fluid which exerts a high clamping force on the jaw 13. When the tube is clamped fluid pressure is supplied to one of a pair of cylinders 18, 19 to rotate a shaft 11 through a chain 17. This causes an assembly comprising the cylinder 14, the jaw 13, and a bending pattern (12, Figs. 1 and 2) to which the tube is clamped, to rotate drawing the tube through a slideway (16) and bending it to the profile of the pattern (12). In another embodiment (not shown) a pressure intensifier is used as a source of high-pressure fluid.

Title: Improvements in or relating to vacuum operated fuel feeding systems
IPC: F02B1/00
Filed: 1949-04-19
Abstract: 663,796. Actuation of switches; partly magnetic switches. TRICO PRODUCTS CORPORATION. April 19, 1949. [April 20, 1948] No. 10394/49. Class 38 (v). [Also in Group XXVIII] In a fuel supply system for a motor vehicle, the carburretter is supplied from a gravity flow tank that has a float that controls a valve which alternately connects the tank to the suction pipe connected to the engine manifold, and to the atmosphere whereby fuel is raised from the main tank and allowed to flow to the carburetter. When the suction in the manifold is insufficient, such as at starting, a vacuum pump driven by an electric motor 23 is brought into operation. The pump 18 has an inlet 21 and an outlet 22 that are connected by a bypass passage 42 fitted with a non return valve, and the pressure in the inlet 21 is transmitted through passage 41 to act on a piston 37, loaded by a spring 39, which actuates a switch. The switch comprises a stationary contact 26 and a movable contact 27 carried by a blade spring 28 fixed to an arm 29 pivoted on pillars 30 and connected to the piston 37. The arm 29 has its end adjacent the piston 37 extended transversely to form armatures for a horseshoe magnet 40 to cause rapid making and breaking of the contacts. The contacts 26, 27 are connected in series with the starting switch of the vehicle so that when the engine is started and insufficient vacuum exists for raising the fuel the pump is operated and continues until sufficient vacuum exists for the piston 37 to be drawn downwards to break the contacts 26, 27.

Title: Improvements in or relating to hydraulic oscillation dampers
IPC: F16F9/504
Filed: 1965-03-15
Abstract: 1,072,463. Shock-absorbers. FICHTEL & SACHS A.G. March 15, 1965 [March 17, 1964; Jan. 22, 1965], No. 10776/65. Heading F2S. An hydraulic oscillation damper for attenuating oscillations of resiliently suspended rotary drum units, e.g. in washing machines having centrifuging action, comprises a hollow piston 3 which works in a cylinder 1 and which has through ports 4 which provide high damping and diametrically opposed, and longitudinally offset, flats 5 which communicate with each other through apertures 6 in the wall of the hollow piston 3 to provide a bypass and give a low damping factor when an inertia mass 7, accommodated within the piston, moves from its centrally balanced position in either direction. The mass 7 is dynamically balanced by the springs 9 so that it remains in its central position to close the apertures 6 in the critical rotational range of the washing machine drum unit. At higher R.P.M. range the mass 7 and spring 9 system is brought into resonance so that the by-pass is periodically opened and the damping is reduced. If a clearance is left around the piston 3 the through ports 4 can be omitted. In a modification, Fig. 6 (not shown), the mass (117) has sleeves (118) which, for high damping, close the larger ports (115) in piston end plates (113), (114). In a further modification, Fig. 10 (not shown), an inertia mass (207) is dynamically balanced by springs (208) to normally close an outlet (206) in a port (205) which leads to high damping ports (204) in a piston rod 202. In an alternative arrangement, Fig. 11 (not shown), a cluster of openings in a port through a piston rod are closed by an inertia mass in its central position the mass being balanced by a single spring located below it. In order to prevent the mass from being moved by jets of liquid issuing from the ports in the piston during a high damping stage an additional, normally free, bore (310) is provided to give outlet which provides a counterflow to stabilize the mass (309). The skirt (309) for the mass may be omitted and the bore 310 may be downwardly inclined in the outward direction. The movable mass may be arranged on a piston rod part extended beyond the piston on the opposite side to the rod 2.

Abstract: The invention comprises 2-(cyanomethyl)-1-propene-1,1,3,3-tetracarbonitrile and its sodium, potassium, ammonium and C1- 4 alkylammonium (especially tetra-(C1- 4 alkyl)-ammonium) salts. The alkali metal salts are prepared, for example, by reacting malononitrile with sodium carbonate at 20 to 30 DEG  C. for 8 to 24 hours in an aqueous solution having a pH of between 10 and 11, acidifying the reaction mixture and extracting with ethyl acetate, treating the recovered extract with excess sodium bicarbonate for 1 to 6 hours at a temperature of 20 DEG  to 30 DEG C., recovering the ethyl acetate portion and adding chloroform to precipitate the sodium salt to 2 - (cyanomethyl) - 1 - propene - 1,1,3,3 - tetracarbonitrile. The free acid is obtained by passing an aqueous solution of the sodium salt through a cation exchange resin in the acid phase and eluting with water.  Ammonium and alkylammonium salts are prepared by treating an aqueous solution of the free acid with a hydroxide or chloride of ammonia or the corresponding amine. The 2-(cyanomethyl)-1-propene-1,1,3,3-tetracarbonitrile may also be catalytically reduced with hydrogen to the corresponding polyamine.
