IPC: F04B49/24
Filed: 1962-03-31
Abstract: 982,927. Compressors. NORMALAIR Ltd. March 6, 1963 [March 31, 1962], No. 12479/62. Heading F1N. A compressor comprises a piston 13 operating within a cylinder 12, a valve plate 2 provided with valves 5 and 6 being disposed between the cylinder 12 and a cylinder head 1 in which are formed suction and discharge chambers 4 and 3, respectively, the valve-plate 2 having a by-pass port 11 which is controlled by a piston 14 the operation of which is controlled by a pilot valve 7, the latter when open allowing compressed fluid from the discharge chamber 3 to pass through a port 8 and a duct 9 to exert pressure on the piston 14 so as to close the port 11, and the valve 7 when closed preventing the fluid from passing to the piston 14, so unloading the compressor. The valve 7 is preferably operated by a solenoid but may be operated by hydraulic, pneumatic, cable or rod means. The piston 14 is biased to the closed position by a spring 15, a second stiff spring 17 being provided to limit the opening movement of the piston 14 which is adapted to permit fluid to bleed from the duct 9 to the suction chamber 4. If the compressor has more than one cylinder a single pilot valve may control the operation of a plurality of by-pass pistons, more than one of which may be associated with each cylinder.

Title: Improvements in or relating to the polymerisation of hydrocarbons
IPC: C07C2/20
Filed: 1943-08-04
Abstract: <PICT:0584428/IV/1> A process for the manufacture of a hydrocarbon product containing a major proportion of tri-isobutylene comprises contacting an aliphatic hydrocarbon material containing at least 5 per cent by weight of isobutylene in the gaseous phase with gaseous boron fluoride as a polymerization catalyst for a period of less than one second and separating a product containing a major proportion of tri-isobutylene.  The preferred proportion of boron fluoride is from 0.1 to 1.0 per cent by weight based on the isobutylene, and the preferred contact time from 1/5 to 1/2 second. Temperatures of room to 150 DEG  C. and pressures from 2 to 500 lbs. absolute are preferred, but are not critical.  The limitation in contact time may be provided by quenching the catalyst in the product with a fluid immiscible therewith.  Specified fluids are steam, water, aqueous caustic alkali and aqueous or gaseous ammonia.  The unreacted gases may be recycled.  Suitable feed stocks include pure isobutylene, mixtures with n-butylene, or other straight-chain olefins and/or with low molecular weight paraffin hydrocarbons.  A preferred form of apparatus is shown. Feed stock passes via line 1 to heat-exchanger 2, to line 3 where it meets boron fluoride gas from line 4, to a mixer 5 and through a reaction coil 6.  From 6 the product passes to line 7, meeting steam from line 8, to scrubbing tower 9, meeting water from line 10 and the unreacted gases pass out via line 11.  The products pass through line 12 to separator 13 from which the water is drawn off through line 14 and the products through line 15 to storage 16.

Filed: 1952-05-19
Abstract: 709,160. Stabilizing ships. KEFELI, M. M. May 19, 1952 [May 22, 1951], No. 12565/52. Class 113(1) In a device for stabilizing ships comprising slots 8 in the ship's sides 1. below the waterline, a circular segmental blade rotatable within each slot about an inclined axis 6 under the hydrodynamic action only of the water stream impinging against the blade, a watertight casing 7 containing each blade and in communication with the external water through the slot 8, and locking means (stops 19, 20 and rocking shaft 30) for stopping each blade in a projecting position for stabilizing purposes or in a retracted position, the locking means (shaft 30) is actuated by an electromagnet 39 responsive to a central switch 54 the confrol member 52 of which is of the stick type and is adapted to be rocked in all directions. The blades, which are arranged between the ship's frames 2, are inclined so that where one (e.g. 11) receives a downward thrust from the impinging water, the next (e.g. 12) receives an upward thrust, and each has a braking device 56 to slow down its motion at the end of its rotation to or from its projecting or retracted position. The blades, arranged in groups 11-16, 21-26, 31-36, 41-46, are locked in projecting or retracted positions by rocking the control stick in the direction required to counteract roll or pitch, the blades of the same inclination in the same group being controlled to operate step-wise whereby the number of blades brought into play will vary proportionally with the movement of the stick.

Title: Improvements in or relating to compressor regulators
IPC: F04B49/02
Filed: 1939-04-27
Abstract: 528,087. Fluid-pressure servomotor-control systems. MOSS, E. W. (Ingersoll-Rand Co.). April 27, 1939, No. 12617. [Class 135] A regulating arrangement for motor driven compressors in which the motor runs at minimum speed under light loads comprises a speed governor 67 for the motor the setting of which is regulated by a fluid pressure-servomotor 107, a similar servomotor 27 being provided to regulate the unloader 17 of the compressor, the servomotors being controlled by independent auxiliary valves 131, 36 respectively operated by the discharge pressure of the compressor and at different pressures. As shown in Figs. 1, 2, a compressor 1 is directly driven by an internal combustion engine 7, both being supported on a truck 3. The centrifugal governor 67 is arranged on a shaft 61 driven by the motor 7 and operates the throttle 87 thereof through a lever 81 and a link 85. The governor loading spring 89 also acts on the lever 81 and is adjusted by a plunger 97 operable from the servomotor 107 through levers 103, 117 and a connecting link 105. The unloader, Fig. 2, comprises a spring-opened double beat valve 21 arranged in the compressor inlet pipe 9. The valve 21 is closed by the piston 29 of the servomotor 27 under the control of an auxiliary valve 36 comprising a casing 37 housing a closure member 41 adapted to close on an upper seat 43 under an adjustable spring 47 and to be moved to a lower seat 51 controlling the escape to atmosphere by the pressure in a pipe 39 acting on the upper end of the valve. The pipe 39 is connected to a receiver 13 for fluid discharged from the compressor through a pipe 11. The servomotor 107 contains a spring-pressed piston and is controlled by a similar auxiliary valve 131 actuated by the receiver pressure through a pipe 133. The auxiliary valve 36 is set to open at a higher pressure than the valve 131 and due to the seating area of the closure members the pressure required to open the valves is greater than that necessary to maintain them open so that the two valves also close at different pressures. With both auxiliary valves closed, the governor is set for maximum speed and the pressure in the receiver builds up to a predetermined high value at which the governor is changed over to its minimum speed setting. If the receiverpressure rises to the maximum pressure the valve 21 is closed so as to unload the compressor. If the load on the compressor now increases the receiver pressure falls to a point at which the auxiliary valve 36 closes and the compressor is reloaded. However unless the load increases still further to cause a corresponding drop in the receiver pressure, the auxiliary valve 131 will not be opened and the motor will continue to operate at its minimum speed. Even when the load does so increase the governor setting is changed with a predetermined delay due to the restricted escape of fluid from the servomotor 107.
