Patent GB-317083-A (GB)
IPC: B64C25/46
Filed: 1929-08-07
Abstract: 317,083. Messier, G. L. R. J. Aug. 10, 1928, [Convention date]. Fluid-pressure; force-transmitting mechanism. -For regulating a fluid-pressure-actuated brake, particularly for aeroplane wheels, a number of parallel cylinders contain pistons which act upon one face of a common transmitting element, the other face pressing against a rod or roller to actuate the brake, and fluid is admitted only to the required number of cylinders. The brake pressure on the two sides of the machine may be varied by having separate groups of cylinders for actuating the two brakes, or a single group may be used and the pressure of the transmitting element variably distributed. The fluid pressure may be derived from a skid actuated pump. Fig. 6 shows a series of cylinders a<1>, a<2>, for example four, having plungers acting on a common element d sliding on a guide e', fluid pressure being admitted to the required number of cylinders and the remainder left open to exhaust. The element d acts through a roller q upon a floating lever r connected at its ends to the pistons of two hydraulic transmissions connected to the brakes on the two sides of the machine. The position of the roller q is varied by a connection to a, lever t which controls the rudder. Alternatively the element d may act through a hydraulic transmission or directly through a rod connected to the roller q through a swinging rod, and the lever r may apply the brakes through mechanical transmission. Fig. 3 shows a valve for admitting fluid to the four cylinders a<1>, a<2>, &c. Two pistons i<1>, i<2> on a common stem divide a cylinder h into three chambers h', h<2>, h<3>, the chamber h<2> being in communication with the pressure fluid through a pipe j, and the chamber h<3> being connected to exhaust through a pipe l. A passage i<*> in the valve stem connects the chambers h<1>, h<3>. By moving the valve stem, the required number of ports k<1> - - k<4>, connected to the cylinders, are put into communication with the chamber h<3>, the remainder being left open to exhaust through the passage i<*>. A spring plunger m engages notches n in the valve stem to retain it in any of its five positions. The pipe l may lead to a chamber having an airspace under low pressure so as to return any exhausted fluid to the pump actuated by the tail skid.

Title: Polyethers
Inventor: ULYATT JEFFREY MARTIN
IPC: C08G18/48
Filed: 1964-06-10
Abstract: Polyethers are prepared from (a) an aliphatic polyhydroxy compound having at least 3 hydroxy groups; and (b) and a ,b -alkylene oxide using an amine as catalyst, and in the presence of, as diluent, a polyether which is itself the product of the reaction of a compound (a) and a compound (b) in the presence of an amine. The polyhydroxy compound is partly suspended in the diluent at the start of the reaction. Water may be added to the reaction system. The preferred polyether products are those having 1 to 2 oxyalkylene groups per hydroxy group of the polyhydroxy compound.  Typical compounds (a) are sucrose, trimethylol ethane, di-pentaerythritol mannitol, glucose, and a -methyl glucoside, and sorbitol.  Typical compounds (b) are propylene, ethylene, 1,2- and 2,3-butylene, and styrene oxides. Suitable catalysts are those strongly basic secondary or tertiary amines which do not have an aryl group bonded to nitrogen e.g. N-methyl benzylamine, dimethylamine, trimethylamine, tri-n-propylamine, pyrrolidine, piperidine, 4-methylpiperidine, N - methyl and N - ethyl-piperidine piperazine, tetramethylguanidine, N,N,N1,N1 - tetramethylethylene, propylene, butylene or triethylene diamines, and alkanolamines e.g. N,N-dimethylethanolamine.  In the examples 1-6 and 8, various polyethers are prepared and used as diluents in the same reaction to prepare further amounts of similar polyethers.  In Example 7 a sorbitol/propylene oxide polyether is prepared and used as diluent in the preparation of a sucrose/propylene oxide condensate.

Title: Improvements in or relating to motor operated tuning mechanism for radio receivers
IPC: H03J5/14
Filed: 1938-08-17
Abstract: 518,229. Push - button tuning of wireless receivers. COLE, Ltd., E. K., and BRADFIELD, G. Aug. 17, 1938, No. 24200. [Class 40 (i)] In an arrangement in which the tuning motor is driven until a gap in a conducting segment registers with a contact-finger selected by a station - selecting button, the speed of the segment is reduced when the finger approaches the final tuned - in position by periodically interrupting the motor circuit. In one arrangement, Fig. 1, conducting members 2, 3 are arranged in the gaps and are connected to the motor windings 6, 9 through the coils 4, 8 of a thermal interrupter .5. Consequently when the contact finger is left by the segment 1 the motor continues to run but after a short time the interrupter breaks the motor circuit and its own. When the interrupter cools, these circuits are remade and the motor is driven again for a short time. A considerable reduction in speed is thus brought about and the segment is brought to rest with the finger in the centre of the gap out of contact with the members 2, 3. In a modification, Fig. 2, an interrupter disc 11 which is driven at a higher speed than the tuning segment and the conducting members of which are connected to a thermal switch which interrupts the motor circuit is arranged near the gap so that when the interruper wheel reaches the contact finger, the motor circuit is intermittently broken and the speed is reduced. Specification 509,750 is referred to.
