Title: Improvements in or relating to liquid pressure remote control systems
IPC: B64C25/22
Filed: 1936-02-05
Abstract: 469,906. Remote control systems. AUTOMOTIVE PRODUCTS CO., Ltd., and BROWN, F. V. Feb. 5, 1936, No. 3529. [Class 69 (ii)] [Also in Group XXXIII] In a liquid-pressure remote-control system comprising a master unit and a double acting slave unit normally connected through a pair of pipe lines there is provided an auxiliary pipe line extending from the source of pressure to one side of the slave unit and fitted adjacent the master unit with a manually operated valve for connecting such pipe and at the other end with an automatic pressure-operated valve which when the auxiliary pipe line is fed with pressure liquid, disconnects the main pipe line from the slave unit. The pressure pump B is normally connected with. the pipe lines 12, 13 of a double acting slave unit A of which the pipe line 12 also passes on to a single acting slave unit G which acts to withdraw a latching pin when the slave unit A forms part of the retractible gear of an aeroplane undercarriage. In this main system a two-way control valve D is disposed for operating the slave unit in the required direction. If the pressure pump B is replaced by a hand pump E the valve F is set to connect the pump E with the main system. Non-return valves 23, 24 prevent one pump from feeding to the other. When it is desired to use the auxiliary system H with the hand pump E the valve F is set to connect up the pipe H and disconnect the pipe 22. The slave unit A and unit G have automatic valves 25, 26 each being in a casing having leads to the pipes 12 and H from unions 12a, 42, respectively. The union 12a communicates through a series of apertures 31 with an axial passage 32 of the annular valve seating 33. The valve 37 is provided with a rubber facing 41 and is under control of the spring 35. In normal working the pressure in the pipe line 12 holds the valve over to the left as in Fig. 2. If the main system fails and the auxiliary system is operated, pressure behind the valve forces it to the right shutting off the line 12 from the chamber 28 leading to the slave unit and opening up the line H thereto. The two-way valve F has a conical body 45 held on its seat by a spring 46 and provided with cut-out parts to form passages for connecting or closing the pipe lines. The body provided with a hole 55 whereby the rubber packing 50 is subjected to the liquid pressure. When two slave units A in parallel for simultaneous operation of an aircraft undercarriage are employed, with the hand pump E and mechanically driven pump B for alternative actuation as described in Specification 448,478, an automatic valve 25 is incorporated and a valve F is fitted on the system normally operating other slave units J from a hand pump K whereby on failure of the system E, 12, 13 the operation of the units A may be effected from the pump K.

Title: Improved method and means of controlling multi-cylinder internal combustion engines
IPC: F02D1/00
Filed: 1934-02-06
Abstract: 434,657. Regulating. HESSELMAN MOTOR CORPORATION, Ltd., 56, Kingsway, London. Feb. 6, 1934, No. 3864. Convention date, Feb. 6, 1933. [Class 7 (vi)] [See also Groups XXVIII and XXXVII] In multicylinder engines of the airless fuelinjection type operating with throttling of the air supply, one or more cylinders are cut out at reduced loads by means of the vacuum in the induction pipe, to facilitate obtaining proper proportions of fuel and air under these conditions. Fig. 1 shows an engine with an air throttle 20 and fuel pumps B having their plungers 30 actuated by cam-operated tappets 54, one or more of the pumps being cut out of action, when the throttle 20 is nearly closed, by a solenoid 106 rotating a sleeve 80 so as to move the appropriate pump plungers out of the range of their tappets. The solenoid is actuated by a contact 112 carried by a diaphragm 116 so as to be drawn down into engagement with a fixed contact 104 by the vacuum in the air-inlet passage 14. The sleeves 80 are provided only in connection with those cylinders which are to be cut out, this being effected by contact of a gap in the sleeve 80 with a collar 68, Fig. 3, which lifts the fuelpump plunger 30 out of the range of the tappet 54. The stroke of the fuel pumps is adjusted by similar sleeves 64, which also act on the collars 68 when operated by suction-actuated pistons 90. Chattering of the contact 112 may be prevented by causing the diaphragm 116 to seat in its uppermost position against a flange 126, the space within which is open to the passage 14. In modifications, the contact 112 may be actuated directly from the throttle spindle, or a purely mechanical lost-motion connection may be arranged between the throttle valve and the sleeves 80 which cut out the fuel pumps. The invention may be applied to engines operating as described in Specifications 282,731, [Class 7 (iii)], and 282,735, [Class 7 (vi)].
