Title: Improvements in electric fuse switches
IPC: H01H9/10
Filed: 1935-03-18
Abstract: 452,518. Switches held set and freed mechanically. HOPE, V., Upton Hall, Macclesfield. March 18, 1935, No. 8300. [Class 38 (v)] The movable contacts of a triple pole switch fuse are formed of two strips bent round at one end to form contacting parts E2 while the other ends are shaped so as to be clamped by screws 12 round the end caps of cartridge fuses F. The central parts of the contacts are held together by screws 11 and are loosely mounted between pairs of insulating carrier bars J, J<1>, the three pairs of bars, together with two end frames G being clamped together by nuts 17 on transverse bars 15, 16 to form a unitary contact structure. The outer corners of each end frame G are pivoted to a pair of bell-crank levers K, K<1> pivoted to the lid and connected by links 29 so that the line joining the movable contacts keeps parallel to the line joining the fixed contacts. An operating spindle B journalled in extensions A<2> of the lid is driven with lost motion by a handle H and is connected by links C, 35 to the frame G to close the switch against the action of a spring S, the switch being held closed by oversetting the links C, 35 against a stop 39. The outward movement of levers C is limited by rubber cushions 38 on the lid. Interlock levers K<2>, K3, driven by the bell-crank levers K, co-operate with projections 41 on the casing to prevent the lid being opened while the switch is on. A headed thumb screw 42 on one of the levers K2 can be screwed in to holes in the lid to lock the mechanism in either position. When the lid has been opened and the switch mechanism moved to the on position the tail 45 of a spring-urged catch M engages a pin 46 of lever C and prevents accidental movement of the mechanism to the off position to avoid damage to an operator replacing fuses. Specification 291,518, [Class 38 (i)], is referred to.

Abstract: 609,596. Gas turbines. PARSONS & CO., Ltd., C. A., and WILLIS, D. C. P. March 18, 1946, No. 8352. [Class 110 (iii)] In a gas turbine plant in which the compressor and turbine are disposed alongside one another and in parallel relationship to the combustion chamber, the pipe connecting the turbine and the combustion chamber is disposed in such relation to the points at which the turbine and combustion chamber are anchored that in operation it will remain substantially parallel to its initial position. Air delivered by a compressor 2 passes by way of pipe 6, heat exchanger 5 and pipe 7 to a combustion chamber 4. Combustion products flow by way of a pipe 8 to a turbine 1, and are exhausted through a pipe 9 to the heat exchanger 4. The compressor is driven by the turbine. The turbine is fixed to the bedplate adjacent the pipe 9, and the compressor is fixed to the bedplate at either the inlet or discharge end. The free ends of the turbine and compressor are each free to slide between guides. The combustion chamber is supported by vertical rods, the brackets 11 connecting it to the rods being at approximately the same level as the centre line of the turbine. A guide 10 allows sideways movement, but prevents endwise movement. The fixing points of turbine and combustion chamber are situated at such distances D and E respectively from the pipe 8 that the increases of these dimensions due to thermal expansion are equal, so that pipe 8 remains parallel to its former position. Similarly, dimensions Y and Z are in such relation that, on expansion of pipes 7 and 8, the combustion chamber remains parallel with the other units.

Patent GB-240503-A (GB)
Title: Improvements in or relating to carburetters
IPC: F02M9/06
Filed: 1924-04-08
Abstract: 240,503. Morris, M. C. April 8, 1924. Spray carburettors.-The carburettor described in Specification 211,910 has a main air passage 3, 4 controlled by a transversely sliding throttle piston 7 cut away at 10 on the air inlet side and carrying a shroud 8 adapted to slide loosely over the fuel nozzle 5 located in a well 6. The shroud is cut away on the engine side at 9 to form an opening which is progressively exposed as the throttle is raised. Air may be admitted to the lower part of the nozzle chamber through bore 11, orifice 12 and bore 13 provided with a screwed valve 14, and also through orifices 19, 20, 21 and bore 16 which contains a ball valve 17 adapted to be raised at increased suction to close the orifice 19. A groove 36 in the throttle piston admits a small amount of air for idling. A carburettor thus constructed has an inherent defect in that too much air is admitted between the shroud and the nozzle at throttle positions approaching the fully open, and the invention consists in providing an auxiliary fuel nozzle adapted to deliver fuel into the main air stream after the throttle has been opened a predetermined amount. The auxiliary nozzle 23 is supported by a member 24, 29 held by a screw 30 and has its outlet opposite a port 25 in the casing. It projects through the end of a rotatable, thimble 31 which may be adjusted by an arm 32 to vary the inlet of air through an orifice 34. In a modification, Fig. 7, the nozzle projects into a relatively large opening 25<a> and may be adjustable laterally in said opening to vary the fuel delivered. Additional air may also be admitted on the engine side of the throttle valve through orifices 38, Fig. 2, in a plate 37 rotatable through an arm 40. Similar means may be used in connection with the auxiliary nozzle, the several air passages leading to a common pocket in the casing wall the said pocket terminating in an orifice similar to 25, Fig. 1. A suitable position for the orifice 25 is opposite the groove 36 when the throttle is closed, so that the auxiliary nozzle may be employed as a slowrunning device. According to the Provisional Specification, the parts 24, 29 may be in the form of adjustable telescoping tubes, and air may be admitted thereto.

Abstract: 1,045,258. Radar. M.E.L. EQUIPMENT CO. Ltd. March 3, 1965, No. 9081/65. Heading H4D. In apparatus for monitoring the rate of flow of objects along a predetermined path, ensuing Doppler beat frequencies from radar reflections are passed to two paralleled frequency-discriminating channels each of which includes filter means connected to an integrating circuit; the outputs of the two channels are connected to an indicator via a differential relay. In the embodiment, which is applied to monitoring traffic flow on a motorway, one channel passes frequencies corresponding to vehicle speeds below a certain speed, e.g. 30 m.p.h., and the other passes frequencies corresponding to vehicle speeds above that speed, the differential relay giving an audible or visual alarm when the traffic generally falls below that speed. The channels each include an amplifier of adjustable gain to control apparatus sensitivity to vehicles in the " alarm " condition as compared with the " safe condition"; and the period for which vehicles may continue in the "alarm" state before the alarm is given is controlled by selection of the time-constants of the integrating circuits.
Patent GB-862575-A (GB)
Title: Preparation of trifluoroacetyl fluoride and its derivatives
IPC: C07C51/58
Filed: 1959-03-17
Abstract: Trifluoroacetyl fluoride is prepared by contacting at 140 to 225 DEG C. a mixture comprising tetrafluoroethylene and oxygen with finely divided carbon or with silver oxide as catalyst.  The oxygen is preferably diluted e.g. as in air.  Preferred carbon catalysts are derived from cellulosic materials, especially activated coconut or wood charcoal; they may be pretreated in an inert atmosphere at 200-400 DEG C.  The silver oxide may be on a carrier and other metallic oxides and peroxides may be present, e.g. of alkaline earth metals, zinc or copper.  The reaction is exothermic and the temperature may be controlled by adjusting the volumetric proportion of oxygen in the mixture, e.g. by adding inert gaseous diluents and/or using excess tetrafluoroethylene; the volumetric ratio of tetrafluoroethylene together with any diluent present to oxygen should be at least greater than 10.  The catalyst may be fixed, moving or fluidised and may be regenerated by heating in an inert gas continuously or batchwise.  The trifluoroacetyl fluoride may be hydrolysed with water or trifluoroacetic acid or may be reacted with a base to give a salt of the acid, with an amine to give an amide, or with an alcohol to give an ester.
