Title: Improvements in or relating to fuel injection pumps for internal combustion engines
IPC: F02M59/36
Filed: 1932-08-08
Abstract: 393,793. Fuel-injection pumps. SULZER FR’RES SOC. ANON., Winterthur, Switzerland. Aug. 8, 1932, No. 22196. Convention date, Aug. 15, 1931. [Class 102 (i).] In a fuel-injection pump the fuel is drawn through a suction port 9 controlled by an oblique edge 17 on the plunger 1 and during the forward travel of the plunger is trapped between the plunger and the accumulator piston 3 until a groove 22 in the plunger coincides with the discharge port 14, when the accumulator piston effects the discharge. It is arranged that the port 14 is again covered by the plunger before the accumulator piston and the pump plunger move away from each other on the return stroke and also that the suction port is opened when the plunger leaves the accumulator piston. The cam actuating the plunger is shaped so that the pump plunger leaves the accumulator piston late in the expansion stroke of the engine. The pump delivery is varied by rotating the plunger during the stroke so that the suction port is cut off during the stroke, or the plunger may be fitted in a rotatable sleeve so that its position at the end of one stroke is different to that at the end of the other stroke. In Fig. 6, in addition to the plunger, a piston valve 24 controls the discharge port 15 and also actuates the suction valve 29.

A pouffe or seat top is made by inserting an open topped, bag-like cover 9 into a cylindrical former 1 with a closed bottom 3, turning the upper edge of the cover 9 over the former rim (7) and retaining this edge by a slidable clamping ring 11, introducing fibrous filling 12, e.g. wood-wool, into the cover 9, compressing the filling 12 to a level below the rim (7), locating an end cover (18) over the turned over edge immediately after releasing the pressure on the filling 12, and press welding the end cover (18) to the turned over edge, the former 1 providing one of the welding electrodes. The filling 12 may be compressed by a pressure plate 13 having a dished lower face. The plate 13 is held in the cover 9 by slidable or pivoted bolts 15 until just prior to the welding operation. A foamed plastics layer 14 may be positioned between the plate 13 and filling 12 and may remain in the cushion. The pressure plate may apply load through a rigid board (21) laid over the filling. The board (21) is sealed in the cushion and provides a base which may be apertured to receive legs. The pouffe bottom is perforated to permit "breathing".

Abstract: 995,010. Forced flow steam boilers; feedwater supply systems. DURRWERKE A.G. June 8, 1962, No. 22386/62. Heading F4A. A steam generator has a number of steam generating sections 8a . . . d connected in parallel between a preheater 2 and superheater 11. The steam generating sections discharge to individual steam and water drums 4a . . . d from which vapour flows to the superheater and water is recirculated around the respective steam generating sections by pumps 7a . . . d. Preheated feedwater is admitted to each drum under the action of level-controlled valves 5a . . . d. In a modification. Fig. 2 (not shown), the preheater and superheater comprise parallel sections 2a . . . d and 11a ... d associated with the individual steam generating sections. In a further modification, Fig. 3 (not shown), the sections of the preheater are connected serially with the steam generating sections and downstream of the control valves. In a modification, Fig. 4 (not shown) of the latter arrangement, water is circulated through both the preheater and steam generating sections and a common superheater serves all the steam generating sections. The steam generators of Figs. 3 and 4 may operate normally as once through generators, recirculation only occurring during starting or at partial load. In a final modification, Fig. 5 (not shown), a common preheater and common superheater serve the steam generating sections but recirculation is effected by a smaller number of pumps operating in parallel.

Title: Improvements in or relating to apparatus for indicating the presence of inflammable vapours or gases
IPC: G01N7/12
Filed: 1929-07-24
Abstract: 331,711. Ringrose, H. T. July 24, 1929. Controllers with safety arrangements.-In gasdetecting apparatus of the type in which the vacuum resulting from the combustion of an inflammable gas mixture in a porous vessel 12 causes the collapse of a diaphragm 9, the collapse is utilized to short-circuit a solenoid 3 which normally retains a switch 1 in series with a lamp circuit in the " make " position. The no-volt coil 6 of a motor switch may be placed in series with the solenoid so that it is also short-circuited. In the illustrated arrangement the lamps 4, filament 5 which effects combustion of the gas under test, no-volt coil 6, and solenoid 3 are all connected in series and the circuit is initially completed by pressing the plunger 2. This action also temporarily connects a shunt resistance 13 across the filament 5 to prevent too sudden heating of the latter. The presence in the porous vessel 12 of a predetermined amount of combustible gas results in the closing of the contacts 9<x> thereby short-circuiting the coils 3, 6 and break. ing the lamp and motor circuits. A hook 17 on the switch arm 1 engages a pin on the motor switch 7 in the " off " position and prevents the motor being switched on until the plunger 2 has been depressed.
