Title: Improvements in or relating to controlling mechanism for heating installations
IPC: G05D23/275
Filed: 1942-09-04
Abstract: 562,173. Automatic control systems. WATFORD ELECTRIC & MANUFACTURING CO., Ltd., and VUILLE, B. A. Sept. 4,1942, No. 12535. [Class 38 (iv)] [Also in Group XXXVII] A time and temperature operated control of a heating installation comprises a thermostat responsive to external temperature adjustable to start up and shut down the heating each at a predetermined temperature, and clock driven means operable cyclically to adjust the thermostat to vary the heating temperature between the two limits during a predetermined starting - up period and shutting-down period. In one arrangement, an external phial 12 connects with a bellows 14 to move a contact arm to close contacts 11 on a fall in temperature to an extent which can be regulated by screw means 20 controlling the pull of a spring 17. The rotation of the screw is effected one way or the other by means of a rack 22 and pinion 21 on the screw. The rack, pivoted at 23 is actuated according to the movement of an adjustable cam 27ABC rotated by clock means 28 once in 24 hours. As shown the contacts 11 are in series with contacts 42 of a boiler water temperature regulator and a stoker switch control 43. In parallel with the contacts 11 may be contacts 44 of an intermittent "maintenance" heating plant or frost protection circuit contacts 47 which may take over when the main control is set for the lowest temperature by the action of arm 48 on rack 22 opening contacts 46. A modification is described in which the cam, operating the rack 22, is moved intermittently to alter the temperature setting to obtain heating up and shutting down and is actuated through 180 degrees at given times by a time switch controlling the current to a motor for this purpose twice in the 24 hours. In each of these examples the duration of the starting up and shutting down periods can only be altered by changing the cam. A further modification, Fig. 5 (not shown), provides means for adjusting these periods without changing any part of the mechanism, by driving the cam 27 through a clutch mechanism by a clock, there being cyclically operated means to prepare the clutch for engagement twice in each cycle, and further means performing a series of cycles during each period of,starting up or shutting down, operable to engage the clutch during a part of each of its cycles, together with adjustment to vary the duration of each part. Reference has been directed by the Comptroller to Specifications 307,376, [Class 64 (ii)], 424,833, [Group XXXVII], 446,168, and 503,957, and U.S.A. Specification 1,869,161.

Title: Variable compression ratio pistons for internal combustion engines
IPC: F02B75/04
Filed: 1972-03-18
Abstract: 1379447 Pistons; valves TELEDYNE INDUSTRIES Inc 18 March 1972 12787/72 Heading F2T and F2V In a variable compression ratio piston for an I.C. engine and having a piston shell 14 slidable on a carrier 12 and a variable volume oil chamber 30, 32 the discharge opening from the oil chamber is provided with a restricted annular oil-flow passage for filtering foreign objects from the oil. Figs. 1 and 3, shows the invention applied to the discharge opening 38, a ring member 36 being spaced from a wall 108 of an annular recess 104 to form the restricted annular oil-flow passage 114. Figs. 1 and 2, shows the invention applied to the discharge valve assembly 62, the valve casing 116 having a flange 132 spaced from a wall 122 of a bore 122 to form the restricted annular oilflow passage 130. In operation, oil is fed through the connecting rod, oil collector 50 and valve assembly 58 to the oil chamber which is divided into upper and lower chambers 30, 32. The valve assembly 58 consists of a pair of flat triangular valve plates 76 which float between valve seats 74 and castellated stop members 80, 82. During each cycle of operation, the piston shell 14 tends to move upwardly tending to expand the chamber 30 and contract the chamber 32 so that the lower valve-plate 76 closes oil to the lower chamber 32 to form an hydraulic lock between the piston shell and the carrier 14. Since, however, the discharge opening 38 permits oil to escape from the chamber 32, the piston shell will move upwardly a small distance on each engine cycle. When the gas pressure exceeds the upper limit, the discharge valve member 136 of the discharge valve assembly 62 lifts to discharge some oil from the chamber 30. This oil passes through the passages 130, 124 and 128 to act on an annular surface 143 of the valve member 136. When the oil pressure exceeds the upper limit, the valve member lifts to discharge the oil through the discharge orifice 134 in the valve seat 142 to the crankcase. The valve assemblies 58 and 62 are preferably conically-shaped for retention in bores provided in the carrier.

Title: Improvements in electric circuit breakers
IPC: H01H33/12
Filed: 1944-07-07
Abstract: 582,599. Gas-blast switches. FNGLISH ELECTRIC CO., Ltd., and ROWLAND, F. G. July 7, 1944, No. 12987. [Class 38 (v)] A pneumatically-actuated gas-blast switch is mounted together with its series isolator, in the gas-reservoir 1a defined by a barrier 4 and end cap 5 for the metal tank 1, and carrying the switch isolator respectively. The fixed nozzle contact 7a of the switch, and an arcing-tip 7b are carried on an end member 7 forming with an insulator 8 and end member 6, the circuitbreaking chamber. Member 6 has a cylinder 6a within which is a piston 9a carrying the movable contact 9 and, if desired, a valve-member 9b closing the reservoir from the breaking-chamber. Member 6 is also formed with a fixed isolatorcontact 6c with a small blast-aperture 6e, and a small port 6d. When a control-valve 12 is opened the back of piston 9a is open to atmosphere via ports 6b and pipe 11, whereby the reservoirpressures on the front of piston 9a move the latter to open position against spring action 10, the end of the stroke being cushioned by closure of ports 9b by the piston. The arc formed is transferred to the tip 7b and is in shunt with a resistance 13 connected between members 6, 7. The movable isolator - contact 19 is pivoted at 20 and connected by insulating link 24 with a piston 23 in a cylinder 22, the ends of which are connected by pipes 25, 26 to valve 12 and by smaller pipes 22a, 22b to the reservoir. The pipes 25, 26 are chosen to ensure movement of piston 22 after the piston 9a, this movement being effected by exhausting the rear of the piston to atmosphere. When valve 12 is restored, air enters port 6d to equalize the pressures on the piston 9a, which is returned to closed position by spring 10. The pipe 22b also enables the pressures on piston 23 to be equalized, reclosure of the isolator being effected by exhausting the front of the piston. Valve 9b may be dispensed with, and the end of the silencer 14 may instead be closed by a valve opened simultaneously with valve 12, the break thus occurring in a pressure-atmosphere. The valve 18 may be opened by the air-pressure or by an electromagnet. Piston 23 may also operate, by means of shaft 35, auxiliary switches in a pocket 5a in the cap 5, access being had thereto by removing a cover 33. The blade 19 may have a snap-action spring, and may be replaced by a rotary or rectilinearly-moving member with a small bore therein to pass a blast of air, the contact being of the plug-and-socket, or knifeblade type. The movable isolator contact may be arranged on the end 6 of a second gas-blast switch mounted in plate 5 and oppositely-directed to the one in barrier 4. The arrangement of lead-in contacts 27, 30 is such that the two switches may readily be removed. The Provisional Specification states also that one or a pair of current transformers may be provided in the lead-in conductor or conductors, either within or outside the tank.

In one embodiment, Fig. 1, the workpiece 46 is mounted between a fixed holder 27 engaging a centring hole in the workpiece 46 and a holder 30 moved by a jack 32 to engage a centring hole in the opposite end of the workpiece 46. The die 28, mounted on a framework 13-16, is moved over the workpiece 46 to produce a splined article by the piston-rod 42 of the jack 40. During deformation the workpiece holder 30 is moved to the left by the elongating workpiece, the pressure in the jack 32 being maintained constant by a check valve 36. In another embodiment, Fig. 4, the workpiece (not shown), is first positioned between a die 67 mounted on a die holder 60 connected to a ram 59 of an hydraulic jack 57 and a die 68 mounted on a die holder 65 connected by rods 63, 64 to a plate 58 which is connected to the movable jack cylinder 57. Hydraulic fluid is supplied to a jack 75 and the right hand side of the cylinder 57 to cause a workpiece holder 71 connected to the ram of the jack 75 to force the workpiece against the die 67 and thereafter the die 68 against the left hand end of the workpiece. Subsequently, the workpiece is extruded by the holder 71 through the die 67 until it engages a fixed holder 66 fixed to the die holder 60. During extrusion the pressure in the cylinder 75 is maintained constant by a check valve (CV) (Fig. 11, not shown). Upon further movement of the cylinder 57, the die 68 is moved over the workpiece and the workpiece holder 71 moved to the left by the elongating workpiece, the pressure in the cylinder 75 being maintained constant by the check valve (CV). After deformation of the workpiece has been completed, the components are returned to their initial positions by delivering fluid to the left hand side of the cylinder 57.
