Title: Hydraulic Clamping Mechanism for Injection Moulding Machines
Inventor: STUEBBE FRIEDRICH
IPC: B29C45/76
Filed: 1967-03-21
Abstract: 1,182,456. Injection mould closing devices. F. STUBBE. 21 March, 1967 [23 March, 1966], No. 13103/67. Heading B5A. A mould closing plate 15 is connected by a tubular piston-rod 14 to a double-acting annular piston 12 slidable between concentric cylinders 11, 13 to define chambers 5, 7, the latter storing hydraulic fluid displaced by the piston during rightward mould opening movement, the stored fluid being used to supplement the supply of fluid to the other side 4 of the piston during a mould closing movement. An arrangement of electrically operated solenoid valves (S 1 -S 5 ), a non-return valve (R), a throttle (D), a contact pressure gauge (Ma) and a reservoir (R1), (Fig. 2, not shown), form part of a circuit for supplying fluid from a low pressure source (ND) to effect a mould closing movement. Actuation of a limit switch (E1) when the mould is closed, cancels the low pressure side of the circuit and connects a high pressure part (HD) to the side 4 of the piston, to effect a clamping action on the mould parts, the annular chambers 5, 7 being connected to the reservoir (R1), the valve (R) holding pressure on the side 4. To open the mould, the valve (R) is opened and the chamber 5 is connected to the source (ND), the piston moves rightwardly and oil passes from the side 4 to the chamber 7.

Title: A steam generator and method of operating the same
IPC: F22B21/34
Filed: 1956-04-30
Abstract: 802,032. Regulating steam temperature in boilers. COMBUSTION ENGINEERING Inc. April 30, 1956 [June 20, 1955], No. 13159/56. Class 123(3) A water-tube steam boiler comprises a furnace 14 lined with steam generating tubes 16 and fired by tilting burners 18, combustion gases flowing from the furnace outlet 20 through a pass 22 locating a secondary superheater 32, a reheater 42, a primary superheater 30, an economizer 62 and air heater 64. To maintain optimum steam temperatures over a wide load range of the unit flue gases are withdrawn from a zone upstream of the superheater 30 through a duct 46 in which is disposed an auxiliary reheater 44 serially connected to the reheater 42, the flue gas by-passing the superheater 30 and passing to a fan 48 which delivers it through a duct 52 to the lower part of the furnace 14. At full load the unit is designed to deliver steam at optimum superheat and reheat temperatures. As the load decreases, gas is recirculated at an increasing rate to maintain the superheat temperature, the increasing gas flow past the auxiliary reheater 44 serving automatically to counteract the tendency for the reheat temperature to fall more quickly than the superheat temperature under conditions of decreasing load. Adjustment of the tilt of the burners 18 serves to vary the temperature of the superheated and reheated steam relative to each other independently of the gas recirculation control, if this becomes necessary, for example, because of fouling of the heat exchange surfaces.

Title: A high-tension electrical insulator
IPC: H01B17/38
Filed: 1961-04-12
Abstract: 940,036. Insulators. SIEMENS-SCHUCKERTWERKE A.G. April 12, 1961 [April 12, 1960; March 28, 1961], No. 13239/61. Heading H2C. A pin-type insulator is surrounded by a reinforcing collar 2 having apertures 12 and cemented at 4, the lower edges of the cement, the collar, and the cement fixing for the pin all lying in the same horizontal plane. The insulator body 10 is preferably formed with the two areas 8, 9 of universal thickness so that when an electrical overload causes break-up of the insulator, either the cap or foot will break away leaving the central body 10 fixed to the pin 3 within the collar 2. Pockets of excessive pressure built up within the central portion may disperse through the apertures 12. A resilient insert 5 at the head of the pin 3 may be made from quartz fabric, lead, or " Teflon " (Registered Trade Mark). The reinforcing collar may extend partially over the top face of the insulator and have fixing lugs attached. The space between the collar and the insulator may be filled with an insert of asbestos, quartz fabric or mica, instead of cement. The apertures 12 may be interconnected by a channel in the inner surface of the collar 2, the channel being covered by a thin metallic foil to prevent ingress of the fixing cement. When the insulator is adapted for horizontal use (Fig. 4, not shown) the uppermost aperture extends axially from the interconnecting channel rather than radially as in the case of the other apertures.

Filed: 1967-03-22
Abstract: 1,207,153. Respiratory appliances. WALTER KIDDE CO. Ltd. 15 Feb., 1968 [22 March, 1967], No. 13556/67. Heading A5T. Apparatus for regulating the gas supply pressure to a plurality of face masks and operating pressure-responsive latch means to open mask retaining means for releasing the masks for use comprises first and second lines 28, 29 'between an inlet 22 and an outlet, a surge valve 31 in the first line 28 which is opened when ambient pressure falls below a predetermined amount to provide a pressure pulse for opening the latch, a valve 38 closing the first line 28 after a ,short period to terminate the pressure pulse and a main supply valve 45 in the second line 29. Gas entering the device is controlled by a pressure reducing valve 24. The surge valve, which comprises a diaphragm 32 and a seat 33 and ,is normally closed, is controlled by a normally open check valve 36 in a bleed line 35 connecting a control chamber 34 of the surge valve with the heat pressure line 28. At a predetermined low ambient pressure an aneroid 37 closes the check valve 36 and opens a vent in the bleed line so that pressure in the surge valve control chamber is reduced and the surge valve passes a pressure pulse via the closure valve 38 to the outlet. The closure valve 38 which also comprises a diaphragm 41 and a seat 39 is opened by the pulse against the pressure in its control chamber but closes when the pressure in its control chamber has built up under the control of a needle valve 44. The main supply valve, which is operated by a diaphragm 47, is controlled by the pressure ,in a chamber 48 which is normally supplied with gas from the second line 29 through a bleed line 49 and a needle valve 52 and is vented through a passage 51 controlled by a needle valve 54 which may be controlled by a spring-urged piston 57 or adjustably fixed (Fig. 3). Normally gas escapes from the chamber 48 at a rate greater than it enters so that the supply valve is closed. Under the control of an aneroid 53, the needle valve 52 permits an increase of gas flow to the chamber 48 with decrease of ambient pressure so that the main supply valve 45 opens. The needle valve 54 may be operated by the piston 57 which tends to close the valve against the supply pressure communicated to it through a conduit 62. On increased demand, the needle valve 54 tends to close the vent 51 so that the pressures of gas in the chamber 48 and passing through the supply valve increase. A manual override needle valve 55 permits the chamber 48 to be disconnected from the vent so that the main supply valve opens.
