Title: Improvements in electrical switches
IPC: H05B1/02
Filed: 1966-04-13
Abstract: 1,148,281. Thermal switches. ROBERTSHAW CONTROLS CO. 13 April, 1966 [13 April, 1965], No. 16200/66. Heading H1N. [Also in Division H2] A switch comprises a first lever pivoted intermediate its ends, a second contact-carrying lever coupled to the first to one side of the pivot so as to be rotatable relative to the first, a first spring coupling between the levers on the other side of the pivot and a spring or magnet opposing the first spring. Normally, when the first lever is moved towards the second, the bias of the spring or magnet is overcome and the contacts open, but if they weld the first spring yields to allow endwise movement of the second lever to shear the weld. In one form, contact lever 62 is coupled at its upper end to a lever 53 pivoted at 54, the levers being separated by a spring 68 and loosely coupled at 64, 66. When actuator 24 moves to the right, biasing spring 82 is overcome and contacts 76 open. If a weld occurs, the coupling 58, 61 between the levers lifts lever 62 to slide the moving contact across the fixed. The second lever may carry two bridging contacts (Figs. 8, 9, not shown), and spring 82 may be replaced by, (Fig. 12, not shown), or augmented by (Fig. 14, not shown), a magnet (114), (144). The coupling spring (140) between the levers may act on a further lever (137) in turn acting on the second lever. The switch is preferably activated by thermal means, e.g. a fluid-filled capsule.

Title: A process and apparatus for treating food products
IPC: A23L3/10
Filed: 1963-04-25
Abstract: 1,036,626. Preserving food. INDUSTRIE VERWERTUNGS PRODUKTE ANSTALT. April 25, 1963 [Nov. 30, 1962], No. 16412/63. Heading A2D. Food products packaged within hermetically sealed thin-walled containers of heat-conducting material (aluminium or plastic material) are sterilized by heating the containers in an autoclave by a hot fluid (steam), simultaneously increasing the pressure within the autoclave by a pressurized fluid (compressed air) to balance any increase of pressure within the containers (the hot fluid and pressurized fluid being maintained respectively at the sterilizing temperature and at the corresponding pressure for a period of time sufficient to sterilize the contents of the containers),and refrigerating the sterilized containers by a cold fluid and gradually discharging the pressurized fluid to balance the decrease of pressure within the containers. There may be introduced into the autoclave a gas which is a catalyst for polymerizing the substance forming the sealing packing of the containers, steam and water. The hot or cold fluid (as the case may be) is passed through horizontal copper ducts located between movable shelves supporting the top and bottom surfaces of the containers. The shelves may have recesses for accommodating the containers. It is acknowledged that the ducts could be replaced by electrically heated plates or, in part, by irradiation heating apparatus.

Patent GB-446711-A (GB)
Title: A process for the production of cracked gasoline having low gum content
IPC: C10G9/36
Filed: 1935-06-06
Abstract: In processes for cracking oils by direct contact with hot carrier gases, e.g. as described in Specification 367,728 the proportion of gum content in the gasoline obtained is reduced by admitting cooled carrier gas to the rectification stage in such proportions that the gasoline in the rectifying zone, if liquid, would vaporize at a temperature at least 100 DEG  F. below its atmospheric boiling point while products heavier than the gasoline are condensed and separated. Crude oil from a tank 10 is led into a scrubber 12 and the vapours produced are rectified in a column 14.  The condensate <PICT:0446711/III/1> obtained is led through a line 16 to vaporizing, flashing and superheating zones 17, 18, 19 and the vapours produced are cracked in a reaction chamber 20 by contact with hot carrier gases from stoves 22.  The products then pass to the scrubber and rectifier 12, 14 where rectification conditions are controlled by introducing the required amount of carrier gas, heated in a heat-exchanger 30 to 500 DEG  F., through pipes 32, 33.  Gasoline vapours are led off through condensers 35, 36, and scrubber 37 to a separator 39 where the carrier gas is separated and recirculated to the stoves 22 and as required to the exchanger 30. Specification 317,508, [Class 32], also is referred to.

Title: Electrical switch controlling devices, in particular for controlling deicing apparatus for gas turbine jet propulsion engines
IPC: F02C7/047
Filed: 1955-06-09
Abstract: 771,153. Gas turbine plant. LEIGH, L. P. June 9, 1955, No. 16560/55. Class 110 (3). [Also in Groups XIII and XXXVII] Two pressure - sensitive switches S are arranged in the air intake 15 of a gas turbine engine so as to cause operation of de-icing apparatus if icing occurs. Each switch (see Group XXXVII) has a tube 34 with a horizontal portion in the intake and a vertical portion supporting a ball 37. Normally, the ball is held in the raised position shown to hold the switch contacts open by the air entering the horizontal portion. If ice forms on a cap 39 on the tube, the ball drops and the switch closes to energize a solenoid or similar device 28 to open a valve in a pipe 22 so that hot gases from the turbine 18 pass to a heat-exchange unit H (see Group XIII) where air passing through a tube 29 from an intake 31 is heated. This hot air is fed into the intake 15 by a diffuser D having rearwardly facing holes. It is stated that the ball 37 is rotated at low speeds, i.e. below 400 m.p.h. by the different air pressures existing on opposite sides of the vertical axis of the tube 34, this rotation causing any moisture deposited on the ball from the air to be blown out of the vent 38 in the cap 36 of the tube so that the ball will not freeze in its upper position. At higher air speeds, the ball may not rotate but the air pressure around the ball increases and so raises the temperature of the air, thereby preventing icing of the ball.

Title: Improvement in electromagnetic brakes
IPC: F16D55/28
Filed: 1942-11-25
Abstract: 561,776. Electrically-operated brakes. IGRANIC ELECTRIC CO., Ltd. Nov. 25, 1942, No. 16721. Convention date, Nov. 28, 1941. [Class 103 (i)] In a spring - applied electro magnetically released disc brake, the magnet with a non- rotatable friction disc and the application spring are removable as a unit. Hand release of the brake and adjustment of the spring pressure is effected by a single lever. Adjusting means for the non- rotatable friction disc relatively to the armature to compensate for wear are provided. As shown, the disc 11 is slidably connected by pins 17 to a hub 4 keyed to the shaft 5 of an electric motor and is arranged to be gripped between a mounting plate 1 bolted to the motor housing 2 and a non-rotatable disc 9 by the pressure of a spring 10 that bears on the armature 8 of a magnet comprising a coil 7 and field members 6, 21. The magnet is provided with a shrunk-on annular member 18 of non-magnetic material by which it is mounted on the plate 1, by screws 19. The disc 9 and armature 8 are slidable on pins 23 fixed in the member 21 and the armature bears on the disc through a nut 26 which can be turned to adjust the disc 9 to compensate for wear of the friction linings 12. The disc 9 is returned when the magnet is de-energized, by a spring 49 which, at one end bears on the end 51 of the pin 48 and at the other end is fixed to the end 33 of a stem 31. This end of the stem is squared so that the nut can be turned with the stem by a tool applied to the outer end 37. A hand lever 32 slidable against the action of a spring 43 on a pin 41 screwed into a cylindrical projection 28 on the magnet is slotted to receive the squared part 36 of the stem 31 and has a pair of pins 39 one above and one below the stem, which engage a slot 40 in the nut 30 upon which the spring 10 bears. The lever may thus be fulcrumed at its upper end on the projection 28 to the broken line position to effect manual release of the brake by engaging a collar 38 on the stem 31 or by removing the screw 41 and sliding the lever downwards so that a circular part of the slot therein surrounds the stem, the lever may be turned about the stem to adjust the nut 30 and thus the compression of the spring 10. After this adjustment has been made, the pin 41 can be inserted in another hole in the projection 28, to secure the lever in the new position. Upon removal of the screws 19 the magnet with its armature 8, the disc 9 and the spring 10 may be dismounted from the plate 1. A housing 53 for the electrical connections of the magnet is provided.
