Title: Improvements in and relating to pasteurization apparatus for liquids in bottles, tins and similar containers
IPC: A23L3/00
Filed: 1940-06-14
Abstract: 544,032. Step-by-step conveyers. NYEBOE & NISSEN AKTIESELSKABET. June 14, 1940, No. 10390. [Class 78 (i)] Containers are passed step-by-step through a pasteurization apparatus by intermeshing grid platforms 96, 98 reciprocating relatively to one another. The platforms are carried on carriages 14, 17 riding on wheels 86, 87 running on rails 89, inclines 88 being located on the rails 89 in front of the wheels 86 so that the platform 96 rises and falls during its reciprocation and lifts and deposits the containers off and on the platform 98 at different locations of the latter, thus gradually advancing the positions of the containers and traversing them through the apparatus. The platforms and carriages may be suspended by links instead of running on rails. Two sets of platforms may be provided, located one above the other, and having the upper and lower corresponding members connected by uprights 90, 91, but one, or more than two, platforms may be used. Reciprocating motion is imparted to the carriages 14, 17 by connecting rods 85, 84 coupling them to bell-cranks 80, 81 rocked by eccentrics 13, 16 on a shaft 10 operated from a power shaft through equal-sized pinions, that on the power shaft having half its teeth removed so that it imparts intermittent half-turns to the shaft 10. The stroke of rod 84 is adjustable. Driven through gearing from the power shaft is an endless-belt conveyer 74 extending across the entry end of the apparatus at the level of the lower platforms, and between the conveyer and the platforms is an elevator 32 adapted to be raised and lowered from one set of platforms to the other by rods hinged to cranks on the ends of the shaft 10. Beneath the elevator 32 is a bridge 73 raised by cams to follow the elevator 32 as far as the level.of the conveyer 74, and to drop with the elevator when this returns. Cam-operated flanges rise and fall at appropriate times on each side of the elevator 32 and bridge 73. In action, a batch of containers is brought by the conveyer 74 opposite the entrance to the pasteurizing chamber, and is pushed laterally by a camoperated rocker on to the elevator 32. This is then raised and the upper end of the rocker pushes the containers on to the upper platforms 96, 98, the whole rocker being moved forward so that its lower end pushes also a batch of containers newly arrived on the conveyer 74 on to the bridge 73 and thence on to the lower platforms 96, 98. A similar device may be furnished at the delivery end of the chamber to remove the containers.

Title: Improvements relating to vent valves
Inventor: BOSWELL ARTHUR CHARLES
IPC: F16K39/02
Filed: 1952-04-25
Abstract: 708,693. VaLves. ENGLISH ELECTRIC CO., Ltd. April 17, 1953 [April 25, 1952], No. 10454/52. Class 135 In a vent valve for an aircraft fuel tank, the depression acting on the valve body 13 due to the movement of the aircraft is balanced by allowing the same pressure to act in an opposite sense on a pressure-responsive member (diaphragm 21) connected to the valve body, and the valve is opened against a resilient biasing force (e.g. spring 14) when the internal pressure in the tank acting on a second pressure-responsive member (diaphragm 17) differs by a predetermined amount from the static air pressure acting on diaphragm 17 in the opposite sense. As shown, the tank fits flush with the skin 11 of the aeroplane and the aero-dynamic pressure has access to the valve body through an opening 15a and to the underside of diaphragm 21 through a bore 16 in the valve stem. The vapour in the tank has access to the top of diaphragm 17 through openings 10e whilst static air pressure is applied to the space between the two diaphragms through a passage 23b. In modifications ,the valve body opens inwardly, and by varying the relative areas of the diaphragms, the valve will function to maintain the pressure in the tank lower than the aero-dynamic pressure. The simple compression spring 14 may be replaced by a pair of compensating telescopic springs. The temperature in the valve is maintained by an electrical heater in the space 12f surrounding the flow passage, the supply leads for the heater entering at 24.

Title: Improvements relating to valves or cocks
IPC: F16K5/22
Filed: 1931-04-10
Abstract: 370,190. Lubricating valves. LEACH, R. W., of Audley Engineering Co., Ltd., Newport, Shropshire. April 10, 1931, No. 10592. [Classes 12 (ii) and 12 (iii).] A plug cock has a lubricant reservoir f adj acent to one end of the plug d fitted with a piston g working in a cylindrical cavity in said end of the plug and subject to the pressure of the controlled fluid and the action of a spring j so as to exert pressure on the lubricant in said reservoir and channels m leading to the working surfaces, in excess of that of the controlled fluid. The latter has access to the cylindrical cavity through a hole h. When the cock is closed, a lateral hole y enables the controlled fluid to reach the main passage i, and the cylindrical cavity. A plate or cross-piece k secured to the outer end of the piston g forms one abutment for the spring j, the other being formed by the plug d itself as in the Figure, or by a plate resting on a shoulder in the casing a. Excess lubri-: cant may escape into the cock'when the holes u, v in the plug and piston respectively coincide. Stepped circumferential and longitudinal channels m completely surround the fluid passage. The former may be in the casing a and the latter in the plug d, or their positions may be reversed as in the Figure. An actuating stem n may be formed integrally with the plug d or separately as in the Figure. In the latter case, a tongue q on one member engages a slot r in the other. Alternatively an Oldham coupling member may be interposed between the plug and actuating spindle. Lubricant may be forced past a non-return valve p in the stem n by the screw o or forced into the reservoir f by a grease gun applied to a nipple containing a non-return valve shown at x. The reservoir f may be formed integrally with the casing a or by a cap e screwed thereto. Leakage past the stem n may be prevented by packing rings s as shown in the Figure, or by a screw connection. In a modification the lubricant reservior f is below the plug d which is in this case supported by an additional spring.

The switching arrangement comprises a relay 15 having contacts a1-a7 which changeover from the positions shown in the figure when a switch 19 is closed. The connecting of the contacts a2, a6 enables the mechanism 18 to trigger the thyristor 10 thereby discharging the condensers 11 through the welding circuit including the welding gun 16 and a workpiece 17. Opening of the switch 19 de-energizes the relay and connection is established between the contacts a2, a5 to cause the mechanism 18 to switch off the thyristor 10. If the thyristor does not become non-conductive, the condensers 11 discharge through the thyristor 10 and the closed contacts a3, a7 whilst the closed contacts a1, a4, the thyristor 10 and the closed contacts a3, a7 short circuit the output of the rectifier bridge 6 to blow a fuse 2. Modifications of the circuit are described in which the transformer 1 is replaced by a current limiting stray field transformer and in which an additional thyristor is located in the short circuit path across the rectifier output. A circuit is also described in which the additional thyristor is triggered by a Zener diode to prevent an excessive voltage appearing across the condensers 11.
