Title: Improvements in or relating to puffed dough products
Inventor: BAER JOHN MARTIN
IPC: A23L1/18
Filed: 1953-09-22
Abstract: In making cold-set, puffed, granular dough products, moist dough granules are gradient-dried until they acquire a relatively brittle outer shell, the dried granules are pressure-cooked in steam, which raises the moisture content of their shells, but does not bring it above that of their interiors, and are then shot into an evacuated chamber.  Air may be removed from the granules between drying and cooking, e.g. by subjecting them to reduced pressure.  The moist dough granules may be dried in a flame-heated atmosphere, having a temperature between 350 DEG  and 400 DEG  F., until their surface temperature is between 270 DEG  and 280 DEG  F.  The granules may be dried in a rotating screen over two banks of gas burners and just out of contact with the flames.  Specifications 530,157 and 675,292 are referred to.

Title: Fluid pressure operated valve assembly
IPC: F16K17/10
Filed: 1966-06-14
Abstract: 1,144,584. Valves. WILLIS OIL TOOL CO. 14 June, 1966 [5 April, 1966], No. 26474/66. Heading F2V. [Also in Division G3] A pilot-operated valve suitable for controlling the output of an oil well is adapted to close in response to predetermined high or low pressures at its downstream side. As shown, the valve has an inlet 13, outlet 16, main closure member MV integral with a piston 21 working in a cylinder 20, and a pilot valve PV controlling communication between the space above piston 21 and pilot chamber 33, the latter communicating with the valve inlet via passages 40-42 and 44. Outlet pressure acts via passage 118 on one side of a piston (117, Fig. 4, not shown) working in a cylinder (116), the piston serving to transmit the outlet pressure to a chamber 82 (Fig. 2b) via a fluid link in a line 82a. Fluid pressure in chamber 82 acts on opposed pistons 83, 86 which contact respective spring-loaded sleeves 66, 98 having lost motion connections with the pilot valve stem 60. The pilot valve is pressurebalanced in its closed position and if the outlet pressure falls below a predetermined value, spring 68 moves sleeve 66 upwardly to unseat the pilot valve to close the main valve. After its initial unseating, the pilot valve is no longer pressure balanced and is urged rapidly upwardly to abut a guide 35. The sleeve 66 continues its upward movement until it abuts a surface 81 of housing 77. If, on the other hand, the outlet pressure rises above a predetermined value, piston 86 moves upwardly against spring 93 to cause sleeve 98 to engage stem 60 to unseat the pilot valve. As before, after the pilot valve is initially unseated it is urged rapidly upwardly by pressure in chamber 33 to abut guide 35, and the sleeve 98 continues its upward movement until it abuts a flange 101. To reset the valve, valves 130 and 131 are respectively closed and opened. The pilot valve may be opened manually by rotating a cap 105 having a threaded connection with a stationary plug 102. In Fig. 6, not shown, sleeve 98 &c. is removed so that the valve will only close in response to a predetermined low pressure. In Fig. 7, not shown, the outlet pressure is sensed downstream of a choke and is transmitted to chamber 82 either directly or via the fluid link comprising piston (117) and line 82a.

Slots 14 and links 18 on the front cover are preferably longer than slots 15 and links 19, and the end walls 11 are upwardly tapered. The covers are hinged below the level of the slots 14, 15 so that the weight of the covers pushes the studs 20 into slots 16. The end walls 11 are formed with an inner flange 22 to engage notches 25 in the edges of flexible partitions 23, the partitions being held in position in notches 13 under the flanges 22. The tray 1 is supported on end plates 4 and to steady the tray in use, a flat bar (not shown) is pivoted to the underside of the tray between the plates 4 and can be turned crosswise of the tray to brace it laterally. A portion of the metal covers may be punched out and rolled over to form handles for carrying the device.

Abstract: 1,076,003. Making grid electrodes. COMPAGNIE FRANCAISE DE TELEVISION. June 23, 1965 [June 25, 1964], No. 26678/65. Headings B3A and B3E. A method of making a flat grid for a cathoderay tube comprises the steps of winding a wire about two parallel grooved winding rods 2 to form two parallel sheets of wires, tensioning the sheets of wires over parallel positioning rods 14 to form a single sheet of wires which can be fastened to a grid frame 9, the surplus wire outside the grid frame then being trimmed off. The winding rods 2 are mounted on channel members 1 which can be rotated about a shaft 4, Fig. 1, to make the winding. This assembly is thon placed in a mounting frame 12 to which it is fixed by bolts passing through holes 5, Fig. 1. The wires then pass over the grooved positioning rods 14 and are tensioned by further rods 18 which are forced downwards by screws 22. The grid frame which rests on screws 15 is then raised by means of these screws until it is close to, but not necessarily touching, the wires and sealed to the wires by any conventional method. A preferred method consists in depositing enamel 23 on the wires and fusing the enamel in a furnace, electrical connection to the wires being ensured by a metallized layer (24, Fig. 6). Sealing by this method has the advantage that the sheet remains plane even if the grid frame is not flat (Fig. 6). In order to avoid a difference in tension in the wires when the surplus wire is cut away the grid frame 9 may be pre-stressed by means of a rod (10, Fig. 2) which is removed after sealing the wires to the grid frame.

In a subscriber trunk dialling system, means are provided for permitting a PABX subscriber to have a call up to a predetermined but variable maximum charge before he is cut off. When a call is made from a PABX extension EXT to the main exchange over the line shown, the exchange line circuit EL is seized and by applying earth to the hold lead H, operates relay G. A transformer TR1 is connected in simplex via condensers C1 and C2 to the line so that upon receipt of metering impulses, relay M will operate in response to each pulse. Consequently uniselector LS is stepped once per pulse until a marked contact (the fourth as described) on one bank of the uniselector is reached. Hence relay B pulls up and by opening lead H, causes the call to be released. When the exchange line circuit is cleared G releases and closes a homing circuit for the uniselector.
