Title: Improvements relating to the protection of cathodes of thermionic valves
IPC: H03F1/54
Filed: 1932-01-11
Abstract: 397,154. Converting. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Morack, M. M. ; 900, Union Street, Schenectady, New York, U.S.A.) Jan. 11, 1932, No. 16579/33. Convention date, Jan. 10, 1931. Divided on 395,344. [Class 38 (ii).] Full current flow is prevented through valves having thermionic cathodes until the cathodes, after the application of the operating potentials, have reached their operating temperatures. For this purpose the bias on the grid of a valve is removed or made ineffective by means depending on the heating up of a device thermally comparable with the cathode. In the system shown in Fig. 1, a balanced Wheatstone bridge 61 .. 64, with arms unequally affected thermally, on sufficient heating becomes unbalanced and an A.C. potential is superposed on the D.C. potential from the battery 60. In Fig. 2 (not shown), the phase of an alternating potential obtained from an impedance phase shifting device is altered by means of a thermal device which short-circuits a part of the impedance device. In an inverter, Fig. 3 (not shown), zero bias on the grids is replaced by a positive bias when a thermal device responds to connect a condenser in the grid circuit across the D.C. supply. Specification 353,203 is referred to. Reference has been directed by the Comptroller to Specifications 199,016 and 202,294, [both in Class 40 (v), Wireless signalling &c.].

Title: Sludge treatment
Inventor: JOHNSON PETER FREDERICK
IPC: C02F11/121
Filed: 1968-04-08
Abstract: 1,270,803. Sewage sludge settling. DORR-OLIVER CO. Ltd. 15 April, 1969 [8 April, 1968], No. 16818/68. Heading B1D. A settling tank is divided by wedge wire partition 7 into compartments 2, 3 into which sewage sludge and water are respectively fed at rates which ensure their levels rise at the same speed. After settling, the sludge forms alternate bands of water and thickened sludge, and water is slowly withdrawn from compartment 3 together with settled water, which flows through partition 7 while sludge remains behind. After the bands of water in compartment 2 have vanished, sludge and water are withdrawn from respective compartments at controlled rates, maintaining a small differential level by detector 13 .. 15 which controls one or both pumps 11, 12. Pump 12 is reversible and used to feed water into compartment 3 as well as to withdraw it. During filling, pump 12 starts a short time before pump 11. The valves shown are set to ensure desired flow rates. Gravity feed and discharge, controlled by powered valves, could replace the pumps. Flocculating agent may be added with the sludge to compartment 2. In Figs. 2, 3 (not shown) there are four compartments 3 in the corners of a tank which has rotary floor scrapers (18). The wedge wires are vertically oriented, broad side to the sludge. Partition 7, in Fig. 1, slopes at 5 to 10 degrees to vertical to prevent sludge sticking thereto. The liquid introduced into compartment 3 may differ from the sludge liquid, oil being suitable. Partition 7 could define tubes of square, triangular or circular section instead of flat walls. Sump (17) in Figs. 2, 3 could be centrally located.

Title: Improvements in or relating to moulds for the production of composite panels or the like, sheets or structures containing veneer or plywood
IPC: B27D1/08
Filed: 1942-12-01
Abstract: 562,012. Moulding wood. KING, E. P., and WOOD DEVELOPMENT, Ltd.. Dec. 1, 1942, No. 17100. [Class 145 (ii)] [Also in Group VIII] A mould, for the production by fluid pressure of sheets or structures containing veneer or plywood, comprises a primary member and a secondary flexible member between which the plywood is built up and shaped, the primary member being a hollow structure having a thin mould shell which is rigid compared with the flexible member and is impervious to the pressure medium. The primary former may be a skeleton structure or framing 10, Fig. 1, of wood, metal, or reinforced plaster, to which a thin mould shell 12 of plywood or sheet metal is attached. The secondary former consists of an inner layer 14, Fig. 2, of fine hessian, fabric, or wire .gauze with an outer impervious covering of natural or synthetic rubber, regenerated cellulose, artificial resins, heat and moisture-proofed fabric, then plywood, or thin ductile metal sheet. This former is clamped or otherwise secured to the primary former along marginal stiffening strips 11 to form an air-tight seal. Layers 13 of plywood are built up on the shell 12, and when the flexible member has been applied and fastened along the strip 11, the plywood 13 is pressed by exhausting air from between the members and, if desired, placing the whole structure in an autoclave where it is subjected to heat and additional pressure. The construction allows both surfaces of the mould to be subjected to the same pressure. Fig. 4 shows the device used for making a cellular structure 13, and in this case a packing strip 17 of yieldable material, such as soft rubber, is provided between the edge of the flexible member and the strip 11. The shell 12 may be shaped by moulding it in an autoclave on a master mould, so that a number of shells of identical contour can be made. Specifications 559,527 and 559,528 are referred to.

Patent GB-575099-A (GB)
Title: Improvement in or relating to internal combustion engines
IPC: F02B75/10
Filed: 1943-10-18
Abstract: 575,099. Arrangement of sparking- plugs. FOWLER, G. B., and TOEWS, G. P. Oct. 18, 1943, No. 17118. Convention date, April 10, 1943. [Class 7 (ii)] An internal-combustion engine has at least three spark-plugs in each cylinder, two being located at positions 1, 2, Fig. 1, between the inlet valve I and exhaust valve E, while at least one of the others is located at 3 near the inlet valve and is independently controlled as to its time of firing. The plug 3 is fired slightly before the other two. By this arrangement, three flame fronts are obtained and the final combustion usually accompanied by some detonation occurs at the central part of the cylinder as shown by cross-hatched area. In the normal arrangement with two opposed plugs per cylinder, Fig. 4, the flame fronts which are distorted as shown by the influence of the hot exhaust valve, result in a final combustion area located at the side of the cylinder. The invention may also be applied to combustion heads having four valves, Fig. 2, the opposed plugs 1 and 2 being as before fired simultaneously and the plug 3, located between the inlet valves 1 being fired slightly before the other two. The plugs may be arranged in the head of the combustion chamber instead of in the side as shown in Fig. 2, or the plug 3 only may be in the side. In one embodiment, Fig. 7, an engine having three plugs per cylinder arranged as above described has independent magnetos M<1> ... M<3>, each with its own timing control, for the three sets of plugs. In the case of an engine provided with two plugs located as in Fig. 5, two additional plugs making four in all would be required to obtain a single detonation area near the centre of the head. In order to accommodate the three plugs, the head is preferably of flat type (Fig. 1a). The invention enables a compression ratio of 14 : 1 to be used, giving increased power with decreased fuel consumption per b.h.p./hour.

Apparatus for travelling coated interior surfaces of a pipe &c. 15, has a substantially frustoconical trowelling element 17 formed of one or more leaves, the longitudinal edges of which circumferentially slidably overlap, the larger end of the element being adapted to engage under pressure and to smooth the pipe coating, and a yieldable assembly for applying radially outward pressure to the interior surfaces of element 17 at locations around and within the trailing end thereof through anti-friction elements 31. The yieldable assembly may, as shown, consist of springs 21 mounted in spaced radical planes and anchored at their ends to spaced discs 22, 23. The latter are movable, on a central rod 24, relative to a fixed central member 25, by screws 26 rotated by handle 28 and such movement adjusts the pressure exerted on the element 17 by the anti-friction members 31. The forward end of element 17 is enclosed by housing 36 to prevent the ingress of foreign matter and has means for securing it to means for dragging the element through the pipe. In a further embodiment (Fig. 6, not shown) the leading end of the element 17 has support means which permit sliding of the element 17 relative thereto so as to constrict or expand the frustoconical element. With this embodiment the member 25 (Fig. 1) is adjustable along rod 24 so as to position the yieldable means in its optimum position. In a further embodiment the forward ends of springs 21 may be secured to the front housing 36.

Title: Improvements in or relating to pneumatic tube conveyors
IPC: B65G51/32
Filed: 1932-06-17
Abstract: 403,386. Pneumatic dispatch apparatus. KRIEGER, L., 120, Avenue d'Orleans, Paris. June 17, 1932, No. 17222. Convention date, July 31, 1931. [Class 116.] In a pneumatic dispatch apparatus, a device permitting a carrier to proceed in its original circuit or to be switched into a branch which may be either a receiving station or a circuit in which the pressure is higher or lower than that in the main circuit, comprises a pivoted deflecting-member which is traversed by the carrier in a direction from its pivot to its tip, means for moving the member into one of its two settings, and means for holding it in the deflecting-setting, so that the impact of the object does not tend to move the actuating means of the deflecting-member into the other setting. Fig. 1 shows a form for use when the pressure in the main circuit 1 is higher than atmospheric and the branch 12 leads to a receiving station. When the carrier is to be switched, a deflecting-member 2 pivoted to a lever 5 of a toggle - device 5, 6 is brought into the positions shown in full lines by the energisation of an electro-magnet 11, the impact of the carrier tending to move the hinge of the members 5, 6 further to the left, which movement is limited by a stop 9. The carrier then strikes the tail of a small flap 17 pivoted to a pivoted flap 13 serving to isolate the circuit 1 from the branch 12, and the pressures on either side of the flap 13 are equalized so that the flap 13 may be opened by the carrier. As the flap 13 is opened, contacts 26, 27 are operated to de-energise the electromagnet 11 and permit the associated parts to assume the dotted-line positions under the weight of the falling core 10, thus allowing a closely-following carrier to continue in the circuit 1, if so assigned. The carrier within the branch 12 then strikes the tail 22 of a further pivoted flap 21 whereby the branch 12 is placed in communication with the atmosphere thus facilitating the opening of an outlet flap 20 by the carrier. The pressure in the branch 12 being diminished, the flap 13 closes under the action of a piston 15 of larger area than that of the flap, the associated cylinder 14 communicating with the air-circuit 1. Another form is described in which the branch leads to a second circuit in which the pressure is higher than that in the original circuit.
