IPC: F02B27/04
Filed: 1936-07-17
Abstract: 478,576. Exhaust pipes. SOC. ANON. D'ETUDES DES BREVETS ET PROCEDES COANDA-SOC. COANDA, and COANDA, H. July 17, 1936, No. 19866. Convention date, June 16, 1936. [A Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 18, 1937.] Drawings to Specification. [Class 7 (ii)] An exhaust pipe is formed so that its crosssectional shape varies substantially with that of the high speed core of the discharging gases. This is established by ascertaining, at crosssections down a circular-sectioned pipe, the contours of equi-dynamic-pressure with the aid of, for example, pitot tubes inserted at a number of points in each cross-section. The core of high dynamic-pressure will be found to flatten, and in a particular example to take a general helical shape in merging into the flat shape, which continues to the end of the pipe, the intermediate part being kidney-shaped in section. After a pipe has been formed in accordance with the core, the actual optimum shape is arrived at by trial and adjustment on the engine. Specifications 430,134, 446,131, and 478,575, are referred to.

Title: Improvements in or relating to radio frequency dielectric heating
Inventor: TIBBS CHRISTOPHER EVAN MUNDELL
IPC: H05B6/62
Filed: 1960-06-09
Abstract: 922,127. Dielectric heating. RADYNE Ltd. June 9, 1961 [June 9, 1960], No. 20323/60. Class 39 (3). In dielectric heating equipment having a pair of electrodes, an apertured screen is arranged to intercept part of the inter-electrode field, and one of the electrodes is movable with respect to the other electrode and the screen, and may be passed through the aperture in the latter, whereby to enhance the change in power, delivered to load to be heated, which corresponds to a given electrode movement. If the movable electrode 1, Fig. 2, is moved up to above earthed screen 2, by passing through its aperture, the power delivered to a load 3, of imperfect ice cream, rapidly decreases. If the oven constitutes a tuned circuit for its oscillator, movement of electrode 1 with respect to the screen 2 produces an additional change in power delivered to the load, due to the accompanying change of tuning.

Title: Air-blast electric circuit-breaker with breaking gaps in compressed-air containers carried by insulator pillars
IPC: H01H33/32
Filed: 1958-06-25
Abstract: 838,041. Air-blast switches. ALLMANNA SVENSKA ELEKTRISKA A.B. June 25, 1958 [June 29, 1957], No. 20324/58. Class 38 (5). An air-blast switch (Fig. 1) comprises a movable piston 7 carrying a valve disc 11 which engages a sealing ring 5 on a flange 4 of the stationary contact 2, and having radiallyurged contacts 12 which together form a nozzle contact. In operation, compressed-air supplied to space 20 depresses an operating piston 9, thus opening the contacts and valve and allowing compressed-air to flow from container 1 through an escape channel 23 and cooling grid 22, this air opening the member 28 of a breaking valve 10, normally closed by a spring 29. When the piston 9 has reached its lower position, compressed-air flows through a channel 34 past a non-return valve 35 into the space 30, thus closing the member 28 and terminating the air flow from the channel 23. The breaker is closed by a spring 15 on evacuating the space 20, whereupon space 30 exhausts to atmosphere through a channel 33, similar exhaustion of channel 23 then occurring past the valve 10. If desired, the spring actuation of member 28 may cause the valve 10 to be open when the breaking gap is closed. In Fig. 2 the moving contact piston 57 has two coaxial cylinders 58, 61 enclosing a space 67 normally connected through a valve housing 68 to the compressed-air container 51. In operation compressed-air from pipe 86 lifts a membrane 69 to cause a valve member 70 to block the pipe 71 and exhaust space 67 to atmosphere, the compressed-air in container 51 opening the moving contact 57 and its valve disc 62. Simultaneously, compressed-air flows to the space 82 through a throttle 84, to lift the member 79 of a blocking valve 73 and close the compressed-air outlet 74, the throttle setting ensuring that the arc is extinguished before valve closure occurs. Evacuation of the pipe 86 resets the valve 70 to allow closure of the contact 57 by a spring 63, and the delayed opening of the member 79.
Patent GB-1033194-A (GB)
Title: Process for surface-treating iron and steel materials to bestow high acid and wear resistivity
IPC: C25D3/54
Filed: 1963-05-22
Abstract: The surfaces of iron or steel articles are made acid resistant by electrodepositing thereon titanium from an aqueous alkaline solution, e.g. containing Ti(OH)3 or TiF3 in aqueous formaldehyde to which is added hydrazine hydrate and ammonia, and forming first a Ti-Fe alloy layer on the surfaces and then a nitride layer over the alloy layer. After titanium electrodeposition, zinc may be immediately electrodeposited from a conventional bath to completely cover the titanium layer and the articles then immersed in a cyanide salt bath e.g. NaCN at 600-800 DEG C. until the zinc has vapourized shutting off air while the alloy and nitride layers are formed.  Alternatively after titanium electrodeposition, the articles may be heated to 150-400 DEG C. in a non-oxidizing atmosphere to diffuse the titanium into the surfaces prior to immersion in the cyanide salt bath, or the articles may be directly heated to 600-800 DEG C. in an atmosphere containing or yielding nitrogen gas e.g. NH3-H2 mixture until a nitride layer is formed over the Ti-Fe alloy layer.
