Title: Improvements in and relating to indirectly-heated steam boilers
IPC: F22B1/12
Filed: 1926-08-09
Abstract: 257,252. Schmidt'sche Heissdampf Ges. Aug. 20, 1925, [Convention date]. Heating by indirect contact of steam; heating by hot liquids.-In a boiler heated by the circulation of steam or other hot medium in one or more closed tube systems, the elements of the tube systems inside the boiler may be readily run out by the aid of a longitudinal support in the boiler to a manhole in the end of the boiler for replacement or repair. To remove the elements 11 inside a boiler 1, first thir connections through the sides of the boiler with the outside elements are broken and then they are supported in turn by a hook 9 carried by a roller 8 on a longitudinal rail 7 and placed on a plate 3 near the manhole 2 ready for withdrawal through the manhole. In a modification, the bottom of the frames 14 around the elements carry rollers which allow the elements to be run out along a plate extending the whole length of the boiler.

Abstract: 658,284. Percussive drills. KIELHOLZ, H. July 23, 1948, No. 19822. Convention date, July 24, 1947. [Class 124] In a mechanically operated percussive tool a cam-shaped lifting element, after compressing a spring placed between a hammer and a bush, is free to revolve relatively to its drive and allow the hammer to strike freely. As shown, a cam 7, driven by gearing 5, 6 from a flexible drive 21. has a runner 12 attached to a striker spindle 14 which passes through a bush 17. An actuating spring 16 is housed between the bush 17 and a hammer 15. A dog clutch 24, 25 between the cam 7 and the gear 6 has sufficient free movement to allow the hammer to strike a free blow after the runner has passed the highest point of the cam. A spring 19 may act as a buffer. In a modification, Fig. 5 (not shown), the drive for the cam, which is formed annularly round the striker spindle, is in the form of a pin, a slot providing free movement. The tool may be driven by a built-in electric motor or internal combustion engine.

Abstract: 531,219. Electron multipliers, circuits for. GENERAL ELECTRIC CO., Ltd., and ESPLEY, D. C. July 13, 1939, No. 20418. [Class 40 (v)] In modulating apparatus utilizing electronmultipliers, the signal varies the primary current of the electron multiplier, and the multiplication factor is varied at a frequency which is a subharmonic of the desired carrier frequency. Preferably the signal is a television signal causing variations in the light falling on a photo-electric cathode ; and the sub-harmonic frequency is applied as a variable voltage to a secondary cathode of the multiplier in such a way that non-linearity between the multiplication factor and the applied voltage causes the production of harmonics in the output circuit from which the desired modulated carrier can be selected by tuning. Specification 531,220 is referred to.

Abstract: 678,205. Ordnance loading appliances. POCOCK, F., BENNITT, W. B., BARRY, F. J. B., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Aug. 10, 1940. [July 13, 1939] No. 20446/39. Class 92 (i). Relates to ordnance loading appliances of the type in which a loading tray carrying a rammer is movable manually from a firing position clear of gun recoil to a loading position in line with the open breech, the charge placed on the tray being then rammed into the breech after which the tray is returned to firing position and the rammer retracted. According to the invention, the rammer is operated by an electric motor and electric means are provided for coordinating the movements of the loading tray with those of the ramming motor so that the ramming movement is precluded except when the tray is locked in the loading position. In the form illustrated, the loading tray 1, carries the ramming motor 3 and cable gear 7, 8 oppositely wound on the motor driven helical drum 6 for operating and retracting the rammer (not shown). The tray 1 is rocked from firing position to loading position and vice versa about a fixed bearing pin 2 the axis of which is parallel to the axis of the gun barrel. Attached to the tray and swinging therewith about pin 2 is a plate 22 carrying a switch 31 for controlling the ramming operation and a similar control switch 30 for rammer retraction. The switches are self-closing but are opened alternately by levers 18, 27 and 17, 26 on a sleeve 19 fulcrumed on the plate 22. The arms 17, 18 are operated through adjustable pins 15, 16 by a nut 13 travelling on a screw 12 on the shaft.of the ramming motor. The ends of the arms 26, 27 are cam shaped to.engage rollers 28, 29 on arms for opening the switches. The closing of the switches for ramming or retraction is also under the control of rollers 36, 35 engaging cams 33, 32 fast with pin 2. Fig. 3 shows attached to a plate 1a on the loading tray, a hand-operated locking bolt 37 spring-pressed to engage holes in the pin 2 to lock the tray in the firing and loading positions, a switch 42 in the circuit of the ramming motor being closed by a projection 40 on bolt 37 only when the tray is locked. An electric circuit diagram for the reversible ramming motor and the controlling switchgear is illustrated in Fig. 4 (not shown).

Abstract: 1,267,298. Fibrillating films. HERCULES Inc. 29 April, 1970 [6 May, 1969], No. 20709/70. Heading B5B. A process for forming continuous filaments by fibrillating a film and simultaneously bulking the filaments involves feeding a ribbon of longitudinally oriented thermoplastic film having longitudinal parallel striations (Fig. 3) at a predetermined speed, surrounding the ribbon with a jet of fluid at a temperature sufficient to plasticize the ribbon without loss of orientation and directing the fluid jet, and thus the ribbon, into a bulking chamber having an open end opposed to the fluid jet and a cross-sectional area sufficient to permit limited lateral movement of the fluid jet. A screen is moved laterally across and in close proximity to the open end of the chamber at a substantially slower speed than the speed at which the ribbon is fed into the chamber and by thus confining the fluid jet to exhaust through the screen randomly deflects the jet and hence the ribbon laterally within the chamber at a rapid rate and thereby fibrillates the film. The resulting filaments are folded on to the screen and are randomly crimped as they are moved out of the chamber by being compressed against the surface of the screen. Suitable apparatus for the process of the invention is that of U.S. Patent 3,457,611, Figs. 1 (not shown), and 2 in which striated ribbon R is fed through yarn-tube 15 and urged into bulking chamber 14 by a fluid jet, which may be steam under pressure, supplied to capillary tube 13 by way of channels 12, chamber 29 and supply pipe 30, 31. The ribbon is substantially completely fibrillated in chamber 14 by random rapid lateral movement induced by deflection of the jet, and thus the ribbon, from areas of the slowly moving screen 3 which are densely covered with fibrillated filaments to areas which are less densely covered. The filaments then pass under the lower surface 35 of the jet unit 2 and are randomly crimped by the pressure of the jet unit on the screen 3. Suitable striated film for use in the invention is that of Fig. 3 which is fibrillated to form continuous filaments of specific cross-section, Fig. 4 (not shown). In an example a ribbon of polypropylene of the above cross-section is fibrillated and crimped using the above apparatus.
