Title: Improvements relating to Gas Heated Flat Irons.
Inventor: HABICHT FRANZ PAUL
IPC: D06F75/02
Filed: 1916-01-04
Abstract: 100,004. Habicht, F. P. Jan. 5, 1915, [Convention date]. Reversible gas hand-irons.-Relates to means for reversing and securing the alternative heating-surfaces in the acting position. The reversible heating-surfaces are pivoted on the gas pipe c, which also carries the handle h. A slotted rod m, pivoted at l, embraces a conical member f on the handle shaft. An enlargement at the upper end of the slot permits the rod to be pushed so far on to the cone by the spring p that it is secured against axial movement. To reverse the iron, the rod is pushed forward in the direction of the arrow, Fig. 1, until the main portion of the slot is free to move over the cone. The rod is then pulled axially until it takes up a position symmetrical with that shown in Fig. 3, and then is automatically re-locked by the spring when released.

Abstract: 283,136. Del Riccio, L. Jan. 4, 1927, [Convention date]. Projection screens; optical-projection apparatus; kinematograph apparatus; optical apparatus.-A projection screen is provided with means for varying its. effective size, and the size of the image projected thereon may also be varied. Fig. 2 shows a projection screen 6 partly covered by border sections forming a black mask covering the parts of the screen which are not in use. The sections comprise a fixed bottom section 13, a vertically movable top section 17, and side curtains 15, 16. The section 17 is carried by ropes 24 passing over pulleys 35 and supporting a counterweight 38. The curtains 15, 16 are carried by fixed hangers 22, and by hangers from rollers 18 running on rails 20. Movement of the curtains is effected by a continuous rope &c. 25 passing over pulleys as shown, the curtains being respectively secured to oppositely moving reaches 31, 32 of the rope 25. Simultaneous movement of the section 17 and curtains 15, 16 is effected by connecting the rope 25, as at 43, to an endless belt 39<a> passing over pulleys 39 which are secured to the pulleys 35 and are of smaller diameter than them. An indicator 44 may be provided on the rope 25 to indicate on a scale 45 the position of the curtains &c. The screen mav be used in conjunction with two projectors to enhance projection effects; e.g., if a kinematograph picture of boats moving towards the spectators is being displayed, the projected image may be enlarged in size by changing the projector in use, and the effective size of the projection screen may be progressively increased. The two projectors, one throwing an image fitting the smaller screen area and the other the larger area may be provided with a shutter having apertures permitting their alternative use. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a projector provided with a mask having a continuously variable aperture and a projection lens system adjustable to vary continuously the scale of the projected image. The mask, Fig. 6 (Cancelled), comprises two overlapping plates 53, 54 cut so as to form a rectangular display aperture which may be varied in size by simultaneously moving the plates along guides parallel to a diagonal of the aperture, the guides 'being formed in an apertured support. A rotary disc 58, having a handle 58a and cam slots 61 engaging pins 62 on the plates, may be provided for moving the plates. The mask aperture may be varied in correspondence with the screen area. Fig. 8 (Cancelled) shows a projecting lens system which may be employed to vary the enlargement of the projected image, two lens combinations 73, 76 being movable along a rod 75 by means of cam slots 77a, 78<a> in members carried by a rod 79 rotatable by a hand wheel 80. This subjectmatter does not appear in the Specification as accepted.

IPC: F04D25/00
Filed: 1945-01-02
Abstract: 605,449. Automatic pressure control systems. MINNEAPOLIS - HONEYWELL REGULATOR CO. Jan. 2, 1945, No. 188. Convention date, Feb. 22, 1943. [Class 38 (iv)] The pressure of the air supplied to an engine by a power-driven compressor depends on several variables including one which is a function of the length of time during which the compressor speed exceeds a predetermined value. As shown, the turbine 27 driving the compressor 12 is controlled by a gate valve 31 operated by a motor 36 for adjusting the amount of exhaust gas from the engine 10 byepassed from the turbine, and the motor 36 is controlled by the amplifier 42 connected to a bridge network including variable resistances 78, 87, 76 and 73. Resistance 78 is adjusted according to the pressure in the carburetter 16 and as the adjustment may tend to overaccelerate the turbine when a pressure drop occurs, an acceleration responsive device 103 adjusts resistance 76 to counteract the tendency, while the motor 36 itself adjusts resistance 87. Resistance 73 is provided to enable the range of pressure to be manually adjusted. The acceleration responsive device is so constructed that the position of the'slider of one control rheostat depends on the length of time that the compressor speed has been above a predetermined value. Specification 605,450 is referred to.

[Class 100 (ii).] In a process for treating the surfaces of plywood to be printed in imitation of other woods, the colour and structure of two or more pieces of plywood are matched or rendered uniform by bleaching one or more of the pieces, accompanied, where required, by the use of transparent pore-fillers, slightly-coloured varnishes or like means, in order that the matched pieces of wood may serve together as a basic surface or surfaces for the reception of the printed impressions. The top layer of the plywood is preferably a knifed veneer, consisting of a light-coloured wood such as alder, birch, East Prussian lime, or maple, and the remaining layers may be dark-coloured wood such as fir or pine ; the bottom layer is preferably a cedarlike wood such as Gabun mahogany. Before or after making up the plywood, the top layer is bleached by heat treatment or by means of an ammoniacal solution of hydrogen peroxide, a pore-filling composition comprising either glue or gelatine and chalk is applied to the surface, and a base coating of colourless or slightlycoloured varnish is applied before printing, the varnish being chosen to suit the ink ; e.g., where a nitrocellulose ink is used, the base coating consists of nitrocellulose varnish. A photomechanical printing process is preferably employed, and when the impression is dry or while it is still damp, an extremely fine film of varnish is applied by spraying under heavy pressure followed by a protective varnish layer applied in the usual way. The protective coatings may be cellulose ester or ether varnishes where a nitrocellulose ink is employed. Other printing processes such as lithography, embossed printing, plate printing, or transfers may be employed.
