Abstract: 1293736 Dentures COMFO-DENT CORP 24 May 1971 [31 July 1970] 16635/71 Heading A5R A prosthetic denture comprises a rigid U- shaped frame 12, a plurality of artificial teeth 10 each having bite and base portions 16, 18, and a soft, resilient material 28 bonded to the base portions 18 of the artificial teeth 10, each tooth having a notch portion 14 in the base portion to which the frame 12 is bonded. Method of manufacture. A deformable mesh structure 24 comprising loosely interwoven wires (38) is placed together with the artificial teeth 10 and the frame 12 in a cavity formed by a pair of mould blocks 20, 22 as in Fig. 4. The mesh structure 24 is extended upwardly from the frame 12 to form a skirt structure 26. An elastomeric material 28, preferably silicone rubber, and a curing agent are introduced into the mould cavity to encapsulate the mesh structure 24. Recesses 34 in the mould block, when filled with elastomer, produce arificial gum portions (36) intermediate said teeth. The skirt portion 26 and palate-engaging portion 42 may be deflected to various positions 40, 44, 46, as indicated in Fig. 2, in order to conform with the patients' oral cavity. Additional layers of elastomeric material (48), (50) may be placed on the maxillary and mandibular dentures which are then inserted into the oral cavity and the dentures deformed into close conformity therewith. The maxillary and mandibulary artificial dentures (52), (54) are provided with a Spee's curve of 4¢ inches which may be predetermined by setting the artificial teeth 10 on a frame 12 which is curved to conform to the Spee's curve desired.

Patent GB-415551-A (GB)
Title: Improvements in and relating to the manufacture and production of hydrogen chloride
IPC: C01B7/01
Filed: 1933-06-21
Abstract: <PICT:0415551/III/1> Hydrogen chloride is produced by burning dry hydrogen and chlorine in a completely closed apparatus under substantially increased pressure e.g. 5--6 atmospheres.  The reaction gases may be cooled and then expanded to effect liquefaction or may be absorbed in water &c.  In the apparatus shown chlorine is introduced through an inlet 1 and hydrogen through an inlet 2 and the gases are burnt at the burner 9 where they are ignited, e.g. by an electrically heated wire.  The hydrogen chloride passes through a cooler 15 which it leaves through a valve 16 which may be controlled together with the valves of the inlets 1, 2.  A safety valve 13 is provided to deal with fluctuations of pressure.  Safety devices such as wire nets may be provided in the neighbourhood of the burner to prevent striking back of the flame.  The hydrogen chloride issuing from the valve 16 may pass on to an outlet 25 or may pass into a trickling device 21 in countercurrent to an absorbent e.g. water, alcohol, hydrocarbons supplied from a tank 23.  Thus concentrated aqueous hydrochloric acid may be prepared and withdrawn at 26.

Patent GB-219477-A (GB)
Title: Improvements in screw propellers
IPC: B64C11/24
Filed: 1923-07-10
Abstract: 219,477. Leitner, H. July 10, 1923. Screw propellers.-Hollow metal detachable screw propeller blades are constructed from plates or tubes which are folded around one another at the butt end and decrease in width until a joint is formed along the centre of the blade. Two plates a, b, Figs. 1 and 2, are pressed to form the trailing and leading portions of the blade, the parts being riveted together at e along the middle of the faces. The plates at the root ara wide enough to be formed into complete cylinders, the cylindrical part c of the. portion a fits within the cylindrical part d on the portion b and is riveted or otherwise secured thereto. In a modification, the leading and trailing edges are straight and the blanks before pressing are formed with a V opening at the butt end, so that the root of the blade is of tapered form. Instead of plates, slightly conical tubes a, b, Fig. 8, may be used, each tube being suitably flattened to aerofoil shape and being cut away for three-quarters of the length and slightly less than half the width so that an overlapping joint at e is provided. The tubular ends are bent round and secured to a flange l on a fitting k which constitutes the cylindrical root. A longitudinal internal stiffening girder connecting the two faces may be added to the preceding constructions. In one form, the girder is constructed from strips o, p, Figs. 10, which are of channel form with abutting webs riveted at q, the flanges of the channels being enlarged and brought into curved form at the butt ends. The blade plates may be of taper gauge and/or made up of laminations.

Filed: 1954-06-17
Abstract: 756,797. Aircraft rotor blades and aerofoils. SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES DU SUD-EST. June 17, 1954 [June 19, 1953], No. 17855/54. Class 4. [Also in Group VIII] A rotor blade for a rotary wing aircraft comprises a tubular spar 1 having a root portion 4 of substantially cylindrical shape embedded within and soldered to a root attachment sleeve 19 to which it is secured also by a nut 21, the portion 4 extending into a tapered section 5 and an extended length 6 of substantially constant ovoid section which may be twisted throughout its length. Sleeves 24, formed by wrapping plastic material reinforced by layers of glass fabric and provided with embedded lightening cores such as 25, 26 of balsa wood are moulded on to the spar length 6. The sleeves which may be moulded with an excessive thickness of material subsequently removed by profiling or moulded initially to the finished profile, are divided spanwise in abutting relationship and they are secured by bonding to trailing edge box members 2 which carry attachment flanges 32, 51b. The members 2 also have lightening cores 49 and they are provided with integrally moulded spanwise webs 7, 8 and dished end closure panels 13. The gap 50 between adjoining edges of the members 2 and the corresponding cavities formed between the dished panels are filled with sponge rubber or cast cellular material which completes the aerofoil profile and permits relative movement between adjoining members 2 resulting from drag distortion of the blade. The leading edge of the blade is protected by sheet metal panels 3 overlapping the transverse edges of the members 2 and the tip end of the spar carries a fish-plate 15 for the attachment of balance weights 17. In a further embodiment, (Fig. 6, not shown), the sleeves 24 and box members 2 are moulded integrally. The invention is applicable to aerofoils other than rotor blades.

Title: Improvements in carburetters for internal-combustion engines having a device for supplying additional fuel during periods of engine acceleration
IPC: F02M1/00
Filed: 1945-07-12
Abstract: 595,993. Catburetters. KITTLER, M. J., and ENSINGER, R. L. July 12, 1945, No. 17875. [Class 7 (iii)] Means for supplying additional fuel during periods of engine acceleration, Fig. 1, comprises a fuel chamber 11 connected to a source of fuel under pressure and provided with an outlet valve 12 and a second fuel chamber 18 communicating with the first fuel chamber through a restricted passage 28 and having a flexible end wall 20, a spring controlled piston 15 between the chambers and manual means 23 associated with an engine throttle valve for flexing the wall of the second chamber to control the spring controlled piston the piston being operatively associated with the outlet valve whereby the latter is opened for a time depending on the strength of the spring 17 associated with the piston. Fig. 2 shows an induction passage including a pair of geared throttle valves 34, 35. A lever 45 attached to the shaft of a gear 43 which operates the throttles carries a roller 46 operating upon an arm 47 constituting an extension of the arm 23 which operates the mov-. able wall 20. This lever is connected to a piston 21 (Fig. 1) and through a spring 22 acts upon the diaphragm so that when the throttle valves are opened the diaphragm is pressed into the chamber 18. A non-return valve 29 enables the chamber 18 to be refilled when the throttle valves are closed. A relief valve 48 is provided to prevent an excessive quantity of fuel being discharged if the throttles are opened too quickly: A valve 30 which controls a connection between the chambers 11 and 18 is opened when a lever which controls the richness of the mixture is in slow running cut-off position and this renders the device inoperative when the lever is in this position. The normal fuel nozzle is shown at 36.
