Title: Improvements in frusto conical diaphragms
Inventor: TURNER PHILIP WILSON
IPC: F16J3/02
Filed: 1957-08-15
Abstract: 883,295. Diaphragm pistons. MOULTON DEVELOPMENTS Ltd. Oct. 6, 1958 [Aug. 15, 1957; Dec. 30, 1957], Nos. 25818/57 and 40345/57. Class 122 (1). [Also in Group XXXII] In a method of constructing a flexible diaphragm or rubber-like material reinforced with cord fabric, one or more circular blanks of rubberized cord fabric having parallel cords are cut and wrapped in such a manner that a fabric cone is obtained in which the cords overlap symmetrically. Semi-circular pieces 1, 2, Fig. 1, of parallel cord fabric are cut with the cords 3 parallel to a diameter 4. These pieces are wrapped into cones. Two or more of these cones are then superimposed, Fig. 3, to give a structure in which the cords cross everwhere at right angles as shown at 5. The included angle of the cone is 60 degrees. In an alternative form of construction, a circular blank 6, Fig. 5, of rubberized fabric having cords 7 is cut radially along the line of cords as at 8. The blank is then folded round three times to form a three-ply truncated cone with an included angle of approximately 39 degrees, the cut edges of the blank being secured parallel to one another, one inside and one outside the cone on the same radius. In this construction the cords cross one another at an angle of 60 degrees. In a third construction, two circular blanks of rubberized cord fabric are each cut as in the method above described and are each folded one and half times in such manner that each forms a truncated cone having an included angle of approximately 84 degrees. The cones are then assembled one inside the other so as to form a three-ply construction. The cut edge of the inner side of the outer cone is parallel to and on the same radius as the outer cut edge of the inner cone, and the outer cut edge of the outer cone is diametrically opposite to the inner edge of the inner cone. The plies cross one another at 60 degrees. A bead wire may be incorporated in the outer edge of all the cones described. A conical metal insert 21, Fig. 12, may be moulded into the diaphragms constructed as above. A skin of sealing rubber 23 is placed on the inner surface of the diaphragm and a butyl liner 24 is also provided. A stud 25 attached to the metal insert serves to locate the diaphragm in use. Specification 870,489 is referred to.

Title: A process for the production of nitrite esters of non-phenolic organic compounds
IPC: C07C201/04
Filed: 1938-09-07
Abstract: 509,204. Polynitrites. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Sept. 7, 1938, No. 26193. Convention date, Sept. 17, 1937. [Class 2 (iii)] Monophenolic polynitrites are made by treating polyhydroxy compounds with nitrous acid in an aqueous medium, the products being removed from the medium as soon as they are formed. The solubility of the product may be diminished by adding a salt, or, if a higher nitrited product is desired, acetic acid may be added to increase the solubility of less nitrited esters. The nitrous acid may be made in the medium by adding an alkali or calcium nitrite and a mineral acid or acetic acid or nitrous anhydride may be introduced. Suitable polyhydroxy compounds are glycerol, alpha-, #- and dimethyl glycerols, pentaerythritol, methyl tricarbinol methane, erythritol and its monoacetate, monoethyl ether and monochlorhydrin, and hexyl erythritol, from all of which polynitrites containing a free hydroxy group may' be prepared ; and ethylene, propylene, trimethylene, isobutylene, #-butylene, alpha- and #- methyl trimethylene, diethylene and #-methylene trimethylene glycols, glycerol monoethyl ether and monoacetate, and erythritol dichlorhydrin; polyhydroxy compounds containing carboxyl groups are also suitable, such as monomethyl tartrate, dimethyl racemic acid and dihydroxy maleic acid.- Substances such as sucrose which contain many hydroxy groups are not suitable, but sucrose containing a hydrophobic group such as an alkyl group is suitable. An example describes the production of ethylene glycol dinitrite.

Abstract: 518,329. Control of D.C. motors. ENGLISH ELECTRIC CO., Ltd., BINNEY, E. A., CORNER, H. S. POUND-, and SEDGFIELD, H. B. Sept. 8, 1938. No. 26225. [Class 38 (iii)] Varying electromotive force.-In a system, in which traction motors 7, 7b are accelerated by a buck and boost machine 6 until they can be transferred direct to the line by closing switches 11, 11a and opening switch 9, and thereafter the machine 6 is used to excite shunt fields 7d, 7e by raising switch 10, the arrangement is such that the fields 7d, 7e are initially excited by the machine 6 so as to maintain constant current in the motors 7, 7k and finally are excited so as to give the motors a series characteristic. After switch 10 is raised, switch 13 is lowered so that field 6a of machine 6 is energized partly by live current through resistance 14, and partly by the machine 6 itself in series with an exciter 6 and a rectifier 12. After the switches 11, 11a are closed, the motors continue to accelerate, the field 5a of the exciter causes the current in the field 6a to gradually reduce and thus the fields 7d, 7e to be weakened so as to maintain constant armature current. After the current through the exciter 5 becomes zero it tends to reverse, but is prevented by the rectifier 12, so that thereafter the field 6a is only excited by the small steady current through the resistance 14. Whereupon motor fields 7d, 7e receive a steady small excitation, so that the motors operate with a series characteristic due to their series fields 7a, 7c. A.reverse rectifier 15 and reverse field 5d prevent an excessive voltage occurring across the exciter 5 when the rectifier 12 blocks the circuit. Regenerative braking is secured by reversing the excitation of the separately excited field 5b of the exciter. Specifications 509,041, 509,138, 509,239, 514,433, and 514,789 are referred to.

[Class 98 (i)] In a photographic shutter combined with a photo electric exposure meter, the parts of the exposure meter other than the photocell, are built into one or more drum-shaped housings coxially mounted on the rear collar of the shutter housing. The main housing 8 and the front lens support 9 enclose an annular space 10 in which are located the' photo-cell 1 and the mechanical part of the shutter. A drumshaped housing 11 is mounted on the lens support 8a and contains an indicating instrument 13, a permanent magnet 14 and a variable resistance 17. The pointer 15 of the instrument may be observed through the window 16, and a pointer 18 on the ring 18a controls the resistance. Two diaphragms 6, 7 provided with half crescent shaped vanes are arranged in front of the photo-cell 1, and are respectively connected to the speed-adjusting and diaphragm-adjusting members of the shutter. The pointer of the instrument is brought to a fixed mark by adjustment of the speed and diaphragm members. In a modification, the rear housing is divided into two or more housings which may contain some of the parts of the shutter mechanism in addition to the parts of the exposure meter. A window obliquely mounted in the rear wall of the rear housing for observation of the pointer, is also described. The Specification as open to inspection under Sect. 91 also comprises several different means of mounting the sensitive cell. In one example, the cell is mounted, in its own casing coaxially with the lens support, and may be of annular or semi-annular form. The casing may be in front, on, or behind the shutter casing. The cell may also be accommodated in a casing which is hinged to, and may cover, the lens aperture. When folded back from the lens, the casing presents the photo cell to the light. This subject-matter does not appear in the Specification as accepted.

[Also in Division F2] A metering valve 101 for delivering measured quantities of liquid, such as oil in a pressure lubricating system, comprises a, housing 102 having an inlet 114 and an outlet 132, and an expandable sleeve 115 normally contracted into contact with a ball valve 116 and a separate diaphragm 117 dividing the housing into first and second chambers 138 and 122 respectively connected by a passageway 126 in the diaphragm. The open upper end of the chamber 112 is covered by the resilient diaphragm 117 which is clamped to the housing 101 by a transparent cover 118. In operation, when pressurized liquid, e.g. Oil is supplied from a container 1 under the action of a pump piston 11 and is fed via a passage 109 to the inlet 114 the ball valve is forced against a seat on the diaphragm, thereby closing the passageway 126, the sleeve then expanding so as to permit the flow of liquid to act on the diaphragm and fill the chamber 138, liquid on the other side of the diaphragm being forced through the outlet 132. Upon a reduction in pressure in the inlet, the ball moves away from the seat and thereby allows the liquid in the chamber 138 to pass via the port 126 and passages 129, 135, to the outlet. Various sized discs 137 may be fitted above the diaphragm in order to limit the movement of the latter and so alter the capacity of the chamber 138.
