IPC: H01H35/26
Filed: 1964-06-15
Abstract: 1,045,566. Fluid actuation of switches. METZENAUER & JUNG G.m.b.H. June 15, 1964 [Aug. 7, 1963], No. 24664/64. Heading H2B. A fluid pressure responsive electric switch comprises two diaphragms 10, 12 having a common pressure inlet 14 and each actuating a snap-action switch.

Abstract: 1,255,563. Separating hydrocarbons. INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS. 15 May, 1969 [15 May, 1968], No. 24905/69. Heading C5E. [Also in Division C6] A hydrocarbon cut (specified) is contacted with urea in suspension or dissolved in a mixture of nitrile, monocarboxylic acid (optional) and water. The solid complex of urea with nparaffins formed, is separated from the residual hydrocarbon and from the major part of the water or water-nitrile mixture, in a cyclone, and the complex is destroyed by heating to recover the n-paraffins. A gas oil containing 11% by weight of linear paraffinic hydrocarbons was treated with a mixture of urea, acetonitrile and water. The complex of linear paraffins with urea was separated off and then decomposed by heating at 70 C. to give a hydrocarbon phase containing 89% by weight of linear paraffins, the complement consisting essentially of iso-paraffins.

Title: Improvements in or relating to dynamo-electric machines
IPC: H02K5/132
Filed: 1930-08-20
Abstract: 355,509. Centrifugal pumps. COOPER, T. L. R., 45, Woodville Gardens, Ealing, London. Aug. 20, 1930, Nos. 24913 and 33683. [Class 110 (i).] A centrifugal pump B driven by an electric motor A on a vertical shaft S which is submerged in the liquid being pumped is provided with a conical ejector V which removes any fluid that has collected around the shaft connecting the motor and pump. The shaft is without gland or packing. The delivery fluid from the pump B is discharged through a passage T, to a cooling jacket D, and, together with the cone V prevents fluid from leaking up the shaft to the motor chamber. A float K raises a valve J, when the pump is stationary, to close the motor chamber from the fluid chamber. While stationary, a valve I on the driving shaft S rests on a seating on the casing. The shaft is raised magnetically, or otherwise, when the motor is started. The valve K may be opened by centrifugal force. The cooling oil for the motor is contained in a sump M. In an alternative arrangement, the suction eye of the impeller faces upwards, and the difference in pressure on the two sides of the impeller is utilized to raise the shaft S off its valve seat I, when the pump is running. A number of intake and delivery passages may be allowed around the pump. Specification 272,292, [Class 110 (i), Centrifugal and screw fans &c.], is referred to.

Title: Improvements in or relating to side car or like wheeled carrier attachments to motor cycles
IPC: B62K27/02
Filed: 1924-10-21
Abstract: 244,555. Stevens & Co. (1914), Ltd., A. J., and Hayward, C. W. Oct. 21, 1924. Rod couplings. - The frame members of a motor-cycle side-car chassis are secured to one another by jointing-brackets which carry the wheelaxle or the cycle-frame connecting tube and can be clamped by a single nut. The construction avoids brazing and facilitates packing for transport. According to one construction the axle tube 3, Fig. 2, enters split sockets 10, Fig. 1, inbrackets 2 to which the cycle connecting tube 7 and the wheel axle W respectively are attached. The ends of a U-shaped front frame member 8 abut against the lugs of the socket 10 and contain a split tube 29 and conical-ended pin 11 upon which a nut 12 is threaded. When the nut 12 is tightened, the member 8 is drawn firmly against the socket 10 and the latter is clamped securely upon the axle tube 3. The front of the member- 8 is supported from the cycle by a cycle-frame connection 18 secured by clamps 19. In a modification, Figs. 6 and 7, the ends of a double axle 24 are inserted through slots 23 in the brackets 22 and are clamped by two wedge sleeves 25 when the nuts 12 on the pins 11 in the tube 8 are tightened. The brackets may, alternatively, be clamped on the ends of the U-shaped tube by nuts on pins in the axle tube, and in this case the longitudinal outer part of the U-shaped tube may extend rearwardly beyond the axle to be secured to the rear of a frame surrounding the wheel and carrying a bearing for the outer end of the wheel axle.

[Class 49.] A vessel 1, for the treatment of materials such as food in containers, is fitted with an internal spiral pathway 2, divided into sections each of which starts on a lower level than the termination of the preceding one. The containers are carried down this pathway by arms 3 projecting from bosses 4 on a revolving spindle 5 to within a short distance of the wall of the vessel 1 ; the arms pass through the gaps 6 between the various spiral sections. Steam is admitted through inlet 9 and water of condensation leaves through port 10. The spindle 5 is geared to valves 7, 8 through which the cans are fed into and out of the vessel 1 in order to avoid loss of steam. The vessel may be divided into two parts by a valve similar to valves 7, 8 to enable different pressures to be used.

Title: Production of synthetic resins

Filed: 1925-10-12
Abstract: 261,522. Chemische Fabriken Dr. K. Albert Ges., Amann, A., and Fonrobert, E. Oct. 12, 1925. Phenol-aldehyde condensation products; dioxydiarylmethanes.-A condensation product obtained by reaction between a phenol and a ketone is treated in an alkaline medium with an aldehyde or a substance giving rise thereto, at a temperature not exceeding 80‹ C. to produce a resinous condensation product which is precipitated by addition of acid. The resinous products are soluble in a number of solvents and may be air-dried or heated, with or without admixture of filling materials, to transform them into insoluble, infusible products. According to an example, phenol and acetone are allowed to stand, with addition of hydrochloric acid, and the precipitated dioxydiphenyldimethyl-methane is dissolved in alkali and treated with formaldehyde at atmospheric temperature; after 24-100 hours the condensation product is precipitated by addition of hydrochloric acid. Dioxydiphenyldimethylmethane may be treated similarly with paraldehyde and benzaldehyde. Other examples describe the treatment with formaldehyde at temperatures not exceeding 80‹ C. of dioxydiarylmethanes prepared from phenol and methylethyl ketone, phenol and dibenzyl ketone, and p-cresol and acetone. The properties of the products depend to some extent on the amount of formaldehyde used and on the nature of the precipitating acid, those obtained with carbon dioxide, for example, being more brittle than those obtained with hydrochloric acid. The products may be precipitated on or in the presence of other materials. Reference has been directed by the Comptroller to Specifications 18824/12 and 199,528.

The batt is sprayed with water whilst on a foraminous conveyor, then embossed between rigidly and spring mounted rolls. The root and land areas of the rolls are aligned. Oil at 155‹F-170‹F is passed through each roll.  The batt is then passed through rolls having aligned raised portions for providing edge seals extending across the web and other rolls for longitudinal sealing. A cross-linkable acrylic latex, containing hard and soft adhesive, ammonium chloride and a wetting agent is sprayed onto each side in turn while suction is applied to the other side, before or after the edge sealing. After curing at 300‹F and slitting along the seals, non woven fabrics are produced having high loft regions in which the binder is substantially confined to the edges, separated by a network of narrow, highly compressed regions in which the whole thickness contains binder.

The size of the impedance determines the shape of the radiation pattern by attenuating zero and even order Fourier components of the current in the loop, so that a cardioid or circular pattern is formed in preference to the common "figure of eight". The loop may comprise two conductive strips 3, 4 joined by cross pieces 5 so that it has large effective width but reduced series inductance and shunt capacitance. The resistor may be soldered in a break in the strips. A low-noise amplifier, housed in box 6, may be provided at the termination of the loop for an improved signal to noise ratio. Arrays of such loop antennas having phase diferences between adjacent loops may provide further enhanced directivity (Figs. 12-14, not shown).
