Title: Process for the manufacture of cresol ethers alkylated in the nucleus
IPC: C07C41/30
Filed: 1931-11-10
Abstract: Nuclear alkyl derivatives of cresol ethers are prepared by treating cresol methyl or ethyl ethers with alcohols containing more than two carbon atoms in the presence of dilute sulphuric acid.  The alkylation is effected with 50-80 per cent sulphuric acid at temperatures of 20-120 DEG  C., the weaker acid requiring the higher temperatures.  If any sulphonation occurs, the sulphonic groups are split off by hydrolysis.  Examples are given of the production of 1-methyl-3-methoxy-4-tert-butylbenzene from m-cresol methyl ether and isobutyl or tert-butyl alcohol, and of thymol methyl ether from m-cresol methyl ether and propyl or isopropyl alcohol.  Specification 373,896 is referred to.  The Specification as open to inspection under Sect. 91 (3) (a) describes also the treatment of cresol ethers in general and the use of sulphuric acid of any concentration.  This subject-matter does not appear in the Specification as accepted.

Title: Hydraulic shock absorbing system for vehicles
IPC: B60G21/073
Filed: 1931-11-12
Abstract: 392,202. Preventing lateral tilting of vehicles; hydraulic shock-absorbers. DEUTSCH, F. A., 27, Rankestrasse, Berlin. Nov. 12, 1931, No. 31357. Convention date, Nov. 12, 1930. [Classes 108 (ii) and 108 (iii).] One-way fluid shock - absorbers on opposite sides of a vehicle are interconnected in such a way that they function normally as long as the frame and axle move parallel to one another, but any tendency to depart from parallelism results in one shock-absorber rendering the other one double acting. In the construction shown in Fig. 1, each shock-absorber comprises an oscillating vane 5 connected to the axle, movable in a cylinder 1 carried by the frame of the vehicle, the two working chambers a, b being connected by a passage 3 having a one-way valve 4. The passage 3 may be closed by a slidable valve 6 which is normally kept clear of the passage by a light spring and only closes it under the influence of a fluid under pressure supplied from the compression chamber a of the apparatus on the other side of the vehicle through a pipe 8. Simple up and down movements of the frame result in equal movements of the vanes 5, downward movements being free while the rebound is checked by the closing of the valves 4. If, however, one side of the frame tends to rise, the pressure thereby exerted in the compression chamber a of the apparatus on the rising side operates the valve 6 of the apparatus on the falling side and thereby closes the passage 3 on that side so as to check the falling movement. In a modification the valve b is arranged to move axially of the spindle carrying the vane 5. In the construction shown in Fig. 4, the vane is provided with a movable slide 14 pressed outwards by a light spring. The underside of the slide 14 communicates with the compression chamber through a passage 13 and one-way valve 12, this passage 13 being closed at times by the axially slidable valve 6. When the vane moves in an anticlockwise direction, the vacuum formed behind it lifts the valve 12 and draws the slide 14 away from the wall of the cylinder thus allowing free movement. Movement of the vane in a clockwise direction is strongly resisted. The valves 6 are operated to close the passage 13 as required by pipe connections to the apparatus on the opposite side of the vehicle. In a modification shown in Fig. 5 each shock-absorber is of the reciprocating piston type and functions in a simllar manner, the flow of liquid taking place through an intermediate chamber. A further modification is shown in which two oscillating vanes and two abutments are provided, opposite chambers being connected by passages in the operating spindle, while the passage of liquid takes place through an intermediate chamber. The pipe connections between shock-absorbers on opposite sides may be replaced by mechanical or electrical connections.

Abstract: 711,475. Coating webs and yarns. FRANKLIN & SON, Ltd., W., and CLARKE, L. J. Dec. 13, 1951 [Dec. 27, 1950], No. 31401/50. Class 140 Textile material in the form of a web, or one or more ribbons or yarns, is passed, as part of a dyeing process, through a number of cells each containing a small volume of treating liquid and providing a long, vertical, U-shaped path for the material, fresh treating liquid being regularly injected into each cell in such a way as to create zones of turbulence passing like waves through the body of treating liquid. As shown, a cell 3 containing a body of treating liquid L is supplied with fresh liquid through pipes 14, 17, and nozzles 18, the injected streams from which divide when they strike a V-shaped, or triangular-sectioned bar 19 to produce turbulent zones which pass with wave-like motions up to the top of the cell. The injection may be continuous or intermittent. ,Excess liquid overflows through pipe 16. The bar 19 is the lowest member of a frame which consists of two side members 5 connected by a top rail 9 and spacer bars 6. The material to be treated passes around a rotatable roller 7. In order to compensate for shrinkage of the textile material in its travel through the cell, an extension 9a of the top rail engages a slotted arm 10a of a lever connected either to a counterpoise weight or to a speed control. Spaced pegs 4 are provided when yarns or ribbons are treated. The textile material may receive a similar or different chemical treatment in different cells. Adjustment of the shade obtained is possible by varying the speed of travel of the material in response to visual observation of a small sample of dye liquor. Alternatively, variations in an electric current passing through a sample of a treating liquid in accordance with variations in its content of some chemical salt, may actuate either speed controls or valves. A group of cells may be mounted in a heated water. bath. Mangling and draw rollers may be provided at points in the apparatus.

Abstract: 1,223,421. Sets. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 12 July, 1968 [12 July, 1967], No. 32021/67. Heading H4J. A telephone set uses either the microphone 3 (Fig. 1) or the receiver 5 to produce tone calling signals and the base 2 is formed with a recess 4 in which the housing of the transducer used for tone calling is located when the handset lies on the base 2 in its normal position, the housing and the walls of the recess 4 defining a cavity which provides acoustic enhancement of the tone calling signals. If the handset is positioned wrong way round (Fig. 2) the other recess 6 provides as great acoustic enhancement. In either replaced position a member 2a operates a gravity switch. If the handset is replaced askew it will either engage member 2a to operate the gravity switch or will fall away from the base 2, depending on the incorrect position. With slightly askew replacement, inwardly sloping and rounded side walls of the recess 6 will make that part of the handset 1 in engagement with the side walls tend to slide so that the handset tends to align itself centrally on the base 2. A 2À7 kc/s tone is generated by a transistor oscillator during "on-hook" calling. The oscillator includes a transistor amplifier which amplifies speech currents when "off-hook" the changeover being effected by member 2a. Preferably a rocking armature or moving coil microphone is used for tone calling.
