Title: Improvements in or relating to matrix-setting and type-line-casting machines
IPC: B41B7/18
Filed: 1933-05-02
Abstract: 398,775. Type-bar-making machines. TYPOGRAPH GES., 17, Huttenstrasse, Berlin. May 2, 1933, No. 12778. Convention date, July 6, 1932. Addition to 398,451. [Class 100 (iii).] Assembling matrices ; driving-mechanism.- In the apparatus described in the parent Specification, the adjustment of the ramp-rail, by which the level of the matrix-bars is determined, is effected independently of the controllever by the depression of keys. The controllever 2, Fig. 2, is rigidly mounted on its shaft 4, and the cam 11, that adjusts the ramp-rail, is, as heretofore, slidably mounted on the shaft, and is adjusted by a lever 14 and a link 15. The other end of the link is connected to a lever 18, Fig. 3, which can be adjusted to any one of three positions by means of three keys 33, 34, 35. The lever 18 is normally maintained in its highest position against a stop 20 by a spring 21. The lever can be held in either of two lower positions by pivoted catches 24, 25. which are normally held in operative position in contact with stop-pins by springs. The catches have arms 30, 31, which can be engaged by pins on the key-rods, to depress the catches out of operative position. Each of the keys is adapted to depress the lever 18 into its lowest position. One of the keys also depresses both of the catches, so that the lever returns to its highest position. A second key depresses the lower catch 25, so that the lever is arrested in an intermediate position by the catch 24. The third key does not affect the catches, so that the lever is arrested in the lowest position by the catch 25. The keys may be connected together in known manner, so that an operated key is locked in depressed position until released by the striking of another key.

Title: Improvements in self-adjusting mechanism for hydraulic wheel brakes
Inventor: TAYLOR ARTHUR GEORGE
IPC: F16D65/54
Filed: 1953-05-07
Abstract: 731,757. Automatic adjusting mechanism for brakes. H. & T. INDUSTRIES, Ltd. Feb. 3, 1954 [May 7, 1953], No. 12791/53. Class 103 (1). In a self-adjusting mechanism mounted in the hydraulic wheel brake cylinder of an internal shoe-drum brake, the device comprises two pistons 1; one of which carries a central spigot 2 which projects axially therefrom and is formed with ratchet teeth 3. The piston carrying the spigot is provided with a protuberance 4 adjacent the spigot on which is mounted a sealing washer 5. The second piston is formed with an axial extension 6 which is provided with an axial blind boring 7 into which the spigot enters. The extension 6 also provides a mounting for a second washer 5a; both sealing washers 5 and 5a providing a good seal under pressure of the hydraulic fluid which enters the fixedly mounted cylinder 18 through a boring 8. The extension 6 is formed with an annular groove 9 into which is fitted a pawl 10 (Fig. 4). A circlip 14 is then pushed over the end of the extension 6 into a position in which it springs into the groove 9 and forms a shoulder against which the pawl 10 can abut, its movement being thus restricted to the width of the groove. The pistons and their associated parts will be maintained in the position shown by the usual coil springs (not shown) which hold the brake shoe 17 out of engagement with the brake drum. On depression of the brake pedal, fluid is forced into the space between the pistons and, as a result, the pawl 10 will move into engagement with the circlip 14 and then if wear has occurred on the faces of the linings the inwardly turned extremities 13 of the pawl will over-ride on one or more teeth on the ratchet which will have the effect of reducing the clearance between the linings and the drum when the brakes are not in operation, thus compensating for wear. The clearance between the linings and the drum will thus finally be determined by the width of the groove. Two alternative constructions are illustrated and described in the Specification; one being such that the cylinder is mounted for axial movement and the hydraulic fluid acts between a single piston and a transverse wall of the cylinder, the latter carrying the spigot 2; the other construction being of the kind used in connection with two leading brake shoes, there being two fixed cylinders arranged diametrically opposite one another, each cylinder forming an anchorage for a pivotally mounted shoe. A modified form of pawl is also described which permits a finer degree of adjustment.

Title: Improvements in or relating to the propylation of toluene
IPC: C07C2/68
Filed: 1956-05-02
Abstract: Isopropyltoluene fractions containing at least 40% of the para-isomer are prepared by reacting under non-equilibrium reaction conditions toluene with 0.5-0.9 mol. of propylene in the presence of 0.01-6% by weight of the total hydrocarbons of aluminium chloride at 0-50 DEG C. and separating isopropyltoluenes from the higher polyalkylbenzenes. The higher polyalkylbenzenes may be disproportionated under equilibrium conditions in the presence of toluene to produce a mixture containing 70% meta-, 28% para- and 2% ortho-isomer. Phthalic acids are prepared by oxidation of the isopropyltoluene fraction produced with air using a manganese acetate-ammonium bromide catalyst in acetic acid at 180 DEG  C. and 300-400 p.s.i.g. for 4 hours.  The solid acids are separated by filtration and washed with acetic acid.  The vapours leaving the reactor are passed through ice-cooled traps and then condensate is mixed with the acetic acid washings, distilled to remove acetic acid and recycled to the reactor.  From the mixed acids phthalic acid is removed by heating to form the anhydride which is volatilized and the iso- and tere-phthalic acid separated by acetic acid extraction or fractionation of the dimethyl esters.

Title: Secondary radar systems
IPC: G01S13/78
Filed: 1964-04-01
Abstract: 1385178 Radar FERRANTI Ltd 29 March 1965 [1 April 1964] 13513/64 Headings H4D and H4L A secondary radar system comprises a transponder responsive to a coded transmission from  an interrogator. The transponder, Fig. 1A, provides two responses for each radar signal from the transmitter. The first is a radar reflection of the coded signal and the second is a radio transmission, separately coded, which,  when received at the interrogator radio receiver serves to indicate that the transponder device is friendly. Doppler shift of the radio frequency at the interrogator may be used to indicate the relative velocity of the craft carrying the transponder. To prevent enemy signals giving a  friendly indication, two parallel discriminating channels are employed at the radio receiver Fig. 1B, which discriminate against a signal  using the correct code system but the incorrect sequence. Additionally, gates at the receiver are blocked by an enemy high power transmission. The radio transmission coding is effected  by a binary word store 12 at the transponder which provides a non-destructive read out. The word store produces a 180 degree phase-shift modulation of the radio transmission in accordance with the stored code. At the interrogator radio receiver a word store 22 contains the same code as the transponder store and effects demodulation in antiphase to that at the transponder of the received radio signal to cancel out the phase reversals. The timing of  the initiation of the receiver decoding is effected by the reflected radar signal being receiving at 20.
