Title: Improvements in guards for milling machine cutters and analogous machine tools
IPC: B23Q11/08
Filed: 1924-11-08
Abstract: 243,886. Broughton, J. Nov. 8, 1924. Guards.-In guards for milling-cutters and like rotary tools, of the type comprising two angularly-adjustable guard arms each consisting of two or more hinged-together sections, the guard arms are secured to the arm of the milling- machine, or to a like support, by a clamping- device or clip to which the guards arms can be independently attached at different points, in order to adjust also the distance between their pivotal points. The front and rear shields of a guard for a milling-cutter 2 comprise perforated, channel-shaped upper and lower curved sections 3, 4, the flanges 5, 6 of which are extended to form ears 7, 8, 9 to receive pivot bolts 17, 10 provided with spacing-sleeves 19, 11. The bolts 17 secure the shields to any of the bolt-holes 16 provided in a clamp 13, the halves of which are bent up from octagonal blanks and can be drawn together by bolts 15 to grip the usual arms 1 of the machine, which arm may be of various sizes and cross-section. As shown, side plates 22, 23 are bolted or riveted to the shields, but some or all of these may be omitted and, as shown in Fig. 7, perforated lateral extensions 24 may be bolted to the shields 3, 4 for use with wide cutters or " gang " cutters. The guard sections, of which there may be more than two on each side of the cutter, are angularly adjusted on each other and the supporting-clamp 13 by slackening the pivot bolts, which may, however, be replaced by stiff hinge joints. The end pipe passes through one of the holes 20 in the upper section 3, the holes 21 in the section 4 serving for inspection of the work. This section 4 may be raised manually to expose the work, or lifted automatically by linkwork actuated by a cam on the reciprocating work-table. Adjustable supporting-means other than the clamp 13 and arm 1 may be employed. The Provisional Specification describes a form having a single-guard arm, and states that each guard arm may comprise a single section only.

Title: Improvements relating to air filtering and dust-extracting apparatus
IPC: B01D46/04
Filed: 1938-09-15
Abstract: 519,180. Filtering air. BRAND, A. N. Sept. 15, 1938, No 26891. [Class 8 (ii)] Air is delivered to hoppers f of a pair of filter chambers b, c containing dust bags e, and the cleaned air from both chambers normally flows past a valve s to a common outlet chamber d having an outlet k to a fan and to an air delivery duct; from this duct part of the air may be by-passed through a valve to a return duct o leading to a bridge passage communicating with the filter chambers. The duct contains the valve s rotated by the air pressure so that it alternately connects the duct with each chamber shutting it off simultaneously from the chamber d, while the other chamber has free outlet to the chamber d, and is shut off from the duct o. The air supply from the duct collapses the bags in the chamber it supplies. The valve s may be held against the side of the duct by an adjustable degree of friction.

Filed: 1974-06-06
Abstract: 1473083 Data transmission; coding for PSK systems POST OFFICE 6 June 1974 [6 June 1973] 26978/73 Heading H4P A coder particularly for a twinplex four phase system has means for adjusting voltage levels of input data, and clock pulses, with which the data is synchronized. Output data is stored for one clock interval and fed back to give normal binary equivalents of the modulo-4 sum in Gray code on two pairs of outputs having logical complements. The Figure shows apparatus for performing mod-4 sum for any combination of input and immediately previous output. Gray code is not suitable for arithmetic manipulation hence normally Gray must be changed to natural binary; in the present arrangement addition is performed on natural binary inputs and Gray code presented at the output terminals by interchanging connections. The input data stream A is clipped by combined effect of resistors R1, R2 and OR/NOR gate G1 giving complemented outputs to flipflop FF1 and similarly with data stream B with respect FF2, which are clocked and synchronized by pulses 2 through gate G2. NOR gates G7, G8 and OR/NOR G9 together perform an exclusive OR function which is passed, together with the immediately previous output from flip-flop FF4 to a further exclusive OR network network G10-G12. Carry operation is performed by G10 and added in exclusive OR networks G4-G6; this output and immediately preceding output from flip-flop FF3 are fed to a further exclusive OR network G13-G15. Gray code inputs AB are therefore processed and delivered in normal binary code which may be converted back to Gray in a converter (not shown) known in the art. Flip-flops FF1-FF4 are of the clocked type i.e. input is transferred to output at each clock pulse applied to clocking terminals.

Title: Process of producing vinyl chloride
IPC: C07C17/25
Filed: 1945-10-18
Abstract: Vinyl chloride is produced by thermal decomposition of 1 : 2-dichlorethane at 600-650 DEG  C. in a tube with smooth walls in the absence of any catalyst and of any rough surface adapted to promote the decomposition of vinyl chloride to acetylene.  By regulation of the temperature and speed of passage, the decomposition is preferably limited to about 50-70 per cent of the dichlorethane present.  The process is preferably a continuous one.  In an example, dichlorethane including some non-converted from a previous cycle, is passed into a furnace comprising tubular elements with smooth walls, of glass for example, heated to 600-650 DEG  C.  The products are at once detarred and then pass into a water scrubber and thence into a degassing plant from which the dissolved gases are delivered with the vinyl chloride to a cooler and a condenser and are then separated by known methods, whilst the acidulated liquors and the tars dissolved in the unreacted dichlorethane are run into a decanter where they are separated, the dichlorethane being returned to the cycle.

Title: Process for the preparation of isomeric racemic dihydro-nor-iysergic acids
Filed: 1950-11-09
Abstract: The invention comprises racemic dihydronor-lysergic acid and the corresponding-isolysergic acids I and II.  These are made by treating a compound of the formula <FORM:0676281/IV (b)/1> (R=alkyl) with a light metal and acid (e.g. zinc and hydrochloric) to give <FORM:0676281/IV (b)/2> and reducing the latter with sodium and an alcohol (e.g. butanol). The isomers produced can be separated by fractional crystallization or chromatography, preferably in the form of esters.  In the latter case re-esterification of the product is necessary as the group R is split off during the second reduction step (or sometimes during the first).  An example is given of the production of the three isomeric acids and their methyl esters, the acids being regenerated from the latter after purification.
