Title: Improvements in or relating to benzene hexachloride production
IPC: C07C17/38
Filed: 1952-04-16
Abstract: Benzene hexachloride is recovered from benzene solutions of benzene hexachloride which are contaminated with iron, by vaporizing the benzene in the presence of an amine.  Preferably the amine is a tertiary aliphatic amine of 3-18 carbon atoms such as trimethylamine, tripropylamine, tributylamine, triamylamine or trihexylamine and is present in the proportion of about 1-6 molecules per atom of contaminating iron.  The amine reduces decomposition of the benzene hexachloride due to iron contamination, particularly in high temperature recovery processes wherein benzene is distilled off at temperatures up to 150 DEG  C. and above.  In examples (1) and (2) a solution of benzene hexachloride in benzene containing traces of ferric chloride is distilled at 150 DEG  C. in the presence of tri-n-amylamine.

Patent GB-846849-A (GB)
Title: Improvements in or relating to filters for electromagnetic wave energy
IPC: H01P1/213
Filed: 1959-03-20
Abstract: 846,849. Waveguides; microwave filters. WESTERN ELECTRIC CO. Inc. March, 20, 1959 [March 28, 1958], No. 9702/59. Class 40(8). A filter for reflecting waves in a band below a given frequency comprises a rectangular waveguide 10 which is tapered in two dimensions at right angles in such a manner that equal orthogonal components of a wave at any frequency within the band are reflected at different cut-off points spaced axially a quarter wavelength along the guide, whereby the reflected wave is polarized at right angles to the incident wave. The waveguide 10 has a square section at A-A where it is dimensioned to have a cut-off frequency below the lowest frequency in a channel # 1 . The guide tapers in a horizontal plane from A-A to a section C-C where it is dimensioned to have a cut-off frequency for vertically-polarized waves just above the channel f 1.  The guide also tapers in a vertical plane from B-B to D-D where it has a cut-off frequency for horizontally-polarized waves at the same frequency just above the channel f 1.  The sections A-A, B-B and C-C, D-D are axially spaced from each other by one quarter wavelength at the mid-band frequency of the channel f so that horizontal and vertical components of frequencies within the channel suffer a differential phase-shift of 180 degrees upon reflection. Thus input wave energy polarized in the direction of arrow 37 at 45 degrees to the sides of the guide 10 are rotated through 90 degrees upon reflection in this guide and are coupled into the output shunt guide 26. A septum 27 prevents transmission of the reflected waves into the input guide. Wave energy in bands f 2,  f 3 ... .f n,  all higher than f 1 , is transmitted through the guide 10 to a further output guide 15. In order to achieve a constant phase difference over the widest possible band the tapering of the guide 10 may be modified e.g. by deforming it at chosen points. The frequency dispersion caused by the guide 10 may be corrected by passing the components of the band f through a waveguide having a cut-off frequency close to the lowest frequency in the band. Components of the other bands emerge at E-E as an elliptically polarized wave as a result of the higher cut-off and faster phase velocity in section C-C to D-D to which the vertical polarization is exposed as compared with the lower cut-off and slower phase velocity in section A-A to B-B to which the horizontal polarization is exposed. This phase difference is corrected by the circular output guide 15 which has a cut-off frequency equal to that of section C-C to D-D for the vertically polarized wave. The guide is loaded by two quarter-wave conductive fins 16 which raise the cut-off frequency for the vertical component to the same value as the cut-off frequency for the horizontal component in the section A-A to B-B. In a modified arrangement, two orthogonal pairs of fins are used, those in the vertical plane being one quarter wavelength longer than those in the horizontal plane. The ends of the fins are tapered.

Filed: 1970-03-02
Abstract: 1300133 Fuel injection pumps ROBERT BOSCH GmbH 2 March 1970 [28 Feb 1969] 9859/70 Heading F1A A fuel injection pump has a reciprocating and rotating pumping and distributing piston 3, and its delivery is regulated by a spill passage 14a, 14b controlled on the "hydraulic stop" principle by a slide valve 12 which is displaced against spring 26 by fuel from an auxiliary piston 15, the fuel returning through lines 22, 20 and via a temperature compensated variable throttle 23. The throttle cross-section may be varied by means of a threaded stem 25, or at a fixed setting of the stem, by expansion or contraction of a section 30 between the stem 25 and spool valve 24. Low  temperature fuel supplied to the pump during starting causes contraction of 30 and opening of the throttle, thus delaying the "hydraulic stop" and allowing excess fuel to be delivered. In a further embodiment Fig.2 (not shown) the valve spool and stem are directly connected, and the stem attached to a segment of a disc. The disc is adjusted to cause axial movement of the stem via a pin or a further segment connecting the first segment via a thermally expansible segment.

Title: Improvements in or relating to a sheet feeder
IPC: B65H3/10
Filed: 1955-04-05
Abstract: 768,884. Feeding sheets. HARRISSEYBOLD CO. April 5, 1955 [April 7, 1954], No. 9910/55. Class 100(1) In sheet separating and feeding apparatus wherein sheets are separated from a pile 10 by a rotary suction wheel 16 and then fed by an endless conveyer over a feed table 43, 45 to front register stops 46, the wheel 16 and conveyer are driven synchronously at speeds varying from a minimum speed above zero to a maximum and back to a minimum during each cycle, and the taking of a sheet from the pile by the wheel 16 and the registration of a preceding sheet against the stops 46 by the conveyer recur at about the minimum speed. The distance between the stops 46 and the front edge of the top sheet of the pile 10 is equal to, or a multiple of, the circumference of the suction wheel 16. A number of nozzles 66 direct blasts of air at the top front end of the pile and tend to cause the top sheet to press against the underside of a plate 13. The sheet is then gripped by the rotating wheel 16, which protrudes through a slot in the plate 13, and is fed between a conveyer roller 40 and a gravity roller 38. The roller 40 has the same peripheral speed as that of the suction wheel 16, and drives belts 39 which pass over 'the feed table 43 and around a roller 44. The stops 46 are shown as situated adjacent an impression cylinder 47 of a printing- machine. To ensure that sheets arrive at the stops 46 at the correct time, the suction wheel 16 can be adjusted circumferentially relative to its driving shaft 17; a scale and pointer facilitate this adjustment. The wheel 16 has a series of lateral holes 31 which communicate with radial openings, the holes 31 being adapted to register one after another with a port in a suction fitting 34 mounted on a fixed bracket 35. The driving arrangement comprises a gear 50, which is secured on the cylinder 47 and has a pitch circle diameter equal to the diameter of that cylinder, adapted to drive a gear 53 through gears 51, 52. The gear 53 has a radial slot 56 therein engaged by a roller 60 secured on another gear 57 mounted on a shaft 58 which is offset from the axis of the gear 53, whereby the gear 57 is driven at varying speeds, during each revolution of the constant speed gear 53. The shaft 17 of the suction wheel 16 is driven by chain-and-sprocket gearing from the gear 57, and the latter engages a gear secured to the shaft 65 of the conveyer roller 40, the arrangement being that the surface speed of the conveyer .belts and the peripheral speed of the suction wheel 16 are the same.
