Abstract: 1474642 Controlling light SIEMENS AG 8 May 1975 [30 July 1974] 19355/75 Heading G2F In a display device the volume between two outer plates 1, 3 is divided by a relatively thin plate 2 to form a first chamber 9, containing liquid crystal material and provided with an electrode 4 and segmented electrode 6, and a second chamber 11 including reflective, scattering, fluorescent or phosphorescent material, such material being in a liquid or gaseous state at least when initially introduced into the chamber. Plates 1 and 2 are transparent, but plate 3 may be reflective. A fluorescent liquid in chamber 11 may enable provision of an image on a coloured ground. Alternatively, for specular reflection, chamber 11  may contain liquid mercury or a solidified lowmelting alloy such as Wood's metal. Instead of mercury, the chamber may contain phosphorescent material, for images which appear by day as bright on a dark ground, and as dark on a bright ground at night. Again the chamber 11 may contain a high viscosity liquid containing finely dispersed metal powder. A number of liquid crystal chambers may be provided in series. Plates 1-3 may be of glass, or plate 2 may be of mica. Peripheral U-shaped metal clips 7 on plates 1 and 3 provide the required spacing for plate 2. By making plate 2 as thin as possible, parallax is reduced e.g. if chamber 11 contains reflective material while still isolating the liquid crystal material.

Abstract: 153,386. Richards Thread Milling Machine Co., Richards, G., Burt, L. N., and Freeborn, J. E. Aug. 7, 1919. Milling screws.-In a screw milling machine, a hob k<1> is driven through gearing so coupled to the means for rotating the screw blank, and also to the means for traversing the cutter slide b on the machine bed k, that the relative speeds of rotation of the hob and blank can be adjusted according to the longitudinal travel of the hob, which traverse is intended to enable a workpiece considerably longer than the hob to be cut and to limit the formation of facets on the work. In addition to the longitudinal traverse of the hob provided by the slide b, transverse adjustment is provided by the slide l, vertical adjustment by the slide n and angular adjustment about an horizontal transverse axis by the casing n<1>, the hob-driving mechanism comprising splined shafts a, f, s, toothed gearing, and worm and worm-wheel gearing to allow this. The splined shaft a rotates the work through change-speed gearing, and feeds the slide b through a nut h<2> engaging a fixed screw and driven through a shaft h and worm gear g<2>, the shaft h also adjusting the speed of rotation of the hob through change-speed gear d<3>, and differential gear c<1>. The shaft h may have a forward extension carrying a handle for manual operation, in which case drive from the shaft a is disconnected. Milling-cutters.-When the hob k<1> is set at an angle to the work, about an horizontal transverse axis by tilting the casing n<1>, its surface may be formed convex or concave to work more accuratelv on internal or external screw-threads respectively. In a modified form of machine, the hob shaft is arranged horizontally but at an angle to the work, and a conical hob is mounted on the end of the shaft, by which means more room is provided for stronger spindle-supporting means.

Abstract: 577,879. Bleaching oils and fats. LEVER BROS. & UNILEVER, Ltd. Oct. 20, 1944, No. 20317. Convention date, Oct. 27, 1943. [Class 91] Dark oils and fats are bleached first with an acidic phosphoric compound and an oxidiz:ng per compound and then with a bleaching earth. Preferably the stock is agitated at 'a slightly elevated temperature with both a small quantity of commercial phosphoric acid and a small quantity of hydrogen peroxide solution, until no further bleaching is manifest, and then washed with hot water to remove the phosphoric acid and any colouring matter that has coagulated. The stock may then be dried and bleached with 2 to 6 per cent. of a bleaching earth in the conventional manner. The acidic phosphoric compound may be commercial orthophosphoric acid in concentrations of from 70 to 85 per cent. Other such compounds used may be pyrophosphoric acid and acid salts of phosphoric acids such as potassium or sodium dihydrogen phosphate or disodium dihydrogen pyrophosphate. The oxidizing per-compound may be hydrogen peroxide, or an alkali metal peroxide, perborates or persulphates. Commercial hydrogen peroxide in 30 per cent. solution is used in examples. The proportions of the phosphoric compound and the per-compound may be within the range of .25 to 2 per cent. by weight of oil or fat, .5 to 1 per cent. of each being the optimum range. The bleaching is carried out at a temperature of 60- 70‹C. when the stock is in the liquid state but below the temperature at which charring commences, i.e., 80-90‹ C. The treating time is from one half to one and a half hours. The process may be operated as a batch or a continuous one. Specification 577,880 is referred to.

Title: Buoy position checking
IPC: G01S13/46
Filed: 1974-05-09
Abstract: 1403879 Radar STANDARD TELEPHONES & CABLES Ltd 9 May 1974 20441/74 Heading H4D In a position checking arrangement a control station A, Fig. 1, transmits a radio pulse of frequency f 1  at time t 0 . This is received at a transponder B and causes it to transmit a radio pulse of frequency f 2  at time t 1 . This is received at the station A and ranging equipment there determines the distance AB from the time interval since transmission of the pulse of frequency f 1 . The pulse from the transponder B is also received at the transponder C and causes it to transmit a pulse of frequency f 2  at time t 2 . This is received at the station A, and the distance BC+AC is determined. Each transponder comprises control means for causing it to transmit a pulse of frequency f 2  either in response to the reception of a pulse of frequency f 1  or in response to the reception of a pulse of frequency f 2 . The roles of the two transponders are now exchanged by means of their respective control means, and a pulse of frequency f 1  from the station A causes the transponder C to transmit a pulse of frequency f 2 . The distance AC is thereby determined, and since BC + AC is already known, the distance BC is also determined. The arrangement has particular utility for checking from a shore station the positions of the buoys marking a safe navigation channel. In such a case, one transponder may be provided ashore at a known location (Z), Fig. 3 (not shown). Transponder circuitry, Fig. 2.-A common transmit/receive aerial 20 is fed via a circulator 21, which connects it via a PIN diode switch 22 with the mixer stage 23 of a receiver. The mixer 23 receives from a varactor controlled local oscillator 24 a signal whose frequency is either (f 1 +i.f.) or (f 2 +i.f.), where i.f. is an intermediate frequency, depending upon a control signal from a master clock 25. The mixer 23 feeds an i.f. amplifier 26, the output from which goes to a detector stage 27. The detector output forms a trigger signal for a pulse modulator 28, which is driven by a power supply 29. The pulse output of the modulator 28 opens the switch 22 and causes a transmitter 30 to transmit a pulse of frequency f 2  via the circulator 21 to the aerial 20. The clock 25 is responsible for setting the transponder to one of three states, designated 0, 1, and 2. In state 0 the power supply 29 and the oscillator 24 are switched off. In state 1, the power supply 29 is switched on, and the oscillator 24 is operative at the frequency (f 1 +i.f.). In state 2, the power supply 29 is switched on, and the oscillator 24 is operative at the frequency (f 2 +i.f.). In the arrangement shown in Fig. 1, initially the transponders B, C would be at state 0. At a predetermined time the master clocks would set the transponder B to state 1 and the transponder C to state 2. After a suitable period B would be set to state 2, and C to state 1. The cycle would be completed by both transponders being reset to state 0.
