Title: Wringers
IPC: D06F45/18
Filed: 1945-12-20
Abstract: 602,221. Wringers. LOVELL MANUFACTURING CO. Dec. 20, 1945. No. 34531. Convention date, Dec. 26, 1944. [Class 138(ii)] A wringer comprises cooperating hollow rolls, a roll - supporting frame which is provided at one end only of the rolls and incorporates a drive head 1, and pressure-applying means for moving one roll relatively to the other. The lower roll consists of a rubber-covered tube 26 carried by a collar 25 on a shaft 20, which extends through a tube 21 projecting from the head 1. Both ends of the tube 26 are flared and the outer end is closed by a cap 30, over which the rubber covering extends. The roll is journalled on the tube 21 by bearings 31, 32, and is adapted to be removed by an endwise pull which overcomes the resistance of a ball-detent 27 on the shaft 20. In order to rotate the tube, a gear 19 fixed on the shaft 20 is adapted to be engaged by two gears 10, 11, which are mounted in a carrier 12 slidable on a drive shaft 5, and either of which can oe clutched to the drive shaft according to the desired direction of rotation of the roll. The upper roll is constructed similarly to the lower roll, and is removably carried on a stub 35 fixed to a sleeve 36. This sleeve carries the outer roll 37 of a ball-bearing 38, the inner roll 39, of which is fixed to a member 40 pivoted to the end of a pressure arm 42 which is pivoted to the frame at 43. The roll pressure is applied through a toggle comprising a pair of pivoted links 44, 46 pivoted respectively to the frame at 45 and the pressure arm 42 at 47. The toggle is operated by a device comprising a link 50, which is pivoted at 51 to the arm 42, and a compression spring 56 mounted between a seat 55 at the free end of the link 50 and a seat 57 pivoted at 58 on the link 46. The link 50 has a handle 52 which projects through a slot 53 in the frame cover 54. Varying degrees of pressure may be applied to the rolls according to the angular position of the link 50, which is provided with a shoulder 61 arranged to engage one of a series of notches 60 in a pivoted latch member 59. The roll pressure is released by depressing a button 63 against a spring 65 so as to move the latch member 59 clear of the shoulder 61. The drive shaft 5 for the wringer is disposed within a depending sleeve 2, which is adapted to be fitted over a wringer post and is provided with an index pin 3 engaging one of a series of holes in a flange on the post for locking the sleeve in any desired angular position on the post. When pressure is applied to the rolls, the lower end of the toggle link 44 is positioned above the upper end of the index pin 3 so that the latter cannnot then be operated to change the position of the wringer. A draining appliance 67 is fastened to the frame adjacent the lower roll.

Title: Radar speed measuring systems
IPC: G01S13/60
Filed: 1974-07-22
Abstract: 1468357 Radar BRITISH RAILWAYS BOARD 22 July 1974 [20 July 1973] 34636/73 Heading H4D In a train- or other vehicle-mounted speed measuring system there are included aerial means for directing a radio beam to the ground and for receiving waves reflected therefrom, means for producing an A.C. signal whose frequency corresponds to the Doppler frequency, and means for processing the A.C. signal to produce an output Doppler pulse train. The processing means includes pulse shaping means 1, Fig. 1, which operates on the A.C. signal to produce a pulse train, a frequency to voltage converter 2 whose input is either the pulse train from the pulse shaping means (connection A) or is derived from the output Doppler pulse train (connection B), and a voltage controlled oscillator 3. Output from the frequency to voltage converter 2 controls the voltage controlled oscillator 3, so that it causes pulses to be inserted in the output Doppler pulse train when there is a discontinuity in the pulse train produced by the pulse shaping means 1. The oscillator commences oscillation at a frequency just less than that of the A.C. signal and decays to zero at a rate which is fast when connection A is used and slow if connection B is used. If appropriate loop gain is provided when connection B is used, the frequency increases with time. In the embodiment shown in Fig. 3, a zero-crossing detector 4 produces a train of rectangular pulses from the input AC.. signal (Fig. 4, not shown). This train is fed to a pulse shaping unit 5, producing a train of positive and negative going pulses (shown inset in Fig. 3) which provide one input to a bi-stable level detector 6. The output of the detector 6 constitutes the output Doppler pulse train, and is also coupled back through a frequency to voltage converter 8, an attenuator 10, an electronic switch 12 with an associated inverting buffer 11, and an integrator 13, to provide another input to said bi-stable level detector 6. The electronic switch 12 is switched to the position shown, where the buffer 11 is in circuit, when the detector 6 is giving its low output and is switched to its other position when the detector 6 is giving its high output. The output waveform from the integrator 13 is triangular and is normally inoperative in switching the detector 6. Should, however, a pulse be missing from the zero-crossing detector 4 the output from the integrator 13 reaches a predetermined threshold value to switch the detector 6 (Fig. 5, not shown). From then on the oscillator comprising the elements 6, 11, 12, 13 will insert pulses into the Doppler pulse train until the pulse shaper 5 is again supplying its regular train of pulses, although if they stop altogether the oscillator frequency will slowly decay to zero at a rate determined by the setting of the attenuator 10.

Title: Process for the production of pyrophosphoryl chloride
Inventor: GRUNZE HERBERT
IPC: C01B25/10
Filed: 1962-09-11
Abstract: Pyrophosphoryl chloride, P2O3Cl4 is prepared by reacting dichlorophosphoric acid, HOPOCl2, or a mixture containing the acid with phosphorus pentachloride, PCl5 in the absence of water.  The molar ratio of dichlorophosphoric acid to phosphorus pentachloride in the initial reaction mixture may be 2 : 1.  The mixture containing dichlorophosphoric acid may be obtained by the partial hydrolysis of phosphorus oxychloride or phosphorus pentachloride, e.g. by the reaction of phosphorus oxychloride with (a) orthophosphoric acid, (b) phosphorus pentoxide and water.  The reaction may be carried out at 10-25 DEG  C. in the presence of an inert liquid diluent, e.g. carbon tetrachloride, pyrophosphoryl chloride being recovered by fractional vacuum distillation of the reaction mixture. Pyrophosphoryl chloride may be used for the production of dichlorophosphoric acid esters, phosphoric acid esters, synthetic resins, dyestuffs and insecticides. A comprehensive review of the prior art is given, and includes references to the preparation of pyrophosphoryl chloride by the oxidation of phosphorus trichloride, PCl3 using dinitrogen tetroxide, N2O4; by the fractional distillation of (a) hydrated phosphorus oxychloride and (b) condensed phosphoryl chlorides obtained by the reaction of phosphorus pentoxide with phosphorus pentachloride; and by the thermal decomposition of dichloro-phosphoric acid by itself and in the presence of phosphorus trichloride, phosphorus oxychloride, and thionyl chloride.

Title: Improved method and apparatus for producing chemical reactions by action of heat
IPC: C07C37/04
Filed: 1920-12-08
Abstract: For effecting chemical reactions by a fusion process, the p  mixture of substances which are to react are caused to travel upon or through a bath of molten metal or alloy heated to the required temperature; or in the special case in which the metal is itself one of the reacting materials, then the other material must necessarily travel through the bath.  The manufacture of phenol is an example of the first type of process, benzene sulphonic acid and caustic soda are fed on to the surface of a bath of molten lead at a temperature of 320 DEG  C. and are depressed beneath the surface of the molten metal by a rotating iron drum as described in Specification 174,974, the rate of revolution of the drum is such that the mixture is submerged for 15-30 seconds and the sodium phenate formed is removed from the drum by a scraper.  The manufacture of sodium nitrite is an example of the special case, powdered sodium nitrate is fed on to a bath of molten lead at a temperature of 450 DEG  C. and is carried through the bath as in the previous example; after 3-5 seconds contact the sodium nitrate is reduced by the lead to nitrite, and the mixture of the latter and resulting lead oxide is removed and separated by leaching. Specification 16834/07, [Class 82, Metals and alloys], also is referred to.ALSO:The manufacture of phenol by fusing together sodium benzenesulphonate and caustic soda is carried out by causing these substances to travel upon or through a bath of molten metal or alloy heated to the required temperature.  Thus the mixture of reacting materials is fed on to a bath of molten lead at a temperature of 320 DEG  C. and is depressed beneath the surface of the molten metal by a rotating drum as described in Specification 174,974; the reaction is complete in about 15-30 secs., and the sodium phenate formed is removed by a scraper from the surface of the drum as it leaves the bath.ALSO:Sodium nitrate is prepared by causing fixed sodium nitrate to travel through a bath of molten lead heated to the required temperature.  Powdered sodium nitrate is fed on to a bath of molten lead at a temperature of 450 DEG  C., and is depressed beneath the surface of the molten metal by a rotating drum as described in Specification 174,974, [Class 64 (i), Heating liquids &c.]; after 3-5 secs. contact the nitrate is reduced by the molten lead, and the resulting mixture of the sodium nitrite and lead oxide is removed and separated by leaching.

IPC: E05B65/19
Filed: 1959-10-14
Abstract: 930,374. Latches. CHICAGO FORGING & MANUFACTURING CO. Oct. 14, 1959, No. 34843/59. Class 44. A batch mechanism comprises a latch plate 1 having a keeper receiving opening 3, a main latch 10, and a safety latch 61, both latches being rotatably mounted on the plate 1 and having keeper engaging portions 20, 62 overlying the opening which, after engagement with a keeper 80 rotate such that keeper retaining portions 21, 63 of the latches overlie the opening, the keeper retaining portion 21 of the main latch lying between the keeper and the keeper-retaining portion 63 of the safety latch when in the latched condition. In operation the keeper 80 moves downwards into the opening 3 and strikes the keeper-engaging portion 62 of the safety latch 61 and causes the latter to rotate about its pivot 60 until a locking abutment 75 of a lever 67 is able to move into and offset 77 due to the rotation of lever 67 about its pivot 70 under the action of spring 65, further rotation of the safety latch 61 thereby being prevented. The keeper continues to move downwards and rotates the main latch 10 against the action of spring 12, the keeper-engaging portion 20 of the latch co-operating with a wall 36 of a lever 30 and causing the latter to rotate about its hinges 31 until it can spring back under the action of spring 32 to lock the main latch. Release of the mechanism is effected by pulling wire 41 which causes lever 30 to be rotated and releases the main latch 10, the keeper then being forced upwards by this latch until it is held by the safety latch 61. Further rotation of lever 30 causes the lever to engage the abutment 71 on the lever 67 and rotate the latter such that the safety latch 61 is released and the keeper is free to be moved clear of the opening 3.
