Filed: 1944-12-15
Abstract: 594,353. Speedometers. SELFPRIMING PUMP & ENGINEERING CO., Ltd., and MOUTRAN, F. Dec. 15, 1944, No. 25254. [Class 106 (iii)] [Also in Group XX] The speedometer comprises a stroboscope adapted to produce two series of momentary views of an observed vibrating or rotating object under the control of a rotary lobed cam actuating two pairs of contacts set at an angle to each other, the phase difference between each flash of the two series being an angle of 360 other than - where a is the number of cam a lobes. The views may be produced by providing a flash of light each time a break occurs at either pair of contacts. The flashes occur at unequal time intervals, the relative positions of the object when illuminated thereby indicating whether the speed of the stroboscope is synchronous with that of the object or is an harmonic thereof. As shown, a discharge lamp 1, e.g. a neon lamp, is connected to a transformer 3 also connected to a battery 4 through a make-and-break device 5 of the type described in Specification 557,551, [Group XX], driven through a shaft 16 by an electric motor 7, connected through a variable resistance 10 to mains 9 and provided with a speed indicator 8. The device 5 comprises a cam 11 which co-operates with pairs of contacts 12, 13 set at an angle to each other so that the tuning of contacts 13 is displaced relatively to that of 360 contacts 12 at a phase angle of other than - a degrees defined above. The contacts 12, 13 are so disposed that each makes and breaks contact at the time when a break occurs at the other pair. A condenser 6 bridges the device to prevent arcing and to enhance the electrical impulse at a break, while a switch is included in the connection to contact 13 to allow of speed checks. The Specification describes views presented by a rotating arrow as object when the stroboscope is run at different speeds on each side of and including the speed of the arrow.

Title: Improvements in or relating to double-action distillation
IPC: B01D3/00
Filed: 1946-08-29
Abstract: <PICT:0626659/III/1> The process for alcoholic distillation of the parent Specification in which a must is divided into two portions, one being distilled under atmospheric pressure and the other under reduced pressure, the resulting phlegms being admixed and rectified, is modified when treating musts of low alcohol content, such as aero-yeast and paper-mill lyes, in that the vapours from the vacuum distillation are condensed in the portion of must being fed to the distillation under atmospheric pressure.  One part of the must contained in a tank T is fed through line 26 and preheater G1 into the vacuum column A which is provided with plates, and there distilled under reflux from condensers D and F.  The uncondensed vapours pass through line 10 into mixer P1 where they enrich the other part of the must, drawn from tank T through line 2S, which is then pumped through, and preheated in, condenser D and preheater S1 and fed to the atmospheric distillation column B, the vapours from which are rectified in column C.  The supply of heating steam to column B is governed by regulator W controlled by the temperature of column A, thus to provide condensed water in vessel R which is passed through blow-off valve U to condenser J, there to be vaporized and led through line 21 to heat the column A.  Regulator V under the control of column B provides steam to that column to maintain the required working pressure.

Title: Improvements relating to processes for decomposing lignin
IPC: C08H5/02
Filed: 1954-09-01
Abstract: Distillable phenolic products are obtained by the decomposition of lignin by continuous treatment with hydrogen at temperatures of 350-600 DEG  C. and pressures of 300-1000 atmospheres in presence of water and of an iron salt with sulphur in the anion as catalyst. The water may be simultaneously introduced into the reaction chamber together with reaction mixture, i.e. dried lignin, a sludging or paste-forming agent and a catalyst.  Alternatively the water may be added to the mixture before reaction or moist lignin may be used.  In examples, a mixture of Scholler lignin, calcium oxide (to neutralize the acid in the lignin), ferrous sulphate and xylenol is ground to a paste, is pumped into the bottom of a vertical electrically heated reaction tube together with water and hydrogen under pressure, the mixture is removed at the top of the reactor, is condensed and separated (the hydrogen being recycled) and the reaction product (i.e. a solution of the decomposition products of lignin in xylenol together with emulsified water, calcium sulphate and catalyst) is fractionally distilled to give a phenol-containing oil.

Abstract: 704,485. Clocks. TAVANNES WATCH CO. SOC. ANON. Nov. 13, 1951 [June 29, 1951], No. 26526/51. Class 139 A time-piece including a swinging lever carrying a pawl controlling a ratchet wheel to actuate the winding-up gear of the barrel is characterized by a rod pivotally secured to said swinging lever by a guiding member for said rod, by winding-up means adapted to impart a reciprocating movement to said guiding member and by two coil springs mounted around said rod and operatively connecting said rod with said guiding member 'for transmitting the reciprocation of the guiding member to the rod' and therethrough to the swinging lever, said coil springs transmitting the movement only until the ratchet wheel has completely wound the barrel spring through the winding-up gear. A pin 4, Figs. 1 and 2, fixed to a lug 5a integral with a tubular member 5 engages a circular groove in the hub 2 of a wheel 1. A rod 6 having a piston-like head 7 slides inside the member 5 and is screwed to a U-shaped member 9 to which a lever 11 is pivoted at 10. A coil spring 28 'surrounds the rod 6 between the head 7 and the closed end 5b of the tubular member 5 and a second spring 29 surrounds the rod 6 between the end 5b and the member 9. As the wheel 1 rotates the tubular member 5 is reciprocated and the springs 28, 29 cause the rod 6 to follow the movement and this movement is transmitted to the lever 11 by the member 9. The lever 11 carries a pawl 23 which steps-on a ratchet 18 as the lever 11 swings in the direction of the arrow 30, Fig. 2. Spring .detents 24, 25 prevent reverse rotation of the ratchet 18 the clockwise movement of which is transmitted via the spindle 15 and a gear 19 to the barrel ratchet 20. When the mainspring in the barrel 21 is fully wound movement of the tubular member 5 merely results in the tensioning of the spring 28 no operative movement being imparted to the lever 11.
