Abstract: 172,932. Zocher, C. Dec. 16, 1920, [Convention date]. Mechanical toys. - A toy or advertising device consists of a picture or drawing on a surface or backing, the parts of which can be displaced in relation to one another to alter the picture. As shown, the surface is formed by the edges of a strip of material coiled into a spiral or serpentine. A face is drawn on the surface in such a manner that the features are unsymmetrically placed in respect to the centre of the coil. By displacing the coils relatively to one another, or by pressing the surface out from its plane, the expression of the face is altered. Lines are drawn on the back of the coil to assist in restoring it to its original form.

The pulping-machine 1 is driven by the engine 8 and is supplied with hot water from a tank 23 connected with the engine water which receives cold water from a tank 22 fed by a pump driven by the engine. The engine also drives an air compressor for the sulphur burner 12 and a vacuum pump (not shown) connected to the filter 15 and to the vacuum apparatus 20 for drying the crystals of boric acid. Sulphur dioxide escaping from the pan 3 passes to a scrubber 30 charged with borate of lime which when spent, is removed and fed to the pulping-machine.

IPC: C07C205/59
Filed: 1947-10-23
Abstract: Diphenyl ethers of the general formula <FORM:0642159/IV (b)/1> are obtained by reacting a quaternary salt of the general formula <FORM:0642159/IV (b)/2> with a phenol of the general formula <FORM:0642159/IV (b)/3> wherein RN is a tertiary base which may be aliphatic, partly aromatic or one in which the nitrogen is part of a heterocyclic ring, e.g. pyridine, diethylaniline, the picolines, the dimethylpyridines and trimethylpyridines, R1 is one of the groups <FORM:0642159/IV (b)/4> or <FORM:0642159/IV (b)/5> where Z is an alkyl group containing not more than four carbon atoms and Y an acyl group normally used to protect an amino group, R11 is one of the following groups: H, -OH, alkyl, alkoxy, NO2, carbalkoxy, acyloxy and acylamino, and X is the anionic of an aromatic sulphonic acid, hydrochloric acid, hydrobromic acid or hydro-odic acid.  The reaction may be carried out in solvents having a dielectric constant of less than 25, e.g. liquid sulphur dioxide, liquid ammonia, benzene or an excess of the tertiary organic base.  The reaction may be effected by using the components of the quaternary salt without the isolation of the quaternary salt itself.

Abstract: 1414926 Servicing requests INTERNATIONAL BUSINESS MACHINES CORP 15 June 1973 [29 June 1972] 28489/73 Heading G4A  When one of a plurality of features in a data handling device requests service, the main programme causes sequential addressing of subroutines, each corresponding to a feature which may be associated with the device, and simultaneous interrogation of the feature, each subroutine causing service of the feature requested or an immediate return to the main programme if service is not requested or if the feature is not in fact associated with the device. As each feature is interrogated, a branch in the main programme causes an instruction address register (22, Fig. 1, not shown) to address an associated location in a read only store (21), an instruction decoder (25) decoding the read out instruction when the feature requires service so that a sub-routine is executed. If service is not required a gate is enabled to effect a return to the main programme. If the feature is not present the highest order bits of the word read from the store are zero, and decoded to again effect a return to the main programme.

Title: Improvements relating to measuring devices for railway tracks
Inventor: ELLIS STAFFORD MALCOLM
IPC: E01B35/00
Filed: 1956-09-18
Abstract: 829,831. Rail gauges. ELLIOTT BROS. (LONDON) Ltd. Sept. 12, 1957 [Sept. 18, 1956], No. 28558/56. Class 106 (2). Apparatus for gauging railway track comprises a measuring probe 10 carried on a car 13 movable along the track and held in contact with the inner side face of one of the running rails, the path of the probe 10 being controlled by a guide probe 14 which is arranged in staggered relationship with respect to the measuring probe 10 and is engaged by the outer side face of a guard or check rail 23 associated with the other running rail. The probes 10, 14 are carried on rods 11, 15 slidable in bearings 12, 16 fixed to the car 13 and the rods 11, 15 are pivoted to a lever 17 pivoted at 18 to the car 13. The probe 10 is biased outwardly by a spring 19 and normally contacts a rail such as 22, but is guided over gaps and other hazards by the probe 14 engaging a guard rail such as 23. The degree of staggering of the probes 10, 14 is chosen to avoid the fouling of all known hazards and the connection of the rods 11, 15 to a suitable lever 17 compensates on curves for placing the probes off the central transverse axis of the car 13. The movement of the probe 10 relative to the car is applied to a transducer 21 to provide a proportional electric signal and variations may be recorded. In a practical embodiment, Fig. 3, two measuring probes 25, 26 and their respective guide-probes 27, 28 may be carried by vertical rods extending downwards from hydraulic jacks for lifting and lowering them, the jacks being slidably mounted on transverse rods 31, 33. The jacks carrying the probes 25, 27 are connected to a lever 46 by links 45, 50 and those carrying the probes 26, 28 to a lever 53 by similar links. The levers 46, 53 are pivoted at 47 and can be moved inwards by hydraulic jacks 52, 54 against the action of springs 51. To enable the guide probes 27, 28 to move inwards too they are each connected to the other lever 53, 46 by links 55 and the links 50, 55 are given a degree of lost motion by their telescopic construction, the links 50 also having springs 56 tending to shorten them within limits imposed by the links 55. The horizontal rods 31, 33 and two others disposed vertically above them are secured in plates 35, 36 attached to the car frame by lugs 38, 39, 42 pivotally received in brackets 40, 41 and 43 to prevent twisting of the car frame from distorting the rod assembly. The provision of a guide probe enables the usual three-foot shoe to be replaced by one of three inches, thus making the probe sensitive to small variations.
