Abstract: 413,331. Road - traffic signals on vehicles. HEINEMANN, R., 35, Hindenburgstrasse, Wilmersdorf, Berlin. Jan. 13, 1933, No. 1257. Convention date, Oct. 25, 1932. [Class 118 (ii).] In manoeuvre-signalling devices of the kind wherein a pivoted signalling- arm and its operating solenoid are mounted so as to be removable from the casing as a unit, the carrier for the solenoid and the arm has upwardly-extending side lugs 4 which are forced against the front wall of the casing 1 at 5 when a securing screw 7 is tightened, the carrier 2 bearing at 6 on the rear wall of the - casing. The locking-means for the signal arm comprises a locking-member 16 resting against a roller 22 carried by a pin 24 fixed in a flat spring 23. A lug 33 pressed out of the casing bottom is forced against a length of metal tubing 34 to hold the same to receive the connecting cable. A celluloid side plate 36 on the signalling arm may be turned on a pivot 35 in order to change the lamp. Specifications 340,830 and 364,439 are referred to. The Specification as open to inspection under Sect. 91 comprises also constructions in which the lugs 4 are fastened by riveted projections or by notches to a cross-bar pushed over the upper edge of a recess formed in the coachwork. The lugs 4, Fig. 8 (Cancelled), may be connected to lugs 42 on a cross-bar 47 having a recess to enable it to be pushed under a rivet 46 in the carriage body plate. Alternatively, the cross-bar 47 may have a projection which engages a recess. Fig. 12 (Cancelled) shows the carrier 2 fitted with lugs 51 and fastening members 50. This subject-matter does not appear in the Specification as accepted.

Title: Manufacture of para-aminobenzene-sulphonamido-pyrimidines
IPC: C07D239/69
Filed: 1943-01-26
Abstract: p - Aminobenzenesulphonamido - pyrimidines are made by reacting a benzenesulphonylguanidine parasubstituted by an amino group or a group convertible thereto by hydrolysis or reduction, with b -diketone or with a tautomer or functional derivative thereof. If desired, the para-amino group is formed from a parasubstituent by hydrolysis or reduction.  Parent materials mentioned include 1 : 3-dialdehydes, 1 : 3 - keto - aldehydes, 1 : 3 - diketones, 1 : 3 - aldehyde-carboxylic acids, 1 : 3-keto carboxylic acids, and 1 : 3-dicarboxylic acids.  Tautomeric compounds which are also included as starting materials are oxymethylene aldehydes and carboxylic acids and their functional derivatives such as alkali salts, acetals, mercaptals, imino compounds, ethers or corresponding thio-ethers and esters.  Specific compounds referred to are 3-oxyacrolein, formylacetone, formyldiethyl-ketone, diethyl - acetyl - acetaldehyde, iso - capronyl - acetaldehyde, acetylacetone, propionyl - acetone, imino - acetylacetone, formyl acetic acid, acetoacetic acid esters, acetonoxalic esters, malonic acid esters, or malonyl chloride, and cyclic compounds such as oxymethylene cyclohexanone.  The reaction may be carried on in either the presence or absence of a solvent. Para-substituents convertible by hydrolysis or reduction into an amino group include acylamino, nitro and azo groups.  In examples, p - acetylaminobenzenesulphonyl - guanidine is reacted with (1) acetylacetone; (2) sodium oxymethylene acetone; (3) b -ethoxyacrolein diethylacetal; (4) diethyl malonate.  In each of these cases the p-acetylamino group is converted to the amino group by hydrolysis; (5) p-nitrobenzene-sulphonyl-guanidine is reacted with acetylacetone and the product reduced.  In the above examples, the product which is obtained is 2-(p-aminobenzenesulphonamido)-4 : 6-dimethylpyrimidine, examples (1) and (5), example (2) the 4-methyl compound, example (3) the unsubstituted compound, and example (4) the 4 : 6-dioxy-pyrimidine.

Abstract: 1489715 Monitoring apparatus in a machine BBC BROWN BOVERI & CO Ltd 15 Jan 1976 [17 Jan 1975] 01584/76 Heading G1N [Also in Division H1] A monitoring apparatus in a machine having a rotating part comprises measuring transducers e.g. thermistors located in or on the machine part, a rotarv transformer having a rotor winding 11 which is coupled to the machine part for rotation therewith and a threshold-value circuit 14 connected to the measuring transducers and the rotor winding 11  and being rotatable, in use, with the machine part. The threshold-value circuit is provided with means, e.g. transistors 66, 67, for converting the output signals of the transducers into threshold-value signals. A control circuit 33 is connected to a stator winding 6 of the rotary transformer, the control circuit 33 being operative to supply power to the thresholdvalue circuit by way of the rotary transformer and to detect the threshold-value signals, whereby to produce monitoring signals. As disclosed two sets of thermistors are used as transducers each set having different response temperatures and each set being connected across terminals 29 of circuit 14. The transistors 66, 67 normally conduct but on successive temperatures being reached in or on the machine part the transistors 66, 67 cease conducting such that successive threshold-value signals are provided. These threshold-value signals activate alarm relay 56a and triggering relay 57a respectively, the former causing an alarm signal to be emitted and the latter causing the machine to be protected, e.g. by closing it down. Three thermistors may be used in each set and the circuit as shown in Fig. 7, simplified, Fig. 8a (not shown). In a modification of the control circuit the current is measured by a resistor with the aid of a mainssynchronous field-effect transistor switch Fig. 8b (not shown). In this case the values for alarm and triggering purposes are set by means of two potentiometers.

Abstract: Vitamin B12 is obtained by the anaerobic fermentation of a bacterial nutrient medium in which one or more strains of Methanobacteria are fermented in or on a medium containing at least one nutrient directly utilizable by said bacteria and isolating the Vitamin B12 thus formed.  Specified Methanobacteria are Methanobacterium Omelianskii, and in addition strains of Methanobacteria which act symbiotically with M. Omelianskii are employed.  As nutrient an alcohol or a substance convertible thereto, e.g. a carbohydrate are employed.

Title: Improvements in or relating to folding device for laundered articles
IPC: D06F89/00
Filed: 1962-01-18
Abstract: The folding device of the parent Specification is modified in that the photo-electric cell and the light source of each switching unit are arranged in a single housing beneath the folding table whilst reflecting means e.g. mirrors are arranged above the table.  Light rays from the source pass through openings in the table and are reflected back from the mirror means to the cell.  Interruption of the light rays by articles moving along the folding table cause operation of the folding means.  By putting each light source and the corresponding cell in the same housing independent adjustment is avoided.  Means are provided whereby articles overlapping two or more folding lanes interrupt light rays of a preselector switching unit so as to link up folding means in adjacent lanes.  In this way the device may be used to fold for example these narrow width articles, one narrow and one wide or one very wide article.
