Filed: 1928-09-13
Abstract: 320,210. Holzverkohlungs-Industrie Akt.-Ges., and Seib, J. Sept. 13, 1928. Aldol; crotonaldelhyde.-In the manufacture of crotonaldehyde by the method in which acetaldehyde is polymerized under alkaline conditions to aldol and the latter is heated, a strong inorganic acid is added to the aldol, before heating, in order to decompose its content of salts of organic acids, the use of a substantial excess of strong inorganic acid being avoided. The salts of organic acids in the aldol are those formed from the polymerizing agent and impurities in the acetaldehyde. Acetaldehyde of an origin, such as that obtained by the carbonization of wood, may be used, care being taken that the alkali added is more than sufficient to react with the acetic acid, methyl formate, and like impurities present. The amount of acid added when the polymerization to aldol is completed is preferably equivalent to that of the alkali. Examples are given.

Patent GB-1545030-A (GB)
Title: Screwing tool
IPC: B25B21/00
Filed: 1977-06-23
Abstract: The device has a screwdriver (1) and means for setting a defined direction of rotation and a defined torque. By a pulse-generator wheel (3) arranged in a rotary manner in the screwdriver (1), two pulses are produced which are converted in a timing circuit into a first and a second signal limited per unit of time. When the signals limited per unit of time are present simultaneously, the screwdriver (1) is switched off via a switching element. This ensures that the screws to be released are unscrewed or just loosened only by a certain amount. The comparison of the pulses with time signals guarantees that the screwdriver is switched off only after the screws are actually released. <IMAGE>

Filed: 1971-04-19
Abstract: 1291967 Colour television FERNSEH GmbH 19 April 1971 [16 April 1970] 26436/71 Heading H4F In a colour television camera employing a plurality of camera tubes, e.g. red, green and blue tubes 1, 2, 3, aperture correction of the video signals is applied in adders 8, 9, 10 using a standard aperture correction circuit 7 fed with that camera tube signal which has the greatest amplitude at the time in question. Prior art correction is stated to have used the output of the green camera tube. This however gave poor correction in blue or red saturated areas. Where a luminance signal is produced, e.g. from a matrix or camera tube, the aperture correction is applied to the luminance signal only (Fig. 2, not shown). Only the horizontal component of the aperture correction may be derived as described, the vertical component always being derived from the green or luminance signals. Only the high frequency components of the signals may be used for the correction.

Title: Improvements in or relating to devices comprising a synchronous motor
IPC: H04L13/04
Filed: 1961-07-21
Abstract: 962,754. Electric synchronous movements; electric motors; control of A.C. motors. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 21, 1961 [July 26, 1960], No. 26560/61. Headings H2A, H2J and H2L. [Also in Division H3] The invention provides apparatus in which a double stator synchronous motor has the movement of its rotor controlled by means of a number cf bi-stable triggers actuated by a control generator. The poles of the two stators are relatively offset by 90 degrees so that if their polarity is varied cyclically, as in Figs. 1a-1d, the rotor 3 steps towards the right. By adjustment of circuit parameters great variation in speed can be obtained. The motor is reversible. In one embodiment, Fig. 2, operation of switch 8 triggers a monostable relaxation unit 52. This in turn triggers an astable relaxation unit comprising transistors 37, 38 which feeds pulses over line 31. Transistor 37, 38 and their associated gating circuits 23, 27 ; 24, 28; 25, 29; 26, 30; are cross-coupled so that the pulses on line 31 switch the various transistors in sequence to give currents in stator windings 4-7 such that the situations illustrated in Fig. 1 are obtained. Thus the rotor steps continuously until the astable unit is stopped, this being done after the return of unit 52 to its stable condition after a time dependent on the circuit parameters. In order that the rotor shall reach synchronous speed during the first pulse on line 31, this pulse is made longer than the others by capacitor 44 having a longer timeconstant than capacitor 43. The circuit of Fig. 2 includes lines 53, 54, the arrangement being such that the astable unit cannot be switched off until there is no negative potential on either of these lines. This occurs only when transistors 10, 11 are conductive, i.e. once every four pulses. Thus if monostable unit 52 resets during the fifth to eighth pulses then the astable unit will produce eight pulses and the rotor steps eight positions. This is stated to be of use in telegraph tape feed apparatus 13. Specification 962,755 is referred to.

Title: Improvements in or relating to a method of providing a ceramic article with a roughened area
Inventor: GANZ RUDOLPH VALTIN
IPC: B28B11/04
Filed: 1951-11-15
Abstract: 702,572. Pottery manufacture. COLONIAL INSULATOR CO. Nov. 15, 1951, No. 26773/51. Class 87 (1). [Also in Groups V and VII] A ceramic article such as a former 1, Fig. 6, for making rubber gloves by the dipping process is provided with a roughened, irregular or decorative surface 8 in relief by the following method. A flexible sheet 2, e.g. of rubber, having on its surface the roughened or other design 4 that is to be imparted to the ceramic article is taken, and the recesses of the design are filled with clay slip 5 or other ceramic material. The sheet is then applied to the (unbaked) smooth ceramic article, the slip being in contact with the article. The slip is then dried, the sheet is peeled from the article (Fig. 5) leaving the slip on the article, and the article is baked to set the slip and unite it with the body of the article. Before the sheet is peeled from the article, glaze may be applied to the latter, the sheet being then peeled off to leave the roughened portion as a glaze-free area and the article being then fired. A glove made by dipping from the form shown in Fig. 6 has a rough thick portion at the palm and insides of the thumb and fingers. When the slip is applied to the unbaked article the latter quickly absorbs moisture from the slip, making it difficult for the operator to position the strip correctly on the article : to obviate this difficulty a light coating of a lubricant such as glycerine may be initially applied to the article. The slip may contain waterglass or other adhesive to ensure that it will amalgamate with the body of the article, and may differ in colour from the article. The roughened area may include trade-marks or lettering. The dipping form may be for making bathing caps or balloons. The invention may be applied to the manufacture of decorated porcelain or ceramic ware.

Abstract: 1382687 Resolution of α-amino-α-phenylacetonitrile SYNTEX CORP 9 June 1972 [10 June 1971] 27148/72 Heading C2C Enantiomers of α-amino-α-phenyl-acetonitrile are obtained by contacting a racemic or optically active α-amino-α-phenylacetonitrile with an optically active tartaric acid in the presence of a C 2-8  alkanoic acid to give the tartaric acid salt of one enantiomter of α-amino-α-phenyl acetonitrile. As the artaric acid salt of oneenantiomer is formed and removed by differential solubility, the other enantiomer racemizes to provide more salt formation. The continuous resolution-racemization provides 100% of the desired enantiomer salt. The process may be effected in a liquid diluent, e.g. a hydrocarbon, chlorinated hydrocarbon, ether or ketone. The resulting tartaric acid salt of one enantiomer of α-amino-α-phenylacetonitrile may be hydrolysed with an acid to give the corresponding acid addition salt of one enantiomer of α-amino-α- phenylacetic acid.
